Specification of Letters Patent.
Patented Aug. 31, 1924).
Application filed March 21. 1919. Serial No. 284.028.
T 0 all whom it may concern:
Be it known that I, GEORGE F. VoiGHr, a citizen of the United States, and resident of the city and county of San Francisco, :ltate of California, have invented a new and Improved Horn, of which the following is a specification.
My invention relates to a type of horn adapted to be carried by a road vehicle or the like, operable for giving phonetic warning signals, and in which a diaphragm is vibrated by mechanical means.
An objectof my invention is to provide a horn having a supporting bracket adapted to be rigidly secured to a portion of the vehicle, the bracket pivotally supporting the horn, and the horn movably engageable with a portion of the bracket for operating mechanism adapted to vibrate the diaphragm.
Another object of the invention is to provide a horn free from anyopening in its top or end walls of I the casing through which project operating levers or the like. Such an opening, or openings, when the vehicle to which the horn may be attached is being washed, or when the-horn is exposed to rain, is liable to permit water or moisture to enter to the detriment of the working parts contained inside the casing.
A further object of the present invention is to eliminate the usual operating arm projecting out from the casing, which is unattractive and liable to catch on the clothing of the operator.-
Still another object is to provide a horn in which the axis of its resonator, during the operation of the horn, will oscillate, thereby changing the direction in which the sound waves emitted by the horn will travel and giving a distinctive effect to the tone of the warning.
With the foregoing and other objects and purposes in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction herein after described and claimed, it be understood that changes in the precis -en,
codiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated, more or less diagrammatically, in the accompanying drawings, wherein Figure l is a longitudinal elevation of the horn; F 2 is a longitudinal sectional view; F 1g. 3 1s a view partly in section, of the horn moved downwardly from its normal position; Fig. 4: is a sectional view on line b-b in Fig. 1; Fig. 5 is a sectional view on line c-a in Fig. l and Fig. 6 is a de tailed view in perspective of a portion of the supporting bracket.
Like numerals of reference designate like parts throughout the several views.
Referring now to the drawings in detail, 1 designates a bracket plate rigidly secured to a base 2 by means of screws 3. The base 2 may form a portion of the frame of a vehicle.
One end of the bracket 1 is struck upwardly, thereby forming a relatively short arm l having its upper or free end bifurcated and formed into a pair of spaced apart ears 5 provided with openings 6, which support the outer ends of a pivot pin 7.
8 designates the resonator, 9 the diaphragm and 10 the walls of the mechanism chamber, of a horn constructed and assembled in a manner common to the type of horn to which my horn in general belongs.
To the lower side of the resonator 8 is rigidly secured a plate 11, by means of a rivet 12. The plate is provided at one end with an opening 13 through which rotatably extends the pivot pin 7. The arrangement being such that the resonator 8 may be oscillatorily supported by the pivot pin 7.
The opposite end of the bracket 1 is also struck upwardly thereby forming a relatively long arcuated arm 14;, the upper end portion of which extends into the horn through an opening 15 in the wall 10 and is provided with a slot 16, thereby forming two oppositely disposed members 17 and 18. (See Figs. 5 and 6. In Fig. 6 the members are shown before being curved or arcuated.) The upper portion of the member 17 is provided upon its concaved side with teeth 19, which engage teeth 20 of a pinion gear 21, which is disposed centrally upon one side of a rotor'22 and is integral therewith. r
The rotor and pinion are rigidly secured to a shaft 23, which has its outer ends journaled in bushings 24. disposed in openings 25 in the Walls 10. The shaft is provided with pins 26 for restricting longitudinal movement thereof relatively to the bushm s.
llpon the periphery of the rotor 22 are teeth 27 engageable with an anvil 28 centrally disposed upon the diaphragm 9.
29 designates a projection on the upper end of the member 17 to which is secured the upper end of a contractile coil spring 30. The lower end of the spring is secured to a lip 3i struck inwardly from the wall 10 adjacent the opening 15.
a button i av secured the wall 10, and adapted to be engaged by the hand of the person operating the horn.
To operate the horn, presuming for illustration that the horn is in its normal position, which is the position of the horn as depicted in Figs. 1 and 2, the operator strikes or presses downwardly upon the button 82 thereby causing the horn to oscillate upon the pivot pin 7 and the rear end thereof to move downwardly along an arcuated line of which the pivot pin 7 is the radial point, into approximately the position shown in Fig. 3, the teeth 20 of the pinion gear 21 being in engagement with the teeth 19, the said downwardly movementof the rear end of the horn will cause the rotor 22 to rotate and the teeth 27 to impinge the anvil 28 and vibrate the diaphragm. The downwardly movement of the horn will cause the spring 30 to extend loi'igitudinally against its tension, and it is intended that the spring be made strong enough so that the tension thereof will cause the horn to oscillate back to its initial or normal position after the down stroke of the horn has been completed.
In order to facilitate the description of the horn and in defining its operation and functions, in this specification, the resonator end of the horn is designated the front end and that portion thereof on the opposite side of the diaphragm from the resonator is designated the rear end.
I claim:
1. The combination with the body portion of an oscillatory horn, embodying a resonator, a diaphragm and casing rigidly secured together, and means movable relative thereto disposed inside the casing for operatively engaging and vibrating said diaphragm, of an opening in the lower side of said casing, a bracket having one end disposed below said resonator and pivotally connected thereto and another end disposed below said casing and having a projection extending through said opening and operatively in en gagement with said means, and a spring engaging said bracket and horn adapted to yieldingly support the horn against oscillation.
2. The combination with the body portion of an oscillatory horn embodying a resonator, a diaphragm and casing, means for rigidly securing said resonator diaphragm and casing together, and movable mechanism disposed inside adapted when moved to vibrate said diaphragm, said mechanism including a toothed member, of a pivot pin disposed outside of said casing, a connection between said pin and the horn, an opening in the lower side of the casing, a bracket adapted to be rigidly secured to a base, a connection between one end of the bracket and said pivot pin, the other end of said bracket extending through said opening and provided with teeth on its free end adapted to operatively engage said toothed member.
