ANDREW -ammo AND WILLIAM sumo, or nosrox, imsstcnossrrsy' LINE-FINDER FOR STENO'GRAPHERS USE'v IZFIZCITE :CATION Application filed July 24, 1835.

To all whom) it may concern:

Be it known that we, ANDREW Nnmo and YVILLIAM NIMMO, citizens of Great Britain, residing at Boston, in the county of SutTolk and State of Massachusetts, have invented a Line-Finder, of which the following is a specification.

This invention relates to improvements in line-finders for steuographers, and it is carried out as follows, reference being had to the accompanying drawings, where- Figure 1 represents a side elevation, and Fig. 2 represents a' front=elevation, of the apparatus. Fig. 3 represents a detail view of the pedal by which the indicator is worked.

Similar Ictters refer to similar parts wherever they occur on the difi'erent parts of the drawings. v

In inakinga long-hand copy from shorthand, or vice versa, or for making any other kind of copying, it is desirable to.use a line-finder adapted to be adjusted line for line as the copying proceeds, and thus set-veto find the line copied from with the greatest ease and without loss of time. For this purpose we have constructed our invention, as follows: R- G S is a standard or support, of-any desirable form, to the upper end of which is secured the inclined plate or book-rest A, having attached to its upper end a suitable bar or clip, F, for holding the leaves of the book or manuscript to be copied from in position. Through the book-rest A is made a slot, B, in which the block B is guided and permitted to travel up and down. To the block B is attached, above the plate A, the horizontal indicator or line-finder C, as shown, and this is made to move with the block B. To that portion of block B which projects below the plate Ais hinged the pawl I, the lower end of which engages in the teeth of the ratchet-bar E, and is normally'held in contact therewith by means ofa small spring, J. (Shown in Fig. 1.) The ratchet-bar E is supported and made to slide in the guides O and 0", secured to the under side of plate A, and is normally drawn up ward to its highest position by the influence of a spring, H, secured to the upper end of ratchet-bar E, and to a projection, 0, attached to the under side of the upper end of plate A, as shown in Fig. 1. The downward motion of i ratchet-bar E is limited each time by means of forming-part of Letters Patent No. 332.410, dated December 15, 1885.

Serial No. 17233]. (No model.)

the adjustable stop K coming in contact with Y the lower guide, 0", as shown in Fig. 1. Said stop K is made adj ustablc on the ratchet-bar E, according to thehorizontal distance bejusted it-is firmly secured in place on the ratchet-bar E by means of the set-screw L, as shown in Fig. 1. To the lower end of the ratchet-bar E is attached a running over a pulley, M, that isjournaled in tween each line on the copy, and when so adcord or strap, N,

a bearing, M', securcd to the under side of on plate A relative to the lines on the copy resting on the latter, either in commencing workon a new page or during any portiouof the work, as the case may be, we employ a. thumb'piece or button, D, passing through block B, and having its lower end attached to the pawl-piece I, as'shown in Fig. 1, and thus by simply pressing on button D the lower end of pawl I is raised out of the teeth on ratchetbar B, when the block B and line finder orindicator C may be moved up or downon table or plate A to any desired desired.

The operation is as follows: After the book or manuscript has been secured to the plateA by means of clip F or other suitable fastening device, we press the button D downward, by which the pawl I is disengaged from ratchetbar E and move the block B upward, so that the indicator 0 shall come to the desired line for commencing the work. The stopK isthen secured by means of sct-screwLto the ratchetbar E at the desired distance fro'mguide 0'", equal to the distance between the successive lines on the copy. Alter one line has been copied the operator depresses treadle P, causing the ratchet-bar E to be drawn downward against the influence of spring l-I until the stop K comes inco'utact with guideO', and'during such motion of ratchet-bar E, by'ineans of theposition, as may be pawl I, the block B iscarried downward-suificiently to bring the line-finder G to the next line on the copy, after which-the operator releases his foot-pressure ou the tread-1e I, when the spring H will draw the ratchet-bar E up to its normal position,'and during such upward motion of ratchet-bar E the pawl I will pass freely by the teeth of said ratchetbar, causing the block B and line-finder C to remain in the position left; by the previous downward motion of the ratchetbar E, andso on. \Vlien the indicatorO has traveled to the lowest line on the book or manuscript copied from, a-new leaf is turned, the button I) depressed, and the block B and'indieatorC moved upward to the desired position for commencing work, and the successive operations for feeding the line-finder C downward continued, as above described.

\Vhat we wish to secure by Letters Patent and claim is 1. The herein-desci ibed line-finder, consisting of the stationary rest A. having slot-B for the movable block B, to which is attached the i in the toothed ratchet-bar E, the latter being guided in the parts 0" 0", and operated by,

means of treadle P and strap N against the influence of spring H, and provided with the adjustable stop K, as and for, the purpose setforth.

2. In a line-finder, the stationary plate A,

the block 13, movable thereon, with indicator 0 attached to it, and having pawl 1, spring J, and pressbntton D, as described, combined indicator c; said block having hinged to it; the pawl I,with spring J, and adapted to engage with the reciprocatory ratchet-bar E, for operating the bloekrB and its indicator 0, substantially as and for the purpose set "forth. v DREW .NIM'MQ' iVitnesse-s:
