Specification of Letters Patent. Patented Sept. 1'7, 1918- Application filed February 15, 1917. Serial No. 148,890.

To all whom it may concern:

Be 1t known that I, BEN Pnmus, a citizen of the United States, residing at Lakewood,

- in the county of Cuyahoga and State of lapsed or dismantled and reassembled with equal facility. Other objects will appear in the appended description.

Referring to the drawings:

Figure 1 is a front View of the cabinet.

Fig. 2 is a side view of the cabinet.

Fig. 3 is a section taken on the line A-A of Fig. 1.

Fig. 4 is a section of the cabinet taken on the line BB of Fig. 2.

The cabinet consists of a reflecting back 1 and a collapsible hood or front portion 2. The back 1 may have various shapes but it is preferably made of stamped sheet metal having the upper portion 3 of curved contour as indicated in Fig. 4. The lower part of the curved portion merges more or less gradually into the lower portion 4 with which it makes an angle at the junction point 5. The lower portion 4 referred to is substantially a plane surface excepting that it has curved portions 5 and 5 (Fig. 4) at the sides and its purpose is to reflect the light outwardly against the diffusing screen referred to later.

The front portion 2 consists of a rectangular window frame made up of four strips 6, '7, 8 and 9 preferably made of some light material such as wood and mortised or otherwise securely joined together at the corners where braces 10 may be added to increase the rigidity.

The window frame has secured thereto two thin strips of wood 11 and 12 somewhat narrower than the portions 6, 7, 8 and 9 to which are secured strips 13 and 14 to form slots 16 and 17 at each side of the frame, which are adapted to receive the diffusing curtain or screen. Fabric 18, 19 and 20, or other flexible material, is secured to the sides 6, 8, and the be pushed upward or broken? top 9 of the frame in any way, preferably by tacking it thereto by means of thin strips 21} Th back portion of the flexible fabric is secured to additional strips 22, 23 and 24 (Figs. 3 and 4) which in turn are bolted or otherwise secured tothe sheet metal back 1..

The bottom of the cabinet is closedby a rigid member 25 secured to the lower portion 40f the sheet metal back. The front frame of the cabinet may be hinged to the bottom member 25 by any means such as hinges 26, 27 which are secured to the frame and bottom member respectively as shown. Hook shaped member-s28 and 29 are secured to the bottom 25 and are adapted to fit over the frame as described later.

A diffusing screen 31 is arranged to slide in the slots or ways 16 (Figs. 1 and'4) and for convenience this screen is mounted on the spring roller 32 revolving in brackets 33 and 34 which are secured to the upper part of the wooden frame.

The upper part of the back portion 3 is closed by a top member 35 which may be conveniently made of sheet metal. This top portion has an opening to permit the insertion and suspension of the lighting unit 36 which by way of exampleis shown as a flaming arc lamp. f.

At each'side of the collapsible portion a toggle brace 36 is arranged to hold itin extended position. WVhenever it is desired to collapse the front portion this toggle will Also the hood portioncan be held in any intermediate positiomone such, position being shown in dotted lines in Fig. 2, to throw the light in a more horizontal direction. When the hood is completely collapsed the secondary source of light, "in. the diffusing screen, will be in substantially a vertical plane. The hood may be locked in any of the intermediate positions by tightening up on thumb nut 37 of the toggle joint.

The box or inelosed portion of the cabinet is suspended from a standard by means of two hooks 37. 38 secured to the top portion The supporting standard referred to may be made in various ways, but it is conveniently constructed of gas or water pipe of about 13, size. It consists of two upright members 39 and 40 threaded into Us 43, 44 which are joined by a pipe 45 adapted to receive the hooks 37 and 38 previously referred to and also to support the are lamp or lighting unit 36. Two pipes 46 and +26 are threaded into the Ts i1 and l7 at the top and at the bottom into additional Ts i8 and 49 which likewise receive pipes 50 and 51 on the one hand, and 52 and 53 on the other. A cross pipe 5% is secured to the Ts 41 and 42* and is adapted to receive the hook shaped members 28 and 29 previously referred to.

The lighting cabinet is preferably painted or coated throughout on the inside with good light reflecting material so as to reflect the light against the diffusing screen 31which is drawn down toclose-the front part of the frame when the cabinet is being used. 7

By tilting the window forwardly the light is thrown downwardly on the object tobe illuminated in the most favorable direction. The light proceeding downwardly from the lampisthrown outwardly on the screen by forwardly and downwardly inclining the plane portion a. The curved upperportion of the back cooperates with the other reflecting surfaces in uniformly illuminating the diffusing screen.

Whenever the lighting cabinet is to be shipped or is to be moved from one room into another it can be very readily dismantled by lifting the supporting hooks off of the pipe members 4:5 and 5e, and the front portion collapsed by pushing upward on the toggle braces 36. The box portion of the cabinet can thus be collapsed into a small enough space to be readily transported through small doors or shipped Without inconvenience.

The supporting standard of the apparatus can be readily placed in shape for moving or storing by grasping the pipes 51, 53 and revolving the Ts secured thereto around the pipes 46 and et6 until the horizontal pipes of the frame are swung more or less into the plane of the vertical members of the standard. 1

The lighting cabinet can be readily reassembled and placed in condition for use by reversing the steps just described.

Having described mv invention, what I claim is:

1. In lighting apparatus, the combination of a frame adapted to support'a diffusing screen, a reflecting back hinged to said frame, said back having a curved upper portion, a source of light located adjacent the curved upper portion, a flat forwardly inclined, lower portion adapted to, reflect light on the diffusing screen and flexible sides and topattached tosaid frame and back to form an inclosure therewith.

V 2. In lighting. apparatus, a base, a pair of vertical standardsattaehed theretoand upper and lower bars connecting the vertical standards to; form, a supporting frame, a reflecting back adaptedto be suspended from the frame, a difl'using screen hinged to. said back and collapsible sides and top attached to said reflecting back and diffusing screen and adapted to form aniuclosure therewith.

3. Inlighting apparatus, a, base, a pair of vertical: standards and upper and lower horizontal bars connecting the vertical standardsto form a supporting frame, a reflectin back having a rigid upper member, sai member havingv an opening therein for admitting a source of light, ajpair of hooksattached to the member for suspending the back from said upper horizontal bar, a second pair of hooks attached to the bottom of the reflecting back and adapted to fit on the lower horizontal bar, a diffusing screen hinged to the back and collapsible sides and top fastened between the reflecting back and diffusing screen to form an inclosure-for said source of light.

In testimony whereof, I hereunto, afiix my signature.

BEN PERRIS.
