To all whom it may concern:

Be it known that 1, JAMES G. .Hnnnrn, a citizen of the' United States of America, and a resident of Canton, county of St. Lawrence, State of New York, have invented a certain new and useful Improvement in EX- tension-Deliveries for Printing-Presses, of which the following is a specification.

The present invention relates to improvements in extension deliveries for printing presses and the like, where printed sheets are delivered by the press one at a time.

The object of this invention is to provide mechanism that can be attached to printing presses and the like where there is limited.

floor space between the printing press and the wall of the press room, or other obstruction which limits the passageway in front of the press where stock has to be moved.

Also it is desired to provide mechanism that will receive the sheets one at a time as they are printed and delivered by the press, and to carry forward these printed sheets one at a time and pass them through a jogging mechanism, and deliver them from it one at a time accurately piled upon a receiving table, with means to lower it in-- termittently so as to keep the top of the stack of sheets at a predetermined elevation. Then when it is desired to do so the receiving table may be elevated, carrying all of the parts mounted above it and the stack of sheets upon it, to an elevation above the working elevation, thus forming a passageway below the receiving table, and between the ink fountain of the press and the frame supports. a

The following are some of the new features in this invention:

(a) A frame work attached to the printing press supporting ways upon which a sheet carrying mechanism moves to and fro with suitable means to move the sheet from the press cylinder to the aforesaid sheet carr1er..

(b) A jogger frame containing suitable side joggers with means to move them to and fro, said frame attached rigidly to the aforesaid sheet carrier ways.

(0) A main shaft upon which are mounted .cable sheaves with cables suitably attached to said sheaves, suitable gearing to rotate said shaft, means to rotate said gears,

. sills attached to said cables adapted to carry a sheet receiving platform.

((Z) A power operated pawl and ratchet adapted to intermittently rotate said cable shaft.

The accompanying illustrations show the invention mounted upon aprinting press, although it may be used in connection with other kinds of machines delivering sheets singlyr Similar numbers refer to similar parts, throughout the drawings.

Referring to the various figures in detail, they are-as follows,

Figure l, is a side elevation showing the front end of a printing press with the extension delivery frame attached to it, which consists of uprights-attached rigidly to the frame of the printing press, side pieces and cross girts attached together and supported by legs. The-delivery is in ,working position.

In this frame workare ways resting upon suitable supports, a carriage moves to and fro upon these ways, suitable series of tapes driven by the press and adapted to convey a sheet from the press cylinder to the carriage with means to deposit it upon a movable elevator.

Upon the frame is mounted an electric motor, and in belted connection with a train of gears attached to a main shaft passing across the frame work, and having sheaves mounted upon it. Cables are wound upon said sheaves with sills attached to the loose ends which support the elevator platform upon which the sheets are deposited.

Fig. 2, is a longitudinal sectional view showing the elevator platform supporting a stack of sheets in a position above its working position so as to form a passage way below.

' Fig. 3, is a plan view showing the top of the frame, the shaft carrying the sheaves with the cables. Also the ways upon which the carriage rests, and the jogger frame between-the ways. Also a plan view of the motor and gearing.

Description of parts in detail. A is the'front end of a printing press, and

B is the ink fountain. 1 is a side standard of the extension delivery frame, 2 is a side piece rigidly attached to the standard and supported by 3, which is a leg. 4 is a way supported at one end on the bracket 5, the other end resting upon arm 6. 7 is a socket in the arm and receives the guide pin 8. 9 is a sleeve on the way and slides upon the leg 3. 10 is an arm mounted upon a power oscillated shaft of the press. 11 is a sheet carriage mounted upon the way 4, and is moved to and fro by the connecting link 12 which is pivotally attached to the carriage and the arm 10. 13 is an electric motor mounted upon the frame of the delivery and through the belt 51, pulley 14, and a train of gearing by which the shaft 15 is rotated. 16 is a sheave rigid upon the shaft 15, and carries the cables 17, that are attached to the sills 18, upon which rests the platform 19, on which is piled the stack of sheets, 20; 21 is a power oscillated shaft in the press frame upon which is mounted the sleeve 22, and to it is attached the strap 23. Attached to the strap is the adjusting screw 24, which passes through the arm 25, which is pivoted to the frame 1. 26 is a rocking arm pivotally mounted upon the shaft 27, and is rocked by the link 28. 29 is a ratchet upon the shaft 27 and is rotated by a pawl on the rock arm 26.

When it is desired to lower the elevator intermittently the pawl and ratchet is made operative and the electric motor is dormant, but when it is desired to move the elevator up or down at a continuous speed the pawl is thrown out of connection with the ratchet and the electric motor is made operative.

30 is a power rotated shaft in the printing press, 32 isa roll j ournaled in the press, and 31 is a set of tapes passing around 30 and 32. 34 is a roll j ournaled in a frame pivoted on roll 32. 33 are tapes passing around rolls 32 and 34. 35 is a support to the frame which carries the roll 34. 40 is a roll journaled in the press and is rotated by the pair of gears 36 and 37, which are rigid upon.

the rolls. 39 is a set of tapes passing around the rolls 38 and 40. 41 is a set of tapes passing around the roll 40 and an idler journaled in the press.

The purpose of these various sets of tapes is to carry the printed sheet from the cylinder to the sheet carriage.

44 is a part of the arm 25, 45 is a pull spring to move the arm 25. 47 is an arm on the shaft 52, which operates the joggers. 46 is a link between 44 and 47 48 is the main jogger frame and is attached to the ways 4 by the hangers 49.

Fig. 2 is a longitudinal sectional view showing the elevator at its highest position, with the ways and jogger frame elevated above it and the stack of sheets 20 supported on the elevator platform. By raising all of naeaaoe the parts above referred to it creates a passageway below the elevator platform and between the ink fountain and the legs of the delivery, through which truck loads of stoc may be moved.

Fig. 2 shows the link 46 detached from the arm 47. Also it shows the tape frame in which the roller 38 is journaled in an elevated position so as to admit the fingers of the carriage frame 11 to be elevated without contacting the roll. 42 is a shaft journaled in the main frame. 43 is a hand crank on shaft 42. 50 is a cable attached to the shaft 42 and the tape frame in which is journaled the roll 38.

Fig. 3 is a plan view showing the side pieces 2 and a cross girt 53, the jogger frame 48, and the main shaft 15, which is journaled in bearings on the frame. Power is transmitted from the motor 13 to the shaft 15 5 through a belt and a train of gears.

Fig. 4 is a cross sectional view of the jogge'r frame and the parts which operate the side joggers. A detailed description of the jogger frame and its working parts are fully set forth in my patent application No. 150,922, filed Feb. 26, 1917, for traying elevator, to which reference is made for a more complete description of the jogger frame and the working parts.

Manner of operation.

While the press is being gotten ready and the ink fountain being filled and adjusted, the elevator platform 19, carrying the jogger frame 48, and the ways 4, is raised to its highest position as shown in Fig. 2. This is done by making the pawl and ratchet on shaft 27 inoperative, soas to allow the electric motor to, through the belt 51 and the train of gearing, rotate the shaft 15 and so wind the cables 17 on the sheaves 16. When this is done a passageway is made below the elevator platform and between the ink fountain and the legs 3, which will admit of the moving of truck loads of stock past the press. This feature is desirable where printing presses are located near the side wall of the room or other obstruction which will not admit of trucks passing between the legs and the wall.

When the press has been made ready for printing the elevator is lowered to the position as shown in Fig. 1. Then the pawl and ratchet are made operative and the electric motor inoperative.

The sheets are carried from the cylinder between the sets of tapes and delivered on to any form or well known sheet carrying device that will carry the sheet forward and deposit it on the elevator platform. Such sheet carrying device may be moved to and fro by any suitable means on the printing press. Any suitable means to intermittently un- Wind the cables on the sheaves may be emstack of sheets will pass.

loyed onlythat it may be so adjusted to ower the stack of sheets the thickness of a sheet at each operation.

In the drawings I have shown the rockm 5 arm 25 connected to a power oscillated shat? the ratchet 29 is rotated.

The jogger frame 48 is hung below the ways and made rigid to the ways by the hangers 49 and by being made rigid it keeps the ways in position when they are raised above their working position.

Then a stack of sheets is to be raised above the working position as shown in Fig. 2, the joggers are manually set at their open position, so forming a throat through WhlCh the This will admit of the platform which is carried uponthe sills 18, contacting the jogger frame and so lift it and the ways.

This combination of parts and their operation will admit of a stack of sheets being left on the platform and raised so as toform a passageway below and then being returned to the working position and thus obviate the necessity .of removing the stack of sheets out of the delivery when stock 1s being moved past the press.

Having thus described my 1nvent1on,what I claim is,

1. In an extension delivery the combination of a frame, ways mounted in said frame adapted to be raised and lowered, a oweroperated member mounted upon sa1 ways adapted to arry and deliver a sheet, a power-operated receiving platform adapted to raise and lower said ways out of their noral position.

2. In an extension delivery the combination'of a frame,ways mounted in said frame adapted to be raised and lowered, a receiving frame mounted below said ways adapted to guide a sheet, a receiving platform mounted below said receiving frame adapted to receive said sheet, means to raise and lower said receiving-table,which platform by contacting said receiving frame will move said ways out of their normal position.

3. In an extension delivery the combination of a frame, ways mounted in said frame adapted to be raised and lowered, members adapted to guide said ways to position, a power-operated member mounted upon said ways adapted to receive and deliver a sheet, a receiving frame attached to said ways adapted to guide a sheet, a receiving platform mounted below said frame and adapted to receive said sheet, means to raise and lower said platform, which platform by contacting said receiving frame will move said Ways out of their normal position.

4:. In an extension deliverythe combination of a frame, ways supported upon guides in said frame, said ways adapted to be raised and lowered, a power-operated sheet-carrying member mounted upon said ways and adapted to receive and deliver a sheet, a frame attached to said ways adapted to guide a sheet, a receiving platform located below said frame adapted to receive said sheet, power-operated members mounted below said receiving platform adapted to raise and lower said platform, which platform by contacting said receiving frame will move said ways out of their normal position.
