Spinney, Greenland, NJ-L, assignor to The Morley Company, Portsmouth, N.H., a corporation of there is provided a pneumatic cylinder 32 whose one end is pivotally connected to the frame 10 by the arm 34 and whose piston 36 is connected to the central or swing Maine Filed June 13, 1961, Ser. No. 116,846 13 (Ziairns. (Cl. 1—318) ing pivot 38 of the toggle linkage 24. This invention relates to presses and more particularly to a press for automatically attaching handles to fabric materials. It is conventional to place around the periphery of a mattress handles by which the mattress may [be moved and turned. These handles are typically applied directly to the strip of fabric which forms the sides of the mat 15 For the handles to be applied, there is provided an arched guideway 40 (FIG. 3) whose upper end extends over the press so that handles may be easily loaded into the apparatus from the front of the press and thence con ducted by gravity to the reciprocating head 20. The handles 42 (FIGS. 7 and 8) are provided with pre-at tached pronged fasteners 44 which, as may ‘be seen in FIG. 4, include a plurality of pointed prongs 46. These prongs ?t in corresponding slots in the ends of the han , tress. It is thus a primary object of the present inven tion to provide apparatus for applying handles to such dle (FIGS. 8 and 10) and, before attachment to the fab ric strip, are held there by friction. After proceeding material quickly and cheaply and with as little human down the guideway 49 the handles 42 arrive at a position supervision as possible. _ Further objects are to provide such apparatus which 20 er 5%} (FIGS. 7, 8 and 9) which is attached to the frame 16 and which includes the pair of pivoted arms 52 which is largely automatic, Which is highly reliable, which forms are biased by the spring 54 to hold the leading handle a very secure attachment between handle and fabric, in the path of the reciprocating head 20. The arms 52 which is not subject to rapid wear, which is easily ad hold the handle by tapered edges 56 so that, as the head justed and repaired, which is compact, and which is rela tively inexpensive. 25 20 comes down and the driving dies 22 engage the cor In achieving these objects the invention contemplates respondingly spaced fasteners 44, the handle is taken from a press which will apply handles having pre-attached pronged fasteners of the type in which the prongs are the positioner 50 and carried down into engagement with the fabric 1'6. To prevent the possible bowing of the handles the head 20 is provided with a spring loaded pin adapted to engage a locking ring. The press has a re 59 which bears lightly against the central portion of each ciprocating head which forces the prongs of the fastener through the fabric and into a closing die which turns handle 42 as it is fastened to the fabric strip. On the opposite side of the fabric 16 and positioned by the prongs. In a preferred embodiment a plurality of closing dies are provided and are spaced around a disk means to be explained hereinafter, there is a closing die which is rotated so as to bring successive dies into posi 60 (FIG. 10). Resting in this die, is a locking ring 62. tion below the head. Preferably there is provided means 35 As the driving dies 22 continue downwardly the prongs for automatically loading locking rings into the closing 46 of the fastener 44 are driven through the fabric and are turned outwardly by engagement with the closing die dies as the disk rotates. Preferably also there is provided a means for feeding handles successively into the recip 60 so as to engage and lock with the locking ring 62 in rocating path of the head so that the head with each the manner shown in FIGS. 10 and 11. Preferably, there stroke carries a handle into engagement with the fabric. 40 is provided concentric with the driving die 22 and fas For purposes of illustration a preferred embodiment tened to the head 20 by the same screw 23, a permanent of the invention is shown in the accompanying drawings in which FIG.

So that the locking rings 62 may be automatically pro vided as needed, the press includes a plurality of closing dies 60 which are spaced around the peripheries of a pair of disks 65 which may be rotated so as to bring successive locking dies 60 into position under the respec 50 tive driving dies 22. The disks 65 are set into the bed 14 of the press so as to provide a ?rm support for the fastener closing action. At a portion of each ‘disk re moved from the operating position, there is provided a locking ring tube 67 (FIGS. 1 and 2) which is adapted 55 to drop a single locking ring into each empty closing die 60 as it passes 'by the tube. For rotating the disk 65 there is provided a second FIG. 12 is a schematic representation of the pneumat pneumatic cylinder 70 (FIGS. 5 and 6) which is adapt~ ic control system for the press. ed to move the levers 72, 74 and 76 so as to rotate the Referring now to FIGS. 1, 2 and 3, the press is built 60 ratchet drive 78 which in turn unidirectionally rotates the around a frame 10 which includes a top cantilevered por disks 65.
