TLBULAR BAR AND savor.

' To alll'wh om it may concern."

Be it known that I, Lnwrs Mrnns, a citizen of the "United States, and a resident of theborou'gh of Brooklyn, in the city of iNewYork, count of -Kings, and State of New York, have-invented certain new and useful Improvements in Tabular Bars and Stops, of which the, following is a speci-' ried' bythe bar, also act to prevent an; ment out of the slots is 'liab e .totake place,

to hold the stop against upward accidental displacement.

The present invention is an improvement upon the invention disclosed in said ess application and consists; of the following featuresp A tabular bar is provided adapted to ts: ceiveqa tabular stop 1n any letter-spaceposi- ,tion, as by means of the vertical slots previ- I ously referred to, and means'areprovided slots are spaced letter-space distances apart,

and the stops are of sheet material andprovided with a lower bifurcated end, the e .of which straddle the bar and slide'int e vertical slotsof the bar. The .walls of the slots, in additionto acting as a positioning means determining the correct'position of vthe stops in respect to a scale usuallly carateral displacement of the stops. I In practice it has,

however, beenfound that u' ward displace- 'especially afterthe stops have been in use vent accidents I for some time and after'they have become worn due to their repeated insertion-and 40 The main ob'ectof the invention is to pro a, ippward displacement of the wtabular-stop'with'respect to the bar and to T provide simple and effective means for ac-l 4s withdrawal from the tabular bar.

complishing this, pur ose. In an application ed on April 25', 1917,

. Ser; no; 164370 byjEdward B. Hess, thereisdiscloeed an inventionin the spec [of-"which the tabular bar is provided with a stops beingprovided with spr ng means, in- I ificiorm ilongitudinal channelin its upperiace, the

T ivudiially spring pressed, which roject fmmzbetween the legspfthe lower b I urcat- I ed. ndo t e vs op endi g ls t s ha n 1 into the channel substantially inde which extend lo'ngitudinally of the bar which will hold the stop against accidental displacement in any letter-space position which the stop may occupy.

Another feature of the invention resides i in having a plurality of tabular stops mounted on the bar so as to be individually removable, together with means for collec-z tively holding said stops against accidental dis lacement. I i

n the specific nform in which the inventive idea is clothed in the present application the longitudinally extending member is re erably seatedin a channel in the tabu or bar, and this channel is referablv located in one of the side faces 0 the bar and cuts across the teeth'of the vertical slots.

Inv this way the longitudinal memberv serves, by engagin with a suitable notch in one of the stradd ing legs ofv the stop, to hold a stop in any position on the her, or to hold a number of stops collectively, at the same time en so desired.

' In order to permit one end or portion of said longitudinal member to yiel inwilrdiy ent of the remainder of said member, y

j blyjmake'use of a plurality'of springs, and

- are i preference arched these sprin if), e suita le means for. reventsprings and 'ingtheir lateral displacement. The epth'of the channel is in the form here disclosed greater than the cross-section of the longi-l tudinal member, so "that this member may assume anoblique position under the influence'of the springs and u uni prequre exerted against these sprin tiller:

q i end suitable means a d 1o v tion and s owlnga tabular stop in position.

' Fig. 2 is a top plan view of the same,

preventing undue outward displacement of the said'member. In order .to facilitate the engagement and disengagement of the longitudinal member with the notches of the stops, these notches "are by preference cut so as to have beveled faces sloping in opposite directions.

The main o y of the tabular'bar 7 is rovided with vertical slots 13 in its side aces, which slots are s aced letter-distances apart and are proper y; related to a scale indication on the u per face of the bar 7 as shown in Fig. 1. xtending longitudinally of the bar is a channel 14 opening into one of the side faces of the bar and cutting. acrossthe vertical slots as shown.
