Cross bars 29 are connected-with the lower 1 portions of the side members by bolts and nuts 30.

The frame is arranged to besecured to extend in various directions from supports for purposes hereinafter described. Such securing means may 5 .The top of the frame has a pedestals! ex-., I tending therefrom. The pedestal is shown as" having the operatin parts for the head and the jaw mounted thereon so as to supportthe same from the frame. The pedestal is shown asv com- 1 prising a plate A2 which'serves as an inner shield or wall for, a feeding space 43 of my improved device. The margin ofthis wall is preferably substantially annular and is preferably provided with a marginal strengthening flange M,

which merges. into brackets 45 at the base of the-555 porting wall or pedestal.

necting with the top 2 of the frame.

The pedestal is provided with a bearing 48 near its middle and extending perpendicular thereto, the inner portion of the bearing being connected with the pedestal by ribs 49 for strengthening the structure. A feed shaft 5! suitably driven is rotatable in the bearing and. extends through the pedestal. A feed wheel 52 is secured to said feed shaft as by a key 53 and set bolt 54, and forms a feed wheel for the carcass head. It operates in the feeding space 43 at the side of the pedestal and preferably overhangs laterally outward from the frame. The feed wheel has an outer peripheral portion 51 which coacts with the jaw portion of the carcass head for positioning the latter, and with feed fingers 58 which are arranged about the outer periphery of the feed wheel, being preferably equally spaced thereabout.

The feed fingers are located in sockets 59 in said feed wheel and are secured in said sockets by taper pins 60 in registering taper holes in the wall of said socket and the base of said finger. The fingers are of greater width than thickness, being provided with side rabbets $2 for forming flat faces at their sides, the greater width of the fingers extending in the directions of the feed to resist the great pulling strains upon the fingers during the feeding of the heads and to present as little crushing area to the jaws consistent with their pulling stresses, to avoid as much crushing ofthe jaw as possible in the pulling operation.

A horn 651's provided, along which the carcass head is fed in the feeding or pulling operation. It is provided with flanges 66 at its respective sides, bolts 67 passing through the flange at one of its sides and through the supporting wall 42, nuts 68 being threaded over the threaded ends of said bolts for clamping the horn to said sup- The horn is provided with a track 69, along which the jaw side of the head is fed, the major portion of this track having a curvature presented to the feed wheel which issubstantially concentric with the outer periphery of the feed wheel or path of the feed fingers, and ccacting with the feed fingers in their paths along the track for pulling the jaw along said track.

The horn has an entering portion 19 substantially round in cross-section and curved outwardly from the major portion of the track recedingly from the feed wheel. This entering portion has a reduced outer end if to form a receiving end of said horn, providing for ready reception 1 of the mouth of the carcass head thereabout, it

being understood that the mouth end of the head is pushed about the receiving or entering end of the horn, with the jaw or under side of the head presented toward the feed wheel, and the normally upper or skull side of the head presented away from the feed wheel so that the horn acts on the head between the jaw and the skull.

The horn is provided with outwardly presented tracks 12 which spread laterally at both sides of the longitudinal middle portion of the horn and also diverge from the feed wheel and the track nearest to the feed wheel, forming a three point wedge which spreads laterally and angularly with relation to the feed wheel for relatively spreading the jaw and the skull, and, due to the pulling action of the feed fingers and feed ,wheel upon the jaw portion of the head, relatively separates the skull portion and the jaw portion of lateral edges of the wall adjacent to and con-.

the head, so that the jaw portion moves along the track 69 adjacent to the feed wheel and the skull portion moves along the tracks l2 spaced therefrom, said tracks forming a wedge therebetween and causing separation between the jaw portion and the skull portion of the carcass head.

The jaw is U-shaped, having a front or bridge end and sides, and, after separation, the front end rides upon the track v$9 adjacent to the feed wheel, and the sides of the jaw arrange themselves at the sides of said track 69, the feed wheel feeding the jaws along said track adjacent thereto off the outfeeding end 73 of said track, for permitting the jaws to fall upon the table or be led to such other point as desired for further operation thereon. The outfeeding end of said track may have a delivery rod 14 connected therewith, as by providing said delivery or out? feeding end with a slot 15 and the adjacent end of the rod with a tongue 16 received in said slot, a taper pin ll, for instance, located in registering taper holes in the walls of said slot and in the tongue, connecting the same in manner so that the severed jaws may be readily fed and guided therealong.

A stripper Blhas stripper fingers 82, which project toward the feed wheel, and are arranged at the respective sides thereof and about the feed fingers in such manner that the separated jaws are positively stripped from the feed wheel and the feed fingers. The contact faces 83 of the stripper fingers slant toward the outer periphery of the feed wheel and coact with the jaws, being arranged preferably on a curve tangent to the approaching portion of the outer periphery of the feed wheel and inclined toward the oncoming feed finger so as to readily release the severed jaw from the feed Wheel and the finger. The base 84 of the stripper is provided with flanges 85 at the respective sides thereof, one of which is secured to the pedestal or supporting wall 42 by clamping bolts 36 and nuts threaded thereover.

A shield EH forms an outer wall for the feeding space 43 in which the feed wheel and its fingers rotate. This shield or outer wall may also form a strengthening means for the operating portion of my improved device by being clamped to the other of the flanges 66 of the horn by clamping bolts 92 and nuts threaded are located at thetop portion of the outer shield or wall, in the various positions assumed by the frame, ashereinafter explained, and at the side of said outer shield or wall opposite to the side at which the stripper is located, in such various positions of the frame, to stiffen the structure, as see Figs. 8 to 15 inclusive. I

The driving means exemplified comprise an electric motor H, which is preferably a reversible electric motor, or an electric motor in which the direction of rotation of the rotor may be reversed for rotating the feed wheel in opposite directions for the purposes hereinafter described. The motor is shown adjustable for adjusting the driving means operated thereby. Thus, the motor is clamped in depending'relationby clamp bolts I02 and nuts therefor to an adjustable motor mounting plate I03, shown-as a :pivoted plate provided with bearings Hi4, in

pivot rod beingheld in axial direction by a set bolt Ill? threaded in one of said bearings. A threaded stud I08 is fixed in theplate 24 and extends through a hole in the motor plate; Nuts threadedabout said stud at opposite faces of said motor plate adjust the motor plate and clamp the same in adjusted positions, regardless of the position of the motor with relation to the feed wheel, that is, whether the motor is below, above or to either side of the position of the feed wheel, or regardless of the direction in which the frame extends from its support, whether thatv support be the table, an overhead support, or a wall or *post. 1

A speed reducing device I I5 is mounted on the top or plate 24 and is clamped in operative position by means of clamping bolts and nuts H6 therefor, the bolts passing through enlarged mating holes II? in feet H8 of the frame of the speed reducing device, a washer H9 being located under the head of each of the bolts.

The rotor shaft I2I of the motor has a'pulley I22 secured thereto, a flexible drive connection I23 being received thereabout and about a pulley I 24 on a shaft I25 on the speed-reducing device I I5 mounted on the frame. These pulleys are exemplified as sprocket wheels'andl the flexible connection is exemplified as a-sprocket chain. Adjustment of the motor plate Hi3 adjusts the tension of the flexible drive connection.

The supporting member and the cap member- "have enveloping walls I42 for enclosing the worm and worm wheel.

The shaft 5! is shown as the feed shaft, and is held endwise by having the inner end of the hub of the feed wheel 52 coact with the bearing,

andproviding the shaft with a collar I43 fixed to. said shaft by a set bolt I44 and coacting with the outer end of'the' bearing I36.

In operation, referring particularly toFigs. 1,

2, 4 and 6, the carcass head, after having had the pushed along the horn until it is contacted by 'a fingerz58 of the rotating feed wheel 52, whereupon the carcass head is fed by said feed. wheel along the tracksGS, I2, the feed fingers 58 contacting the jaw and the outer periphery of the feed wheel holding the jaw toward the track 69, the major portion of which is substantially concentric withsaid outer periphery. The fingers are of greaterwidth than thickness, their width dimensions being parallel with their feeding paths for exerting great feeding force and imparting great'feeding strength to said fingers. These fingers are also readily removable from and insertible in the wheel forrepair and replacement of the same. I

As the head is fed'along the horn, the jaw and the skull portions thereof are relatively spread by the wedge form of the horn and the spreading and separating relation between the track 69 and the coacting tracks I2 for-separation between the jaw and the skull, the jaw being fed along the track 69 of the horn by the feed fingers to the outfeeding end thereof and the skull dropping or-being removed from the outer face of the horn for further operations on the jaw and the skull; The severed jaw is ofsubstantially U- form, its front forming a cross member which rests on the horn, and the sides or jaw bones arranging themselves by gravity at the respective sides of the horn. The jaws may drop 'or be removed from the outfeeding end of the horn, or they may be fedalong an outfeeding rod (Figs. 3 and 6), extending from the outfeedi'ng end of the horn. If desired, the connecting gristle and muscles of the joint between the jaw and the skull may'be' severed or chiseled for more ready separation of the same while passing along the horn. Y

The stripper M is provided at the outfeeding end of the horn and coacts with the feed fingers for ready release of the severed jaws from said fingers. l

The-horn, the stripper, the feeding space and the feed wheel are arrangedtoproject or overhang laterally from the frame and the pedestal thereof at one side of the frame, providing free space under, above and at the front and rear thereof for unobstructed placement, feeding and delivery of the head and its severed jaw and skull. The feeding space between the walls 42 and oiispreferably open at the outer margins of said walls fo-rready access into the interior of said space, making all parts thereof readily'accessible. p 1

The frame is constructed to project in various directions from supports; the horn, stripper and connecting means between the walls are rea'dily I adjustable about the axis of the feed wl1eel;.the

jected in different directions; and the direction of rotation of the feed wheel is reversible, to

adjust the horn and stripper into most convenient positions and directions of operation and for rotating the feed wheel in most desirable I direction according to the direction in which the frame projects and the most desirable direction of. feeding movement of the carcass head, making my improved device extremely adaptable for most desirable, convenient and economical operation and for most desirable positioning of the same with relation to the positions of operatives and the desired positioning and passage of the carcass heads and their severe-d jaw and skull, and the parts to be severed therefrom. 7

The feet 35 of the frame are provided with holes 33 through which suitable lag screws 34 pass into the support for the frame. This support may be the table 37, from which the frame projects upwardly, as exemplified in Figs. 8 and 9.

The support may be an overhead ceiling or framing Il, from which the frame of the machine depends, as exemplified in Figs. wand 11. The support may be an upright wall or post I52, from which the machine frame projects laterally, as exemplified in Figs. 12, 13, 14 and 15, the frame projecting toward the right in Figs. 12 and 13, and toward the left in Figs. 14 and 15. The direction in which the feed wheel desirably rotates is exemplified by an arrow in each of the Figs. 8 to 15, and the desirable direction in which the horn and the stripper respectively project is shown in each of these figures.

It will be noted that in each instance there is free space under the horn, the stripper, the feed wheel and the feeding space for freedom of movement by the operator of the machine and for otherv operatives adjacent thereto for convenient and speedy manipulation of the carcass head and its severed parts and for trimming of the same.

Referring to Figs. 6 and 7, the walls 42 and 9| are provided with mating holes for suitable fastening means for the born, the stripper and the connecting and spacing means in the various positions and directions of projection and operation of my improved device. The desired direction of feeding movement of the feed wheel is desirably obtained by providing a reversible electric motor as the power applying means.

The inner wall 42 is exemplified as provideo with four groups a, b, c, d of equally spaced holes, these groups of holes being at the respective right angular dimensions of the margin of the inner wall at substantially right angles to the frame. Each group comprises an outer set of two holes and an inner set of three holes centrally positioned with relation to said right angular dimensions. The holes of the outer sets are designated respectively al, a2; bl, b2; el, 02; and dl, d2. The holes of the inner sets are designated respectively a3, a4, a5; b3, b4; 03. c4, c5; and d3, d4, (25. The holes of the outer sets are preferably located respectively in radially extending lips 70, l, m, n.

The outer wall is preferably of a form similar to the form of the inner wall, but I prefer to rotatively adjust the outer wall with relation to the inner wall, whereby most of the holes which would otherwise register with the holes in the inner walls and two of the radially extending lips may be dispensed with, and all of the holes in the outer wall will at all times be filled with fastening meansto avoid leakage through the outer wall.

Thus the outer wall (see Fig. 7) may be provided. with four groups of holes 6, f, g and h, at right angular dimensions thereof. The group e comprises an outer set of two holes el, e2; group f comprises an inner hole f l; group g comprises an outer set of two holes of, 2; and group h comprises an inner hole M. The outer holes mentioned are .at greater distance from the axis of said outer wall than said inner holes, to correspond with the positions of the respective mating outer holes and inner holes having similar exponents in the inner wall 42. The outer holes in the outer wall register with given ones of the respective outer holes in the inner wall, and the inner holes in the outer wall register With selective ones of the inner holes in the inner wall.

By this arrangement all of the holes in the outer wall will be filled by securing means in assembling the parts, and the outer wall may be adjusted about the axis of rotation of the feed wheel so as to locate the outer wall in such angular position as may be desired or advisable according to the direction in which the frame of the machine is projected from its support, whether upwardly or downwardly or laterally in either direction, and the direction in which it is desired to feed the carcass heads. The outer sets of holes are located in oppositely projecting lips o, p, which are adapted to be registered with opposite ones of the respective pairs of lips in the inner wall to locate the outer wall in selective right angular positions.

When my improved device is positioned in upright position with the infeeding end of the horn at the left and the stripper at the right, as shown in Fig. 8, the bolts for the horn are in the holes cl and 02 in the inner wall and in the holes g! and g2 in the outer wall, and the bolts for the stripper are in the holes b4 and D5 in the inner wall and in the hole M in the outer wall, there being only one bolt connecting the outer flange of the stripper with the outer wall, which has been found sufficient for rigidly connecting the walls and stripper. The upper connecting bolts for the walls are in the holes a! and (12 in the inner wall and in the holes el, e2 in the outer wall. The left-hand connecting bolt is in the hole d4 in the inner wall and in the hole M in the outer wall, and the right-hand connecting bolt is omitted as the walls at this side are held in correct rigid relation by the stripper and its bolts,

When my improved device is positioned in upright position with the infeeding end of the horn at the right and the stripper at the left, as shown in Fig. 9, the positions of the securing bolts and connecting bolts are as explained in connection with Fig. 8, except that the direction in which the horn projects is reversed, and the bolts for the stripper are in the holes d3, d4 in the inner wall and in the hole h t in the outer Wall, the con.- necting bolt at that side being omitted, and the connecting bolt being placed at theright side of the walls and located in the hole D4 in the inner wall and in the hole M in the outer wall.

When my improved device is in. depending position with the infeeding end of the horn. at the left and the stripper at the right, as shown in Fig. 10, the walls are in upside down relation and the bolts for the horn are in the holes a I, a2 in the inner wall and in the holes el, e2 in the outer wall, and the bolts for the stripper are in the holes (14, d5 in the inner wall and in the hole M in the outer wall. The end connecting bolts for the walls which are in this arrangement adjacent to the frame, are in the holes: el, 02 in the inner wall, and in the holes oi, oi. in. the outer wall. The left connecting bolt is in the hole D4 in the inner wall and in the hole id in the outer wall, the right connecting bolt being omitted on account of the connection of the walls by the side ofthe wall.
