Application filed April 11, 1924. Serial 110/705,?66.
To all whom it may concern:
Be it known that I, WILLIAM ELBERT SExToN, a citizen of the United States, residing at Baltimore, in the State of Mary- 5 land, have invented certain new and useful .an improved construction and arrangement,
1 of burner-piping, manifold and distributing piping for supplying gasto the various burners, or to roups or sets of burners and to so. arrange t e piping that a single range or a battery of ranges may'besupplie'd with Another object of the inve'ntion is to provide an improved group-arrangement of burners and to connect the burners in a group with the gas-supplyso that all the burners'of a group or only a portion thereof as desired may be operated through the- 4 'medium of a single valve.
- A further object of the invention is tov provide an improved construction of gassupply main.
With these, and other objects in view, the invention is illustrated in the accompanying drawings, wherein,- a
'Fig, 1 shows a range in front elevation to which the improved arrangement of burn ers, supply-pipe and branch pipes are at- Qtache Fig. 2 illustrates a horizontal sectional detail across the top of the range and above the burners,th e section being taken on the line 2-2 of Fig. 1.

Fig. 11 shows a vertical sectional detail through the front and rear burner-supporting means, as the same would appear if viewed on the line 1111 of Fig. 10. Fig. 12 illustrates a vertical sectional detail of the lower b urner-su porting plates as the same would appear i viewed on the line 1212 of Fig. 10, and
Fig. 13. shows a horizontal sectional de; tail through said lower' burner-supporting plates,the section being taken on the line 13 13 of Fig. 10. a
Referring to the drawings the numeral 12, designates a front plate of the range which latter has an upper burner compartment 13; a lower burner com artment 14, and an oven between the sai lower compartments. I
A door 15, having novel features of construction and operation, but forming the subject of a separate application,"is ivo'tally sustained at 16, in suitable brac etupper and provi e a battery or a plurality of ranges in a row, and it is also desirable that the fuel-gas be supplied so as to avoid a multiplicity of pipes and in such a way that an entire group of burners or only certain burners of such group may be used or not as desired.
It is therefore an object of the present invention to provide a novel arrangement of burners and gas-supply pipes, branches and valves, whereby fuel gasmay be supplied to a set or group of burners, or to certain burners of a group. of burners by means of .a single control valve and without unneces sary use of burners.
With these objects in view, I provide a horizontal upper main pipe 26, a lower horizontal main pipe 27 and a vertical pipe 25 which connects said upper and lower main g v his vertical pipe 25 1s preferably provided with a valve 10 by means of which gas to the lower main 27 may be cut'ofl' without interrupting the passage of gas through the upper main.
he upper main 26 extends horizontally across the front of the range from one vertical side edge to the other of the range, and said upper main is provided with a lateral flange 11 at its upper inner side which flangeextends toward and is flush with the top 21 of the range and seats closely against the rim-edge of and around said range-top. By thus seating the flange 11 of the upper main against the rim edgeof the range-top I avoid the formation of a vertical space between said upper main and the said range-top into which space grease and food materials would collect.
Each upper main 26 is provided on its under side, and midway between its ends,
with so-called pads 29 and 30 respectively, the pad 29 being located between two pads 30, and each of the pads 30 has a port extending downwardly therethrough for the passage of gas from the main as will presently be more clearly explained.
To the under side of one ad 30, there is attached one end of a branch pipe 31 while a similar branch pipe 32 is attached to the underside of the other pad 30.
The two'branch pipes 31 and 32 extend downwardly from the respective pads 30 and one of these pipes 31 isturned laterally in one direction while the other pipe 32 extends laterally in an opposite direction. Both of these branch pipes however are located directly beneath the upper main 26,
" i and extend in opposite directions across the upper front portion of the range, as clearly shown in Fig. 1 of the drawing. 1
The branch pipes 31 and 32 are both of novel construction and the pipe 31 is provided with a specially-constructed valve 33 while the pipe 32 has a similar constructed special valve 34 which valves are interposed between and control the passage of gas from the upper main 26 to said branch pipes.
It is important to note that the branch pipes 31 and 32, which are of like construction, are interiorly divided by a longitudinally-extending partition 35 whereby to produce two longitudinal chambers or passages 36 and 37 respectively in each of those pipes, as may clearly be seenin Fig. 3, 4 and 5 of the drawings.
The outer ends of the branch pipes 31-32 are supported in brackets 28 which latter also sustain the upper main, and said outer branch pipe-ends are closed in any suitable manner and the longitudinal chambers or passages 3637 are entirely separate and" seatis provided with a port 39 that communicates with the port 40 in the pad 30 of the main 26 and each seat also has two ports 41 and 42. w.
The valve-seat port 41, (see Figs. 3, 8 and 9) opens into the longitudinal chamber or passage 36 is the branch burner- pipe 31 or 32 while the valve-seat port 42 opens into the longitudinal chamber or passage 37 in said branch burner-pipe.
It is therefore to be understood that valve port 41 is located at one side of longitudinal partition 35 while port 42 is on the opposite side of said partition.
The valves 33 and 34, which are of like construction, each have a port 43, to coact with port 39 in the valve-seat and said valves also have ports 44 and 45 to coact with the ports 41 and 42 that open into the chambers or passages 36 and 37.
The valves 33 and 34 are obviously capable of being rotated or turned in the seats 38 and, .as shown'in Fig. 3, when the valve is in one position gas from the main 26 may pass through ports .40, 39, 43, 44 and 45, and through ports 41 and 42 to both chambers 36 and 37 in the branch burnerpipe; that when said valves 33 or 34 are turned to the position shown in Fig. 8 gas from the main will pass through ports 40, 39, 43 and 44 and then through port 42 to latter position of the valve will cut off the gas to one-passage or chamber 36 while gas may flow to the other passage or chamber 37 By reference to Fig. 9 of the drawing it will be noted that the valve 33 is shown turned to a position where no gas can pass from the main through port 39 and also these passages is controlled by the valvethat both ports 41 and 42 to the passages 36' and 37 of the branch burner-pipe'are cut off from the gas supply.
The object in providing the two passages 36 and 37 and the valve 33 or 34 that will control the flow of gas to one or both or to neither of said passages 36 or 37 is so that,
through the operation of a single valve, certain burners of a group of burners may be cut off while one or more burners of thesame group may be supplied with gas and allowed to burn.
The burners under the range-top are arranged in groups 23 and 24,there being in this instance four burners in each group, although the numbergmay obviously be varied.
The burners, say burners 23 of the one i group, are connected to the branch-pipe 31 7 so that some of the burners of the group will communicate'with passage 36 of said pipe 31 while other burners of the same group will communicate with the passage 37 in said pipe 31.
The manner of connecting the several burners of a group with the branch-pipe 31 is illustrated in Figs. 3,4 and 5 of the 1 drawings and to distinguish certain of these burners from others of the same group in 'these particular views of the drawing, I
have designed two of them 23 and the other two are designated 23".
1 By reference therefore to said Figs; 3,v
4 and 5 it will be noted that the burners 23 of the group '23 are connected to pipe 31 so as to communicate with the passage 36,-
the connection being by means of the ports '46, and the burners 23 are connected to the passage 37 of thepipe 31 through the ports 47.
In this way some of the burners of group 23 are supplied withgas from passage 36 of the branch-pipe 31; while other.burners of the same group are supplied with gas.
from passage 37- of said branch-pipe 31, and the supply of,gas to one or both of 33, hence, in' the operation of the valve,
23, may be supplied with gas.
' fromthe' main 27 an By means of this construction, the one valve and the one branch pipe 31 will permit all four burners in the group to be operated until the range-top is sufficiently hot and then "amanipulation of the valve 38 will operate ;to cut off gas from two of those four burners but allow the other supply is usually maintained as long as any part of the range is in operation'this pilot burner will always be in readiness to ignite the gas turned on through either group of burners 23 or 24% Each end of the upper main 26 on a range is provided with a flange 50 (see Fig. 7) having'perforatlons 51 therein so that said flange may be coupled with a like flange on the main of another range and thus produce a continuous main where two, three or more ranges are coupledtogether in a battery. The main at the end of such a battery will have a plate attached to its flagge '50 whereby to efiectually seal that en v The 'lower horizontal main 27, extends from the vertical supply-main 25, across er burner compartment. 14 where a series of oven burners 53 are located.
The front wall 12 of the range is -pro-- vided with a lurality of openings 54 through which ti inserted so that the inner endsthereof may be inserted in suitable sockets-55 at the rear as shown in Fig. 11 of the drawing. The forward or outer ends 56 of the-burners are flared or of a bell shape and the openings 54, in the front plate 12 of the range are larger thansaid flared ends of the burners to permit ready manipulation of the latter e burners may readily belUU - a horizontal planejust in front of the lowwhen the same are being connected to or dis- I connected fromthe ni pics 57 that project through which gas is supplied.
To provide a proper support for the outer ends of these oven burners and also to effect a closure of the-large openings 54 in the front plate 12 of the range, I provide two. 1
horizontalplates 58 and 59' respectively of a novel construction. J
By reference 'to Figs. 1, 10, 11, 12 and 13 of the drawings it will be noted that these plates 58-59 have rabbeted horizontal edges 60, which lap=and interlock, and that at mtervals said edges are provided with se mental notches 61 which are beveled. When these plates are brought together the notches in the edge of the one plate will register with the notches in the edge of the other and the registered notches will together form circular openings with a beveled wall so as-to close about the flared end 56013 the burner and retain the latter in place.
The opposite ends of the plates 58 and 59 are outwardly flanged so as to project over i and seatclose against the vertical edge of from said upper the bracket plates 17 and screws 62, rigidly hold the plates in position.
The edges60 of the plates 58 and 59 arealso provided with seml-circular notches 63, so that the nipple 64 of a pilot burner may pass therethrough adjacent to or between two of the oven burners 56.
The nipples 57 of the oven burners and the nipple 64 of the pilot burner are .each connected to the lower horizontal main 27, and each of these nipples has its own control valve such as indicated at 65 in Fig. l.
The lower main 27, of one range like the upper one 26, is intended to be coupled to a like lower main on the next range in a.
battery of ranges, or be closed by a blank plate as desired.
From the foregoing explanation it will be understood that the control valves 33, 34: and 49 to the upper group of top burners are closely located at the center of the range wherethey are readily accessible to turn on or oil' as desired and that the gas to the two groups of top burners flows fromthe upper main into the branch pipes and to one or both passages 36 and 37 as desired.
It will also be understood that the supply of gas to the'lower oven burners is taken from the lower main directly to the burners themselves but is controlled by separate valves so that any one or more of said lower burners may be utilized at a time.
Having described my invention, I claim,v
1. In a gas range the combination with a plurality of top burners arranged in groups,
