SPECIFICATION forming part of Letters Patent No. 650,458, dated May 29, 1900.

Application filed February 17, 1899. Serial No. 705,833. (No model.)

To all 2072,0711, it may concern:

Be it known that I, ROYAL P. FARIEs, a citizen of the United States of America, residing at WVichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Grinders for Grain or Fruit, of which the following is a specification, reference being had therein to the accompanying drawings, and the letters and figures of reference thereon, forming a part of this specification, in which- Figure 1 is a side view of myimproved mill for grinding grain or fruit. Fig. 2 is a top plan of the same. Fig. 3 is a vertical section of said mill, and Fig. 4 is a perspective detail of the swinging semicircular grinder.

This invention relates to certain improvements in grinding-mills for grinding grain or fruit; and it consists of the construction and arrangement of parts; and the object of my invention is to produce a mill adapted to grind either grain or fruit, either coarse or fine, inexpensive and durable.

Referring to the drawings, 1 represents the outer casing of the mill.

2 represents a swinging semicircular grinder. 3 represents a shaft on which said swinging grinderis keyed. 4 represents the grind ing-face of said swinging grinder. 5 represents the teeth of said swinging grinder, extending across said grinder, as shown in Figs. 2 and 4, and graduated in size, larger at the top and growing smaller to the bottom, as shown in Figs. 3 and 4. 6 represents the adjustable yielding grinding-face of said mill, made on the same radius as the swinging surface 4. 7 represents said surface diverging from said surface 4 toward the top. 8 represents graduated teeth on said surfaces 6 and 7. 9 represents ribs on either side of said yielding grinding-surfaces 6 and 7. 10 represents a hole near the top of said ribs. resents lugs integral with said ribs 9. 2 represents set-screws passing through said lugs 11 and pressing against the edge of the outer casing 1. 13 represents a bolt which passes through the holes 10 in said ribs and outer casing 1. 14 represents a nut on said bolts.

15 represents arms integral with the lower edge of the outer casing 1. 16 represents a cross-bar secured to the outer end of said arms 15.

11 rep:

adjusting-nut 18. 19 represents a coil-spring with one end pressing against said adj usting- Iiut 18 and the other end yieldingly holding the grinding- teeth 5 and 8 at the proper distance apart for grinding by pressing against the surface 6. 20 represents a pin or lug made integral with said surface 6 for holding said spring in place. 21 represents bolts for securing said cross-bar 16 to the arms 15. 22 represents the smaller lower teeth 5 and 8, separated from the surfaces 4 and 6 and held in place by the bolts 23. Said plates are made separate, so that they may be made hard for grinding and easily replaced when worn out.

The shaft 3, to which the grinder 2 is rigidly secured, is journaled in the boxes 0. in the casing 1.

After some use the bearings become worn, and as the grinding-faces of the swinging and stationary grinding-plates are necessarily in 17 represents an adjusting-bolt having the i close proximity the swinging grinder would when the mill is running empty move over in the direction of the stationary grinder, and the teeth of the opposing faces of said grinders come into contact with each other. If this occurs when the mill is running, the teeth would of course be broken off. To avoid this, a spring-plate 24 is provided located to the rear of the shaft 3, having its end turned inwardly and bearing on the boxes a.. On the central part of the shaft 3 a sleeve 25 is secured,from one side of which a threaded shank 26 extends, which projects through the plate 24 and receives on its end a nut 27. This nut finds a bearing against the plate 24 and tends when screwed up to draw the shaft 3 and spring together, this action flexing the spring. If the bearings of the shaft 3 Wear, the spring will hold the shaft at the rear of its bearings in the box a and prevent the grinding-faces coming into contact with each other. 28 represents the upper part of said mill-flanging to receive the wooden hopper 29, the back part 30 of said hopper reaching down into the throat of said mill.

31 represents a hub keyed to the outer end of the shaft 3. Said hub is provided with the arms 32 and 33, the arm 33 having the holes 34 for adj ustably securing a mindmill or other motive power to said mill. The arm 32 is provided with the flanges 35 for holding a han dle by which said mill may be operated by hand. 36 represents a rib along each side of said mill. 37 represents a support on which said mill rests through the medium of said ribs 36 and is held secure by the bolts 38. The grinding-teeth of this mill have their radial surface on the under side and the beveled.

surface on the upper side.

The lower portion of the swinging or oscillating and yielding grinding-surfaces are the same radius, while the upper part diverges toward the top.

This mill is operated in the following manner: The grinding-surfaces can be adjusted.

to grind either coarse or fine through the medium of the set- screws 12 and 17, the grind- .ing-platesG and 7 swinging on the bolt 13.

Whensaid adjustment is made, the mill is fed't'hrough the hopper 29, and the feed is controlled by the slide 30. The oscillating grinding semicircle is started in motion by attaching a windmill or other suitable power to the arm 32 or 33. When said grinder is swinging upward, the teeth 8 will catch and hold the grain from moving upward, and when swinging downward the teeth 5 will carry the grain down into the narrower portion of said throat, thus grinding the grain as it passes through the mill.

Having thus described my inventiomwhat I claim as new and useful, and desire to se cure by Letters Patent, is as follows:

In a grinding apparatus, a casing, a pivoted plate carried thereby, having a grinding-surface,a toothed segment, a shaft carrying the same, bearings in said casing for said shaft,
