Title: Improvements in regulating valves for gas
IPC: F23D14/48
Filed: 1927-11-03
Abstract: 305,519. Yates, H. J., and Howlett & Co., Ltd., M. Nov. 3, 1927. Piston valves; closure members.-A gas regulating valve arrangement for atmospheric burners comprises a grooved plunger 7 sliding within a sleeve 6 in combination with a tubular rotary member 11 having a slotted or perforated disc valve face controlling gas discharge orifices 5. The combined valve is actuated by a rotary spindle 10 the screwed portion of which reciprocates the plunger 7 so as to vary the effective area of the taper grooves 8, and at the same time rotates the disc valve by means of the crosspin 12. A guide pin 10<a> prevents rotation of the plunger 7. The lower edge of the sleeve 6 is rounded off, as shown at 22, to facilitate the passage of gas. Fig. 4 shows a modified arrangement in which the plunger 23 is integral with the actuating screwed spindle 25 and the rotary valve is interconnected therewith by a square sliding spindle 27.

Title: Knitting machines
IPC: D04B11/18
Filed: 1963-07-25
Abstract: 973,268. Knitting-machines. WILDMAN JACQUARD CO. July 25,1963 [July 30, 1962], No. 29488/63. Heading D1C. A straight bar knitting machine has a vertical bed in which alternate needles 22 are fixed to the main needle bar 21 and intermediate needles 24 are fixed in an auxiliary bar 23 and 13 characterized in that rack gears 25 fixed to the auxiliary bar are movable by oscillatable gears 31. The shaft 28 has a cam 33 keyed to it by means of a pin 34, as the shaft turns the cam operating by means of a plunger 49 causes the locking or unlocking of needle clamps 40. 'The cam 23 also contains a detent 35 which on rotation of the cam is spring operated to engage in a hole in one of the oscillatable gears 31 and hence on further rotation of the cam causes the auxiliary bed to rise or fall with respect to the main bed by means of the rack gears 25. As shown in Fig. 6 a plate 64 with extensions 66, 67 is connected to a gear 58 meshing with a gear 57 which is fixed to shaft 28. As the needle bed descends (Fig. 7) extension 67 hits the screw 74 causing partial rotation of the cam 33 which engages the detent 35. On the next descent the slide 71 is moved so that extension 67 engages a higher stop 73 and more rotation of the shaft 28 is caused and thus the auxiliary needle bed is raised. To lower the needle bed the same procedure takes place with extension 66 and screws 72 and 73. The slide 71 is operated from a system of levers controlled by a series of cams on the main machine shaft Fig. 1 (not shown). Each needle clamp may be opened separately by means of a clamping latch 53 Fig. 3 (now shown) and a hard rubber pad 46 is provided in the jaws of the clamps to provide a firm grip. Specification 867,391 is referred to.
