The invention herein presents a heat xture useful for various purposes but devised to be especially useful for warming outbuildings, such, for example, as farm milk houses.

The heat fixture is constituted as a hollow body supporting channel members with which heating lamps are assembled and providing a housing for lead wires to the heating lamps.

The object of the invention is to provide a heat xture of the character as stated wherein will be incorporated simple, inexpensive, practical, efficient, novel and improved features of construction.

Fig. 7 is a detail sectional view illustrating the manner in which channel members of the heat fixture are supported upon a hollow body thereof; and

Fig. 8 is a wiring diagram of an electrical system of the heat xture.

Speaking generally, the new and improved heat fixture consists of a hollow body supporting channel members with which heating lamps of said heat xture are assembled and providing a housing for lead wires of an electrical system in which said heating lamps are adapted to be connected. In practical use, the hollow body oi the heat xture ordinarily will be supported upon a building structure, as from a ceiling, denoted I0, such as the ceiling of a farm milk house or other outbuilding.

A hollow body of the heat fixture is constituted as a generally rectilinear member consisting of spaced, parallel, first and second base walls, indicated II and I2, respectively, spaced, parallel, opposite Side walls I3, I3 and spaced, parallel, opposite end walls I4, I4. The side and end walls are perpendicular to each other and to the first and second base walls, and all of said side, end and base walls are joined at their locations of meeting.

The opposite side margins or the second base wall I2 terminate in equally spaced, parallel relation to the side walls I3, I3, thus to provide rectilinear openings I5, I5 at the opposite sides of said second base wall between said opposite side margins and said side walls spanning the distance between the end walls I4, It. Opposite side portions of the second base wall extend inwardly of the hollow body and toward each other to provide interiorly projecting, oblique bounding walls I6, IB at the opposite sides of an interior surface I'I of said second base wall.

Each of a pair of parallel channel members of the heat iixture is designated I8. t is to be understood, however, that a heat ixture made according to the invention can include a greater or less number of channel members.

Each of the channel members is constituted as an elongated base I9, spaced,

elongated side walls

29, 20 extending away from opposite side edges of the elongated base, and spaced, parallel, end walls 2|, 2I contiguous with the opposite ends, respectively, of the elongated base E9 and the

elongated side walls

29, 29. The side and end walls of each channel member are in perpendicular relation to each other and to the elongated base, and each channel member is open at its side opposite its elongated base save for an overhanging flange 22.

The channel members I8, I8 are situated in the hollow body of the heat xture with their elongated bases I9 and exterior portions of their elongated side walls 20, 2D and end walls 2i, 2i disposed in or adjacent to the rectilinear openings I5, I5, and each channel member is supported upon said hollow body for rotative movement. More explicitly stated, each of the end walls 2i of each channel member I8 is supported upon a pivot element 23, disclosed as small screw bolts, situated in the adjacent end wall I4 of the hollow body, for rotative movement of the channel members in a plane perpendicular to the rst and second base walls II and I2. The construction and arrangement will be such that while said channel members substantially lill the rectilinear openings I5, I5 they will be free for limited rotative movement in said hollow body. Each pivot element or screw bolt 23 has a slotted head disposed at the exterior side of the corresponding end wall I4 and supports a spring nut 2t to be engaged against the interior surface of the corresponding end wall 2l. Lugs 25, one for each spring nut, struck interiorly from the end walls 2l are for precluding turning movement of the spring nuts. The end walls 2l are adapted to be frictionally grasped against the end walls I ll,

thus to preclude rotative movement of the channel members, in response to turning home actuation of the pivot elements or screw bolts 23 after said channel members have been rotatably adjusted to any position relative to the hollow body of the heat fixture which may be predeterminedly selected. The construction and arrangement desirably can be such that when the elongated bases I9 of the channel members I8 are parallel to the first base wall I I said elongated bases will lie in a single plane substantially alined with the second base wall I2, as in Fig. 6 of the drawings.

Perforations 23 through the first base wall II are for receiving fastening means 2l, screws as shown, for securing the heat fixture to a ceiling, such as I0, or to some other supporting structure.

The elongated bases I9 of the channel members I8 support heating lamps 28, and the interior surface Il and oblique bounding walls IB, I6 of the hollow body of the heat fixture together provide a housing for lead vwires tosaid heating lamps.

An end wall I4 of the hollow body suitably and conveniently supports an insulating bushing 29,

disposed between and in spaced relation to the channel members I8 inalined relation to the lead wire storage space provided by said interior surface I'I and oblique bounding walls I6, I, providing an inlet for lead wires to the interior of said hollow body. A switch for manually Vturning the electric current off and on is indicated 3l, and a thermostat for-controlling .current to the heating lamps .is denoted 32.

Each of the opposite end portions of the elongated base IB of each of the channel members I8 detachably supports a receptacle 33 for a heating lamp 28. The receptacles 33 ca-n be of duplicate construction and .each can be assembled with its corresponding elongated base in the same manner as all of the others. ing lamp receptacle is constituted as an insulating block 34 inside the corresponding channel member and a lamp receiving shell 49 projecting forwardly through Yan opening in the corresponding elongated base. An insulating nut 35, threaded upon the free end portion of an external surface .of each shell and engaged against the forward surface of the corresponding elongated base, retains an annular shoulder of the corresponding insulating block in surrounding relation to the shell .against the interior or rearward surface vof said corresponding elongated base, thus to cause each receptacle to be made rigid vwith the lelongated base by which supported. The insulating nuts 35 are threaded upon external surfaces of the shells, and the heating lamps 26 are threaded in internal surfaces of said shells in customary manner.

An incoming wire 3S .from a `source (not shown) of electrical energy extends to a first fixed contact element .31 of the thermostat 32, a second fixed contact .element of said thermostat is denoted 38, and a movable contact element l39, adapted to bridge the xedrcontact elements 3l and i38, is supported by a bi-metallic strip of the thermostat.

A lead wire 4I extends from the fixed contact element 38 by way of leadwires `42 to each of the heating lamps `28, and lead wires 43 extend from each of said heating lamps to an incoming wire 44. The construction and arrangement will be suchthat the movable contact element 39 will become engaged with the fixed contact elements 3'I and 38 'inresponse to decrease in temperature and disengaged from said fixed As disclosed, each heatl Cil `4 contact elements in response to increase in temperature.

The manually actuable switch 3l includes a fixed Contact element 45, with which the incoming wire 36 is conductively connected by a lead Wire 46, and a movable contact element 4l, conductively connected by a lead wire 48 with the lead wire 4 I.

All of the lead wires to the heating lamps 28 will be situated within the housing provided by the interior surface I'Iand the oblique bounding walls I6, I6 of the hollow body of the heat xture, upon said interior surface, and the channel members are open to said housing across the interior surfaces of the overhanging

flanges

22, 22. Thus Jpassageways for lead wires of the electrical .system to the heating lamps are provided.

The channel members I8 of course are rotatably adjustable in the hollow body of the heat fixture, in the manner as hereinbefore set forth, to the end that heat from the lamps 28 can be directed toward different vlocations of ,a room or space equipped with the .heat fixture which vmay be selected, it being a well 4known fact that more heat emanates directly forwardly from the outer end of a lamp bulb than sideways thereof. The heating lamps 28 are independently adjustable. In Fig. 3 of the drawings, the channel member at the left is at .adjusted position to cause heating lamps when supported thereby to direct their heat vertically downward from the ceiling IU, and the channel member at the right is at adjusted position to cause heating lamps .when supported thereby to direct their heat downwardly ltoward the left. Each of the channel members is capable of adjustment through an arc sufficient in extent to direct heat from lamps supported thereby toward distantly spaced locations of a room -or space having the heat fixture.
