and Edmund J. Te Pas as joint inventors and relates to improvements in. the .base and burner construction" offiuid fuel fired. Water heaters. v l

It is customary in water heaters of the usual type in which atank of water is heated by the flame from a gas burner positioned below water circulation elements in communication with thetank, to-mount theburner upon a Bunsen or mixing. tube by either a ground or a threaded joint. j v j Then a ground joint is used; the end of the Bunsen tube-isfinished smooth and slightly taperedand adapted to snugly fit intoa bored out cylindrical extension of the burner. This type of oint is open to the obj ection. that upon removal and replacement of the burner gas-tight fit may notbe achieved on account of dirt or other foreign material lodging be tween the contacting portions of the Bunsen tube and burner. s v i T i v In order to overcome this objection and still retain advantagesot the ground joint, such as ease in removal and replacement ofthe burner for cleaningetc. heaters have been made in which the Bunsen tube and burner are provided with a threaded joint to insure at all times a gastight connection at this point.

Experience hasshown that after a time the n threadedjoint becomes rusted and it is in 1- possible to remove the burner from theBunsen tube Without the use of tools which cannot be manipulated in the limited space in the heater casing. In this caseithe' heater base i which carries the Bunsen tube and burner is removed from its casing and the burner is then'removed from the Bunsen tube.

One of the obj ects of this invention istol provide ,a heater base in which the assembled burner and Bunsen tube can be quickly and easily installed or removed'without disturbing the attachment of the base to the heater casing. v v

Another object of this invention is to pro- 'vide an improved means-of connecting the i Bunsen tube to the gasfeed line. These and 1-926, Serial 1%.. 123,690; .Divided and this application filed April 21,

other objectswill appear from'the following detailed description and appended-claims. f inthe accompanying drawings-forminga part of this specification are illustrated em-r bodiments of the features of this invention 1n which; Fig. 1 is an elevation partlygin'sectron of awater heater wlth asection of its base removed and embodying features ofthis invention. -Fig. 2 is an elevation of the Bunsen or mixing tube. Fig. 3 is a perspectl'ive viewof the heater base member used in Referring to Fig. 1; the numeral 1, desig-,

nates the casing of aheater having a heating coil 2 adapted to be connected at its extremities in the usualrnanner to the topandbot: tom of boiler, so that there is a circulation of water through the coil andboilerwhen the. burner is in operation. The burner 3 is mounted on a Bunsen or,mixing tube by' means of a threaded joint.

,Means comprising projecting lugs 5 and-.a

collar 6 forming an integral part of the Buni sen tube cooperating with helical projections orle'dges in a central aperture Siof the base 8 to securely and; detachably hold the Bunsen tube-in position in the heater base. A pair of diametrically. opposed vertical slots 10 for reception of the lugs 5 permit the insera tion and removal of the Bunsen tube in the assembled heater base. o

The heaterb'ase 8 is madeiin cessed portion at 1 4 to form a drip collection andjevaporation pan forcondensates from the heating coils. "A raised seat 15 having positioning lugs 16is adapted to be detachably held in'contact with the heater casing by holes.17

rods or bolts passing through the formed in the base.

Secondar combustion-sue ortin air in b lets 18are provided between the drip pan and the skirted edge of the base. [In orderto.

permit the insertion or removal of the burner andBunsen tube in the'ir assembled state, tl

v e re novable seg nent'12 fits. in avertically walled spacefofsimilaroutline in the base member 11. lhe removable segment' lQ has two/pieces. comprising. the hxed element .11 and there vertical walls 19 and recessed portion 14 constituting a drip collection and evaporation P The removable section 12 is provided with overhanging edges 20 adapted to extend over the vertical walls 21 of the fixed member 11 of the heater base. A pair of supporting lugs 22 integrally formed on the fixed member 11 are adapted to fit under the raised seat to support and position the outer edge of the removable section 12. are provided with raised portions 23 to support the inner end of the removable segment 12 of the base. The side walls 19 and overhanging edges terminate at the inner end of the removable segment 12 in a pair of in clined faces or walls 28 which lie closely adjacent to and in parallel relation with the in clined faces 27 of the fixed portion of the base when the removable section 12 is in position in the fixed section 11.

It is apparent from the foregoing, taken in connection with Figure 3 that the removable section 12 can be easily and readily removed and replaced without the use of tools.

As a further means of facilitating the removal and replacement of the burner assembly, a combined union and spud holder 31 is screwed into the lower end of the Bunsen tube 4. The lower end of this union carries a gas cook 29 to control the flow of gas from a main fuel feed line to the burner. The male element of the union 31 is held from turning in the Bunsen tube by a locknut 33 t. which also serves to look the air shutter 34 in position. The union nut 32 serves to hold the union together, and upon loosening it the Bunsen tube may be readily 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 particular forms of apparatus shown and described, and the particular procedure set a forth, are presented for purposes of explanation and illustration and that the various modifications of said apparatus and proce dure can be made without departing from my invention as defined in the appended claims:

I claim:

1. A base unit and burner support for a heater casing comprising a fixed element having a segmental cut-out portion adapted to be detachably secured to the heater casing, a removable segment adapted for reception in the cut-out portion of said fixed element and defining an aperture therewith, horizontally extending portions carried by said segment adapted to engage said fixed element at a point closely adjacent to the margin of said aperture, means provided by said fixed element for supporting the outer edge of said segment, and a burner carrying tube adapted to be supported in the aperture between said segment and said fixed element, said The vertical walls 21' tube having a portion engageable with said segment for rigidly holding said segment in position in said fixed element.

2. A base unit and burner support for a heater casing, comprising a fixed element having a segmental cut-out portion adapted to be detachably secured to the heater casing, a removable segment adapted for reception in the cut-out portion of said fixed element and defining an aperture therewith, overhanging edges carried by said segment adapted to rest on said fixed element adjacent the center thereof, horizontally projecting lugs formed on said fixed element providing a support for the outer edge of said segment, and a burner carrying tube adapted to be supported in the aperture between said 88g". ment and said'fixed element, said tube having a lug arranged to engage said segment at a point between the innermost and outermost edges thereof whereby said segment is rigidly and removably secured in said fixed element.

3. In a gas fired water heater, a heater casing, a drip pan secured to the bottom thereof having a segmental cut-out portion, a removable recessed segment adapted to fit in the cut-out portion of said pan and to form a central aperture therewith, overhanging edges formed on said segment adapted to extend over the marginal edges of'the cutout portion of said pan and to rest on said pan at points adjacent the center thereof, means provided by said pan for supporting the outer edge of said segment, a burner carrying tube adapted to be received and-supported in the aperture between said pan and segment, and a lug formed on said tube arranged to engage the inner end of said segment at a point intermediate the sides there-- of whereby the segment is securely held in place in said drip pan.
