TOR/Y6 Patented June 24, 1930 PATENT @FFlCE DAVID BAUM, OF LIVER-MORE FALLS, MAINE GLOVE-TURNIHG ItIACHIN E Application filed February 20, 1928, Serial No. 255,888.

My invention relates to improvements in glove turning machines in which plungers and tubular glove supports are employed in reversing the glove, from right side to wrong side, or vice versa.

A glove turning machine patented by me on July 27, 1920, No. 1,38,077, involving the use of these co-acting members, was provided with but one glove thumb support,

this element being swung from one side to the other of the line of finger supports to serve in turning right and left hand gloves, respectively.

In operating these machines with the single glove thumb support the uncertainty of accurately aligning the support with the plunger and holding it in alignment while the glove is being operated on is always present, and it is one of the objects of my present invention to provide a remedy for this trouble.

I employ for this purpose a bifurcated glove thumb support carrier which straddles the line of finger supports, and mount on each branch of the carrier a glove support. By swinging the carrier in either direction, so as to bring one of the supports into alignment with its respective and mating plunger, I am able to turn, alternately, both right and left hand gloves.

I am aware of the fact that others have incorporated in their glove turning machines the general idea of duplex glove thumb supports, but, so far as I have knowledge, both of these supports have been fixed in operative position on the machine, one on each side of the line of finger supports and in close relation thereto, and the support which is not in use at the time is so close to the finger supports that it greatly inconveniences the operator in placing the glove over the live operating supports, and often this is not accomplished without including the inoperative thumb support, with a consequent delay in replacing the glove over the proper supports.

My construction contemplates manual rotation of the carrier to alternately bring one thumb support into and remove the other out of operative position, which ar- Renewed November 15, 1929.

rangement provides more space bet-ween the inoperative thumb support and the line of linger supports for the operator to locate the glove than would be the case were both thumb supports immovable fixtures on the machine.

An important object is to provide automatic means, supplementing the manual actuation of the carrier, to insure a final correct alignment of the co-acting members before they actually and mutually engage, a provision made necessary on account of the fact that the operator might unintentionally neglect to place the support in its proper relation to the plunger.

And a further object of the invention is to provide, in conjunction with the aligning feature, certain arrangements of the parts to procure a safety mechanism, through the use of which it will be practically impossible to manually position either of the glove thumb supports so that accidental interference can take place between the support and plunger when the latter descends.

For the purpose of illustrating my invention I have prepared the accompanying drawings in which is disclosed one embodiment which, at the present time, I consider preferable to other possible forms in which the invention might be carried out.

In these drawings,-

Fig. 1 is a fragmentary side elevation of certain parts of a glove turning machine, the elements of my invention being shown thereon;

Fig. 2 is a plan view of the same;

Fig. 3 is a plan view of the carrier and also the several supports and plungers;

Fig. i is a plan view of the carrier and the aligning plunger assembly;

Fig. 5 is a section taken on line 55, Fig. 4, and

Fig. 6 is a section taken on line 6-6, Fig. 2, showing means for securing the thumb support to the carrier.

Similar characters of reference identify like parts in all views.

In the drawings, wherein is shown so much only of my former glove turning ma chine as will comprehensively connect the present invention therewith, 1 is the column, 2 the fixed bracket, and 3 the vertically movable bracket of my former invention.

Fixed on the bracket 2 are the finger supports 4 and adjustably secured to the bracket 3 are the finger plungers The bracket 3 may be reciprocated on the column 1 by any convenient means, as for instance that shown in my former patent hereinbefore referred to.

Secured to the bracket 3 and reciprocable therewith is a bar 6 and pivoted on the column 1, at 7, is a swinging arm 8, journalled on which at 9 is a roll 10. An ofiset portion 11 carries a helical spring 12 which normally holds the arm 8 against the column at the abutting point 13.

Referring to Fig. 2, 11 is a bifurcated or forked member which I call a carrier, and at the end of each fork thereof is removably and adjustably secured a glove thumb support 15, each support being adaptable of alignment with its adjacent plunger 16.

The carrier is pivotally secured to the bracket 2 by the pin 17 and its extreme rotary movements on the bracket in either direction are restricted by the adjustable stop screws 18.

On a central line through the carrier and journalled near the apex thereof is a roll 19 which is always in engagement with the wedge-shaped end of the ram 20, the latter being slidably mounted in the bearing 21.

\Vithin the bore 22 of the ram is a compression spring 23, one end of which seats at the bottom of the bore and the other end abuts on the head 24 of the plunger 25. A collar 26 acts to retain the plunger within the bore of the ram.

On the lower end of the pin 17 is a crank arm 27 with its forked end making connection with the connecting-rod 28. This member 28, when provided with the proper facilities for operating, such, for instance, as I adopted for a similar element in my former patented machine, is employed by the machine tender to manually actuate the carrier so as to position one or the other of the two thumb supports in at least approximate alignment with its mating plunger.

Reverting to Fig. 1, it will be observed that the arm 8 is delineated in both full and dot-and-dash lines. The former position represents the arm in its normal, inert position.

On the downward stroke of the bracket 3, the bar 6, engaging the roll 10, will cause the arm 8 to move to the position shown in dot-and-dash lines, this action swinging the lower end of the arm against the plunger 25 and forcing the ram 20 outwardly into strong engagement with the roll 19, and this engagement will occur regardless of the position in which the carrier may be at the time.

In another patent issued to me on May 12, 1925, numbered 1,537,794, having to do with glove thumb and finger supports, these elements were made with expansible tops.

In glove turning it is desirable, when using expansible top supports, to have the line of expansion of the thumb support disposed at a slight angle with the line cutting the centers of all the finger supports, and it is, of course, essential that this angle be similar in both thumb supports.

In Fig. 3 I have shown, diagrammatically, the direction of expansion of the tops of the supports 15, as on line an, and the angle between the line of expansion and the central line through the finger supports as indicated by 7).

In my earlier machine, in which a single thumb support was swung from one side to the other of the central line cc, the angle b was dissimilar in the two positions, but with my present construction it is obvious that not only similar angles for the two supports can easily be provided for, but that various different angles 7) to suit varying conditions in the grade or style of the glove may be obtained by adjusting the supports on the carrier.

In Fig. 1 I illustrate a condition which might possibly, although not probably occur in operating the glove turning machine. In this instance the operator has manually swung the carrier over from one side toward the other and left it on exactly the central line,-or in other words the ram 20 and the roll 19 are in alignment with the pivotal point 17 of the carrier, which brings the carrier to a dead center line. If the carrier should remain in this position during a downward stroke of the bracket 3, the plungers 16 would not register with the supports 15 and the thumb of the glove would not be turned. But no damage to the machlne or any of its parts could occur as all that would take place would be the compres sion of the spring 23 which would absorb the forward movement of the plunger 25. Should the roll have been carried by the operator the least amount beyond the dead center line the pressure of the ram would have thrown the earier to one side and finally brought it firmly against one of the stop screws 18 on the completion of the forward stroke of the arm 8. i

The operation of the glove turning machine with my improvements hereinbefore set forth incorporated therein, is, to all intents and purposes identical with that of my former glove turner, except in one very important particular. lVith the improved machine the operator need not concern himself n the matter of bringing the thumb support into accurate alignment with the plungerhe merely throws the carrier either to one side or the other of the dead center line, or in approximate alignment, and places the glove over the supports.

Before the glove plungers engage the glove, the safety mechanism acts to complete the oscillation of the carrier and align the parts in perfect order.

Furthermore, should the operator, using extreme care, position the carrier firmly against the stop, he is liable, in placing the glove on the supports, to accidentally move it slightly therefrom. As before, the ram 20 functions as the safety element to place the parts in proper register.

As I stated in my preamble, two glove thumb supports have heretofore been proposed for glove turning machines, but they have been applied as fixed elements and as such located permanently in their respective positions close to the line of finger supports.

In placing a glove on the machine, an operator requires considerable space in which to work in drawing the back of the glove downwardly over the finger supports. My construction allows of this as when the the operative thumb support is in close and adjacent relation to the finger supports the other thumb support is at a sufiiciently spaced distance to present no obstruction to the operators hand as he grasps the wrist of the glove and pulls it down over the finger supports.

It is obvious, therefore, that with the novel features embodied in my improvements, a vast amount of time is saved and superior advantages provided in the matter of convenience to the operator in the placement of the gloves on the turning machine.
