tion.

This invention relates to that class of devices which are known generally as stationindicators and which are used in passengercoaches of railways and trains for the purpose of indicating for the information of the passengers the name of the next station at which a stop is expected to be made.

My invention has for its object to produce a device of this class which shall possess superior advantages in point of simplicity, durability,and general efficiency; and with these ends in view it consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims. In the accompanying drawings I have illustrated one form of embodiment of my invention; but it is to be understood that I do not limit myself to the structural details therein set forth, inasmuch as departures from the same may be made with regard to the shape, proportion, and general assemblage of parts without departing from the scope of the in vention.

In said drawings, Figure l is a front eleva-.

tion of a device constructed in accordance with the. principles of my invention. Fig. 2 is a vertical sectional view taken on the line 2 .2 in Fig. 1. Fig. 3 is a side elevation. Fig. 4 is a transverse sectional; viewtaken on the line 4. 4. in Fig. 2. f

Corresponding parts in the several figures are indicated by similar numerals of'reference. 7 V

In the form of embodiment of my'invention illustrated in the drawings hereto annexed 1 designates a casing, which in this instance consists of side pieces 2 2, preferably made of wood and having curved upper and lower ends 3 3, and a front piece 4, which is preferably constructed of sheet metal and which is nailed or otherwise secured to the side pieces 2 2, as Well as to the curved ends 3 of the latter, the front piece 4 being thus bent to form the upper and lower end pieces 5 5, the extremities of which are bent to form flanges 6, through which nails, screws, or other fastening means for mounting the device in its proper position may be passed.

The front piece 4 is provided with a slot 7 in the face thereof, and behind this slot is arranged a cross-piece 8,-spa'cing the side pieces 2 2 of the device. The cross-piece 8 should be spaced from the front piece 4. merely sufficiently to admit of the passage of the apron 9, bearing the names of the stations, as will bepresently set forth.

The sides 2 2 of the casing are provided above and below the cross-piece 8 with bearings for shafts 10 and 11, carrying rollers 12 and 13, which are mounted securely upon said shafts, which latter extend through perforations in the side pieces which form the bearings. v The bearings may be reinforced by metal plates, such as shown at 14.,upon the inner sides of the side pieces. The roll.- ers 12 and 13 are shorter than the distance between the side pieces 2 2, and between'one of said side pieces and the adjacent ends of the rollers are interposed springs 15, coiled upon the said shafts. These springs naturally tend to force the rollers in the direction washers 17 upon the ends of theroller-shafts opposite to the ends having the coiled springs. These collars *or washers 17 are intended to serve, in conjunction with the springs 15, to create snfli'cient friction to prevent the rollershafts from being accidentally rotated. The collars or washers 17 may, as in the drawings hereto annexed, be made integral with the rollers, as may be shafts of the latter.

The ends of the roller-shafts which'by the action of the springs 15 are normally projected beyond the side pieces 2,in which they are jour naled, are provided with winding-posts or are otherwise adapted to be engaged by means of a suitable key whereby they may be rotated. Pivotally mounted upon the side of the casing through which the said roller-shafts extend is a lever 18, which is preferably made of elastic material and which may be shifted so as to press either of the roller-shafts against the tension of the spring 15, thus tensionally of the opposite side 2, where recesses 16 are. provided, which are engaged by collars or holding it against rotation by its exercise of additional tension against the tension of the spring 15,

The apron 9, which is wound upon the rollers 12 and 13, is attached at its ends to both of said rollers. Hence by winding the apron upon one of said rollers it will be unwound from the other. Printed or otherwise inscribed upon the face of the apron in letters of sufficient size to be readily observed are the names of various .stations, &c., to which it may be desired to direct the attention of the passengers.

The operation of this invention will be readily understood. The device is set by the conductor or porter of the train immediately after leaving each station by simply turning the shaft of the appropriate roller by means of a key with which the operator is provided. While the roller is being. turned an inward pressure should be exerted upon it by means of the key, thereby avoiding undue friction. The spring-lever 18 is normally in engagement with the projecting end of the shaft of the roller from which the apron is being unwound.

claim 1. In a station-indicator, a casing having a slot and provided with recesses formed interiorly in one of the sides thereof, a crosspiece disposed transversely behind said slot, apron-carrying rollers journaled in the sides of the casing above and below said crosspiece, tension-springs coiled upon one end of each roller-shaft betweenthe roller and the adjacent side of the casing, and friction-collars upon the roller-shafts engaging the recesses in the opposite side of the easing.

2. In a station-indicator, a casing, shafts journaled in the sides of said casing, aproncarrying rollers upon said shafts, spring means for forcing said rollers in the direction of one side of the casing through which the shafts of said rollers are thus projected, and a spring-lever mounted exterior-1y upon. the casing and adapted to engage the projecting ends of the roller-shafts.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

JOHN JACKSON.
