Toultwhom it may-concern:

Be it known that J0HN' am. Cincinnati, in the county of Hamilton and.

State of Ohio, have invented certain new and useful Improvements in vStation Indicators,

&c.; and I do hereby declare that the following is a full, clear, and exact description there of, which'will enable others skilled inthe art to which it appertains to make'and usethe same, reference being ha'd to the accompanying drawings and to the letters of reference marked thereon, *whichform a part of this specification.

The nature of my invention consists in the construction and arrangement of-a stationindicator, as will be hereinafter more fully set forth.

In the annexed drawing, Figure 1 is a-front View of my improved station-indicator. Fig. 2 is a cross-sction of the same through the line a: a; of Fig. 1. Fig. 3 is an enlarged side View of a part of the indicator. Figs. 4, 5, and 6 are detached views of detailed parts of the mechanism. Fig. 7 is a' front view of the indicator with the surrounding case. Fig. 8 is a section through the line 3 3 Fig. 7.

A represents a back plate, to which the entire mechanism is attached. B is an apron, upon which the names of the stations are printed, or otherwise permanently attached, at regular intervals. On one side of each of these names is affixed the number showing the number of miles from one end of the route, and at the other end of the name other numbers, showing the number of miles to the other end of the route. This apron B is attached to two rollers, O O, mounted in bearings, as hereinafter described, so as to roll up and unroll the apron first in one direction and then in the other-that is to say, while the train moves in one direction the apron is to be turned in one direction at the proper times, and when the train returns the apron will be turned in the opposite direction. At one end each roller 0 is provided with a smooth-edged metal disk, D, of larger diameter than that of the roller, and from the center of such disk projects a journal, at, which rests in a bearing, E, attached to the plate A. Between the two bearings E E are arranged two springarms, G G, which carry at their ends small rubber blocks or. rollers b b,.-thatbearv against the peripheriesof the twodisks D D, so as to holdthem by friction from turningyexcept ard, E, also secured to the plate A. On this hub isplaced loosely a pulley-, J,. which is is hooked on a hook, i, projecting from the side of the hub h. On the inner side of the pulley J is pivoted a pawl, m, actuated by a spring, n, which pawl is to engage with the ratchet-wheel H to rotate the roller. In the outer side of the pulley J is inserted a screw, 19,Which projects therefrom and strikes the standard E, forming a stop for the rotation of said pulley. The tension of the spring I within the pulley can easily be regulated by taking out the screw 10, turning the pulley one or more times forward or backward, and then inserting the screw again.

wrapped around the pulley J, so that by pulling the same the pulley will be turned on its hub nearly one revolutioii, or until stopped by the stop 10 against the other edge of the standard E, and when the tension is removed from the cord K, the spring I will return the pulley to its former position. When the pulley is thus rotated by means of the cord K, the pawl. m engages with the ratchet-Wheel H, and rotates that roller 0 a certain distance, suflicient to bring the name of the next station on the apron Bin view, and when the tension on the cord is released, and the pulley returns, the pawl slides over the ratchet-wheel without turning the roller.

When the spring-pulley J has reached its normal position, the pivoted end of the pawl m, projecting beyond the pivot, comes in contact-with a lug or stop, .9, on the plate A, whereby the pawl is lifted away from the ratchet-wheel, and the roller is only held stationary' by the friction-roller b at the opposite end. It is, of course, understood that the when; .the, operating mechanism is ,-actu at ed.- At theother end of eachroller G issecured a flange, d, and ratchet-wheel El, and fromxthe; center of said wheel projects a. journal, .a-,f which hasits bearing in a hollow hub, h, se-,, I .cured in and projecting inward'from a stand-' made-hollow,;a nd contains a coiled spring, I. One end; of this; coiled spring is fastened to; the interior of the pulley, while the otherend K is a cord or chain, attached to ands 1so.0s9

two spring-pulleys, with their pawls and ratchet-wheels for the two rollers, operate in opposite directions, so that one cord is operated when the train moves in one direction,- and the other cord while it moves in the op posite direction.

On the inner side of each pulley J is at lever L is turned on its pivot, and when the tooth passes beyond the finger a s'pring,1?, causes the hammer 0 to strike a bell, R, as shown. The finger o is pivoted on the lever L, and held by means of a spring, 20, against a pin, w, on the lever, so that the tooth t will, when the pulley is rotated by the cord, operate the lever to sound thebell; while, when. the pulley is returned by means of its spring, the finger turns on its pivot by the action of the 'tooth on it in the opposite direction. There aretwo, of these levers, fingers, and hammers, so that whichever pulley is operated the bellwill be struck. i

The plate A, with the entire mechanism as described secured thereon, is inclosed within a case, S, having suitable glass-covered openings to expose the name of the station, as well as the numbers on each side thereof.

.On a railroad-train it is intended to'have one of these indicators in each car, and the cordsoperated directly from the engine, so that' the engineer can at one time givedue notice in all the cars of the name of the next station the train is approaching. This invention may also be used on street-railroad cars, when names of. streets will be substituted for names of stations.

Having thus fully described myinvention, what I claim asnew, and desire to secure by Letters Patent, is'-- 1. The spring-pulley J, provided with projecting tooth c, in combinationwiththe pivoted lever L, carrying hammer 0, finger v, and spring-w, substantially as and for the purpose set forth. 7

2. The combination of the curtain-rollersQ with ratchet-wheels H and standards E, havin g stationary hubs h, provided with proj ect-v ing hooks -43, the hollow pulleys J, springs I, pawls m, and stops and 8, whereby the cur; tain can be operatedin both directions,fall substantially as and for the purposeset forth.

In testimony that I ,claim the foregoing as my own I aflix my signature inpresence of two witnesses. Joann. .nnnzoaj WM. B. UPPERMAN,
