Abstract: 246,293. McDonald, L. R. Jan. 3, 1925. Sheets and like elements, travelling. - In apparatus for displaying independent flexible placards wherein means are provided for shifting, as by screws 4, 5, raising, as by cams 6, 7, transferring from rear to front, as by rollers 26-32 and belts 25, and lowering the placards successively into display position, the top of the exhibited placard is prevented from falling back immediately on to the pack 3 as the lower edge is gradually lowered to the shifting means. As shown, a worm 69, driven by a shaft 62 carrying a pinion engaging an endless chain forming part of the drive for the belt rollers 35, 38, is adapted to engage the upper edge of the displayed placard so as to allow it to fall back against the pack 3 when a new placard has been lowered into view. A placard on reaching the front is directed by guides 50, 51 and is received on a flanged crosshead 52 carried on a bar 54, 56 pivoted at 55. The end 56 bears against the cam 6 and as the cam rises the cross-head 52 drops and lowers the placard gently on to the smooth portions of the screws 4, 5. The rear placard is assisted in rising against the friction of the leaning pack by a rubber or like roller 72 continuously rotated by a sprocket engaging one of the drive chains. Dovetailed recesses in the lower edges of the placards are engaged by detaining means 19 which prevents all but the rearmost placard from rising. The detent 19 is preferably tapered at 20, and) is slidably held in a support to which it is detachably connected by a spring 22. To facilitate access to the placards the transferring and reversing means comprising the belts 25 and the system of rollers associated therewith, together with the worm 69, are mounted as one unit hinged to the main device about the shaft 43 of the roller 35.

Abstract: 620,093. Placing packing-rings on stoppers. RICHARDS, S. I., and WILLSON, C. R. Jan. 3, 1947, No. 306. [Class 125(iii)] In a machine for applying resilient rings to stopper shanks, a continuously rotated body or table carries a ring-applying finger assembly successively into operative relation with a ring-supplying device, a stopper-supplying device, and an endwise abutment to resist endwise displacement of stoppers whilst rings are applied thereto, and the stoppers are ejected automatically after rings have been applied to them. As shown a finger assembly is carried round on a rotary table 19 until a pillar 25 removes a rubber ring R from the bottom of a chute 41, the ring dropping into position around the tips of fingers 26 (position (a), Fig. 3). During further movement of the assembly, stationary cam tracks 32, 30 cause pillar 25 to be lowered while fingers 20 are spread to expand ring R to receive a stopper S (position (b)). The stopper may drop from the bottom of a stack through a hole in the upper portion of table 19 or, as shown, may be released from a chute 50 by pawls 52 operated by a lever 55 engaging a cam 58 which rotates with table 19. The assembly now passes to position (c) when upward movement of sleeve 26 operated by cam 30 causes horns 29, carried by sleeve 26, to contact ring R and force it off fingers 20 home onto the stopper while the latter is pressed against a spring-loaded abutment 40. The assembly then passes to position (d) where upward movement of pillar 25 ejects the stopper complete with ring, the stopper falling inside table 19 into a collecting box or delivery chute.

[Class 106 (iii)] The ground speed and the drift of an aeroplane are determined by the use of a divergent lens system 1, 2 for producing a virtual image a-b of an object on the earth and by adjusting the speed of the super-imposed image 6 of a source of light 5 seen by the observer 3 through a transparent glass 4, so that the two images continue to coincide. The image 6 may be formed by a source of light 18 and a perforated ribbon 7 traversed by an electric motor or by clockwork at an adjustable speed which is indicated by a speedometer driven by a drum 9. The speedometer reading multiplied by the altitude gives the ground speed. In a modification a mirror is included in order to reduce the distance between the source 5 and the glass 4. The apparatus may be rotated about a vertical axis, so that the travelling ribbon may be aligned first with the direction of flight and then with the direction of flying unaffected by the drift, thus giving data for determining the drift. The Specification, as open to inspection under Sect. 91 comprises also a modification, Fig. 4 (Cancelled) in which the illuminated object 15 is placed at the focus of a convex lens system 16, the observer viewing the image and the earth through the transparent glass 17.
