SHEET-REGISTEBING DEVICE.

Specication of Letters Patent.

Original application led January 2, 1907, Serial No. 350,516. Divided and this application tiled January To all whom 'it may concern:

Be it known that I, LEWIS of America,

and a resident of the city of Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Sheet-Registering Devices, of which the following is a specification.

This invention relates to sheet registering devices such' as used in connection with printing or other machines.

The subject matter of this invention is divided out from an application for improvements in printing machines, tiled by me J an. 2, 1907. Ser. No. 350,516. The object of this invention is to provide a device for registering sheets in a predetermined position in such a manner that the sheet may be subsequently acted Vupon by a printing or other mechanism.

The particular features reside in the novelvnmnner in which the sheet is side registered and the means for supporting and moving it, the particular object being to construct this mec anism as simply and effectively as possible and to provide means, throu h which the side register can be change instantly from one side 'to the other, this in turn necessitatin novel and useful improvements in the met od of transmitting power to the registering mechanism. l

The detailed construction is set .forth in the following description and 'the novel features pointed out in the claims, while the preferred form is illustrated in the accompanying drawin which, for the purpose of this disclosure, s ows thisregistering mechanism as illustrated and described in the application above cited, though it will be clear that this device may be used in connection with other machines than printing presses.

Inthe saiddrawing: Figure 1 is a side elevation of a registering device embodyin myyinvention. Fig. 2 is a plan view thereol In the present instance, the reference nuineral 1 indicates a portion of the frame of the machine to which my invention 1s attached, 2 indicatesa supporting bracket, while 3 denotes the side frames.l These si'de frames are preferably integral with the piece 4 which connects said side frames and which forms a disk 5 in the center which rests on the bracket 2 and is pivoted thereto by the of this invention 1908. Serial No. 411,246.

bolt 6 having lock nuts '7. In other words the frames 3 and piece 4 form a U-shaped centrally pivoted bracket.

Between the side frames are mounted rollers 8 with just enough space between them to permit them to rotate. These rollers are all driven in the 'same direction, indicated by the arrows, from shaft 9 by the following means: The said shaft 9 carries a gear 10 which meshes with a pinion 11 on the shaft l12 of that one of the rollers 8 which in the drawing is indicated by 13. The shafts of all the rollers project through the one side frame as clearly seen on Fig. 2

and the driving means are mounted outside said side frame. On the shaft of each roller S and the roller 13, is mounted a friction roll. (or pinion) 14 and the motion is transmitted-from the roller 13 to the rollers 8 by means of the intermediate friction rollers (or pinions) 15 mounted on studs outside the frame. In this manner all the rollers are rotated in the same direction when power is applied to shaft 9.

A side guide as 16 is provided which is adjustable by means of slots 17 and bolts 1S. In this instance only one side guide is shown but it will be understood that a similar guide for the opposite side lwill be provided. In the present instance the sheets are supposed to be fed from a primary feeding mechanism containing the feed rolls 19, 19, but it is obvious that the sheets may bc fed by hand if desired. A- plate as 20 is provided onto which the sheet moves and abuts the register bar 21 having the stop 22. This pate is fixed either in the manner shown by means of the brace 23 or otherwise, build of the machine.

The shaft 9 is journaled in ears or lugs 24 which arise from the disk 5 and in the center this shaft carries a pulley (or gear) 25 driven by belt (or chain). 26 or other suitable means constantly in one direction, receiving the power from some shaft on the machine to which my device is attached.

It will be understood that the register stop bar moves periodically out of the way of each sheet to permit the same to be transferred from the plate 20 by means of grippers or other mechanism. There will\ preferably be a slight distance between the plate 20 and the stop barl to permit of a depending upon the by grippers orsimilar devices, or the table this purpose. v

The operation of this device is as follows: Suppose for `the sake of illustration that it is desired to register the right side of the sheet. Inthis ease the register tablethat is the layer of rollers in their supporting frameis turned tothe right as shown in Fig. 2 and locked firmly in this position by means of the lock nuts. either placed on the table by hand or preferably fed thereto by a` primary sheet feeding device and are conveyed toward the register stop bar by the rotation of the rollers. Before reaching the stop bar, however, the sheet is crowded against the side guideu in this case the right guide-and this crowding or conveying is due to the turning ofthe may be provided with cut out portions foi register table around its central pivot. In

i between the two edges 1s such thatv said the one or is automatically other words, the sheet is moved in a diago-v nal path until its edge registers with the side ot' the side guide, after which it moves along said guide until its forward edge abuts the stops on the stop bar. Next, this latter element is moved out of th'e way'by suitable means such as disclosed in the ap plication above referred to, and the sheet is finally removed. In this manner each sheet placed in the same position previous vto its further manipulation 'by the machine and the object of this invention is accomplished.

From the foregoing it will be unjderstood that the driving power must be applied centrally, because at any other point of the device there is too much deviation from the straight center line oi the device to permit of successful driving. And this will further be emphasized by an inspection of Fig. 2, from which itis seen that all other points of the device swing in quite anarch around the center.

IfV itis desired to registerto the left, the.

table is swung to the left and locked and the side guide changed. -And it should be kept inv mind that the turning of the table can be nicely adjusted to' suit any kind of paper.

rlfhe plate 2O is provided with the two edges 27 and 28 at an angle to one another.

AThe edges are beveled as shown in Fig. 1 so as to overlap the last roller and the angle edges are substantially parallel to the axis of the rollers when the same are turned to other side respectively.

The sheets areA evoke@ 1: i

A sheet registering device comprising a centrally pivoted frame, a layer of rollers j ournaled in said frame, means for rotating said rollers constantly in one direction, side registering means carried by said frame,

and a plate adjacent said rollers having a plurality of beveled edges at an angle to one another on the side nearest the rollers.
