'IMPROVED DooR BELL 0R GoNc.
Specification forming part of Letters Patent No. l18,234, dated June 13, 1865.
To all whom it may concerns y Be it known that I, A. G. DEXTER, of San Francisco, in the county ot' San Francisco and State of California, have invented a new and Improved Door-Gong; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference bein g had to the accompanying drawings, forming part of this specification, in which- Figure l is a front or face view ofthe outer part of my invention applied to a door; Fig. 2, a rear vView of the inner portion of the same at the inner side of the door; Fig. 3, a vertical section of a portion of the door and thein- Vvention applied thereto, x a', Fig. 2, indicating the line of section; Fig. 4, a vertical section of a portion ofthe invention,taken in the line at 5v, Fig. 2.
Similar letters of reference indicate corre-w sponding parts.
This invention relates to a new and improved gong applied to a door in such a manner as to serve as an improvement on the ordinary door-bell, it being more readily applied, less liable to get out ot' repair, and sufficiently sonorous to be heard all through the house.
A represents a portion of a door to which the invention is applied, and B is a lever, which passes through a lnortise, a, in the door and works on a fulcrum pin, b, which passes through a metal cap, C, secured to the outer side of the door in line with the mortise a. The outer end of the lever B has a plate, D, attached to it, on the outer side of which the name of the occupant of the house may be engrayed, and also the numberV of the house. The end of the leverB at the inner side ofthe door is connected by a rod, E, with a bent lever, F, which has its fulcrnm-pin b in a metal frame, G, screwedto the inner side of the door, and the upper end of this leverF is connected to one end of a spiral spring, H, the opposite end of which is connected to the frame G atA c. (See Fig. 2.) This springH has a tendency to keep the inner end of the lever B drawn down, so that the plate D at its upper end will bear against the upper edge of the cap C,and
L having a tendency to keep the hammer near the gong and the shaft J in contact with a stop, e, on frame G.
In the upper end of the bent lever F there is iitted on a pivot, j', a plate, M, which has` a spiral spring, g, bearing against its under side, said spring having a tendency to keep the end of the plate M opposite to the end where the pivot f passes through forced upward and above a shoulder, h, on the hammer-shaft J, the upper and disengaged end of the plate Mv being slightly rounded, as shown at@ in Fig.2. From the above description it will be seen that by pressing against the lower end of the plate D the inner end of lever B will be forced upward and the bent leverF actuated so that the plate M will come in contact with the shoulder l1. of the hammer shaft J and force the hammer K out from the gong until the shoulder 7L, under the tension of the spring L, will slip back over the rounded corner of plate M, the spring bringing the hammer in contact with the gong.
The bent lever F is brought back to its original position by the sprin g H, the plate M, on account of resting on the spring g, being allowed to yield, so that it may pass under the shoulder h of the hammer-shaft.
Thus by this simple arrangement l obtain a gong for a door, which may be cheaply con structed, readily applied, and which will not be liable to get out of repair.
I claim as new and desire to secure by LetA ters Patent 1. A gong for a door, the hammer oi' which is operated throughthe medium of a plate or handle at the outer side of the door, so arranged or connected with levers and the hammershaft that the latter will be actuated and. the gong sounded by pressing said plate or handle in a direction toward the door, substantially as herein set forth.
2. The arrangement of the hammer-shaft J, bent lever F, with yielding plate M attached,
lever B, andplate or handle D, or its equivalent, with the springs H L and gong I, substantially as and for the purpose set forth.
A. G. DEXTER. Witnesses:
