Abstract

160,539. Greenwood, J. H. Dec. 20, 1919. Studio accessories. - Back-ground apparatus comprises several backgrounds carried by rollers a, Figs. 1 and 2, which are mounted on a rotating holder a<2> and normally prevented from unrolling by springs a<5>, Fig. 4. The holder a<2> is rotated by bevel-gearing from the handle f<6> through a gear-wheel a<10> and pinion wheel 6 on a counter shaft E. When the required background is brought into position in alignment with the countershaft E, the wheel e can be moved along the countershaft by a depending handle e<5> and crank arm e<4>, disengaged from the gear a<10> and engaged with the projecting end a' of the selected roller, and the background unrolled from the same handle f<6>. The ends of the rollers a may alternatively carry bevel-gears, and a chain or pulley gearing substituted for the bevel-gearing, provision being made for the countershaft E to engage recesses in the holder a<2>. Reflecting or diffusing screens B, C on spring rollers b are mounted between a frame b<10> and a bracket b<3> secured to the background frame D. Provision is made for a vertical and angular adjustment of the reflector or diffusing-screen.
