Title: Improvements in slot meter coin mechanisms
IPC: G07F15/02
Filed: 1933-03-23
Abstract: 416,933. Prepayment mechanism for meters. BROWN, R. T., 12, Tramways Path, Mitcham, Surrey, BUSSELL, A. F., 8, King Gardens, and POWELL, W., 40, Cedarcroft Road, Peverell, both in Plymouth. March 23, 1933, No. 8746. [Class 27.] In meter prepaymentmechanism having quantity mechanism set forward by an amount determined by the diameter of a coin inserted in a rotary coinpocket, initial rotation of an operating handle causes a gauging member in the coin pocket to engage the coin, so that a driving abutment on the gauging member takes up a position determined by the diameter of the coin. The coin holder comprises a plate B, Fig. 4, fixed to, but separated from, a disc A, Fig. 3, carried on a spindle 5 journalled in a sleeve 4, Fig. 2, connecting an external handle (not shown) with an operating member 2, Fig. 2, and supported by a wall 3 of the casing. The gauging member 12 is pivoted at 13 to plate A, and is coupled by a pin 11 to the operating member 2. Upon initial rotation of the external handle and member 2, the gauging member 12 forces a coin against a lever 17 and assumes a position dependent on the diameter of the coin ; a pin 18 on lever 17 enters a recess 27 in a plate 25 pivoted to plate D, which is then rotated by a spring 28 to withdraw a catch 30 pivoted at 35 to plate B out of engagement with a co-operating catch member 32, so as to permit continued rotation of the operating handle to rotate the coin pocket. At a point in the rotation of the coin pocket dependent on the diameter of the inserted coin, the driving abutment 15 on the gauging member 12 engages one of a number of pins 60 on a rotatable plate 48 having driving engagement with the coin side of the quantity mechanism through a pawl 50, ratchet wheel 51, and gear wheels 52, 53. Pins 43 on plate B simultaneously rotate a mutilated gear 58 through half a revolution, to close the supply switch, through a slotted plate 45, ratchet and pawl mechanism 56, 57. At the completion of the rotation of the coin pocket, the coin is discharged, and plate 25 is tilted by a fixed stop 40 so that lever 17 and catch 30 resume their normal positions shown. The coin pocket is returned to its normal position when the handle is released by a spring operating on the handle, and engagement between pin 15 and a projection 61 on plate 48 simultaneously restores the latter to its normal position. Backward rotation of the coin pocket before the completion of its rotation is prevented by a pawl 20 which engages ratchet teeth 9 in the wall 3 when lever 17 is engaged by a coin. Unsuitable coins may be removed from the coin pocket by rotating a pivoted plate passing through slots 36, 38 in plates B and A, and forming the bottom of the pocket, by means of an external knob. In a modified construction, the pins 60 are replaced by arcuate grooves B of varying length in the plate 48 terminating in a radial groove in which the abutment 15 slides during movement of member 12.

Title: Improvements relating to the Control of Alternating Electric Current Induction Motors.
Inventor: BROOKE WILFRID
IPC: H02K17/30
Filed: 1916-06-21
Abstract: 107,240. Brooke, W. June 21, 1916. Systems for alternating- current motors only.-An induction motor with a flywheel is controlled by the variation of resistance in the secondary circuit and slip relays controlled by the secondary current act to increase the resistance and slip when the current exceeds a predetermined limit. The resistances 5, 6, 7 are connected to the slip rings 4 and are cut out in sections by electro-magnetic contactors 39-58, the actuating windings of which are controlled by accelerating relays 69-77 which close in succession as the secondary current drops. Each relay is mechanically interlocked with the contactor on its resistance tap to prevent it from closing while the contactor is open. Relays 90-94 have windings 95-99 connected in series with the last five steps of resistance, and contacts normally closed in series with the actuating coils of the last five contactors. If the current during the running of the motor exceeds a predetermined limit, the relay 94 will be lifted and the contactors 57, 58 consequently open to insert a section of resistance. The relays 93-90 operate in the same way until the current is reduced to the lower limit. The relays are constructed to close at a lower value of current than that required to open them. One form is shown in Fig. 3. The movable contact 107 of the relay is carried by a bell-crank lever 103 provided with adjustable weights 109, 110. A rod 102 attached to the lever carries the core 101 of the winding 100 and the position of the core can be adjusted by means of the nut 111. The centre of gravity of the moving parts is nearer to the pivot 105 in the open position of the relay than it is in the closed posibion, so that the lower limit of current will close the relay.

Title: Improvements in pencil sharpeners
IPC: B43L23/04
Filed: 1924-04-07
Abstract: 224,457. Weiler & Co., Ges., and Weiler, E. April 7, 1924. Pencil-sharpeners.-In pencil-sharpeners having one or more cutters revolving about their own axes as well as about the pencil point, means are provided to impart in addition an axial reciprocating motion to the cutters. A milling cutter 21, Fig. 1, may be freely mounted on a shaft 20 moved around the pencil point by a handle 12. One end 23 of the shaft 20 is screwed to a disc 8<1> on the handle 12 and the other end passes through an aperture in a plate 19 carried, together with a conical shell 14 for the pencil point, on an arm 13 on the disc 8<1>, the parts 19, 13, 8<1> revolving together. As the shaft 20 is carried around the pencil point, the clutter 21 is revolved about the shaft 20 by the engagement of slots 22 in a shell carried by the cutter with a fixed inturned toothed flange 9 secured to a plate 6. The plate 6 is secured to a table by a screw clamp 5 and carries a transparent casing 7. The plate 19 is obliqus to the shaft 20 and co-operates with a roller 25 on the cubter pressed against it by a spring 24 so that an axial reciprocating movement is given to the cutter as it revolves about the shaft 20. The inclination of the shaft 20 is adjustable by a screw 26 and the aperture through which the pencil is inserted and held by hand is varied by means of an apertured plate 17 pivoted to the plate 19 at 15. In a modification Fig. 3, three symmetrically-arranged cutters 21a, 21<b>, 21<c> are freely mounted on shafts 20 carried by an offset plate 23a on the revolving disc 10. Springs 24 press balls or rollers 34 at the ends of the cutters against a fixed oblique plate 28 carried by arms 29 on a fixed part 8<a>. The part 8<a> is slotted at 9<a> to engage pinions 22a on the cutters to impart to them a rotary movement about the shafts 20 as the shafts move round the pencil point, the plate 28 producing in addition an axial reciprocating motion. The cutters are formed with bearings 33 resting in notches in a spider frame revolving on a bush 30 on the plate 28, the pencil 35 passing through the bush 30.

Title: Improvements in connection with the Starting Mechanism of Internal Combustion Engines.
IPC: F02N15/06
Filed: 1916-09-07
Abstract: 109,033. Tangyes, Ltd., and Robson, J. Sept. 7, 1916. Starting.-The valve 23 which admits compressed air for starting is actuated by means of an arm 24 connected by a link 25 or links to a handle 26 on the same side of the engine as the cam shaft 21. In the form shown, the handle 26 is supported on the spindle 27 of the handle 28 for putting the liquid-fuel pump 29 into and out of action. The pump is put out of action, when the engine is running without load, by raising the handle 28 into the position shown in dotted lines; the cam action of the spindle 27 depresses the end 31 of the pump-operating lever 32 and prevents its operation by the cam 34. The handle 26 is then moved into the position shown in dotted lines, opening the starting-valve and allowing air compressed in the engine cylinder to pass into a storage reservoir. At starting, the handle 28 is in the position shown in full lines, allowing the fuel pump 29 to be worked, and the starting- valve 23 is opened by means of the handle 26 to admit compressed air to the cylinder.

Title: Counterbalancing mobile cranes
Inventor: LEAVESLEY LEONARD ARTHUR
IPC: B66C23/72
Filed: 1963-03-08
Abstract: 1,020,635. Counterbalancing mobile jib cranes. LEAVESLEY ENGINEERING Ltd. Feb. 6, 1964 [March 8, 1963], No. 9230/63. Heading B8B.  A counterweight 22, Fig. 1, is moved along a beam 25 by a ram 24 so that loads lifted by the crane 11, 15 are counterbalanced. The supply of pressure fluid to the ram 24 is controlled by a pilot valve 31 which is operated when the tower 11 pivots about a pin 32 due to the load being lifted. Movement of the tower is damped by a hydraulic damper 34 and is limited by a stop 33. Vane or friction type dampers may be used. When a load is lifted the tower 11 tilts and through a system of levers, Fig. 2 (not shown), moves a piston 31c, Fig. 3, to the right. This prevents fluid flowing through the valve 31 from a port 31e to a port 31d thereby causing a piston 43a to be displaced to the left and liquid to be supplied to the right-hand side of the ram 24. The latter contracts and pulls the counterweight 22 up the beam 25. As the weight reaches a balance point the piston 31c is returned to its mid-position as are valve 44 and piston 43a, thus hydraulically locking the weight in position. The reverse series of operations occur when the weight is removed. The tower and the jib are telescopic and are extended by rams. The hoist winch is driven hydraulically.
