SHEET-DELIVERING APPARATUS FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No.311A32, dated January 27, 1885.

Application filed July 7, 1982.

To all whom it may concern.-

Be it known that I, BER'rHoLD HUBER, of Taunton, in the county of Bristol and State of Massachusetts, have invented a certain new and useful Improvement in Sheet-Delivery Apparatus for Printing-Presses, of which the following is a specification.

. My invention is applicable to cylinder printing-presses, and relates to the arrangement of the fly for taking the sheets from the tapes and depositing them upon the fly-board.

The invention consists in the con'ibination. with a fly having a horizontal shaft, which is i'ulcrumed at one side of the press or near one end of the shaft, so that it may be swung in a horizontal plane from a position crosswise of the press toward a position lengthwise of the press, of devices for giving such swinging movement of the fly-shaft and at the same time turning the shaft so as to reverse the fly-fingers and deposit the sheet.

The invention also consists in novel details of construction and combinations of parts in the mechanism for imparting the before-described double movement to the fly-shaft.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of a part of a press embodying my improvement. Fig. 2 represents a plan thereof, the side frames only beingin horizontal section. Fig. 3 represents an end elevation, and Fig. trepresents a detail view on a larger scale of one of the receiving-wheels and tape wheels or rollers.

Similar letters of reference designate corresponding parts in all the figures.

A designates the foundation-plate of the press, and A designates the side frames supported thereon.

B designates the impression-cylinder mounted in hearings in the side frames, A. The cylinder is provided with ordinary grippers, a, for taking the sheets from the feed-board O, the grippers being operated in any ordinary way. Below the feed-board is arranged a shaft, D, which may be operated by a handcrank, D, or other suitable means, and the shaft D carries a spur-wheel, D which engages with a wheel, B, of double its size upon the cylinder'shaft, and thereby imparts motion to the cylinder.

Upon the shaft D are a number of receiving.-

(N'o model.)

wheels, D and through these wheels extends a gripper-shaft, I), provided with a gripper, c, for each wheel, which is received in a recess, c, in the side of the wheel, as shown in Fig. 4. The grippers c are secured directly ,upon and are supported by the gripper-shaft in g-wheels D Around the small rollers or wheels e are passed tapes or bandsf,t11e upper sides of which are tangential to the receiving-wheels D and these tapes also pass around larger rollers or wheels 9 upon a shaft, as best shown in Figs. 1 and 2. The shaft 9 is rotated positively-as here shown, from the shaft D-by means of a belt, 9 passing around a pulley, upon the shaft D, and a pulley, g", on the shaft 9. The relative sizes of the pulleys g 9* and the rollers or wheels 6 g should be so proportioned that the tapes will travel at ex- 4 act] y the same speed as the peripherical velocity of the receiving-wheels D so that the freshly-printed sheet will not be smutted by the tapes or hands, as will be the case if said tapes do not travel at the same speed as the sheet is delivered from the wheels D E designates the horizontal fly-shaft, and h the fly-fingers.

F designates a vertical shaft at the side of the press and opposite the end of the fly shaft. The shaft F is madein two parts, as shown in dotted lines in Fig. 3, and these two parts are connected by a cross-head, F. The fly-shaft E passes horizontally through this cross-head and between the ends of the two parts of the shaft F, and thus the two shafts are connected together, so that the shaft F forms a fulcrum on which the shaft E turns.

G designates the fly-board, which is not placed directly in front of the press, but at one side and in advance thereof. The shaft F is adapted to turn in bearings i, and by so turning it the fly-shaft E is swung outward in an arc-shaped path, and is brought to the position shown in the dotted lines in Fig. 2.

Upon the shaft E is a bevel-wheel, j, or a segment of a wheel, and this engages with a stationary gear-segment,j, secured on the bed A. Consequently it will be understood that as the shaft E is swung bodily outward it is also turned by the gear-segment j turning on the stationary segment j, and reverses the fly to deposit the printed sheet on the fly-board G. By a reverse movement of the shaft F the fly-shaft is swung back into its former'posi-' tion, and is turned so as to bring the fingers into posit-ion to receive the sheet.

Any suitable mechanism may be employed to give the shaft F the desired rotation alternately in opposite directions. In this exam- 1e of my invention I provide a cam, H, upon the shaft of the cylinder B, and a horizontallymoving bar, I, having a roller, is, at one end entering the groove in the cam, and a rack, l, at the other end engaging with a segment-gear, m, on the shaft F. The bar I is slotted or bi,-

fu rcated to receive the cylinder-shaft through it, and asthe bar is reciprocated bythe cam H the shaft F will be turned alternately in reverse directions.

In the operation ofmy press the sheet is taken by the grippers of the impression-cylinder and is carried downward to receive the impression from the form on the bed. When the head of the sheet reaches the receivingwheels D their grippers, which have previously been opened, are closed on the head of the sheet, and by them the sheet is transferred onto the receiving-wheels. As the head of the sheet reaches the tapes the grippers of the wheels D are opened and the sheet moves downward onto the fly, and when nearly the whole sheet is on the fly the fly-shaft is swung outward and turned to deposit the sheet onto the fly-board G.

What I claim as my invention, and desire to secure by Letters Patent, isv

' 1. In a printing-press, the combination,with a fly having a shaft fulcrumed at one side of the press, of devices,substantial1y as described, for imparting a swinging motion to said flyshaft upon its fulcrum, and for instantaneously rotating it to reverse the fly and deposit the sheet, substantially as specified.

2. In a printing-press, the combination,with

a fly-shaft and an upright shaft to which the fly-shaft is connected, so that the upright shaft forms a fulcrum for the fly-shaft, of devices, substantially such as described, for imparting a rotary motion alternately in opposite directions to the upright shaft, a gear upon the flyshaft, and a stationary gear engaging therewith and servingto turn the fly-sh aft, substantially as specified.

3. The combination of the fly'shaft E, the

upright shaft F, the gear j, the stationary gear j, the cam H, the rack-bar I, and the gear m on the shaftF, substantially as specified.

BERTHOLD HUBER.
