摘要： 574,104. Electromagnetic switches. BROOKHIRST SWITCHGEAR, Ltd., KNOWLES, J. O., and HARRIS, R. C. Jan. 1, 1944, Nos. 19 and 14415. [Class 38 (v)] A multipole contactor, suitable for motorstarting, comprises a pair of fixed contacts 15, 16 per pole arranged radially about the pivot pin 14 of a movable fan-like part 21 slotted at 25 to house spring-loaded, floating bridging contacts 26. The fan 21 is attached by the link 24 to the armature 23, the whole moving as a balanced unit about the pivot pin 14. A switch 20 is manually operated by push button 34 to cause a spring blade 35 to bridge contacts 36 and energize the electromagnet 19 thereby attracting the armature 23 which bears against the spring plunger 37, so holding the switch 20 closed. The contactor is opened by pushing the knob, whereby rod 43 lifts blade 35 clear of contacts 36. Modifications include positioning of the contacts in a different construction of support, comprising a moulded housing between the side walls of which the fan moves, Figs. 3-5 (not shown). Stop and start buttons may alternatively be used, together with anti-single phasing devices, Figs. 6-8 (not shown).

摘要： 417,686. Milling-machines. HERBERT SIR A., LLOYD, A. H., and JINMAN, C. H., c/o Herbert, Ltd., A., Canal Road, Edgwick, Coventry. July 5, 1933, No. 19060. Addition to 393,380. [Class 83 (iii).] A milling or like machine tool according to the parent Specification is modified by the provision of means associated with the table and spindle drive whereby the spindle is automatically disconnected at a predetermined table position, preferably at or near the end of its forward travel so as to prevent the work being damaged by the tool during the return movement. As applied to the machine shown in Figs. 7-10 of the parent Specification, the spindle drive includes a clutch 12 operated through a lever 15 connected with lost motion at 16 to a rod 17 hinged to a crank 18 on the hand control lever 14. To engage the clutch the hand lever is raised, whereupon the end 19 of the lever 15 is held against the force of a disengaging spring 21 by a latch lever 20 which is biassed into latching position by a spring 24. When the hand lever is released the lost motion connection allows it to return towards the clutch disengaging position wherein a cam portion 22 engages the top of the latch part 23. A slight pressure on the hand lever moves the rod 23 downwards and disengages the latch, whereupon the spindle clutch is disengaged and a brake (not shown) applied to the spindle. For automatic release of the latch mechanism a Bowden cable 25 is actuated from a striker 28 on the table through a bell crank 27, this action being preferably timed to occur just before the switching means disconnects the feed drive to allow the motor to return the table so that the work cannot be damaged. In a modification, Fig. 4, the rod 17 is moved to the left by the hand control lever to engage the clutch, which is held in against the pressure of a disengaging spring 21 by a pivoted latch 20, the latch being disengaged against a spring 24 either by the hand lever acting through the boss 29 on the rod 23 or by Bowden cable 25 operated automatically from the striker 28 on the table.

摘要： 416,153. Chucks. HERBERT, SIR A., LLOYD, A. H., and JINMAN, C. H., c/o Herbert, Ltd., Canal Road, Edgwick, Coventry. June 14, 1933, No. 16955. [Class 83 (iii).] In an electrically operated chuck the jaws are actuated through bell-crank levers or other means, (not shown), controlled by a push rod 31 secured to a nut 28 splined at 30 within a lathe &c. spindle 12. The nut 28 is engaged by a screwed spindle 29 rotatably mounted within the spindle 12 by means of roller thrust bearings 26 located between roller journal bearings 27 and carrying an annular gear 24 meshing with floating pinions 22 which also engage an annular gear 23 secured to the spindle 12 through a casing 13. The stator casing 15 of an electric motor is secured to the casing 13 to rotate with the spindle 12 whilst the rotor 19 is mounted in bearings 20 in the casing and carries a pinion 21 engaging the pinions 22. The annular gears 23, 24 have slightly different numbers of teeth so as to provide a reduction ratio of about 70 to 1. The spindle 29 has a quick-pitch screw thread of about three threads per inch and is non- reversible so as to maintain the clamping pressure on the jaws. To provide a yielding telescopic connection between the push-rod 31 and the jaws, a sleeve 37, Fig. 2, may be attached to the rod 31 and provided with a collar 38 engaging springs 39, 41. These springs act on a push-rod 36 rigidly connected to the jaws, through a collar 40 on the rod and a sleeve 42 secured to the rod by a pin 43 slidable in a slot 44 in the rod 31. When applied to a small lathe, the bearings 27 are replaced by a plain journal bearing and the bearings 26 by two ball thrust bearings acting on opposite sides of a collar on the spindle 29 located at one end of the plain bearing, and within the bearing for the lathe spindle 12. Current may be supplied to the motor through brushes 32 and slip-rings 33, arranged either as shown or on the periphery of the stator, control being effected by a switch on the lathe headstock connected with electromagnetic contactors on an auto-transformer arranged away from the lathe. The tappings of the transformer maybe used to vary the engagement pressure of the jaws on the work. Alternatively, a polyphase resistance in series with the stator winding may be used, or the motor might be a series-wound direct current motor controlled through a variable resistance. The motor is controlled by a double-acting switch which is biassed to the " off " position so that it may be held by the operator in either position until the jaws have either opened or closed and the motor has stalled, whereupon on release of the switch it returns to the " off " position.

摘要： 391,634. Artificial limbs. DAVIES, C. H., 1136, Girard Avenue, Philadelphia, U.S.A. June 20, 1932, No. 17342. [Class 81 (ii).] A hollow metallic artificial limb member is formed by working in stages upon a flat or curved sheet of thin metal, such as aluminium or alloys thereof, to produce a one-piece seamless tubular element, closed at one end, and then shaping this to the configuration of the limb. The metal sheet is spun or compressed over mandrels of progressively diminishing diameter until it assumes first a basin-like form and finally the form of a tube d, having coaxial zones of different diameters along its length. By spinning or compressing over a tapering mandrel f, the open end may be caused to conform to the shape of the limb stump and the tube assumes the form indicated at e. If the limb is to be used, however, with a socket member fitting the stump, shaping of the open end is unnecessary The element d or e is now bent or distorted to correspond with the shape of the limb and is expanded to that shape in a mould. The mould may be a composite one formed of main mould sections and interposed shim mould sections to form a mould of the required length as described in Specification 383,230, [Group XXII], and the expansion may be effected by water pressure as described in Specification 383,231, except that the fluid is introduced through one end only. The mould is shaped to form a V-shaped groove in the knee end for accommodating a check cord and, in the opposite surface, a recess i, the ends of which co-operate with a stop on the inner surface of the front part of the shim element to limit the extent of movement. Projections k may also be formed through which holes are bored for the pivot bolt which may be fitted with ball bearings. A covering, for example, of artificial cellulosic material or a plastic material with a nitrocellulose or cellulose acetate base, may be applied as described in Specification 383,231. For example, a softened tube of the material may be stretched over the limb and allowed to contract and harden. The colour may resemble natural skin.

摘要： 383,229. Artificial limbs. DAVIES, C. H., 1136, Girard Avenue, Philadelphia, U.S.A. June 30, 1932, No. 18501. Convention date, July 3, 1931. [Class 81 (ii).] An artificial limb socket member is formed from a tube of artificial cellulosic material or plastic material with a nitrocellulose or cellulose acetate base by softening it with heat or a solvent expanding it to conical form 5 and then shrinking it on to a plaster cast 3 of the stump. The socket may be reinforced by wrapping it with a fabric material known as " Cellastic." The top is turned over at 7 to facilitate attachment by rivets 13 to the metal shin 11. A wrapping D of " Cellastic " prevents movement at the bottom.

摘要： 19,603. Crompton & Co., and Harris, R. C. Sept. 28. Cut-outs.-Electro - magnetic means for tripping electric circuit-breakers, on the occurrence of reverse current or overload, either on continuous or alternating current circuits, described in connexion with the circuit-breaker of Specification No. 26,856, A.D. 1903, consists of a moving coil, connected in shunt with the main circuit or independently supplied with current, and lying below the poles of an inverted horseshoe magnet excited by a series or compound coil on one limb. The coil is carried by a pivoted frame provided with adjustable weights or springs to regulate its action. In the form shown in Figs. 3 and 4, the apparatus has a U-shaped core B fixed to the base - plate of the circuitbreaker, an exciting-coil A, and a thin nearly-flat coil D wound on a non- magnetic frame which is carried by two rods E pivoted at their upper ends. Two flexible conductors O lead current to the coil D from terminals P, which are placed across the mains, if necessary in series with a resistance, or connected to a separate source. A soft-iron keeper C is placed below the coil. When the current through the coil A has the normal direction, the movable frame rests against a stop H, and, when the current reverses, swings to the right and by a lever K lifts the latch J of the circuitbreaker. To make the cut-out operative both with maximum and reverse currents, the stop H is removed. By adjusting weights G along arms L, the apparatus can be set for various amounts of current. The weights G may be replaced by springs. The allowable maximum and reverse currents can be independently varied, as shown in fuller detail in Fig. 7, one of the levers K having pins R lying beneath the two weighted arms L pivoted to the supporting-spindle. Both weights normally rest on supports M, and one or the other must be lifted whichever way the swing takes place. A corresponding movement of the opposite cross-piece lifts the forked end J of the tripping- latch. The weights G are separately adjustable. To produce longer movements, the width of the movable coil or the length of the pole faces is increased, and the latter can be shaped so that the coil moves into an increasingly stronger field. The invention is also not restricted to the use of one coil and one air gap only. The keeper C may be pivoted at one end and linked to the tripping-latch. To make the value of the reverse current at which the apparatus will work independent of variations in the line voltage, without using an independent source of electricity, the magnet B is compoundwound, the series and shunt currents normally flowing in the same direction and therefore opposing when reversal takes place.
