Application filed September 28,1900. Serial No. 31,388. (No model.)

T0 all whom it may concern:

Be it known that I, GEORGE P. FENNER, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Sheet-Delivery Apparatus for Printing-Machines, of which the following is a specification.

In United States Letters Patent No. 335,066, of January 26, 1886, is set forth a delivery apparatus by which a sheet is delivered printed face up. By a suitable arrangement or attachment the delivery can be made with the printed face of the sheet down. Y

The reversing attachment formingthe subject of this invention is set forth in the following specification and claims and illustrated in the annexed drawings, in Which- Figure l is a side elevation of a delivery apparatus. Eig. 2 is a plan view of Fig. l. Fig. 3 is a detail view enlarged. Fig. 4 is a section along so Eig. 2. Fig. 5 is a section along @j y, Fig. 2. Eig. 6 is a section along .e a, Fig. 5.

In said patentis mentioned a printing-press frame A, with type-bed C and impressioncylinder B, as also the carriage G, with'rollers l-I I-l and the tapes O running about these rollers and about rollers I-I2 H3 on the frame. The manner in which the tapes deliver sheets on receivingeboard R is set forth in said patent and need not be here detailed. The carriage can be reciprocated by suitable means, as shown in said patent or in United States Patent No. 506,990, of October I7, 1893. The carriage is provided with a sheet-feeding roller a, Fig. 4, and with pressure-rollers b, and a sheet fed out between these rollers and bent `or reversed by the curler or conductor-iin gers c will be turned or delivered face down. To the shaft of roller a is secured or feathered a gear d, which when pushed or set to outward position, as in Eig. 2, will run on rack e, fixed to frame A. When the carriage runs forward or away from cylinder B, the roller a has its top or sheet-supporting portion also rotating forward, but at increased speed compared to the speed of the carriage. During such forward stroke the pressure rollers or disksbrest on roller a, so that a sheet grasped between these rollers is fed to guide c. Dura nose z', whose hub is mounted on roller or on a gudgeon forming part of this roller. This nose fi, with its hub and its tail j, can be cast in one piece, and in the example shown might be compared in the manner of mounting to a lever of the first class. The tail j extends between two fixed and suitably-spaced pins or stops k. When the tail j swings to contact with lower stop 7c, the nose t, with arm h, and wheels b are raised to clear or be out of touch with roller a. On nose t' dropping or tail j resting against upper stop 7c the wheels b fall to engagement with roller a. The pins 7c thus form stops limiting the swing of tailj and nose i to the required degree. The hub of nose ris of such size or its opening of such diameter as to sit loosely about the gudgeon of roller a; but said hub is seated between two friction or clutch pads or cheeks l, Fig. 6, which feather, or at least one of which feathers or slides, on the roller-gudgeon, so as to rotate with the roller, and a spring m tends to pressthese clutch-cheeks toward one another to grip the interposed nose t'. As the carriage travels forward the corresponding forward rotation of roller a and clutch-pieces Z swings nose e' downward until tail j is arrested by upper stop-pin k. The clutch Z thus keeps rotating and rubbing against the nose-hub, while such nose stands still, being in sufficiently low position for wheels o to have dropped to active position. On the return of the carriage and the backward rotation of roller a to lift nose 1l until arrested by lower stop 7a the rollers o are raised or in idle position.

It has also been found practical or simple to mount the sheet-reversing guides of on shaft g. In such case it is true the guides c rise somewhat on the return of the carriage and drop somewhat on the forward travel of the carriage; but this has not been found to in- IOO terfere with the desired working or reversing action of the attachment. The hubs of guides c being slipped onto shaft g, such guides can be set or adjusted to the required dip or angle, and thus fixed on the shaft by screws or fastenings n, and it can here also be noted that if the guides c are to be left idle the screws 'n have only to be loosened and the free ends of the guides swung up sufficiently high and there fixed by retightening the screws, so that these guides do not touch a sheet leaving the carriage or tapes. The attachment can thus be readily set for delivering a sheet either reversed or unreversed, as desired. lVhile this 'mounting of the guides is simple and practical, it is of cou rse self-evident that the invention is not limited to the exactconstructionshown. Thearrangement set forth, however, possesses certain advantages. It can be attached to carriages or deliveries being made for the market or even to those which are already in use, if such attachment should be called for, and if to be dispensed with such attachment can be readily left off or dismounted or set out of action.

The shaft L, Fig. l, is shown with an arm L fixed thereto. The crank-arm L2 is not keyed or fixed to shaft L, but is adjustable or has a pin-and-slot connection L3 L4 with arm L. This crank L2, by rack L5, actuates the driving-gear engaging rack M on top of reciprocating carriage G. By the adjustment L3 the crank and rack L5 can be set so that, for example, the leading edge of a sheet coming from cylinder B can reach conductor or guide c at different moments in the travel of the carriage. Say the crank L2 is set so that the carriage does not start forward until the sheet has had its leading edge fed forward some distance from between cylinder B and Wheel or roller P. The sheet will thus, as it might be expressed, have a certain start over the carriage.

The device has been found to Work Well, as follows: The leading edge of the sheet having been run forward some distance (say two or three inches, for example) of tape-carrying roller H2, and the carriage then starting forward with the sheet supporting or top stretch of the tapes, then on the return of the carriage the sheet standing still will come to lap with its leading part somewhat over onto roller a. The carriage now again starts forward andthe wheels b having dropped onto roller a such overlapping sheet is run forward between such wheels and roller and reversed by guide c onto the receiving-board. As seen in Fig. 4, rearwardly -extended guides o, applied to prevent the leading edge- H. As this tape-roller H now rotates or stands still, the roller o; does likewise.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a delivery apparatus for printing-machines, the combination of a reciprocating carriage, tape-rollers mounted thereon, tapes carried by said rollers, delivery feed-rollers mounted on the carriage and operating to grasp and deliver the sheets fed thereto by the-tapes, and reversing-guides carried by the carriage and arranged to intercept the sheets as they are fed from the delivery feedrollers and turn them face down, substantially as described.

2. A delivery apparatus comprising a reciprocating tape-carriage and tape-rollers, sheet-feeding rollers orwheels on the carriage, and reversing-guides in the path of a sheet moved by said feeding-rollers substantially as described.

3. In a delivery apparatus for printing-machines, the combination of a reciprocating carriage, tape-rollers mounted thereon, tapes carried by said rollers, delivery feed-rollers mounted on the carriage and operating to grasp and deliver the sheets fed thereto by the tapes, and a shiftable gear mounted on .one of said feed-rollers and arranged to be thrown at will into gear either with one of the tape-rollers or with means for impartingv to said feed-roller a rotary motion alternately in opposite directions, substantially as described.

4.
