N-PETERS, PNOTO-LIVTNOGRAPHER, WASHINGTON 0 C .dlniini san Letters Patent No. 90,811, dated June 1, 1869.

IMPRovEn BELL.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, ABNER G. BEVIN, of East Hampton, in the county of Middlesex, and State of Connecticut, have invented a new and useful Improvement in Gong-Bells, and I declare the following to be a full and .exact description thereof, reference being had to the accompanying drawings, and t0 the letters of reference marked thereon, making a part of this specification.

My improvement is intended for the purpose of giving a trip, or sudden motion to the tongue of a gongbell at each end of its vibration, or play.

Figure 1 is a'plan view of my device, with the bell removed.

Figure 2 is a side elevation.

The same letters indicate the same parts.

A is the bell, upon which the head of the tongue B strikes.

The tongue is pivoted, at s, to the right-angled swinging piece a, which, in its turn, is pivoted to the bottom platefl at i.

The pull-wire b is. attached to the other end of this swinging piece.

dis a spiral spring, attached firmly, at one end, to the standard D.

It is coiled around the standard, and attached, at its other end, to the swinging piece a. Its purpose is to bring the tongue a back to the position shown by the black lines in fig. 1, after it has been pulled over to the position shown by the red lines in the same figure.

The tongue B, after pivoting, at s, to the end of the swinging piece a, continues in a straight line through a hole in the stud, or bridge a. It fits loosely in this hole, and, as the tongue assumes its different posi tions, this straight piece plays loosely in the hole in the stud.

All the parts heretofore named are old, and I believe their operation is generally understood.

My invention inthis gong-bell is the placing of the spiral spring x, or its equivalent, upon the straight part of the tongue, between its pivot s and the stud c, resting at one end against said pivot s, and, at the other, against the stud c; and its office is to give the tongue of the bell a trip, or sudden motion at each end of its vibration, or play.

When the tongue is pulled over toward the position shown by the red lines in fig. 1, this spring will tend to throw the tongue sharply against the bell upon that side, and, when the tongue springs back to its first position, it will help the force of the stroke upon that side.

I claim, as my invention- The spiral spring a, or its equivalent, placed upon tlle'tongue B, between its pivot s and the perforated stud c, for the purpose of giving a sudden trip to the tongue at both ends of its vibration, or play; all arranged, constructed, and operated as described.

Dated April 13, 1869.
