Title: A new or improved machine for filling mattresses and the like
IPC: B68G7/05
Filed: 1932-03-23
Abstract: 387,856. Mattress-stuffing machines. CROWN BEDDING CO., Ltd. and WALLIS, L. S., 46, Macdonald Street, Birmingham. March 23, 1932, No. 8597. [Class 52 (iv).] The stuffing-material for a mattress &c. is assembled between a lower surface and an upper hinged surface both formed of slats, and the upper surface is then swung down and held, and the whole is pressed into the mattress casing through a nozzle over which the casing is placed. The slatted receptacle slides on a table top between adjustable side walls, and is actuated by a pneumatic or hydraulic ram situated beneath the table. Fig. 1 is an elevation and Fig. 2 a plan of the machine. The table 1 is supported on legs 2 and the side walls 3 are adjustable across the table top by right- and left-hand threads on shafts 5, 6 geared together by chains and operated by hand wheels 7. The slotted receptacle comprises horizontal slats 22, and hinged slats 23 both carried by detachable blocks 21 attached to a crosshead 20. The cross-head is connected by brackets 19 to a carriage 14 which has rollers running on rails 15 beneath the table. The plunger of a pneumatic cylinder 9 carries two pulleys 10, and a cable 11 secured at one end 12 is reeved round one pulley 10, round a fixed pulley 13, through the carriage 14 to which it is clamped, round another fixed pulley 16, and round the second pulley 10 on the plunger, its other end 17 being secured to the frame. The stroke of the plunger is thus half the travel of the carriage 14. When the stuffing-material has been assembled on the slats 22 and between the side walls 3, the hinged slats 23 are swung down and are held by a cross member 25. This member is pivoted on a shaft 24, and when it is turned down from the vertical position shown, is held in a horizontal position by a spring 27 attached to an arm 26 on the shaft 24. The empty mattress casing is then placed with its open end over the nozzle 31 and tucked up thereon. Air is admitted to the cylinder 9 by a valve 32, and the cross-head 20 in its advancing movement pushes the slatted receptacle with its contained stuffing material into the empty casing. When the casing is full, it is held by an operator while the slats are withdrawn by reverse movement of the cross-head. The valve 32 admits air to operate the plunger, and also controls the escaping air so that the rate of movement is substantially constant despite variations in resistance. The stuffing-material may form a padding on each side of an enclosed spring centre.

Title: Improvements in or relating to electrical distribution systems and protection thereof
IPC: H02H7/04
Filed: 1947-04-01
Abstract: 622,605. Protective cut-out systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 1, 1947, No. 8796. Convention date, Feb. 20, 1946. [Class 38(v)] In a distribution system in which the secondary windings of transformers are interconnected, each transformer has two thermally tripped overload circuit breakers associated with it, so that on the occurrence of a fault, only the faulty interconnection is disconnected from the transformer. In Fig. 1 a liquid immersed transformer has circuit breakers 12, 13 submerged in the liquid. Each circuit breaker has two thermal elements 14, 15, either of which, by releasing spring-loaded linkage, can trip open the main circuit breaker contacts 17, 53, 18, 54, and close auxiliary contacts 72. 73 to light a signal lamp 16. In the system of Fig. 2, transformers 81-83 supply interconnected feeders 84-87 and each circuit breaker 12, 13 is connected so that one of its thermal elements 14', 15 is responsive to the full load of the transformer, whilst the other, 14, 15' is responsive to the load in the feeder controlled by the circuit breaker. Assuming a fault on line 95 of feeder 85, the fault current would flow through thermal elements 14, 14' of the circuit breakers of transformer 82. This would result in the tripping of only the circuit breaker 12 of this transformer, as element 14 operates at a lower current or temperature than element 14<SP>1</SP> and in addition it carries the fault current supplied from transformer 81. The fault current from transformer 83 flows only through element 14<SP>1</SP> of the circuit breaker 13 of that transformer, so that this circuit breaker trips to isolate the feeder 85, and the transformers 82, 83 continue to supply their other feeders. In a modification Figs. 3, 4, (not shown) the thermal elements 14, 15 of each circuit breaker 12 are both responsive to the total load of the transformer, while those of each circuit breaker 13 are responsive only to the load supplied to the feeder it controls, the operation being fundamentally the same.
