Patented July 19, 1932 PATENT JOHN IlIAYlElItIHIOFER, OF BROOKLYN, NEW YORK HOT WATER HEATER Application filed February 12, 1931. Serial No. 515,367.
The present invention relates to hot water heaters and the primary object of the invention is to provide an improved heater for installation in coal or oil burning furnaces for heating water for household or various other purposes where a supply of hot water is desired.
A further object'of the invention is to provide'a hot water heater which may be economically constructed in the form of a metal casting and embodying features permitting ready and easy cleaning out of the heater without requiring removal of the heater from the furnace. J
A further objectof the invention resides in the novel manner in which the heater is associated with the fire pot or box of the furnace for most effective heating.
7 A further object of the invention is to provide a hot water heater adapted to be so arranged in the fire box section of the furnace as to prevent formation of dead spots about the heater and thereby obtaining full heating efficiency.
A further object of the invention is to provide hot water heating unit adapted to be mounted in surface contact with the inner wall ofthe furnace.
Other objects and advantages of the invention will be apparent during the course of the following detailed description, taken in connection withthe accompanying drawings forming a part of this specification and in which drawings: -Figure 1 is a fragmentary sectional view thru a furnace showing the improved heating unit applied and connected to the hot water storage tank.
Figure 2 is a ing unit.
Figure 3 is a plan. view of the front for concaved side of the heater unit.
Figure 4 is a plan. view of the rear or convex side of the heater unit and showing fragmentary portions broken away.
Figure 5 is a central vertical section thru the heater unit. I
Figure 6 is a horizontal section thru the heater unit at one of the coupling bosses.
perspective view of the heat- Figure 7 is an enlarged horizontal section substantially on the line 77 of Figure 1.
In the drawings, and wherein similar reference characters designate corresponding parts thruout the several views the improved heater unit A has been shown associated with a conventional type of furnace B which in the example shown is of the round boiler type. The letter C may designate a suitable storage tank for the hot water and is connected in circuit with the heater unit A.
The furnace B may either be of the coal or; oil burning type and embodies the round fire pot section-5 below which is arranged the usual grate 6. The circular wall 7 of the fire pot section 5 is provided with the usual openings 8 arranged in spaced vertical alignment and ordinarily spaced about six inches apart. These openings 8 provide entrance ways for the cold water inlet pipe 9 and a hot water outlet pipe 10, the pipe 9 passing thru the lower opening 8 and the pipe 10 passing thru the upper opening. The openings 8 are of greater diameter than the pipes 9 and 10 to permit ready and easy placing of the pipes and allow for expansion and contraction. In usual practice the heater unit connected with the pipes 9 and 10 is disposed in spaced relation to the furnace wall and extends into the fire bed. In the improved heater unit herein shown, the unit is mounted in surface contact with the furnace wall 7 similar to the mounting of a water back in ahousehold range.
Referring now to the construction of the heater unit A, the same is preferably of a one-piece casting having a transverse curvature corresponding to the curvature of the furnace wall 7. The unit may be cast of iron or brass and is preferably of greater height than width. The unit is curved transversely providing a convex rear wall 12 and a concaved front wall 14 connected along their vertical edges by end walls 15. Closing the up- 9 per end of the heater unit is a top wall 16, while closing the lower end of the unit is a bottom wall 17. The unit provides an arcuate water chamber18. 1 I I Formed at the vertical center of the convex rear wall l2 are upper and lower bosses 20 and 21 respectively which are drilled and tapped as at 22 providing openings thru the bosses to the chamber 18. The bosses 20 and 21 are spaced on their centers, a distance equal to the spacing of the openings 8 and have an external diameter of a size to fit snugly in the openings 8, so that the outer surface of the arcuate wall 12 will have surface contact with the circular furnace wall 7 particular dimensions of the heater unit, a-
unit having the following dimensionsw'has been found satisfa'ctoryfor use in domestic furnaces. vThe heater may have a heighto-f ten inches, a width ofseven inches and athickness 'of about one andone-half inches with h the bosses and'21spaced six inches apart on their centers to correspond with the standard spacing of the furnace openings 8. "The upper boss 20 providing the hot-water out 1 let for the chamber 18 may be spaced one and one-half inches from the top wall16,
while the lower boss 21 providing the cold 7 a5 'water'inlet for thechainber 181 may be'spa'ced two and one-half inches from the bottom Wa f t Provided in e'ach'lof the'upper and lower walls 16 andl'i'" are two tapped openingsf28 I 1,30 for re'ceiving threaded plugs 30. These openings28 provide clean-outiopenings and during casting of the unit permit proper supportingof the core for formation of the chamber 18. These clean-out plugs 30 will permit thorough cleaning of the chamber 18 without requiring removal of the heater unitfrom the furnace. v I
r The lower boss 21 receives the cold water inlet pipe 9 while the upper, boss 20rec'eives wrthe hotwater outlet: pipe 10. Thepipes 9 and '10 are connected by unions 30 to pipes .31 and 32 respectively andwhich pipes 31 and 32 are connected in the usual manner to' the storage tank G. r V
In installing the heater unit, the bosses '20 'and2l'are inserted into the openings 8 With or the upper boss 20 fitting infthe upper opening 8 so that the smooth external surface of p the convex rear wall 12engages-the inner .surface of the circular furnace wall 7,1This contacting of the walls 7 and 12' eliminates the formation of anypockets at the rear of furnace wall without requiring special fastening means for retaining the unit in p0- sition. r 7
Changes in detail may be made to the form of invention herein shown and described, While I do not care to limit myself to any without departing from the spirit of the invention or the scope of the following claims.
I claim: I
' 1. In combination with a furnace including a fire pot section having openings formed thru the wall thereof; a hollow water heater unit disposed in surface contact with the inner sideof the fire pot wall and having hollow bosses snugly fitting into said openopenings formed thru the'wall thereof; a 1101- 1 low one piece water heater unit disposed with one side in surface contact with the inner" side of the fire pot wall, and'bosses on the contacting side of the unit snugly fit-- ting into theopenings thru the fire pot wall,
said bosses having threaded openings therethru for threaded connection of inletandoutlet pipes.
3. In combination with a.furnace including a firepot sect1onhav1ng a circular wall provide d with apa ir of vertically spaced openings; a" hollow arcuate shaped water heater unit disposed with its convex side in surface contactwith the inner sideof the lire pot wall, said unit being of greater height than width, a tapped boss adjacent the upper end'of the convex side of the unit for fitting into the upper opening thru the fire pot wall, and a tapped boss adjacent the lower end of the convex side of the unit for fitting into the lower opening thru the fire potwall.
'JOHN F. MAYERHOFER.
the heater unit for the collection of ashes between the heater unit and furnace wall. The extending of the bosses 20 and 2'1 into the openings sane serve to support the heater unit in place without requiring any fastening 'means such as bolts or the provision of look- (ing members upon'the pipes 9 andIO. v
'From the foregoing it will be apparent that a novel and efficient type of hot water "heater has been provided which may be disposed in the-fire pot section of a furnace in such manner as to obtain the greatest'amount.
of heating efliciency It will also be-apparent
