To all whom 'it may concern.-

Be it known that I, Culturas E. KELLEY, a citizen of the United States, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, ol' which the following is a s eciiication.

his invention relates to the tabulating mechanisms of tvpewriting and other machines, and particularly to thc adjustable stops usually empio Ted for locating the columns on the typen-ritten page.

In the Underwood typewriting machine, as heretofore constructed, a column sto rack has been mounted upon the machine aine, and the column stops have been independently adjustable along the same. The column stops have been loosely fitted upon a cylindrical rod to enable them to turn into and out of engagement. with the rack. Each sto has been held in engagement with the racl; by means of a spring-pressed ha ll muuu ted on the stop and ada ted to tit in the long groove cut along the cy indrical rod. A companion groove has been provnlcd to enable the spring-pressed ball to hold the stop out of engagement with the rack.

Owing largely to the bindingr ctl'cct of the stop upon the rod that has been produced b the s ring detent, it has been found ditlicu t to alFust the stops easily to the exact posi tion i esired, that is to say, to bring the stop tooth exactly in register with the notch in the rack.

One of the objects ol' my invention is to overcome this trouble and to render it easy to adjust the stop thc minute distances that are sometimes necessary to secure the exact register before turnimr the stop into eixgagement with thc rack. lo this end, l provide a sprin f-prcsscd detent in the form oi' a lever. upon t ie end of which is lor-:ned n knob or lmll to engage the groove in the rml: and this lever is 'formed with n handle which is adjacent tu another handle also formed upon the stop, so that; by pressingr thc hnndlcs toward cach other, the detcnl is cntirclv released. nud binding action between the slop und thc rod is avoided. and hcncc thc stop muy bc udjustcd as little or :is much as desired, und with the greatest freedom und accuracy.

On said nnichinc, the column stop.- have been formed with eycs to lit upon `said rod and have been permanently attached thereto. lt has been found impracticable to add one or more column stops to the machine when occasion has arisen, since the rod is usually secured by its ends between two arms forming the ends of the closed frame.

Another of the objects of myinvention is to avoid this dillculty and render it practicable to take o' and re luce at will column stops of the kind descri ied. To this end, I reduce the column stop rod near one end, preferably by cutting recesses or flats there- 1n, and l cut away suflicient of the e e of the column stop to enable it to slip ofi iiom the reduced portion of the rod.

In the accompanying drawings, Fi ure 1 is a rear elevation showing suflicient o an Underwood typewriting machine to illustrate my improvements, a single column stop being shoim in workino position. Fig. 2 is a sectional elevation o arts seen at Fig. 1. Fig. 3 is a. sectional e evation of a column stop and rod with the detent released from the rod. Fig. 4 is a view similar to Fi 2, but showing the column stop swung ack and held in a position of disuse. Fig. 5 is a. sectional elevation of a column stop. Fig. 6 is a pers ective view illustratin r the manner of detac ling or attaching a colhmn stop to the rod. Fig. 7 is a front elevation of a. column stop in working osition.

In the Underwoo( typewriting machine, the carriage stop, which is indicated at l, is adapted to abut against a column stop 2, one or more of which may be mounted upon a cylindrical rofl 3 and rotatable thereon into and out. of engagementwith the tooth of the rack 4. Bot-h the rack and the rod are fixed at their ends to arms 5. The latter are also connected by a bar or shaft 6, the whole forming a frame adapted to rock forwardly and backwardly upon pivots to bring the column stop 2 into and out of engagement with the carriage stop l. The stop has a cylindrical eye 8 to lit upon the rod 3 snugly, but so us to slide and turn freely thereon. A lever l? pivotcd at lll to the column sto is l. 'l'orlncd nl its inner end with u knob or bal l1 .l to engage u groove l. lol-mcd longitudinally i in the rod Ll. lo hold the lccth lil on said sto in engagement with thc. teeth 14 of the rac *i bnr. A handle l5 is formed upon the lever, aand a spruitr 16 secured uion the column 'top engages the lult ol` san handle t-o hold thc knob 11 yicldingly in engagement with the groove l2. A single screw 17 may secure sto the handle 15 is gras ed simultaneously i Wit the handle 21 forme A .1; stop 22 adjacent to the handle 15, and the nandles are pressed towards ea'cli other, Fig. 3,the lever 9 bein thereby caused to swing up to release the co umn stop from the groove 12, 'whereupon the stop is rotated backwardly about the rod 3 to clear the teeth 13 from therack, and the stop is `tlien adjusted to the ri lit or left at Fig. 1, as far as desired, the fina minute. adjustment beinv readil effected to bring the teeth 13l into re ister wit the rack teeth 14 to erinit the co umn stop to be turned forwar( ly to workin f position.. Near the left hand end of the ro( 3, Fig. 1, I fonn cutawa s 23 to reduce the bar substantially in thickness; and in the eye of the column stop l form a slot 24 to change the eye from a closed eye to an open eye, the slot being of suoli width that it wil ass freely over the reduced portion of the roc at 23, so that the column stop may be readily' withdrawn fron: or put back upon the rodat Fig. 6. Thus more stops may be added as required from time-'to'tinieg or superfluous stops may be withdrawn. Variations maybe resorted to within the scope of the invention, and portions of the inrroveinents may beused without others. aving thus described my invention, I claim: Y
