IMPRovEMENT IN CALL-BELLS.

Specification formirgpart of Letters Patent No. 147,4S6,'dated February 17, 1874; reissue'No. 5,822, dated April 7, 1374; application filed March 24,1874.

To all whom it may concern Be it known that I, HENRY A. DIERKEs, of the city, county, and State of New York, have invented certain new and useful Improvements in Bells, of which the following is a specification The object of lny invention is to produce a bell, more especially adapted for use as a table or call bell, of simple and convenient operation, and attractive appearance 5 and it consists in the combination, with one or more bells, of ahand-wheel, so applied and arranged in connection therewith as to operate the hammers and ring the bell or bells when the said wheel is rotated, or partly rotated, upon its axis; and in the arrangement of a wheel between two bells placed mouth to mouth; and in other novel features, hereinafter described.

Figure 1 of the accompanying drawings is an elevation of my improved bell, viewed on a line with the periphery of the hand-wheel. Fig. 2 is a longitudinal section of the same; and Fig. 3 is a transverse view on lines a' w of Figs. 1 and 2, one of the bells being removed, and the axial rod and one of the supporting-arms being in section.

As shown in the drawings, A A are two hemispherical or gong-shaped bells, mounted on, and secured immovably to, the cranked axial rod B, passing centrally throughthem, and which is also secured immovably to the curved and llexible supporting-arms C C, which rise from the base or standard D. Upon the center of the axial rod B is mounted the handwheel E, which is arranged to revolve thereon within the bells, preferably between the mouths ofthe same, the handles a ce ofthe wheelpassing between the mouths, and proj ectin g beyond the exterior of the bells, as shown. rlhe bells are arranged, preferably, so close together that space enough is left for the handles only of the Wheel to pass through and allow the same to freely rotate. The periphery of the wheel lies within the bells, as shown, and close to the `interior sides of the same, so that the small space between the mouths of the two bellsis thus closed, and the interior mechanism concealed from view. The axial rod B is cranked, as shown in Fig. 2, and 1n the cranked portions are pivoted small rock-shafts or pins k 7c, from which depend the hammers f f and cranks or cams e e. The cams c e project toward the hub of the wheel, and are alternately struck by projecting pins g g on the hub of the wheel when the same is rotated, an d are oscillated thereby, causing the hammers to strike and ring the bells. This will be understood on reference to Fig. 2 and to Fig. 3,where the hammer is shown upon the point of striking.

Instead of the rockshafts kk, springwire may be used for the hammer-rods, and the same actuated by the direct contact of the pins g g and a straight axial rod may be used in lieu of a crankedone.

A portion p on the lower side of each bell is cut away, as shown at l Z, Figs. 1, 2, and 3, forming an open space, in which the hammers swing and ring the bell by striking against the edges of the projecting portion; but, if preferred, the hammers may be arranged to swing inside the bells, and the slot or opening be dispensed with. In the former case, the base may be extended upward in an ornamental oral or other design, sopas to cover and conceal this open space, as represented by the dotted lines in Fig. 1.

By the use of the recesses Z Z the hammers are made to strike the bell upon its edge, and thereby produce a clearer sound. allow the hammers a larger swing, so that the stroke will be more eifective; and, by striking upon the edges of the bells the same are not so liable to be fractured or injured by wear as if struck upon the inner surface.

To ring the bell it is only necessary to move one of the handles a. a with the linger when the wheel willthen revolve, and its momentum will vibrate the hammers and keep the bell ringing for several seconds.

-In this way vI produce a bell of extremely unique character and ornamental appearance, and of very vsimple and facile operation.

I do not wish to confine myself to the par ticular mechanism herein shown by which the hand-wheel is made to operate thehammers, as other methods of accomplishing this result may be readily devised; and the wheel and hammers may be connected with each other in They alsoa positive mann-er by' eccentrics, cam-s, cranks, orl other devices. Nor do I wish to confinemyself to the particular form of bell shown; butv 1. In combination with two bells, arranged mouth to mouth, a wheel arranged to rotate in a plane parallel with the mouth of the bells, to

2. In combination with one or more bells,a wheel, or its equivalent, operating by its rotation directly ou the striking mechanism, substantially as and for the purpose set forth.

3. In combination with the bell or bells and their striking mechanism arranged within them, a wheel, or its equivalent, arranged within, or partially within, thev bell orv bells, to' op'-v erate the striking mechanism when rotated, asI y set forth.
