IPC: A47L11/30
Filed: 1929-05-06
Abstract: 331,631. Finnell W. S. Jan. 21, 1929, [Convention date]. Floors, cleaning.- A floormopping machine comprises a frame 10 carrying a chamber 47 adapted to collect, by means of suction, dirt, &c., from the floor, and to discharge the dirt into a receptacle 59. The chamber 47 is located in a receptacle 36 which contains clean water and communicates with the floor surface through a conduit provided with a manually-operated valve and with a discharge pipe 38 carried by a squeegee 28 at the front of the machine. The pipe 38 is open at both ends to discharge water within the path of the squeegee. The chamber 47 is provided with a conduit leading to an electrically-driven fan 49 and with a channel 54 leading to a nozzle 57 in contact with the floor. The nozzle is formed with a semi-circular opening 58 so that air mixed with liquid flows up the channel 54 when the fan 49 is in operation. To prevent the liquid from reaching the fan a separator is provided in the chamber 47, consisting of a partition 69 provided with an involutely-wound strip leading from the wall of the chamber to the centre where it communicates with an opening 70 in the partition. If any moisture should succeed in reaching the fan it is expelled through a funnel 73. The separator causes the liquid to fall to the bottom of the receptacle 47 where it remains until sufficient has accumulated to open a flap valve 52 against the influence of suction created by the fan. The liquid then falls into the receptacle 59. This receptacle is provided with an opening 63 provided with a pivoted lever 64 which, when opened, forms with a rib 66 a spout to facilitate emptying the liquid.

Abstract: 568,031. Hydraulic transmission of power. AKTIEBOLAGET TELEPAR. Sept. 8, 1943, No. 14756. Convention date, Sept. 23, 1942. [Class 69 (ii)] A regulating valve or valves 35, 40 in the exhaust line from a hydraulic motor 25 controlled by a valve 3, creates a back pressure which acts on a spring-loaded piston 28 controlling a pump byepass valve 29, whereby a variable quantity of pressure liquid is returned to the tank 17. The throttle valves 35, 40 are in parallel and manually adjustable. The distributing valve 3 is operated by the machine to assume five positions of adjustment in which it is held by a spring-loaded pin 6. In the first position, in which the valve is set by a hand lever 9, both throttles are byepassed and valve 29 remains closed so that the motor is driven at maximum speed. In the next position, both throttles are effective and the speed falls ; a further reduction being effected in the next position when only one throttle 35 is effective. Further movement of the control valve cuts off the exhaust and the byepass valve opens to its full extent, thereby bringing the motor to rest. In the final position of the control valve, both throttles are byepassed and the motor reversed.
