Class 75(iii) A pyrophoric lighter provided with means for rotating the flint holder each time the lighter is used in order to provide for even wear on the operative face of the flint, comprises flint supporting means adapted to carry a flint non-rotatably therein and including resilient means for urging the flint towards a friction member movably mounted on the lighter casing, and means movable into and out of the path of movement of a cover on the casing for automatically rotating the flint supporting means about its axis upon movement of said cover between its closed and open positions. An alternative form of pyrophoric lighter described and claimed comprises a frame supported and secured to the top plate of the lighter body and embodying a bottom member and a pair of spaced parallel side members rotatably supporting a friction wheel between them, a flint urged by resilient means into con-' tact with the friction wheel and slidably positioned in a sleeve supported on a protruding portion of the bottom plate of the lighter body and projecting through registering openings in the said top plate and frame bottom member, and gear means operatively connecting the friction wheel to said sleeve for rotating the sleeve and the flint as the friction wheel is rotated. The flint holder shown in Fig. 2 comprises a cylindrical tube 16 rotatably mounted in a bore 13 in a lighter body 12 and having reduced ends 18 received, respectively, in a circular recess in a screwed plug 20 which closes one end of the bore 13, and in an aperture in the body 12 adjacent the flint wheel 19. The flint 15 is of rectangular cross section and has one end engaged non-rotatably in a correspondingly shaped bore in one of the parts 18, whilst the other end is engaged by a coiled spring 21 compressed by a screw 22 engaged therewith and having a spherical head 22<1> supported in a second recess in the screw plug 20. On closing the cover 11, Fig. 3, of the lighter the lower edge engages a pin 25 slidable in a bore 14 to force the latter inwards against the action of a spring 27, so that the inner end of the pin 25 engages gear teeth 17 on the tube 16 to 'turn the latter together with the flint 15 each time the lid is closed. An embodiment of the alternative 'form of lighter is described in which the friction wheel is rotated by the user's thumb and has formed integrally therewith or secured thereto a pinion which drives a second pinion in mesh with teeth provided around the outer end of the flint tube so that the latter is rotated each time the friction wheel is actuated. For preventing rotation of the flint in the flint tube when the latter has a different cross section than that of the flint, gripping means may be provided. Specification 626,585 is referred to.

Filed: 1938-09-17
Abstract: 519,203. Valves. BLEASE, J. H., and FOWLER, G. Sept. 17, 1938, No. 27148. [Class 135] [Also in Group VI] An anaesthetic apparatus in which a rotatable valve member progressively closes the passage of air direct to the patient's mask whilst allowing an increased proportion of a gas such as oxygen to vaporize an anaesthetic liquid, is provided with a by-pass whereby, in a final position of the valve, the gas is exclusively led below the surface of the liquid to pass therethrough and then to the mask. The apparatus comprises a casing 1 supporting a bottle 3 for liquid anaesthetic provided with an air &c. admission tube 7. The casing has a web 5 having a perforation 6, Figs. 2 and 5, leading to the tube 7, and perforations 9, 10 which may be closed to the desired degree by a disc valve element 14 having tapered ports and connected by a wing or butterfly valve element 12 to a control knob 11. A connection 16 leads to the mask, a connection 17 is provided for air and a pipe 18, having branches 19, 20, is connected to a supply of oxygen, nitrous oxide &c. The branch 20 communicates with a groove 21, Fig. 3, in the valve body opening into a passage 22 leading to the space between the head of the valve 11 and the disc 14. The branch 19 is placed so that in one position it comes opposite to a port 23 opening into a radial passage, as shown at 24 in the modified construction of Fig. 5, which communicates with a pipe 25 the outlet of which is opposite to the opening 6 when the port 23 is opposite the passage 19. As the knob 11 is turned in a clockwise direction from the position in which air is being drawn by the patient directly from the inlet 17 the ports 9, 10 are gradually opened to cause a portion of the air aspirated through port 10 to pass down into the bottle across the top of the anaesthetic liquid, and then as groove 21 comes opposite pipe 20, oxygen &c. passes from the tube 18 direct to the outlet 16, but some will also pass through the disc valve 14 down the tube 7 and through the anaesthetic. Further movement of the knob 11 will cut off the direct air supply and in the final position the whole of the oxygen will be directed through the port 23, pipe 25 and tube 7 to pass through the anaesthetic. In the modification shown in Fig. 5, the tube 7 is surrounded by a coaxial tube 30 having fins 27.

Abstract: 452,686. Milling - machines. LIDKOPINGS MEKANISKA VERKSTADS AKTIEBOLAG, Lidk÷ping, Sweden. Oct. 2, 1935, No. 27233. Convention date, Nov. 2, 1934. [Class 83 (iii)] [See also Group XXIII] A machine of the kind in which a milling or grinding tool moves orbitally around the stationary work during operation has work-supporting means moving with the tool and arranged so that part only of said supporting means is mounted for adjustment during operation to take up play caused by reduction in the size of the work. The bed 1 is fitted with rollers 2 which support a drum 3 carrying the tool with its associated supports for the stationary work 4 which may be an axle for aeroplane landing gear. The drum is driven from a motor 5 through gearing 6 and worm gearing 8. The worksupports consist of opposed members 15, 16, the latter resiliently mounted, and a roller member 17, these members being mounted in holders 10 adjusted radially simultaneously by means of eccentrics 11 interconnected by shafts 14. The tool, shown as a grinding wheel 18, is directly driven by a motor 21 and is mounted in a frame 20 pivoted at 19 to the drum. The axis of the grinding wheel is offset from a plane passing through the axes of the work and the roller 17. The grinding-wheel is radially adjusted by means of differential gearing operated from a hand wheel 23. A ring gear 24 on the drum drives through gears 25, 27, 28 an internal gear 29 connected through gears 30, 31 and 33 to a second ring gear 34 which is thus normally rotated at the same speed as the drum. When the hand wheel is rotated a lever 37 carrying the gear 30 transmits additional relative rotation to the ring 34 and this movement is transmitted through gearing 38 ... 40 to a screw 41 operating the grinding wheel frame. In a modification, Fig. 6, wire stock may be drawn past the grinding-wheel by means of a reeling device 42 and the supporting- roller 17 may be obliquely arranged to facilitate the feed of the wire. Specification 418,742, [Group XXIII], is referred to.
