TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM WELOH, of Bridgeport, in the county of Fairficld, and State of Connecticut, have invented a new and improved Indicator for Punching Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 represents a froiit view of my improved indicator.

Figure 2 is avertical longitudinal section of the same, the plane of section being indicated by the line a 2;, fig. 1. v

- Figure 3 is a front view of the plates by which the hundreds and thousands are registered, the dial-plate being removed.

Similar letters of reference indicate like parts.

This invention relates .to a new device by which the number of strokes of punches, shears, milling machines, and all machines in which reciprocating motion is generated by rotary motion can be registered, said device being so arranged that the registering apparatus can be p ut'at rest, when it is not desired that the strokes should be counted, as, for instance, for lubricating, repairing, and testing purposes,

A represents the gate of a power-press or punching machine. On its face is a recess, in which the sliding box B, which forms the bearing for the eccentric shaft O, is fitted. By the revolution of the said shaft O the box I3 is moved laterally in the gate, and up and down with the same, the said gate sliding in a stationary standard, D, as usual. E is the cap, which is fitted to the gate by means of L-shaped knobs a a, in the manner described in an application for a patent which was made by me on or about the first day of April, 1867. On the inner face 0t this cap E is arranged a sliding bar, F, which has, at each of its ends, a pin, I), and which is slotted, as shownin fig. 3, and is secured by means of screws or pins 0 that pass through the said slots to a back plate, d, of the cap. The pins 6 b fit around the sides of the box l3, and as the latter moves sideways in the gate it pushes the bar F sidcways. Or is a spindle, which is firmly fixed to and which projects from the face of the plated, and around which three or more or less ratchet'wheels, II, I, and I, are fitted, so that the same will turn on the said spindle. The innermost ratchet-wheel II may, if desired, be mounted on the spindle, and the latter hung in the plate (Z, so as to turn, as shown. Outside, and in front of the ratchet-wheels, is a stationary dial-plate, 7:,wl1ich is divided into one hundred (more or less) equal spaces, which are marked with appropriate figures, as shown in fig. 1. Each of the ratchet-wheels is connected with a hand or pointer, by which the number of revolutions or moves made by them is indicated on the dial-plate. The hand 0 is fitted on the spindle and turns with the wheel II, the handf is fitted around the tubular projection of the wheel I, and the hand g is in a similar manner connected with the disk J. To the bar F is pivoted a spring, 71, which presses the lower end of a pointed rod or plate, 2', into the teeth of the wheel II, and, as the plate F movcs to and fro, this point carries one teeth of the wheel II with it, and thereby moves the hand 0 one on the dial-plate. The upper end of the rod z'is suspended from a pin, j, which is eccentric, and which can be turned so as to throw the lower end of the rod out of the wheel II, when the indicator will not be acted upon by the motion of the box 13. Between the wheels H and I, and between I and J, are interposed metal plates L and M respectively, which are both pivoted to the plated by means of ,a pin, Z, and which are provided with an eccentric slot around the spindle G, and which have at their free ends spring-pawls m and m, which fit respectively into the teeth of the disks behind which they are arranged. On the face. off the disk H is a pin, a, which fits into the eccentric slot in the plate L. This eccentric slot has two projecting portions, 0 andp, against which the pin 11 strikes as it turns with-thc disk II. When it strikes against the lower projection o it depresses the plate L, and moves the pawl minto a next tooth below. Whcn it strikes the upper projection 11 it raises the plate L, thereby pushing the pawl m up, and turning the disk I so far that its indicatorfwill move one on the dial. Thus each stroke of the gate is registered by the hand 0, each revolution of the plate lIby the hand f, and each revolution of the plate I by the hand g, as the disk J is moved by means of a pin, n, on I, and by the plate M and pawl m, in the same manner as I is moved by means of the pin 70 on H, and by the plate L and pawl m. Any number of such disks and hands can be arranged on any one machine, whereby, if desircd,an indefinite number of strokes can be registertd.

What I claim as new, and desire to secure by Letters Patent, is

1. Providing an indicator which registers the strokes of devices making regular reciprocating movements, and of reciprocating gates that are operated by ecceutrically moving boxes B, or their equivalents, substantially as set forth.

2. The slotted sliding-rod F, when provided with pins 6 b and with a spring, h, and when combined with the pawl z', ratchet-wheel H, and hand 0, and with the box 13, substantially as and for the purpose set forth.

3. The manner herein shown and described of throwing the indicating apparatus out of gear, by nieans of the eccentric pin j fitting through an eye on the rod 1', substantially as herein shown and described.

4. The arrangement of the pivoted plate L, having an eccentric slot, and fitting around the pin 12, and con nccted with the pawl m, for the purpose of indicating the revolution of the lower disk on the hand of the disk above, as set forth.
