MEANS FOR TURNING THE SHEETS FED T0 LINING OR OTHER MACHINES.

SPECIFICATION forming part of Letters Patent No. 743,477, dated November 10, 1903.

' Application filed November 3, 1902. Serial'No. 129,96 9- (No model.)

To all whom it may concern.-

Be it known that I, FRIEDRICH FoRsTE, a subject of the King of Saxony, and a resident of Leipzig-Lindenau, Saxony, Germany, have invented certain new and useful Improved Means for Turning the Sheets Fed to Lining or other Machines, of which the following is a description.

The present invention relates to machines for lining paper or for making slots or incisions in cardboard; and its object is to provide means for easily and conveniently turning the sheet being treated a quarter of a turn or round at right angles. This movement of the sheet is necessary in cross-lining or incase slots or incisions have to be produced at right angles to those already made. f

In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is a plan of the device; Fig. 2, a side elevation with the table in section; and Fig. 3, a front elevation, showing the table slightly broken away.

In the frame (1 a rotary disk (1 is horizontally disposed, having its upper surface substantially flush with a series of transfer-bands 2', adapted to pass over the said table. The disk or is mounted on a spindle I), supported in bearings 0, adapted to slide on cross-bars e of the frame, on which they and with them means of a screw-spindle fin the known manner. The bearing-frame cis provided with upwardly-extending arms 19 at each end, to which is fixed a guide-barq, suitably recessed so as to fit onto the surface of the disk aand to project beneath it at each side, so that the sheets carried along by the bands '1; will be prevented from passing under the said guidebar. and to, mounted at each end of the frame at. The bar e nearest the roll it carries hangerbearings g, in which is mounted the drivingshaft h, which may be rotated by any suitable means. A cord-roll Z or other suitable gear serves to drive the roll hand with it the The bands 0 are guided over rolls is 'v,

transfer-bands 2', while a second cord-roll or other gear 0, which is movable along the shaft 71 by a groove-and-feather attachment to follow any adjustment of the disk at, rotates the cord-roll or gear m of the spindle b and with it the disk at.

A laterallyextending spindle r is mounted in the guide-bar q and provided with 1oosely running friction-rolls s 8, adapted to run on a radius of the disk at at right angles to the guide-bar q.

The device operates in the following manner: Assuming the sheet to have been lined or slotted in one direction and to be passing along on the bands i in the direction of the arrow, Fig. 1, to be cross-lined or slotted and assuming the disk a to rotate in the direction of the arrow in Fig. 1, the sheet passes along the bands with, say, its longitudinal edge con tacting with the guide-bar. On crossing over the disk a it'will come under the friction-rolls s 8. Now the speed of the outer of the two rolls is greater than of the inner one, owing to the greater peripheral speed of the disk at, and thus as the sheet passes under these rolls the greater speed of the outer roll will slew it round at right angles during its passage over the disk at, so that on leaving it the said sheet will lie with its cross edge against the guidebarq and will be in position to be cross-lined or slotted, as will be readily understood.

I claim as my.invention 1. In a device for turning sheets of paper, card or the like being fed to a lining or other machine, at right angles to their direction of motion, the combination of a horizontally-disposed disk mounted to rotate immediately underneath the transfer-bands in the path of movement of the sheet, a guide-bar for the sheet extending over the surface of the said disk, a spindle extending laterally from the said guide bar and having friction-rolls mounted thereon to run on the said disk at difierent distances from the disk center substantially as described.

2. In a device for turning sheets of paper, card or the like, being fed to a lining or other machine, at right angles to their direction of motion, the combination of a horizontally-dissaid disk at different speeds substantially as 10 described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

FRIEDRICH FGRSTE.
