Title: Improvements in or relating to bucket grabs
IPC: B66C3/08
Filed: 1940-12-20
Abstract: 546,085. Bucket grabs. PAGE, M. W. FLOOD-, and WESTWOOD & CO., Ltd., J. Dec. 20, 1940, No. 17951. [Class 78 (iv)] In a bucket grab giving a wide span when open, in which the buckets are pivoted to the ends of a horizontal supporting frame, and are opened out beyond the positions they assume by gravity, the grab is not only closed but is opened positively by the crane through the medium of the hoisting gear, and by sheave block means associated with the buckets. In the construction shown in Figs. 1, 3 and 4, two buckets 2, 3 are pivoted at points 4, 5 to the ends of the supporting frame 1 and are connected by means, such as a train of gearing, so as to move together. The buckets are opened and closed, as well as raised and lowered, by a hoisting rope 14 and a suspension ring 6 which is engaged at times by hooks 7, 8 pivoted to links 39, 40, Fig. 2a, having a pin and slot connection with blocks 35, 36, slidable vertically in guides 37, 38 arranged transversely of frame 1. The opening and closing mechanism consists of levers 9 pivoted at 15 to the buckets and carrying at their other ends pulleys 12 round which the hoisting rope 14 is reeved. The end of rope 14 is connected to frame 1 at 43 and, after leaving pulleys 12, it is led. over pulley 42 on frame 1 through a fairlead to the crane. Fig. 1 shows the grab in loaded condition with the buckets held together by the suspension rope 14 passing over pulleys 12. Further lifting of rope 14 results in the engagement of hooks 7, 8 with supporting ring 6. If rope 14 is now paid out, levers 9 are free to turn about their pivots 15 until they assume a nearly vertical position with the pivots of pulleys 12 above the level of pivots 4, 5. This movement of levers 9 is effected by a rope 27 led over pulleys 29, 31 to pins 33 on the vertically sliding blocks 35, 36 carrying hooks 7, 8. Pawls 16 on levers 9 then engage catches 23 on the sides of the buckets. If rope 14 is then raised, pulleys 12 are drawn together, as shown in Fig. 4, and the buckets are turned about their pivots 4 to the open position when levers 9 assume a horizontal position, the hooks 7, 8 being also released and falling open. As soon as the buckets are lowered on to the material to be collected, pawls 16 are released from catches 23 and levers 9 rotate downwards about their pivots 15 until pawls 16 engage catches 21 on the buckets. When rope 14 is again tensioned, pulleys 12 are drawn together and buckets 2 are closed as shown in Fig. 1. In a modification, the buckets are positively moved from the open to the closed position and vice versa by independent sets of pulleys and hoisting ropes.

Title: Means for regulating the admission of steam to a heat accumulator
IPC: F01K1/08
Filed: 1926-07-17
Abstract: 255,491. Siemens - Schuckertwerke Ges. July 18, 1925, [Convention date]. Steam regenerative accumulators. - Admission of steam to an accumulator mounted in front of heat consumers is controlled in sympathy with its speed of flow in the consumption pipe, and to avoid pendulum-like oscillations the inlet to the accumulator may be arranged so as not to open until the speed of flow has fallen a predetermined extent below normal. Steam flows from a pipe 1 through a throttle valve 2 to a service pipe 3. If the consumption falls, the valve closes somewhat, in sympathy with the increasing pressure at the measuring-point 4 of the valve. When the quantity of steam passing through the valve has fallen below a certain degree, a valve 7 opens under the influence of a measuring nozzle 6 to allow surplus steam to flow into an accumulator 8.

Title: Improvements in the treatment of ammunition cartridge cases with liquid composition
IPC: F42B33/14
Filed: 1943-11-02
Abstract: 576,732. Internally coating cartridge cases. KENNEDY, F. J., and GRANTHAM PRODUCTIONS, Ltd. Nov. 2, 1943, No. 18128. [Class 95] Apparatus for applying liquid composition to the inside of ammunition cartridge cases, comprises means for feeding cases longitudinally and downwardly towards a composition applying member, and means for engaging said member with the cases in succession to deposit the required amount of composition therein. In the drawings cartridge cases are placed base downwards on the loading platform 8, Fig. 1, and pushed forward by hand to conveyer 10 along which they pass in single line to feed arms 21 which push them one at a'time over elevating ram 23. Each stroke of the ram, operated by the crank driven arm 29, raises a case into chute 31, where it is held by retaining members 32 (see Fig. 2) as the ram withdraws. The cases pass round the chute 31 and are presented mouth downwards to spring loaded jaws 34 which hold each case by its base groove above varnish tank 37. The beam 24 on which ram 23 is mounted carries a vertical rod 45 upon which is a fixed collar 46 and a movable collar 49 supported from the fixed collar by spring 48. The collar 46 actuates a double crank 50, the upper arm of which is connected by rod 57 and crank 52 to sleeve 40, and the lower arm of which is connected by rod 53 to ram 38. The upper collar 49 actuates a crank 54 connected by link 55 and crank 56 to vertical rod 57 supporting beam 36 carrying varnish applying member 35. Each upward stroke of ram 23 lifts varnish applying member 35 into contact with the inside of mouth of cartridge cases held in the jaws 34. The spring 48 causes the applying member 35 to dwell in the case so that the varnish runs off the nose of the member and forms a ring- shaped coating in the case. On the return stroke of ram 23, the member 35 returns to tank 37 and the pawls 41 carried by sleeve 40 are raised to engage the base groove of the last case in the chute and lift it out of contact with the case which has just been varnished. At the same time the horizontal ram 38 ejects the varnished case from between the jaws 34 to the delivery guide plates 39.
