1 Claim.

My invention relates to multitubular boilers of the water tube type and has as one of theprincipal objects thereof the provision of a boiler wherein the tubes are so arranged as to quickly heat the water circulating therethrough thus maximizing the heating eificiency of the boiler as well as effecting an economy in fuel.

Another object of my invention is to provide a boiler of the character described which is simple in construction, durable in use, eificient in operation and economical in manufacture,

Other objects and advantages will be apparent from the following description, appended claims and annexed drawing. 15 Referring to the drawing wherein like refer ence characters designate like parts throughout the several views:

Figure 1 is a longitudinal sectional view of my invention and taken on the line l! of Figure 2. 20 Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

In practicing my invention I provide a boiler 5 comprising upper and lower sections 6 and 1 respectively, said upper section constituting a Water jacket fashioned with spaced inner and outer side walls 8 and 9 respectively and inner and outer top walls Ill and II respectively.

The lower ends of the side walls 8 and 9 are welded to a plate [2 fashioned with a centrally 30 disposed aperture in which is positioned a fire grate l3 supported by said plate and adapted to receive thereon fuel for operating the boiler in a manner hereinafter setforth. The lower section I constitutes an ash pit, access being had 35 thereto by means of a hinged door 14 mounted on the front of the boiler. Adjacent the upper and lower ends thereof, the water jacket is fashioned with shells l5 extending through the inner and outer walls 8 and 9 on the front of the boiler and constituting clean out and fuel feed openings l6 and I! respectively. Said openings l6 and I! are closed by doors I8.

The inner and outer walls of both the side and top of the water jacket define a water chamber I9 therein and the upper end of said chamber communicates with an outlet connection 20 adapted for connection to the feed pipe (not shown) of a heating system. The lower end of the water chamber I9 has communication with connectionsii adapted to be connected to return pipes of said system. A water supply pipe 22 is connected to the lower end of the jacket whereby to supply said jacket with water as desired.

The lower section of the water jacket defines a fire box in which the fuel on the grate is coning tubes 25 welded to the inner wall of the jacket and having communication at their respective ends with the water compartment. Said tubes are arranged in diagonal relation and in alternate directional planes. The upper section of the tube chamber has extending therethrough a plurality of upper and lower tubes 26 and 21 respectively which converge towards one side of said boiler and interposing said upper and lower tubes 26 and 21 and the lower diagonally arranged tubes 25 are spaced baflle plates 28 having alternate ends spaced from the front and rear of the jacket. Subjacent the inner wall H], the rear of the jacket has extending therethrough a smoke pipe connection having communication with the upper end of the tube chamber and is adapted to be connected toa chimney or the like whereby smoke is carried from the boiler.

Due to the angular positions of the tubes within the boiler, a greater quantity of water will be subjected to the heat from the fire box than in instances where said tubes are arranged in horizontal positions within a boiler having a similar size tube compartment and fire box, thereby greatly reducing the time required for heating the water in the tubes and at the same time effecting an economy in fuel. The baffle plates serve to circulate the heated air about the tubes and to ellect a concentration of said heated air subjacent the top of the water jacket whereby the water therein is maintained at a high temperature for circulation into the feed pipe of the system.

Also, return water from the system is introduced into the water jacket at a point surrounding the fire box whereby said water is heated considerably before being circulated through the tubes.

It is obvious that the invention is not confined I to the herein described use therefor as it may be utilized for any purpose to which it is adaptations, I said upper section constituting a water jacket formed with a tube compartment and a fire box defined by the lower end of said jacket and about which water is adapted to circulate, a plurality of diagonally arranged tubes mounted in the lower portion of said compartment above side of said 'jacket and communicating with the said first mentioned tubes.

latter, and heme plates mounted in said compartment and interposing said first mentioned tubes and said second mentioned tubes andthe tubes of each series whereby to circulate heat from said fire box about said tubes'for effecting the heating of water circulating upwardly therethrough, said first mentioned'tubes being disposed in alternate directional planes for maximizing the heating of water circulating through SCOTT "Ll KE'LLING.
