e'oNo FOR STREET-CARS.

SPECFICATION forming part of Letters Patent No. 27 l,176, dated January 23, 1883,

Application filed October 27, 188:2. (No model.)

To all whom it may concern Beit known that I, CHARLES H. WHITE, a citizen of the United States, residing in the city, county, and State ot' New York. haveinvented new and ruseful Improvementsin Gongs for Street-Gars, &c., ot' which the following is a specification.

My invention relates to improvements in gon gs, particularly applicable for use on streetcars and for analogous purposes.

According to my invention, l t'ornn the hammer shank or shaft in two sections pivoted or hinged together, each section being ot' short length, thereby avoiding the liability to bend, which is so common with the long hammershanks formed in one piece of the gongs in common use. One-half of the shank or shaft is pivoted to the gong-frame, and provided with the necessary extension or arm for the application of the operating cord or strap. This halt' is also provided with a stop -or projection adapted to come against the main crossfpiece of the frame, on which the gong-post is supported, thereby stopping the upwardv motion of the first halt' of the shank or shaft, While -the second or hammer half ot' the shank or shaft, which is pivoted to the first half by means ot' a stop-hinge connection. continues to move by its momentum and strikes the gong. The trame or support is provided with an integral and rigid transverse rest adapted to support the shank or shaft when not in use, and alsoV to take the greater portion ofthe strain offthe pivot on which the shank turns.

The object of my invention is to simplify the construction of the parts, While at the same time they are rendered more durable and ett'ective.

The accompany ing drawings form part of this specification, and illustrate what l consider the best means of carrying out my invention.

Referring to the drawings, Figure lis a side viewofa gongandframewith myimprcvemehts applied thereto, partly in section, the working part-s being shown in a position of rest. Fig. 2 is a similar view with the parts represented in the position of action. Fig. 3 is an under side view of the device complete.

In each of the views similar letters of reterence are employed to indicate correspond ing parts Wherever they occur.

A represents the gong, and B the gong frame or support, which is provided with side hars or arms, b b, for the support of the operating' parts, and is otherwise of ordinary cpustruction, except that it is provided with the integral rigid cross-bar B2, which will be hercinafter more fully described.

U2 C3 is the hammer-shank, and C thehammer-head. The hammer-shank is formed in two parts, C2 G3, the part C2 being pivoted on a piiror stud, c, supported in the bars b b of the frame B, and formed with the necessary extension or arm, c', for the attachment ot' the operating cord or strap D, as will be well understood. The half C2 is also provided with a stop or projection, c2, adapted to come against the cross-piece B ofthe frame B, upon which the post ofthe gong A is supported when the hammershank and hammer are impelled upward by the action of the conductor or other person pulling suddenly on the rope or strap D, as hereinafter more fully explained. The second or hammer half,O3, ofthe shank is pivoted to the first half, G2, by means of a hinge, c, provided with a stop, c, at thc joint, as shown at Figs. l. and 2. The frame or support B is provided with a transverse rest, B2, adapted to support the shank C2 and hammer C when not in use, and also to reduce the strain on the pivot c caused by the constant use of the gong and also by the vibrations ot' the shank and hammer occasioned by the motion of the car.

The operation ot'the device is as follows: The

- parts being in the position shown by Fig. 1,thc

cord or strap D is pulled upon sharply in the usual manner, thereby causing the hammershattand hammer-head C to be thrown upward, asindicatedbyFig.2. Thestopczcomesagainst the cross-piece B', thereby stoppingthe further motion of the half Gzot the shank. The other halt', C3, will, however, by its own momentum and that ofthe hammer-head, be carried upward tothe position shown by dotted lines in Fig. 2, so as to strike the gong. Having struck the gong1 it will immediately fall back to the position shown by full lines in Fig. 2, clear of the gong A, thereby avoiding all clinging or sticking of thehammer to the gong andthe consequent danger of cracking the same by reason of the hammer stopping the vibration of the gong. Immediately the pressure on the ICC cord or strap is removed the shank and hammer will fall into the position shown by Fig. 1, with the section CZ of the shank resting on the transverse rest B2, the force of the returnstroke of the shank G2 being mostly received by the transverse rest B2, thereby greatly saving the Wear and tear on the pin c.

By my peculiar construction and arrangement of the parts the great inconvenience ot' the bending of the ham mer-shafts ot' gongs of this description is entirely prevented, and, in addition, the danger of fracturing the gong is avoided by reason of the hammer at no time being held rigidly against the gong, While, on

the other hand, it falls away from the gong-im- Having thus described my invention, what I claim, and desire to secure by Letters Patent, ls-

i l'. In a gong for street-cars or other similar purposes, a pivoted hammer-shaft formed in two sections or parts hinged together, one section or part being provided with a projecting stop adapted to come against a fixed portion of the frame to stop its motion, the second section or part being free to continue its motion to strike the gong, substantially as shown and described.

2. In a gong for street-oars and other similar purposes, the combination, with the gong A and framing B, provided with Vthe rigid cross-bars B B2, of the pivoted divided and hinged shank (l2 G3, hammer G', and stop c2, substantially as and for the purpose described.
