WATER-BOILER.

Specification of Letters Patent.

Patented Feb. 7, 19 11.

Application filed June 10, 1910. Serial No. 566,232.

T 0 all whom it may concern:

Be it known that I, lVInrano H. BU'roi-inn, a citizen of the United States of America, residing at Burwell, in the county of Garfield and State of Nebraska, have invented new and useful Improvements in Water- Boilers, of which the following is a specification.

This invention relates to water boilers and particularly to one designed for attachment toa stove pipe, the object being to utilize the heat for thoroughly heating the walls of the boiler suilicientl y on the discharge of the waste heat products.

Another object of the invention is to provide a boiler of this type wherein the bottom is of substantially frusto-conical form presenting a concavity which when the boiler is operatively positioned on the stove pipe will be located immediately over the stove and positioned to receive the best bcnclit of the heat.

Another object of the invention is to provide a boiler having a substantially funnelshaped top facilitating the filling of the boiler with. water.

In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views :Figure 1 is a detail vertical section through my improved boiler showing it applied to a stove pipe. Fig. 2 is a detail. top plan thereof showing the stove pipe in section. Fig. is a detail vertical section through a portion of the boiler showing a slightly modified form of my invention. Fig. 4 is a horizontal section showing a still further modified form.

My improved boiler consists of a casing 1 and 2, the said casing being apertured centrally for receiving the stove pipe A. The walls 1 of the casing have their ends extended beyond the top and bottom portions 3 and 4, and as illustrated, such portions carry clamping screws or similar equivalent well known devices for engaging the stove pipe to hold the boiler operatively positioned thereon. The bottom l of the boiler is of frusto-conical form presenting a relatively broad or large concavity 5 which when the boiler is operatively associated on the pipe will bedisposed at such point with respect to the stove to best utilize the full value of 1 suitable draw-off click 7.

' the wasteheat, the said concavity forming a. collector for the heat and the walls of the said bottom by being arranged, as shown, form a contracted lower portion 6 in the chamber, thus subjecting the water at this I point of the boiler to a great amount of heat. At the bottom the boiler is rovided with a 'I he top 3 of the boiler is formed substantially throughout to provide an annular concavity 8 which opens directly into the boiler, as illustrated. The construction of the boiler is such that its top is of substantially funnel form facilitating filling the boiler with water as is obvious. The opening in the bottom of the top 3 is closed by a suitable removable plug 9. i In the modified form of my invention shown in Fig. 3, the opening 10 in the top 3 3 is closed by a spring-controlled valve 11. The top supports a spider 12 throu h which the guide stem 13 extends, a relative y light spring being interposed between the l spider and the said valve 11 and suitably i connected with the latter to normally in a closed position. Under weight l of the water when the same is poured in the said substantially funnel-shaped top of the boiler the valve will be automatically opened.

In the form of my invention shown in Fig. 4., the boiler is formed of two parts 14 and 15, each part being substantially identical. in construction and formed with an inner wall 16 and an outer wall 17. The inner walls are formed with the concavities 18 whose walls will fit the stove pipe. The seei tion 15 is formed with a clasp 19 to engage a keeper 20 on the section 14: so as to he 6. both sections operatively associated on the f pipe. Each section is provided with a suitable draw-othcock 21. \Vith other respects 1 the modified form of my invention last described is identical with the preferred form ,and further detail description is believed unwarranted. The boiler constructed on lines as described while being useful for domestic purposes will be found most efiicient in barber shops where it is desired to obtain small quantities of water for shaving cups or like purposes.
