Abstract: 1,117,963. Cooling and conveying metal sheets. SCHLOEMANN A.G. 12 Aug., 1966 [3 Sept., 1965; 8 Feb., 1966], No. 36129/66. Heading B8A. A conveyer bed for cooling and conveying metal sheets comprises stationary, spaced support members (4), Fig. 2 (not shown) and movable support members 5. The movable members are carried on girders 6, 7 and balls 9 provide for relative movement between'the girders 7 and longitudinal supports 10. The latter, due to inclined guides 13 are raised and lowered when the supports 10 are reciprocated, via linkage 20-22, by a motor driven crank-shaft 23. The girders 7 are reciprocated by a motordriven shaft 19. In use, after a sheet has been fed on to the support members 4, 5 the supports 10 are moved to their extreme right-hand position, drive to the shaft 23 being automatically switched off and a brake actuated. With the supports 10 in this position the support members 5 are at their highest point. The shaft 19 is next rotated until the members 5 have been moved to their extreme left-hand position when the drive is out off and braked. By further sequential operation of the shafts 23, 19 the members 5 are lowered and returned to their original position. The cycle is completed by rotation of the shaft 23 to an intermediate position so that the members 5 lie in the same plane as the support members 4. Lifting of the sheet recommences from this position and shock, both to the sheet and the conveyer, is minimized. Support during cooling is also improved. In a modification (Fig. 3, not shown), the girders and longitudinal supports are in two parts (7a, 7b; 10a, 10b) and a link (25) connects the parts (7a, 7b).

Abstract: 784,667. Spring winding mechanisms. STAMFORD METALLICS, Ltd. Dec. 16, 1955, No. 36184/55. Class 10. The spring 3 of a toy motor car is wound by pulling a cord 15 which in the spring unwound position shown is wrapped around a drum 9. The drum is freely mounted, along with discs 13, 12, 11 on the winding spindle of the spring whilst a disc 10 is fixedly attached to the spindle. The discs 13, 12, 11, 10 are provided with respective lugs 13a, 12a, 11a, 10a, the lugs 12a, 11a, 10a being bent into the rotational paths of lugs 13a, 12a, 11a respectively whilst the lug 13a is upright and in the path of a lug 14 fixedly attached to the drum. Drive from the spring to the rear axle of the toy is through clutch 5, gear wheel 4 and transmission 7, 6, 8. Pulling the cord 15 effects clockwise rotation of the drum 9 and, through interengagement of lugs 14, 13a, 12a, 11a, 10a, rotation of the spindle 2. Three revolutions of the drum fully winds the spring 3 and loads a spring 17 which, by its connection to drum and spring frame 1 effects, on release of the cord, re-winding of the latter around the drum. Three anti-clockwise revolutions of the drum are possible for this purpose as the drum and disc 13 move through one revolution before lug 13a abuts lug 12a, the drum and discs 13 and 12 move through a further revolution before lug 12a abuts lug 11a, and, finally drum 9 and discs 13, 12 and 11 move through a third revolution before the cord rewinding movement is arrested by the abutting of lugs 11a and 10a. On release of the spring 3 the spindle 2 moves through three anti-clockwise revolutions and causes, thereby, the discs 13, 12, 11 and 10 to once again take up the positions shown. The number of discs used may be varied depending upon the number of revolutions of the spindle 2 required to fully wind the spring 3.

Abstract: 436,183. Suspending flexible lampshades. MIETHKE, W., 22, N³rnbergerstrasse, Lichtenrade, Berlin. Dec. 18, 1934, No. 36262. [Class 75 (ii)] A bowl-shaped lampshade made of flexible transparent or translucent material such as paper, starched fabrics, celluloid, cellulose esters, or synthetic materials, is suspended under a source of light in such a manner that the area of the freely suspended surfaces of the shade between the power vectors formed in the bowl of the shade through the suspension is reduced as compared with the area involved with the usual three-point suspension, so as to reduce deformation, particularly at the edge of the shade. For this purpose the number of power vectors may be increased, or the area under the power vectors may be reduced. Fig. 1 shows a shade bowl 2 suspended by seven wires or cords 4<a>-4<g> from a central point 5, thereby producing a corresponding number of power vectors 1. Fig. 2 shows the use of a ring 6 to provide an infinite number of points of suspension. Fig. 3 shows suspension members 7<a>-7<c> engaging the bowl at points intermediate its edge and its centre. Fig. 4 shows a shade suspended at a single point 8 by means of a wire clip 9 engaging the holder of an incandescent bulb 10 or above it.

Abstract: 506,631. Eccentrics. FAIRWEATHER W. C. (Singer Manufacturing Co.). Dec. 21, 1938, No. 37104. [Class 122 (i)] [Also in Groups VII and XXV] Co-operating parts of a sewing-machine are actuated by two adjustable eccentrics which are connected together for simultaneous adjustment by a single means. A disc 21 fixed to the shaft 20 by set-screws 20<1> has pivoted to it at 221 on one face a plate 22 formed with one eccentric 23 and at 26 on the other face a plate 27 formed with the other eccentric 28; the eccentric rods 183, 184 are omitted in Fig. 6. The plates 22, 27 are slotted at their centres so that they can swing about their pivots 221, 26 across the shaft 20 to vary the throw of the eccentrics, and are held against the disc 21 by pins and slots 24, 29 respectively. A link 44, cranked to pass through a large notch in the disc 21, and recessed into the faces of the disc 21 at its ends, is pivoted to the plate 22 at 45 and to the plate 27 at 46, so that the plates are forced to move in unison about their pivots and the throws of the eccentrics are adjusted simultaneously and equally. The plate 22 is pressed towards the position in which the throw of the eccentric 23 is zero by a spring-pressed pin 41 bearing against the shaft 20, the movement being limited by a stop-screw 39 ; the plate 27 is similarly pressed towards the zerothrow position by a spring-pressed pin 36, but the stop-screw 33 in this case passes through a hole in the shaft 20 to abut against the bevelled end of a pin 49 sliding in an axial bore in the shaft and secured to an adjusting screw 53, whereby the throw of both eccentrics is determined. The pin 49 is prevented from rotation in the shaft by a screw 51 engaging a slot ; a leaf-spring 55 secured to the screw 53 holds this screw frictionally in its adjusted position.
