IMPROVEMENT IN STREET AND TATIONINDICATORS The Schedule referred to inthese Letters Patent and making parl: of th same.

To all whom it may concern:

Be it known that we, Gnoncn A. Jenks' and J oHN J. Fawcnrcr, of Chicago, in the county of Cook land StateA of lllinois,'have vinvented an Improved Street-Indicator and Advertiser for Street- Cars and other purposes; and we do hereby declare that the following is a full and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing and'letters marked thereon, making a full and true description, in which- Figure 1 vis an elevation of our improved streetindicator and advertiser, the face-cap being removed to give a view of the mechanism inside.

Figurer 2, a face view of the device with the faceeap in position, 'as when in use.

f Figures 3 4 are elevations of the opposite ends of' the inner frame-work, &c.

Figure 5, an enlarged `elevation of a wheel appertaining to the device, detached from the other parts.

Tile presentinvention relates to an improvement in indicating streetsin street-cars and other purposes', as showing advertisements and Its nature consists ih the novel mechanism whereby that purpose is accomplished, as the whole is hereinafter fully described.

1 A-represent a substantial case, having suitable ends, which is conveniently arranged to support the mechanism f or operating the lettered or gured belts F G, to show thelctters and figures thereon both to passengers and to the driver, as shown by openings at B C, gs. 2 and l8, the opening 2 being for the drivers use.

.lhat part of the case at A is removable from part 1 for the convenience of reaching the. mechanism -inside, and of manufacture.

Inside of that part of the case shown at A, and

fastened to the part A1, are metal end plates, K- K7, which support the rollers and other devices hereinafter named.

A large central roller, M, has bearings in thel end plates K K', and to its shaft, on one end, is fixed a wheel, T', and to the other end a ratchet-wheel N.

. The function of the wheel 1" is to rotate the roller M, which is donev by means of a bell-cord, U, passing over wheel T and through that part of the frame shown at 1, gs. 1 and 3.

The bellcord being within convenient reach of the conductor, the belts F G are readily carried over the rollers far enough at each pull of the cord U to bring the name of a street and an advertisement oppositey T', either one of said pawls being held closely tothe i ratchet-wheel h by means of a single curved spring, t y

1The rollers M H I are designed to turn in either direction, and, to accomplish that purpose, a semidisk, m, is placed ina recess in the inner side of wheel T', and it is so acted upon by an eccentric, V', iig. 5, as to throw-either pawl y on from the ratchet h, and throw the other one in by. pressing against either prong 'of the spring t p.

The eccentric is operated by a crank, V, placed outside of wheel'T, figs. l and 3.'

This arrangement for reversing Athe movement ot' the rollers isvsnch that a pull on the cord U. will give a direct forward movement to the belts E Gr, and such that, when the eccentric V is'turned by crank V, the backward movement of the wheel T', by rubber spring S, will give a backward movement to said belts.

Stopsqr, 011 wheel Tf, and ka stop, z, on plate K shown by dotted lines, iig. 1, prevent wheel T from turning too far. A

The reversing being done at the end of theline, the last /street indicated will be the rst one on the return trip.

Coil springs l H are placed inside of the rollers I H, and attachedbothto the shafts I' H'of the rollers and to the inner peripheries of the rollers, hold'the belts F G in proper position, by being wound up with the large roller, so that when the pawls gare reversed, the springs will, of themselves, roll up the belts on the small rollers andkeep them tight.

To prevent the -springs I" H' from moving the belts when the cord U is not operating them, a spring-lock,

X, is used, whose inner end catches into notches d d,

Sac., made in the periphery of a plate, C, attached to the roller, said lock passing through the end plate K.

' To loosen the catch X, cams 'W W, attached tothe outer face of wheel T', are made to operate on another eamattached to the lock, as shown in iig. 1. To the opposite end of the journal of the roller M is attached a ratchet-wheel, N, which. as the roller M 'H I, placed parallel with each and having att-ached t-o one end a bell-hamn1er, P Q, E, by

rotates, 'operates a spring 2, will be rung at the means of which a. bell, D, iig.

' same time a street is indicated.

Twobelts are. used, as shown at fig. 8, overlapping each ot-her on roller as shownat fig `s. V 1 and 2.-

Clam. .e 4 lhe arrangement and combination of the rollers 'M other, the middle roll being the largest, ratchet-wheel, N,

for ringing 'the bell D, and to the M, one belg having the names of a street-s marked thereon, and the other advertisements,

other end a wheel, T', which is-'provided with pawls y y and cam-lugs W XY, a ratchet, h, curved spring tp, a semi-disk, m, an eccentric, V', and crank V, for reversing the motion, and lngs r o', \\'hicl1'strike against a lng, s, on theeml plate K tance that the, center roll is to move, a spring-lock, Z X, and thecoil springs H I, for taking up the belt, as and for the purpose set forth.
