Filed: 1927-02-12
Abstract: 290,365. Jackson, L. Mellersh-, (United States Cast Iron Pipe & Foundry Co.). Feb. 12, 1927. Annealing-furnaces; charges, conveying.-In a furnace for annealing cast iron pipes, of the kind in which the pipes H are supported in and carried through the furnace A by a series of overlapping rotating rollers F - - F<23> having notches G in their peripheries, the latter have crests G<1>, G<2> at each end to prevent the pipes from passing from one set of rollers to the next with accelerated speed and are formed with the concave portion G<3>, Fig. 7, of greater radius of curvature than that of the circumference of the pipes H, this construction ensuring that the pipes will roll on the surfaces G<3> and thus be continually rotated as they pass through the furnace. The notches in successive sets of rollers are disposed at progressively different angles so that the pipes will be lifted at different times and the strain on the driving- mechanism of raising all the pipes at once avoided. The rollers F - - F<23> are mounted on shafts E carrying worm wheels E<1> which engage with a series of worms D<1> on a driven shaft D extending longitudinally through a wheeled carriage C which supports the whole conveyer mechanism.

Title: Moulded pulp wads and apparatus for moulding such wads
Inventor: RANDALL WALTER HALL
IPC: F42B7/08
Filed: 1953-02-16
Abstract: 725,437. Ammunition cartridges. KEYES FIBRE CO. Feb. 16, 1953, No. 4296/53. Class 9(1). [Also in Group V] A wad for shot-gun cartridges is felted in cup-shape and the upper portion is then folded inwards so that a felted layer extends completely around the wad. To form the wads a pair of dies is used of which the female die comprises a stationary imperforate cylinder 48 enclosing and spaced from a stationary sleeve 45 with drainage perforations 46. Slidable in the sleeve is a tubular member 16 having a perforated upper closure 53. This member constitutes the bottom of the die during formation of the wad and is afterwards used to push the wad out of the mould. The male die member 54 consists of a slidable tube with a perforated base. Fibrous pulp slurry is supplied to the dies by a vertically reciprocating tank 21 and water drains from the pulp through perforations 46 into an annular chamber 47 and thence through passages 49 in a platen 42 to a chamber 50. From the chamber 50, it passes through an opening 51 into the member 16. Air may be evacuated from or supplied to the members 16, 54 as required. As the completed wads are pushed out of the dies they are received by a transfer unit 64, Fig. 6, carrying a perforated plate 65 defining a chamber 67 which can be connected to a vacuum pump or a pressure pump at 68. The unit 64 is mounted on rollers 69 for horizontal reciprocation by a motor (not shown). The tank 21 is first raised to submerge, in the slurry, the die member 45 which is connected to a vacuum pump draining liquid from the die. When a sufficient thickness lines the die member 45, the tank is lowered and the plunger 54 is moved to compress the wad. Compressed air may be forced through the plunger 54 to further the removal of water from the wad. The plunger 54 is then retracted and the slidable member 16 moved upwards to carry the wad out of the sleeve 45, whereupon the unit 64 moves over the wad. The suction from the member 16 is stopped and suction is applied to the plate 67 to transfer the wad 15 from the member 16 to the under-surface of the plate 67. The member 16 is then retracted to recommence the cycle of operations. The wad held by the transfer unit is carried to a conveyer belt, the suction stopped and the wad drops on to the bolt. Compressed air may be forced through the plate 67 to facilitate release of the wad. The wads may be made from ground wood pulp and sulphite, soda or kraft pulp. The finished wad may be waxed and after drying is placed over the powder charge in a cartridge. A machine is shown in Figs. 7 and 8 provided with a gang of plungers 114 registering with dies 76 in a tank 81, each of the elements 114, 76 and 81 being operated by a hydraulic ram. A transfer unit 124 is actuated by a motor-driven feed screw 134. Timing mechanism (not shown) is provided for controlling the sequence of operations. The unit 124 transfers the finished wads to a conveyer belt 137 which may pass through a dryer (not shown).
