APPARATUS FOR TRANSFERRING PAPER FROM FEEDING-MACHINES T0 PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 557,761, dated April 7, 1896.

Application filed February 2,1893. Renewed May 29, 1895. Serial No. 551,227. (No model.)

T0 (0% whom it may concern:

Be it known that I, THOMAS A. BRIGGS, of Arlington, in the county of Middlesex, in the State of Massachusetts, have invented new and useful Improvements in Apparatus for Transferring Paper from a Feeding-Machine to a Printing-Press, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The purpose of this invention is to provide simple and efficient means for transferring paper from a feeding-machine to the feed-table of a printing-press situated remote from said machine; and to that end the invention consists, essentially, in the combination,with said machine and press,of a fly,interposed between the same, and grippers moving lengthwise of the fly and transferring the paper from the feeding-machine onto the fly and the invention also consists in certain novel features of the details of the paper-transferring devices, and means for actuating the same, as hereinafter fully described, and specifically set forth in the claims.

In the accompanying drawings, Figure l is a side elevation of a paper-transferring apparatus embodying my invention. Fig. 2 is a plan view of the same. Fig. 3 is a vertical transverse section on line a: so in Fig. 2. Fig. at is an enlarged detached side view of the cam-disk which imparts motion to the fly and grippers in moving lengthwise of the fly. Fig. 5 is a detached side view of mechanism which transmits motion from the aforesaid cam-disk to the rock-arm, by means of which the grippers are moved lengthwise of the fly. Fig. 6 is an enlarged front view of one of the grippers. Fig. 7 is a vertical transverse section of the same. Fig. Sis a side view of one of said grippers, showing its position in relation to the fly in carrying the paper over the same. Fig. 9 is an enlarged side view of the device for cushioning the fly at the end of its stroke, and Fig. 10 is a plan view of the same.

Similar letters of reference indicate corresponding parts.

A denotes a paper-feeding machine, which feeds the sheets of paper singly from a pile supported on a table A. The mechanism for feeding said paper may be of any suitable and well-known construction, and for exem pliiication I have merely indicated by dotted lines in Fig. 9 of the drawings one of the feeding-fingers of the machine shown and de- 5 5 scribed in my United States Letters Patent No. 4803M, dated August 9, 1892.

B represents the impression-cylinder of a printing-press, and B the usual feed-table,

upon which the paper is placed preparatory to passing the same to the printing-press. The paper-feeding machine is arranged re mote from said feed-table, and in order to economize in room and render the combined feeding-machine, printing-press, and papertransferring devices as compact as possible I place the feeding-machine A over the end of the printing-press, as shown in Fig. 1 of the drawings.

From the printing-press frame, adjacent to 7 a theimpression-cylinder B, to the delivery end of the feedingmachine A, I extend two parallel rectilineal guides O O, firmly secured thereto. Upon these guides, adjacent to the impression-cylinder, I mount the pedestals D 7 5 D, to the bases of which I pivot the shaft F of the fly F, which is adapted to swing with its free end back and forth to and from the paper-feeding machine A and feed-table B.

This fly receives its motion by the following mechanism: To the end of the fly-shaft F is fastened a gear-wheel G, with which meshes a segmental gear G, pivoted to the upper end of the pedestal D, which latter gear receives an oscillatory motion from arevolving cam longitudinal slot 1, receiving through it the hub of the camdisk I-I, so as to support said end of the pitman. On the end of the pitman is pivoted a roller I, which travels in the groove H of the cam-disk.

In order to properly time the movement of the fly so as to swing with desired speed back and forth between the feeding-machine and Said slot allows the pit- 9o printing-press and hold it dormant a sufficient length of time to allow the paper to be transferred onto it from the feeding-machine A, a portion of the cam-groove II is formed concentric to the axis of the disk, and the remainder of said groove being in two short curves extending from the ends of the concentric portion and meeting in proximity to the opposite side of the axis of the disk, as shown in Fig. l of the drawings.

Upon the guides G C, I mount the slides L L, on which are supported the ends of the shaft a, which is parallel with the axis of the fly, and to this shaft I fasten the gripperarms I), as shown in Figs. 6 and 7 of the drawings. This arm is provided with a verticallymovable stem 1), to the upper end of which is secured the gripper finger or jaw b. To the lower portion of said stem is attached the foot (I, and between the top of the foot and a bearing in the upper portion of the arm I) is a spiral spring (1, which depresses the stem and thereby holds the gripper normally closed.

For opening and closing the grippers at opposite ends of the strokes of the fly I pivot to the slides L L another shaft a, which passes through eyes in horizontal projections on the bases of the gripper-arms b, and thus sustains said arms in their erect positions. To the shaft to are fastened the cams d, which bear on the under side of the feet (I.

To one end of the shaft to is firmly secured the tripping-finger a", which at the end of each stroke of the fly comes in contact with one of the two stops 0 0, attached to opposite ends of the guide C. The contact with the stop 0, near the heel of the fly, turns the shaft (1., so as to cause the cams cl to pry up the feet (Z of the grippers Z)" and thus release the sheet to allow it to be taken by the usual grippers of the impression-cylinder B. In this operation of opening the grippers b the cams are turned past a vertical position and become partially locked under the feet (1 to maintain the grippers in their open position during the reverse movement of the slides L L, by which the said grippers are caused to approach the paper-feeding ma chine. At the end of this movement the contact of the tripping-finger a with the stop 0 turns back the shaft a, and thus causes the cams to release the grippers to take hold of the advance edge of the sheet delivered thereto by the feeding-machine.

The slides L L receive longitudinal motion on the guides O C by means of the rock-arm N, which is pivoted to the frame of the feeding-machine A and connected at one end to the slide L by a pitman O. The opposite end of said rock-arm is pivoted to the free end of a lever P, which is pivoted to the aforesaid frame and is provided with a longitudinal groove, in which travels a roller f, pivoted to the back of the cam-disk H, the rotation of which imparts an oscillatory motion to the lever P.

In order to enable the rock-arm N to move the slide L the entire length of the guide 0, I apply to said rock-arm the mechanism shown in my United States Letters Patent No. 480,4l9, dated August 9, 1892, said mechanism consisting, essentially, of a shaft extending lengthwise of the rock-arm and journaled thereon. A pinion on the inner end of said shaft, meshing with a stationary gear on the frame of the machine, imparts rotary motion to the shaft during the oscillation of the rockarm. A miter-pinion on the outer end of said shaft meshes with a similar pinion on a short shaft pivoted crosswise to the free end of the rock arm, and an arm fixed at one end to said short shaft has connected to its opposite end the pitman O.

R represents a cushion which is sustained in a position to receive the impact of the free end of the fly at the end of its stroke toward the feeding-machine. This cushionI form of a rubber tube g, a portion of the circumference of which is inserted into a tubular bar h, which is provided with a longitudinal slot, through which a portion of the circumference of the tube protrudes, as shown in Figs. 9 and 10 of the drawings.

The rubber tube is secured in the bar by means of a plug 7L driven into the inclosed portion of the tube. For sustaining said cushion in its position I prefer to employ a horizontal shaft 1', fastened to the frame of the feeding-machine A and having secured to it the arm j, the free end of which is formed with the tubular and longitudinally-slotted bar or cross-head 7L, within which the rubber tube 9 is secured in the manner aforesaid.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
