The present inventionflrelatesto a floodlight bracket and more particularly to an adjustable floodlight bracket and floodlight combination adapted to be rapidly mountedand adjusted in position to direct light upon the Work in a man her to conform readily todim-Qut regulations in shipyards, airplane manufacturing plants; and other manufacturing plants, particularly those engaged'in the production of'war materials r quiring substantially continuous production. j
' In large-scale manufacturing operations, as in the building of ships, in which'continuousoper 'ation is required, it is impracticaltomaintain' the required illumination throughout a plant tog'eth-y er with provision for f blackouts or to'conform .to dim-out'regulations, and the provision of sufficient illumination with the necessity of shifting the location of the work to provide for the carrying out of subsequent operations, after each operation has'been completed, has been not only difficult, but time consuming, resulting in a slow down of operations. Q One of the objects light combination which'm'ay be readily mounted upon fixed objects which are generally'available in manufacturing plants, such assupporting col- 'uinns, beams, and the "like, and which may be g of thepresentinventionis to provide a form "of floodlight support and floodfinal' clamping or adjusting means having lever means for app ying a high tightening force in the final secured position, so as to prevent any I accidental displacement of the bracket.
Referring more in'detail' to the drawing, the numeral 2 designates the adjustable floodlight readily carried ortransported from one location to another in a plant, factory or other building in which it is to be used. 1 I g I Anotherobject of the invention is to provide a form of floodlight support and floodlight comthe direction of illumination'inboth a; vertical and horizontal plane, so' that, as theworlk' is binatlon which may be rigidly fixed in a desired position upon a column, beam'or other support 35 shifted in position or turned, the direction of the light maybe accordingly changed to provide the desired path of illumination. I if Another object of the invention is to" provide a form of fio'odlight bracket which is'simple'in operation and rugged in construction so that it may be operated and used by substantially any class of help, whetherjskilled or unskilled, and which may be manufactured at a relatively low cost of production. f i j p [Another object of the'inventidn'is to provide a form of floodlight bracket upon which a floodlight maybe readily. mounted infadjustable position and which is provided with mounting 'ineans' adapted to be readily moved into fthedesired approximate position f or fitting. approximately a column or beam of anyordinary size and with 1 The invention I ,With' 'these and other objects in View, the invention comprises the various features hereinafter mor'e fully explained and defined in the annexed claims. I

bracket of the invention as a' whole and the numeral 4 designatesthe adjustable floodlight or lighting fixture. I
, The fioodlight bracket inits preferred form comprises a main frame member or portion 6, in the form of .an angle iron having the main frame extension 8' and a short arm member I!) trarisversej'thereto, or in other words, bent at right angles to the main frame portion. Connected to the outer side of the main frame portion 8 and preferably welded thereto, is a proj'ection or bass member l2 having an opening '14 therein in which the flo odlight or lighting fixture may be mounted and fixed in adjustable position. t
In order to provide means for obtaining an approximate fit on thecolumn or beam on which the fioodlight bracket is to be mounted, so that ti-relatively slight movement of parts will sufiice 'tdlbrin'g the supporting members into holding engagement with the column or beam, a movable or slidable arm member 28 bent in the form of an angle iron, and having a part 30 adapted for sliding engagementwith the under side of the main frame'portion' 8, and a transverse part 32 atrightangles thereto are employed, which are adapted to cooperate with the arm member 10' and the support 48 in the manner hereinafter described, In order to obtain the approximate fit,'a'series of notches.l6,'|8, 20,22 and 24 are provided along one edge 9 of the main portion 8, preferably the upper edge when the bracket isv mounted-with the lever member 46 to the right-as shown in Fig. 1; Pivotally mounted on thetransverse part 32 isa bar member or pawl frame, lateral extensions 38 and 44 may be bent around the main frame'member 8, so that the part 32 may be moved backward and forward over the under surface of the said member. It will be understood'that'a sepafi fitegririg' member might be used forthi's purpose, although the construction illustrated is simpler in operation and constructional features. In order to hold me position, the end 2! of the pawl or pin member 'onto the upper side of the nipple so as to hold the nipple in place in the said opening. The 45 degree elbow 60 is then screwed into place on the upper or exposed end of the nipple 54, so that the elbow is turned outwardly from the bracket as .shown in Fig. 1 of the drawing. Another nipple B2 is then screwed into the upper end of the elbow or 45 degree pipe fitting 60, and

depending on the nature of the operation re-' quired on the work. It is to be understood, also, that in place of the handle 46 as shown, a crank having a handle extension at right angles to the extension 46 might be used, and other similar modifications may obviously be made by those skilled in the art in other parts of the structure of my invention without departing from the scope of the invention as defined. As illustrated in the drawing, and as above described, the locking bar 26 is preferably pivotally mounted on the inside of the transverse member 32, so as to be adjacent the beam or timber to which the floodlight bracket is to be attached. It has been found by experiment that there is more danger of the locking bar 25 being dislodged or broken off if it is mounted on the outside of the transverse member 32, or away from the beam or timber on which the bracket is mounted. It is to be understood that the locking bar is only a safety feature, as the flood-light bracket locks itself on any beam which is four inches or more in thickness. In the ordinary dimensions of the fioodlight bracket, the locking bar may be only an inch and a half long, and in its hinged position on the transverse jaw member 32, it gives an inch and three quarters clearance to the points 34 and 3B of the jaw. In the same size bracket, the locking bar may be made an inch long so as to give an additional half inch clearance from the points 34 and 36, or other suitable dimensions may be used as will be obvious to those skilled in the art. It is to be understood that I do not desire to be limited to definite dimensions or proportions except as defined by the claim annexed hereto.
Having thus described the invention, what is claimed as new is:
A fioodlight and fioodlight bracket combination adapted for use in structures subject to dimout regulations which comprises an angle-bracket frame member having a longitudinally extending body portion and a fixed transverse jaw portion, a series of spaced indentations along one lateral edge of the main body portion, a movable transverse jaw member slidably mounted on said body portion, a locking member adapted to cooperate with said indentations for locking the said transverse 'aw member in a fixed position relative to the body member, said locking member being pivotally mounted at one end thereof on one face of said slidable transverse jaw member for movement into and out of engaging relation with said indentations, a screw member mounted on said fixed jaw portion for movementat rightangles thereto for locking the bracket in position, a lever connected to said screw member for screwing and unscrewing the same, swivel mounting means connected to said angle bracket frame member, and a fioodlight connected to said swivel mounting means, said swivel mounting means including an elbow mounting member having threaded portions thereon and locknuts fitting the said threaded portions for locking the fioodlight in a fixed angular'position with respect to the body portion of the bracket.
