V UNITED STATES JOHN W. COX, OF BARABOO, WISCONSIN.
COMBINED BELL AND BUZZER.
Application field June 25, 1921. Serial No. 480,343.
This invention relates toa combined bell and buzzer and it has for its object to provide means mounted upon a common supporting frame for electrically ringing a bell or for electrically actuating a buzzer to there'by produce distinctive sounds which would indicate to the hearer the location of the switch which has been closed to create such sound.
It is common practice in the installation of door bells and the like, to provide a bell of one kind for the front door and a bell of another kind for the rear door, or a bell for the front door and a buzzer for the rear door, so that the person answering the signal will know whether to go to the front door or to the rear door.
It has ordinarily been customary to provide entirely separate units for the purpose indicated. This has necessitated the installation of considerable additional wiring. A few constructions have been proposed which incorporates the buzzer and the bell in a single mechanism, but these have usually been complicated and expensive to manufacture. It is the primary purpose of the present invention to provide a structure of the character indicated which will be of the utmost simplicity and in which the parts are so correlated and combined that the device may be manufactured at a very small cost.
Further objects and advantages of the invention will be set forth in the detailed description which follows. v
V In the accompanying drawing:
' Fig. 1 is a dlagrammatic-plan view of a device constructed in accordance with the invention;
Fig. 2 is an underside plan view thereof; and
Fig. 3 is an end elevation of the insulating strip hereinafter described and th brackets supporting the same. i
Like numerals designate corresponding parts throughout the several figures of the drawing.
In the drawing 5 designates a frame, and
of a part 6 a bell of a usual and well known construction. The hammer 7 of the bell is-carried by an armature 8 that is moved when the cores 9 of magnets 10 are energized.
The buzzer consists of an armature 11 that is attractedby the cores 12 of magnets 13,
when said magnets are energized.
The present invention provides very simple and inexpensive means for mounting the magnetswith respect to the frame. This consists of an insulating strip 14- supported fronr the base 5, at 15, through the medium of out-turned feet or ears. The armatures 8 and 11 carry springs 16 and 17 of a usual and well known type and these springs make contact, when the magnets are to bee-nergized, with posts 18 and 19. The lower end of these posts pass through the frame 5 and are attached to conductors 20 and 21 which are the terminal ends of the windings of the magnets 10 and 13 respectively.
The rear ends of the armatures 8 and 11 are carried by posts 22 and 23, the lower end of which are connected by conductors 24 and 25 with a common binding post 26.
Binding posts 27 and 28 are connected to conductors 29 and 30 respectively. The conductors 29 and 30 constitute the terminals of the other end of the windings of the'magnets 10 and 13 respectively.
By virtue of the arrangement shown, a connection from a battery, such as is indicated at 31, serves to constitute one side of the line to both the bell and the buzzer.
A buzzer controlling push button 32 which, in use, is usually located at the rear door of a residence, is connected at 33 to the other battery-lead 34. The other side oft-his push button is connected by a conductor 35 with the binding post 28. One side of the bell controlling push button 36 is connected by a conductor 37 with the binding post 27, while the other side of said connected by a conductor 39 with the battery lead 3f.l:. j
A box like cover 40 common in electric bell construction covers and protects the magnets. The operation of the device will be readily apparent to' those skilled in the art It is to be understood that the invention is not limited to the precise construction set forth but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims. I
ush button is Having described my invention, what .I claim is:
1. A combined bell and buzzer comprising a supporting frame, a centrally disposed insulating strip mounted upon edge upon said frame, independent ma nets supported upon and projecting from t e ,opposite sides of said strip, a bell supported from said frame, a hammer carrying armature coacting with one set of,magnets and a buzzer armature coacting with the other set of magnets.
2. A combined bell and buzzer comprising a supporting frame, a narrow plate-like Y strip of insulating material, brackets secured to said insulating material and to the frame 15 and supporting said plate-like strip on edge and longitudinally of the frame, a pair of independent magnets projecting laterally from each side of the strip and supported wholly thereby, a bell supported from said frame, a hammer carrying armature coacting with the magnets at one side of the strip the hammer of which is associated with said bell and a buzzer armature coacting with the magnets upon the other side of the strip In testimony whereof I here unto aflix my signature.
