WITNESSES INVENTR turn sans 'PTE ROBERT T. BARISEN, OF KNOXVILLE, PENNSYLVANIA, ASSIGNOR T LAWSON MANU- FACTUBING- COMPANY, OF HOMESTEAD, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

STAND-BOILER.

Application filed May 28, 1913.

To @ZZ whom it may concern Be it known that l, 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-Boilers, of which the following is a specification.

rEhe primary object of this invention is to provide a stand boiler of improved construction having a water heating coil located in a shell which is positioned within but closed to the boiler, whereby a relatively large area of heat-radiating surface is eX- posed to the water so that practically all of the heat is utilized.

A further purpose is to provide a burner and combined burner-inclosing chamber andl drip pan of novel construction, together with improved means for securing the chamber as well as the boiler-supporting legs to the vlower portion of the boiler.

In the accompanying' drawings, Figure 1 is a front elevation of the improved boiler, and Fig. Q is a vertical longitudinal section of the same. Figs. 3 and l are sectional plan views taken on lines 3dS and 4wd, respecf tively, of Fig. 1. Fig. 5 is a view of the burner-inclosing chamber detached from the boiler. Fig. 6 is a sectional plan of the burner chamber taken on line G-G of Fig. 2. Fig. 7 is a vertical section of the burner and burner chamber taken on line 7 7 of Fig. G.

Referring to the drawings, 2 designates a vertical shell of a cylindrical stand boiler of which 8 is the crown and 4 the bottom. The lower extremity of the shell is reinforced by the depending hoop-like rim 5, spot welded thereto at 5, and depending from the rim are legs 6, the upper extremities of thelcgs being flanged at 7 to fit the inner face of the rim to which each is secured by a screw or bolt 8.

Within and closed to boiler 2 and open through the bottom thereof is cylindrical shell 9, and extending from the top thereof through crown 3 is vent pipe 10 which projects slightlv above the crown with opposite sides of the projecting portion slotted at 11. lt will be understood that shell 9 and pipe 10 are sealed to the boiler interior and being surrounded by the water being heated a large area of heat radiating surface is ex- Specifcation of Letters Patent.

posed to the water in addition to the water heating coil presently to be described, thereby increasing the etliciency of the heating means.

Located within and depending` from shell 9 is water heating coil 12 with the lower extremity thereof extended laterally at 13 and connected to bottom l by coupling 111. A drain 15 may be extended from coupling 141, as shown. The upper extremity of the coil is extended upwardly through vent 10, as indicated at 16, and is bent laterally through one of slots 11 and connected by coupling 17 with crown 3, and this coupling may be utilized as a connection for the hot water service pipe 18. Cold water inlet may be connected to the crown at the opposite side vent 10, in fact the crown openings may be used interchangeably for the hot and cold water connections.

Flue pipe 10 has a slip joint connection with the slotted extremity of vent pipe 10 but is held by pipe 16 from fully covering slots 11, and the air admitted through the uncovered portions of the latter operates to check the draft upwardly through pipe 10.

rlhe lower portion of the coil is inclosed bv the burner chamber 20 having the open annular top portion 21 which connects with and forms a downward continuation of shells 9. Beneath rim 21 the chamber is enlarged at one side at 22 to provide a frame for door 23, the door enlargement being curved complementary with rim Project ing upwardly from the door enlargement are lugs 211 which engage the inner face of rim 5 with screws or rivets 25 extending through the rim and lugs, thereby supporting the chamber 20 in position to form a. down ward continuation of shell 9. Annular part 21 of the burner chamber is slotted at 2G to embrace coil extension 13.

The ring-like gas burner 27 is adapted to be entered in the chamber through door 23 with the gas inlet tube 28 thereof extending through opening Q9 in the bottom of chamber 20. The air inlet portion 8O of said opening is in line with vertical air passage 31 through burner 27, thereby supplying air in ample amount vfor combustion, the supply beingsupplemented by air admitted through openings in the wall of the chamber, also through openings 23 in the door.

Burner tube 2S is flanged on opposite sides at82 with the flanges entered in offsets 29 of opening 29, and the burner is secured by set Screw 33 in lug 33 projecting from the chamber bottom. A mixer tube Sais held in place in gas inlet 28 by set screws carried by flanges 32, with gas supply pipe 36 extending to the mixer from gas regulating valve 37 having its thermostatic extension 38 fitted in bo-iler 2 with the valve controlling the flow of gas to the burner. The thermostatic Valve may be of usual or any preferred construction.

Chamber 22, in addition to inclosing the burner, operates as a drip pan to catch and retain the condensate from the coil until it evaporates, flange 40 around

bottom openings

29 and 30 and ledge-like flange ll at the door opening preventing the water from running out. Vith the chamber beneath and in line with the coil the drippings are caught andk confined in relatively close proximity to the burner and evaporate before there can be any overflow. Flange l0 serves to support the burner, as shown.

lVater heating apparatus construction as herein shown and described is simple, durable and highly efficient. The parts thereof are easily accessible and may be readily assembled. The coil connections with the boiler are so arranged and located that they may be conveniently disconnected for renewing or repairing the coil.
