Title: Improvements in lifting jacks
IPC: B66F3/08
Filed: 1937-03-18
Abstract: 491,324. Lifting-jacks; lifting ships' hatchway covers. TUTIN HATCHWAYS, Ltd., and BARRETT, H. R. March 18, 1937, No. 8045. [Class 78 (iii)] [Also in Group XXXIII] The lifting-pillar of a jack carries a loadengaging clamp operated automatically by the weight of the load. The load 48, Fig. 4, for example a projection on the hatchway cover of a ship, rests on the head of a spring plunger 42 so that it is partly embraced by the fixed jaw 44. A pair of movable jaws 46 pivoted at 60 so as to straddle the fixed jaw, are turned down from the dotted to the full-line position and then the jack is operated to raise the screwed member 26. Initially, the plunger is held down by the load and the spring 52 is compressed. During this period the wedgeshaped portion 62 of the casing engages the wedge-shaped ends of the jaws and is forced thereover to clamp the jaws round the load. A piston 68 limits the upward movement of the plunger 42 under the action of the spring. Fig. 7 shows a modification in which a pair of jaws 46 are pivoted intermediate their ends at 76 and are fitted with wedge-shaped portions 82 engaging the member 38. Three other modifications show jaws generally similar to those of Fig. 7 but mounted on separate pivots and in one case pivoted at their extreme ends without the tail-pieces 80 of Fig. 7. The body of the jack comprises a carriage mounted on wheels so as to travel along a rail as described in Specification 491,325.

Abstract: 313,657. Wildt, E., Holmes, H. H., and Wildt & Co., Ltd. March 16, 1928. Stockings and socks.- In forming stockings or other knitted fabrics wherein vertical stripes or other patterns are made by a number of independent thread guides, each of which supplies a thread to a separate needle, the striping threads are knitted into the fabric at each course by passing them either into the hooks or around the needles without entering the hooks. The striping threads thus appear either at the front of or at the back of the fabric without forming loose floating threads. The inside of a part of a stocking is shown in Fig. 1.

Abstract: 567,264. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., and DIXON, C. J. E. May 24, 1943, No. 8208. [Class 38 (v)] A neutral-point earthing resistor comprises a plurality of parallel-connected liquid resistance sections, one or more of which are permanently connected, whereas the others are disconnected by a circuit-breaker a predetermined time after a fault has occurred, so as to increase the resistance. The resistor may be constructed as in Fig. 2 of Specification 556,611, [Group XXXVI], and have more than two sets of two insulating bushings, all the terminal electrodes being earth-connected, whereas the intermediate electrodes are connected, one permanently and the others through a breaker, to the neutral point.

Abstract: 1462172 Riveting AVDEL Ltd 11 Jan 1974 [12 Jan 1973 20 Feb 1973] 1750/73 and 8238/73 Heading B3U The fastener placing tool described in Specification 1,272,771 is modified in that the torque limit sustained by a first torque-limiting rotary connection 30 between the first and second elements 15, 24 of the lead screw device is higher than that sustained by a second torque-limiting rotary connection 40 between the second element 24 and the tool body member 14 when the first element 15 is rotated in a direction to engage the mandrel 25, connected to the second element 24, with the fastener 11 and is lower when the first element 15 is rotated in the opposite direction to cause longitudinal movement of the mandrel 25. When a tube 17 carrying a nut 15 is rotated clockwise by a pneumatic motor, a drawbolt 24 carrying the mandrel 25 and a nosepiece 28 is rotated so as to screw the mandrel 25 into the fastener 11. Thereafter the nosepiece 28 is pushed back by the fastener head 13 causing dog teeth on the end of the nosepiece 28 to be urged with a greater force into engagement with teeth on the body member 14 thus preventing rotation of the nosepiece 28 and drawbolt 24. Upon further rotation of the tube 17, the friction connection 30, which may include the spring band 33, is overcome and the drawbolt 24 is moved rearwardly to place the fastener 11. When the tube 17 is rotated anticlockwise, the drawbolt 24 is moved forward and the nosepiece 28 is retracted from the fastener 11. Upon contact of the drawbolt head 31 with the nut 15, the clutch 40 slips and the drawbolt 24 is rotated anticlockwise to unscrew the mandrel 25 from the placed fastener 11.

Abstract: 1423225 Pneumatic brake systems SAABSCANIA AB 21 Feb 1973 [25 Feb 1972] 8520/73 Heading F2F A vehicle pneumatic brake system includes a driver operated brake valve 7 operable to supply compressed air from a container 3 to brake actuators 10, 12 via lines 8, 9 and double check valves 15, 16 respectively, and further comprises a line 17 extending from the pressure container 3 which line 17 incorporates a solenoid valve 19 actuable by the driver to control the flow through line 17 and hence the operation of actuators 10, 12 to give partial braking. The system is stated to be applicable to vehicles provided with automatic gear-boxes. As shown container 3 is supplied with compressed air by a compressor 1 via a line 2, and a pressure regulator 4 and the brake valve 7 are arranged in a parallel connection 5, 6. Actuators 10 brake the front wheels and actuators 12 brake the rear wheels, there being a quick-blow valve 11 in line 9. The line 17 which incorporates a pressure control valve 18, and a pressure reducing valve 20 as well as valve 19 leads to a relay valve 14 which in response to fluid flow through line 17 as controlled by solenoid valve 19 opens a branch line connection 13, 13a, 13b from the container 3 to double check valves 15, 16 and actuators 10, 12. The solenoid valve 19 is incorporated in a circuit 21 including a switch 22 closed when a cross-country gear is engaged and a switch 23 closed by a foot plate; closing of these switches 22, 23 causes energization of solenoid valve 19 and partial braking at a pressure reduced in branch lines 13a, 13b. The circuit 21 may incorporate an additional switch closed when the throttle is released.

Title: Transferring by hauling between elevated supports
IPC: B61B7/02
Filed: 1948-03-23
Abstract: 636,719. Transferring by hauling between elevated supports. COUPRY, L. A. G. March 23, 1948, Nos. 8548 and 8549. Convention dates, March 25, 1947 and Jan. 9, 1948. [Class 78 (iv)] A rope conveyer for transferring by hauling between elevated supports has compensating means to maintain the suspended load on a desired path, any variation in height operating to deflect the load suspended from a carrier running on a supporting rope is automatically compensated by the application of a simultaneous, opposed, essentially equal variation in height. The compensating means may be in the form of a drum T, and may act directly on one end of a supporting rope Cp or hoisting rope or may act indirectly through tackle or through a movable support. The drum may be driven by a separate motor or by the motor driving the drum of the hauling cable Ct. In Fig. 6, the drum t operating the hauling rope Ct is driven by a motor M, and controls the engagement of gears R1, 2 to cause winding in or paying out of the supporting rope Cp on the drum T. Alternatively two independent oppositely acting' drums may be used instead of the single drum T to effect compensation and the drums may be conical. Photo-electric means may be used for greater accuracy. Light from a source situated at one support is divided into two beams and strikes mirrors at the other support, the carrier on the correct path travels between the two beams any deviation causes interception of a beam and operates the compensating means. A single cell may be used by adding a shutter with rapid interception and alternations of light beams and simultaneously switching the relay for the direction appropriate for correct compensation. The photo-electric means may be used to supplement the usual compensation by the drum t. The drums T and t are linked together and are mounted on a common shaft. The hauling or supporting rope is connected with the drum T by an endless rope having turns on the drum and carrying a sheave for the other rope. The drum has a helical groove for the rope and by a suitably shaped drum any path may be obtained. The drum may have a series of cylindrical sections and may have identical compensation for the carrying, hauling or the hoisting rope. To reduce the pull of the rope Cp on the drum T a tackle. may be interposed between the sheave and the supporting rope Cp by which means the rope can be passed over the top of the supporting tower or the rope may be interrupted and continued by a flexible rope or flat link chain.
