SPECIFICATION forming part of Letters Patent No. 578,268, dated March 2, 1897.

Application filed August 3, 1896. Serial No.6OL410. (No model.)

To all whom it may concern.-

Beit known that I, LEVERETT ARTHUR SAN- FORD, of Bristol, in the county of Hartford and State of Connecticut, have invented a new Improvement in Bells; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a View in vertical section of a bell constructed in accordance with my invention; Fig. 2, a plan view thereof with the gong removed; Fig. 3, a reverse plan view thereof with the strap of the clip partially broken away; Fig. 4, a detached plan view of the op--' crating-lever of the device.

My invention relates to an improvement in bicycle-bells, the object being to provide at a comparatively low cost a double-stroke bell composed of few parts, durable, not liable to derangement, and producing a clear ringing alarm.

With these ends in view my invention consists in a bicycle-bell having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention as herein shown I employ a gong A, which may be of any suitable construction and which is furnished with a central inwardly-projecting in ternally-threaded hub A, adapting it to be applied to the threaded upper end of a bent gong-post B, the lower end of which is rigidly secured to the center of the cup-like base C of the bell, the said post being of any approved construction. As thus constructed and arranged the gong is concentric with the cup-like base notwithstanding the use of a bent gong-post. The gong is struck for sounding it by means of a rebounding striker D, which, as shown, is disk-shaped in form and has an enlarged central aperture D, which receives a pivot or stud E, secured to the free inner end of a vibrating or oscillating arm or carrier F, the outer end of which is hung so as to swing upon a fixed stud G, located within the base C aforesaid, near the edge thereof. The striker and the free inner end of the striker-arm swing into the bend of the gongpost, which by being bent permits me to employ a larger striker and a longer striker-arm than I could otherwise do. The striker, it may be noted, hits the gong at'points thereon on opposite sides of the pivot or stud G. The outer end of the said arm has rigidly connected with its under face a small pinion H, the teeth of which are taken into by a few teeth formed upon the inner end of a flat opcrating-lever I, the outer end of which is formed into a finger-piece I, which projects through a transverse opening C, formed in the base C. The said lever is hung upon a lever-stud I mounted in the base just in rear of the gong-post B. The said lever is constructed with a long wedge-shaped clearance-slot 1 through which the gong-post passes and which is wide enough to permit the lever to be swung back and forth on its pivot. A short spiral spring J, attached to the lever by means of a pin J and connected with the base C by means of a pin J is provided for returning the lever to its normal position after it has been swung against its tension by the rider, who applies his fingers to the finger-piece I for the purpose of operating the lever. A friction-spring K, secured to the striker-pivot E and bearing upon the upper face of the striker, prevents the same from shifting and rebounding too easily. A buffer L, formed of a thin piece of leather or rubber, is interposed between the lever I and the gong-post B, as shown in Fig. 2, so that the bell will not rattle, the lever being held against the buffer by means of the spring J. In the normal position of the lever and striker-arm the striker is held out of engagement with the gong, so that the same will not he accidentally sounded. On the return or spring-actuated stroke of the lever the striker is only enabled to hit the gong by the slight compression of the rubber buffer L, which under the force of the return movement of the lever yields just enough to let the striker hit the gong and sound the same. The leather washer M, secured to the upper end of the stud G by means of a nut M, prevents the striker-arm from rattling as it is thrown back and forth; but the use of this washer is optional.

The clip employed with my improved bell may be of any suitable construction. As herein shown, it consists of a heavy angularly-bent sheet-metal frame-piece N, rigidly secured to the bottom of the base by being riveted to the lower end of the gong-post, which is thus secured to the base. The said frame-piece N is formed with a finger N and with two pairs of arms N N N N To the said finger N is attached, by means of a screw 0, a flexible strap P, the outer end of which has a longitudinally-arranged series of perforations 1), adapting the strap to be engaged with a pin Q, mounted in the frame-piece N between the arms N thereof, the said arms N being connected by a transversely-an ranged retaining wire 19, which holds the strap in position to maintain its engagement with the pin. The arms N N receive the end of the strap between them and hold it against lateral displacement. By shifting the end of the strap with reference to the said pin the strap may be let up or taken out, so as to fit handle-bars of any ordinary size; but, as before stated, my invention is not limited to any one form of clip.

I would have it understood that I do not limit myself to the exact constructions herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a bell, the combination with a cuplike base, of a gong arranged concentrically therewith, a bent gong-post having the gong secured to its outer end, and havingits inner end secu red to the center of the cup-like base, a rebounding striker, a carrier therefor having its free or inner end extended inward so as to swing in the bend of thebent gong-post,

a pinion connected with the outer end of the said carrier, an operating-lever having a clearan ce-space through which the post passes, constructed at its inner end with teeth for engagement with the said pinion, whereby the carrier is oscillated, and constructed at its outer end with a finger-piece which extends through the said base, and a spring connected with the lever, substantially as set forth.

2. In a bell, the combination with a cup like base, of a gong arranged concentrically therewith, a bent gong-post passed through the center of the cup-like base, a striker, mechanism for swinging the same through the bend of the bent gong-post, and a clip secured to the lower end of the gong-post which is for that purpose extended through the under face of the base, substantially as set forth.

3. In a bicycle-bell, the combination with a base and a gong, of a striker and means for operating the same, and a clip composed of an angularly-bent sheet-metal frame-piece rigidly secured by means of its central portion to the lower face of the base, having two pairs of arms inclined with respect toeach other, having a finger projecting beyond one pair of arms, a transversely-arranged retainingwire connecting the other pair of arms, and a pin, the said clip also comprising a strap having one end secured to the finger of the frame-piece, and its opposite end formed with a series of perforations and introduced into the frame-piece under the retaining-wire in position to have its free end engaged with the said pin which enters one of the said perforations.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
