This invention relates to improvements in machines for reversing or turning gloves from wrong side to right side,

1Machines of this characterV have usually been constructed with co-acting plungers and glove finger tubular supports, the plungers forcing the fingers of the glove, for substantially their full lengths, into the supports and in so doing reversing them.

This method of turning gloves, especially of the heavy, stiif kind, has the disadvantage ofplacing a severe strain on theseams and often results in the necessity of restitching them. Y 1

It is an object of my .present invention to eliminate, so far as possible,this tax on the strength of the seams of the glove while being operated on by pulling the ngers over the plungers rather than forcing them into the supports. Y 1 1 v A further object is to provide means to hold each respective finger tip interposed between a plunger and its mating support, whichlatter I preferably make solid instead of tubular, continuing this contact during the entire time it is in process of turning,-r`e laxing this contact with the support imme diately each tip has been completely reversed.

,Other objects will be apparent from the description found hereinafterin the specification when takenl in connection with the accompanying .drawings in which 1 is disclosed one embodiment, which, at the present time, I consider preferable to other possible forms in which the invention might beV carriedout. 1 Y

Similar characters of reference are employed to indicate similar parts in all the .diiferent views of the drawings. 1 `Referring to the drawings, 1 represent the frame of the machine and 2 a xed bracket on which are the glove finger supports 3 and the glove thumb support L1.

Slidable onthe front of the frame is the movable bracket 5, at a point 6 on which is pivotally attached the connecting-rod 7. A rocker 8 is fixed to the shaft 9 and makes connection with the connecting-rod 7 at 10. A crank-shaft ll-is journalled in the frame 1 and fromithe crank-pin 12 operates the link 13 which is pivotally connected to the rocker at 14. These several last mentioned elements supply the means to actuate the mov- In a glove-turning machine patented by me on July 20, 1920, numbered 1,348,077, I employed plungers and tubular glove finger supports and glove gripping members, the

v function ofthe latter being to grasp the wrist portion of the the supports.

VThese gripping members 15 I retain on my present machine. and are therefore not involved in any of the novel characteristics of my present invention. 1 1

Slidably supported on suitable guides, as the standards 16, is a plunger carrier 17 provided with the cam shaft 18 on `which are fixed five cams, 19a, 19h, 19e, 19d and 196,- being, respectively, the cams which operate on the tops of the plungers 20a, 20", 20c, 2Qd and 20e. These plungers are reciprocable 1n suitable bearings in the plunger carrier and are also slidable in and guided by similar bearings in the movable bracket 5.

Two arms, 21 and 22 having slots 23 1n their outer ends are fixed on the shaft 24 which latter is journalled in the frame 1; On the arm 21 is a segmental gear 25 adapted to engage the rack-rod 26Which is reciprocable inthe bearings 27 and 28.

Secured to the crank-shaft 11 is a cam disc glove and pull it off 29 having in its side the path cam 30. AV roll a 31, on the pin 32 operates in this path and the pin'being secured in the rack-rod 2G functions to produce a reciprocatory movement to the latter. This movement isintermittent, as will be hereinafter more fully described.

Suitable counter weights 33 and 34 are suppliedr for the arms 21 and 22 and the rocker 8, respectively. A pulley and clutch ottany approved type 35 and pedal 36 are provided to start the machine into action.V

Near the top of the frame 1 is ashort gear rack 37 and on the cam shaft 13 is a gear 38,-the latter, when the plunger carrier has descended sufficiently, being adapted to engage the rack 37 and rotate the camshaft 18 and the several cams thereon. p

On each side o'l' the plunger carrier 1 7 are studs 39 operable in the before mentioned slots 23 in the arms 21 and 22, and on the top end of each of the plungers 20M-2()e are rolls 40. Springs 41 thrust against the collars 42 on the plungers and on the base of the plunger carrier and serve to keep the rolls 40 in close contact with the cams. K

For greaterV convenience in illustrating their relative positions, I have shown the glove thumb plunger and support, inV Figs. 9 and 10, in the same plane as the finger plung-A ers and supports.

After placing a glove, G, on the supports and tripping the clutch, the movable brack- .et 5 and the plunger carrier 17 move down wardly in synchronized order through substantially one half of a revolution of the crank-shaft 11. solidly on the finger tips lying over the tops of the supports,-as seen in Fig. 9. Italso moves the relative position kof the rollr 31 in the path 30 from extreme inward position to extreme outward position g/. During a portion oi' the return, or upward movement of the bracket 5 the grippers lift and reverse the glove to the extent of completely turning the thumb e, (see Fig. 10), this action taking place without vertical movement oi' the plunger carrier 17,-the roll 31 operating in the concentric portion or" the cam path 30, or relatively, from position y to position a (see Fig. 1.)

Further upward movement of thegrippeis would push the thumb plunger 2Oe through the thumb e oiI the glove were no provision made to allow the plunger to recede at the same speed as the grippers travel upwardly. In Fig. 11 is shown the cams which effect this receding movement of the plungersfvthe rotation of the cams being` in response to the quick upward lift given the plunger carrier by the passage of theroll 31 from position at e to the starting point at ai and causing in this movement the rotation of the gear 38 meshed in the rack 37.

But, while the thumb 'e has now been re- This places the plungers versed, the lingers, a, Z), 0 and l of the glove have been only partially turned, and it is desirable to hold the plungers so that contact of the linger tips with their respective supports may be continued until such time as they, individually and' successively, have also been completely extended. It is therefore obvious that, as the plunger carrier is rising, cams with downwardly tending forms, as at 43, 44, 45 and 46 must be provided which will supply a relatively downward or reverse movement of the plungers to compensate for the upward Atrend of the plunger carrier; in other words, the plungers must be held for a certain period of time motionless or inert, with respect to the glove ngers and their supports, although during this time the plunger carrier is moving upwardly.

Then the linger tip next in elevation to the thumb,-the little inger,-is fully ex'- tended, the cam serving the little Iinger plunger, 19d, acts to allow this plunger 2()d to recede at the same upward speed at which the movable bracket 5 moves.

Each of the other mating cams and plungers co-act in a similar manner at the proper time, and'immediately after all the respective fingers have been turned the gear` 38 becomes disengaged from the rack 37 preventing turther movement of the pluiigers relative to the plunger carrier and both rise to the extreme upward position leaving the plungers in re-y versed position with respect to their lower ends from that' in which they were disposed at the start of the turning operation.

Oncertain grades of gloves it is Vpossible `to use a somewhat different method of hold'- ing each tip onto its respectivesupport unt-il it has beencompletely reversed. In Figs. 4 to 7 inclusive, I show ay finger support, 47, similar in many respects to the one patented by me on May 12, 1925, No'. 1,537,794 but dif- )tering in this particular,-the slight inward overhang 48jon the tops of the expansible blades located in line of expansion of the latter. This serves to hold the linger tip, frictionally, within the hollow support (see Fig. 7) after the plunger has receded and until the grippers act to pull itout.

In this arrangement the cams 19a to 19e, together with the rack 37'and gear 38 are discardedk and the plungers iixed in the plunger carrier 17 as seen in Fig. 12; and operation, theplungers remain on the supports, the glove vbeing interposed, until the thumb has been completely turned, and immediately thereafter all the plungers move simultaneously upward,-the tips of the partially turnedV fingers remaining within the tubular supports until each, in the order of their respective lengths, is fully extended by the vertical pull of the glove grippers. l

Although I have shown in my drawings no provision to accomplish the object, I may elect to provide similar means as was ein# said glove-gripping members.

Pers Q It is obvious that the characteristic feature of my present invention resides-in the manner of handling the fingers of the `glove in-the turning operation. In the preferred arrange-V ment, the tops oit the` finger supports are slightly concaved so that abetter holding surface is presented to the plungers @while in the alternate method, the finger tips are lmade to enter the tubular supports for but a very short distance,-the main concept,'in'both instances being toget away from the necessity of torcing substantially the whole length Y oi the fingers into the supports..
