Patented Aug. 1c, 1932 UNITED STATES PATENT OFFICE LOUIS FRED HAGEMANN, OF NIAGARA FALLS, NEW YORK, ASSIGNOR TO AMERICAN SALES BOOK COMPANY, LIMITED, IIORON'IO, ONTARIO, CANADA, A CORPORATION OF- ONTARIO, CANADA MANH'OLD RECORD MACHINE Application iiled September 90, 1987. Serial No. 220,664.

This invention relates to machines for "making manifold records, and ,in respect to dressing machines, autographic registers and the like Among the ob ects of the invention are A practical arrangement of the control parts of the machine for convenient manipulation by the operator; the provision of practical and eflicient strip feeding mechanism; the provision of associated motor driven feed mechanism and motor controlling devices, which lend themselves to ready and eflicient control operation by the operator; the provision of practical carbon sheet supply and control devices, which are eflicient in operation and are adapted for manifolding a large number of superposed record strips without renewal.

Other objects of the invention will be in part obvious and will in part appear hereinafter.

The invention accordingly comprises the features of'construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which- Fig. 1 is a perspective view of the upper part of conventional type of manifolding ma chine equipped with the invention;

2 is a side elevation of a portion of the right hand end of the machine of Fig. 1, certain parts being in section or broken away for the purpose 0 clearer disclosure;

3 is a cross-section of Fig. 2 on the line A- Fig. 4 is a cross-section through the shaft of the strip feeding mechanism; and

Fig. 5 is a perspective detail of one of the carbon sheet rolls and its mounting, partly in section.

Referring now more specifically to the drawings, the numeral 1 indicates the upper portion of the frameof a fiat platen type of manifoldin machine such, for instance, as the Elliottisher billing machine. In practice this frame is customarily supported on legs (not shown). The numeral 2 indicates the flat laten of such machine, the platen being shi table up and down by the control member or foot pedal 3, as usual in such machines, the upward shift of the platen being accomplished by a spring. When the platen is in its upper position the record strips 4 lie s read out'thereon and are gripped between t e upper face ofthe platen and an overlying cross plate as 5. It will be understood that a downwardly striking ty ewriter is supported on the frame for bein shifted back and forth and from side to side, so that typing may be effected on different portions of the uppermost record strip lying above the platen.

At the right hand end of Fig. 1 the record strip feed mechanism is disposed. In the present embodiment, this feed mechanism is motor driven through a driving gear 6 which is a worm gear. The gear 6 is driven by worm 7, in turn driven by the electric motor 8 through a flexible shaft 9, the motor being supported upon a bracket 10 at the side of the machine. The electric circuit through the motor includes the conductors 11 and 12, the conductor ll-coming from an electric generator 13, and the conductor 12 leading to electric contact 14. The numeral 15 indicates another electrical contact coming from the other side of the generator 13 through condue-tor 16. It will be understood that the circuit through the motor is made and broken by relative movement of the contacts 14 and 15 into or out of contact with each other, making of the circuit causing the motor to be energized and thereby to drive the gear 6 through the shaft 9.

In the present embodiment, the carbon sheets are mounted at the left hand side of the machine (Fig. 1) and extend from carbon sheet supply mechanism onto the platen 2, the carbon sheets being interleaved with the record strips on the platen so as to transfer to lower record strips type impressions made on the uppermost record strip. The numerals 17 and 18 indicate carbon roll carriers or plates, supported and reciprocally translatably movable on the upper edges 19 of laterally'projecting members of the frame 1. The plates 17 and 18 have forwardly inclined, downwardly extending slots 20, these slots being opposite each other in pairs, as illustrated. Each carbon sheet extends onto the platen from a rotatable supply roll 21 (Fig. 5%), being coiled on a core or sleeve 22 rotata le with a squared shaft 23 which passes through said sleeve. The ends of the shaft are reduced to provide journals which may be inserted and removed from slots 20. C01- lars 24 are pinned to the shafts 23 to restrain endwise movement of the shafts. At one end the journal of each shaft extends outside the adjacent carrier plate 18 and has keyed thereto a ratchet wheel 25 (Fig. 5), the outer end of the journal having a handle 26. The unmeral 27 indicates a pawl which is movable at will to and from position restraining rotation of the ratchet 25 in a direction to deliver carbon sheet from the supply roll 21. The pawl 27 has a handle 28, and whengnoved to one side the shaft 23 may freely rotate in a carbon sheet delivery direction and in strip feeding direction. There may be as many supply rolls 21 and shafts 23 as needed, a plurality being illustrated in the present embodiment. The plates 17 and 18 are retained on the edges 19 by keeper brackets 29 screwed to the inside faces of the frame pieces 1, and said plates are braced apart by the brace bars 30 which latter are 1n turn braced by the stiff members 31.

For shifting the carbon supply carrier in either of opposite directions, there is provided a member or bar 32 (Fig; 1) having gear teeth 33, and forming a rack in engagement with the pinion 34, which pinion is fixed on shaft 35 j ournalled in the frame 1 beneath the carbon supply carrier, the shaft 35 having a handle 36 for conveniently rotating the same. Outwardly projecting from the plate 18 are the headed rack supporting and guiding pins 37 which pass through slots 38 in the rack bars. Upwardly projecting from and fixed to the rack bars, are the pins 39, which pins in a certain position of the rack bar act as pawls to -prevent rotation of the carbon sheet supply rolls in a strip feeding direction.

On the frame member 1 is a rotatable shaft 40 havin a control handle 41 and having latch mem ers 42, the members 42 being forked at 43 and adapted to engage overthe brace bar 30 of the carbon sheet carrier. In

the position shown in Fi 1 the latch bars are in engagement with the race bars 30 and restrain the carbon sheet carrier both from forward and rearward movement. In practice, the face of one of the forks 43 may have an incline such that when the carrier is strongly urged to the right, the latch 42 will be thrust from engagement with bar 30 and permit advance movement of the carrier.

In the present embodiment of the invention, the feed of the record strips is effected, in greater part, by upper and lower feed rolls between which the superposed strips are frictionally ripped for being fed. The numeral 44 indicates a bracket secured to the frame of the machine and havin upstandin fixed plates 45 and 46. The Tower feed r0 1 is composed of the two trucks, or cylindrical members or discs 47, which are alike and are keyed to a feed roll shaft 48 journalled in the plates 45 and 46, said shaft having a handle or knob 49 for manually rotating the same. Each truck 47 has a peripheral notch or recess 50, these notches being in alignment longitudinally of the axis of rotation and adapted to relieve the friction grip on the stri s. Keyed to the roll shaft 48 at one side of the plate 46 is a gear 51 in mesh with a smaller gear 52 on the upper feed roll 53, this latter roll being of reduced diameter at each of the points 52 coincident with the rotarypath ofcertain strip aligning pins hereinafter described. The ends of the upper feed roll 53 are reduced and pass through slots in the upward extensions 54 of -the plates 45 and 46, and are journalled at the lower ends in links 55 disposed at the outside of the extensions 54. In the upper end of the extensions 54 is journalled a manually operable gri relieving shaft 56, having an eccentrically disposed wrist pin 57 journalled in the u per end of the link 55. Thus when the sha 56 is turned, as by its handle 58, the upper feed roll 53 is raised or lowered and thereby adapted to relieve the grip on the record strips passing therebetween. The numeral 59 (Fi 4) indicates a spring which operates on t e upper feed roll shaft to urge it toward the lower feed while the record stri s are held. The arm 4 60 may coo rate for t e purpose with a fixed plate 61 w pose of bracing the lates 45 and 46 in p ace.

In the present-embodiment, the. aper'record strips 4 come from a zigzag fol ed packet of such strips ass-indicated dia ammatically at62 .(Fig. 1). Each of the strips 4 will have 'ch latter may also serve the ura longitudinal series of printed forms (not shown) and also a series of form re 'stering apertures 63 the apertures alternating with the printed 'orms and providing a duplicate longitudinal series of apertures, although a single series at the center of the strip would answer some purposes. From the sup ly packet 62 the record strips are threa ed around the carbon supporting rollers, or shafts 23, and may lie directly against the respective carbon rolls 21. Thence the strips pass to and across the platen 2 to the grip of the feed rolls 47 and 53. The carbon sheets coming from the rolls 21 will lie between the record strips and above the platen 2 but, in the present embodiment, the carbon sheets will not be extended to the feed rolls when typewriting is being done. On the inner side of each of the trucks 47 are thin metal disks 64 fixed to the feed roll shaft 48 to rotate synchronously with the trucks 47. To each of the disks 64 is ivoted a record strip ali ing pin 65 (Fig. 4 the pivot of said pin ing indicated at 66. The aligning pins 65 are thus rotatablewith the trucks 47 and are reciprocally movable on the axes 66 trans versely of the feed roll, being pressed outwardly of the feed roll by the spring 67.

At the Opposite side of the thin disks 64 from the trucks 47, are the stationary members or disks 68 fixed to the stationary brace rods 69. The disks 68 are annular and the inner contour of each provides a cam. The aligning pin 65 has a cam follower pin 70 passing through a slot inthe disk 64, rotation of the pins with the feed roll causing the cam follower 70 to contact with the cam periphery of the annular disk 68, said cam being of such shape as to cause retraction of the aligning pin at a certain position in the rotative movement of the feed roll and extension of the aligning pin at another rotative (position, the aligning pin being held retracte greater part of rotation of the feed roll. The

'reduced portions 52 of the upper feed roll accommodate passage of the allgning pins 65 when the latter are in extended position.

When the control member or pedal $3 is in its upper or idle position the switch members 14 and 15 are out of contact so that the circuit is broken and no current is being expended. By lowerin the control member 3 the circuit will be ma e and the gear 6 caused to rotate. For the purpose of actuating and controlling rotation of the'feed roll, the inner face of the hub of the gear 6is provided with a recess 71, one end of which provides a shoulder 72 adapted to serve as a clutch element. Outside the plate 46, the shaft 48 has a collar 73 securely pinned thereto (Fig. 2), and having a recess into whicha clutch element, or clutch dog 74 may be received, there being a spring 75 tending to urge the clutch element 74 outwardly toward the inner face of the hub of the gear 6 and into cooperative for the.

relation with the clutch element 72 when in registry with the recess 71. The clutch element 74 lies closel alongside the (periphery of the shaft 48 an has an incline shoulder or cam nose 76 which is adapted to contact with a clutch shifter 77, and be moved from clutch enga ement with the shoulder 72.0f the gear 6. The clutch shifter 77 is comprised in a rod guided in brackets 78 and 79, a spring 80 being disposed to thrust this red to clutch shifting position. The upper end of the clutch shifting rod has an inclined cam tooth or nose 81 with which the nose 76 of the clutch element 74 comes into contact at a certain point in rotation of the shaft 48, with the result that the shifter tooth 81 quickly trips, or cams, the nose 76 to the left (Fig. 2) and draws the clutch dog 74 out of engagement with the shoulder 72 in the gear 6, thus disconnecting the feed roll from driving operation of the gear 6,it being understood that the gear 6 is journaled upon the shaft 48 so as to be adapted to rotate thereon without rotating such shaft unless the clutch elements are in engagement. For moving the clutch shifter 77 out of clutch shifting position, it is provided with a lug or tooth 82 to be engaged by a counterpart tooth 83 of a clutch shifter operator and detainer .member 84, urged toward the tooth 82 by a spring 85. The detainer 84 is pivoted to an upstanding slide rod 86, the lower end of which rod is pivoted to one end of a lever 87 fulcrumed eneath the platen as at 88 (Fig. 1) said lever being connected with the foot pedal 3 by the link 89. The arrangement is such that when the foot pedal is in its upper position, the lever 87 and the detainer 84 are likewise up, and the members 14 and 15 out of contact. When the lever 3 is depressed the detainer member 84 will be drawn down, and if at that time the tooth 83 operatively registers with the tooth 82 of the clutch shifter, the clutch shifter will likewise be drawn down so that its nose 81 will be out of the path of rotation of inclined nose 76 of the clutch element 74. In this condition the clutch 74 may move past the clutch shifter without being shifted.

As the shaft 48 rotates, a cam 90 (Fig. 2)

Thereupon further sufiicient rotation of the shaft 48 will bring the nose 76 into contact with the clutch shifter and effect disenga ement of the clutch elements, followed y arrest of rotation of the feed roll shaft 48, and idle rotation of the gear 6 thereon, rotation of the gear 6 ceasin 9:, however, as soon U as the pedal lever 3 is permitted to rise and ing the record strips and arbon sheets to be interleaved in superposed relation to each other and to the platen of the machine, with the advance form registering apertures 63 in registry, and in engagement with the aligning pins 65,.all of which may be accomplished by manual operation and roper threading of the record strips, the pe al 3 will be in its upper position, and the switch elements 14 and 15 out of contact. In this position both the clutch shifter 77 and the detainer 84 will be in their upper positions. Depression of the pedal 3 b the operator will make the circuit throug the motor and cause the gear 6 to rotate in a strip feeding direction. The shaft 48, however, will not be rotated until the recess 71 registers with the clutch element 7 4, whereupon the clutch element will be thrust into the recess, and continued rotation of the gear 6 will rotate the clutch element 74 and consequently rotate the feed roll shaft 48, the upper feed roll 53 rotatingsimultaneously by reason of intermeshing of the gears 51, 52.

In the present embodiment the arrangement is such as to disconnect the feed roll from the driving gear 6 upon completion of substantially one full rotation of the feed roll. As the feed roll rotates, the cam 90 rotates, and after rotation sufficient to carry the clutch nose 76 past the clutch shifter nose 81 has been accomplished, the cam 90 thrusts the detainer 84 to one side, with the result that spring 80, which has been compressed by depression of the pedal lever, is released and thrusts the clutch shifter upwardly into clutch shifting position, althou h the detainer 84 may still be held down by t e pedal lever. Rotation of the feed shaft 48 will continue until the clutch element 76 is shifted by the nose 81, as before explained, whereu on feed rolls will prom tly come to rest. Ilpon releasing the pedal ever the detainer 84 will be lifted, the tooth 83 thereof readil passin the inclined outerface of the toot 82, an the spring 85 thrusting the detainer tooth into registry with that of the clutch shifter, as soon as the cam ermits. Rise of the pedal lever also breaks t e circuit and the motor ceases to operate.

It will be noted that the circuit is broken between successive motor energizing operations of the pedal 3, so that even though the pedal be held depressed with the switch members in contact, only a definite amount of rotation of the feed roll will be effected. The means for disconnecting the clutch elements is also motor-controlled, so that the .the latter are loose.

tion on the are in withdrawn position or will promptly be withdrawn by the cam 68, and held retracted until nearthe completion of onerotation of the feed rolls, whereupon the notches 50 in the trucks will assume position relieving the record strips from the feed grip, thus loosening the record strips and adapting them for movement relative to each other. Just before, or while thus relieved, the cam 68 causes the aligning pins to enter the aper- I tures 63 in the strips and a slight further feed of the record strips will be effected by the rotative movement of the aligning pins. Next, the trucks will again resume friction grip on the record strips. In the interval between the release and regripping, the stri s are aligned relative to each other by t e aligning pins, which draw the strips while Promptly on regripping the strips, the clutch elements will be disconnected and the feed of the strips will cease.

When the record strips arefed by rotation of the feed rolls, the platen .2 is in lowered position so as not to retard the advance of the record strips. In case the used portion of one of the carbon sheets needs replacing, the pawl 27 for that articular carbon sheet may be moved out o restraining relation to the corresponding ratchet wheel 25. Thereupon continued advance of the record strips will also advance the unrestrained carbon strip untilan unused, or clean, portion thereof arrives in writing posiplaten. The used ortion may feed through'the feed rolls with the record strip and be torn ofi. Should the carbon strip be advanced toofar, or more thanis necessary, it may readily be retracted by rotating the carbon roll shaft 23 in reverse direction.

In case it is desired to replace used portions of all carbon sheets by unused portions, or by other portions, manual rotation of the shaft 35 in a clockwise direction will advance thecarbon supporting carrier a substantial amount. Thereupon, by depressing the pedal 3 the feed rolls may be actuated to cause motor advance of the record strips to take u the loop of carbon sheets ma by the a vance of the carrier. Or, if the 1 carbon carrier is not too heavy, the latches 42 maybe lifted, whereupon rotation of the feed rolls will advance the carbons and the carrier frame therewith. It will be noted that, by moving all the pawls 27 out of restraining position, the carbon sheets may be motor-advanced until their ends pass between the feed rolls to any desired extent.

In this position they may be torn off with the record strips. At the outside of the feed mechanism a tear-ofi bar (Fig. 1) may be provided. This may be unnecessary in case the record strips are provided with efiective transverse weakening lines.

A blocking strip 101 of soft and thin flexible material, as paper, may be inserted between one or other of the record strips and the next adjacent transfer face of the carbon sheet. In Fig. 1 the blocking strip 101 comes from a strip supply spool 102 rotatable on a supporting rod 103, the free end being in blocking position. The spool may slide along rod 103 to different position, or additional spool of such strip may be employed. As the blocking strip lies between a record strip and a transfer face of a carbon sheet and is in contact with such record strip it prevents transfer of printing impression to the area of such record strip lying immediately thereunder. When the blocking strip 'is soft, as is paper, it nevertheless permits record strips lower down to receive the impression. More or less of the printing data may thus be blocked out depending on the size and position of the blocking strip. If sufliciently large, it will serve to block out printin on an entire bill area. A plurality of blocking strips may be used if desired and may be inserted at different depths in the pile of superposed record strips. In this wise, the part or the whole of the typewritten data may be blocked from being printed on any one or more of the record strips.

Since certain changes may be made in the above construction, and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
