Abstract: 648,898. Refuse shoots. SEYMER, V. H. Sept. 29, 1947, No. 26278. [Class 78 (i)] [Also in Group I] A method (Figs. 1, 3 and 5) of flushing a refuse shoot 1 having one or more hoppers 2 each provided with a cover 3, a manually or pedal operable device 4 for opening each cover and a tank 13 having a syphonic discharge device 18 for flushing the shoot; the method consisting in transmitting movement from the opening device 4 to a feed control device 12 controlling the water supply line to the tank 'whereby the tank will commence to fill on opening the hopper; transmitting movement from the opening device 4 to a movable discharge pipe 26 provided on the shoot whereby said discharge pipe will be positioned to effect delivery of refuse into a receptacle 33; and, when the syphon operates, automatically cutting off the tank feed and operating the short delivery pipe to effect delivery into a gulley 29, the tank feed remaining cut off until the next occasion of operating the opening device. Fige. 1, 5.-The housewife depresses pedal 4 pivoted at 5 and through link 6, quadrant 7, and quadrant 8, swings open cover 3 for her to insert rubbish into hopper 2. Pedal 4 also engages pin 10 on bar 9 and pushes down the bar, a first result of which is to swing the shoot discharge pipe 26 over to the right so that the refuse which has fallen down into the shoot is discharged into bin 33. Figs. 3, 5.-A second result of pushing down bar 9 is to swing anticlockwise the rocker arm 12 (which governs the discharge of water from tank 13) and then subsequently to flush the shoot 1, the bar being pivoted to arm 11 of the rocker arm 12. The anticlockwise movement of rocker arm 12 effects three things: firstly, by means of integral arm 14 it rotates valve 15 to allow water from pipe 16 to flow into the tank; secondly, it moves integral arm 22 to the right so that its roller releases cam 23 and allows ball 25 which is integral with cam 23 to pivot about 100 and so descend under gravity and in so doing it may operate a second ballvalve (not shown) which allows the water from pipe 16 to flow into the tank; thirdly, it depresses the syphon piston 18 which is pivoted to arm 11. The water rises and causes ball 25 to rise, so depressing cam 23 till rocker arm 12 under the action of spring 21 is free to turn clockwise. This clockwise movement effects three things: firstly, it rotates valve 15 to the right to turn off the water supply; secondly, it raises bar 9, thus swinging discharge pipe 26 to the left over gulley 29; and thirdly, it raises piston 18, so discharging the water down the shoot and into the gulley. Any dirt is caught in wire basket 34. Pin 30 on bar 9 prevents the hopper cover 3 being removed until pedal 4 is operated. Refuse may be prevented from being inserted into the hopper during flushing by providing spring pawls on bar 9 which are held by an abutment until released by a time switch. Each hopper may be provided with a hinged shutter coupled to the hopper cover, the shutter being closed when the cover is open (and vice versa) to prevent the escape of odours. The shoot may be provided with windows, or with access apertures for entry for scouring.
