Claims.

The present invention relates to improvements in boilers as used in steam, hot water and vapor heating systems, and has for its primary object the provision of a simple, compact and convenient construction of the water tube type wherein provision is made for ready access to the tubes in case repair or substitution thereof becomes necessary.

A further object is the provision of an arrangement capable of easy, economical manufacture and insuring lengthy, satisfactory life in use, as well as one which lends itself to ready variation as to size and capacity and which for ordinary use in homes will be small, compact and highly desirable.

The above and other objects of the present invention will more clearly appear in the course of the following detailed description of the best mode so far devised for carrying the invention into practical effect, and by reference to the accompanyng drawings, forming a part of this specification, and wherein Figure l is a side elevation, the adjacent side plate being removed to show the interior of the water transfer compartment.

Figure 2 is a vertical transverse sectional view taken substantially on line 2-2 of Figure 1.

Figure 3 is a Vertical longitudinal sectional view taken substantially` on line 3--3 of Figure 2.

kFigure' 4 is a horizontal sectional view taken 30 substantially on line 4 4 of Figure 3, and

Figure 5 is a partial side View looking at the opposite side with respect to Figure 1, and with the rear side plate broken away to show the interior of the water inlet and outlet compartments.

Referring now to these figures, the boiler as proposed by my invention is preferably of rectangular form and its main frame or casting seats in use upon a supporting base I0, which may support a suitable grate structure (not shown), if solid fuel is to be used and which has for this purpose a space I I to form an ash pit and a door I2 to this space and also for draft purposes.

The main frame or casing of the improved 4:3' boiler comprises a'top wall I3, front and rear walls I4 and I5 and side walls I6 and I 1, it being noted the side portions of the top, front and rear Walls extend appreciably beyond the side walls 1936, Serial No. 87,085

erably connected by stay bolts of a character to permit ready removal of these side plates whenever it becomes necessary or desirable to plug, repair or replace any of the water tubes as presently described. These side plates may be bolted to the main frame or casting around the edges thereof, or secured in any suitable manner either permanently or with ready removal in mind.

The space between the side walls I6 and II is occupied by a series of vertically spaced horizontal rows of transverse water tubes whose ends are suitably fixed in and open through the side walls I6 and Il and into the spaces between these side walls and the respective side plates I8 and I9. In the specific arrangement shown, it will be noted from Figure 3 in particular there is a vertical row ZI of water tubes at the rear of the lower portion or lire box 22 of the boiler, and above this re box is one horizontal row 23 of tubes below a horizontal baille wall 24 extending rearwardly from the front wall I4 to a point spaced from the rear wall I5. Above baille 24 are three rows 25 of tubes below a second horizontal baille wall 26 extending from the rear wall I5 to a point spaced from the front wall I4. Then, a series of horizontal rows 2l of tubes are arranged between the upper baille 25 and the top wall I3, and it is obvious the products of combustion in lire box 22 are forced to a circuitous path rearwardly of the lower baille 24 and forwardly of the upper baille 26 in their travel to the upper rear outlet 28 centrally of the upper portion of rear wall I5, and during this travel the heat products sweep through the tubes 23, 25 and 2l so as to provide for a very thorough, complete interchange of heat units. It is to .be understood, however, the above relation in numbers of tubes to the baille walls 24 and 26 may be varied to a considerable extent, and that in practice the outlet 28 receives one end of the smoke pipe 29.

Referring to Figures l and 2, it will be noted from the latter that the side space between side wall IS and side plate I8 is divided by a horizontal partition 3G outstanding from side wall I6, into an upper receiving chamber 3| with which feed or system return pipes 32 communicate, and a lower outlet chamber 33 with which outlet pipes 34 communicate, and it will be further noted that partition is about level with the upper baille wall 26 so that the return water through pipes 32 circulates through the water tubes 2l above said baille wall into the upper portion of the opposite side space.

From Figure 1, it will be seen that the space between side wall I1 and side plate I9 is divided by virtue of parallel front and rear vertical partitions 35 and 36 in spaced parallel relation to the adjacent side portions of the front and rear walls I4 and I5, and a horizontal partition 31 at the level of the opposite side partition 30, extending between the said vertical partitions 35 and 36, so that water flowing through tubes 21 from the receiving compartment 3| nds its way into a chamber 38 between partitions 35 and 36 above partition 31. However, partitions 35 and 36 terminate at their upper and lower ends in substantially spaced relation to the top and bottom of their respective side space and consequently water in chamber 38 will overflow the upper ends of said vertical partitions and drop through the channels 39 between partitions 35 and 36 and the front walls I4 and I5 and thus find its way into the lower chamber 40, that is, the space below horizontal partition 31 for passage through the tubes 2I, 23 and 25 to outlet compartment 33 and nally to the system through outlet pipes 34.

In the above operation the return water is pre- 5 liminarily heated at a point where it effectively absorbs the'heat units from the products of combustion just prior to the outlet of these products through the smoke pipe, and subsequently passes through and above the combustion space in a condition to readily absorb the greater portion of the heat units at this point.

It is obvious that for the above purposes, oil, gas or solid fuel may be employed and that the boiler may be provided with various indicators and guides such as an altitude gauge 4I, steam gauge 42, thermometer 43 and relief valve 44. It is also preferable that an air vent pipe 45 extend, as best seen in Figure 2, from the upper portion of the space between side wall I1 and side plate I9. This vent pipe may be arranged to outlet in any manner suitable to relief of the apparatus from the danger of air locks.

i It is also obvious various other features such as clean-out valves 46 and the like may be employed r without affecting the rugged strength, ready accessibility, and general eiiciency of the improved construction above outlined. A clean-out door 41 may be arranged in the rear wall as seen in Figures 2 and 4.

What is claimed is:

l. A steam and water boiler consisting of a rectangular body having its top, bottom, front and rear walls extending uniformly beyond the side walls thereof, side plates xed to the extending portions of the first-mentioned walls to form side spaces between said plates and the side walls, vertical partitions partially along one side wall in the respective side space forming vertical channels between the same and the front and rear walls, a horizontal partition dividing the space between said vertical partitions, a horizontal partition dividing the other side space into an upper receiving compartment and a lower outlet compartment, outlet pipes leading from the latter compartment, return pipes leading from the receiving compartment, a series of water tubes extending between the side walls and opening at their ends into the said side spaces above the horizontal partitions, and a series of water tubes extending between the side walls and opening at their ends between said side spaces below the horizontal partitions, the said channels forming circulating waterways between those portions of the respective side space above and below the horizontal partition thereof.
