STREET-INDICATOR.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed September 13, 1916. Serial No. 119,873.

To all whom it may concern Be it known that we,WILL1AM O. BUN- NELL and QUINCY A. GATES, citizen of the United States, and residents of Wilkes- Barre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Street Indicators, of which the following is a specification.

The present invention relates to card, picture and sign exhibiting and has particular reference to new and useful improvements in changeable exhibitors for streets, stations and the like when used in connection with street cars or railway trains.

The primary object of our invention is to provide a novel and simple street and station indicator for street cars, railway trains and the like which may be operated by the conductor 0r motorman, or may be operated automatically.

Another object of our invention is to provide a changeable exhibitor of the class described having alarm means associated therewith for directing attention of the passengers and others to the indications given by the device.

A further object of our invention is to provide a changeable exhibitor of the class described which is strong and durable, effective in operation and cheap to manufacture and maintain.

Other objects and advantages to be derived from the use of our improved changeable exhibitor will appear from the following detailed description and the claim, taken with the accompanying drawings, in which- Figure 1 is a longitudinal sectional view of a street car showing a pair of our improved indicators installed thereon;

Fig. 2 is an enlarged longitudinal vertical sectional view of an indicator embodying the improvements of our invention; and

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 2 looking in the direction of the arrow.

Referring more particularly to the draw- 4 ing, wherein similar characters of reference designate like and corresponding parts throughout the various views, 1 designates the housing of our improved street indicator the same having a sight opening 2 in one wall thereof.

The exhibiting mechanism of our improved indicator includes a rack bar 3 having a plurality of openings 4 formlng teeth.

A wheel 5 is provided mounted upon a shaft 6 and rotatable therewith, said wheel having a plurality of radially extending pins 7 for engagement with the openings 4. The rack bar is movable in guides 8, the free end of the rack bar being connected to a strap 9 which may extend throughout the length of a railway car or train.

Apinion 9 is mounted on the shaft 6, said pinion being connected with a gear 10, said gear being carried by roller 11 ournaled in the side walls of the housing 1. A web 12 having thereon the names of streets, advertising matter, or any other indications to be exhibited is wound about the roller 11, the web being trained over a roller 13 and then wound upon a roller 14. A crank 15 is provided for engagement with the roller 14 to rewind the same after a run.

To maintain the rack bar 3 in normal position we provide a pair of retractile springs 16 connected to one wall of the housing and to a pin 17 extending downwardly from said rack bar.

An alarm mechanism is provided for directing attention of passengers and the like to the indicator, said mechanism including a pair of bells 18 between which is pivotally mounted a hammer 19. The lower free end of the hammer is adapted to be engaged by oppositely arranged enlargements 20 formed on the rack bar, a pair of retractile coil springs 21 serving'to maintain the hammer in the normal posltion as shown in Fig. 2.

When installing the device a pair of the same is employed, the same being designated. A and B in Fig. 1 and being placed adjacent the end of a railway car C. Supports 22 may be provided throughout the length of the car carrying the strap 9. A roller 23 is disposed beneath the rack bar 3 adjacent a point at which the same engages with the wheel 5 so as to prevent buckling of the rack bar.

A spring pressed pawl 24 is carried by the wheel 5 to engage the pinion 9 when an impulse is given to the rack bar, the pawl permitting return of the rack bar to normal position after a movement of the web. The crank 15 may be employed to rewind the web after each run. Both of the indicators are independently operable from either platform of the car so as to each indicate the station or street.

From the above description taken in connection with the accompanying drawing, it

is thought that a clear and comprehensive understanding of the construction, operation and advantages of our invention may be had, and while We have shown and described the device as embodying a specific structure, We desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope of the invention as claimed.

Having thus fully described our invention, What We claim as new and desire to secure by Letters Patent, is:

In combination with a changeable exhibiter having horizontally alined Ways in its lower portion, movable exhibiting means, an actuating bar passing through the cas- Gopies of this patent may be obtained for five cents each, by addressing the ing and slidable in said Ways connected to the exh bitlng means for operatlng the same, sa1d bar having a lug formed With a pocket on its upper side, bells arranged in the caslng, a hammer pivoted in the casing havlng one end thereof engaged wlth the pocket in sa1d lug and spring means connected to sa1d hammer and said actuating bar for normally maintalnmg the same 1n neutral position whereby to permit actuation of the hammer upon sliding movement of the actuating bar in either direction.

In testimony whereof, We affix our signatures hereto.
