Letters Patent No. 111,530,-dated February'7, 1871.

.IMPROVEMENT IN IFEED-GRINDERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may cbncern Be it known that -I,-MYRON GORE, of Ottawa, in

the county of La Salle and in the State of Illinois, have invented certain-new and useful Improvements in FeedGrindcrs; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawing and to the letters ofreference marked thereon making a part of this specification.

The-nature. of my invention consists in the con,- structionand arrangement of a feed-grinder, as will be hereinafter fully set forth.

In order to enable others skillediu the art to which my invention appertains to make and use the same, I will now proceed to describe its. construction and operation, referringto the annexed drawing, in which' Figure 1 is a plan view of my machine, part of the samebeingiin horizontal section;

.ring D is secured by bolts and nuts 01' other suitable means, leaving a convenient space between the head 0 and said running ring. I

In suitable hearings, on the frame A, is also placed an arbor, E, on a line with the shaft B. I Y On the inner end of this arbor is attached the head G, to whichthe ring His bolted or otherwise secured.

This head and ring are so arranged as to be within the arms a a of the head 0, and between said head and the ring D.

I is the hopper, to which is bolted or otherwise se-' -cured, another ring, H, which faces the opposit side of the revglving ring D. r

The hopper L'is' provided near its lower end with a huh, I), whichis' nicely fitted to the shaft or arbor A pin, d, passes through said hub and a horizontal slot in the arbor, preventing the hopper, with its ring, from turning on the arbor, but allowing it to slide back and fortlPfor a short distance.

The pin (1 also passes through the forked end of an arm, J, the other end of which is pivoted to a lever, K, said lever beingpivoted inthe'frame A;

. To the lever K is also pivoted another arm, J, which, by a pin, is connected with the arbor or shaft E.

The points where the arms J J are pivoted to the lever K should be one on each side/and the same distance from the pointiwhere the leveritself is-piv-- oted. g

It will be seen that the ring D revolves between the rings H H, and remains in the same place con-' stantly,while the rings H H, although not revolving, whence I have called them stationary, are movable to or from the revolving ring D. g

The motion-of these two rings, by means of the arrangement ofthe lever K and arms J J, issnch that they will alwaysbe thesame distance from the center or revolving ring D,whether such distance be large or small.

The entire grinding mechanism is inclosed in a casing, L, of which the hopper I forms a part, and

said casing provided with a suitable outlet-spout.

The'stationary rings H H" are dressed with circular grooves e e and curvedribsf], as shown in fig. 3. This dressing is made so shallow that corn or grain cannot get back farenoughto' be'out of the way of theribs on the running ring.

The running ring D, which is cutalikeon both sides, is dressed with'a smooth surface with curved I ribs g and h, alternating of unequal length, as shown grain between the ribs desired.

Both sides of the running ring B being cut'in the same manner they are used at the same time. Having thus fully described my invention,

. What I claim as new, and desire to secure by Letters Patent, is-

1. The running riugD cut alike on both sides, with ribs 9 hon asmooth surface, and the grooves i, "i, substantially as and for the purposes herein set forth.

2. The stationary ring H, (or H',) cut, as described, with circular grooves e e and curved ribbs f an d used in combination with a running ring, substantially as and for-the purposes set forth. v

3. The head 0, securedon the shaft B and provided with arms a a, in combination with the grindingring D, substantially as set'forth...

4. The movable arbor E with head G and ring H,

in combination with the movable hopper I and ring H, all constructed and arranged, as specified, to be operated by means of the lever K and arms J J, or other suitable means, substantially as and. for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 1 4th day of November 1870 MYRON GORE. Witnesses:

O. LnAvnNs, N. K. BROWN.
