16 Claims. 1

This invention relates to a glove turning inachine. i

The chief object of this "invention is to turn gloves more expeditiously and automatically by a cyclically operable machine of extremely simple character.

Another object of the invention is to provide a machine which may be supplied with gloves to be turned and after application, which may be manual, the gloves are automatically turned and then stripped or discharged from the machine.

In machines of this general type it heretofore has been the practice to provide an intermittently rotatable element with a plurality of units, each adapted to take a sewed glove at one station, automatically turn the sewed fingers inside out or to the normal position, depending upon whether the finger sewing is to be disposed inwardly or outwardly, and then remove the turned glove.

This practice is also herein adhered to.

The chief feature of the present invention resides in the simplification of such turning device.

Another feature of the invention resides in the hydraulic or pneumatic type of powerv employed and its'control, the former being utilized with water, oil or the like and the latter being utilized with compressed air or the like.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

Fig. 11 is a perspective view of a portion of a modified form of the invention, the modification being directed more particularly to the power for indexing the finger drum. n

Fig. 12 is a plan view of a portion of a modified form of the invention on a slightly larger scale than Fig. 11, and more particularly of the driving end of said drum and its actuator.

Fig. 13 is a central sectional view of one of the indexing pins taken on line Iii-43 of Fig. 11 in the direction of the arrows.

Fig. 14 is a central sectional view of the power cushioning mechanism taken on line i'i|4 of Fig. 11 in the direction of the arrows.

In the drawings there is illustrated an embodiment of the invention selected for exemplification thereof. In Fig. 1, l I indicates conventional leg structures that at the upper ends are suitably secured to the bed or base plate [2.

The latter at one end is notched out as indicated IE3. Adjacent thereto and at the ends I4 of said plate are the uprights or brackets I5 which rotatably support a drum structure indicated generally by numeral [6 in Fig. 1.

Frojecting radially therefrom are the finger groups, herein four in number, disposed at degrees. Each group or unit comprises four finger tubes designated generally by the numeral ll. These tubes in drum rotation clear the base l2 by reason of notch it being provided therein.

At the opposite .end of the machine base H supports bracket l8. Brackets l5 and brackets it have inwardly directed aligned sockets l5a and Ida, see Fig. 2, and disposed therein are the guide and connecting members I9;

Reference will now be had to the left hand portions of Figs. 1 to 3 andFigs. 4 to 10, inclusive. As shown in the first mentioned figures the finger drum is socketed at 16a to take stems Ila having threaded connection with tubes 11. Each stem is locked to the drum as at 16b.

In Fig. 4 it will be observed that there is rotatably mounted in the brackets I5 a shaft 20 and that said shaft projects through the two brackets. Between the brackets said shaft mounts the drum l6 aforesaid. This drum includes a plate ZI that is provided with four quadrant disposed openings 22 successively engaged by a locking pin or plunger 23 normally constrained to locking position by the spring 24, the spring herein being nested in bore 23a of said pin and the pin in turn being slidably mounted in the bushing 25. The pin is longitudinally slotted as at 26 and disposed in said slot is the spring retainer 27. The locking pin is only capable of reciprocation toward and away from the drum.

The end of the shaft 20 has secured thereto a member 28 by means of nut 28a. The mechanism associated therewith may be enveloped by a detachable cover cap 29 if desired. Note that in Fig. 4 the locking pin is shown retracted. Fig. shows the locking pin projected and disposed in looking relation which holds the drum stationary during glove or finger turning operation hereinafter to be described.

As shown the member 28 is keyed at a to shaft 20. The shaft 20 has oscillatory movement only. The member 28 pivotally supports at 30 a member 31 which in effect is a cam and lock. Member 28 is cut away at 3la to accommodate this cam pawl. Plunger 32 is slidably supported by member 28 and is constrained by spring 33 to the position shown in Fig. 8. In the oscillation of said shaft 20 this pawl is effective upon plunger 23 to retract it and hold it retracted for an appreciable angular movement. reverses, the pawl accordingly is held out of looking engagement with the drum I6 so that the drum may be indexed a quarter turn at which time the pawl hold out arrangement is slidably disassociated so that the plunger, under the influence of its spring 24, moves toward the drum and engages in one of the sockets or seats 22' then registering therewith. This holdsthe drum stationary while the glove or finger turning operation is effected.

Reference will now be had more particularly to Figs. 4, 6, 7, 9 and 10 wherein the means for oscillating the shaft and the means for intermittently and step-by-step rotating the drum is effected. A cable 34, which may be of wire, is wound about a pulley 35 which pulley is mounted on said shaft 20 and clamped thereto at 36. This cable oscillates this pulley. The pulley or power drum is recessed as at 3511 forming a chamber wherein there is disposed a ratchet 31 that is rotatably mounted upon the shaft 20 and is rigidly secured as at 38 to a sleeve 39 disposed about shaft 20 and is rotatable in the right end bracket [5. A key 40 locks the sleeve 39 to the drum It so that the drum moves with the ratchet and the sleeve 39. The drum as shown at 4| and 42 includes bushings that rotatably support it upon the shaft 20. The cable drum 35 mounts a pawl 43 which herein is shown adapted for radial reciprocation being normally constrained toward the ratchet by the spring 44 retained as at 45, see Figs. 6 and 10.

Fig. 6 shows the parts at the end of the indexing travel of the finger drum. Fig. 10 shows the parts in the reverse rotation of shaft 20 and the ratcheting of the pawl. When the pawl 43 has been rotated, see Fig. 10, to the six oclock position, the pawl advances inwardly and engages the adjacent tooth face of the ratchet and upon the reverse cable travel, the ratchet and finger drum are advanced ninety degrees whereupon the plunger 23 seats in One of the drum sockets 22. Upon the movement of the parts aforesaid corresponding to drum 35 moving from Fig. 6 toward Fig. 10, it will be obvious that the drum l6 and ratchet 31 remain stationary. At the proper time the plunger 23 is retracted to release the flnger drum 16 so that it may be advanced or When the shaft 20 4 indexed ninety degrees by ratchet rotation. When the end of that travel is obtained the plunger 23 is released from its withdrawing force and again locks the finger drum I6 in indexed position.

Reference will now be had more particularly to Figs. 1 to 3 inclusive. The cable 34, see the right-hand end of the several fingers, is also mounted upon a pulley 45 carried by the bracket l8. The cable 34 also is provided with two adjustably mounted stop blocks or abutments 41. The cable 34 is slidable in a slot or opening 48 in a bracket or arm member 49 which is reciprocable toward and away from the drums. When the arm is moved to the left it leaves the right hand block 41 and travels toward the left hand block without effecting any cable movement. It then picks up the left hand block and causes the upper run of the cable to move toward the left and thus causes the drum to rotate in a coun-l terclockwise direction.

When the arm 49 is moved toward the position shown in Fig. 2 it initially leaves the left hand block 41 and travels toward the right hand block until it engages same. During this interval of arm travel no rotation of the cable drum is effected. Thereafter the arm 49 intercepts the right hand block 41 and moves both blocks and the cable to the right to the position shown in Figs. 2 and 3. This causes clockwise rotation of the drum 35 and this clockwise rotation of the drum corresponds to the indexing travel of the finger drum I6. In other words, when the arm 49 is moved toward the drums there is effected the ratcheting aforesaid. This ratcheting effects plunger pin withdrawal into the drum and seating of the pin in the drum and all, obviously, in timed relation to the operation justdescribed.

Slidably mounted upon guide I9 is the overhead carriage 50 which includes cylinder 5!. Disposed in same is a piston (not shown) connected to rod 52. This carries a stripper mechanism designated generally by numeral 53. Same also slides on guides 19.

Disposed below the plane of the guides is cylinder 54. A piston (not shown) therein is con nected to rod 55. The two rods are oppositely directed and the exposed end of rod is connected to arm 56 depending from the carriage 50.

Pressure fluid is alternately supplied to opposite ends of the cylinders and in timed relation. Thus pressure fluid supplied to the right hand end of cylinder 54 causes the piston therein, rod 55 and carriage 50 to advance toward the twb drums. Pressure fluid applied to the right end of cylinder 5| then projects rod 52 towards the drums.

Pressure fluid supplied to the opposite ends of these cylinders projects rod 55 and retracts rod 52. The operation is in timed relation and sequential. In place of fluid pressure for one way power application a spring may be employed. Such spring is compressed by fluid pressure in the initial travel of the piston and upon pressure fluid release, the compressed spring returns the piston to starting position.

Limit switches are provided to control solenoid operable valves to eifect pressure fluid supply and/or pressure fluid release. These valves are or may be arranged to waste the cylinder trapped fluid in reverse piston travel. Also each pressure fluid supply and/or waste line may include a manually adjustable valve to regulate the travel speed of theseveral rods and associated parts.

Herein carriage 50 mounts a transverse sup- 5. port 51 to which is adjustablysecured in spaced relation the members '58 which project toward the finger drum I5. These members or .plungers are tapered as shown at 58a and terminate in ball ends 59.

With the finger drum I stationary and a glove disposed upon tubes I! the advance of balls 59 into the endsof the tubes serves "to draw the glove fingers upon the portions 5.8a while in the tubes until each of the tube enclosed glove fingers is turned inside out. At this time the strippermechanism 53 is further advanced and the glove passes through the :same. Then the stripper is retracted to remove the glove from the tubes I I. Also the members 58-59 are retracted.

The freed glove then drops from the machine as shown at D in Fig. 1. A indicates the :glove as ainitially applied to same. B indicates an advanced position thereof while (1' indicates the finger turning position.

Since finger drum I6 is only indexed when the upper run of the cable is moved toward the right in Figs. 1 to 3 it will be obvious that this action only occurs when carriage 50 is retracted to the right, see same figures, by projection of rod 55, the locking 'pin 23 being previously retracted from a seat 22 as previously described.

There is provided.astationary'support 6U carrying upwardly extending members GI which are disposed between the 'four fingers for facilitating glove discharge. The stripper mechanism 53. comprises two opposed members 62 with upwardly directed support 63 and these are yieldingly contracted toward each other by means of a common tension spring 64. At the left end of the machine is a travel limit stop and quick action switch designated generally by the numeral 65. This switch is provided with a button 65w which is engageable by actuator 68 carried by the stripper mechanism, when that mechanism is projected to its extreme left-hand position. Under such circumstances the switch energizes a solenoid control valve. There is also provided a sta tionary switch structure 66 with button 66w which is engaged by member 69 in the travel of the carriage 50 and stripper 53 and that switch in turn controls the circuit to a solenoid in turn controlling a valve.

Then there is an additional control 61 having a button 61a that is engaged when the contactor 1!! reaches the extent of its forward travel. There is also a switch 680 having a button 68a engaged by contactor II when the piston rod 55 is fully projected or when the carriage 50 is fully projected to the right.

The sequence of the operation, is as follows: Fluid pressure is applied to cylinder 54 to advance the carriage 50 to. the left. This moves both stripper and fingers 58 to the left. When the piston rod 55 is sufficiently retracted switch 61 is actuated to supply pressure fluid to the right end of cylinder 5I. This causes piston rod 52 to be projected and this projection occurs to the extent determined until the stripper 53 (member 68) actuates the switch 65. When this switch is actuated, pressure fluid is reversely applied to cylinder 5| to retract the stripper with respect to cylinder 5|. When this has been effected the cam 59 is arranged to trip a switch, close a circuit controlling the supply of pressure fluid to the other end of the cylinder 54 to project its rod 55 and at the same time retract the carriage 50, cylinder 5| and stripper 53. This is continued until the cam II actuates the switch 681) to cut 6. ed the pressure supplyiand reconditionithe application of pressure to the'other end orthe cylinder 54. whereupon the 'cycle is repeated.

In this reciprocatory travel of the carriage 50 the arm 49. has been 'moved to and 'fro as previously described to efiect in timed relation the unlocking of the finger drum I6 and the indexing thereof occurs, to wit. station to station, step by step rotation as previously described.

IniFigs. ll to '14 there is illustrated a modified form of the invention, :same relating more particularly to the. finger *drumpower and indexing mechanism. Herein generally numerals of the onehundred series designateparts like or similar to those previously described and designated by numerals of the primary-series.

For-example in Fig. 11,*II6 indicates the finger drum rotatably mounted on shaft I20. Herein shaft I 20 mounts arm 1'35 pivotally connected at I35a to link 134a pivotally connected at I341: to actuating rod I34. The exposed end of sleeve I319 herein may include the internal pawl and ratchet connection but herein same is unnecessary. In the sleeve pockets 139b, closed by the retainers I3.9a,3there is the headed pin I13 normally constrained outwardly "by spring I44. Key I45 prevents pin rotation. The exposed end of pinv M3 is beveled as 'at I31.

There areas many pins as there are stations for the, drum. In link advance to the left, see Fig. 12. the arm I35 rotates counter clockwise, see Fig. 11, and engages face I31 of the uppermost pm 143 and forces same inwardly until the arm has, passed the pin whereupon the pin, due to spring 1M4, pops out. Upon reverse rotation of arm 135. same engages that pin and picks it up and the drum H6 for drum indexing.

Note that the-drumkis held stationary as before during the counterclockwise rotation of the arm, and in the clockwise rotation thereof the drum lock is initially released and held released until the drum has been indexed whereupon the drum lock is reestablished, all as previously describe and incident to oscillation of shaft I20.

The means for reciprocating rod I34 includes arm or bracket F49 carried by the upper carriage slidable on guides I ID. This bracket, see Fig. 14, has a hole I48. The rod I 34 slides through this hole. The rod may be suitably supported in. guide brackets as shown. The rod carries stops l4! which are threaded upon the rod and locked by nut I 41a.

Thus the rod I34 is alternately picked by arm 4 and reciprocated. As before there is a dwell period determined by the spacing between stops I41. To cushion the index stroke and rod pickup there is provided, see Fig. 14, a sleeve 148a inhole I48. Sleeve I 48b is hardened and is carried by sleeve I 48aand is rigid with cushion spring I480.

The operation. of this form of the invention is substantially that previously described except rod I34 is substituted for cable 34 and the immediate associated parts are modified as illustrated and last described.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.
