SIGNALING DEVICE.

Specification of Letters Patent.

Application filed January 19, 1910. Serial No. 538,815.

To all whom it may concern:

Be it known that I, HENRY BERGONZINI, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Signaling Devices,

' of which the following is a full, clear, and

Another object thereof is to provide j device of this character which may be easily attached toany suit-able frame, readily ad; ,justed in position and in which the electric connections may be quickly and positively made.

Other. objects will bein' part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features ,of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter setforth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein 15 shown one of various possible embodiments of thisinvention,Figure 1 is a diagrammatic side view of an automobile showing the signaling device attached thereto; Fig; 2 is a side elevation partly in section, of the signaling lxdevice, the section being taken on line wa;i of Fig. 3. Fig. 3 is a front view of the diaphragm casing with the cover and diaphragm removed; Fig. 4 is a planview of the motor casing showing the means employed to vibrate the diaphragm, parts. being in section 5 Fig. 5 is a perspective view of a crank dlsk and cam'adapted to drive the vibrator; Fig.' 6 is'a detail view partly in section of the-vibrator and associated parts: Fig. Tie a sectional view of a socket adapted to complete the elect-ric "circuit through'the motor; Figs. 8 and 9 are interior views of.

thetwo halvesof the :socket; Fig. 10 is an Motor pole pieces 25 may be formed as part end view of the parts shown inFig. 6.

- said bracket.

Similar reference numerals refer to simia lar parts throughout the several views. Now referring to the drawings, 1 indicates a casing adapted to inclose the motor and secured to this casing is a second casing 1 adapted to contain the means used to pro duce vibration of the diaphragm 2. While in the present form, the casings l and l" are integral with one another, it is obvious that they may be made separate and secured together in any manner desired, without departing from the spirit of this invention The casing 1 is provided with a tubular arm 3 whichterminates in a socket member 4.

Upon a reduced portion of the arm 3 a bracket 5 is adapted to swivel and to be Patented Apr. 2a, 1913.

tightened thereon by means of a thumbscrew 6. In Fig. l the casing is shown as secured to the frame of an automobile by means of The leadsfrom the motor are fastened to contact members 7 in the socket member 4, these contact members being supportion thereof, thesocket member 4 of thecasing. The two membersare s cured to: gether by means of a bayonet jointf'c'o'mpris- ,ing a pin 1.4 and an angular slojtfl15. The

wires 16 from-the battery are secured to two contact members 17 disposed within and in; sulated from the socket member 13 in such manner that when the socket members are locked together the contact'mernb'rs of" the one part will engage the contact members of the other part and complete the electric circuit to the motor. v

The casing 1 is provided" adjacent one end of the motor armature 18 Ywith acap l9 providing an end bearing f'onthearmature shaft .20; The other end. oaths" armature shaft has ita bearing in the wall'21 of the casing 1, through which it extendspto have secured thereto a crank disk 22* provided with a crankpin. 23, and carrying upon its outer surface; a cam .member'Q i, the object of which 'will be hereinafter described.

of easing 1 and the field coils 26 placed thereon in the usual manner. The brush holders 27 are supported'by a fiber insulat ing' ring 28 a and the brushes are forced against the commutator in any 'suitable manner. The casing 1 extends beyond the walls of the motor casing 1 and provides an annular flange 29 threaded'upon its outer circumference and surrounding a space 30 within which the crank disk 22 rotates. A cap 31 is provided with a flange 32 interiorly threaded to engage with the threads on flange 29, which upon being screwed thereon serves to clamp therebetween theresilient diaphragm 2. Located in the center of the said diaphragm and secured to the inner side thereof, is a projecting member '33 providing two abutments 34 and 35. A horn or resonator 36 of any desired construction fits securely over a forward projection 37 of the cap 31; Extending in-- wardly from the inner circumference of the;

flange 29, are two lugs 38 which are formed to serve as one side of a guide, of which the other side comprises two similar members 39, secured to the casing 1 by means of screws 40. Between these guides a sliding member 41 is adapted to reciprocate, the

motion thereof being in a plane substg;

tially parallel to the plane of the diaphra 2. At about the center of the saidslide extends a transverse member'42 which is provided with a slot 42 as shown in F ig. 3, adapted to receive the crank pin'23. Upon opposite sides of the slide, adjacent the two ends thereof, slots 43 and 44 are provided. Toothed members 45 and 46 are pivoted to the slide within these slots, the said members extending longitudinally of the slide upon either side thereof in opposite directions.

an opposite direction to the teeth of the member 46', and that the teeth of each member slope away from the pivotal point thereof. Spring members 47 secured at the two ends of the slide press upon the top of of this invention, the operationthereof,

which is largely obvious, follows: Upon the electric circuit being closed at the push-but- It will be seen by reference to Fig. 6 that the teeth of the member 45 are disposed in ton, the motor armature begins to rotate, the crank disk 22 rotating therewith. This rotation is transmitted by the crank pin to the slide member 41 as a reciprocating motion within the guides. As the slide moves toward the left, as viewed in Figs. 3 and 6,

the toothed member 45 is raised by the cam 24 so that the points of the teeth thereon come into contact with the abutment 35 upon the diaphragm. The contact of each tooth with the abutment produces vibration of the diaphragm, and upon, reversal of the movement of the slide,'the cam moves from beneath the toothed member=45 and into contact with the toothed member 46, permitting the former to drop and raising the latter into contact with the diaphragm abutment 34, whereupon the diaphragm is vibrated by the latter member and as the teeth of one member are spacedrelatively to the teeth of the other member so as to produce the effect of a continuous, uniformly toothed surface, the vibration of thediaphragm is continuous and uniform. While any motor speed or number of teeth may be employed, the best results'have been obtained by using a series motor adapted to runat about 3,500 revolutions per minute when taking current from a source, having a difference of potential of-v about eight volts. Ten teeth are PIOXldGd, giving the number of diaphragm impulses as 35,000 per. minute. At this rate of vibration the diaphragm gives forth tones adapted to effectively alarm those for whom the warn ing is intended. Thediaphragm may be spaced nearer to or farther away from the toothed members by inserting suitable washers between the same and the casing. It .Will accordingly be seen that herein is provided an apparatus well adapted to attain, among others, all the objects and ends above pointed out in an exceedingly simple yet efiicient manner. The motor, reciprocatingmechanism and electric wiring, all being inclosed are well protected from the effects of bad weather conditions and because of the form of the vibrating mechanism a very compact construction is made possible of attainment. It should be noted that when the current is shut off, the motor will. stop approximately upon the nearestdead-center of the reciprocating device, thus, almost immediately stopping the sounding of the alarm.

As many changes could be made in the;

above construction and many; apparently widely-different embodiments of this invention could be made without'departing from... the scope thereof, it, is intended that all matter contained in the above description or shownin the accompanying drawings shall be interpreted asillustrartive and not 'in a limiting sense. It is also to'be. understood that the language used in the follow. ing claims is intended to cover all of the combination, a horn or-resonator, a diageneric and specific features of the invention herein described and; all statements of: the scope of the invention, which, as a matter of language, might be said to fallthere between. 1
