SHEET-HAN DLIN G MACHINE.

. To all whom it may concern:

Be it known that 1, HOWARD M; BARBER, a

citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement 'in Sheet- Handling Machines, of which the following is a specification.

()no object of this invention is to provide means whereby a signature is stitched While at rest and is then removed from the stitcheg' table at a speed sufficient to cause it to clez': r the next succeeding signature as it is fed onto the stitcher table, such arrangement permittingthe stoppin of the signature on the stitcher table a sufficient time to allow it to be accurately stitched.

Another object is to provide means for adjusting the opening and closing movements of-thev grippers on the cylinder which takes the stitched signature from the stitcher table and folds the signature, so-that the grasping and releasing moments of the grippers -may be timed with respect to the folding operation while the machine is in operation, for insuring the accurate folding of the stitched signature.

A practical embodiment of my invention is represented in the accompanying drawings, in which that part ofa sheet. handling machine-is illustrated which includes my in-.

vention,

the line AA of Fig. 7 looking in the direction of the arrows, and

Fig. 9 is a detail section similar to Fig. 7 with certain of the parts removed and other parts broken away. j

The stitcher table is denoted by 1, the stitcher by 2, and its driving shaft by 3, which stitcher may be of any well known or approved construction adapted to stitch a signature While the movement of the signa-' ture is arrested.

The signature transfer cylinder 4: is mounted on a shaft 5 and its set of grippers 6, is arranged to transfer the signature to the "-se't of. grippers 7 of the transfer cylinder 8 cylinder 8 and the pulleys 13, 14. The end- I less tapes 11 pass around the pulleys 15, 16, 17, 18. The sheet stop 12 is mounted on a rock shaft 19 to which is fixed a rock lever 20 having a studor roller 21 under the control of a rotarycam 22 rotating with the male folding cylinder 23. This cylinder-23 has a set of. tumbler actuated grippers 24 and the floating tucking blade 25 of a folding mechanism. r i

he female folding cylinder 26 carries the floating folding jaws 27 of the folding mechanism. y e v The shaft of the male folding cylinder 23 is denoted by 28 and the shaft of the female folding cylinder 26 is denoted by 29. I A suitable delivery mechanism is employed for deliverin the stitched signatures from the female folding cylinder 26, which delivery mechanism,

comprises the two sets of endless tapes 30,

in the present instance,

31, the endless tapes 30 passing around the cylinder 26 and the pulleys 32, 33, and the endless tapes 31 passing around the ulleys 3e, 35, 36. The signatures are de ivered from the delivery tape carriers onto a dropper delivery mechanism 37 from whence the signatures are dropped onto the tapes 38 of an endless delivery carrier, which tapes pass aroundv

suitable pulleys

39, 40.

The transfer cylinders 4 and 8, the tape carriers 10 and 11, and the stitcher 2, are driven through the train of

gears

41, 42, 48, 44, 45, 46, 47, 48, 49. 7

The male folding cylinder 23 is driven from the vertical shaft 50 through the train of

gears

51, 52, 53, 54, 55, 56, to which lastnamed gear the rotary cam 22 is fixed.

The female folding cylinder 26, the

endless tape carriers

30, 31,: and the dropper delivery mechanism 37 are driven through the train of gears 57, 58, 59, 60, 61, -62, 63.

The endless delivery carrier 38 is driven from the shaft 29 of the female folding cylinder 26 through the bevel gears 64, 65, shaft 66, worm gears 67, 68, and spur gears 69, 70.

The relative speeds of the driving mechanisms hereimihove referred to, are such that the stitched signatures are withdrawn from the stitcher table at a speed equal to or :itcr than the speed of the press thus giving ample time for the stitching of the signature while it rests on the stitchcr table and the removal of the stitched signature without interfering with the oncoming next succe ding unstitched signature.

'lr ,he relationship of the parts as shown in the accompanying drawings, the shafts 5 and 9 of the transfer cylinders, are driven at the same speed as the

shafts

28 and 29 of the folding cylinders. The stitched signature in this instance will be removed from the stitcher table at a greater speed than its feeding in movement because of the lar er circumference of the male folding cylin'er The movable sheet stop 12 is held in its stoppin position about one-half the revolution of the male folding cylinder 23 and in its released position the other half of the revolution of the said folding cylinder.

The cam mechanism for controlling the floating of the tucking blade and folding jaws in parallelism during the folding of the signature off from the male foldin cyl inder 23 onto the female folding cylin or 26 will not be specifically described herein as it is of well known and approvedconstruction and forms no part of the present invention. v

I employ adjustable means for closing the grippers 24 onthe male folding cyllnder 23 at their signature receiving point and for opening the leasing point so that the position of the signature with respect to the folding device to insure an accurate folding of the signature may be regulated without disturbing the operation of the folding device or the operation'of the machine. I

The adjustable means which I have here- ,in illustrated is constructed, arranged and operated as follows: The shaft. 71 of the grippers 24 is provided with a tumblercam grippers at their signature re 72 which is engaged bythe pin 73 at the signature receiving position of the grippers and by the pin 74 at the signature releasing position of the said grippers. The pin 73 is carried by a bracket 7 5 fitted to slide on a stationary bracket support 76. The pin 74 is carried by a bracket 77 fitted to slide on a stationary bracket support 78.

A gib 79 serves to hold the bracket 75 in position on its support 7 6 and a gib 80 serves toliold the bracket 77 in position on its support 78? These brackets 75, 77, with their

pins

73, 74, are movable concentric with the shaft 28 of the male folding cylinder 23 so as to keep the

pins

73, 74, at all times in-their proper radial position with respect to. the ripper tumbler cam 72. The bracket 75 ant its pin 73 are adjusted circumfercntially by an eccentric cam 81 on a shaft 82 mounted in the bracket sup ort 7 6 and gib 79, which shaft is turned ro'm a hand shaft 83 through a worm and gear connection 84, 85. This hand shaft 88 is mounted in a bracket 86 secured by bolts 87 to the support 76 I Similarly, the bracket 77 and its pin 74 is adjusted circumferentially by an eccentric cam 88 on a shaft 89 mounted in the'sup port 78 and gib 80, which shaft is turned from a hand shaft 90 through a. worm and gear connection 91, 92. This hand shaft is mounted ina suitable bracket 93, secured to the support 78 by bolts 94, The handles of the shafts 83 and 90 are denoted, respectively, by 95 and 96. The gib 79 is secured to the bracket support 75 by the bolts 97 and the gib 80 is secured to the support 78 by the bolts 98.

The supports 76 and 78 are independently adjustable in a rotary direction on the side frame, in the present instance, by providing the frame and the supports with holes 99, 100, engaged by adjusting bolts 101.

By the term cylinder. as used in the description, I contemplate any suitable means for passing the sheets and signatures through the prescribed paths and by the term grippers I wish to include any engaging devices suitable for the purpose of leading the sheets or signatures through said prescribed paths. 1 i

It will be seen fromthe above description that the signature may be stopped a sufficient length of time to be properly stitched and is theh removed by a device which will start it off the 'stitcher table at a speed which will insure its free removal from the stitoher, table without interfering with'the incoming unstitched signature.

It will al be seen that by the provision of stationary means for ad ustin the operation of the grippers on the fo ding off cylinder, the accurate folding of the stitched signature may be accomplished without stop- 55 Y mechanism for arresting the-movement of ping the machine or interfering with its operation.
