wma-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent Ne. 543,112, dated' July 23, 1895.

application tiled June 28. 1894 ToaZZ/.whom it may concern:

chines, of which the following isa specificav tion, reference being had ltherein .to-the ac` companying drawings.

This invention relates to an improvement in type-writing machines; andjithas for its principal object the provision of improved means for varying the feed of the paper-carriage, so as to provide for impressions beingl made upon the paper at variously-separated points in a liri'e'instantly, instead of the necessity of a determination of the points in the line at which impressions shall be made by a repeated depressionpf the usual space lever or lkey of the machine. I aim at improvements in the devices for accomplishing this; end. I provide for the easy adjustmentto vary the points of stopping of the carriage. l simplify and lessen the number of vparts vreg quired to produce the desired result.

Other objects and advantages of the invention will hereinafter `appear and the `novel features thereof will be specifically defined by `the appended claims.'

Theinvention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form apart; of this specification, and in whicli- Y Figure 1 is a vertical section from rro'ntto reax, showing sufficient parts of the typeits application. Fig. 2 shows in plan and edge View my .improved rack-bar remoyed. Fig. 3 isa `perspective view of the parts constitu ting the invention with a portion broken away. Fig. 4 is an enlarged detail, partly in section ,and partly in elevatiomwith portions .f brokenfaway. Fig. 'isa vcrticalsection through the pivoted pawl, and Figf isv an enlarged perspective detail showin g the campertion on vthe rack-bar.

Like letters lofreference indicate like part throughout the several views.

All the parts of the machine not ,illustrated may be of any well-known form of construesinn n515325. maman.)

tion with` which the parts constituting 'the present invention will co-operate o r upon which they'may beemploye Referring now to the details of the drawings by letter, A designates the base or frame of the machine, A the carriage, and A2 the lugs thereon, which embrace' and slide upon the carriagerod 4A" in the usual manner. l

A4 is the platen, A5 the type-bars, and A64 the key-lever connec led therewith to operate the same in the ordin. ry way.

The carriage is provided with the front wheel a running on thy track a as usual and is propelled forward by he spring and chan, the latter being seen in Fig, 1 and designated bythe letter MTA' is Ls step-byj-step feed rack-bar.

B and B- are the paw'fs for engagement.,

with the rack-bar'A", the said pawis being pivotally mounted in the @snai manner and ,theone provided with thv rearwardly-projectingpin b, which serves 1n connection with the margin-regulator mechanism now to be described. v C is the column-printing lever. It is pivotally mounted at its rear ejid upon the rod` c, as shown in Fig. 1, and at a point in front of its pivot it is connected by the ligament D' 'with one end of the arm D", which is 'pivoted betweenits ends uponra pivot d on a lug' d', prcjecting from the frame, as indicated by dotted lines in Fig. 1. The o' her end of this arm is connected by the ligament 1 )2 with the inner end of the rack-bar E,Awfiich is mounted at) its ends for pivotal or rocking',r movement, ard upon this rack-bal' is adj ustably mounted 'he bcck E', in which is pivotally mounted a 'awl E?, which is adapted to .ngage the teeth v.of the rack-bar E, the pivo; e of the pawl b. ing mounted for rotation in 'the block and h pawl being fast thereon. the pivot being extended upward to form ahandle e', by which. a epawl may-be moved to' throwit ont of en- ,jagemen't with the rack-bar to shiftthe block :o stop the carriage at any desiredpoint in ts traveltu the right to leave any desired width of margin on the paper. rlheinner end [of the a'rm D carrie aforwardly-extending har F,'which may be eld thereto or integral therewith and the free end of this bar is dexoo signed to engage beneath the pin or projeetion b on the pawl B', as seen in Figs. 1, 3,

and 4. o -v G is the paper-table, and H is my special feed rack-bar, the edge of which is provided with a plurality of holes 72, into any one or more of which maybe removably inserted, as by screwing, pins or screws l1', as seen in Figa-2 and 4, so that they may be readily ze changed to varying the distance between stopping-points when desired. This bar H is provided at each end with bosses h',which are interiorly threaded and with which engage the thumb-screws H, which pass through x5 openings in the paper-table, as shown, and

thus detachably hold the rack-bar to the nn-` der side thereof. This rack-bar is b v preference arranged at aninclination relatively to .the vertical, as seen best in. Fig. 4,-in order to. zo accomplish the best results. v

I isa bracket secured on'the frame A, as seen best in Fig. 4, and upon this bracket is pivoted a pawl J on the horizontal pivot t',

held ,in the verticai portion of the bracket 2 5 and having the depending side portions j, which straddle the vertical portion of the i bracket, and the front rface of the pawl is provided with a tooth J', while beneath its rear portion is a spring 'Kras seenV best in 3o -Fig. 4, which spring ndaa' bearing upon the top of the vertical portion of the bracket.

The pintle of the inner end-of the raelnbar E is supported in this'block, and. at thisend the said rack-bar is provided with scam portion L, as seen in Fig, 3 and by dotted lines in Fig. 4.

M is the ordinary spring connected with the key1evers for retaining them normally in position.

With the'purts constructed and arranged substantially as above set forth the operation is as follows: The pinsor screws H are placed in the proper holes to give the desired space between stoppages of the machine for tabulated work, the machine being fed'along step by step in Athe ordinary manner, except wheny 'it' is desired to erploy the same for such tabulated work. By depressing the lever'C the' 1 right-hand end of the arm D' isdrawn down 5o and its other end consequently thrown up, when its bar F engages the pin b on the pawl B' and throws the latter out of engagement with the ordinary rack-bar of the machine. This depression of the lever C also rocks the rack- 5 5 bar E on its pivots and throws the same up, and the cam L is moved away from the legof the pawl J, vwhen the spring K throws the same forward, as will be readil understood from Fig. 4, so that its tooth J is projected 6o into the path of the pinsor projections H on the special rack-bar. As soon as pressure is removed `from the lever C the parte return to their normal position, and the cam portion, coming in contact with the depending leg of 6 5 the pawl J, throws the upper portion thereof back ont of the path of the projections on the rack-bar H. In Fig. 1 the parte are in the sition they assume during the ordinary use of the machine; but in Fig. 4 the lever C has been depressed andthe pawl B' thrown out of the path of the rack-bar A" and the tooth J of the pawl J into thepath of the projections on the special rack-bar. 'liiol\1;,ut2,actl ng in contact with the margin-stop E, serves to stop the movement of the carriage.

Modications in detail may be resorted to without,departing from the spirit of the invention or sacrificing any of its advantages.

What I claim as new s 1. The combination with the relatively iixed step-bystep feed rackbar,and the pawls cooperating therewith, ot a special rack-bar on the carriage independent of 'the step by step feed rack bar, a rocking pawl for cooperation f with the special raclr', a rocking rack bat' car; rying said pawl and la lever and connections for act ating said rocking pawhsnbstantiall y as sp iled. o,
