HERBERT S. PULLMAN, OF MERIDEN, CONNECTICUT;

BELL. 1

srnerrrearron forming part of Letters Patent No. 654,324, dated. July 24, 1906.

Application filed February 26,1900. Serial No. 6,488. (No man.)

To all whom it may concern:

Be it known that I, HERBERT S. PULL'MAN, a citizen of the United States, and a resident of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Bells, of which thefollowing is a specification.

My invention relates to the general class of alarm or call bells; and my object is to provide a striking mechanism for such bells that will produce the effect of an electric bell in the rapidly-repeated strokes of the hammer when the bell is operated. Referring to the drawings, where one form of embodying the invention in a bell is shown, forming part hereof, Figure 1 is a top or plan view of the base of the bell and the operating mechanism, the gong being removed. Fig. 2 is a view in side elevation of the bell, the gong being out in central section. Fig. 3 is a detail view, on enlarged scale, showing the ratchet-drive in central section.

In the accompanying drawings the letter a denotes the base of the bell, which may be of any convenient form with ordinary means to support the structure in proper position for use.

On the base 0. is secured a post I), the outer end of which bears a gong o, secured in any convenient manner, the post being hollow or tubular to receive the plunger 01, which has a sliding movement therein, the arm d on the plunger projecting through a slot in the side wall of the post Z).

To a fixed part of the frame of the structure and preferably on the side of the post I) a bell-crank lever e is pivoted, with its outer end 6' underlying the arm 01 on the plunger and its opposite end connected by alink f with one end of the striker-lever g. This strikerlever gis pivoted to the base of the bell, as at 77., and has on its outer end a segmental gear 9, which is in mesh with a pinion t'. This pinion is secured to the hub 7c of the ratchetwheel 70, which is pivotally supported on the post Z on the base a. On the same hub 76 an escapement-wheel m is loosely mounted, so as to turn freely in one direction while held from any sliding movement along the hub, and by means of the spring-pawl n pivoted to the side of this escapement-wheel m the ratchet-wheel 7c is connected to the wheel m,

so as to turn with it in the reverse direction. A verge o, with pallet-teeth in suitable engagement with the escapement wheel, is mounted on arock-shaft to which the arm 19" of the bell striker or hammer p is secured. When the escapement-wheel is forcibly rojtated in one direction, the verge will be caused to vibrate rapidly and the gong to sound. The striker-lever is held in the proper posi tion of rest by means of a spring 7', one end of which is anchored to the base and the other attached to the lower end of the bellcrank lever, as shown in Fig. 1 of the drawings.

To operate the bell, pressure is applied to the cap of the plunger d, so that the arm d thrusts against the end e of the bell-crank le-' ver, tilts the latter, and through the link f 6 no reverse movement, the ratchet-wheel turning freely under the pawl in this resetting of the mechanism.

What I claim as my invention, and desire to secure by Letters Patent, is

l. A bell-base, bell-striking mechanism supported by the base and including a pinion, a hollow post supported on the base, a strikerlever pivoted to the base with one end having a segmental gear meshing with said pinion, a bell-crank lever pivoted on the post, a link connecting the bell-crank lever with the striker-lever, a plunger supported by the post and having an arm overlying an arm on the bell-crank lever and a gong secured to the 0st. p 2. A bell-base, bell-striking mechanism supported by the base and including a single pinion, a hollow post supported on the base, a U-shaped lever with its branches lying on opposite sides of said post, one branch bearing a segmental gear meshing with said pinion, and the other branch forming a connection for a link, a bell-crank lever pivoted on the post, a link connecting the bell-crank lever with the U-shaped lever, a plunger sup and an escapement-wheel, a fixed stud, a

ratchet-wheel mounted to turn on the stud and having an elongated hub,the escapelnentto wheel mounted to turn on the hub, a pawl connecting the ratchet-Wheel and the escape ment-Wheel, a pinion secured to the hub of the ratchet-Wheel, a striker-lever in engagement with said pinion, and means for operating the striker-lever.
