ELECTRIC BELi SPECIFICATION forming part of Letters Patent No. 353,274, dated November 23, 1885.
Application filed May 21,1886, Serial Nolli. (No model.)
To @ZZ whom it may concern.: j
Beit known that we, CHARLES A. TUCKER, residing in the town of Islip, in the county of Suffolk and State of New York, and OTTO H. HUEBEL, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and `useful Inlproveinents in Electric Bells; and we do hereby declare that the following is a full, clear, and io exact description of our invention, reference being had to the aecompanyi ng drawings, which form part of this specification.
The invention relates to bells adapted to be operated by electricity, and has for its object improvements in Structures of this character by which they will be secured against injury from dust, moisture, insects, and other substances, and whereby the parts can be easily and exactly adjusted, or taken ont of their zo case for examination and replaced without removing the case from its position on the wall, or wherever the same may be secured.
ln the drawings we show a structure containing cur invention, in which Figure l is a i'ront elevation. Fig. 2 is a back elevation. Fig. 3 is a section through the linex n: of Fig.2. Similar letters of reference indicate like parts in all the drawings.
Heretol'ore the operating parts of such bells have been usually Secured to the wall, either on a board or within a box which has been there fastened directly, So that when access to such parts was desired for any purpose either the whole structure had to be loosened from Yits position, and taken down and then again secured to its position, or the parts had to be examined in the place where the structure was located, these requirements being often very inconvenient. A
XVe arrange the operating parts of our bell in a case consisting oi'an inclosing-franie, a a, provided with a suitable gong-standard, as b, which may all be made in one piece, and having suitable means for attachment in position, 5 as by means of the screw-holes c c,- and this frame may be made oi' any Suitable material, preferably cast metal. This frame forms an inclosure for the sides, bottoni, and part of the top; bntno portion of the operating mech- 50 anism is attached to this frame, so that when this part of the structure is once fixed in its proper position it need never be removed therefrom for any purpose of adjusting or eX- annining the parts, die.
The operating part-s of the bell are all se- 5 5 cured to the front A, which is secured to the frame a a, and held in position there in any eonvenientinanner, as by means of a screw, c, holding it to the supportf. Such Support f may conveniently be formed as a part of the 6c. frame (La. Thus the front A, with its attached operating mechanism, may be taken ont of the frame by simply withdrawing the screw e.
The front A. is made of any suitable material, cast metal being convenient and cheap. On its inner face is secured a standard, g, which may be an integral part of it. To this 'standard a magnet-yoke, t', is properly fastened, and to this yoke suitable magnets, m m, are secured. A vibrating armature, j, carrying thehammer-rodj, is attached tothe springstrip k at the proper distance from the magnets. This Springsi'rip 7i: is secured to a Slotted support, n, which is held in place by the screw o in the slot, and by means of this arrangement thc position of the armature relative to the magnets can be exactly and easily regulated, without twisting or bending the spring-strip k l'or that purpose, by Simply loosening the screw o, moving the armature to the desired position, and then tightening the screw. The free end of the strip k operates as the circuit-breaker. A suitable metal st rip, It, which is in electrical Contact with one of the magnet` wires, as shown in Fig. 3, is secu red to the in- S5 sulated spool-heads ol" the magnet m, having its free end ilexible and bent down by the Side of the free end of the circuit-breaker if, and this i'ree end of the strip 7L is adj Listed to spring outward and away from the Circuitbreaker when free, but it is held tothe desired position -by means of an eccentric, Z, which is adjusted to bear against it. @n the face nearest the face oi' the circuit-breaker of this end of the strip h is secured al suitable coniaet-point, r, Fig. 2. This contactpoint r is adjusted in any desired position relative to the Contact` breaker by means of the eccentric Z, which is secured to the inner end oi' the set-screw s. This screw s passes through. the front A of the case, and is provided with a friction-nut, a, whereby it is secured against disarrangenient when the eccentric has been turned to the desired position. rllhe screw o, which secures the cireuit-breaker k and vibrating armature y', enters the binding-post t, and by means of it the electrical circuit is made. The circuit is made from binding-post t through magnetwires o, strip Z1, contactpoint r, strip Zr, screw o, to binding-post t.
Vhen the face A is not made of uon'conducting material, one ofthe binding-posts, as t, must be insulated therefrom, and the eccentricZ must likewise be insulated, as by nia-king it ot' hard rubber or other vsuitable non-conducting material.
To exclude foreign substances, we attach a protecting-hood, w, to the hammer-rod j. rlhis may be made of silk or other suitable material that will not interfere with the vibrating ofthe rod, and its lower edges are cemented or otherwise suitably secured to the top of the part A, around the slot through which the rod passes, andthe upper edges are fastened tightly to the hammer rod itself'. It will be seen that this device will protect the structure whether it be placed in position with the gong up or down. If water-prooi" material and cement are used, the hood will also prevent moisture entering the slot.
Vhen the bell is to be secured to a dry,
sound wall or other proper place, the back may be left open, if desired; but when there is any dampness or irregularity in the surface upon which the frame is to be fastened the back of the case is protected by any suitable covering, y, (shown broken away in Fig. 2,) and the whole exterior back surlace properly coated with some moisture-proofcomposition, which will protect the parts, and make the structure much more enduring than when the back is left open.
By this disposition ot the parts and their peculiarstructure, as described, many advantages are obtained. The inclosing-case for the mechanism, once iixed in position on the wall, Sie., need never be removed therefrom for the purpose of obtaining access to any of the operating parts, the operating parts being all adjusted on a dat plate, A. When the same is taken from the case, easy access is had to all the parts. The use ot" tension springs is avoided. The adjusting-screw s is without the case, and on its front, where it can be easily reached. By means of the slotted support a the armature j may be quickly and easily ad- 55 justed parallel to the face of the magnet-cores by one screw, o, and by means of the hood w, securely incasing the hammer-rod and at-. tached to the upper surface of the plate A, the
operating parts are fully protected from foreign substances.
Having thus described our invention, we claim as newl. An electric-bell apparatus provided with a case consisting of a front, A, carrying the op erating parts, in combination with the inclosingframe c a., substantially as described and shown.
2. The frame a a, adapted to inclose and protect the operating mechanism of an electric bell, in combination with a removable front, A, supporting all the operating parts, substantially as described and shown.
3. The frame a c, adapted to inelose and protect the operating mechanism of an electric bell, and a cover-plate carrying the operating parts, in combination with the inelosingback y, substantially as described and shown.
4. The frame a a, back y, and removable front A, in combination with the operating parts of an electric bell secured to such front A, substantially as described and shown.
5. The combination of the armaturej, strip 7c, and the support a, slotted at right angles tof the strip Zt, in combination with au adjustingscrew, o, substantiallyas described and shown. 8
6. The combination of the eccentric Z, and screw s, and a suitable contact-point, as the stri p le, substantially as set forth.
7. rlhe combinatiomwith an adjustable contact-screw passing through the front of the case, of an eccentric, Z, formed of non-conduct ing material, substantially as described.
8. The combination ot' the magnet-wire c, terminating in a suitable contact-point, as r, with the adjusting-eccentric Z, adapted to be operated from the front of the case A, substantially as set forth.
9. In an electric-bell apparatus, the combination of the Vibrating hammer-rod j and hood 10, securely attached to the hammer-rod and to the plate A, and adapted to exclude foreign substances from the interior of the inclosing-case in whatever position the same may be placed, substantially as described and shown.
10. An electric-bell apparatus consisting of the case a a, front A, suitable magnets, rod j, armature j, and adjustable standard a, in combination with the strip Zzr and screw s, carrying the eccentric Z, substantially and shown.
