The invention consists essentially of the novel features of construction pointed out broadly and specifically in the claim for novelty following a description containing ail-explanation in detail of an acceptable form of the invention.
the passage of motor vehicles and other conveyances in thoroughfares where pedestrians and other obstacles are in the way of the progress of the vehicle, and at the same time'produce a sound that is not discordant or alarming andtherefore eliminate the shock that frequently holds. the
pedestrian or animal spellbound in the path of the vehicle; to construct theapparatus in such a manner that will enable the operator to bring forth a sound from the horn, in single tones or in chords 'as maybe found desirable, and further in accomplishing this purpose avoid complications in the mechanism and the consequences thereof in regard tofailure and repairs; to. reduce 7 the cost'of production to the minimum-so that horns of a musical type may be universally used, thus materially minimizing the dangers to life and property; and generally to provide a safe, durable and eflicient signal ,hor'n, saleable at a reasonable price to theconsumer.
In the drawings, Figure 1 is a plan view of the sound producing parts, showing the arrangement of the reeds.v V r Figure 2 is a'plan View showing theother side of the same base and the electro-magnets mounted thereon. Figure 3 is a cross sectional view of the base plate illustrated in Figures 1 and 2.

Like numerals of reference indicate corresponding parts in the variousfigures. v v
' Referring to 'the drawings, the base, indicated I by the numeral 15 is preferably of brass, though it may be of. other non-magnetic metal. On the one sideiof the base, the electro-magnets 16, 17 'and 18 are mounted and the cores 19 within the coils 20 of these magnets extend through the base 15, andare splayed over said base forming the magnet heads 21'. a
in-the sound, producing meansfas desired; ,5 I
The objects of the invention are to facilitate:
- I The electro-magnets 16, 1'7; and 18ja're preferablyv in a three cornerarrangement, though they may be set. in the base as desired, and further there 7 maybe anyilesser or greaternumber of. magnets The reeds 22, 23 and 24 are mounted between the conducting blocks 25 and insulating strips 26 which are fixedly secured in each instance by the screws 27 and 28 extending through the insulated bushings 29, and 30.- These reeds 22, 23 and 5 s w 24 extend outwardly from'their mountings over and beyond the core heads of the magnets l6, l7
and 18 respectively, andform spring armatures attracted by the'magnetized cores l9.
The contact arms 31, 32 and 33 are secured on the insulating strips 26 by the same screws 27 and ,28 above the reeds 22, 2 3 and 24 respectively, and
.in an electrical circuit energized at will by an electrical battery and immediately thatthis circuit is energized and vibration begins, that is to say, the reed in each instance is drawntothe core of an electro-magnet and vibrates back and forth between the magnet core and its contact arm, consequently this reed is interruptedly connected through to the diaphragm which is at I theother end of the magnet core, which provides the necessary fluctuations in the current to sound 7 the horn and as the several reeds are of different 1 lengths andadjustable in regard to their vibratory movements, the sounds emitted will be governedaccordingly. a v v I a The wiring 40 extends to'the' common contactv 41 of the operating switch and this common contact is connected through the spring 42 to the contact 43 on the button 44.
' Y The switchcontaots 45, 46, and 47 are respec-'*' tively connected to the three reeds 22, 23 and 24 by the wires 48, through the arms3l, 32 and 33,
consequently the operation ofthe'reeds may be separate or together; g r I The wiring 49 continues from the terminals 3'7 to the coils 20 respectively and from said coils to the make and break arms, thus completing a circuit in which the reeds become the trembling armatures in the make and break movement on the energization of the electric circuits.
The efiect of this vibration is carried through the cores 19, which are placed in proximity to the diaphragm secured on the posts. 51 and spaced from the cores 19 by the spools secured to said posts by the nuts 53.
The base 15 is secured in the casing 54' with its diaphragm and electro-magnetical attachments and this casing is fastened to the small end of the horn 55 from which the sound is,
emitted. p
In the operation of this invention the operator presses the button to brilfkgvone, 'two or more notes into the sound produced as may be desirable, and in doing this, one or more of the switch v contacts is brought into engagement with the button contact, and this through its common con- U nection with the battery energizes the electric circuit, including-the make and break arm-- or a'rmsand oneor more reeds as well as the coils of the magnets r The consequence-of this is thatthe reeds, where they are-sounded together, operate as independm-agnets will actuate the ent vibrators held independently at the ends and yet coact with'the armatures as circuit interrupt-1 ers, which insures vibration and this vibration is communicated through the cores 19 to the diaphragm, which vibrates in unison and causes the emission of the musical tones emanating from the reeds.
It) is obvious that these tones can be chosen'b y the'selectionof thereedsjas tolength and other properties and further that the depth of the tone may be affected by the arrangement of the parts inrespect to one another, 7
What I claim is: r I
In a signal horn; a plurality of electro-magnets mounted on a supporting plate with their poles projecting therethrough, a single diaphragm mounted near one pole of each of .said magnets, interrupter mechanism for the circuit of each of themagnets mounted on the supporting plate and actuated by the magnet whose circuit it controls said interrupter mechanism being tuned. to differenthfrequenciessothat each ofixthe: electrodiaphragm at a difierent frequency. 1 a e 7 MQRSE ROBB.
