LEO I-I. MERES, OF LORAIN, OHIO, ASSIGNOR OF ONE-HALF TO STANLEY GRIFFIN, OF ELYRIA, OHIO.

WATER-HEATER.

Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed January 1O 1905. Serial No. 240,492.

To all whom, it may concern.-

Be it known that I, LEO 11. Means, a citizen of the United States, residing at Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in ater Heaters or Boilers; and I. do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in water heaters or boilers.

The object of the invention is to simplify and cheapen the construction of devices of this nature and to provide a compact, durable, and eflicient heater which can be readily repaired when necessary and in which a large amount of heating-surface is provided.

With this object in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings,

forming part thereof, in which- Figure 1 is a rear perspective view of a water-heater constructed in accordance with the invention, parts of the brick walls or casing being broken away. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a vertical cross-sectional view of the same. Fig. 4 is a cross-sectional view, on an enlarged scale, of one of the water-tubes, showing the partition for circulating water through said tubes.

Referring more particularly to the drawings, 1 denotes the heater, which is preferably set into or incased by walls 2 of masonry. The front of the heat-er consists of a flat rectangular box 3, of cast-iron or the like, which forms a manifold for the entire front end of the heater. In the lower portion of this manifold-front are formed suitable openings 4 and 5 to permit access to the lire-box and ash-pit.

On the inner side of the manifold, between openings 1 and 5, is secured a ledge or shelf 6, on which rests the forward ends of gratebars 7 which forms the bottom of the firebox. The rear or inner ends of the grate-bars are supported by a short masonry wall 8.

On the wall 8 rests a horizontally-disposed manifold or drum 9, from which extends a series of upwardly-projecting tubes 10, which forms the back or bridge wall of the fire-box. The pipes 10 are connected at their upper ends to forwardly-extending horizontally-disposed tubes 12, which form the upper side of the fire-box, the tubes 10 and 12 being spaced apart to permit the flame to pass through. The forward ends of the tubes 12 are threaded and are screwed into threaded apertures formed in the inner wall of the manifold-front, and thus communicate with the interior of said manifold.

The sides of the lire-box are formed by vertical stacks of horizontal longitudinally-disposed tubes 13, there being preferably two vertical rows of tubes in each stack and the tubes in one row of each stack being disposed opposite the space between two tubes of the adjacent row. In other words, the tubes in each stack are arranged in a zigzag manner, as clearly shown in Fig. 3 of the drawings. The inner ends of each of these tubes are closed by caps 14. The lowermost tube 15 in .each stack is somewhat larger than the rest of the tubes and forms the return-pipe to the manifold.

Above the stacks of tubes 13 is arranged a transverse or horizontally disposed flamesheet 16, which extends entirely across the furnace from one side wall to the other and is supported at its forward end upon a ledge or shelf secured to the inner wall of the manifold, said end closely engaging said wall. At its inner end the plate or sheet 16 is provided with an opening to permit the passage of flame and smoke upward.

Above the flame plate or sheet 16 is arranged a horizontal row of longitudinally-disposed tubes 17, spaced slightly apart and closed at their inner ends by caps 18. The outer ends of the tubes 17 are threaded and screwed into threaded openings in the inner wall of the manifold 3. Immediately above this row of tubes is arranged a horizontallydisposed flame-plate 19, which extends from one side wall to the other. This flame-plate does not extend entirely to the inner wall of the manifold, so that a space 20 is formed through which the flames may pass after passing forward beneath and between the tubes 17. Near the inner or rear end of the plate 19 is formed adraft-opening 20, said opening being normally closed by a damper-plate 2.1, which may be operated from the outside of the heater by any suitable shifting mechanism. (Not shown.)

Above the plate 19 is arranged a second row of horizontal longitudinally-disposed tubes 22, which are spaced apart and closed at their in ner ends by caps 23, the forward ends being threaded and screwed into openings in the manifold 3 in asimilar manner as the tubes 17.

In one or the other of the masonry side walls between the plate 19 and tubes 22 near the inner ends of the same is formed a smokeflue which communicates with a smoke-stack. (Not shown.)

Above the tubes 22 is arranged a horizontal top or roof plate 23, which is preferably formed of corrugated iron. Above the plate 23 and supported thereby is a roof 24: of masonry.

The upper end of the manifold-front 3 extends above the roof 24 and the top wall of the manifold converges from each side toward the center, where it is connected with the discharge-pipe 25.

On the outer corners of the sides of the manifold are formed flanges 26, in which are formed apertures to receive the ends of studbolts, (not shown,) but which are set into the front ends of the masonry side walls. On the outer ends of these bolts are screwed nuts which bear against the outer faces of the flanges 26, thereby holding the manifold and tubes in place within the masonry walls.

In each of the tubes having capped inner ends is formed a longitudinal horizontallydisposed partition 27, which is preferably S shape in cross-section, as clearly shown in Fig. 4:. This partition extends from the forward open end of each tube to within a short distance of the inner closed ends of the same, thereby forming two passages in each pipe through which the water from the manifoldfront circulates and is heated.

The normal course of the flames from the fire-box is indicated by full-line arrows. WVhen starting the fire or whenever an increased draft is required, the damper-plate 21 is shifted to open the passage 20, which causes a direct draft from the fire-box to the smoke flue and stack, this line of draft being indicated by broken-line arrows. When the damper is closed, the flame is directed by the flameplates to cause it to pass under and between the horizontal rows of tubes, thereby heating the water nearly to its discharging-point.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended explation.

Various changes in the form, proportion,

and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
