Patented Nov. 9, Litfiilii.
Application filed October 29, 1912. Serial No. 728,374.
To all whomz't may concern:
Be it known that I, PETER C. BURNS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Horns, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specifiaction.
My invention relates to horns and is of a special utility for use as an automobile horn.
My invention contemplates a motor driven horn of such a character in which a diaphragm is employed and a separate striker, which striker is actuated through suitable motor driven means.
In one form of the invention I prefer to mount the striker on what might be called a spring arm or resilient mounting so that the striker may be easily actuated to cause v1- bration of the main diaphragm to thereby emit the sound required.
I will explain one embodiment of my invention more in detail by reference to the accompanying drawing illustrating said embodiment, in which:
Figure l is a side View partly in section of a horn constructed in accordance with my invention; Fig. 2 is a sectional view on line aa; of Fig. 1, and Figs. 3 and 4 are details of construction.
My improved horn consists in the embodiment herein shown of a cup shaped casing 1 having a suitable cover plate 2. These two parts are held in position by means of bolts 3 which bolts serve the further purpose of holding various other parts in position as will presently appear. The cover plate 2 has a mouth 4 within which a suitable resonator or amplifier 5 is secured as is customary in devices of this kind.
I employ a motor 6 to furnish the 'motive power and this motor may be provided with binding posts 7, 7, for instance through which it receives its current by which the said motor may be operated. Rearwardly of the resonator 5 and within the casing 1 I provide a diaphragm 8, which diaphragm is held in place through the agency of the bolts 3, a distance piece or annular ring 9 intervening between this diaphragm and the inturned face of the casing 1. Back of this diaphragm I mount a striker 10, which striker is placed close to the diaphragm 8 and which striker is held in place upon a three legged strip 11, which strip 11 is also held in place through the agency of the bolts 3, a distance piece 12 being provided intermediate the elements 8 and 11 to maintain a normal separation between them. Rearwardly of the element 11 and preferably forming part of the striker 10' is a backwardly projecting lug 13. This lug is designed to be engaged by suitable mechanism driven by-the motor to thereby force the striker 10 against the diaphragm 8 so as to hit this diaphragm 8 a series of successive blows to thereby cause the said diaphragm 8 to emit a loud sound which passes out through the resonator 5. In order to cause this rapid succession of blows I mount upon the motor shaft 14 a rotatable disk 15 having projecting arms 16 as shown more in detail in Fig. 3. As this disk 15 is rapidly rotated when the motor is actuated the arms 16 engage the projection 13 and force the same toward the right (Fig. 1) to thereby force the striker 10 against the diaphragm. 8. The striker 10 will of course hit the diaphragm 8 whenever an arm 16 engages and passes beyond the projection 13. The striker it will be seen is mounted in a manner analogous to a resilient mounting and in such a way as to require a minimum of power for the movement of the striker proper.
My invention further contemplates improved means so as to simplify the adjustment frequently required between the parts 13 and 16. In order not to necessitate the longitudinal adjustment of the element 13 my invention contemplates the longitudinal adjustment of the disk 15 merely through the adjustment of the motor 6 relative to thecasing l and this I accomplish by having the motor casing provided with a protruding cylindrical element 17 having screw threads on its exterior periphery. This engages the interior of the rearwardly extending mouth 18 of the casing 1, which mouth 18 has screw threads on its interior periphery. It will thus be seen that by rotating the motor casing relative to the casing 1 the motor is moved longitudinally and thereby carries with it the disk 15 and its projections 16. A set screw 19 is provided to hold these two parts 17 and 18 in position after the proper adjustment has been made. The design of the parts is of course such that the element 13 will not bend maplace.
terially when it is actuated by the arms 16 but will rather travel longitudinally against the diaphragm as such engagements take In this manner I am enabled to provide a smooth diaphragm suitably actuated by a striker to cause the required emission of sound.
By this construction it will be seen that it is immaterial whether the motor is rotating in a forward or reverse maner as the operation will be the same with either direction of rotation.
A great advantage of my device will be apparent in ingly away from the diaphragm 1 which thereby permits the striker to get under way thus making before hitting the diaphragm, it very much easier for the motor to start in operation.
In Fig. 4 I show in detail how the striker is mounted. This striker 10 is provided with an annular groove 20 into which groove a preferably horseshoe-shaped retainer 21 is slid, whose extremities are then bent over as at 22, to prevent displacement. A collar 23 on the lug 13 on the opposite side of the arm 11 cooperates to hold the parts in place,
said striker 10, lug 13 and collar 23 being all preferably of one piece.
It will of course be understood that many modifications may be made from the structhat I mount the striker yield- .ture herein set forth without departing iron},
striker projecting through said-support, a
collar on said striker resting against one face of said support, a slot in .said striker adjoining the other 'face of said support, and a retaining device cooperating with said sllot and support to hold said striker in p ace.
2. In a device of the character described the combination with a su port, a striker arm projecting'through sai support, a collar on said striker resting against one face of said support, a slot in said striker adjoining the other face of said support, and
a retaining device cooperating with said slot' and support to hold said striker in place.
In witness whereof I hereunto subscribe my name this 14th day of September A. 1).,
PETER C. BURNS.
