The workholder 13 comprises a tubular body part 29. adapted to be secured to the upper member 12 of the press, and slidably carrying a stem 17 which is urged downwardly by a spring 34. The lower end of the stem 17 passes through a block 19 and is fixed to a dovetail shaped element 20 adapted to engage in the slot of the hook tongue 3 of the fastening device 1. The clenching elements 23 are pivoted to the block 19 9 and are provided with inturned flanges 24 and upper cam edges 26 engageable with inclined surfaces 27 on, the tubular body 19. The back-plate 4, inserted between two thickness of the material 35, is located on the lower member 10 by means of spring pressed pins 36 carried by the member 10 penetrating locating holes 5 in the backplate 4 through the lower layer of material. With the hook member 1 applied to the element 20 the upper member 12 is moved downwardly by means of a foot operated lever.

Abstract: 918,710. Making gilled tubes. HAPPEL G.m.b.H., [trading as GEA LUFTKUHLERGESELLSCHAFT HAPPEL G.m.b.H. & CO. KOMM.-GES.]. Oct. 12, 1960 [Oct. 13, 1959], No. 34984/60. Classes 83 (2) and 83 (4). The subject-matter of this Specification is similar to that of Specification 922,927 except for the pusher mountings on the chain 8, and the fixed front-stop 31 and withdrawable rear locking-stop 32 of the rib-pushers 14. The chain 8 has links 29 and cylindrical links 24 on which may slide blocks 22, 23 pressed into their end positions by springs 25 and connected by a pivot pin 19 for the pusher 14. An upward extension of the block 23 houses the stops 31, 32 and a spring-loaded retaining catch (not shown) engaging grooves in the stop 32 in its withdrawn and locking positions. A device for withdrawing the stops 32 and rocking the pushers into the horizontal release position is attached by clamps 53 to chains 16 which move in the opposite direction to chain 8, the device bearing on a guide 54 on one of the roll-guides 12 of the chain 8 and having rolls 55 running on the other guide 12. A part 36 of the device carries a pivot 35 for a lever 34 which cooperates at one end with surfaces 33 in the blocks 23 and at the other with the head 40 of a retractor 41 slidable in a guide 42. When the pusher is nearing the end of its stroke in direction X, a surface 33 turns the lever 34 and advances the head 40 into the path of the stop 32. The head of the stop enters the head 40, and the stop is rapidly withdrawn by a spring 47 on the retractor when the lever is released by the control surface 33. Rubber or spring &c. pressed abutments 57 on a part 58 of the withdrawing device assist gravity in turning the pushers 14 into the horizontal, release position. The retractor 41 may be displaced by a pin 50 operated by an eccentric, and cams (nots hown) return the stops 32 when the pushers are again in the vertical. In starting a rib-threading operation, the chains 16 remain stationary until a switch on the withdrawing device is tripped by the first rib. Long tubes may be threaded from both ends successively, and the ribs may be fed from stock or from the press.
