Title: Improvements relating to suction cleaners
IPC: A47L5/36
Filed: 1955-03-18
Abstract: 767,647. Suction cleaners. HOOVER, Ltd. March 18, 1955 [March 25, 1954; April 7, 1954; May 14, 1954], No. 8023/55. Class 8(1) A substantial part of the weight of a motor-fan suction cleaner of the canister type is taken by a cushion of air formed by first restricting the fan exhaust by a cupshaped casing member 45 Fig. 1 and then transmitting the superatmospheric pressure thus developed through a blower socket 46 to the space between the underside of the cleaner casing member 45 and the carpet 55 and which is enclosed by a cleaner-supporting skirt 48. The carpet contacting surface of the skirt provides a skid 49 under which the air passes to atmosphere. In a modification the blower socket 61 Fig. 2 is offset from the centre of the end cover 60 and is aligned with an aperture 66 in a top 65 of the skidforming supporting base 62 hinged to the casing 1<SP>1</SP>. The end 60 and top 65 are held spaced apart by bosses 71, 72 provide a bypass such that the cushion of air is sufficient to allow of easy movement of the cleaner casing over the carpet only when the nozzle 43<SP>1</SP> is removed therefrom, resulting in increased air flow. In a further modification the air cushion lifts the skid 148 Fig. 6 from the carpet 157 and the cleaner is maintained stable by a carpet contacting sealing ring 152 capable of vertical movement on guide studs 153 carried by a casing skirt 145 and serving to deflect escaping air through round deodering and filtering material 155 and slots 154 in the skirt 145. In a still further modification the cleaner casing comprises upper and lower hinged hemispherical sections 202, 203 Fig. 10 secured together by a toggle clamp 205 and held by coil springs 292 (only one of which is shown) and ball bearings 263, 261 carried by leaf springs 264 'and brackets 261 respectively within generally hemispherical outer casing members 245, 246 secured together by toggles 252. On pulling the suction hose 238 against the coil springs 292 the cleaner casing portions 202, 203 are displaced relative to the outer casing so that normally aligned apertures 265, 266 in adjacent portions of the lower parts of the inner, and outer casings become blocked thus preventing by-pass of fan exhaust through an annular passage 272 and forcing it through the hose socket 286 to the cushioning space from which the air escapes under an annular skid 275. In a further modification by-pass apertures 351, 373 Fig. 12 in the cleaner casing 203<SP>1</SP> and a valve disc 370 respectively are moved out of register by a pedal 375 so as to force the fan exhaust through the blower hose socket 286<SP>1</SP> to the cushioning space when it is desired to move the cleaner about the carpet. The invention is also applicable to a cleaner of the horizontal cannister type.

Title: Resilient device for fixing railway rails to sleepers
IPC: E01B9/30
Filed: 1948-03-18
Abstract: 652,305. Securing railway rails. USINE DES RESSORTS DU NORD. March 18, 1948, Nos. 8076 and 8077. Convention dates, April 5, 1947, and Jan. 2, 1948. [Class 104 (ii)] A resilient device for fixing railway rails to sleepers comprises a spring-metal blade bent over and around to form an eye 1 and two superposed arms 2, 3 of unequal length, both arms being provided with a hole 4 through which a securing bolt 9, or a coach screw, is passed when the fastener is positioned with the longer arm 2 seated upon the flange 7 at one side of the rail and the end of the shorter arm 3 in abutment with the edge b of the flange, the eye 1 being seated within a recess or hollow 12 of corresponding shape provided in the sleeper 6. The bolt-holes 4 are of larger diameter than the bolt to permit the arms to be moved slightly into the clamping position when the bolt is tightened. A capping member 13 is preferably interposed between the upper arm 2 and the nut 11 so that when the latter is tightened initially the end of the arm exerts pressure at a part 15 of the flange near to the web 16, and with further tightening the arm becomes curved and abuts against the edge 17 of the flange. A strip 8 of rubber or other flexible or resilient material is preferably interposed between the sleeper and the base of the rail. The cross-section of the metal strip may decrease continuously from the lower to the upper arm. A bushing or bearing strip may be inserted in the recess 12 in the sleeper, the material of the strip being metal or a plastic or resilient material such as rubber. The bearing strip has diametrical lugs for securing it to the sleeper, e.g. by welding when strip and sleeper are both metal. In a modification, Fig. 5 (not shown), the upper arm of the clamping strip has its end inturned reversely and upwardly where it bears on the flange of the rail.

Title: Improvements in or relating to thread guide feed devices for cop winding machines
IPC: B65H54/14
Filed: 1941-06-27
Abstract: 549,860. Winding yarns. SCHARER, K. J., (trading as MASCHINENFABRIK SCHARER). June 27, 1941, No. 8097. Convention date, June 5, 1950. [Class 120 (ii)] In a cop-winding machine in 'which the thread guide is carried by a reciprocating rod and is moved there along to build the cop by a feeler member engaging a rod partly threaded around its circumference, the feeler member towards the end of its traverse meets a stop member on the threaded rod which is then moved longitudinally and rocked to release the threads from engagement with the feeler member and permit the latter to be returned to its initial position where it abuts a second stop member on the threaded rod and moves it longitudinally in the opposite direction so that it is rocked to reengage the feeler member with the threaded rod. As shown the thread guide carrier 5 is carried by a sleeve 3 which is coupled to the reciprocating traverse rod 1 by a cone and ball clutch 8 and spring 7. The carrier 5 slidably engages a sleeve 12 of the feeler member threaded to engage the partly threaded rod 16 and carrying the feeler member 10 and the rod 16 carries a pin 21 engaging a helical slot 20 inastationary bushing 19 in the support 2. When the initial portion of the winding attains a certain diameter the feeler member contacts therewith and is rotated slightly so that it and the sleeve 12 moves along the rod 16, contacts with the carrier 5, and, by overcoming the spring 7, moves the carrier slightly along the traverse rod 1. As the winding nears completion a slide 25 is moved so that a projection 25<SP>1</SP> thereon meets a pin 30 on the carrier 5 and moves it against a flange 13 on the sleeve 12 which then strikes an adjustable stop 22 on the rod 16 and moves it longitudinally; the engagement of the pin 21 with the slot 20 causes the rod 16 to rock and disengage its threads from the threads of the sleeve 12 which is returned to its initial position by the slide 25 which also carries a pivoted catch 27 which has engaged the pin 30 on the carrier 5. As the slide 25 approaches the initial winding position a nose 28 on the catch 27 strikes a stud 33 and the catch is disengaged from the thread carrier while the feeler member 10 strikes a second adjustable stop 23 on the rod 16 and causes it to be again rocked to engage the threaded sleeve.
