GEORGE B. KELLY, OF BOSTON, MASS, ASSIGNOR TO THE MECHANICAL ORGUINETTE COMPANY, OF NEW YORK, N. Y.

APPARATUS FOR CUTTING PATTERN-PLATES TO BE USED IN THE MANUFACTURE OF PERFORATED MUSIC-SHEETS.

SPECIFICATION forming part of Letters Patent No. 223,676, dated January 20, 1880.

Application filed June 14, 1879.

To all whom it may concern Be it known that I, GEO. B. KELLY, of Bos ton, in the county of Suffolk and State of Massachusetts, have invented a new and useful Apparatus for Cutting Pattern-Plates to be used in the Manufacture of Perforated Music-Sheets, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to the production of patternplates to be used as guides for the cutting-punches, and to determine the loca "tions of the several perforations to be made in the manufacture of perforated music-sheets for use on mechanical musical instruments.

I have found by practical test that the per forated music-sheets now in quite general use in connection with mechanical musical instruments can be produced at a much less cost by cutting the perforations .while the sheets of paper are wet or in a damp state, as described in another application ofeven date herewith;

' but as the strips of paper, when in such damp state, are considerably wider than the original music-sheet cut by the musician who arranges the music, and which is to be used as a guide in producing a permanent pattern having sufficient thickness and strength for use in cutting large quantities of said music-sheets, it be- 0 comes necessary to out the permanent pattern of a width corresponding to the Width of the sheets of paper when wet.

To this end my invention consists in the use, in combination with a cutting block, of a 3 5 clamp for holding the original music-sheet and I the sheet of straw-board firmly in position, one upon the other, so that there can be no slip between them, and a gage provided with a series of slots corresponding in number to the number of the longitudinal rows of holes in the original or pattern music-sheet, and a distance apart greater than the lateral distance between the openings in said original music-sheet, as a means of determining the 5 positions transversely of the perforations to be cut in the straw-board.

Figure l of the drawings is a plan of my improved apparatus with the original musicsheet in position on the straw-board sheet, and

showing the straw board sheet partly cut. Fig. 2 is a vertical longitudinal section on line- 00 x on Fig. 1. Fig. 3 is a vertical transverse section on line y 3 on Fig. 1. Figs. 4 and 5 are, respectively, a plan and edge view of the strawboard pattern sheet partly out, and Figs. 6 and 7 are, respectively, an end view and a longitudinal section of a punch used in cutting the peforations in the straw-board.

A is the main cutting block or anvil, made of wood, preferably with the grain of the wood perpendicular to its upper surface, and in practice made of sufficient length and width to support the whole of the sheet to be out thereon. The upper surface of the block Ahas secured thereto the thin plate or sheet B, preferably of straw-board, upon which is placed the material to be cut, and which receives the edge of the cutter as it passes through the material to be out.

Heretofore the cutting has been done di- 0 rectly upon the end of the wood; but it has been found that in a short time the surface of the wood becomes unfit for use, and it becomes necessary to plane off the whole surface of the block to a sufficient depth to remove the iudentations made therein and obtain a good cutting-surface again. This is somewhat expensive, on account of the labor attending it but in addition to that there is the loss of the use of the apparatus whilethe block is being planed off, and the block is being gradually but surely worn away, and after a while has to be renewed altogether.

The straw-board sheet is comparatively inexpensive, makes a good cutting-surface for a considerable time, and when no longer fit for a cutting-surface is of some value foruse for other purposes, and may be readily removed from the block and another sheet secured thereon with but a few moments delay.

O 0 are a pair of side rails, connected together by the cross-ties D D, so as to form a frame, which is clamped to the block A by means of the hasps E E and pins FF, in such a manner that the bars or tiesD D shall bear with considerable force upon the original musicsheet G and press it, with the straw-board sheet H, hard upon the cutting-block, the rails O O projecting above the upper surface of the strawboard sheet H sufficiently far to serve as guides for the gage I as it is moved from one position to another.

The gage I consists of the metal bar a, having cut in its edge a series of slots, Z), corresponding in width to the width of the hole 0 in the original music-sheet G, and in number to the number of longitudinal rows of holes formed in said sheet, and the two guide-bars d d, and is placed upon the original or pattern in usic-sheet G with the outer edges of the guide- .bars 0 0 bearing against or guided by the rails O O.

The operation of my invention is as follows:

The original music-sheet G being placed upon" the straw-board sheet H and about centrally thereon, as shown, the two are placed upon the straw-board covered cutting-block A, and the clamping-frame (J O D D is placed in position on said block and secured thereto by the hasps E E. The gage I is then placed in position between the rails O 0, with theslots b b over holes in the music-sheet G, though not exactly coinciding therewith widthwise of the music-sheet. Ahole is then punched through the straw-board by placing the cutting end of a punch similar to the one shown in Figs. 6 and 7 in one of the slots 1), where the hole in the music-sheet indicates thata hole is required, and giving it a blow with a mallet. This is done at each slot b where an opening in the pattern-sheet is seen, using such a punch as the length of the perforation in said patternsheet indicates should be used, the punch cutting out more or less of the stock .of the pattern-sheet upon one side or the other, or exactly corresponding with the perforations in said sheet, according as the perforation is in the center of the width thereof or farther removed from said center toward one side or the other.

When all of the holes have been punched that are required in that transverse row or line, the gage I is moved to the next transverse row, and the operation is repeated, and so on till the whole tune is cut.

The dotted lines across the openings 0 in Fig.

1 indicate the outer limit of said openings in the pattern-sheet Gr beibrecutting the holes in the straw-board sheet, as above described.

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is 1. The combination of the cutting-block A, pattern music-sheet Gr, clamping-frame G D, and the gage I, all arranged and adapted .to operate substantially as described.

2. As a means of determining the proper position of the perforations in a pattern-sheet for cutting perforated music-sheets While in a wet state, the combination of a pattern music-sheet of the desired Width to be used in the instrument to determine the longitudinal distances of the openings, and a gage provided with a series of slots corresponding in number and width to the number of longitudinat rows of openings desired and the Width thereof, to determine the lateral position of said openings, substantially as described.

Executed at Boston, Massachusetts, this 13th day of May, A. D. 1879.
