CA LL=-BELL..
SPECIFICATION forming art of Letters Patent No. 385,166, dated June 26, 1888.
Application filed April .23, 1888, Serial No. 271,511.
Kensington, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement pertaining to Call-Bells, of which the following is a description, reference being had to the accompanying drawings, whcrein- Figure 1 is a view in'central vertical section ofa call-bell embodying my saidimprovement. Fig. 2 is a bottom view of the same bell with the hammer lying against the sounding-shell, Fig. 3 is a detail view, on an enlarged scale, of the sleeve, piston, and rod specially-mentioned in the claim.
The improvement consists in improved details of construction in a call-bell.
The letter (t denotes the base of a call-bell, the same being an ornamental ring with proper feet.
The letter 1) denotes what I will term a bridge, being a sort of arch between opposite sides of the base. The hammer c is pivotally hung in cars attached to the side of the bridge and has the tappet c.
The letter (1 denotes the soundingshell. It is secured upon the top of the bridge b by the shoulder e, which is a part of the sleeve e, this last sleeve being furnished with a screw-thread at the lower end taking into a corresponding thread made in the top of the bridge I). The sleeve 6 is mortised centrally from the top down as far as the diaphragm f, and is centrally mortised from the bottom up as far as the other side of the diaphragm f.
The letter 9 denotes a piston fitting loosely in and having vertical play in the upper one of these mortises and having, as an appurtenant part, the finger-plate g. The lower end of this piston g has a small hole bored therein, and the red It is made fast to the piston g by being driven tightly into this hole just men tioned.
The letter 'i denotes a piston fitting loosely in and having vertical play in the mortise at the lower end of the sleeve 6, and it is made fast upon the rod h by being driven tightly thereupon. Sufficient space is left between the pistons g and i to allow the rod h to properly co-operate with the tappet c. When the parts are in the normal position of rest, the lower end of the rod h rests upon the top of the tappet (No model.)
0, and the weight of the hammer more than counterbalances the weight of this rod and the two pistons. By pushing down suddenly upon the finger-plate g the hammer is thrown out against thesounding-shell, causing the bell to sound.
Heretofore call-bell push-pins or pistons have been used wherein the rod or pin is can ried through the vertical sleeve on the sounding shell and lodges on the arm of the tappet. Other devices of the kind show puslrpins with pistons formed of difi'erent diameters or shouldered, and one has a slotted push-pin and a pin let through the sleeve to engage the slot and limit the reciprocations of the pushpin. My improvements consist in forming the push-pin sleeve with comparatively large bores approaching from opposite ends of the sleeve, their bottoms forming a diaphragm or bridge between the bores, which diaphragm has a smaller aperture through it than the diameter of the bores, and a push-pin formed with upper and lower parts to fit the bores of the sleeve, said parts being arranged on or connected by a pin which fits the bore of the diaphragm, thereby giving to the push-pin reliable guiding means for substantiallyits whole length, and at the same time affording in the diaphragm a substantial donbleabutting medium to resist the reciproeations of the pushpin in both directions. The rod or puslrpin can thus be made stronger and heavier than heretofore, increasing its durability, stability, and balance.
I claim as my improvement In a calhbell, the combination, with a base to support the bell, a sounding-shell, and a hammer pivotally supported in the soundingshell and provided with a tappet-arm, of a push-pin sleeve, 6, formed with a diaphragm, f, having a central aperture, and the push-pin h, fitted to reciprocate through the aperture in the diaphragm, and provided with pistons g 71, arranged with a space between their approaching ends, whereby the strokes of the push-pin are limited in both directions, substantially as described.
