TO ALL WIIOM IT MAY CONOERN:

Be it known' that I, THOMAS G. ESTES, of Fall Riveig'in/the county of Bristol, in the State of Massachuseits, have invented a new and improved Mode of Strikingr a Gong, Bell, orTriangle; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings,

and to thc letters of reference marked thereon.

My invention consists in thev application of .clock-work for striking a gong, Abell, or triangle, as herein described.

Figure 1 is aperspective view of a Vgong and stand to which my invention is applied.

Figure 2 shows the machinery as seen from above, with gong and top plate of frame removed.

Figure 3 is a profile view with gong removed.

Figure 4 shows a portion of the-stop-work ofthe machinery:

Fig. 1. Al is the gong; IB'l the stand; C knob on the top of the main shaft.

Fig. 2. B2 stand; Dl main-spring; F2 dog; G2 arm attached to dog; H2 hammer; a2 a'z a, etc., pins secured in and projecting abovethe upper surface of wheel L2, (the latter is attached to main shat't 132,) which pins strike successively against;4 the arm I2 ot' hammer as the 'wheel revolves, causing the hammer to strike the bell as many times as there are pins on the wheel.

Fig. 3. B3=stand; D3 main-spring; E3 lever;. F3 dog; L3 wheel secured to shaft P3.

Fig. 4. E4L lever, shown by E2 (iig.,2;) Ki'cam on lower end of the main shaft; c? d* pins to prevent the lever from moving too far in either direction'.

Operation..

The different parts of my invention being constructed as shown and described, its operation may be noted.

The cam on the lower end ofthe main shaft liberates the machinery when the main-spring is wound up, and bars it when run down. Turning knob O (g. 1) winds up the main-spring till at the end of one revolution the cam K" (fig. 4) strikes against the outside of projection b* (tig. 4) of lever E, (tig. 4,) and carries back the lever till stopped by pin c" (iig. 4.) As 'the lever moves back the free end strikes against projection x2, (iig. 2,) which throws in the arm Gr2 (g. 2) clear of and frees the tlywheel, permitting the shaft to revolve till it has made one revolution, when the cam K4 (fig. 4) strikes the inner side of projection b* on lever E4, 4,) forcing the lever in till stoppedl by pin cl, (tig. 4.) The free end of lever pressing against point y2 (tig. 2) throws the arm (Jl2 (iig. 2) ont against the y-wbeel, preventing it from revolving till again liberated by winding up t-he main-spring. The number and time of strokes may be varied according to the desire of those using the bell.

I do not cla-im any mode previously invented or patented for striking gongs, bells, and triangles, but what I claim as my invention, and desire to secure by Letters Patent, is

The combination of .gong A1, stand B3, knob Ol, lever E3, d og F3, arm G2, hammer H2, and cam K, with clock-work, as herein set fort-h andy described.

THOMAS G. ESTES.
