Title: Improvements in or relating to machines for winding coils for electrical devices
IPC: H02K15/04
Filed: 1934-07-26
Abstract: 446,415. Coil-winding apparatus. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(General Motors Corporation; West Grand Boulevard, Detroit, Michigan, U.S.A.) July 26, 1934, No. 21934. [Class 35] A machine for winding coils such as those described in Specification 358,073 is provided with means to anchor the wire to the winding head and, when the coil is complete, to sever the anchor at the bend, thus avoiding waste by severing it at a distance from the anchor, at the same time severing the trailing end of the wire and forming an anchor for the next coil; means for operating the winding head are also described, as are the winding groove, and means for guiding the wire which are identical with those described in Specification 446,464. The wire passes through a slot 266, Figs. 12, 13, and 14, in the winding head 200 and the bending, and cutting blades 247 work in a slot 265. One of the blades 247 is furnished with a single cutting edge 271 for severing the trailing end of the wire. The other is formed above with a blunt edge 272 at a slight distance from the wall of the slot 265 so as to leave room for the end of the wire to be bent round into an anchor as shown. This blade is formed below with a cutting-edge 273 which severs the anchor of the previously-formed coil. The two edges are separated by a tooth 274 which preserves the freshly-formed anchor from being severed by the edge 273. When the blades are retracted after forming the anchor and severing the wire, the tension of the wire brings the anchor below the tooth 274 so as to be severed at the next motion of the blades. The head 200 and blades 247 are carried on a shaft 212 driven through a clutch 224, Fig. 2. The shaft 212 drives through pawls a countershaft carrying cams which, when the shaft 218 has made a sufficient number of turns, disengage the clutch 224 against a spring 213 and cause a hook 240 to engage a notch in a disc 225 on the shaft 225 so as to stop the shaft. The head 200 consists of two interlocking parts one carried on the shaft 212 and one on a longitudinally slidable shaft 218. When the coil has been wound and the shaft stopped as described a pedal 221 is depressed which, through the linkage shown, first moves a sliding cone 246 on the shaft 212 to operate the blades 247 and then causes the shaft 218 to move endways to disengage the two parts of the head 200 and release the formed coil. On releasing the pedal 221 a spring 251 returns the parts to their former positions and a pawl carried by the cone 246 turns the countershaft so as to release the hook 240 and the clutch 224, which is then re-engaged by the spring 213.

Abstract: 620,596. Liquid-fuel burners. MEIER, J. July 24, 1946, No. 22107. Convention date, Aug. 1, 1945. [Classes 75(i) and 75(iii)] In a liquid-fuel burner having a rotary cup with an out-turned rim a stream of air, additional to the streams of air passing through and over the rotary cup, is delivered into the combustion chamber through ports lying outside the rotary cup and impinges against a stationary radially directed wall so that it is directed radially outward towards the wall of the combustion chamber. A fan 3 mounted on the shaft 2 of the rotary cup 4 forces air along the inside of the cup and also through an annular gap 10 surrounding the cup. A further stream of air from the fan is forced through holes 11, 12 arranged in circles around the shaft 2 and is directed radially towards the wall 8 of the combustion chamber by impinging on a stationary radial wall 8a. Liquid-fuel from a pump 5 is delivered into the cup through the open end of a pipe 6. The fan, fuel pump and rotary cup are driven by an electric motor 1. The burner is ignited by an electric sparking device 30. The Specification as open to inspection under Sect. 91 states that the outer face of the rotary cup is stepped and also describes a construction in which two ignition devices are arranged on a common ring plate which functions in the same way as the stationary radial wall 8a. This ring plate may rest on springs to allow of its displacement. This subject-matter does not appear in the Specification as accepted.

Abstract: 630,047. Extruding earthenware pipes. CLARKS POTTERIES, Ltd. Aug. 13, 1947, No. 22553. Convention date, Sept. 13, 1946. [Class 87 (ii)] An earthenware pipe extrusion machine for producing gully trap pipes or other pipes having bends has a movable deflector plate within the extrusion chamber operated by lever means, so as to restrict the flow of clay towards whichever side the plate is moved, and thus form bends in the pipe. The upper part 1a, Fig. 1, of the extrusion chamber, having the flange 1d by which the apparatus is connected to the clay-forming apparatus, supports the core 5 by means of bridges 6 and core stem 7, and co-operates with the lower part 1b of the chamber, providing journals 10, 10a for spindles 9, 9a. The hand-lever 12, Fig. 5, moving over the quadrant 13 between stops 14 rotates the spindles and their attached bridges 8, 8a which rock the arms 15, 15a fixed to the deflector plate ring 16 positioned concentrically to the groove 7a in the stem 7. The deflector plate is thus moved laterally across the extrusion chamber. In the extrusion of a socketted pipe, a vertically movable table 18, Figs. 1, 5, supports a socket core 19 in engagement with the core 5, and hinged socket mould parts 20a, 20b are clamped together around the orifice of the die 4, and supported on the raised table by means of adjustable set screws 26. When the socket has been moulded the parts 20a, 20b are swung clear of the die orifice on a hinge pin 22 and the extrusion of the pipe continued. By movement of the hand-lever 12 the deflector plate may be caused to regulate the flow of material to one side or the other of the die 4 and produce pipes of desired contour and regular wall thickness. The rim of the die 4 and the flange 1e to which the die is secured are cut away as at 1f to permit the flange of an extruded bent pipe to clear the outer side of the extrusion chamber.
