Title: Improvements in or relating to hoist attachments for facilitating access through hatchways and similar confined openings
IPC: B63B27/10
Filed: 1951-06-28
Abstract: 714,848. Hoist attachments for facilitating access through confined openings. MORAN, F. J. May 16, 1952 [June 28, 1951], No. 15344/51. Class 78 (4) To facilitate access to part of a bold or other chamber remote from a hatchway a load hook is mounted for traversing movement along a runway suspended, e.g. from the hook of the crane, and maintained substantially horizontal by a counter load. As illustrated the hook is carried by a trolley 21 (Fig. 8) traversed along a I-section runway 19 which telescopes into a hollow beam 10 and the counter load is applied to an arm 30 which telescopes outside the beam 10. The runway 19 is supported by its upper flanges on rollers 20 (Fig. 3) within the beam 10 and by a trolley 25 (Fig. 8) secured to the runway and provided with wheels 26 which bear on the outwardly directed flanges (see Fig. 3) of the beam 10. The lower flanges of the runway 19 are partly cut away to define a track for the trolley 21 which is held captive by a vertical plate at the outer end of the runway. The arm 30 includes side plates 31, 32 (Fig. 4) spaced from the sides of the beam 10 by pressure plates 41 against which the side plates may be adjustably clamped by bolts (not shown). A retaining member secured to the lower flanges of the runway 19 may embrace the lower flanges of the beam 10, or may carry rollers bearing on these flanges, to prevent the sides of the beam from splaying. When the device is being raised or lowered through a hatchway the runway 19 and the arm 30 are locked in their retracted position by a bolt 39 (Fig. 4) passed through registering holes in the runway, the arm, and the beam 10 and engaging also notches 40 (Fig. 8) in the trolley 21 to retain it beneath the lifting shackle 28 by which the device is suspended. An indicator (not shown) on the lug to which the shackle 28 is secured indicates whether the device is horizontal. Hooks and pulleys may be provided for extending and retracting the runway 19 and the arm 30 and for propelling the trolley 21, and an eye 27 on the runway 19 facalitates positioning of the device. The counter load may be provided, as shown, by a winch 42 in the hold which is connected to an eye 35 on the arm 30. Block and tackle may be suspended from the hook on the trolley 21. Preferred proportions for the runway'19, the arm 30, and the extensions of these members are given in the Specification.

Title: Improved spark plug manufacture
IPC: B22D13/00
Filed: 1942-11-06
Abstract: 561,118. Sparking plugs. AC-SPHINX SPARKING PLUG CO., Ltd., and CORBIN, D. H. Nov. 6, 1942, Nos. 15726/42 and 845/43. [Class 7 (iv)] [Also in Group XXII] In making spark plugs for internal-combustion engines by moulding the core of the central electrode in position in the bore of the insulator, this is heated to render the metal, which is to form said core, molten or plastic, and then centrifuged. A machine for carrying out this process has a spider 32 carried by a vertical axis 20 which is reciprocated by a piston 24, rollers 84 of the spider engaging grooves 85 of a fixed indexing cam 86 whereby the spider is rotated through 60 degrees at each reciprocation. The spider carries six spindles 33 each having pivoted holders 36 for the insulators at their lower end and a long pulley 34 and occupying successively positions A ... F, Fig. 4. The shaft 53 of an electric motor drives slow speed and high speed belts 39, 40 through worm and belt gearing 51, 48, 62, Fig. 1, and a cam 75 through belt and worm gearing 66, 73. The cam acts on a valve 31 to admit air periodically into a reservoir 28 thus forcing oil therein into the cylinder 25 to raise shaft 20 and air below six pistons adapted to lift the hoods 38 at stations F and A to expose the holders 36. The rising shaft 20 strikes a pin 82 to break the connection 79 between the cam follower 76 and valve 31 so that this is reversed by a spring and the shaft and hood supports fall. A spring then remakes the connection 79 when the cam 75 releases the follower 76. At the station F finished insulators are replaced by fresh ones containing platinum tips and inserted lengths of copper or silver rod. A is an idle station, but at each of the stations B and C the pulley 34 is in contact with the slow belt 39 and the insulators are lowered into an annular electric furnace 89 which is closed by the hood 38. At the station D the pulley 34 comes in contact with the high speed belt 40 so that the holders 36 swing out into horizontal position to expel air from the molten metal and force this to engage the bores of the insulators closely. At the station E cooling takes place. In an emergency, the electric motor can be stopped and other valves manipulated so that the shaft 20 and hoods 38 are lifted and kept in raised position. Undesired freedom of the holders 36 is prevented by tongues 351 passing through them and frictionally engaging one side thereof.

Title: Improvements in bearings for the wheels of mine tubs and like vehicles
IPC: B60B37/10
Filed: 1933-05-31
Abstract: 419,084. Bearings for wheels. DELCO-REMY & HYATT, Ltd., and CREWE, W. A., 111, Grosvenor Road, Westminster. May 31, 1933, No. 15727. [Classes 12 (i) and 144 (i).] Axial displacement of a wheel b in both directions is prevented by a radially slotted thrust washer g engaging a groove f in the axle a and clamped between the end of the wheel hub c and a shoulder on a screw hub cap h. The cap h is prevented from working loose by a spring ring m having axially and oppositely disposed ends n, o which engage respectively between two of a series of ribs l on the hub and between the wheel spokes or other projections on the wheel hub. The bearing is preferably fitted with Hyatt rollers, but balls may be used. The inner end of the hub is fitted with a labyrinth packing device comprising two interfitting channel-section rings i, j, one in the hub and the other on the axle. The flanges of these rings may be provided with grease grooves or as shown with grooves for packing material. Another form of packing described in the Provisional Specification consists of a conical felt or other packing ring engaging the axle. This ring is held between a rigid and a dished spring annular disc which abut a shoulder in the hub.
Patent GB-729929-A (GB)
Title: Improvements in or relating to hook positioner
IPC: E21B19/04
Filed: 1952-06-23
Abstract: 729,929. Hooks. GAINES, W. P. June 23, 1952, No. 15746/52. Class 89(2). Hook-assemblies in which the hook proper is mounted to swivel in a supporting member, are provided with means for biassing the hook into a particular angular relation to the support member when the hook is free from load. As applied to a hook for use in well drilling, such as described in Specification 632,575, the casing 2, Fig. 16, of the supporting member is formed with a cam track 32 that is engaged by a follower roller 52 carried by a lug 48 on a ring 40 mounted on a collar 36 secured to the hookshank 6 by a cross pin 38. The ring is supported on the collar by a shoulder and retained by a circlip 46. Teeth 54 on the collar are engaged by a number of corresponding teeth on a plunger 56, Fig. 6, slidable in the lug 48 under control of a hand lever 60 pivoted in the lug at 62 and having a pivoted plunger 76 with a spring that forms a load-and-pin device for biassing the lever into its extreme positions, in one of which a part cylindrical surface 64 locks the plunger 56 with its teeth in engagement with those in the collar, and in the other position the plunger engages the boss of the hand lever. An eye 72, surrounding the plunger 76 with lost motion, and carried by the plunger 56, ensures the withdrawal of this plunger from the collar during the last part of the movement of the hand lever, enabling the position of the ring 40 to be adjusted relatively to the collar and so altering the position to which the hook is biassed. In this position the collar 52 is received with clearance in a slight recess 84 of the cam surface, contact of the collar 36 with the bottom of the casing 2 preventing the collar from bottoming in the recess and leaving the hook with a small amount of angular freedom when in the biased position. The roller may be carried by the casing and the cam surface by the hook. In a modification in which the spring 20 is omitted, the hook is supported by the nut 114, Fig. 8, on its shank, engaging the ball thrust bearing 108 and the follower roller 120 is carried by a spring-plunger 124 sliding in a casing 128 welded to the side of the hook body. The cam track 118 is supported by a ball race 130 on the body 102 of the supporting bail 104, to provide angular adjustment with locking at 144. In a further construction the cam is in the form of an eccentric carried by the support and the roller is mounted on a spring arm carried by the hook and moving in a plane transverse to the axis of the swivel.

Title: Device in connection with self-draining centrifugal bowls
IPC: B04B7/08
Filed: 1931-05-29
Abstract: 362,329. Centrifugal separator bowls. AKTIEBOLAGET SEPARATOR, 8, Fleminggatan, Stockholm. May 29, 1931, No. 15764. Convention date, June 5, 1930. [Class 23.] A centrifugal bowl 1 has central holes 9 communicating with a recess 8 in the bowl base, so that the bowl is drained as soon as its speed of rotation drops to a sufficiently low value. Clogging of the holes 9 is avoided by the provision of a perforated sleeve 10 with a conical part 11 on the bowl hub. Any slime which collects on the sleeve will be thrown off centrifugally when the bowl speeds up again. Where the sleeve is only used to prevent the holes 9 from being clogged while the bowl is being cleaned, it can be pushed into position down the bowl hub after the distributer 4 has been removed ; in this case it is not necessary for the sleeve to be perforated.

Patent GB-332987-A (GB)
IPC: F41A9/37
Filed: 1929-05-22
Abstract: 332,987. Herlach, F., and Rakula, T., (Assignees of Rheinische Metallwaaren-und Maschinenfabrik). Jan. 31, 1929, [Convention date]. Addition to 316,645. Loading-appliances.-Relates to firearms provided with two magazines which are automatically put in action one after the other, as described in the parent Specification, and consists mainly in so arranging the magazines that the one in action projects into the path of movement of the feeding members of the breech mechanism while the other is in a slightly retracted preparatory position, the first one being automatically ejected when empty and the second one being then shifted to operative position. As shown in Fig. 2, the two magazines d, d are disposed in V-formation radially to the barrel extension a, which is slidably mounted in the frame b. Each magazine fits into a socket c and is held therein by a lever catch e provided with two teeth e<2>, e', for holding the magazine in the preparatory position and operative position respectively. In the operative position, the lips d' of the magazine enter a slot a' in the barrel extension a and, when the gun is fired, the cartridges are fed from that magazine by a spring d<2>, Fig. 1, with a follower d<3>. A lug d<4> on this follower rides in a slot in the side of the magazine; and when the magazine is empty, this lug deflects the lever catch e thereby releasing the magazine. The lug also deflects a small lever h, Fig. 6, which operates a rod h<0> or h<1>, and thereby rocks a lever h<3>, Fig. 5. Pins h<4> at the end of this lever transmit the rocking displacement to a lever g<4> pivoted at g<5> in an arm g<3> on a spindle g<0>. Another arm g' on this spindle rides in a cam groove in the barrel extension a and is rocked by the reciprocation thereof. When the lever g<4> is displaced as described above, it can reach a lug f<2> on a shaft f<0>, and the rocking movement of the spindle g<0> is thereby transmitted to the shaft f<0>, the ends of which have arms f, f<1> in engagement with lugs d<6>, d', Fig. 4, at the sides of the magazines. The rocking of the arms f, f<1> ejects the empty magazine and raises the other from the preliminary to the operative position, where it is retained by the tooth e<2> of the catch e and retains the arms f, f<1> until these are rocked back when the magazine becomes empty. When both magazines are empty, levers i<0>, i<1> are both free and allow a spring plunger i to rise and lock the breech-block in the open position. In a modification, the shaft g<0> and its accessories are replaced by another shaft coupled to the shaft by toothed segments and clutched when one or the other magazine becomes empty to one or the other of two arms rocked in opposite directions by the recoil of the gun.
