CALCULATING-MACHINE.
Specification of Letters Patent.

Application filed August 16, 1918. Serial No. 250,158.
are manually adjustable by means of rotatable adjusting disks.
An object of my invention is the provision of a calculating machine of this class in which the operator can simultaneously reset to zero position all of the setting disks and adjusting disks.
In carrying out my invention, I provide a pluralityof pinions secured upon a com mon shaft for simultaneous movement and which cooperate with teeth on the setting disks so that by rotation of the pinions, the
setting disks can be returned to the zero position. The shaft for the pinions is movable longitudinally so that the pinions may be moved into or out of mesh with the set-' ting disks, the mechanism for shifting the shaft being operable automatically upon r0- tation thereof.
I will describe one form of mechanism embodying my invention, and will then- Fig. 4 is a vertical sectional view taken on the line BB of Fig. 2, and showing the adjusting disk in normal position.
Fig. 5 is a view similar to Fig. 4: with the adjusting disk revolved part of its way toward the zero position.
Figs. '6 and 7 are cross sectional views.
of the adjusting disks l7.
Fig. 8 is a view similar to Fig. 5 show ing oneadjusting disk in Zero position.
9 is a vertical sectional view illustrating the mechanism for connecting the totalizers to the mechanism forming the subject matter of the present invention.
Similar reference characters refer to similar parts in each of the several views.
Referring specifically to the drawings, 1 designates the setting disks which are rotatably mounted upon a shaft 10 suitably journaled in a casing 13. The setting disks 1 are of the usual type having the teeth 2 which are adjusted by means of the adjusting disks 3. The adjusting disks 3 are fixed to the shaft 10 and are provided with operating handles 22, whereby the disks are oscillated to adjust the teeth 2 in a manner which is well understood in the art. A major portion of the periphery of each disk 3 is provided with teeth l, which, as shown in Figs. 3 and l, mesh with pinions 5 fixed at regular spaced intervals to a shaft 6 journaled in bearings 8 supported upon the base plate 7. As shown in Figs. 2 and 3, the left hand end of the shaft 6 is provided with a cog wheel 9 fixed to the shaft for rotation thereof. Loosely fitted on the shaft 10 at a point directly above the cog wheel 9 is an operating disk 11 which is provided with teeth 110 which mesh with the teeth of the cog wheel 9, as illustrated to advantage in Fig. l. The operating disk 11 is adapted to be manually oscillated by means of an arm 12 secured to the disk and projecting through a suitable slot formed in the casing 13. As shown in Fig. 1 the disk is biased to normal position by means of a coil spring 21, so
. that when moving the disk fromthe posi tion shown in Fig. 1, such movement is against the tension of the spring. Mounted on the right hand. side of the cog wheel 9 is a pawl 14; which is biased into engagement with a ratchet 16 by .means of a spring 15.
The arrangement of the pawl and ratchet is such that the shaft 6 is free to rotate in a clockwise direction, as viewed in Fig. l, independently of the cog wheel 9, but when rotated in the opposite direction, the pawl lei engages the ratchet 16, thus locking the cog wheel to theshaft and causing the two to rotate together. 7
The shaft 6 is mounted in such a manner that it is capable of being shifted longitudinally so, that the pinions 5 may be thrown into or out of mesh with the adjusting disks 3. hen the shaft is in either extreme position, the cog wheel 9 meshes with the operat-.
of the cog wheel is equal to or greater than the shifting movementof the shaft 6. When the shaft 6 is in the normal position, as
shown in Fig. 2, the pinions 5 are, disalined with relation to the adjusting disks 3, but when the shaft 6 is shifted to the active position as shown in Fig. 3, the pinionsb move into mesh with the teeth'tof the disks 3.
T he shifting of the shaft 6 from normal to active positionis accomplished by the mechanism which is actuated upon the rotationof the shaft 6. through the cog wheel 9 and the operating disk 11. This mechanism is as follows: i
As shown in Figs. 2 and 3, the right hand end of the shaft 6 is provided with acam 1 having the outer edge thereof formed with a recess 170, one wall of which is inclined as at 20, as clearly shown in Figs. (Sand 7. Secured to the base plate '4 IS'H. pm 18 which normally lies within the recess 170, as shown in Fig.2. Surrounding that portion of the.
sired to return the setting mechanism 'to zero position. To secure this restorationof the mechanism, the operating disk 11 is partially rotated in the direction indicated by the arrow 11 in Fig. 1, whereby the pinion 9 together with the shaft 6-are rotated in the direction-indicated by the arrow 1 in Fig. 1. With the rotation of shaft 6, the latter is shiftedfrom the normal position to the active position so that the pinions 5 now mesh with the teeth 4c of the adjustingdisks 3. Upon continued movement of the operating disk 11 to the final po'sitiomth'e pinions 5 now rotate the adjusting disks 3 in-the direction indicated by the arrow in Fig. 4, whereby the disks 3 and consequently the setting disks 4 are returned to zero position;
During the movement of the arm 12, from the starting position to the final position, as shown in Fig. 8, the shaft 6 has completed one revolution, so that the pin 18 again rests within the recess 170. Upon releasing the operating disk 11, the spring 21 returns the same'to normal positionwithout rotating the shaft 6, as the cog wheel now rotates independently of the shaft.
In. Fig. 9 is illustrated the mechanism above described connected to the totalizers. Upon rotation of the setting disks on the shaft 10, the values set on the setting disk 1 are transmitted by means of gears 23 mounted on ,a stationary shaft 26, to gears 24: of the totalizers. The gears 245 are loosely mounted on the shaft 27, and have rigidly secured thereto wheels or disks 28 provided on their peripheries with the characters 1 to 9 and the 0 sign. The totalizers together with the transmission gears 23 and the shaft carrying the numeral disks28 andthelr gears 2 1 are all :mounted on'a carriage be made herein withoutdeparting from the spirit of the invention, and the spirit and scope of the appended claims.
