MACHINE FOR DYEING FUR-SKINS.

To all whom it may concern: 7

Be it known that I, MALCOLM DIOKERSON, a citizen of the United States, residing in Belleville, in the State of New Jersey, have invented certain new and useful Improveskins has been hitherto a hand operation, the

dye being applied to the fur and distributed uniformly by a brush'in the hands of the operator, the fur skin to be dyed being. laid upon a suitable table and removed therefrom and hung upon a suitable frame in order that it may dry without pressure upon the 'fur and without contact of the flesh side of one skin with the wet fur of another skin. This hand operation is necessarily slow and expensive. Efforts have been made to produce a'machine capableof performing the operation rapidly, but hitherto such efforts have not resulted in a thoroughly satisfactory machine, mainly because it has sought to handle the fur skin in the same manner that a skin without fur might be handled satisfactorily, the necessity of avoiding application of the dye to ,thelflesh side of the skin and of avoiding the matting of the fur by pressure thereon while the fur is still wet, not being fully' recognized or provided for. By the present invention it has been sought, while making use of such main elements as have been used heretofore,

so to improve the construction as to meet in a satisfactory manner the peculiar necessities of the satisfactory treatment of fur skins.

It has been the further object of the invention to produce a'machine which has coinparatively few parts, all of which are ao cessible readily for cleaning, renewal and repair, is comparatively inexpensive,--'and is capable of performing the intended operation rapidly and efficiently. The invention will be fully described hereinafter with reference to the accompanying drawings in which it is illustrated and in which Figure 1 is a topview of one form of a machine which embodies the invention. 7

The working parts of the machine are supported upon a suitable frame which comprises a lower frame a provided with level-- ing screws a, a drip pan a which also forms a part of the frame, being secured by bolts (1 to the lower frame members a, and upper frame members or cheek pieces a secured to I the lower frame members by bolts a The upper frame members or cheek pieces a are provided with bearings a in which is mounted askin carrier, so that it is removable readily when necessary. The skin carrier might be a rotary drum, as shown at b in Fig. 10, or, as shown particularly in Figs. 5, 7 and 8, it comprises a frame I) having trunnions b to be received in the bearings a", a curvedshoe 6 covered by a non-friction and non-corrosive lining 6 such as a sheet of celluloid, bearings at'b and b the latter being adjustable, as by, a screw 6 rolls 6 and 12 mounted in the bearings b and b 'respectively, and an endless belt 72 of rubber or other suitable material, which encircles the rolls 6 and b and the shoe 6 and is caused to travel in a counter clock-wise direction, a driving pinion 6 being fixed on the end of one of the rolls, as

the roll 6 and engaged by a driving chain as hereinafter described. The shoe 6 is suitably curved, as shown in Figs. 5 and 8, and the tension of the belt can be regulated by adjusting the bearings b of the roll 6 J The skin carrier, whether a drum or a belt, is wetted more or less with the dye, as will be explained, and it is very necessary to remove from the surface of the belt or trough and is applied to the fur.

For this'purpose a squeeze roll 0 is mount- ,ed in movable bearing boxes 0, pressed toward the skin carrier b s orin s c and su ported'by brackets c suitably mounted in is a dye trough (Z which may be suitably supported betweenthe upper side members a by spring-pressed rolls (Z, carried by lugs (Z2, and normally engaging holes formed in the frame members a. The dye is supplied to the trough through a suitable pipe (Z at the middle of the trough, and the excess of the dye, not taken up by the brush hereinafter described, flows out from the trough at its ends, as indicated at (Z falling thence upon the pan a to be collected and re turned, if desired, to the trough throu, ;h-the piped As the brush referred to rotates there might bea tendency of the dye liquor to eddy in the trough and pile up more or less near the ends. ,To overcome such tendency, the trough is provided, near each end, between the outlet andthe inlet,'with a partition (i which is lower than the end of the trough, as shown in ig. 5, so that the dye liquor at the end of the space occupied by the brush flows over the partition and escapes through the opening rltwithout pil= ing up in the trough at the end of the brush.

The fur skin is held with the flesh side againstthe endless belt b as hereinafter described, and moves with it under the shoe '5 with the fur downward. A dye-applying, cylindrical brushe is supported in suitable bearings so as to be rotated at a moderate speed and so as to be partially submerged in the dye liquor in the trough CZ, the direction of the rotation being clock-wise so that the direction of movement of the surface of the brush, where it contacts with the fur, shall be the same as that ofthe fur. By this means the'dye is taken from the 7 Any eX- cess of dye thrown oil by the brush is thrown forward, to fall into the pan a .or to be taken up by the first rubbing-in brush 7 which is likewise mounted in suitable bear-v lugs and 1s rotated also in a clock-w1se direction, but at a much higher speed than the brush 0. A second rubbing-in brush 9 is also mounted in the frame to rotate in a clock-wise direction at a relatively high 7 draft.

speed. It will be understood that the bearings of the brushes 6, f and gare adjusted as indicated at e f and 9 in Fig. 2, so that the brushes may. bev moved toward or away from the skin carrier The effect of the two rubbing-in brushes-is to spread the essary action of the rapidly rotating brushes,

f andg,'while at the same time they must be held by. such means that the dye liquor shall be applied to all parts oflthe fur. To effect this result endless cords h are mounted on grooved guide rollers h", if, h and h and bear against the underside 'of the skin carrier, as clearly indicated in Fig. 5. One or more of the grooved rollers are driven, as hereinafter described, so that the lineal speed of'the cords shall be substantially the same i as that of the belt 5 and so that the contacting portions of'the cords and the belt vor skins shall move in the same direction; In order to avoid the necessity of providing adjustable means for maintaining the tension of the cords, the rollh receives a slightly higher speed ofrotation than the rolls h and 7 It, so that the workingportion of each cord is maintained under suitable tension by the The slippage is 'inconsiderablel It is highly'important that the wet fur, as 'it comes from the last rubbingd'n brush g,'shall not be subjected to pressure, so that'the wet fur shall not be matted down. To accom- V plish this result the grooved roll ifi'is placed at a considerable distance beyond the roll 1b,

thereby providing a table of cords on which each skin, as it leaves thelast'brush, shall rest lightly and at the same time move fordrying without having any other skin resting upon it; The cords are smallln s ze and do not in pract ce prevent a'unlform d1str1-- bution of the dye onthe fur;

A small gear on the shaft of the carrier roll 6 is engaged by the chain 72. so that the carrier 6 may be driven.

The operation of the improved machine has been sufliciently explained that no further description therefor is necessary.

It Will be understood that various changes in details of construction and arrangement Will be made to suit difi'erent conditions of use and that, except as pointed out in the accompanying claims, the invention is not limited to the precise construction shown and described herein.
