HENRY F. BECHMAN, OF BATTLE CREEK, MICHIGAN, ASSIGNOR TO DUPLEX PRINTING PRESS COMPANY, OF BATTLE CREEK, MICHIGAN, A CORPORATION OF MICHIGAN.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed May 14. 1907. fierial No. 373.665-

To all whom it may concern:

Be it known that I, HENRY F. BEOHMAN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Folding Mechanism for Printing-Presses; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part-of this specification.

This invention is an improvement infolding mechanisms for printing presses and is particularly designed to be used in connection .with rotary web-printing newspaper presses. Its object is to enable the folder to deliver newspapers folded either to half-size or to quarter-size, at the will of the operator, and for this purpose the invention consists more particularly in the novel construction and arrangement of the cutting cylinder, folding cylinder and second-fold rolls, whereby the papers can be delivered by the second-fold rolls either to a receiver for papers folded to half-size or to a third set of folding devices by which the papers may be folded to quarter-size.

In the present invention the cutting cylinder and the second-fold rolls are mounted on adjustable supports which are pivoted axially of the folding cylinder, so that the cutting cylinder and second-fold rolls can be adjusted to different positions-peripherally of the folding cylinder so that the papers can be delivered either folded to halfsize or to quarter-size, as desired. By this arrangement the second-fold rolls are always at the same distance from the cutting cylinder, and the severed sheets travel the same distance from the cutting cylinder to the second-fold rolls in either position thereof.

The invention will be fully understood from the following description in connection with the drawings in which certain well known parts are simply diagrammatically shown; but the illustration and description will enable anyone skilled in the art to readily construct a folder embodying the invention.

In such drawingsFigure 1 is a detail end elevation of such a folder the frame being partly broken away showing the second-fold rolls in position assumed when the folder is delivering pa ers folded to half-size. Fig. 2 is a vertica section through Fig. 1, showing the parts adjusted to produce papers I folded to quarter-size. Fig. 3 is a plan View. Fig. 4 is a side elevation of Fig. 1.

F is a former over which the web is led from the printing mechanism between the

first fold rolls

1 and 1 located at the a ex of the former by which the web is folded ongitudinally upon itself before being passed to the cutting cylinder. Over

rolls

1, 1% the web is led between cutting cylinder 2 and folding cylinder 2, the latter being provided with rotary tuckers 2 and collecting pins 2, as usual in such devices. In this instance the cutting cylinder 2 instead of being journaled upon the fixed frame has its bearings in hangers 4 which are pivoted axially of the folding cylinder 2 and can be adjusted so as to'move the cutting cylinder 2 around the periphery of the folding cylinder from the position shown in Fig. 1 to the position shown in Fig. 2. The hangers 4 may be connected by tie-rods 4%, and are provided on their upper sides with segments 4 which mesh with gears 4 on a cross-shaft 4 which can be operated by a wrench or crank (not shown) applied to itsouter end so as to adjust the cylinder 2 to either position desired. And when so adjusted the hangers can be fastened securely in position by bolts 4 which are tapped through the -side frames into the hangers as shown in Figs' 3 and 4, said bolts being removed when the hangers are to be adjusted.

On the hangers 4 and at 90 degrees (or any other desired angle) removed from the cylinder 2 are journaled the

second-fold rolls

3 and 3 which are adapted to fold the severed papers to half-size. The rolls 3" and 3 may be intergeared as shown at 3 and may be driven by a gear 3 on one of the rolls meshing with a gear 2 on cylinder 2, so that the second-fold rolls will be driven in proper speed relatively to the cutting and folding cylinders.

The

cylinders

2 and 2" may have intermeshing gears as shown at 2 2 and cylinder 2 may be driven by gears 2 2, 2 as indicated in Figs. 1 and 4.

The pins 2 are mounted on rock-shafts 2, as usual, said shafts being controlled by a pin-cam 2 at one end of cylinder 2, said cam being fastened to the adjacent hanger 4 by bolts 2 or in other suitable manner, so that the pin-cam has a fixed relation to said hangers. Otherwise the construction of the pins and pin-cams and their mode of operaisms and needs no detailed explanation.

Below the folding cylinder 2 is a stacker which may be constructed as usual with receiving fingers 6, a rotary fly 6, and endless delivery belts 6 and when the parts are adjusted in the position shown in Fig. 1,

papers folded to one-half size will be discharged from the

second-fold rolls

3 and 3 onto the carrier 6 At one side of the folding cylinder 2 is a third folding device which preferably comprises

folding rolls

8, 8 which may be arranged at right angles to the cylinder 2, and between which papers may be tucked by a blade 8 indicated in the drawing and operated in the usual manner. Below the

folding rolls

8, 8 is a stacking device which may comprise a rotary fly 9 and endless carrier9 which runs at right angles to the carrier 6*. When the cutting cylinder 2" and the

rolls

3, 3 are swung to the position shown in Fig. 2, the papers will be discharged from the

rolls

3, 3 to this third folding device, and thereby they are folded to quarter-size and delivered onto the carrier 9 In operating this folder, if it is desired to have it deliver papers folded to half-size only, the hangers are swung to bring the cutting cylinder 2 and

folding rolls

3, 3 to the position indicated in Fig. 1, in which position the sheets of paper after being severed between the

cylinders

2 and 2 are caught by pins 2 as usual and carried around on the cylinder 2 until their centers come opposite the

rolls

3, 3 then the paper is tucked between the

rolls

3, 3 by the action of one of the tucking blades 2 and the papers are discharged onto the carrier 6 folded to halfsize and are delivered as usual. If now it is desired to fold the papers to quarter-size, the hangers 4 are adjusted to the position indicated in Fig. 2, so as to move the cutting cylinder 2 to a position below the folding cylinder 2 and move the

rolls

3, 3 to a position intermediate the folding cylinder 2 and the

third-fold rolls

8, 8 In this position there will be a somewhat longer lead of the web from the

rolls

1, 1 to the cutting cylinder 2, but there will be no longer travel of the cut sheet from cylinder 2 to the

second-fold rolls

3, 3? and the papers will be discharged from

rolls

3, 3 to the third-fold rolls or

devices

8, 8 by which the papers will be folded to quarter-size and discharged from

rolls

8, 8 onto the carrier 9 When shifting the parts from the position shown in Fig. 1 to that shown in Fi 2, or vice versa, the gear 2 may he slipped out of mesh, so as to allow the folding cylinder 2 to turn on its axis to the extent of the swinging movement of the cylinder 2 and second-fold rolls, so that the collecting fingers and tucking blades will not get out of time with their respective cams which turn with the hangers; after the hangers are adjusted and fastened the slip-gear can be replaced.

By the aforesaid construction and arrangement of parts, only one set of mechanisms is required to operate the folding tucking and collecting devices, and the operator merely has to remove bolts 4" and slip-gear 2 when making the shift from half-size to quartersize deliveries.
