To all whom #may concern.-

Be it known that I, GEORGE B. KELLY, of

Boston; in the county of Suffolk and State ofy specially prepared strip,` or. sheet, called a stencil, whichnecessitates that such stencil shall be of a width and thickness much greater andV of stronger material than the sheet or strip of paper to be perforated for the music sheet, -making these stencils more or less bulky and cumbersome; and with alarge number of such stencil sheets on hand requiring a great deal ofV room in which to store and keep them, Whereas in the present machine any perforated sheet can be used for the stencil as for instance the perforated music sheet itself, and `therefore not requiring special preservation for stencils, enabling the machine for perforating the strips or sheets to bemade much smaller, more compact, takingyup much less room 'and at much less expense, advantages in the preparation of such perforated music sheets las are obvious to parties interested in such manufacture. y The invention consists substantiallyln combination with means for perforating strips or sheets of paper or othervsuitable sheet matef` rial, of a suitable wind or exhaust bellows, a series of. pneumatic bellows communicating therewith, and a series of electro magnets electrically connected therewith, and all constructed and-arranged-for operation O'n a sheet of paper or other' suitable material all substantiallyas-hereinafter described; and the invention `also consists .of the construction. and arrangement of parts in such machine all: substantiallyas hereinafter fully described.

In'the accompanying sheets offdrawin'gs is illustrated a machine. for perforating sheets of paper or other sutablematerial constructed 'chine scription herein.

In the drawings A represents a horizontal bed plate which rests on'legs or uprights B which support the various parts of the ma- Fig. 9

its upper side an upright box C having a 'chamber D, making a wind chest, similar to On this bed at the left, is secured on a wind chest of a reedlorgan, and'communieating by a passage E, through the bed plate A with a bellows F, secured to the under side of the bed plate, and arranged-to be operated4 in the usual manner of operating bellows for reed organs, and in such manner as preferably to exhaust the air from the wind chest chamber D, and needing no particular de- This wind chest extends transversely onthe bed, and arranged centrally and vertical-ly, therein is a board GrV its upper part extending up through and a short distance above the-top H, of the wind chest, and connected by its two ends to the endsJ of the -wind chest and of a thickness to leave an air space between its sides and the side -walls K of the wind chest and extending down nearly to the bottom of the bed leaving 'an air space L thereunder,` between it and vthebed, which has free communication `with bothsides, and .into whichthe bellows passage E communicates. In this board G are a row of vertical air passages M, whichopen to the outside at its upper or surface `edge as yshown in section in'Figs. 2 and 3, and in plan view vin Fig. 1, whichlpassages at their lowerends alternately extend to the rghtand left, through lthe side of the blocky as at a, and each opening into a separate pneumatic bellows N vertically secured'to both sides of the board in two horizontal rows.' The upper IOO rows of these pneumatic bellows have their movable boards, hinged at their upper ends as at t, and the lower rows at their lower ends as at d, and each movable board has the usual escape air passage e. Each pneumatic bellows has a separate spring P secured to a rail f of the board G, at its hinge end, the free ends g of the springs bearing upon the respective movable board of its pneumatic bellows to keep it closed and in its normal position. These pneumatic bellows are arranged on the board so that they will be alternately in different vertical planes transversely along the length of the board, one af ter the other, as shown, for one side of the board in Fig. 4, where h, is the first bellows, m the third bellows, n the fifth bellows,rthe seventh bellows; the second, fourth, sixth and eighth bellows being Von the other side of the board but on different transverse vertical planes, that is, `the second on a transverse vertical plane between the first bellows and third bellows, the fourth bellows on a transverse vertical plane between the third bellows and the fth bellows, and the sixth on atransverse vertical plane, between the fifth bellows and the seventh bellows, and so throughout the whole series. This arrangement of the pneumatic bellows allows the air passagesto be close together, to occupy a small space, substantially so that four passages will .occupy the space along the length of the board ol" a width kof one bellows, whereas arranging the bellows all in one row would separate the air passages `accordingly making `the board much longer, andconsequently the machine much wider.

`Q is a roll adapted `by its journals ttoturn in bearings in two cross bars R, secured to the wind chest `at each end, and S is another rolladapted by its journalsu to turn in bearings in the cross bars R, and extending from one roll to the other is a sheet, or strip of paper T, its ends attached to the two rolls, and

between the two it lays on and is arranged to pass over the upper surface e of the boardG, over the open ends of the passages M, it having perforations w through it, and which sheet is the stencil, or pattern sheet for the present machine. `Thisstencil sheet o r pattern is perforated in accordance with the musical tune as desired, and can be of a width to have as many longitudinal rows of perforations as there are air passages M in the board G, the longitudinal rows of perforations being the same distance apartas the air passages M. At the opposite end of the bed plate are secured two nprights U, one each side ofthe same, and between the two, a

is a plate or bar Vset up edgewise, arranged to slide up and down in gugideways a: on the innerlside of each upright U. Pivoted tothe under .edge of this plate at a are two ytoggle 1 levers "W, each near the end Vof the plate, which are pivotedby their lower ends" at b to across bar Y of the bed A. Pivoted `by one end to the central pivot d of each toggle lever is a rod B', which by its other end is pivoted to a crank arm C of a horizontal shaft D' adapted to turn in bearings e secured to the uprights. This shaft extends beyond the upright at one end and outside thereof has a pulley E secu red thereto having a belt F which is arranged to be connected to any suitable driving power for operation thereof. Rotating the shaft Dv the toggle levers W at their central joint are moved forward and backward of the central vertical plane of the bar V and in such movements the bar is moved up and down,it1nov ing up and down twice to each revolution of the crank shaft. Above this movable bar are a series of bars or rods G arranged in a horizontal plane, each arranged to slide back and forth in separate `guideways or vertical slots c in two plates f g arranged transverselyof the bed and secured by their ends between and to the two uprights U.

In the under side or edge of each slide bar G is a notch h' through its thickness which is longer than the thickness of the movable bar V, and when `these slide bars G are in their normal positions the notches are just above the upper edge of the movable bar, and the notches are of such depth that if the bar is moved up to its highest point it will enter the notch, but be free of and not touch the lslide bar, as shown insection fin FigrS, butif thisslide bar is moved forward intothe position shown in Fig.i5, and the baris then raised the part m of the slide bar beyond the notch then beingover the bar V, it will cause the `slide bar to rise with it.

Attached to the rcarend of `each slide G `bya link e2 is the free end of aseparate spring R secured by its other end to cross barS of the uprights. Aboveeach ot' theseslide bars is anyupright punch or die lI each of which is arranged to move freely up and down in a separate slot or guideway n' in a cross bar J of the uprights.

`The upper portion of `each punch is smaller incross section and extends upinto a socket `or opening fr in a horizontal ,plate K secured to the cross bar s which smaller portionleaves .on one side a shouldert' on which rests the free end u of a `flat spring Lsecured at 'v' to ,a cross bar M of theuprights, which bears and presses the punch down toitsnormal position which is `when a projecting pin w' of the punch rests on a cross `barN and in such position the punch is a slight distance above the sliding bar G as shown in side view in Fig. `8, so it will not touch or rest thereon. `Resting on top of the plate K is a cross bar P having a central longitudinal slot Y `through it, and a plate Q on its under side provided with a series of openings c2 therethrough, which are j ust overor vertically co-` incident with the openings r in `the under plate K. 'This plate Q `is the die plate` and4 it and its bar P have two vertical holeswhich fit over `vertical pins d2 on the plate K', by`

which the upper bar with its die plate is ICO IIO

placed in proper position over the lower bar. Between these two plates K Q is arranged to travel in the direction of the arrow u2 the paper sheet T which is to be perforated which passes to and winds upon a rollU turning in bearings in the cross bars V. This roll has its journal f2 extend beyond the cross head and on its outer end has asprocket wheel W with which engages a sprocket chain A2 which chain engages with another sprocket wheel B2 secured tothe journal tof the rollU at the other end of the machine, carrying the stencil or pattern sheet. l

C2 are electro magnets and they'aresecured respectively to the one side, Fig. 2, of yfour separate transverse. upright boards D2 of the bed A. l

In the drawings there are only tive electro magnets shown, but in the practical operation of the machine there are as many as there are air vpassages M in the board G, but only five'are deemed necessary to show in the draw'- ings,'more would only be duplicates.

Pivoted at g2 respectively tol three of the upright boards D2 and another upright board E2 are vertical arms or levers F2 to the lower part of each of which is secured centrally at h2 an armature G2 which is located in proper position for the electro magnet in front of it. The upper end of each lever F2 is connected by a pin m2 to one end of a strip or rod H2, which is connected by its othergend by a pin n2 to the end of a slide bar G. This connecting strip is of a length, that when connected to an armature lever F2 and a slide bar Gr, the slide bar spr-ing R will hold the slide bar back and Kthe'lever so that its armature will be away or: n disconnected from its electro magnet, which is itsnormal position, as shown in Fig. 2, and in such position thenotch of the slide bar will be directly above the plate Vias shown in Fig'.'8.

Opposite each screw r2 securing the pneumatic bellows spring P as shown, in Figs. 2

and 3, is aI plug J2 having a headA t2 which closely ts in a socket u2 in the side-board of the wind chest, and extends a short distance therein and passing through it is an electric f wire K2 the endg being coiled a little as at @2,

l 5sA and when the plug is in place, bearing upon the head of the spring screw r2.

L2 is a screw screwing. through the wind chest side board in to the chamber and in line verticallywith a pneumaticbellows spring` P and oppositeto its free end as shown in section in Figs. 2'and3'. To each ofthese screws p L2 isconnected a separate electric wire M2,

and these screws with the springs P, are thev electr'odes,"and the separate-wires are connected with an electric battery to make an electric circuit.

With the stencilstrip T upon theroll S andv ,connectedv by one end to the other roll Qand `the strip T of paper on its proper'rolls'to be perforated in` accordance with th'e'stencil.`

strip, and with the electric circuit all complete, the machine is ready for operation. v

The main bellows F are operated in the usual manner which exhausts air from the wind chest, causing all the pneumatic bellows to close. Motion is then communicated to the pulley P2 causing the roll Q to turn which draws the stencil strip over the upper surface of the board G in the direction of the arrow 102 Fig. 2 and winds it upon the roll Q; at the same time through the sprocket wheel B2, chain A2 and sprocket wheel W of the roll'U motion is communicated to it in the direction of the arrow y2 Fig. 2, which causes the paper strip to travel between the plates K Q over the perforations in the lower plate, and which moves with the same speed that the stencil sheet does over the air passages, the two rolls and their sprocket wheels, being of corresponding diameters. The crank shaft D is also revolved at the same time which causes the board to reciprocate vertically and preferably quite rapidly. As the stencil strip travels over the board G, and a perforation w, therein, comes over an air passage M, air vpasses quickly down through it into the pneumatic bellows N, with which it communicates, opening the same, which presses its ,spring P back against the screw L2 making electric circuit, by which the `electro magnet infsuch circuit attracts its armature, swinging its lever F2 on its pivot, the upper arm of the lever pulling upon and moving the slidebar G for- VWard against its spring until its notch h. is

moved away from, and its thick portionm in the' next upward movement of the'board U pushes'the notched bar upward` and forces 4the punch pH up and through the paper sheet T making a perforation therein; as soon as the perforation w in the stencil sheet passes by the air passage and the unperforated poris cutoff fromentering the passage which y over, the movable reciprocating plate U which tion of the stencil sheet comes thereover, air

circuit, closing its bellows and releasing thev armature to the electro magnet, allowing the spring of the slide bar to return it to its normal position, with its notch over the movable board so that the next upward movement of the board, i-f a perforation'w, is not over the airpassage, will-not operate upon the punch,

but when the next perforation tu, comes over the air passage as before, the partsare again operated as described and another perforationv made in the paper sheet T and so on. Thus whenever a'perforation in the stencil sheet comes over an air passage in the board G, a corresponding perforation is made in the paper sheet T as described. l' i In theupright board of each armature is ay screw m2 projecting therethrough against the end of which the armature lever abuts, when `away from the magnet to limit its backwardv movement, and by which such movement can' be regulated by'turning thel screwin or out.

The spring to each pneumatic bellows is bent so that when its free end is bearing upon the bellows, its other end, back of its securing screw will bear upon the cross bar, the part where the screw passes through it being bent so that it is raised from the bar, so that by turning the screw in or out lthe pressure ofthe spring can be increased or diminished as desired upon the bellows, and when desirous of regulating the spring, pulling out the plug .I2 it can easily be reached by a screw driver, and when turned as desired, the plug is inserted again and electric connection `made with the spring as before. This is advantageous, as it makes an easy and convenient way of regulating the pneumatic bellows springs.

The rear end of the notch in each slide bar is beveledias atau2 so that if the slide har is pulled forward when the bar is moving upward, it will easily ride up over its edge in its forward movement, so the bar can operate upon it.

In order to use a narrowstencil sheet, or the perforated music sheet which is quite narrow, and therefore reduce the width of the machine, the pneumatic bellows are ar-` rangedxin two horizontal rows on both sides of Lthe air passage board, and in the order stated,and theelectro magnets are arranged in four rows on four separate supports, and their armature levers correspondingly, which brings them allcompactly together laterally, and all connections between the air passages and the punches in parallel lines, or substantially so. Each electro magnet is connected electrically to a separate pneumatic bellows, substantially as follows; looking at Figs. 1 and 6 more particularly; the first magnet a3 in the first row with the iirstpneumatic bellows m, and its lever with the first punch a4; the first magnet ha of the second row, with the second bellows, and its lever with the second punch h4; the first magnet d3 Of the third row with the third bellows n and its lever with the third punch d4; the first magnet e3 of the fourth row with the fourth bellows, and its lever with the fourth punch et; the second magnet f3 of the first row with the fifth bellows fr, and its lever with the fifth punchf; soon with the second magnet of the second, third, and fourth rows, the third magnet of the first row, and so on throughout the whole series, there being as many magnets in the four rows as there are air passages in the board.

.If desired the pneumatic bellows can be arranged in a larger numberof rows, also the electro magnets, which .would obviously reduce the width of the stencil, but the arrangement described and shown is satisfactory in its results.

The cross bar P having the die plate Q is held firmly in any suitable manner from upward movement so that it will hold the paper T against the punch in its Operation.

Having thus described my invention, what I claim is l. In a machine for perforating sheet maon said punch and a plate or bar adapted to move u p and down in suitable guideways for operation on said slide bar for the purpose specified.
