tinuous rate and the beateri striking against the paper a, cooperates with the said rolls to secure the necessary intermittent feed of the paper so that the same may be advanced a definite distance when the punches b are withdrawn, the beater remainlng stationary during the punching action including the insertion and withdrawal of the punches.v
Referring. now 'toithe various constructionalandmechanical parts in greater 'detail, reference number 1 designates the niachine'base which'may be of any convenient form, and is preferably square or nearly'so 1n generaloutline, in order to provide for the convenient arrangen'ient ofthe various parts thereon. 2 designates the source of power, whi'chmay be conveniently supplied by an electric motor as shown; 3 designates the drive shaft driven from the motor 2, and
preferably connectedvtherewith by means of a fie ible coupling 4. This drive shaft is provided with journalbearings 5, 5, on the base plate'l, and carries a friction disk 6:
which is preferably securedto theshaftS at the end thereof, av suitable thrust bearing 6 being arranged to take the thrust of the friction disk 6. The shaft 7 whichis'provided with suitable journals 8, 8, extends preferably atright angles tofltheshaft Ofn this shaft 7 is mounted the movable friction wheel 9 which contacts with the friction disk 6' and n'laybemoved across the face thereof by any, convenient controlling means such as p the elbow lever; 10 provided'with the pin 11 which works in the circumferential slot 12: in
thecoll ar 13 attached to the friction wheel 9 and which may be operated from any convenient point through the link 14 pivotally attachedto the arinlO of the lever 10. such arrangement the speed of the shaft- 7 may be yaried withrespect to the speed of the drivlng shaft 3 at the will of the operarorby adjustingthe friction wheel 9 to contact with any desired portion of theface of 7 i i the friction disk 6. The constantly recipro Gated plate is driven from the shaft"? by means of eccentrics 15 which are received within the circular openings 16in tl1e pit men liTpivotally connected at 18 .to exten sions 1'9 formed on' the plate f for this-rpurposej slugs d are interposed between] the forward edge'of the plate f1 and the penchsjbtssd areplie id d wi h u utnw tions or slots (l1 which normally are opposite the forward edge of the reciprocating plate 7 so that the plate 7 is free to reciprocate therein without striking the slugs d or operating the punches. The slugs d are provided with a longitudinal slot d at the bottom and rest upon a hard? which is pro i 3 bar (i isprovided for'limiting the forward movement of the slugs d, and this bar (Z is preferably seated upon an elastic cushioning means, as for example, the rubber plate 05 interposed between thebar d and its support. The punches b which are preferably circular and are comparatively small'being preferably about 3% of an inch in diameter, are firmly set in thin flat'heads 6 having about the same thickness as the punches b and each of the punches b and heads 6 is guided in contact with the cooperating slugs d by means of the thin plates 20 which are interposed between each of the slugs and punches in the series and are secured to-. gether by means of a transverse rod 21 passing through openings in the plate 20, suitable distance pieces 22 slightly thicker than the slugs and-punch heads 6 being interposed between the adjacent plates 20 in order to hold the plates 20 sufiiciently separated to permit of the free movement of the slugs (Z and punch heads 6 therebetween. The punch plate 0 is provided with a series of perforations 0 for receiving the punches b and is also provided with a plate 0 having an opening 0 which connnunicates with the punchholes 0 and receives the punchings formed during the operation of the machine. the punchings which collect in this opening 0 may be driven out by means of an air blast, suitable connections (not shown) being readily provided for the purpose. 7
Means for positively retracting the p unches are provided and as shown such means comprise a bar 23 connected to the plate fas by being attached to extensions 7? thereof, and the punch heads 6 being provided with a shoulder 6 against whichthe rearward-edge of the plate 23 strikes on its return movement'whenever any of the punches have been advanced by reason of the corresponding .slugd having been raised. The heater 2' is also operated directly, from the shaft 7' and 7 preferably through means connected with the constantly reciprocating plate f. This beateri has preferablythe form of a circular rod or bar extending transversely across the machine-beneath the punch plate 0 and mounted upon the longer arms 24', 24 of two elbow levers 24, 24, one at each end thereof; The'bars 25, 25 arepivotally connected to the shorter arms 24L, 24 of the elbow levers 24, 24: as shown at 26 and at their opposite ends are provided with a slot 27 which receives the pin 28 which is secured .to the plate fby any convenient means which will provide for its adjustment thereon, the connection illustrated for this purpose being shown in detail in Figs. l and 5 and comprising a plate 29 slotted at 30 to fit over the rear edge of the plate to which it may be clamped as by means of the cap screw 31 passing through an enlarged opening 32 formed in the plate f and the adjustment of the plate 29 carrying the pin 28 with respect to the plate 7 being secured by means of a set screw 33, which. passes through a threaded opening 3i in the plate 29 and contacts with the edge oftheplate 7 and which may be locked in adjusted position by means of the lock nut 35. The lost motion created by the provision of the slot 27 in the bar 25 provides for the withdrawal of the punches 5 before the beater is operated to advance the paper as is clearly shown in Fig. 3. The paper feeding roll it in the construction shown is also driven from the shaft 7, the gearing for this purpose comprising a worm 36 on. the shaft 7, and a worm wheel 37 which coacts with the worm 36 and is secured to the shaft 38 placed preferably paral lel toand on the opposite side of theframe 1 from the shaft 3, and the roll it is driven therefrom by means of miter gears 39 and d0. The roll h drives the rolls g 9 held firmly in contact therewith by springs 41 and 42, by friction, the paper a passing between the roll hand the rolls g g and being firmly held by such frictional contact. The paper a is fed from a roll, being preferably delivered to the machine over rollers 4-3, 43*, between the rolls 4:4: and 45, the rolls 45 being provided with rotary lmives 46, L6 at each edge thereof for trimming the edges of the paper, over and across the punch plate 0, beneath the beater 11, around the upperroll g and betweenthe roll in and the lower roll 9 whence it is delivered over the delivery plate 46.
For aid in holding the paper stationary during the punching action, I provide a bar 7 which is spring mounted upon the return plate 23 and has a spring contact with the face of the punch plate 0 during the time that the plate 7 and the return plate are advanced and while the punches which are being operated are within the paper. This plate is, of course, withdrawn from contact with the punch plate 0 as soon as the'punches are withdrawn from the paper so that it does not prevent the advance of the paper in the machine at the proper moment.
The apparatus described operates as fol lows:
"Power being supplied as by passing an electrical current through the 'motor 2,the shaft 3 rotates, thus rotating the friction disk '6' and the frictionwheel 9 'and'iinparting rotation to the shaft 7 which speed of rotation may be varied by adjusting the friction wheel 9 in its various positions. Thepaper a ispassed overthe feed'rollers 43, 43 and over the trimming'rolls l 45 by which itsedges aretrinnned to the proper width, over and across the punch plate '0, beneath'the beater i, around the rollers f and h and between 'the'roll k and the roll 9 1 and the roll it being rotated from the shaft 7 by meansof the worm 36, worm wheel 37, shaft 38 and bevelgears 39 and 40, pulls'the paper forward atthe desired speed which is regulated-by means'of the friction wheel 9. The oscillatingplate f is continuously oscillated from the shaft Tand so long as all the slugs d remain in their lowermost or depressed position, the paper passes through'the machine without any perforations'being made therein. As soon, however, as any one or more of the slugsd are ele vated, as may be done by means of the keys of the piano or by the pneumatics of the player machine,'or manually or in any desired way, the opening al beingnolonger opposite the plate f, the plate 7 strikes against the slug (Z andthepunch-b actuated thereby punches a holethrough the paper.; As the plate 7 is \Vl'C-hdliLWIl the plate 23 which is secured thereto is WltlidIfLWHtllEIewith, thus withdrawingthe punches b from contact with'the paper and as soon as the punches b'have'passed outof the paper and the pin 28 has come into contact with the bar 25 at the end of the-slot 27,- it actuates the beater '11, and the paper, bymeans of the conjoint action of the beater 2' and the rolls lug and 9 is advanced thenecessaryspace for receiving the succeeding perforation, which space is preferably'slightly more than the diameter of'the punch openingsso' that successive circular openings-situated close together will i be punched 3 into the' material of'the paper so long as a slug 'clisraised. The provision of the slot-2T inthe'bar 25 makes'it possibleforthe beaterz" to be raised by the pull of the paper so thatgwhile the rolls 7t,g and g are op'erated to feed the paper forward continuously, thepaper is not advanced at the'punching point during the punching operationandithe tension upon the paper serves to elevate the beater which ismechanically depressed in the manner described-as soon as the punching operation has'been completed.
have referred toinyimprovedmachine lie'reina'bove more especially as operating upon a single sheet-of paper It will-be understood, 'ho\vever,jthat its usefulness is not limited 'tothe perforation of a single sheet of'paper at'a time, as woul'dojrdinarily be practised in the original "recording of a i composition, but that-a number ofsheets may be superimposed upon one another and passed tllFOHglltllG inachine' together, and the machine may be used in this manner more especially for-the purpose of inaking a number of ClIlPllCZL CGS fI'OIH a sheet already recorded, the slugs (Z being preferably oper ated for, such purpose by pneumatic means as'in theordinaryplayer-piano. i
While I have illustrated an d described a specific embodiment of my invention, in order that the same'inay be clearly understood, it is to be recognized that the saine is for the purpose of illustration only and that my inventionis not confined thereto, but is as broad as my claims, and that merous departures maybe made from the specific construction shown-within the scope ofmy "invention 'WltllOUt departing from; my invention or sacrificing any 0f its-advantages. 1 r i Having thus described 'my' inventioinwhat I clainiis: v
