Patent GB-429106-A (GB)
Title: Improvements in or relating to odorising and like devices for association with suction cleaners
IPC: A47L7/04
Filed: 1933-11-24
Abstract: 429,106. Suction cleaners. HOOVER, Ltd., Perivale, Greenford, Middlesex.- (Hoover Co. ; North Canton, Ohio, U.S.A.) Nov. 24, 1933, No. 32855. [Class 8 (i)] A reservoir for an odorizing agent is mounted on a suction cleaner in communication by way of a valve-controlled duct with a passage in the cleaner through which air flows when the cleaner is in use, the valve being closed when the cleaner is out of use but delivery of odorizing agent therethrough is effected automatically as the result of a movement of the cleaner when brought into use or as the result of some change of condition in a part of the cleaner which occurs during use. In Fig. 1 a cylinder E<1> in communication with a reservoir E5 containing an odorizing paste, contains a spring-controlled plunger F. The starting of the suction motor activates the solenoid F<1> and the consequent downward movement of the plunger F delivers a supply of paste past the spring-controlled ball-valve E<3> to the passage c through which an air-stream flows. In Fig. 2 a supply of powder is contained in a reservoir G<1> the throat of which is closed by the spring-loaded valve G<3>. The airsuction set up by starting the cleaner is communicated to the pipe H<1> and raises the valve G<3> whereupon a supplementary air stream flowing from atmosphere through the byepass H<2> carries powder with it. In Fig. 3 rise of temperature of the motor A during operation of the cleaner causes bimetallic strips L to flex and force down the pistons J<2> to deliver a supply of odorizing paste past the spring-loaded valve K<1>. The thermallycontrolled element may take the form of a disc which buckles with a snap action on attainment of a predetermined temperature and this arrangement may be employed to reset mechanism for delivering a predetermined quantity of odorizing agent when the temperature of the motor rises above a predetermined value. In another form the movement of the handle o, Fig. 6 to the operative position moves a stud o<3> and allows a bolt P to move forward under the action of a spring P2. A charge of odorizing agent which was in the cylinder R in front of the piston R<1> is thereby discharged past a ballvalve into the air-stream.

[A Specification was laid open to inspection under Sect. 91 of the Acts, May 22, 1948.] [Class 140] [Also in Group XIII] Heat-insulating material (Fig. 1) comprising a loose, porous mass 4 of rock wool or the like between two sheets 2, 3 of paper with flanges 5 glued together has threads 6 of glue extending through the mass 4 to hold it in position. The paper sheets 2, 3 are fed from rolls 7, 8 (Fig. 3), and are coated with glue by rollers 12, 15 respectively, the under-sheet then travelling along a table 20 of trough-shaped section and receiving the porous mass on its glued surface before passing under a glue-extruding device to receve the glue threads 6. The upper sheet 2 is then applied and the united sheets are fed forward by pressure rollers 18, 19 and wound on a roll 10. Glue may be applied over the whole surface of the upper sheet 2 or confined to the edges, whereas the edges of the undersheet are left unglued. The table has ledges 21 (Fig. 4), overlying the edges of the sheet to produce the side flanges 5, and between a guide roller 13 and the pressure rollers these ledges are replaced by electric heaters 55 to dry the glue. The material is given its final form by the pressure rollers (Fig. 6), the centre part of the roller 18 being freely rotatable on its shaft. Extruding device.-Journalled in stands 22 (Fig. 4), is a shaft 25 arranged transversely to the table and carrying a frame 26 which itself carries the cylinders of piston pumps 27. Rods 28 connect the frame 26 to eccentrics 29 on a shaft 30 (Fig. 3), rotated at constant velocity. A frame 31 guided by T-shaped grooves 32 in the frame 26 has two arms (Fig. 4), which engage flanges on eccentric discs 34 on a hollow shaft 35 rotatable on the shaft 25 and driven from the shaft 30. From the frame 31 depend the piston rods 38 of the pumps 27, each rod being screwed into a hollow piston head which carries a hollow needle 41. A passage closed by a non-return valve leads from the cylinder cavity into the piston head. Glue is fed to the pumps (Fig. 3), on opening a two-way cock 48, by a flexible conduit 49, a manifold 50 and branch conduits 51, each containing a non-return valve 52. As the shaft 30 revolves, the frame 26 oscillates longitudinally of the table and the reciprocatng frame 31 oscillates vertically. During the downward movement of the frame 31 glue enters the pumps and is extruded through the hollow needles as this frame moves upwards. The pumps are cleaned by reversing the two-way cock and passing a soda solution through the device. For producing a material of modified cross-section both pressure rollers may have the shape of roller 18.
