LIQUIDTESTlNG DEVICE.v

SPECIFICATION forming part of Letters Patent No. 569,783, dated October 20, 1896.

Application filed May 8, 1896. SerialNo. 590,745. (No model.)

To all whom t may concern.-

Beit known that I, JESSE O. COND, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain neuT and useful Improvements in Liquidflesting Devices, of which the following is a specification.

This invention relates to apparatus for Withdraiving samples of liquids from receptacles in which they are stored; and it has for its object to provide a simple and effective device adapted to be lowered into a reservoir to receive a sample of the liquid therein While enteringthe same, to be closed at its lower end after it is submerged,and to be Withdrawn, bringing with it a sample of the liquid.

-The invention consists in the several improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure l represents a longitudinal section of my improved liquidtesting apparatus. Fig. 2 represents a see tion on line 2 2 of Fig. l.

The same letters of reference indicate the same parts in both gures.

In carrying out my invention I provide a portable liquid-receptacle comprising a body on, which is here shown as a cylinder and is preferably made of glass, and heads a' a2, which are preferably circular disks of metal grooved to receive the ends of the cylindrical body a, said heads being connected and held against the ends of the body a by longitudinal rods 0.3. The upper head ct' is provided with a permanently open airpassage a4, which permits air to escape from the receptacle when it is being lled and to enter when the liquid contents are being discharged. In the bot tom head a2 are a series of ports a, which permit liquid to enter the receptacle through the bottom head when the receptacle is lowered into a body of liquid.

b represents a stud which is fitted to turn :in a socket formed in the center of the bottom head di. To said stud, above the head o2, is aixed a circular valve c, having a series of ports o', which are arranged to coincide with the ports a5 when the valve is in one position, said ports a5 being closed by the valve when the latter is turned to another position. The valve bears closely against the upper surface of the head c and is provided with suitable packing material, which enables it to tightly close the ports a5 when adjusted for that purpose.

b represents an arm affixed to the stud b below the head a'. To the outer end of said arm is aiiixed one end of a flexible .cord or chain d', which extends through guides at d' d? in the heads a2 and a'. The head a is provided With eyes e e, with which are engaged the ends of a bail f, to which' is attached a cord or chain g of any desired length. The chain d has a ring d3 at its upper end, with which is connected a cord d4, which may be of the same length as the chain g.

The lower guide d" is arranged to hold a portion of the chain d in a horizontal position, so that a pull on the cord d4 will close the valve, as hereinafter described.

In operating the device the valve c is turned to open the ports a, as shown in Fig. 2, and the receptacle is lowered into the liquid-reservoir, the liquid entering the receptacle through the ports a5 as the receptacle sinks into the liquid, the air at the same time escaping through the air-passage a4. The operator, While the receptacle is submerged, by pulling on the cord or chain d4, closes the valve through the arm b' and stud b, thus confining a charge of liquid Within the receptacle. The receptacle may now be Withdrawn, bringing with it the charge of liquid which it has received. The receptacle may be emptied after its Withdrawal by opening the valve.

i represents a thermometer which is attaehed to an extension of the stud b, which projects from the bottom into the interior of the receptacle, said thermometer aifording a means for readily determining the temperature of the liquid. The stud b is therefore utilized both as a means for pivotally securing the valve to the receptacle and for supporting a thermometer therein.

The stud b has a shoulder b3 above the valve and is detachably secured by a nut b4 below the head o?. Hence the thermometer and stud may be readily removed should occasion require.

By reason of the construction of the valve the sample liquor iioWs easily into the cylinder, because of the relatively large area of opening afforded by the ports a5, distributed evenly over the bottom of the cylinder. A

small movement of the radial lever and of the valve closes a large total valve-opening, be-

cause of the number and arrangement of the ports.

I claiml. A liquid-testing device comprising a receptacle having' a liquid receiving and discharging port in its bottom, an air-passage in its upper portion, and a bail or handle whereby it may be suspended Within a reservoir; a stud passing through the said bottom and itted to rotate therein; a valve aflixed to the stud and adapted to open and close the said port; a laterally-projecting arm afiixed to the stud below the bottom of the receptacle; a cord or chain affixed to said arm, and guides on the receptacle arranged to hold a portion of the said oord in position to cause a pullon the cord to close the valve.

2. A liquid-testing device comprising a receptacle having a liquid receiving and discharging port in its bottom and an air-vent in its upper portion, and adapted to be suspended in a reservoir, a stud detachably connected to said bottom and fitted to rotate therein, said stud having` an extension projecting' above the bottom into the interior of the receptacle, a valve afXed to the stud and adapted to open and close the said port7 and a thermometer afxed to the said extension and su pported thereby Within the' receptacle.

In testimony whereof I have signed my name to this specification, in the presence or two subscribing` Witnesses, this 25th day of April, A. D. 1896.

JEssE o. CONDE.
