To all whom it may concern:

Be it known that I, Wnnnnmn .P. Suns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful 1m provement in Circuit-Controlling Devices, of which the following is a specification.

My invention relates particularly to cirsuit-controlling devices adapted for usein connection with motor-vehicles, and useful to control the electric circuits of electric horns, bells, or the like.

The primary object of my invention is to provide a device of the character indicated in which the circuit-controlling means is so disposed with relation to the steering wheel of the vehicle as to enable the operator to sound the signal or horn without the necessity of removing his hands from the steering-wheel, and without the necessity of removing his feet from the brake and clutch pedals of the machine.

'The invention is illustrated in its preferred embodiment in the acompanying drawin gs, in which- Figure 1 represents a plan view of the steering-wheel of an automobile equipped with my improved oircuit controlling device; Fig. 2, a plan view of the annular contact-member employed, and its supporting spider; Fig. 3, a broken elevational view of the steering-wheel and shaft equipped with the improved device, the view being partly in section and illustrating also the electric horn and its circuit. the latter being shown diagrammatically; Fig. 4, a broken sectional view of a steering-wheel equipped with the device in modified form; Fig. 5, a broken sectional. view showing another modification, the view-being taken as indicated atline 5 of Fig. 6; Fig. 6, a broken sectional view taken as indicated at line 6 of Fig. 5; and

Fig. 7, a-broken sectional view showing a modification of the steering-wheel shaft.

Referring to the preferred construction shown in Figs. 1 to 3 inclusive, A represents the steering-wheel of an automobile mounted on a shaft A; B. an electric horn equipped with a vibrator B and C, an electric circuit includinga battery C In practice, the horn B is suitably mounted on any desired portion of the machine. On gasolene machines. the horn is commonly mounted under the engine hood in the vicinity of the lower end of the steeringshaft. For convenience a diagrammatic Specification of Letters Patent.

is, connected with a metal portion-of the frame of the machine, so that the shaft A forms a portion of the circuit. Upon the shaft is insulatingly mounted a collar 2, which carries resilient arms 3, upon which is mounted an annular contact-member 4. The other conductor 5 of the circuit C is connected to the collar 2. The annular contact-member4 is disposed beneath the metallic arms 6 of the steerin :Wheel, and in close relation thereto;' an said annular member is or" somewhat smaller diameter than thesteering-wheel, so that when it is a desired, the operator may, without releasing his hold on the steering-wheel, employ his fingers to press the member 4r'upward y into contact with a. rib, or ribs, of the steeringwheel, thereby closing the circuit C.

The collar 2 may consist of a two-part clamping-ring, as shownzin Fig. 2. The clamping-ring is insulated by the bushing 7, which is of insulating material. clamping-ring, together with the spring arms 3, afiords a spider which supports the ring n Thering 4 may comprise a rod bent into annular form and having its'ends joined together byfa union 8. The ring 4 lies in a plane parallel with the plane of the wheel A and immediately beneath the plane of the metal arms 6 of said wheel. The annular space9between the ring 4 and the rim 10 of the wheel is preferably of such width that manipulation of the steering-wheel, but the space 9 is nevertheless small enough to enable the operator to readily extend his fin gers beneath the steering-wheel to press the member 4: upwardly to close the circuit. The conductor 5 extends downwardly along the shaft A, is suitably insulated, and may, if desired, be ineased in a flexible metal armor. It is to be understood that the con- .ductor 1 is shown connected with the shaft A merely for convenience of illustration.

in the modification shown in Fig. 4, A represents a portion of a steering-wheel, and
