CONTROLLING MECHANISM FOR THE CARRIAGES OF TYPE-WRITING MACHINES.'

Specification of Letters Patent. v Patented Jan. 31, 1911.

Application led anuary 9, 1907. Serial No. 351,461.

le i 4known that I, JEROME B. Simon, a citizen of the. United States,l residing at Derby, New Haven county, `Connecticut,

have invented certain new and useful Improveniente in Controlling Mechanism for the Carriages of Type-Writing Machines, of which the following is a specification.

My invention relates to means for enabling the ready-control of the carriages of typeivriting\machines, i referably by mechanism adjacent to the ey-board, for stop ping their; in either or both directions of their movement-#Whether to limit their point of starting or their point (if-stopping#- so that for example, the operator may readily change the length oi` the position of beginning or endingof the line of writing.'

To this end, m'y invention comprises 4margin stops on the carriage, adjustable in the direction ofthe cai'riage movement and preferably plural in number at both ends ofthe carriage, and a stop or stops carried by the machine frame and controlled by a key or keys adjacent to the key-board of the inavchine to be brought readily intovor out of en'- gagen'ient with said stops or certain of them.

Preferably, 'as'shoivn in the drawings accompanying and forming part of this speciiicatioii, a single stop on the mac ine frame, cont-rolled by a rocking,` two-keyed shaft,

`may be placed in either of two positions-in one of which' it engages, in each direction of movement oi the carriage, a marginal stop for limiting the length of the printing line' to less than normal and in the other of which it engages in each direction of movement of the carriage a marginal stop for the norma-l line length. v Insaid drawings I have illustrated only so much ofa ltypewriting ma-' chinees is necessary for an understanding of the invention, and-it will be understood that the invention maybe a plied to various formsof typewriting machines and that the application to the form-here shown is merely illustrative. V

Figure 1 is a plan view of parts of the carriage-contr`olling mechanism of a typewrit- 6, fixed to and ing machine. Fig. 2 is aufroynt elevation ofparts of said mechanism. Fig. 3 is a sectional elevation,` 4looking from the righthand side ofthe machine, of theparts'shown in Figs. `1 and 2. Fig. 4 is a plan View of the controlling rock-shaft and its keys.. -Q 4 Parts of the stationary frame of themachine are indicated at 1. j ,r

At 2 shown one of the guide rails fixed to the machine frame and grooved longitudinally mits-upper surface to receive the balls 3 Whereon the,4 carriage travels.-

" 4. is the marginal-stop rack-bar, having for the greater part of its lengththe notched or toothed upper surface for locatingand holding the marginal stops at desired jpositions. .In the instance here shown, it also constitutes one of the carriage supporting and guiding rails, being fastened atits ends to the end frame of the carriage (n ot shown) and ltraveling on the balls 3, Whereon it is held and guided by one or more rolls or wheels '5, joiirnaled to bracket onbrackets projecting up rointhe rail 2 (see Fig. 3). Adjustable upon the toothed 'bar 4 are two or more sets oi:' m rgin `stops, one set?, S, serving toregulate the extreme transverse carriage movement .tor maximum predetermined length of line, and the other set 9, 10, serving to arrest the carriage in either or both directions of movement,

optionallyat points short of the `extreme predetermined line length. 'Arranged upon tlie stationary frame of the machine, as or example, upon the rail 2, is a stop 11, which in its normal position will make contact with the terminal margin, stops 7, 8, whose bills for that purpose extend down from the carriage rail 4, substantially tothe level. of

the rail 2 on the main frame, but are adjustable to an elevated position to 4engage'- the shorter bills of the intermediate para-.

graphing vor insetting stops 9, 10, as shown in dotted lines in. Fig. 2. Forthe purpose adjusting the stop 11, itV may, as here-shown, be carried upon the inner end of an .arm-12.,

fpivoted at 1 3 to the rail 2,-the stop 11 being'4 so arranged as to occupy the center of mo,-

enoug tion of the carriage so as to allow the limiting of the line length on each side to any desired extent.

. The inner end of the arm 12'has a jaw engaging1 a stop screw 14, the jaw being highl the stop from the position shown in the full lines to that shown in the dotted lines in Fig. 2. For actuating the stop the arm 12 may have va projection `15 engaged onits upper and lower sides respectively by ajaw formed of the lever arm 16 and spring arni 17 fastened by pin 19 to lever 18, Which is' pivoted at 19'1'to the rail 2 and actuated 'by a rocking arm 20 engaging by an anti-fric tion roller 20?- on a pin 20b at its upper end in a cam slot 21 in the right han'd end of lever 1S. The purpose of having arm 17 as a spring arm is to press the jaw of arm 12 by means of projection 15 yieldingly against stop screw 14, which aidsthe softness of the touch when key 26 is operated, and causes stop 11 toyield when stop 9 passes it from the right to the left, and stop 10 from the left to the right. A. spring 22 fixed to the 'machine frame and engaging apin 23 ou the arm 20, holds the latter in either-extreme p0 sition. The arm '20 is fixed to the rear end of the rock shaft 24 (see Figs.` 3 ande) which is mounteduponthe machine frameand projects forward, as shown, through the front plateof the machine Where itis pro vided preferably With two keys 25, 26 on opposite sides of-its axis and serving -to'rock it in either direction. It will be seen that when the key 25, marked Out is pressed down, the vertical arm A20 is thrown to the left,ioscillating the 'lever 18 andplacing the stopl 11` in the position-shownin lfull'lines,

Wheresit will' engage only the terminal stop 7,18; 1ut when thekey 26, marked In is presseddoyvn, the armQO-'moving-in the opposite -direct1on,f wil1 'throwthe stop 11 up to the position-shown indotted lines, whereat'itwill engage'the intermediate lstops 9,

.1Q; By adjusting-the terminal and .intermediate stops 'to the extreme line, length and to the intermediate paragraphing or insetting lengths 'of line, and then operating'the Vkeys 25, 26, itfwill be lseen that'. the line length can be changed during the operation lof the machine' directlyfrom the key-board and`A to any', desired extent. and with any required frequency? The intermediate, orone of the terminal; stops, may as4 shown, also' carryv the 'bell tripping and'line lock arm 2;

I The'relation of this to the carriage operating and controlling mechanism-is .indicated in` Eig, 1, where I have shown vat 28 certain of themechan'i'sm for operating the'belland propelling the"ca'rriage, which however are not here described this invention;-

v aeth'ey vform no.4 part of It Willibe noticed that. therear side of. the

to permit and limit the motion of' manually by handle 33.

bills of all of the margin stops are inclined tomovel over the stop 11 onl return of the carriage to position beyond them from either. direction. To hold the stops 7, 8, 9,

10, to position upon the bar 4, it .has, as shown, teeth in its upper surface, and with these' teeth engage the down-turned lips'29 on pivoted plates 30 hinged to each stop at- 31 and forced'down by spring 32, or lifted Having thusdescribed my invention, the followingis -What I claim as newr therein and Wish to, secure by Letters Patent:`
