GenemZ description Described in general terms the machine is a small portable register adapted to be placed on a stand or hung on the wall in a house, where it may be used by the various members of the family or servants in recording household expenditures.

The machine includes a classified record strip of paper upon which entries are made of the various items for which money is paid out. he items recorded on the record strip may be set up by index levers for accumulating the amounts in a totalizer when an operating crank is given cycle of movement.

A small receptacle in the form of a drawer provides a convenient filing place for receipts received from the various expenditures Specifically described, the machine includes a frame 30 (Figs. 1 and 2) provided with an ear 31 formed at right angles there to. This ear supports a rod 32 upon which is freely mounted a supply roll of record paper 33. This paper is wound upon a wooden core and rotates against the friction tension of a disk 35 and a spring 36. This supply roll is adapted to be rotated by a knurled knob 37 which has two pins 38 penetrating the wooden core The sup ply roll and knurled knob are held in position on the rod 32 by a screw 39.

Res u to Fig. 1 it may be seen that the record strip is supplied i ith ruled lines so that the entries r ay to a classified index plate 51 which is cured to a casing 52 enclosing the mechanism of the machine.

Totalizer The various items entered upon the record strip may also be accumulated in a totalizer which furnishes a reading total of the expenditures. This totalizer is placed at the top of he machine and consi a plurality of wheels. Each of the whe includes a circular band 58 upon which are or 'aved three groups of digits. band is nr. .rcne-i to a formed disk 59 g i} secured t hub 60 by a collar 61. Secured to the r 59 by rivets 69 is a disk 63 PLOVltlQCl w a plurality of elongated open s (3% (ll. 8)

equal in number to the di on the b; i 58. Loosely fitted in each of these elem; openings is a slidable projec -table stop 0 (Figs. 1, 8 and The right hand end 0:; the stop is guided by open' formed in the disc 59 of the totaiizcr (Figs. 8 and 9). These lagtd to be moved laterally by means v- "iich hereinafter be described. Each s vided with shoulders to arrest it in and operated positions.

A spring clamp 67 adapted to retain the SLOP 6 stops are at home position or operated 10s spring clamp is positioned bet-wee supported a= 59 and the disk The total zer upon a shaft 68 end by a bracket 69 fastened to the frame of the machine, and at the lefthand end by a bracket 70 which is also secured to the frame of the machine. The shaft 68 is provided with two grooves 71 (Figs. 1, 3 and 8) formed on opposite sides of the shaft and running in the direction of the length of the shaft. Slidingly and non-rotatably mounted on the shaft 68 are disks 72 placed between the hubs 60 of the totalizer wheels. These (.llShS have two lugs 7 3 (Figs. 3 and 8 which are loosely fitted in the grooves 7i in the shaft 68. Near the left-hand end of the shaft 68 (Fig. l), and contacting the lastdisk 72, is a sleeve 77 loosely fitted on the shaft and constantly forced toward the disk 72 by a compression spring 78 entwined about the shaft 68. The function of this spring is to furnish a sufficient friction be tween the disks 72 and the hubs 60 of the ilizer wheels to cause these wheels to r0- LU tate with the shaft until they meet with an obstruction which will hereinafter be described. The amount of compression of the spring 78 is controlled by an adjusting nut 79 applied to the left hand end of the shaft 68. Tl is nut is retained in adjusted position by a pin 80.

The shaft 68 is rotated by manually operated crank 81 (Figs. 1, 2 and 6) pinned to the right hand end of the shaft and projecting to the outside of the casing of the machine. This operating crank is turned in the direction of the arrow, shown in Fig. 2, and is prevented from retrograde movement a ratchet wheel 82 (Fig. 4) pinned to a drum cam 83 secured to the shaft 68. Cooperat-ing with the ratchet wheel 82 is a spring-actuated pawl 84., pivoted on a stud 85, supported in a bracket 86, projecting upwardly from the frame of the machine.

The amount of rotation of the to'talizer wheels is predetermined by a plurality of index levers adjacent to each of the wheels. Each index lever mounted on a hub 91 loosely titted on the hub (50 of a totalizer wheel (Fig. 1). A. spacing coliar 92 is provided to maintain the index levers in their lateral positions with a sufficient working clearance between the hubs of the levers and the totalizer wheels to permit the levers to be moved imlependentlv of the wheels. Integral with the index lever 90 is a notched plate 9 3 (Fig. 8). which coo erates with a spring actuated pawl 94- to retain the index lever in its various set po sitions. This pawl is freely mounted upon a stud 95, supported in a bracket 96. secured to the frame of the machine. The index levers protrude through a slotted indexing plate 97 (Figs. 6., 7 and 8). which has a plurality of sets of digits engraved parallel with the slots. F astened to each lever guiding pointer 98 to assist the operator in properly selecting the desired digits.

The indexing plate 97 is also provided with round openings 99 through which a read ing of the totalizer wheels may be taken. The indexing plate is supported at both ends by brackets 100 and 101 secured to the frame of the machine and held in place by screws 102 engaging elongated openings in the plate. These elongated openings permit the indexing plate to be moved laterally by a cam groove 103 (Figs. 1 and 7) cooperating with a roller 10st mounted on a stud fastened in the indexing plate. The lateral movement of theindexing plate occurs near the beginning of the operation of the crank 81, the plate being moved toward the right and then immediately returned to home position. The timing for this cam 103 is shown in Fig. 14.

Tappets 108, (Fig. 10) are provided with openings through which the levers 90 extend, and are adapted to be moved difl'eren tially with the levers in the slots formed in the indexing plate 97 and also are adapted to be moved laterally by the plate 97. Each tappet 108 is guided in the slot of the indexing plate 97 by a flange 109 and a stud 110. The opening in the tappet 108 through which the lever 90 extends is of sufficient width to permit the tappet 108 to move laterally with the indexing plate 97 without any lateral movement of the lever 90. The tappet 108 (Figs. 9 and has a downwardly extending flange 111 which is placed in alinement with one of the various projectable stops by the index lever, and as the operating crank 81 is turned, and the indexing plate 97 moves laterally to the right, the flange 111 will engage the stop 65 and move the latter toward the right until its right hand end projects out a sufficient distance to act as a stop for the totalizer wheel as it comes into contact with a shoulder 112 (Figs. 5 and 8) of a pivoted lever 113. As the stop 65 engages the J shoulder on the lever 113, that particular wheel will cease to move with the shaft 68 in its cycle of operation. For example, if an index lever is moved into alinement with the digit three, the stop 65 in alinement :"i with the flange 111 is projected out of normal position and the totalizer wheel rotates with the shaft 68, by the friction disk previously described, until the stop contacts the shoulder 112, (Fig. 12) which permits three divisions of movement of the wheel. as previously stated. Each totalizer wheel is provided with three sets of digits which affords ample time in a single cycle of rotation of the shaft 68 to operate the various devices prior to and after the movement of the totalizer wheels when they move their greatest extent, which is ten divisions of movement.

As a totalizer wheel moves from nine to zero, it is necessary to carry one to the wheel of next higher order. For this purpose three brackets 114 (Fig. 8) are secured to each digit wheel. Any one of these brackets may engage the lower end 115 of the lever 113 (Figs. 5, 8, 12 and 13) and move this lever in a clockwise direction from the position shown in Fig. 12 to the position shown in Fig. 13, thus moving the shoulder 112 out of the path of the projected stop 65 carried by the totalizer wheel. With this lever out of the path of the stop 65, the totalizer wheel is permitted to move an additional step (from position in Fig. 12 to position in Fig. 13) during the rotation of the shaft 68, when it is stopped by the projected stop 65 engaging a shoulder 116 (Fig. 5) formed on an arm 117 projecting from a laterally sliding bar 118 guided by two studs 119 fastened in a bracket 120 secured to the frame of the machine.

The tripped transfer levers 113 are restored to their normal positions at the beginning of the operation of the machine by pins (Fig. 5) mounted in downwardly extending arms 126 of the indexing plate 97. These pins engage the ends 115 of the levers 113 (Figs. 5 and 8) as the indexing plate 97 (Fig. 6) is moved toward the right by the cam groove 103 (Fig. 1) previously described.

The transfer levers 113 are retained in either their home positions or their operated positions by tension springs 121 (Figs. 8 and 11). These springs are each in the form of a split ring and each encircles the coneshaped head of a pin 122 secured by its opposite end to the transfer lever 113. Each spring 121 is slightly expanded in placing it in position so that its closing-in action against the cone will cause a downward pressure on the pin 122, thereby creating friction between the under side of the transfer lever 113 and the top of a sleeve 123 secured in the bracket 120.

The totalizer wheels are normally locked against rotation by projections 127 (Figs. 1 and 5) formed on the arms 117 entered into slots 128 (Figs. 1 and 3) formed in the totalizer wheels. The bar 118 (Figs. 1 and 5), with which the arms 117 are integral, is moved laterally by a cam groove 129 (Fig. 1) cooperating with a roller 130 mounted on a stud fastened in said bar. The cam groove 129 is formed so as to move the projections 127 from the position shown in Fig. 7 to the position shown in Fig. 12 to unlock the to talizer wheels at the beginning of the opera tion of the crank 81 and then move these projections 127 from the position in Fig. 12 to the position in Fig. 7 to again lock said wheels near the end of the operation. The timing for this cam 129 is shown in 14c.

As the bar 118 returns to home position to lock the totalizer wheels, the arms 117 will simultaneously engage the projected stops (Figs. 8 and 9) and return them to home positions.

The machine is provided with a sliding drawer 13G (Figs. 1 and 2) which furnishes a convenient place in which to file receipts received from the various monetary transactions. Access to this drawer is bad by sliding' the drawer toward the right by the aid of a fin 'er grip 137.

Operation In using the machine for the purpose for which it is intended, when money is paid for household items coming under the various classifications, as shown by the record strip index plate in Fig. 1, the proper entries are made upon the record strip. As the exposed portion of the record strip is filled with entries the knob 49 of the upper or receiving roller is turned to move additional unused record material into writing position. To review entries which have been moved ahead of the writing position or out of view, the lo er knob 37 is turned in a reverse direction.

After entering the items upon the record strip, corresponding items or amounts are set up by the index levers 90, (Fig. 6) after which the operating crank 81 is given one cycle of movement to enter the item or amount in the totalizer. The total accumulated can be read at any time through the openings 99 provided for that purpose. The totalizer wheels may be reset to zero at any time by moving the index levers 90 to the digits on the indexing plate 97 corresponding to the complement of the digits on the totalizer wheels showing through the openings 99 and then operating the crank in the usual way. he customary receipt received when paying out money may be filed in the drawer or receipt compartment designated Receipts in Fig. 2.
