"This invention relates'to a new and improved supporting structure and more particularly toa structure for supporting apparatus hung from a ceiling or from cross joists of a building.
" It hasfbeen found desirable in many instances to support heavy structures from the ceilings of buildings, such structures for example, as heating and Ventilating apparatus. Such apparatus may comprise unit heaters, radiators, blowers or the like".-`V While my improved supporting structure will support apparatus of this character it will "be understood that the invention is independent ofthe particular form of apparatus which it is tolsupilort. l i
Ajnumber of `methods have been used heretofore to supportv apparatus of this character in rooms or areas to be heated. In general such `methods include the use of'comparatively heavy supporting timber which are bolted to ceiling beams or secured to the beams by hooks which are hooked over the ceiling beams. These structures generally are unsightly and do not admit of adjustment of the location of the supported apparatus. ^In many cases after the apparatus, such as a unit heater, has been suspended from the fceiling it will be found that the angle at which itis placed does not properly distribute or direct the-heat. With usual types of suspensions it is necessary to take down the supporting structure t change the position of the heater. This causes l additional injury to the ceiling in finished rooms and also requires additional labor expense.
` Itis an object of the present invention to provide a new and improved supporting structure for suspending apparatus from ceiling beams or the like.
It is an additional object to provide a structure E in standard form which is adapted for use with f different spacings and sizes of supporting beams and with different sizes of apparatus to'be supl ported. `It is also an object to provide a device which `mayrbe quickly installed and which results in a minimum of injury `to a ceiling.
It is a further object to provide a device which is capable of adjustment of the supported structure without movement of the structure secured apparatus while it is being secured to the permanent supporting structure.
It is a further object to provide a device which is simple in design, composed of but few parts, and adapted for commercial production and installation. l Y v Other and further objects will appear as the description proceeds.
I have shown a preferred embodiment of my invention in the accompanying drawings in whichi Figure l is an elevation showing my improved device supporting a heater or the like;
FigureZ is a horizontal section taken on line 2-2 of Figure 1; I
Figure 3 is a cross section taken on line 3-3 of Figure 2.
Figure 4 is a section on an enlarged scale, taken on line 4--4 of Figure 2;
Figure 5 is a section on an enlarged scale,r taken on line 5--5 of Figure 2; and
Figure 6 is a section on an enlarged scale, taken on line 6-6 of Figure 2.
In thedrawings, the joists I I support a ceiling construction I2, which may consist of lath and' :i
plaster, metal wall board or other material. The hanger hooks I3 have hooked ends extending over the topsof the joists and have threaded lower ends on which are placed the nuts It, supporting heavy washers I5. The washers I5 support the" spaced UA bars I6 which are spaced by the tubular members I1 which t on the tie bolts I8. This assembly of U bars, spacing members and tie bolts comprises the upper or iixed frame which is supported and positively secured to the ceilingA by the hanger hooks I3.
v`The tie plate I9 extends across between the lower legs of the U bars I6 and supports the bolt 20, which in turn supports the lower tie plate 2|. This lower tie plate 2l fits Yunder the. Aupper legs of the U bars 22, which, with the spacers 23 and tie bolts 24, form the lower or movable frame. I
The lower legs of the U bars 22 support the floor flanges 25 into which are threaded the upper ends of the pipe hangers 26. As shown in Figure 1, the lower ends of the pipe hangers 26 are connected by couplings 21 to the upper endsV of the support pipes 28 of the unit heater 29.
The canopy 30 is designed to cover both the upper and lower frames regardless of their relative angular position. The canopy is supported by and moves with the lower or movable frame. As shown in Figure 2 the canopy is an elongated Octagon but it may obviously be made in other shapes if desired. It must have a width greater than the upper or xed frame and a length greater than the lower or movable frame. It is formed with sides 3| which engage the ceiling I2. The angle members 32 are secured to the inner face of the canopy 30, as shown in Figures 1 and 2, by spot welding or in any other desired manner. The strap 33 passes over the lower frame and is secured to the angles 32 by the bolts 34. Openings 35 are formed in the sides 3| of the canopy 30 so that the bolts 34 may be adjusted to tighten the strap 33 and bring the edges of the sides 3| of the canopy tightly against the ceiling |2. K
As shown in Figure 2, the canopy 30 may have two sets of spaced openings 36 and 3]. As shown in the drawings, the pipe hangers r26 pass through the outer set of openings 31. The swinging cover plates 38 are formed in pairs and are sodisposedl as to cover the unused openings. These plates 38 are pivoted on screws or bolts 39 and may be readily removed and reversed in position if the other pair of openings 36 is tobe used. It will be apparent that the floor flanges 25 may be slid back and forth as desired, and thus the supporti ing structure and canopy shown may be used for two standard spacings of pipe hangers v2|i in connection with two standard sizes of space heaters or the like. The lock nuts v4|] engage the `undersides of the cover plates 38 and assist in supporting the canopy 30.
It is believed that the method of assembling and using the supporting device will be apparent from the drawings and the description. The hanger hooks |3 are used where it is practical to have the hooks pass over the upper side of the supporting beams, butit will .be understood that other usual types of securing means may be substituted. Where the beams carry a oor upon their upper sides, the hooks maypass through the beams, or screws or other standard securing and supporting membersmay be substituted for Y hooks. It will be apparent that these supporting means may be spaced at any desired distance apart within the limits ofthe lengthof the upper supporting frame. Consequently, the device may be supported from beams of any spacing within that limit. Obviously also the upper and lower supporting frames may be made of any size to correspond to any beam spacing and any necessary spacing of supporting members.
The upper supporting frame is preferably placed at right angles to the line of direction of the beams and in order to secure it in place it is only necessary to make holes through lthe plaster angle with the upperframe and Vclamped firmly rin place by tightening up the bolt 20.
If a canopy is to be used, the canopy is slipped upwardlyover the pipe hangers 26 and the lock n uts 31 screwed up to hold the canopy in place. The strap 33 is placed over the lower supporting frame and may be tightened up by the screws 32 so as to bring the edges of the canopy rmly against the ceiling. In case it is desired to change the angular adjustment of the lower frame relative to the upper frame, the ,canopy may be readily dropped down soA that the bolt 20 may be loosened. It may be possible also to swing the lower frame without loosening this bolt, as sufcient leverage is afforded by Athe widely spaced pipe hangers 26 Vso that the frictional grip of the washers |9 and 2| may be overcome without loosening the bolt 2|).
The various parts may be made in different sizes to suit different weights and shapes of apparatus to be supported and I contemplate such `.changes and modifications as come within the spirit and scope of the appended claims.

Supporting .apparatus comprising elongated upper and lower frame members, each frame comprising spaced inwardly facing `U-.shaped membersheld in place by spacing connecting members, means .adjustably connecting the two members, connecting means having portions slidable between the U-shaped members of .the upper frame and having upwardly extending portions for connecting .the upper frame .to a
supporting structure, and means for connecting a `device to be supported to thelower frame.
2. Supporting apparatus comprising elongated upper and lower frame members, each Aframe comprising spaced inwardly facing U-shaped members held in place by spacing connecting members, means adjustably connecting the .two members, connecting means lhaving portionsslldable between the U-shaped .members of the upper frame and' having upwardly extending portions for connecting the upper frame to a Ysupporting structure, and supporting means having portions slidable between the U-shaped members of the lower frame and having downwardly' extending portions for supporting a device below the lower frame.
.3. In combination with supporting apparatus comprising relatively movable upper andlower frames, means adjustably connecting the' two members, means for securing the upper 'frame `to ceiling .beams or theilike, a. canopy for covering said frames, means connected to the .canopy and passing over the lower frame for securing the canopy to the lower frame and urging the edges of the canopy toward the ceiling beams or the like.
4. In combination with supporting apparatus, comprising relatively movable upper and lower frames, means adjustably connecting said frames, a canopy for covering said frames, means for securing the canopy to the lower frame, supporting members extending downwardly from the lower frame, a pluralityof spaced openings in the canopy, certain of saidy openings serving Vto permit passage of the supporting means, and'adjustable means for closing `theopenings not used by the'supporting'means.
