GEORG P. FENNER, OF NEV LONDON, CONNECTICUT.

SHEET-DELIVERY APPARATUS.

SPECIFICATION forming pari: of Letters Patent No. 324,245, dated August 11, 1885.

Application tiled December 18, 1884. (No model.)

To all whom, it may concern.' v l Be it known that I, GEORGE P. FENNER, a

l citizen of the United States, residing at New 'side upward and without being touched on such side by any part of the apparatus. This object I have accomplished,as hereinafter described and illustrated in the accompanying drawings, in which- Figure l is a side elevation of my apparatus, showing it applied to a printing-press. Fig. 2 is a plan or top view thereof. Figs. 3 and 4. are details, and will be referred to as this description progresses.

Similar letters indicate corresponding parts.

The letter A designates the press-frame,con structed to support the revolving impressioncylinder B and the type-bed C in proper relation to each other. D indicates a spur-wheel arranged on a shaft, D, Fig. l, to engage a horizontal row or series of studs, C', on a pendent portion of the bed, alternately above and below the plane of the studs, for imparting the proper motion to the bed, and B', Fig. 2, denotes a cog-wheel arranged on the shaft of the cylinder to gear with the driving-shaft for imparting the proper motion to the cylinder.

In a suitable cavity of the cylinder B are arranged the usual grippers, B3; for holding the sheet to be printed on the cylinder, those grippers being opened and closed by trip-pins B4, acting on cam B5, Fig. 2, of the grippershaft B". The cylinder B makes two revolutions during a complete traverse of the bed in both directions, and to adapt the gripper B3 to such motion of the cylinder the trip-pins B4 are alternately thrown out of action by means of a cam and cam-levers, the whole constituting a press of well-known construction.

To one of the longitudinal edges ofthe bed Cis secured a rack, F, which` meshes into a gear, G, mounted on a stud, a, projecting from the frame A. This gear G, to which reverse motions are imparted by the rack F, as the saine receives a reciprocating motion by the type-bed, carries a chain-wheel, b, over which a chain, b, passes for transmitting the reverse motions of gear G to the shaft h. This shaft turns in bearings in the vframe A, and on it are mounted chain-wheels c c,over which chains dd pass to pulleys e e. These chains d d serve to impart a reciprocating motion vto a sliding carriage, I, which is secured to them at fj'. In this carriage I are bearings for the shafts g g', which respectively carry tape-rolls H H', the relative distance between which remains unchangedas the carriage is carried back and forth on the guide-rods J .I by the chains d d. These guide-rods are rigidly secured to the frame A ofthe press, and on them areV fixed brackets K K, the upper ends of which serve as bearings for the shaft ,carrying the chainpulleys e e, while the lower serve as bearings for the shaft j, carrying the iixed tape-roll L. In the frame near the inner ends of the guiderods J .I are formed bearings for a shaft,`k, on which are mounted the tape-roll M and the pulley N. To this shaft a continuous motion in the direction of arrow 1, Figs. 1 and 3, is transmitted by means of a belt, l, which passes over pulley N, Fig. 2, and the cylinder B. The tapes m, for carrying the printed sheet from the cylinder, as they pass over the various tape-rolls H, H, L, and M,{see Figs. 1 and,3,) have a continuous motion in the direction of arrow 2, Figs. l, 2, and 3, independent of any motion of carriage I. Adj ustuble sheetguides O are placed between the tape-roll M and the cylinder B in such a manner that when the sheet leaves the cylinder the front edge is supported and guided onto the tapes m.

To raise the edge ofthe sheet from the cylinder after it has been printed and while the grippers B3 are open a series of sheet-litters, n, are mounted on a shaft, o, which has its bearings in the cylinder B, and one end of which is provided with alever, p. This lever carries at one end a link, q, provided with a friction-roll, r, which bears on a cam, s, mounted on the gripper-shaft BG. (See Fig. et.)

Vhile the grippers are closed, as in Fig. l, the sheet-litters n lie below the surface of the cylinder, but as the grippers are turned open and the cam s revolves the lever p is raised IOO against the action ol" the spring t, Fig. 1, thereby turning the shaft o and raising the sheet-litters n to the position shown in Fig. 3, and in dotted lines inv Fig. 4, thereby raising` the edge ofthe sheet from the cylinder and onto the sheet-guides O, thus insuring a positive delivery from the iimpression-cylinder onto the tapes m.

The operation of my apparatus is as follows: The sheet as it is fed from the table is grasped by the grippers Ba in the cylinder B and is carried over the type-bed C, where it is printed, and as the cylinder begins to make its second revolution the grippers are opened, thereby bringing the sheet-lifting device above described into play, and the sheet is carried over the sheet-guides O onto the moving tapes m, the position of which at this stage of the operation is shown in Fig. b. AsV the revolution of the cylinder cJntinucs and the typebed carrying the rack F begins its reverse motion the chains move in the direction of the arrows in Fig. 3, causing the carriage I to move in the direction of the arrow 3 until the type-bed has reached the position shown in Fig. l, where the carriageI will be in the position shown in said iigure.

' The cylinder is then in position to take a new sheet, and as the type-bed passes under the cylinder the rack secured to it will turn the gear G and chains b' and d d, as indicated by arrows Z, in Fig. 1, thereby moving the carriage I away from under the sheet, while the continuous forward motion ofthe tapes m causes it to run ofi' the carriage and against stops Q and drop onto the table P, thereby completing the operation and delivering the sheet without having touched its printed face.

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

l. The combination, substantially as hereinbefore described, 'with the impressioncylinder and the type-bed,of the tape-roll M,n1eans, substantially such as described,for imparting to this tape-roll a continuons revolving motion in one and the same direction, the tapecar riage I carried by guides,and mechanism,snb stantially such as described, for imparting to this tape-carriage a reciprocating motion in the line of travel of the tapes.

2. The combination, substantially as hereinbefore described,with the impression-cylinder and the type-bed, of the sheet-delivery tapes m, passing over the rolls M L, which revolve in fixed bearings, and over the rolls II H',which have their bearings in the tape-carriage I, the belt Z for imparting to the tape-roll M a continuous revolving motion in the same direction, and mechanism, substantially such as de scribed, for imparting to the tape-carriage a reciprocating motion.

3. The combination, substantially as hereinbefore described, withtheimpression-cylinder and the type-bed, of the sheet-delivery tapes m, passing over the rolls M L, which revolve in fixed bearings, and over the rolls H H', which have their bearings in the tapecarriage I, means, substantially such as described,for imparting to tape-roll M a continuous revolving motion, mechanism, substantially such as described, for imparting to the tapecarriage a reciprocating motion, the sheet-guides O, and the sheet-litters a.

4. rlhe combination, substantially as hereinbeiore described, with the impression-cylinder and the type-bed, of the tape-carriage I, the endless chains d,to which the tape-carriage is attached, the endless chain b', for imparting to chains d a reverse motion, the tape-rolls M and L, mounted in fixed bearings, and the belt Z for imparting a continuous revolving motion to the roll M.

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

GEORGE I. FENNER. [Ls] Witnesses:
