IMPROVEMENT IN REGISTERS FOR MACHINERY. I

Specification forming part of Letters Patent No. 144,861, dated November i5, 1h73; application iiltd July 23, 1873.

To all whom it may concern:

Be it known that I, SHELDEN F. PAYNE, of Chicopee, I-Iampden county, State of Massa chusetts, have invented an Improved Counting-Machine, of which the following is a speciiication:

My invention consists of a combination of devices arranged in small space, by which a record of mechanical motions may be automatically kept, and by which a required number may be set olf, and upon the completion of the number an alarm may be sounded and the mechanism stopped.

In the drawings, Figure I is a plan view. Fig. II is an end view. Fig. III is a crosssec tion on line .r y, Fig. I, and Fig. IV, a detail view.

This machine, as illustrated in the drawings, is more particularly adapted for use in connection with a punching press, and for the purpose of indicating when a certain number of pieces shall have been punched out, and, as shown in Fig. I, it would be attached to the side of the frame of the press, and A would represent one end of the crank-shaft. From the end ot' shaft A the crank-arm B connects with' the sliding bar F, the ends of which are suitably guided at ff, so that the revolution of shaft A imparts a reciprocatiilg movement to the bar F. Hung on bar F at c is the spring-pawl C, whichengages, when not thrown out from the ratchet-wheel D, upon the end of the feed-screw E, sp thatjone 1'evolu tion ofthe shaft A and one reciprocating movement of bar F through the pawl C revolves the wheel D the distance represented by one of its ratchet-teeth. The feed-screw E is snpported from the plate V at both ends in the bearings b b, and parallel bars H H on each side of it assist in guiding and supporting the feed-nut XV. The nut lV is constructed in four parts, its sides h h being sleeved upon the rods H H, and the halves o o of the nut proper being held and moving upon the pins d d extending through the nut W, parallel to .each other, above and below the feed-screw E. The angle-lever G has one arm hinged to one section, o, and the other provided with a slot, in which a pin of the other section o plays, so that on opening or closing the nut, one section, in finding a bearing either against the side h I or screw E, affords a fulcrum to enable the lever to move the other. The nut WV when opened and the screw released can be slid upon the rods I-I H to any desired point. Upon one side ofthe nut is arranged the pointer m, and upon the other the spur n.

Now it is evident that the rotation of the ratchet D, by the reciprocating pawl C, will cause the nut WV to be moved upon the feedscrew E, and the pointer m to record such movement upon the scale s; and also that the proportion existing between the number of teeth upon the ratchet and the pitch of the feed-screw determines the degree of movement of the pointer, to which, of course, the scale must be proportioned. The number of ratchetteeth upon the wheel, and the pitch of the screw, may bear such relation to each other that a fine scale occupying small space will be suflicient to keep the account.

That it may be known when so many revo lutions of the shaft A, or reciprocations of bar F have been made, as has beemset off on the scale, I connect with the spring-striker of the bell I the hinged piece g, which presents an 'in clined surface, as seen at Fig. I, in the track of the spurn for the latter to come in contact with and push back until the movement of the nut shall carrythe spur past its shoulder when it is released and the alarm sounded, and the pointer m will stand at o on the scale. Should the revolution of shaft A be continued, a further movement of the feed-nut will bring its face against the pin K supported in an upright from the plate V, and push it so that its point will pass over the spring-pawl C to disen gage and hold it from the ratchet-wheel D, and consequently prevent the motion of the reciprocating bar from being communicated to the wheel. A spring, y, returns this pin to the position shown in Fig. I when pressure is removed frein it; and, that this pin may be projected at any time over the pawl to stop the feed, I hinge upon the plate V the lever X, and provide one end with a pull-handle, It, and bring the other against the head of the screw. This I find very convenient when an imperfect piece of work is punched out, which it is not desirable to count with the rest, as the handle It may be then pulled until one piece shall have been punched by the press without having been counted, to compensate lor the imperfect piece counted but thrown aside.

Now, having described my invention, what I claini is- 1. In combination with shaft H ivith its crankarni B, the sliding reciprocating bar F, for the purpose of diverting the rotation of the shaft A in either direction through pawl and ratchet C D to screiv E, substantially as shown and described.

2. In combination with feed-screw E and with rods H H, the feednut 7W having the sides 7i h, sections o o, supports d d, and operating-lever G, substantially as shown and described.

3. In combination With the feed-nut IV, the pointe;` m and spur ln, as shown and described.
