Abstract: 1497908 Bending; making rail clips; forging PANDROL Ltd 29 April 1976 [7 May 1975] 19251/75 Headings B3A B3E and B3H The end 5 of a permanent-way rail clip made by bending metal rod at least 8 mm. thick to the configuration illustrated in Figs. 1 and 3, is upturned in a bending operation in which a first shaping tool forces the whole of that part which is to be upturned into contact with a second shaping tool. In the method described, the rod is first bent to the shape shown in Fig. 7, i.e. with straight limbs, by repeated bending in two different planes on a threepoint bender. Limb 1 of the clip is then placed in groove 40 of a lower tool assembly, and slid into socket 41 until part 4 abuts stop 44. The reverse bend 2 then lies in groove 45, see also Fig. 8, with limb 3 overlying block 47, and limb 5 overlying recess 61 in tool 60, Fig. 9. A composite upper tool, Fig. 12, is then forced down by a crank drive, so that tool 82 bends limb 3 down in three-point fashion, and forms a flat 3A on the limb by contact with block 47. Tool 81 holds limb 1, and tool 80 forces the end 5 of the clip into recess 61 to form the required upturned end. The tool 60 and/or block 47 are adjustable in height as in Fig. 9, where the tool is located by screw 62 holding the tool on to a wedge 68 having projections 69 slidable in recess 70 in block 63, so that the tool may be unscrewed, the wedge moved to left or right, and the tool screwed up again.

Title: Thread replenishing mechanism for lock stitch sewing machines
IPC: D05B59/00
Filed: 1964-05-11
Abstract: 994, 569. Sewing machines. SINGER CO. May 11,1964 [May 14, 1963], No. 19503/64. Heading D1G. In a lockstitch sewing machine in which a bobbin, journalled in a rotary looptaker, is adapted to be rotated, for being wound in situ, by a member movable into and out of engagement with the bobbin, said member is connected to a lever which is spring-biased for moving said member to the disengaged position and is connected to a push rod protruding through an aperture in the machine casing and being biased by spring means against the side of said aperture, the push rod being provided with latch means adapted, on depression of the push rod, to engage releasably with the machine casing. A rotary looptaker body 40, carried by a hollow shaft 25 and driven by gears 22 from a bed shaft 24, journals a bobbin 42 adapted to be rotated by a member 43 in order to be wound in situ. Member 43 is rigid with a shaft 44 which is journalled in shaft 25 and carries at its lower end a pin 47. If shaft 44 is shifted upwardly, pin 47 enters a recess 48 in the gear 22 rigid with shaft 25, and pin 49 on member 43 enters a recess in body 40. A lever 60, pivoted intermediately at 61, carries at one end a leaf spring 62 embracing the lower end of shaft 44 between collars 46 and 64 thereon. A spring75 biases lever 60 counter-clockwise to engage the cushioned upper end 77 of a pin 76 on lever 60 with the machine bed 11, and to shift shaft 44 to its lowermost and inoperative position. The other end of lever 60 is connected by a leaf spring 66 to the lower end of a rod 65 which projects upwardly through a bush 69 in bed 11, and which is biased against bush 69 by spring 66. The junction between rod 65 and a push button 68 at the upper end thereof is constituted by a shoulder 70. If the presser bar 14 is raised to lift the presser foot 81, and downward pressure is applied to push button 68, shoulder 70 is engaged with the under surface 71 of bush 69 to lock rod 65 in the depressed position and shaft 44 in the raised and bobbin-driving position. Lateral pressure then applied to button 68 serves to release rod 65 and thereby to return shaft 44 to the inoperative position. A lever 85 co-operates with a block 83 rigid with presser bar 14 to raise the latter. A cable 90 is attached at one end by a screw 91 to block 83. The other end of cable 90, after passing through a fixed guide 92, is attached to one arm 93 of a lever 94 pivoted intermediately at 95 to the machine frame. The arrangement is such that when lever 85 is actuated to raise the presser bar, the needle thread tension is released, and the end 96 of the other arm of lever 94 is moved clear of rod 65. If the presser bar is lowered while the bobbin is being driven, end 96 engages bar 65 transversely to release shoulder 70 from surface 71. End 96 then enters a notch 100 in rod 65 to prevent depression of the latter when the presser bar is lowered. Driving. A motor 26, mounted in the machine standard 12, drives the arm shaft 17 via a worm 27 and worm wheel 28.

IPC: F22D5/18
Filed: 1957-06-21
Abstract: 836,146. Feedwater supply systems for steam boilers. WEIR Ltd., G. & J. June 20, 1958 [June 21, 1957], No. 19562/57. Class 123(2) A feedwater supply system for a boiler 12 comprises low pressure pumps 1, 2 dischanging through non-return valves 3, 4 to a high pressure pump 5 or to a line 6 by-passing the pump 5 and containing a non-return valve 7, the high pressure pump discharging into the boiler through a feed line 8 containing a non-return valve 9 and an excess pressure valve 10 which throttles the discharge of the pump 5 to prevent excessive pressure drop across a level-controlled regulator valve 11 in the line 8. The line 6 is connected into the line 8 between the valves 10 and 11. In operation at low boiler loads when the boiler pressure is high the valve 7 is closed and the discharge from the pumps 1, 2 is boosted to the high pressure required in the pump 5. As the load increases the boiler pressure falls and the pressure in the feed line 8 falls until it reaches a value equal to the discharge pressure of the low pressure pumps 1, 2. On a further increase in load resulting in a further decrease of feed line pressure the valve 7 opens and water flows directly from the pumps 1, 2 to the boiler.

Title: Improvements in brake construction
IPC: F16D55/46
Filed: 1943-11-24
Abstract: 574,697. Disc brakes. LAMBERT BRAKE CORPORATION. Nov. 24, 1943, No. 19642. Convention date, April 15. [Class 103 (i)] A disc brake, particularly for vehicles, wherein the friction discs and the actuating means are completely enclosed, comprises a casing divided into two chambers in which the discs and a fluid-pressure operated diaphragm are respectively arranged, whereby the diaphragm is isolated from the heat produced by braking. Self-energizing means for augmenting the braking pressure are provided. As shown, a casing 10 bolted at 5 to a flange 4 on the housing of a vehicle wheel axle has detachable cover-plates 9, 13 and a web 12b forming annular chambers 19, 14, in one of which a diaphragm 21 is mounted and into the other of which extends a rotatable disc 6 axially slidable on pins 7 secured to a flange 3 on the wheel hub 2. The flange 3 completes the closure of the casing to prevent entry of water &c. A disc 15 is rotatable to a limited extent on an annular projection 15b of the casing. Rollers 17 bear on cam discs 16 arranged in circular recesses formed in the disc 15 and the casing. Pressure applied to the outer side of the diaphragm 21 by pressure fluid admitted by the connection 23, is transmitted to the disc 15 by a ring 20 and rods 25, thus gripping the rotating disc 6 between the disc 15 and the cover-plate 9. The tendency of the disc 15 to turn with the disc 6 causes the rollers to climb up the cam face of the discs 16, thus increasing the pressure on the discs. Disengagement of the discs is effected by springs 27. The diaphragm 21 is of greater effective area than that of the friction members and it may comprise alternate layers of asbestos fibre composition and rubber.

Title: Improvements in devices for photographically copying sound films
IPC: G11B7/00
Filed: 1937-07-17
Abstract: 489,809. Copying photographic soundrecord films. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. July 17, 1937, No. 19854. Convention date, July 20, 1936. [Class 98 (ii)] In apparatus wherein the negative and sensitive films are driven without slipping each by a separate smooth roller, one at and the other near the copying zone, one roller is directly driven, without a slipping coupling, by a motor running at constant speed, and the second roller is driven through a non-slipping friction coupling having a variable transmission ratio either by the same motor or by another motor running at constant speed in synchronism with the first motor. The arrangement is useful when a copy of different dimensions is required, or when compensation is desired for the difference in perforation gauge of the films due to shrinkage of the negative during processing. The Figure shows a construction for the latter purpose. The sensitive film 1 is drawn from a roll 3 by a roller 2 fixed on a shaft 27. The negative film 5 is drawn from a roll 8 by a roller 7 fixed on a parallel shaft 26, and passes over the roller 2 where copying occurs at the zone A. From the rollers 2, 7 the films pass over sprockets 4, 11, driven by the films, to their respective take-up rolls. Tensioning rolls guide the films at various points. Shaft 26 is driven by an electric motor, and carries a fixed roller 29 and a loose roller 28 opposite respectively to a loose roller 31 and a fixed roller 35 on shaft 27. Rollers 29, 31 are connected by a laterallysupported ball 30, and rollers 28, 35 by a ball 36 adjustable by anarm 25 which is displacedin the direction of its length by differential gearing D when the shafts 14, 16 of the sprockets 11, 4 run at different speeds due to the aforementioned film shrinkage. A rotary disc 32 is spring-pressed upon the balls 30, 36, and the arm 25 is directed along a radius of the disc. Thus, the fixed roller 29 drives the disc 32 through the ball 30, and the disc 32 in turn drives the fixed roller 35 through the ball 36, so that rotation is communicated from shaft 26 to shaft 27, which turns at a speed depending on the radial position of the ball 36 on the disc 32. A modification is described in which shaft 26 is driven by one motor, and shaft 27 is driven through a ball coupling similar to the above from the shaft of another motor running in synchronism with the first motor.
