TYPEWRITING MACHINE.

Application filed December 23, 1922.

To all whom it may concern Be it known that I, Lnwis G. Mrnns, a citizen of the United States, residing in Freeport, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines in which provision is made for regulating the margins of the printed matter. In such machines stops are adjustably mounted on a transverse margin stop rail secured to the carriage and movable back and forth therewith, and a centrally located stop lever is adapted to be engaged by the margin stops to limit the movement of the carriage in both directions. In order that the printed matter may be at will widened, the carriage stop lever is connected to a key known as the margin release key by operating which the carriage may be released and moved to a further extent in either direction to a limited extent. Such machines are also generally equipped with a tabular rail carrying adjustable stops which are adapted at times to engage the centrally located stop lever, the mechanism being so organized that when desired the central stop lever may be so moved as to clear the usual margin stops on the margin stop rail when the carriage is moved back and forth, but which limits the movement of the carriage to the desired extent according to the location of the tabular stops. Ordinarily a machine of this class is provided with two adjustable margin stops but often it is necessary to print matter having a definite or uniform margin and also narrower matter and this involves either a separate adjustment of the end steps or the use of an intermediate stop.

According to my invention I equip a typewriting machine with a single central stop lever, two adjustable margin stops as usual and an adjustable intermediate stop, and I also employ a tabular rail equipped with adjustable stops. Means is provided whereby the central stop lever may be so held as to allow the carriage to move to the full extent limited by the end margin stops or to move from either end stop to the intermediate stop and' means is also provided whereby the central stop lever may be so Serial No. 608,722.

set that it will clear all of the margin stops, but will be engaged by the tabular stops. The mechanism is so constructed that the central stop lever may be so looked as to hold it in the position to which it is set and to at willrelease it from such position when desired.

In the accompaying drawings Figure 1 is a sectional view of portions of a typewriting machine of the Royal standard type showing my improvements applied thereto.

In Figure 1 I have shown only so much of a typewriting machine of the Royal type as is necessary to indicate how my improvements are applied thereto. Parts .of the main frame are indicatedat A. B indicates the carriage and C the platen. The carriage is equipped with a margin stop rail D and a tabular rail. E of the usual kind and mounted in the usual way. The tabular rail carries adjustable stops 0 and the margin stop rail carries adjustable gnargin stops F and G of any suitable kind and applied in the usual way. The margin rail is also equipped with an intermediate stop I'l similar in construction to the stops F and G but having its rear portion set closer to the margin rail than the stops F and G.

The central stop lever K is pivoted between its upper and lower ends at Zto a min:

- bracket L secured to the rear portion of the ill frame A. The upper portionot' thelever is properly formed and located: to engage the margin stops and the tabular stops and its.

lower portion is connected by a linkMwith the upper end of a vertical lever N pivoted at n to the frame bar 0. A spring l? carried by the bracket L bears against the lever K above its pivot and tents to hold the upper end of said lever in position to engage the end stops F and G and the intermediate stop H. Said spring P yields to permitithe' upper-end of the lever to'be set; toclear the intermediatestop and to engage the. stops F'and G or. to clear not: onlyftheintermediate stop but also the stops-F and G-ands to onlyengagethe tabular: stop; The lever N is connected by a link Q to a bell crank lever R pivoted to a frames and. the upper end .otthis lever-isengaged-by :a push rod Tfmounted to slideiandrto turn in the suppOrtL S'tr The 1 push rod'lT- carries interme diate its front and rear ends a laterallypro jeeting' pin i and the: front: end of the rod isaseoured "to across 'piece V carryingxat' opposite ends buttons 01', ogrone-ofwhmh 1s marked' rh iargin release? and theother Margin :release lock;.: The pin-t of the pushirod-extendsthrough air-angiilarslot w in a plate I secured to the support S and-1s.

adapted to move fore: and aft iandsi'dewise in saidslot; When the push: rod T-is in the: positionshown'iniFigure-fl which is. thenormal positlon for a wlde margin or usual typewriter width, the stop leverK is in the positionshown in Figure 1 and will clear the intermediate stop H and the tabular the upper portion of the lever l; forwardly to a greater extent into the path ofthe margin stop H so that the carnagrecan onl travel between thestops F and ll; Therefore, by manipulating the buttons w, '0, the stop lever la; can beset for the kind of work desired. When the push rod T is moved forward 1n the manner indicated in Figure v 1, it may be locked in this position by turning the rod until the pin 25' engages'an ol'lset part of the slot w. VVhenthe push rod is in the position shown-Kin Figure 8the pin 1 rests against the front end of the slot 2!). The rod may be unlocked from itspositiou shown in Figure '1 byturning the rod in the manner indicated and when thus-released the eentralstop "will be moved back: tothe position shownrin Figure-8 to engagethe-interme'dia-te margin stop H;

In order to make PIO\ '1Sl0!1';f01 tabular movement e lever N work I employ a key lever X pivoted at n tothe frame bar U-and-ha-ving an upwardly extending rearportion m havinga flange 00' which engages behind the lever N. The up ward movement ot'sthe lever X is limited by a stop at? andthis lever isnormally drawn upwards by a spring a. When the key lever is depressed it moves the lever N forwards against a stop Z and this forward causes the upper portion of the central stoplever K to be moved to the position shown ate in Fig. 5' to engage a tabular stop 6. lt wiil theretore,be seen that when theilever X is depressed it moves the lever: K to a greater ex tent .rearwardly, than when moved by but.-

tons 2;, or ,o. lnasmuchas itis desirable in such machines to employwhat. is known as a. palm tabular key I may connect such-a key with. the leveriN inthe manner shown in Figure'l. Thisv palm tabular key K1 is piv'-.- otally mounted at k in the machineirameand has; an upwardly: and rearwardlyex tending arm is which isrconnected by-sa link ic to. an arm n extending rearwardly and downwardly from thelever Il't; is;normallyheld in raised position by a spring By depressingeither thevkey I; orthe. key K" the stop lever K mayzbe. moved to a position to I engage the tabular; stops.

In: l i'gurea i 5- I have shown I diagrammatr cally the relation ofthe .center stop lever, or

center stop? as itis usually-:called, with the margin stops and the tabular stopsr When the centerstop is-in the position in!v dic'ated ateit will be'engaged by the right. h andlmargin' stop F and. intermediate stop H, and a transverse movement 01 th? car-1 riage will be vthus limited and a wideilettw handjmargin obtained; hen tlie;center-- stop in the position 2 the movement. of the carriage wlll-be limited by the two end stop is at e llOllQOli the stops F, and ill -willbe engaged by thecenter stop but said centerstop is engaged by the tabular stops; ln this v way as the center stop is moved to the different positions, several difierent kinds of \'vo1.'k can be produced The means shown foroperating' the/center stop is of the simplest character andop erates -1nost etlic'iently; ltwill beobserved that the center stop lever'is operated and set by a single link connection \viththe single this lever is controlled by the push rod T andbyeither of the tabular keys:

When the stops-are set-to produce work 7 with the i 'ide margin as indicated in Figure 6 at the left of the word Fa'boutTanditis marginstops F and G'and whee-the center vertical lever N and that the movement ot l change from a narrow margin to a wider one. This characteristic of the mechanism is especially useful in printing insurance policies and the like.

It is also apparent that after printing with a narrow margin the carriage may be quickly shifted to a position to print with a wide margin. For instance, referring to Figure 6, if after printing wide line XYZ it is desired to print the word about (or any other word) to commence a paragraph with a wide margin, the depression of either tabular key will permit the carriage to be quickly shifted or jumped to the proper position and when the tabular key is released and the buttons o, '21 properly set, the center stop may be positioned to do the desired work. In some cases the carriage is returned to the full length of its travel. In such cases the tabular key may be depressed and the carriage will jump to the position determined by the tabular stop, for instance. to the position 40 indicated in Figure 5. The work may then proceed and as other lines are written, the carriage when next returned will be arrested at the tabular stop instead of traveling its full range of movement, or a movement limited by the margin stops. When it is desired to change the character of the work, the margin release key a may be actuated to release the margin release lock and the center stop may be shifted to the position shown in Figure 8 to operate between the margin stops F and H. In this way a great variety of printed matter may be produced.
