STREET-INDICATOR.

Specification of Letters Patent.

Application filed January 11, 1909. Serial No. 471,665.

more particularly to such a device adapted.

to indicate the routes and stops of street cars, and has for its object to provide such a device provided with an effective and novel operating means.

A particular object of the device is to provide an actuating mechanism adapted for incorporation in electric cars. In furtherance of this object it is purposed to provide a device adapted for engagement upon trolley poles, to cotiperate with projections carried by wire supports.

Another object is to provide such a device which may be manufactured at extremely low cost and which will occupy but small space when installed upon a car.

Other objects and advantages will be ap parent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims, and that any suitable materials may be used withoutdeparting from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a front view of the device, Fig. 2 is a side view of the device, Fig. 3 is a similar view with one of the retaining plates removed, Fig. 4 is a top view of the device, Fig. 5 is a front view of a trolley head with the tripping mechanism engaged thereon, and about to be engaged by an actuating member carried by wire supports, Fig. 6 is a side view of the matter shown in Fig. 5.

Referring to the drawings, there is shown an indicator including a casing 10 engaged detachably over the indicating mechanism A. This mechanism comprises a base plate 11 to which are secured end plates 12 disposed at right angles to the plate 11. The plates 12 have their inner edge portions turned laterally and perforated and secured to the base plate 11 by means of bolts and nuts 13 as shown. The plates 12 are provided with registering bearings 14 rece1v-. mg a shaft 15 therethrough carrying a drum 16 comprising circular members 17 and 18 secured to the shaft 15, the latter member having a series of peripheral ratchet teeth 19. The disks 17 and 18 are provided with spaced series of registering openings 20 adjacent their peripheries, and engaged detachably in the openings there are flexible shaft members 21 carrying indicator plates 22. The plates 22 comprise rectangular sheets of suitable material and normally tend to hang pendent from the shaft 21. A

retarding yoke 23, comprising a rod having its opposite end portions bent in spaced relation is perforated and secured pivotally to the opposite plates 12 so that the plate 22 will spring thereapart, upon the rotation of the drum, the inturned projection of. said yoke being adapted. to engage the outer edge of the plates 22 and. hold the same by its gravdtal weight, upon the pivot point thereof. The member 23 is provided with a pendent projection 24, centrally thereof, and

by reason of its weight is brought into on gagement with the-outer edges of the plates 22. The projection 2st may be bent inward a trifle to engage the plates 22 more positively so that they will be held upwardly uning clearly the face of one of the plates,

upon which suitable characters or illustrations may be depicted.

The shaft 15 projects outwardly of the plate 12 adjacent the disk 18, and carries revolubly thereon an arm 28 having a boss 29 on its outer side carrying revolubly a ratchet member 25 as shown. The movement of the arm 28 is limited by means of spaced projections 30 carried by the plate 12, as shown. It will be noted that the shaft 15 projects considerably beyond the member 28 and is provided with a transverse passage adjacent its extremity through which there is engaged a cotter pin 26 receiving slidably therein, the end of a helical spring 26, the inner end of which is engaged with the ratchet 25 as shown. A spring pressed dog 2'? carried by the plate 12 en- Patented Nov. 1, 1910.

gages the ratchet to prevent rotation thereof in one direction. The arm 28 carries a similar dog 31, and is engaged by a spring 32 adapted to hold it yieldably at the upper limit of its movement. An operating handle 33 is suspended from the arm 28 to be engaged manually for oscillation of the arm 28 to apply tension to the spring 26 as will be subsequently indicated. There is an escapement lever 3%. having engagingteeth 35 spaced equi-distant from its pivotal point and adapted to engage alternately with the ratchet teeth 19 of the disk 18. The lever 31 is provided with an extension 5 engaged by a spring under tension to hold it normally at the lower limit of its movement. Carried slidably by the plate 12 and connected pivotally to the extension 7) of the lever 21', there is a vertical rod (Z projecting below the casing 10 for manipulation to be subsequently indicated. An operating connection j is connected to the upper end of the rod 1:, a resilient member 7 being interposed to prevent severe strain mcident to its operation, which will be subsequently described.

It will be noted that the casing 10 is pro vided with an outwardly offset portion 36, below which there is an opening 37, the edges of which are disposed to lie flush with the face of one of the members 22 when pendent from the drum 19 as shown in Fig. Any legend or other outline upon the plate 22 may thus be easily observed through the opening 37.

Carried upon the trolley pole 38, there is an actuating member 39, formed of sheet material, stamped to present a central yoke portion 10 having a pendent perforated ear 41, and having its opposite end portions turned downwardly against the spaced arms 42 of the yoke, turned outwardly and then down 'ardly again at 42 in spaced relation with the arms 42, said downwardly extending portions 42' projecting some distance below the yoke 40 for a purpose to be subsequently indicated. The upper extremities of the arms 12 and the downturned portion are perforated, and engaged pivotally either upon the axle of the usual trolley wheel 43, or upon suitable trunnions carried by the trolley harp 11.

Carried by the trolley wire 4e?) at the point at which it is desired to operate the indicator, there are trip yokes t6, comprising spaced arms 47 having inwardly turned portions 18 adapted to engage the outer end portions 49 of the actuating member 39 of the mechanism B, carried by the trolley pole 38. The operating bar 32' for transmitting motion from the actuating mechanism B to the indicator mechanism A is extended through suitable guides 38 upon the trolley pole, as more particularly shown in Fig. 5 of the drawings and is engaged with the ear L1 as shown. It will thus be seen that when the arms 49 are engaged by the member 48, the member j will operate the lever 34 and expose a new plate 22 in position as above described.

It is apparent from the above that an effective and simple indicator 'is provided which may be manufactured at a low cost, and which will involve a minimum of expense for installation.

The device is adapted to be incorporated upon electric cars of the type already in use, and the actuating mechanism 13 may be incorporated upon the usual type of trolley pole.

It will be apparent that by means of handle 35 tension may be produced in spring 26 between the shaft 15 and ratchet 2(3 tending to rotate the drum By pressing upwardly on the base of the rod the escapement member 3 1- may be operated to allow rotation of the drum to a proper point, either for starting or to correct errors in the movement of the air, or to accord with change of route.

The plates 22 may be removed and replaced by flexing them together with the shaft 21, which allows sliding disengagement of the ends of the shaft from the openings 20.
