The present invention relates to butcherlng apparatus, and more particularly to a xmachine for trimming the headsof hogs and the like. 5 An object of this invention is to provide a machine for removing-the snouts from the heads of hogs, and to facilitate such operationand admit of the quick and continuous consecutive removal and disposition of the snouts, so that the operation may be. carried on without interruption and a relatively large number of heads may be handled per hour, and a larger output beobtained over the present methods than with the apparatus heretofore used.

Another object of the invention to pro- 7, vide a machine which will pull the snouts from the heads and deposit the snouts upon a worktable or the like in position of easy access for further steps in the trimming operation, and thus save considerable labor and time over the old type of pullers which drop the snout-s beneath the table into a receptacle .and from which the snouts have to be lifted to the table.

I A further object is to provide a machine which pulls full length snouts from the heads regardless of the size of the latter, and to thus realize a better yield on the head skins, and further to save labor in the head skinning operation. v a y A still further object of the invention is to 7 provide a machine possessing the above characteristics and which is of relatively simple construction and easily kept clean, and which has no complicated parts which may readily get out of order, and which insures a relatively low cost in upkeep and operation. I A further object of this invention is to provide a machine which is adapted to be driven or operated from any accessible source of power, and which has to its capacity.

With the foregoing and otherobjeets in view, the invention will be more fully de- 'scribedhereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer practically no limit as to like orcorresponding parts throughout the several views,

Figure 1 is a side elevation, partly in section, of a hog snout puller constructed according to the present invention, the dotted lines showing the position of a head on the machine ready to pull the snout therefrom.

Figure 5 is a detail perspective viewof the pulling point removed from the'd'rum, and

Figure 6 is adetail perspective view of the support or holding plate upon which the heads of the hogs rest during the operation. j

Referring to the drawings, the machine may be mounted upona work table 10 of any suitableconstruction and which presents a' preferably horizontalfiat top surfacetoward one end of which'the pulling device is mounted. The pulling device comprises a pair'of brackets. 11 in the/upper ends of which is journaled a'transverse shaft 12fand about which is concentrically mounted a drum13 by means of two or more spaced armslc'f As shown in Figure 2 the arms 1.4 are spaced apart along the shaft 12 forengaging the drum 13 at or near its oppositelateral edges between the arms 14 and within the drum 13.

The drum 13 is provided on it's outer peripheral surface with one or more pulling points 15. In the present embodiment a pair of these points is shown, the same being diametrically. opposed upon the drum and the points '15 facing in thesame'direction so as to project downwardly at the forward side of the apparatus as shown in Figure 1. .Each pulling point,-as shown in detail in Figure 5, has an attaching plate 16 which is preferably i so as to leave'an uninterruptedannular spacecountersunk in the surface of the drum 13, as

shown in Figure 3, and secured thereto by screws 17 or the like admitting of the quick and easy removal of the points should they become worn or broken. The pulling point is provided with a pair of prongs which are offset outwardly from the plate 16 and extend substantially lengthwise thereof but at a tangent to the plate 16 which preferably is curved lengthwise to conform to the outer surface of the drum. The plate 16 is PlOVlClGChWltll a longitudinal slot 18 which is in radial and circumferential alignment with the space between the prongs of the pulling point and also with a circumferential slot 19 formed in the drum 13.

The drum 13 is provided at its innerslde opposite each pulling point with a pan of brackets 20 between which is pivotally mounted a tripper 21. Each tripper 21 comprises an arm which has a short portion 22 pro ecting outwardly through the

slots

18 and 19 and through the space between the prongs of the pulling point 15.

The outer end of the short portion 22 1s provided with a beveled head 23 which extends from the plate 16 outwardly and is adapted to engage the snouts caught upon the prongs for forcing the snouts therefrom as will hereinafter appear. The trlpper 21 1s mounted upon a pin 24 carried by the adJacent pair of brackets 20 and upon which the tripper is adapted to swing. The inner end of each tripper 20 comprises an elongated arm which extends at an angle to the portion 22 and which extends over one side of shaft 12 so that the shaft 12 serves as a means to limit the swinging of the tripper in one d rection, and the inn-er end of each trlpper 18 provided with a weight 25 ad ustable lengthwise thereon and secured in ad usted posltion by a set screw 26 or the like. The weights 25 are disposed at opposite sides of the shaft 12 so that when the weights are raised above the shaft by the rotation of the drum, the weights fall and operate the trippers 21.

The shaft 12, upon which the drum 13 1s fixed, may be provided with a gear wheel 27 at one side of the drum and it'may mesh with a pinion 28 supported on a drive shaft 29 which may extend from any suitable source of power or transmission means for. driving the pinion and gear wheel. The drum 13 111 one practical embodiment maybe driven at a speed of approximately 6 revolutions per nnnute although this speed may be increased or decreased as is found practically desirable. It is also understood that the drum may be turned by any other means than shown as the gear wheel and pinion are merely by way of example and found as one satlsfactory means of operating the device.

The table 10 is also provided at its forward end with a rest or support 30 in the form of a plate which is bent transversely near one end to provide a supporting web 31 located at the inner end of the plate and terminating in a base flange 32 adapted to rest upon and be attached to the table 10. The forward end of the plate 30 has a base flange 33 which is bent at a slight angle to the plate and is adapted to be permanently attached to the table. The plate 30 is thus secured in an inclined posi tion upon the table, and is located between the forward ends of the brackets 11 and be neath the forward side of the drum 13. The plate 30 faces outwardly and upwardly, and is preferably provided with upstanding prongs3t arranged one near the upper end of the plate and two in spaced relation near the lower end of the plate. The severed head of the hog is adapted to be placed upon this plate with the snout uppermost and toward the drum, and the prongs 34 are adapted to anchor and hold the head from shifting or displacement during the operation of removing the snout from the head.

Referring now to Figure 3 particularly, the head of the hog is prepared for the removal of the snout by marking or slitting the skin at opposite sides of the head along the line 35 so as to direct the severance of the snout 36 with the skin and the portions of snout meat 37 which are located'in the cavities at opposite sides of the skull 38, the snout 36 when initially marked or cut is turned back in the position shown in Figure 3. The head is placed upon the support 30 with the snout uppermost and toward the drum 13. The heads may be successively positioned and removed upon the support 30 with considerable ease and speed so that as the drum turns the pulling points 15 are successively brought into engagement with the snouts 36 and quickly strip the snouts with their adjacent portions from the heads.

As the pulling points 15 move downwardly with the drum, the weights 25 iall below the shaft, as shown in Figure 1, and the tripper heads 23 are held in retracted position at the inner ends of the pulling points. 15. The pulling points 15 travel downwardly and carry with them the snouts 36 until they reach the opposite or rear end of the table 10 when the weights 25 are at that time moved into position above the shaft 12 and fall toward or on the same, and move the tripper heads 23 outwardly in the pulling points'15 and eject or remove the snouts therefrom. The snouts thus fall upon the upper surface of' the table 10 in position of easy access of the trimmers for further operation in skinning and otherwise treating the snouts.

. It is obvious that various changes and modificationsv may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being reclalms.
