CALL- BELL.

ill SPECIFICATION forming part of Letters Patent No. 265,045, dated September 26, 1882.

Application filed July 31,1se2. (No model.)

arm projecting from thetongue, and by whichthe latter is vibrated.

In the drawings, Figure 1 is an elevation. Fig. 2 is a central vertical section. Fig. 3 is a perspective view of the base and gong inverted, and of the hollow handle with its plunger, both being detached from the bell and from each other.

The letter A indicates the base, which is an annulus of the common form. From opposite sides of its upper edge rise arms B B, which approach each other, and are united to a screwlhreaded ring, 0, which lies against the under face of the gong D at its central point, and

around an opening formed therein, through which the screw-threaded end a of the handle E passes.

Upon one side of each of the arms B B is formed a flange, I), having a perforation, d, to

receive the pivot upon which the tongue F vibrates. The latter is provided with a headfe, which fits between said flanges, and through which the pivot passes.

The letter F indicates the tongue, having the clapper fand head 6. Upon one side of the latter is formed an arm, Gr, which curves upward and outward from the head 6 and passes between the arms B B. This arm is adapted to pass through a perforation, g, in the tang of the plunger H, said perforation being of such size that the arm will play freely therein.

E is the handle, havinga central longitudinal perforation, in which the plunger H moves. It is provided with a screw-threaded end, a, which enters the ring 0 within the gong.

The parts are assembled as shown in Fig. 2. The gong'D being placed over the arms B B and upon the ring 0, the end of the handle is passed through an openin g therein andscrewed into the ring 0. The -plunger His then inserted, and the tongue is placed between the flanges b b, the arm G being passed into the perforation gin its tang. The pivot upon which the tongue vibrates is then inserted], and the bell is in condition for use.

By this construction I form a free pivotal connection for the tongue, and one which cannot be detached unless the several parts of the device are properly separated.

Theconstruction is cheap, simple, and strong, and by the perforation of the plunger the arm on the tongue 'will retain it in place and prevent it from slipping out of the handle.

7 What 1 claim isy 1. In a call-bell, the combination, with the annular base, of arms extending therefrom upward to support the gong, and having lateral flanges formed thereon, to which the clapper is suspended, and a vertically-moving plunger having a perforation in its tang, through which passes an arm on the end of the bell-tongue, substantially as described. 7

2. p The combination, with the vertically-moving plunger provided with a tang having a transverse perforation, of the bell-tongue provided with a curved arm, which projects into the perforation andis free at its outer, end, said arm being unattached to the tang, but adapted to freely slide in opposite directions through the said perforation when the plunger is operated, substantially as shown and described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. I
