IMPROVEMENT IN STATION-INDICATORS.

Specification forming part of Letters Patent No. 156,607, dated November 3, 1874 application led September 23, 1874.

To all whom it may concern:

Be it known that I, PORTER W. TAYLOR, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Advertising-Indicator; and I do hereby declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which for'n part of this specification, in Which- Figure l is a vertical section. Fig. 2 is a front view. Fig. 3 is a detailed sectional view. i

My invention has for its object to provide an improved street and station indicator especially adapted to the display of advertisements.

My invention consists in the peculiar and novel construction of parts, having reference particularly to the band on which the names of the streets or stations and advertisements are delineated.

Referring to the accompanying drawing, A represents the exterior box or frame of the device, having windows a a', through which the names of the streets or stations and advertisements are respectively observed. B shows an internal metallic frame fastened securely at the rear to the piece A', representing the side of the car." C represents a shaft mounted in the sides of the frame B, having a ratchet, G1, spur-wheel G2, and ratchet C3. The ratchet C1 and ratchet C3, the latter shown in dotted lines, are fast upon the shaftG,while the wheel C2 is loose upon said shaft. D is a lever fast upon the shaft C. o is a dog piv-V oted on the spur-wheel C2, and c1 is a springpawl engaging with ratchet G3. When the lower end of the lever D is raised by pulling upon the cord d a shoulder, c2, of the ratchet C1 engages with the dog c, causing the spurwheel U2 to be moved, giving motion to the pinion E and revolving band F. The band F, which starts from the pinionshaft I, passes in succession over the roller-shafts PI and G, terlninatin g on the shaft l. From the said shaft I starts the band K, (which may be separate from the band F or merely a continuation of the 1atter,) passing successively over the rollershafts L, M, N, and O, and winding upon the shaft P. The band F is designed to display the name of the street o r station, while the band K is intended for the reception of advertisements. When the `cord d is pulled, actuating the wheel G2, the band F will move down, bringing the name of the next street or station into view at the upper Window a, while the band K will moveupward, showing a new advertisement at the lower window a.

The advantage of this peculiar arrangement over that heretofore adopted, wherein the advertisements and names of streets or stations alternated on a single band, the former occupying the spaces between the latter, is that a movement of the band one-half the distance heretofore required will be sufficient to produce a change of street or station name and change of advertisements. In other words, when the advertisement and street or station names succeeded alternately on the band, the names of the streets occupied distances widely apart, and hence a considerable motion of the band was necessary to change from one street-name to another. By the present arrangement, however, the street-names follow one another in close succession on the band, and hence a slight throw of the lever will effect a change of the name displayed. Thepinion-shafteis sustained in a pivoted frame, R, swinging on the shaft Q, said shaft e gearing with the shaft P. by means Of the gear-wheels e p, Fig. 3. The gravity of this frame will cause the pinion e to drop out of gear with the spur-wheel C2 Whenever the dog Sis turned back, as shown in dotted lines, which may be done by means of an external handle or button. The pinion is thus thrown out of gear whenever it is desired to rewind the bands F and K upon the shaft I, which it is necessary to do at the end of the route, by which time vboth bands will have been wound upon the shafts E and P respectively. The winding is effected by applying a key to the squared end of the shaft I, which is made to project beyond the'case A for that purpose. Connected with the lever D is a pi voted arm,

T, by which, whenever said lever is raised, a

gong will be struckand an alarm sounded, thus calling attention to the change of name and advertisement.

What I claim as my invention is- 1. The combination, with the band or bands ing the pinionshaft E and shaft P geared F K Winding from the roller I upon the rollers therewith, in combination with a station-indi- E P, of the rollers H G M N, arranged subcator, substantially as described.
