Abstract: 1448422 Machinery safety devices JOSEPH DAWSON Ltd 5 Feb 1975 [20 Feb 1974] 7644/74 Heading F2J A movable safety guard 2 for a carding machine has locking means 7, 8 adapted to lock the guard 2 in the guarding position, which locking means 7, 8 is controlled by manual means 6, 11 and is associated with an on/off switch 18 of the machine, the manual control means 6, 11 being arranged so that when operated to unlock the guard 2 it initially operates the switch 18 to switch off the machine but opening movement of the guard 2 is still prevented until the control means 6, 11 has been operated for at least a predetermined time interval after disablement of the machine to ensure that the heavy moving carding machine parts are completely at a standstill before the guard 2 is finally released by the manual control means 6, 11 for access to the machine. As shown, the locking means comprises a T-shaped latch 7, carried by the guard 2, which engages slots 17 in a latch bar 8 fixed to the machine, the latch 7 being operated by a manually rotatable handle 6 via a reduction gear-box 11 and a snail cam 15, rotation of the handle 6 initially raising the latch 7 to operate the on/off switch 18 to switch off the machine, and further rotation of the handle 6 effectively slowly raises the latch 7 to finally clear the slots 17 to release the guard 2 at which point the machine will be at rest. A second switch 19 is arranged in series with the switch 18 so as to break the circuit when depressed as the T-latch 7 is raised in slots 17 whereby if the switch 18 is faulty the machine is nevertheless disabled and slows down during the period the switch 19 is depressed, the fault being indicated when the machine re-starts after switch 19 is released by the raised latch 7. As shown, the guard 2 is pivotally supported on underswing arms (4) Fig. 1 (not shown). In the alternative embodiment of Figs. 5 to 7 (not shown) the guard (23) is supported on an overhead track (26). The locking means comprises a vertically slidable non- rotatable rod (30) which is carried by the guard (23) and telescopes within a tube (37) fast on the track (26) to lock the guard (23) in position, with the upper end of the rod (30) engaging an on/off switch (39, 40) of the machine. The locking rod (30) of the guard (23) is again controlled by a manually operated handle (34) which via a gear-box (33) and a screw device (31), on the end of the locking rod (30), slowly lowers, i.e. withdraws the rod (30) from the tube (37) to initially release the switch (39, 40) to switch off the machine, whilst the locking rod (30) is still in locking engagement with the tube (37) to prevent the guard (23) being opened until it is finally lowered clear of the tube at which stage the machine is at rest and ready for safe access thereto.

Abstract: 279,317. British Furnaces, Ltd., and Smith, E. W., (Surface Combustion Co.). March 22, 1927. Metal-heating furnaces.-In furnaces or kilns of the kind in which two heating chambers in the same structure have one wall in common the structure also comprises two producers, either or both of which can supply gas to each chamber, and two recuperators supplying secondary air to the chambers at the place where the producer gas enters. In the reheating furnace shown the wide sheet-heating chamber A and the narrow bar-heating chamber D are arranged side by side, with the producers B, E at the end of the sheet heating chamber. A passage 7 in the common wall 6 of the producers, normally closed by a sliding door 8, allows the gas generated in one producer to flow into the other. Recuperators C, F, arranged-beneath the chambers, supply secondary air to the chambers A, D respeectively through passages 18, 53 in dividing walls 10. 51 over which the gases from the producers B, E pass to the respective chambers. The hot gases after traversing the chamber A descend through ports 24, pass through ducts 30 beneath the chamber A and through the hollow bricks of the recuperator C, and are led through a passage 36 to a chimney. From the chamber D the hot gases descend through ports 62 leading directly to the recuperator F, from which they pass through a passage 69 to the chimney. The cold air enters the recuperators C, F at 23, 56 respectively, and circulates around the hollow bricks, and a passage 74 normally closed by a damper 75 allows hot air from one recuperator to flow into the other. Work doors 26, 70 are provided for the chambers, and sloping tracks 58 are arranged in the. bar heating chamber D to allow free circulation of hot gases around the bars.

Filed: 1931-03-17
Abstract: 363,571. Printing-surfaces. FOSTER & SONS, Ltd., J., WILKINSON, M. L., and BRADSHAW, R., Soho Foundry, Preston. March 17, 1931, No. 8188. Addition to 351,970. [Class 100 (ii).] The means for locking printing-surfaces on cylinders according to the parent Specification is modified by the provision of operating-mechanism for the geared spindles 4, Fig. 1, and sleeves 5 carrying the locking-dogs 2, 3 for the printing-plates &c. 19, 20, comprising a spindle 45, Fig. 3, rotatably mounted in a recess in the printing-cylinder 1 and supported in the cylinder endplate 15 so as to be capable of longitudinal movement; clutch teeth on a gear wheel 46 fixed to the spindle can engage teeth on a gear 47 loose on the spindle, and a spring 48 normally presses the spindle so that the clutch teeth are in engagement, while a locking-member is provided to hold the spindle in the position in which the gear wheels are declutched. In the former case, rotation of the squared end of the spindle 45 drives gears, as shown in Fig. 3, to rotate both the sleeves 5 and the spindle 4, thereby moving both plate-locking dogs 2, 3 ; when the gear wheels 46, 47 are declutched, rotation of the spindle 45 drives only the sleeves 5 to operate the dogs 3. The locking-member described comprises a spring- pressed plunger 49, Fig. 5, through which passes a reduced portion 92 of the spindle 45, forming shoulders 45c adapted to engage shoulders 49a on the plunger 49. When the plunger 49 is depressed, the spindle 45 is released and moves back under the action of the spring 48 to engage the gears 46, 47. For declutching, the spindle 45 is pressed towards the cylinder until the plunger 49 rises to lock the spindle in the position shown in Fig. 5. The above operating-mechanism serves for the spindles and sleeves on one half of the cylinder and is duplicated on the other half.

Filed: 1939-03-14
Abstract: 526,384. Driving-gear; two stroke engines; valves. ISTAD, L. J. March 14,1939, No. 8227. Convention date, March 15, 1938. [Classes 7 (ii) and 7 (vi)] In an engine having cylinders arranged around and parallel to a central shaft and in which the pistons drive through a swash plate, a cylindrical valve surrounds the shaft and controls the admission of scavenging air and of air-fuel mixture to pumps located at the ends of the cylinders remote from the combustion chambers. In the construction shown in Fig. 1, oppositely-moving pistons are connected to a pair of swash plates and one of the pistons is formed of two diameters, the part of larger diameter compressing a fuel-air mixture and scavenging air with its opposite faces ; 75 and 73 are the separate scavenging and mixture pumps respectively. Air for the scavenging pumps enters through a passage 93 and is discharged through a port 90 after traversing groove 105, and a slot 106 in the valve (Fig. 5). On the return of the pump piston compressed scavenging air traverses a passage 71 to the cylinder. Fuel-air mixture is drawn into the pump through a port 94 in the cylinder block, and a passage 110 and ports 111 and in the valve 91. During the return stroke of the piston, ports 112 and 113 in the valve which are connected by a transverse passage are brought opposite ports 91 and 92 in the pump and cylinders respectively and allow the transfer of mixture to the combustion space. The valve rotates with the central shaft to which it is connected by screws 97. The swash plates 58, 59 are each mounted on an inclined crank 35 by two split sleeves 63 and a spacing sleeve 64, the parts being held in place by a screwed ring 66 and a thrust ring 65. The thrust ring bears against a ring 41 on the end casing of the engine. The swash plate is held against rotation by arms 55 on the plate sliding between inwardly projecting curved lugs 87 carried by the end casing. The swash plates may be set out of phase.

Title: Improvements in voltage-regulators for alternators
Inventor: D ORNANO NAPOLEON CUNEO
IPC: H02P9/14
Filed: 1951-04-13
Abstract: 704,683. Automatic voltage control systems. SOC. D'APPLICATIONS ET DE FABRICATIONS INDUSTRIELLES S. A. F. I. April 13, 1951, No. 8631/51. Class 38 (4) The output voltage of an alternator having an auxiliary high frequency alternator as its exciter, is controlled by a torque motor responsive to the output voltage and adjusting an induction regulator controlling the excitation of the field of the exciter alternator. In one embodiment, the torque motor consists of a rotatable conducting cylinder 12, Fig. 1, in a three phase field energized from the output of the alternator 1. The cylinder 12, acting against a spring 8, adjusts the moving coil 17 of an induction regulator, the stator of which is energized by the exciter alternator 6. The output of the coil 17 is rectified at 16 and applied to the field of the exciter alternator 6 which energizes the main alternator field over a rectifier 15. In a modification, Fig. 5 (not shown) the regulator' assembly moves laterally instead of rotating. In a second embodiment, Fig. 6, the induction regulator 10 is driven by a moving coil movement 21 energized from the alternator output over a rectifier 19. The regulator 10 consists of a rotatable magnetic shunt 22 variably linking the input windings 34 with the windings 35 which supply the field of the exciter alternator 6 over rectifier 16. Positive feed back from an auxiliary winding 36 to the operating coil 21 via rectifier 20 increases the sensitivity of the system. In a modification, Fig. 8 (not shown), the feed back winding 36 is disconnected and short circuited through an adjustable resistor so as to prevent hunting.

Title: Device for spreading strewable material during travelling
IPC: A01C15/00
Filed: 1954-03-26
Abstract: 763,985. Manure distributers. VAN DER LELY N.V., C. March 26, 1954 [April 2, 1953 ; July 27, 1953 ; Oct. 22, 1953], No: 8880/54. Class 6(1). A fertiliser-distributer of the kind in which the powder is discharged through apertures in a hopper and spread over a strip of ground of considerably greater width than the track of the ground wheels of the supporting vehicle, is characterised in that the machine includes a plurality of oscillating members which receive the material from the hopper and collectively distribute the discharged powder evenly over the ground. In Fig. 1, the device is wheelless and is carried by arms 3A, 3B, secured to the tractor back-axle. The hopper is of stepshape in plan with vertical walls 9A, 10A, 11A, 9B, 10B, 11B, arranged in echelon. The base of the hopper is spaced below the walls and is in two overlapping parts 16A, 16B together defining a parallelogram and being reciprocable in opposite directions by a mechanism 20 driven from the tractor power take-off. Grooves 27 assist the flow of material transversely during reciprocation and adjustable slides are arranged on the vertical hopper walls to control the rate of discharge. The portions 26B beyond the track of the tractor-wheels 4 may be hinged back, for transport. In Fig. 5, the hopper is in two halves 33A, 33B arranged behind one another but spaced transversely. The material gravitates past adjustable slides 54A on the vertical side-walls 53A of the hoppers to fall on to inclined plates 35A, 35B which are reciprocated laterally by mechanism 43, the plates being linked together by a loose bolt 47 which causes them to impart jerks to one another. The plates 35A, 35B are triangular in plan the outer sections being hinged at 57A, 57B. In Fig. 13, an adjustable slide 167 is mounted on the rear wall 166 of a hopper 162 and a serrated comb 169 is reciprocated adjacent to the gap left by the slide. The discharged material is picked up by projections on a roller 172 and is thrown against a cover 179 whence it falls uniformly into fluted gutters 180 which are dragged along with their lower ends in contact with the ground. These lower ends may carry eccentric rollers to impart a jigging motion to the gutters. In Fig. 15 rotating discs 196 carry the material away from the hoppers 194 and paddles on a rotating shaft 199 impel the fertilizer into flutes in an inclined reciprocating plate 206, the motion of the parts being derived from the land-wheels 191. To ensure comminution of the material small plates carrying pins or projections are mounted adjacent to the outlets of the gutters or flutes.
