CHARLES HENZEL, OF NEXV YORK, N. Y.
ELECTRlC-SIGNAL BELL.
SPECII-ICATIOIQF forming part of Letters Patent No. 318,472, dated May 26,1885.
Application filed March 16, 1885.
To ctZZ whom it may concern:
Be it known that I, CHARLES IIEXZEL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Electro-Vibrating Call or Signal Bells, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to electro-vibrating call or signal bells, and it has for its object such improvements on the devices of this character 110w in use as will render the bell capable of indicating from what point the call or alarm is sounded; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claim.
In the accompanyingdrawings, which il' lnstrate my invention, Figure 1 is an elevation of my improved apparatus, one side of the inclosing-case being removed so as to disclose the interior mechanism. Fig. 2 is a transverse vertical sectional view taken on the line 00 x of Fig. 1. Fig. 8 is a detailed perspective view.
A represents an inclosing'case, to which are secured the insulated binding-posts a Z) and the electromagnets B.
6 represents a vibrating armature, which operates in front of the cores of the electromagnets in the usual manner. This armature has on one side a projecting stud, c. A contact-spring, D, is secured to the armature, and forms one side of the circuit-breaker, the
other side of which is formed by the point of the screw E, which passes through an insulating-bushing, F, that is secured to the case.
G represents a spring, that bears against the armature for the purpose of keeping the contact-spring D normally in contact with the point of the screw E. The lower end of this spring bears against the bottom of the box, which, as here shown, is made of metal. A gong, F, is carried by a post, f, that rises from the upper side of the box, and to the up per end of the armature is secured an arm, G, that extends up through a slotted opening, 9, that is made in the upper side of the box, and terminates in a hammer, H, which strikes the gong when the armature is at- (No model.)
the apparatus is in circuit. A screw, k, passes through the lowerside of the frame K,and projects slightly beyond the frame, as shown.
Loosely mounted on one end of the shaft or rod I, and in contact with one side of the frame K, is a spurred pinion, L, from the inner side of which projects a stud, Z, that euters a quarter-circular slot, It, that is made in one side of the frame K. A rack-bar, M, has its lower portion slotted and secured to one side of the box by a screw, m, that passes through the slot m. The upper end of the raclcbar is reduced, as at m and passes through an opening that is made in the upper side of the box. This rack-bar meshes with the pinion L, Vhen the rack-bar is raised vertically,the pinion is partly rotated, and its stud Z bears against one end of the slot k and raises the frame K to a horizontal position, and the frame is retained in this position by the screw It, the point of which rests upon the stud c of the armature. IVhen the armature is attracted, the gong is sounded and the frame K dropped to a vertical position, and the name or number of the place or door with which the apparatus is in circuit shows through the opening (I. The circuit is as fol- .lows: From binding'post a through wire 8 to coils e,- thence by wire 6 to bottom of box, and thence through spring G, armature G, and contact-spring D to screw E, and from thence through wire 1) to binding post b. If desired, the bell may be discarded, and only the frame carrying the numbered or lettered card used.
Having thus described my invention, I clai 111- In electric-bell apparatus, the combination of a case inclosing and carrying the same, and having an opening in one of its sides, the armature having a projecting stud or shoulder, the hinged frame having the quarter-circular slot, the loose pinion journaled in line with I my own I have hereto affixed my signaturein the hinged end of the frame and having a stud the presence of two witnesses.
that enters the slot in the hinged frame and the rack-bar that, meshes with the loose pin- CHARLES HENZEL' 5 ion for the purpose set forth, substantially as Witnesses:
