ATTACHMENT FOR CLOCKS.

SPECIFICATION forming part of Letters Patent No. 405,394, dated June 18, 1889.

Application filed November 9, 1888. Serial No. 290,351. (No model.)

To all whom it may concern:

Be it known that I, EDWARD T. CHASE, a citizen of the United States, and a resident of the city and county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Attachment for Striking or Chiming Clocks, of which the following is a specification.

My invention relates in general to improvements in striking and chiming clocks, and more particularly to improvements in that class of clocks called hall-clocks. In many hall-clocks the sound of the gongs is so faint as to be heard buta very short distance, and hence the usefulness and sale of the clock is greatly impaired.

- The object of my invention is to furnish a device by means of which the sound of the gong or gongs will be increased, and an otherwise practically unsalable clock be made salable and useful.

In the accompanying drawings, forming part of this specification, and in which simi* lar letters of reference indicate similar parts throughout the several views, Figure 1 is an elevation of the inside of the back of a hallclock, showing the gongs and bracket to which they are secured and my device for increasing the sound; Fig. 2, a side elevation of the same; and Fig. 3, a section of bracket a on line 1 2, Fig. 1.

A are the gongs; B, bracket to which gongs are secured; c, the back, and D the bottom of.

the clock. The sides and front of the case are not shown.

a is a bracket attached to bracket B, and b a rod, one end of which is attached to bracket a and the other of which rests either directly upon the bottom D of the clock or upon a support 0, which is placed upon the bottom D. The bracket a, which is preferably constructed of metal, is secured to the bracket B, which carries the gongs. The lower part of this bracket a is furnished with a boss cl, which is bored and threaded. The upper end of the rod 19 is threaded, as shown, and is screwed into boss d, its lower end resting either di rectly upon the bottom of the clock or, preferably, upon a metal support 0, which rests upon the bottom D. The rod 12 is screwed down so as to make a firm contact with the support 0, and this rod may be constructed either of wood or metal, and may be either hollow or solid.

It will be understood that the connection between the bracket B and bottom D may be made simply by a rod, one end of which touches the said bracket and the other the bottom; but the way the connection is shown as made in the drawings is preferable, for it may be adjusted at any time.

It will be further understood that by the bottom D of the clock I mean any diaphragm placed across the case of the clock and secured to the sides and front of the case. In the drawings the bottom D is shown near the lower part of the case; but this bottom may be raised to any height, provided, of course, that it is not so high as to interfere with the action of the pendulum.

The device that I have described and shown greatly increases the sound-of the gongs in all chiming and strikinghall-clocks.

I claim as new and desire to'secure by Letters Patent- 1. In a striking or chiming clock, a rod sup ported thereon, one end of which bears against the bracket carrying the gongs and the other against the bottom of the clock, substantially as and for the purposes set forth.

2. The combination, with the gong-bracket and bottom of a striking or chiming clock, of

a bracket having a threaded boss, a rod one end of which is threaded and screwed into said boss, and a support resting upon the bottom of the clock and against which the lower end of said rod bears, substantially as set forth.

EDWARD T. CHASE.
