TABULATOR.

Appticatton tiled January 11,

To all 'whom 'it may concern:

Be it. known that. I, Enwtx B. CRAM, a citizen of the United States, residing at Vllt-ooi'- lyn, Kings county, 1New Yori., have invented certain new and useful Improvements in Tabnlators, ot which the following isa speci tication.

This invention relates to tabulators Al'or typewriting machines, and the principal object of the invention is to build the tabnlator into and make it a permanent part of the machine.

Further objects are to improve the construction and the inode of operationV of devices of this character.

'lf he invention will be fully described hereinafter, reference being` had to the accompanying dvawings, in which z- Figure 1 is a plan view of my improved tabulator and so much of a typewriting inachine as is necessaryxto show the tabulator built into it; Fig. 2 isa vertical longitudinal section; Fier. 3 is a vertical transverse section; Fig. z4 is :rfront elevation of a portion of the mechanism. Fig. 5 is an enlarged side view of a tabulating stop; Fig. 5 is a view of the tahulating stop showing the A parts separated. Fig. 6 is a plan view of the.

same; and Fig. 7 is an end view of the tabulating stop levers.

The frame A of the machine is suitahl)T constructed to support the operating parts including the typewriting mechanism (not shown), a transversely movable paper carriage l) carrying the usual cylindrical platen Pand one or more suitable tabulating stops 43, stop engaging devices shown as levers M for engaging with the tah'ulating stops` suit ably marked tabulator keys l, and suitable.

-tn connecting mechanism `for controlling the stop levers M. and means X operatively related to the levers M for releasing the carriage from the means for accomplishing the. step h v step movement during the operation carriage is free to move under the intiuenct` of the usual spring motor or other means except when restrained b v the engagement of levers M with stops 43'. y

A harias, preferably square, is. supported on the typewriter carriage D and has a scale on its upper face. and vertical grooves t0 on its rear face coincident with the gradnations of the scale. Above the bar 38 a rod 4t I 56 rigidly supported on the carriage and has! Spectcntion ot Letters Patent.

two flat sides at an angle to each other. The rod 41 supports tht` tabulatingstops 43, which may turn and slide freely upon it. A slot is cut in one edge ot each stop to receive one end of a tiat spring (34, the t'ree end of 60 which is adapted to engage. the lint sides on the rod 41 to hold tbe stop in definite positions, Figs. 5 and t3. The slot in the stop may be of such width that the walls therewith will bear so close against Ythe faces of '65 the spring as to hold the latter in position or the spring may be secured to the stop h v solder or any other suitable means. The free end of the spring is slotted and lies on both sides-oi the stop. .'hen not in use 7u these stops will preferably extend horizontally, Fig. 2, but when required for use a stop will be turned downwardly into one of the grooves 40 and will project rearwardly 4froni'the groove. The maximum number ot' 75 stops El which will ever be required should he placed upon the rod 4l when the machine is assembled and ordinarily a number of these stops will be out of service.' To enable the unu'sed stops to be moved out of the way so of those in service, the rod t1 is made to extend beyond' the service positions of the stops, that is. in the construction shown. heyond the part of the bar 38 which is provided with the grooves 40. and this extended a5 portion SG provides a storage place to which the unused stops can be slid out of the The stop leversl M are pivoted on a rod secured in the vertical side walls 30, of a pocket or chamber 251, which are preferably cast integral with the frame of the machine. 'lach lever M has a lateral arm 74 which has a notch T.) at its upper outer corner and the -lever has a vertical arm (39, to the lower end of which a rod 1T is pivoted. rlhe other ends oi the rods 1T are pivotally connected to the. lower ends of levers 15 which rock on a rod (Sti rigidly supported by the frame A.

mechanism. as the springs 90 hold the levers M out of the patti of stops lf however, it is desired to write a number in its proper location in a tabular space, the appropriate one of the tabulating` keys L is epressed thus causing the rod 17 to move toward the t'ront of the machine. This movement of the ItY rocks the one of the levers M connected to' it. so that the end of its arm 7l is carried into the path of stops 48 and also, by the engagement of a collar 99 with the bar it), the upper end of the arm 109 is carried toward the rear of the machine thereby disengaging the dog 4G from the carriage rack. The carriage then moves until a stop 43 engages with a lever M when the desired number may be Written. Let it be assumed that it. is desired to write 150.25 in its proper tabular position. The i ey L marked 100 is tirs-:t depressed. This rates the fifth lever M from the right .iand end and after the carriage has come to rest against this lever, which will occur when the printing point is in the hundreds column, the key L may be. released and the number written in the usual manner. So the proper position of the carriage may be obtained for any number by depressing the key L corresponding to its lefthand figure.
