Abstract: 18,535. Quincey, S., and Harrison, C. Aug. 27. Developing; fixing ; roller slides.- Attachments are described d more especially for use with apparatus described in Specifications No. 12,371, A.D. 1899, and No. 15,551, A.D. 1900, which provides means whereby a photographic film may be exposed, developed, and finished without a dark room. The carrier 1, Fig. 2, has grooves by which it fits on to an ordinary camera, and the endless roller blind 2 passing over guiderollers 3, 4 has an opening at one part, and is drawn over the rollers by cords 7, 7<a>. A sliding shutter 8 may be used as well or alone as at 16 in the modified form shown in Fig. 5. A mask 18 held in a seating 17 by a spring is provided for plates or flat films. The roll film 22 and its backing-paper 22<a> is guided over the roller 20 by the curved metal strip 56, and between the rollers 21, 21<a>, through the slot 24 in the carrier and the coincident slot 27 of the film receptacle 26, 25 by means of the pivoted guide-plate 30. The receptacle for the film is formed of two parts 25, 26, the former fitting on to the carrier directly, and the latter fitting on to the part 25 as a light-tight cover. The roll film is contained on a spool b in a holder formed of two parts 37, 38 which is attached on to a metal plate seating 31 provided with a slot 32 in register with the slot 23 in the carrier. The part 38 has two extensions which engage slots in the plate 31 and in the bolts 33, by which it is firmly locked in position. The film is guided through the slots 39, 32, and 23 by the pivoted guide plate 47<a> held in position by the spring 51. Just below and inside the feed slot 39 is a pivoted plate covered with padding 53 and held in position by the spring 54 so as to close the slot and make the holder light-tight when detached. In Fig. 5, a leading strip of silk is wound round the spool 60 and is led over the guiding-strip 56 and wound on the lower spool 60". It has an opening of sufficient size to uncover the part of the film in the carrier opposite the opening in the mask 18. After exposure the film is rewound on the holder 37, 33, and the latter is then detached from the carrier and attached to the developing and hardening box 65, Fig. 11, being locked on to the latter by the catch 73 of a wire-spring frame 72. The latter frame also carries a roll of padding 76 which closes the slot 67 when the holder 37, 38 is detached. To prevent the film curling, it is guided by wire guides 78 pivoted on a plate 80 which also carries a flexible strip 81 to close the slot 67. The backing-paper 22<a> on the film passes through the slot 77 left between the bottom plate of the film holder and the end plate 66 of the developing-box. The front part of the box has a view lens 83 with a spring shutter 84, and the back has a transparent sheet 85 of non-actinic material. After developing one length a thin knife is inserted between the backing-paper and the plate 66 to sever that portion of the film from the roll. In the modification shown in Fig. 14 the film holder is attached to the front of the box 65. The extensions 40 in the part 38 engage notches in two side bolts 92, Fig. 13, coinciding with notches in the covering plate 90. By pulling the crossbar 93 down, the shutter 93<a> attached thereto uncovers the slot 88 in the box and the bolts 92 are pulled down to lock the bolder. Also at the same time by means of connecting-levers 95, 96, 97, and 99 the guide-sheaths 100 are brought into position near the feed slot 88 to receive the film, and the backing-paper is drawn off through the slot 102 left between the plate 90 and the part 37.
