CIRCUIT CONTROLLER FOR LIQUID GAGES.

WITNESS attomwq UNITED STATES PATENT OFFICE.
CIRCUIT-CONTROLLER FOR LIQUID-GAGES Application filed February 1, 1918.
To all 10/2/0772. it may concern:
Be it known that I, JnNNIn GroULn BLAIS- DELL, a citizen of the United States, residing at est Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Circuit- Controllers forLiquid-Gages, of which the following is a specification.
This invention relates to an improvement in circuit controllers for liquid gages.
he primary object of the invention is to produce a simple, cheap, effective and re liable device whereby an indicator will register the rise and fall of a liquid body remote from the indicator.
A. further object of the invention is to produce an electrically operated liquid gage comprising few simple parts which may be readily assembled and installed, and which will perform the functions for which it is devised with accuracy and certainty.
Other objects and advantages will appear as the nature of the invention is described, reference being had to the accompanying drawings, in which,
Figure 1 is an enlarged side elevation of the improvement.
Fig. 2 is a sectional view approximately on the line 22 of Fig. 1.
Fig. 3 is a sectional view approximately on the line 3-3 of Fig. 1.
In Fig. 1 of the drawings I have illus trated my device as applied to an ordinary motor vehicle, but in this connection it is to be stated that the same may be employed with efficiency in other connections, as for instance between the gasolene tank and the drivers seat in an aeroplane, or in fact in any place where it is desired that the rise and fall of a liquid body be indicated at a remote point from the said body. In Fig. 1 of the drawings the numeral 12 designates an arm or lever that has its outer end pivoted as at 13, and its said outer end provided with an angular segmental member 14 having its lower edge provided with teeth 15.
Below the toothed segment 14 is arranged a frame 16. The base 17 of the frame is preferably in the nature of a disk and is constructed from some suitable insulating material. To the diagonally opposite sides of the base 17 and arising therefrom are the arms 18of a substantially U-shaped member providing the upper portion of the frame. The connecting member for the arms 18 is Specification of Letters Patent.
Patented Aug. 30, 1921. Serial No. 214,954.
indicated by the numeral 19 and is provided with a central opening forming a bearing for a shaft 20. The lower end of the shaft has a bearing in the central portion of the base 17, and the outer end of the shaft has secured thereon a pinion 21 that meshes with the teeth 15 of the segment 14. It will be apparent that the rise and fall of the float swinging the lever 12 and turning the segment 14 will cause the shaft 20 to be turned.
On the shaft 20 is secured spaced collecting rings 22 and 23 respectively, each of the said rings being contacted by brushes 24 and 25 respectively, the said brushes being connected to a suitable source of current.
Secured to the shaft 20 below the ring or wheel 23 is a block of insulating material 27 which has secured to the outer face thereof spaced, oppositely extending spring wiper arms 28 and 29 respectively. The numeral 30 designates the conductor between the arm 28 and the ring or wheel 22 and the numeral 31 designates and the ring or wheel 23. The arms 28 and 29 are rounded downwardly toward the disk from their connection with the block 27 and have their ends extended outwardly, the said ends contacting with contact studs 32 arranged in spaced relation to each other concentrically of and adjacent to the periph cry of the base 17. These studs extend entirely through the base 17 and to the outer ends thereof are attached conductors 33. The conductors 33 that are connected to the studs at one end have their remaining ends passed through a disk 34 of insulating a conductor between the arm 29 7 material and then connected to coils mounted upon an iron ring 35. Mounted to be moved by the influence of the field just described is an armature in the form of a pointed plate 36 mounted upon a shaft 37 that is in turn supported by a frame 38 a portion 39 of which being formed into a dial to cooperate with the pointer 40.
I11 operation the rising and fall of the liquid causes the segment 14 to turn the shaft 20 which in its movement wipes the arms 28 and 29 over the studs 32. Thus the studs are selectively engaged for feeding current thereto. This operation causes the shifting of the field thereby moving the pointer over the scale in accordance to the rising an lowering of the level of the liquid. From the foregoing description, when taken in connection with the drawings, it is thought that the simplicity and advantages of the construction will be apparent without further detailed description.
WVhat I claim is:
A device of the class described comprising a base of insulating material, an annular series of stationary contacts carried by the base, a U-shaped frame mounted on the base and having a connecting portion overhanging said base and provided With an opening, a shaft extending through said opening and rotatably mounted on said base, a pair of spaced rings mounted on said shaft, conductors supported by said frame and engaging said rings, an insulating block mounted on said shaft, a pair of oppositely directed spring arms secured to said block and having their terminal portions extending angularly for engaging said stationary contacts, and means electrically connecting said spring arms and said rings.
In testimony whereof I afiix my signature.
