' TYPE-WRITER.

Specification of Letters Patent.

Patented Nov. 28, 1916.

To all ic/wm 1'2 may conccrn:

Be it known that I. ALVAII C. RonnUcK. a citizen of the I nited States. residing at \Yoodstock. in the county of Mcl-Ienry and State of Illinois. have invented certain new and useful Improvements in Type-\Vriters. of which the following is a specification.

This invention relates more particularly to the type-bar guide and the means for locating the relationship between the carriage or platen and the printing point of the machine.

The principal object of the invention is to. provide new and improved means for guiding the type-bars to the printing point and for providing improved facilities for locating the position of the sheet to be printed with respect to the printing point of the sheet,

For the attainment of these ends and the accomplislunent of other new and useful objects. as will appear. the invention consists in the features of novelty in the con-- struction. combination and arrangement of the several parts generally shown in the accom mnying drawing and described in the specification but more particularly pointed out in the appended claims.

In the accompanying drawing. Figure 1 is a view of a portion of a typewriter illustrating my invention as applied. showing a.

typebar in dotted outline: Fig. 2 is a side view of the same: Fig. I is a top view. and Fig. 4 is an enlarged perspective view of the typebar guide proper.

To provide for a perfect alinement it is necessary not only that the typ bar guide proper he possessed of a certain resiliency but also that means he provided for bodily shifting the printing point in a lateraldirection. It is also desirable to provide the best possible means fol locating the line of printing when shifting paper in the platen to match a line already printed or begun, as for example. making additions or insertions. The present invention is particularly designed and intended to accomplish these results. I

In the drawing a type-bar segment 6 is shown to which a type-bar guide 7 is secured. This type-bar guide comprises a guide proper and is formed with a peephole 8 preferably circular in form with pointers 9 diametrically opposite at the top Supported by the type-writer carriage (not shown) is a platen 10 and a carriage scale 11. The carriage scale is visible from the front of the machine through the peep-hole 8, the pointers i cooperating with the scale to indicate the position of the carriage and the platen 10 with respect to the type-bar guide proper.

The type-bar guide proper comprises a notch. 1'2 in the upper edge of the type-bar guide 7 of greater width than the width of the type-bars. The type-bar guide ispreferably constructed of a single sheet or piece of material so that it is stamped from sheet material and formed with a forming die. Extending laterally from the sides of the notch 12 are portions 13 which are bent first substantially at right angles to the plane of the sheet of material and then are rounded in ardly toward each other forming a curved striking surface l-t'with the extremities disposed in the notch 12. the sides of the ends being substantially parallel. spaced from each other and spaced from the sides of the notch to permit a movement of the extremities in either direction in the notch. These extremities.- however. are of resilient -material and tend to separate at the ends. In order to accurately define the opening between the ends. an adjusting screw 15 is provided for each of the oppositely extending portions 13. These screws are threaded through the portion at right angles to the plane of the guide member so that the extremity of the screw bears against the portion at a distance from the end thereof which is in the notch. The object of this is to permit a certain resiliency of the extremities of the guide portions proper and also to provide means for adjusting them.

With this adjustment it is obvious that the extremities of the portions 13 may be adjusted with respect to each other and may also be moved to shift the guiding surface to one side or the other. thus furnishing an adjustment to compensate for any inaccuracies in the manufacture of a part and to make it possible to have the type strike centrally with the segment 6. In order to hold the adjusting screws 15 in any adjusted position locknuts 16 are provided.

Secured to the type-bar guide are line finders 17 formed of resilient or flexible ma teriaL'one on each side of the guide proper, the upper edges of which accurately define the printing line. The position of the printing point with respect to the printing line is shown more clearly in Fig. 2, in which a type-bar 18 is shown in dotted outline with one of its types 19 located on the line defined by the line finders 17, Vith these line finders it is possible to locate the printing line more quickly when shifting paper in the platen to match a line already begun, as for example, when making insertions or additions. This line finder cooperates with the peep-hole sight and the carriage scale 11 for more accurately and quickly locating the relationship between the platen and the printing pointof the machine.

rounded inwardly with the ends of said 1301' V tions disposed in the notch. to form a guide proper.

3. In a typewriter, a type-bar guide composed of a single piece of resilient sheet material having a notch in the .upper edge thereof wider than the type-bar, with portions extending oppositely from the sides of the notch adapted to be bent out of the plane of the material and to be rounded inwardly with the ends thereof disposed and freely movable laterally in the notch, the said opposite ends in the notch being substantially parallel and the notch being of sufiicient width to permit the lateral movement of both of the saidends in the notch.

4. In a typewriter, a type-bar guide comprising a member with a notch in the upper edge thereof, and resilient members formed as a continuation of the sides of the notch bent outwardly and rounded toward each other and inwardly with resilient extremi ties substantially parallel, spaced apart and spaced from the sides of the notch, and a single adjusting device for'each resilient extremity to vary the position of the extremity in the notch.

In a typewriter, a type-bar guide comprising a member having an opening and resilient portions extending oppositely from the sides of the opening .bent first at right angles and then rounded inwardly toward each other until the extremities are disposed in the opening, the sides of the extremities being substantially parallel with each other. spaced apart and spaced from the sides of the opening, the resiliency of the said portions tending to separate them at the extremities, and an adjusting screw inserted through the right angled portion of each member with the end of the screw bearing against the oppositely extending member adjacent the end to vary the positions of the parallel ends in the opening.
