CALCULATING-MACHINE.

Specification of Letters Patent.

Patented Oct. 14, 1919.

Application filed March 25,1914. Serial No. 827,049.

To all whom it may concern.

Be it known that I, OTTO MALOHER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Ill1no1s, have invented certain new and usescribed and illustrated in my application Serial No. 825,782, filed March 19, 1914.

This totalizer is designed to embody an improved carrying mechanism of the delayed type, which is positively driven after the completion of a calculation, and wherein. the number-bearing members or wheels of the totalizer are constantly trued. It is also desired to reduce the number of parts embodied in the totalizer, thereby producing a simple, positive and inexpensive totalizer. With the above and other objects in view, as will be apparent, this invention consists in the construction, combination and ar rangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, Wherein Figure 1 is a fragmentary plan view of a calculating machine illustrating in detail the totalizer forming the subject-matter of the present invention;

Fig. 6 is a fragmentary vertical sectional view of the operating dogs for imparting motion to the driving mechanism.

The 'totalizer forming the subject-matter of the present invention comprises a plurality of number-bearing members or numeral wheels,which are rotatable by a plurality of reciprocal racks in either direction. The present invention provides two posi tively driven carrying shafts, operable in reverse directions, which carry sliding carrying gears, each shaft carrying one gear for each denominational order of the nu- These carrying gears are meral wheels. 7 operable only when the calculation upon the numeral wheels has been completed, which calculation sets the carrying gears for operation. Two sets of carrying gearsare provided for one totalizer, one of which cotion of rotation thereof, so that when the totalizer is operating subtractingly, one set .of carrying gears will cooperate therewith,

and when it is operating addingly the other set of carrying gears will cooperate therewith, the rotation of the carrying gearspbeing regulated to correspond with the rotation of the totalizer, dependent upon the calculation: performed.

eferring more particularly to the drawing, 10 indicates a totalizer shaft mounted inthe frame or casing of the machine, indicated generally as 11. Loosely mounted upon this totaliz'er shaft are a plurality of units, one unit for each denominational or decimal order. Each unit comprises a numeral wheel 12, a star wheel 13, a driving gear 14 and a ten-toothed gear 15, by means of which the carrying is accomplished. These elements, to-wit, the numeral wheel 12, the star wheel 13, the drive gear 14: and the ten-toothed gear 15, are secured together and loosely mounted upon the shaft 10 for simultaneous rotation thereon. Keyed to the totalizer shaft 10 adjacent to each nuoperates with said totalizer for either direcrack will rotate this gear 17, thereby rotating the drive gear 14, the star wheel 13, the numeral wheel 12 and the ten-toothed gear 15. Thus it will be seen that the movement of the racks, which is designed to impart a variable movement to the number-bearing members, directly and positively operates the totalizer units.

In the machine with which the totalizer forming the subject-matter of the present invention is arranged to cooperate, a primary drive shaft 19 is provided, which is arranged to rotate a quarter of a revolution in the direction of the arrow X in Fig. 4, at each calculation of the machine. A collar or sleeve 20 is loosely mounted upon this primary drive shaft and carries at its inner terminal a large gear 21, which is arranged to mesh with and drive a gear 22 mounted upon and keyed to the secondary drive shaft 23, which rests in the same horizontal plane as the primary drive shaft 19. By the provision of the pawls 2e and 2e, Figs. 1 and 6, the primary drive shaft 19 is rotated a quarter of a revolution in the direction of the arrow X in Fig. 1, and at the completion of that movement the operating crank or handle 25 is released, which causes the sleeve 20 to take a quarter of a revolution in the reverse direction to the arrow X, Fig. 41. The operation of the parts 19 and 20 is produced by the pawls 24: and 2% carried by the projection 25 on the crank 25. The pawls 2t and 2st cooperate with ratchet wheels 19 and 20 connected with shaft 19 and sleeve 20 respectively. As the secondary drive shaft 23 is geared to the sleeve 20 at a ratio of 4 to 1, it will be rotated a complete revolution. The secondary drive shaft- 23 operates the printing mechanism and restores the various operating parts of the machine not forming a part of this invention. It is during the forward quarter cycle movement of the primary drive shaft 19 that the racks 18 are released to reciprocate forwardly to rotate the drive gears 1% through the medium of the movable gears 17, thus registering a number or item upon the totalizer.

In the totalizer forming the subject-matter of the present invention, the carrying operation is accomplished after the completion of the movement of the primary drive shaft 19 and during the operation of the secondary drive shaft 23, the carrying gears, however, being set during the movement of the primary drive shaft 19; that is to say, during the calculation.

Upon each side of the totalizer shaft 10 and arranged parallel thereto and in the same horizontal plane, are the carrying shafts 26 and 27. The carrying shaft 26 has a gear 28 keyed thereto which meshes with the large gear 21 carried by the sleeve 20 mounted upon the primary drive shaft 19.

This rotates the shaft 26 in the same direc tion as the primary drive shaft 19 and in the opposite direction to the direction of rotation of the gear 21. The carrying shaft- 27 has a gear 29 keyed thereto, which meshes with a wide gear 30 loosely mounted upon the automatic clearing shaft 31. One side of this wide gear 39 meshes with the gear 29, while the opposite side thereof meshes with the gear 21. By this arrangement, the carrying shaft 27 rotates in the same direction as the primary drive shaft 19 and in the opposite direction to the sleeve 20 and the large gear 21 carried thereby, and also in a direction opposite to that of the carrying shaft 26.

The carrying shaft 26 is arranged to cooperate with the totalizer when said totalizer is operating subtractingly, while the carrying shaft 27 is adapted to cooperate with the totalizer when said totalizer is operating addingly. Mounted on each carry ing shaft 26, 27 and keyed thereto for reciprocation are a series of one-toothed gears 82, which are staggeredly arranged upon their cooperating shaft so that said gears will cooperate with the units of the totalizer successively. One side of each gear is operated upon by a spring 33, which is interposed between the rack 18 of the co operating totalizer unit and the body of the gear, and encircles its carrying shaft. The action of this spring is such that if the cooperating carrying gear were not held from movement, as will be hereinafter apparent, the spring would force the carrying gear toward the opposite rack 18 to that against which the spring bears along the shaft until said carrying gear was alined with, the ten toothed gear 15 of the cooperating totalizer unit. It is apparent that as the shafts 26 and 27 are positively driven from the source of power after the calculation, all of the carrying gears 32 alined with their cooperating ten-toothed gears 15 will impart a step of rotation to the ten-toothed gears 15, thereby inserting 1 upon the units of the totalizer with which they cooperate.

The opposite surface of each carrying gear 32 is provided with a projection and collar 35, which are formed integral zherewith or otherwise secured. The collar 05 is provided with a cazn surface 36, which, as will be seen from Fig. 5, is arranged in close proximity to the tooth of the cooper-at ing gear and is arranged to follow said tooth. This cam surface is provided for returning the gear 32 to its inoperative and normal positi-n'i, and its arrangement with respect to the teeth of its cooperating is such that the return of the gear occurs immediately after the meshing of the tooth thereof with the cooperating ten-toothed gear 15. The ten-toothed gear 15 of each unit of the totaliiier is provided with a pin 37, projecting therefrom at a position equivalent to the position of the digit 9 on the cooperating numeral wheel 12 when said digit 9 is at or adjacent to the reading line. Loosely mounted upon the primary drive shaft 19 and under each unit of the totalizer,

is a yoke 38, which carries two fingers 39 extending vertically in the plane of the yoke, and an offset finger 40. A spring 11 is connected to the under side of each yoke 38 and to a stationary part 12 of the machine, said spring acting upon said yoke to hold the same in a normally vertical position. The offset arm 10 of each yoke cooperates with the pin 37 of one unit of the totalizer, while the fingers 39, 39 thereof cooperate with the carrying gears 32 of the unit of the totalizer of the next higher order, as

illustrated in Figs. 2 and 5, said fingers 39,

39 bearing against and engaging the projections 34cof said carryinggears. That is to say, if the finger 10 is engaged by the pin 37 of the ten-toothed gear '15 of the unit of the totalizer corresponding to the units denominational order, the finger-s39, 39 thereof will cooperate with the carrying gears 32 of the unit of the totalizer repre senting the tens denominational order, so that when the gear 15 of the units denominational order contacts with the arm the spring 41, one or the other of the fingers 39 will release its cooperating carrying gear 32 of the tens denominational order to aline the same with the ten-toothed gear 15 of said tens denominational order; and hence, when the carrying shafts are rotated after the completion of the calculation, one digit will be inserted on or subtracted from the tens numeral wheel by the meshing of the carrying gear 32 with the ten-toothed gear 15, dependent upon the calculation and d1- rection of rotation of the numeral wheels.

The rotation of the'numeral wheeland its cooperatlng elements, including the tentoothed gear '15 carrying the pin 37, will cause said pin 37 to contact with one side or the other of the finger a0 of the cooperating yoke 38. If the pin 37 cooperates with one side of the offset finger 40, one of the gears 32 uponone of the carrying shafts accomnlished to correspond to the .direction of rotation of the totalizer.

Immediately after the tooth of each carrying gear32 meshes with its cooperating tentoothed gear 15,the cam surface 36 thereof will contact with the adjacent terminal. of

the bracket 16 of the next adjacent unit of they are returned to'their normal and in active positions successively, immediately after the insertion of theextra digit.

The automatic clearing shaft 31 has a plurality of dogs 42 loosely mounted thereon, the terminals of which are arranged to enter between the teeth of the star wheels 13 to constantly keep each unit of the totalizer trued and to take up such lost motion as I may occur in the totaliz'er. The outer ends of the dogs 4L2 are acted upon by the springs 43, which extend and are secured to the collars 1 1 loosely mounted upon the secondary drive shaft 23. s

The automatic clearing shaft 31 also carries a plurality of clearing arms 15, which at their terminals are provided with the teeth 16 for engagement with the pins 37 of the alined ten-toothed gears 15. These arms are keyed to the shaft .31, and when said shaft is oscillated are arranged to have their teeth 46 projected into the paths of movementof the pins referred to. The shaft 31 is provided at its terminal with the dependent arm 47, which is pivoted to the slide 48. This slide is operated by the auto clear key 4:9. When theslide 4-8 is reciprocated,

the shaft 31 is oscillated, bringing the teeth 46 of the arms 45 into the paths of movement of the pins 37. i If the totalizer is operated addingly, the clearing thereof is accomplished by reversing its direction of rotation, which causes the totalizer to operate subtractingly.- Thus, when the shaft 31 is oscillated to locate the arms 15 as described,

the pins 37 contact with the teeth 46 to limit the rotation of the numeral wheels 12 and exhibit a series of zeros at the sight line. If the totalizer is operating subtractingly, no. change is made in the direction of rotation thereof, the shaft 31 being'merely oscill-ated to position the arms.

In this totalizer, the numbers to be registered are first set up on the keyboard (not shown),jwhich actsas a stop for the racks 18, which operate the totalizer. The crank 25 is then pulled forwardly, which. imparts a quarter of a cycle rotation to the primary drive shaft 19. Previous to pulling the crank 25, however, the shaft 50 is set to operate the mechanism 51 to determine the character of the calculation. The mechanism for setting the totalizer for adding and subtracting is not a part 'of the present inven-' tion and it is suflicient to say that it shifts the shaft 10 to bring the totalizer into operative relation with the upper or lower teeth of the racks 18 during the movement of these rac (s, the upper teeth operating the totalizer in one direction and the lower teeth in the other. During the first portion of movement of the primary drive shaft 19, the totalizer shaft 10 through the medium of the mechanism 51, is oscillated to bring the gears 17 carried by the bracket. 16 into mesh with one side or the other of the cooperating racks 18, which determines the direction of rotation of the totalizer.

The crank is then released and is returned to its normal, inactive position, under the influence of the spring 52, which causes the gear 21 to rotate, imparting such rotation to the secondary drive shaft 23 and to the carrying shafts 26, 27, both of which are positively rotated in opposite directions. If during the calculation it is necessary to perform any carrying, the yokes 38 are oscillated through the medium of the offset fingers 4L0 cooperating with the pins 37 of the ten-toothed gears 15, which sets the proper carrying gears 32, dependent, of course, upon the direction of rotation of the units of the totalizer. Consequently, when the carrying shafts 26 and 27 are positively rotated from the gear 21, all of the carrying gears 32 carried thereby will be rotated, and those which are set to cooperate with the tentoothed gears 15 will mesh with said tentoothed gears 15, inserting one digit on the numeral wheels rotating with such tentoothed gears 15, and are instantly returned to their normal and inactive positions for engagement with the cooperating fingers 39 by the cam surfaces 36 thereof, contacting with the adjacent terminals of the brackets 16.
