DELlVERY MECHANISM FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent N o. 782,924, dated `February 21, 1905.

Application filed April 16, 1904-. Serial No. 203,438. i

To all whom t may concern:

Be it known that I, OSCAR RonsEN, a citizen of the United States, residing at New York, county of New York, and State of New York` have invented certain new and useful Improvements in DeliveryfMechanisms for Printing- Machines, 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 delivery mechanisms for printingmachines.

ln fast printing-machin'es-such, for instance, as a machine of the rotary type now employed for Web-printing-it is customary to deliver the sheets cut by the usu'al cuttingcylinders or other mechanism to cylinders,/

usually collecting cylinders, on which the sheets are held by pins on their cylinders'. In certain classes of printing, however, the use of pins is objectionable because of the perfo, rations left thereby in the margins of the sheets.- It is furthermore desirable in certain classes of printing'to deliver sheets unfolded and to do this in a manner which avoids smutting oroffsetting, this being particularly desirable inmachines where heavy cutwork is being printed. 'It is one of the objects of the invention to produce an improved delivery mechanism for web-printing machines in which the separated sheets are carried forward by grippers and delivered in an unfolded condition, the gripper mechanism running at the speed of the web, so that no acceleration of the sheets after cutting is necessary.

A further object of the inventionl is to produce an improved delivery for web-printing machines employing sheet-carriage mechanism' whereby the sheets are delivered fiat and without danger of smutting.

A' further object of the invention is to produce an improveddelivery for web-printing machines in which the webs are taken by a collecting mechanism employing grippers and after cutting are forwarded, the mechanism running at the speed of the web and including a plurality of sheet-taking devices, whereby the sheets are alternately sent in different directions and delivered unfolded.

, VA further object of the invention is to produce an improved delivery mechanism for Web-printing machines employing collectingcylinders provided with grippers, successive sheets beingtaken by the cylinders alternately and the collected sheets being delivered in an unfolded condition by a carriage-delivery mechanism. v

' With this and other objects in view not specifically here'inbefore pointed out the invention consists in certain constructionsand in certain parts, improvements, and combinations, as will be hereinafter described andv then more particularly set forth in the claims hereunto appended. f

Referring to the drawings, which form a part of this specification,l and in which like characters of reference indicate the same parts, Figure 1 represents in side elevation so much of the delivery mechanism of a printing-machine as is necessary for an understanding of the invention. Fig. 2 is a sectional elevation on lines 2 2 of Fig. l. A 1n the drawings, which represent a preferred embodiment of the invention, 1 indicates a frame in which the operating parts of the' mechanism are supported, the frame be- .ing of any suitable form and construction. The printing mechanism is not herein illustrated, a description thereof not being necessary for an understanding of the invention; but it may consist of a rotary printing couple or couples of any approved type.

4 rlhe printedweb indicated atW is forwarded by guides of any approved type-as, for instance, rollers 2-to the. cutting mechanism, which may be of any desired construction. 1n theY particular construction illustrated this cutting mechanism embodies the usual cuttingcylinders 3 4, said cylinders-being mounted upon shafts 5'6 and driven by gearing. which will be hereinafter referred to. vlf desired, a

being mounted on shafts 11 12. suitably sup-A ported in the frame. The cylinder 9 carries grippers 13, which may be of any usual type. Similarly the cylinder l0 carries grippers 14. 1n the operation of the mechanism the forward edge of the web issuing from the cylinders 3 4 is taken by one of the sets of grip? perse-as, for instance, the grippers 13-and carried onward, the cutting mechanism operating as usual after,y the forward edge of the sheet has been taken by the grippers. After cutting, the forward edge of the web, formed by cutting olf the web, is taken by the grippers 14, and when the cylinders referred to are, as they preferably will be, collecting-cylinders` this operation proceeds, successive sheets being taken by the cylinders alternately until the required collection is com- The cylinders may be driven in any suitable manner. As shown, there is provided a wayshaft 15, said shaft carrying a miter-gear 16, which meshes with a miter 17, mounted on the shaft 18, running across thf machine.

This shaft 18 is provided with agear 10', which meshes with the lower one of a pair of intermediates 20 21. The upper intermediate 21 is in mesh with a gear 220m the shaft 12 of the cylinder 10, this gear 22 being in mesh with the gear 23, mounted on the shaft 11 of the cylinder 9. An intermediate 24 serves to drive one of the cutting-cylinders, these being intergeared in any usual manner.

While thesheets mightbe delivered,whether collected or not, from the gripper-carrying mechanism in various ways, they will preferably be delivered by carriage mechanisms of the type usually employed with machines of the type known in the art as two-revolution cylinder-machines. .The particular type of carriage mechanism employed may be widely varied. The one selected for Ythe purpose of illustrating the invention corresponds in its essential characteristics to the construction illustrated in Patent No. 591,223, dated October 5, 1897. In the preferred construction two carriages will be employed, one for each collecting mechanism. As shown, the frame `is provided with ways 25, in which travel rollers 26, these rollers serving, through suitable means, to support side frame-pieces 27. These frame-pieces are connected at their forward endsv by a rod 28 vand also serve to support a roller 29. Mounted in the frame is a rod 30, said rod serving to support lingers 31,

Greases.

onwhieh the sheets are received when thecarriage is in receiving position. The rod 28 carries a'series of lever-arms 32, in which are mounted rollers rlhe carriages and carriage-operating mechanisms are duplicates and therefore only one is shown and derlhe presence of the second carriage is indicated, however, by a part of adriving y mesh with a gear 41, mounted on a shaft 42, i

extending lacross the machine, this shaft being carried in brackets 43, secured to the frame.

The shafts 42 'also carry gears 44, which are 1 in mesh with racks 45 on the carriages. It will be understood that as the crank-arms rotate the sectors are reciprocated,` and the gears 44, being driven in opposite directions, serve to reciprocate the carriage.

Means are preferably employed to insure the stripping of the sheets from the collectingcylinders. While this means may vary in construction, as shown, strippers ,46 are employed, these strippers being carried on shafts 47, extending across the machine. These shafts are Vpro-vided with crank-,arms 48 which are connected to cam-rods 49, the other ends of these rods being forked, as at 50, and carrying rolls- 51, which coperate with cams 52,' the construction being the `usual one. Preferably,y also, delivery-tapes 53 will be employed, these tapes being supported and driven in the usual manner. The crank-arms 37 are so set that when one of the carriages is in receiving position the other one will-be either in delivery position or intermediate the delivery and receiving position, according to the number of sheets to be collected. When one of the carriages comes into its receiving position, the stripper 46 is thrown in and the stripper, in connection with the tapes 53, causes the sheets to be delivered to the .supporting-fingers of the carriages. The gear 41 is then operated in the reverse direction fand the carriage is moved outwardto its delivery position. As the carriage starts on its rearward movement the-roll 29 is operated by a clutch mechanism not necessary to describe herein, but which is fully described iny the patent before referred to, and the pack of ros these chains passing over sprocket-wheels 56, mounted on short shafts 57, supported in bearings 58 on the frame and over sprocket-wheels 59, carried on a shaft 60, this shaft being suitablysupported in the'frame. This shaft 60 is provided with a worm-wheel 61, which is in mesh with a worm 62, mounted on a shaft 63, which may be driven in any suitable manner. As shown, a pawl-carrier 64 is mounted on this shaft, this pawl-carrier being operated by a link 65 from the cam 66 on the shaft 36, before referred' tor With this construction the table is lowered as successive sheet collections are deposited thereon, and after a table is filled a second one may be mounted in the chains to receive thesheets, the second one being lled as the rst one is removed.

Suitable joggers may be employed,- if desired, to even up the pile of sheets. In the construction shown side jogger-arms 67A are employed, these jogger-arms being mounted on shafts 68. End jogger-arms 69 operate on one end of the pile of sheets, these arms being mounted on shaft 70. This shaft 7 0 is driven by link 71 from the sector before described, intermediate driving means'of any suitable character being employed between the shafts 68 and 70. Additional side joggers 7 2 are also shown,these joggers being mount-f ed on the shaft 73, which is driven by a link connection 74 from the shaft 68. The operation of the construction will be clearly understood from the foregoing description. A specific statement thereof is therefore unnecessary. It will be seen that by the construction before described grippers may be employed which take successive sheets at the speed of the web, and, furthermore, by the use of collecting-cylinders and by duplicating the sets of carriages the speed at which the carriage is moved is lowered to adegree which makes it practicable to use this form of delivery in connection with web-printing machines. v

Changes and variations may be made in the mechanism by which the invention is carried into effect, and itis also to be understood that certain features of the construction in which the invention is embodied may be used independently of other features without departing from theinvention. to be limited, therefore, to the specific construction hereinbefere described, and illustrated in the accompanying drawings.

1. The combination with means for forwarding a web, of means for cutting sheets therefrom, devices whereby alternate sheets in an A unfolded condition may be forwarded in different directions, and a pair of delivery-carriages operating to deliver` the sheets unfolded, substantially as described.

2. The combination with means for forwarding a web, of means for cutting sheets therefrom, collecting mechanisms to which alternate unfolded sheets are delivered, and delivery-carriages cooperating with the collecting mechanisms and delivering the collected products unfolded, substantially as described.

3. The combination with means for forwarding a web, of means for cutting sheets therefrom, collecting-cylinders to which alternate unfolded sheets are delivered, and a pair of delivery-carriages coperating with the cyl- 'inders and operating to deliver the collected product unfolded, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
