ELECTRICAL SIG-N ALING VICE.

Ltlflll'ft., Specification o Application filed March i6, 1911.

.To all 'whom t may concern.:

lle it known that l, Trinononn ll'vuiss, a citizen of the llcl'nited States, and resident of Chicago, county of Cook, and State of illinois, have invented certain new and useful Improvements in Electrical Signalingl Bormes, of which the following is a specie tication, and which are illustrated in the accompanying drawings, forming a partthereof.

The invention relates to devices for giving Warning signal, and is primarily intended for the use of automobile drivers.

'.lhe object of the invention is toprovide a simple but powerful Warning signal; and it consists of an electric `n'1otor,`associated with a diaphragm, with special means, as hereinafter described. for actuating a tapper for rapidly striking the diaphragm to produce the desired sound,

The invention is illustrated in theaccom panying drawings, in which-` Figure 1 is a side elevation of the con1- plete device; Fig. 2 is a detail section through the easing carrying the diaphragm and showing the tapping mechanism; Fig. -3 is a detail in perspective of the tapping parts being broken away; and Fig. a is a sectional View on the line /l`4 of Fig. 2.

A rotary electric motor 10, of any suit able construction, is carried by a bracketarm 11,- adapted for attachment to an appurtenance, such as the dashboard of an automcbile, or other suitable support- A. chambered casing 12 is secured to the body of the the motor 10 by means of a collar 13,

'to which the casingl is suitably attached, as

by means of

arms

14, 15. A diaphragm 16, preferably of metal, is secured Within the casing 12, in a position perpendicular to the shaft 1l' of the motor, the center of the diaphragm being preferably in line with the axis of the shaft. A tapper or hammer 18 is sleeved upon the outer end of the shaft 17, and is free to move longitudinally thereupon. The tapper normally lies out of contact with the diaphragm, but is suiiiciently se thereto so that it may be thrown forci-y J against its face. A pair of rigid arms extend backwardly from the tapper 1S, and are inclined outwardly, and at their inner ends are provided with eyes loosely encircling a pair. of

arms

21, 22, pivoted to and projecting radially from collar @El fixed upon the shaft 17. A plier Patented June 11 Mll?. Serial No. 614,543.

f Letters Patent.

cams 2l, which are preferably V-shaped, are secured to the inner wall 2G of the casing l2 and projectninto the path of the arms 2l, 22 forcing them forward and thus revolution of the motor shaft. bviously by introducing additional cams, preferably in pairs, the tapping action becomes more rapid.

The diaphragm 16 is held against a shoulder at the forward end of the casing 12, by

casing. Preferably

soft gaskets

29, 30, which may be of cardboard or similar material, are applied to the opposite faces of the diaphragm, and there may be interposed between the inner gasket 29 and the shoulder of the casing a ring 27 and an annulus 33,-the latter having an instanding or radial ing a cup Within which the ring is inclosed. The cap 28 has a central aperture which formsthe throat of a resonating horn 3l. A collar 32 is fixed upon the shaft 17, and projects through and turns in a central apen ture in the rear Wall 26 of the casing 1,2.

`While` the motor-is shown arranged with its shaft perpendicular to the diaphragm, and this construction is preferred because of its simplicity, ll' do not desire to be limited to this arrangement. but regard my invention suiiiciently broad to include any arrangement of motor 'which will secure the rotation of the tapper-advancing mecha nism shown. indeed, the scope of the invention is suiiicient to include -any other form of mot-or than electrical, it being necessary only that the shaft carrying the advancing arms be given rapid rotation.

The cams 2li, are preferably V-shaped to permit the shaft to be rotated in either direction, so that a reversible motor may be employed. l claim r (1 Zr means of a cap 28 engaging the e'nd of the throwing the tapper 18 against the dia-4 and a peripheralflange,thereby constitutdiaphragm, a rotatable hea-d, arms project- ;ing radially fromthel head and pivoted to swing in a plane' coincident with theaxis thereof, barsconnectingthe'arms with the tapper, vand means for swinging the arms on 'their pivots. .c

2. In a signaling device, vin combination, a diaphragm, a tapper located ladjacent `the diaphragm, a rotatable head, arms projecting radially from the head and pivoted to swing in a plane coincident with the axis thereof, bars connecting 'the arms with the tapper means forswinging the arms on their pivots, andan-electric motor" for rotating the head.- i

3. In a signaling device, in combination,

i a chambered casing having an apertured end, a diaphragm secured Within the casing,

y ashaft journald in the opposite end of the casingfa' tapper slidably mounted on the end of the shaft'and adapted to strike the .diaphragm as it reciprocates, a head fixed to theshaft, arms radiating 'from' the head and ivoted theret-o to swing in a.

vplane coincident with the axis of the shaft,

bars connectingthe arms with the tapper,I and 'cams fixed to the casing and entering the path of ro ation of the arms;

4. In a si ling device, in combination` achambered 'casing having an apertured end, a diaphragm secured Within the casing, a shaft ournaled in the opposite end of the casing, a tapper slidably mounted on the -end of the shaftvandadapted to strike the ed Within the casing and being perpendicularto the axis of the shaft, a tapper slidably mounted on 'the end of the shaft and adapted to strike the diaphragm, a pair of. arms radiating'from the shaft and pivoted' to swing in a plane coincident with the axis thereof, connection between the arms and ythe tapper, andl cams fixed Within the casing and projecting into the path of rotation of the arms.

6. In'- a signaling device, -in combination, a rotary electric motor, a casing secured to the mot-or', the end ofthe motor 'shaft projecting into the casing, a diaphragm mount-- ed Within the casing andbeing perpendicw' lar to the axis of the shaft. a tapper slidably mounted on the end of the shaft and.

adapted to strike the diaphragm, a pair of arms radiating from the shaft and pivoted to swing in a plane coincidentwith the axis thereof, connection between the arms and the tapper, and V-shaped cams fixed within the casing and projecting-into the path of rotation of. the arms. l

Y"l". In a signaling device, in combination,

a diaphragm, an aria mounted to rotate`v about an axis perpendicular to the diaphragm and to swing toward and away from the diaphragm, a tapper for striking the diaphragm actuated vby the arm, and a' cam projecting into the path' of rotation of the arm.

8. In a signaling device, in combination,

.a diaphragm, a tapper locatedadjacent the diaphragm and impinging directly thereon, a head rotatable about an axis perpendicular to .the diaphragm, an arm' projecting radially from the head and being oscillatable in a plane coincident with the axis thereof and acting upon the tapper to force it against the diaphragm. and means for causing the movement of the arm.
