I. PRIMUS GARMENT STRIPPING MECHANISM Filed Jan. 3, 1946 5 sheet-sneet s v I[N VENTOR .frvmg Przmus BY ATTORNEY Patented Dec. 23, 1947 GARMENT STRIPPIN G MECHANISM Irving Prim-us, Forest Hills, N. Y., assignor to Isidor Gerber, Brooklyn, N. Y.

Application January 3, 1946, Serial No. 638,827 7 Claims. (01. 223-78) This invention relates to mechanism for stripping garments such as gloves or the like from a form on which the garment has been previously mounted, and for forwarding and pressing the garment.

In my copending application for patent for Garment stretching and pressing machine, filed on even date herewith, Serial No. 638,073, I have disclosed a machine for stretching the garment by clamping one end part thereof to a corresponding end of a heating form, then by means of an extensible member moving the other end part of the garment outwardly to accomplish the stretching, and after a given interval, retracting the member to permit part of the stretched garment to project freely beyond the form and thereby to strip the garment partially from the form.

The present invention contemplates the pro vision of simple means for insuring proper stripping of the garment, which is hereinafter referred to as a glove, from the form, said means comprising one or more yieldable plates carried against a face of the glove and moved along the form, thereby moving the glove off the form a sufficient distance to carry the freed end part of the glove into engagement with a pair of forwarding and pressing rolls having a belt interposed therebetween.

The invention further contemplates the provision of stripping means, self adjusting to variations in the thickness, size and position of the glove, and to the shape of the form whereby a limited area beyond the free finger tips on one side of the glove is engaged by a rotary yieldable member and the glove is moved by said member off th form a comparatively short distance but enough to carry it into the bight of a pair of pressing and forwarding rolls.

The various objects of the invention will be clear from the description which follows and from the drawings, in which Fig. 1 is a side elevational view of the stripping means, showing the glove form and the glove to be stripped therefrom in dash-dot lines.

Fig. 2 is a front elevational view of the same.

Fig. 3 is a similar view, partly in section, of the main roll carrying the stripping plates.

Fig. 4 is a similar view of the same showing a modified form of the invention wherein a single stripper plate is employed.

Fig. 5 is a fragmentary cross sectional View of the stripping means showing the glove being stripped from its form.

In the practical embodiment of the invention shown by way of example, the glove ID has been brought by the form II on which it is mounted to a stripping position between the rolls I2 and I3 by suitable mechanism such as that shown in my said copending application or in Patent No. 2,286,059. In said position, the finger tips M or" the glove have been freed of the form, and the stripping operation has therefore been initiated. It then becomes necessary to complete the stripping, While if desired, additionally pressing the glove and advancing the pressed glove out of the machine.

The main roll I2 is continuously rotated by the bevel gear [5 (Figs. 1 and 2) on the drive shaft i6 driven from any suitable rotating part of the machine of which the stripping mechanism forms a part. Said gear l5 meshes with the bevel gear I "I on the main roll shaft l8, which shaft also carries the gear l9 meshing with the gear 2i) on the shaft 2| of the auxiliary roll it. The various gears are suitably proportioned to drive the rolls [2 and i3 continuously and at the same periph eral speeds. Suitable spaced frames as 22, 23 are provided to support the shaft It as well as to pivot the brackets 24 in which the shaft 2! is revolubly mounted. The spring 25' (Fig. 1) at one end of the bracket serves to urge the roll it toward its cooperating roll l2. Also supported by the brackets 24 is the shaft for the belt pulley The glove pressing and forwarding belt 21 passes around the pulley 25 as well as around the idler pulley 26 supported by the frames 22 and E3, the belt being interposed between the rolls 1? and i3 and engaging the lower part of the roll it and the upper part of theroll [3.

With the arrangement of the rolls l2 and i3 and the belt 27 above described, it will be seen that when the glove is moved a comp at y short distance downwardly off its form it, the free tips of the glove are inserted between the belt and the roll l2 (Fig. 5) and gripped therebetween. Rotation of the rolls l2 and i3 toward each other then serves to complete the stripping of the thus gripped glove, presses the glove between the rolls and then between the roll l2 and the belt 21 and also advances the glove, which finally drops off the belt at a point beyond the roll l2.

'Variations in the thicknesses of the gloves fed between the rolls are compensated for by the automatic yielding adjustment of the brackets 24, which move in a counterclockwisedirection as viewed in Fig. 1 under the influence of a thicker glove, and move clockwise to a sufficient extent to cause a thinner glove to be adequately gripped and stripped off the form,

For the purpose of feeding the glove to the rolls and belt, one or more stripper plates are provided. In the form of the invention shown in Figs. 2 and 3, the main roll I2 comprises end discs as 28, 29 carrying the cylindrical backing member 39 preferably of metal or other suitable rigid material, and the cylindrical outer member 3! which may be made of rubber, or textile material such as cloth, canvas, felt or the like yieldable or compressible material capable of providing a satisfactory glove gripping surface.

The members 30 and 3| are slotted to permit the stripping plates 32, 33, 34 and 35 to project normally from the interior of the roll outwardly through the slot 36 of the roll. To insure that the plates all act simultaneously to move the glove fingers ofi the form the same distance, thereby avoiding creasing or wrinkling of the glove, each of the plates is made of the proper length to press against only one of the fingers of the form. 'That is, the longest plate 35 coacts with the shortest form finger 31, 'the'shorter plate 54 coacts with the longer finger 38, the shortest plate 33 with the longest finger 39 and the plate 32 with the finger Ml. Each of the plates terminates in an enlarged portion '41 loosely mounted on a rod as 12 arranged within the roll l2 and supported as by the brackets 43 (Fig. suitably secured to the inner face of the backing member 30.

To urge the plates to rotatein counter-clockwise direction as viewed in Fig. 5, ;a tension spring as 44 is secured at one end to the extension 45 of the enlargement 4| and at its other end to a part of the backing member 30 beyond the slot 36. Said slot is of such width as to permit the outer end 46 of each plate to be retracted within the roll as the plate passes the glove form-and engages the stripped glove on the belt 21, the slot also permitting the plate to be fully extended into spring-pressed contact with the glove while the glove is on the form.

It will now be understood thatduring about half of the revolution of the slot 36 of the main roll, the stripping plates are positioned with the ends 45 thereof projecting out of the slot 36, under the influence of the springs M. As the plates approach the form and come into contact with the glove thereon, the plates begin to recede into the slot against the action of the springs. On further rotation of the roll 12, the plates are drawn bodily along the form, carrying with them the glove fingers, the plates being suiiiciently roughened or knurled on their outer faces to prevent slippage between them and the glove. Only a slight movement 'of the glove is needed to carry the finger tips thereof into the bight of the belt and the roll 2, whereafter the rolls and the belt complete the stripping action at the same time that the plates recede completely within the slot 3%,said plates remaining in contact with the fingers of the glove and pressing the glove against the belt as the rotation of the rolls continues. As the roll rotates the plates pass the last point of contact between the main roll and the belt, the springs become operative again to project the end portions of *the :plates out of the slot in the roll, ready to repeat the stripping operation.

In the form of the invention shown in Fig. 4, a single plate 50 replaces the four individual plates. Preferably, the outermost edge 5i of said plate is inclined to arrange the widest part 52 thereof at the shortest form finger 3'5 so that all of the form fingers may be engaged at about the same distance from the respective tips thereof, thereby to avoid possibility of resistance to the stripping action and consequent wrinkling or creasing of the glove. The slot 53 in the main roll !2 is similarly inclined, but since only one of the plates is employed in this form of the invention, only two springs 54 take the place of the individual springs 44 for projecting and retracting the plate. I

It will be seen that I have provided simple and efficient self adjusting stripping means to strip the glove or other garment partially from the "form by a sort of wiping stroke and that the stripping is positively and effectively completed by the same means which serves to press the giove and to advance it out of the machine.

In order that the mechanism may strip a right hand glove as well as a left hand one or other garment having a laterally protruding part such as a thumb, the guard cover 55 (Fig. l) for the roll it is suitably secured at one of its edges to the brackets 24 as at 56, the other edge 51 of the guard cover being suitably shaped to engage the tip of the thumb and to guide it against the form so that the thumb tip enters the bight of the rolls flat and undistorted. In the case of a left hand glove, the larger diameter of the roll 52 insures the proper flattening of the thumb against the form, since owing to the acuteness of the angle made by the surface of the roll l2 with the face of the form, the loose thumb tip must move in the same direction as the surface of the roll and cannot move in the opposite direction to become creased or distorted.

While certain specific forms of the invention have been shown and described, various changes may obviously be made within the spirit of the invention defined in the appended claims.
