TABLE-BELL.

SPECIFICATION forming part of Letters Patent No. 495,650, dated April 18, 1893. Application filed May 23, 1891. Serial No. 398,823. (No model.)

To aZZ whom it may concern:

Be it known that we, CHARLES ALLEN and SAMUEL GOULDEN, citizens of Canada, residing at Newark, in the county of Essex and State of NewJersey,have invented certainnew and useful Improvements in Table-Bells; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The objects of this invention are, to provide a table bell that may be given a succession of strokes by one slight impulse of the hand, to reduce the cost of construction; and to secure other advantages and results some of which will be set forth hereinafter.

The invention consists in the improved table bell and in the arrangements and combinations of parts substantially as will be hereinafter set forth and finally embodied in the claim.

The figures of the accompanying drawings are deemed suificient to illustrate the invention, Figure 1 being a plan and Fig. 2, a side elevationof atable bell of the improved construction.

In said drawings, a indicates a bed plate having a broad base to engage the table and provide a substantial and firm support for the turning or revoluble mechanisms and having a seat, I), for an annular frame, 0, which carries a gong or bell, d, in any suitable manner. The said annular frame, 0, stands out about flush with the edges of the bell, and forms a box or inclosure for the train of gearing by which speed is imparted to the bell hammer and, on its peripheral face, provides rigid or substantial bearings for the series of projecting finger pieces, knobs, or studs hereinafter referred to. Said revoluble frame has an annular portion of about the same diameter as the outer rim of the bell, it being shown slightly larger in the drawings. Upon the periphery of said annular portion, are means to receive the fingers, the said means being preferably a series of finger projections, h, against which the finger can easily and conveniently press so as to occasion a turning of the frame.

Within said frame are secured an inner frame or carrier for a train of gear wheels, connecting, at one end of said train, with a carriage, e, for a loose bell hammer or bell hammers,f, arranged at the extremities of said carriage. The said carriageis pivoted on the arbor, c, having a small cog-Wheel or pinion, e which meshes with a larger cog wheel, e centered, as at c on a shaft with another small pinion, c and this last said wheel engages another large wheel e, which engages acenter pinion or cogged arbor f having at its lower extremity an angular socket to receive an angular stud, g, projecting upward from the seat I).

The train of gearing has bearings for its several pinions, wheels and arbors on the inner frame or carrier before referred to, the wheels and pinions being arranged between upper and lower plates 1', i, of said inner frame.

In operating the device to produce a succession of strokes on the bell the table or frame, a, is turned pivotally a short distance on the bed plate or stand a. The angular post or stud g, projecting up from the said bed-plate, holds the pinions, while the other portions of the train of gearing are caused. to turn with frame, 0, and bell, d, fixed thereon. Thus rotary movement is imparted to the wheel, 6 and to the other wheels of the train,

' the motion increasing in rapidity toward the wheel or pinion 6 so that the hammer carriage fixed to the arbor, e, is given a speed that will insure a quick succession of strokes on the bell.

By the construction described, the pressure or force exerted by the hand to sound an alarm is applied at a distance from the pivots upon which the bell carrying frame revolves and thus, by either a pushing or pulling opera tion of the hand, or of a single finger thereof, the train of wheels is worked with the greatest ease and with but a slight movement of the projecting finger pieces. In this, the present device differs in operation and result fromthat class of devices having a finger knob projecting above the center of a fixed bell and adapted In a table bell the combination with a bed train of gearing and adapted to be struck by plate adapted to be placed upon the table or the hammer when the annular frame is roother support, a stationary or rigid post and tated, substantially as set forth.
