The catches C are simultaneously operated by a handle G, which first lifts them by means of the eccentrics E, E<1> and then, by rotating the cranks H, J to engage pins C', rotates them free of their lugs D, D'. The catches are restored by spring plungers K engaging their tail ends C', while arms C<2> thereon engage the lid to assist the initial opening movement. Padlocking means are also provided to prevent unauthorized use, and if the box is mounted high up, the handle is extended so as to be within reach from the floor level.

Title: Improvements in or relating to agricultural implements
IPC: A01D80/00
Filed: 1959-08-28
Abstract: 931,423. Agricultural implements; hay-making machines. C. VAN DER LELY N.V. Aug. 28, 1959 [Sept. 9, 1958], No. 29477/59. Classes 6(1) and 6(3). A wheel-operated lifting appliance for an agricultural implement comprises actuating means, such as a housing 23, which rocks about an axis 24 to raise and lower the tools 8, through a crank-pin 22, connecting rod 17 and leversystem 11, the housing being associated with stops which lock it at both ends of its travel, the actuating means including epicyclic gearing 32, 33 which can be connected to the housing 23, to rotate it, by the axial movement of a locking device 41 which locks together the wheel-hub 25 and the planet-carrier 34, thereby transmitting movement to the housing 23 through a ring-gear 35A on the housing. The arrangement is shown applied to a haymaking machine having rake-wheels 8 mounted on a main beam 1 which is supported each end on a wheel-assembly 11, 12, each assembly comprising a swivel-wheel 9, 10 of which the vertical spindle, such as 29A, is mounted in a sleeve 30 connected to the main beam by parallel links 11A, 11B, 11C, 11D, one link, 11D, being extended beyond its pivot and connected to the rod 17 and another, 11C, having a cranked extension 18 connected by a rod 19 to the assembly 12 at the other end of the beam. The wheel 9 is mounted on a hub 25 free on an axle 28, the housing 23 being rotatable on the outer end of the axle. The intermediate portion of the axle is slotted vertically at 40, enabling a key 41 to be slid through it to lock the planet-carrier 34 to the axle. A longitudinally-movable shaft 53 extends through the axle, through the slot 40 and through the key 41 and carries a locking bar 48 on its outer end, the bar normally engaging lugs 51 on the housing to prevent rotation thereof. A pull on a cable 59 moves the shaft 53 axially, against springs 63, 68, releases the bar 48 from the lugs 51 and pushes the key 41 through the slot 40 to lock the planet-carrier 34 to the axle 28, so that rotation of the wheel 9 rotates the housing 23 and raises the beam 1 through the rod 17 and the linkages 11, 12. Disengagement is effected by contact of the bar 48 with lugs 46, 47 on the housing which push it rearwardly to re-enter the lugs 51, the key. 41 simultaneously disengaging the axle and planet-carrier, the springs 63, 68 finally restoring the various parts to their former positions. As shown in Fig. I, the rake-wheels are carried on short stub-shafts 2, 3, 4, 5, two further stub-shafts 6, 7, being provided, to receive a displaced pair of rake-wheels (dotted position) for swath-turning. Specifications 931,424 and 931,425 are referred to.

Abstract: 839,328. Sliding bolt fastenings. KELSALL, A. F. Oct. 10, 1957 [Sept. 27, 1956], No. 29484/56. Class 44 A fastening comprises a fastening bolt 7 and a hand operated spindle 6 having a cam 9 thereon for actuating the bolt by axial movement of the spindle, the bolt being pressed by a spring 8 towards the spindle and the cam being adapted to project and hold the bolt projected, the cam being moved when the spindle is moved axially to allow the bolt to be spring retracted. The spindle is provided with knobs 5, 5a at its end by which it can be moved axially, the knob 5a being secured to the spindle against axial movement but so that it is free to rotate. The knob 5 is fixed to the spindle by a screw 11 and the head of the screw engages a slot 12 in in a hollow sleeve 2 of a rose plate so that when the knob is rotated the spindle cannot be moved axially by the knob 5a which is the outside knob.

Title: Improvements in and connected with the separation of the coverings of kernels of nuts from same
IPC: A23N5/00
Filed: 1919-11-28
Abstract: 162,326. Moon, R. B., and Adams, F. E. Nov. 28, 1919. Cracking nuts.-A machine for opening nuts consists of means for exerting pressure on a nut, by means of blunt bevelled-edge tools, at rightangles to its longitudinal axis, so that the nut becomes distorted and eventually bursts. The machine, which is particularly intended for cracking Babusu Cocos, has two tools 1 arranged opposite one another, one being fixed while the other is moved in and out by a reciprocating rod 2, Fig. 1. The connection between the rod 2 and the tools consists of a pin 14, which slides in a longitudinal slot 13 in a tail-piece attached to the cutter, and by a member 5, hinged to the rod 2, which engages the rear of the tool. The member 5 has a lug 9.which is loosely engaged by a rod 8 that is pressed rearwardly by a spring 7. Thus when the rod 2 moves forward, the member 5 engages the rear of the tool and presses it against the nut, the pressure between the member and the tool being sufficient to prevent the member 5 from being raised by the spring 7. When the nut bursts, the tool is jerked forwards thus allowing the spring 7 to disengage the member 5 and preventing the rod 2 from forcing the tool into the kernel of the mit. The tools 1 are bevelled, and are curved, as shown in plan in Fig. 2, so that the points of the tools first enter the shell and assist in bursting it. Stripper plates 16 overlie the tools, one of them being free to move longitudinally and being pressed forward by a spring 17.

In a process for hot shaping metals or metal alloys by drawing or extruding, a metal blank is heated in a salt bath and coated with salts prior to feeding to the shaping tool, the salt being maintained on the surface of the metal before, during and after the shaping. A thorilun blank 16 is heated in a salt melt 17 to a temperature of 800‹ C. and is subsequently drawn through a die or dies submerged in the melt by drawing jaws 19. The wire product is subsequently further drawn. The drawing die which if submerged is of a hard metal or ceramal, may also be located above the surface of the melt in which case the wire product is preferably covered with salt melt by suitable means. Bars, channel-irons and tubes are extruded from U-section ingots preheated to 950 C. in a salt bath. The extrusion tool is also preheated in a muffle furnace to 750‹ C. approximately. A molybdenum lined ingot container 25 receives the heated ingot which is extruded through a die 23. During extrusion ladled into the channel 21 and is delivered through nozzles in passages 24 in a die holder 24 to cover the entire surface of the extruded article and thus prevent oxidation. Alternatively the salt may be poured on to the extruded metal at the extrusion outlet passage. The salt bath may contain chlorides, carbonates or phosphates particularly of the alkali metals or the alkaline earth metals. Other metals suitable for working by the process are uranium and its alloys and alloys of zirconium and chromium. Sheet, bar or wire products may be drawn or extruded according to the invention.

Abstract: 152,964. Eclipse Machine Co., (Assignees of McGrath, W. L.). Oct. 22, 1919, [Convention date]. Turning-gear.-In an engine-starter comprising a driving-member or pinion 6, mounted for movement along a motor-driven shaft 3 and rotation with the shaft, the member 6 is driven through a friction clutch 10, 11 and is cushioned by a yielding member such as a light spring 18 acting independently of the clutch. In the form shown, the shaft of the electric starting-motor 1 has a plain part 3 carrying the pinion 6 and a threaded part 2 carrying a nut 5 connected to the pinion by a barrel 8 and the plate clutch 10, 11. A heavy spring 17 is interposed between the pinion and the clutch, and the clutch plates are retained by a spring ring 40. If the teeth of the pinion 6 clash with those of the engine fly-wheel 7 in the axial movement, the light spring 18 is compressed and the clutch plates slide in slots 12 in the barrel 8 and grooves 13 in the pinion, this relative movement being limited by collars 15, 16. In a modification, the starter pinion is threaded upon a screwed sleeve, which encircles the shaft of the starting motor and is driven through a barrel such as 8 and a plate clutch, one set of plates being carried by a hub secured to the motor shaft. A heavy spring such as 17 acts on the clutch and a light spring such as 18 cushions the screwed sleeve.
