STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 278,489, dated May 29, 1883,

Application filed December 2, 1892. (No model.)

To all whom it may concern:

Be it known that I, CHARLES BALL, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Station-Indicator, of which the fol? lowing is a full,elear, and exact description.

The objectof the invention is to make certain improvements in a station-imlicator, as

. hereinafter described and claimed.

casing and the mechanism-frame.

' anism of the station-indicator, is provided in names of the stationscanbe seen.

of the stations are painted, printed, or other-' its front with a hinged or sliding door, 13, provided with a glass plate, 0, through which the The names wise produced on a band or belt, I, which has its ends secured to rollers D, journaled in two end boards E, which are held in the end boards F of a frame, F, fitting within the easing or box A. Theband I passes over rollers G at the top and bottom front corners ofthe boards E. Each roller D is provided with a pinion, H, adapted to en gage with a cog-wheel, J, mounted on a shaft, K,journaled in the frame F, and provided on the outer surface of one end board F with a ratchet-wheel, L. Two hook-pawls, M, held to slide on theend board of the frame F,,engage with the teeth of the ratchet-wheel L at diametrically-opposite points. The said hook-pawls are pressed toward the edge of the ratchet-wheel by springs N surrounding them. The hookpawls extend through the box or casing A, and are connected with cords reaching to the ends of the cars. The endboards E are provided on the outer surfaces with pintles 0, which rest on angular plates S, held on the'outer surfaces of the end boards F by thumb-screws P, passing through vertical slots Q in the said plates. The end boards F are provided with recesses It, within which the pintles O are contained.

The rollers D are such a distance apart that the upper roller D. Every time the rope connected with one of the hook-pawls M is pulled the ratchet-wheel L will be rotated the distanee of one or more teeth in the direction of its arrow, and the wheel Jisrotated in the same direction, whereby the upper roller D will be rotated in the direction of its arrow. Thereby a part of the bandI is wound from the bottom roller D on the upper roller D and another name will appear. behind the glass pane C. At the end of the line or section the end boards E are lowered, so that the cog-wheel J engages with the pinion H of the bottom roller D, whereby the band I will be wound on the bottom roller D by pulling on the rope connected with the hook-pawls M. The rollers D are lowered if the train runs back over the section; but if it continues in the same direction over a new section another set of rollers D and corresponding band containing the names of the stations on the new section are placed in the casing A.

The device can be operated by a spring or springs instead of the pawl-and-ratchet mechanism shown; and notice of a change of cars and any'other information for thctravelin g public can be printed or produced on the. band I.

I am aware" that there is nothing new in the case, the arrangement of the rolls, or the mechanism by which the band or belt is operated but i What I do claim as new and of my inven" tion is-- 1. In a station-indicator, the combination, 9

tended through the casing, whereby the mech- Ioo anism may be operated from the outside, as described.

2. In a station-indicator, the combination,

with the end boards F, having recesses B, of

' 5 the movable end boards or roller-bearings E,

provided with the pintles O,the'angu1ar plates S, having vertical slots Q, and the thumbscrews P, whereby the roller-bearings E may be locked in two differentpositions, as and for the purpose specified.
