Abstract: 353,888. Valves and cocks. FAIRBROTHER, C., 3, The Foursome, Chertsey Lane, Staines, Middlesex. April 29, 1930, No. 26173/29. [Class 135.] Lift valves actuating - mechanism; leakage, preventing; spindles.-A valve or cock adapted for use on delivery road tanks for petrol &c. comprises a lift disc valve member 26 secured by a ball-andsocket joint 36, 40 to a spindle 44 for self-aligning adjustment, the spindle being packed against leakage by a flexible bellows 50, or a plain diaphragm, which is secured to spindle and casing and made fluidtight by washers, as shown. The valve is biased to closing position by an enclosed spring 60 and is opened by a detachable handle fork 76 having pivotal pins 78 engaging in recesses in the central boss 20 of the cover-plate 18 and lifting pins 82 engaging under a flange 84 on the valve spindle. When the operating handle is removed the spindle can be protected by a screwon cover 66 which, by an adjustable screw 70, can apply pressure to the spindle and the closure 28, 30 ; if the screw 70 is removed the cover can be screwed down upon a washer 68, and secured by a padlock by means of a perforated flange 166 and an apertured lug 118. The packing rings 28, 30 of the closure are wedge-shaped and are secured by being gripped in cylindrical portions near the bases of conical grooves. A modification is described in which the valve opens downwards with the forked handle acting cam-like on the upper end of the valve spindle, the valve being biased to closed position by a spring acting through a plate and ball under the valve disc member.

Filed: 1944-12-30
Abstract: 589,307. Latches. SPOONER, R. A. Dec. 30, 1944, No. 26184. [Class 44] In a latch of the type in which the head of the latch bolt may be withdrawn from the latch casing against spring pressure and turned through 180 degrees to reverse the hand of the latch, a key-slot is formed in the casing to position a key adjacent the tail end of the bolt head and clear of the runner plate on which the said bolt head is slidably and rotatably mounted, so that the bit of the key can press the tail with the head thereon outwardly from the casing. In Fig. 1, a runner plate 1 slidably mounted in a casing 2 is retracted by a rotatable follower 15 against a spring 14. A bolt head 4 is pressed against a projection 3 on the plate by a spring 7 mounted on the tail 5 of the bolt head between the projection and a head 6 on the end of the tail. A key 9, which passes through a cutaway portion of the plate, pivots in a hole 10 in the casing to press upon the head 6 and eject the bolt head from the casing. In Fig. 3, the tail 17 is slidably mounted in a sleeve 19, which is itself slidably mounted in a fixed projection 24 in the casing. A light spring 21 is mounted on the sleeve between the bolt head 4a and the said projection, and a stronger spring 23 is mounted on the tail between a head 18 on the end of the tail and a collar 20 on the end of the sleeve. A projection 25 on the runner plate 26 engages the sleeve between the collar and the fixed projection. The key-slot 27 is provided.

Abstract: 251,315. Fairweather, H. G. C., (National Acme Co.). Nov. 3, 1924. Turrets. - Indexing- mechanism for turrets comprises a cylinder 4 gearing with a driven member 9 which is provided with elements adapted to be engaged by cams secured to an indexing-member 13 the arrangement being such that during a complete indexing movement of the member 9 some of the cam faces on the cams engage with some of the elements to cause the rotation of the member 9, while other cam faces engage some of the elements to control the momentum of the member 9 and prevent overrunning. As shown, the cams comprise a diamond-shaped cam 17 and two cams 18, 19 bolted to the member 13, faces on these cams farming a channel through which one of the elements on the member 9 is guided. The elements in the form of rollers 1, 2, 3, are spaced at equal distances apart. The rotation of the member 9 is effected by the engagement, in succession, of a cam-face 20 with the roller 1, the face 23 with the roller 2, and the face 27 with the roller 1. The momentum of the member 9 is controlled by successive engagement of the face 21 with the roller 1, the face 24 with the roller 3 and the face 28 with the roller 1. At the end of a complete indexing movement the roller 1 is in the position formerly occupied by the roller 2.

Filed: 1945-10-11
Abstract: 636,245. Wind musical instruments. SOMERVILLE, J., (trading as RENO ELECTRICAL & ENGINEERING CO.). Oct. 11, 1945, No. 26570. [Class 88 (ii)] The body of a saxophone or similar instrument is built up in sections joined by longitudinal seams and the tone holes, which may be in a separate flat strip, co-operate with valves which produce an interior surface free from cavities. In a preferred embodiment the body and bell are formed of two pressings 1, 2, Fig. 4, which are joined along their outer edges while their inner edges are bridged by flat strips 9, Fig. 5, in which the tone holes are formed. A slotted cover 10, Fig. 3, encloses these strips and the valves and the action may be secured to the strips 9, the cover 10 or the body. In an alternative form the central stripsare not used, the two halves being joined together along front and rear longitudinal seams. In this case the tone holes are set in a line along the front seam, half of each hole being formed in each section during pressing. If desired, the part of the body in which the tone holes are formed may be of reduced section, and the cover made of shape and size approximately to the dimensions of known instruments, Fig. 19 (not shown). In either case the valves are arranged to avoid internal pockets adjacent to the tone holes by having extensions on the valve heads which enter and fill the cavities when the valves are closed, Fig. 14 (not shown), by having a form of countersunk valve, Fig. 15 (not shown), or by using valves which open inwards, Fig. 11 (not shown). The instrument may incorporate the resilient valve seating gasket described in Specification 636,244, the tuning slide described in Specification 636,243, and self-locating springs described in Specification 633,476.

Thermoplastic parisons for bottle blowing core delivered by pairs of tongs between an extrusion station and a laterally displaced mould charging station past which a plurality of split moulds is traversed. A plurality of pairs of tongs having fixed elements 7 and movable elements 6 is indexed stepwise past continuously extruding nozzle 4 with the element 6, carried from boss 9 upon sleeve 8, opening and closing to grip upon and sever tube 5, immediately below projecting nozzle core 28, by the action of stationary cam 20 upon the arcuate movement of roller 26 attached to boss 9. After severing, the closed tongs are lowered at the extrusion spaced by vertically reciprocable rod 14 carrying channel 12 which engages with roller 18 attached to sleeve 8. During movement to the mould charging station the tongs are raised by stationary guide channel 16 whereupon they are lowered by further vertically reciprocable means to deposit parison 5a upon blowpipe 23 within the closing sections of mould 2, the tongs disengaging by roller 26 riding over abutment 27. The tongs are raised during subsequent indexing by stationary guide channel 17 and the inflated parison eventually ejected by air blast upon moving belt 24. Alternatively, a single pair of tongs may reciprocate between the nozzle 4 and the charging station or, with two pairs of tongs each may supply a different station.
