Application filed August 24, 1911, Serial No. 645,863. Renewed January 31, 1916. serial No. 75,468.
To all whom it may concern: 1
Be itknown that I, EMANUEL AU'FIERO, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Signaling Apparatus, of which the following is a complete specification.
My invention relates to diaphragm actuated alarms, such as are used on automobiles, motorboats and the like; and has for its object the construction of an improved device of this class.
In Figure 1, is shown a partly sectional view of a signal embodying my invention; Fig. 2, shows adjusting means for the displacing member; Fig. 3, shows a preferred way of fastening rotary member and impact piece' I have found that very desirable results are attained when the operating members are so constructed, that the diaphragm is apt to vibrate as a whole without formation therein of ripples or other secondary vibrations: I have found very efficient the use of a disk 17 (Fig. 1) provided with cam projections and fastened to the diaphragm 4; a similar disk 16 mounted on the armawhen ad tureshaft 12 of the electric motor 10 is used to simultaneously engage the projections of the first named disk and to vibrate the diaphragm. This construction permits compactness of design and eliminates the displeasing rattling of' similar devices where a single point of contact is used in vibrating the diaphragm, orwhere a number of contacting points contact successively, not simultaneously with a number of projections carried by the diaphragm. I preferably use cam projections having gradually increasing pitch in one way on one disk, and cam projections of increasing pitch in the opposite way in the other disk. The impact piece 17 may be secured to the diaphragm by means of screw 19 and nut 18, or any other suitable means. The front casing 2 may carry the resonator 20, or'may have a plain opening for the escape of sound; and the diaphragm may be clamped between cushioning wash ers 3. For sound-adjustments I preferably mount the armature shaft 12 so that it can be moved perpendicularly to its plane of rotation. composed of a screw 14 carried by frame 13, and a nut 15 maybe used to lock said screw 'usted-by advancing said screw 14 back an forth the amount of engagement combination A thrust bearing may be usedof the rotary member 16 with the impact piece 17 may be easily regulated. The motor carrylng arm 6 extending from the main frame 5, has an oblong hole 8 apt to receive screw 7 holding the motor 10. A nut 9, or any other suitable means may be used to lock said screw 7 when the motor has been adjusted to the exact distance from the diaphragm by means of said oblong hole permitting to and fro adjustments of the motor.
In Fig. 2 another preferable mode of adjustment is disclosed which permits the armature to remain in the same lines of force of the field magnets, while an adjustable member 25 provided with a threaded part 26 runs through said armature shaft 24:, which rests between the stationary bearings 22 and 23 carried by the frame 21. The displacing member 16, as seen, is mounted di rectly on said adjustable member 25, and a am-nut 27 may be used to hold said adjustof mounting the operatingthe male screw 30. It is easily understood that the threads are so disposed that rotation of disk 32 in engagement with disk 31 serves to tightenthe engagement with each screw.
I find very desirable the use of a cork washer 35, or any other cushioning material between the impact piece and the diaphragm, as it prevents an unclear sound produced by the slight unevenness of the contacting surfaces of the disks 31 and 32.
Various modifications, transpositions and changes may be resorted to without departing from the scope of my claims.
What I claim is 1. A signaling-device, comprising the of an acoustic plate, a rotary electric motor having a hollow armatureshaft disposed at an angle to said plate, a longitudinally-adjustable member located in said shaftand'having one end protruding therefrom, means for locking said member in the desired adjustment, and a plate-actuating device carried by said protruding end and actuating said plate.
2. In a horn or signaling device, a diaphragm, actuating means for-mechanically agitating the diaphragm, including a motor having a hollow armature shaft, and an adjustable diaphragm-displacing member provided with a stem extending into the bore of said shaft and adjustably secured fastthereto, whereby relative adjustment of the diaphragm and diaphragm displacing member may be effected.
3. The combination of an acoustic diaphragm, an electric rotary motor, a hollow armature shaft for said motor, a member extending through said shaft and adjustably secured fast thereto, and diaphragm displacing means mounted on said member.
4. The combination, in a signaling-device, of a diaphragm, and mechanical vibrating means therefor comprising the combination of a hollow rotary driving-shaft mounted in suitable bearings, a longitudinally-adjustable shaft located longitudinally within said hollow shaft, means for securing it at desired adjustment therein, and displacingmeans carried by said shaft to act upon said diaphragm.
