Be it known that I, HARVEY A. Moran, a cltlzen of the United States, residing at Syra cuse, in the county of Onondaga and State of and securely hold t New York, haveinvented a new and useful Improvement in Securing Means for the Hangers of Type-Writing Machines, of which the following is a specification.

This invention relates more particularly to securing means for thetype-bar hangers or bearings of type-writing machines 1n which the hangers or bearings are separately secured to and adjustable on or removable from their support or segment.

The object of this invention is to provide simple and desirable securing means for the hangers or bearings constructed. to rigidly hangers in correct position.and to enable any desired hanger or sectional'plan of the segment, hangers,

out disturbing hangers to be adjusted or removed and replaced with great ease and rapidity and withthe neighboring or other hangers. 1

In the accompanying drawings, Fi ure 1 is afragmentary'sectional elevation in e1 1, Fig. 3, of a type-bar action provided with securing means for thetype-bar han er or hearing embodying the "invention. Fig.2 is a fragmentary sectional elevation thereof, on an enlarged scale, in line 2 2, Fig. 3. Fig. 3 is a front elevation, partly in section, of the segment, showing a portion only of the hangers in plac'ethereon. Fig. 4 is a fragmentaryi an the securing means in line 4 4, Fig. 3. Fig. 5 is a similar sectional plan, on an enlarged scale, in line-5 5, Fig. 3. Figs. 6 and 7 are sectional elevations similar, respectively, to Figs. 2 and 1, showing slightly-modified constructions. f

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

- The drawings-illustrate the ap lication of the hanger securing means to a Ont-strike type-writing machine in which the type-bars after termed hangers tion illustrated the support or segment consists of acurved bar arranged in a vertical lane below theplaten. the position of which is indicated by the circle c; but the support could be of other form and arrangement. vThe hangers and the pivotal connections or bearmgs between the same and the typebars may be of any usual or desired construction, exce t that the parts or shanks b oft-he hangers, fiy which they are attached to the segmenhare preferably straight and of uniform width and thickness throughout. The segment or support is provided on one side 'with slots radial to the printing-point on the platen, in which slots the shanks of the hangers are seated and held in the exact radial position necessary for the type-bars pivoted thereto to strike the platen at the printingpoint, but in which the hangers can be adj uste'd lengthwise, as may be necessary to' obtain and preserve a proper alinement of the printing. In the construction considered prefer able and shown in Figs. 1' to 5 the hangers are arran ed at the front of the segment in such slots formed in flanges or ribs projecting forwardly from the upper and lower edges of the segment.

E represents a clam ing-plate which is secured to the segment by devices, preferably screws F, located between the hangers, and

which bears against the projecting edges of In the constructhe shanks or attaching parts of the hangers to hold them in the se ment -slots. The clampinglate is thin an more or less flexible or resi ient and is preferably curved similarly to the segment, and the screws F, which pass through holes in the clamping-plate and enter threaded holes in the segment, are referably arranged in two rows in staggers order with one screw between each two han ers. By this arrangement the shank of eac hanger is located between two screws, and

screws with large heads can be used in a compact close arran ement of the hangers and still leave ample c earance between the screwheads. When the screws are tightened up, the hangers are clamped between the clam ing-plate and the segment and are held firm y in the segmental slots. By loosening the two screws at the opposite sides of a hanger the pressure of the clamping-plate thereon is relieved, and the hanger can be adjusted lengthwise in its slot or removed therefrom.

. be a matter of ad directly .turn them in their holes enough to relieve the pressure of the clamping plate on the hanger. is a great advantage, and much time is saved, because owing to the location of the segment in the machine it would ordinarily screw. once removed except with a speciallyconstru'cted-to ol; Another advantage of the clamping-plate resides in the fact that the head's-or the screws bear thereon instead of against the hangers, and therefore thefiiange'rs cannot be shifted in tightening up the screws by the frictional engagement of the screw-heads therewith.

- Thede'scribed securing means for the hang- "(are is not restricted to use in connection with of the segment, and Fig. 7 ment of the hangers B .any particular construction and arrangement of the hangers and segment, as before stated,

nor with any particular construction of actuating' meansfor the type-bars. For instance, Figs. 1 to 5 show the hangers arranged at the front side of the segment and the actuatinglevers G for the type-bars locatedin front of the segment, while Fig. 6 illustrates the arran ement of the hangers B at the rear side shows an arrangeat the front side of the segment and the operating levers or devices 1 for the type-bars in rear of the segment.

great difficulty to replace a I claim as myinventibn- 1. In a type-writing machine, the combination of a segment having a radial slot, a hanger adapted to be inserted lengthwise into said slot, at clamping-plate bearing upon said hanger and holding the same frictionally in said slot, and fastening devices securing the clamping-plate to said segment on opposite sides of said slot, substantially as set forth.

2. In a type-writing machine, the combination of a segment having radial slots, a series of hangers adapted to be inserted lengthwise into said slots, 21 clainping plate extending over said hangers and bearing upon the same and holding the samefrictionally in said slots, and fastening devices securing the clamping-plate to said segment, substantially as set forth.

3. The combination in a type-writing machine, of a segment havingradial slots, at series of langers seated in the slots, a flexible clampingeplate arranged over the hangers and having screw-holes, and screws passing through said holes between the adjacent hangers into the segment to clamp the plate against the hangers on the segment, substantially as set forth.

4. The combination in a type-writing machine, of a segment having radial slots, a series of hangers adjustably seated in the slots, a clamping-plate having holes for two rows ofscrews, the holes in one row alternating with those in the other row, and two screws for each hanger passing through said holes in the clamping-plate at opposite sides of the hanger, substantially as set forth.
