STREET AND STATION ANNUNCIATOR.

Specification of Letters Patent.

Patented Nov. 1'7, 15141.

Application filed August 10, 1914. Serial No. 856,052.

To all whom it may concern:

Be it known that 1, CHARLES P. BRADLEY, a citizen of the United States, residing at Pemberton, in the county of Burlington and State of New Jersey, have invented a new and useful Street and Station Annunciator, oi which the following is a specification.

The device forming the subject matter of this application is adapted to be employed upon street railways cars and other vehicles, for the purpose of disclosing to the passengers, the name of the street or station which the vehicie is approaching.

One obiect of the present invention is to provide novel means for operatively connecting the drums. which carry the inscribed web,with the actuating member.

Another object of the invention 1s to pro vide novel stop mechanism for limiting the movement oi the flexible element or web which is assembled with the drums.

Another object of the invention is to provide novel means whereby the direction of movement of the web may be reversed, as is necessary when the caror vehicle runs back over a route previously traversed.

It is within the scope of the invention to improve generally and to enhance the utility of devices of thattype to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in thedetails of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings :--Figure 1 shows the invention in section ;v Fig. 2 is a section taken at right angles to the showing of Fig. 1, parts being broken away; Fig. 3 1s a cross section on the line 33 of Fig. 1; Fig. d is a fragmental sectional detail illustrating the operative connection between the gear train and one drum; Fig. 5 is a fragmental elevation showing a modified form of the invention. v 1n carryin out the invention there is provided a boX-like casing l constituting i -support for the various movable elements of the device, the casing 1 being equipped at one side with a transparent plate Mounted in the casing 1 and extended transversely 1 and is mounted to rotate therein.

thereof are shafts 3 upon which are mounted drums at to which are secured ratchet wheels 5 adapted to be actuated by pawls 6 pivoted to pinions 7 journaled on the shafts 3, the pinions 7 meshing into gear Wheels 8 carried by stub-shafts 9 supported 0d the casing 1.

Located between the gear wheels 8 is an actuating member 10 in the form of a rod.

The actuating member 10 is mounted to right line sliding movement in the casing The actuating member 10 is provided with a rack 11. When the actuating member 10 is rotated on its axis, the rack 11 may be made to mesh into either of the gear wheels 8 and when the actuating member 10 is moved in the direction of its length, that gear wheel '8 with which the rack 11 meshes, and the corresponding drum 4;, will be rotated, the gear wheel 8 meshing into the pinion 7 and the pinion 7 driving the drum l through the instrumentality of the pawl 6 and the ratchet wheel 5. A ring or the like indicated at 12, is secured to one end of the actuating member 10. This ring 12 may be con nectedwith a cord or the like (not shown) so that, the structure may be operated from a distant point. The ring 12 coacts with the casing l, as will be evident from Fig. 1, to limit the movement of the actuating member 10 under the action of a retractile spring 25, one end of which is secured as shown at 26 to the casing 1, and the other end of which is secured to a washer 27 in which the actuating member 10 is journaled, there being'a collar 28 on the actuating member 10 against which the washer 27 bears. At one end, the actuating member 10 is provided with a handle 14 whereby the actuating member 10 maybe rotated on its axis, to cause the rack 11 to mesh with either of the gear wheels 8.

A means is provided whereby the actuat ing member 10 will be prevented from rotating, saving when forcibly turned through the medium of the handle 14. With this end in view, a support in the form of a block or the like is attached to the casing 1 and carries a stiii spring tongue 16. As indicated at 38, opposed sides of the actuating member 10 are flattened to coact with the free portion of the tongue 16. The function of the spring tongue 16 is toprevent the rack ble structure, the cams, respectively, en-

gaging the stop to move the stop out of contact with the flexible structure when the rack is moved in one direction.

3. In a device of the class described, a pair of drums; a flexible structure terminally secured to the drums; an actuating train operatively connected with each drum and including a gear wheel; a rack provided With opposed cams and having opposed, flattened side faces, the rack being mounted to slide in the direction of its length and to rotate, the rack meshing into one gear wheel, the rack being movable in the direction of its length to actuate the said gear wheel and the corresponding drum and being rotatable to cause the rack to mesh into either gear wheel; a spring adapted to coact at different times with the flattened side faces of the rack to hold the rack in mesh with the respective gear Wheels; a pivotally mounted stop adapted to coact with the flexible structure, the cams engaging the stop at different times to move the stop out of contact with the flexible structure when the rack is moved in one direction.

4. In a device of the class described, a rotatablymounted drum; an actuating train operatirely connected with the drum and including a gear Wheel; a rack bar mounted to slide in the direction of its length and meshing into the gear wheel, the rack being provided'with a flattened side face and having a cam; a spring bearing against the flattened side face of the rack to hold the same in mesh. with the gear Wheel; a flexible structure secured to the drum; a pivot ally mounted stop adapted to coact with the flexible structure, the cam being adapted toengage to move the stop out of contact with the flexible structure when the rack is moved in one direction.

In testimony that I claim the foregoing as my OWIIHI have hereto affixed my signature in the presence of two witnesses.

CHARLES P. BRADLEY. \Vitnesses:
