12 Claims. (01. 69-24) rapidly rotating heated drum which may optionally be provided with brushing elements. Such machines are quite eilicient in ironing and brushing iur pelts andunflnished or unlined fur garments. They have, however, not performed very efficiently in the conditioning of large fur pieces because the fur conditioning drum contracted the fur piece only over a relatively small area. Certain modifications in the basic prior art design have been carried out to cure this disadvantage. these modifications generally taking the form of the employment of a pair of feeding rollers spaced with regard to the fur conditioning drum, one of those rollers moving more rapidly than the other so as to tension the fur piece and thus cause it to contact the fur conditioning drum over a substantial area. Such a machine is illustrated in my Patent No. 1,874,273 of August 30, 1932. However, that modification has the marked disadvantage that a considerable strain is exerted on the nonfurry surface of the fur piece. This is not objecwhen it is desired to recondition an already lined garment machines of the type shown in my Patent No. 1,874,273 are quite inefiective, since the tensioning eflfect exerted by the two rollers rotated at differing speeds does not tension the fur but instead acts to rip and tear the fragile lining which makes contact with those rollers. Another disadvantage of the above type of improved fur conditioning machine is that the force which presses the fur piece against the conditioning drum is limited and is to a large extent uncontrollable. The importance of this drawback is apparent when it is realized that the brushing and ironin effect exerted by the conditioning drum is to a large extent dependent upon the force with which the fur piece is pressed thereagainst. Moreover, different furs will require different pressures and two furs of the same type but of difierent condition insofar as wear is concerned will require diflerent optimum pressures. Consequently, the lack of acc rate pressure control inherent in the prior art machines presented a considerable problem.

From a practical point of view, the size of the fur conditioning drums are limited both by economic and mechanical factors and as a resultthe drums are in almost all cases of a size such that,

dual fur pelts, they are considerably smaller than a complete fur. garment, such as a coat. This has made for some difliculty when finished garments are to be reconditioned. A full size fur coat is exceedingly awkward to work with and is often quite heavy and bulky. Only a small part thereof can be worked on at any one time by the fur condi-' tioning drum and in the past the remainder of the garment has either been permitted to dangle from themachine or has caused great inconvenience to the operator, who must hold it away from the floor of the plant and the greasy and dirty moving parts of the fur conditioning machine. As a result, the conditioning of complete fur garments has not only been hazardous to the garments but has been extremely time consuming and very trying to the operator of the machine.

It is the prime object of the present invention to devise a fur conditioning machine so constructed as to be particularly adapted for use with ilnished fur garments, including those garments which are considerably larger than the size of the fur conditioning drum.

A further prime object of the present invention is to devise a fur conditioning machine the efliciency of which is materially increased by causing the fur body to contact the fur conditioning drum over a substantial area thereof while at the same time minimizing undesired strains on the fur.

Yet another object of the present invention is to devise such a machine in which the pressure of the fur piece against the conditioning drum may be closely controlled, thus permitting the same machine to be used for varying ypes of furs or for furs of the same type in varying conditions of wear with the greatest efliciency.

Yet another object of the present invention is to devise a fur conditioning machine the conditioning parts of which are of conventional size, a work supporting table or size suflicient to support a finished fur piece such as a coat being employed in conjunction therewith.

Yet another object of the present invention is to devise such a machine employing an endless belt for conveying the fur piece past and over the fur conditioning drum, said belt and its guides being so arranged that thefur piece on the belt is caused to be pressed against the fur conditioning drum and to conform thereto over a substantial area thereof.

To the accomplishment of the foregoing objects and such other objects as may hereinafter appear, the present invention relates to the construction of a fur conditioning machine as dewhile they are generally larger than some indivi- 5 dried in the appended claims and as set forth Fig. 3 is a schematic side view showing the moving parts in their inoperative position; and Fig. 4 is a view similar to Fig. 3 showing the moving parts in their operative position when a fur piece is being worked upon.

Broadly considered, the fur conditioning machine of the present invention comprises a frame generally designated A on which a fur conditioning member in the form of a conventional drum, generally designated B, is rotatably mounted. Fur feeding mechanism generally designated G is provided, this mechanism including a carriage D articulately mounted on the frame A so a to be movable toward and away from the drum B, and a pair of guides E and E mounted on the carriage D and so positioned that when the carriage D is moved toward the drum B the guides E'and E will both tend to contact the outer surface of the drum B at separated points. An endless belt F is moved over the guides E and E and is adapted to receive the fur piece 2 and convey the same over the drum B, which is normally rotated at a greater peripheral speed than the fur 2 moves thereover, thus achieving the desired conditioning action. A means generally designated G is provided for moving the guides E and E toward the drum-B, the connections between the means G and the guides E and E being such that the operator, by controlling the force applied to the means G, will-in turn control the pressure with which the fur-piece 2 is pressed against the conditioning drum B. In order to facilitate working with large objects,a work supporting table H is employed, that table having an aperture J therein through which the guides E and E and that portion of the endless belt F which moves thereover are passable.

The frame A includes bottom plates 4 and guidesE and E in the form of rollers 34. A bracket 35 is mounted on each of the members 22 at a point downwardly spaced with respect to the forked arms ll and 32 and in this bracket a third guide in the form of roller 36 is journalled, the roller being faston shaft ll which projects out through one of the brackets II and is joined, by means of the universal connection generally designated 42, to a speed reduction ar assembiy 44 which is in turn connected, by means of belt 46 and

pulleys

46 and 56, to motor 52. Each of the brackets 38 is provided with a finger SI and a screw 66 having a knurled head is is threadable therethrough, the tip of the screw engaging a lug 6| on the carriage member 22. The endless belt F is arranged to fit between the carriage members 22 and to pass over the three guides defined by the pair of rollers 34 and the third roller 36. The roller 36 is rotated by the motor 52 and causes the belt F to move over its guides. In order to ensure that adequate frictional contact exists between the belt F and the driving roller 36, and in order to accommodate for any stretching or slack which may develop U-shaped side pieces 6 each having a short vertical arm 8 and along and inwardly inclined arm III, the drum B being rotatably mounted near the extremity of the arm Hi. This drum may take the conventional form of a hollow body having a cylindrical external fur conditioning surface I! provided with inclined deep notches or depressions M. The drum B is heated in conventional manner and as a result the cylindrical surface l2 exerts a pressing action upon the fur piece 2. The notches H, by agitating the fur fibres as the drum B is rotated, perform a brushing function. In some well known embodiments of the drum B, actual brushing elements in the,

form of bristles are applied to selected areas of the external surface l2 of the drum B. A motor I6 is mounted on the frame A and is operatively connected to the drum B to rotate the same by means of connections It. The motor l6 may also operate a blower, the duct of which is illustrated at 20, for assisting in cleaning of the fur piece 2 as it is worked upon by the conditioning drum B.

The carriage D is here illustrated in the form of a pair of spaced members 22 each having a lower portion 24 pivctally mounted on shaft 26 which is journalled in the frame side pieces 6. It will be noted that the pivotal axis defined by the shaft 26 is'positioned on the right hand side of the drum B as viewed in Fig. 1.

The other extremity of each of the members 22 is provided with a pair of fixed forked

arms

30 and 32 at the ends of which are journalled the in the belt F, the driving roller 33 is adjustably mounted on the carriage member 22 by means of the cooperation between the screws 56 and the lugs 60 en the carriage member 22. It will be apparent from an examination of, Figs. 3 and 4 that as the screws 66 are moved through the fingers 54, the driving roller 36 will pivot away from the rollers 24 and thus take up any slack in the endless belt F.

It will be noted that the bulk of the carriage members 22 themselves, as well as the various apparatus secured thereto, are all positioned to the left of the axis of rotation of the drum B and to the left of the shaft 26 which defines the axis of rotation of the carriage members 22. Consequently, the fur feeding mechanism C which is made up of the carriage D, the guides E and E, and the endless belt F, will normally assume the inoperative position shown in Figs. 1. 2 and 3 in which the carriage members 22 have rotated in a counter-clockwise direction as far as they are permitted to do so. As a result, the guides E and E and the endless belt F are spaced a considerable distance from the drum B.

The means G is provided for moving the fur feeding mechanism C, and in particular the guides E and E, toward and into contact with the drum B. The means G comprises a foot operated treadle 62 secured to levers 64 pivotally mounted between the upstanding portions 66 of the frame A. Links 66 are pivotally connected both to the levers 64 and the carriage members 22. Hence, a positive connection exists between the treadle 62 and the carriage member 22, the connection being such that depression of the treadle 62 from its position shown in Fig. 3 to that shown in Fig. 4 will cause the carriage members 22 to pivot against their own weight in aclockwise direction about the shaft 26, thus bringing the endless belt F, as it passes oeer the nuts "so as to permit the fur feeding mechathe connection between the treadle 62 and the guides E and E, the pressure exerted by said guides E and E against the drum B will be directly controlled by the pressure exerted on the treadle 82.

Mounted on the frame A by means of arms I8 is the work supporting table H, that table having a horizontal work supporting surface 80 positloned in front of the drum B and a downwardly inclined work supporting surface 82 also positioned in front of the drum .B and dropping down therebelow. In its preferred form, the downwardly inclined surface 82 is interposed between the drum B and the guides E and E when those guides are in their normal position illustrated in Fig. 3. The downwardly inclined surface 82 is provided with an aperture'J, clearly shown in Fig. 2 as being of cut out shape, of such a size and particularly of such a-width that the guides E and E and the endless belt F passable thereover are freely movable therethrough from their normal inoperative position shown in Fig. 3 to their operative position shown in Fig. 4. Both the horizontal surface 88 and the downwardly inclined surface 82 are of a width greatly exceeding the width of the belt- F and of the drum B so that a large coat may be supported on the table H while only a small proportion of its fur surface may. be worked upon. Furthermore, because of the inclination of the surface 82, the portion of the fur body 2 notbeing directly acted upon by the drum B will feed downwardly by gravity in a more or less controlled manner, thus facilitating the feeding of that portion of the fur body pressed and into contact with the fur conditioning drum B. If no inclined surface be used to support the fur body, then all of its weight would act to pull the fur body through the machine at a more rapid rate than is proper, thus causing stretching of the garment and possible ripping of the lining where that lining makes contact with the endless belt F. By. inclining the surface 82 to a moderate degree, optimum conditions of feeding are ensured, the weight of the fur body assisting the operator and the machine without in any way placing a strain either upon the garment or the operator.

The operation of the machine will in the main be apparent from the above description. The fur piece 2 is placed upon the work supporting table H and that portion of the fur piece which is to be worked upon is positioned in line with the drum B. The remaining portions of the fur piece 2 are supported by the horizontal work supporting surface 88. The motors I 6 and 52 are started, the motor 18 rapidly rotating the drum B in' the direction indicated by the arrows 84 of Figs. 3 and 4 and the motor 52 rotating the driving roller 88 so as to cause the endless belt F to move more slowly over its guides E and E and 38 in the direction of the arrows 86 of Figs. 3 and 4. The operator then depresses the treadle 82, thus lifting the guides E and E through the aperture J above the inclined work supporting surface 82. The fur piece 2 is moved forwardly until its underside makes contact with the moving belt F, the belt thereafter pulling the fur piece 2 along. Continued depression of the treadle 82 causes the belt F and the guides E and E! to force the fur piece-2 into contact with the rapidly revolvin heated drum B. B controlling the amount of force exerted upon the treadle 82, the pressure exerted upon the fur piece 2 urging it into contact with the drum B can be controlled. By reason of the fact that the guides E and E are spaced one from the other so as to make contact with the cylin drical surface l2 of the drum B at spaced points, thefur piece 2 is caused to conform to the periphery l2 of the drum B over a substantial area thereof, the belt F stretching sufliciently to permit such conformance of shape to take place. (Compare the straightness of the belt F between the guides E and E in Fig, 3 with the curvature of the same belt F in Fig. 4.) As a result, the drumB acts upon a given portion of the fur piece 2 for an appreciable period of time, thus increasing the efliciency'of the machine either by permitting an increased speed of passage of the fur piece 2 through the machine, thus increasing the capacity of the machine, or by providing more conditioning action for a given speed of passage of the fur 2. through the machine. During the time that the fur piece 2 is being moved through the machine by the endless belt F, both hands of the operator are free for guiding the fur piece 2 therethrough, and the operator is permitted to give his entire attention to the conditioning operation itself, since the remainder of the untreated portions of the fur piece 2 are supported by the work supporting table H. The operator can control the pressure between the fur piece 2 and the drum B and thus can modify that pressure as necessitated by the type of fur employed and the condition thereof. The operator .is assisted in the performance of this function by the counter-balancing springs I8 which aid himln overcoming the weight of the fur-feeding mechanism C and consequently reduce operator fatigue and render close pressure control feasible.

When one section of the fur piece 2 has been conditioned by the drum B, the treadle 62 is released by the operator and the weight of the fur feeding mechanism C, acting against the springs it, causes that mechanism automatically to once again assume its position of Fig. 3, the springs 10 cushioning the shock of the return to inoperative position. The guides E and E and the endless belt F passable thereover recede through the aperture J to a position below the inclined work supporting surface 82. Hence, without having to stop either of the motors it or 82, the fur piece 2 may be freely realigned or repositioned on the table H since the clearance between the table H and the drum B is quite adequate for that purpose and since the fur conveying endless belt F is positioned below the level of the table H. Once the fur piece 2 has been realigned, the operator need merely step once again upon the treadle 82 and repeat the conditioning operation.

By means of the above construction, an end-- less belt conveyor is provided which is se f-coeforming to the fur conditioning surface l2 of the the belt F to similarly conform to the fur condi-i ticning surface I2. This is accomplished without placing any excessive strains or tensions upon the undersurface of the fur piece 2. Consequer'lt-' ly, if the fur piece 2 takes the form of a finished coat with a lining, the machine of the present invention in no way tends to rip the lining or pull the lining from the coat, since the lining and the coat move together with one another and with the belt F, there being no slippage between any of the above elements.
