PRINTING-PRESS.

Be it knownvthat I, FRANCIS MEISEL, a citizen of theUnited States, residing at Dor+ chester, in .thecountyof Suffolk andState of Massachusetts,.have invented a new and useful Printing-Press, of which is EL-SPGClfiCZtlZlOIl.

This, invention relates especially to that.

class of bed and platen printingpresses -which -are intended to print uponiwebs or strips of'paper. I

The especial objects of-thisinvention are to provide an improved, simple and efficient means for intermittently shifting an. I offset webto be used in connectionwith the. platen upon which-the web is :printed a secondtime;

Specification of Letters Patent. Patented M 17 1910. Application filed July 13,

B is the vertically. movable bed E which is g intended to carry a second type form, which i type form may be inked by any of the usual inking mechanisms, as I. These parts, as illustrated, are arranged as in a well-knowntype of press, and neednot beherein described in detail. The power for driving :the press is applied to the driving shaft 15 in the ordinary man- Fastened uponthe driving shaft 15 is a pinion which meshes with and drives a large gear-uponthewimpression shaft. 28.

Also secured upon the impression shaft 23 isv a gear meshing with an intermediate gear 22 'WlllClL drives a gear 16. secured upon :a

shaft having a crank-arm 17, which cranks arm 17 is adjustably connected by a link 18 to shiftan offset web as hereinaftendescribed. is provided-with crank disks having crankpins connected :bylinksQ to the swinging bed D. a

carrying a pawl 44. The pawl 44 as shown most clearly in Fig.6, isprovided with; a laterally' extendinglug .or finger a5 which is normally in-engagementwith a releasing disk 46 which has: a conical surface serving to hold the pawl up out of engagement with the ratchet wheel 47, which is fastened upon the shaft 'of the winding drum.

As shown in Fig.8, the releasing disk ,46

is mounted in a yoke at one end of a lever.

48. At'its opposite end, thelever 48 cooperates with a tooth 50 extending laterally :from a ratchet-wheel L9. The releasing disk ,is caused to move back when thetooth 50 is =notin-engagement withthe lever 4=8 by any.

convenient means,

As usual the impression shaft QS as for example, a spring 480. Cooperating with the ratchet-wheel 4:9

as shown in Fig. 2 is a pawl 51 carriedby a lever 60 adjustably connected to the sector 42 by a link The adjustment is secured by fastening one end of the link 53 in any one of a series of holes 61 on the lever 60, and the other end in adjusted position along a slot 62 in an arm on the sector.

By means of this construction the offset web will be intermittently shifted after a desired number of impressions have been printed. For example, if the ratchet-wheel 49 contains twelve teeth, and the connections for turning the ratchet-wheel are adjusted to advance the ratchet-wheel one tooth for each operation of the press, the laterally extending tooth of the ratchet wheel will be brought into position to swing the lever 48 and permit the turning of the winding roll by the pawl 4% whenever twelve printing operations have been completed. This enables me to shift the offset web to bring an entirely fresh section of the web into operative position whenever the desired number of impressions have been made.

The operation of the several parts has been so fully set forth in describing the construction that a description of the operation of the printing press as a whole is thought to be unnecessary.

I am aware that changes may be made in practicing my invention by those who are skilled in the art without departing from the scope thereof as expressed in the claims. I do not wish, therefore, to be limited to the constructions I have herein shown and described, but

IVhat I do claim and desire to secure by Letters Patent of the United States is 1. In a perfecting printing press having impression making means, the combination of an offset web, and means for shifting the web after a predetermined number of impressions are made to bring a new section of the off-set web into position, with a movable link and means movably connected therewith for adjusting the length of throw thereof to change the period of operation of the shifting means.

2. In a perfecting printing press, the combination of an off-set web winding roll, and means for operating the roll after a predetermined number of impressions have been made, with a link having its end adjustable for changing the period of operation, said operating means being inoperative until said predetermined number of impressions have been made.

3. In a perfecting printing press, the combination of an off-set web winding roll having a shaft, a ratchet wheel fixed on the shaft, a pawl for turning the ratchet wheel oscillatable about the shaft, means on the shaft for normally holding the pawl out of engagement with the ratchet wheel and for permitting the pawl to engage the ratchet wheel and turn the winding roll after a desired number of impressions have been printed, and adjustable means for operating said holding means periodically.

laterally movable releasing plate normally holding the pawl out of engagement with the ratchet-wheel, a lever for shifting the releasing-plate, and a second ratchet wheel for operating the lever to release the pawl whenv a desired number of impressions have.

been printed.

5. In a perfecting printing press, the combination of an offset web, and winding devices therefor, comprising a winding roll, a

ratchet wheel, a pawl, a laterally movable releasing plate normally holding the pawl out of engagement with the ratchet wheel, a horizontally swinging lever for shifting the releasing plate, and a second ratchet wheel having a cam or tooth for shifting the lever to permit the winding devices to operate when a desired number of impressions have been printed.

6. In a perfecting printing press, the com bination of an offsetweb and winding devices therefor, comprising a winding roll, a ratchet wheel, a constantly vibrating pawl having an extending lug or finger, a later ally movable releasing plate having a conical surface for normally engaging the finger of the pawl to hold the pawl out of operation, a horizontally swinging lever for shifting the plate, and a second ratchet wheel having a tooth or cam at one side for moving said lever to permit the winding devices to operate when a desired number of impressions have been printed.

7. In a perfecting printing press, the combination of impression making means, an offset web, a segment operatively connected with the impression making means to make an oscillation for every revolution, thereof, and means adjustably connected with said segment and operated thereby for shifting the web after a predetermined number of impressions have been made to bring a new section of the off-set web into position.

8. In a perfecting printing press, the combination with impression making means, of an off-set web, an oscillating segment, means connected with the impression making means for operating said segment, a winding roll, a pinion connected with said winding roll and meshing with said segment, and means operated intermittently by said segment for disconnecting said pinion from the winding roll and connecting it therewith.

9. In. a perfecting printing press, the combination with impression making means, of an off-set web winding roll, a pinion mounted to rotate independently of said winding roll, and means operated from the impression making means for turning said pinion once for each impression and for periodically connecting said pinion with the winding roll, the connections for periodically connecting the pinion with the winding roll comprising a pivoted arm of adjustable effective length, whereby the number of impressions made between operations of the -10 winding roll may be Varied.

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