Title: Magnetic particle coupling for obtaining linear movement
IPC: F16H49/00
Filed: 1955-11-03
Abstract: 791, 383. Electrically-actuated valves. FOXBORO CO. Nov. 3, 1955 [Nov. 24, 1954], No. 31504/55. Class 135. [Also in Groups XXIV and XXXV] In an electromagnetic coupling for obtaining linear movement in either direction of a housing which may operate a valve, the housing contains a body of loose magnetic particles surrounding a driving member such as a moving ribbon or a rotating screw so that on the application of a magnetic field the particles are solidified to couple the housing to the driving member. As shown in Fig. 1, magnetic particles 12 in a housing 11 surround a motor-driven shaft 10 having threads 101, 10<SP>11</SP> of opposite hand. On the energization of one or other magnetic coil 13 or 14 the particles 12 are solidified to form a "nut" adjacent the appropriate thread 10<SP>11</SP> or 10<SP>1</SP> and'the housing is axially moved in one or other direction, according to which coil is energized. The particles 12 may be in suspension in oil to form a magnetic fluid mixture. The housing 11 is held against rotation by a tongue 29 engaging a slot 30 and is guided on the shaft 10 by bearing and sealing washers. The housing may actuate a valve 18, the coils 13, 14 being controlled by changes in temperature or flow. Alternatively the housing 11 may be linked to a pen co-operating with a rotating chart. In a modification the housing is built up by two telescopic sleeves joined together, and an external feedback pipe connects opposite ends of the chamber containing the magnetic fluid to avoid pressurizing it. In a further modification a structure 67, Fig. V, slidable on guide bars 65 carries two magnetic coils each having pole pieces depending into a rectangular tank 64 containing magnetic fluid surrounding two oppositely-rotating intergeared threaded shafts 70, 71, each having a single right-hand thread. Each pole piece partially embraces a respective screw and on energization of one or other of the two coils the fluid forms a " nut " around the appropriate screw so that the structure 67 is linearly displaced. In an alternative form of coupling a housing 83, Fig. VII, has upper and lower coils surrounding chambers containing magnetic fluid through which pass the oppositely-moving upper and lower stretches of a ribbon 79 supported by pulleys 77, 78. Energization of one or other of the coils causes the housing 83 to be locked to the upper or lower stretch of the ribbon for movement therewith to right or left. Reference has been directed by the Comptroller to Specification 649,553, [Group XXIV].

In a rug-making machine, one or more hooks or needles bearing pile-forming material is/are moved at right angles to a pair of angle bars holding base material therebetween, one of the bars being movable towards and away from the other fixed bar. As shown, base fabric 13 is damped between a fixed angle bar 10 and a movable single bar 11, and passes over the upper straight edge of angle bar 10 with two adjacent rows of aligned apertures extending above the edge. A carriage 21, has a downwardly-extending rib 22 slidable between two fixed angle bars 15,18 parallel to bars 10,11. A plate 24, slidable on carriage 22 at right angles to bars 10,11, carries needles 30 having prongs 31 with inturned ends. A cut length 39 of yarn is placed around each needle and plate 24 to moved towards bars 10,11 by a handle 35 to pass the needle ends through the aligned apertures. The free ends of each length are then carried over the folded edges 12 of the fabric and are passed between the prongs 31 and the plate 24 is withdrawn, whereby the lengths are knotted to the folded edge. In a modification, Fig. 8 not shown, each needle is slidably supported in a fixed guide 44 and has an upstanding pin 45 engaged in an inclined cam slot 47 provided in a cam box 46, slidably mounted for movement transverse to the needles. Movement of box 46 which may be effected either manually or mechanically, in one direction serves to project the needles in succession through the fabric, and in the other direction to withdraw the needles in succession.

Filed: 1952-12-22
Abstract: 734,534. Skew gearing. STANDARD MOTOR CO., Ltd. Nov. 24, 1953 [Dec. 22, 1952], No. 32398/52. Class 80 (1). [Also in Group XXIX] A single control for imparting to a member a movement which is sometimes axial and sometimes rotary, or possibly a combination of both, is shown applied to a valve for the torqueconverter disclosed in Specification 734,533, and comprises a control arm 22 connected to the movable valve member 12 by a skew gear pair 24, 25, a rotatable pin 11 engaging a cam slot in the member to determine the extents of the axial and rotary movements. The cam slot shown has two circumferential portions connected by an axial portion so that as the arm 22 on the gear 24 is turned and applies to the skew teeth of the gear 25 a force having both axial and circumferential components, the member 12 is caused to move first angularly, then axially, and finally angularly again. The axial portion of the cam slot could be replaced by an inclined portion. The pin 11 has sufficient clearance to allow rolling in the slot and has also axial clearance in the boss 15. The inlet 27 of the valve communicates with a waisted portion 29 of the member 12 which is connected to a bore 31. The latter has three axially- and angularlyspaced ports, one of which is shown at 32, feeding fluid to three supply points 34, 35, 36 for various parts of the torque converter, the points being selected by the angular movements of the member 12 in either of its two axial positions. In the lower position, turning of the member 12 feeds fluid at a predetermined pressure to the supply point 34; in the raised position, turning of the member 12 feeds fluid at a higher pressure to either of supply points 35 or 36. Those points which at any time are not being fed with fluid are exhausted through waisted portions and restricted openings 40. In order to effect a change in the fluid pressure in bore 31 as the member 12 is raised, the inlet 27, which is supplied with fluid at a high pressure, communicates with a passage 45 adjacent a relief valve 47, shown partly open against a spring 48 which thus controls the pressure in the bore 31, the excess flow being supplied along a line 49 to the bearings and clutch of the prior Specification. The spring reacts on a washer on the end of the member 12. An additional spring 52 is provided and as shown is idle, but when the member 12 is axially raised by the control 22 the spring 52 reinforces the spring 48 and so increases the pressure supplied to the bore 31. A spring-pressed ball 55 diverts excess pressure to exhaust 58. The fluid pressure may be supplied by a gear pump.
