ADJUSTABLE TYPE GUIDE FOR TY PEWRITERS Filed March 26, 1952 A TTORA/E) Patented Mar. 26, 1935 ADJUSTABLE TYPE GUIDE FOR TYPEWRITERS Fritz Eibert, Munich, Germany Application March 26, 1932, Serial No. 601,407

In Germany December 29, 1931 2 Claims.

This invention relates to adjustable type guide for typewriters. The type lever is, in the course of time, worn ofi at the places where it comes into contact with the guide. In consequence of the play caused by this, the distance between consecutive letters and the straightness of the line are adversely afiected.

The present invention has theaim of overcoming this disadvantage. It has for its object an adjustable type guide, which, as a unit or with its type shanks, can be displaced in the longitudinal direction of the type body of the type lever which has been struck. Whenever the type lever is worn to the point of afiecting the typing, the type,

guide as a unit, or the type shanks, are adjusted higher or lower, i. e. in the longitudinal direction of the type body of the type lever which has been struck, so that the type lever can be guided at a place which has not been worn, without fault and without lateral displacement.

The adjustment device can be carried out in several ways. The drawing illustrates by way of an example two forms of application:

Fig. 1 shows a form of application in which the whole type body can be adjusted as a unit.

Fig. la is a lateral view of Fig. 1, partly in section.

Fig. 1b is a plan view of Fig. 1, and

Fig. 2 is a second form of application, in which a part which supports the guide shanks is adjustably arranged in the main body of the guide.

The guide it (Figs. 1 to 1b) acts, during the stroke of a type between its shanks c, as guide for the type lever 17.

If the type lever b is worn off at A, owing to repeated friction with the walls of the guide shanks 0, so that on account of the thus created play the distance between the letters and the straightness of the type line are adversely affected, .then the guide it is adjusted as a unit, inasmuch as, after the screws h are loosened, it is, with the help of the slots d adjusted vertically and/or horizontally in the longitudinal direction of the type body. After this adjustment of the guide, the type lever will not come into contact with the guide walls at the place A but at the place B, and will again be correctly guided because a new and not worn part of the lever is being guided.

According to the form of construction shown in Fig. 2, the guide 11 is held fast in the usual way by two screws h. The guide shanks 0, however, are in this case arranged on a special body i which is held in position by means of a clamp screw 9, in an undercut groove f, cut out from the front face of the guide (1. In this case therefore not the whole guide is adjusted in a longitudinal direction of the type body, but, after loosening the screw 9, the guide shanks c are adjusted with their body 2' in the guide d.

I claim:

1. An adjustable and fixable type guide for typewriters which comprises a guide capable of being fixedly and permanently mounted on a support in front of a typewriter platen, an auxiliary member carrying a pair of shanks mounted on said guide, said auxiliary member being capable of vertical adjustment, and means for fixedly se curing said auxiliary member in any adjusted position, whereby the guide shanks can be moved from a region adjacent to a worn portion of a type lever to a region adjacent to an unworn portion of the type lever thereby insuring the correct guidance of the type lever to the typewriter platen.

the typewriter platen.
