Application led January 8, 1925. Serial No. 1,159.'

My invention relates to the book-binding art and particularly to machines adapted to measure and shape the back and covers to be used in forming a volume.

The principal object of myinvention is to provide a machine for this purpose which will receive a stiff, flat strip of cardboard, or the like, (preferably furnished in standard size) designed to form the two covers and back, and to compress it transversely at the proper places to lit the volume under construction, so as to form breaks, or hinges,v in the cardboard so that the covers will be at substantially right. angles to the back and one or both Vof the vcovers will have4 a hinge so that .it may be raised from the leaves bound into the book.

My device, as illustrated, also incorpo-l rates means for compressingl the sheets and covers to be bound as well as means for drilling for binding, but primarily my invention resides in a machine for receiving the cover and back forming cardboard and shaping it to the volume under construction and providing it with hinges whereby the cover or covers may be raised from the leaves and I do not desire tobe limited in the scope'ofmy protection except as specified in the accompanying claims. i

My invention consists of the details of construct-ion as set forth herein and pointed out in my claims, the illustration disclosing a preferred form of construction.

Clin the accompanying drawings- Fig. 1 shows a perspective view of that portion of a binding machine necessary, or desirable, for illustrating my invention, which is shown attached thereto, a part-,of the crimping bar being broken away;

Fig. 2 shows a sectional view of the con.

nection between the carriage for the crimping bar I employ and the push rod which controls its positionin^ andthe slidable connection of this push rod with the binding machine;

Fig. 3 shows the cardboard before treatment in the machine;

Fig. 4 shows the cardboard after its first treatment in the machine; and

Fig. 5 shows it after its second treatment therein and compressed and ready to fit to the volume under construction.

Referring to the accompanying drawings, the reference numerals and 11 indicate the base supports of the machine with vertical standards 13 and 14 rising therefrom.

'.l'he cross' bars 15 and 16 join the base supports, as shown, `anda drill carriage 17' is slidably mounted thereon, an alinement cross bar 18 also being employed, for obvious purposes. l Y v f ylire assembly base 19 is mounted on-t'he vertical standards v13 and 14 anda pressure bar 20 is mounted for vertical movement. on screw threaded vertical shafts, 21 and 22, projecting upwardly from the assembly base.

lof the machine, one onv either side thereof. rl`hepressure bar is, preferably,recessed asv shown at l23 to permit the drills to pass therethrough and also to permit `of binding the volume before removal from the machine. 1

A, rod, or lug,v 24 projects outwardly from one end of the pressure bar its under surface engaging one arm 25 of a bell crank lever, the other arm 26 being pivotally connected to the push rod `27, anchored for slidable `movement to. theassembly base 19, said push rod being held under tension,lpreferably, by a coil spring28. The bell crank leveris pivotally mounted to a bracket 29 secured to the assembly base 19. 'v

The forward end of the push rod 27 is loosely connected to the carriage 30 to which Y 4 the crimping, or compressing leverf31r is secured. The carriage 30 is pivotally mounted to the base supports Iat 32 and 33 and'- moves radially from these mountings as it is controlled by the pushing, orvpulling, movement of the push rod 27. 'The crimping lever 31 has on its under surface the male members' 34 and 35 `of the crimping means, the female membersbeing in the base bar 36 which receives the crimping lever;

' The mounting for the crimping leveris at one end of the carriage 30 and is 'preferably/iv of the bell crank typeas shown at37, the opposite end of the crimping lever projecting beyond the side of the machine and ter-- minating in a handle 38. f

By construction the machine is so formed that the settingy of the pressure bar 2O to compress the cover and leaves moves the push rod 27 (through the operation of the bell crank'lever with the arms 25 and26) to the proper place for positioning the carriage 30 so that the operation of the crimping lever 31 will crease the cardboard, designed to form the cover and backs, in the proper place so that the back will fit the volume under construction.

A retaining bar 39 (L shaped Ain cross seclOO tion) is designed to fit above the forward v end of thev pressure bar and to be secured thereto for purposes hereinafter set forth.

For purposes of illustrating the operation of my device the numeral 40 indicates the cardboard before treatment in the machine, the

numerals

41 and 42 the creases which form the hinges for the covers and 43 and 44 the creases providing the meansyfor bending the back to a substantially right angular position with the covers before fitting and securing it to the volume being built.

In practical operation the cardboard designed to form the back and covers for a volume is of a standard size `as shown at 40. The proper length for the cover is determined by the operator and the cardboard inserted in the crimping' device and the

creases

41 and 43 formed by one operation of the lever 31. The cover is then placed, at proper position, on the assembly base and the sheets to be bound placed thereon. The pressure bar is then lowered to engage and compress the sheets on the top of this cover. (The means, other than screw threaded shafts on which the pressure barI travels, is not shown as it is not vessential to my invention and is also comprised o`f any ordinary or desired construction.) As the pressure bar moves downwardly it moves the push rod 27 rearwardly thus bringing the carriage 30 closer to the assembly base. When the pressure bar is tightly compressed against the leaves forming the volume it is obvious this will. determine the thickness of the volume beingr formed, and this positioning of the pressure bar has moved the carriage 30 into proper 'relative position that the cardboard extending over the bar 36 (the crimping lever 31 has been placed in elevated position) is properly positioned to receive the creases 42 and 44, formed by the lowering and pressing of the crimping lever, so that the distance` between the creases 43and 44 is the same as the thickness of the volume being constructed. The cardboard after the second crimping is bent up over the forward end of the volume, the back portion abutting the ends of the sheets to be bound, and the upper part of the cardboard is then bent rearwardly the portion between the creases 42 and 44 being pressed against the upper surface of the pressure bar, and the part extending from the crease 42 projecting upwardly from the right angular formation at the front of the pressure bar. The retaining bar 39 is then placed on top of the cardboard and secured to the pressure bar, this operation firmly securing the upper portion of the cardboard to the pressure bar-that part between the creases 42 and 44 being in a horizontal position and that part beyond the crease 42 projecting upwardly. The retaining bar 39 is preferably recessed at 45 to register with the recesses 23 in the pressure bar. While the cover and leaves are held in this position they are bound into the volume and then removed from the machine.

Having thus described my inventionwhat flat strip of cardboard; means positioned by the setting of the compression means to measure the cardboard to fit the volume under construction; means to shape the cardboard to form a back and hinged covers to lit said volume.

3. In combination with a book-binding machine having a pressure bar; a carriage pivotally secured to the machine; means associated-with the pressure bar for positioning 'the carriage; a crimping bar on said carriage.

4. In combination with a book-bindingv machine having a pressure bar; a carriage pivotally mounted to the machine; a crimping bar carried by said carriage; means whereby the positioning of the ressure bar moves the carriage to position or properly crimping a flat strip of cardboard to fit the volume under construction.

5. In combination with a book-binding machine, having means to compress a volume under construction, means to receive a flat strip of cardboard; means positioned by the setting of the compression means to measure the cardboard to fit the volume under construction; means' to shape the cardboard to form a back and hinged covers to fit said volume; and means to hold the shaped cardboard in position in the machine during the binding operation.
