Edge limiting and tabulating device on typewriters and similar machines

The innovation relates to an edge delimitation and tabulation device on typewriters and similar machines, in which the tabs for the margins and for tabulation on two separate, movable ones Paper cart attached rods are arranged.

At Randbegrer.zungi-! 'Betw. Typewriter tabs it is necessary that the associated lietötigungsgestänge Is designed to save space. ura it especially in power-driven To be able to accommodate typewriters of compact design and to ensure simple and reliable operation.

With the known typewriters, be it with only one Rider bar or with two separate bars for the margin stopper and tabulator tab, are used to limit the margins or for solutions the edge limitation and for releasing the paper cart, self-employed and separate lever gears with counter stops and corresponding buttons.

In such constructions, different individual parts make up a considerable amount of effort, whereby the entire transmission linkage extensive, prone to failure and consequently also expensive

will. As a result of the relatively large space requirements, the placement in typewriters of compact design is often associated with insurmountable difficulties.

In order to avoid the disadvantages mentioned / the innovation is based on the task of creating a simple and space-saving edge delimitation and Tabulation device with margin and tabulation tabs arranged on two separate rods. to accomplish.

The object is achieved according to the invention in that a adjustable rider stop member is provided, which in seider one position serves as a counter-stop for the margin stop, in its other position the tab is brought into the path as a tab stop and in its third position it enables the margin to be released. In a further development of the device according to the innovation the rider stop member is held in its basic position by a spring acting in the longitudinal direction and a spring acting in the vertical direction.

In order to have the opportunity to go about the beginning or in case of need To write out the end of the line length determined by means of the margin stops, the innovation contains a further feature, that is consists in that a push rod acting vertically on the rider stop member is provided for the edge solution, one with the edge release has the stop member cooperating inclined run-up surface.

Further details of the innovation can be found in the description of the Drawing of an exemplary embodiment. Show it:

The writing carriage of a typewriter, not shown, carries sins Zchnstc2f: ge 1 sit edge plates 2 _; 2 «» «« 4 another rack 3 on which any number of tabs 4 can be set.

Horizontally in the machine frame, not shown, and across to Direction of carriage movement is a rider stop member 5 is arranged, which is movable in the longitudinal and vertical directions and both for the margin stops 2a, as well as for the tab 4 as a stop can serve. At its end facing the rider bars 1, 3 this stop member 5 has an upwardly angled tab 6, which in the basic position of the stop member 5 in the movement path the margin stop 2, 2a is. The leadership of the impact link 5 in The longitudinal direction is ensured by an elongated hole 7 provided in the same, in which a fixedly arranged guide bolt borders. A helical compression spring, which presses the stop member 5 upwards, is slipped onto this guide bolt 8. In an im Stop member 5 in the vicinity of the angled eyelet 10 is provided a tension spring 11 is suspended, the other end of which is anchored in the machine frame, and the stop member 5 is on the right in the longitudinal direction strives to pull. The connection member is thus held in its base by the interaction of the two springs 9 and 11, d. i. with the flap 6 between the two edge plates 2, 2a. A pull rod 12, which connects the stop member to a tab key (not shown), is articulated on the opposite side of the stop member 5 from the angled tab 6.

During normal writing, the stop member 5 is used to with its angled flap 6 to stop the writing carriage in its position set by the start or end margin plate.

For tabulating the writing carriage in the optionally by setting the rider 4 on the rack 3 prepared positions, the movement of the writing carriage is activated by pressing down the tab key triggered in a manner not described in detail. At the same time, the stop member 5 is counteracted by the pull rod 12 the spring 11 pulled to the left by the length of the elongated hole 7, so that the flap 6 of the stop member 5 in the path of the on the Rack 3 in action tab 4 is coming «

After releasing the tab key, the Ar returns. ? d 5 sit in its output by the action of the tension spring Ί1. OK and the car is opened in a known manner by the escapement.

In order to be able to use the typewriter during normal writing, over the through the Margin stop 2, 2a to be able to move limited line beginning or line end is above the stop member 5 and in A push rod 13, which has a beveled contact surface 14, is arranged transversely to the same. If an edge release button (not shown) connected to the push rod 13 is now actuated, the rod moves 13 in the direction of the arrow I and with the inclined surface 14, it presses the stop member 5 against the force of the spring 9 and partly also the spring 11 down (arrow direction II), so that the flap 6 from reaches the area of the rider's track and thus enables free movement beyond the limit. In addition, the push rod 13 can also be actuated by the margin release key when tabulating when individually set tabs are to be skipped. Thus, the edge release function of the device is also when Tabulation exploited.

The device according to the innovation makes it possible that a single • rider stop member accomplishes three different functions,

so that separate transmission rods are no longer required. This is not only one in terms of production and assembly Simplification achieved, but also significantly reduced the susceptibility of the device to failure.
