MACHINE FOR MAKING PERFORATED MUSIC.

Specification of Letters Patent. Patented Mar, 26, 1912,

Application filed July 3, 1909, Serial No. 505,937. Renewed August 10, 1911. Serial No. 643,401.

To all whom it may concern:

Be it known that I, EDGAR WILLIAM MY- nns, a citizen of the United States of America, and a resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Machines for Making Perforated Music, of which the following is a specification.

My invention has particular reference to machines for making perforated music, particularly of the type illustrated in my application Serial- No. 482,615, filed March 10th 1909, and has for its primary object to provide means for effecting a positive return of the punches to their normal or inoperative position.

A further object resides in the provision of means of novel construction for yieldingly pressing the keys toward the actuator or hammer.

Further my invention resides in providing means for yieldingly supporting said punches.

Referring to the accompanying drawings, illustrating a preferred embodiment of my invention: Figure 1 is a rear end elevation of my improved machine, parts being broken away. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a fragmentary sectional view, on enlarged scale, illustrating more particularly the construction of the die, one of the punches with its attendant controlling means, and the punch retracting means. Fig. 1 is a similar view illustrating the punch as having been operated by the actuator or hammer. Fig. 5 is a fragmentary detail view illustrating more particularly the arrangement of the ad justable keys for the punches and the manner of sliolably supporting the same, and Fig. 6 is a fragmentary view of the punch retracting 'means.

Referring to the drawings by numerals of reference, 1 indicates a frame having journaled thereon shafts carrying feed rollers 2 and 3 for the pattern or master-sheet 4 and the copy sheet 5 respectively, as clearly shown in Fig. 2, which feed rollers are provided with pawl and ratchet mechanisms, to be described, connected for simultaneous operation, whereby said feed rollers can be operated together, in an intermittent manner to impart a step by step movement to sa1d master and copy sheets. These ratchet devices comprise ratchet wheels 6, fixed to the shafts of feed rollers2 and3 (see Fig. 1), and spring pressed pawls 7 for engagement therewith, which pawls are pivotally supported on suitable carriers 8, swingingly mounted on the shafts of said feed rollers. Carriers 8 are connected by a link 9, and the lower thereof, which is in the form of a bell crank lever, has one of its arms pivotally connected to a pitman 10 which latter is provided on its upper end portion with a strap engaged about an eccentric 11, provided on a drive shaft 12, having a pulley 13 to which power is applied, as by a, belt, not shown.

Associated with feed rollers 2 and 3are suitable presser rollers 14, journaled in slidably supported blocks 15 which are yieldingly pressed, as by springs 16 toward their respective feed rollers, as clearly shown in Fig. 2.

Reference numeral 17 indicates a die plate removably arranged on a base 18, extending transversely of frame 1 at the forward end thereof, see Figs. 1 and 2, and provided with a row of die openings corresponding in number and location to a series of vertically movable punches 19, slidably supported in a transverse member 20 of frame 1, spaced above die plate 17 so that the copy sheet 5 can be moved therebetween. Springs, as 21, yieldingly support the punches in an elevated position. Punches 19 are provided on their upper end portions with elongated heads 22, having lips 22 on their forward end portions which engage under suitable stops 23 and thereby limit upward movement of the punches. Heads 22 are held between vertical guides 24, in the form of ribs or walls formed on the upper face of frame member 20, directly beneath a single actuator or hammer 25 supported for vertical sliding in suitable guide grooves, as 26, of frame 1. This actuator or hammer 25 is operated by a pair of vertically reciprocating pitmen 27, driven by a pair of eccentrics 28 on the drive shaft 12, as will be more fully described hereinafter. Heads 22 are disposed below the path of movement of the actuator or hammer 25, and therefore in order to operate the same, an intermediate pressedtoward the path of movement of the actuator or hammer 25, by pressers 30, supported for sliding in openings or ways provided in a transverse frame member 30.

A These pressers 30 comprise stems slidably engaged in plugs 30*, and heads 30 which bear against the rear faces of said keys. Encircling the stems of these pressers 30 are springs 30 the same bearing against the heads 30 and the plugs 30 which latter are threaded in the rear end portions of the openings or ways of frame member 30',

whereby they can be adjusted, as desired to regulate the tension of said springs.

In connection -with keys 29, I provide selectors 32, there being one for each key, which selectors are pivoted, as at 33, to suitable extensions of frame 1 and provided on their lower end portions with pivotally supported fingers 34, confined between a spring 35 and set screw 36 of the selectors, whereby a desired adjustment of said fingers on the selectors can be'obtained. These fingers normally engage keys 29 and prevent sliding thereof and by reason of pressers 3O tending to slide said keys, said selectors are held under tension, thereby insuring of their trackers 37, consisting of rollers journaled on their upper end portions, being firmly held against the master sheet. Upon a tracker 37 of a selector entering an opening of the master-sheet, as indicated in Fig. 3, the key controlled thereby, being relieved of its restraining influence, is moved by its presser 30 into the path of the actuator or hammer 25. In Fig. 4 I have illustrated said actuator or hammer in lowered position,-and those of the keys 29 as have been set by their selectors in the manner just described, engaged thereby and having operated their punches 19 to perforate the copy sheet 5.

The means provided on keys 29 for engagement with fingers 34,- as now considered, comprises horizontally disposed pins 38 arranged in suitable cut outs, as shown, provided in the rear end portions of said keys. Fingers 34 have their lower end portions formed with cam surfaces 34, provided for engagement with the pins 38, to insure of proper engagement of the selectors with their keys upon each return movement of the punches.

To prevent keys 29 slipping when en- I gaged by the actuator or hammer 25, I form the same with inwardly tapering seats, as 29 adapted to receive the active end por' tion of said actuator or hammer, which is preferably reduced to correspond thereto in cross sectional form.

Reference numerals 39 and 40 indicate spools provided for the pattern or mastersheet 4, which unwinds from the former and after passing over a bearing roller 41 and feed roller 2, is taken up on the latter. Selectors '32 are arranged in front of bearing roller 41, so that the latter provides a firm support for the pattern or master-sheet at the point where it is engaged by the engaging or tracker members of the said selectors, as clearly shown in Figs. 2 to 4 inclusive. Copy sheet 5 being fed across die plate 17 is passed between feed roller 3 and its presser roller 14 and made fast to a suitable take up spool 42. Take up spools 40 and 42 are driven by belts, as 43, 43 respectively, passing over suitable sheaves 44 and 45, the former of which is fixed to drive shaft 12 and the latter to the shafts of said take-up spools. These belts are preferably formed of coil springs, such elastic construction permitting of .their' slipping on the sheaves 44, 45 after spools 40 and 42 have been rotated to take up such of the master and copy sheets as have been advanced by the feed-rollers.

Reference numeral 51 indicates a retractor for the punches 19, the same being connected by a screw 52 for movement with the actuator or hammer 25 and being provided at its lower end portion with a plurality of fingers 53, there being one for each punch, which project under the forward end p0rtions of the heads 22. Retractor 51 and actuator or hammer 25 are directly connected by said screw 52 to a head 54, pivoted as at 27 to pitmen 27, which screw passes through slots as shown, provided in the retractor and head, and being threaded in the actuator or hammer, whereby both the retractor and the actuator or hammer can be adjusted with respect to one another on said head. Set screws 55, provided in head 54 and bearing on the upper edge of the actuator or hammer 25, assist screw 52 in holding said actuator or hammer as adjusted.

In operation, drive shaft 12 is driven continuously thereby causing retractor 51 and actuator or hammer 25, which latter is common to all of the keys 29, to have constant movement. During this continuous movement of shaft 12, pitman 10 swings carriers 8 to operate feed rollers 2 and 3, as described, thereby imparting a step by step movement to the master and copy sheets 4 and 5 respectively. This step by step movement of the master sheet is so timed rela tively to the actuator or hammer 25, that an interval of time, suflicient to insure of the shifting of the keys 29 by such of the selectors as have their engaging or tracker members engaged in openings of the master sheet when the latter stops, elapses prior to the active stroke of said actuator or hammer. The next unit of feed of pattern or master-sheet 4 occurs after retractor 51 has elevated those punches operated to perforate copy sheet 5, those engaging or tracker mem bers 37 which are engaged in openings of the pattern or master-sheet, riding or being forced therefrom during such movement of the pattern or master-sheet and thereby returning their keys to their inactive position. To facilitate the operation of threading the sheets between feed rollers 2 and 3 and their companion presser rollers 14, I have provided novel means for simultaneously shifting said presser rollers therefrom, said means comprising a shaft &6, journaled on frame 1 and provided on each end portion with a pair of fixed arms, as 47, arranged to engage pins or engaging parts 4L8 on the slidably supported bearing blocks 15. A suit-able handle is provided on shaft 46 for rotating the same and thereby causing arms 47 to slide bearing blocks 15 in which the presser rollers are journaled. Springs 16, as will be readily understood, return bearing blocks 15 to their normal positions. In obtaining a positive return of those punches operated to perforate the copy sheet, all danger of mutilation of said sheet, as by sticking of the punches, is avoided.

My improved key pressers are of simple construction, can be readily positioned in the machine, and the tension of their springs easily regulated.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent of the United States of America, is:

1. In a machine for making perforated music, a punch supported for movement, a drive shaft, a head supported for movement toward and from said punch, a driving connection between said shaft and said head, an actuator for said punch adjustably supported on said head, adjustable means for holding said actuator in adjusted position, and a retracting means supported on said head for adjustment independent of said actuator.

2.
