Hoc-SCRAPENG MACHINE.

SPECIFICATION forming part of Letters Patent No. 301,707, dated July 8, 1884.

provements are to remove the bristles by pulling them loose, so as to leave them in condition for use 1n the arts,` and subsequently scraplng and cleaning the hog, the operations being separate and distinct, but successive and f I continuous from the pulling device to the scraping and cleaning device, and the work quickly and e'ectually done.

Referring to the accompanying drawings, Figure'l represents in side elevation my machine for scraping hogs to remove the bristles; Fig. 2, a top view of the same. Fig. 3 shows a side View of one of the reels to which scraping-blades are attached.; Fig. 4, a cross-sec'- tion of the reel, showing two only of the scrapingblades attached. Fig. 5 shows an end view of the non-revolving elasticring-scraper and the manner of connecting it with and supporting it in the frame in front of the reelscrapers. Fig. 6 showsa cross-sectionof one of the4 reel-Scrapers with its scraping-blade complete, and Fig. i is a side view and partial horizontal section of thesame on the line :c .c of Fig. 3.

In the operation of the machine, the hog is drawn through the scraping' appliances upon a table or platform, A, suitably supported. rlhe scraping operation consists of two separate and distinct steps or successive operations, therst oi' which is effected byadevicc which acts to pull the bulk or main portion oi' the bristles from the hog, and the second is to complete the removal of the bristles and to clean These pulling and scraping appliances are arranged in a suitable frame, so that the pulling appliance operates above the-table, while the scrapingreels operate above and below the table. This frame is arranged near the middle ofthe length oi' the table, and consists of a strong framing of side posts, a c, and cross-beams b, the latter carrying the hangers c c for the journalhogs of varying sizes.

Application iled July 13, 1883. (No model.)

i boxes d d of the scraping-reel shafts,which are arranged crosswise the table-one above and the other below it, as shown in Fig. l. Atthe front end of this frame the pulling device l? '(shown in Fig. 5) is arranged to receive the hog in the lrst opera-tion, from which the hog is carried to the scraping-reels. device 4consists of a ring of steel blades, said 'ring being made in two sections connected so as to yield in relation to each other, to allow the ring to open to receive and to close its scraping edges upon the hog, yor to conform to The blades S are, attached separately, forming a circle, to a single 0r to two strong bars, It, made of spring-steel, which are connected at their lower ends, R', to the table-frame at a suitable point beneath the table, and are curved each of a form Ysimilar to a semicircle, with their upper or free ends crossing each other, so that the scraping .ends of the blades will form a ringof springblades. The free ends t tof the bar or bars are confined by loops sto the frame-posts, and are loaded with weights A(to balance the force and adjust the blades to theshape of the body ofthe hog as it is pulled through the ring. TheV blades S occupy radial relations to the ring, and are oi' such a length and shape as Will give them the required pulling action, and to forni an unbroken line, acting t0 pull the bristles loose from the skin as the hog is drawn through the opening in the ring.

' The scraping reels B B consisteach of disks fm, a, fixed upon a shaft, aand asuitable number of iiat radial meta-l ribs, o, secured lequidistant to and between the disks. The ribs may be straight or curved toward the reel-shaft, and the scraping-blades B2 are sc- .cured to them by screw-bolts in position side by side, with their free ends extending a suitable distance beyond the circumference ofthe disks to give them the required elasticity. These blades are narrow steel plates, and are all of the same length, so that the line formed by their free scraping ends will be curved toward the reel-shaft, so as toform an opening between the blades of the two reels through which the hog is drawn. This terminal curved scraping edge may be formed by blades of equal length secured to the curved reel-ribs, or by` blades of unequal length secured to straight ribs. The scraping-blades are' sup- This pulling poited upon supplementary metal ribs, 02, secured upon the circumference of the disks and to which they are also bolted, and thus arranged may be used in single rows. I prefer, however, to use the scraping-blades in double rows to secure a better scraping action, and attach the second row to the outside' ribs so that their ends will extend beyond the ends of the inner row, both rows beingfastened to the outer ribs by the same screw-bolts. These blades may be made adjustable, so as to project them more or less from the reel, the outer ribs and the outer blades being slotted for the purpose. Each row of scraper-blades is provided with a guard rail, 1', secured to end iianges of the outer ribs, as shown in Figs. 6 and 7, and the'se rails may be made adjustable by slots in their ends, and they form rigid stops to receive the rebound of the blades as they are released from the scraping action. NVhen double rows of blades are used, each row acts with a separate scraping-line, as the blades of each row are placed lapping upon cach other, so that the scraping-lines will de scribe circles of different' diameters. These scraping-reels are arranged so that the blades of the lower reel will revolve above the table, and the upper reel is placed vertically over the lower one, so that their blades will lap each other as they are revolved, but leave an opening between their curved Scrapers sufcient to allow the hog to be drawn through between them to receive the action of each row above and below. The scraping reels are adapted to move toward and from each other to allow the hog to be drawn through them in contact with their serapers, and for this purpose the boxes of the reel-shafts are connected with weighted levers ff by sliding rods, the said levers being mounted in suitable brackets, e, and operating` to give the reels the required pressure upon the hog.

The table has a central longitudinal slot or opening within which an endless chain, Z, is supported to travel on a plane with the table, and forms the means :for pulling the hog upon the table through the hair-stripping and scraping devices, the hog being fastened to the moving chain by a hook. This pulling-chain is stretched upon sprocket-wheels K L, suitablysupported beneath the table,and is driven from the upper scraping-reel by a chain passing over a sproket-pinion, l1, on the shaft of said reel to a sprocket-wheel, G, on a short shaft, k, -having a sprocket-pinion, fi, from which a belt passes to the sprocket-wheel H on the shaft ofthe pulling-chain wheel K. The upper scraping-reel is revolved by a chain-belt, g, passing over a sprocket-wheel, F, on the shaft of said reel to a sprocket-wheel, E, on the shaft of the driven pulley C, which shaft gears, .by the cog-wheels D D', with a shaft below, having the sprocket-wheel E', from which the chain belt g passes over a sprocketwheel, F, on the shaft e of the lower scrapingreel, as shown in Figs. l and 2. These chain belts operate torevolve the scraping-reels in directions toward each other, and contrary to the forward motion of the chain running between the reels, as shown in Fig. l.

In the operation, the hog, being rst scalded, is placed upon the table, hooked to the chain, and pulled, by the connected working parts, through the fixed bristle-pullingring device P, which acts to pull the bristles loose and leave them in good condition to be used in the arts. From this ring or pulling device the hog is drawn through the opening between the scraping-reels, which are self-adj usting to the shape and size of the hog, their blades rapidly scraping off all'the remaining hair on the body, removing the dandruff and scales, and cleaning the skin. This operation is repeated in quick succession.

Referring tothe scraping-reels, the springs are of steel, of sufficient strength to give them the proper yielding and scraping action; Vhen the blades are released from operation on the body of the hog, they spring back and strike the guard-rail r, to throw off the hair and dandruii that adhere to them, and then rebound to their former position. This action is seen in Fig. G, in which the dotted lines show the blades as thrown back against the guard-rails, after being freed of the hog, and the rebound ofthe blades from the guard-rails.

The arrows 2 2 show the direction of rotation of the scraping-reels, and the arrow 3 the direction in which the hog is drawn through vthe reels.

I claim- 1. The combination, in a hog-scraping apparatus, of the table A and the self-adjusting scraping-reels B B, with a primary ring-scraping device, P, the scraping-blades whereof are rendered self-adjusting to the hog in a plane at right angles to the passage of the hog, and a pulling-chain, substantially as described, for the purpose specified.
