MACHINE FOR PIERCING THE SOUND-PAPER 0F PIANO-PLAYERS.

Specification of Letters Patent. Patented J n; 12 1915.

Application filed January 31, 1914. Serial N"... 815,686.

To all whom it may concern:

Be it known that we, JOHN MEsNY TOUR- TEL and ViLLnRoY CORNEY DOUBLEDAY, citi- Zens of the United Kingdom of Great Britain and Ireland, and residents of 52 Eaton Rise, Ealing, London, England, and

37 VValbrook, London, England, respec-- tively, having invented certain new and useful Improvements in a Machine for Piercing the Sound-Paper of Piano-Players and the like, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a hand-operated machine for perforating the sound paper or music rolls used on piano players and similar musical instruments. Hitherto machines of the kind have been provided with a large number of piercing devices having a separate punch for each note. This large number of punches involves complicated construction and consequent expense. In other forms of machines the punch and the die, or the punches and the dies where a plurality are employed, have been so connected that they may be displaced together with relation to the paper roll. Such an arrangement necessitates a machine of considerable size.

The machine according to our invention is provided with a single punch adapted to slide on a preferably removable bridge or the like, a fixed die plate having a plurality of perforations adapted to receive the punch (a separate perforation being provided for each note), a rack on said bridge for the purpose of engaging the punch and securing its correct positioning with relation to the per forations of said die plate, and a plurality of removable scales each arranged for a particular musical key so that sharps and flats not indicated in the music, because inherent to the key, are easily located.

Any convenient or known arrangements may be employed for indicating the correct position of the perforations such as for instance the employment of suitable pointers on the machine or the provision of suitable markings on the tune sheet.

In the accompanying drawings, Figure 1 is a front elevation partly in section of a machine according to this invention. Fig. 2 is a plan view of a machine similar to that shown in Fig. 1. Fig. 3 is a cross section through a machine with a cover. Figs. 4: and 5 are two views of the punching device.

Fig. 6represents two of the key scales used for locating the positions of the notes.

The machine shown is mounted upon a base 1 fitted with a cover 2 and comprises brackets 3 and 4 on which are mounted the rollers 5 and 6 both of which can be turned by hand wheels 7 and 8, overturning being prevented by the double end spring 9 which has friction pads 10 pressing against the inner face of each hand wheel.

The roll 11 is first wound on roller 6 and has its free end attached to pin 12 on roller 5 in such a manner that the rotation of roller 5 will draw the paper from the roller 6 over the rest 13 in which are perforations 1d, the said rest acting as a multiple die for the punch. Above the rest 13 is a bridge 15 carrying a rack 16. The punching device travels on this bridge and comprises a carriage 1'7 furnished with grooved rollers 18. In this carriage is fitted a punch 19 con trolled by spring 19 and adapted to be depressed against the spring by the camshaped lever 20 pivoted on the carriage at 21. The carriage can be moved to and fro on the bridge by the side handle 22 and is furnished with a ball 23 controlled by spring Qff, said ball engaging with the rack 16. It is thus seen that yielding means are provided to stop the carriage at the proper position,

upon the same being moved into proximity punch is a side pin 25 attached to the punch to move vertically with, it and adapted to enter the spaces between the teeth for the purpose of insuring the correct positioning of the punch above one of theholes 14 in the rest 13. This correct positioning is assisted by the action of the said ball 23 on the front of the teeth of the rack16, said teeth being preferably rounded to prev'ent the ball resting on a single tooth and insure itstaking a position between two teeth. The bridge 15 has projections 26 which enter slots in the brackets 3 and 1 and are held therein by pivoted catches 27, thus permitting the bridge to be readily removed. I

The rollers are supported at one end by spindles 7 and 8 secured to the hand wheels 7 and 8 respectively and adapted to rotate in bushes 28 and 29, said spindles having suitable recesses to receive the keyed ends of the rollers, which are supported at their opposite ends by spring bearings 30, 31, which keep the rollers pressed up to the spindles 7 and 8*. To insure the correct positioning of the paper the rollers can be shifted longitudinally by adjusting the said bushes which are shown screwed into the bracket 4 and which can be fixed when adjusted by a set screw.

To dismount the rollers it is only necessary to push them back against their spring bearings sufficiently to release the keyed ends from their spindles. The sound paper is shown with transverse lines alternately thick and thin with intermediate graduated markings, and the rest 13 has pointers 82 to which the required line or graduated mark is brought to insure the correct longitudinal positions ofthe perforations. The value of a note depends upon the distance between it and the following note, and this distance is determined by which line or mark is next brought opposite the pointers 32. To produce a sustained note a continuous perforation is required, and this is obtained by moving the paper from one line or mark to the next mark or line and punching at each setting, the perforations overlapping and forming a slot. I

The two scales shown in Fig. 6 represent the keys of C major and D flat major. In the former of these the notes appearing on the scale are the natural or white notes of the piano, while in the other scale the fiattened notes are correctly positioned for the six fiats represented in the key: it is, therefore, unnecessary to bear in mind whether a note is flattened or not because if the pointer on the carriage is brought opposite any of the notes on the scale it will punch them correctly as natural or as fiat notes. The positions of accidental notes appearing in the music are readily identified by the dotted and note lines shown on each scale: a flattened note requiring that the pointer 35 in the punching carriage shall be brought opposite the adjacent line to the left of the note shown on the scale and a sharpened note the same amount to the right.

The scales are provided with holes 34 near each end adapted to fit over the rest pins 33 on the brackets 3 and 4; the scale is thus held close to the pointer 35 in the punch carriage, as shown by line and dot in Fig. 2.

What we claim and desire to secure by Letters Patent is 1. In a machine for perforating tune sheets a plurality of rollers to engage the tune sheet and effect the travel of the same, a bridge arranged between the rollers and extending longitudinally thereof, a toothed rack secured to the bridge with its teeth extending upwardly, a carriage to travel longitudinally upon the bridge, a substantially vertically movable punch connected with the carriage, means to move the punch downwardly, a pin carried by the punch to enter a selected space between the teeth of the rack upon the downward movement of the punch to lock the carriage against movement, and a perforated rest arranged between the rollers to cooperate with the punch.

2. A machine for perforating music rolls having two rollers, a perforated rest between the rollers, a movable bridge above the rest, a toothed rack alongside the bridge, a punching device capable of movement on the bridge and comprising a spring-controlled punch capaole of depression by a lever, rollers to facilitate movement of the device on the bridge. a handle by which the device can be moved, and a projection on the punch adapted to enter a space be tween two teeth when the punch is depressed.

3. In a machine for perforating tune sheets, a plurality of rollers to engage the tune sheet and effect its travel, a bridge extending longitudinally of the rollers, a toothed rack secured to the bridge with its teeth extending upwardly, a carriage to travel longitudinally upon the bridge, a substantially vertically movable punch connected with the carriage, yielding means con nected with the carriage and engaging the sides of the teeth of the rack to stop the carriage in the proper position, and separate means automatically moved into engagement with the teeth upon the downward movement of the punch to lock the carriage against movement.

4. In a machine for perforating tune sheets, a plurality of rollers to engage the tune sheet and eflect its travel, a bridge extending longitudinally of the rollers, a carriage to travel longitudinally upon the bridge, a substantially vertical movable punch connected with the carriage, yielding means to stop the carriage at the proper position when moved into proximity there to, and separate means to positively lock the carriage against movement upon the down stroke of the punch.

In witness whereof we have hereunto set our hands in presence of two witnesses.
