In a cleaning device for textile machinery, especially spinning frames, a combined blowing and suction car is mounted upon and for movement along a rail track extending above the machinery and has at least one suction nozzle through which air is drawn by appropriate fan means, a blowing device being provided which is adapted to direct air at the machinery. The suction nozzle extends downwardly to the immediate vicinity of the ground and the blowing device comprises a blower nozzle arranged opposite the suction nozzle. The car is preferably provided with two suction nozzles, Fig. 1, which may be completely or partly flexible and have orifices 3 at their free ends. The fan means comprises fans 2 which are connected to a filter box 4 provided with a pivoted filter grid 5, Fig. 3 (not shown), the grid being movable by an electromagnet, for example, when the car reaches a certain position on the rail 19 so that fibre material accumulated on the grid may be blown into a hopper 7 leading to a storage container (not shown), e.g. a filter chamber provided with a replaceable filter cage insert. The blowing device comprises blowing ducts such as 13 and 13<SP>1</SP> which may have auxiliary blowing orifices such as 14 at different levels, the parts of the suction nozzles disposed opposite the blowing orifices having suction orifices such as 11 so that a transverse circulation 12 is obtained. When the car reaches the position on the rail where the hopper 7 is located, control means automatically stop the car and open the filter box 4 to allow the fibre material to be blown off the grid, the control means automatically starting the car again and closing the box 4 after a certain length of time has elapsed. The control means preferably comprises an inclined rail 25, Fig. 5 which is engaged by a roller 26 of a lever 27 provided on the car and operating appropriate switch gear. Alternatively, when the car is stopped the filter grid magnet may receive current from live rails 28 by means of sliding contacts 29. A limit switch 30 is provided which is operated by the car. A time relay 34 which is coupled to a solenoid 33 is energized so that after a given length of time the latter moves the rail 25 to disengage it from the roller 26. The rail 19 is preferably endless but may be otherwise. In the latter case a hopper 7 may be provided at one or each end of the rail; the filter grid may be moved mechanically when the car reaches the end of the rail and the car may be automatically stopped there for a short time before reversing.

Abstract: 842,031. Endless conveyers. U.D.ENGINEERING CO. Ltd. Dec. 29, 1958 [Oct. 3, 1957], No. 30966/57. Class 78 (1). [Also in Group XXXVI] A device for giving an indication when a number of unclosed containers pass in succession a given point comprises means which passes a signal to a storage device each time a container passes the point, a closure detecting device which clears the storage device each time a closed container passes the point and means which operates a signal device or stops the feed of containers when a predetermined number of signals has been stored in the storage device. The Figure shows apparatus for detecting the passage of a succession of unclosed milk bottles. The presence of a bottle 1 at the detection point operates a feeler 6 which causes a switch 8 to change over and so discharge a previously charged capacitor 10 into a further capacitor 13 so that each uncapped bottle causes the capacitor 13 to be charged incrementally until the voltage across it is sufficient to fire a gasfilled valve 15 and operate a relay B. This relay operates an alarm or causes the feed of bottles to cease. If the bottles have a cap on them a sensing device 3 operates a relay A causing a contact A1 to short-circuit the capacitor 13 so that the relay is not operated by capped bottles. The circuit may be restored to normal after operation of the relay B by operating a push button 17 to discharge capacitor 13 and open the anode circuits of the tube 15 so that the tube extinguishes. The sensing device 3 is preferably of the electromagnetic type described in Specification 800,782.

Title: Bobbin handling system for yarn winders
IPC: B65H54/26
Filed: 1972-07-05
Abstract: 1399747 Supplying bobbins to patrolling tenders LEESONA CORP 25 Sept 1973 [5 July 1972] 31479/72 Headings D1F and D1J An apparatus for servicing a plurality of winding stations 48, Fig 3, each of which is operable to unwind strandular material from a bobbin 12 comprises tender means 46 operable to patrol said winding stations and service each said station to reinstate strand processing thereat, filled bobbin conveyor means 36, Figs 3 and 8, disposed proximate to said tender means 46, means 92 on said tender means for removing a bobbin 12 from the conveyor means 36, and means 98 on said tender means 46 to conduct the removed bobbin to a locus proximate one of said stations 48 where the bobbin is positioned preparatory to unwinding of the strandular material therefrom. The system can handle varius types of bobbins 12, each type being initially fed to its own holder 24, Fig 8. Distributing buckets 38 carried by conveyor 36 move past and below the holders 24 and are designated for receiving only one type of bobbin. When a bucket 38 is empty it causes a gate 60 of_the bobbin holder 24 containing the proper type of bobbin to open and so deposit a filled bobbin in the bucket 38. The patrolling tender 46 is positioned below the buckets 38 and preferably moves in a direction opposite to that of the conveyor 36. When a delivery tube 98 on a patrolling tender 46 requires a bobbin it causes a gate 84 of a bucket 38 containing an appropriate type of bobbin 12 to open and so deposit the bobbin in the tube 98.  As the tender 46 moves around the winder and comes upon a winding station 48, Fig 3, requiring a fresh supply bobbin, as determined for example by a phototransducer 132, the appropriate delivery tube 98 drops a bobbin into the magazine 52 of that station and positions the unwinding end 28 for retrieval by the knotter on the tender 46. The bobbin 12 initially drops down to a reserve position 50, Fig 3, and waits there while a bobbin 12 at an unwinding position is held on a peg 166 mounted on a rotatable carrier 170. When the bobbin 12 on the peg 166 is empty, or the yarn breaks, the carrier 170 is rotated anti-clockwise and this causes the rejected bobbin 12 to be displaced to the left and the peg 166 to rotate to a setting where it enters the reserve bobbin to move the reserve bobbin to the unwinding position. Empty bobbins. When a bobbin is empty it is passed to one of a plurality of empty bobbin conveyors 54, one for each type of bobbin. Each of these conveyors 54 discharges its bobbins into separate sorters from which the bobbins are either ejected from the system or are returned to the associated bobbin holder 24.
