Lnvnnine BOTTLE.
Application led February `19, 1927. Serial No. 169,633.
This invention relates to leveling bottles and, while not limited thereto, relates more rparticularly to leveling bottles such as used in connection with gas analysis apparatus and the like, and adapted to generally contain a quantity of mercury or the like, which 1s caused to fiow into or out of the bottle by gravity when the vertical position of the "bottle is changed. The leveling bottle 1s connected to a second vessel by a flexible tube and, when the bottle is lowered, mercury from the second vessel will flow into the bottle causing a suction in the second vessel, while when the bottle is raised the mercury will flow fromthe bottle into the second vessel and force gas or other fluid from the second vessel.
Heretofore leveling bottles have generally consisted of a simple pear-shaped hollow receptacle, and the mercury flow was conltrolled entirely by gravity. Therefore, when, as is often the case, a very fine control of the mercury was necessary it was needful for the operator to be very careful and at times to be very expert in order to correctly control the mercury flow, since even the slight movement of the bottle caused by the nervous twitching of the operators hand will, in some cases, cause a sufficient flow of the mercury to destroy an analysis.
The present invention has for its object the provision of a measuring bottle which is provided with means under the control of the operator, for accurately controlling the mercury flow regardless of the position of the bottle.
The drawing shows a sectional elevation through a leveling bottle constructed in accordance with my invention and connected with a burette.
Referring more particularly to the drawing, the numeral 2 designates the pearshaped hollow body of the bottle which has an open neck 3 at its upper end and contracted outlet port or opening l at its lower end opening into a tube 4 adapted to receive one end of a flexible conduit 5 for conducting the mercury from the bottle to a second vessel such as the burette 6, to which the` other end of the conduit is connected.
A n outlet tube 7 is formed integral with the lower end of the bottle around the port or opening 4, and extends upwardly within the bottle a material distance. The tube 7 is provided with a plurality of vertically spaced outlet openings 8 in its side wall, which openings are of successively larger dimensions as they progress upwardly.
The lower end of the bottle body 2 within the tube 7 and surrounding the outlet tube 4C is ground to form a valve seat 9.
A valve float tube 10 is mounted within the tube 7 and has its lower end closed and provided with a cushion face 12 adapted to be seated against the valve seat 9 to stop the flow ofk mercury from the bottle.
The tube 10 has a sliding lit in the tube 7 and as it moves downwardly past the openings 8 in the tube 7 serves to check the flow of mercury theretl'irough.
The tube 10 is provided with a oat bulb 1st intermediate its ends and is adapted to be floated upwardly as the level of mercury in the bottle is raised, and to be automatically lowered as the mercury level is lowered, thereby uncovering` and covering the successive openings 8.
The upper end of the tube 10 projects through a cushioned guide plug composed of a rubber body 15 having a glass or metal guide tube 16 therein.
While I have'shown a cushion face 12 on the lower end of the tube 10 it will be understood that this face may be omitted and the lower end of the tube ground to seat on the seat 9, if desired. It will be also understood that the float bulb 111 may be omitted, if desired, since in some instances at least the tube 10 itself will be sufiiciently buoyant to be floated by the mercury.
In operation, assuming that the mercury in the leveling bottle is at a sufficient height to float the tube 10 and it is desired to raise the level of mercury in the burette 6, the bottle will be raised so as to cause the mer cury to flow from the bottle through the openings 8 and tube 5 into the burette 6. As the level of mercury in the bottle is lowered, the tube 10 will lower so as to check the flow of the mercury through the Openings 8 thereby slowing up the flow as the desired level in the burette is approached. l/Vhen the desired level of mercury is approached in the burette, the operator may then manipulate the tube 10 by hand so as to control or entirely stop the mercury flow by forcing the cushion face 12 to engage and be seated on the seat 9.
It will also be readily understood that the tube 10 may be manipulated by the operator to control the flow of the mereury from the burette 6 into the leveling bottle.
I claim- 1. A leveling bottle for use with gas analysis apparatus and the like, comprising a pear-shaped hollow body portion having an outlet opening at its lower end, and a combined manually operated and float valve for controlling the iiow ot' fluidV Yfrom said bottle.
2. A leveling bottle for use with gas analysis apparatus and the like, comprising a pear-shaped hollow body portion having an outlet opening at its lower end, an outlet 'tube surrounding said outlet opening and formed integral with the `bottom wall ot sai d body and extending upwardly within said body an appreciable distance, said tube having a plurality of vertically spaced openings therein, anda valve member mounted in said tube and adapted to automatically cheek the flow of fluidY through said openings as the head of fluid vin said bottle is diminished.
3. A leveling bottle for use with gas analyysis apparatus and the'like, comprising a pear-shaped 'hollow body'portion having an outlet opening at its lower end, an outlet tube surrounding said outlet opening and .formed integral with the bottom wall of said body and extending upwardly within said body an appreciable distance, said tube having a plurality ot' vertically spaced openings therein, a valve seat formed at the lower end of saidoutlet tube surrounding said outlet opening, and a combined iioat and manually Operated iioat valve mounted in said outlet tube and adapted to check the iiow of iluid through the openings in said outlet tube and to control and entirely stop the low of fluid lirough said outlet opening.
4t. A leveling bottle for use with gas analysis apparatus and the like, comprising a hollow body portion having an outlet opening at its lower end, and a combined 1nanually operated and ioat valve for controlling the flow o'i fluid from said bottle, said vulve having a stem portion projecting through an opening in said bottle adapted to be engaged by the operator to manually control said valve.
In testimony whereof, I have hereunto sioned my name.
