10 Claims.

My invention relates to fur treating machines and has particular reference to machines for preliminary treatment of furs prior to sewing them into garments.

One of the first steps in fur treatment consists in wetting the leather side of the furs, this operation being usually performed by hand, using wet sponges. The manual process is very slow, however, having also another disadvantage in that water from the sponges gets on the hair side of the furs, rendering further operations with the fur more difficult, especially for matching skins.

My invention has for its object to provide a machine in which pieces of fur or pelts can be.

automatically wetted on the leather side; then, after turning the pelts over, they can be automatically combed and brushed. My machine can be also provided with a separate attachment for rubbing and stretching the pelts after they have been wetted.

My invention is more fully described in the accompanying specification and drawings, in which:

Fig. 1 is a sectional elevational view of my machine showing a piece of fur placed in position to have its leather side wetted;

Fig. 2 is a similar sectional view showing a piece of fur placed in position for combing its hair, the wetting brush being covered by a shield;

Fig. 3 is a top plan view partly in section;

Fig. 4 is an end View partly in section;

Fig. 5 is a detail view of combs;

Fig. 6 is an end View of a fur rubbing attachment;

Fig. 7 is a fractional top plan view of the same; and

Figs. 8, 9, and are detail views of the modified ports and sleeves.

My fur treating machine consists of a base I preferably of a rectangular shape with four posts 2 at the corners. The posts support bars 3 (Figs. 3 and 4) at the front and at the rear to which are fastened as by welding the ends of relatively thin bars 4 extending from the front to the rear and having sharp teeth 5 at the top. Thin wires 6 are also stretched between the bars 4 suitably attached to the bars 3 at the level of the teeth 5, the bars and wires forming a grid for supporting a piece of fur or pelt I. If desired, additional thin wires may be provided extending transverseiy of the longitudinal wires 6. The fur is pressed against the wires and bars by a heavy plate 8 siidably fitted on the posts 2 and suspended on cables or wires 9 passing over pulleys Ill. The other ends of the wires are wound on pulleys H rotatively' mounted on a shaft l2, rotated by a motor !3. Magnetic clutches M are provided for connecting the pulleys H with the shaft. Handles l4 are 'also provided for manual operation of the cables. provided at the other end of the machine.

The leather side of the fur is wetted by a rotary brush it consisting of sections I5, l5, etc., mounted on a common shaft IS. The sections are separated by distances corresponding to the thickness of the bars 4. The shaft I6 is journaled in the end walls of a tank I! open at the top and adapted to hold water H or other liquid used for wetting thefur. The brush is rotated by a motor is mounted on the extension of the bottom of the tank, the rotation being transmitted by a belt or chain 20 and pulleys 2i and 22. The motor is also connected bya belt or chain 23 with a pulley 24 on one of the wheels 25 of the tank. The wheels are placed on guiding rails 25 extending longitudinally of the machine.

The effective area covered by the supporting bars 4 and wires 6 is sufficiently large for a number of pelts treated simultaneously. Since some of the pelts may require less wetting than the others, a regulating device is provided in the form of Wiper bars 21, which may be of metal, rubber or other suitable material.

They are mounted on legs 28 pivoted on a shaft 29 and have handles 30 extending outside the tank. The wiper bars are retained in different positions by friction blocks 3! made of rubber or similar elastic material, engaging grooves .32 in the handles 30. By pushing'the handles inward, the wiper bars come'in contact with the bristles of the brushes, wiping off the excess of water. The wipingeifect can be regulated by the degree of advance of the wiper bars against the brushes. Additional wipers33 become effective when the handles 30 are moved sufficiently far inward.

The tank with the brushes is brought to the rear end of the machine before the fur is placed on the supporting grid. The motor l3 and magnetic clutches l4 are then energized, causing the plate 8 to descend and to press the fur against the grid. At the same time lugs 34 engage push buttons 35, closing circuit for the motor 19. The latter rotates the brushes and propels the tank to the front end of the machine, the brushes rubbing and wetting the leather side of the fur. At the end of the tank movement, the circuit for the motor brush and the tank to stop. At the same time the motor !3 is started'in the opposite direc-.

tion with the clutches l4 engaged, causing the plate 8 to be raised. The furs can be then removed from the grid. fl

For combining the hair, the fur is placed on the grid with the hair side down. The brushes are then covered by plates 35 mounted on legs 3! An identical arrangement is If! is interrupted, causing the bar 40. The plates are shown in the opened position in Fig. 1 and in the closed position in Fig. 2. The plates have slots 4I for straight brushes 42 slidably supported on the wall 43 of the tank, so that they can be moved upward for brushing the hair side of the fur when the rotary brush is covered with the plates 36.

Handles 44 are provided on the brushes 42 for moving them into an operative position. They are also guided by pins 45 sliding in slots 46 in the shanks of the brushes.

At the front Wall 41 of the tank there are provided combs 48 and 49 with their shanks 50 and slidably supported between rails 52 at the ends of the tank. The comb 49 has handles 53 passing through slots 54 in the outer wall 55, and the comb 48 has a handle 55 passing through a slot 56 in the outer wall and also through a corresponding slot in the outer comb 49. The combs are protected in their lowered position by a shield 50 hinged at 5|, so that it can be lowered and placed out of the way of the combs when the latter are raised, as shown in Fig. 2.

Due to the fact that pieces of fur cannot cover the entire surface of the pressure plate 8, the latter may be wetted in spots by the rotary brush during the wetting operation, and this moisture may be later transmitted to the hair of the next batch of furs. Meansis therefore provided for drying the under side of the plate 8 when it is raised. This may be accomplished by blowing hot air over the surface of the plate through pipes 51 from a blower 58, the air passing through an electric heater 59, after the plate 8 has been raised above the level of the blower ducts.

A wiper roll 60 may be also provided as shown in Fig. 2, the ends of the roll being guided between rails 6I at the sides of the machine. The roll is pulled from one end of the machine to the other by cables or cords 62 passing over sheaves 63 and wound on pulleys 64 on the shaft I6 and provided with magnetic clutches after the plate 8 has been raised above the rails 6|. The operation of the wiper roll as well as the blower may be made automatic, corresponding contacts being closed when the plate 8 is raised, the contacts being open again when the wiper completes one cycle of movement back and forth. It is understood that both devices, blower and wiper, can be used at the same time.

It should be noted that while the wires 6 and bars 4 can be spaced at short distances apart, so that they will support short pieces and corners of thefur, additional supporting wires 68 may be provided mounted transversely of the wires 6 on the ends of yokes formed of vertical rods 61 joined at the top with bars 68. The rods slide with certain friction in corresponding holes in a rectangular frame 09 mounted on the posts 2 and supported by bushings I9. The yokes formed by the rods and bars 68 can be therefore raised or lowered individually and will remain in any such position. The yokes are raised by a frame II sliding over the posts 2 and suspended on cords or cables I3 passing over pulleys I2 and wound on pulleys I4 on the shaft I6, the connection between the latter'and the pulleys 14 being effected by magnetic clutches. The yokes are lowered by the pressure from an upper frame I6 sliding on the posts 2 and suspended on cords or cables 1! passing over pulleys I8 and wound on pulleys I9 on the shaft I6, the pulleys I9 having magnetic bars 4 if there is a slight difference in length between the rods 61.

The wires 66 are used for supporting a piece of fur during the process of wetting its leather side, as shown in Fig. 1. The wires 66 and yokes may be omitted, however, if the stationary wires 6 are closely spaced and even reinforced by cross wires (not shown).

My machine can also be used for rubbing and stretching the fur, so as to remove folds and wrinkles. Levers 82 (Fig. 1) are provided for this purpose pivoted at 83 to the posts 31 and having a rounded bar 84 extending between the adjacent bars 4. The bar 84 is pressed against the leather side of the fur, while the other leg of the lever slides over corrugations 85 on the base I.

The bar rubs 0r irons the fur with jerking movements, similar to the movement when the fur is rubbed by hand. Sheet metal protectors 86 are clamped on the teeth 5 between the bars 84, so as to allow stretching of the fur on the bars 4. A spring 81 keeps the lever pressed against the corrugations 85.

The rubbing of the fur 'I can be also made on an attachment to my machine shown in Figs. 6 and '7. The base I may be an extension of the base I and the motor I3 may be the same motor I3, which operates the other part of the machine. A vertical board 88 is provided for supporting a piece of fur 'I, which is clamped at the top with a heavy bar 89 having a rubber strip 90 and suitably guidedat the ends. The fur is rubbed by hollow bars 9! supported on levers 92 pivoted at 93 on brackets 94 extending from sleeve 95 sliding on four posts 96. The outer lu s 91 of the levers slide over corrugations 98 on the posts. Pressure of springs 99 urging the brackets 94 and the bars is regulated by adjusting screws I00. The sleeves 95 are joined by bars IOI and are attached to cords or chains I02 passing over pulleys I03 and I94 on shafts I05 journaled in brackets I06 and I01 on the posts 96. The shafts are rotated by the motor I3 through gears I08 and I09, the shafts I05 being connected by a cord I02 on pulleys H0.

The motor may be provided with separate speed control for raising and lowering the sleeves. Hot

air is admitted into the bars 9| through flexible tubes I I I from the blower 59, Fig. 1, the air emerging through small holes IIZ. Additional cloth rolls II3 may be provided for wiping the board 88 when the fur is removed, the rolls having fabric flaps attached to the sides of the bars 9|.

The operation of the motor is preferably so arranged that the bars 9| move downward when the fur is clamped by the bar 89 and close corresponding contacts, the motor being automatically stopped by another set of contacts when the bars complete their downward travel.

The motor is reversed by a hand switch for moving the bars upward, a hot air blast being at the same time started for drying the board 88.

Several parallel boards 88 may be provided for simultaneous treatment of a number of pelts.

The sleeves 95 may be provided with levers 92 at both sides, the brackets I06 and I01 being then mounted on the end sides of the posts 96.

The device can be also used for ironing seams in a piece of fur prepared for making a coat. To make the seams smooth, they must be rubbed with a steady motion of the ironing bars 9|. A modified arrangement for this purpose is shown in Fig. 8.. The posts 3' are smooth and have bars II4 placed at their sides and attached by screws H5, passirg through holes in sleeves 95'. The bars H4 have teeth 98, the lugs 91 bein sufliciently wide partly to cover both the posts and bars I I4. Holes I I6 for the screws are made wide in horizontal direction, so that the bars H4 can be clamped either in the operative position with the teeth extending above the post H3 as shown in Fig. 8, or they can be withdrawn, in which case the lugs 91 will slide over the smooth surface of the posts H3.

My machine can be used simultaneously for different operations in different sections, as, for instance, one section can be used for wetting furs, another for combing and wetting at the same time, the third for combing only, the fourth for moderate wetting, using wiper bars 21.
