KFNHTEE STATES FREDERICK VJ. HORSTMANN, OF MAPLEWOOD, NEW JERSEY I LEANS FOR PRODUCING DESIGNS IN IURS Application filed September 22, 1925.

This invention relates to a machine and method of producing novel and ornamental pattern or designs upon the fur surface of pelts or the like and to the article produced thereby.

In the manufacture of furs, that is, in the industry which conditions animal skins for fabrication into wearing apparel, it is desirable to produce attractive and ornamental effects. The appearance of fur for use as garments or other purposes has heretofore been confined to improving the fur to bring out the natural lustre and other desirable qualities by various treatments including dyeing, plucking and shearing, all of which have been performed in devious man ners.

The present invention may include all of the various well known steps to bring out the pleasing qualities of the fur and in addition makes it possible to produce a surface of distinct pattern of permanent, definite and predetermined design, embodying, if desired, a color effect as well.

One method of producing a patterned pelt is to manipulate a shearing or other cutting machine so as to sever the fur in alternate stress or patches of predetermined configuration. That ES to say, a shearing machine may be operated in such manner that the fur may be shorn and left long and short alternately. This operation not only results in a novel and pleasing design in so far as a short and long nap is concerned, but may produce a two color surface, since in a great many skins the fur close to the hide is distinctly different in color from that near the ends. Or, if desired, the fur may be dyed to produce different color effects. For example, the fur may be dyed a light color with the ends thereof of a different and distinct color so that when the fur is sheared in accordance with my invention a differential color scheme or design may be produced. Also the fur, after being cut in accordance with the herein described invention, may have the tips of the longer hairs or fur dyed a distinctive color from the remainder of the fur.

This general idea may be carried out to give many variations, such for example as Serial No. 57,824.

producing a gradual dark to light surface where the fur next to the hide is lighter than the surface. In other cases the shearing machine may be controlled to out the fur so that portions of the surface of a skin will have fur of gradually increasing length from the center of said portions to the border edges of the long fur. On the other hand, the shorter fur may be of uniform height pro ducing a distinct and clearly marked contrast to the long fur.

An object of the present invention is, therefore, to produce fur products having the surface of a pleasing and predetermined pattern.

Another object of the invention is to pr0- vide a pelt having portions of the fur removed toproduce a design.

Another object of the invention is to utilize the variation in color between the surface and base of the fur on a pelt and to expose the lower portions of the fur in a pleasing and ornamental manner.

Another object of the invention is to provide a method of producing a pattern upon a pelt. 75

Another object of the invention is to provide a method whereby a pelt may be shorn to give a patterned surface.

Another object of the present invention is to provide a machine for removing pre determined portions of fur from a skin to produce a patterned surface.

Another object of the invention is to provide a machine for automatically shearing a pelt to produce a pattern thereon.

Other objects and advantages of the invention will become apparent as the following description is read.

As an example of a practical embodiment of my invention 1 may employ a fur shearing machine such as that disclosed in my copending application Serial Number 7,671, filed February 7, 1925. For the purpose of carry ing out the present invention 1 provide the said for shearing machine with a reciproca- 95 ble or floating conveyor for feeding the pelt to the cutters.

T he movable conveyor may be advanced to permit a shearing operation or retreated to permit portion of a pelt to pass unshorn, or too if desired the machine may be so adjusted as to cut the fur into gradually increasing and decreasing lengths so as to produce thereon in effect permanent Marcel waves. This operation may be automatic, thus a pelt when conveyed past the cutters will have the fur formed into a pleasing design. The spacing of the waves, their depth and height and arrangement with respect to each other may be varied within wide limits and therefore a great variety of designs may be obtained. Such for instance, as a wide strip and a narrow strip, equal strips, adjacent wide strips of short and long fur with intermediate strips of either long or short fur, intersecting waves, waves or sinuous formation, and tie like. These eilects are readily produced by suitable cam or other machine elements which. control the movement of the conveyor.

A machine by means of which a skin may have the rur removed in accordance with my invention is more clearly shown in the accompanying drawing in which Fig. 1 is a side view in elevation of a machine embodying my invention and is partly shown in section where cross-hatched.

Fig. 2 is a fragmentary detail view showing an eccentric or cam action to reciprocate the conveyor to and from the knives.

Figs. 3, e and 5 are diagrammatic representative views, in transverse cross-section, of skins having the fur severed to produce ditferent patterns.

Fig. 6 illustrates afur having transverse cut out portions, and

Fig. 7 is a section taken on line VHVTI in Fig. 6 and shows an undulatory formation of the fur.

The machine illustrated for practising my invention may comprise a suitable frame 10 to support the several operative parts of the machine.

Fur-shearing mechanism 11 may be positioned at the top or table portion of the frame 10 and may include a rotary cutter 12 and a bed-kink 13. The rotary cutter may be mounted on ashait 1e journalled in suitable bearings at opposite sides thereof, the bearings being integral with a bedplate 15 secured by tap bolts 16 to the top of the frame 10 and the bed knife may be adjustably secured in any suitable manner to a post 17 integral with the bed plate 15. A housing 18 may enclose the cutters and an outlet 19 may be connected to a blower or other vacuum credevice (not shown) to remove severed i the usual manner and to assist in bringlie for between the cutting knives.

loy 21 connected by a belt 22 to a pulley 23 rotatable with a shaft 24- ournalled in suitable bearings provider. in the frame 10. The shaft 2 1 may be provided with a driving pulley (not shown) for association with any s .aft 14- may be provided with a pul-v suitable source of energy as for example a of the motor employed. The shaft 24 constitutes the main driving member of the machine and is also provided with a pulley 25 to drive other mechanism as will presently be described.

The mechanism for conveying a skin to the knives may be of the same general construction as that shown in the above-men tioned copendin application, and may include a bearing bracket 26 comprising a pair of side plates 27 and 28 disposed at opposite sides oi the machine and su tably held in fixed relation to serve as supports for rollers 31 and 32 mounted on shafts 33 and 84, respectively, the latter being journalled in the side plates 27 and 28. The rollers 31 and in conjunction with a canvas belt or apron constitute a conveyor which as a whole is designated by the numeral 36. The shaft is journalled in adjustable bearings 33, having slot and bolt connections 34 to the plates 2'? and 28, set screws 4-5 being provided to cause an adjustment of the rolle 31 to tighten or slacken the belt 35 when the bolts of said connections 34: are loosened. Any other suitable means for applying or removing tension from the belt may, however, be employed.

As a skin is fed to the cutters by the conveyor it is held in firm contact with the conveyor by pressure members comprising a plurality of short rollers 37 rotatable at the end of arms 38pivoted on a crossrod39 mounted in extended portions ll of the plates 27 and 28. Springs &2 serve to maintain the rollers 37 against the fur to hold the same firmly against the belt 35. The rollers may be disposed end to end transversely of the path oi? movement of the fur and provide a continuous flexible presser element toallow for local variations in the thickness of a skin and it a portion thereof is thicker than the adjacent portion, the contacting section of the rollers may rise without disturbing the etl'ective contact of the remaining sections with the more uniform portions of the skins. This novel construction is more clearly snown in the above-mentioned copending application.

An additional roller 43 is provided to hold the skin against the belt 35 after the skin has passed beneath the conveyor. This roller may be rotatable on ashaft lt carried the ends of arms 45 of levers i6 pivoted on a shaft 4:? which may be secured in the side plates 27 and 28. The opposite arm 48 oi each of the levers 4.6 may be engaged by a helical spring 49, the opposite end oi which may be secured to the bearing bracket 2?. The roller 43 is mounted on said lever arms so that when desired the spring 49 may be disengaged with the levers and the roller released from contact with the skin. The apron or belt of the conveyor may be provided with any suitable means for holding skins for delivery to the knives. The present construction of a conveyor belt is shown with pockets 51 into which an end of a skin may be inserted by an operator feeding the machine, so that the skin may be positively passed beneath the rollers 3'? and in operativerelation to the knives.

The above description is generally the same as that set forth in the hereinbefore mentioned copending application, said machine operating to merely uniformly shear the fur of a skin.

The present invention, however, provides means for moving the conveyor 36 to and from the shearing mechanism 11 to produce a skin with the fur sheared at spaced intervals, as shown in Figs. 7 and 8. As will be noted by the example shown, the strips 53 represent fur left long or unshorn while the strips 54: represent shorn portions of the fur.

When employing a machine, as shown, to practice the present invention, It mount the conveyor 36 on rocker arms 55 and 6, mounted at opposite sides of the bracket s6 and the frame 10. The upper ends of the arms may be secured by bolts 55 to the plates 27 and 28 of the bearing bracket 26, thus providing a floating or reciprocable conveyor. he bolts 55 may pass through slots 57 to permit a tilting adjustment of the end of the conveyor djacent the cutters. The lower ends of the arms may be pivoted upon a shaft 57 mounted in bearings 58 integral with the frame 10. An oscillatory movement is imparted to the rocker arms by means of cam members 59, on a shaft 61, by en agement with rollers 62 mounted on levers or secondary rocker arms 63 pivoted in extensions 64. The levers 63 may be connected by links 65 fastened to curved portions 66, having the axis of the shaft 61 as a center, of the rocker arms 55 and The extent of the in and out motion of the conveyor 36 may be adjusted by disposing the ends of the links in the openings 6? in the curved portions of the rocker arms, a slot 6? beingprovided in the end of each link 65 to facilitate this adjustment. A spring 63 may be provided for each of the rocker (to to hold the rollers 62 in con tact \*i the cams 59.

The shaft (31 may be mounted in bearings on adjustable bearing plates 71 earings 72 at opposite sides of the d which will be more fully described hereiiafter. The bearing plate may be usted by bolts passing through slots 70 of the plates and threaded into the frame 10, locking nuts '1 0 being provided to lock the plates in adjusted position. The shaft 61 upon which the cams are mounted may be provided with a pulley 7 3 connected by a belt 74- to pulley 25, which latter 1s driven hereinbefore described, motion thus being 1mparted to the cams to actuate the conveyor to and from the Cllttlll mechanism.

Z3 Contlnuousmovement to the conveyor belt 35 may be provided in the following manner.-

The bearing plate 71 may be provided with an adjustable bearing T5 held by a bolt 76 which passes through a slot in a foot piece of said adjustable bearing. A shaft 77 mounted in bearing 7 5 is provided with a sprocket wheel 78 and a spur gear 1' The spur gear is disposed in mesh with another gear wheel 81 secured to shaft 61. Motion is translated from the shaft 61 through gears 81 and 79, the 79 causing a rotation of the shaft 77 upon which the sprocket wheel is mounted. A chain 82 may connect the sprocket 73 with another sprocket 83 secured. to the shaft 57 w iich is thus revolved. Adjacent the s )rocket 83 may be secured another sprocket 8 1 over which a chain 35 leads to a sprocket 86 secured to the shaft 83 to which roller 31 of the convoy r is fastened, motion being thus ed from the shaft 61 to the conveyor. iuicr 8? may be provided to take up slack in the chain 82 and adjustable or tension idler 88 may be provided to hold the chain taut, tension being applied by means of spring 89 and lever 91.

As illustrated in Fig. 2 an in and out motion may be imparted to the conveyor 36 by eccentrics 92 mounted on the shaft 61, the eccentrics engaging circular apertures 93 pro vided in special links 65.

By reason of the various adjustments provided, accurate control may be had to produce a variety of designs. For example, the adjustment of the link 65 in the various openings 67, provides for regulating the extent of the in and out motion of the conveyor with respect to the cutter mechanism, whereby the depth of the cut may be carefully regulated. The position of the end of the conveyor passing around the roller 32 may be adjusted through the members 55' and 57, thus enabling the fur on the skins to be properly positioned with respect to the knives so that a more uniform and regular cut design may be obtained. By reason of the adjustment 70, 70, and 70", the extent of the in and out movement of the conveyor may be regulated and in addition this adjustment permits a change in position of the bearings supporting the shaft 61 in case it is desired to substitute a different gear 81 or cams 59, it being understood that a wide range in the speed of the conveyor may be obtained by substituting differently sized gears 81, while various movements of the conveyor with respect to the cutting mechanism may be obtained by substituting differently designed cams 59.. Compensation for changes in the size of the gear 81 may be provided through Jill the adrustment of the bearings 77 through the slot and bolt 76.

It is to be appreciated that the cams 59, as heretofore explained, may have a great many contours to produce different movements of the conveyor with respect to the knives and thus obtain a great variety of patterns or designs in the fur and also that instead of operating the conveyor continuously an intermittent movement thereof may be provided.

The relative motion of the conveyor and the knives is very slight since the fur is not very long. Furthermore, the travel of the conveyor about the rollers 31 and 32 during its in and out bodily movement together with the rise of the cams 59 are so adjusted with respect to each other as to obtain a shearing of the fur to produce the cesign shown in Fig. 7. Obviously, however, by varying these two factors as well as the speed of the conveyor and the extent of the bodily movement thereof distinctive designs differing from that shown in Fig. 7, and like those shown in Figs. 3, 4, 5, and other designs may be ob tained.

From the foregoing it will be readily understood that many designs in the shearing of fur may be attained by slight adjustments to the machine and that the machine is so constructed as to quickly and conveniently be arranged to cut the fur of a skin in any predetermined design and when so adjusted adapted to operate to produce such designs automatically.

The machines illustrated and described are, of course, merely illustrative of a practical embodiment of my invention, it being understood that in its broadest aspect the invention resides in the alteration of a skin to remove fur to produce a pleasing and novel appearance and that other modified machines may be employed without departing from the spirit and scope of the invention as defined in the appended claims.
