The imperative demand for a motor possessing the elements of safety, economy, simplicity and durability, has called forth, dur- ing the past century, the best efforts of the most eminent engi- neers both of Europe and America, as evinced by the many varieties of motors at present in existence, operated by gas, atmospheric air, carbonic acid, ammonia, electricity, etc. ; but, till very recently, steam has been pre-eminent in utility, notwith- standing its danger, high rate of maintenance, and total unfitness in the hands of inexperienced persons. A careful examination of all the motors mentioned above, shows that atmospheric air is the only agent at all likely to successfully compete with steam, from its universal presence, its low capacity lor heat, and its capability of producing great power when properly applied ; and in this proper application consists the superiority of the RIDER COMPRESSION ENGINE. Aa its name implies, the chief and distinguishing feature of this Engine is, the nse of highly compressed cold air, the thorough heating thereof , without change of volume, and its efficient expansion to a point to or below the pressure of the atmosphere, thereby completely utilizing all the force or mechanical effect po8iible. k , 4 THE RIDER COMPRESSION ENGINE. All these changes are consecutively and rapidly effected in this motor, without the use of valves, springs, levers, or, in fact, any delicate parts whatever, the moving parts being reduced to the lowest possible number, viz: the pistons, shaft, and connections. ADVANTAGES POSSESSED BY THE OVER ALL OTHER MOTORS. 1. — Its perfect safety under all circumstances and conditions. Unlike a Steam Engine, no explosion is possible. Unlike a Caloric Engine, it emits no heated air or sparks of carbonized oil, as all the air is continuously retained within the Engine, and cooled down below the temperature of the surrounding atmos- phere, at each revolution, thus making the Engine even safer THAN AN ORDINARY STOVE. 2. — Its Extreme Simplicity. It has not a Valve, Spring, Cam, Eccentric, or any loose or delicate part about it to get out of order. 3. — Its Great Economy. Twenty to thirty pounds of coal being sufficient to run a one-horse power Engine ten hours. 4. — It is Perfectly Noibeless. 5. — Having no valves, there is no exhaust or escape of burned oil, or any noxious odor. 6. — iTjtEQUiREs no Engineer, and little skill to operate it, as it has no boiler and uses no steam, and only requires that the tire be occasionally replenished and bearings oiled. 7. — It does not Increase Risk of Fire or Cost of Insurance. 8. — It requires less space and less fuel than any other motor of equal power, % THK HIDKR COMPRESSION ENOINE. can be nsed in umuy places where Steam and Calorio Kugines would be inadmissible on account of danger or noise. 10.— The tire can at any time be replenished and inspected without ■topping the Engine. 11. — Even.- part of the Engine, both internal as well as exter- nal, can be reached and examined without the least difficulty. 19. — Tbe Compression Engine PBODUOJta more than double TBE AMOUNT OF POWER WITH A GIVEN WEIGHT OF FUEL THAN HAS EVER BEFORE BEEN REALIZED IN ANY OTHER SMALL MOTOR; and this can be demonstrated to the perfect satisfaction of all who may examine it. The different sizes of our Compression Engines are adapted to the use of Printers, Lithographers, Ice Cream Manufacturers, Sausage Makers, Bakers, Founders, Machinists, Light Hardware and Jewelry Manufacturers, Locksmiths, &c, for Hoisting, Churning, Milling, Sawing Wood, Driving Farm and "Wood-work- in-.,' Machinery, Shoe Machinery, Coffee and Spice Mills, Blow- ing Organs, Arc. The work, however, for which these Engines are specially adapted, is For this purpose we can justly say they are the most perfect engines ever constructed. Their marvelous simplicity, absolute safety, great economy, and wonderful effectiveness rendering them far superior to any other Pumping Engine in the market. Each Pumping Engine is furnished with the Rider Patent Rol- ling-Valve Pump — double acting — which works at any speed without the slightest shock or noise. The PumpTs placed on the side of the cooler, and works directly from the compression piston (as may be seen by reference to the cut), thus insuring perfect rectilinear motion; and all the water is passed directly from the pump through the cooler on its way to the tank or out- let, making the most complete arrangement possible. b THE BIDEK COMPRESSION ENGINE. CAPACITY. The Six-inch, or Household size, will very easily deliver nine hundred gallons of water per hour, at an elevation of sixty or seventy feet from the surface of phe well or cistern; or a pro- portionate quantity at a greater elevation; and will use, when running ten consecutive hours, from twenty to thirty pounds of coal only, requiring scarcely anymore attention than an ordinary stove. This size is particularly adapted for supplying city and suburban residences, stores, tenement houses, hotels, boarding houses, &c, with water, as the expense of furnishing an abun- dant supply is thus reduced to an unprecedentedly low figure, being really only from one to two cents for a thousand gallons. These Engines are also well adapted for nurseries, breweries, tanneries, supplying fountains, irrigating lands, pamping water for cattle, furnishing water for hydraulic elevators, &c. The next larger size, viz , the ten-inch Engine, we can confi- dently recommend as The Great Railroad Pumping Engine of the Age. For this purpose, i. e., supplying railroad water-stations, and other places where considerable water is required, it stands alone, ' UNRIVALED AND PRE-EMINENT. DESCRIPTION AND OPERATION OF THE RIDER COMPRESSION ENGINE As may be seen by the sectional cut on the seventh page, the Eider Compression Engine consists essentially of a compression cylinder A, and a power cylinder B, with their respective pistons C D, and connections, and a regenerator S. The lower portion of the compression cylinder A is kept cold by a current of water which circulates through the cooler E, which surrounds the lower portion of the cylinder, while the lower portion of the power cylinder is kept hot by the action of the fire below the heater F. The heating, and also the cooling of the air, is instantaneoiisly effected by its alternate presentation to the surfaces of the heater and cooler, in a thin annular sheet, such being found by exper- ience to be the only correct method of rapidly and thoroughly effecting changes of temperature in air. This is accomplished as follows : — The compression piston G extends downwards to the base of the Engine, and is a trifle smaller than the interior of the cooler F, thus leaving a thin space on all sides for the air to pass down- ward and become thoroughly cooled on its way to the bottom, and through which space it flows on its way back to the heater. The power piston D likewise extends downwards into the heater F, which in shape resembles the bottom of a champagne bottle, that is, rising in the center, and presenting to the action of the fire, a narrow annulus all around the bottom. "Within this heater is the telescope G t which is a thin iron cylinder, about one-fourth TBS BIPCB COMTRESSION BNOIXX. 9 of an inch leas in diameter than the interior of the heater. It ia fitted to the interior of the power cylinder B, and extends ' nearly to the bottom of the heater. Its office is to cause the air which flows from the .-omprtssion cylinder to be presented in a thin sheet all around the interior surface of the heater, and particularly li the lower and hotter portion. By this means the air is thoroughly and rapidly heated. The same air is used continuously, as there is neither influx nor escape, the air being merely shifted from one cylinder to the other. Between the compression and power cylinders is situated the regenerator //, the economical value of which cannot be over- rated. This regenerator is composed of a number of thin plates slightly thickened at their edges, which, while affording a free passage to the air, subdivides it into thin sheets. It is so placed between the cylinders as to be traversed by the air in its passage each way between the hot and cold cylinders. Thus the heat is alternately abstracted from and returned to the air in its pas- sage backwards and forwards through these plates, imparting great economy and steadiness of power to the engine. The other portions of the engine are readily understood on inspection of the cut. The two pistons are attached directly to to the crank J /, (which stand at an angle of about 95 degrees from each other, the crank of the power piston being in advance, ) by simple connecting rods J J ; and all the movements of the various parts are uniform, being solely derived from reg- ular, circular and rectilinear motion ; and as there are no com- plicated parts, and none of the irregular intermittent impulses which characterize Caloric Engines, a high rate of speed and smooth action may be safely and easily obtained. K K are the packings which are in duplicate for each cylinder. The lower one has its lap downwards to resist the escape of air below the piston, while the upper one has its lap upwards to prevent the lubricating material from entering too freely into the cylinders. Between them is the Belief King, which is so constructed as to almost entirely relieve the friction of the packings. 10 THE EIDER COMPBESSION ENGINE. Z is a simple check valve which supplies any slight leakage of air which may occur. It is generally placed at the back of the engine, at the lower part of the compression cylinder, but is nec- essarily shown in the sectional cut on the side. OPERATION s The operation of the engine is "briefly as follows : — The compression piston C first compresses the cold air in the lower part of the compression cylinder A into about one-third its normal volume, when, by the advancing, or upward motion of the power piston D, and the completion of the down-stroke of the compression piston C, the air is transferred, from the compression cylinder A, through the regenerator H, and into the heater F, without appreciable change of volume. The result is a great increase of pressure, corresponding to the increase of temperature, and this impels the power piston up to the end of its stroke. The pressure still remaining in the power cylinder and re-acting on the compression piston C, forces the latter upward till it reaches nearly to the top of itB stroke, when, by the cooling of the charge of air, the pressure falls to its mini- mum, the power piston descends, and the compression again begins. In the meantime the heated air, in passing through the regenerator has left the greater portion of its heat in the regen- erator plates, to be picked up and utilized on the return of the . air towards the heater. Heatek. The heater is made by a peculiar process of our own, whereby the metal is rendered very dense, and refractory to the action of heat, thus greatly increasing its durability. Packings. The packings are simple discs of leather, and will last a very long time without renewal : those on the hot cylin- der are kept cool by a small stream of water, which circulates round the upper portion of the cylinder, so that there \i no dan- ger of o v ©rheating them. Connecting bodb. The Connecting rods are of the best known TBI BXDSft OOKPRKaetON BNUINK. 11 construction. Their ends are made of gun metal, connected to- gether by a tube, in which is fitted a rod, extending from the up- per to the lower brass, and so arranged that one key, capable of nice adjustment by nuts, at once takes up the lost motion on both upper and lower brasses. This tube also permits the oil to flow down to the lower brass, and thus Wi etuis are lubricated from the oil cup at the same time. It will be seen that this construction is at once efficient and durable ; no loose straps, gibs or other pieces are used, and there is no chance of consequent breakage. Watbb. As before stated, in the Pumping Engines the whole of the water pumped is passed directly from the pump through the cooler, thus effectually and instantaneously cooling the heat- ed air, which passes down the interior of the cooler on its way to the b'lttom. Avery small pump is also furnished with the Power Engines, which is attached like the large pump of the Pumping Engine, to the side of the cooler, and a small stream of water is injected with each stroke of the piston. This may be returned, if desired, to the barrel or reservoir from whence it ia taken, until the water becomes in time too warm for effective use; or, it may be allowed to run to waste, which is preferable where water is not too scarce, as the cooler the compression cylinder is kept, the better. Where a pressure of water can be obtained, the small pump may be disconnected if desirable, and a very small stream allowed to flow into the cooler, and pass out at the opposite side. No pains are spared to make these Engines perfect in every respect. The materials and workmanship are of the best qual- ity, and we are confident that the public will find them unequaled for compactness, design, efficiency, and general usefulness. 12 THE BIDEB COMPRESSION ENGINE.

We insert a few letters from gentlemen, who have the Eider Compression Engines, to show the appreciation in which they are held : — Sam Jose, June 24th, 1876. Messes. Huntington, Hopkins & Co., Gentlemen : I take pleasure in saying that the Rider Com- pression Engine and Pump which I bought of you has given entire satisfaction, doing all you. claimed it would. / consider it a grand success. Yours truly, T. ELLAED BEANS, President Bank of San Jose . San Francisco, July 7th, 1876. Messes. Huntington, Hopkins & Co., Gentlemen : The ten-inch Eider Engine and Pump purchased of you has now been in use two months, doing all you claimed for it, and giving entire satisfaction — pumping 4000 gallons of water per hour, and consuming one-fourth the amount of coal used by the steam pump doing same amount of work.

THK ftXDKR COMPRESSION KNOINE. 13 San Jose, July 8th, 1876. ffmRnoTon, Hopkins & Co., Utmiltmen : The six-inch Rider Compression Engine and Pump whuh I have had in use about two mouths, is nil, in fact I it to be, and gives entire satisfaction, 1 attention ami a very small amount of coal for mad. Pomping 5000 gallons at an expense of Yours truly, W. D. TISDALE. San Francisco, July 31st, 1876. HtTNTINOTON, HOPKINS & Co., The Rider Compression Engine which you furnished me has now been in operation nearly two months, and is working well. It runs one Taylor Cylinder and four Gordon Presses easily, with power yet to spare. For purposes requiring from one to three-horse power, I believe the Rider Compression Engine is without an equal, M it is simple in construction and does not require the services of an engineer ; no extra rate of insurance is exacted; and it requires but little more fuel to generate the necessary power than I use in my stove during the winter season. For my pur- poses, it cannot be equaled by anything within my knowledge. Very Respectfully, C. W. GORDON, 32G Sansome St., San Francisco. 559 Lexington Ave., N. Y., May 5th, 1876. The Rider Pumper (Household size) you set up in my apart- ment bouses, "The Lexington," on 49th street, last year, has proved itself in all respects better than you claimed. You guar- anteed it to me to pump 800 gallons water an hour, but on a test it pumped 1260 gallons. It has never had one cent for repairs put on it, and is in as good order as when new. To pump for the five houses it has to work a half hour morning and night. For pumping I think it has no superior, and shall probably put one in my houses in 50th street. Yours, J. C. DONNELLY. 14 TEE EIDEK COMPRESSION ENGINE. New Yobk, December 6th, 1875. Enclosed please find cheek in payment for the Household Pumping Engine purchased of you some two months since. I am perfectly satisfied with it in every respect, and can pump from the cellar of my French flat houses to the roof (five floors), eight hundred gallons of water per hour, at a merely nominal cost of running. The Engine can be seen any day in my houses, corner of 91st street and 3d Avenue. Yours, &c, EOBEET G. GEEGG, No. 1 Bowery. Manhattan College, I New Yobk Cut, March 17th, 1876.' f The Eider gives entire satisfaction ; we did not anticipate it would work so well or prove so useful ; you may Bend parties desiring to purchase to the Institute, to see how it works. Yours Truly, BEO. PAULIAN. Office of Palmeb, Embuby & Co., ) 46 Elizabeth Street, } New Yobk, Dec. 15th, 1875.) The six-inch Compression Pumping Engine which you sent me for my house in Orange, N. J., is all that you represented it to be. The cost of running it is comparatively nothing — about two quarts of coal (nut size) will fill my tank, which holds about one thousand gallons, drawing the water from either well or cis- tern, and elevating it to the tank, 30 feet. The steam engine which I first had for the same purpose cost so much for fuel and to keep in order, that I could not afford to run it. It was a con- stant source of fear that it might blow up ; consequently I did not dare to leave it while steam was at a pressure in the boiler. Your engine pumps the tank full while I am eating my supper, and requires no more attention after it is properly oiled and started than the kitchen fire. My servant (cook), makes the fire in the engine before I return home from business, so that all I have to do is to oil and start it. She can run it as well as I can, but I generally do it for my own amusement. My architect, Mr. J. Frank Lyman, of Orange, N. J., says you may refer to him.. Youtb Eespectfully, PETEE A. EMBUEY, thi »n>K» coxrmnnov exodii. 15 Xkw Yom, December 2d, 1875. Enclosed please And check in payment for the one-horse Com- pression Engine bought of you last month. I »m well satisfied with it, and tiud it does my work perfectly. I rnn a 2i-incb grindBtone and 10-inch emeiy wheel, to do light grinding in my hardware store. I would recommend it to any desiring a motor of small power as being juM the tiling. My son, <. is the only engineer it requires, and it causes me no anxiety. Yours truly, M. SCHONBOKN, 510 Greenwich St. Nsw York, February 10th, 1876. The Household Kider Engine I bought of you several months since, has proved itself fully as good as you guaranteed it, as regards economy, simplicity and power. It runs two barrels of gum and alcohol, and one small mill for grinding gum. It does this with perfect ease, thUB doing away with the expense and annoyance of having boys to do the work now done by the engine, requiring little or no attention, only enough to keep up a small fire ; for parties desiring small power, I should recom- mend the Household Engine as being the best small motor I ever saw, and as being the extreme of simplicity. Yours, &c, C. P. WILLIAMS, 48 Crosby Street. The Eider Compression Engine is destined to create a revolu- tion in machinery.
