PER-FORATING-MACHINE.

Application filed September 13, 1913.

To all whom it may concern Be it known that I, PHILIP J. MEAHL, a citizen of the United States, and resident of Summit, in the county of Union and State of New Jersey, have invented certa1n new and useful Improvements in Perforating-Machines, of which the followmg 1s a specification.

This invention relates to improvements 1n perforating machines and particularly to that class of perforating machines wh1ch are used for making perforated music sheets to be used in connection with automatically playing musical instruments, in which perforated music sheets the slots or perforations are arranged in a series of rows eX- tending lengthwise of the sheet and spaced uniformly transversely to the sheet.

The object of my invention is to provide a new and improved perforating machine for the above-mentioned purposes, which is simple in construction, effective and reliable in action and by means of which perforations of different shapes, size, style or character can be produced successively or alternately in the same longitudinal row of slots or perforations all in a single passage of the blank sheet to be perforated through the machine.

In the accompanying drawings in which like letters of reference indicate like parts in all the figures: Figure l is a plan view of my perforating machine, parts being broken away and some omitted. Fig. 2 is a vertical longitudinal sectional view on the line aa, parts being broken away.

The machine is constructed with a main frame 1 011 which all the several parts are mounted. At the center of the main frame two standards 2 are provided, one on each side, in which is mounted the main drive shaft 3 carrying a fly wheel 4; and any suitable means for rotating the shaft from a source of power. On this shaft is fixed a cam disk 5 having a groove into which a pin 6 passes, which extends laterally from the top of a vertically reciprocating punch operating head 7 suitably guided in the side frames of the machine. Beneath the head 7 two transverse punch guides 8 are secured in the side frames, directly above two dieholding blocks 9 on the top of each of which a die plate 10 is secured. In the punch guide 8 a series of punches 11 are guided to move vertically, each punch being provided at its upper end with a button 12 which Specification of Letters Patent.

rests in a recess 13 in the punch operating head 7, so that as the head moves upward the punches are all raised. Above each button 12 a horizontal punch controlling slide 1 1- is mounted on edge so that it can be shifted across the head 7 horizontally and each slide is provided in its bottom edge with a notch or recess 15 into which the button 12 of the punch directly below it can pass when said notch or recess is in alinement with the punch. In a bracket 16 at each end of the main frame 1, a transverse shaft 17 is mounted on which is secured a perforated-master sheet drum 18 of conventional construction, which drum is provided at its end with sprocket teeth 19 which can pass in slots out along the edge of the master sheet, in the well known manner. This drum is driven by suitable gearing to be described hereinafter, from the main shaft 3, so that a pre-determined relation is established between the speed of rotation of the main shaft 3 and the drum 18 and for each rotation of the main shaft, the master sheet drum is rotatively shifted a certain distance. A series of horizontal selector pins 22 are guided at their free ends by a guide plate 23 adjacent to and parallel with the drum 18 and the opposite end of each of these selector pins is pivotally connected with the upper end of a curved substantially L-shaped lifting lever 24% pivoted at 125 to a bar 28 having a series of vertical slots 27 in which said lifting levers 24 are severally located. Each selector pin is connected above its pivot with one end of a spring 28, the opposite end of which is secured to a bracket 29 on the bar 26, which springs serve to pull on the upper ends of the lifting levers, thereby gently pressing the free ends of the selector pins against the master sheet passing over the drum 18, the lower ends of which lifting levers each terminate in a head 30 resting within a notch 31 of a thrust block 32 of which one is provided for each lifting lever, said thrust blocks being suitably guided in slots in the bar 26'to move up and down vertically under the action of the lifting levers 24:. Whenever a hole appears in the master sheet opposite the row of guide holes in the guide plate 23 the corresponding selector pin is forced to the right into said hole in the masier sheet under the action of a spring 28 and thereby the corresponding thrust block 32 is raised as indicated in dotted lines.

A carriage 33, extending transversely across the machine frame is guided at its ends in a horizontal guide 34 so as to reciprocate horizontally and in said carriage one 5 selector rod 35 is mounted for each slide 14 and corresponding lifting lever 24, one end of said selector rod being pivotedly connected with the corresponding slide 14 and the opposite end being connected with a U- shaped piece 36 mounted slidably in the carriage in such manner that the ends 37 of the long shanks of the several pieces 36 project beyond the right hand side of the carriage and into the paths of the several thrust blocks 32 whereas the shorter shanks of the U-shaped piece are each connected with one end of a spring 38, the opposite end of which is attached to the carriage, which springs thus serve for keeping the ends 37 of the U-shaped piece projected beyond the right hand side of the carriage and above the thrust blocks 32. The carriage 33 is provided with a laterally proj ecting pin 39 which is engaged by the lower forked end of a lever 40 pivoted at 4:1 and connected by a link 12 with a plate 43 having a longitudinal slot 44 through which the main shaft 3 passes. This plate carries a pin 45 which projects into a cam groove 46 of a cam disk 47 secured on the main shaft so that as the main shaft is rotated the lever 40 is rocked to and fro and correspondingly reciprocates the carriage 33 toward and from the thrust blocks 32.

The machiueryjust described is at the right hand end of the main frame 1 and identically the same machinery is found at the left hand end, but merely reversed so that each set of dies has its control slides, sliding carriage and selector pins and set of thrust blocks connected with the selector pins. The paper sheets d8 to be perforated are passed over the die plate 10 and this paper is shifted by a paper feeding device 49 of any well known construction. Adjacent to the outer edges and upper end parts of each group of lifting levers 24, at each end of the machine, I provide a bar 50 which can swing toward and from the upper parts of the lifting levers and serves as a restoring bar for bringing the lifting levers 24 and selector pins 22 connected therewith into normal position, once for each rotation of the main shaft. This bar 50 is connected by arms 51 at its end with a rock shaft 52 extending transversely across the machine, which rock shaft is operated by a bar 53 from a cam 54: of any suitable construction on the main shaft A shaft 55 is driven by suitable gearing of any suitable kind from the main shaft 3 and I prefer to use for this purpose the Geneva star wheel so well known in machines of this kind, that it is not necessary to illustrate or describe it. The shaft 55 at one end carries a bevel cog the opposite end the shaft 55 carries a bevel cog wheel engaging two diametrically op posite pinions 61, each on a shaft 62 parallel with the sides of the machine, which shafts 62 each by means of a worm 63 drives one of the master sheet drum shafts 17.

represents a table which supports the paper passing over the die plates.

71 represents the master sheets.

The operation is as follows:The master sheet must be so arranged that one master sheet controls the punches of one row of punches and the other master sheet controls the punches of the other row and the master sheets must be so arranged and spaced. that the punches of each row of punches will be operated at the proper time. For exau'iple, if the right hand row of punches makes large holes, the left hand row of punches should make small holes, or holes of another shape. If in one of the longitudinal lines of perforations in the paper sheet there are to be three successive holes made by large punches and the last one of these is to be followed by nine successive individual punchings of small holes and the paper moves from right to left, the master sheets are so arranged that the three successive large punchings are punched by one of the punches of the right hand group, the cone spending punch of the left hand group remains idle until finally the three holes made by a punch in the right hand group have passed beyond the left hand group of punches whereupon the correspondingpunch in the left hand group is operated the required number of times under control of the corresponding master sheet. lVhenever a. hole in the master sheet comes in line with a corresponding hole in the plate 23 the corresponding lifting lever 24 raises its thrust block 32. The machine is so timed that the 11 passing of the selector pins into the master sheet and the lifting of the thrust; blocks can only take place when the right hand carriage 33 has been moved to the left so that the projecting ends 37 of the U-shaped piece 36 are out of the way of the rising thrust block and when then the said right hand carriage moves to the right the ends 37 corresponding to the raised thrust blocks will strike against the raised thrust blocks, whereby the ends 37 and the corresponding U-shaped parts 36, rods 35 and slides 14: are all pushed to the left so that the recesses 13 in the corresponding slides 14 are no longer over the punch buttons and consequently the corresponding punches are depressed when the punch head descends. For each rotation of the main shaft the paper is fed forward a predetermined distance, the punch head being raised. The carriages 33 are moved toward the center of the machine and at the same time the restoring bars 50 are swung from the lifting levers to permit some of the selector pins to pass through the holes in the master sheet whereby the corresponding thrust blocks are raised. Then the carriages 33 are moved toward the thrust blocks and the ends 37 encounter the front edges of the raised thrust blocks whereby the corresponding slides 14 are pushed toward the center of the machine and solid portions of the slides are above the corresponding punch buttons and then the punch head descends and forces those punches over which there are solid portions of the slides 14 through the paper. The punch head rises, the carriages 33 are moved toward the center of the machine again and the restoring bars 50 are swung toward the center of the machine thereby withdrawing the selector pins that have passed into the holes in the master sheet and bringing all the thrust blocks into normal position and so on for each rotation of the shaft.

As has been pointed out, the corresponding punches in the two groups are in line so that one punch of each group can make a perforation in one and the same line or row of longitudinal rows of punchings in the sheet. The times at which the punches are depressed are controlled entirely by the arrangement of the slots in the master sheets and from the master sheet through the selector pins, lifting levers, thrust blocks, reciprocating carriages and the slides 14:, the selection and operation of the punches are thus controlled.

The master sheet drums 18 are provided with rows of holes as indicated on the right hand drum in Fig. 1 but the balance of these holes have been omitted to avoid confusion.
