Title: Improvements in or connected with liquid measuring devices
IPC: B67D7/16
Filed: 1926-03-12
Abstract: 272,296. Shell-Mex, Ltd., and Arbuthnot, W. B. Carnegie-. March 12, 1926. Liquid meters. - A liquid-measuring device, particularly adapted for kerb-side petrol pumps, comprises two calibrated measures and a valvechanging device separate from them and actuated by an increase in the pressure of the, liquid. Fig. 1 shows. in plan, a valve apparatus consisting of two piston valves 8, enclosed in a casing 2, and mounted in a partition 7 which divides that part of the casing enclosed by the cover 4 from that enclosed by the cover 3. The valves are connected by a quick-throw-over device 17 &c., and the casing 2 is surmounted by two measuring-chambers (not shown). Liquid is sumpplied by a port 6 to the casing 2, and passes through the ports 9, 10 of the left-hand valve 8 to a recess 11 and the corresponding measuring- chamber. When this fills, the pressure in the casing 2 and on the piston 26 increases, and the piston moves down the cylinder 27, compressing the spring 28, and, by means of a connecting- rod 24, a slotted T-piece 20, lever 17, and rods 15, re-adjusting the valves 8, so that the measuring-chamber above the left-hand valve 8 is discharged through the ports 9, 10, chamber 7', and outlet 13. Spring-devices 31, 33 ensure a quickthrow-over of the valves, and the opening of the right-hand measuring-chamber causes a fall of pressure in the liquid, so that the piston 26 is pushed up the cylinder 27, and the upper end of the connecting-rod 24 rises to the other, then the upper, end of the slot 21. The valves havepacking 36 at one or both ends.

Title: Improvements in and relating to Feed Mechanism for Sewing Machines.
IPC: D05B27/10
Filed: 1917-05-14
Abstract: 114,360. Kiewicz, J., and Reece Button Hole Machine Co. May 14, 1917. Button-hole sewing-machines; feed by clamps. -Relates to sewing-machines of the type in which the feed movements of the work-clamp are derived from a rotating cam, and consists in positively connecting the feed-cam to the driving shaft by means of gearing, and in providing means actuated by the driving shaft for modifying the action of the gearing so that the feed-arm will have varying speed in timed relation with the operation of the stitch-forming mechanism. As applied to a button-hole sewing machine, the feed-cam 8, Fig. 1, is formed on its periphery with wormteeth that gear with a worm 11, Fig. 4, slidably keyed to a shaft 12 which is driven from the main shaft 5 by the shaft 17 and worm-gears 19, 20 and bevel-gears 15, 16. The worm 11 is slotted at 13 to embrace roller projections 14 on the shaft 12, and has a grooved extension 21 which is entered by rollers 22 carried by the forked end 23 of a bell-crank lever of which the other end 24 is connected to a link 26 having a strap 27 embracing an eccentric 28 on the main-shaft 5. By these connexions the worm 11 is reciprocated to accelerate the movement of the feed-cam when the needle is out of the work and retard or hold stationary the feed-cam when the needle is in the work. The shaft 12 has a pawl-and-ratchet connexion with the gear-wheel 15 so that it can be rotated by the usual means to move the workclamp to and from the button-hole cutting position when the main shaft 5 is stationary. To permit the gear wheels 15, 16 to be readily changed, they are held in mesh by rollers carried by a rod and bearing on the backs of the wheels.

Title: Improvements in or relating to apparatus for moulding and wrapping articles formed from toffee or like plastic material
Inventor: ROSE ALFRED GERMAN
IPC: A23G3/02
Filed: 1950-03-21
Abstract: 689,047. Moulding and wrapping toffee &c. ROSE BROS. (GAINSBOROUGH), Ltd. March 20, 1951 [March 21, 1950], No. 6935/50. Class 87 (ii). [Also in Group XXX] Relates to apparatus of the type in which a moulding device forms a continuous series of articles of toffee or like plastic material which leave the device as a string of articles connected by small portions of material and comprises a conveyer 21 having a series of pockets 22 of a shape appropriate to the articles, the conveyer being adapted to receive the string directly from the moulding device with successive articles passing into successive pockets and to carry the articles towards a wrapping machine, and means for transferring the articles in succession from the conveyer to the wrapping elements of the wrapping machine. The moulding device 12 forms the articles from the rope of plastic material 11 by passing it through the nip between two rollers 13, 14 each with cavities 16 which shape the articles e.g. toffees. The toffees, still connected by small portions of material, pass in a string down a guide channel 19 and enter successively the pockets 22. The conveyer, which may be long enough to allow the toffees to cool, carries them in front of a pusher 24 which reciprocates across the conveyer in time with the movement of the pockets. The pusher carries a knife 31 which cuts the material joining the toffees, which are thus pushed one by one into a pocket 28 of an intermittently rotating pocket wheel 29, the movement of the following string of toffee being restrained by a side guide 20. As the toffee is pushed into the pocket 28 it carries with it a wrapper 26 cut from a web 27 of wrapping material. Instead of the knife 31 an auxiliary pusher may be used. Specification 360,032, [Group XVII], is referred to in connection with the return movement of the reciprocating pusher, and Specification 621,500, [Group XXX], in connection with controlling the movement of a portion of the conveyer near the wrapping machine.
