JOSEPH H. HUNTER, OF PITTSBURG, PENNSYLVANIA.
ELECTRIC CHIME OR B ELL.
SPECIFICATION forming partof Letters Patent No. 476,463, dated J 11119 7, 1892. Application filed February 29, 1892' Serial No. 423,138. (No model.)
To aZZ whom it may concern.-
Be it known that I, JOSEPH H. 'HUNTER. a citizen of the United States, residing in Pittsburg, in the countyof Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Electric Chimes or Bells, of which the following is a specification.
This invention has relation to electric callbclls or alarm apparatus, and is adapted to be used ordinarily where other electric callbells or alarms are used.
The object of the invention is to provide a device of this kind in which the tone of the bell or chime is produced by causing it to move bodily against the head of the magnet.
The invention consists of the details of construction, which will hereinafter be described, and pointed out in the claims.
Intheaccompanyingdrawings, Figure l is an elevation of my improved apparatus with the circuits, and Fig. 2 is a modification of the same.
A represents a base or other support to which is attached an electro-magnet B.
Z) Z) are two binding-posts to which the terminals of the magnet-coils are connected.
0. represents a hollow post fixed to the base and having a rod a telescoped into its upper end and with a set-screw a for regulating the height of said rod. To the upper end of the rod is secured the end of a flat steel spiral c. The spiral consists of several turns, all in the same plane, and it is located directly above the pole of the electro-magnet with the outer turn within attractive distance.
G represents a generator of alternatingcurrents, the circuit of which is represented by g g. From this circuit a branch g, containing a circuit-closer is led to the bindingposts I) h. hen the branch circuit is closed, the alternating currents, which flow in the magnet B,cause alternate attractions and repnlsions of the spirahand thereby cause it to successively strike the pole of the magnet, producing a vibrating musical sound or tone, which is much more pleasant to hear and is more penetrating than that of the ordinary stroke-bell, being similar to the tone of a cathedral chime.
In Fig. 2 is shown a modification consisting of a magnet supported upon its side with an ordinary gong adjustably located near and operated by one pole and an armature and circuit-interrupter operated by the other pole. A spring f retracts the gong after it has been attracted by the magnet, the gong being mounted on a pivoted arm f for that purpose. In this case a continuous current would be used and the same caused to pulsate or flow through the magnet intermittently by means of the usual circuit-interrupter f. The tone would be similar to that produced by a hammer striking the gong, and if the circuit-interrupter was omitted the apparatus would be a single-stroke bell.
It is obvious that either an alternating, intermittent, or pulsatory current may be used with this apparatus, and that the invention is not limited to the nature of the current. The preferred form is that shown in Fig. 1, and instead of the spring being made of steel it may be of any other sound-producing material and carry an armature (shown it dotted lines) to be acted upon by the magnet.
Having thus described my invention, I claim 1. The combination, with an electro-magnet, of a chime or gong located near the pole of the magnet and movable bodily toward and against the same under the attraction of the magnet, for the purpose set forth.
2. A call-bell or alarm consisting of the combination of an electro-magnet and a sound ing spiral located within attractive distance of the magnet and adapted to be moved bodily against the magnet to produce a sound.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
JOSEPH n. HUNTER.
