ELECTRIC HOT-WATER FAUCET AND MEANS FOR OPERATING SAME.

Application filed May 10,

My invention relates to electrical hot water faucets and to the means and method of operating and controlling same. It has for its purpose to furnish an economical and efficient heating unit for water faucets, to provide a dual operating switch combination comprising a primary switch adjacent to the faucet adaptable to operate a secondary magnetic switch distant from the water cet; to minimize the possibility of electrical shock to the operator; to provide indicating means designed to function in event the contact breaking means fails through breakage or other cause; to provide a novel primary switch mechanism adaptable for operation by a faucet handle; to render electrical water heating faucets available for commercial and home use under rigid safety requirements; and to provide the various other advantages and results made evident from the following specification. I accomplish th objects of my invention shown in the accompanying drawings which form a part of this specification and in which Figure 1 is a front view of a hot water faucet to which my device has been adapted, with a commercial type magnetic switch connected below. Figure 2 is a sectional view on the line arr-a, in Figure 1. Figure 3 shows the working parts of the primary switch, the faucet handle being in the position of on, and the switch contact closed. Figure shows the primary switch mechanism with the contact broken, the faucet handle being in the position of off.

Refering again to Figure 1, B shows the faucet handle. C shows the water spout or outlet, D and E show holding screws by which the switch cover F is held in position. G shows a loose plate which slides as the handle B is moved, and through which passes the handle finger B (see Fig. 2) extending beneath the cover F. H shows the case in which is contained the heating unit, I shows the magnetic switch connected by the wires K and L to the heating units J (see Fig. 2) in the holding case H. M and N show the wires connecting the magneticswitch I with the source of electrical energy.

Referring again to Figure 2, O shows the fixed conductor of the primary switch. P show the wire connecting same with the magnetic switch I. 0 shows the water pipe connected with the source of supply. it shows insulation sections between the case H and the coils S. R show openings in 1926. Serial No. 107,925.

the insulation discs through which openings the water from the source of supply passes onto the coils S and out through the spout C. B shows the pivot on which the faucet handle turns.

Referring again to Figures 3 and 4:, T shows the movin arm of the primary switch the lower part of which T is of any suitable metal adaptable for use as a conductor. The upper half T is of any suitable non conducting material. T show the rivets with which the two parts are joined. The upper part of the moving arm is slotted at U to engage the finger end B of the faucet handle B. The arm T is hinged at T and as the faucet handle B is turned to its on position the circuit is completed by contact at O and T With the handle B in its off position the contact at O and T is broken. Turning the handle B in the direction away from its on position delivers cold water, the electrical contact being then broken. 7 shows a pin mounted in the spring to exert a pressure against the arm T, designed to indicate when flush with the cover F that the electrical contact is perfected, and when extending beyond the surface of said cover to indicate that said contact is broken. P and P show the wires connecting the primary switch withthe magnetic switch. V and V shows the conductors leading from the heating units J connected with the magnetic switch I by the wires K and L.

In operation, assuming that the handle B is in its neutral position and that the operator wishes to draw cold water; the handle is moved away from its on position so that the arm T does not complete the circuit to the magnetic switch unit and the heating coils S. V] hen it is desired to draw hot water the handle B is turned to its on position, as shown in Figure 3, at which time the arm T is moved to close the circuit through conduct-ing portion T of arm T engaging contact O. The circuit is thus completed through wires P-P from the primary switch to the magnetic switch hence throwing the magnetic switch to close the circuit through wires KL to the heating coils S. Since the water flows around the heating coils it is brought to the proper temperature before being discharged from the nozzle of the faucet designated by C; and since there are two electric circuits, one controlled by the other, shocks are prevented through the handle B, and the device fully fulfills the plumbing requirements of local municipal building regulations.

S1m1lar letters of reference refer to similar 1 parts throughout the various views.

I do not desire to confine myself to the specific details of construction herein set forth but claim all such variations and equivalents as may well be construed to fall within the scope of the appended claims.

Having thus described my invention 1 claim as new and, desire to secure by Letters Patent of the United Statesof America:

1. In a device of the type described, a taucethaving a handle for controlling the outlet ot'fluid therefrom, a heating coil interposed in the path of fluid passing through the faucet, a switching device operable from the handle and connected with a source of power and with the heating coil and comprising a pivoted arm formed with an upper andalower section; the upper section being formed of non-conductive material, and the lower section being formed ot conductive material and connected to the upper section, acontact for completing the circuit when the pivoted arm is moved'to engage its lower portion thereon, and the upper portion of the arm being operatively connected with the handle.

2. In a device of the type described, a faucet having a handle "for controlling the outlet of fluid therefrom, a heating coil interposed in the path of fluid passing through the faucet, a switching device operable from the handle and connected with a source of power and with the heating coil and com therein, and means engaging in the slot and connected with the handle for throwing the switch upon movement of the handle.

3. In a device of the type described, a faucet having a handle for controlling the outlet of-fluid therefrom, a heating coil interposed in the path of fluid passing through the faucet, a magnetic switching device in circuit with the heating coil, and a control switch in circuit with the magnetic switch for throwing the same to power the heating coil, said control switch operable from the handle and connected with a source of power, and comprising a pivoted arm formed with an upper and a lower section, the upper section being formed of non conduct-ive material, and the lower section being formed of conductive material and connected with the upper section, a contact for completing the circuit when the pivoted arm is moved to engage the lower portion thereon thereby to throw said magnetic switch, the upper por-' tion or" the arm having an elongated slot therein, and means engaging the slot and connected with the handle for throwing the switch upon movement of the handle. 7
