'To theattainment oft-heaforesaid Vobjects and ends, my invention consists inthe novel details olf construction `andin the combination, connection and arrangementy of parts,

hereinafter more lfully described andthen pointed l outfin the claims. In jthe accompanying drawings, show 5mg an illustrative embodiment ofthe invenftion,

essarytoiremove-the entireknifein orderfto Figure v l `-is a .perspective vievv showing a machine embodyinge'the invention, in which `thelknife'is'shown in theelevated or'retracted position, .the rear comb down inthe clampinggposition vand ithe fronty Acomb ele-` vated. l

"Figure 2is a ldetailperspective 4vievv kshovv- "ing a ,portion of the cutter-bar and attached blades (the extension at one gend of the cuty lterbar which acts as aguide being-shown).

Figure i3is`a det-ail cross section ,showing the guides, a Vpiece of fur in ,position thereony (fur side down) and the straight comb land the zigzag combin engagement with the fur to holdthe same in positionover thelrnife ready to*be acted on bythe through .the .rar and eut the saine in zigzag is pressed downwardly by the lrnife into the knife-gap Without severing any of the hair of the fur). e i

Figure 5 is an inverted plan view of a portion of the front comb.` p p Y Figure 6 is a rear vien'v showing" a piece of fur separated along a zigzag line, by my invention, the upper portion showing the fringe of the fur extending below the Zig- Zag edge of the skin While the lovver portionshows merely the zigzagedge ofthe skin With no` fur along t-hezigzag edge.

Figure?v is a. rear vievv of tvvo `pieces of fur represented in Figure G as the same appears when seWed together. l Y `Figure 8 is a vieivshoyving the face portion of the fur (in this view themeeting edges ofthe skin Where the same are sewn together'are obliterated due tothe zigzag cut-ting of the fnr and the lapping of the hair over thecut). i

In the drawings in which like numerals of reference indicate like parte in allthe` figures,1is`the base Which carries the uprights 2, thellatter being'cross-connected at their Vtops by plates 3; the base 1, uprights 2 and connecting plate ,3 constitute the frame of 4 the machine.

The uprights 2 have parallel vertically disposed `guide slots l in which the `ends'of the comb holding bars 1,3- and 24p are mounted `for vertical movement.

The uprights `2 eachalsohave a `vertical slot 5 in which the frame ends 7 of the zigzag lrnife bar Garelocated and have up and doWn movement.

The knife, vvhose construction is one of the features of my invention, comprises la. bar V6 bent into a'zigzag form, save at its ends, which ends are flat,"li^e in the same plane, and act as guides,in` cooperation vvith the slots 5.; To thisbar 6 is secured (preferably by screws 10) series of blade sections 8 whose `meeting edges are in. complete contact so as to leave no substantial space "between the same. i The blades have V-shaped cutting 'edges 9 as shovvn. y Y

Snitably located: handles 11 -are attached to kthe bar 6 in order that the bar maybe con- Y veniently pressed down to eect the cut, and,

in order that thelrnifemay be held up ont of the Way When not in use, it maybe mounted on springs 12 suspended'from the plate 3.

,The rearholding device comprises a combbar 13 that carries the comb blade 14 Whose l teethf15 serve to engage the skin and hold itv `down on the guide plate again referred to. i y. The combld` has itis teeth 15 arranged in groups, each group being spacedapart to provide gaps 16, the centers of which are l`ocated inalignment vvith the adjacent apexes ofthe lrnifegap 38. This arrangement insnres more perfect cuttinlenof thefur at the Vaperres of the zigzag edges.

34 hereinafter v on thefopposed faces ofthe uprights 2 to hold down the bar 13 in any `position at which it is pressed. v

. ln order` to hold the comb-bar 13 elevatedv when .it is not being nsed'as Welles to Coopera/te with the `detente 2O and Vracks 22N in holding the bar placed, suitable springs 23 are suspended from the. plates 3 and connected to certain of the ears, clearly shown in Figure1. l j' j,

s lt Willfbe noted that .the teeth ofthe rear comb are located in a straight line acrossthe Width of the machine, the purpose of whichl Willlater appeal'. Y

j Another holding' device is provided in the front of the machine` toceoperate With the rear.holdingcevice just described. Thisfrontholding device comprises a comlrbarC 2li to `which is` suitablyV secured the blades which have teeth 26.` It Will be noted that the blades25 and their teeth 26 lie in zigzag order following the contour of the zgzag knife-gap, thereason for which Will Y late-r appear. f

Apertured ears 27 on the top 4of the bar 24 constitutebearings forthe latch rods 28,-

which like the rods 1S, have finger lpieces 29, i

detents 30 and detent springs 31'. Racks 32 arejalsoplrovided on theuprights 2`to cooperate wit the detente` in thesame manner as the racks 22 cooperate with the detents 20. Suspending springs 33; are connected With the plates 3 and to ear'sBTa-s shown. j j

`Located on` the base 1' directly beneath the combs ligand 25 are thefguide plates 3d and 36` respectively. i ,At least one of these plates isadjustable toward and from themothei" to widen or restrict the lrnifelgap 38 as ldesired.

ln the drawings I vhave shoivn the Vrear plate B4 secured'by screvvs in a non-adi plate 36 i justable manner While the `front adjnstablyfastened-at 37 the `base 1."

The fur skin-is indicated in the drawings by the referencenumeral 39 andthe hair by the nunieral t() While thestitching by VWhich the two pieces are seivn together is indicated ingldigure 'l'l the numeral L11.'

t Operation.

ln operation, the guide plates 34 andl are first adjusted to the proper `Width, Where` upon a piece of fur is laid over the guides indicated by the j dotted lines in Figure 1. vThen the rear comb teeth 15V are brought into engagement `Withftlie skin side of the fur. As `soon as the bar 1 3 which carries the comb 14 is lowered into engagement .with the fur,

the spring detents 20 at each end immedi- Vately'engagewith.the corresponding'racks 22 `promdedaipon the :inner sidesofthe vertical standards ofy the frame. The fur -is then suitably stretched by handover the guide plates-and the front .zigzag comb is llowered 4into position as illustrated in Figures y3:and

4.` As 'soon the `front comb has been alowered the spring fpressed detents'30 will engagenviththeir respective racks 32 and -hold the comb to I its adjusted position and the fur firmly stretchedbetwee'nfthe combs.' The Vknife bar 6 isthen lowered'by hand, the operator graspingithc handles 19 andbringing the zigzag edge 9 ofthe blades intofengagement with the fur and cutting the same as indicated in 'Figures Sand 4.

Attention is called to the fact that by reason of the provision of xthe rear comb -withteeth in straight alignment'transversely' o'f the machine, the operator can .the more readilystretc'h the fur smoothly across the Eknife-'gap38 and V,inasmuch asthe rcarcomb has its groups of teeth spaced apart to providethe ygaps 16 whichalign withthe apexes of the recesses, a more perfect cuttingof the fur atthe apeXes islobtained when "the cutting iknife descends. f

-soon as ithecutting operation has'been performed the knife "will Abe raised fby `the springs 12 and thereupon the comb bars 13 and 24 are released by pressing together the fingerlpiecesfatEthe'center of the bars, where by the detents at the ends thereof are released of their engagement with their ren. spective racks and the springs 23 and 33 serve to raise the comb bars to their inoperative position.

It will be noted that the knife does not come in contact with the walls of the knifegap as a shear but the gap is of larger area than the cross sectional area of the blades. The reason for this is that in cutting the skins the blades will push aside the fur or hair as indica-ted in Figure 4 so that when the skin is removed from the apparatus it will have a projecting fringe of hair as indicated at 40 in Figure 6. The corresponding part of theskin which has been severed will have a smooth edge as indicated in the lower half of Figure 6.

It should also be understood that the cutter bar 6 should be so adjusted within the guideways 5 that when the same is in the lowermost position the edges of the. cutting blades cannot engage or touch the upper surfaces of the Vbase so as to prevent all liability of injury to the hair of the fur (see Figure 4).

While mylinvention has been particularly designed for use in cutting fur oranimal pelts it is obvious that it is equally applicable to cutting fabric having a pile on one side. n
