BEORD-PUNCHING MACHINE.

I To lll whom 'L'tmay concern:

vlBe it known that I, SALVATORE ScooNA- MILLO, a citizen of the YUnited States, resid- Punching-Machines, of which the following is a specification.

This invention relates to a sheet perforating machine for producing musical records adapted to be used in connection with mechanical piano or organ players and devices, and the primary object of the invention is to provide a simple organization of electrically controlled elements which positively and automatically operate to-accurately orv exactly duplicate apreliminarily' prepared record in an expeditious manner Without requiring any special attention on the part of an operator to effect the result sought, and thereby materially reduce the cost of manufacture of .this class of machines and of perforated mechanical records.

The machine` embodying the features of the invention has been particularly devised for producing musical records of the perforated sheet type ordinarily rolled upon spools or anlogous devices -for ready application to a mechanicalpiano or organ player, but it will be understood that the same mechanism may be-used for reproducing any other porforated sheet, such-as that used inconnection with Jacquard looms and in type machines and the like.

The improved machine embodies a gang or plurality of lever punches which .are individually-'operated or are automatically selected in accordance with the openings in the preliminarily prepared record or pattern by the several mechanisms embodied in. the macl1ine. i v

'-The machine also involves means for causing vthe Isheet being-perforated to move in consonance with or at the same rate of speed asthe preliminarily prepared record or pattern, and, furthermore, the variation'in the length or size of vthe openings in the pattern record will beeffectively carried out in the reproduction fsheet by causing the punch, levers automatically selected to operate to have vibrations imparted thereto in order to continuously-cut openings in the reproduction sheet exactly corresponding in length to the openings inthe pattern '.record.

The invention also consists in the construction andv arrangement of they several Speoitlon of Letters Patent.v Application mea my 1o, 1914.- serial No. 850,218.

parts .which will be'4 more4 hereinafter v described in preferred form and subject sto' variations and modifications in the proportions, dimensions'and minor details` without,

departing from theiscope of Vthe invention as outlined in the appended claims.v

In the drawings: Figurefl is a longitudinal vertical sect-lon of al sheet perforating machine embodying the features of theinvention. Fig. 2 is a top plan view,'broken approximately through the center, and also having portions of the perforating. levers removed. Fig. 3 is a transverse vertical section of a portionof, the machine taken in the plane of the line 3 3, Fig. 1, and broken through at the center. Fig. 4 is -a'detail end elevationV showing the driving mechanism for one of the rollers or spools and particularly illustrating the ratchet mechanism for checking backward movement or back lash of the spool or roller. Figs. 5 and 6 show detail views, respectively 1n combined elevation and section, and in cross-section,

showing means forv holding `the end of the paper sheet in separable connection with one of the rollers ors ools. Fig. 7 is adetail perspective view o a portion ofthe cutting means for severing the reproduction sheet from the main body of the sheet after a record has been reproduced or completed. Fig. 8 is a detail sectional elevation of one of the magnets and a portion of lone of the unch levers showing the means for breakmg the circuit of the magnet to permit the lever to vibrate or oscillate to produce an elongated opening in the pattern record.

The numeral 5 designates a frame which I may be ofany dimensions and contour and embodiesI a plurality of parts which will be more particularly hereinafter explained lin specifying the application of the various mechanisms and devices thereto, this frame' having suitable legs 6 for supporting the same at any desired elevation above a ksupport upon which the machine as a `whole may be disposed. At the rear ofthe frameI are uprights or vertical supports 7 that may be suitably tied or braced and having. arms 8 projecting forwardly therefrom and `continuing into :and producing the, opposite sides 9 of a bed or table 10 with the-opposite ends 11 downwardly curved to permit-the reproduction sheet of paper or'other .material to be Y,readily fed thereonto and' therefrom.' vThis bed vor table 10 is also provided with upstanding. side guides' 12* which are engaged Iby the side edges" of the reproducv tion sheet to 'maintain the latter in a positive position relatively to ther punching mechanism which will be presently n explained. At the front and rear extremities of the bed or table 10, suitably flanged

guide rolls

13 and 14 are mounted below the plane of the bed, as shown by Fig. 1, and in suitable bearings 15 of verticalconnecting members 16 of the frame under the bed or table 10 a'sheet feed roll 17 is mounted and will ,be provided with any preferred means to prevent the sheet having loose movement has a transversel extending pocket or chan-` nel 18 near the ront extremity thereof and depending-below thel same, said pocket or channel having an -outlet opening or slot 19 in its bottom. Within this pocket or vchannel 18 female dies 20 are mounted and consist of a plurality of steel plates which are less than half vthe distance between the front and rear walls of the pocket or channel to form. vertical openings 21 therebetween, said openings 21 diverging toward and disposed over the lower outlet opening.

19. It will be understood, therefore, that each die is composed of twoplates22 which have upper slightly convex vedges 23. and

are disposed' in longitudinal aline'mentto form a die4 opening 24, each pair of plates being separated by a steel. partition plate 25 extending the full width of the pocketor channel 18 and coperating with the pairs of plates 22 to complete the several dies 20. The die'openings 24 produced by the plates 22 and 25 are preferably of rectangular form, but it will be understood that this shape may be-varied at will by correspondingly changing the edges of thedies 'around the openings. The diesas composed of the pairs of plates 22 and the plates 25 ar held 1n positive positions in the pocket or chanvnel 18 by rods 26 adapted to be suitably secured at their ends in the side portions of the frames and' readily removable to take out and repair or replace any of the die members. The plates 25 will also have their upper edges slightly convex so as to accurately coincide with the upper edges of the plates 22, and when all of the die 'inembers are assembled and ysecured in the pocket or channel 18 a continuous convex ridge-will be provided'in the bed or table 10 over which the sheet, as at S', from the.

roll 17 is regularlyfed, the said sheet also first passing over

vthe guide roller

14 and 1,17sIs74 then awa from the bed ortable 10 over the guide rol er 13 at the front of the latter.

A iixed fulcrum rod 27 is held between uprights 28 rising, from intermediate portions of the arms 8, and. on this'fulcrum rod an 'insulating bushing 'or sleeve 29 is mounted. Punch levers '30 are suspended from the rod 27 and have intermediate ap.-` ertured enlargements 31k in which the bushing 29 is fitted, there being the same mimber of levers 30 as there are female dies in the pocket or channel 18; and each lever o has a depending punch terminal 32 at its front extremity which is normally held over one of the openings 24 of the dies 20. The levers 30 extend rearwardly from therod 27 and are preferably provided with upturned rear ends 33 to which springs 34 are attached and also secured to a rod or analogous device 35 extendingV across and fastened to the uprights 7 at the rear of the Y the rear portions of the` arms 8, an insulatingbushing 40 being interposed between the lever head. 37 and the rod 39. The head 37 of the lever 38 has an upwardly extendingcontact projection 41 which 'rises slightly above the planes of the upper edges of the arms 8 to coperate with thecontact projection 36 of the rear portion of the lever 30 thereover.

There are as many followers or defining levers 38 used as there are levers 3 0, and the bushing 40 extends fully over the rod 39 and insulates all of the said levers 38. The levers 38 have lower rearwardly projecting contact ends or fingers 42, each lever being provided with a single projection or lfinger, and engaging each lever 38 also is a spring 43 resting against a fiber or insulating block or strip 44 held by a cross-bar 45 secured to the arms 8. The springs 43 operate to maintain the yfollowers or defining levers 38 in a normally yielding position, but the springs 43 are only of such resilient tension as to insure the performance of contact function and'engagement of the fingers 42 with parts disposed for-coperation therewith. The fingers 42 are adapted to engage with metal heads 46 having Shanks 47 held between-insulating strips 48 secured to horizontal supports 49 'extending forwardly from the uprights 7 the Shanks 47 projecting rearwardly beyond the insulating strips 48 any suitable distance to receive electrical ifm-7eme connections The heads 46 have 'front-iconvided by sheet S is being removable frmfthe vportion of the frame which the engage. v .As shown. by ig. 3, -theone f. i pin 55,rand the other. arm vi's-formed with-an Y v-openin the soc .15.y c y ed-.bythel seat 58,' and lthrough which 'outwardly a regular rotation imparted thereto.A roller.51 preliminarily` carriesthe pattern j head 61 engaging a-spring opening 56 and seat 58 of the cap 57 `The spring 62 forces the stud 60 inwardly and the adjacent head of the .roller 51 at the center is provided with a socket 63 to removably receive the stud. The opposite head of the roller 51 has a cylindrical boss 64 with a cross-groove 65 therein 4to fit over the pin 55. 1t will be seen-*that the. roller 51 may beV readily removedby shiftingthe roller longitudinally and pressin until the boss 64 is isengaged from lthe cross-pinf55, andthen the .stud 60 may be released fromthe opposite v-headj-of the roller. It will be understood thatv the bushing 53 with its innerv vfiange 54-rotates in the portion of. the arm in whichit is mounted, and also that.. the stud `60 is `free to rotate. in the annular disk. 59 andthe opening 56 so that the sheet or record, and as heretofore indicated',

the pattern sheet or'record passes over-fthe .is wound upon theflower-rollerr52. v This lower roller 52' is also engaged-andihasdey vices for removing the same lsimilar'yin all:v

It is'obvious that '..the rollers '52 and 69 must-move or rotate at exactly4 the same rate o f speed and the .sheet thereon `as-reproduced `controls the feed of thersaid sheet over the bed or table 1:0, `and .the rate of feed lof this sheetlover the roller 52. To accomplishthis uniformity of movement ofthe

rollers

51 and 69 and also the same rate of movement of the sheet S over the bedy or table 10 as the movement of the pattern sheet S', a power shaft 71 is provided and mounted in suitable bearings 72 at one side vof the machine frame, and on Lthe ends of the shaft 71 are bevel pinions 73 and 74 which respectively mesh with the bevel gears'68 and 70. r1`he bevel pinions 7 3l and 74 are so positioned relatively` to `the bevel gears 68 and 7 O that the rollers 52 and-69xwill rotate'in the same direction or have thesame'windin movement sothat the sheetS as reproduced in accordance with the'pattern provided in the sheet S will be coiled 0n the roller 69 in the same manner as the sheet S is coiled on the roller 52.' On the shaft 71 a sprocket Wheel or other-analogous device 75 is mounted, and

trained thereover is a chain or other belt 76 which extends inwardly and engages `a sprocket Wheel or similar device 77 on a yshaft 78 mounted in suitable bearings 79 and having a friction disk 8O on the end "thereofopposite that to which the sprocket wheel 7 7- is secured. A friction roller 81 is held in continual engagement with the disk 80 and is carried on 'the'inner end of .an

armature shaft 82 of an electric motor y83,

,the Vlatterheing disposed on-a -carrlage or slide' 84 which movablyuengages a pair vof rods 85"extending across the frame and is also provided lwithan adjusting gscrewstem vr86 extendingoutwardly to one side of the .'frameiand provided withwa lbevel pinion 87 meshing with a similarl pinion 88 on the rear endof ari-adjusting r'odorfshaft 89 mounted 81 with respect to `the -disk 80` and thus Vmodify the speed of the shaft 78. and the cutter bar 98 is actuated by a cam roller'c'u', v

- member 100 having trunnions 101 at oppoas may be found necessary duringthe reproduct-ion of any pattern. Positlvely operating means are also provided for lsevering the reproduced sheet after the` latter has been completed in accordance wlth the pattern to be reproduced, said ,severing means consisting of a bracket or frame 92, as shown. in detail by-Fig. 7, embodying a pair o f'- seats for coiled springs 97 which extend out-` wardly and engage the opposite extremities of a sliding cutter bar 98 preferably formed with an inner beveled cutting edge 99'which' coacts with the outer edge of one of the bars 93 in performing its severing function.l 'Iyhe site ends engaging bearings 102 at the outer portions of the heads 95. The cam roller 100 is formed with a cam groove 103 of the contour particularly shown by F ig. 1 and 1nter' secting a shoulder 104 against whlch the outer portion of the cutter bar 98 has bearing so as to insure a' proper rotation of the cam roller 100 in actuatlng the said cutter bar. The cam roller 100 is operated'through' the medium of a handle or gri -nected thereto, and when the sald yroller ismoved inwardly the reproduction sheet S, which is primarily passed between the outer edges of the bars 93 and the inner beveled edge of the cutter bar 98, is forced against the bars 93 and severed and when the cam roller 100 is released the springs 97 force the cutter bar 98 outwardly and at the same time the roller 100 is rotated in a reverse direction until the cutter bar engages the shoulder 104 when the parts of this cutting mechanism will bein normal position. The cutting mechanism as a whole as just'described is secured through the medium of ears or lugsl06 on the ends of the bars 93 to opposite brace members or arms 107 of the frame at a point slightly below the front guide roller 13.

To the upper ends of the uprights 7 above the arms 8 and the punch levers 30 a magnet carrying frame 108 is movably mounted and comprises opposite side bars 109 and a plurality of

cross-bars

1,10, the rear ends of the side bars 109 being fulcrumed or hinged to the upper endsof the uprights 7 and having their front ends detachably secured by screw-bolts or analogous devices 111 inserted therethrough into upstanding supports 112 which are each formed with a` socket 113 having a suitable insulation 114 mounted therein. By removing the screwbolts 111 the frame 108 together with the` supports have electromgnets 116 suspended therefrom, oney magnet from each support. An electromagnet'v is yheld over the upper edge of each punch lever 30 and'has its pole exposed to the upper edge of its correspond-h ing lever. It will be seen that all of the magnets 1.16 are arranged in rear of the fulcrum rod 27 of'the evers 30, and hence when the'rear portion ,of any one of the levers'is drawn upwardly by its magnet the front portion of the same lever will be forced downwardly and the punch extremities ,32 thereof will be caused to punch the sheetl punch extremity andl S fed between the said the die beneath.

` As more vclearly shown by Fig. 8,-the core of the magnet is projected as a whole at the upper end of each magnet, and an armature 1'17 is normally in engagement with the upper end of the core or pole of'eachnmagnet and is carried-by a pivoted or hinged arm 118 extending from the adjacent portion of the cross-bar '110 which 'supports the magnet.

The core 119 of each magnet is also tubular and has an insulation 120 therein which is likewise tubular, and through the tubular insulation a small rod'121 rises from the upper edge of the adjacent lever 30 and extends upwardly to and engages an insulation 1 22 on thek armature 117. The rod 121 may be secured either to the lever 30 or to the insulation 122, and the latter insula-l tion will extend over onl a portion of the armature so as to avoidy interfering with the normal metal contact between the armature 117 and the upper end of the core of the magnet.4 The rod121 coperating with each punch lever 30'constitutes a circuit breaker and will break the circuit of the magnet ting each finger 42 to pass therethroughvand engage its corresponding head. Each lever 30 will continue to punch or vibrate so long as its corresponding follower or defining lever 38 has its finger 42 in engagement with its corresponding head 46, and by this means short and longer openings will be formed in iance with 'they' openin yS. 'WhenV the unper orated portions of the pattern sheet QS" move in between the several ,fingers 42 and thev heads 46, the electrical circuit will be broken' by reason of' the interpositionof a. non-conducting material between'- the'said fingers and'head, and in order to effect anf' elevation of the rear portions vof the levers y it will be understood thatv the magnets 116 ,will 'bel strong enough to overcome any resisting tendency that may beset upbyy the contact projections 36 and 41 and also overcomehe resistance vof the springs 34. Furthermore, care will be taken to so proportionA the upper edges of the levers andthe poles of their corresponding magnets 116 as to insure that each magnet will influence only the lever with which it is intended to coperate and thereby avoid magneticvinterference and the operation of levers that should not be actuated.

VThe' motor'83 Awill be supplied with current from any suitable. line source, and the magnets will be `energized from a battery B held in a suitable inclosure 123 secured to the frame 5. The poles of the battery are connected by `wires v124 and 125 to a .switch 126- inthe manner shown by Fig.

1, and all of. the. Shanks 47 are connected by' a Wire 126 with one` ofthe switch members, the several shanksv 47 having short lengths of wire running therefrom to a .main wire -which will'constitu'te a conductor for all vof the vsh'anks collectively 4relatively to the switch member. The remaining member'of the vswitch 1261is connected by a wire or conductor 127 to the frame 108., and the latter is in turn connected by wires 127 to the armatures 117, it being understood that these armatures will be suitably insulated' will be insulated by the interposition of any suitable insulating means at its pivot or hinge connections relatively to the uprights 7 and as indicated at 130..'

As shown by Fig. 5, the front or receiving roller 69y will be providedV with means for readily .atta-ching the reproduction sheet thereto and for disconnecting said sheet for the purpose of transferring it to another roller. The core of the roller 69 coma been completel and the one end of thereproduction sheet inserted therethrough, and then the heads are turned so as to cause the one tube 132 l to rotate on the other tube 131 and clamp the paper between the tubes and at the same time partially roll the paper around'the core, the rotation yofone tube `011 the other being effected when the ,tubes are pushed inwardly to a distance approximately equal to the width of the sheet, and when the paper has been thus secured, the .roller 69 1s` then connected to -the gear 70- which is arranged in all respects similar to the gear shown inconnection with the roller 52, as shown by Fig. 3,. and hereinbefore explained. After the sheet reproduced has roller 69 or su sequent to the severance of the completed reproduced sheet, vthe heads and tubes of .this roller may ,be readily drawn apart fromthe opposite ends 'of the rolled reproduced sheet and the roller again reset in the machine andhave the extremity wound on'the core of the i of the-sheet S again secured thereto in the same manner for the formation of a further reproduction of the pattern sheet. e

' It will be understoodthatanumber of the rollers 69 may be'supplied with each machine so that no time will'be lost in making a substitution of onev roller for another that has become illed or has the'completed reproduced sheet rolled thereon. 'It will'y also be understood that the same` 'form of roller may be adopted at any other point in the machine where found desirable, as for instance the roller 52 may be similarly con- .structed so as to expedite-the detachment of the rolled pattern sheet therefrom. lFurthermore, each of the rollers may be provided with means for preventing the sheets from running slack thereon and especially the main feed roller 117, and any of the approved devices for this purpose may be .adopted at will. It willl also bel-understood that changes in the proportions, dimensions and minor details may be varied within the scope of the appended claims.
