No. 716,47l. Patented Dec. 23, [902.


(Application filed Oct. 17, 1902.)

(No Model.)






SPECIFICATION forming part of Letters Patent No. 716,471, dated December 23, 1902.

Application filed October 17, 1902.

To all whom, it may concern.-

Be it known that we, GEORGE E. PIOKOP and WILBURR. CORBIN,citizens of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Bells, of which the following is a full, clear, and exact description.

This invention relates to improvements in bells, and is particularly useful for doorbells.

The object of the invention is to provide certain improvements which result in great economies and reduce the construction to few I5 and simple parts. The parts maybe readily assembled.

The preferred forms of the invention are shown in the accompanying drawings, in which- Figure 1 is a front elevation of a structure embodying this invention as it appears in place, the bell properbeing removed and indicated only by dotted lines. Fig. 2 is a section on the line 2 2 of Fig. 1 with the bell in place. Fig. 3 is a front elevation of a detail of construction. Fig. at is a similar-view, partly in section, of a modification. Fig. 5 is a view of a detail. Fig. 6 is a fragmentary view of a portion of the detail shown in Fig. 4.

In the drawings, A represents a portion of a door constituting one form of convenient support for the bell.

B is a frame which may be fastened to the door A in any suitable way-for example, by 5 screws 0 C.

B is an arched portion of the frame B, upon the crown of which may be supported a bell D, the same being secured to the frame by a suitable screw E.

F is a toothed wheel or ratchet centrally mounted upon the operating-rod G, projecting from the handle G, by which the parts may be rotated. The rod G is preferably square in cross-section. Projecting from the arch portion B of the frame Bis a sleeve 13*,

which acts as a sheath for the end of the rod G. This sleeve also, with the collar B on the frame, positions the ratchet F.

H is a striker-frame which, as shown in the drawings, is pivotally mounted in the Serial No. 127,706. (No model.)

frame, so as to rock to and fro by action of the ratchet F, one of the teeth of which alternately engages the arms H H It will be observed that in the frame B there is a space or slot at the upper end to receive the strikerframe H.

L is a collar adapted to pass through the opening in the striker-frame and act as a bearing therefor. The collar L is held in place by means of the screw C, which passes through the sections of the frame B, causing the arched section to bear down against the collar and inturn the collar against the base. The length of the collar is slightly more than the thickness of the striker-frame. Hence when the screw C is set down hard it will not draw the sections of the frame together to an extent sufficient to bind on the striker-frame, but will allow it free motion.

The striker-frame H carries at its free ends strikers I, each of which in the form shown in Fig. 5 has an extended neck I and a head 1 H is a recess in the end of each arm H H adapted to receive the neck I of the striker I. The entrance to the recess is reduced after the striker is inserted to retain it in place, and yet leave it sufficiently loose so that it may act independently to insure a better action.

In Fig. 4, J is a modification of the strikerframe, the extended arms of said strikerframe being flexible. This frame is provided with shoulders J J flwhich correspond in func-, tion to the shoulders H H of the strikerframe H. K K are strikers carried at the ends of the arms of the striker-frame J. These strikers may be rigidly connected to the arms, since the flexibility will allow the strikers to rebound properly after hitting the bell.

As shown in the drawings, Figs. 4 and 6, c the striker-frame may be made of a piece of spring metal, which may be twisted at its middle portion to provide a fiat body for the perforation to receive the pivot which supports said frame.

The front plate M may be secured to the other side of the door A. The handle G extends through this plate M and has a sleeve G to provide a holding means for the rod G.

A washer N may be provided to provide a too bearing and the pin N to hold the handle in place.

The mechanism may be assembled by first securing the frame B to the door or other desired support, then while holding the ratchet F in place inserting the rod G and securing the plate M on the other side of the support, having previously mounted the handle G and rod G through the opening in the plate. The bell itself may be then attached.

All the parts are of simple and durable construction, which may be readily assembled, taken apart, or replaced when desired.

What we claim is- 1. In a device of the character described, a toothed Wheel, means for manually operating the same directly, a pivoted vibrating twoarmed striker-frame coo peratin g directly With said toothed wheel, and strikers carried by both arms of said frame.

2. In a device of the character described, a toothed wheel, means for manually operating the same directly, a hinged flexible two-armed striker-frame cooperating directly with said wheel, and a striker carried by each arm.

3. In a device of the character described, a rotatable toothed wheel, means for manually operating the same directly, a hinged strikerframe having a plurality of arms, a shoulder on each of said arms projecting into the path of the teeth on the Wheel and cooperating directly therewith, and a striker carried at the end of each arm.

4.. In a device of the character described, a toothed wheel rotatably mounted, means for rotating said wheel, a hinged striker-frame located eccentrically of said wheel said frame being extended into two arms, a striker yieldingly carried by each of said arms, points on said arms projecting into the path of rotation of the teeth on said wheel and cooperating directly therewith.

Signed at New Britain, Connecticut, this l5th day of October, 1902.
