ll/lCHlNl- FOR PERFORATING PAPER, 8.1.0.

SPECIFICATION forming part of Letters Patent No. 699,649, dated May 13, 1902.-

Application tiled J'uly 23,1901.

To cI/Z whom z'ft may concern:

Be it known that I, JAMES B. BROW, a subject of the King of England, and a resident of the city of New York, in the county of New York and State of New York, have invented certain Improvements in Machines for Perforating Paper and the Like, of which the tollowing is a specification.

This invention relates to improvements in Io machines for perforating paper or the like by the aid of a pattern-sheet which determines the extent and location of perforations to be produced in the desired sheets.

The invention is primarilyintended for the I5 production of tune-sheets for use in automatic or mechanically operated musical instruments, whether for controlling the passage of air in reed instruments or for governing the action of mechanical, electrical, or other appliances by the aid of which pianofortes and like instruments may be mechanically operated.

The invention may also be used for the production of perforated sheets in determined patterns or systems for other purposes.

In the accompanying drawings, Figure 1 is a plan of a machine illustrating this invention. Fig. 2 is a side elevation of the same, Fig. 3 is a transverse section of the upper 3o part thereof, on a larger scale, on the line 3 3,

Figs. 1 and 2. Fig. 4 is a partial longitudinal section on the line 4 4, Figs. 1 and 3, also on a larger scale. Figs. 5 and (l are detail vertical sections showing the perforator-controlling mechanism in two positions, as hereinaftcr described.

A pattern-sheet 1 is passed from roll 2, beneath a roller 3, between adjustable lateral guides 4 4, secured to rods-5, which are adjustable in position by nuts G and held by springs 7, in order to locate the pattern-sheet accurately widthwise of the machine to adapt the holes therein to vertical selecting-rods 18, which work in conjunction therewith.

From the guides 4 the pattern-sheet is passed between bars 8 and 9, Figs. 3 and 4, the bar 9 being hinged at 10 and held down upon the pattern-sheet 1 by a lever 11, hinged at 12 and held in place by a catch 13, pivoted 5o at 14. By releasing the catch 13 and lever 11 from the bar fl it can be swung up against Serial No. 69,443. (No model.)

the rest 15, as shown in dotted lines in Fig. IVhen swung down, it is guided to place by a pin 16, fitting into a hole in the bar 9.

` Guided by holes 17 in the bar'S are a series 55 of vertical selecting-rods 18, pivoted to a series of levers 19, fulcrumed at 20 and actuated by a series of springs 21, causing the respective rods 18 to rise whenever a hole is presented in the pattern-sheet 1. Whenever 6o desired, the whole series of rods 13 can be held down by a bar 22, extending across the levers 19 and secured to arms 23, pivoted at 2O and held in position by a spring 24, drawing the lever 23 against a cam 25, capa 65 ble of being turned to hold the bar 22 up or down. The entire range of selecting-rods are thus held down out of the way when it is necessary to remove the pattern-sheet or shift it without operation of the machine.

Bearing against the free ends of the series of levers 19 are a series of levers or arms 26, pivoted at 27, actuated by springs 28, and formed at their lower endswith recesses 29 and projections 30.

For perforatingthe paperaserics of punches 32 are employed, equal in number to the selecting-rods and to t-he lines of perforations desired. Said punches are provided with shoulders 33 and with pins 34, by which they 8o are guided in vertical paths. When the levers 26 are in the position shown in Fig. 4,

' the punches move up and down in the recesses 29 without obstruction. Any desirable number of sheets 35 to be perforated are taken 85 from rolls. (Not shown.)v For the purpose of illustration two such sheets are shown; but in practice any desirable number of superposed sheets may be fed through the machine and Vpunched simultaneously. The 9o lower ends of the punches rest upon the paper sheets 35 to be perforated, which pass between the die-frame 36 and the die-plate 37 and are guided in the die-frame The dieframe 36 and die-plate37 are securedto a 95 swinging frame 38, pivoted at 39 tothe frame 40 and receiving vertical oscillating motion from pitman 41 and eccentrics 42 on the main shaft 43.

The paper 35 is moved up by the oscillating 10o die-frame 36 37,carryin g up the punches when the position of the recess 29 in the respectivo levers 26 permits the upper end of the punches to move into the said recess, in which case the paper will not be punched.

If an aperture in the pattern-sheet 1 permits a selecting-rod 18 to rise, the end of the lever 19 passes up out of range with the lug 3l on the lever 26, which allows the said lug to pass under the end of the lever 19 and the projection 30 on lower end of the lever to pass over into range with the upper end of the punch 32, as shown in Fig. 5, the lever 26 resting against a fixed transverse bar of the frame. Then as the die-frame 3G 37 carries up the paper sheet it is punched by reason of the respective punches 32 coming in contact with projections 30 of the levers 2(5,while all the punches corresponding with selectingrods 18, which are depressed by the absence of perforations in the pattern sheet, pass freely up into the recesses 29, as shown in Fig. 6, so that the paper is not perforated at these points. As the die-frame descends the punches are withdrawn from the paper by collars 33 thereon, resting on a bar 44, secu red to hangers 45, pivoted by each end at 4G to rods 47, extending down from a part of the frame 40, and provided with screw and nut 48 for adjusting the height and fastened by a screw and jam-nut 4 9. After the die-frame has descended the levers 26 are carried back to the position shown in Fig. 4 by means of a bar 50, secured to the bell-crank levers 51, pivoted at 52, and provided at their opposite ends with rollers 53, working in camwheels 54. The levers 26 are carried back far'enough to permit the end of such of the levers 19 as the pattern-sheet shall determine to be forced down past the lugs 31 on the upper ends of the levers 26, the patternsheetv being moved downward by a swinging frame 55, on which the bars 8 and 9, support 15, lever 1l, catch 13, guides 4, rod 5, nuts 6, and springs 7 are mounted. The swinging frame 55 is pivoted at 56 and provided. with an arm 57, having a roller 58, engaging a camwheel 59.` The parts being in the position shown in Fig. 4, the bar 504s next drawn away from the lower end of the levers 26, permitting the lugs 3l on their upper ends to bear against the ends of such levers 19 as are forced down bythe pattern-sheet and to pass under the levers which remain up, as shown in Fig. 5, by the presence of a perforation in the pattern-sheet, causing the projections 30 at the lower ends of the levers 2G to stand in a position to check the upward movement of the respective punches 32. After the dieframe. 3b' has moved up and the paper is punched the frame 55 is moved up to withdraw the pattern-sheet from the selectingrods 18 and permit the pattern-sheet to be fed forward, the upward movement of the respective levers 19 and the selecting-rods 18 actuated thereby being limited by a square shoulder on the heel of each of said levers coming in contact with a fixed abutment-bar '132 on the frame, as shown in Fig. 4.

The pattern-sheet as it passes from between the bars S and 9 is passed under a rod (50, extending across the machine, with cranks 61 at the ends journaled in the frame 40, permitting the rod to be turned and held in an adjusted position by a spring G2. The pattern-sheet passes over a roll 63, having pins (i4, engaging eyelets 65 in the pattern-sheet near each edge, which serve to draw the said pattern-sheet forward. The roll 63 is provided with a ratchet-wheel 66, turned bya pawl 67, held in gear by a spring 68 and mounted upon a lever 69, pivoted at 70, having a roller 71and spring 72, serving to press the roller 7l against a cam 73, which is secured to the shaft 74, on which the calnwheels 54 and. 59 are mountedk and which is constantly driven by a chain-wheel 75 through chain 7 and chain-wheel 77 from the main shaft 43. An idler 7S is provided for'adjusting the tension on the chain by securing its journal 79 in one of a series of holes formed in a bar 80, secured. to the frame 40, or by other suitable means to keep the chain taut. The shaft 43 is provided with a tight pulley 8l and a loose pulley 82 and is driven by a belt 83 when shifted to the tight pulleySl by means of the belt-shifter 84, which is provided with a rod 85, extending to the frontof the machine and held in place by an arm provided with a guide-pin 8G, passing through the bar 8O of the frame. From the roll G3 the pattern-sheet passes under a roller 87 and forward to a take-up roll SS, which receives a step-by-step rotary movement imparted fromv a pawl 89, pivoted to an arm 90, fulcrumed on the shaft of the take-up roll 88 and taking into a ratchet-wheel 91, keyed on said shaft. The lever-arm 90 receives a reciprocating movement from a spring 92 on a rod 93, sliding through an aperture in a lug 94, pivoted on the end of the arm and pivoted at its rear end to a crank-pin 9S, carried by a crankwheel 99 on the end of the shaft 74. The spring 92 bears backward against a collar 9G, fixed to the rod 93, and forward against the lug 94, so as to apply a yielding thrust movement to the arm 90 at each rotation of the crank-wheel 99. Backward rotation of the rtake-up roll 88 is prevented by a detent-pawl 97. The pattern-sheet is thus kept under tension, and at each stroke it is taken up step by step,as permitted byits movement through the machine effected by the feed-roll 63.

The paper sheets 35 to be punched are passed beneath a roller 100 over a plate 101, having lateral guides 102 which extend forward nearly to the die-frame 3G, where knives 103 are secured to the frame 40 on each side of the machine, and a cutting-block 104 is secured to the swinging frame 38 beneath the paper, so that as the frame 38 rises the-edges of the paper will be cut at every upward movement of the frame 3S. The waste edges that are trimmed from the paper are passed to each side of the machine around a rod 105, secured to the frame 40 and provided with a ICO IIO

guide-pin 106. The waste edges are passed back from the rod 105 over a roller 107, which is secured to the shaft of roller 100, a roller 108, secu-red on each end of shaft 109, rest-ing on the Waste edges. An additional weight 110 is attached lo shaft 109 to increase the pressure of the roller 108 upon the waste edges to carry them away. The perforated sheets 35 are carried beneath a guide-rod 111, and one or more of the sheets pass between feed-rollers 112 113, while anotherone or more sheets are passed to similar feed -rolls 111 115. The roller 112 is rotated step by step by a ratchet-wheel 116, keyed on its shaft, and a pawl 117, taking into said ratchetwheel, pivoted on a lever 118 and held in engagement by a spring 119. The lever 118 is fulcrumed at 120 and is provided at its other end with a roller 121, held by spring 122 in contact with a cam 123 on the shaft 74, which imparts step-by-step movement to the feedrolls, so as to carry the paper through the machine at a speed corresponding with the feed movement imparted to the pattern-sheet by the feed-roll 63. A' detent-pawl 124 and spring125 prevent backward rotation of the feed-rolls 112 113. The second pair of feedrolls are driven from the front through the medium of gearing 126.

The feeding-pressure between the respective pairs of feed-rolls is maintained by cams 127 on the ends of shafts 128, bearing on the boxes of the respective upper rolls. Keyed on the shafts 128 are handles 129, which when turned in one direction cause the prominent faces of the cams to bear on the roller-boxes, so as to press the rolls together, and when turned back relieve the pressure, so as to leave the paper free. The shafts 128 have their bearings in slidable boxes 130, held down adjustably by screws 131, so as to regulate the pressure.

The slotted fulcrum-bar 132 and the rod on which the levers 19 and 23 are mounted, the fulcrum-rod of the levers 26, and the rods to which the actuating-springs of the levers 19 and 26 are attached are preferably fixed in a frame 133, which is removable from the main frame, so that the finer operating parts may be taken out bodily for inspection or repair.

In operation the pattern-sheet 1 is fed forward step by step, as described, and the combined sheets 35, having a corresponding stepby-step feed movement imparted to them by the drawing-rollers 112 113 and 114 115, pass under the edge-trimming knives 103 and between the guide-frame 36 and die-plate 37 beneath the transverse range of punches After each feed movement of the sheets they are moved up by swinging movement of the frame 38, imparted by the eccentrics 42 and pitmen 41, with the result that the paper is perforated by such of the punches 32 as are held down by contact with projections 30 on the corresponding levers 26, which have been permitted to assume the position shown in Fig. 5 by the upward movement of the cor- 32 these punches will be carried up by the sheet 35, and the sheet will not be perforated at these poi nts. After each perforating movement the vibrating bar 50 restores to normal position (shown in Figs. l and 6) all of the levers 26 which have been shifted, and all the selecting-pins which have ascended drop to the position shown in Fig. 4, in readiness for the next feed movement and with their attached levers 19 opposed to theshoulders 31 of levers 26, as shown.

Having thus described the invention, l declare that the following is what I claim as new therein:

l. The combination of a suitable perforated pattern-sheet, the vibrating guide-bars 8, 9, therefor; a range of selecting-rods 18, depressed bythe contact of imperforate parts of the pattern-sheet; a range of spring-pressed arms 19 applying upward pressure to the respective selecting-rods; a range of perforating-punches 32 corresponding to theselecting-rods in number and relative position; a range of spring-pressed.vibrating arms 26, controlled in position by the depression of the corresponding selecting-rods 18 and arms 19A and constructed with projections and depressions, which are respectively presented to the punches so as to render them operative only when the corresponding selecting-rods are advanced by the presence of a perforation in the pattern-sheet, the vibrating frame 50, 51, for ret-racting the arms 26 to permit descent of the selecting rods; and means for forcing paper to be perforated against the punches, substantially as described.`

2. The combination ofthe spring-pressed oscillating levers 26, having protuberances 30 and recesses 29 at their free ends and projecting lugs 31 at their fulcrum ends; a'range of selecting-rods 18 adapted to bear endwise against the pattern-'sheet and to enter perforations therein; a corresponding range of spring-pressed levers 19 controlled in position by the respective selecting-rods and controlling the corresponding levers 26 by contact of the lug 31 thereon; a correspondingrange of perforating punches 32 controlled. in ,their endwise movement by the opposition of the protubeances 30 or recesses 29 ofthe Vlevers 26; and means for pressing the paper 35` against the punches and thereby perforating the paper by such of the punches as are opposed by the protuberances 30, as explained.

3. The combination of corresponding ranges of selecting-rods 18 and perforating-punches 32, vibrating guide-frames 8, 9, and36, 37 for IOO IZO

the pattern-sheet and paper respectively; in- A tei-posed spring-pressed levers 19 and 26 controlling the movement of the punches by the cylinder 63 and take-np roll 88, and .means for operating the same, substantially as described.
