SHEET-HANDLING MACHINE.

Application filed April 28, 1915.

To all whom it may concern:

Be it known that I, 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.

This invention includes means whereby each successive signature is led from the press through a different stitcher mechanism than the preceding signature.

The invention also includes means for positively removing the stitched signatures from their stitcher mechanisms and folding off said signatures.

This invention also includes means whereby the stitched signatures are folded and delivered'to different delivery mechanisms.

This invention more specifically includes means whereby the signatures are alternately fed to two stitcher mechanisms and are positively removed therefrom by grippers carried by the rotary folding-off cylinders, which, in turn, fold off the stitched signatures to a common. coacting folding cylinder from which the folded signatures are delivered in succession to two delivery mechanisms.

This invention also more specifically includes two delivery devices including delivery cylinders, a common female folding cylinder having two sets of folding jaws arranged to transfer the stitched and folded signatures to the delivery cylinders, two

male folding cylinders having tucking blades arranged to co-act with their corresponding sets of folding jaws, two stitcher mechanisms, grippers on said male folding cylinders for positively removing the signatures from the stitcher mechanisms, feedingin devices for the stitcher mechanisms, and a common feeding cylinder having two sets of grippers arranged to coact with their respective feeding in devices to transfer the signatures thereto.

The object of this invention is to provide means for rapidly stitching, folding and delivering signatures and, at the same time, permit the stoppage of the signatures and ample time to allow them to be accurately stitched.

Specification of Letters Patent.

Patented J an. 8, 1918.

Serial No. 24,511.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 is a vertical central section taken from front to rear through so much of a sheet handling machine as includes my invention,

Fig. 2 is a detail vertical section taken from front to rear inside the near side frame,

Fig. 3 is a detail vertical section taken from front to rear inside the far side frame, and

F ig. 4: is a detail section showing the driving connection between theparts and also certain of the cam mechanisms.

A feeding cylinder 1 mounted on the shaft 2 carries two sets of grippers 3, f, arranged to take successive signatures as they are fed from the cutters 5, 6, through the guides 7, 8, and feed the signatures alternately to the cylinders 9, 10, of the feedingin devices for the stitcher mechanisms.

The shaft of the cylinder 9 is denoted by 11, and of the cylinder 10 by 12. he set of grippers 13 on the cylinder 9 is arranged to take a signature from the set of grippers 23 of the cylinder 1 every revolution of the cylinder 1 and every two revolutions of the cylinder 9.

The set of grippers 1 1 on the cylinder 10 is arranged to take a signature from the set of grippers at of the cylinder 1 every revolution of the cylinder 1 and every second revolution of the cylinder 10.

The upper stitcher table is denoted by 15 and the lower stitcher table by 16.

A movable stop 17 is provided for the table 15 and a movable stop 18 is provided for the-stitcher table 16.

The upper stitcher mechanism is denoted by 19 and the lower stitcher mechanism by 20, which stitcher mechanisms are driven respectively through suitable gearing from the shafts 21, 22.

Endless tape carriers 23, 24, are arranged to feed the signatures from the cylinder 9 onto the stitcher table 15 against the movable stop 17. Similarly, endless tape carriers 25, 26, are arranged to feed the signatures from the cylinder 10 onto the stitcher table 16. against the movable stop 18.

The upper male folding cylinder is denoted by 27, its shaft by 28, its set of grippers by 29, and its tucking blade by 30.

The lower male folding cylinder is denoted by 31, its shaft by 32, its set of grippers by 33 and its tucking blade by 34.

The common female folding cylinder is denoted by 35, its shaft by 36, and its two sets of folding jaws by 37, 38, respectively.

The upper delivery cylinder is denoted by 39, its shaft by and its set of grippers by 41. The lower delivery cylinder is denoted by 42, its shaft by 43, and its set of grippers by 44. The upper endless delivery carrier is denoted by and the lower endless delivery carrier by 46.

A short circular cam 47 is arranged to operate the grippers 3 of the cylinder 1 to close them on the signature at their receiving point and to open them at the proper time to release the signature to the grippers 13 of the cylinder 9. A long circular cam 48 is arranged to operate the grippers 4 on the cylinder 1 to close them on the next succeeding signature at their receiving point and to open them to release the signature to the grippers 14 of the cylinder 10. The cam 49 controls the operation of the grip pers 13 and the cam 50 controls'the operation of the grippers 14.

The movement of the sheet stop 17 is con trolled by the rotary cam 51 carried by the cylinder 27 and the movement of the sheet stop 18 is controlled by the cam 52 carried by the cylinder 31.

The grippers 29 on the cylinder 27 are shown as tumbler operated and they are controlled at their receiving point by the pin 53 and at their releasing point by the pin 54. Similarly, the grippers 33 on the cylinder 31 are shown as tumbler operated and they are controlled at their receiving point by the pin 55 and at their releasing point by the pin 56.

The coacting folding mechanisms are of the floating tucking blade and floating folding jaw type of well known and approved form and their operating cam mechanisms will not be specifically described herein as they form no part of the present invention.

A stationary cam 57 is arranged in position to open the folding jaws 37 to transfer its stitched and folded signature to the delivery cylinder 39 and the stationary cam 58 is arranged to open the folding jaws 38 to transfer its stitched and folded signature to the delivery cylinder 42. A fixed cam 59 is arranged in position to operate the grippers41 on the upper delivery cylinder 39 to receive its stitched and folded signa ture from the cylinder 35 and deliver the said signature to the delivery device 45. A fixed cam 60 is arranged in position to operate the grippers 44 of the lower 'delivery cylinder 42 for receiving its stitched and folded signature from the folding cylinder 35 and deliver the same to the delivery stitcher mechanisms, are driven from theshaft 2 of the cylinder 1 through the train of gears 61, 62, 63, 64. The shafts 11, 12, of the cylinders 9, 10, are driven from the gear. on the shaft 2 through the gears 66, 67. The cylinders 27, 31, 35, 39 and 42, are driven from the gear 67 through the train of gears 68, 69, 70, 71, 72, 73.

In the form herein shown, the cylinders 1, 9, 10, 27, 31, 35, 39 and 42 are all drive at the same surface speed. '1

By sending one signature to one stitcher mechanism and the next signature to another stitcher mechanism, I am enabled to stitch one signature while the other one is being fed in position to be stitched.

By. providing a plurality of deliveries, I am enabled to stitch and fold separate products and deliver them in diiferent piles.

By the term cylinder, as used in the description, I contemplate any suitable means for passing the signatures through the prescribed paths, and by the term grippers, I contemplate any engaging devices suitable for the purpose of leading the sig- 7 natures through said prescribed paths.

It it evident that slight changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit my self strictly to the structure herein set forth, 7
