Original application med'riay 28, 1913,

To all whom it may concern:

Be it known that I, ROBERT T. PARISEN, a citizen of the United States, and resident of Knoxville, in the. county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Stand- Boiler Burner-Chambers, of which the following is a specification.

1 This is a division of my application Serial No. 770,318, filed May 28, 1913. The primary object is to provide a novel burner chamber with referenceto the special requirements for stand boiler use, the chamber being of such form as to readily adapt it for union with the boiler, and when in place corresponding to the contour of the boiler and in position to be conveniently accessible even though smaller in cross section than the boiler to which it is applied.

A further purpose is to adapt the improved chamber to a gas burner located therein, with an opening in the chamber bottom arranged to receive the fuel inlet of the burner, together with improved means for connecting the fuel supply tube with the burner inlet. 1 I

In the accompanying drawings, Figure 1 is a view partly in elevation and partly in vertical section of a stand boiler having the improved burner chamber applied thereto. Figs. 2 and 3 are sectional plans, taken on lines 22 and 33, respectively 1 Of Fig. 1. Fig. 1 is a sectional elevation ofthe lower portion of the burner chamber, taken on line l4: of Fig. 3. Fig. 5 is a detail perspective of the burner chamber.

Referring to the drawings, 2 designates the wall-forming shell of a stand boiler which, in the present adaptation, has its lower edge reinforced by the hoop-like rim spot-welded thereto at 5. Depending from the rim are the boiler supporting legs 6, the upper extremities of the legs being flanged at 7 to fit the inner face of the rim to which each is secured by,a screw or bolt 8. A boiler of preferred form for use in conjunction with the improved burner chamber is provided with the internal cylindrical shell 9 which is open through the boiler bottom 1, the shell-receiving opening in the bottom being flanged downwardly at 4. A vent pipe 10 extends from the upper end of shell 9 to the exterior of the boiler, preferably through the crown thereof. As the Specification of Letters Patent.

191 1. Serial No. 812,011.

burner chamber, presently to be described, is n communlcatlon with the bottom of shell 9, all the heat and products emanating therefrom pass upwardly through the shell and are conducted off through pipe 10. The

shell and pipe being surrounded by the water contained in the boiler, much of the heat that would otherwise escape and be wasted is radiated to and absorbed by' the water. 1

When the boiler is to embody or include a coil heater, shell 9 constitutes a suitable come partment for coil 12, with the lower ext-reniprovide a slip joint connection with the flange at of the boiler bottom, thereby constituting the chamber a downward continuation of shell 9. Beneath circular part 21 the chamber is enlarged at one side at 22 toprovide a frame for door 23 for the open face of the enlargement, the latter being curved complementary with rim 5, and with lugs 24' projecting upwardly from the door frame over the inner faceof the rim and to which they are secured by screws or rivets 25, thereby supporting chamber 20 in position to have its door-closed enlargement form a downward continuation of boiler shell 2. The annular chamber part 21 may be slotted at 26 to embrace bottom extension 13 of the coil.

A ring-like gas burner 27 is adaptedt'o be entered in the chamber through door 23, with thecentral fuel inlet 28 thereof extending through bottom opening 29 of the chamber. The air inlet portion 30 of said tered in offsets 29 of bottom opening 29. The burner may be secured by set screw 83 in lug 33 projecting upwardly from the chamber bottom. A fuel tube 34 is held in place in the burner inlet 28 by set screws 35 entered through flanges 32 beneath the chamber bottom, the fuel supply extending from any suitable source.

Chamber 20, in addition to inclosing the burner operates to catch and retain condensate dripping from shell 9 or from coil 12 until it evaporates, a flange 40 around bottom openings 29 and 30 and ledge-like flange 41 at the door opening preventing the water from running out. The drippings are thus confined in relatively close proximity to the burner and evaporate before they can overflow. In the construction shown, bottom flange 4L0 serves to support the burner.

I claim 1. The combination of a stand boiler, a burner chamber beneath and smaller in cross section than the boiler, the chamber enlarged at one side toward the plane of the vertical side wall of the boiler, and a door-closed opening in said enlargement.

2. The combination of a stand boiler, a burner chamber beneath and smaller in cross-section than the boiler, the chamber enlarged at one side with the enlargement extending to and forming a downward continuation of the upright wall of the boiler, and a door-closed opening in the enlargement.

3. The combination of a stand boiler, a burner chamber beneath and smaller in cross-section than the boiler and secured thereto, the chamber enlarged at one side to conform to the contour of the boiler, and a door-closed opening in said enlargement.

a. The combination of a stand boiler, a burner chamber beneath and smaller in cross-section than the boiler and formed with a side enlargement, and a door-closed opening in the enlargement.

5. The combination of a stand boiler, a burner chamber beneath and smaller in cross-section than the boiler and formed with a side enlargement, the chamber and its enlargement being located wholly between the planes of the upright walls of the boiler, and a door-closed opening in the chamber enlargement.

6. The combination of a stand boiler, a closed-bottom burner chamber beneath the boiler, the chamber bottom adapted to confine condensate dripping thereinto, and a gas burner within the chamber.

7. The combination of a stand boiler, a closed-bottom burner chamber beneath the boiler, the chamber provided with a door opening above its bottom and the bottom formed with an upwardly flanged opening whereby th chamber is adapted to confine condensate dripping thereinto, and a gas burner within the chamber and having a fuel connection through the bottom openin 8. The combination of a stand boiler having a bottom rim, the burner chamber beneath and smaller in cross-section than the boiler and enlarged at one side to form a door frame, and means for securing the frame enlargement to the boiler rim.

9. The combination of astand boiler having a bottom rim, a burner chamber beneath and smaller in cross-section than the boiler, the chamber enlarged at one side, and lugs projecting from the enlargement and secured to said rim for sustaining the chamber.

10. An inclosed burner chamber for a stand boiler having an air admitting opening through its bottom, a gas burner within the chamber and formed with a vertical air passage which communicates with said bottom opening, and a gas inlet for the burner entered through a wall of the chamber.

11. An inclosed burner chamber for a stand boiler having an opening through its bottom, a gas burner supported by the chamber bottom and formed with a depending fuel inlet extending through said bottom opening, and a fuel feeding tube connecting with the burner inlet and secured thereto at the exterior of the chamber bottom.

12-. A burner chamber for a stand boiler formed with a bottom opening and with lateral ofisets in the opening, a burner within the chamber and having a depending gas inlet extending through said bottom opening with the inlet flanged laterally to fit the opening ofisets, set screws entered through the flanges, and a fuel tube entered in the burner inlet and secured by said screws.

In testimony whereof, I aflix my signature in presence of two witnesses.

ROBERT T. PARISEN.
