19 cla ms; (01. 223-57) This invention relates to glove-pressing and The invention further contemplates the provistretching machines, such as are disclosed in the sion ofta simplified, comparatively inexpensive prior patent to Isidor Gerber and myself, No. but efficient automatic machine for pressing and 2,148,403, dated February 21, 1939. I stretching gloves. -'5- In said patent is disclosed a machine in which The various objects of the invention Will be there are a number of glove-holding forms which clear fromthe description which follows and are intermittently'rotated so as to carry a form from the drawings, in which: with a glove thereon to a position adjacent a Fig. '1 is a'iside elevation of the machine. pair of revoluble glove-stripping rollers. The Fig. 2isa front elevation thereof. glove is partly stripped from the form by fingers Fig.'3;is a horizontal section thereof taken on 10 which are normally arranged within the form the line 3 3 of Fig. 1. but which are projected beyond the remainder. of Fig. 4 is a rear view of the glove form with the the form into the bight of the glove-stripping cover thereof removed to show the interior of the rollers, which complete the stripping and also heating'chamber. press the glove. Fig; 5 is avertical section of the form. 15 I The form of said prior patent is illustratedas Fig. 6 isa side elevation of the thumb-positionhaving a thumb on which the glove thumb is lng means and :of the operating mechanism mounted. Means are also illustrated therein for therefor. moving the glove thumb toward the glove palm Fig.7 is a. vertical section of the mutilated to insure the proper entrance of the glove thumb pressing and: stripping rollers showing, the posi- 20 between the rollers. One of the rollers is'also tionof the form and the partly stripped glove illustrated as movable bodily relatively to the carriedcthereby between'the rollers and at the otheri h the form fingers are pushed therebemutilated part of the rollers just prior to the tween l stripping operation of the stripping rollers.

I have found that the provision of a thumb In the practical embodiment of the invention 25 member on the form makes the form compara which I have shown'by way of example, the'matively expensive to construct and makes it difiichine consists, generally," of a number of glove cult to initiate the stripping of the glove from forms each provided with suitable heating means the form. I have also found that it is advisable to maintain the forms hot. The forms are interto use means more positive in action than that mittently rotated. While they are at rest, the 30 shown in said prior patent for moving theglove operator pulls a glove over the uppermost form thumb against the palm preparatory to-pressing so that the fingersof the glove are properly the glove. I have further found it to be unneces shaped and stretched on the corresponding finsary to provide relative bodily movement of the gers of the formfwhilethe glove, thumb hangs pressing rollers, since the stripping function of loosely. Theglov'e is maintained in its stretched the rollers can be otherwise accomplished in an condition on the hot form for a sufficient time to inexpensive but eflicient manner. heat it thoroughly and toset it into itsproper This invention therefore contemplates the'proshape. While the operator is pulling a glove vision of a simplified glove-heating form devoid over the empty uppermost form, the fingertips 40 of a thumb member and of comparatively simple of the heated glove on the lowermost form are 10 construction fromwhich the glove may be partly stripped therefrombythe operation 'of stripping stripped by the mechanism which initiates the members carriedby the form. At the same time, glove-stripping operation. the glove thumb is pressed against the glove The present invention further contemplates the palm by suitable positively acting mechanism.

provision of simple but positively acting means The fingertips and the thumb ofthe glove are 45 for moving the thumb of the glove tightly against thereby inserted at the mutilated parts of and the palm to insure theentrance of the thumb bebetween a pair ofimutilated stripping rollers; As tween the pressing rollers in proper position for the rollers rotate, the unmutilated parts thereof the correct pressing thereof. grip the leading tips of the glove and strip it The invention further contemplates the provicompletely from the form-with the thumb there- 50 sion of pressing and stripping rollers between of in proper position for pressing regardless of which the glove maybe arranged in position for the right-hand or left-hand character of the stripping the glove from the form without any glove. 7 The stripping rollers also press the glove necessity for moving either oftheserollers toward and advance it into the bight of a second pair of .theothen r I stretching roller'sw'hich rotate at a higher surface speed than that of the stripping rollers. The thus pressed and stretched glove is advanced by the stretching rollers on to a moving belt for discharge from the machine.

The form I0, as best seen in Figs. 4 and 5, comprises a single piece of metal having four fingers ll, 'l2, l3 and I4 of the proper relative lengths and the preferably flat respective front and rear faces l5 and I6. An opening I! is made in the rear face l6, said opening communicating with the hollow compartment I8 arranged at oradjacent to the palm of the form. The cover l9 provided with the slot 20 covers the opening I? and is removably securedto the form and closes the compartment l8 when the form is in operation. Within said compartment is ar ranged the electrically operated heating element 2| continuously supplied with current through the

wires

22, 23 by means of a suitable commutator 24 such as is disclosed in said prior Pat ent No. 2,148,403.

Extending longitudinally through each of the fingers is an opening or bore 25 communicating with the interior of the compartment I8. A stripping rod as 26 is arranged in each of the bores 25 and is longitudinally reciprocable therein to project the end portion 21 thereof outwardly beyond the form and thereby to strip the fingertips of the glove from the form. The inner ends of the rods 26 are connected. by a transversely arranged connecting member 28 located in the compartment l8. From the member 28 extends the member 29 which carries the pin 38 passing through the slot 20 of the cover IS. The roller 3| outside of the form and revolubly mounted on the pin 30 is engaged at the proper time by means later to be described, which moves the pin in the slot 20 and thereby projects the rods 26 beyond the form against the action of the spring 45 to initiate the stripping of the glove. a

Each of the rods 26 is convexly rounded at its outer end to form a continuation of the convex outer surface of the tip of the form finger in which it is mounted, when the rod is in its retracted position. The surfaces I5 and I6 of the form It) being preferably flat, a right-hand or left-hand glove may readily be stretched thereon. In the case of a right-hand glove, the thumb of the glove will be adjacent the surface IE, but in a left hand glove, the thumb will be adjacent the surface l5.

A plurality of forms II) project radially from and are mounted on the hub 32 of the form operating shaft 33, which is intermittently rotated by the Geneva wheel 34 on said shaft 33, by means of the Geneva disc 35 and the pin 36 carried thereby. The disc 35 is mounted on the shaft 37 which also carries the bevel gear 38 meshing with the bevel gear 38 on the shaft 46. Said shaft 46 is the driving shaft of a reduction gear unit as 4|, the driven shaft of which carries the pulley 42, driven by a suitable belt from the motor pulley 43 on the electric motor 44. Continuous rotation of the motor rotates the forms intermittently about the shaft 33. The shaft of the reduction gear unit also carries a sprocket wheel 45 which operates the chain 46.

For operating the rods 26 through the roller 3|, said roller is engaged by the grooved member 41 at the end of the bell crank lever 48 when the form is at rest in its lowermost position. The groove in the member 41 being arcuate, the roller 3| enters said groove (see Figs. 1

and 2) as the form reaches its lowermost posi* tion. The lever 48 is pivoted as at 49 to a fixed part of the machine, such as the frame, the arm 58 of the lever engaging the cam surface of the cam 5| on the cam shaft 52. The chain 46 continuously rotates the cam shaft and cam 5| through the sprocket wheel 53 on the cam shaft. After the roller 3| has entered the groove of the member 41 and while the form In is at rest, the high part ofthe cam 5| engages the arm of the bell crank' lever 48 and rocks said lever in a counter-clockwise direction as viewed in Fig. 2 thereby lowering the grooved member 41 together with the roller 3| and projecting the rods 26 out beyond the fingertips of the form to partially strip the glove therefrom. On further rotation of the cam, the lever 48 is moved by the spring 54 in a clockwise direction and the rods 26 retracted but the glove remains partially stripped from the form.

In order to complete the stripping of the glove, a pairof continuously rotating

rollers

55 and 56 are provided. Said rollers being similar to each other, a description of one will suffice for both. Each of said rollers consist of an incomplete hollow cylinder as 51 provided with a longitudinal opening as 58 in the surface thereof, said opening being of less length than that of the cylinder and of less width than the circumference of the cylinder (see Fig. '7). The cylinder is covered by flexible fabric sheet 59 which is stretched across the opening. A suitable disc 60 terminating in a hub 6| is inserted at each end of the member 51 whereby the roller may be mounted on its operating shaft. The roller 55 is mounted on the shaft 62, while the roller 56 is similarly mounted on the shaft 63 in such a manner that as the rollers rotate, the openings 58 come together or reach a position adjacent each other at the time that the form l8 reaches its lowermost position and the glove is partially stripped therefrom by the rods 26. While the sheet 59 is unsupported at the opening 58, said sheet acts as an adequate cover for the opening, to prevent any possibility of the glove entering the inside of the roller or of lint, dust and foreign matter reaching the inside of the roller and getting into the bearings thereof.

It will be seen from Fig. 7 that the rods 26 push the fingertips of the glove off the form and partway into the openings 58 in position to be gripped by the unmutilated parts of the

rollers

55 and 56 on the continued rotation of said rollers from the position of Fig. 7. Continuous rotation of the rollers is effected by means of the chain 46, engaging the

sprocket Wheels

64 and 65 on the

shafts

62 and 63, respectively. It will further be understood that the rollers and sprocket wheels are made of the proper size to rotate one revolution during each intermittent movement of the forms. If desired, one of the rollers as 55 may be mounted in a spring-pressed bearing as 66 thereby permitting the

rollers

55 and 56 to move slightly toward and from each other for the purpose of compensating for various thicknesses of the glove passing therebetween in a manner which is well understood in the art. By providing a fabric or the like friction covering for the rollers, a suitable frictional contact between the roller and the glove is provided, thereby insuring against relative slippage therebetween and preventing the. rollers from giving the surface of the glove an undesirable shine.

It has beenpreviously indicated that the thumb of the glove may be arranged adjacent one surface or the opposite surface of the glove form, depending on whether the glove is a right-hand glove or a left-hand glove. I have, therefore, provided means capable of acting on the thumb to press it against the palm and to insure its entrance between the rollers 55. and 56 in the proper position for pressing, regardless of the size of the form on which the thumb is arranged. Said means. comprises the thumb-moving members 6'5 and 5B, which are arranged to assume positions on opposite sides of the form I when the form is moved in its lowermost position.

Means are also provided for operating said members to move toward and from each other alternately to engage and press the thumb against the palm of the glove into its proper folded position regardless of the position in which the thumb may be first disposed when theglove is manually put on the form. The member Bl is pivoted as at 69 to the crank 10, being spring-pulled about its pivot by means of the spring H into a position in which the part l2 thereof engages the stop member won the crank. Said crank is pivotally mounted as at M on the bracket for oscillatory movement which is imparted to the crank by means of a second crank it on the pivot shaft M. The crank 15 is in turn operatedby the link Tl connected to one end as 18 of the crank lever '19. Said crank lever is pivotally mounted at its lower end as at and is, spring-pulled as by the spring 8! in the proper direction to cause the roller 82 thereof to engage the cam 83 on the shaft 63.

It will be seen that during the rotation of said shaft 63, the cam fiiiswings the crank lever 19 about its pivot 80 thereby moving the link H in the proper direction longitudinally to oscillate the crank 16, the shaft 'M the crank 10 and the. member 61. The member 58 is similarly pivoted to the bell crank lever 84 as at 85 and is similarly spring-pulled by the spring 86 against the stop 87. The arm 88. of the bell crank lever 84, however, projects in a direction substantially opposite to thatin which the crank vH5 projects and is operated by the link 1'! so that the members 6.! and 68 move toward and fromeach other alternately. At its inner end, each of the members 6'! and 6.8, is, provided with an outwardly directed extension 89 of suflicient length to extend past theopening 58 of the corresponding

rollers

55 and 56 when the members 6] and 68 have been moved downwardly into their lowermost positions. Said extensions 89-, prevent the thumb-moving member from being; drawn in between the rollers. It will be understood that the thumb-moving members are of sufllcient length and are so spaced as to engage the thumb while the form is at rest in its lowermost position. As the

plate members

61 and 68 oscillate toward the form, one of said members engages the thumb and moves it toward the form. The member carries the thumb downwardly and inwardly to press it against the palm of the'glove and to fold it flat regardless of how the thumb is arranged or on which side of the form it is. The membersmove downwardly until the extensions 89 thereof rest on the rollers. In this position, the thumb is properly flattened against the palm of the glove. The rods 26 are then operated to strip the fingertips of the glove from the form. This operation moves the glove downwardly, the thumb being'further pressedby the plate member, which remains in position until the. unmutilated parts of'the rollers engage the glove and drawtheglove off the form. where.-

after the cam 83 becomes effective to swing the platesmembers back to the full line positions of Fig.

Themembers 61 and 68 being pivoted and spring-pulled, irregularities in the position of the thumband consequent differences in the effective thicknesses of different gloves are compen- 1 sated for by the yielding of the plate members.

It will be understood, however, that the members act positively first to fold and press the thumb against. the palm, then to maintain the thumb folded and finally to assist. in pressing the thumb as the glove is completely stripped from the form. The

rollers

55 and 56 complete the stripping. of the. glove and the pressing of the glove including the thumb thereof.

. After the glove has been stripped from the form and the thumb pressed against the palm thereof. by the stripping

andpressing rollers

55 and 56, the glove is advanced by said rollers to the stretching rollers 90 and 9!. Said rollers rotate. at a slightly greater surface speed than the rollersfiii and 56 and thereby slightly stretch the glove as it passes therebetween in a manner which is fully described in said prior Patent .No. 2,1 48, 1 03, and a description of which need not be repeated. After passing between the stretching rollers, the glove is advanced by the conveyor belt 92, to a' position where the pressed glove may be removed by an operator.

It will be seen that I have provided a heating glove form of simple and comparatively inexpensive construction and a machine for stripping gloves therefrom and positioningthethumb oi the glove positively and-for pressing the glove including the thumb, said machine being. of simplified construction including a simple single chain drive, for the rotating parts, vIt will also. be seenthat by the provision of mutilated glovestripping rollers, I dispense with the necessity of moving the rollers apart to position them forthe glove stripping operation, and that I have pro vided a simple machine well designed for practical use.
