Specification 01 Letters Patent.
Patented Mar. 2, 1915.
Application filed April 7, 1913. Serial No. 759,494.
To all :whom it may concern: Be it known that I, Or'roTnnzun, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvewhich- Figure 1 is a skeletonized side elevational view of my improved tabulating mechanism. Fig.2 is a front elevational view. Fig. 3 is a rear view of the upper portion of the tabulating bar showing the-same in its normal position, and Fig. -l is a similar view showing said tabulating bar in its raised and locked position.
This invention relates to a new and useful improvement in tabulating mechanisms for calculating machines and is designed to be, automatically operated at every operation of the operating rock shaft of the adding mechanism for purposes set forth in a companion application filed by me of even date herewith, serially numbered 759,-i93.
One of the objects of my invention is to provide an automatically operated tabulating inechanism which will permit the tabulating bar to be elevated and locked in its elevated position, while its operating medium is restored to its normal position. after which the paper supporting carriage with its adjustable tabulating stop or stops will engage the upper end of the tabulating bar. release the same and permit it to return to its normal depressed position. The tabulat ing bar, as shown, disables the escapement mechanism, usually employed to letter space the paper carriage leftwardlywvhen ,it is raised, and when said bar is released and returned to its normal position, the engagement between the esca-pement mechanism and the carriage rack is reestablished so that the carriage is held in its tabulated position.
'In the drawings 1- indicates the base of the machine from which rise suitable standards for supporting a topfplate 2. On this top plate is arrangd a metal housing 3 constituting a guide for the upper end of the tabulating bar 4. This bar is provided witha pin 5 at its upper end which cooperates with a lug .6 .in the housing, said bar being slotted and guided by a pin 7 extending across the housing. A spring 8 tends to hold the bar with its pin 5 in" frictional engagement with the lug. In the normal position of the parts, as shown in Fig. 3, the upper end of the bar is depressed and out of the path of the adjustable tabulating blocks. 9 mounted on the rod 10 and engaging the notched surface of part of theframe 11 of the paper supporting carriage. The blocks are rotate on their rod and in this manner may be adjusted as desired. Preferably a plurality of' blocks'are employed, the number used depending upon the character of the work being done. The tabulating bar 4 is provided with a shoulder 12 which cooperates with a swinging plate 13 and when said bar is raised. the plate will move the upper end of the escapenient shaft 1% and its carried pinion 15 out of mesh with the rack 16 on the paper carriage. Hence when the bar 14 is raised, the connectionbetween the escapement mechanism and the carriage is interrupted and the. carriage will move leftwardly under the iinpelling action of its spring until a block 9 engages with the elevated tabulating bar.
;\s shown in Fig. 4. when the tabulator har -l is raised. the pin 5 will be on top of the lug (v and lock the bar in its raised posi' tion until the next tabnlating block 9 on the paper carriage engagesthe elevated end of said bar moving the same laterally so as to more the pin 5 from over the lug 6 when a spring 16 connected to the bar 4- will draw the bar 4 downwardly which downward movement refistablishes connection between the pinion on the upper end of the escapement shaft and the rack on the paper carriage. In, this manner, the carriage is held in its tabulated position.
The lower end of bar 4 is guided in a plate 17 and is provided with a block or projection 18 on the under side of which an adjustable screw 19 is intended to engage for the purpose of raising the bar 4. This screw 19 is mounted in the end of a rock arm 20 fixed on a rock shaft 21 of the adding mechanism. Another rock arm 22 carries a tappet'23 at'its end which cooperates with a pm 24 on a rock arm 25 mounted on the operating rock shaft 81'. When the arm 25 is rocked forwardly, it will idly pass over the tappet 23 which tappet is made yielding by means of a suitable spring and after passing beyond said tappet, the pin 24 will permit the tappet to rise in its path, whereby on the backward stroke of the arm 25, the pin 24 will engage the 'tappet and depress the arm-'22. 'lhis will cause the arm 20 to rise and set the 'tabulatingbar 4. \Vhen set, the tabu'lating bar is locked in its elevated position, therising movement thereof disabling the escapement mechanism and permitting the carriage to be drawn leftwardly until the next block 9 engages the-elevated end of the tabulating bar, moving the pin 5 from over the lug 6 and permitting the spring 16 to retract or lower the bar 4 in readiness for another operation. And in this manner, the lowering operation of the bar 4, the connection between the escapement pinion and the rack-0n the paper carriage is reestablished and the carriage is consequently held in its tabulated position.
Whatl'claim is:
In a tabulatin mechanism, the combination of a tabulatlng bar, a rock arm for operating said bar, said rock am having an adjustable screw in its end whereby the stroke of the bar may be adjusted, another rock arm having a yielding. tappet on its end, and a third rock arm having a pin for cooperating with said yielding tappet whereby the operating mechanism for the tabulating bar will be actuated near the end of the return strokeof said in.
In testimony whereof hereunto afiix my si nature in the presence-of two witnesses.
this 2nd day of April, 1913.
