SPECIFICATION forming part of Letters Patent No. 588,820, dated August 24, 1897. Application filed March 1, 1897. Serial No. 625,477. (No model.)

T all whom it may concern/:

Be it known that I, WILLIAM E. GARD, of Brooklyn, in the county of Kings and State of New York, have invented a new Improvement in Portable Bells; and I do hereby declare the following, when taken in connection with the accompanying; drawings and the letters of reference markedthereon, to be a full, clear, and exact description of the same, and which said drawingsconstitute part of this-specication, and represent, in-

Figure 1, a sectional View of `a bell vconstructed in accordance with my invention;v

Fig. 2, a view thereof with the gong removed; Fig. 3, a detached perspective View of one form which the double-ended longitudinallymovable striker may assume; Fig. 4, a yiew of the striker in central longitudinal section.

My invention relates to an improvement in portable bells, designed, primarily, to be used as bicycle-bells, but capable of use in a great variety of other situations, the object being to produce an extremely simple and compact bell composed of few and durable parts and constructed with particular reference to sounding a quick, clear, and penetrating alarm.

With these ends in view my invention consists in a bell having a longitudinally-bowed double-ended striker having positive longitudinal movement and gravity locking or tilting movement and coacting with a striking-lug formed upon the inner face ofthe gong, with which its rotation is substantially concentric.

My invention further 'consists in -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 longitudinally-bowed double-ended plate-like striker A, furnished at its ends with independently-formed but fixed hammers A' A2, having short integral rivets ct a, by means of which they are secured to the ends of the plate, which is formed with a central longitudinally-arranged slot A3,having straight side Walls. striker to be set Vdown over an oblong coupling-lug B slightly narrower than the said slot- AS, considerably shorter than the same,

This slot adapts thel finger-lever H', which is hung upon a stud H2 and formed with. an outwardly-projecting finger-piece H3. A spring I, connected with the finger-lever and `with the bell-base F, provides for actuating the finger-lever in one direction.. vBy reference to. Fig. 2 it will be seen that the linger-lever is formed with a wide segmental 'clearance-slot, which permits it to clear the hub B2 of the pinion B. A fibrous washer J and two metal washers J J' are interposed between the upper face of the double-ended striker and the inner end of the hub D of the gong, the said hub and washers holding the striker in position without interfering with its freedom of movement.

It will be clear from the foregoing description when taken in connection with the drawings that when the finger-lever is operated and the train actuated the double-ended striker Will be rapidly revolved and thrown outward by centrifugal force until one of its hammers strikes the inwardly projecting striking-lug'D2 of the gong, when the striker will be positively pushed longitudinally in the opposite direction, after which it will immediately rock or tilt under the. action of gravity, and the hammer A', which has just hit the striking-lug D2, being lifted virtually above the same, as shown in Fig. 2, and the hammer A2 at the opposite end of the striker being depressed, so that its outer edge comes over near the inner periphery ofthe gong D, as shown in the same figure. The rocking of the striker in the manner stated causes the hammer which has just hit the striking-lug to be lifted and cleared from the same, and the other ,hammer to be brought into position tostrike vthe lug a sharp square blowas soon as the striker has made another half revolution, when the striker will be again pushed longitu- IOO dinally and again locked,with the effect of lifting the hammer A2 and depressing' the hamm er A. It will thus be seen that every time one of the hammers is brought into engagement with the striking-lug that the striker will be moved not only longitudinally, but also rocked or tilted, and that these movements of the striker not only facilitate the clearance ofthe hammers from the striking-lug after the bell has been sounded, but also bring the hammers intothe positions in' which they strike the lug to the best advantage for securing a clear and penetrating alarm. I may point out also that the formation of a coupling-lug integral with thcpinion B' provides a simple and effective mode of coupling the striker with the actuating-train.

I wouldhave it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes andV alterations as fairly fall within the spirit and scope of my invention. Thus instead of applying independently-formed hammers to the ends of the striker-plate the hammers may be made integral therewith, in which case they would virtually constitute weighted or heavier ends I for the striker.

I-Iaving fully described my invention, what I claim as new, and desire to secure by Letters double-ended striker arranged to rotate concentrically with the gong of the bell and adapted to impinge upon a striking-lug formed upon the inner face thereof, the said striker being constructed to have longitudinal movement in opposite directions imparted to it by the impact of its ends upon the said lug, and on account of its said bowed form having rocking or tilting movement imparted to it by the action of gravity.

2. A bell having a longitudinally-bowed, double-ended striker consisting of aplate, and two hammers formed independently thereof and applied to the upper faces of its ends, the said striker being arranged to rotate con centrically with the gong of the bell for the im pin gem ent of its hammers upon a strikinglug formed upon the inner face thereof, and being constructed to have positive longitudinal movement in opposite directions imparted to it by the said impact of its hammers with the striking-lug, and on account of its bowed form having rocking or tilting movement given to it by the action of gravity.

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

WM. E. GARD.
