SHEET-REGISTER.

I SPECIFICATION forming part of Letters Patent No. 671,377, dated April 2, 1901.

Application filed March 27, 1900- Serial No. 10,341. (No model.)

To all whom it may concerm- Be it known that I, OHARLEs GRANT HAR- RIs, of Niles, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Sheet-Registers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in means for effecting the side register of sheets of paper or other stock as the same are being fed to a printing or other machine.

The object of the invention is to provide simple and efficient means capable of being easily operated and which will insure the proper positioning of a sheet before it is taken up to be fed to the press.

The invention comprehends the employment of means for crimping or corrugating and holding each sheet of paper or other stock while crimped or corrugated against the top of a receiving-table and means whereby when the sheet is so crimped it will be bodily moved laterally to its line of travel to the machine until it is properly positioned to be fed forward. The idea of means includes, preferably, a groove in or on the table-top transversely to the line of travel, a rod or other suitable device for crimping the sheet by depressing it in the groove, and a sideregistering plate, said plate and crimping device being relatively adjustablethat is, the plate may be movedinto engagement with the edge of the sheet While crimped, or if such plate be stationary the sheet is moved bodily by moving longitudinally the depressing device or by imparting a like movement to a slide within the groove, between which and the said device the paper is located, thus bringing the edge of the sheet against the side-registering plate. The crimping device may be elevated when the sheet is taken up by the feed-rolls, and at the same time stops with which the forward edge of the sheet is caused to register will be moved out of the way. I

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a View in perspective, showing a portion of a printing-press equipped with the present improvements. Fig. 2 is an enlarged plan view with parts broken away. Fig. 3 is a longitudinal sectional view through a portion of the sheet-receiving table. Fig. 4 is a perspective view showing a modified form in which the strip in the table-groove is designed to be moved longitudinally. Fig. 5 isa similar view showing the arrangement employed when the depressing-bar is to be moved longitudinally.

Referring to the drawings, A designates the frame of a printing-press, parts only of which are shown.

While the improvements are indicated as applied to 2. Harris automatic press, yet the use or application of the invention is not restricted.

a is the type-carrying cylinder; at, the impression-cylinder; a the feed-rolls, and a one of the wheels of the train of gearing. (Not shown.) On the spokes of this wheel is a cam a in the form of a ring with disconnected ends between two of the spokes.

B is the receiving-table, which may be provided with tapes I), mounted on suitable rollers journaled in the table-top. In the upper surface of this table, at the forward ends of the tapes and at right angles to the line of travel to the press, is a groove or recess 1. This may be formed in the table-top or in a separate piece affixed to or set in the latter. Within this groove, adjacent to one ofits walls,is a bar 2,which is approximately square in cross-section, said bar extending throughout the length of the groove. In the balance of the space in the latter between the bar 2 and the forward wall of the groove is fitted a strip 3, extending the length of the groove.

0 is a plate forming a side-registering device, which extends across the groove at right angles thereto and is secured at any desired point to the bar 2, preferably by a removable screw passed througha slotted extension 3. In this plate 0 is an opening 4 to accommodate a'cross rod or roller 5, supported at its ends by arms 6, fast on a rock-shaft 7. This shaft is rocked just suflicient to raise the rod 5 so that it will release its hold on a sheet of on a shaft 9 and engaged by a cam 10.

paper by it held depressedin the table-groove. This may be accomplished by an arm of said shaft engaging a lever B, loosely fulcrumed In the form shown in Figs. 1 and 2 the side registering is effected by the lateral movement of the plate 0 through the longitudinal movement of bar 2, while in the forms shown in Figs. 3, 4, and 5 the plate 0 and its bar 2 remain stationary, the lateral movement of the sheet being effected according to the form shown in Figs. 3 and 4 by the longitudinal movement of the strip 3 and according to the modification in Fig. 5 by the longitudinal movement of rod 5. These movements to effect the side register may be accomplished by any suitable means. In Fig. l. I have shown a lever 11 connected by a link 12 to one end of bar 2, one arm of said lever being so bent as to be normally engaged by the cam on of wheel a'. When the space between the disconnected ends of this cam is opposite the end of the lever, the latter is moved by the tension of a spring 13 in such manner as to effect the inner lateral movement of the side-registering plate as the bar 2 is moved longitudinally. In Fig. 4B the lever 11 is connected directly to an arm 14, projecting from in Fig. 4, and for the same purpose the rod 5, Fig. 5, may be provided with small rings 17.

In practice it is necessary to arrest the forward movement of a sheet while and until it is positioned. For this purpose I employ stops 18 in the form of arms 19, having up turned ends projecting through openings in the table-top, said arms being fast on-shaft 9, which at one end carries an arm 20, a roller in the end of which is engaged by a cam 21. The cams 10 and 21 may be formed in one piece, with their contours so arranged that as the cam 10 eflects the elevation of the depressor-rod the cam 21 will cause the lowerin of the stops, thus permitting the paper to loe taken up and fed forward by the feedrolls a The operation is as follows: As a sheet is received from a feeder (not shown) it is carried forward by the tapes I), and passing over the groove and beneath the depressorrod, the latter being raised sufficiently for the purpose, the sheet advances until arrested by the stops 18. At this moment the rod 5 is lowered, causing the paper to be slightly depressed into the groove, thereby forming a crimp or corrugation therein transversely of the table. As this occurs the bar 2 and plate 0 are moved inward through the action of spring 13-, and while the upper forward edge of the bar will have frictional contact with the paper, which is still held depressed, it is insufficient to move the paper laterally against the resistance of the friction of rod 5 and the forward edge of the groove; but when the plate 0 strikes the side edge of the sheet it overcomes the friction thereon and carries the sheet laterally until properly positioned. The paper having been crimped or corrugated by being pressed in the groove, it is stiffened, while the corners or edges of the grooveand the slide-bar 2 act as guides to hold the paper in a perfectly rigid position as regards any displacement forward or back or any twist in the paper, thus making its lateral movement perfectly true and only so far as it is forced by the plate 0, the friction-rod and groove being sufficient to prevent any over movement from inertia or back movement in the return of slide 0 and its bar. Thus the sheet is held perfectly in position by the rod 5 until the feed-rolls'feed it forward to the press-cylinders. As this occurs the stops 18 are lowered, and at the same time the rod 5 may be raised from the groove, or this latter movement may be postponed if it is desired that the rod 5 assist to smooth out the sheet as it is being carried forward by the feed-rolls, in which event said rod will be free to rotate in its supporting-arm. According to the form shown in 3 and 4 the bar 2 and slide 0 remain stationary, the lateral movement of the sheet being effected by the longitudinal movement of the strip 3, while in the form shown in Fig. 5 the side registering of a sheet is accomplished by the longitudinal movement of the rod 5 while it holds the paper depressed in the groove.

The means employed for carrying out this invention are extremely simple, and the moving parts .are very light. The normal position of the latter is such that they interpose no obstacle to the free passage of the sheets in entering. By crimping or corrugating each sheet the paper is stiffened, making it possible to move up a close side register, and at the same time creases which may be in the sheet are removed, with the result that a closer side register is had with many sheets, which it would otherwise be impossible to obtain even if such sheet be positioned 'by hand, since when a sheet has a crease or fold it is liable to move a little one way or the other when engaged by grippers unless such crease 01' fold is ironed out in some way at the front of the sheet.
