Inventor: SPUEHL JULIUS
IPC: B21F33/04
Filed: 1955-02-22
Abstract: 765,149. Coiling. SPUEHL AKT.-GES. Feb. 22, 1955, No. 5245/55. Class 83 (4). Apparatus for forming eyelets at the ends of helical connectors connecting parallel rows of upholstery coil springs comprises a finger pivoted on a member movable parallel to the axis of the connector so that the finger, which engages opposed parts of the end convolution, rocks about its pivot to bend back the convolution to form an eyelet. Connecting wire 2 is fed by means 3 through a coiling device 4 in which a fixed curved groove forms the wire into a helix 5 which screws itself round end coils of adjacent helical coil springs 1 to connect them together. When the leading end of the helix 5 reaches the end position an eyelet is formed therein by a device 7. The device 7 comprises, Fig. 3, a finger 8, extending in the plane of and obliquely to the axis of the helix 5, pivotably mounted on a transverse bolt 9 carried by a support 10 on a piston rod 11 operated by compressed air or other means to move parallel to the helix axis. In operation, when the helix 5 reaches a stop 25 on a pivoted arm 24 it rocks the arm to close a switch 22 to stop the wire feed and light a signal lamp, the finger 8 at this position entering, and engaging opposite parts of, the end convolution of the helix. The support 10 is then moved forward so that the finger 8 rocks about the bolt 9, against a spring 18 to bend the convolution over to form an eyelet, Fig. 5.

IPC: H01F7/14
Filed: 1927-02-24
Abstract: 291,494. Wright, A. Feb. 24, 1927. Electromagnets. - An electromagnetically operated device which may be utilized for controlling switch contacts, valves &c. comprise a field magnet, an armature, a commutator mounted on the armature spindle and means for closing a circuit through one or other of the commutator brushes and segments and one or other parts of the armature and field winding characterized by the coil on the armature being tapped at a point between its extreme ends, such tapping being connected to one end of the field magnet winding. As shown in Fig. 1 a tapping 15 between the ends of a winding carried by an angularly movable H-armature 2 is connected to one end of a winding 13, 14 carried by the field structure 1. A commutator with segments 5, 6 is mounted on the armature spindle, brushes 10, 11 bearing on the commutator in such a manner that only one brush is in contact with a segment at a time. When. a circuit to one of the brushes 10 as shown is completed by a control switch such as a thermally operated member engaging the right-hand of its fixed contacts 8, 9, current flows through one portion of the armature in series with the field coil so that the armature is moved through an angle of approximately 90‹. A similar return movement takes place when the control switch is moved to its other contact completing a circuit through the other section of the armature winding. The starting torque may be increased by providing a central polar projection. as at 17 and the torque in opposite directions mav be varied by providing the two armature winding sections with different numbers of turns or values of resistance. In a modified arrangement of armature shown in Fig. 2 the armature winding 12 is wound on the central limb 17 of a three-limbed core 2 and the effective air ga.p is variad throughout the stroke by a displaced axial mounting of the armature. The movement of the armature may operate switch contacts in any suitable manner or may be used for the control of a valve. As alternative the armature may be fixed and provided with a continuous winding the field coil magnet carrying a tapped coil being movable.

Abstract: 162,457. Mensforth, H., Cowell, F. A., and Metropolitan-Vickers Electrical Co., Ltd. Feb. 21, 1920. Surface and outline gauges. -A device for gauging the accuracy of the teeth of a gear - cutting hob comprises two parallel spindles mounted in V-blocks carried on a baseplate, one of which carries the hob under test, while the other is axially movable and carries a feeler and dial indicator, this spindle being positioned longitudinally by a series of distance-pieces inserted between the end of ,the spindle and a fixed stop. The spindle 1 carrying the hob 2 is mounted in V-blocks 7 slidable transversely in grooves 8 in a base-plate 9'. The spindle 3 rests in V-blocks secured to the base-plate, and carries a rest 23 which may be clamped to the spindle 3 by screws and clamping parts. The plate 23 is fitted with a handle 29 by which the plate 23 and spindle 3 may be rocked. The plate carries a twoarmed lever pivoted at 31 the short arm of which is adapted to engage the hob teeth, while the long arm abuts against the plunger of a dial gauge 34. The spindle 1 is fitted at the end with a hardened surface 13a abutting against a hardened surface 13 carried by a stop 12 which may be adjusted slightly in a transverse direction. The end of spindle 2 is also fitted with a hardened piece 3<a> between which and the anvil of a micrometer screw 42 distance pieces 5 of known length are placed, these pieces resting in V-blocks 36. Two sets of distance pieces are used; one set termed " length " gauges determines the position of the shaft 3 for each tooth in a longitudinal row, while the other set termed " lead "gauges determines the position of the shaft 3 with respect to the lead of the teeth between one row and another. The lever 30 is kept horizontal by a stop under the pivot 31 engaging an horizontal bar 45. The position of the cutting face of each tooth is determined by engagement with a block 47 sliding on the bar 45. In use the particular length gauge for a particular tooth is placed in position, and the feeler placed to engage the tooth at the pitch line. The screw 42 is then operated so that the dial gauge reads zero. The appropriate length gauges for the various teeth in a row are successively used and errors noted. This is repeated for the next row, the suitable lead gauge being used and so on. The gauging may take place in a spiral direction when a length gauge is kept in and the lead gauges changed. The teeth of hobs with spiral fluting may be measured still, as it were, in longitudinal rows, but each tooth is brought into contact with the block 47 and the rotary movement of the hob necessary to place each tooth on the block is allowed for in the length gauge or means may be provided to advancethe spindle 3 the required amount.

Filed: 1922-02-24
Abstract: 198,058. Invernairn, (W. Beardmore), Lord, and Chorlton, A. E. L. Feb. 24, 1922. Automatic speed control.-In a road or rail vehicle propelled by an internal-combustion engine with variable speed transmission, the road speed is controlled by varying the transmission by means of mechanism controlled differentially by the road speed and by the speed of a shaft driven by the engine or a separate source of power. The variable speed transmission may be mechanical, such as an epicyclic gear, or electric or hydraulic, and may be arranged to give a variable ratio from zero to direct drive, with overspeeds, and the control is applicable to a locomotive such as is described in Specification 178,935, [Class 79 (i), Locomotives &c.]. The road or rail wheels L, L' drive bevel wheels K, K<1> provided with clutches so that one of the wheels, dependent on the direction of motion, drives a bevel wheel J which carries two shafts H, H<1> with wheels G, G<1> gearing with wheels C, D. The wheel D is mounted on a shaft E co-axial with and driven from the engine shaft, while the wheel C is mounted on a shaft B carrying a governor A. This governor actuates a floating lever M coupled by a rod R to a control valve S or other actuating-member of the variable speed transmission. For hand control, as at starting, a lever Q controls a valve supplying fluid to a cylinder O, the piston N of which varies the position of the pivot of the lever M and so operates the valve S independently of the governor. The lever Q also regulates the supply of fuel to the engine. After the lever J has been moved to fullload position and the transmission is on direct drive, the governor acts to increase the speed of the engine itself, such as by means of a subsidiary valve controlling the fuel supply to the engine. The governor then varies the transmission so as to provide overspeeds.

Abstract: 306,491. Poege, M., and Poege, F., (trading as Gentsch, H., [Firm of]). June 16, 1928, [Convention date]. [The subject-matter of this Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 22, 1929]. Healds, threading. -In apparatus for separating and cutting off the outside thread of a warp, and preventing threads from clinging together during further treatment, e.g. when being drawn into a loom, a number of oscillating separating members are provided operating in sequence. In one form the feeding machine is moved intermittently across the warp threads 12, which are held vertically by clamps 1, by pawl and ratchet gearing 20 actuated by an electromagnet 15; in operation the outside thread is engaged by a hook 2 carried by and actuated synchronously with the feeding machine, and is placed by the hook upon a stop 13 which is moved thereby to close a circuit to actuate the first separating member 3; actuation of the member 3 closes a circuit including the second separating member 4 which in similar manner actuates a third member 5. The separating members are V-shaped to ensure separation of the outside thread from the adjacent thread. The separated thread is guided by the member 5 to a rotary cutter 6 which is vertically adjustable and is actuated by the member 5. Trapping members 10, 11 are arranged to receive the portions of the thread engaged by the members 3, 4, and the trapping member 10 co-operates with a switch so that the circuit including the magnet 15 cannot be closed for moving the machine until the separated thread is manually removed from the trapper. In a modification the electrical controlling means are replaced by mechanical apparatus and the separating members 3 - - 5 are actuated in sequence by angularly displaced cams arranged on a vertical shaft 33. The machine is moved across the threads by ratchet gearing 20, Fig. 12, actuated by a lever 23 which normally is operated as one with a second lever 24 by means of a crank and connecting rod 22 from a motor. On engagement of the hook 2 with a thread 27 the lever 23 is held against movement by a rod 25; the lever 24 now pivots about a point 28 on the lever 23 until the end of the lever 24 is engaged by a catch 26, moving by its other end a rack 30 which rotates a pinion on the shaft 33. A verticaiiy adjustable cutter and trapping means are provided in this form, and means for locking the hook 2 in inoperative position are actuated by the trapper associated with the first separating member.

Abstract: 1378428 Traverse mechanism SPINNER OSAKEYHTIO 8 Feb 1972 [10 Dec 1971] 5708/72 Heading D1J In a device for winding a thread on a spool, the stroke length of a reciprocating guide is reduced as the spool diameter increases, and is also cyclically varied, and the speed of the guide is changed with changes in the stroke length. As shown, Fig. 1, spool 2 is rotated by friction roll 3 rotated at constant speed. Thread guide 4, Fig. 2, is reciprocated by grooved roller 5 via link 18. End 20 of link 18 engages rod 19 which may be pivoted to alter the stroke length of guide 4. The increase in diameter of spool 2 pivots lever 22 to pivot lever 19 via follower 23, roller 24, and rod 25 to alter the stroke length of guide 4. Cam 27, rotating at constant speed, continuously pivots lever 14 via lever 25 to cyclically alter the stroke length. Roller 5 is driven from friction roll 3 by friction roll 10, spindle 9 and friction roll 11 mounted on pivoted member 29. The pivoting of rod 19 pivots member 29 via link 15 to alter the speed of roller 5 and, thereby, the speed of guide 4. The degree of movement of member 29 may be controlled by adjusting the position of roll 14 which bears on link 15. In this manner the product of stroke length and stroke frequency may be varied as desired, e.g., may be kept constant. For Figures see next column

Abstract: 333,404. Drysdale, H. Feb. 21, 1929. Disc and like mills.-In a grinding mill of the type comprising convex and concave stones or elements which rotate about inclined axes which are, preferably, adjustable, such as is described in Specification 206,924, means are provided for imparting a positive drive to both grinding elements. The stones may be water-cooled and may be moved laterally for cleaning. The stone 12 is supported by a sleeve 45, Fig. 4, mounted in bearings 46 housed in a hollow casing 14 pivoted at 28, Fig. 1, to a balanced slide 15 movable on guides 17 by a screw 18 operated by a hand-wheel 20. The lower stone 13 is mounted on an inclined spindle 58 supported in bearings 59 and is guided by flanges 65, 66. The stone 13 is driven from a motor 11 by pinions 29, 30, shaft 31 and bevel wheels 32, 33. The upper stone may be driven separately, but as shown, is driven from the shaft 31 by bevel wheels 35, 36, shaft 37 and a train of wheels 38 - - 44 of which the latter is secured to the spindle 45. The wheel 42 is removable, and the wheel 43 is mounted on an arm 101 rotatable about the axis of the stone 12 so that the speed ratio of the upper stone may be varied by changing the wheels. The upper stone 12 is adapted to be moved towards or away from the stone 13 by means of a bell-crank lever 88 pivoted to the casing 14 at 89. The pivot 86 at the end of one arm passes through an elongated slot 87 in the casing 14 and engages the outer shell of the bearings 46 which is slidable in the casing. The other end of the bell-crank engages a spring 96, the abutment 94 of which is secured to a rod 92 slidable in lugs 90, 91 by a hand-wheel 93. The stone 12 can thus move automatically away from the stone 13 to clear any obstruction. Coal &c. may be fed to the mill by a hopper 81 which communicates with the hollow spindle 45 of the upper stone and is thence led to grooves 80 in the stone 12. The feed may be facilitated by an adjustable rod 82 or by a stationary feed-screw. A scraper of the kind described in Specification 206,924 may be used to remove material from the stones. The Provisional Specification states that a revolving brush may be used to remove the ground material from the lower stone so that it can be drawn off by a fan. The stone 12 is fixed in a casing 51 by means of an iron block 54 and a cement 53 which may be sulphur. The stone 13 is fixed by an iron block 68 and is cemented into a casing 63, the casing 63 together with a supporting flange 62 forming an enclosed space 72 for the circulation of a heating or cooling medium which enters through the hollow spindle 58 and returns through a tube 73 in the spindle. The bearings 59 are protected from dust &c. by a depending flange 99, Fig. 5, on the rotatable casing 62 which dips into a trough of liquid 98 formed in the fixed casing. The fixed casings 48, 61 enclosing the stones have their abutting edges machined or a packing ring may be interposed between them to prevent access of air.
