CREASIhTG AND CUTTING ATTACHMENT FOR RULING-MACHINES.

Specification of Letters Patent.

Patented Aug. 1, 1916.

i Application filed February 26, 1916. Serial No. 80,631.

To all whom it may concern Be it known that we, JOSEPH HAYEs and GEORGE HORN, both citizens of the United by set screws 19 or other suitable devices,

States, and residents of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have in vented a new and ImprovedCreasin'g. and Cutting Attachment for Ruling-Machines, of which the following is a' full, clear, and exact description.

Among the principal objects 'which the present invention has in view are: to provide means for simultaneously imprinting lines on paper and for forming creases or scores therein to form flexing surfaces; to provide means for creasing and cutting paper while passing through a ruling machine without interrupting the feed or injuring the conveyer belt for supporting the paper; to pro ide means for driving the cutters and creasers in synchronism with the operation of said conveyer and the feed of the paper thereon;'and toprovide a mechanism of the character mentioned adapted for installation on and removal from machines of conventional form and operation.

Drawings-Figure 1 is a top plan view of a machine constructed and arranged in accordance with the present invention, showing in conjunction therewith a sheet of paper being ruled, creased and trimmed, said sheet and parts associated therewith being shown as parted and contracted; Fig. 2 is a cross section of the same, the section being taken as on the line 2-2 in Fig. 1; Fig. 3 is a vertical section taken as on the line 3-3 in Fig. 2; Fig; 1 is a cross section taken as on the line 4 1 in Fig. 2; Fig. 5 is an assemblage of the creasing rollers, conveyer belt, guide rollers therefor, and paper carried thereby.

Descriptom-The conventional ruling machine has a conveyer belt 10 suitably sup ported at the front and rear ends of the machine. Intermediate the said ends and extending between the side rails 11 of the machine, is a fountain 12, having marking pens 13. A suspension device, such as the disk 14, is employed for lowering and lifting the pens 13 and fountain 12 therefor.

In accordance with the present invention, the conveyer belt 10 is utilized for delivering the conveyed sheet to rotary creasers 15, and also to rotary knives. 16

when employed. The creasers andknivesare rigidly mounted on shafts 17 and 18, the

'held gripper feed rolls 20.

former being disposed above the belt 10 and the latter below the belt 10. Said creasers and knives are held in service on said shafts which may be released to. permit shifting or removing the said creasers and knives. On the shafts 17 and 18 are also rigidly The gripper feed rolls 20 are provided with set screws 19, to permit shifting said rolls in the manner as above outlined with regard to the knives 16 and creasers 15.

The creasers, knives and feed rolls above mentioned are employed when the ruling machine is used for turning out leaves for use in loose-leaf binders, wherein a creased section 21 is formed to facilitate the flat disposit-ion'of the sheets in service. Heretofore when the section 21 has been formed in the sheet after ruling and cutting, the variation in quality of paper or of other conditions, have operated to vary the width of the sheets, so that when compiled in book form,

a ragged or unfinished appearance has been imparted to the completed book. In the present case, this is avoided by creasing and cutting the sheets at the same time. Also there is a saving in time in the production of sheets of this character when the creasing and cutting are performed at the same time with the ruling.

To permit the operation of the creasers 15 and knives 16, the belt 10 is depressed below the shafts 17 and 18, and is passed about the roller 22 to frictionally engage for driving the same. The roller 22 has at one end thereof, a pinion 23, as seen best in Fig. 2 of the drawings. The pinion 23 is engaged with a gear wheel 24, which in turn engages a second gear wheel 25. The gear wheel 24 is an idler, and is rotatively mounted on a bushing 27. The bushing 27 is rotatively mounted in a casing 28, the upper end where of forms a housing for the gear wheel 25. The'bushing 27 is bored eccentrically and forms an interior bearing for the shaft 18.

The shafts 17 and 18 are operatively connected in service by the equal gear wheels 29 and 30 the latter of which is rigidly mounted on the shaft 18. The shaft 18 forms an end thrust bearingto receive the bolts 31. The shaft 18 is tubular in form and has a reduced end extension 32. The extension 32 has a bearing in a bushing 33, likewise eccentrically bored.

As best seen in Fig. 3 of the drawings, the

. bushing 33 has lateral benches 34, wherein rest the ends of adjustment screws 35. The screws 35 engage perforations in brackets 36 set out from a twin bearing plate 37. The plate 37 forms bearings for the-bushings 33 and 38, the latter providing a bearing for the shaft 17. To form the receptacles for the bushings 33 and 38, the plate 37 has split circular ends contractibly connected by screws 39 and 10.

The purpose of the above construction is to permit the shifting of the shaft 18 sui'licient to free the ridges of the creasers 15 and the knifes 16, so that the same may be moved lengthwise of the shaft 17. It is by shifting the creasers 15 each relative to the other, that the width of the section 21 is varied. As shown in Fig. 1 of the drawings, the section 21 is the full Width of the creasers 15. Should it become desired that the section 21 be reduced in width, this could be accomplished by shifting either or both of the creasers 15, so that only portions thereof overlap to engage or mesh. After the shafts 17 and 18 are parted sufficiently to permit this lateral movement of the creasers, the "set screws 19 are released and the creasers moved to the desired positions. The set screws are then tightened and the shafts again drawn together to the service or working position. During the separation of the shafts, if it is desired the knives 16 and creasers 15 may be shifted laterally to avoid operation on the sheets of paper passing through the machine. The shifting of the shaft 18 above referred to is accomplished by rocking the bushing 33. It is obvious that if one of the screws 35 be manipulated to depress one of the benches 34 and the opposite screw 35 be manipulated to release the bench 34 with which it is engaged, the bushing 33 will be rotated in the plate 37 If, now, the pin 11 be extended through the bushing 27 and the shaft 18, the said shaft and its bushing is rotated with the bushing 33.

If the separation of the shafts is desired, the screws 35 are manipulated to rock the bushings 33 and 27, so that the thickened parts of said bushings pass to the upper side of the shaft 18 and end 32 thereof. This carries the center of the bearings of the said bushings away from the center of the bearings for the shaft 17. By moving the shaft- 18 and parts connected therewith away from the shaft 17 and parts connected therewith, so that the gripper rolls 20 release the paper, the ridges of the creasers are separated far enough to permit the lengthwise adjustment of the said creasers.

Claims:

An attachment as characterized comprising a conveyer belt for supporting sheets to be ruled; a plurality of guide rollers for deflecting said belt from the general level thereof; a plurality of shafts disposed trans verse said belt; means disposed on said shafts for engaging sheets when delivered thereto from said belt for transferring the same to said belt; and means for separating said shafts to avoid engagement of said sheets, said means embodying a plurality of bushings having eccentric bearings for said shafts.

2.
