Application filed July 18, 1912. Serial No. 710,206.
1 whom it may concern tie it. known that I, SAMUEL AUSIIN, a r'tizen of. the United States, residing at t'lford, in the ci'iunlzy of lslartfo'rd and and useful Improvement in SignziLHorns,
of which the following is a specification.
This invention relates to a signal or alarm horn for aatouwbiles and motor boats, of the head.
The object of this invention is to provide a very simple and cheap horn of this nature, which. can be readily applied to any of the various types of automobiles and motor boats in common use, in such position that when. it is desired to-sound a signal or give a warning alarm, the horn can be instantly brought into operative connection with the engine tly wheel or similar rotating part that is turned by the engine, and caused to throw out. a loud, pleasing and carrying sound. This object attained by mounting a drum with a metallic head on a rotatory shaft that can be driven from an engine fly wheel or similar part, the drum head having projections that when the drum is rotated, intermittently engage with fixed projections in such manner as to cause the head to be violently vibrated and throw out the desired sound waves through the amplifying bell or horn.
Figure 1 Off the accompanying drawings shows a horn which embodies this invention, with the casing and drum-cut in central iongitudimil section. Fig. 2 shows a trans verse section on the plane indicated by the dottedline on Fig. 1, looking in the direction indicated bythe arrows .2. Fig. 3 shows a similar section on the same plane, looking in the direction indicated by the arrows 3.
The casing 1 ot the horn may be cast to shape of iron, brass, or any other suitable metal. This casing is circular and is open at the front. Projecting from the back of the casing is a hollow hub 9.. Extcndin from the huh there may be a bracket 3, by means of which the device can be pivotally connected toany convenient part of the vehicle adjacent to the engine 'or'motor by which it is, ;to--be operated. Screwed into the threaded end of the. hub is a'sleeve 4, and rotating in this hub is a spindle 5. The
form of device shown has anti-friction bear ings (3 interposed between the ends of the sleeve and the spindle cones to provide for the tree rotation of the spindle. The outer pone 7 is preferal'il y movable on the spindle in order that the bearings may be properly adjusted, and the sleeve may be turned more or less in or out of the hub for correctly locating the spindle. The inner bearing cone 8 is formed at the center of the back of the drum 1). Secured across the front of the drum is a. metallic plate 10, whichdesirably has secured to its front face four hard steel balls 11,.
l astened. over the :lront of the casing is a cover plate 1;. This plate has a central opening l3 and numerous perforations 1-l. Secured to the inner side of this plate, adjacent to the central. opening, are two hard steel balls 15. llu-se balls on the inner face of the cover pla i are located in the path of the balls on the front face of the drum head so that 'Wilvll the drum rotated, the balls will intermittently cngageand violently vibrate the drum head. The sound amplifying hell or horn 16 is secured to the front of the cover plate.
()n the outer end oi" the spindle is a pulley l7. This pulley may be provided on its periphery with a friction facing or band 18 of leather or any other suitable material which will increase its traction on the sur-' face of the part which is utilized to drive it and rotate the spindle. The device is mounted on a vehicle so that the rim of the pulley will be adjacent to the surface of the engine fly wheel 8 or similar rotating part. The device may be moved for bringing the periphery of the pulley into contact with the periphery of the. fly wheel by any suitable mechanism. A rod 11) and pedal 20 are shown as illustratingone manner of accomplishing this, and a spriiig 21 is illustrated in such position to lift the pedal and move the-device so as to carry the periphery of the pulle away from the periphery of the fly whee The spindle bearing is adjusted by turning the outer cone, and the bearing sleeve is turned in the hub for adjusting the drum so that the balls carried by the head will make the proper contact with the fixed balls is brought into frictional enga ement a is'rotated by the fly wheel, t 'e drum is driven at a high speed, and as the balls "carried by the cover plate. then the pulle is vibrated in such manner as to throw out a loud, yet pleasing sound. This sound has la -ge volume and is toned by the drum formation of the'rotating part, a11d also by the openings through the cover plate from the drum chamber in the casing to the interior of the sound amplifying horn.
The invention claimed is: r
1. A signal horn having a casing, a spindle supported by the casing, a drum located in the casing and rotated by the spindle, said drum having a resilient metallic, head with outwardly extending impact projections, and a plate attached to the casing, said plate having projections in the path of the impact projections on the drum head.
'2. A signal horn having a casing, aspindle supported by the casing, a drum located in the casing and rotated by the spindle, said drum having a resilient metallic head with outwardly extending impact projec-- tions, a plate attached to the-casing, said plate having projections in the path of the impact projections on the drum head, and a horn secured to and projecting from the cover plate.
23. A signal horn having a casing, a sleeve adjustably supported by the casing, aspindle extending through said sleeve, a drum l cated in the casing and attached to the spindle, said drum having a resilient metallic head with outwardly extending impact projections, and a plate attached to the casing, said plate having projections in the path of the impact projections on the drum head.
' 4. A signal horn having a casing, a sleeve adjustably supported by said casing, a spindle extending through said sleeve, adjustable 40 bearings between the spindle and sleeve, a drum located in the casing. and attached to the spindle, said drum having a resilient metallic head with outwardly extending impact projections, and a plate attached to the casing, said plate having projections in the path of the impact projectionson the drum head.
5. A signal horn having a casing, a drum with a resilient metallic head provided with impact projections located within the vasing, means for rotating said drum, and fixed projections extending into the path of the impact projections carried by the drum head.
