Application tiled May 22, 1925. Serial No. 32,@9

This invention relates to hydrometers, and particularly to a hydrometer of the syringe type such as is used .in testing battery fluids, radiator solutions and the like.

'llhe primary object,of my invention is to provide convenient means for suspending and supporting the hydrometer when not in use.

A further object resides in so arranging the lo parts that the suspended hydrometer will be supported in a manner to prevent leakage or dripping of any liquid, usually acid solution, which may remain after use.

Another object lies in providing a hydrom- 35 eter structure which can be used without danger of frangible portions thereof being broken or damaged.

Yet another object is to so construct the supporting means that it can be embodied with various types and constructions of hydrometers.

A still further object is to provide a supporting means which will function eciently for suspension of the hydrometer, and which 'will prevent. the instrument from. rolling when laid down.

With the above and other objects in view, which will be apparent to those skilled in the art, this invention includes certain novel features in construction andcombinations of parts which will be set forth in connection with the drawing.

rJlhe parts as illustrated in Figs. 1, 2 and 3, of my present invention are embodied with a syringel hydrometer structure similar to that sho-wn in Patent No. 1,245,449, however, it is to be understood that this invention can be embodied with substantially any and all types of syringe hydrometers.

The transparent barrel or jar l having the hydrometer gauge 2' therein has a bulb 3 at one end, and the housing 4 at the remaining end, this housing being provided with an elongated tip or spout 5 of relatively small diam-eter to be fitted through a battery cell opening or into any other receptacle containing the electrolyte or other duid to be tested.

@n one side of the elongated tip or spout 5 l mold or otherwise form a loop 6 adjacent the housing 4, and at such a position that the size of the relatively small tip or spout is not increased and no projection or extension is odered which would prevent or hinder the free insertion and removal of the tip or spout into and from the opening of a receptacle. lin practice ll have found that the housing 4, tip 5, and suspending loop 6, can be molded to be integral, but it is possible that the loop 6 might be made as a separate part and might be vulcanized onto or otherwise associated with the tip and housing. When a hydrometer constructed as set forth above is to be used the loop 6 does not in any way interfere,

and when the hydrometer is to be suspended it can be hung upon a nail 7,- or upon any other support or projection, after the manner illustrated in Fig. 2. As the bulb 3 and the housing 4 project beyond the barrel or jar l, of glass or other frangible material, and are of larger diameter, the hydrometer will be suspended with the frangible portion l entirely out of contact with the wall 8 or other member or structure in which the supporting nail 7 is held.

As shown in Fig. 3, the housing 4' has the tip or spout 5 extending therefrom,land the parts are substantially the same as illustrated in Fig. l, with the exception that the suspending loop 6 is located on the side of the housn 4 at a point adjacent the connection of the ousing with the frangible barrel or 'ar l. p As illustrated in Fig. 4, the ho al.; il diS- pensed with and the tip 9 is carried by a sleeve 10 adapted to be tted over one end of the glass barrel or jar, and the suspending loop 11 is located at the base of the tip or spout 9 where the same widens out to give the increased diameter of the sleeve 10.

Fiv. 5 shows a hydrometer structure substantlally the same as Fig. 4 with the exception that the suspending loop 11 is provided on one side of the sleeve 10 and the tip or spout 9 is thus entirely unobstructed throu hout its length.

Wil the particular hydrometer structure shown in Fig. 6 the tip or spout 12 is carried by a sleeve 13 which lits over the end of the barrel or jar, and a plug 14 is inserted within the open end of the barrelor jar. The sus-k pending loop 15 is in this instance located atthe base of the tipl or spout 12.

The disclosure in Fig. 7 is similar to the showing in Fig. 6, and here the suspending loop 15 is located on one side ofpsleeve 13 to avoid any projection on the tip or spout 12. In each of the forms of hydrometer as hereinbefore described the float barrel 1 is adapted to be fitted intoand held within a cap or cup portion formed on the end of the housing 4 or within the sleeves 10, 10', 13 and 18. The ioat barrel can be provided with a bead around its end and the cap or cup portion would then have a corresponding groove, or this connection can be made in any other desired manner, such connections being old and well known in this art.

In Fig. 8 the tip or spout 16 is carried by a ilange 17 and this ange 17 has a plug 18 which is fitted within one endv of the glass barrel or 'ar. The suspending loop 19 is located att e base of the tip or spout 16 adjacent flange 17.

It is referable that the suspending loop be forme to project radially with respect to the remaining portions of the hydrometer structure as in this relation it will extend to offer an obstruction to prevent the instrument from rolling when the hydrometer is laid down.

While I have herein shown and described vmy invention incorporated with certain speciiic types and constructions of syringe hydrometers, and havesuggestedonly certain other possible adaptations, it will be appreciated that a hydrometer constructed in accord'- ance -with my invention can be suspended t or spout up ermost so that an acid electro yte or other uid retained in the barrel after use will notdrip therefrom, and

it will be appreciated thatmy invention can be employed with and embodied in a number of other types and constructions of syringe the closure member projecting radially therel from to prevent the instrument from rolling when laid down.

2. With a syringe, hydrometer having a liquid `spout at one end, a supporting loop adjacent the base end of the spout to provide for suspension of the hydrometer with the spout uppermost, said supporting loop projecting radially as a stop to prevent the instrument from rolling when laid down.

3. A syringe hydrometer comprising two end members composed of non-frangible flexible material and one of which is cup-shaped and designed to encase a hydrometer gauge and an intermediate :trangible barrel, the end members including projecting parts adapted to maintain theintermediate rangible portion out of contact with a plane surface, and a supportingy loop on the cup-shaped end member by which the hydrometer can be suspended, said supporting loop project-ing laterally from said member to prevent the instrument from rolling when laid down.

4. The combination with the barrel of a hydrometer syringe, of a cylindrical rubber member surrounding the barrel and having a projecting perforated ear. 5. The combination with a hydrometer barrel of a ring surrounding a part of the barrel and having an eye for 'suspending the Same from a support, the ring and eye being located at such a point that the syringe will hang in an inverted position when suspended by the eye.

6. rIhe combination with the barrel of a hydrometer syringe of an annular member fitting on the barrel and having a projecting perforated ear. y I

7. A hydrometer syringe having a perforated'ear projecting therefrom as a suspendingloop, said ear being located between the center of gravity and the inlet end of the syringe to hang. said syringe in an inverted positionwhen suspended by the ear.

In testimony whereof I hereunto alix my LEO EDELMANN.
