TABULATING DEVICE FOR TYPE-WRITING MACHINES.

I SPECIFICATION forming part of Letters Patent No. 767,838, dated August 16, 1904.

Application filed March 21, 1902. Renewed April 21, 1904. Serial No. 204,284. (No model.)

To all whom, it may concern:

Be it known that I, JEROME B. SEooR, a citizen of the United States, residing at Derby, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Tabulating Devices for Type-VVriting Machines, of which the following is a specification.

This invention relates to improvements in tabulating devices for type-writing machines; and its object is to facilitate the tabulating operation by providing column-stop devices .which can be instantly set to operate at any given column without necessity of careful adjustment by the operator.

With the usual tabulatingdevices it is necessary when a column is to be written in a definite part of a page to carefully adjust an adjustable stop to the required point. This requires time and care, and the removal of the stop to one side when tabulation is no longer desired also takes an appreciable time.

My present invention comprises the provision of column-stops that are not adjustable that is, are not movable longitudinally of the carriage-but may be moved laterally with respect to the carriage to bring them into or out of cooperative relation with the tabulating-key device. Said tabulating-key device may have a single stop-key or a plurality of keys to give a decimal or denominational stop.

In the accompanying drawings, Figure 1 is an end elevation with parts broken away of a type-writing machine, illustrating the invention. Fig. 2 is a partial rear elevation of the same. Fig. 3 is a detail view of a spring-drum provided with a peripheral graduated stop device, a as hereinafter described.

1 may represent the frame, and 2 the carriage, of any usual or suitable form of typewriter. The column-stop-controlling devices carried by the carriage consist of shiftable tappet-lugs 4, which in this illustration are shown as pivoted to swing vertically on the carriage-bar 3, so as to be brought into or out of cooperating relation with a cam device 10 on a bell-crank lever 10, pivoted at 10 to the machine-frame and engaging at its other end with a lever 11, pivoted at its lower end at 11 to the machine-frame and having an arm or lug 11., which extends under a series of stop-levers 12, pivoted on a pivot pin or shaft 13. These levers 12 are each formed at its end with a projecing nose, as shown in dotted lines in Fig. 2, extending obliquely downward and adapted to engage with stop means 14, formed on the periphery of the usual spring-drum 15, which is geared to the carriage in the usual manner. The stop means on the spring-drum may, as shown in Fig. 3, consist of oblique slots 14, formed in a band on the outside of said drum and having on their sides which engage with the stop-levers 12 steps 15', arranged at angular distances circumferentially of the spring-drum corresponding with the letter-space feed on the carriage. The distance asunder of the oblique slots 14 circumferentially of the-drum determines the distance between columns and corresponds with the distance between the tap petlugs 4, which may represent one inch, more or less, in the feed movement of the carriage. The steps 15 (here shown nine in number) in each slot 14 correspond with letter-spaces or decimal value of the figures in each column. There is one stop-lever 12 for each of the steps 15, and these stop-levers are severally actuated by separate tabulating-key levers 7, one for each, which bear upwardly against the respective stop-levers 12, either directly, as in the case of the upper three, or through the medium of rods 16, as shown in the second and third sets of three. In Fig. 1 dotted lines indicate the terminal ends of the key-levers 7 in each range which are controlled by the one shown, each successive key-lever being made slightlyshorter than the one before it, so that each will actuate one of the stople\ ers 12. In like manner the stop-levers 12 are made of different lengths, so that each will beengaged by one only of the key-levers. The respective stop-levers 12 are formed on their under sides with notches 12, that allow free downward movement of the lever except when the lever 11 is moved (to the right in Fig. 2) by the bell-crank 10, as aforesaid, when a horizontal lug or arm 11 on said lever 11 comes under a projection or shoulder 12 on all the levers 12 and prevents depression of said levers. Springs 7 serve to return the keylevers 7 to normal position. A release-lever 18 is fulcrumed to the fixed frame at 18 and connected to a cross-bar 18, which extends over all the levers 12, so that when any one of said levers is moved one end of the said release-lever will be raised and the opposite end will bear down on a pin 19, connected with escape mechanism (not shown) to effect the release of the carriage from the escapement or step-by-step feeding mechanism, which may be of usual or well-known form. I prefer to provide means for easing off the shock due to arrest of the spring-drum by the stop-levers 12, and for this purpose I mount the pivotshaft 13 in a slot-bearing 20 on the fixed frame part in such manner that it can slide parallel to the motion of the carriage, and a spring 21 is provided which draws the said shaft toward the spring-drum.

The operation of the device isas follows: Normally all of the stop-controlling devices 4 are in depressed position, as indicated for the device at the left in Fig. 2, so that in the travel of the carriage the stop-controlling devices 4 will successively strike and depress the cam device 10 and through the lever 10 will operate the lever 11 and hold the lug or arm 11 thereon under the shoulder 12 of all the levers 12, thereby preventing operation of any of the stop-levers 12. If the operator desires to write in any particular column, he moves the corresponding column-stop-controlling device 4 to a position wherein it will be free of the cam device 10, and when in the travel of the carriage this column-stop comes opposite the cam device 10 said cam device being free will allow the lever 11 to remain out of cooperative relation with the shoulder 12" on stop-levers 12, thereby leaving the said stoplevers free to be depressed. The lever 11 is restored to normal position by a suitable spring and by its pressure against the lower end of the bell-crank lever 10 restores this to normal position when released. Assuming that the operator has depressed the proper tabulating-key 7 for the denomination he desires to write, the corresponding stop-lever 12 will fallagainst the spring-drum periphery, and the principal stopping means 14, which is then opposite the stop-levers, will engage with the operated stop-lever 12 by that one of its respective stops which corresponds to said stop-lever. In such engagement the arresting of the carriage is not sudden, but is taken up by the spring 21, the carriage being finally arrested by the shaft 13 reaching the other end of the pivot-slot 20.

The stop-lugs 4 retain by friction either position in which they are adjusted. The distance to which they may be pulled out into operative position beinglimited, theyoffer un yielding resistance to the stop-key device used in conjunction therewith.

From the above description it will be apparent that the oscillating stop-levers 12, operating in conjunction with the oblique sets of teeth- 15' on the feed-drum, constitute rotatable denominational stops which are rotated to bring them to different denominational positions, and the key-levers 7 constitute means for locating said denominational stops at different denominational positions, also that the adjustable dogs 4, bell-crank levers 10, and levers 11, in combination with the stop-levers 12, constitute tabulating-stops cooperating with the denominational stops, for the reason that the manipulation of the several equidistant adjustable dogs 4 locates the column in which the printing is to be done.
