IMPROVEMENT IN MACHINE FOR 'CLEANING THE INTESTIN-ES 0I' SLAUGHTERED ANIMALS.

Be it known that I, JOHN A.vTHo'Mrfs'o-N, of the town of Bucyrus, in thecounty of Crawford, and State of Ohio, have invented a new and useful Machine for Cleaning the Intestiuesof Slaughtered Animals, by'drawing them between revolving brushes'; and I do hereby declare that the following is a full, clear, arid exact descriptionof the construction and operation of the same, reference being had to the anneized drawings, making a part of this specification, in whieh- Figure 1 is an inside view of my machine.

, Figure 2 is a view ofthe main or crank-wheel and shaft, with the main cog-wheel at a, and a pinion at I1,- with a wooden roller surrounding it midway, having flanges at each end of said wooden roller, at e c.

Figure 3 isa view of a shaft, with a pinion-at d, working in said crank-wheel at a, iig` 2, and revolving a larger cog-wheel ate, to give direction and velocity to the revolutions of the brushes, hereinafter mentioned.

Figure 4is a view ofthe revolving brushes A A, having each a pinion atff of the shaft, the cogs whereof work in each other, and the upper pinion,f, works in said wheel at e, fig. 3;

Figure 5 is a view of-.a shaft and cog-wheel, revolving the. saine on the end thereof at g, which is slowly turned by the pinion at fig. 2. On the centre of said last-mentioned shaft is an India-rubber covering, at L which revolves with the shaft. v y

Figure 6 is a view of a revolving shaft, having, midway thereon, a ridged or rugous band of wood, at z', fast ened to and revolving with it in con'trct with said India-rubber baud at h, fig. 5. 4 n Figure 7 is a view of aguide and spreader, hooked on the rear end of the box containing the machinery, passing between said revolving brushes, and kept to its position at the forward end, near said rubber and wooden rollers, by two iron stakes set in the bottom ofthe box containing said machinery, and projecting up to the proper height between said revolving brushes and rollers. p

Figure 8 is a hinged partition, of tin or other sheet metal, serving as a guard for said rollers.

To enable others skilled in the art to make and use my invention, I will `proceed to describe its construction and operation.

l use a water-tight box ofthe proper size, say about three feet long, about ten inches wide, and about eight inches deep, and having set the wheels and shafts aforesaid to their proper positions, as shown in the drawing, the guide, g. 7, is unhooked, and out ofthe machine, the intestines are turned inside out in the ordinary mannel", and drawn on the guide, fig. 7. Said guide, with theintestines thereon, is put/toits position aforesaid in the box the crank is first turned backward so the brushes will draw through between theu the end ofthe intesltine; then the pinion at d, iig. 3, which is made to slide on its shaft, is momentarily slid out of geen so the brushes cease for the time to revolve,vthc crank is turned forward, and the endpof the intestine introduced between the rollers at 7L and z', gs. 5 and 6, which thereafter hold it; the pinion is then slid back to its position with' said crank-wheel, fig. 2. The Vcrank is then turned forward. The pinion, iaft, and wheel, iig. 3, turn the upper brush, A, by pinionf, which in its turn revolves the lower brush by means of the pinionf, on the end thereof. The front intestine is carried between said revolving brushes, and having been passed between said rubber and wooden rollers at t and t', figs. 5 and 6, said rollers,.by their revolutions, draw said intestine conA stnntly and regularly forward, pulling the same along between said revolving brushes. The end is taken by the hand of the operator at rst, and passed over said wooden roller on said shaft at c e, iig. 2, pointing forward, and thereafter the intestines are carried over said partition and guard, fig. 8, and delivered in a cleansed state into a separate apartment, and by means of said guardare kept clear from clogging the machinery.

The box is first nearly filled with water, and the rapid revolutions of the brushes AA thoroughly clean the intestines, and deliver them in a suitable condition for sausages, Bolognas, or stuffed puddings.

I construct my brushes as shown, by bolting two fiat or slightlyrounded brushes on each side of said shafts, at A A, fig. 4, in preference-to cylindrical brushes, for the reason that they allow the intestines to pass more freely. The guide and spreader, iig. 7, serves to present a flat surface of the intestines to said brushes, although the machine works wellwvithout said spreader. u

What I claim as myinvention, and desire to secure by Letters Patent, is:-d

i for the purpose set forth.

1. The cleaning'of the intestines of animals by revolving brushes, substantially as herein described. 2. The cleaning of the intestines of animals by machinery, which operates to draw the intestines through between contiguous revolving brushes, by means of contiguous rollers, substantially as herein described.

- 3. The driving-Wheel a, pinion d, grooved or ilanged roller c, gear-wheel e, gun] roller l1., fluted rollers', and brushes A A, when arranged, combined, 4and operateol substantially in the manner herein shown and described,

JOHN A. THOMPSON. Witnesses:
