TYPE-BAR CONSTRUCTION.

SPECIFICATION forming part of Letters Fatent No. 758,197, dated April 26, 1904.

Application filed April 13, 1903- To' all whom it may concern: v

' Be it known that I, FRANZ X. WAGNER, a citizen of the United States, anda resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Type-Bar Construction, of which the following is a specification.

My invention relates to the type-bars of type-writers and other machines, and has for its object, first, to enable a type-bar to be readily removed from the machine without disturbing the other type-barmand, second, to enable the distance between the pivot and the type to be accurately adjusted.

To this end my invention consists of certain features of construction and combinations of parts, as will be fully described hereinafter, and particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which Figure l'is a sectional elevation of a portion of a type-writer embodying my improvements. Fig. 2 is a plan of the type-bar. Fig.

' 3 is a cross-section on line 3 3 of Fig. 2. :Fig.

plate.

4 is a detail view of the pivot portion of the type-bar and its support, drawn upon an enlarged scale; and Fig. 5 is a partial rear elevation of the segment, showing the cover- A indicates the portion of the machine-frame to which the key-lever B is pivoted at B.

C indicates a pin-and-slot connection'be tween the key-lever and an elbow-lever C, ful crumed at C This elbow-lever has a pinand-slot connection D with a type-bar pivoted at D upon the segment E,'which also carries the type-bar guide F, extending adjacent to the point where the type strikes the platen G. The manner of actuating the typebar is immaterial to my invention.

A is a cushion for supporting the type-bars in their position of rest.

The pivot D is of angular shape and fits into slots E ofthe segment E, substantially of keyhole form-that is, said slots are widened at their inner ends, so that the pivots may turn therein; but the outer portions of the slots are Serial No. 152.297. (N0 model.)

slid therethrough in a predetermined posit-ion only, as will be obvious from Fig. 4. A coverplate H, having teeth H to close the rear ends of the keyhole-slots E, may be provided, if desired, this plate being secured to the segment E. When it is desired to remove a type-bar, the cover-plate H is removed or at least swung out ofthe way, and the elbow-lever C is lifted from its pivot O and disengaged from the typebar, whereupon the latter may be removed rearward without disturbing itsneighbors.

In order that each type may strike the platen at the same point, I so constructthe type-bar that the distance between the pivot and the type may be adjusted, and to facilitate this adjustment I provide a gage device which is practically automatic in its action. For this purpose the type-bar consists of two sections, a rear section or pivot-section D and a front section D carrying the type J. These sections have a sliding connection with each other, so that the type-bar is extensible and the distance from the pivot D to the type J may be varied. The connection may, for instance, be made by means of ascrew K, screwing into the type-section D and extending through a longitudinal slot D of the pivotsection D. To brace the type-bar, its sections may be bent to form longitudinal ribs D D, one of which fits into the other. (See So far as described the construction allows the distance between the pivot D and the type J to be varied; but a proper adjustment would require relatively considerable time and skill on the part of the operator. To facilitate the adjustment, I provide an automatic gage device which comprises a beveled pin L, arranged on the type-section D and a guideaperture F on a stationary part. Preferably the pin L is located adjacent to the type J and theguide F on the type-bar guide F.

It will be understood that when the pin L is within the guide F the type J occupies the correct position relatively to the platen Gr. The operation of this part of'my invention is as follows: At the time the type-bars are first put in the machine the two sections are roughly adjusted so that the type will be in approximately the right position. Then the screw K is somewhat loosened, so as to still hold the sections DD together in their rough adjustment, yet allow the type-section D to slide outward or inward if a push or pull is exerted on said type-section. Thereupon the type-bar is swung against the platen by depressing the key-lever B. Now by reason of the inclined or beveled shape of the pin L if said pin should not enter the guide F centrally a deflecting or wedge action will occur and the type-section D will automatically be shifted to the proper position. The screw K will then be tightened, preferably while the type-bar is in its vertical or printing position.

Various modifications may be made without departing from the nature of my invention. Thus it will be obvious that the position of the pin K and guide F may be reversed, locating the beveled pin upon a stationary part and the guide on the type-section D Instead of the pin the guide may be beveled, or both members of the gage device may be'beveled.

I claim as my invention and desire to secure by Letters Patent 1. In a type-writer or other machine, a sup.- port having keyhole-slots, a type-bar having an angular pivot arranged to enter said slots, and a movable cover-plate provided with teeth arranged to normally close the open ends of said slots.

2. In a type-writer or other machine, a pivoted type-bar, the type of which is movable toward and from the pivot, in combination with a gage device consisting of two members, one of which is stationary while the other is connected with the type-bar, to control the adjustment of the type relatively to the pivot of the type-bar.

3. In a type-writer or other machine, a pivoted type-bar, the type of which is movable toward and from the pivot, in combination with a gage device consisting of a pin member and a guide member, one of said members being stationary while the other is connected with the type-bar, said members being adapted by their engagement to control the adjustment of the type relatively to the pivot of the type-bar.

4. In a type-writer or other machine, a typebar consisting of two sections, a pivot-section and a type-section, one of said sections being provided with a groove and the other section having a laterally-projected, longitudinal lyextending rib adapted to fit intosaid groove, said section being arranged to slide in the said groove for the purpose of adjustment.

5. In a type-writer or like machine, a typebar consisting of two sections, a pivot-section and a type-section, one of said sections being provided with a groove and the other section having a laterally-projected, longitudinallyextending rib adapted to fit into said groove, said section being arranged to slide in the groove for the purpose of adjustment and means for locking the two sections together.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
