HARRY H. VIOKERS, OF CORONA, NEW YORK, ASSIGNOR TO UNDERWOOD COMPUTING MACHINE COMPANY, OF NEW YORK, N. Y., A
CORPORATION OF NEW YORK.
COMBINED TYPEWRITING AND COMPUTING MACHINE.
Specification of Letters Patent.
Patented Jan. 10, 1922.
Application filed October 23, 1920. Serial No. 418,884.
To all whom it may concern:
Be it known that I, HARRY H. VICKERS, a citizen of the United States, residing in Corona, Long- Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Combined Typewriting and Computing Machines, of which the following is a specification.
This invention relates to means for reduc ing the number of denominations in which digits may be entered, below the capacity of the register in which said entries are to be made, and is in the nature of an improvement on Patent No. 1,278,062, granted to me September 3, 1918.
In machines of the Underwood-Hanson type, such as disclosed in said patent, the number-keys are effective when the carriage is in a computing zone to set, by means of key-setting linkages, index-pins on pin-bars advanced seriatim to effective position by denomination-selecting means actuated by the carriage, and, when such indexing is completed, the pin-bars and the numberwheels to which they are connected may be actuated by the general operator in accordance with the setting of the index-pins. Such denomination-selecting mechanism usually includes a set of denominational jacks actuable by a tappet on the carriage and a set of thrust-links or rods to transmit the movements of the jacks to levers in the lower part of the machine.
In carrying out this invention, certain of the thrust-rods or links may be guided at their upper ends by means of a fixed plate, having perforations through which said rods project, the position of the upper ends of the rods being such as to enable actuation thereof by the corresponding jacks. Provision may be made whereby other jacks may be maintained in operative relation with respect to the corresponding jacks or may be moved to inoperative position with respect thereto. To this end, certain of the jacks to be shifted may project through suitable guiding openings in a plate supported on the lower arm of a pivoted lever having a suitable handle at its upper end, the parts being constructed and arranged so that the lever will remain in either effective or ineffective position when so p0- sitioned. Such levers and guiding plates may be provided at each side of the set of ]&CkS.
It will be seen that by reducing the range of the denomination-selecting mechanism, denomination-selectors may be placed closer together than is usually the case, for the selectors need to be separated only to an extent sufficient to prevent advancement of two pin-bars at a time, thereby permitting narrow columns to be written close together and cross-adding to be effected.
The same arrangement of the guiding plate and lever may be used to throw out of effective relation with the jacks all of the thrustbars associated with a single register, so that, when two or more registers are used,
any; of them may be rendered ineffective, at W1 Other features inafter appear.
In the accompanying drawings,
Figure 1 is a View showing my invention applied to so much of the machine of the Underwood-Hanson type as is necessary for the purpose of illustration. Figure 2 is a detail sectional view, show- 111g certain of the thrust-bars or links moved to IIIGHQCtlVG position by means of the corresponding controlling lever.
Figure 3 is a perspective view of the rear of a jack-housing, with a controlling lever at each side thereof.
Figure 4 is a view of a modified form of my invention, in which control of all of the thrust bars may be effected by a single handle.
As is frequently the case in machines of the Underwood-Hanson type, the typewritercarriage 10 is provided at its rear with one or more denomination-selectors 11, pivotally and slidably mounted on a rod 12 and held in adjusted position therealong by means of a notched rod 13. Normally, each denominationselector is in an ineffective, depressed position, but as the carriage 10, in its letterfeeding movement, enters a computing zone, a frusto-conical roller 14 on the selector 11 and advantages will herewill ride up the tapered end of a roller 15, extending across the computing zone, and the denomination-selector 11 will be raised to effective position, so that a tappet 16 thereon may cam up seriatim the forward ends of denominational jacks 17, pivoted at 18 in a housing 19. The rear ends of the jacks 17 overlie the upper ends of thrustrods or links 20, so that, upon actuation of the jacks 17 by the tappet 16, the thrustrods or links 20 will be depressed correspondingly, and, through suitable transposition mechanism, will advance the proper pin-bars to pin-setting position.
As herein disclosed, certain of the rods or links 20 may be guided in suitable perforations in a fixed plate 21, and the rods 20, at the left of said plate 21, may have their upper ends guided in suitable apertures in a plate 22, supported on the lower end of a lever 23, pivoted at 24 and having a handle 25 at its upper end. Provision may also be made of a plate 26, having perforations to receive the upper ends of the rods 20 at the right of the fixed plate 21, said plate 26 being mounted on the lower arm of a lever 27, pivoted at 28 and having a handle 29 at its upper end. In order to determine the proper position of the levers 23 and 27 when all of the rods 20 are to be actuated by the corresponding jacks, each of said levers 23 and 27 is provided with a lug 30 to engage a corresponding lever-supporting bracket 30", mounted on the rear of the housing 19. It should be understood that the levers 23 and 27 are so held at their pivots that although they may be moved by means of handles they will be yieldably retained in any position to which they are moved.
It will be evident that the capacity of the denomination-selecting mechanism may be reduced by moving either one, or both, of the levers 23 and 27 to move the corresponding rods 20 to ineffective position, the rear ends of the jacks 17 being curved upwardly to facilitate movement of the rods into and out of engagement with said jacks.
In Figure 4 is shown a modified form of the invention, in which all of the rods 20 project through apertures in a plate 31, supported at one end of a lever 32 and at the other on an arm 33, said lever and said arm being pivoted at 34 and 35, respectively, on brackets 36,. mounted on the jack-housing. It will be evident that all of the rods may be moved to and from effective position, at one time, by means of a handle 37 at the upper end of lever 32, the normal position of the lever being determined by means of a lug 38 on its lower arm coming into contact with the corresponding bracket 36.
In case all of the denominational jacks are effective for denomination-selecting purposes, the selectors must be spaced far enough apart so that two of them will not be effective on the pin-bars at the same time, for, if not sufficiently spaced, two pin-bars would be advanced at the same time and two pins set upon the depression of a numeralkey. Such action would lead to incorrect results. Certain classes of work involve the writing of small numbers and cross-computation thereof and, if the denomination-selecting mechanism is effective throughout its entire range, adjacent columns must be written with considerable space therebetween. It will be evident that by use of the present invention the effective range of the denomination-selecting mechanism may be reduced, to enable narrow columns to be written close together, or'restored to normal without any substantial delay. It should be noted that there is no change in the mechanism of the register itself but that the denomination-selecting mechanism is made ineifective for certain denominations.
Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
Having thus described my invention, I claim:

In a combined typewriting and computing machine, in combination, a carriage, carriage actuated denomination selecting mechanism including a set of denominational jacks and a set of denominational rods actuable thereby, a manually operable lever having its pivot in substantially the same plane as that in which said denominational rods lie, and a plate extending at right angles from one arm of said lever and provided with apertures to receive and guide certain of said denominational rods, said lever being frictionally held in any position to which it may be moved.
