Title: Improvements in gas lighters
IPC: F16J15/34
Filed: 1965-11-16
Abstract: 1,055,690. Gas lighters. S. H. NEWMAN. Nov. 16, 1965 [Nov. 19, 1964]. No. 48582/65. Heading F4F. A dismantable gas lighter comprises a casing 1, interchangeable reservoir 2, gas valve 3, burner 4, snuffer cap 5 and a press-down thumb-piece 6. When the thumb-piece is depressed it causes a lever 15 to pivot at 48, the thumbpiece 6 and lever being joined by lugs 15a in holes 39, Fig. 6A (not shown), and lowers the axle 54 of a pawl 14 which rotates a ratchet-wheel 13, thus causing the flint wheel 7 to turn against a flint 8. Depression of the thumb-piece 6 also causes gas to escape from the valve 3 by raising the burner 4 by means of a lever 10 which pivots about a lug 18a projecting from a vertical partition 18 of a platform 17, Fig. 12-15 (not shown), which has a U-shaped cross-section and on which the lighter mechanism is carried. When the thumb-piece is released a spring 57, anchored on an axle 58 and in a cut-out 57 of a support 60, Fig. 6B (not shown), returns it to its original position. A spring 57 anchored to the lever and bearing against the pawl 14, Fig. 7A (not shown), holds the latter in engagement with the ratchet-wheel 13, but due to its shape does not rotate it. A knurled wheel 11 which extends through the cap 5, Fig. 9 (not shown), when rotated regulates the height of the flame by turning a wheel 73 via a worm 68, wheel 70, shaft 69 and pinion 71 all supported by the support 60. The end 79b of a spring 79 applies a catch 16, Fig. 5, and also Figs. 29-32 (not shown) against the casing 1 and into engagement with a lug 5f of the cap 5 and also urges the platform 17 on which it is pivoted into engagement with a lug 5g of the cap. The cap is connected to the casing 1 by the frictional face 16b of the catch. The end 79a of the spring 79 bears against a bobbin 78 retained within a flint pushing means 77 which slides in a flint tube 9. The flint tube is of square cross-section, open at one side and has vertical flanges which attach it to the platform. If the operating mechanism is removed from the lighter casing against the friction of the catch, the catch may then be released from a hook 88, Figs. 33-35 (not shown), and rotated clockwise to the position shown in solid lines, Fig. 36 (not shown), whereby a slot in the platform is revealed and the flint replaced through the open side of the flint tube.

Title: Adjustable wheel mounting
IPC: A01D34/74
Filed: 1965-11-17
Abstract: An adjustable wheel-mounting for a rotary-scythe lawn-mower comprises a wheel-support 23, which may be part of the mower-chassis or a part attached thereto, and which has a series of holes 16, each able to receive the wheel-axle 10, and being interconnected by a slot, the axle having an end-portion which passes through one of the holes and carries a nut 18 threaded on to the end-portion and also having a main portion extending on the side of the support away from the nut to carry a wheel-bearing 12, the outer end of the axle beyond the wheel-bearing having a hand-wheel 14 whereby the axle may be rotated to tighten or loosen the nut, the nut being retained within a cap-disc 20 which permits it only to be loosened sufficiently to enable the axle to be moved up and down in the slot to an alternative position.  The nut has an oblong extension 19 which is located within one of the holes in the support, each hole having a ledge 17 against which the extension abuts, the arrangement being that the nut can be rotated about a 1/4 of a turn by the handwheel, whereas it is locked against the cap-disc but the oblong extension then lies parallel to the slot, enabling the axle to be moved up or down to an alternative position.  Contra-rotation of the hand-wheel will then cause the extension to abut the ledge 17 in the next hole.
