STATlON-INDICATO R.

SPECIFICATION forming part of Letters Patent No. 365,736. dated June 28, 13

Application filed February 18, 1887. Serial No. 228,075.

To all whom it may concern:

Be it known that we, James W. DUFFEE and CHARLES WEsroN, of Washington Court- House, in the county of Fayette and State of Ohio, have invented, a new and Improved Station-Indicator, of which the following is a full, clear, and exact description.

Our invention relates to devices to be carried on railway-cars for indicating the names of stations and their distances apart, and has for its object to provide a simple, inexpensive, and efficient indicator of this class which is specially adapted to be placed in every car of a train, and to allow all the indicators on the train to be-connected for simultaneous operation by compressed air or other fluid under control of the engineer or operator.

The invention will first be described, and

then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding part-s in all the figures.

Figure 1 is a front view of ourimproved sta- 2 5 tion-indicator. Fig. 2 is avertical transverse sectional elevation taken on the line 00 av,Fi g. 1. Fig. 3 is a transverse section taken on the line y 3 Fig. 1. Fig. 4 is a partial longitudinal vertical sectional elevation taken on the line 22, Fig. 2. Fig. 5 is a diagram View illustrating the application of the indicators to a railway-train and the connections for operating them from a compressedair reservoir on the engine, and Fig. 6 illustrates the application 3 5 of an indicator to a street-railway car.

The ease or box A of the indicator may have any desired size and will be made with a hinged front, a, having a glass panel, a, through which the names of the stations or stopping-places of the car, and their distances apart, produced on the canvas-band B, may be seen. This band B is attached at opposite ends to two rollers,O D,on one of which the band is wound, to be unwound from it onto the other roller,

and the band passes over rollers E E, which guide it quite closely to the front of the case. (See Fig. 3 of the drawings.) The rollers G D have end flanges, c d, respectively, to guide the canvas band as it unwinds from or winds on them. The ends of the rollers are preferably fitted with metal cap-plates, those at one end (No model.)

' of the rollers having studs which are journaled in suitable bearing-plates held to the case,and the plates at the other end having sockets in which bearing-pins enter, as shown in Fig. 4, 5 5 the bearing-pin F of the roller D being fast to the roller and j ournaled in the end of the case,

so that a crank, G, may be applied to the end f of the pin which projects through the case, for turning back the canvas or rewinding it onto the roller D from the roller 0, as presently explained. A brakerod, H, held in the case A, bears on the periphery of the end capplate, (1, of theroller D to prevent turning of the rollers and the band B, except as "they are 6 5 turned by operating mechanism provided for that purpose.

At one end of the indicatorcase A there is fastened a cylinder or barrel, I, in which is placed a rod, J, having at its lower end a 7C packed piston, K, which fits the cylinder I and is adapted to fall upon a noisedeadening packing, k, fitted on a cap, L, screwed to the lower end of the cylinder, and having a hole,

Z, for the passage of compressed air to the cylinder from a pipe, M, which will be connected with a reservoir containing the air or other fluid under pressure. A cap, L, fitted to the upper end of the cylinder I, contains a noisedeadening packing, it, against which a shoul 30 der on the pistourod J strikes to limit the upward movement of the piston. The cylinder I has a side slot, 1', for passage of a series of tappets or arms held to the piston-rod, as next described. 8

A tappet, N, is pivoted to the pistonrod J, and when down to normal position projects to engage one of a series of pins, 7;, fixed to the end bearing-plate, c, on the roller 0, for turn ing the roller onequarter around as the piston- 0 red is raised, and a tappct, O, fixed to the rod J below the one N, has a shoulder-notch, 0, which acts as a stop to the roller 0 by engaging the pin it next following the pin acted on by the tappet N, and a tappet, I, fixed to the 5 rod J, has a notch which locks with the pin acted on by the tappetN when the piston-rod falls, and as shown in Fig. 2 of the drawings.

A tappet, It, pivoted to the rod J, acts, when the rod rises,to turn a cranked arm or part, s,

of a bent wire, S, which is journaled in a suitable support, T, held to the case A, and carries a tongue or clapper, a, which strikes a bell, U, held to the case, every time the pistonrod is raised, and thus serves as a signal to attract the attentionot' the passengers to the indicator for noticing the movement of the band B in the case, or rather the name of the next station or stopping-place displayed on the band. An elastic arm, a, held to the case A, and against which the wire S strikes, prevents a second contact of the tongue with the bell. The tappets N R are free to turn past the respective parts n s which they operate as the piston-rod falls.

A bent lever, V, which is fulcrumed at o to the case A, projects inward beneath the rollerlocking tappet P, and whereby when the outer end, 2:, of the lever is lowered the tappet P, and with it the piston-rod J, will be lifted far enough to allow the pins n on the roller to rotate clear of the tappet while the crank G is turned to wind the band B back onto the roller from the roller 0 at the ourney.

By reference to Fig. 5 of the drawings it wlll be seen that we purpose placing an indicator at each end of each car of a train, and connect the pipes M, leading from all the indlcators to coupled pipes W, under the cars, and these pipes WV will be connected to a reservoir,X on the locomotive engine or tender, from which the compressed air or other fluid end of the will be taken to operate all the indicators of a train-simultaneously at the will of the engineer, who opens a valve at the reservoir,admitting the fluid to the pipes.

It is obvious that as the fluid enters the cylinder I of each indicator the pressure of it on the piston K will raise it to operate the rod J for turning the band B, as above described, and an exhaust-hole, i, is provided in each cylinder I, through which the fluid may escape after the rod J is fully lifted and until the engineer closes the valve at the reservoir, which he will do promptly to avoid waste of the fluid.

Our invention may also be applied to streetrailway cars, as illustrated in Fig. 6, the pipe M then beingsubstituted by a rod, M, which passes or may pass below the car-floor and be connected with one end of alever, Y, fulcrumed to the car-platform and having-a treadle-bar, Z, which will be depressed by the driver for operating the rod J to turn the rollers and band to display the names of the successive streets or stopping-places at the face of the indicator inside the car for convenience of thepassengers, as will, readily be understood.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
