COMBINED WATER AND GAS CONNECTION AND GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 462,292, dated November 3, 1891.

Application filed December 23, 1890. Serial No. 375,626. (No model.) i

To all 1071 0172 it may concern:

Be it known that I, ROBERT P. BARNS'IEAD, a citizen of the United States of America, and a resident of the city of Boston, county of Suffolk, and State of Massachusetts, have i11- vented a certain new and useful Improved Combined \Vater and Gas Connection and Gas-Regulator to be Used for Hot -\Vater Apparatus, &c., of which the following is a full, clear, and exact description.

The improved combined water and gas connection and gas-regulator of this invention is particularly designed for hot-water apparatus, and in substance it is composed of a vertical casin g or shell in upper and lower sections adapted to be connected together and its upper section at its upper end closed and its lower section at its lower and open end adapted to be connected to a boiler for water, &o.; a vertical closed reservoir for niercuryor such like held in and surrounded by an open space of the shell that at its upper and lower ends, respectively, is closed and open, preferably surrounded by a fixed tube of larger diameter that is closed at both ends, and a fixed and inner tube held on and projected downward from the upper end of the mercurial reservoir and its upper and lower ends both open, and respectively one to the inside and the other to the outside of the reservoir, in combination with a horizontal passage across the upper end of the mercuryreservoir and at its opposite ends, respectively, adapted to be connected to a gas-supply and to a gas-burn er and partitioned off into two horizontal sections, always in gas communication by a j et-hole of the partition,

and its gas-supply and gas-burner connected sections respectively in communication with open upper end of said-inner tube and with the space between it and said mercury-reservoir; two side openings of the shell, one located toward upper end portion of and the other toward and preferably below said mercury-reservoir and respectively adapted for connection with a water-supply under pressure and with a return-pipe of water-pipes arranged outside of the shell for automatic circulation through them of water suppliedto them from the boiler of theapparatus, and two pipes respectively continuous with the lower end and with said lower side opening of shell and both leading into the boiler, the one to a level near the lower portion and the other to a level halt-way or so of the height of the boiler; and, again, this invention in hot-water apparatus consists in the combination,with a closed vertical reservoir to con tain, preferably, mercury or other material quickly sensitive to changes in temperature, and which is placed as to the boiler of the apparatus for its contents to be acted on by the temperature of the water in said boiler, and with a supply for gas, &c., to be used to heat the water or other liquid in the boilerand suitably adapted for the gas preferably to be only partially shut off by a rise and to be fully opened by a fall of said mercury, of a spiral way or passage about and along said mercury-reservoir and at its upper and lower end portions respectively in communication with a water-supply under pressure and within the boiler, and, furthermore, in an improvement in detail, as hereinafter fully appears.

In the drawings forming part of this specification, Figure l is a central vertical section of the combined connection and gas-regulators of this invention in all its parts, except that its pipes leading into the boiler are broken cit intermediate of their length and the boiler is shown as broken off. Fig. 2 is a horizontal section in detail, line 2 2, Fig. 1. Fig. 3 is a vertical section in detail, as will hereinafter appear. Fig. iis a vertical section of a hot-water boiler and also of some of the contrivances of this invention applied to the boiler, the remainder of the parts be ing shown in side elevations.

In the drawings, A A is a vertical shell or casing in upper and lower sections, suitably adapted to be connected togethertor illustration, Fig. 1 by simply resting the upper upon the lower and Fig. 3 by screwing one upon the other. The lower end A of the lower section A is open and is adapted to be screwed into a screw-threaded opening at the top of a water-boiler B.

O is a reservoir for mercury or other material quickly sensitive to changes in temperature. This reservoir 0 at its upper end portion is screwed into a screw-threaded socket at the lower end of the upper shell-section A, and extends therefrom down into and through IOO a greater portion of the height of the lower section A wherein from end to end it is surrounded by a space A which is closed atits upper end and at its lower end is continued by the full chamber A of the shell located below the lower end of the reservoir.

D is a vertical tube which surrounds the mercury-reservoir and is located in the space A between it and the shell A This tube-D at its'upper open end is fixed in the upper end of the lower shell-section A and at its lower end it is closed and also below the bottom of mercury-reservoir C.

D is an open space between reservoir 0 and vertical tube D, surrounding it, as stated.

E is a vertical tube open at both ends. This tube is of smaller diameter than and is located in the upper portion of the reservoir, and its upper end is held on the lower end of the upper shell-section A, and its lower end is intermediate and preferably midway or thereabout of the height of the reservoir.

F is a horizontal gas-passage across upper portion of upper section A of shell and adapted at each end for gas-pipes F F, Fig. 4, to be connected thereto, and at one end portion F by pipe F to a gas-supply, (not shown,) and at t-heother end portion F by pipe F to a burner F suitably arranged for heating water in the boiler. The upper end of the inner vertical tube E of the reservoir opens into the end portion F of the gas-passage F, connected with a gas-supply, and at the side of this tube toward the other end portion F of the gas-passage F there is a cross vertical partition F dividing the gas-passage into two distinct horizontal sections F F one F the section connected to gas-supply and the other F the section connected to gasburner, and this section F is in connection 'with the mercury-chamber 0 about its inner vertical tube E by an opening G in the lower end of the upper section A of shell and with the gas-supply section F by a port or aperture a. To fully open or to fully close or otherwise to regulate the superficial "area of this aperture, Fig. 2, a regulating-screw H is provided. This screw H screws into and through the wall of the gas-burner section F of the gas-passage, and it has conical tip H adapted for the jet-hole a, so as to fully open or close it or otherwise regulate it, all as is obvious without further explanation.

J is an opening at one side of the lower section A of shell and near upper portion of and in communication with the space D directly about tube D, surrounding the mercury-reservoir. This opening J is for the connection of a supply-pipe (not shown) for water under pressure with the space D of shell,

said space being in fact a part of the whole space between shell and mercury-reservoir. This space D below opening J has adown ward-windin g spiral way K, continuing to the lower end of the outer vertical tube D, Where it opens to the full chamber A of the shell, all so that the water entering into the space D of the shell is forced to wind its way around the tube D in its passage downward through the shell A.

L is a side opening of the shell A at or near lower end portion of spiral way K, and it is for connection of the return-pipe M, making one of the two pipes M N, the other being entered into the top of the boiler, that are, as well known, together arranged for an automatic circulation of water through them from the boiler to the valve and nozzle at which the water is to be drawn oif.

O is a vertical pipe connected with inner end of lower side opening L of lower section A of shell A.

P is a pipe connected with the lower open end of said'shell' section. The pipe 0 is within the pipe P, and the pipe P terminates near the bottom 13 0f the boiler B and the pipe 0 terminates intermediate and preferably midway of the height of the boiler.

As particularly shown, the lower section A of shell is of itself divided into upper and lower sections screwed together and having the line of division just below the upper side openingJ of the shell. This division is desirable, as it enables the upper portion of said section A to be removed at pleasu're,provided, of course, first thatthe water-supply has-been shut oil": from the side openingJand otherwise the apparatus has had its gas connection properly prepared therefor. Vith this'portion of lower shell-section A detached the tube D and also the mercury-reservoir are removed, and thus the chamber of the lower portion of same section is open for inspection, cleaning, dtc.

In the connection, which as a whole has been now described plainly, the mercury of the reservoir is subject to the temperature of the water in the boiler, and thereby made either by its full rise to shut-oft and by its fall to open fully or partially, as the case may be, the main supply of gas to the burner, the gas in the first instance then passing to the burner only through the port a and in the second instance through said port and the inner tube of the reservoir, and thence from the reservoir through the opening G into the gas-burner section of gas-passage, all according as required, and in any event and at all times the gas-burner is supplied with gas. Again, plain-1y when theouter tube D is used the mercury-reservoir can be detached by simply detachingthe upper section A from the lower section A of shell, first, of course, having disconnected the gas-pipes at the gaspassage F and stopped up its opposite end opening, which obviously is advantageous-a very important feature, in that it enables the IIO mercury-reser'v oir to be detached without disturbance of the Water connections. Again,

plainly the said connection is compact and carries practically in one whole all parts for the gas connections and the passages of the gas, as stated; also all parts for water connections, except that for one pipe N of the automatic circulating-pipes M N and the mercuryreservoir, the parts being all practically within and embraced by one outer shell or casing A, and when that is attached placing all in position.

The outer tube D surrounding the mercuryreservoir constitutes an essential feature of this invention; but in so far as relates to the result produced by the down ward spiral run of the water from the supply to the boiler it can be as well produced by removing said tube and having the water-supply run in direct contact with the mercury-reservoir. (See Fig.
