Title: Improvements in and relating to closure mechanism for the fire openings of furnaces
IPC: F23M7/00
Filed: 1935-10-28
Abstract: 453,313. Furnace doors. BANKI, T., 1, Aprod Ucca, Budapest. Oct. 28, 1935, No. 29726. [Class 51 (i)] In order to reduce the cooling of the firebars due to the opening of the fire-door, a furnace is provided with a protecting cover adapted to move into position in front of the opening when the door is opened and to be moved away from the opening by pedal operated means when, for instance, coal is to be thrown in. In one form, Fig. 1, the cover comprises a part 6<a> fixed to a lever 5 pivoted at 4 and a part 6<b> fixed to a lever 7 pivoted at 9 and engaging a pin 10 on the lever 5. When the fire-door 3 is closed a projection 12 engages the part 6<a> and so holds both parts of the cover in the open position, as shown. When the door is opened, a counterweight 11 causes both parts to move together to form a cover over the opening abutting against a ring surrounding the opening. By making the part 6b heavier than the part 6<a>, the counterweight may be dispensed with. The part 6<a> may be formed with a small door 16 and an observation opening 18. The cover is adapted to be moved away from the opening by means of a pedal 15 connected with the lever 5 by a rod 14. In a modified form, the parts 6<a> and 6b are slidably mounted on guide rods 32, Fig. 7, carried by a ring 2 surrounding the firing opening. In a further modification, Fig. 3, the furnace has double sliding fire-doors 3 and the cover is in two overlapping parts 6<a>, 6b mounted on levers 5, 7 respectively so as to open like a fan under the action of a spiral spring 21 which replaces the counterweight 11. When in position over the opening, the cover abuts against a ring 2 formed by fixed upper and lower members and side members carried by the adjacent edges of the sliding doors. The ring 2 may be formed with an adjustable secondary air inlet. The form of cover shown in Fig. 3 may also be applied to a single inwardly opening door.

Title: Improvements relating to spinning machines for artificial threads
IPC: D01D13/02
Filed: 1958-09-18
Abstract: <PICT:0875715/IV (a)/1> <PICT:0875715/IV (a)/2> <PICT:0875715/IV (a)/3> In a spinning machine for producing artificial threads, the thread winding or collecting device, including its driving and traversing elements, is in the form of a compact self-contained unit detachably mounted on the machine.  As shown in Fig. 1, which is a side view of a portion of a spinning machine, a bundle of filaments from a spinning head (not shown) is led over driven rolls 2 to one or more collecting or winding devices, each arranged as a compact selfcontained unit in and on a frame or housing 3.  Each winding device has a friction roller 4 constructed as an electric motor having an external rotor rotating about a stator which is fixedly mounted on the housing 3 with its axis arranged transversely of the machine.  A package support 5 axially parallel with the roller 4 bears directly, or through the package wound thereon, against the roller 4.  The support 5 is mounted to be movable transversely of its axis, as shown in Figs. 2 and 3, by fixing it on a guide member 6 which is displaceable by means of a ball-bearing guide along a rail 7 fixed in the housing 3.  As shown in Fig. 2, which is a plan view of a single winding unit, the support 5 is rotatable about a fixed spindle 20, one end of which is mounted in the guide member 6.  Yarn packages 9, 10 are built up on a tube (not shown) which can be withdrawn axially of the spindle 20.  The spindle 20 and the member 6 are prevented from rotating about the rail 7 by an arm 21 (Fig. 3) having at one end a wheel 22 which can travel in a channelshaped rail 8.  The latter can be moved transversely of its length in order to permit the spindle 20 with the package support 5 to be adjusted at an angle to the horizontal.  The guide member 6 is engaged by a spring or by a weight-loaded cable (not shown) in such a manner that the yarn packages in the support 5 are urged against the friction roller 4 so as to be rotated thereby.  A double thread guide 12 (Fig. 2) is reciprocated in a bearing in known manner in a path parallel with the package support 5 by a peg 14 engaging in the groove of a cam drum 13 which is a motor having an external rotor.  Each housing 3 is guided by rollers 15, 16 (Figs. 1 and 2) in a machine frame 19 and is provided at its back with electric contact pins 17, 18 which engage co-operating electric socket contacts in the machine frame 19 when the housing 3 is pushed into the operative position.  The broken lines 23 indicate the position of the yarn packages when fully wound, the supports 5 then having the position also shown in broken lines. The apparatus permits of increase in spinning capacity in a spinning machine of given length.

Abstract: 1441151 Pneumatic looms CROMPTON & KNOWLES CORP 26 June 1973 [24 July 1972] 30244/73 Heading D1E In a pneumatic loom, weft equivalent to a fraction of the pick length is blown into a dummy shuttle 30 by a nozzle 56 passing through a picking chamber 52 and projecting into the shuttle, the shuttle is then picked by blowing air into the chamber 52 and simultaneously blowing air through nozzle 56 to eject the weft passing therethrough after the shuttle 30. A cam-controlled clamp 184 closes when sufficient weft has been drawn from the supply 186. Weft is cut and clamped by devices (29) Fig. 1 (not shown) mounted at the ends of the sley, and the weft end projecting from nozzle 56 is drawn back by puller 180. Air is supplied to chamber 52 and nozzle 56 from a high pressure air source (90) Fig. 1 (not shown) via valves 122 and 124, which are controlled by slide valves 130, 132 operated by common sliding frame (163) Fig. 2 (not shown) which is reciprocated by a cam (168). Air is also supplied to nozzles 56 from a low pressure air source (148) via a valve 146, to blow the weft into shuttle 30. Valve 146 operates to close itself as soon as high pressure air is supplied to nozzle 56 to eject the weft after the shuttle. Dummy Shuttles, Figure 12. The shuttle 30, which is double acting comprises a cylindrical body 226 with an internal cavity 34 which narrows towards each end. In the centre of cavity 34 is a generally spherical member 36 with oblique slots 42 therein in order to create a vortex air flow when the weft is blown in, to form the weft into coils in the shuttle 30. Shuttles guiding; reeds, Figures 10 and 20. The shuttle 30 is guided in the shed by plates 206 having a circular aperture 212, and a slot 214 through which the weft passes as the sley withdraws from beat-up. The rear edge 218 of aperture 212 serves to beat the weft up. The plates 206 and their spacing is so dimensioned that the shuttle is supported by a cushion of air as it passes through. In an alternative embodiment, Figure 20, the slot 214' extends generally vertically and a vertical extension 238 of the plate 206' beats-up. Shuttles checking. The shuttle 30 is checked by pneumatically operated swells 64 in the bore 52 from which the shuttle is picked and into which it is received. The swells slide radially inwards when high pressure air is supplied to them, as the shuttle arrives from valve 94, which is controlled by a slide valve 116 attached to the sliding frame (163). The shuttle 30 is brought to a complete stop by a yieldable stop 60 which has a series of annular grooves 62 to increase its yieldability. Beat-up motions Figures 21 and 22. In one embodiment, Figure 21, the sley is driven by a pair of conjugate cams 254, 254 acting on follower rollers 250, 252 on arms 246, 248 attached to the sley. Alternatively, Figure 22, where the guide plates 206' are as in Figure 20, the sley swords are short, and are oscillated via pivoted levers 268, 267 and 262 driven by conjugate cams 254' and 256'.
