My invention relates to andhas for a purpose the provision of a simple, substantial and inexpensive machine particularlyadapted although not necessarily, for use in removing the rind from bacon, and by which the removal of the rind can be effected with the utmost ease and dispatch, thus greatly facilijtating the preparation of the bacon for use and eliminating the skillful labor required in present methods of manually cutting or otherwise removing the rind; from'the bacon. I will describe only one formof rind removing machine embodying'my' invention-and will then point out thenovel features thereof .in claims; V

In the accompanying drawing,

Fig. 1 isa view showing in plan partly a broken away, one form of skin removing machine embodying my invention. 7 Q Fig. 2 is a vertical sectional view taken onthe line 22 of Fig. 1, and' Fig. 3 is a view in end elevation of themachine shown inthe preceding figures. 7 Referring specifically to the drawing in similar partslin each of the severalviews, my invention in its present embodiment comprises a frame F preferably constructed of sheet metal to providea rectangular base 10 having upstanding flanges 11 along itsside edges. The base 10 is provided with openings through which fastening members 12 are adapted to be extended to secure the frame to a horizontal support such as a table or bench 13. The base 10 and flangesllcO- operate to provide a trough adapted to freely receive a slab or side of bacon therein; and jour'naled in the flanges 11- to span the latter horizontally, is a shaft 14 on whichthe rind of a piece of bacon insertedin the troughbe low the shaft is adapted to bewound.

Theshaft 14 may be angular'in cross secton such as square for example as illustrated, to provide edges for preventing slipping of the bacon rind during winding there of on the shaft, or may be provided with 'pros 'jections or teeth 15 at intervals along its length adapted to vent slipping of'thelatteron the shaft.

The shaft is adaptedto be rotated in a which similar reference characters designate penetrate the rind to precounter'clockwise direction as viewed 2 either by means of power or by a crank 16 fixed to a shaft 17 journaled in theflanges 511; the shaft 17 having also fixed fthereto a .M.

pinion gear 18 meshing with a relatively large gear 19 for increasing: the power d veloped at the crank. j ,7 7

As the bacon rind is being wound on the shaft 14, the'bacon is caused to traverse .a path" different from that of the rind so as to v separate the latter from the bacon by "a'stripping or tearing action. To this end I pro- 'vide an abutment designated generally atA for directing or guiding the bacon tangentially from the shaft, and advanced between the flanges 11 asits rind is wound on the shaft. In the present instance this abutment comprises a round bar 20 terminating at its ends in right angularly disposed parallele'x tensions 21 slidably mounted in. U shaped brackets22 fixed to the flanges 11, to support the 'b'ar 20 substantially] at the level ofv and 1 parallel Withthe shaft'14 for'movement hori- 'zontally towards and away from the shaft. 51;:

The abutmentis normally urgedtowards the shaft 14 by means of coil springs 23sur roundingthe extensions 21 and bearingat' one end against pins 24 extending diametrically through the extensions, and at their other ends against one of the arms 25 brackets. The movement of the abutment towards the shaft is limited to a position in which the bar 20 clearsthe-teeth 1 5, by means of other pins 26 whibh-are adapted to engage v the .arms 25 ,ofthe extensions, H y

' Apiece of bacon when inserted between the shaft 14 and the base 10 is adapted to be urged upwardly towards the shaft and to this end I provide a platform 27 on fwhich the bacon is adapted to rest, pivotallymount- 7 ,7

ed at one end on the base 10, by means of pins .28-extending through ears ,29 and 30 on the platfor'mand baserespectively. The freeend of the platform is normally urged upwardly .by means ofcoil'springs 31 interposedbe tweenthe platform and base 10 and receiving projections 82- and'38 formedonthe platform 7 and base respectively, to prevent lateral displacement ofthe-springsl The yieldability e V of the platform provides for sides or slabs 3 ingly maintain the rod in engagement with of bacon of different thicknesses, and insures that the bacon will be held up to the shaft 1 L regardless of the thickness of the bacon.

The operation of the machine is as follows: Let it be assumed that it is desired to remove the rind from a side of bacon. The

. bacon is first slit under the rind from one end by a suitablev knife to form a flap of rind.

The platform 27 is now depressed and the end of the bacon inserted between the platform and the shaft 1d, which the free end of the previously formed flap of rind is passed upwardly between the-shaftla and the rod 20 and then wrapped about the shaft, The crank 16 is now operated-torotate'the shaft 14: in a counter-clockwise direction as vielwedin. 2. As the forward end' of the .bacon from which the flap of rind has been removed, extends in advance of the bar 20 it .will be clear that upon continued rotation of the shaft l thfl rind will be wound'nponthe shaft, whereas winding of the bacon on the shaft will be prevented and'the bacon dierect ed or'guided by the rod'20 tangentially from the shaft so as to be] fed or, advanced overv the platform 27," thus stripping or tearing the rind from the bacon; As the coil of rind on the shaft la increases in diameter, the springs 23' permit'the rod 20 to be forced away from the shaft, and operate to yielda means. for directing or guiding apiece of bacon for movement along a predetermined path, and the shaft 14 a means towhich the bacon rind is attachable, for causing the rind to traverse a different path from the bacon in a manner to effect stripping ortearing -of therind from the bacon. i

Although I have herein shown and described only one form of rind removing machine embodying my invention, it. is tobe understood that various changes and modifications may be made therein without departing from the spirit of the invention and the spirit and scope of the appended claims. I T

I claim:

A rind removing machine comprising means to which the rind of a piece of bacon is attachable, means for mounting the first means for rotary movement-to efiect' winding j ofthe bacon rind thereon, means for direct-' ing the-bacon tangentially from the" first means as, the bacon rind iswound on the latter, to thereby efie'ct stripping of the rind from the bacon, and means for urging the last means against the rind wound on the first, means for the purpose described.

2. A rind removing machine comprising means to which the rind of a piece of bacon is attachable, means for mounting the first means for rotary movement to efiect winding of the bacon rind thereon, a movable abutment for directing the bacon tangentially from the first means as the bacon rind is wound on. thelatter, to thereby efi'ect stripping of the rind from the bacon, and means for urging the abutment against the rind wound on the first means yet rendering the abutmentfree to yield as the coil of bacon rind increases in size.

3i A' rind removing machine comprising means to. whichthe rind of a piece of bacon is attachable, means for mounting the first meansfor rotary movement to effect winding of the bacon rind thereon in coil formation,

means for directing the bacon tangentially from the first means as the bacon rind. is wound on the latter, to thereby elfect stripping of: therind from the bacon, and means for normally urging the bacon bodily towards the first means, yet yielding as the'coil of bacon rind increases in size.
