MACHINE FOR `SCRAPING ANIMAL CARCASSES.

SPECIFICATION forming part of Letters Patent No. 224,816, dated February 24, 1880.

Application filed October 30, `1879 l To all whom it may concern Be it known that I, STEPHEN` GoLLrNs, of Indianapolis, county of Marion,and State of Indiana, have invented an Improved Machine for Scraping Animal Carcasses, `of which the following is a specification, reference being had to the accompanying drawings. s u

Theobject of my invention is to provide a device that will remove the hair and bristles from the hide of animals.

My invention consists, mainly, in a new inachine for removing hair and bristles from the hide of animals; also, in the new arrangement and constructionof parts and combination of elements `as will be hereinafter fully described in the specification, and set forth in the claims. s Y i In the Iaccompanying drawings, of which there are two sheets, in which like letters of reference in the different figures indicate similar parts, Figure l represents a vertical section, showing theparts between the lines sc .r of Fig. 2. Fig. 2 is a plan view of the machine with thev top removed. Figs. 3 and 4 are vertical sections, same asFig. l, showing the scraper-knives in two diEerent positions;

` and Fig, 5 is a plan view of oneof the Scrapers "fes and its operating mechanism. u

' Referring, now, to the drawings, A repre sents the top of the machine or` one door `of the building in which the machine is operated, and O is the baseof the machine, or the'oor on which the apparatus rests. s u

u To the floor O are attached two or more uprights, N N, to which is permanently secured the inner lower ring, F, of the apparatus.

u The upper inner ring, F, is of the same size tothe topA by hangers c c.

as the lower one, and uis permanentlysecured Around the rin gs' Fand F are secured alarge number of springs, `c'and c3, as shown in Figsl and'2. 'Each set of these 'springs-that is, each spring e and the spring c3, immediately beloware connected together by a series of links, K K3 K5 K7, the upper link, K', being attached to the spring c by the pivot-stud g. The other s joints of the links are pivoted togetherby the pivots h, the joints being formed in the holes m2, Fig.i5, of the levers L, asshown.` u

` Outside of the rings F F. are another set of the lower ring, G', at j5,

rings, G-, below, and `G above. These two rings are united together by bars d, and are provided with springs c above and e? below, with links K K2 K4 K6 arranged and united together and to the levers L in the saine manner as before described. The leversL are pivoted to the outer links ath', and tothe inner links ath, the links being held iu the recesses m and holes m2 of the levers L, as shown.

The rings G G', with their mechanism, as before described, are arranged to move bodily up and down. In order to do this l employ two sets of ropes, cords, or chains, Ic and 7c',

follows, to wit:

One end ofthe rope 7c, Fig. 3, is attached to and extends upwardl through the eyebolt or around a sheave, j', attached to the top A at one side ot1 the machine. lhe rope k then leads to another pulley or eyebolt,j2, thence downward and through the ringj", thence upward to the eyebolt or pulley j2 again, from which it extends to a pulley on the opposite side of the top A from that of the pulley j', and then extends do wnward, and is madefast to the ring G opposite to the fastening f. One end of the other rope, k,is attached to one side of the upper ring, G, at j, passes downward to pulley jg, thence to pulley je, thence up tothe ring jl", thence back to pulley jg, thence to a pulley opposite jf', thence upward, and is secured to the ring G at the opposite side from that of the fastening j4. Thus it will be seen that the outer rings, G G', and their operating mechanism are suspended by cords, ropes, or chains, and are susceptible of being raised, as in Fig. 4, and thus depress the Scrapers M, which are attached to the levers L, or to be lowered, as in Fig. 3, and thus elevate the said Scrapers, the use of which will be hereinafter described.

Instead of the ropes la la any ordinary form of lever may be attached to the device for raising and loweringthe outer rings, G G', and-their operative mechanism, and I therefore do not confine myself to the precise method shown for producing the above-mentioned result. u

The levers L are constructed similar to that shown in Fig. 5-s-that is, with the hole m2 nea-r IOO the front end and a notch, mf, in its rear end, to receive the end oi' the links, which are secured therein by the pivot-bolts l1. h.

The scrapers M are iiat plates of metal with rounded corners M and are secured to the levers L by the bolts or rivets i. On the scraperblades, or on the front end ot the levers L, are secured pulleys u or oz-whichever form may be most convenient, as shown. It' the horizontal pulleys n are used the one at the right of one scraper is connected to the one at the4 left of the neXt scraper by rubber bands I?, so that each set of scrapers may yield outward orbe drawn toward each other. lf the vertical pulleys n are used they are connected together by a rope, l, which passes over each alternate pulley, and then upward over a pnlley, P2, attached to the ltop A, thence downward, and is provided with a weight, P3, thus giving to the scrapers a yielding motion similar to that produced by the rubber bands P.

Several sets oi' t-he adjustable scrapersMand levers L are arranged around the rings F Fl G G', and some are arranged higher than others, so as to present the inner edges of the scrapers at various heights and have their inner edges all pointing toward one common center, as shown in Fig.

The top A is provided with an opening, B, across which is a bar, G, having in its center a pulley, D, mounted in hangers ul a, over which the rope b operates. Said rope passes along the top A to another pulley, (not shown,) and thence downward to the windlass b2. rlhis windlass may be of any ordinaryconstruction, having a double crank, b' b2, and a clutchcoupling, a3, in the center, each crank being adapted to operate independent of the other, or in connection with each other, as will be hereinafter described. The' other end oi' the rope b is attached to the plug I of the tongs.

Ihe tongs are of peculiar construction, to wit: The outer case, H, is hollow, and has a form similar to that shown in Fig. l, in which is pivotcd, as shown, the two jaws J J. The lower end of the jaw J' is provided with a straight spur or point, f', and the jaw J is also provided with a curved spur, j', as shown. The central tapering plug', I, operates between the upper ends of the jaws and forces the lower ends of said jaws together when they are attached to an animals snout. The lower tongs, U, consist of the frame or case fr, having an inner pulley, p, attached to the arm m, which extends upward, and is provided with a spur, u. On the other side of the tongs is a hinged arm, s, also provided with a hooked spur, u. The cord or rope k3 passes through a hole in the bottom of the tongs U, over the pulley p, and is made fast to the hinged arm s, as shown. The rope k3 then passes under the pulley l to the other windlass b', as shown in Figs. 1 and 2.

Having thus described the construction and arrangement of parts, I will now describe themode of operating my machine as follows, to wit: The animal from which the hair or bristles are to be removed is rst introduced into a vat of 'scalding water in the usual manner, after which the tongs H are attached to its snout and the tongs U to its hind legs, after which the windlass b is operated, and the animal is drawn upward between the scrapers M. Then the windlass b2 is operated, and the lines b and 7c3 drawn taut, thus stretching the animal between the two sets of tongs. When in this position the rings G G are raised, as in Fig. 4, and the two windlasses are connected by the coupling c3. The animal is then drawn upward between the scrapers M, which, by their inclined position and yielding nature, adapt themselves to all parts of the body of the animal, and scrape oft the hair and bristles as the animal is moved up. When the animal is drawn downward the windlass is reversed, and the rings G G also are moved down, thus giving the scrapers M an upward inclination as the animal descends; the remaining portions of hair or bristles are removed, after which the animal, thus deprived of its hair or bristles, is removed and another substituted, and the operation again repeated.

It will be observed that the springs e e' e2 e3, links KK K2 K3 K4 K5K6 K7, and rubber bands P or cord P' ,permit each scraper to operate independent of its neighbor, and that each scraper will follow each and every irregularity of form in the animalin line with said scraper, as the animal passes either up or down,

land by the number of said scrapers, each of which performs its own work in the same manner, as just described, it is impossible for an animal to be drawn between them without having its hair or bristles most completely removed in the most rapid and economical manner.

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

1. In a machine for scraping hair and bristles from animals, the stationary rings F F', with springs e e3, and links Kl K3 K5 K7, combined with the movable rings G G', also provided with springs e e2, and links K K2 K4 KG, and the levers L, with scrapers M, all pointing to one common center, as and for the purpose specified.
