RADIATOR Box BASE.

Application filed August 28, 1926. Serial No. 132,169.

This invention relates to improvements in housing boxes for steam radiators, and more particularly to the box .base and manner for connecting said box base with the superimposed sides of the box.

Heretofore the sides and base have been lapped and riveted together, with the result that unequal expansion has caused the box members to buckle and spread apart between the rivets, thereby reducing the draft through the housing box, and admitting vitiated air to the box from the room in which the radiator is located, instead of drawing in fresh air from outside of the building, as is desired. I

One object of this invention is to provide a simple slip-joint between the box base and walls, that will not buckle nor open up but which will be practically air tight under all temperatures and .all conditions of use;

Another object is to make the base as well asthe box, in two separable parts, adapted to be assembled at the rear and front, respectively, of a radiator, the box and base members for the rear being capable of complete assembly, for convenience, before those for the front are assembled.

A further object is to improve on the details of construction in a manner which will hereinafter appear and which will be specified in the claims. j

I accomplish the above objects by the construction illustrated in the accompanying drawing, in which- Fig. 1, is a perspectlvely view of a steam radiator with my invention in operative assembly therewith;

Fig. 2, is afragment in perspectiveof a invention and herebox base embodying my shown detached from e, radiator coils, but

' with a box front in vertical section, in posishown in Fig. 2, but without the box front being shown; I

4-4 of, Fig. 1, except that the front of the box base is lowered as in Fig. 2;

Fig. '5, is an enlarged cross section of the the. box.

In this embodiment Fig." 4, is a vertical section on the line joint between the box and base shown in Fig. 4;

Fig. 6, is a section on the line 66 of Fig. 1 showing a detail of the slip joint bebox; Fig. 7, is a front view of the plate which is inserted to close the space above the bosses at the steam connections between the radiator coils; and

Fig. 8, is a sectional detail similar to Fig. 5, showing a modified form of joint.

Like characters of reference indicate like parts in the several views of the drawing.

The coils 8 are of a construction usual to steam radiators. They have bottom openlngs for the passage of steam, surrounded by bosses 9, from which the box base 10 is suspended by bolt hooks 11, which ass through eyes 12, projecting from the en s of 13 is the radiator containing box.

As the box and base are both assembled after the radiator is installed, they are both made in two longitudinally separable parts.

vThe box base' 10, has a tubular extension 14 on its wall side corresponding in size and shape-with the air duct through the wall of the house to the outside air. This tube is surrounded by a flange 15 which is fastened flat against the wall around the opening,

l for substantially the whole length of the box, is a hole 16 which is opened and closed Iliy a door 17 hinged at its edge next to the an 'e.

The ends 18, 18, of the box have'openings 19 for the passage therethrough of the bosses 9, and in practice the metal above the opening is removed as shown for greater convenience in assembly with the radiator, but this is not essential. The separation. of

the base into twoparts, front and rear, is

accomplished by dividing the ends 18, 18, on the lines 20, which extend diagonally beginning with the outer corners of the hole 16.

An angle bar 21 is riveted to the inside bottom of the back base member with an end overlapping the bottom of the front member, to whichand to the adjacent side of the base, the end is removably secured by screws.

, This angle bar construction is duplicated for and' united. v

curve 23, to form a recess for a channel bar 24:, here shown as formed out of a strip of corrugated sheet metal having one edge bent and hooked over edge 22, and the opposite portion bent to form a channel 25. Preferably the edge opposite the hook is bent in, as shown in Fig. 5, to reinforce and finish that edge, and also, to lower that side of the channel sufliciently below the opposite side to cause the latter to act as a guide in slipping the edge of the front box member into place'in the channel. Without such projection the edge under insertion would buckle or push past the channel. but with it, the PI'OJGCiJlOIl arrestsandguides the metal sheet into the channel.

Ears 26, at the ends of the channel bar,'

are formed out of the latter and are bent over against the ends of the base and are spot-Welded or riveted there.

A similarly formed channel bar is hooked over the top edge of the rear member of the base.

In Fig. 8, is shown a channel bar of a modified form in which the bar, instead of having a hooked edge to hook over the base is secured to the latter by rivets.

The box proper is preferably formed out of corrugated sheet metal, in two major members 27 and 28, divided midway at the ends, vertically, and united by .slip joints '29, (see Fig. 6). The top longitudinal edges are stiffened and finished by rolls 30, and the ends by channel bars 31 The open spaces existing at the ends or the base above the bosses 9 are closed by plates 32. Each plate makes a snug fit against the front and back walls of the box and has a bottom, half-round recess 34.- to receive the boss on which it rests when in use.

This invention may be varied without de-.

parting from the spiritof the invention, and I therefore do not desire to be limited more than is required by the appended claims.

I claim: 1. A radiator box base having end members with half-round openings at their bottoms and having a bottom door opening in the rear half of the base, said base being in two parts divided longitudinally of the bottom at the front line of the door opening and obliquely from the door opening toward the middle of the half round openings and means for-removably securing the parts in assembled position.
