Patent GB-399174-A (GB)
Title: Improvements relating to carpet scrubbing machines
IPC: A47L11/283
Filed: 1932-03-22
Abstract: 399,174. Scrubbing and polishing machines. WELCH, E. E., 6, High Avenue, Letchworth, Hertfordshire. March 22, 1932, No. 8510. [Classes 60 and 138 (i).] A scrubbing or polishing machine comprises a pad, for example, of sponge rubber, felt, or abrasive material, which is given an orbital movement by means of mechanism driven by a motor, liquid being supplied to the pad from a container, and a suction nozzle being situated at the rear of the pad for removing surplus liquid from the surface being treated. In the construction shown, two pads 22, 23 for use on a carpet are each carried by a structure 36 connected to one end of a bar 24, the other end of which is connected to a pivoted bar 126. Between its ends the bar 24 is formed with a strap surrounding an eccentric disc secured to a shaft 28. The two discs 26, 27 are oppositely arranged on the shaft 28 which is driven from the shaft 32 of an electric motor through a slip clutch device. The shaft 28 is provided with a member 40 forming a cage within which balls 42 run between an upper race 43 and a lower race 44 supported on springs 45. The pressure of the springs forces the balls inwardly against a groove on the end of the shaft 32, so that the shaft imparts its motion through the balls to the cage at reduced speed. Liquid from a container 14 is fed to the pads 22, 23 by means of a feed pipe 50 detachably connected to the container at one end, the other end opening into a valve chamber 52. A float 68 carries on its upper side a needle valve 69 to control the flow of liquid from the pipe 50 and on its lower side a needle valve 70 to control an outlet above the pad 22. A second outlet 71 is adapted to supply liquid by a duct 72 to the pad 23. The flow of liquid through the pipe 50 is also controlled by a valve 74 which in the position shown in Fig. 2 causes liquid to pass through an electric heater 76 before reaching the pads. When the position of the valve 74 is changed the supply of liquid to the pads is shut off while liquid circulates through the heater by way of pipe 78 and outlet 80. In a modification, the heater forms a portion of the main pipe 50 and comprises a heating element provided with a worm which compels the liquid to flow in a helical path. Surplus liquid is removed from the surface being treated through a suction nozzle 16, suction being provided by a fan 18 driven by the motor 12. The fan delivers the liquid through an opening 62 into a container 20 which can be removed from the machine after removal of the container 14. A brush 91 at the rear of the nozzle 16 acts to restore the carpet pile. Each of the pads 22, 23 embraces the sides of the box-like structure 36 and is pressed by springs 38 against the carpet. For scouring purposes the pads may consist of abrasive material such as pumice stone.

Abstract: 1,169,651. Control of motors. COAL INDUSTRY (PATENTS) Ltd. 28 Feb., 1967 [1 March, 1966], No. 8890/66. Heading H2J. [Also in Division H1] A relay for controlling the starting switch of an electric motor is supplied from transformer 6 and has main winding 4 connected to earth through resistor 7 and rectifier 8, whilst exciter winding 5 is also connected to earth through resistor 9 and rectifier 10. When both resistors are in circuit, the relay assumes its holding condition which is interrupted by short-circuiting one of the resistors to operate the relay. A remote starting switch 13 is associated with the resistor 7. Different rectifier polarities can be used to differentiate between motors to be controlled. If exciter winding 5 fails, the system becomes inoperative. In a modification, the resistor 9 is shunted by contacts which are closed when a master motor operates to allow the motor controlled by the relay to be started, these contacts being re-opened after a predetermined time interval. In this arrangement, the switch 13 is dispensed with, a stop switch being connected in series with the resistor 7. A further embodiment employs interlocking contacts in series with the resistor 9. The relay may have two armatures which are set to obtain a differential on release operation. The armatures control normally-open, and normally-closed contacts respectively.

A fan-shaped nozzle for producing an atomized liquid comprises a flat generally fanshaped casing having an elongated rectangular outlet 2 and a tubular attachment part 1 for connection to a compressed air source. A flat segment-shaped body 4 is mounted in the casing such that vertical webs 12 integrally cast with the body extend from the upper to the lower surface thereof, screws 13 being provided to securely attach the lower surface to the bottom ends of the webs 12. The body 4 is formed with open-sided channels 5 in the curved edge thereof which is disposed centrally within the nozzle outlet 2. Each channel is connected to a single source of pressurized liquid through either passages 7, 8 and 11 or 7, 9 and 11. A stop cock 10 is incorporated in the passage 9 in order to stop the flow of pressure liquid to the associated channel 5. The passages 7 are cast in the body whilst the passages 8 and 9, in the form of connectors, are soldered or brazed thereto. The portions of the curved edges of the body 4 defining the upper and lower boundaries of the channels 5 are formed with outlet slits 6 and a curved cover strip 14 of U-shaped cross-section is fixed through a bolt 21 to the curved edge of the body 4. The shape of the strip is such that pressure liquid introduced into the channels 5 is made to pass through the passages formed by the slits 6 between the strip 14 and the body to be directed against the oncoming atomizing air stream through the elongated openings formed between the inner surfaces 16 of the strip 14 and the upper and lower surfaces of the body. The compressed air drives the issuing liquid over the sloping lateral surfaces 18 of the cover strip on to atomizing edges 19 of the strip, by which the sprayed liquid is atomized so that a fine cloud is formed immediately beyond the outlet 2. This opening is surrounded by an edge 23 which projects inwardly and terminates in a sharp edge for directing the compressed air on to the cover strip surfaces 18. The strip may be of such thickness that the edge 23 extends into the flow of the liquid issuing therefrom. The nozzle may incorporate one channel such as 5 or more than two thereof, each channel having independent liquid flow control means associated therewith.
