Abstract: 238,031. Rose, W., and Rose Bros. (Gainsborough), Ltd. May 31, 1924. Packeting by wrapping-up. - Relates to wrapping-machinery and to means whereby the wrapper feed is interrupted when an article is not fed to the wrapping position. An arm 25, Fig. 3, carrying a hinged feeler 23, pivoted at 26 to a bracket 27, is actuated by links 32, 35, roller 45 and cam 46 to oscillate between positions A, B if no article is present at the wrapping position. A bolt 39, Fig. 2. is mounted to slide in a guide 40 and is actuated by an arm 42 adapted to be engaged by tappets 30, 31 on an extension 28 of the arm 25. If no article 43 is present at the wrapping position, the bolt is drawn down below the level at which a detector arm 49 is periodically moved by a spring 62 against a cam 54. The arm is free to move so that a finger piece 60 acts on a clutch lever 57 to disconnect clutches 18, 20 against the action of a spring 59, and thus throws the wrapper feeding rolls 1, 10 out of gear. If an article is present, the arm 25 is arrested below the position B, the bolt 39 is not withdrawn and prevents thedetector 49 and piece 60 from acting on the clutch arm 57, and the clutches 18, 20 continue in gear.

Abstract: 455,774. Photographic exposure meters. RISZDORFER, O., 1, Gellerthegy - utca, Ungarn, Budapest. March 18, 1935, No. 13413/36. Convention date, March 16, 1934. Divided out of 453,845. [Class 98 (i)] In a photo-electric meter, the amount of light falling on the cell is regulated by the diaphragm of the objective lens, and the electrical current of the cell is regulated in accordance with at least one other variable factor. The cell 62, Fig. 1, is mounted behind the objective lens 59 on a shaft 70, the bent end 71 of which is connected with the shutter release lever 61. A contact on the shutterspeed disc 60 moves over a resistance 57 in the circuit of the photo-electric cell, which also includes a measuring instrument coil 65 with a pointer 66. In determining the exposure, the shutter speed is regulated until the pointer 66 is restored to its zero position, and upon actuation of the release lever, the cell 62 is swung away from the lens axis. In the form shown in Fig. 3, the shutter speed control is connected to a ring 80 which has a wedgeshaped member engaging a stop 79 to vary the inclination of a series of adjustable flaps 75 in front of the cell. The flaps are pivoted on the framework 73 of the cell by rotatable pivots, the extensions 76 of which are connected to an adjustable ring 77 bearing the stop 79. The photo-electric cell and control device are fixed on a shaft 84 so that they can be swung out of position. In the form shown in Fig. 5, the photo-electric cell is made in two halves 88, 89, mounted on a shaft 90 and connected to the shutter-speed ring 94 by connecting rods 92, 93. The adjusting ring 96 engages the ring 94 by a wedge-shaped peg 95 so that the inclination of the cells can be adjusted. Other factors influencing exposure can be taken into account by applying light filters.
