MACHINE FOR PERi-ORATING PAPER.

SPECIFICATION forming part of Letters Patent No. 593,694, dated November 16, 1897.

Application filed January 23, 1896- Serial No. 576,534. (No model.)

To all. whom it mayconcern:

Be it known that we, HAROLD W; SHON- NARI) and GEORGE HOWLETT DAVIS, of New York, in the county and State of New York,

have invented a certain new'and useful Improvement in Machines for Perfo'ratingPa per, of which the following is a specification.

The object of our improvement is to produce a simple, cheap, and efficient machine for perforating 'paper,'and particularly for perforating such paper as is used to control automatio or mechanical musical instruments.

Our improvement is embodied in a machine in which a perforated music sheet is fed through as a pattern and an unperforated sheet is fed through correspondingly, the perforated music-sheet serving as 'a pattern and controlling devices which perforate the unperforated sheet similarly.

We will describe in detail a machine embodying our improvemenuand then point out thenovel features'in the'claims.

In the accompanying drawings, Figure l is a side elevation of a machine embodying our improvement. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a plan or top view with certain parts broken away and others shown in horizontal section. Fig. 4 is a transverse sectiontaken for one lateral part in one vertical plane'and forthe other lateral part in another Verticalplane. 7 L

Similar letters and numerals of reference designate corresponding'parts in all the figures. I

'A designates the frame of the machine. It may be made of ,wood or any other suitable material and will consist of side frames united by cross-pieces or stretchers. As here shown its side pieces comprise lower rails a and upper rails a In the lower rails are bearings a for the journals of' rolls B B to which a sheet of paper B is attached. When put into roller B it passes over punch-blocks O and beneath punches 0 There Will be as many of these punch-blocks and punches as there are rows of perforations to be formed in the.

paper B. All the punoh-blocks may be fastened to one support 0, made in the form of a bar with appropriate openings through it, and the punches will preferably all be supported in common bars 0 0 The bars 0 c supporting the punches, are immovable; but

the punches may have an independent longireciprocated transversely to said bars along suitable guides F by means of levers F fulcrumed upon a rod f. These levers, as here shown, are made in the form of elbow-levers and are represented as having their long arms made in two pieces riveted together; but this latter feature of construction is immaterial. The upper ends of these levers project through a rest G, supported by the rails a of the frame A. Springs f tend to raise these ends, and a perforated sheet H depresses them or allows them to rise, accordingly as perforate or imperforate portions pass. over them. The sheet Hwhen originally introduced is wound upon a roller H, which is journaled in the'rails a of the frame A, and is passed onward to a roll H by which it is taken up. This roll H may be moved by hand or otherwise. Above the rest G is a bar I, shown as connected at one end by a hinge z to one of the rails a of the frame A, and securedat the other end, which rests in a U -shaped bracket, by means of a catch 1'. The said catch t is pivoted at 4 to a bracket 1, having a U -shaped bearing 2, and comprises a toe portion 5, which rests upon the end of the bar I to retain it in position, and a handle portion'3, by means of which it may be operated. This catch is further provided with a curved elongated slot 6, through which passes a bolt, upon the end of which is fitted a thumb-nut '7. By

this arrangement the toe portion 5 of the catch can be adjusted so as to fit tightly upon the end of the bar I to hold it to its seat, and may be retained in this position by means of the thumb-nut 7, which is screwed up tightly against the said catch. The bar I may advantageously be made of concavo-convex form in transverse section, as represented in Fig. 2, to allow the adjacent ends of the levers F to rise into it. The sheet passes between the feed-rollers J J 2 and is drawn onward by them at a proper speed.

Each of the bars F has a notch on the under side, and the notches of all the bars will be above the punches C while imperforate portions of the sheet II are passing over the upper ends of the levers F Then the punches can rise each time the punch-blocks are raised by the toes of the cams E, and hence will not cut the paper. To avoid any misunderstanding, we will add that this upper movement of the punches will be produced by the unperforated sheet or strip B while resting above the punch-blocks.

W'henever any one of the levers F is permitted to rise through a perforation of the sheet H, the corresponding bar F will be reciprocated, so that its notch will be moved beyond the corresponding punch, and the latter then will be made immovable relatively to the bars 0 0 so that on the next upward movement of the punch-blocks such punch so held immovable will cut the sheet B. Thus the sheet B will be perforated to correspond with the sheet II.

The sheet B is moved along by means of feed-rollers K K between which it passes. Motion is correspondingly imparted to the feed-rollers J J 2 K K by means of ratchetwheels j on the rollers J K, pawlsj 70 coacting with said ratehet wheels and a lever L, which operates said pawls. This lever L is pivoted at one end, as shown, to the block D, and is fulerumed intermediate its ends in a slotted bracket by means of a slot in the lever engaging a pin Z, the slot in the said lever permitting the latter to slide longitudinally upon the pin as it oscillates. The rollers J K are each provided with a cam IV and lever X, by which to enable said rollers to be made to bear with greater or less pressure upon the sheets.

Although we refer to the term paper, we wish to cover the machine for perforating any analogous material. Although we have referred to the parts F as levers, it will be seen that they may be regarded as fingers, and that although we have spoken of the parts 1* as bars they may be regarded as stops for the punches.

In Fig. 1 we have shown the levers F as connected by means of rods S with levers S, constituting armatures for electromagnets S There will be a number of these levers and armatures corresponding to the number of the levers F The magnets may be mounted upon an L-shaped rail 5, suitably supported by uprights extending from the frame A. The armature-levers may be fulcrumed to this rail. The electromagnets are in circuit with a battery or other source of electricity S having a number of branches extending to the different magnets and provided with contacts 3 5 These contacts are normally separated. Above them may extend the manual-keys of an ordinary piano or organ, so that on the depression of the keys the branch circuits for different magnets will be closed, and this will cause the energizing of such magnets and the moving of the corresponding levers F Instead of operating the contacts 5 s by means of keys K they may be operated by means of a perforated sheet or analogous device of any kind. YVe intend to provide a machine with this electromagnetic mechanism, as well as the mechanism which is operated by the sheet II. The electromagnetic mechanism will be the better where a music-sheet of thin paper is to be used for the reproduction of others, whereas the mechanism controlled by the sheet II is suitable for music-sheets II of thick strong paper.

\Vhat we claim as our invention, and desire to secure by Letters Patent, is

1. In a perforating-machine, the combination of means for feeding an imperforated sheet, punch blocks arranged below the sheet and mounted to reciprocate in guides upon either side of the machine-frame, a retary shaft journaled in bearings below the punch-blocks, cams on said shaft adapted to act upon the under side of the punch-block mountings to reciprocate the same, a stationary support above the punch-blocks, a series of punches loosely mounted in said support, a series of locking-bars arranged to move freely back and forth in guides above said support, a plurality of elbow levers tulcrumed upon a common rod and each having its lower end connected to one of the lockingbars and its upper portion bent forward horizontally and terminating in a vertically-projecting arm or point, a table or rest G, up through which the points of the levers project, an arched bar I, arranged above the rest and hinged at one end to the machine-frame, and a perforated sheet arranged to travel between the said arehed bar and rest, as and for the purpose described.

2. In a perforating-machine, the combination of a roller for feeding an imperforated sheet, punch-blocks and punches for perforating the same, the reciprocating notched bars and their connected elbow-levers, a roller for feeding a perforated sheet, ratchet-wheels on said rollers, pawls coactin g with the ratchet wheels, and a lever for operating the said pawls, substantially as described.
