'9 rNvENToR ROBERT s. WATERS @YW ATTORNEY Y"April 1e, 1963 United states Patent one@ 3,085,350 Patented Apr. 16, 1963 3,@3135@ PRABE HEATER Robert S. Waters, Lexington, hio, assigner to Westinghouse Electric Corporation, East Pittsburgh, Ia., a corporation or Pennsylvania.

Filed Dec. 1, 19nd, Ser. No. 72,9lt9 6 maints. (Ci. Eid- 91) This invention relates to space or room heaters, more particularly to portable heaters of this type, and has for an object to provide, in combination therewith, novel means for supporting articles to be dried by heat from such heaters.

Another object of the invention is to so arrange both a carrying bar and a drying bar for a portable space heater that each cooperates with the other to promote satisfactory performance of their respective functions.

Brieily, the invention, in a preferred form, utilizes a pair of horizontal bars, maintained in spaced parallel relation by side arms joined at their ends remote from the bars and pivotally connected, adjacent the joined ends, to the heater for limited pivotal movement or" the assembled bars and side arms. At one limit of pivotal movement of the assembly one of the bars is positioned above the heater substantially in vertical alignment with the center of gravity of the heater, this bar thus providing a handle or carrying bar for the heater. In this position the other bar is disposed behind the heater adjacent the lower edge thereof, and preferably is releaSably latched there. At the other limit of pivotal movement of the assembly the other bar is disposed above and in front of the heater so that fabrics or other articles hung on this bar to dry are positioned in the path of heated air discharged from the heater. This bar is referred to as a drying bar and is retained in its `drying position by engagement of the carrying bar with the front of the heater.

The foregoing and other objects are effected by the invention as will be apparent from the following description and claims taken in connection with the accompanying drawings, forming a part of this application, in which:

FIG. l is a perspective view of a portable room heater incorporating the invention;

FIG. 2 is an end elevational view of the structure shown in FIG. l;

FIG. 3 is a View similar to FIG. 2, but showing the bar assembly in a dierent position; and,

FIG. 4 is an enlarged fragmentary sectional view taken along the lines IV--IV of PEG. 3, looking in the direction indicated by the arrows.

The space or room heater 1o, illustrated in the draw* ing, includes a base 11 on which is secured a casing l2, the latter including a top wall 13, side walls 14 and a rear wall 16 and having an open front 17 protected by conventional grille Work 13. Preferably, the base 11 is provided with a plurality of feet i9 to space the base from any supporting surface on which the heater may be placed, such as a door, table top, shelf or the like.

The casing 12 houses the usual heating element 2l., surrounded on the four sides and the rear by a reiiector 22 for directing radiant and reflected heat forwardly through the open front 17 of the casing. A fan 23 may be housed in the base 1i for drawing air in through the bottom of the base and forcing it upwardly and forwardly around the outside of the reflector and exhausting it through `a peripheral space between the reiiector forward edge and the casing walls.

The construction described heretofore may be considered as conventional, applicants contribution relating to the combination with such a heater of the novel bar assembly, indicated in its entirety by the reference character 25.

This bar assembly 25 includes a carrying bar 26 and a drying bar 27 ydisposed in horizontal parallel spaced relation and maintained in such relation by s-ide arms 28 integral with the ends of the carrying bar 26 and side arms 29 integral with the drying bar 27.

rifhe

side arms

28 and 29 are permanently joined, at their ends remote from their respective bars, as at 31, by welding, brazing or the like. It will be apparent from consideration of FIGS. l, 2 and 3 that the side arms 28 lie in a plane displaced a substantial degree from the plane in which `the side arms 29 are disposed.

The terminal portions of the side arms 28, adjacent the welded connection between the

side arms

28 and 29, are disposed in a horizontal plane, parallel to the

bars

26 and 27 and serve as journals for pivotal mounting of the bar assembly 25. Such pivotal mounting of the -bar assembly is elected by disposition of the journal portions 32 in aligned openings 33 in the casing side walls 14. The journal portions 32 are retained in the bearing openings 33 by means of conventional toothed lock washers 334i engaging the inner ends of the journaled positions 32. Washers 35 are positioned on the journal portions 32 between the casing side walls 14 and the joined side arms 2S and 29 to prevent rubbing of the arms against the side walls.

With the bar assembly 25 journalled in the casing side walls for pivotal movement with respect to the heater, the assembly may be pivoted between the two limits of movement illustrated in FIGS. 2 and 3.

In the position illustrated in FIG. 3, the carrying bar 2d is positioned substantially directly above the center of gravity of the complete heater 10 and the drying bar 27 is disposed adjacent the rear wall 16 of the heater, in close proximity to the bottom edge of the base 11, where it is substantially concealed when the heater is viewed from the front. A resilient clip 36, carried by the base 1l, cooperates with the ldrying bar 27 to retain the latter in the position shown in FIG. 3.

When it is desired to utilize the drying bar 27, the bar assembly 25 is pivoted to the position illustrated in FIG. 2, in which position the drying bar 27 is disposed horizontally above and forwardly of the open front 17 of the heater where fabric articles or other articles of wearing apparel or the like which are to be dried when hung on the bar 27 will be positioned in the flow path of hot air discharged through the open front of the heater, this llow path being indicated by the solid arrows in FIG 2.

The weight of articles hanging on the drying bar 27 when the latter is in the drying position of FIG. 2 would tend to pivot the bar assembly counterclockwise were it not for the fact that the carrying bar 26 engages the front of the casing 12 to retain the drying bar in its drying position.

The above description of the operation of the two

bars

26 and 27 renders obvious the necessity for disposing

side arms

23 and 29 in angularly-disposed planes.

It is believed apparent from the above description that applicant has provided a unique bar assembly provided for both ready manual transportation of the portable heater 1@ and convenient drying of articles by use of the heat discharged by the heater.

While the invention has been shown in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modiications without departing from the spirit thereof.

What is claimed is:

l. In combination with a portable space heater, a pair of bars, means connecting said bars in spaced parallel relation, means mounting said bars for pivotal movement relative to the heater between a rst position where one of said bars overlics the heater approximately above the center of gravity of the latter and the other bar abuts the heater to limit pivotal movement of the bars in one direction and a second position in which said other bar is disposed above and generally forwardly of the heater and the said one bar abuts the heater to limit pivotal movement of the bars in the opposite direction.

2. In combination with a portable space heater, a carrying bar and a drying bar, means hxedly connecting said bars in spaced parallel relation, means mounting said connected bars for pivotal movement relative to the heater between a rst position where the carrying bar overlies the heater approximately above the center of gravity of the latter and the drying bar abuts the heater to limit pivotal movement of the bars in one direction and a second position in which said drying bar is disposed above and generally forward of the heater and the said carrying bar abuts the heater to limit pivotal movement of the bars in the opposite direction.
