I Application filed January 14, 1895. Serial No, 584,893. (No model.)

To aZZ whom it may concern: printed. By this means the offset-Web will Beit known that I, HENRYA. lVISE \VOOD, receive the combing and will itself never a citizen of the United States, residing at slide beneath the printed web.

This I00 50 separately from and independently of the is a very advantageous construction, as it mechanism for manipulating the web to he will allow the main web to run very easily and smoothly through the printing mechanism.

The combing of the first impression-cylinder is not so material and may be neglected, as the first impression-cylinder turns against a clean side of the web and not against a freshly-printed side of the web, as would be the case if no offset-web was used between the web to be printed and the second impression-cylinder.

I may use the same adjusting mechanism to adjust the length of a sheet printed on the main web and the feed of the offset-web, and one way of carrying this out is by the gearing shown in this case.

The printing-couples are geared together by gears 47, 48, 50, 49, 51, 52, and 53, as shown. A gear 54 meshes into gear 53, and gear 54: is driven from a gear 56, mounted on a shaft 55, which Iterm the main shaft of the machine. The gear 56 is driven by a pinion 57 from a power-shaft 58. The end of the shaft 55 is keyed, and fitting on the end of the same is a change gear and cam 59 and 60, preferably made in one integral piece, and from this changeable piece the entire web-manipulating mechanisms forboth the web to be printed and the offset-web are driven. The change gear and cam maybe varied by removing the nut 550.

A sweep 61, having an extending arm 62, is mounted upon a shaft 06 and carries an intermediate 64, which can be set by means of clamping device 63 to engage whatever sized gear is put upon the shaft 55. This intermediate engages a gear 65, also turning with which isa bevel-gear 07, which meshes with and drives a bevel-pinion 08, secured upon the shaft 69, mounted in

bearings

70, 71,

and 72.

On one end of the shaft 69 is arranged a bevel-gear 73, which meshes with abevel-gear 74 on shaft 75, arranged in bearings 76, 90, and 96, as shown. From this shaft, by means of bevel-gears 77 and 78 and gears 7 9, 780, and 80, the feeding-in device for the main web is continuously driven, and by means of

bevelgears

91 and 92 and gears 93, 94c, and 95 the feeding-in device for the offset-web is continuously driven. On the other end of the shaft 69 is arranged a bevel-pinion 81, which meshes with and drives a pinion 82, secured on shaft 83, mounted in bearings 71 and 84. From this shaft, by means of bevel-pinions 85 and 86 and gears 87, 88, and 89, the continuously-running feeding-outdevice for the main web is driven. Arranged on the shaft 75 is a bevel-pinion 7 G0, which drives a bevel-pinion 97, and by means of gears 98, 99, and the continuously-running feeding-out device for the offset-web is driven. Meshing with the gear 74: is a bevel-pinion 101, arranged on the end of the shaft 102, mounted in brackets 103 and 104, and arranged on this shaft is a bevel-pinion 105, which meshes with a bevelpinion 106, and by means of gears 107, 108, and 109 the rewinding device for the offsetweb is driven. The loopers 37 and 40 are mounted in common brackets 41, arranged in the ways 110 in the main frame, as shown. The arms 16 have suitable adjustable connections 111, to which arms 112 are connected. Bearing against the cam 60 is a roller 113, mounted in the arm 114 of the bell-crank lever 114 115. This bell-crank lever is mounted upon a shaft 123, which extends across the press and has an arm 115 arranged on the oppoiste side of the same, similar to the arm 115 shown, so that the loopers are operated simultaneously from both sides of the machine or squared. Also extending from the bell-crank lever is an arm 116, which connects by link 119 to a bell-crank lever 120 12l,mounted on a shaft 122, which bell-crank lever is attached to one arm 30. An arm 121 is preferably arranged on the back side of the shaft 122 and connected to the other arm 30, so that the feeding-out looper 27 will be operated from both ends or squared. A spring 117 is arranged between the arm 116 and a station ary point 118 and serves to keep the roller 113 against the cam 60, as shown.

The change cam and gear may be removed, if desired, and another cam and gear, as 560 570, may be substituted. By this gearing, which has been described at length, it will be seen that the entire web-manipulating mechanisms, both for the web to be printed and the oifset-web, are driven entirely from the change gear and cam, so that by changing one piece the length of the sheet to be printed is varied, and at the same time the proper action of the offset'web is insured.

It also will be seen that the means for controlling and intermittingly withholding the offset-web are entirely independent from the means for withholding or controlling the action of the main web, so that the strain put on the offset web will not'affect either the web to be printed or its controlling mechanism.

Many other arrangements of gearing may be made to carr T out the purposes of my in vention.

My invention may be applied to a press 111 which the web to be printed is withheld 01'111 which only one web or a portion of the web to be printed is withheld.

The details and arrangements herein de scribed may be greatly varied by a skilled mechanic without departing from the spirit of my invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination in a rotary printingpress, of controlling-means for intermittingly withholding the web to be printed, an oifsetweb interposed between the web to be printed and the second impression-surface and separate controlling means for intermittingly withholding the offset-web, substantially as described.

2. The combination in a rotary printingpress of controlling means for intermittingly withholding the web to be printed, an offsetweb interposed between the Web to be printed and the second impression-surface and separate controlling means for intermittingly withholding the oiisetweb so arranged that the web to be printed and the offset-web will move in harmony, substantially as described.

3. The combination with a web-printing press in which the web to be printed is intermittingly withheld, of an offset-web interposed between the web to be printed and the second impression surface, and means for controlling the oitset-web so that the same will move in harmony with the main web, consistingofcontinuously-running feeding-in and feeding-out devices and looping devices, substantially as described.

4. The combination with a web-printing press in which the web to be printed runs intermittingly, of an offset-web interposed between the web to be printed and the second impression-surface,means whereby the length of the sheet printed maybe varied and means whereby the offset-web may be adjusted to always move in unison with the web to be printed, substantially as described.

5. The combination with a rotary webprinting press in which the web to be printed is withheld during the non-impression period, of an ofiset-web interposed between the web to be printed and the secondimpression-surface and a single adjusting mechanism arranged to vary the length of the sheet that maybe printed and to adjust the movement of the ofiset-web so that the offsetweb will al ways move in unison with the web to be printed, substantially as described.

6. The combination with a rotary web printing press, of controlling mechanism for the web to be printed consisting of continuously-running feeding-in and feeding-out devices and devices arranged so that the main web may be withheld during a non-impression period, an offset-web interposed between the web to be printed and the second impression-cylinder, controlling mechanism for the offset-web, consisting of continuouslyrunning feeding-in and feeding-out devices and loopers, and a single adjusting mechanism adapted to vary the speed and action of the controlling mechanism of both the web to be printed and the oitset-web, substantially as described.

7. The combination with a rotary webprinting press, of gearing whereby the printing-couples will be continuously rotated, mechanism for withholding the web to be printed during a non-impression period, an offset-web interposed between the web to be printed and the second impression-cylinder, controlling mechanism for the offset-web arranged so that the offset-web may move in harmony with the web to be printed, and a single adjusting mechanism adapted to vary the length of the sheet printed and to adjust the action of the offset-web so that the same will always move in unison with the web to be printed, substantially as described.

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