In the drawings: Figure 1 is a view in perspective showing a The primary object of my invention is to pro vide, with a hydrometer of this type having a transparent liquid receiving barrel, a suction bulb associated with said barrel and having an open ing therethrough to give access for cleaning the 10 barrel, and closure means for said opening to permit the instrument to be used as an ordinary syringe hydrometer. Another object is to provide a hydrometer hav ing a suction and compression bulb of substan 15 tially usual form, except that said bulb has an opening therethrough substantially in line with the opening of the transparent barrel so that the ?oat can be removed and the transparent barrel can be cleaned by the use of a brush, swab, or other implement, without the necessity of removing or disassembling the bulb, nozzle, or other portions from the transparent and ordi narily frangible barrel, together with means for closing the opening. 25 Still another object is to so construct the bulb and the closure means therefor that the bulb can be applied to and used with substantially any and all forms and types of hydrometers, thermo hydrometers, and like instruments, without re-v designing and reconstruction or rearrangement of the parts. Yet another purpose is to provide a closure member for the clean out opening having asso ciated therewith means to be interposed to pre 35 vent movement of a ?oat element into the bulb, while at the same time permitting ready and free use of the bulb for drawing in and expelling a quantity of liquid desired to be tested in the liquid and float barrel.

Fig. 8 is an enlarged perspective view showing a modi?ed form of closure. , As the parts are illustrated in Figure 1, the liq uid barrel l is made of a piece of cylindrical tubu lar glass, or of other suitable transparent mate rial, and a ?oat element 2, which can be of any desired type and form and construction, is located within the transparent barrel i. A nozzle por tion 3 is ?tted at the intake end of the barrel l, and a suction and compression bulb ii is ?tted at the other end of the barrel i. This bulb 3 can be of any desired form, construction, design and shape, and can be made of any suitable material. Ordinarily vthe bulb Ii will be made of elastic 35 rubber, or of similar material, and the bulb Ii is ?tted at the end of the transparent barrel i so that the end of the barrel is entirely open and unobstructed. The bulb ll has an opening 5 formed therethrough preferably substantially Yet another object resides in so constructing the closure member or closure portion that this member or portion can be readily ?tted in place and can be as readily and conveniently removed, to thus give free and clear access for placement and removal of a ?oat element and for insertion axially aligned with the tubular opening of the barrel I, and this opening 5 is of su?icient size to permit insertion and withdrawal of a brush, and withdrawal of a brush, swab, or other imple ment used to clean the inner wall of the trans made su?iciently large to permit insertion and parent liquid barrel. ment 2 here illustrated. As the parts are illustrated in Figs. 1 and 2, I 50 have shown an internally screw threaded ring 8 inserted and secured within the opening of the bulb 6, and the closure member for this opening With the above and other objects in View, which will be apparent to those skilled in the art, my invention includes certain novel features of construction and certain new arrangements and associations of parts which will be herein 55 after more fully set forth in connection with the swab, or other cleaning implement to be em ployed in cleaning the inner wall of the trans parent barrel l. Also, the opening 5 can be removal of a ?oat element, such as the ?oat ele is here illustrated as being a cap or plug ‘5. The cap or plug ‘l is provided with external screw 2 2,124,080 threads to ?t the internal screw threads of the ring member 6, and these mating threads can be of straight type or of pipe thread type, it be ing the purpose to so form the closure plug 7 and so associate this plug with the bulb 4 that the opening into the bulb will be closed when the bulb is in use, and the closure can be readily re moved when it is desired to clean the barrel I. Ordinarily, a perforated plug or other stop 10 means is ?tted at the end of the barrel l to keep the stem of the ?oat 2 from moving into the bulb 4, and it will of course be appreciated that a per forated plug or other separate element of this character cannot here be readily used, since it is 15 essential that the adjacent end of the barrel i be open and unobstructed when the closure ‘1 is removed from the opening 5. With this in mind, I provide a stem 8 extending from the closure member ‘I and provided at its end with a per 20 forated ?ange portion or head 9, which ?ange portion is disposed in such, spacing from the closure member 1 that when this member 1 is in place the ?ange portion 9 is disposed at the end of the barrel I opening into the bulb 4‘, to thus 25 prevent movement of the stem or any portion of the ?oat element into the bulb 4. As the parts have been described, the ring 6 and the plug or closure member 1 can be con veniently made of metal, or of any other suitable material. The stem 8 and extending stop portion 9 can be made of soft rubber, or of any other suitable material, and these parts can be readily and conveniently assembled with the closure member ‘I in the manner shown in Fig. 2, or in 35 any other way that may be desired. As shown in Fig. 4, the plug or closure mem ber ‘I is provided in its outer end with spanner openings l0, and a wrench member H has span ner pins l2 thereon to be ?tted in the openings 40 Ill so that the wrench can be used to readily ro tate the closure member ‘I in turning the screw threaded portion thereof into the screw threaded opening of the ring 6. With the construction shown in Fig. 3, the bulb 45 I 3 is illustrated as having an internally screw threaded ring M, of hard rubber or of other suit able material, vulcanized or otherwise secured within and around the clean out opening into the bulb I3. The closure member I5 can be made of 50 vulcanized hard rubber, or of other suitable ma terial, and the stem portion I6 and the extending ?ange-like stop I‘! can be conveniently made of soft rubber, or of any other suitable material. In Fig. 5 I have disclosed my invention applied 55 to and used with a thermohydrometer of the con struction and form disclosed in Patent No. 1,965,456, granted July 3, 1934 upon an applica tion of Leo Edelmann. In this adaptation, the transparent liquid and ?oat receiving barrel I8 60 has a thermometer housing barrel i9 disposed closely adjacent thereto and held in place by a retaining member 20. The syringe bulb 2! is ?tted to the suction end of the transparent barrel l8, and this bulb 2|, and the parts associated 65 therewith, can be conveniently constructed and assembled and used in substantially the manner described in connection with Fig. 2. In Fig. 6 of the drawings the transparent bar rel 22 has the syringe bulb 23 ?tted at the suction 70 end thereof, and this bulb 23 is provided with a clean out opening 24. The bulb 23 is convenient ly made of elastic or cushion rubber, and in this instance rounded threads are cast; or otherwise formed directly in the elastic and cushion ma 75 terial, within the opening 24. A closure member 25, in the form of a plug, has similarly shaped rounded threads on the outer side thereof so that this closure member 25 can be turned into the threaded opening 24, and due to the inherent elasticity of the material of the bulb 23, this mounting and ?tting of the closure member 25 will ordinarily accomplish a proper and ?uid tight closing of the opening 24. The closure member 25 has a stem 26 extending endwardly therefrom and a perforated or notched ?anged 10 head 21 is carried at the inner end of this stem 26 to ?t within or be held adjacent to the open end of the transparent barrel 22. The portions 25, 26 and 21 may be made as a unitary structure, perhaps cast or otherwise formed from elastic 15 rubber, or with the plug portion 25, and perhaps other parts also, of vulcanized or hard rubber or of other suitable material. In Fig. 7 the syringe bulb 28 ?tted at the suc tion end of the transparent barrel 29 has a ta- _ pered clean out opening 30 formed therethrough, and a closure member 3| is made in the form of a stopper or cork, being preferably tapered to follow the taper of the Wall of the opening 30. This closure member 3| has a stem 32 extending 25 inwardly therefrom, and an outstanding ?anged stop portion 33 is carried at the inner end of the stem 3|. This stop portion 33 can have per forations or openings formed therethrough, can have the edge notched or serrated, and can be 30 formed in any desired manner to prevent posi tive closure of the suction end of the barrel 29, and to yet interpose a su?icient impediment to prevent the stem of any portion of the ?oat ele~ ment 2 from passing into the bulb 28. As here 35 shown, the closure member 3| has a head portion 34 thereon to be grasped and manipulated in in serting and removing the member 3|, and if de sired, this head portion can be knurled or other wise roughened, or can be provided with exten 40 sions or other formations to permit more ready grasping and manipulation and handling. As shown in Fig. 8, the closure member 35 can be of any desired construction, and likewise the stem 36 and the stop portion 31. The stop por 45 tion 31 is shown as an extending ?ange formation, and as provided with perforations 38 to insure a free and clear opening into the syringe bulb por tion, but as stated these parts can be made in any other desired manner. The closure member 35 has a ring portion 39 on the outer side thereof so extending that the eye or opening 40 of the ring can be employed as a loop to receive a nail or other member and to suspend or hang the hydrometer when not in use. At the same time, the portion 39 is conveniently accessible to be used as a handle or hand-hold portion for manipula tion of the closure member 35. From the foregoing it will be seen that I have provided a bulb structure for hydrometers, and a 60 hydrometer construction, that will make it pos sible to remove the ?oat and replace the same, and to have access to the inside of the transparent liquid and ?oat receiving barrel for swabbing the same out or otherwise cleaning the inner wall of 65 the barrel, without the necessity of removing the suction bulb itself or the intake nozzle portion, or of disassembling any of the parts directly con nected or associated with the transparent barrel, thus facilitating the assembly and cleaning of the 70 instrument and materially lessening the possibili ties of breakage of or damage to the liquid barrel or any other parts of the instrument. While I have herein shown and described only certain speci?c embodiments of my invention and 75 3 2,124,080 have suggested only certain possible modi?cations and changes in the form, construction, arrange ment, assembly and association of the parts, and in the materials to be used, it will be appreciated that many other changes and variations can be made without departing from the spirit and scope of my invention.
