Title: A double twist frame
IPC: D01H1/10
Filed: 1964-07-02
Abstract: A two-for-one twisting frame has, remote from the twisting-position at least one pneumatic device for threading-up a winding-off package, so that delay caused when the winding-off-package has to be threaded up at the twisting-position is avoided.  The package-carriers are of the type described in Specification 992,909 having a cone-shaped member for insertion in a tapering socket of the revolving member of the twisting-spindle. The revolving guide plate of the spindle has a slot for the egress of yarn communicating with one in the socket and arranged to lie in a particular direction when the spindle comes to a halt, while the balloon limiter may be arranged to swing open to facilitate drifting.  A frame has a number of threading-up devices each comprising a recepticle 24 (Fig. 2, not shown) communicating at 25 with a suction-pipe 26.  A spring-urged sleeve 27 slides in the recepticle and comprises a tapering socket 29 a seal 30 with a duct 31, a thread-chamber 32 closed by a screen 33 and ducts 34 leading to a groove 35.  The socket receives a conical member 9 of the package carrier and when the sleeve is depressed, the inside of a tube 15 is placed into communication with the suction-pipe 26, so that thread placed in the inlet of tube 15 is drawn down to collect in chamber 32.  The carrier is so threaded-up is transferred to one of a number of waiting positions 38, Fig. 1, (not shown), in readiness to be moved to a twisting position when one becomes vacant, the thread-end being meanwhile gripped in a clip 39.  At the twisting-position, the spindle is driven by a wharve 4 held in contact with a driving-belt by an idler 3.  When the yarn here is exhausted or broken, the carrier is lifted out of its socket, and transferred to one of the waiting positions 38 to await its turn to be transferred to a threading-up position.  It is replaced by a threaded-up carrier from the waiting position, the yarn being put into a slot 13 and lead over a guide 22 to be joined to the end depending from the take-up means.

Title: Fuel injection and mixture controlling apparatus for internal combustion engines
IPC: F02M41/08
Filed: 1933-10-09
Abstract: 424,019. Regulating; fuel pumps. HIGH, C. F., 705, East Street, Flint, Michigan, U.S.A. Oct. 9, 1933, No. 27746. [Class 7 (vi)] [See also Groups XXVIII and XXXIV] In engines working with liquidfuel injection and spark ignition, the fuel-pumping unit comprises a number of pump elements supplied from a common chamber to which the fuel is fed past an adjustable metering-valve, which is connected to the air throttle for simultaneous adjustment therewith. Fig. 1 shows a pumping-unit comprising several pump plungers 6 arranged around and actuated by a cam 11 so as to draw fuel from a common chamber 46 through ports 23, 22, and discharge the same past valves 29 into pipe lines leading to the fuel-injection means arranged on the several cylinders or in the induction pipes leading thereto. Fuel supplied to the units at 35 passes through a filter 37 into a recess 40 in the metering-valve 38, which has a crescentshaped outlet 41 opening more or less to the chamber 46 according to its axial adjustment. This adjustment is effected by a cam lever 60, Figs. 1 and 4, having a face cam 63 engaging a pin 56 bearing on the valve 38. The lever 60 also has a cam surface 75 which engages a roller 74 on a lever 67 having a flexible connection. 76 to an arm 78 on the air throttle 79. The fulcrum 66 of the lever 67 may be adjusted by a thumb-nut 71 so as to vary the relation between fuel and air. Fig. 5 shows a simpler form in which a manually-controlled disc 83 has a cam 84 engaging the pin 561 of the fuel metering valve, and a connection 86, 85 to the air throttle 88. In modifications, dash-pots are connected to either of the throttle controls in Fig. 4 or 5 for giving a lag in the opening of the throttle, and therefore a richer mixture, during sudden accelerations. In a modified form of pumping-unit, the fuelmetering valve is tapered towards its upper end, instead of being provided with the port 41. Lubricating.-The pump plungers 6 are provided with spaced angular grooves 21, which lift oil in stages up the pump cylinders 5 and keep the same lubricated. Oil for this purpose is admitted at 52 and passes through a filter 50, 51 and passages 51<2>, 53, 54 to oil spaces 2 surrounding the pump cylinder 5 and communicating with the plungers through openings 19. Lubrication is thus also supplied to the metering-valve 38, and through ports 51<3> and 55 to the cam mechanism and its bearings.

Sluice gates.-A movable weir or sluice-gate with a hinged top flap or head is provided with a single lifting means for operating the gate and the flap arranged in the pier slot at each pier, the said means engaging directly with a bar attached to the flap and extending into the pier slot without passing through the side bracket of the flap. Preferably an extension of the lifting means is attached between the flap bar and a suspension pin on the gate in such a way as to come under tension when the flap is erect but to be free of load in intermediate positions. The gate 1, Figs. 1 and 2, carries at each side a sector-shaped bracket 2 which makes a tight lateral joint with the hinged head or flap 3. Attached to the latter is a bar 4 which projects into the pier slot 5 above the bracket 2 and is connected to a lifting chain 6. An extension 7 provides a rigid connection between the chain 6 and a pin 8 on the gate. The chain 6 passes over a sprocket 9. When the chain is hauled up, the flap 3 is first lifted, during which movement the extension 7 turns freely upwards, the flap bar 4 sliding in a slot therein. The bar 4 describes an arc 12 about the axis of rotation of the flap, and the upper end of the slot in the extension 7 describes an are 13 about the pin 8. The upper point of intersection of these arcs is the position at which the tractive effort is transmitted to the pin 8 and to the gate 1, Fig. 5 shows a construction in which the sluice is intended to be lifted with the flap let down. The part 6a of the lifting chain is attached to the flap bar 4. In the arrangement shown in Fig. 6, one part of the chain 6 is attached directly to the flap 3, while the other end acts on the gate 1 through the medium of an idle pulley r' mounted on the free end of the extension 7. A compound pulley block may be used instead of the pulley r'. The track 14. Fig. 2, of the gate may be inclined to prevent the bar 4 from striking it.
