L. F. DOEN VALVE July 26, 1932.

Original Filed July 20, 1926 Reissued July 2 6, 1932 UNITED STATES PATENT OFFICE- LOEAN I. DOEN, OF CLEVELAND, OHIO, ASSIGNOR T0-THE CLEVELAND HEATER COM- IPAINY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO '1 Q VALVE Original N0. 1,759,891, dated May This invention relates to gas appliances and in particular a fuel control accessory and valve for use in connection therewith.

The object of this invention is to provide an improved gas valve and spud holder with means forming a part of the valve for connecting the Bunsen tube of a gas burner to the gas supply line so that the gas conduit may be readily separated and closed at the valve for removal of the burner and other purposes.

These and other objects will appear from the following detailed description and appended claims.

In the accompanying drawings forming a art of this specification are illustrated emodiments of the features of this invention in which:

Figure 1 is a front elevational view partly in section of a water heater illustrating a gas appliance which is adapted for use of my improved valve.

Figure 2 is a front elevational view of the gas and air mixing tube of the burner shown in Fi 1.

Re erring to Figure 1, the numeral 1 designates the casing of a heater having a heating coil 2 adapted to be connected at its extremities in the usual manner to the top and bottom of a boiler, so that there is a circulation of water through the coil and boiler when the burner is in operation. The burner 3 is mounted on a Bunsen or mixing tube 4 by means of a threaded joint.

The means comprising projecting" lugs 5 and a collar 6 forming an integral part of the Bunsen tube cooperate with helical projections or ledges 7 in a central aperture 9 of the base 8 to securely and detachably hold the Bunsen tube in position in the heater base. A pair of diametrically opposed vertical slots (not shown) are provided in the base for reception of the lugs 5 to permit the insertion and removal of the Bunsen tube in the assembled heater base.

The heater base 8 is made in two pieces comprising the fixed element shown, and a removable element (not shown) that is adapted to engage the lugs 22 and fill in the cut-out portion of the base providing a base that permits the ready installation or re- 'moval and replacement of the burner assemcOmbined union moval of the assembled burner'and mixing tube. The base itself forms the subject mat 27, 1980, Serial No. 123,690,.fi1ed July 20, 1926. Application fol-reissue filed January 15, 1932. Serial No. 587,079.

The subject matter of this invention is confined to the gas valve certain modifications of which are shown and specifically claimed in my copending applications 184,141 and 184,142.

The above-mentioned applications have resulted, respectively, in the following patents: Patent No. 1,830,866, issued November 10, 1931, Patent No. 1,843,936, issued February 9, 1932, Patent No. 1,759,892, issued May 27, .1930, and Patent No. 1,759,893, issued May 27, 1930.

As a further means of facilitating the rei bly, a combined union and spud holder is screwed into the lower end of the Bunsen .tube. The lower endof the. union carries cook 29 to control theflow of gas from a main fuel feed line to the burner. The flanged element 31 of the union is held from turning in the Bunsen tube by a lockuut 33 which also serves to lock the air shutter M in position. A gas spud 30 is removably secured within the flanged element 31 of the andspud holder. The nut- 32 serves to hold the union together, and upon loosening it the Bunsen tube is quiclily disconnected from the gas line permitting the removal of the Bunsen tube with its associated burner from the heater base in the manner described.

Furthermore, it is to be understood that the a gas particular forms of apparatus shown and debody externally threaded at one end forming 21 a g I 18,640

the female portion of the union connection, a combined union and spud holder forming the male portion of the union connection adapted to be detachably secured to the externally threaded portion of said valve body, and agasfspud carried in said spud holder.
