FURNACE.

Specification of letters Patent.

Patented Jan. 18, 1921.

I Application filed'June "-11, 1919. Serial no. 303,336.

To all whom it may concern:

Be it known that I, GEORGE W. Howns, a citizen of the United {States, residing at Dowagiac, Michigan, have invented certain new and useful Improvements in Furnaces, of which the following is a specification.

This invention relates to improvements in furnaces.

The main object of this invention is to provide an improved furnace whichmay be adjusted to face asdesired, and direct chimney connections from the radiator maintained.

Further objects, and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly'defined and pointedout in theclaims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawin s forming a part of this specification, in w ich:

Figure I is a side perspective view of a structure embodying features of my invention parts only of the casing being shown.

Fig. II is a detail plan view of the lower section of the radiator.

Fig. III is a plan view of the base.

Fig. IV is an enlarged detail horizontal section on a line corresponding to line ie-4 of Fig. I.

Fig. V is a detail side perspective showing the radiator adjusted to a position at right anglesto its position in Fig. I.

Fig. VI is a fragmentary detail plan view with the upper portion of the radiator removed, parts of the casing being shown in section. i

Fig. VII is a detail section on a line corresponding to line 7-7 of Fig. VI.

Fig. VIII is a side perspective view with the outer casing removed.

In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawings, the furnace body in the structure illustrated is formed of sections 1, 2, 3 and 4, section 1 being the ash pit section and the sections 2, 3 and 4 forming the fire pot and combustion chamber. The base 5 is designed to receive the extension ltdisposed oppositely. The front wall 15 is provided with an opening 16 with whlch the clean-out 1.4 may be brought into 7 re ister.

The front wall is securedto the ash pit and the fire pot passages by means of bolts 17 arranged through lugs 18 provided on these passages. The front wall is provided with "forwardly projecting flanges 19 to which-the outer casing 20- is secured by bolts 21. The inner casing 22 is double walled in the structure illustrated, its lower edge be ing mounted on thefring 23 supported by uprights 24 on the base bars 7.

The inner casing members have lapping flanges 25 which overlap the flange 19, these casing membersbeing supported by the eye bolts 26 engaged on the inner ends of bolts 17 which secure the front wall to the furnace body, the bolts 17 being provided with nuts 27 on the inner sides of the lugs and nuts 28 to retain the eye bolts.

The furnace illustrated is one of the one register type, the register not being shown, as such registers are known in the art and form no part of this invention. It is sufiicient to say that the connections are made so that the air circulates downwardly in the outer casing and upwardly about the furnace body and radiator.

To permit the positioning of the furnace in its most convenient relation, that is to provide for facing it without regard to the chimney, the radiator is arranged so that it maybe mounted in different positions relative to the body. This I accomplish by providing the base 5 with a series of lugs 29 and the radiator with a plurality of lugs 30 adapted to be brought into vertical alinement with the lugs 29, so that the tie bolts 31 may be engaged therewith. These tie bolts are centered, that is their pull is cen tered without regard to the adjustment, so that they serve not only to hold the radiator in place, but to clamp the furnace sections together, thereby avoiding the necessity for separately bolting the several sections together and clamping them together so that the joints do not open under expansion or under the shocks of such explosions as are likely to occur on account of the accumulation of gas.

I have not illustratedthe particular form of joints for sections, as suitable nesting and seating joints are known in the art. In Fig. I, I show the radiator with its clean-out registering or connected to the opening 16 in the front wall. In Fig. VI, I show it disposed at right angles to the position shown in Fig. I. When thus arranged I provide a clean-out extension 32 which is disposed be tween the inner and outer, casing members,

and secured to the flanges on clean-out 14 by bolts 33, a gasket 84 being arranged between the flanges to provide a secure joint at this point. The extension 32 projects through the outer casing and is provided with a door or cover 35.

My improved furnace is designed so that it may be shipped knock down and set up or assembled at the place of installation by an unskilled workman. This is particularly feasible where my improvements are em bodied in a one register furnace as illus trated. However, certain of my improvements areadvantageous for use in other types of furnaces. I have not attempted to illustrate ordescribe such other adaptations or embodiments as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or I claim as new and desire to secure by Letters Patent is:

1. The combination of a furnace body having a plurality of spaced tie bolt holes, a front wall secured to said furnace body and having a clean-out opening therein, an annular radiator seated on said body and having a smoke flue and a clean-out extension adapted when said radiator is adjusted to one position to register with said front wall clean-out opening, said radiator having a plurality of tie bolt holes disposed to aline vertically with the holes on said body with the radiator in different adjusted positions relative to the body and, tie bolts engaging alincd holes of said body and said radiator.

2. The combination with a furnace body having a plurality of spaced tie bolt holes, of an annular radiator seated on said body and having a smoke fine and a clean-out extension, said radiator communicating with the combustion chamber of the furnace through a central opening, and having a plurality of tie bolt holesspaced to aline with the holes on said body with the radiator adjusted to different relations relative to the body, and tie bolts extending from and engaging alined holes of said body and radiator, all coacting for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.

GEORGE IV. HOWES.
