INTRODUCTION 



It is a generally recog- 
nized fact that less 
ground grain is re- 
quired to produce a 
given amount of milk, 
meat, or work, than 
whole or unground 
grain. The average 
saving in whole grain 
by the use of the feed 
grinder, has been plac- 
ed by a prominent au- 
thority at 12'/^; many 
single instances show- 
ing the amount saved 
to be as high as 35 7o- 



The mission of the feed 
grinder is to so prepare 
or treat the grain that 
its full nutritive value 
can be wholly utilized 
for all feeding purposes 
on the farm. A trial of 
the machine forcibly 
emphasizes its value. 
A complete descrip- 
tion, with numerous il- 
lustrations of the chief 
points of merit of the 
International Feed 
Grinders are given in 
the following pages.

The International Feed Grinder 



International feed grinders are built in two types, B and C. Type B is designed 
especially for grinding corn on the cob. This style of mill is built in two different sizes— one 
with 8-inch grinding plates and a larger size with 10-inch grinding plates. Type C is designed 
for grinding small grain only, such as wheat, barley, oats, shelled corn, etc., and those wishing 
a high speed mill that will grind small grain very rapidly will find this type especially efficient. 
This type of mill is built in one size only with 8-inch grinding plates. 

Capacity of International Feed Grinder 

The capacity of the International feed grinder varies according to the condition of the 
grain, fineness to which the grain is reduced, the speed at which the grinder is run, and the 
amount of power used. It is difficult to make a definite statement regarding the capacity of 
the grinder, as these four factors vary so greatly. The following table indicates the capacity 
of the grinder for different grains, when the machine is operated at maximum speed with a 
proportinate horse power gasoline engine, and the grain is in average condition:

The table below indicates the speed of the International feed grinder when operated 
with an I H C gasoline engine equipped with regular pulley from 4 to 20-horse power. In 
order to secure the greatest capacity with these grinders, they should be operated at maximum 
speed. This will permit feeding the grinder to its fullest capacity. The minimum speed 
for the 8 and 10-inch grinders is 300 revolutions per minute, and the maximum speed, when 
the fly wheel is used, is 600 revolutions per minute. When run at a speed above 600 revo- 
lutions the fly wheel should be removed.

FEED 
GRINDER 



0l^^ 



This grinder has sufficient capacity for the needs of the average farmer. It can be 
driven with from 4 to 10-horse power, the capacity of the mill being determined by the amount 
of power used, the speed at which the mill is run, the condition of the corn, and the fineness 
of grinding. This style of mill will run at about 75 revolutions per minute for each horse 
power, and do satisfac- 
tory work, but to secure 
the best results the mill 
should attain a speed of 
not less than 300 revo- 
lutions per minute. The 
speed can be increased 
to 600 revolutions with 
perfect safety. 

When grinding dry 
corn on the cob with a 
4-horse power engine, 
the speed should be 
about 300 revolutions 
per minute, at which 
speed the capacity will 
be from ten to fifteen 
bushels per hour; where- 
as, if an 8-horse power 
engine were used, the 
speed would be about 
600 revolutions per min- 
ute, and from 30 to 36 
bushels could easily be 
ground. , .^__ , ^ ,

International 10-Inch Feed Grinder 



I; 



TYPE B 

In construction the 10-inch feed grinder is very similar to the 8-inch grinder. The 
frame and hopper, however, are 8 inches longer and the main shaft has a larger diameter. 
This grinder has proved to be exceptionally popular with dairymen, stockmen, and feed-store 
men, where a large size grinder is required. Six to 15-horse power may be used to operate this 

grinder. When corn is 
dry and in good condi- 
tion, this grinder run- 
ning at a speed of from 
33 to 40 revolutions per 
minute, for each horse 
power, will grind from 
13 to 60 bushels of ear 
corn per hour. 

In breaking and grind- 
ing corn on the cob, 330 
to 300 revolutions per 
minute generally gives 
the best results. When 
a larger engine is used 
this feed grinder can be 
run up to 700 revolu- 
tions per minute. As a 
precaution, however, the 
fly wheel should be 
taken off whenever the 
speed goes over 600 revo- 
lutions per minute.

Large Steel Hopper 



The hopper is exceptionally large and is made of sheet steel. The inside of the hopper 
is perfectly smooth. There are no projections to obstruct the grain. It is reinforced at the 
top to prevent it from being bent out of shape.

Breakers 

The breakers which mash up the cobs and also act as a force feed in working the grain 
toward the grinding plates, are all located on the steel shaft as is shown in the illustrations 
below. The points of these breakers are chilled which insures lasting qualities. The chilled 
concave is placed just below the breakers, being fastened to both sides of the frame with 
wooden pins. This construction ehminates the possibiUty of springing the main shaft and 
breaking the grinder should a stone or a piece of iron get into the hopper, as the wooden pins 
will snap before the grinder is damaged. The flow of grain into the grinding plates is regulated

by means of a shut-off 
which is operated by a 
small lever just above

This shut-off leaves nothing to wish 
for as not a particle of grain is admit- 
ted into the grinding plates when it 
is closed.

Spring Tension 




The grinding plates are held in position by a heavy spring which 
minimizes the danger of breakage of the plates should a hard foreign sub- 
stance get into the grain. The grinding plates are held apart by a shoulder 
on the tension rod which prevents the spring from forcing them together 
when there is no grain in the mill. Breakage is further guarded against 
by a very convenient lever located at the end of the shaft. By means of 
this lever, it is possible to separate the plates without changing the ad- 
justment. 

Grinder Parts 

The crushing and grinding parts of the International feed grinder are 
driven by the heavy steel shaft which extends through the grinder. This 
shaft runs in extra long anti-friction Babbitt bearings. The stationary grind- 
ing plate is bolted to the frame of the mill, while the running plate is attach- 
ed to the shaft, and is self-aligning. This self-alignment is secured by means 
of a ball-and-socket connection which permits the running plate to align 
itself at all times to the one on the frame. This construction, among other 
great advantages, insures an even running mill and evenly ground feed. 
The cross section illustration on this page shows the construction of the 
ball-and-socket connection. 

The end thrust of the shaft is taken up by a ball bearing. 



Grinding 
Plates 

This type grinder is 
regularly equipped with 
one pair of medium 
grinding plates and one 
pair of fine grinding 
plates. At a shght ad- 
ditional cost, one pair 
of coarse or extra fine 
grinding plates can be 
secured.

i 

i 




Sacking Elevator 



The chief feature of this elevator is a divided spout to which two sacks can be attached 
at the same time ; while one sack is being filled, the other may be removed and another 
quickly adjusted in its place. This is a very convenient elevator for putting ground feed into 
sacks. It is well made, efficient, and can be attached either to the right or left of the grinder. 
Both sacking and wagon elevators can be readily attached to the Types B, 8-inch and 
10-inch mill or Type C. The wagon elevator is shown on the following page. 

Extras 

A large, heavy fly wheel is furnished with the International feed grinder as an extra 
at a slight additional expense. Special breakers, shown on page 5, to take the place of the 
regular breaker, will also be furnished at a nominal cost.

Wagon Elevator Attachment 



Any fariiier who uses a wagon elevator attachment will testify as to its time and labor- 
saving properties. When ground feed is to be placed in a wagon, or bin, this elevator delivers it 
direct without handling. It is made of well-seasoned lumber and is very strongly put together. 
The conveyor, should it become slack, can be tightened very easily by means of adjustable 
tighteners with which the upper shaft is provided. 





Wagon Elevator Attachment 

The illustration shows the elevator equipped with a wagon spout and a sacking attachment 
which are interchangeable on this elevator. The wagon spout works on a swivel and can be 
adjusted to deliver the ground feed in any desired direction. It can also be removed very 
easily when the sacking attachment is to be used. The wagon spout is shipped regularly with 
the wagon elevator. If a sacking attachment, which can be secured at a slight additional 
expense, is desired in place of the wagon spout, it should be so stated when ordering.

International 8-inch Small Grain Grinder 

TYPE C 



Farmers wishing to grind small grain, such as wheat, oats, barley, shelled corn, etc., will 
find that the Type C small grain grinder will supply this want. It was especially designed 
to grind satisfactorily all such small grains. It is built along the same lines as the Inter- 
national Type B feed grinder described on the preceding pages, with the exception that the 
arrangement of the hop- 
per is entirely different. 
In place of the breakers 
on the regular feed 
grinder, this hopper has 
a bottom that is incUned 
toward the grinding 
plates. This bottom is 
securely riveted to the 
sides of the hopper and 
directs the grain into a 
worm feed which forces 
it into the grinding plates. 

Where a mill iswant- 
ed that will grind small 
grain in large quantities, 
this mill will be found 
eminently desirable. The 
speed at which this mill 
is run and the amount of 
power used determines 
its capacity. Each horse 
power will develop 175 
revolutions per minute 
and the mill should be 
run at a speed of from 
800 to 1,500 revolutions 
per minute. 

A very superior feat- 
ure of this feed mill is its 
adjustable shut-off. By means of this shut-off, the feed may be closed down or regulated 
so that it can be operated with as low as 4-horse power. The amount of grain, the horse 
power used, and the speed, determine the capacity. Of ordinary small grain, this mill 
will grind from 1 to 50 bushels per hour. With 1 ,200 revolutions per minute and a 6-horse power 
engine 25 to 35 bushels of oats per hour can be ground. This mill does not require a fly-wheel.

Worm Feed 



The International Small Grain Grinder has a worm 
feed which forces the grain into the grinding plates very 
rapidly. The speed may range anywhere from 800 to 1,500 
revolutions per minute. To grind a large quantity of grain, 
it is essential that this mill be operated at a high rate 
of speed. The worm feed is a great advantage and is 
a very efficient factor in regulating the amount of grain 
going into the grinders, thus preventing over-loading. 

In the illustration on this page the hopper and 
grinding plates are removed from the mill to show the 
construction of this worm feed. 



Rate of Feed 



The amount of grain which is fed into the grinding 
plates is regulated by an adjustable shut-off located in the 
hopper just over the worm feed. This shut-off is so 
arranged that the mill can be operated not only with a 
4-horse power engine, but equally well with an 8 or 10- 
horse power engine. 

The shut-off, which has proved itself in every way 
satisfactory, has been no small aid in making the Inter- 
national small grain grinder popular.

only the desired amount of grain to be 
fed into the grinding plates. It can be 
adjusted according to the amount of 
power. When this shut-off is closed, 
no grain can get into the grinding 
plates.

Ground i't-ed Not Only Makes Fine Beef but Also Increases the Milk YiL^ld 

Advantages of Ground Feed 

Prof. W. J Kennedy of the Iowa State College, in an article in the Farmer's Tribune on 
the subject of grinding feed for live stock, says: 

"A careful study of the experiments conducted by the various experiment stations 
under a variety of conditions and with different classes of stock, has invariably shown that it 
requires less ground grain to produce a given amount of milk, meat, or work than it does when 
whole or unground grain is used. In some instances the difference is very wide— as high as 
35 per cent being saved by grinding, while in other instances the difference is not very marked. 
Averaging up the results of all the tests reported, we find that there is a saving of about 12 
per cent effected by grinding feed for the various classes of animals. 

" The above calculations are based on simply the cost of grinding and the feed saved 
by doing so. They do not take into consideration the influence which ground feed may have 
on the animal. In some instances where animals are out of condition or are teething, it may 
be almost necessary to feed ground feed regardless of the price of feed stuffs or of grinding the 
grain. Cases of this kind must always be considered. So far we have treated the matter in 
a general way. We will now discuss it in a different way, treating each of the various classes 
of stock independently of the others. For horses at real hard work, and especially if they are 
worked long hours, all the grain should be ground and mixed with chopped hay. By so doing 
you will save the horse a lot of time and energy, both of which are important considerations 
in the case of the hard-worked horse. Old horses with poor teeth should always be fed on 
ground grain, as it is impossible for them to make good use of whole grain. Colts, during the 
spring months, or at any other season of the year when they are shedding their teeth, should 
have ground grain, so as to prevent any unnecessary use of the jaws during such a period.

Ground Feed Produces Fine Pork

"When it comes to the cattle-feeding business, several factors must be considered. The 
grinding of grain is generally done for the purpose of aiding digestion, thus causing less waste 
of the grain fed. Where hogs are used as followers in the cattle-feeding business, there is not 
much chance for waste in this connection. What the cattle fail to utilize, the hogs clean up, 
so that the two together make a very good combination. These methods of feeding became 
almost a universal practice during the times of low-priced feed stuffs and scarcity of labor. 
In those days everything was done with but one object in view, which was to save labor. 
Corn was scooped into feed troughs and the animals ate what they wanted, and the rest was 
thrown out to be eaten by the hogs or tramped in the mud, depending on the condition of the 
feed lot. 

"Things have changed during the past few years. When feed stuffs are high in price 
and hogs are not available to follow the cattle, all feed should be ground. For a quick finish 
and good results in the feed lot, the following method of feeding is quite often adopted, and 
usually with good results: 

"The cattle are started on snap corn, on which they are fed about four weeks. They 
are then fed on shelled corn, crushed corn, or corn and cob meal for about six weeks. From 
this time on they are fed on corn meal and some supplementary feed, such as oil meal, gluten 
feed, cottonseed meal, or dried blood. Such a method would always involve the grinding of 
feed. Corn and cob meal has given very good results, and in feeding experiments has given 
equally as good results, pound for pound, as corn meal. It is shown that corn and cob meal 
gave the best daily gain in both cases. In one instance less corn and cob meal was required 
for a given gain, while in the other, more was required. The average of the two trials shows 
that a pound of corn and cob meal is equal to a pound of pure corn meal in steer feeding. In 
explanation of the marked difference in the amount of feed required for a given gain in two 
trials, we have the following statement concerning the cattle: 'The first lot of steers were a 
thin, half-grown lot of "natives," while the second lot were high-grade short-horns, mature and 
full-fleshed at the start.' The second lot was also fed for a longer period.

"For dairy cows giving a large flow of milit, all kinds of grain should 
be ground. Corn and cob meal, when fed with oil meal or gluten feed, is pre- 
ferable to corn meal. Corn and cob meal is a more bulky food than corn 
msal, thus better adapted to the needs of the cow from a digestive standpoint. Animals under 
one year of age can make as good use of whole fe.ain as they can of ground feed, thus there is 
no need of going to the expense and trouble of grinding feed for them. Breeding stock usually 
makes better use of corn and other grain when ground, except in the case of corn when it is 
fed in the snapped form. 

"A large number of experiments have been conducted for the purpose of determining 
the value of grinding grain for swine, and on averaging all the results it has been found that 
the grinding of the various kinds of grain effects a saving of about eight per cent of the grain 
fed." 

Experiments that have been conducted prove and authorities agree that cows give 
more milk and horses are capable of more work when their feed is ground; cattle, hogs and 
sheep can be fattened more rapidly with ground feed than with whole grain. Feeding whole 
grain is very expensive, and it is a profitable investment to have a feed grinder on the

The following is an analysis of corn and cobs under the signature of H. E. Wiley, 
United States Agricultural Chemist, at Washington, D. C. 

Cobs Kernels 

Water 9-33 per cent 10.49 per cent 

Ash 1-33 per cent 1.55 per cent 

Oil 47 per cent 5.49 per cent 

Carbohydrates 56.01 per cent 67.72 per cent 

Crude Fibre 30.36 per cent 2.13 per cent 

Albuminoids 2.50 per cent 10.62 per cent 

The analysis shows that corn cobs are of value, and should be utilized in connection 
with the kernels grown upon them.

Ever Ready Power 







I H C Horizontal Gasoline Engine 
4, 6. 8, 10, 12, 15, 20 and 25-Horse Power 



The gasoline engine is the real prac- 
tical power producer on the modern farm. 

Gasoline power can be applied not only 

in the field but also to the smaller jobs 

around the house, tool house, and barn. 

It will furnish convenient power for op- 
erating the feed grinder, and is especially 

adaptable for this purpose on account of 

the variation in the power required in 

proportion to the kind of grain being 

ground. No matter how much power 

the feed grinder needs to do its work 

properly, the I H C gasoline engine will 

easily handle the grain — and at so small 

an expense that the amount will hardly be noticed. 

The engine can be started simply by closing the switch, opening the fuel valve, and giving 

the fly wheel a turn or two. A child can start it, but it does not even require a child to watch 

it when once started. It 
works steadily until the 
fuel is gone. 

The I H C Line 
Includes 

I H C Vertical engines — 
made in 2, 3, 25, and 35- 

horse power. 

Horizontal (Portable and 
Stationary) in 4, 6, 8, 10, 
12, 15, 20, and 25-horse 
power. 

Famous air cooled en- 
gines — in 1, 2, and 3- 
horse power. 

I H C Gasoline tractors 
in various styles and 

sizes. 

Pumping, spraying, and 
sawing outfits.
