CASH REGISTER.

' Application filed March 5, 1927. Serial No. 173,164.

This invention relates to improvements in cash registers, and more particularly type carrier setting mechanisms.

One of the objects of this invention is to provide an improved driving mechanism for adjusting type carriers.

Another object is to eliminate the complicated system of tube lines which is usually necessary in column-printing machines for setting separate sets of type carriers for each column.

With these and incidental objects in view, the invention consists of certain novel fea tures of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

General description.

This invention consists of a simplified means for adjusting a plurality of sets of type carriers, which are shown herein as type wheels used for column printing. The invention is illustrated as applied to a machine of the type shown and described in a co-pending application for Letters Patent of the United States of B. M. Shipley, Ser. No. 610,27 3, filed J anuary 2, 1923. In this type of machine a separate set of typewheels is provided for each column by means of which the data entered into the machine is printed. A separate printing platen is provided for each set of type wheels, but only one platen is released I for printing during any one operation. The.

if it is desired to print data entered into the machine in the right hand column, the data is set up on all four sets of type wheels, but only the hammer for the right hand set is released for taking the impression. V

In the above mentioned application a rather complicated system of tubing has been used for simultaneously adjusting all the sets of. type wheels. The present invention provides only one set of tubes, which is adapted to directly adjust one set of type wheels. The remaining three sets are adjusted by means of a sories'of internal gears which directly connect the various orders for adjusting these sets of type wheels according to the adjustment of the set which is set by the single set of tubes. Thus, a single shaft having mounted thereon an internal gear for the same denomination ineach set, connects all the type Wheels for that denomination together. As shown, there-areseven denominations ineach set of type wheels and, therefore, the machine is provided with seven shafts, each shaft carrying an internal gear Detail description.

The machine is provided with two type lines; one for printing on a slip, card or book, and the other for printing on a detail strip. Four sets of type Wheels (Fig. 6) are provided on each line, for the purpose of printing in columns. For example, the left hand set of type wheels, (Fig. 6), will print in the Withdrawal column, the second set of type wheels from the left will print in the Deposit column, the third set of type wheels from the left will print in the Old balance column, while the right hand set of type wheels will print in the New balance column.

Each set of type wheels 30 (Figs. 3 and 6) is loosely mounted on a short sleeve 31, which is carried by a stud 32 mounted in frames 33 and 34 (Fig. 6). The sleeves 31 are spaced on the stud 32 by means of spacing collars 35. The type carriers are adjusted by a differential mechanism which is well known in the art. The differential'for adjusting each set of denomination type wheels is controlled by means of a bank of keys 40 (Fig. 1) slidably mounted in a key frame 41, carried by

rods

42 and 43. A detent- 44 mounted on arms 45 maintains the key in its depressed position.

A differentially movable actuator 50 is operated by a driver 51 pivoted on a bearing 52. The driver 51 is connected to the actuator 50 by means of a latch 53 pivoted on a bell crank 54 and a link 55, both of which are pivoted on the actuator 50. The driver 51 is actuated by a pair of cams 56, secured to the cam shaft 57. The cam shaft 57 receivcs one complete rotation for each operation of the machine. (Io-operating with the pair of cams 56 is a roekable lever 58 which is connected to the driver 51 by means of a link 59. Thus when the pair of cams 56 is rotated, the driver 51 is rocked clockwise, thereby moving the actuator 50 clockwise until the bell crank 54 contacts the depressed key, or if no key is depressed, a reset spider 6O connected to the bell crank 53 engages a zero stop 61 whereupon the bell crank 54 is rocked to disconnect the latch 53 from the driver 51. In this manner the actuator 50 is positioned commensurate with the value of the depressed key or, when no key is depressed, is stopped at zero. 7

Pivoted to the actuator 50 is a beam 65, which is bifurcated to engage a stud 66 on a link 67. The forward end of the beam is adjusted to a position corresponding with the depressed key and the rear end is thereafter adjusted by means of a roller 62 carried by the lever 58 inthe wcll'known manner. 'In this manner the link 67 is adjusted to a posit-ion corresponding with the depressed key. The link 67 is connected at its upper end to a segmental arm 68. used for adjusting indicators, not described herein. The lower end of the link 67 is connected to an arm 69, loosely mounted on a shaft 70. Secured to the arm 69 is a segment 71, in mesh with a worm gear72, secured to a shaft 73. The shaft 73 is supported in the beforementioned frame 34 and in an auxiliary frame 74 (Figs. 1 and 6). Secured to the .shaft 73 is a segment 75 (see also Fig. 2),

which meshes with a rack 76. "The rack 76 meshes with a ear 77 (see also Fig. 4) secured to one end of a tube 7 8, upon the other end of which is a gear 79 which meshes with double gear 85.

one of the beforementioned type wheels 30.

The tubes 78 are supported on a rod 80, carried by the

frames

33 and 74.

Thus it is seen that when the actuator 50 is adjusted commensurate with the depressed key 40, the right hand set (Fig. 6), of type wheels 30 is adjusted accordingly. A novel construction has been provided for adjusting the remaining three sets of type wheels from the adjustment of the right hand set.

Meshing with the gear 79 for the right hand set of type wheels, is a double gear 85, having both internal and external teeth. The double gear has its bearing on a stationary disk 86, carried by a square rod 87. The rod 87 is carried by the

frames

33 and 74. The disk 86 is held stationary and the double gear 85 is permitted to rotate on the disk 86. The gear 85 and disk 86 are held in proper lateral alignment by means of spacing disks 88 (Figs. 5 and 6).

The disks 86 are each provided with a bearing (Fig. 3), in which is mounted an interior gear 90. All of the interior gears are connected for uniform movement by means of a square shaft 89 (Fig. 4). As shown herein, seven shafts 89 (Fig. 3), are provided, one shaft being provided for each denomination of type wheels. The interior gears 90 are loosely mounted on the shafts 89 but are held in proper alignment, with the internal teeth of the double'gears 85, by

means of the spacing disks 88 (Fig. 5). How ever, inasmuch as the shafts 89 are square shafts the shafts will turn with the gears 90 when the double gears are rotated. Plates 91 (Fig. 6) maintain the shafts 89 in proper lateral alinement.

As before mentioned, a shaft 89 is pro-- vided for each denomination of type wheels. An interior gear 90 is mounted on the shaft 89 for engaging each double gear 85 for like denominations in each set of type wheels. Fig. 4 shows the units denomination wheels for all four sets connected together by one of the shafts 89 and the interior gears 90. Thus when the gear 79 is adjusted by the tube 7 8 for adjusting the type wheel 30 for the units denomination of the right hand set of type wheels the gear 79 will also adjust the Adjustment of the double gear 85 causes the interior gear 90 co-operating therewith, to rotate, thereby rotating the shaft 89. The rotation of the shaft 89 causes all of the interior gears 90 of the remaining three sets of type wheels to rotate, thereby rotating thedouble gear 85 for each unit type wheel. The external teeth of the double gears 85 in the remaining three sets mesh with the gears 79, which are loosely mounted on a sleeve 92 carried by the beforementioned rod 80. -The gears 79 for the three remaining sets mesh with the type wheels 30 for the upper and lower type lines.- Thus it may be seen that the adjustment of the right hand sets of type wheels is effected by means of the rack 76 and gear 79. Only one tube line is required and the remaining sets of type'wheels are set up by the internal gear mechanism. In this manner the complicated tube system'for adjusting the type wheels, such as is shown in the above mentioned application, is entirely eliminated.

The construction illustrated herein is very simplebecause it is not necessary to secure the gears 90 or the disks 86 to the respective shafts. If there should be any desired variation in the location of the type wheels, all that is necessary to do is to provide the proper length shafts 89 and the proper spacing disks 88, and the gears 90 and disks 86 can be located on the shafts by merely sliding them into position. By dividing the disks 86 into eight equal divisions for heat ing the shafts 89, and by using the square shaft- 87 .a standard disk 86 is provided. This disk can be located radially on the shaft 87 in any one of four positions for properly locating the bearing for the interior gears 90. By reversing the disks 86 four more radial locations are possible. Thus the disk 86 is standard for all possible positions, which construction simplifies manufacturmg.

The construction illustrated herein is adapted to set up as many sets of type wheels as desired. In the present disclosure only four sets have been shown by way of illustration. However, there is no limit to the number of sets of type wheels that can be adjusted by means of this construction, and therefore the use of very complicated tubing systems may be avoided.

It will be noticed that the right hand set of type wheels (Fig. 6), is provided with eight denominations instead of seven, as in the case of the three left hand sets of type carriers. in the illustrated system, for printing in the New balance column. The New balance column is provided with an overfio'w wheel because at times a larger amount must be printed from this setof wheels. This eighth wheel is positioned by means of a rack 76, which is adjusted by the overflow differential actuator 50 and is adapted to engage a gear 95. The gear 95 is connected to one end of a sleeve 97. which has fastened to theother end thereof a gear 98 (Figs. 3 and 6), mesh? ing with the upper and lower type wheels 99. Parts of the units type wheels 30 in Fig. 3 are broken away to show portions of the type wheels 99. The sleeve 97 is loosely mounted on a rod 96. Inasmuch as the eighth type wheel in the right hand set of type wheels is not connected to any of the type wheels in the three left hand sets of characters, no double gears are provided for this wheel.

The outermost tube 78 (Fig. 6) is sup- This eighth type wheel is. used,

ported in a hollow stud 100, which is secured in the frame 34. The outer end of the stud 100 is supported by means, of a bracket 101,

which also acts as a support for the-studs 32 and rod96. Two auxiliary brackets 102 and A brief description of the operation of the present invention will now'be given.

The differential mechanism is positioned according to the value of the depressed key. This movement is transmitted to the right hand set of type wheels by means of racks and a train of gears which adjust the type Wheels by means of a single set of tubes. The movement transmitted to the right hand set of type wheels is also transmitted, by

means 0 a set of double gears having internal and external teeth, to any number of wheels of like denomination. The internal teeth of the double gears mesh with interior gears which are connected by a shaft to interior gears for the various sets, thereby transmitting the movement to the like denominational elements of the three left hand sets of type wheels. A separate shaft is provided for each demonination and, therefore, the movement given to each denomination is transmitted to the like denomination of the remaining sets of wheels for each shaft.
