; }1c1 i .,(c1. 149-2 6) My invention relates generally to means for clipping and trimming furs; and an important object of the invention'is to provide means whereby the fur skins are exactly held While being carried past a setof revolving knives which clip the hair to any set length, whereby complete and accurate trimming of the skin is achieved in one operation, wherein the hair over the entire length i and width of theskin is uniformly clipped;- Another important object of my invention'is' to provide a simple and practical arrangement of this 'character which does not require extensive handling of the skins;v and which can be operated by unskilled persons. I

l5- Other important objectsv o'f'my inventionwill be apparent from a reading of the following de.-'

scription taken in connectionwith the drawings, wherein for purposes of illustration 1 have shown preferred embodiments of my invention. Y In the drawings:

Figure 1- has a right hand elevational view of an'embodiment of theinvention. 1x. Figure 2 is a back view of Figure 1 taken looking from right to left in Figure 1 with the cutter removed. 1 Figure 3 is a longitudinal vertical sectional view taken through Figure 1 the section being taken on approximately the line 3-3 of Figure 1. Figure 4 is a transverse vertical sectional-view 30,; taken through Figure 2 the section being'taken on approximately the line 4-4 of Figure 2.

Figure 5' is a transverse verticalsectional view I taken through another embodimentiof my in-- vention. 35: In the drawings, and referring-first to the embodiment of the invention shown in Figures 1 through 4, the numeral 5 generally designates a A suitable support on which are "mounted two end plates 6 which are annular inform and have 4()"- radially'extending lugs I which act as journals for the various roller 'shaftsto be described. The" annuli- 5 receive therethrough the suction pipe 8 which at a point between the plates 6" has tangentially flaring sides -9 and I!) which define a H 4,57 suction opening therebetw'een facing the back of the machine.

J ournaled in the respective lugs l are'the' upper and lowerroller shafts II and I2; and thefront andback roller shafts I-3"and M, the shaft II 5.0 5 having a surrounding roller I I, the shaft [2 a roller I2, the shaft l3 a roller l3 and'the shaft 14 a roller l4, all of which rollers engage the inner side of va cylindrical casing l5 which is revoluble by reason of this arrangement and has 55 over its surface .the perforations :IS a portion of which are adapted to'register with the opening definedby the suction pipe flanges 9 and ID as they come into registry therewith. The shaft 13 extended beyond its supporting lug land has a pulley l'l thereon which may be driven'by a suite 5 'l5at'the" required rate of speed.

-I-Iaving their opposite ends journaled in spaced 'ablevb elt"(notshown) for revolving the cylinder members of thesupport '5 are roller shafts l8,

I9 andjZfl-which have trained-thereover'the belt 10 2| whose upperfiight 2 2 is conformed to and runs against theibottom of the revolving cylinder l5 as 'clearlys'hown in Figures 1 and 4.

Vertical projections 23 on the respective plates -6 mounted L-shaped brackets 24 whichare piv l5 oted as indicated by the numeral 25 to the pro--' jections and carry at their outer ends or front ends the shaft 216 which mounts a heavy roller 21 over which is trained a. belt 28 whose lower'flight 29 conforms to and rides upon andis driven bycon- 20 tact with the. surface of the upper part ofthe revoluble drum l5. Another shaft 30 is supported at" its opposite ends-byvarms-"3l pivoted as indicated bythe 'numera1v32 to the back part of the projections 23' and carries a smaller roller 33 over 25' which the belt '28 also'is trained. In addition the arm'silihavemounted thereon the beam 34 to which are attached and from which depend the pressure fingers35 which engage the back part of the-cylinder l5 as clearly'shown in Figures 1 30 and 4 andal'so in Figure 2. g The remainingarms of the L-shaped levers 24 have mounted thereon the shaft 36 which contains the roller 31, The shaft 36 is mounted" in a" slide bearing arrangement 38 on each'of the 35 5 armsof the'lever s 24 which by reason ofwhich a screw arrangements!) is adjustable to different g positions to ride against the upper flight 40 of the belt28.. v, r

A contracting spring H is stretched between 40 ond tensioning spring42 is stretched between'the v roller part of each arm 3| and each of the, pro- "jection's 23- as}illustrated in Figure 1 for tensioning the roller 33 against the upper back part of the revolving cylinder and in addition to tension the spring fingers 35 against the back ofthe revolving cylinder.v Mounted'on the support 5 immediately .to the rear of the revolving cylinder I5 is the cutter cylinder 43 which is mounted on a rotaryshaft 44 and is shielded by a shield 45. The cutter '55 the same against the upper part of the cylinder and acts to make the same engage the cylinder evenly throughout the length and width'thereof,

the skin being engaged by the lower flight 29 of the belt, and the belt holds the: skinin engage? ment with the cylinder I5 until the cylinder with the skin thus held thereon turns to a point where the perforations l5 register with the opening in the suction pipe, whereupon the suction in' the" suction pipe will strongly and evenly secure the skin to the exterior of the cylinder so that all unevenedges will be exactly held. The skin and alllparts'thereof thus held against the exterior of the cylinder by suction, is carried down under the tensioning fingers 35 until exactly in a position to have theiur thereof clippedby the cooperating knives 45 and 41.

Thearrangements are such that as the edge of the skin passes the region of the 'clipping, the same :will engage between therbelt 2|" and the lower part of the cylinder;;and pass from the region of the suction-opening :'to the bottom .of'the cylinder, the exact positioning' of the skin being maintained by the.:portion of the skin which is over the suction hole and that. portionof the skin preceding the same which is held in place on the cylinder by the belt 2i; whereby the skin, throughout its operative engagement with the cylinder 15, is held in anexact, smooth,,and even contact with the drum, so: that absolutely uniform clipping 'of thexhair thereof throughout the length'and width of the skin is accomplished by passing the same once through the machine. The position of the stationary knife 41 and of the revoluble knives 45 may be altered to achieve the cutting of the hair of the skin at-the desired length. In Figure15 of thedrawings another embodimentof the invention is shown and'comprises a large 'revoluble cylinder 50 which has-trained thereover a perforated belt 5! which has a horizontal flight 5-2 which is the upper flight and an angulated flight 53 which is the lower flight, The

upper flight 52 is passed across the horizontal top. .5 t'ofi-a suction conduit 55 which has'in its top an opening 55 whose presence causes the exertion of'sucti'on: through the holes or perforations 5'! in the belt 5i. The conduit 55 is projected from the suction pipe 53'around which the belt 55 moves as indicated, and brackets 59 projecting from the conduit, carry spring fingers 58 which bear against the back of the belt passing aroundthe pipe 58 as clearly shown in Figure 5 to guide the skin past the fur cutting stationary knife 41' and the revolving knivesn ifi, the latter being mounted on a shaft which is driven from .a suitable power source. is provided'forprotecting. the. rotary cutter.

' Engaging the right hand portion of the bottom leading- An' overlying shield 4-5" upper flight 52 of ,the belt back of the suction opening '56 and the belt carries the same along until the opening 56 is reached, whereupon suction is transmitted from the conduit 55 through the holes 51 in the belt to the skin, whereby the skin is positively evenly held on the belt and transportedtoward and into engagement with the springj fingers '60 which hold the same in the proper position for clipping of the hair thereof by theknives. As indicated by the numeral (ii the suction opening 56 extends down along the back 'of the suction pipe 58 so as to retain the suction effect for. holding the skin until the same hasipasse'dthe clipping position; andhas engaged itsforward edge with the flight 22 of the belt 2l'-, which then mechanically holds the skin until the skin has passed the related position.

, It is to be noted that neither the perforated cylinder l5northe perforatedbelt 51 has to-be perforated over its entire widthand length or held to the cylinder or belt by the spring pres sure fingers 35. Where-more than one type of work is tobe done by one machine,.shields of impervious material may be applied to a completely perforated cylinder or belt to close off the undesired perforations.

Although I have shown and described herein preferred embodiments .of my invention, it is to be definitely understood that I do not desire to limitthe application of the invention thereto, and any change or changes may be made in the materials, and in the structure and arrangement of the parts, within the spirit of the invention and the scope of the subjoined claim.

What is claimed is: a

A machine for clipping the fur or hair or skins comprising a cylinder having perforations therein, means for rotating the cylinder, a suction chamber inxthe cylinder having an opening therein covered by a limited area of the inner circumferential part of the cylinder, means for creating spring fingers carried by the second pair: of arms and engaging the cylinder at a pointadia cent the point where the clipping means engage the fur or hair of the skins.
