TALBOT C. DEXTER, OF PEARL RIVER, ASSIGNOR TO THE DEXTER FOLDER COMPANY, OF YORK, N. Y.

PAPER-REGISTERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 550,950, dated. December 10, 1895.

Application filed October 26, 1894.

To aZZ whom it may concern.-

Be it known that I, TALBOT C. DEXTER, of Pearl River, in the county of Rockland, in the State of New York, have invented new and useful Improvements in Paper-Registering Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates more particularly to the electrically-controlled paper -registering machine shown in my prior application for patent, Serial No. 509,444, in which the gripper is caused to take hold of the paper solely by mechanical force and caused to release the paper at the proper time by electric magnetic energy transmitted mechanically to the gripper. To effect this operation of the gripper, I found it necessary to employ a lost motion in the mechanism which imparted reciprocating motion to the gripper in order to open the gripper for receiving the margin of the paper and subsequently close the gripper to take hold of the paper and draw it laterally. Said lost motion entails considerable Wear of the joint by which the gripper is connected to the pitman.

My present invention is designed to obviate this defect and to increase the efficiency of the registering-machine; and to that end the invention consists in the improved construction and combination of parts hereinafter fully described, and specifically set forth In the annexed drawings, Figure 1 is a plan view of my improved paper-registering machine applied to a paper-folding machine.

on line X X in Fig. 1, showing the registering mechanism in its two extreme operative positions. Fig i is a side view of the machine. Fig. 5 is an enlarged transverse section on line Y Y in Fig. 2. Fig. 6 is a vertical longitudinal section on line 0 O in Fig. 7, and

gage, which arrests the longitudinal movement of the paper preparatory to being registered and folded. All of said parts are of the usual well-known construction.

I do not limit my invention to its application to paper-folding machines, as it is equally useful on paper-feeding machines and other machines requiring the paper to be fed to them one sheet at a time and said sheet to be adjusted to proper alignment preparatory to being operated on.

To the top of the frame A is rigidly secured a horizontal guide 0, which is at right angles to the paper-supporting bars a a. Upon this guide rides the reciprocating slide D, from which extends rigidly the lower jaw J of the paper-gripper. Said jaw is immediately beneath the panel of the paper. The upper jaw J of said gripper is hinged to the slide D at the heel of the lower jaw, as shown at b, and is sustained normally in an open and raised position by any suitable means, preferably by a spring 0, connecting said jaw to an arm d,

which projects upward from the slide or heel of the lower jaw and has secured to its upper end the electromagnet 'm, which extends rearward from said arm. The upper jaw has rigidly affixed to it an arm d, extending upward from the pivoted end of the jaw andhaving secured to its upper end the armature 'm.

On'the slide D is carried an electric-circuit closer consisting,essentially,of two yieldingly-supported poles held normally in a cir- Quit-breaking position and in the path of the paper to be actuated to close the circuit by one of the poles coming in contact with the edge of the paper. This circuit-closerI prefer to form of two small levers ll, pivoted at or near the center of their lengths to ears ee on the under side of the slide D and projecting with their upper ends through slots in the jaws. The contact-point e onthe upper end of the lever Z is connected by a wire f to the magnet m, and wires f and f connect, respectively, the lever Z and magnet with the battery L.

From the slide D depends a hanger h, terminating with a horizontal eye or guide h, in which is supported one end of a push-bar g, which end abuts against the lower portion of the lever Z. Said bar is sustained yieldingly ation of turning it.

as hereinafter explained. are adj ustable longitudinally on the push-bar in a longitudinal direction and in its normal position by means of collars t' and t", attached to the bar 9 at opposite sides of the hanger, and an expansive springj, interposed between the rear collar 1" and hanger 72, which spring forces the bar rearward, which movement of the bar is arrested by the collar t coming in contact with the aforesaid hanger, as shown in Fig. 3 of the drawings. The lever l is made to rest by gravity against the end of the push-bar 9, so as to maintain it in contact therewith. The outer end of the push-bar passes through an eye 011 a bracket 7t, which is mounted on a guide '22 fixed to the frame A parallel with the bar 9. provided with an arm 7c, in which is j0urnaled a screw 0, parallel with the guide it and passing through a nut secured to or formed in the side of the frame A. The screw is shouldered on the arm 7c", soas to cause the bracket to move longitudinally with the screw. A hand-wheel o is attached to the outer end of the screw to facilitate the oper- To the push-bar is attached a third collar t' between the bracket 7; and collar 1" and arranged in such a position as to come in contact with the bracket '7; during the latter part of the outward or retrograde movement of the slide D. Said contact prevents the bar 9 from following the slide to the end of its said movement and thereby causing said bar to push the lever Z out of contact with the companion lever Z, All of said collars to permit the operation thereof to be regulated.

The slide D, which carries the gripper, receives its reciprocating motion from a rotary cam T by means of a lever 12, fulcrumed'on the frame A and having one end engaging thecam and the oppositeend'connected to the slide D by pitman P.

In order to allow the gripper to be adjusted in its position sons to operate on paper of different sizes, I make the pitman P adjustable in length by forming the same of two end sections, which are screw threaded, re-

spectively, right and left and coupled together by a turnbuckle or sleeve P, having corresponding right and left screw-threads in opposite ends. By turning said sleeve the two end sections of the pitman can be moved either from or toward each other to increase or diminish the length of the pitman,-as may be desired. The collars it 7 are to be adjusted correspondingly on the bar g.

The operation of the described registering maehine is as follows: The paper in process of being fed to the folding-machine is arrested in its movement by the end gage B. Then the slide D is pushed forward or toward the paper, and in this movement the gripper is in its open position to receive the margin of the paper between the jaws J Jand cause the edge of the paper to push the lever Z into contact with the lever Z, and thereby close Said bracket is the electric circuit. This energizes the mag net m, and by the attraction of the armature m the upper jaw J is caused to press down upon the paper, which is thus gripped between the jaws. As soon as this is eifected the slide D receives retrograde movement and causes the paper to be drawn along by the gripper until the collar 11 011 the pushbar g strikes the eye of the bracket 70, whereby the further movement of the push-bar is arrested. to move sufliciently rearward to cause the push-bar to tilt the lever l, and thereby break the circuit. This allows the spring 0 to lift the upper jaw J, and thereby release the paper to be carried to the foldingrollers R R. The gripper remains in its open position during the next forward movement to receive the nextshe'et of paper in the manner before described.

Having described my invention, what I claim i's- 1. An electrically controlled paper registering machine comprising 'a reciprocating gripper having its jaws held normally in an open position, an electro'ma'gnet causing by the attraction of its armature to close said jaws, a normally open electric circuit and a circuit closer in the path of the paper to be actuated thereby as set forth.
