AUTOMOBILE-HORN.

To all whom it may concern-.-

Be it known that I, RAY H. MANSON, a

trolled by an electric current, the particular object of my invention being to improve the hcrnsnow being manufactured and placed upon the market.

' Another object of my invention is to produce a-shorthorn, such as is especially adapted for useupon motor cycles. To accomplish this, I have arranged the apparatus in the rear part of the horn in a compact structure, making it as-[iat as possible so as to shorten the horn.

Otherparticular objects of my invention will be better understood from the particular description which is tofollow. In this description I have described one embodiment of my invention, which is illustrated in the accompanying drawing.

This application is a successor of my application #695,386, filed May 6, 1912, which application but not the invention disclosed therein is abandoned, in view of the present application.

Figure 1 is a section through an automobile horn illustrating my invention, part of the resonator bein shown in elevation. Fi

2 is a rear end elevation of the partsshown in Fig. 1 with the rear cover removed.-

Figs. 3 and a are details.

Referring now to the drawing and to the embodiment of my invention illustrated therein, at 7 I have shown a main frame piece or supporting member, the main portion of which is flat, but the top portion of which is dished by stanming or other means, as shown at 6, the side '5 being shown inclined.- The bottom 8 of the dished portion contains an opening 9 which in the form shown is eccentric with respect to the bottom of the dished portion. A sonorous member,

preferably a vibratile diaphragm'is mounted upon the edge of the dished portion in any suitable way, the diaphragm being preferably concentric with the dished portion. In the form shown, the diaphragm is clamped between the front 11 of the frame and the frame piece 7, the three parts being connected togetherby some suitable means, such as screws 12.- An opening 13 is formed in the front 11 for the passage of sound waves, and a resonator 14 may be mounted in this opening. The lower part 15 of the main frame piece? constitutes a bracketfor connecting the horn to any suitable support. Of course, this bracket may be separate from the frame piece. I prefer to mount an anvil 16 upon the diaphragm in order that the vibrating member may strike thereagainst to cause the diaphragm to sound a signal. This serves to protect the diaphragm and to concentrate the blow upon the geometrical center thereof. Electromagnetic means including an armature 17 are employed. In the form shown I have illustrated an angle armature- As shown, the armature constitutes what is practically a right angle and may be cut from an ordinary piece of angle iron, thus greatly reducing the cost of manufacture and improving the efficiency of the device. This armature is connected to the frame, and in the form shown, I employ a resilient member, such as a flat spring 18, connected by some suitable means, such as a screw 19 to the armature. This may be connected to the limb 20 of the armature, which is preferably substantially parallel to the diaphragm.

The spring is connected to the limb 20 adja cent the bent part of the armature, and at the othenend the spring is connected to the main frame piece 7 by some suita-ble means, such as screws 21. In the form shown,- this connection is at the edge of the opening 9 in the bottom of the dished portion 3fthe main frame piece 7.

The limb 20 of the armature carries-the contact 22, preferably upon the back side thereof. The other limb 23 of the armature is adapted to be acted upon by electromagnetic means, such as electromagnets 1%. These magnets consist of coils 25 which are mounted upon a core composed of a plurality of punchings 26. In the form shown, these punchingsare U-shaped and have a winding upon. each limb thereof. The unchingsi are connected preferably to 'the bottom portion or back side of the frame through suitable means, such as a support 30 and screws 31, the support 30. serving to space the core from the frame. In the form shown, I have illustrated the magnets as being connected to the edge of the opening 9, oppositethe connection of the armatureiofsuch frame piece. At 401 show aflexible member, here illustrated as a spring which is connected at each end to the frame.

' Iprefer to connect this to the mainframe piece 7" upon the edge of the opening 9,

eing best mounted uponthebottom of the-- dished portion .Any suitable connecting means, such as screws 42' and supports or spacing members 43 are employed; 'This member carries a contact .45asshown in-.

termediate its ends, and in a position to e0 mediate member70 to one of the screws 42.

One end 71 of the member'70 is folded over and enters a perforation 72 in the frame 7. This locks the screws together in a well known Way, preventing the screws 42 from shifting their position.

It will be obvious to those skilledin the art that numerous and extensive departures from the formandthe details of the ap paratus here shown ay be made without departing fromthe spirit of the invention, the same being herein shown solely for the purpose of illustrating one specific embodr' ment of the invention.
