TYPE-WRITING MACHINE; J

To all whom it may concern:

'Be it known that I, HENRY V.'MERRITT, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and'State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification. I

My invention. relates more particularly to type bars and hangers therefor.

The-main object of my invention is to provide a simple and efficient construction of hangers, and means for securing the same. I 1 v' Tothe above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices tobehereinafter described and more particularly pointed out in the appended claims. i r

In the; drawings, wherein like referencecharacters indicate corresponding parts in thevarious views;-

Figure 1 is a front to rear verticalsectional view of su fi'i-f cient number of parts of a front strike typewriting machine embodying my invention- Fig. 2 is airenlarged detail transverse sectional view of a type. bar

and hanger, the section being taken on the line xz of Fig. 3 and looking in the direction of the arrow at said line. Fig. 3 is a longitudinal sectional view -'of the same, the section being taken at right'angles to the 'po- ,sition shown in Fig.2 and orrthe line y-y in Fig. 2 and looking in the direction of the arrow at said line. Fig. 4 is a face view of a fragment of the segment and a hanger secured in position therein. r

The base 1 of the frame has corner posts 2 which support a top plate 3, that in turn supports a carriage (not shown) which travels from side to side of the machine and whose platen 4 is diagrammatically illustrated in Fig. 1. Key levers 5 are pivoted at 6 in the base of the machine and are provided with restoring springs 7. Each key lever has a sub-lever 8 pivotedthereto at 9 and the lower end portion of each sub-lever is slotted at 10 for cooperation with a fixed fulcrum rod or bar 11 beneath the key levers and extending from side to side of the machine. The upper end of each sub-lever 'carries a laterally extending headed pin 12 which enters a slot 13 at one end of a link 14, the Opposite end of said link projecting between upwardly extending ears 15 on a type bar 16 and being pivoted thereto, as indicated at 16. The forward ends of the type bars are supported upon a pad or rest 17, which receives its support from arms 18 projecting forwardly fromthe type bar Segment 19.

- as to form a substantially U-shaped housing comprising atop or roof 2] and two sides 21 that have inner parto typewriting machines and Specification of Letters Patent. 4 :B atefiited July 16, 1907 i s Application filed December 28,1903. Serial no. 186,816.

allel bearing faces; the top 21 of said recess forming primarily a dust shield. vThe top and sides of the housing prevent the admission of grit or the like 'to the bearings of the type bars, as will hereinafter more 1 clearly appear. 1

A type barhanger 22 arranged below the platen is and the side walls or bearings 22 of the hanger contact with the side walls of the cheek plates 2], as indicated 'inFig. 2. The hanger 22 has an eye 23 and the cheek plates registering holes 23 and a rivet or pivot 29 exreceived within the recess 20 inits associated typebartends through the perforations to connect together pivotallythe' type bar and hanger. j

Each hanger has a depending portion or shank 34 that has an unthreaded notch or recess at 35 which 1 provides an upper jaw 36 and a lower jaw 37. This shank 34 of eachhanger is fittedv closely within a slot 38 in the front face of tlie type .bar segment 19 and a shoulder 39 is formed on each hanger-to bear upon the top of the type bar segment, as in Fig. 1, when the hangers are in place. When a hanger is in position in its slot it may be secured by a set screw 4.1 which extends fore and aft of the machine and is supported in a threaded opening 41 in the type bar segment. The rear end of said set screw is adapted to enter the recess 35 of its associated hanger so as to bear against the straight vertical face 35 to force the stem of the hanger against the rear wall of its slot and hold the hanger .37 of each hanger is greater than the diameter of the screw 41 which, enters it, so that a slight radial adjustment of the hangers may be afforded. The screw 41 for each hanger, bearing as it does against the straight face 35, will secure the hanger in its adjusted position and bind it firmly in place. A screw 41 is provided for each hanger, and owing to the entrance of the screw between the jaws 36 and 37 the hanger is prevented from endwise displacement from the segment; Inother words the hanger cannot be removed without unscrewing the screw 41 sufliciently far to enable it to clear the lowerjaw, 37 but in order for the screw to thus clear saidjaw 37 and permit the hanger to be removed it is not necessary that said screw be entirely removed from the segment. The bearing edges 39 and 42 of each hanger are at right angles to each other and the bearing walls 40 and 42 of the segment with v which the edges cooperate are likewise at right angles to each other, so that the hangers may be readily positioned in the slots in the segment and the pivotal cen-' dered necessary, though in most cases the bearing edges 39 and. 42 and bearing walls 40 and 42 afford a proper positioning of the hangers.

The type bars 16 are preferably forged by-a series of operations into the shape or construction show'n, excepting that after the forging operation a milling cut is made at the rear or pivotal end of the: type bar to form or provide a recess 20 and produce the substantially V-shaped housing, comprising the parallel cheek and the connecting ptigtionor roof separate.

' tively slender. By thus shaping the type bar itmay be madeof light weight, and yet sufliciently strong to withstand the blows of printing.

The type bar illustrated has the usual type head at its free end and is provided at its pivotal end with two opposite walls having inner parallel ,bearing surfaces to coiiperate with the bearing of the type bar hanger. The bearing of the hanger has opposite parallel bearipg surface 22 and it is suitably carved in outline to permit the type bar to swing freely.

-Various changes may be made without departing from the spirit of my invention.

What I claim as new and desire to secure by Letters Patent, is:

1'. In atypewriting machine, the combination of a slotted segment, a type bar hanger received in a slot in said segment, said hanger having an opening therein, a set screw carried by the segment and adapted to project into the opening in the hanger and to hear at itsend against the hanger to secure it in place and to afijord a removal of the hanger when the screw is unscrewed in the segment and without entirely removing said screw, and a type bar carried by said hanger.

2.
