MACHINE FOR PUNCHING NOTE-SHEETS'.

SPECIFICATION formingpart of Letters Patent No. 673,586, dated May "-r', 1901. Application le. February 23, 1901. 'Serial No. 48,574. A(No modem To all whom it may concern.-

Be it known that I, HARRY M. SALYER, a citizen of the United States, and a resident of the city of New York, borough of Bronx, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Punching Note-Sheets, of which the following is a specication.

This invention relates to improvements in machines for perforating music-sheets such as are used for automatically-operated musical instruments.

The object of my invention is to provide a new and improved machine of this kind which is simple in construction, rapid in operation, and reliable in action.

In the accompanying drawings, forming a part of this specification, and in which like letters 0f reference indicate like parts in all the views, Figure l is a plan view of my improved music sheet perforating machine. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical longitudinal sectional view of the same on the line 3 3 of Fig. l. Fig. 4 is a detail view.

The entire mechanismis mountedin a frame A, composed of two side uprights, and in said frame a horizontal dieplate B is held, in which are held a series of transverse rows of dies C, an opening C' extending from each die down through the die-plate.

Directly above the die-plate and separated from the same only by a distance slightly greater than the thickness of the paper to be punched is located a punch-plate D, in which a series of vertically-recip'rocating punches E lare mounted in line with the dies, each punch being pressed upward by a helical spring E', which presses the head F of the punch against a transverse stop rail F', secured in the frame A.

Vertically and centrally above each punch a cylinder G is secured, which contains a vertically-reciprocating piston-rod G', secured to a piston inv the cylinder. (Shown in dotted lines.) Each cylinder G has a valve-casing H, and said valve-casings are in communication with a series of compressed-air chambers I, connected with a compressed-air-supplypipe J.

The sheet of paper a to be perforated is drawn through the space between the dieplate B and the punch-plate D by the two friction-rollers K and L, the latter being covered with rubber and the former being fixed on a shaft K', carrying a belt-pulley K2 and a sprocket-wheel M. The roller L is mounted in a vertically-sliding frame N, which can be adjusted, by means of a screw N', to produce the desired pressure and friction on the paper ct.

Each valve-casing H is connected with a vent-pipe O, which vent-pipes have their upper ends held in a series of transverse slats O', in the upper surfaces of which the upper end openings O2 of these vent-pipes appear. The upper end of each vent-pipe is closed by a valve P, pivoted at P' and pressed upward by a spring P2, which spring also presses a beveled nose P3 on the valve into a slot R' directly above it in a slat or plate R, over which slats or plates R the matrix-sheet b, of paper orsheet metal, is drawn. This matrixsheet is unwound from a roller S, passes over a guide-roller S', and after passing over the slats or plates R passes between two frictionrollers T and U, the former being covered with rubber and mounted in a vertically-sliding frame T2, which can be adjusted by means of a screw T'. The shaft of the rollerU carries a sprocket-wheel U', over which a chain U2 passes, which also passes over the sprocket- Wheel M. The sprocket-wheel M has three times the diameter of the wheel U', so that the matrix-sheet b moves three times as fast as the paper d. The perforations in the matrix must be larger and separated greater distances than in the punched sheet, and for this reason the sprocket-wheel M is made larger than the sprocket-wheel U'. The matrix-sheet b is held down-ou the slats or plates R by a hinged retaining-bar V above each held in lowered position by a latch V' and 'pin V2. Each retaining-bar Vis provided in its under side with a longitudinal groove W, into which the noses P3 of the valves P can pass after passing through the slots R' and the perforations in the matrix.

A shaft d, having a fiat side d', is mounted to rock over each slat or bar O' in such a manner that it extends over the valves P and slat or plate R, which retaining-bar V can be when turned so that its fiat side is vertical IOO bears down on the valves P and holds them closed. Each shaft d has an arm e, which several arms c are pivoted toa rod f, by means of which all the shafts d together can be adjusted to hold all the valves closed or to permit them to open-when a hole in the matrixsheet b arrives at any valve. The valves must be held closed while the matrix is being introduced and placed upon the slats or plates R.

Whenever a hole in the matrix-sheet h arrives at a valve P, the valve is thrown upward and opened by its spring P2 and the; nose P3 of the valve passes through the hole in the matrix-sheet. The air can thus escape through the corresponding vent-pipe O, permitting the compressed air to force down th-ef piston in the corresponding cylinder G,where f by the corresponding punch E is forced through the sheet a and into its die C below it. As the matrix-sheet h moves forward it` closes the valve P and the piston-rod Gr' isl raised, to be again depressed when a hole arrives at the corresponding valve, and so on.

The mechanism in the valve-chamber Hl may be of any approved construction andy forms no part of this invention.

As the cylinder G cannot be arranged as closely together as the perforations in the sheet a are required, they have been arranged in five groups, in which the severalcylinders l are staggered or offset, so that the punches of any four groups punch between the slots' made by the punches of the remaining group.

Having described my invention, what I claim as new, and desire to secure as Letters?` Patent, is-

1. #In a machine for perfora'ting note-sheets, i the combination with dies and punches and means for guiding paper between them, `of cylinder and piston above each .punch,a valve-3 vchamber for each cylinder, compressed-ain chambers with which the valve-chambers are 2 connected, a vent-pipe connected with each' valve-chamber, a valve for each vent-pipe and means for conducting a matrix-sheet over said valves whereby the same are operated, substantially as herein shown and de-l` scribed.

2. In a machine for'perforati ng note-sheets, the combination with dies and punches, and

means for guiding ,paper between them, of a spring for pressing each punch upward, a rail against which the heads of the punches can rest, a cylinder and piston above each punch, a valve chamber for each cylinder, compressed-air chambers with which the valvechambers are connected, a vent-pipe for each valve-chamber7 a valve for each vent-pipe and means for guiding a matrix-sheet over the vent-valves whereby the same are operated, substantially as herein shown and described.

3. In amachine for perforating note-sheets, the combination with dies and punches, and means for guiding paper between the dies and punches, of a compressed-air-operated mechanism above each punch,- a vent-pipe for each compressed-air-operated mechanism, a valve for `each vent-pipe, which valve has a nose, a plate provided with slot-s for receiving the said noses, means for guiding a matrix-sheet over said plate whereby the valves are operated and .ai retaining-bar for holding the matrix-sheet on the plate, substantially l 'as herein shown and described.
