` claims. (o1. 223-40) 1 The present invention relates to apparatus for turning or inverting gloves andthe like, as for placing seams thereof on the inside.

.An object of the invention is to provide an improved apparatus of simple and durable construction for expeditiously turning ,gloves and mittens without danger of tearing or other injury.

Another object is to provide a glove turning apparatus which is adapted to operate simultaneously on a plurality of finger sheaths.

A further object is to provide an apparatus which by simple modification can operate on either gloves or mittens.

A still further object is to provide a poweroperated glove turning machine having means for limiting the force applied to the work so as to avoid damage to the work.

The invention further consists in the several `features hereinafter described and claimed.

In the form of the invention shown in Figs. 1 to 7, a U-shaped base plate |75 is adapted to be mounted on a bench top I6 or other support.

`Spaced bracket arms l1 extend forwardly and upwardly from the base plate and carry a horizontal pivot bolt IB. An oscillatory lever comprising a pair of bars I9 is mounted at its front lso end on the pivot bolt I8 and is actuated as hereinafter described. Two vertical guide posts or rods 20 are rigidly secured to the base plate near the front thereof and are disposed between the lever bars I9, the posts being spaced transversely of the base plate. A bracket 2l of inverted U-'Shape is rigidly secured to the base plate to straddle the lever bars i9 and has a horizontal top por- 'being cut away'at their' upper front portions.l

A reciprocatory cross-head 26 is vertically movable on the guide posts 20 and has verticalbores 2l in which are clamped the lower end portions of a pair of .vertical tubes 28, the cross-head having split portions which are ,contracted about The crosshead 26 is disposed between the lever bars I9 and is conned thereon by side` plates 30. The lever bars are here shown to fit slidably in transversely channeled disk-like bearingblocks 3| which are pivotally mounted in the opposite sides of rthe cross-head. v

vA .pair of tubular .glove-supporting members 32 t snugly but detachably over the respective tubes 28 and are securedthereto, by transverse screws 33. The rounded upper end portions of the two 'spaced tubular members 32 are adapted to re-` 'ceive thereon adjacent finger sheaths of a glove G which is to be turned orinverted. Preferably, each tubular member 32 has an expansiblerv split top portion one half of which is formed by a swingable section 34 pivoted at its lower^ end on a transverse pivot pin 35. A torsion spring 36 surrounding the pivot pin 35 maintains the swing able section in its normal position. y

A pair of rods 31 are slidable in the guide tubes 25 and have forwardly projecting upper ends which are rigidly secured in sockets 38 on a l1vorl`y zontal plate 39. The plate has rigidly securedy thereto a pair oi' spaced downwardlyprojecting vertical pins or rods 4U, the lower ends of which are adapted to engage the tips of the glove nger sheaths supported on the tubular members 32 and to urge these sheaths into thetubular members. The lower ends of the pins are cupped or otherwise formed to improve the grip on the gloves. Preferably, one pin extends ltreadle 54.

Q tion.

slightly lower than the other as seen in Fig. 2,` ink cases where the glove nger sheaths are of different length. The lower ends of the slidable rods 31 are connected-t0 a cross-member 4I which is slidably mounted in slots 42 formed rounding the rods, the blocks normally abutting against Ysuperposed stop collars 46 on the rods,

and the springs being heldunder adjustableY compression by nuts or collars 47:k The .dis-

tance between the pivot bolt I8 and the crossmember 4I is approximately twice the distance i between the-pivot bolt and the cross-head 26,;

so that when Vthe lever I9 is swung downwardly the inverting pins 49 will have a downward displacement approximately twice. that ofthe tubular members 3,2, The levers I9 and the various parts connected therewith are urged to their uppermostpositions byA a coiled tension spring 48 extending between the levers and the uppermost frame cross-bar 24. A sheet metal guard 49 extends. upwardly and forwardly from the base plate I5 and thence upwardly and 'rearv wardly over the ybracket 2 I, the guard being aperturedto pass the tubular'members 32 and being secured at its rear portionv on the guide tubes 25.

The lever I9 is power-actuated on. the inverting stroke. A cord or cable 50 is connected to the rear end of the lever and extends downwardly below the bench top. where ity passes around a winding drum 5I. suitable gearing connection with a power shaft, such as that of an electric motor 52, and is driven through'a friction. clutch. 53 which is.

suitably controlled by the operator, as by a The clutch 'is preferably of the type which will slip at apredeterminedload so as to limit the downward force exerted on the lever I9 and thus. avoidexcessive stresses. on the work. Upon release of the clutch the spring 48 will return the lever I9l to its uppermost posi- Instead of intermittently actuating the dutch,

the Ymotor may be intermittently energized.. In such case the Vmotor is preferably ofV a type, such as a torque motor, which will not be injured by stalling. By limiting the motor power, in-

l jury to the work will be prevented.

The drumY has a` It is desirable to hold the lever I9 in its lowermost position. for a short time to. allow the operl ator to turn the cuil of the glove, after all the finger sockets or sheaths have been turned. This i can be done in various ways, as byfslipping the clutchv or stalling the motor, or by providing other retaining means for this purpose. 1 present instance one of the rods 31 passes through In the and is engageable by a, tilting apertured clutch or latch member loosely pivoted at 56v on the adjacent frameba'r`23 and urged upwardly by a The-latch member does, not intermember is released fromrits binding engagement, as by va treadle58.- connected t0 the latch The preferredv order of then the two remaining finger sheaths, followed Aimmediately by inverting the cuff of the glove. As all the inverting operations are similar, it will be suicient to describe the nal operation. The operator pulls the last two glove nger sheaths over the open-topped tubular members 32, the longer sheath being under the longer inverting pin. The clutch 53 is then engaged, causing the lever I9 to move downwardly and with it the tubular members 32 and the inverting pins 40, the latter moving about twice as fast as'. theV tubular members. The inverting pins force the glove finger sheaths into the tubular members, and because of the difference in theV travel of the pins and tubular members, it is not Y necessaryrto urge the glove upwardly to provide dotted lines in Fig. l. If necessary, the leverl I9 is held in its lowermost position by the latch member 55 until the cuff-inverting stop is completed. Upon releaseof the. latch, member by the treadle 58, the spring 48returns Ythe tubular members 32 and inverting members 4I! to the. position of Fig. l. The completely inverted inseam. glove is then removedY from the tubular members 32.

By slight changes the machine can be adapted, as seen in Figs. 8 and 9, to invert mittens. For this purpose the tubular members 32 of Fig. 1 are replaced by a pair of tubular members 32' having top portions which. are cut away at 60- at their adjacentY sides and which are rigidly connected by an oval band 6Iv to form a support for a mitten M. The. inverting pins 40 of Fig. l are replaced by a U-shaped member-49' which is movable downwardly into. the oval band 6I. The machine of Figs. 8 and His` otherwise the same as that of Fig. 1 and operates in, a similar manner.

In the modified form of machineshown in Figs. l0 to 12, the inverting pins 4liare Secured to a bracket 39 which is rigidly secured to the upper f is rigidly secured to the. cross-members 24 of the machine frame. The lowerend of the rod 31 is connected toa cross-member 62` whichl carries pivoted slide blocks 63 tting in the slots 42 of an oscillatory lever I9 similar to the lever I9 of Fig. l. The rod 3'1 has a stem 64 which slidably passes through the cross-member 62 and carries a compressed coiled spring 65 secured by a collar or nut 66.

The lever i9' is oscillated by a connecting rod El pivotally secured to a crank arm t8 on a horizontal shaft 69 below the bench I6,'the axis of the shaft being parallel to the pivotbolt I8. The shaft 69, which is journalled in a suitable frame' lll,` Y

has a suitable gearing connection with a power shaft, such. as that of an electric motor 52, and isY Ypreferably of the type which will slip at a predetermined load.

The operation of` the-machine of Fig. 10 is generally similar to that of Fig. 1 except that the lever I9 is swung in both directions by the revolving crank arm 58. When the cuff of the glove (or mitten) is to be inverted the lever I9' is momentarily stopped at its lowermost position, where it is held by the crank arm 63 which is then approximately in the dotted line position shown in Fig. 1i). In cases where it is desired to have the return stroke of the lever I9 faster than the working stroke, as is the case in the machine of Fig. 1, any conventional quick-return mechanism, such as the Whitworth motion, or a suitable cam motion, may be employed.
