Specification of Letters Patent.

COMBINATION-HORN.

Patented Dec.15,:1914.

To all whom it may concern:

Be it known that I, JosnPH XVILLIAM JONES, a citizen of the United States of America, and a resident of New York city, New York, have invented a new and useful Improvement in Combination-Horns, which improvement is fully set forth in the following specification.

his invention is a combination horn for automobiles or the like.

The invention comprises combining into a single unit ofan electromagnetically-actuated diaphragm (operated by a push button or other switch) and a reed (actuated as by a bulb or the like), by means of which can be given either of two signals or tones besides a third signal or tone due to the simultaneous operation of the two devices.

The invention consists further in certain details of construction and arrangement to be hereinafter set forth and claimed.

My invention will be best 'understoodby reference. to the annexed drawings in which- Figure 1 is a side view of the combination horn; Fig. 2 is a sectional view of the electromagnetically-operated portion thereof: and Figs. 3 and 4 are details.

Referring to Fig. 1, the horn proper or trumpet 1 is of any desired- (flaring) shape, and at the rear extends inone or more coils to the tube 2, which is connected with the bulb or other device not shown) for sounding the reed (not shown). indicates the casing of the electromagnetically-operated diaphragm, which is connected to the trumpet 1 by the neck 4. 5 is a ring which forms part of the diaphragm-support, and extends as a plate 6, where it is provided with holes for securing the device to an automobile or the like.

Fig. 2 shows the construction of the interior of the casing 3. The ring 5 carries the forwardly-extending wall 7 which is reduced at 1 for uniting with the reartrumpet 1. 8 is a disk having a central aperture and" carrying a cylindrical wall 9, withanoutwardly-extending flange 10, and the offset flange 11. The offset flange 11 is located adjacent to the rear face of plate 5, to which it is secured by screws 12. Between flange 11 and plate 5 is clamped the metal diaphragm 13. there being preferably a countersink in the face of flange 11 in which the diaphragm fits. Secured to the center of the diaphragm as shown, by a rigid union is the rearwardly extending rod 14, that protrudes through the central aperture of disk 8,

into a position to be hammered upon by'the armature of the electro-magnet. The electromagnet is mounted at the rear of disk 8, and is inclosed by easing 3. Preferably I employ for the electro-magnet a unitary racket 15, which is best seen in- Fig. 3. This bracket consists of the base-plate or disk cut away at one side, at 16,.to a point past its center, and having integral therewith the yoked posts 17-17 that straddle space 16, and o posite thereto the single post 18. From t e top of the yoke extends transversely across the bracket a spring 19 that carries the armature-bar or hammer element 20; on top of the spring and above the yoke is the sleeve 21, and resting upon top of this sleeve and of post 18 is the bridge-piece 22, which is insulated from its sup orts but secured thereto by the screws 23-24, screw 23 securing sleeve 21 and spring 19. Instead of screws 23-24 taking into posts 17-18, the tops of these posts may be screw-threaded and nuts turned down on them. The tip of screw 25, in the brid e, coacts with spring 19 to make and brea the circuit. 26-26 are spring-clips secured at the rear of bridge 22, one of the clips being insulated therefrom, and the two arranged to engage the two terminals 27-27 of casing 3. them being shown) are secured in the usual manner to the face of the bracket 15, (as at the point 29 Fig. 3). When the spools have been secured and all parts properly assembled u on the bracket. the base thereof is secure to the plate 8 by screws 30, the parts being so arranged that the vibrations of the armature 20 will hammer properly upon the rear end of rod 14 to vibrate diaphragm 13. The casing 3 is domeshaped as shown, with an offset about midway and a flange at its forward end, to engage over the electro-magnet and over the central portion of bracket 8, so as to rest upon the outward flange 10, to which it is secured by screws, a rubber gasket 31 being interposed. The terminals 27 are carried by, but insulated from, the rear of the casing,

The spools 28 (only one of spring-clips 26.

the inner ends of the insulated terminals 27 engaging with-the clip-terminals 26.- The parts are readily assembled; and if, for any reason, it be desired to get at the interior, they are as readily taken apart-and put together again. The wires (no-t'shown) leading from the terminals 27 will be incircuit with a batter or other source of power, and the circuit Wlll be controlled by a push button or other convenient form of switch.

The rod 14 will preferably be adjustable withrespect to the armature 19: one way of accomplishing this is shown in Fig.4. The block 32 has a reduced screw-threaded. portion fitting a central aperture in diaphragm 13; a nut 33 is screwed down upon this rei '5 of fiber or the like,-

tendency to duced portion to clamp the whole upon the diaphragm; a screw 34 is longitudinally adjustable through the block 32; and the rod 1 4:extends rearwardly from this screw 34. By turning screw 34 in or out the rear end of rod 14 is brought into proper relation with armature-bar 20. Preferably the rod 14 and its parts are insulated from'the'di'aphragm 13. For this purpose, 35 is a sleeve, encircling the reduced portion of block 32, and having a flange interposed between the shoulder of the block and the adjacent face of the diaphragm; .and 36 is a ring of fiber on the opposite sideof the diaphragm. These insulating parts 35-36 prevent any passage of current to the diaphragm and thence to-the plate 6 and the automobile. V

The device as a whole occupies but little space and is located at any convenient place upon the vehicle. The bulb for thereed will be located as usual, and thepush button may be located upon the stem of the bulb or at any convenient point. The operator can sound the reedfor certain purposes and the diaphragm for others; and, when desired, he can sound them .both simultaneously and produce the blended effect. The reed feature, when usedalone, operates in the well-known manner which needs no further explanation. The actuation of the diaphragm is positive and W'ithindirect control of the operator. The blows or impacts upon the diaphragm are at a right an le thereto, and there is no strain or dislodge any of tlie parts., f Although I have given a detailed description of my invention, it will be understood that this is for the sake of.clearness, and that my invention is not limited to the precise detailsset forth; also partsof my, invention may be used to the exclusion of other parts, and modifications, transpositions, and

reversals may be resorted to, without in any case departing from the spirit of-the invention.
