TYPE-BAR HANGER.

SPECIFICATION forming part of Letters Patent No. 744,253, dated November 17, 1903.

Application filed April 14, 1903. 'Serial'llo. 152,574. (No model.)

To all whom it may concern:

Be it known that I, CHARLES SPIRO, a citizen of the United States, residing at New York, in the county ofrNew York, State of New York, have invented certain new and useful Improvements in Type-Bar Hangers,

of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to type-bar hangers for type-writers, and particularly to a structure thereof adapted to be formed principally by machine-work,thus reducing to a minimum the hand labor required thereon and the consequent cost of production, while the finished product is rendered more efficient in use.

, Heretofore in this art it has been common to cut or saw from a bar of metal a blank from which the bracket which in connection with the pivot forms the type-bar hanger and then bore the pivoting-lugs of said bracket, which are required to be subsequently countersunk upon their inner faces, thus requiring a great deal of hand-work in the production of the article.

stamped or cut blank, which is subsequently die-pressed into shape, and an aperture of even diameter simultaneously bored through,

with lugs adapted to pass through the type-- bar and be normally secured therewith,while the pivot is journaled at the opposite ends in adjustable sockets, which are countersunk to form the bearing-points.

Other and further objects and advantages of the invention will be hereinafter set forth, and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is an elevation, with parts in section, of the type-bar in printing position; Fig. 2, an elevation of the blank from which the hanger-bracket is formed; Fig. 3, a similar view of this blank after being die-pressed; Fig. 4, a like view of the bracket in its completed condition. Fig. 5 is an elevation of the blank from which the pivot and connecting'plate are formed; Fig.

The present invention contem-' plates the formation of this bracket from a 6, a similar view of this blank when diepressed into shape; Fig. 7, an elevation of one end of the type-bar; Fig. 8, a similar view showing the pivot and connecting-plate applied thereto, and Fig. 9 is a vertical section through the assembled parts forming the hanger.

Like letters of reference refer to like parts in the several figures of the drawings.

The letter A designates a type-bar, which may be of any desired construction and is provided at its free end with a type A, adapted to cooperate with a platen A as indicated by dotted lines in Fig. 1, while the opposite end of this bar is pivotally mounted in the hanger B, secured to a fixed support B for instance, the segment of a type-writer frame. The type-bar is also provided with the usual ligament A for connection with the key-levers in the usual manner.

The bracket, which is secured to the support B is'formed from a blank of sheet metal by cutting or stamping same therefrom, and this blank is substantially of the shape shown in Fig. 2 when so out. In this figure the body B of the bracket is provided at opposite ends upon one face thereof with projecting portions 13 and upon the opposite face with a central shank-portion B The blank is then placed in a suitable die-press and the projecting portions B formed by pressure into the circular pivoting-lugs B while the shank B is pressed into a substantially curved form, as shown at B in Fig. 3, and each of the pivotingdugs is bored or drilled with an aperture B of equal diameter throughout, which drilling is performed at a single operation,

thus assuring perfect alinement of the aper" tures. The blank thus pressed is now in condition for finishing, and the only further work required is the interior threading of the lugs B to receive the bearing-screws O and the threading of the shank B to receive the holding nut G, as shown in Fig. 4., when the bracket is ready to receive the pivot. These screws 0 are provided with a central aperture 0 adapted to permit the oiling of the bearing and also to allow a passage for the egress of any grit or dirt which may work its way therein, while the innerend of each screw is countersunk, as shown at 0 so as to have a convex curved bearing-wall adapted to engage the bearing of the pivot to be hereinafter described. The pivot is formed by stamping or cutting from material a blank of sheet metal substantially of the shape shown in Fig. 5, which comprises a T-shape structure having a pivot-bar D and a lateral plate or bar D at one side of the longitudinal center of the bar, so as to bring the type-bar when connected to this extension substantially in the center of the pivot-bar. This blank is of an angular cross-section when cut, and the pivotbar D thereof is subsequently diepressed into circular cross-section, while the ends D are suitably finished to provide slightly-concaved beai'ingfaces, as shown in Figs. 6 and 9, it being noted that the connecting-plate D is still disposed at one side of the longitudinal center of the bar, so that when the lugs D are passed through the aptures A in the type-bar A and secured therein in any desired manner-for instance, by heading, as shown in Fig. 9said type-bar will lie substantially in line with the longitudinal center of the pivot-bar, while the bearings D at the ends of the pivot-bar D are seated into recesses or countersunk portions 0 of the journaling-screws C, said recesses being of greater depth than the portions D so as to allow an adjustment of the screws 0 into contact with the bearing portions D without contacting with the extreme ends of the pivot-bar.

It will be seen that by forming this hangerbracket from sheet metal by stamping the same maybe made of much less weight than heretofore, while the pivot-lugs being formed with an aperture of continuously equal diameter can be accurately drilled and the screws threaded therein, so as to produce the completed article with a minimum of handwork and at the least cost of manufacture. It will also be observed that the improved construction of pivot when used in connection with this bracket is adapted to be held in position by the adjusting-screws, and all danger of jamming or wedging the bearing is obviated by the construction of screw herein shown, while the connecting-plate of the type-bar presents an extended bearing-surface in connection therewith, so as to secure the most desirable leverage and form of connection between the hanger and the type-bar carried thereby. The angular lugs entering the recesses of similar configuration in the bar prevent any possible movement of the parts upon each other.

It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is-

1. A type-bar bracket comprising a body having lugs at opposite ends each provided with threaded apertures of equal diameter therethrough and in alinement with each other, and a central threaded shank upon the opposite face thereof from said lugs.
