A TTORNEY UNITED STATES GEORGE J' SEISS,

OF TOLEDO, OHIO.

MECHANICALLY-OPERATED HORN.

Specification of Letters Patent. Patented J an 27, 1920.

Application filed March 11, 1918. Serial No. 221,602.

To all whom it may concern:

Be it known that I, GEORGE J. Sines, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Improvement in Mechanically-Operated Horns, of which the following is a specification.

My invention relates more particularly to that part of the device which actuates the mechanism for vibrating the diaphragm, and has for its object to greatly simplify the construction and to increase its strength. Horns of this type are subject to very much greater abuse than are the horns of the electrically driven type, and very frequently are so placed as to be operated by the foot, and are kicked violently so that they become bent, and onsequently inoperative.

My invention has for its object to provide a construction for the actuator which will be very inexpensive to manufacture, and which will be much more capable of resisting unusual strains than the construction at pres ent employed.

My means of accomplishing the foregoing object ma be more readily-understood by having re erence to the accompanying drawings, which are hereunto annexed, and are a part of this specification, in which;

Figure 1 is a vertical, sectional view of a horn fitted with my improvements;

Fig. 2 is a vertical. sectional view of the actuator;

Fig. 3 is a detail view and cross section of same.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the horn is provided with a cylindrical body, 1, in which is mounted a diaphragm 2, which is provided with a lug 3, adapted to be engaged by serrations, formed upon a disk 5, mounted upon a shaft 6, suitably rotatably mounted in the body 1. A pinion 9 is mounted upon the shaft 6, suitably journaled in bearings which may be mounted in the sides of the body 1, and provided with suitable clutch mechanism for rotating the disk 5 in the desired direction. The actuator 10 is mounted in a guide 11, which is suitably secured to the body 1 of the horn, so that the teeth 12, formed upon the actuator 10 are adapted to mesh with the teeth of the pinion 9. A

button 13 is suitably secured to the upper end of the actuator 10, to permit its manual or pedal operation.

Ordinarily, these actuators are made of solid bar steel, the teeth 12 being milled. In my improved construction they are stamped or formed in a channel which is U-shaped in cross section, as clearly seen in Fig. 3, the teeth 12 being stamped instead of being milled. A lug 13 is provided at the lower end of the actuator and slides in a channel formed in the guide 11, so as to prevent the withdrawal of the actuator accidentally or otherwise after the horn is assembled. A tongue 14 is punched out of the rear wall of the actuator 10, serving as a brace to the walls thereof, and is provided with a perforation in which is mounted a rod15 which is surrounded by a coil spring 16 which operates to return the actuator to its normal position after it has, been depressed.

Practice has shown that an actuator constructed as described, not only is very much less expensive to manufacture, but is a very considerable improvement over the solid ones, owing to the fact that it does not get bent or distorted, and therefore greatly increases the usefulness of the horn.

Having described my invention, what I regard as new, and desire to secure by Letters Patent of the United States, is:

1. A horn body, a guide extending through the body transversely, said guide having a slot in one wall, an actuator slidable in the 7 guide and comprising a stamping of metal U-shaped in cross section having teeth on its edges and a projection slidable in the slot of the guide, a diaphragm, and means for communicating the motion of the actuator to the diaphragm.

2. A horn body, a guide extending through the body transversely, said guide having a slot in one wall, an actuator slidable in the guide and comprising a stamping of metal U-shaped in cross section having teeth on its edges and a projection slidable in the slot of the guide, a diaphragm, a spring in the guide bearing against the actuator, and a hand engaged member carried by the actuator.

In testimony whereof, I have signed the foregoing specification.
