'"'•^F'" k "j^jTjnjTjjijjjjr^^ 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.

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: Size Ear corn per hour Shelled corn per hour Mixed erain, corn and oats, etc. per hour 8-inch Plate 10-inch Plate 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.

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 8-lnch Feed Grinder Type B Specifications of the 8-Inch Feed Grinder Power 4 to 10-horse power.

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.

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. Hopper and Grinding Plate Shield Removed to Shov the Working Parts of the Grinder 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.

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. Cross Section Showing Self-alitjning Plate Holder. Self-alignment is Secured l>y Means of Ball and Socket Connection 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 Stationary Plates View Showing Spring Tension and Lever gVtfWgtfg tf^ VWS M.

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.

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.

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.

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.
