Description

APPLIOATION FILED MAY 19. 1906.`
. WALTER C.
HILL, OF LONDON, ENGLAND.
WATER-TIGHT ELECTRIC BELL.
Specicaton of Letters Patent.
Patented Sept. 3, 197.
Application filed May 19, 1906. Serial No. 817,717.
To all whom it may concern:
lic it known that I, WALTER C. HILL, a subject ot' the Kingdomof Great Britain, residing in London, England, have invented certain new and useful Impreve ments in WatereTight Electric Bells, of which the iol-l lowing is a specification. i
My invention relates to electrically actuated bells or alarms wherein the electric striking mechanism is inclosed within a water-tight metallic casing which forms the sounder or bell,l and my improvements consist in certain particulars of construction which are hereinafter pointed out and described.
ln the drawings Figure l is a side elevation of one of my improved bells, with a portion of the case broken away to show the interior mechanism, and Fig. '2 is a vertical cross-sectional View of the same taken on the line fr, :1; oi' Fig. l, the casing however not being broken away as in that figure.
Similar letters of reference designate similar parts in both the figures.
A is the bell, which is lormed of brass, bell metal, or other suitable material, either cast as a whole or stamped or spun in halves and afterward united, as shown in the drawings, the two corresponding halves being soldered togetherand to the inner band a. The head-piece l5 is formed oi' a suitable insulating material, such as vulcanite, red iiber, wood or composition, and it is firmly secured to the bcll A by screws C C passing through the head-piece and threaded into the bell, thus making a close, water-tight joint between the head-piece and the bell. lA rod D, is insertedin the head-piece, its upper end being secured to Ia suitable bracket E, connection being made between its lower end and one end, f, ol' the electro magnetic coil F, by
means of a contact screw c. A collar G, is secured around the neck of the head-piece B by means of screws g g passing through the collar and head-piece and threaded into and carrying an electro magnet H.
` The electric circuit is continued from the end f of the clcclro magnetic coil through a screw t', and a makennd-breztk contact spring l, supported by insulation c 'States is z upon the neck of the screw K which passes irccly through the armature J and into the magnet ll, and by a connection from the armature spring J, through a suitable' conductor j, to the electro magnet Il, and completed through the screws y y, and the coll-.tr G, to which is attached the flexible lead y, the other lead c being attached to the bracket E.
By means of my improvements I obtain au airtight and Water-light bell or alarm, the operative mechanism whereof is entirely contained within the sealed case of bcll; and wherein the lcxiblc leads are not carried into the bell itself, which is objcctionablc because ol' the danger oi' breaking the internal connections-by rough 'handling or abnormal, accidental strains on the terminal wires, but in which the electric circuit is carried through the rigid screws which arc employed to con- -nect thc electrical mechanism with the non-conducting head-piece and to sustain th'e'device in a suitable position. l
The case or bell A, being carried by the non -conducting head-piece B, is outside of the electrical circuit; and l thereby avoid the danger of short-circuiting the current, which is likely to happen where the casing itself forms part ol' the electrical circuit.
Having thus described my invention, what I claim and desire to secure by Letters Patent of thc United 'lhcl combination, in an electrical alarm, of a non conducting head-piece provided with electrical conductors passing therethrough, electrical striking mechanism snpportef] b v said head piece, and a hollow cylinder with Hat, closed ends forming a resonant bell casing' and having :in opening' through its circumference to permit the insertion `o1" said striking mechanism theretln'ough, said opening being.;l closed by said head piece whereby said bell-casing is carried free from other Contact and outside ol' (he electric circuit and forms a hermetcally closed chamber comA pleiely inclosing said striking' mechanism and adapted to' he rung thereby.
