Title: Improvements in window cleaners
IPC: A47L1/06
Filed: 1950-12-07
Abstract: 692,051. Cleaning windows; scrapers. ALMLOF, J. H. Dec. 7, 1950, No. 29968/50. Classes 61 (ii) and 138 (i). A window cleaner consists of a hand plane device adapted to plane the pane and comprises a thin flexible knife blade carried by a handle and elastic means resting on the upper side of the blade for permitting the blade edge to bend and follow close to the concave shape of the pane caused by the blade pressure during cleaning. As shown in Figs. 1 and 2, a support plate 1 is carried by the handle, the blade 3 is mounted on the plate 1, a rubber or like elastic strip 5 is mounted on the back of the blade and a cover plate 6 is detachably secured by screw-nut devices 4 to the plate 1. In use the rubber strip 5 permits the blade to bend backwardly and so follow closely the curvature of the pane. The upper edge of the plate 6 is bent backwardly and extends beyond the blade edge and so serves as a stopper member to protect the blade edge when the device comes against the window sash. The side edges of the cover plate extend beyond the side edges of the blade and thereby serve to protect the hand of the operator. In a modification, Fig. 5, the side edges (only one, 9, shown) and bottom edge 8 of the cover plate 6 are bent down. The side edges cover the side edges of the blade. When the device is not required for use the cover plate is turned through 180 degrees so that the said bent down bottom edge 8 then covers the edge of the blade.

Abstract: 853,988. Feeding webs. HANDLEY, J. Sept. 19, 1958 [Sept. 28, 1957; Oct. 26, 1957], Nos. 30464/57 and 33464/57. Class 100(1) An apparatus for feeding tape in a step-bystep manner comprises two feed clamps, means for operating the two clamps alternately to grip the tape and move the tape when gripped in the desired direction, means to release the grip of each when returning it to initial position, means for holding the tape stationary during each return movement, an electrically operated relay for each feed clamp, and means for operating each relay to control whether the feed clamp is operative or inoperative to feed tape. Feed clamps 26, 27 are rocked by rollers 51, 52, engaging cams 30, 31 timed so that the clamps feed the tape, not shown, alternately. Tape gripping by anvils 32, 33 is effected by rocking arms such as 53, actuated through a roller 28 by a cam, not shown, co-operating with a spring 57. The roller 28 is prevented from engaging the cam at the appropriate time by the armature 54 of a relay 34. Upon energisation of the relay 34, the armature 54 is - actuated to permit the roller 28 to engage the cam, thereby causing tape feeding by the clamp 27. The clamps 26, 27 feed the tape by energising their associated relays alternately so as to grip the tape alternately. The tape is prevented from moving in the reverse direction by a spring loaded pawl 35 the lower end 48 of which engages the tape. In a modification, Figs. 1 and 2 (not shown) the tape is fed by a single clamp operating in the same manner as in the previous embodiment, the tape being held against movement in the reverse direction by a similar but stationary clamp which grips the tape on the reverse non-feeding stroke of the other clamp.

[Classes 38 (iii) and 38 (v).] A starting device for alternating-current motors, comprises a contact member 1 moved to a starting position shown in Fig. 3, and subsequently biassed to a running position shown in Fig. 2, and an electromagnet 30 carrying the motor current and adapted to provide fluxes of different phase for attracting an armature member on the contact member 1 to retain it in the starting position until the current falls to a value determined by the adjustment of the attractive effect of one of the fluxes. Depression of a button 15, against the action of a spring 17, carries a spring 12 across a dead-centre to rotate contact members 1, 2, about pivots 3, 4 from the position shown in Fig. 2, to that shown in Fig. 3, in which contact member 2 close the motor circuit through resistance. Upon release of the button 15 the spring 17 tends to return the spring 12, and, therefore, the contact members 1, 2, to their original position, but the member 2 is held by a latch 20, and the member 1 by the electromagnet 30. When the member 1 is released it moves to its original position and excludes the resistance. The member 2 is released to stop the motor by means of a button 27 which releases the latch 20. The electromagnet 30 has a core 33, Fig. 4, with a slot in which shading coils 35 are situated, the two polepieces formed by the slot being of different lengths, so that the armature 38 on the contact member 1 is separated from one of them in the attracted position. The electromagnet, which thus produces fluxes of different phases, is adjusted by rotating the core about its axis thereby varying the attractive effect of one of the fluxes.
