HAItItIE B. HART, OF PHILADELPHIA, PENNSYLVANIA.

BICYCLE-BELL.

SPECIFICATION forming part'of Letters Patent No. 275,485, dated April 1o, 1883.

1o all whom it may ooncern Be it known that I, HARRIE B. HART, of the city and county ot' Philadelphia, in the vState of Pennsylvania, have invented a certain at all times when in position and etfectuallyA prevent accidental displacement.

To these ends my improvement consists in the combination of a bowl having a central shank or hub formed in one piece with its body, a base or bearing fitting against the shank on one side, and having on the other a bearingsurface for the support to which the bell is to be connected, and a locking screw or pin uniting the shank and base and being entirely within the same, so as to be retained in position by the support.

The improvement claimed is hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a rear view of `a bicycle-bell embodying my invention; Fig. 2, a transverse section taken between the clapper and the base piece, and Fig. 3 a centralsection taken at a right angle to Fig. 2.

In the practice of my invention, I cast centrally upon and in one piece with the bowl A a shank or hub, a, the outer end of which is fitted against a base or bearing-piece, B, preferably by entering a socket, b, on one side thereof, or by engaging projections thereon in the manner of a clutch. Upon the opposite side of the base B there is formed a recessed bearing-surface, b', which may be either curved or plane, as desired,for the reception of the support, post, or bracket C, to whichvthe bell is to be connected, such connection being effected by a cap, B', bearing against the opposite side of the support C, and made fast by clamping- Application filed.

screws b2, whichv en gage the base B. The shank al of the bowl and the base B are united'by a locking screw or pin, D, the head of which is Hush with or slightly below the bearing-surface b of the base, so as to be entirely within the same, and to be retained in such position by the support C, which covers it when connected to the' base. rlhe clapper E is formed upon or secured to an arm, I', which swings upon a pin, b3, on the base, below the socket b, and is returned to initial position after each movement by a spring, e.

It will be seen that by the above construction the bowl is held securely to the base, and without the possibility ot' being loosened or displaced until removed from the support. Further, by reason of the rm connection of the parts, the proper action ofthe clapper upon the bowl in ringing is insured at all times, and the screw is protected from risk of breakage by falls.

I claim as my invention and desire to secure by Letters Patent- 1. The combination, substantially as set forth, of a bowl having a shank formed in one piece with its body, a hase fitting against said shank and having upon its opposite side a bearing-surface for the reception of a supporting post or arm, and a locking screw or pin connecting the shank and base and entirely within the same, so as to be retained in position when the bell is connected to a support.

2. The combination, substantially as set forth, of a bowl and shank, a base having on one side a socket to receive the end of said shank, and on the other a recessed bearingsurface for the reception of a support, a locking screw or pin passing through an opening in said bearing-surface and en gagiu g the shank, and a cap and clamping-screws adapted to secure said base to a support which will cover the head ofthe locking-screw.
