SAMUEL W. NETHERTON, OF ROBERTS, ILLINOIS.
FLOAT-CONTROLLED SWITCH FOR FILLING TANKS.
To all whom it may concern:
Be it known that I, SAMUEL IV. NETHER- TON, a citizen of the United States, residing at Roberts, in the county of Ford and State of Illinois, have invented a new and useful Float-Controlled Switch for Filling Tanks, of which the following is a specification.
The invention relates to a float controlled switch for filling tanks.
The object of the present invention is to provide a simple, inexpensive and efficient device, designed for use on tanks into which water is pumped by means of a gasolene engine, and adapted when the water reaches a predetermined level to automatically stop the pumping by throwing the engine out of operation.
A further object of the invention is to rovide a device of this character, having a oat controlled switch, adapted to be automatically operated to open the sparker circuit of a gasolene engine for stopping the latter, when the tank is full.
With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings :Figure 1 is a diagrammatic view, the tank being partly in section,
showing a float controlled switch and illustrating the arrangement of the circuit for connecting the device with a gasolene engine. Fig. 2 is an enlarged plan view of the device. Fig. 3 is a longitudinal sectional view, taken substantially on the line 0:r of Fig. 2. Fig. 4c is a transverse sectional view, taken substantially on the line y of Fig. 2.
Like numerals of reference designate corresponding parts in all the figures of the drawings.
1 designates a switch arm, which is adapted to open and close a circuit 2, having terminals 3 and 4 connected, respectively, with the pivot 5 of the switch arm and a contact 6. The switch arm is connected with one end of Specification of Letters Patent.
Application filed August 9, 1907.
Patented March 23, 1909.
Serial No. 387,919.
a coiled spring 7, which is secured at its other end 8 to the board or support 9 upon which the switch is mounted, and the said coiled spring 7, which is distended when the switch is closed, is adapted to automatically actuate the said switch arm to open the circuit and stop a gasolene engine 10, when the said switch arm is released from engagement with a lever 11, as hereinafter fully explained.
The gasolene engine, which is designed to be operated for pumping water into a tank 12, is provided with an electric sparker of any well known construction, and is connected with the terminals 13 and 14 of the circuit, as indicated in l of the drawings. A battery 15, or other generator is placed in the circuit 2, and the wires thereof extend therefrom to the board or support 9 of the float controlled switch mechanism. When the switch arm 1 is in engagement with the contact 6, the circuit is closed and the engine, so far as the electrical connections are concerned, is in condition for operation, and when the switch arm is moved away from the contact 6 the circuit is opened, which stops the engine and the pump, as will be readily understood. The circuit is also provided at an intermediate point between the lioat controlled switch mechanism and the batteries with a supplemental switch 16 for enahling the sparker circuit to be closed, when it is desired to use the gasolene engine for other purposes than pumping water into the tank 12. The supplemental switch 16 is adapted to close the circuit, when the switch arm 1 of the float controlled mechanism is in the open position, illustrated in dotted lines in Fig. 2 of the drawings.
The support 9, which is located at the top of the tank, extends inwardly over the same and its inner portion is connected with the side of the tank by means of a brace 17, secured at one end to the lower face of the support and to the inner face of he adjacent side of the tank. The inner portion of the support is provided with a depending guide 18, consisting of vertical rod and receiving a float 19 having a central opening for the passage of the rod and guided by he latter. The lower end of the rod is provided with a head 20, forming a stop for limiting the downward movement of the iioat hut any other preferred form of sto may be employed. The upper end 21 of the rod 18 is threaded to engage the support, but it may be secured to the same in any other preferred manner.
When the water in the tank 12 rises above the lower end of the guide 18, the float will be caused to actuate a vertically movable rod or plunger 22, guided in the perforation 23 of the support, and provided at its upper end with a head 24, which is arranged toengage the lever 11. The lever 11, which is ada ted to swing vertically, is pivoted at one end yabolt 25 to one of the side faces of a bar or member 26 of the support 9, and its free end 27 is bent laterally and is arranged above the head 24 of the rod or plunger 22. As the laterally bent end of the lever 11 is arranged in the path of the vertically movable rod or plunger 23, the lever will be swung upwardly when the float engages and lifts the rod or plunger 22. The switch arm, which is arranged at an angle to the lever 11, extends beneath the bar or member 26, which is provided at its lower face with a recess or open ing 26 for the switch arm. The lever 11 is provided at a point intermediate of its ends with a notch 28, forming a shoulder for engaging the switch arm 1 for holding the same against the contact 6 for closing the circuit. When the lever is swung upward through the upward movement of the float and the plunger 22, the shoulder 28 is carried out of engagement with the switch arm, which will then be thrown to its open position by the coiled spring 7.
The lever 11 is adapted to swing downwardly by gravity as the water falls within the tank, and a cord 29, or any other suitable operating means may be employed for swinging the switch arm from its open to its closed position. 7 The lever 11 will automatically drop into engagement with the switch arm when the latter is swung in its closed position, it the float is out of engagement with the vertically movable rod or plunger and the latter is at the limit of its downward movement. The free end of the switch arm is also provided with a suitable knob to enable it to be readily operated by hand.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
1. The combination of a circuit having a switch arm for opening and closing it, a spring for automatically actuating the switch arm to open the circuit, a lever provided with means for holding the switch arm in its closed position, said switch arm being movable independently of the lever to reset it, a float, and means arranged in the path of and operated by the float tor actuating the said lever to release the switch arm.
