The invention consists of a hydrometer specially designed for revealing the efficacy and charge of an electric accumulator by means of control of the electrolyte density process.
The hydrometer of this specification consists essentially of a tubular receptacle provided with a suction bulk for the electrolyte, said receptacle containing a body that remains submerged in the liquid, which body is united to a horizontal arm that at its other extremity supports a movable perpendicular axle connected to a needle that moves over a graduated scale, said axle being provided with ,very sensitive bearings or pivots, so that the whole assembly is mounted on a horizontal axis allowing a vertical oscillatory movement within a container resulting from the impulse received by the body upon being submerged in the electrolyte.
In reaction to this oscillatory movement by the loss in weight, a magnetic system is incorporated in order that the submerged body shall adopt distinct positions in height according to the density of the electrolyte being measured.
, The pointer situated in the center of the aforementioned indicator hand, moves over a graduated sector, the reading of which indicates the density of the electrolyte. In the drawings:
FIG. 1 shows a front view in elevation of the device.
FIG. 2 is a conventional cross section of same taken along the line A-B.
FIGS. 3 and 4 illustrate the details of the magnetic reaction system.
Referring to the drawing, there is disclosed a glass or plastic cylindrical body 1 which serves as a receptacle for the electrolyte, to which body 1 there is joined a body 2 generally of the same material, which body 2 encloses and supports the axis of the movable body, the bearings or pivots, the indicator hand and pointer and the magnetic armature, The body 2 defines a narrow compartment 2' in direct communication with the interior of the tube 1.
The compartment 2' has an axle 3 rotatably disposed therein, the axle 3 being disposed for rotation about a horizontal axis which is substantially perpendicular to the longitudinal direction of the tube 1. The axle 3 is fixedly secured to one end of a substantially horizontally elongated arm 14, which arm extends radially from the axle 3 and extends into the interior of the tube 1 and has a submergible body 13 fixedly secured to the other end thereof. The body 13 is movable in a vertical direction within the tube 1 as illustrated by dotted lines in FIG. 1. The axle 13 also has a pointer or hand 12 fixedly secured thereto and extending radially therefrom substantially in the vertical direction, which pointer is adapted to move relative to the graduated scale 16 formed on the body 2. The axle 3, pointer 12, body 13 and arm 14 thus substantially comprise a rigid one-piece member. The axle 3 also has a small soft iron armature 8 (FIG. 2) fixedly secured thereto.
The body 2 is provided with an adjustable screw-type pivot member 4 on one side thereof, which pivot member has a suitable tapered support recess 17 formed in the inner end thereof. A similar tapered support recess 18 is formed in the body 2 opposite the pivot member 4. The support recesses 17 and 18 are adapted to rotatably receive therein the . needle bearings 19 and 20, respectively, which are secured to and extend outwardly from opposite ends of the axle 3.
The body 1 is provided with a rubber suction bulb 10 for suctioning the electrolyte into tube 1, and a mouthpiece 11 of flexible material for the entrance of same.
The screw 9 passes through the elongated slot to allow the support magnet 5 to be moved in order to vary the magnetic plane.
Although a particular preferred embodiment of the invention has been disclosed in detail for illustrative purposes, it will be recognized that variations or modifications of the disclosed apparatus, including the rearrangement of parts, lie within the scope of the present invention.
The embodiments of the invention in which I claim an exelusive property or privilege are defined as follows:
1. An improved hydrometer, comprising: a tubular receptacle having openings at opposite ends a closed casing fixedly secured to the side of said tubular receptacle, said casing comprising a narrow vertically elongated compartment fixedly secured to and extending longitudinally along one side of said tubular receptacle, said casing having a hollow interior disposed in communication with the interior of said tubular receptacle;
an axle rotatably disposed within the interior of said casing and supported on said casing for rotation about a substantially horizontal axis which is substantially perpendicular to the longitudinal direction of said tubular receptacle, said axle having an iron armature fixedly secured thereto for rotation therewith and contained within the confines defined by the outer periphery of said axle;
said casing having a tubular support portion extending outwardly thereof in which is rotatable positioned said axle, and bearing means internally of said tubular support portion coacting between said tubular support portion and said axle for rotatably supporting said axle relative to said casing;
an elongated arm totally disposed within and extending substantially horizontally between the interior of said casing and the interior of said tubular receptacle, one end of said arm being fixedly secured to said axle and the other end of said arm being fixedly secured to said body, whereby vertical movement of said body within said tubular receptacle causes a corresponding pivoting of said axle about said horizontal axis;
