REFLECTOR SUPPORT Filed April '7, 1951 INVENTOR g J R Luder ATTORNEYS Patented Nov. 22, 1932 UNITED STATES CHARLES E. LUDEB, QF WASHINGTON, INDIANA REFLECTOR SUPPORT Application filed April 7, 1931. Serial No. 528,375.

This invention relates to portable reflector supports for use in photography and, among other objects, aims to, provide improved supporting brackets for flash-lamp reflectors having novel means to lfacilitate easy attachment to and removal from a stand and means whereby the reflectors may be used inter changeably and quickly adjusted to focus the lightin any direction. ,l

Other aims and advantages of the invention will appear in the specification, when conf sidered in connection with the accompanying drawing, wherein I Fig. 1 isa rear elevationof a pair of reflectors supported on a tubularstandby the preferred V,form of brackets;

Since the advent of electric, photo-flash lamps, there has developed a need for a portable and adjustable support whereby a .pho-` tographer can quickly set up and adjust the apparatus so as to get the best exposure. This invention, therefore, aims to provide improved supporting means whereby one or two reflectors may be quickly mounted and adjusted on an ordinary collapsible stand.

In the accompanying drawing, the supporting stand is shown as comprising a col lapsible tripod 10 having a standard composed of telescoping, tubular sections 11 adapted to be held adjusted by means of set screws 12. In Fig 1, the tripod stand is shown as supporting a pair of reflectors 13, each of which carries a lamp socket (not shown) and electric plugs 14 on a lamp cord 15 are removably connected to the sockets. The lamp cord may be plugged into an ordinary lamp or a floor socket and the stand moved to any convenient location.

The two reflectors 13 are shown as being re- .crescent-shaped, sheet metal bracket/*2.0, se-

`Vdesigned as to bring the center of gravity of single reflector may be adjustedon the stand movably mounted on theopposite ends ofra v' cross-arm 16, .preferably made of a flat tube having angularly bent ends 17. To the center of this cross-arm is secured a tapered pin 18 which preferably projects through holes in ,5

the tube 16 and is fastened thereto by means of nuts 19.- See Fig. 3. j However, the pin may be welded or otherwise secured to the cross-arm. In this example, the tapered part of the pin is non-circular, conveniently being hexagonal in cross section, so as to? present side edges which will wedgev against the inner wall of the tubular standard 11 and pre- V vent accidental turning of the ref lectoria-fter `the cross-arm is adjusted. `The tapered pin permits the cross-arm lto be inserted'and removed very easily'p` t Each of the refleotorsis show-n ashaving a cured toits rear wall below 'thel center and flange`21` to which is secureda tapered hexagonal pin 22'by means-of jamb nuts 23'. The pins 22 are of the same sizeasthe pin 18 and are adapted to'be` insertedv and properly adjusted in verticaliholes or openings vthrough the cross-arm, as shown in Fig. 4:. The angularly bent ends 17 of the cross-arm are so the cross-arm Aand supported reflectorsover the upperend of the tubular standard, so that the assembly over. Y

When itis desired to use-,only one reflector or flash-lamp unit on 'the stand, the cross-arm is stable andnot readily toppled standard 11, as shown in Fig 6. Thus, the

so as to concentrate the light in the desired direction. Since the reflectors are removable, and are interchangeable with each other, as

, well as with the cross-arm or bracket, a dou-l ble-unit outfit can easily be converted into a single unit. l, Y

From the foregoing description, it will be seen that the improved reflector supporting "attachments can be made at a small cost.` lThe improvedmounting permits instant adv justment of the reflectors without-'using seteach bracket has' a rearwardly lprojecting Y W may beomitted and the tapered pin 22 of a rey flector inserted in the open end of the tubular screws or other fastening elements on the brackets. Moreover, the non-circular ins on the cross-arm and the reflector brac ets prevent accidentally turning the reflectors out r of adjustment. The parts may be quickly set up and dismantled. Further, the parts can be stored in a relatively small box or container so that the outfit can easily be carried as a part of a photographers equipment. y Y Y Obviously, the present invention is not restricted to the particular embodiment thereof herein shown andk described. Moreover, it is not indispensable that all the features of' may be employed advantageously in various combinations and sub-combinations.
