PERFORATING-MACHINE.

Specification of Letters Patent.

Application filed August 3, 1914. Serial No. 854,621.

To all whom it may concern Be it known that I, HARRY M. SMITH, a citizen of the United States of America, and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Perforating-Machines, of which the following is a specification.

My invention relates to improvements in perforating machines, and has for its object the provision of a machine which is particularly adapted for use in perforating music sheets for use in connection with automatic musical instruments.

The principal object of my invention is to provide a machine by which the perforations in the sheet can be made smaller and arranged closer together, whereby a per forated sheet is obtained which is capable of use in connection with a tracker board having a series of very small openings arranged in close proximity to each other. Thus in connection with automatic organ players in which four separate organs are operated from a single tracker-board, this trackerboard often has as many as 213 openings arranged in one continuous line, and in order that this tracker board may not be of undue length, it'is necessary that these openings be very small and arranged very closely together. Heretofore difficulty has been experienced in obtaining a machine capable of perforating a music sheet to correspond to the openings in such a tracker-board. By my invention, however, I provide an arrangement whereby a sheet can be readily perforated in such a manner. These and other objects of my invention will be more readily and clearly understood by having reference to the accompanying drawings, in which I have illustrated one specific embodiment of my invention, in which Figure 1 represents a plan view embodying the features of my invention. Fig. 2 is a sectional view taken on the line 22 of Fig. 1, looking in the direction of the arrows. Fig. 3 is a sectional view taken on the line 33 of Fig. 2, looking in the direction of'the arrows. Fig.4 is a perspective detail of one of the punch-controlling bars. Fig.

A 5 is a perspective detail of another of the punch-controlling bars. Fig. 6 is an enlarged detail showing the arrangement of the same on the operating shaft.

As illustrated, my invention comprises a suitable support comprising a bed plate 10 and upright supports 11, on which are mounted the various operating parts. The.

15 controlled by the pawl 16 carried by an arm 17 which arm at its opposite end carries the bearing roller 18, adapted to be operated by a cam 19 carried by the main driving shaft 20, which can be driven in any suitable manner. Mounted in the upper portion of the frame is a cylinder 21, over which the pattern sheet 22 is adapted to pass. This cylinder is provided with aseries of circumferential grooves 23, as clearly shown in Fig. 1, and the rotation of this cylinder is controlled by the sprocket wheel 24, controlled by the pawl 25, carried by the operating rod 26. The opposite end of this rod carries a bearing roller 27 which is adapted to be engaged by the cam 28, likewise mounted on the main driving shaft 20. A spring 29, or other suitable means, is provided for counteracting the operation of the cam 28 and for returning the rod 27 to the normal position shown in Fig. 2, after its operation by the cam 28. A holding pawl 30 is likewise provided. The teeth on the two ratchet wheels 15 and 24 are preferably so proportioned that one step of the ratchet wheel 24 moves the patern sheet twice the distance that the sheets 12 are moved by a step of the ratchet wheel 15. Thus, for example, if the pattern sheet 22 ismoved onesixteenth of an inch for each step, the sheets 12 would only be moved about one-thirtysecond of an inch.

The sheets 12 pass over a die plate 31, above which are located a plurality of punches 32 and 32 These punches are arranged in staggered relationship so that there are two series of these punches, the punches of one series being arranged intermediate the punches of the other series. The number of these punches is regulated by the number of perforations it is desired to make in sheets 12. Thus, if these sheets were for use in an automatic organ in which the tracker-board is provided with 213 notes arranged in a single line, there would be 213 of these punchesl07 in one series, and 106 in the other series. These punches pass through openings in suitable guide plates 33 and 34, and are provided at their upper ends with enlarged heads 35. Resting ,portion 37, while the bars which correspond to the series 32 are shown in detail in Fig. 5, and are provided with a cut-out portion 38. The purposes of this construction will be more apparent when the operation of the machine is described.

Aseries of links 39 are pivotally mounted in the bearing plate 40 carried by the frame, there being one of these links for each one of the controlling bars 36, the lower end of each link being provided with a rounded end portion which fits within the corresponding socket in the corresponding controlling bar, thus providing a suitable swinging connection between these two elements; The upper end of each one of. these links is connected in a similar manner to a pattern-controlled pin 41, which pins pass through openings in a suitable guide plate 42 located adjacent to the pattern sheet 22, thus forming a series of operative link mechanisms each consisting of a pin 41 pivotally connected to a link 39which is in turn pivotally connected'to the controlling bar 36,. A spring 43 is provided ffor normally maintaining a tension on the controlling bars in such a direction as to normally maintain a pressure on the pins 41 against the pattern sheet, whereby when an opening. in the pattern sheet is brought opposite a pin 41, the pin is thrust forward through the opening, thus causing the corresponding controlling bar to be thrust longitudinally in the oppositedirection. In order to return these pins to normal position, these pins are provided with a shoulder 44 which is adapted to be engaged by a bar 45 mount ed in a shaft 46, whichshaft is adapted to be rotated by means'of the arm 47 connected to the rod 48, the lower end of which rod is provided with a bearing'roll 49 adapted to be engaged by a cam 50 carried by the operating shaft 20. A spring 51 is provided for normally maintaining the bearing roll 49 in engagement with "the cam surface, whereby when this roller is'engaged with the cam 50 the bar 45 is rotated into the position shown in dotted lines in Fig. 2, and operates to withdraw from the pattern sheet any pins 41 which have been forced through perforations in thesame by means of the pressure exerted by the spring 43.

Tn' order to operate the punches 32, 1 provide a hammer mechanism comprising a hammer rail 52, carried'by a supporting frame 53', the'lower end of which is provided with a cross member 54 adapted to be engaged by one or more hammers 55 mounted on a suitable shaft 56, which hammers are actuated roller 58 adapted to be engaged by the cam 59; 1 preferably provide two of these hammers, one located on each side of the center line of the machine, as clearly shown in Fig. 3, although, of course, any desired number can be employed, but a more even operation is obtained by having two, in the manner shown. With this construction, it will be seen that when the cam 59 strikes the roller 58 that the hammers 55 strike against the cross member 54, and thus forces the hammer rail 52 downward against the tension of the springs 60, which springs operate to return the parts to their normal position, as

soon as the cam 59 passes out of engagement with the roller 58.

Having thus described the construction of my machine, I will now describe the operation of same. The sheets to be perforated are first fed over the guide roller 13, through the guide rollers 14, in the manner shown in the drawings, and the pattern sheet is likewise fed over the cylinder 21. The driving shaft 20. is then operated and the cams carried by this shaft are so timed that the cam 28 first engages with the roller 27 to cause the pattern sheet to'be moved forward one step. ""iThen a pattern sheet is so advanced, if any openings in the same are brought opposite to the pins 41, these pins are forced through these openings into the cylindrical grooves of. the cylinder 21 by means of the pressure exerted by the springs 43. The corresponding controlling bars 36 are thus forced to the left (Fig; 2), and the ends of these'bars advanced to a position beneath the hammer rail 52,, so that they are adapted to be engaged by the same when this hammer is operated. The cam 59 then engages with the roller 57 controlling the hammer mechanism, thus causing the hammer rail 52 to be brought downward, engaging with the controlling bars 3.6 which have been operated in the manner just described. These controllingbars then operate the corresponding punches 32, which punches perforate the sheets 12 to correspond to the perforations in the pattern'sheet 22. It will be noticed that when the controlling bar 36, which corresponds to one of the series'of punches 32, is advanced in this manner to its operative position, that the'J'notch 37 in this bar is brought in alinelnent with the heads of the punches in the series 32 and likewise when the controlling bar36, corresponding to one 3 of the ptinchesin' the series 32, is advanced, the cut-away portion38is'in alinem'ent with the heads of. the punches in the series 32. This construction is necessary on account of the closeness with which the punches 32 are arranged, and on account of the enlarged heads formed o'n these punches in order to permit the'operation by means of the hammer mechanism. If it were not for the cutting away ofthe controlling bars in this manner, one bar would, operate not only its corresponding punch, but would also engage with the heads of the adjacent punches in the other series. This, however, is obviated by this construction in that the heads of the adjacent punches are in alinement with the cut-away portions and thus the controlling bars do not engage with the same. The sheet thus having been perforated, the cam 50 is then brought into a position to engage with the guide rollers 49 which operate the bar 48 to withdraw any of the pins 41 which have been advanced through the openings in the pattern sheet and then the cam 19 engages with the guide roller 18 to operate the ratchet 15 to advance the sheets 12 one step, at which time the machine is in readiness for this operation, just described, to be repeated.

It will thus be seen that I have devised a very efiicient machine in which the punches are arranged in staggered relationship, and likewise the controlling pins which engage the pattern sheet are arranged in such staggered relationship, so that I am able to perforate a sheet with twice as many perforations in a lateral line than has heretofore been the case. Likewise by having the machine so gearecl that the pattern sheet moves through twice the distance as do the sheets to be operated upon, the perforations in the pattern sheet can be'made larger by means of the old form of perforating machine and then this sheet be employed for perforating the smaller openings arranged more closely together on the music sheets.

W'hile I have illustrated and described one particular embodiment of my invention, it will, of course, be understood that I do not wish to be limited to the exact construction shown and described, but that various modifications and changes will readily suggest themselves to those skilled in the art without departing from the spirit of my invention.
