To whom it may concern:

' Be it known that I, ROBERT E. JORDAN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hair and.

Refuse Removersfor Dehairing-Machines;

and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being had to the accompanymg .drawings, and to the numerals of referencemarked thereon, ,which form a part of this specification. I

This invention relates to an improved type of hog dehairing machine having associated therewith mechanism for recovering the hair and refuse scraped from the carca mes operated upon by the machine. In this inventhe hair to a point of discharge, allowing the water to drain therefrom during the removal of the hair. V

It is also an object of this invention to construct a machine adapted to dehair carcames passed therethrough and provided with mechanism to receive the hair and refuse scraped from the carcasses and carried by the flow of water within the machine to said mechanism, which operates to remove said hair and refuse, allowing the water to drain therefrom during the time of removal thereof. I y b v It is furthermore an object of this invention construct in combination with a carcass dehairing machine mechanism to receive the hair and refuse removed from the carcasses comprising a conveyer mov ng over a perforated partition, said conveyer acting to sweep the hair. and refuse upwardly thereover, allowing the water to drain therefrom, finally discharging the hair and refuse t at a convenient point. j

It is finally an object of this invention to provlde in combination with a carcass dehalring machine means for elliciently removing the hair taken from the carcasses from the machine. v i

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. a

In the drawings:

Figure 1 is a side elevation of a machine embodying the principles of my invention.

Fig. 2 is an enlarged central longitudinal ection taken therethrough, with parts shown in elevation.

Fig. 3 is a section taken on line 33 of Fig. 2. I e I Fig. 4 is a fragmentary top plan view of the machine with Fig. 5 is a detail section taken on line 5'-5 of Flg. 4.

As shown in the drawings:

The machine consists of a long tank strucparts broken away, and v ture 1, having a partition 2, extending transversely thereacross near one end thereof-affording a scalding compartment 3, on one side and on the other side a compartment 4, within which thescraping and dehairing mechanisins are mounted for operation upon carcasses passed through the machine. For this purpose rollers 5, 6, 7, 8, and 9, respectively, are journaled transversely within the compartment 4, and trained the'reover is a conveyer' 10, having lags extending transversely thereacross and spaced upwardly to afiord clearance therebeneath and acting to contact the carcasses and thrust the same along. A

curved perforated partition wall 11, is dis- I posed near the forward end of the conveyer beneath the same and another similarl constructed partition wall 12, is dispose "near the otherendof said conveyor. Mounted in the scalding tank 3, and trained around rollers 13 and 14, respectively, is a small flight conveyor 15, which acts to elevate carcasses from the scald tank over into the dehairing compartment 4. v

A pair of dehairing mechanisms for the carcasses passed through the dehairi'ng compartment 4, are provided, which as shown,

are exactly similar inconstruction and each consists of chains 16, trained about sprocket wheels 17 and 18-, respectively, said chains having scraper blades 19, secured thereon, and one of said pair of dehairing mechathe partition 2,

, which the respective rollers 27, are mounted, and trainedthereabout and about an idler nisms disposed above said conveyer 10, in position over the curved perforated partit1on 11, and the other, over the other parti- ,tion 12. Said respective sprocket wheels 17 m'eans'are mounted at two points beneath. the upperzflight of the t conveyer 10, as

and 18-, are mounted in 'a frame 20, which is suspended from cables 21,-which are trained over sheaves 22, mounted on the top wall of the tank structure 1, said cables having secured on their ends counterweights 2.3, so. that adjusting'movements of the dehairing mechanism may take place as the carcasses pass therebeneath. Additional dehairing roller 30, is a driving chain 31, a drive being imparted'thereto from a drive wheel 32, secured on the" same shaft with the-sprocket wheel 29, at the rear end of themachme. A tension carriage of any suitable construction,

denoted as a whole by thereference numeral 33, is suspended on said chain intermediate the sprocket wheel 28, and sprocket wheel 29,

I atthe rear end of the machine to afford the requisite tension upon the chain. v The respectiveeconveyers 10 and 15,- may be driven from any suitable-source, not shown,

but, however, are connected for simultaneous movement by a chain 34, trained about sprocket wheels 35 and'36, respectively, se-

cured upon'the shaft upon which the respective rollers ,5 and 14, are mounted,

'An auxiliary. wall 37, is built at one side a of themai'n tank structure 1, as clearly shown in Figs. 3, 4, and 5, to afiord a hair receiving compartment, and, said compartment communicates with the compartment 4, through narrow vertical passages 38 and'39,

respectively, disposedat each end of the 4 compartment 4, as clearly shown in Figs. 2

and ,5; Mounted in inclined position within said hair receiving cOmpartmentviB' 'a-Perforated partition 40, with its lower end disposed adjacent the passageway 39, and itsupper end adjacent the passage 38, so that the hair and refuse received with the water through the passage 39, may be moved upwardly on said'ipartition by a scraper conveyer 41, provided with lags 42, which move over the upper surface of said partition.

The chains of said scraper conveyer 41,-

are trainedabout pairs of sprocket wheels 43, 44, and 45, respectively, of which the pairs 43 and 44, are journaled above the upper edge ofthe wall 37, and the latter pair 45, of which-are journaled within the lower rear'end of the hair receiving compartment, as clearly shown in Fig. 5. A driving sprocket wheel 46, is secured upon the same shaft with the pair of sprocket wheels 43, for the purpose of imparting a drive to said scraper conveyer 41. I

The operation is as follows:

The carcasses are introduced into the machine into the scalding compartment 3, and are then moved by the conveyer 15, upwardly over the partition 2, into the dehairing compartment 4. The carcasses then roll downwardly upon the curved'partition wall or floor 11 beneath and into the field of operatlon'of the first group of scrapers 17, and after a few moments ofrotation therein, during which a dehairing operation proceeds, are thrust upwardly by one of the lags of the conveyer '10, over and in contact with the scraper blades 25, which move be-.

neath the carcass end, of course, clearing the upwardly spaced lag of. the conveyer -10.

The carcasses .then roll down beneath the secondgroup of scrapers at the rear of the machine finally being thrust upwardly over the second group of scraper blades 25, and discharged at the rear of the machine; In each instance, the respective scraper blades "25-,- movebeneath and, in fact, support the carcass which is thrust along by a conveyer lag, the latter,.of course, being spacedup- 'wardly an-amount sufiicient to permit clearance'thereof beneath'the lags as they move thereover. The hair and refuse removed from the carcasses is carried by the water through thelong vertical passage 39, in the slde of the compartment 4, and 1s then scraped upwardly over the perforated partition 40, and to a point of a discharge, the water of course draining through 'said perforated partition and passing out of the hair compartment through the vertical passage 38, and back into the compartment 4. Thecirculation of water from the compartment 4, through the passageway 39, into thehair removing compartment and from the hair removing compartment back through the passage 38, into the dehairing compartment, is induced b movement of theconveyer 41,1ongitudinally through said hair removing compartment.

.I am aware that various details of con- .struction may be varied through a. wide range without departing -fromthe principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
