HENRY G-EBHABT, OF DAYTON, OHIO.

INDICATOR FOR STREETflAltS.

Specification of Letters'Patent.

Patented Feb. 13, 1912.

Application filed October 30, 1911. Serial No. 657,668.

To all whom, it may concern:

Be it known that I, HENRY GEBHART, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Indicators for Street-Oars; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a 'part of this specification.

This invention relates to new and useful improvements in indicators for street cars, to show the streets or stations to those entering cars.

The object of the invention is to provide a device of this character which is simple in construction and efficient in operation, as will be more fully described in the following specification and particularly pointed out in the claim.

Referring to the accompanying drawings: Figure 1 is a front elevation of the indicator with the casing shown in section: Fig. 2 is a vertical longitudinal section on the line aa of Fig. 3. Fig. 3 is an end elevation of the casing; Fig. 4 is a section on the line .7)b of Fig. 2, and Fig. 5 is a view showing a modified form of bearing.

Referring more particularly to the drawings, 1 represents the front of the indicator casing, which may be a portion of the car construction. The said casing front is provided with an opening 3 which receives a glass closure 4, through which the indications are observed. Extending rearwardly from said casing front are brackets 5. As shown in Fig. 5 the bearings 5 may be made in two portions, one of which, to-wit 26, is connected by a hinge 27, and has a clamping screw 28. This construction of the bearings enables the changing of indicators when a car is changed to different routes or is operated on difierent lines. The brackets 5 provide bearings for pintles 6 which extend from the end members 7 of the revolving indicator cylinder. As shown in the present case, said end members are hexagonal, each side affording space for an indication, and the same are connected by cross bars 8. The said cross bars are provided with inner depressions 9 which form pockets to receive transparent plates 10, preferably made of wheels 14 engaged by rollers 15 mounted on a lever 16 pivoted at 17 and controlled by a spring 18. When the indicator cylinder is rotated, the rollers 15 ride in and out of the serrations, in said wheel, and said spring holds said rollers in said serrations when any one of the plates is opposite the glass 4, thereby preventing said plates being accidentally rotated.

The plates 10 and the end members 7 are surrounded by a casing 19, one end of which is provided with indications corresponding to the indications on the plates as will be seen in Fig. 3. These outer indications are for the motorman; to enable him to determine when he has set the indicator for the public. By means of these indications, and the crank 13, acting as a pointer, the indication on the plate 10 opposite the glass 4 may be ascertained by the motorman. To permit the indications to be observed at night, electric lamps 20 are placed in the rear of the front or exposed plate 10. The said lamps are attached to the inner side of hubs 21 of the end members 7. The pintles 6 are provided with openings 22 for the lead wires 23 of said lamps. To prevent the side members, and the lamps and plates carried thereby being continuously rotated, and to prevent the wires 23 being broken by twisting the crank 13 is provided with a projection 24 adapted to engage a web 25 on one of the brackets 5.

Having described my invention I claim:

In an indicator for street cars, the combination with a revoluble indicator consisting of a casing having transparent side plates with indications inscribed thereon, of hollow pintles extending from the ends of said casing, brackets forming bearings for said pintles, one of said brackets having a stop thereon, lamps mounted on and fixed to said casing, electrical conductors extending from said lamps through said pintles, and a crank moi nted 011 one of said pintles having a In testimony WhereofI afiix my signature, pro ect1on thereon adapted to engage the in presence of two witnesses. stop on sald bracket to limit the rotation of said revoluble member, whereby the elec- HENRY GEBHART. trical conductors are prevented from being WVitnesses:
