VAPOR-TENSION CONTROLLER.
SPECIFICATION forming part of Letters Patent No. 455,382, dated July 7, 1891.
Application filed September 6, 1890. ,Serial No. 364,064. (No model.)
To all whom'it may concern.-
Be it known that we, LOUIS BELL and FRANK H. ROOT, citizens of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vapor-Tension Controllers, of which the following is a specification. l
Our invention relates to mechanism for controlling the tension of a confined fluid similar to those showiraud described in our applications, 'Serial No. 336,945;filed January 14, 1890, and Serial No.'368,420, filed October 17, 1890.. As here shown and described it is made-a part of an automatic apparatus for controllinga fiuidpaSsage.
In general terms the invention consists of two chambers communicating with each other other chamber.
atone point and both having openings into the atmosphere, in combination with a flame located at or near the opening between the chambers in such a manner that when the flame is small it is entirely within one of the chambers, but when large it extends into the As the heated air from the flame rises the chamber which the flame is in determines the direction of a draft of air through the two chambers, and accordingly which one of the two chambers the heated air from-the flame will pass through. In one of the chambers'a sealed cylinder containing a volatile fluid is placed, and the tension of this fluid is controlled by varying the size of the flame, as will appear hereinafter. This tension or pressure of the fluid may be utilized A and A represent two chambers communi eating with each other through a passage a, which is located at the ends of the chambers.
' The chamber A contains a sealed cylinder B,
in which is placed a certain quantity of highly through the wall of chamber A, and extends to within a short distance and directly in front of the'opening a, so that the end of the jet will be wholly'within the chamber A.
At the upper endsof both chambers A A or, rathe'igat the end opposite theopening a,
perforations a are made to admit the external atmosphere.
T represents a thermostat comprising a chamber 1, in which is confined a highly volatile fluid. The inner wall of the chamber is movable under the pressure of the vapor. It is connected with a valve t, which controls a passagebetween a gas-supply t and a pipe i leading to the gas-jet c. The gas from supply-pipe t passesfirst i r 1 t o a chamber thence through the valve opening into a chambert thence through an opening into the pipe i There is also a passage into the pipe t directly from chamber 75, as shown. throttled by a valve 25", so that the quantity of gas flowing into the pipe i from the chamber 15 direct will be just sufficient to maintain a small flame at the jet '0.
The chamber 13 may communicate by a passage b with a chamber b, one wall of which This passage is has a flexible diaphragm, whichis connected heat ing apparatus. Now when the temperature of that apartment rises above the no r-' mal the tensionof the vapor in chamber 2 of -thet-hermostat increases and opens the valve 25', thus allowing" an increased supply of gas to flow from supply-pipe i into the pipe t and thence to the flame at c. This increases the size of the flame and the pressure of the gas drives it through the opening a between the chambers A and A, so that the heat from the flame will rise into'the chamber A andhave the tendency to establish a vacuum in the chamber 'A', thus' 'setting up admit in the.
direction of the arrows-Fig. 2, heating the chamber B, increasing the pressure therein,
cated in the apartment heated by the said and cutting off the supply of fuel to the heat ing apparatus. Whenthe temperature in the apartment lowers to the normal again, the valve 15 closes and cuts off the supply of gas,
.thus reducing the size of the flame until it is 'so small that it is fully within the chamber A. The heated air from the flame then rises into the chamber A and drawscold air other, depending upon the size of the flame at the jet 0.
Having thus described our invention, we claim-- 7 The combination, with two chambers com- 2 municating with each other at their lower ends and opening into the atmosphere at their upper ends, of a burner located adjacent to the opening between the chambers, and means for forcing the flame into one or the other of the chambers, for the purpose set forth.
In witness whereof we have hereunto signed our names in the presence of two subscribing witnesses.
