2 Claims.

This is a division of my application for Patent Serial No. 187,375, filed April-28', 1927. The invention is shown as applied to one unit of a printing press, it being understood that sev- 5- eral units can be combined to form a more complete press, but this invention is not concemed with the way of combining them.

The principal objects of the invention are to provide improvements in the way of feeding the perfected web from the printing couples to the:

folder, including means for slitting the web and bringing the slit parts into a position, one over the other, and improved compensating rolls and adjustments therefor to be used for this purpose; to provide a set of adjustable turning bars and mountings therefor used in this part of the press; and to combine these features with an eflicient form of drag roll, propeller, and slitting means for originally slitting the web before it passes to the drag roll.

The inventionalso involves the combination of these several features with each other in; such a way as to provide a compact machine having the parts that have to be adjusted and attended to readily accessible so as to reduce the time lost in adjusting parts and render the press suitable for continuous use in newspaper printing plants.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to drawings in which Fig. 1 is a diagrammatic view of the printing couples showing above them the means for slitting the web and guiding it to the drag roll in accordance with this invention;

Fig. 2 is a side view of the slitting mechanism illustrated at the left hand side of Fig. 1;

Referring first to Fig. 1, I have shown the press, or rather a press unit, comprising means for feedthe accompanying 7this application July 15.

ing and perfecting the web and feeding the web through a set of compensating rolls after having first slit it, and then bringing the slit webs over the drag roll into the folder one over the other. It will be understood that these elements may constitute a complete press, but they can constitute an element of a multiple press for min a newspaper printing plant, in which case one folder would serve to take the product from a plurality of press units. 4

It will be seen that I have shown the perfecting printing couples delivering the web upwardly over a guide roll 82 on a part of the frame secured to the main frame above the printing couple.

The web passes to a slitter roll 83 and acted upon by a slitter 84 which slits it preferably in two in the middle to form two webs. This slitter is shown in Figs. 2 and 3 in the form of a circular rotatable cutter mounted on an arm 85 which is fixed to a shaft 86 mounted on the frame. The frame is provided with a stationary rack 81 having two teeth. Fixedly mounted on the shaft 86 is an operating handle 88 having a springpressed latch 89 adapted to be secured in'either of the notches in the in contact with the slitting rolls operative purposes or to hold it way as maybe desired.

The web being slit passes in two difierent paths, one directly to a compensating roll 90 and the other to a guide roll. 9|. The latter web passes back to a similar compensating roll 90 and the first named web passes back from its compensating roll 90 to another guide roll 9|. a loop in each web, the depth of which is regulated by the position of the compensating rolls. The latter web passes over a pair of turning bars 92. These turning bars, as will be understood, bring this web over laterally directly under the upper web so that they can be fed forward, one superposed over the other and practically registering with each other.

The compensating rolls 90 are alike. Each of them extends across the frame far enough to form a support for its own web or half web. The purpose is to adjust these rolls back and forth in the direction of the travel of the web to take up slack and secure the proper degree of tension. The adjustment in each case is provided for' by a hand wheel 93 on a shaft 94 which shaft is provided with a worm 95 adapted to turn a corresponding worm wheel on a screw 96. This screw passes through a nut 91 pivotally mounted on the frame. Consequentlythe turning of the hand wheel 93 will adjust the screw longitudinally,

83 as shown for back out of the rack 87 to hold the slitter.

Thisforms hand wheel 93 or carrying with it a frame 98 on which pensating roll 90 is Journalled.

It will be understood that there is a frame 90 with associated parts on each side of the machine. They slide freely on the frame as indicated in Fig. 5. The screw 96 is secured to'a hollow square shaft 99 into which telescopes a solid square shaft I connected with a shaft IM and adapted to be operated'through a bevel gear connection by another hand wheel I02.

A corresponding shaft IOI is operated in the same way by another hand wheel I02 for controlling the other compensating roll. The hand wheels I02 are located in fixed positions where they can be reached from the folder. It will be understood that each roll is adjusted by either I02 and that these are provided at different points for the convenience of the operator. The hand wheel 93 in each case moves along with the compensating roll and when moved far in is not perhaps so convenient for the operator. The hand wheels I02 are always in the same place, irrespective of adjustment. It is the movement of the compensating rolls bodily with their frames 98 that necessitates the telescoping of the shafts 99 and I00, which are connected with each one of the shafts I0 I.

The turning bars 92 are set in the usual way but are supported by brackets I05, which are mounted on longitudinal rods I06 constituting part of the frame. These brackets are provided with bolts I01 on which the end of each turning bar 92 is secured. Each bracket is provided with two projections I00 which are screw threaded to receive screws I09 which are set into the turning bars to adjust them exactly 45 and hold them in that position.

It will be seen that the brackets I are double handed so that the same bracket can be used either way around or for. a bar slanting in either direction. These brackets can be slid along the supporting rods I06 and the turning bars secured to them easily and readily attached and secured in either position as may be desired.

From the compensating roll or turning bars, as the case may be, the two webs are brought into contact, one over the other.

The web is delivered from the printing couples to the drag roll through a slitter and one of the slit webs is moved over by turning bars into a position in vertical alignment with the other.

the com- 2,008,568 The turning bars are adlustably mounted by means which can be reversed to turn them in the opposite direction if desired. The webs passing from the slitter to the drag roll are kept taut by compensating rolls which can be adjusted either from their ends or from a stationary position on'the frame.

These several features are combined with each other in such a way that the machine is compact and all parts are readily adjustable and time is saved for performing these operations. This is an important feature on account of the necessity of speed Although I have illustrated and described only one form of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is:-

I. In a printing press, the combination with a pair of web perfecting couples, of a roll over which the web therefrom is directed, a slitter adapted to slit the web in cooperation with said roll, means for turning one of the half width webs into a position in vertical alignment with the other, compensating rolls, each located in a loop in one of said webs and adjustable transversely to its axis to register the web, means for operating each of said compensating rolls from a point near the roll to move it along. and means in stationary position near the folder for moving each of the compensating rolls.

2. In a printing machine, the combination of a slitter for dividing the web into two parts, a pair of compensating rolls arranged in a loop in each half of the web to keep the same taut, a frame on which said compensating rolls can be moved bodily for that purpose, carriages movable along said frame, one carrying each of said compensating rolls, means on each carriage for moving it along, a shaft having a telescoping section connected with each carriage so that the shaft will be capable of being turned from a stationary in newspaper printing plants.
