Abstract: 716,319. Time switches. MIDGLEY, A. H. May 29, 1952 [June 19, 1951], No. 14487/51. Class 38(5)  A time-delay mechanism for a switch comprises a cam 3 mounted on a brass cup 2 and having a pin 4 movable in a slot 1a in a fixed plate 1b. The pin 4 is connected by a spring 10 to a pin 7a in a member 7 mounted on a shaft 6 also carrying an operating arm 8 connected to switch contacts. One arm of a bell-crank lever 12 pivoted at 11 engages the cam, the other arm having a pin 15 in an inclined slot 14b in a member 14 having a slot 14a engaging pivot 11. Member 14 is urged upwards and to the left by a spring 17 and has a latch portion 14c co-operable with a lug 9 on member 7. When arm 8 is moved counter-clockwise, the cam 3 is rotated in the same direction by the engagement of lug 9 with a step 3a on the cam until pin 4 engages the end of slot 1a as shown. This pin is connected to a gear train 19, 27 including a ratchet-and-pawl drive which slips during this movement. Reverse movement of arm 8 rotates the lug 9 clockwise until it is latched beneath portion 14c, thus straining spring 10. The cam 3 is prevented from rotation until a brake 28 operable by a plunger 31 is released, the gear train then 'allowing the cam to turn slowly clockwise. When lever 12 drops down step 3b on the cam, the member 14 is tilted clockwise to release lug 9 and member 7 which are rapidly returned clockwise by spring 10 to rotate the arm 8 and actuate the switch.

Title: Improvements in or relating to engraving machines
IPC: B44B3/00
Filed: 1930-05-12
Abstract: 354,764. Engraving-machines. COOKE, TROUGHTON, & SIMMS, Ltd. and LINN, J. D., Buckingham Works, York. May 12, 1930, No. 14590. [Class 100 (ii).] In an engraving-machine of the type in which a controlling member is guided in a desired path and operates a cutting tool by means of a pantograph or like linkage, the motion of the controlling member is determined in one direction by a rotary copy cam device and in a direction at, and in a plane at, right-angles thereto by a groove or its equivalent in or on the cam surface, the path of each groove lying to one side or other of a mean line. The mechanism enables a series of engraving operations to be performed. A rotating tool 1 is carried by a boss 6 on a pivoted frame 3 and is held up to its work by a pivoted lever 10 one end of which rests on a cam 22 rotated in synchronism with the work-holding table 7 whereby the tool is allowed to move away from the work-table during a portion of the rotation thereof. Coupled to the pivoted frame is a pantograph lever system the pointer 4 of which is adapted to traverse a cam member 5 rotationally and slidably mounted on a shaft 12 ; the pointer by reason of the cam form moves to and fro radially with respect to the shaft 12 and by reason of the grooves 16 oscillates about a mean position parallel to the shaft 12. The drive for the cam member is by means of pinion 15 in engagement with a long pinion 14 on a shaft 13 which is geared to the main shaft 20 from which is also taken the drive 25 .. 28 for the work-table 7. The engraving of each character is accomplished during a single revolution of the copy cam but the actual engraving operation takes place during only three-quarters of such revolution, the tool being lifted during the idle quarter revolution. During the idle portion the transfer of the completed work-piece and introduction of the next work-piece of the series is effected. In a modification the copy cam may be made up of a series of individual cams placed side by side. The shaft has an extension on which is carried a non-rotating collar 50 which according to its longitudinal position will engage with one or other of a series of pegs 49 fitted into holes 48 on a cylinder which is adapted to be rotated in steps by gearing 34 from the copy cam shaft. By suitable disposition of these pegs the sequence in which the individual cams are used may be selected.

Title: Improvements in or relating to ingot casting machines
IPC: B22D7/04
Filed: 1932-05-24
Abstract: 402,097. Casting-machines. JONES, E. F., and MAUSS, W., Victoria Station House Victoria Street, London. May 24, 1932, No. 14729. [Class 83 (i).] Casting-machines.-An ingot casting - machine comprises a series of moulds pivotally mounted on a conveyer and carried step by step to successive stations, the moulds being tilted to horizontal position after charging to permit an ejector to enter the bottom of the mould and eject the casting, the mould then being returned to the vertical. Moulds 2 are carried on an annular table 7 which is rotated step by step by arms 17, 18 of a bell crank lever carried by a shaft 19. On clockwise rotation of the shaft by a hydraulic piston 20 through a rack 21 and quadrant 22, a pawl 23 on the arm 17 engages a notch 10 on the table partially to rotate it, a spring buffer 25 on the arm 18 engaging a stop 11 towards the end of the movement. At the station a molten metal is introduced into the mould through a stationary spout 12, at the station b the ingot is acted on by a plunger 13 as described in Specification 402,096 to bring it to hollow form, at station d the mould is tilted to horizontal position, at station e the ingot is ejected, and at station h the mould is restored to vertical position. A roller path 16 supports the moulds in the horizontal position. A timing mechanism 53 such as that described in Specification 402,096 controls the operation of the various parts of the apparatus. Casting processes.-Cooling air is supplied to the interior of the hollow ingot through nozzles 51. Moulds; coating and lining moulds.-A mould 2 is mounted on a pivot 3 on the table 7, apparatus for raising or lowering it between vertical and horizontal positions at each of the stations d, h, comprising a piston 33 rocking a shaft 26 through a rack and pinion 34, 35 thus oscillating a lever 27 through the linkwork shown substantially about the pivot 3, the lever 27 being in contact with the mould. Catches 36 secure the mould to the lever 27, but are released under the action of counterweights 37 at the end of the movement. The counterweight at station h acts through gears 40. Cooling air is supplied to the moulds through nozzles 52, which may also supply graphite for reconditioning. Castings, extracting.-The casting and the conical plug 15, are ejected by a rod 44 passing through a hole in the base of the mould, the rod and a plunger 46 of large diameter being first advanced together by the fluid pressure to free the casting, and the rod 44 then continuing to advance alone to complete the ejection.

Title: Flashing or twinkling electric incandescent lamp
IPC: H01H43/30
Filed: 1955-05-23
Abstract: 797,892. Flashing electric lamps. LUMALAMPAN AKTIEBOLAG. May 23, 1955 [June 12, 1954], No. 14826/55. Class 39(2) A flashing lamp in which a length of filament is short-circuited periodically by a bimetal strip is characterized by the filament being supported at its ends and at one or more intermediate points, the bimetal strip being fixed adjacent to and in electrical contact with one point of support and arranged to make electrical contact with another point of support when affected by the heat from the length of filament with which the strip is associated. In one arrangement a filament 5, 6 of inverted V-shape has its apex supported by a resilient wire 9 which has its lower end sealed within a glass bead 7, the two ends of the filament being connected to leading in wires 3, 4 also sealed within the bead 7. A single bimetal strip 10 fixed to the upper end of the wire 9 extends downwardly so that in its inoperative position it bisects the angle between the parts 5, 6 of the filament. When, however, the filament is energized, the bimetal strip is heated and warps, e.g. to the left, where it contacts the inturned end of the leading-in wire 3 and short-circuits the left-hand limb of the filament. In a modification, Figs. 2a and 2b (not shown) two bimetal strips extend downwardly between the limbs of an inverted V-shaped filament from a common support and by making the limbs of different lengths, three different degrees of brightness may be obtained when either or both filaments is, or are, energized. In a further modification, Fig. 3b, a substantially straight filament 6 stretched longitudinally with its ends connected between two leading-in wires 3, 4, is provided with an intermediate support comprising a wire 13 which is supported by the glass bead 7 holding the leading-in wires in position and has its upper portion offset and secured to the filament, the offset end 13a forming a contact for the lower-end of a bimetal strip 14 extending downwardly from an upper connecting point with the offset upper end of the longitudinal leading-in wire 3. The position of the point of connection between the offset portion of the intermediate supporting wire 13 and the filament may be varied so that different lower lengths 6 are obtained. Specification 694,660 is referred to.

Title: Improvements in and relating to control mechanism for internal combustion engines
IPC: F01L9/10
Filed: 1939-05-19
Abstract: 529,012. Fluid pressure-servomotor-control systems. DUNCAN, H. L. May 19, 1939, No. 14985. [Class 135] The timing adjustment of the admission valve of an internal combustion engine is dependent on fluid pressure set up by an engine driven pump modified by the varying pressures in the induction pipe. The crank-shaft a or the cam shaft b is formed with an extension 10 surrounded by a bush 17 having internal and external straight and inclined splines associated with corresponding grooves in the extension 10 and one of the gear-wheels 19, 20. Axial movement is imparted to the bush 17, with consequent relative angular movements of the gears 19, 20, by fluid pressure on a piston 18 integral with the bush. A pump 22 in the crankcase and driven from the crank-shaft circulates oil by way of a pipe 29 to the chamber behind the piston and thence back to the crank-case by openings 30 and passages in a brake disc 31. The rate of circulation is controlled (1) by the shape of the openings 30 and the degree to which they are uncovered by the piston 18, (2) by a needle valve 27, (3) by the induction-pipe pressure acting through a pipe 42 on a piston 36 carrying a brake block 37 which under the action of a spring 40 tends to engage the disc 31. Relative movement of the disc against the action of a spring 32 uncovers an additional port leading back to the crank-case, which opening is covered by the hub of the disc when the block 37 is out of engagement. In a modification the needle-valve 27 is replaced by a valve close to the cylinder 13, this valve being controlled by Bowden mechanism from the dash-board.

Title: Improvements in jib cranes for use on overhead runways
IPC: B66C23/72
Filed: 1923-06-08
Abstract: 220,411. Taylor, H. G., and Smith, A. P. June 8, 1923. Apparatus fitted to cranes. - A jib crane F suspended from an overhead runway A is provided with a balance weight N, wholly of a pendulous character, which automatically balances the load so that the crane is not tilted when the load is lifted. A pointer may be attached to the pendulum in order to indicate on a scale the approximate weight of the load. As shown, the weight N is suspended from the crane at M and carries the hoisting motor and gear. The hoisting rope is reeved over pulleys K on the jib and S on the balance weight, so that the first effect of hauling is to move the weight out until its moment about the point of suspension of the jib is approximately equal to the moment of the load. In a modification, the hoisting motor drives through a differential gear of which one member drives the hoisting drum and the other member drives a drum for hauling at the pendulum. The motor may be mounted in the jib structure.

Title: Fluid pressure indicator
IPC: G01L7/16
Filed: 1951-06-27
Abstract: 689,539. Pressure gauges. GRATZMULLER, J. L. June 27,1951 [July 4, 1950], No. 15272/51. Class 106 (ii). A fluid-pressure indicator comprises a casing 1 with end faces 2, 3 of which at least one is removable, a stationary cylinder 7 for a piston 14, the cylinder being on one end face 2 and the piston being subjected to the fluid pressure, a centrally apertured reference member 10 integral with the other end face 3, a bored movable index member 9 slidably mounted on the cylinder 7 and passing through the aperture in the reference member 10, the movable index member having two axially spaced bearing areas 21, means 15 transmitting the movement of the piston 14 to the movable index member 9, removable abutment means 4 between the removable end face and the corresponding end of the casing and elastic means 12 interposed between the reference member 10 and the movable index member 9 to act upon the latter against the action of the fluid pressure. As shown, both the end members 2, 3 are removable, each being pressed outwardly against removable abutment means 4 comprising piano wire sprung into grooves in the casing 1. Fluid pressure fed through a union 6 causes the piston 14 to thrust against the movable index member 9 through an intermediate rod 15 and balls 18, this thrust causing the movable index member 9 to move outwardly through the reference member 10 in a manner compressing the spring means 12. The movable index member 9 has a number of variously coloured rings 24a, 24b, 24c on its outer end, these rings appearing successively as the applied fluid pressure increases. Washers 27 may be interposed under the coloured rings for adjusting the pressure scale of the gauge or to take up mounting inaccuracies. Graduations may be made on the outer end of the slidable member 9 to give an accurate measure of the pressure being gauged. To prevent the piston 14 from being expelled from the cylinder 7 when no pressure fluid is fed into the latter, a drilled plug 30 is forced into the union 6. The gauge may be secured at any desired point by means such as an omega stirrup 31.
