JOHN Konn- HnPr, a citizen of the United States, and a resident of the city of Chicago; county of Cook, and State of Illinois, have invented certain new and useful Improvements n Carcass Scraping and Cleaning Mechanisms and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. v The present application-constitutes a division of my prior application for patent, for , carcass scraping and cleaning. mechanisms, Serial No. 384,287,filed J My 17 1907. i This invention relates to improvements in scraping mechanisms and particularly to that classadapted for scraping, polishing and cleaiiiig hogs. . Heretofore in carcass scraping machines the carcasses have been supported on or suspended from a suitable conveyor and passed between scraping devices suitably arranged to act thereon. Where the carcasses are supported lengthwise on the conveyer there has always been a strip extending the entire length the carcass that could not be acted class of machine in which the carcass is suspended by hooks there is always a' portion where the hook engages that is not scraped. Eurthermpre machines employing conveyors which necessitate carriages and hooks being used for engaging the carcasses are quite expensive to install, require considerable space, constantly need repairing and consist of a casses can be dispensed 'with. ' "Also the hog scraping mechanisms heretofore have only been adapted to clean the carcass and have-not in any way aided in forcfing thegcarcasses-through themachine. ) It is 'aii ohject of this invention to providea carcass scraping machine in hich Specification of Letters Ietent. upon by the'scraping mechanism and in that cnncass sc'aarmo AND GLEANINGMEGHANIBM. .moved past the scrapers at the desired rate or may remain .in one place in the machine until completely cleaned and in which the v PatentedJan.19,1915. Serial No. 354,287." Divided and this application filed March 23 181?. Serial No. 885,834. i carcasses are continuously rotated or turned, 7 thereby exposing all parts to the action of the scrapers and to provide a scraping device in which it is practically impossible to dislodge a carcass while being acted upon by the boaters. a It is also an important object of this invention to provide a machine in which flexible scraping mechanisms are employed and in which the scraping mechanisms coact with the aforesaid conveying or moving and rotating mechanism for rotating and forcing the carcasses through the machine. It is also an object of this invention to provide a device of the class specified in which the rotating and moving carcasses are partly submerged in fluid at a suitable temperature whereby the hair, dirt, and refuse provide a device in which the carcasses are, i if necessary, further scalded while being acted upon by the scrapers should they not have been properly scalded in the scalding vat ;or tank but entirely eliminating the use of igspraying and pumping devices. It is also an object of this invention to provide a device in which the carcasses are delivered anism and a gravity exit therefor after scraping. a It is a further object of this invention to provide a highly eificient and g'reatly'simplified machine of both small and great caby gravity to the moving and rotating mechpacity and the capacity depending upon the I avoided and which requires a minimum number of attendants. a The invention consists of the matters. 7 hereinafter described and more fully point .cd out and defined in the appended claims. -'therethrough from the oonveyer a. On the drawings: Figure 1 is a longitudinal vertical section of a device embodying my invention, with the scraping mechanisms arranged transversely the travel of the carcass. Fig. 2 is a topplan view thereof. As shown in the drawings: A, indicates a scalding vat or tank constructed of any suitable material and size anddiaving the rear bottom wall, a, thereofpinclined upwardly and rearwardly. Journaled in the sides of the tank at the upper and lower ends of said inclined wall a, are shafts a'a on which the elevator 11?, is supported. Adjacent the rear end'of said scalding tank A, is a water tank B, provided with suitable water inlet 6, and steam or heating fluid inlet b, and with a suitable washout pipe or plug 6. ' Said tank B, is constructed of sheet metal orany other preferred material and comprises a bottom wall 6 side walls I); and end walls bb, of a height, width and length to c'ontain the various mechanisms therein. The wall 6, of the tank B, is placed against the top of the inclined wall a, of the scalding vat and is provided with a swinging or automatically'closing door b, above the top of the inclined wall of the scalding tank, which is of a length to admit the hog lengthgise 'idl secured to the-side walls I), and end wa l b", of said tank is an inclined platform 5, which extends rearwardly from the bottom of the door opening and the lower end thereof is directed horizontally or at a slight angle upwardly. Journaled in the side walls 6", of said tank B, is a beater shaft C, on which are bolted or otherwise rigidly se-' cured flexible beaterarms c, constructed of any suitable material such as canvas, chains, v the outer ends of said heater arms 0, are a plurality of sets of flexible or. rigid blades c -c0 having their outer ends'curved outwardly, and, as shown, arranged two abreast but obviously any number may be used in a set. l - Journaled in suitable hearings in the side walls 6 below and at the rear of the beater shaft C, is a roll, drum or cylinder D, to which are rigidly secured in any preferred manner bars or plates (1, of suitable metal or other material, which are shown as angle irons securedto the roller by one flange, and the other flange is directed radially outwardly and parallel the axis of the drum. It -15 to be distinctly understood that in the construction shown, any form of roll or drum may be used and either flexible or igidbars 0r ribs may be used with any swinging doors mayrclose said exit. form of drum. The specific construction used'depends entirely upon the specific demands of the user, e: 9., for a large slaughter house a metal cylinder may be used with. teel ribs which are slightly flexible to yield should the machine operate above a given velocity, or a yielding cylinder may be used such as a solid canvas or rubber cylinder, and either yielding or non-yielding ribs. On the other hand. in the smaller plants where one hog is operated on at a time, either a metal or other cylinder may be used with ,7 either yieldingsor non-yielding ribs, and thev construction for any user may vary to meet the exigencies of the specific case. A su table driving pulley D, is secured the drum shaft (1, atone end and sprocket M wheels (F-(Z are rigidly secured to the beater shaft 'and drum shaft 61 of the drum D, outside and at the-opposite side of the. tank. and a chain (1", is trained there around, whichdrives the beaters. Above and slightly -to the rear of the center of the roll or drum D, just suiliciently for thobars (I, to pass, is-a platform'di which is shown-us horizontal to the endwall 71", of the tank'and is then inclined down If of the tank B, above the platform (i and pivoted thereto is a door 6, curved toward the opposite end of thetank and rear, vvardly of its projecting lower edge, said door is provided 'with a spring atch e, normally locking the door in closed position. A cable or c'ord e trained around suitable pulleys e e *e is secured "to" the latch e, and extends w thin convenient reach of an 'attendantfor'opening the door to admit the cleaned carcass through the opening in the end wall 6 upon'the platform X, and if desired a suitable strip of flexible material G, "s'uch 'as canvas or The b.-1nds,s'traps or bars are made'of material such as .steel, rubber orothe r suitable m terial. the object of which will be hereinafter described; The operation is as follows: The .hogs, after being suitably scalded. in the vat or tank A. are moved. upon the elevator of, which delivers them through the door I), and the carcasses move by gravity to the end of the platform. bfiand upon the roller D. Inasmuch as the-bars-tl, are parallel with the axis of the roller upon rotation thereof the bars at each revolution engage the hog and rotate or turn the same continuously. The hog is not moved longitudinally, inasmuch as the roll or drum is not spiral and the scrapers whichrotate ,opp'ositely from the direction of rotation of the drum P e s r t e eras-se V onghly cleaned, the cord enamel the carcasses the same is being rotated. The beameprevent the carcass from being thrown rearwardl from the. rotating drum and the rigid door. e, prevents the carcass from being moved by the heaters forwardly beyond the roll, so that at all times the carcass is contimlously spinning at a high rate of speed in position for thebeaters to act continuously on all parts thereof. The door a has a-lower projecting edge which also serves to scrape and dehair the rapidly r0 tating carcass. The water level'in the tank may be any preferred height, blit is shown slightly above the roller D, approximately on a level with the middle of the carcass so that the carcass is lying androtating in water (which is heated or not, as found necessary) and the heaters acting thereon not only scrape the bristles therefrom, but polish the carcass. After the carcass is thoring the catch and opening the door and the, carcasslis forced upon the platform 0!, and is delivered by gravity upon the operating table. or bench X. The cord is released, and ' the operation repeated. It is seenthat the and pumps are eliminated, and that the carcase is Washed clean as it is rotated continuously in water. Furthermore, should the carcasses not be sufiiciently sca-lded for remoral of the bristle, the carcass may again be scalded in the tank as the scrapers act thereon. v Many changes of construction may be varied. without departing from the principles of this invention, and I therefore do not desire to limit this application for patent as to details, or otherwise than necessitated by the prior art.
