Abstract: 9571. Jacobs, A. I., and Smyth Manufacturing Co. May 8. Bookbinding.- Relates to machinery for pasting unbound books and then applying cases or covers. The book is opened at the middle, and placed b a c k upwards on a vertically - reciprocating supporting - plate 34, Figs. 1 and 3, when this is at the upper limit of travel. The plate is secured to an arm 33 attached to the front of a slide 31, which is adjustably linked to a lever 22 carrying a roller engaging a cam-groove in one side of a disc 19. This disc is mounted on a shaft 18 driven by gearing 17, 14 from a pulley 12. A lever 26, carrying a roller engaging a cam-groove in the other side of the disc 19, is linked to a rocker arm 84 on a shaft 85, which has an arm 86 provided with a segmental rack meshing with a similar rack on an arm 87 of a shaft 88. Other rocker arms 89 on the shafts 85, 88 are linked to studs 91 extending through the bottoms of paste receptacles 56 and retained by springs 92. The receptacles 56 rest on rollers, and are provided with feed-rollers 60, 61 geared together and fitted with scrapers 64, 65 respectively. The rollers are rotated as follows :-Yokes 67, Figs. 3 and 7, movable in gibs 66, support studs 68 carrying gear 69 for racks 70 arranged to move transversely with the yokes and also freely vertically. The lower ends of the racks are mortised to fit over a rib 72 at the back part of the slide 31, Figs. 1 and 3. A pawl ring 74, Fig. 7, is loosely connected to the gear 69 by a pin 73, and provided with a pawl 75, which engages a driving-ring 76 having a hollow hub 77 in which is a disc 78 attached to a rod 79 provided with a handle 80. The disc engages two loose pins 82 in the hub, and, when the handle 80 is pushed inwards, the pins engage perforations in gear 63 on the shaft of the paste roller 61, Fig. 1. A presser-arm 37, Figs. 1 and 3, is pivoted in a mortice near the upper end of a bar 35 attached to the back part of the slide 31. The front of the presser-arm projects above an opening 38 between sliding table plates 39. Movable blocks 40 on the arm are provided with frames 41 connected by yielding webs 42. The rear end of the arm is loosely connected to a rod 43 passing freely through a block 46 moving with the bar 35. A spring 44 is placed between the block 46 and a collar 45 on the rod 43. An adjustable collar 47 is also provided on the rod 43. When the bar 35 is near the lower limit of travel, the front end of the presser-arm engages a bar 48, and is caused to oscillate against the pressure of the spring 44 and allow for placing a case or cover on the plates 39. As the bar 35 approaches its upper limit of travel, the collar 47 on the rod 43 engages gibs 36, and the front end of the presser-arm is swung upwards from the edge of the book support. The tables 39 are provided with movable registering-blocks 55, and also with perforated lugs, not shown, one with a right-hand thread and the other with a left-hand thread for the reception of a correspondinglythreaded shaft 52, which extends loosely through a retaining-block 53, and is squared for the application of a wrench or handle, for adjustment of the opening 38.
