IPC: H01H3/46
Filed: 1922-12-08
Abstract: 209,268. British Thomson - Houston Co., Ltd., (General Electric Co.). Dec. 8, 1922. Oil-switches; actuating.-In switches employing a collapsable toggle mechanism permitting separation of the contacts, the initial opening movement of the operating mechanism stores up energy which causes the collapse of the toggle mechanism independently of further movement of the operating mechanism and assists the forces tending to separate the contacts. As applied to an oil switch, the rectilinearly moving operating rod 17 is forked at its upper end 16, each limb having a slot 26 in which is located a pin 18 on the end of one arm of a bell-crank lever 13 pivoted at 21, the other arm of which constitutes one of a pair of toggle members 12, 13. The toggle arm 12 is pivoted at 15 to a lever 9 pivoted at 9<a> and attached to the switch rod 8 which carries the bridging member 6 and is surrounded by the opening spring 24. A second spring 19 acts between a pin 20 at the upper end of the rod 17 and a pin 28 on the bell-crank 13. The setting of the toggle 12, 13 is limited by an adjustable stop 22. In opening the switch the initial downward movement of the rod 17 merely strains the spring 19 until its energy is sufficient to break the toggle 12, 13 when the switch opens independently of the operating mechanism under the combined action of springs 19, 24. The spring 19 ensures that the pin 18 reaches the lower end of the slot 26 at the end of the opening movement, so that the toggle linkage is actuated at the commencement of the closing stroke.

Abstract: 849,665. Winding thread. REINERS, W. Nov. 7, 1956 [Nov. 9, 1955], No. 33996/56. Addition to 830,978. Class 120(2). In an automatic bobbin changing thread winding machine having a winding spindle head with means for mounting a bobbin thereon, a thread gripping device, and means to present the leading thread end portion to said device before commencement of rotation of the spindle head, the said gripping device comprises a member mounted on the spindle head so as to engage the thread end when the spindle commences to rotate and hold it pressed against the head which member is resiliently deformable under centrifugal action to release the thread end before the spindle reaches its normal operating speed and means to deflect the released end into the path of the thread approaching the bobbin so as to be wound into the thread turns being formed on the bobbin. As shown, the spindle head 1 is provided on its outer end with a collar 101 formed with a rearwardly projecting nose 101a which overlies the free end 102a of one arm 102 of an L-shaped or hook shaped member 104 secured to the spindle head by bolt 106. In operation the thread F leading from a thread guide (not shown) by way of a clamping device (not shown) to a full bobbin (not shown) is positioned in the path of the nose 101a so that when the spindle head carrying an empty bobbin commences to rotate the thread is engaged by the nose and slides along the edge 101b and becomes engaged and gripped by the arm 102 so breaking the thread. As the speed of the spindle head increases the arm 102 is forced under centrifugal action away from the base of recess 1a so that the end portion 107 of the thread is released. The released end 107 is then caused, under centrifugal effect to slide along the edge 103 of arm 102 and be drawn out from beneath the arm 102 and become wound in the thread turns being formed on the bobbin.

Filed: 1965-08-09
Abstract: 1,114,042. Air heating furnaces. CALMAC MANUFACTURING CORPORATION. 9 Aug., 1965 [12 Aug., 1964], No. 34071/65. Heading F4S. A domestic hot air furnace is gas or oil fired and provides high velocity air at a temperature of 250-375 F. As shown, the combustion gases 17 of gas burners 12 pass upwardly through cells 16 to exhaust ports 36. Air to be heated enters the furnace through a filter 48, passes up through a chamber 52, through a humidifier 56 and downwards through narrow passages 58 defined by baffles 84, 85 adjacent to cells 16, where it is heated, and into a suction plenum chamber 42. A blower (not shown) maintains the pressure in plenum chamber 42 below atmospheric pressure and forces the air to narrow distribution ducts. The side walls of the furnace comprise an insulation layer 76 (e.g. glass fibre lined with aluminium foil) and, spaced therefrom, a metal covering 74 defining a narrow passage 80 communicating with the plenum chamber 42 at its lower end and the atmosphere at its upper end. Air drawn down passages 80 into the plenum chamber aids the cooling of the walls of the furnace. Should the blower fail, the fuel supply is stopped by a pressure sensitive switch in the plenum chamber, and the heat of the air within the furnace is safely dissipated through a heat trap and radiation box 54. A hot water heater 132 (Figs. 6, 7, not shown) may be incorporated inside the furnace adjacent the cells 16 and heated by air blown from plenum chamber 42 by a fan 148 and passing to the space above cells 16.
