AUTOMATIC STOP ATTACHMENT FOR PAPER-EMBOSSING MACHINES.

SPECIFICATION forming part of Letters Patent No. 633,701, dated September 26, 1899.

Application filed November 25, 1898 Serial N0. 697,330. (No model.)

To aZZ whom, it may concern:

Be it known that 1, JOHN ALEX. PRINCE, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented a new and useful Improvement in Automatic Stop Attachments for Paper-Embossing Machines, of which the following is a specification.

My invention relates to an improvement in automatic stop attachments for paper-enibossing machines in which the machine is automatically stopped should the paper cling too long to the impression-roller.

My improved stop attachment is operated by means of a normally stationary roller mounted in proximity to the face of the impression-roll, the distance between the roller and impression-roll being such that if the embossed paper should pass around the impression-roll far enough to pass between the two rollers the stop-attachment roller would be operated to stop the machine by the folding of the paper between the impression-roll and stop-attachment roller.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents an end View of an embossing-machine with my improved stop attachment applied thereto. Fig. 2 is a partial front View of the same. Fig. 3 is a vertical section through the machine from front to rearin the plane of the line 3 3 of Fig. 2. Fig. 4: is a view of the latch-bar and its adjacent parts, the latch-barbeing shown in full lines engaged with its catch and in dotted lines in the position which it assumes when raised by the tripping-arm. Fig. 5 is a view of the same parts, showing the position which they assume after the latch-bar has been released. Fig. 6 is a vertical cross-section in the plane of the line 6 6 of Fig. 5, and Fig. 7 is a detail View of the tripping-arm-operating cam.

My improved stop attachment, which is under the control of the embossed paper as it leaves the impression-roll, is herein shown and described in connection with my stop attachment for use in connection with the paper which is being fed into the machine,which latter stop attachment and mechanism form the subjectmatter of Letters Patent No. 615,900, granted to me on December 13, 1898,

for an improvement in automatic stop attachments for paper-embossing machines.

A A designate the side frames of the embossing-machine, between which are mounted an embossing-roll l3 and an impressionroll 0. These rolls are geared together by spur-gears b c exterior to the side frame A. The embossing-roll B is geared to and rotated by a drive-shaft D, suitably mounted in the machine,.which drive-shaft is provided with fast and loose pulleys (Z d. The drive-shaft D is rotated by a belt E, running to a source of power. (Not shown.)

A belt-shifter F is mounted to reciprocate upon suitable guide-rods ff, extended outwardly from the side frame A, which beltshifter is provided with a suitable loop f for engaging the driving-belt E.

A guideroller Gis mounted across the front of the machine in suitable vertically-adjustable bearings g, and a smaller guide-roller H is mounted between the side frames A A at a point to the rear and slightly below the guide-roller G.

A roll of paper I is wound upon a beam 2', which is mounted in supporting-brackets i on the side frames A A in front of the guideroller G. The paper is led over the guideroller G, under the guide-roller H, and between the embossing and impression rolls B and 0, from thence partially around the roll C, and from thence over a roller h, at which point it leaves the machine.

The roller J is mounted in bearings j on the side frames A A, thesaid roller being located directly above the roller G, the distance between the two rollers being just sufficient to permit paper of the required thickness to pass therethrough without engaging the roller J. Acam K is secured to the end of the shaft of the roller J exterior to the side frame A.

A tripping-arm L is hinged at Z to the side frame A, and at its free end the said arm is provided with a roller Z, arranged to engage the periphery of the cam K. This cam is provided with a slightly-depressed portion 70, within which the roller Z seats, so that the roller J will not be caused to rotate unintentionally-as, for instance, by the jar of the machine.

A rock-shaft M is mounted in bearings m upon the side frame A and is provided with upwardly-extended arms m m the arm m having a handle m at its free end. The arm m is connected with the belt-shifter F by a bar m so that the rocking movement of the shaft M will operate the belt shifter and cause it to shift the belt from one to the other of the fast and loose pulleys (Z (Z on the driveshaft. A retracting-spring N extends between the end plate f of the belt-shifter guide and the arm n for shifting the belt from the fast pulley to the loose pulley.

The belt-shifter F is held against the tension of the spring N, with the driving-belt in engagement with the fast pulley (Z, by means of a latch-bar O, hinged at 0 to the arm m of the rock-shaft M, which latch-bar is provided with a suitable notch 0, which is engaged by a catch 1?, secured to the front of the side frame A. The latch-bar O is provided with a lug 0 which rests in close proximity to the tripping-arm'L when the latch-bar is held in its locked position.

A roller Q is mounted in adjustable bearings g on the side frames A A. This roller is located at a point to the front of the impression-roll O and may be adjusted toward and away from the impression-roll until the space between it and the impression-roll is just sufiicient to permit the'impression-roll C to rotate without rotating the roller-Q. The roller Q is connected with the roller J by a belt q, whereby the rotary movement of the roller Qwill be communicated to the roller J.

The operation of my attachment is as follows: If the embossed paper being delivered from the machine from the impression-roll should cling to the said roll until it pass between the impression-roll and the roller Q, as shown in dotted lines on Fig. 3, the roller Q would be rotated, and through the belt q would rotate the roller J. This rotation of the roller J will cause its cam K to swing its tripping-arm L upwardly, and which when turned will raise the latch O and release it from its catch P. The retracting-spring N will then rock the shaft M outwardly, thereby causing the belt-shifterto shift the belt from the fast pulley onto the loose pulley, and thus permit the machine to stop.

By the use of this automatic stop attachment the paper which is being delivered from the embossing-machines does not have to be watched by an attendant, for the reason that the machine will stop immediately if the paper should not be delivered properly there-. from.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts'without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but

hat I claim is In a paper-embossing machine, embossing and impression rolls, means for operating the rolls, an operating-roller mounted in stationary bearings in proximity to the impressionroll at a point beyond where the embossed paper is normally delivered from the impression-roll, the said roller being adapted to be rotated by the passage of the paper between it and the impression-roll, and a stop mechanism under the control of the rotary movement of the said operating-roller, substan- JOHN ALEX. PRINCE.
