Filed: 1959-08-11
Abstract: 880,430. Polishing pads; floor polishing machines. CLEMENTS Ltd., A. E. Aug.11, 1960 [Aug. 11, 1959], No. 27488/59. Classes 19 and 138(1) A floor polisher comprises a body 1, a reservoir for polish, a lip 33 movable between a retracted position in which it is in contact with the polish and an extended position in which it is in contact with or close proximity to the floor, a handle connected to the body and capable of limited movement relative thereto, and driving means connecting the handle and lip to cause the lip to move from one position to the other position, when the handle is moved relative to the body. As shown, the body is in the form of a shallow tray having a dividing wall 11 and spaced apart lugs 12, 13 engaged by hooks 15 on a cover 14 slidable longitudinally with respect to the body. such movement of the cover being limited in one direction by a screw 16. A catch 20 carrying a cam 21 which coacts with a pin 22 prevents sliding movement of the cover. A pivoted handle 23 enables the polisher to be moved back and forth over a floor. A pair of arms 26 passing through notches in the wall 11 are connected to the cover 14 by pins 31 and are notched to receive the cranked ends of a rod 39 mounting a strip 33 of rubber. A brush 41 enclosed by a hinged cover 34 carries on the axles thereof ratchet wheels 42 engageable by pawls 44. In operation, the brush is loaded with polish and placed within the cover 34 and movement to and fro of the polisher causes the cover 14 and arms 26 to reciprocate whereby the pawls 43 rotate intermittently the brush 41, the strip 33, when the cover moves away from the wall 11, being retracted to wipe polish from the brush; movement of the cover towards the wall causes the strip to be projected into contact with or in close proximity to the floor. To transfer polish to the floor, on the base of the tray is a polishing cloth 48 held in position by a pivoted frame-work 46, and a layer 49 of felt. Specification 829,550 is referred to.

Abstract: 451,164. Proofing permeable materials; treating wood. BOLIDENS GRUVAKTIEBOLAG, 17, Võstra TrÓdgÓrdsgatan, Stockholm. Oct. 7, 1935, Nos. 27678, 27679, and 27680. Convention dates, Oct. 8, 1934, Feb. 9, 1935, and March 12, 1935. [Class 140] Wood and other permeable materials are rendered rot-proof by impregnation with two reacting solutions in succession. The wood &c. is heated in the first solution to a temperature of about 100‹ C., which is maintained for a period, after which the solution is cooled, for example to 70-80‹ C., so that the solution is absorbed, and the material is then treated with the second solution at a temperature of, for example, 10-20‹ C., whereby a difficultly soluble precipitate is formed. The first solution may contain a soluble arsenate, e.g. sodium arsenate or arsenite or arsenic trioxide. The second solution may contain alkaline bichromate or soluble copper, zinc, manganese, calcium, barium or magnesium salts, e.g. chlorides or sulphates, or mixtures of two or more of such salts. A tank A is loaded with material 12 and filled with the first solution which is rapidly heated by circulation through a boiler G, a pump 6 and pipes 7, 8. After four to five hours circulation through the boiler is stopped and cold solution from a tank C admitted. Uniform cooling is effected by pump circulation, the boiler G being byepassed by closing valves 11 and opening valve 10. When impregnation with the first solution is complete, the material is transferred to a tank B containing the second solution fed from a tank D. Meanwhile a fresh batch of material is being treated in the tank A. After each impregnation sufficient solution is added to tanks A and B from tanks C and D to replace that absorbed. In a modification of the apparatus three impregnating tanks and a second pump are provided so that the steps of the process can be carried out in uninterrupted sequence.

Title: Improvements in a walking toy or the like
IPC: A63H11/04
Filed: 1952-11-10
Abstract: 716,949. Walking, and magnetic toys. WIGAL, V. F. Nov. 10, 1952. No. 28253/52. Class 132(3) A walking toy has # feet " adapted to attach themselves to the surface on which the toy is to walk and arranged so that under the influence either of propelling means carried by the toy or of the weight of the toy they are moved successively through positions in which they attach themselves to the surface, each foot remaining attached to the surface until the next one has attached itself thereto so that at least one foot is always attached to the surface. In Fig. 1 a representation of a woodpecker has star wheels 6 with spokes 7, and at the outer end of each pair of spokes a suction cup #foot " 11 is pivotally mounted, the wheels 6 being rotatable by a clockwork mechanism which may have an escapement to produce a clicking sound. With the mechanism wound, the toy is. pushed against a surface 14 and at least one cup 11 adheres thereto. The wheels 6, turn, causing the tail 2 to engage the surface 14 and the next succeeding cup to bebrought into engagement with the surface. Each cup 11 when out of engagement with the surface 14 is caused to pivot by a rubber strand 16 such that as the cup approaches engagement with the surface, the cup and surface are substantially parallel to one another. Continued rotation of the wheels 6 causes the first cup to be forcibly removed from the surface and another cup to engage the surface, an intermittent movement of the toy thus being produced. The cups may have bendable shanks, Figs. 8, 14, (not shown) and to control the time required to pull the cups away from the surface, each may have a bleeder passage, Figs. 13 and 16-25, (not shown). In Figs. 10, 11 (not shown) the toy moves over a surface under the force of gravity and in Fig. 5 (not shown) two helical springs provide the motive power. Propulsion may alternatively be by electric motor. For use on appropriate metal surfaces magnets 27, Fig. 7, may be used in place of the cups, Fig. 7, and may be provided with a layer of friction material to assist adherence between the magnets and the surface. It is stated that the mere use of a substance of sufficient stickiness on the " feet " of the bird is sufficient as a means of adherence to the surface to be travelled on. The #feet " may be arranged on an endless track or chain 'or on the legs of a toy simulating the walking action of a biped of which the legs may have suction cup # feet " and be pivoted together at their mid-lengths by sliding pivots journalled in the body of the toy. The legs are fixed at their upper ends to cranks turned by a source of power.

Filed: 1928-10-03
Abstract: 321,782. Withers, J. S., (Koehring Co.). Oct. 3, 1928. Scoop-arm machines; grab machines.-In excavating and like apparatus capable of conversion from the dipper to the grab-bucket type, the line F, which is used for tripping the dipper latch or as a tag line for preventing twisting of the grab, is wound on a drum 10 rotating on a hollow boss 11 in a casing 12 pivoted at 14 and surrounding a disc 15 rotating on a fixed axis; the casing is adjustably secured by a bolt 25 to an operating lever 18 passed by a spring 27. When the cable F is used for tripping the dipper latch, the bolt 25 is adjusted so that the drum lightly engages the member 15 at point x so as to be frictionally driven to take up slack, tripping of the dipper latch being effected by the lever 18. When the cable F is a tag line, the bolt 25 is adjusted so that the greater-frictional drive necessary for the drum is effected at the point y. Alternatively, the greater frictional drive required for a tag line is provided by turning down a latch 27<a> to hold the lever 18 in a suitable position.
