Title: A new or improved machine for separating the individual elements of the pairs of a continuous stream of elements superposed in pairs
IPC: B28B13/04
Filed: 1949-06-15
Abstract: 676,302. Conveyers. CARTER, WILKINSON, Ltd., and WILKINSON, H. A. May 24, 1950. [June 15, 1949] No. 16000/49. Class 78 (i). [Also in Group V] In a machine for separating the individual elements of the pairs of a continous stream of elements superposed in pairs on a conveyer, the opposed side edges of one member of each pair are engaged in succession by the travelling surfaces of a pair of rotatable wheels, travelling bands or other members affording travelling surfaces so as to divert that member from the stream.. Tiles or moulded concrete blocks 4 on their moulding pallets 5 are advanced by a belt conveyer 1. The tiles or blocks 4, having been previously loosened from the pallets by heat or other treatment, are lifted from the pallets by a pair of pneumatic or sponge rubber tyred wheels 3 freely rotatable on stub shafts 33 arranged one each side of the conveyer. The tiles or blocks are lifted by frictional engagement by the wheels 3 onto a belt conveyer 6 and smooth transfer is ensured by a pair of power driven vertically disposed belts 20, one each side of the conveyer 6 which are inclined slightly downwardly towards the conveyer 6 and which thus grip the sides of the tiles or blocks and deposit them on conveyer 6. The wheels 3 are adjustable along the stub shafts 33 and are adjustably inclined by angular adjustment of each shaft 33 about a transverse shaft 34, separately or together, the wheels being positioned so as to engage the tiles or blocks without engaging the pallets 5 which continue along conveyer 1. Magnetic means may be used to hold the pallets down on conveyer 1 while separation takes place. The belts 20 are each mounted for both angular and longitudinal adjustment and the individual wheels or belts of each pair can be adjusted towards and away from each other. The end 31 of belt 6 can be raised and lowered. In the Provisional Specification there is described apparatus having power driven wheels 3 each separately adjustable. Instead of belts 20 further pairs of wheels may be used.

Abstract: 1,047,623. Conveyers. FISHER & LUDLOW Ltd. Aug. 2, 1963 [May 2, 1962], No. 16774/62. Heading B7L. A conveyer has two trolley tracks 12, 13' Fig. 1, along which trolleys are advanced by dogs on conveyer elements 11, 14 driven by power units 17, 18, each dog 22 having a trolley driving face 24, Fig. 2, which engage abutments 25, one on each trolley; the tracks 12, 13 meet at a junction J whereat trolleys on branch track 13 are moved on to main track 12. Each driving dog 22 is mounted between two plates 21 and bears on studs 30 and 34. Should a trolley catch up to the dog due to a slow moving chain, then the trolley abutment 25 engages the chamfered face 44 on the dog to pivot the dog about stud 30, the dog dropping behind abutment 25 to drive the trolley which is prevented from further advancement by a stop dog 23 somewhat similar to dog 22. To disconnect drive to a trolley a member on the trolley as described in Specification 1,047,621 moves dog 22 vertically under the guidance of straight faces 36, 37 and studs 23, 30. The stud 34 frictionally engages the face 39 of the dog to prevent unintentional rotation of the dog. The dogs 22 each have a tail 40 on which is formed the faces 24, 44 and which is of V- section at its ends 43, Fig. 9. At the junction J which includes a switch point, the branch conveyer element 14 is offset from branch trolley track 13 so that as a trolley is advanced toward the junction the tail 40 moves laterally relative to trolley abutment 25 and a tail 40 of a dog on the main conveyer element 11 then engages the opposite end of the abutment 25 to take over the drive of the trolley. Should the trolley be moving faster than the main element 11 then abutment 25 engages face 44 to raise the drive dog 22 of the main element which then drops down behind abutment 25.

Patent GB-169911-A (GB)
Abstract: 169,911. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 21, 1920. Blades of the kind that are secured in place by causing the blade roots to bow under pressure, are formed with contacting surfaces reduced in area, so that they are able to support only permissible stresses. Figs. 1 and 3 show a form of blade having a bifurcated root which is pressed around the undercut rotor rim 10. The contacting surfaces are reduced to the narrow strips 16 and the crushing resistance of these strips is sufficient only to balance permissible stresses. A filling 17 is inserted below the blades. In another form, in place of the filling 17, the rotor may be upset to fill the space, and the inner ends of the blades are cut away as shown in Fig. 5, so as to be incapable of sustaining undesirable stresses. The projections A which may be produced on the rotor by the upsetting operation serve to prevent circumferential displacement of the blades.

Title: Improvements in or relating to coin-controlled mechanism
IPC: G07F15/02
Filed: 1936-06-18
Abstract: 477,273. Coin - freed apparatus. BRITISH SANGAMO CO., Ltd., and WESTON, G. E. June 18, 1936, No. 17031. [Class 27] Coin-controlled mechanism is provided with means for testing both the diameter and thickness (including resistance to penetration) of a coin whilst in position in the coin holder, operation of the mechanism being prevented if the coin fails in either test. The invention is described as applied to the prepayment meter described in Specification 445,546 operable at will by any one of a number of different coins, in which rotation of an operating handle 1 causes axial movement of a shaft 10 through a cam 4 and flexibly connected arms 5 and 7, and rotational movement of the shaft through pinions 11, 12 and 13. The shaft, in its axial movement, gauges the diameter of a coin in the pocket 16, the coin, if of a correct diameter, arresting the shaft in a position in which a gapped disc 19 thereon clears one of a series of apertures in a fixed gate plate 23, so that continued rotation of the shaft is permitted and is transmitted through the appropriate section of a multi-toothed pinion 9 to the quantity mechanism. The invention provides a thickness gauging bar 30 pivoted to an arm 29 fast on a shaft 28, and connected through a spring 31 with a loose arm 27 pivoted to a rod 25. A pin 24 on the pinion 13 displaces the rod 25 during the operation of the mechanism, causing the bar 30 to pass through an aperture in a side wall of the coin pocket until it is arrested by the face of the coin, excess movement being taken up by the spring 31. If the coin is not up to the required thickness, or is a soft counterfeit, the shaft 26 turns so far that an element 32 secured thereto displaces a pivoted mask 34 over the apertures in the gate plate 23 to prevent further operation. With a coin of the required thickness, the bar 30 and shaft 28 are arrested before the element 32 engages the mask 34. Specifications 8720/15, and 332,915, [both in Class 27], and 346,282, also are referred to.

Abstract: 1,154,767. Cutting machines. INTERCONTINENTAL MACHINERY CORP. 13 April, 1967 [3 Oct., 1966], No. 17067/67. Heading B4B. [Also in Division G3] A machine for automatically cutting a stack of superposed sheets has a supporting surface for holding the stack and a carriage, longitudinally and transversely movable with respect to the surface in response to remote control signals, which accommodates a power-driven endless cutting band guided by a pair of band guides, one above and one below the supporting surface pivotable in unison in response to remote control signals to orientate the plane of the band along a tangent to the cutting direction defined by the instantaneous movement of the carriage. As shown, Fig. 1, a machine, having a cutting-band 13, is positioned relatively to cloth 12 by an automatic electric control system responsive to amplified signals from a photo-electric transducer 18 following a template 52. The cloth 12 is held stationary by edge clamps and supported by a flexible slotted surface 24 which is held flat between channels 25, 26 and tensioned over rollers 20, 21. The band 13 is mounted on a carriage 14 which is movable transversely by a leadscrew 16 driven by a servomotor 49, the band travelling in a gap between the slots forming the surface. The carriage 14 is movable longitudinally by a leadscrew 15 driven by a servomotor 50. The servomotors are controlled through an amplifier 17 by the transducer 18. The material is held in position during cutting by a spring-loaded pressure plate attached to the carriage. The band is retained, Fig. 2, within guides 60, 61 which are rotatable by gearing 62-65 so that the guides are kept constantly directed along the tangent to the line of cut. The gearing is driven by an actuator responsive to signals from the amplifier 17, Fig. 1, corresponding to the first derivative of the pattern signals. The cutting band 13 preferably consists of a narrow steel band having both edges sharpened to form cutting edges and twisted to form a Moebius strip.
