MOUNTING OF ELECTRIC BELLS.

SPECIFICATION forming part Of Letters Patent N0. 694,51 1, dated March 4, 1902.

Application filed March 5, 1901. 'Seiial No. 49,885. (No model.)

To aZZ whom, it may concern:

Be it known that I, CHARLES WoITrE- QUAND, a citizen of the Republic of France, residing at 83 Oours dOrleans, Oharleville, in the Republic of France, have invented a certain new'and useful Improvement in Electrio-Bell Mounts or Supports, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a mount for electric bells of a new, simple, and cheap form of construction; and to such ends the same consists in substance of a base-plate provided with two core-pieces formed intogral therewith of magnetizable materialadapted to receive the magnet-coils, a support for the bell-hammer, and a support for the bell formed integral with the base-plate, a cover of a box-form having a slot adapted to receive the bell-hammer lever, means for re- .movably securing the cover to the front side of the base-plate, and a back plate of insulating material for closing the casing at the rear, and means for securing the same in position, although it is not to be understood that my invention is limited to a device necessarily comprising at once all the devices and parts before mentioned, as the same consists in the construction of certain devices and parts and the combination and arrangement of certain devices and parts, all as hereinafter more specifically set forth in the description and pointed out in the claims.

Said invention is fully shown and described in the following specification, of which the accompanying drawing forms a part, wherein similar letters of reference designate like or equivalent parts wherever found throughout the several views, and in which Figure 1 is a front View of my improved electric-bell mount or support. Fig. 2 is a side view thereof looking from the left. Fig. 3 is a rear view of the same, the back plate of insulating material being removed and the energizing magnet-coils being shown in position upon the standards or core-pieces energized by them. Fig. 4 is a side view of such support or mount in section on the line A B of Fig. 3 looking from the left, the magnetcoils being shown in dotted lines and the belltion.

portion of the base-plate, showing an adjustable form of hammer-supporting lug by the use of which the hammer may be adjusted to various positions Within wide limits.

' Referring to the drawings, it will be seen that the metal mount consists of magnetizable metal cast in a single piece and comprising the cores b for the electromagnet-coils supported by a lug x, extending at rightangles to the baseplate, the post 0 for the bell with screw-threaded end (1 for the reception of the securing-nut, the angle-plate e for supporting the armature bell-hammer lever, the orifices f for the fastenings of the cover, the lugs g for suspending the bell on the wall, the holes h for the binding screws or terminals, and the hole i for the regulation to which base-plate is secured, so as to cover the lug 00 and cores b, a box-like cover- I piece Z, having'side lugs, into which screw round-headed screws m, the heads of which pass through the enlarged upper portions of the slots f and the stud portions of which then drop in the narrow lower portions of the slots f, so as to hold the cover Zin position on the base-plate in such manner that the same may be removed by the hand without manipulation of any screws for the purpose of inspecting the mechanism. As is shown in Fig. 4, the angle-plate e, which supports the bell hammer armature and lever, may be made removable and adjustable, as shown in Fig. 6, being adj ustably mounted upon a plate 0, cast integral with the base-plate a. The rear of the base-plate is covered usually with a back plate p of insulating material, such as Vulcanized fiber, which is usually held in place-by fitting snugly at the sides against the walls of the rear cavity of the base-plate and by means of thebinding-screws, (not shown,) which pass through such plate 1) and through the holes h of the base-plate a, such plate 19 also serving to insulate such bindingposts from one another and the plate a.

The bell-mount, as hereinbefore described,

may also be made of non-magnetic metal and provided with a separate electromagnet fastened thereto.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a mount for electric bells abase-plate constructed entirely of metal, covered at its rear with a vulcanized-fiber plate, comprised of a single piece of metal formed integral with the cores of the electromagnet, and connected therewith bya lug supporting the cores extending at right angles to the plate, a support for the regulating-screw, a post for the bell, and lugs for suspending the base-plate, the said base-plate being formed with holes for the passage of the conducting-wires and holes for securing the cover, substantially as shown and described.

2. A base-plate for electric -be'll mounts formed of magnetizable metal cast in a single piece and comprising cores 1) for the electro magnetic coils extending from the side toward the center of the base-plate, and a bellpost, a bell-hammer armature lever-supporting lug, the base-plate being also provided with orifices for securing the cover thereon and for the reception of binding-screws, substantially as shown and described.

3. A base-plate for electric-bell mounts comprising a lug :20 extending at a right angle to the plate, and two core-pieces I) Z) extending from the lug toward the center of the baseplate parallel therewith, and at right angles to the lug, the base-plate, lug and core-pieces being formed of one piece of metal, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 16th day of February, 1901.

CHARLES \VOITTEQUAND.
