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
Grinders are given in

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:
Mixed erain, corn and
8 to 35 Bu.
15 to 50 Bu.
15 to 35 Bu.
20 to 50 Bu.
12 to 25 Bu.
20 to 40 Bu.
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.

International 8-Inch Feed Grinder
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
When grinding dry
corn on the cob with a
4-horse power engine,
the speed should be

speed the capacity will
be from ten to fifteen

as, if an 8-horse power
engine were used, the
speed would be about
600 revolutions per min-

International 10-Inch Feed Grinder
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.

the Working Parts of the Grinder
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

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.

Sacking Elevator Attached tO the
10-Inch Feed Grinder
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.
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
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
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.

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.

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
"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
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
farm where it is ready for use when desired.
It Pays to Grind Corn Cobs
The following is an analysis of corn and cobs under the signature of H. E. Wiley,
United States Agricultural Chemist, at Washington, D. C.
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.

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.
