GAS BURNER.

' Application filed April 2a, 1921, Serial No. 463,772. Renewed October a, 1923.

' To all whom it may opncern:

Be it known that 1, JAMES H. REINHARDT,

a citizen of the United States, and resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Gas Burners, of which the following is a specification.

My invention relates to improvements in gas burners of the blue-frame or Bunsen variety, and has particular reference to gas burners adapted for stoves, ranges and hotplates.

One object of my invention is to provide a gas burner having a plurality of lndependent burner elements in a unitary structure with a key adapted to direct gas to one of said elements, or to several of said elements simultaneously, whereby the amount of flame utilized at a given time may be controlled at will.

Another object of my invention is to provide the gas burner with a single valve having outlets to supply gas to the separate channels of the several elements before mentioned with means to regulate the flow of gas to each such element independentlyto produce the desired flame at such element.

My invention comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein Fig. 1 is a plan view of a gas burner embodying my invention; Fig. 2 is a section on the line 2, 2 of Fig. 1; Fig. 3 is a section on the line 3, 3 in Fig. 1; Fig. 4 is a section on the line 4, 4 in Fig. 2; Fig. 5 is a section on the line 5, 5 in Fig. 4; Fig. 6 is a plan View of the middle member; Fig. 7 is an inverted plan view of the middle member; Fig. 8 is a plan view of the upper member 1; Fig. 9 is a detail of the gas valve; Fig. 10 is a section on line 10, 10 of Fig. 9, and Fig. 11 is sectional detail end view.

Similar numerals of reference indicate corresponding parts in the several views.

The numerals 1, 2 and 3 respectively indicate lower, middle and upper members of my improved burner, which may be secured together in any desired manner, as by bolt a. Between the members concentric channels for gas and air mixture are provided with parallel channels leading thereto from the gas and air supplies. In the example illustrated member 2 is provided on opposite sides with walls that are spaced apart against which the members 1 and 3 fit to provide said channels. Member 2 is shown provided with a central curved wall 4 on one side from which extend spaced parallel walls 5, 6, providing a channel or chamber 7 and mixture conducting channel 8. Lead ing from wall 6 around wall 4 and spaced.

therefrom is an annular wall 9 providing a channel 10 concentric with channel or chamber 7, and from wall 9 extends a wall 11 parallel with and spaced from wall 5, providing channel 12 parallel to channel 8 and communicating with channel 10. On the opposite side of member 2 is an annular wall 13 providing chamber 13*. Wall 13 connects with wall 14 parallel with and spaced from Wall 15 providing channel 16. Wall 15 leads from wall 15 annularly around and spaced from wall 13 providing annular channel 17 concentric with chamber 13. The wall 18 extends parallel with and spaced from wall 14 and connects with walls 13 and 15 providing channel 19 as a continuation of chamber 13. The member 3 has an annular wall 3 surrounding wall 9 and within wall 6 providing channels 10 and 10". Member 1 closes the open channels on the lower side of member 2 and member 3 closes the channels on the upper side of member 2 when said parts are assembled as shown in Figs. 2 and 3. By preference the walls and opposing members will be cemented together. Member 2 is provided with holes 20 providing communication between chamber 13 and channel 10* and holes 21 providing communication between chan' nels 17 and 10 for the flow of mixture from chamber, 13*, and channel 17 to channels 10 and 10 respectively. Member 3 is provided with holes 22, which holes are shown annularly disposed over the channels. Member 2, near one end, is shown provided with an enlargement or block-like portion 23, preferably cast integral with said member, provided with a bore 24 to receive a valve 25 to control the flow of gas to the channels. A nipple 26 on enlargement 23 communicates with bore 24 for inlet of gas. The outer ends of walls 5, and 14, as well as the corresponding parallel channels, terminate adjacent to the inner wall of enlargement 23, sothat the channels 8, 12, 16 and 19 will receive gas from passages 28 in said enlargement. aid passages communicate with bore 24 (Fig. 6). The end portions 6, 11", 15 and 18" of walls 6, 11, 15 and 18 respectively extend around and are spaced from enlargement 23, the ends of said walls being spaced apart for the entrance of air to the channels, providing continuations of the parallel channels. Enlargement 23 has passages 28, providing communication for gas from bore 24 to channels 8, 12, 16 and 19.

The narrow end portion of member 3 rests over enlargement 23 and the latter is provided with a hole 29 through which the valve 25 projects in position to be operated, the valve being rotatively retained in bore 24 by a screw 30. Member 3 has an opening 31 receiving enlargement 23. The gas passages 28 are spaced apart and are on appropriate levels to deliver gas to the respective channels 8, 12, 1'6 and 19. The valve 25 has an interior bore 25 (Fig. 5) communicating with a side port 32 that is adapted to register with nipple 26 to admit gas to the valve, a groove 32 in the outer surface of the valve extending around the same for a suitable distance to receive gas from nipple 26 when the valve is in different operative positions. Valve 25 has ports 25 on diflerent levels communicating with.

bore 25 to deliver gas to channels 8, 12, 16 and 19 respectively. Grooves 25 on the valve lead from said ports 25 for difl'erent distances around the valve to supply gas to channels 8, 12, 16 and 19 from nipple 26 in diflerent operative positions of the valve. The ports and grooves of the valve are so arranged that when the valve is in one position, (Fig. 1), all the gas passages 28, will be closed and no gas will flow to the channels. A projection 33 on the valvemay engage a stop 34 on member 3 in the last named position of the valve. When the valve is placed with projection 33 at the position b in Fig. 1 gas Wlll flow through a passage 28 to channel 8 to mix with air therein, the mixture flowing from channel 8 to channel 7 and thence through the corresponding holes 22 to be burned, to serve as a small flame, such as the so-called simmerer. When valve-25 is placed with projection 33 at the point 0, Fig. 1, a passage 28 will supply gas to channel 12 for channel 10, the mixture formed in channel 12 flowing from channel 10 through the correspondin holes 22 while the gas continues to flow rom the simmerer holes, thereby increasing the effective flames. When valve 25 is placed with projection 33 at the point (i, Fig. 1, mixture will continue to flow from channels 7 and 10, and gas will be supplied 1,ess,21a

supplied to passage 16 for channel 1.7

through its holes 22 to further increase the efiective flame. Corresponding reduction of flame may be effected by reversing the position of valve 25. By the construction described the advantage is attained of having full use of proper mixture for any volume of flame desired, within the limits designed, and the flame is at all times beneath a pot on the burner, so that a small flame may be instantly increased or decreased beneath a pot without requiring the latter to be moved from one burner to another to increase the heat applied. Projection 33 may encounter a stop 35 on member 3 when valve 23 presents all its ports in register with passages 28.

Since the volume of gas for each channel should be in proportion to the dimensions of the latter I provide means to independently regulate the flow of gas through passages 28, for which purpose I provide screws 36, operative in threaded holes in enlargement 23, that communicate with said passages. By adjusting said screws respecting said passages the flow of gas for mixing with air for the corresponding channel may be regulated to provide the desired character of flame for each section of the burner. The member 3 has holes 37 receivin said screws rendering the latter accessib e for ad'ustment.

y improvements will be found of advantage in ranges, hot-plates and the like,

enabling the user to utilize one or more of the burner sections, as desired, by simply rotating the single valve 25' to the desired position while obtaining the benefit of a proper mixture of gas and air for each burner section desired. Changes may be made in the details of construction set forth, within the scope of the appended claims, without departing from the spirit of my invention.

Having now described my invention what I claim is:

1. A gas burner comprising spaced members having fuel channels therebetween and fuel exit holes communicating with said channels, one of said .members having an enlargement provided with a valve opening and passages providing communication between said opening and said channels, a

valve in said opening having a bore and lower sides opposing said upper and lower said channels, and a valve in said enlargemembers respectively PIOVldiIlg channels ment having ports to respectively supply therebetween, the middle and upper memgas to said passages.
