SPECIFICATION forming part of Letters Patent No. 493,042, dated March 7, 1893.

Application filed June 20,1892. $erial lid 87,343. (No model.)

To all whom it may concern:

Be it known that we, ALBERT A. PAGE and WILLIAM E. SPARKS, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Bells; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a view of the bell from the rear showing the operating lever. Fig. 2, a top or front View with the belland upper plate 0, removed showing the operative mechanism. Fig. 3, a vertical central section showing parts in side View. Fig. 4, a transverse section cutting on line w:c of Fig. 3 looking down upon the lever.

This invention relates to an improvement in that class of bells adapted for door and similar purposes, and in which a clock work with a main spring is employed as a means for operating the hammer, the mechanism being normally locked so as to prevent its operation upon the hammer, but released by a push or pull applied to the locking device, so that upon such push or pull the mechanism will operate to strike the bell until such push or pull ceases, then the stopping of the operation of the mechanism will be automatic, the object of the invention being a simple looking device, certain in its action, and not liable to disarrangement, and the invention consists in the construction as hereinafter described and particularly recited in the claim.

A, represents the base by which the bell is held or secured in any desired position. Within the base is one plate B, of the clock-work.

C, represents the second plate of the clockwork, which is supported upon the plate B, by the usual pillars. On the plate C, the center-post D, is arranged or formed, and upon the outer end of the post the bell E, is secured, in the usual manner, the bell being preferably of a size corresponding to the base, so that the bell with the base forms an inclosure for the clock-work. The operating mechanism is arranged between the plates B and C, in the usual manner, and consists of a centerwill cause the rotation of the arbor in the opposite direction. On the arbor the main gearwheel H, is arranged, in the usual manner,

with a spring-pawl connection I, which engages a ratchet-wheel J, on thecenter-arbor F, all in the usual manner. The main-wheel H, works directly or indirectly into an arbor K,which carries an escapement-wheel L. The hammer M, is attached to an arbor N, and the shaft N, carries a verge 0, adapted to work into the escapement-wheel L, and so that under the revolution of the escapement-wheel L, a vibratory movement will be imparted to the hammer, in the usual manner, and so that when free, the reaction of the spring will cause the escapement wheel to revolve, and the hammer to vibrate, the hammer being adapted to strike the bell, all in the usual manner.

As a means for locking and releasing the mechanism, a lever P, is hung upon a fulcrum Q, upon the rear or under side of the plate B, and so as to swing in a plane parallel with the axis of the arbors of the clockwork, and a suitable spring R, is arranged, the tendency of which is to force the lever P, outward, or away from the plate B, and yieldingly hold it in such position. Thepallet-arbor N, extends through the plate B, and near its outer end is constructed or provided with a collar S, which is flattened upon its two sides, as seen in Fig. l. The lever P, extends toward the projecting end of the arbor N, and is con- 9 5 structed with a slot T, which in Width corre sponds to the narrower width or diameter of the collar S, and so that under the action of the spring R, the lever P, will normally stand engaged with the collar S, as seen in Figs. 1, I00 3 and 4, and because of the fitting of the narrow or angular collar S, into the corresponding slot T, of the lever P, the hammer-arbor is held against rotation, and thereby the mechanism locked to prevent its operation, but when the lever P, is turned upon its fulcrum, as indicated in broken lines Fig. 3, so as to throw the lever out of engagement with the l ion of the hammer through an esc'apment- 1 wheel and a pallet on the hammer-shaft, nor

arbor N, then themechanism is released, and free for operation under the reaction of the spring. The operation of the lever may be made by means of a pull from a distant point, through a wire U, attached to a tail V ofthe lever P, the pull upon which will impart the disengaging movement to the lever, and so soon as the pull is released, the reaction of the lever spring will throw the lever again into engagement with the collar S, and lock the mechanism, and so hold it stationary or in sus'pense until again released.

The releasing device may be by means of a push spindleW, applied tothe lever, as seenin Fig; 8, and so that a pull will force the lever to its disengaging position. The spring is wound by means of a handle X, applied to the outer end of the center-arbor,

bntthe winding mechanism may be any of the 5 u hold it; in* such connection,- the lever being j adapted to be turned upon its fulcrum out of known devices whereby the required rotary movement may be given to the spring-arbor to prod-ucethe winding.- Thelever while outside the plate B,is brought within the base A,

so that when the base is secured, the' lever will i V specification in the presence of two subscribing witnesses.-

be free for operation, as clearly seen in Fig.3. While it is preferred to attach the collar to or form it upon the hammer arbor, it will be evident that it may be applied to any other arbox of the mechanism between the centerand hammer arbors, and it will be also evident that the shape of the collar is immaterial except that it be angular, and so as to be embraced by a corresponding slot or recess in the lever.

From the foregoing it will be understood that we do not claim broadly a bell provided with a clock mechanism to produce the operado we claim broadly the combination of such mechanism with a locking device whereby the the said mechanism may be held in suspense and released by a push or pull applied to the locking mechanism, but

What we do claim as our invention is The combination of a base carrying a bell, a clock-work composed of a main-spring and mechanism for impartin g vibration to the hammer-arb'or, an arbor of the said mechanism constructed with an angular shaped collar, a lever arranged to swing in a plane parallel 1 with the axis of said arbor, and constructed with a slot corresponding to'said angular col- 1ar,a spring the tendency of which is to throw the said slotted lever into engagement with the said collar of the shaft and y'ieldingl'y engagement with said arbor, substantially as l and for the purpose described.

In testimony whereof we have signed this ALBERT A,- A -a WILLIAM E. SPARKS.
