Application filed March 26, 1923. Serial No. 827,654.-

citizen of the United States, residing atv 7 New lBedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Heating Furnacea'of which the following is a specification.

This invention relates to certain new and useful improvements in furnaces and pertains more especially to furnaces employed in the heating of dwellings.

The primary object of the invention is to provide a heating furnace which utilizes a maximum of the generated heat and one which is equally adaptable for use with either water or air.

A further object of the invention is to provide a furnace of simplified and economical construction, and: one wherein lateral alternating or staggered fluid holding sections or conduits are provided, which project into the path of the ascending heat so as to necessitate tortuous travel of the latter from the fire chamber to the stack.

. A still further object of the invention is to provide fluid containing or holdin conduits which efiect travel of the heats fluid horizontally in thin or film-like sheets throughout the depth of the furnace and substantially throughout the width thereof and to also provide interchangeable sections a which can be easily applied in position and removed.

Another object of the invention is to provide a furnace in which theinterior of the heat chamber is rendered freely accessible I for cleaning purposes.

The invention has still further and other objects which will be later set forth and manifested in the course of the following Figure 6, is a front elevation of one of the fluid-receiving sections, and

Figure 7, is a detail view of one of the joint-formin bushings.

lln proceeding in accordance with the. present invention, the opposed side walls of the furnace body are provided with series of spaced vertical water or air conduits 2, the

ends of which conduits curve inwardly toward the interior of the heat chamber 3. As i illustrated in Figure 3 of the drawings, the ends of the conduits in one side wall of the furnace body occur in horizontal planes alined with the central portions of the con duits of the opposed side wall. The lower ends of the lowermost conduits are provided with coupling nipples e and into which the water or air is conducted for heating, while the upper ends of the uppermost conduits are in register with ports 5 formed in the head or top 6 of the furnace. Nipples 7 for connection with distributing pipes are carried by the top 6, the pipes (not shown) being connected to radiators, as usual. A

smoke pipe 8 is also carried by the furnace 77 top. In order to form air or water tight joints between the conduits and the outlet ports 5 of the head 6, nipples or bushings 9 are employed, the nipples having the opposite sides of their peripheries beveled from a meeting point central of the width of the rings and are fitted in countersunk portions corresponding to the beveled portions and formed in the furnace-top and body sides as illustrated in Figure 3 of the drawings.

The adjacent ends of adjacent conduits are connected by fluid receiving sections which approxihavin Q m nds 2.9,,

embody a preferably liOflZODtEi. mately rectangular hollow casi g upper sides 10, iower sides ll, re

front ends 12 curved front 13 and wail 14-, the upper and lower sides having central tiered portions 15. in. or outer walls 14: are formed with one 16 and 17 which register with the tions 15. Nipples or bushings l8 s nipples 9, are also employed to r water or airtight joint between the 17 and the curved ends of the continue, as depicted in Figure 3 of the draw' The fluid receiving sections formed with central partitions or divxcnns plates 19, which terminate short of the curved front or inner ends of the sections, and which divide the latter into upper and lower chambers to cause spreading of the water or air entering the sections, into relatively thin film or sheet like formation. The rear or outer walls 12 of the sections and the division plates 19 are formed with perforated bosses 21, merging into the walls and plates, bolts 22 being employed and which are projected through the side walls 1 of the furnace body and into the bosses so as to removably secure the sections in position.

The furnace body is preferably of ap proximately rectangular cross-section, and is provided with a hinged door 23 extending over approximately the entire front of the heat chamber, so that by opening of the door the entire interior of the heat chamber is rendered freely accessible for purpose of cleaning or repair. In the latter regard it will be noted that the sections are not only interchangeable but that same can be easily and quick y removed for purpose of cleaning the interiors thereof, or for the purpose of replacing burnt-out sections or ones otherwise, through wear or defect, rendered unfit'for further use.

The combustionchamber or fire box is I closed by a door 25 the heat being produced by either wood, coal, gas or oil. The rear end walls 12 of the sections closely abut the rear wall 30 of the furnace body, while the front end walls 12' thereof are engaged by the door 23.

In operation, water or air enters the conduits at the lower ends thereof and upon heating flows upwardly and entering the hollow lateral sections flows first beneath the division plates 19, thence above the latter and into the next adjacent conduit 2 which path of travel is repeated until the heated fluid egresses from the ports 5 and then enters the distributing pipes. The fluid is thus given a vertical and horizontal path of travel, resulting in effectual heating thereof. At the same time, the products of combustion must follow a. tortuous path of travel from the fire box to the stack, same contacting not only with the vertical side walls of the furnace, but also with the lower and then with the upper sides of the sections.

What is claimed is:-

1. In a heating furnace, a substantially rectangular body having a series of vertical spaced conduits in two opposed side walls of the body, the adjacent ends of the conduits extending inwardly and opening through the inner side faces of the said walls, a series of hollow fluid-receiving sections for each of said walls having rear ends abutting the rear wall of the furnace body and havino' outer walls abutting said opposed walls o f' the furnace body respectively, said outer walls of thesections having upper and lower openings registering with the adjacent ends of adjacent conduits and the upper and lower sides of the sections having central flared portions registering with said openings respectively, a division plate in each section extending from said outer walls thereof and between the upper and lower sides of the sections and spaced from the front walls of the sections, screw bolts extending from the outer faces of said opposed side Walls into the sections to hold the latter in place, and a door engaging the front ends of the sections.

2. In a heating furnace, .a body having two series of opposed and horizontally arrari ed hollow fluid-receiving sections, the sections of the series being staggered and connected at their rear portions to the respective side walls of the body'and having their front portions spaced from the op posed side wall to form a vertical tortuous heat passage, division plates in the sections abutting the rear portions of the sections and spaced from the front portions. thereof, and a series of spaced vertical conduits in each of the side walls of the body, the adj acent ends of adjacent conduits being in communication with the sections at the respective points above and below the division plates, and screw bolts extending from the outer faces of the body inwardly into engagement with the sections to hold the latter in position.
