SPECIFCATON forming part of Letters Patent No. 650,542, dated May 29, 1900. Application filed October 6, 1899. Serial No. 732,765. (No model.)

To all whom it may concern:

Be it known that I, THOMAS M. NORTH, a subject of the Queen of Great Britain and Ireland, residing at New York city, county of Kings, and State of New York, have invented certain new and useful Improvements in Associatin g Mechanism, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in devices forassociatingmoving products in web or sheet form-such, foi-instance, as the products of printing-machines.

It is frequently necessary in the formation of products having an odd number of pliesas, for instance, in the production of newspapers, where it is desired to make a product having six, ten, or fourteen pages, orvany other number of pages which is not a multiple of four-to assemble with a moving web or webs, which areto be cut and folded to form two plies or a multiple of two, a short section, which is to form a single ply of the folded product, the said single ply in a newspaper forming two pages of the paper. The web from which this sheet is cut necessarily moves through 'the machine at a slower rate of speed than the web or Webs with which it is to be associated, and in newspaper-work usually at half the speed. Devices have heretofore been used for taking a sheet cut from the slow-speed web and bringing it up to the speed of the rapidly-running web, so that it may be properly registered and associated with said web. All these devices have, however, been operated so that the sheet whichl is moving at slow speed has had its speed instantly increased at some point in the operation of the transferring means from the slow speed to the high speed. The result of this has been that the sheet has been subjected to a great strain by the sudden change of speed, and, furthermore, the devices by which the product is handled are liable to act unevenly on the product, and the results are exceedingly unreliable'. It is of course necessary, and 'especially in handling printed sheets, that all devices of this sort shall operate so that the associated sheet shall be always brought into exact register with the web or sheet with which it is to be associated. The deviceswhich have been heretofore used for this purpose have been particularly unreliable in lthis respect.

' It is the object of this invention to produce a mechanism by which a product running at a given speed may be associated with another product running at a different speed, and usually at a higher speed, said mechanism operating to take the product at its slow speed and bring it gradually up to the speed of the product with Whichit is to be associated.

With this and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combinations to be hereinafter described, and fully pointed out in the claims hereunto appended.

In the accompanying draWings,Which form a part of this specification, and in which like characters of reference indicate the same parts, Figure l is a sectional elevation of the cutting and folding cylinders of an ordinary web press and the improved transferring mechanism by which a sheet running at a slow speed may be associated With a web running at a higher speed. Fig. 2 is an end elevation, partly in section, of the construction shown in Fig. l. Figs. 3 and 4 are detail sectional elevations, on an enlarged scale, illustrating the devices employed for operating the transferring mechanism.

Referring to the drawings, which illustrate one embodimentof the invention, 1 indicates v i the folding-cylinder of an ordinary web-printing machine, said cylinder being mounted on a shaft 2, located in suitable bearings in the frame F of the machine. This folding-cylinder is provided with the usual cutting-blocks 3 and folding-blades 4, these devices being of any usual or preferred form. The cylinder is further provided with any suitable form of sheet taking and retaining devices. These devices preferably consist of f sets of retaining-pins 5, said pins working through-apertures in the cylinder and being controlled-by rock-arms 6, mounted on shafts 7. The shafts are j ournaled in suitable ears 8 and have projecting arms 9, preferablyprovided with friction-rollers lO, said rollers being arranged to contact with a suitable cam ll, mounted on the frame, the function of which is to with- IOO draw the pins into the cylinder at suitable times. The pins are thrown forward by means of spring-controlled rods 12, which are connected to arms 13 on the shaft 7. This being an ordinary construction, the springs have been omitted from the drawings.

Cooperating with the cylinder 1 is a knifecarrying cylinder 14, said cylinder carry-ing a knife 15, which cooperates with the cuttingblocks 3, before referred to. The cylinders 1 and 14 constitute the form of web-forwarding mechanism which it is preferred to use, though other forlns of Aforwardin g mechanism might be'employed. 16 indicates guide-rollers by which a web or a series of associatedwebs are led to the cutting-cylinders 1 and 14. i These guide-rollers 16 maybe the drawing-off rolls of a longitudinal folder or they may be simply guide-rolls, as shown. At 17 are indicated a pair of folding-rolls, with which the blades 4 cooperate to fold the product off the cylinder l.

The present machine is designed to associa-te with a web or webs running at full speed a sheet which is cut from a web which is printed by a machine running at half-speed, the pu-rpose being in the machine shown to make a ten-page paper, in which eight pages will be furnished by the two Webs WIV and WV', shown as running through the guide-rollers 16, and the other two pages will be formed by a sheet cut from the half-specd web NVQ and associated with the two webs referred to by the mechanism to be hereinafter described.

The half-speed web V72, which comes from any suitable form of printing mechanism, is shown as being forwarded by guide-'rollers 18. From the guide-rollers 18 it is delivered to a pair of cutting-cylinders 10 and 20. The cylinder 1'9 is provided with the usual form of knife 21, said knife cooperating with the blocks 22, carried by the cylinder 20. The cylinder 2O is provided with any suitable form of sheet taking and retaining devices*as, for instance, the usual sheet-taking pins 23, said pins being control-led in an obvious manner by means of a stationary cam 24.

The cutting-cylinder 20 is mounted on the shaft 25 and may be driven in any desired way. In the machine shown it is driven by a gear 26. (See Figs. 3 and 4.) The gear 26 meshes with a gear 27,'which is mounted on a stud 28, said stud being supported in a bracket or frame 29, suitably bolted or otherwise secured to the frame F of the folder. The gear 27 has connected to it, preferably by being keyed to its hub, a gear 30,which gear meshes with a gear V3l, mounted on the shaft 2 of the folding-'cylinder 1. The gearing just described is arranged in the machine shown so that the cylinder 20 will be driven at half the speed of the folding-cylinder 1, or, in other Words, at the speed of the incoming halfspe'ed web VW. It may be further remarked that While the gearing described is a'conven.-

' ient and ready means for driving the said cylinder 2O anyother suitable or desired form of gearing may be used.

It being borne in mind that the cutting and folding cylinder 20 is running at half the su rface speed of the folding-cylinder 1, it will be readily understood that the sheet which is taken therefrom and which is to be delivered to the foldingcylinder l must be brought up to the speed of said cylinder. Vhile any form of device which will take the sheet at the speed of the cylinder 2O and bring it up by a gradually and constantly increasing movement to the speed of the cylinder 2 may be used, the mechanism preferably employed is as follows: Interposed between the cylinder 2O and the cylinder 1 is a transfer-cylinder or sheet-carrier This transfer-cylinder or carrier is mounted on a shaft 33, which finds its bearings in the frame F of the folder. The shaft 33 is provided with a crank-arm 34, said arm being secured thereto in any suitable manner and preferably carrying an antifriction-roll 35. The shaft 33 is set eccentric to the stud 28, on which are mounted the gears 27 30and which therefore forms the axis of revolution of these gears. The gear 30 carries on its side a slotted operating-block 36, said block being secured to the gear in any suitable manner, as by bolts 37. The slot in the block 36 is engaged by the roll 35 on the arm 34, and inasmuch as the stud on which the gear 30 rotates and the shaft 33, to which the arm 34.- is secured, are out of line 'witheach other the gear will operate to transmit to the shaft 33 a constantly-varyingAmotion. vIn the machine shown the parts are so arranged that the greatest speed of thetransfer-cylinder carried by the shaft 33 will be twice its slowest speed and the slowest speed will be equal to the speed of the cutting-cylinder 20. The transfer-cylinder 32 is provided with any usual form of sheet-taking devices-such, for instance, as vpins 38, these pins being mounted `on a rock-'arm 39 and controlled from a fixed cam 40. It is obvious from what has been said that if the pins on the cylinders 2O and 32 are properly arranged the pins 38 on the cylinder 32 will take the sheet from the pins 23 on the cylinder 2O when the cylinders are moving at the same rate of speed. The cylinder 33 after its pins take the sheet has its speed gradually and constantly increased during the next half revolution by the crank mechanism which operates it, so that by the time the pins 38, carrying the sheet, meet the pins on the cylinder 1 they will be moving at the same surface speed as the pins on the cylinder 1, and consequently the sheet can be transferred from the transfer-cylinder to the cylinder 1 without any sudden strain orjerk. After the sheet has been taken by the pins 5 on the cylinder 1 it will be carried onward and associated with the webs WV V72 in the Ausual manner, the said webs being cut by the knife 15 on the vcylinder 14 and folded IOO IIO-

0E by the blades 4, which cooperate with the rolls 17.

It is to be understood, of course, that the' mechanism by which the invention is carried into ecct may be widely varied. Thus while vthe invention is shown in connection with a machine in which the forwarding mechanisms for advancing the products are cylinders it is of course understood that the invention is capable of use with any other suitable form or forms of forwarding mechanism. The invention is not therefore to be limited to the specific mechanism which has been described and illustrated, but it is to be understood as embracing all forms of mechanism in which a transferringr device is used that takes a product from a forwarding mechanism ru'nning at one speed and delivers it to a forwarding mechanism running at another speed, the transferring device being arranged to run at varying speeds, its speed at the time it takes the product being equal to the speed of the forwarding device which then has control of it and its speed at the time it delivers the product being equal to the speed of the forwarding device to which it delivers it. Vhile also the invention is particularly designed for use with printing-machines, it might be used in other relations.
