MANUFACTURE OF COW-BELLS.

Specification of Letters Patent No. 31,521, dated February 26, 1861.

To all whom it may concern:

Be it known that I, GEORGE C. ALBAUGH, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Improvement in the Manufacture of Cow-Bells; and I do hereby declare that the following is a full, clear, and exact descript-ion thereof, reference being had to the accompanying drawings, making a part of this specification, in which-.

Figure 1 is a perspective View showing the under side of the improved bell. Fig. 2 is a cross section through Fig. 1, showing the manner of uniting the plate. Fig. 3 is a section showing the old method of uniting the plates in the manufacture of cow bells.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to make my improved bell I will proceed to describe its construction.

The invention is fully illustrated in the drawings, in which a is one side of the bell and b the other. The bells are formed of one sheet of metal, suitably cut to give the desired shape when the edges are put together. Thisform is represented in Fig. 1, which shows a complete bell of the improved make. The edges 0, c, of this bell are stamped, hammered, or otherwise bent as shown in Fig. 2, so as to form a rabbet, into which laps the edges 0, 0, of the side, a, forming on one sideinside or outsideof the lapped edges, a flush joint which is riveted at r, Fig. 1, before the bell is brazed. hen this bell is now brazed, in the usual manner, the melted metal will be retained between the lapped portions of the plate and form a perfectly brazed joint, while in the simply lapped joint shown in Fig. 3, the metal will flow through the joint without uniting the plates perfectly; the joints in the old way of making bells of this class being frequently imperfect, give in consequence of this imperfection a low dull sound. The sound, in order to be heard any distance, must be clear and distinct with but very little of the ring sought for in cast bells of every sort, and none at all of that hollow or rattling usually heard in the bells made, represented by Fig. 3. Any considerable imperfection in the joints destroys the sound almost wholly. The usefulness of the sound therefore is always proportioned to the degree of approach the bell makes to perfection.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is The method herein shown and described of retaining the melted metal between the lapped portions of the plates during the brazing operation, all as set forth.

GEORGE C. ALBAUGH.
