The present invention provides a highly simplifled glove turningapparfatua adapted to effect considerable economy of time and labor in the op eration. otinverting glove as a final-operation in the production thereof.

otthe head: and associated moving parts;

Reciprocation of head I8 is accomplished by: means cl 2. double-acting air cylinder 23 which is appropriately mounted in fixed position on the apparatus. In the illustrated embodiment the cylinder is secured to the upright l2, as by welding or by other means not necessary to illustrate or describe. A piston or plunger 24 is reciprocable vertically in cylinder 23, being secured to a connecting rod 25 which extends through packings in either opposite ends of the cylinder. Said rod at its upper end is rigidly connected to a lateral arm 29 which extends through a vertical slot 21 in upright web 14 and is secured at its forward extremity to the head l8.

At its lower end the piston rod 25 is rigidly secured to a crosshead 28, which crosshead is further connected to head l9 at an intermediate point by means of a Vertical pivoted link 29. This link extends upwardly through an aperture in table I and is pivoted at its top extremity to head 18.

The cylinder 25 has air fittings 30, 3! at opposite ends thereof which are connected by pressure tubes 32, 33 respectively to a conventional type of pedal operated, reversing valve 34, in turn connected by a supply line 35 with a source of air or other operating fiuid under pressure. The valve control pedal 34, by which the operator controls the apparatus, extends forwardly of the table [9 to a convenient point.

The above and following instrumentalities are all conventionally illustrated, no attempt having been made to show exact details or proportions, and it is apparent that many refinements in design or arrangement are possible. It will be appreciated that as operating pressure is applied to one end or the other of cylinder 23 under control of valve 34, the head 58, connecting rod 25 and crosshead 28 will be caused to reciprocate vertically, being guided in a vertical sliding movement on the post it. To this end, link 29 serves to equalize the application of lifting effort on the head and crosshead and to prevent wracking action thereon. As stated, spring 22 serves to compensate for the weight of the reciprocating parts, so that the work done on opposite sides of the piston 24 will be equal.

At its forward end, the table In carries a plurality of vertically extending, tubular stripping sleeves 36 which are of hollow, cylindrical character. These sleeves are secured in lateral alignment on the table, over a corresponding number of apertures 37 in the latter. Said apertures receive the parallel upright rods 38 attached to a block 33 which has a vertical slot 38 therein receiving the forward end of crosshead 28. Rods 38 extend for a considerable vertical distance through the sleeves and have attached to the upper ends thereof the stripping plungers 39. Crosshead 28 carries a depending spring guide 39' which extends through and beneath block 38', a coil spring 39 encircling said guide and abutting the block and an adjustable washer 39" at its opposite ends. Therefore, as crosshead 28 reciprocates downwardly, block 38 will be reciprocated therewith, after a lost motion interval and when the crosshead abuts the top and bottom of slot 38". The plungers 39 are positioned with reference to one another and the sleeves in the manner illustrated in Fig. 2.

In vertical alignment with each of the plungers 39 the upper reciprocable head 18 carries a corresponding number of vertical glove positioning fingers 4 .5. These are mounted for vertical adjustment relative to the head l8 by nuts 4| which threadedly engage the upper extremities of the fingers on either side of the head. It will be noted that the fingers are in substantially vertically spaced relation above the plungers 39, enabling the fingers of a glove to be turned, designated 42, to be conveniently positioned upside down over said fingers 49, and as the head I8 reciprocates downwardly with the plungers, the glove fingers will enter the sleeve 36 a substantial distance, as illustrated in Fig. 4.

In operation, with the parts in the position illustrated in Fig. 1, an operator first positions the four fingers of a glove to be turned on the glove positioning fingers 40, in the manner illustrated in Fig. 3. He then depresses the pedal of the reversing valve 34, which causes operating fluid to be admitted above piston 24, shifting head l8 and crosshead 28 downwardly. This causes the fingers 49 to insert the glove fingers to a substantially telescoped position internally of the stripping sleeves 36. Spring 39" maintains block 38' and plungers 39 in elevated condition until fingers 49 engage the descending glove whereupon the plungers also descend. Alternatively, the length of slot 33" may be designed so that the block is depressed by direct action of crosshead 28. The stroke of fingers 49 is sufficient to cause full insertion of the glOVe fingers into sleeves 36 without damage to the interconnecting webs or palm, and is readily adjustable by manipulating the nuts 4-]. The operator then strips the upper part of the glove down over the sleeves 36 in the manner illustrated in Fig. 4.

With the parts in the position noted, the operator then releases pedal 36 which automatically causes reversal of the application of pressure fluid to the lower end of cylinder 23, whereupon the head and crosshead rise,

Block 38 follows in contact with the glove fingers under the force of spring 39", causing initial reversal of, said fingers, until said spring reaches relaxed condition. Thereafter the crosshead continues to rise under air pressure, separating fingers 43 from plungers 39, as illustrated in Fig. 5. When the crosshead strikes the top of slot 38 immediately thereafter, the ascent of the plungers is completed under air pressure, positively completing the reversal of the glove, as shown in Fig. 6. Reference to Fig. 5 indicates that there is sufficient radial clearance between the plunger and sleeve 36 to avoid destructive jamming or rubbing and enable ready reversal of the fingers. When the parts come to rest, the glove is lifted off the plungers in a fully turned condition.

While I have illustrated an extremely simple embodiment of the invention, and in fact one of the primary advantages of the apparatus is its simplicity, it is appreciated that many refinements can be introduced into the apparatus, for example, a full five fingers of each glove can be inverted in one operation, with certain simple changes. Likewise, the plungers 39 are intended to have electric or like heatin elements embodied therein, so as to effect a hot pressing and conformation of the fingers as they are turned on the plungers. Further provisions, such as automatic control and timing instrumentalities, will suggest themselves to those skilled in the art.
