Title: Process and apparatus for the manufacture of hollow bodies
IPC: B28B21/42
Filed: 1949-07-20
Abstract: 673,688. Moulding pipes from concrete &c. SALVANESCHI, P. July 20, 1949' [Aug. 21, 1948], No. 19115/49. Class 87 (ii). Apparatus for the manufacture of hollow bodies, particularly tubes, from pastes capable of hardening comprise a permeable mandrel located within a channel containing the paste, means for rotating the mandrel while providing suction therewithin and means for producing periodic relative motion between the channel and the mandrel to compress the paste on the mandrel, such motion having a component perpendicular to the axis of the mandrel. One end of the mandrel 1 is rotatable in a bearing 3 which can slide in guides in the frame 4. The other end is slidably mounted in a bush 6 which is rotatable in the frame, the end 8 being square and engaging a square hole in the bush, which has a toothed rim meshing with a driving pinion 10. A tube 12 enters the hollow mandrel and is connected to a suction pump. The channel 14 has two ribs 23 mounted on a shaft 26, two eccentrics 25 in phase with each other and both keyed on the shaft 26 engaging holes 24 in the ribs. The shaft 26 is supported by bearings 27 and is rotated by a pulley 28. At the bottom of the ribs an arm 30 is pivoted, on a pin 29 joining the ribs, and its other end is pivoted to a lever 32 fulcrummed at 33. The lever 32 is held in position by a spring 35, adjustment being effected by a bandwheel 37. The paste is poured into the channel and the periodic movement thereof, due to the eccentrics 25, presses the paste on the mandrel, so forming a tube, the thickness of which is adjustable by the bandwheel 37, which governs the distance between the channel 14 and the mandrel 1, variations due, e.g. to excess of paste being compensated for by the spring 35. To remove the tube a ring 21 is released from the end plate 20 and the bearing 3 moved along its guides, e.g. by hydraulic, pneumatic or other means, the mandrel and tube being withdrawn through the hole in the plate 20, after which the tube is stripped from the mandrel by applying pressure to the ring 21. Other means are mentioned for varying the pressure of the paste on the mandrel, e.g. increasing the eccentricity of the eccentrics 25 and moving the bearings 27. The paste may be fed in several lots which may be different, e.g. some' containing fibre, so controlling the quality of the tube, and reinforcement, e.g. metal spiral, may be arranged on the mandrel before applying the paste. The apparatus may be duplicated and mounted on one frame, so that the out-of-balance effects of the moving parts cancel out. Elastic material may be included in the bearing of the pivot pin 29. Pneumatic or hydraulic means may be substituted for the spring 35; or the adjustment may be dispensed with and the pin 31 carried by a lug fixed to the frame. The channel 14 could be guided so that its movement had a component parallel to the axis of the mandrel 1. The apparatus may be used to compress tubes formed on another device, employing the means for varying the pressure of the paste on the mandrel.

Filed: 1952-07-30
Abstract: 719,740. Thread conveying and guiding means. BRITISH THOMSON-HOUSTON CO.. Ltd. July 30, 1952 [July 31, 1951], No 19289/52. Class 120(2) [Also in Group XXI] Containers are filled with filamentary material by entraining the material in a flow of gas towards an opening in the container and diverting the gas as it nears the opening so that the material is carried by inertia into the container. The apparatus used comprises cutting mechanism 2 for slicing metal sheet 3, e.g. aluminium foil, fed by rollers 4, 5 from a roll (not shown) over a bed knife 6 to a co-operating rotatable cutter 7. The rate of feed of foil and the angular velocity of the cutter 7 determine the width of the strips. The feed to the cutters is interrupted at intervals as the desired filling is cut and the sliced material is drawn by a suction nozzle 8 into a feed tube 9 and discharged from its delivery end 10 into a suction head 1 which is connected by tubes 12, 15, traps 13, 14 and solenoid-operated valve 16 to a vacuum pump (not shown). The connection of the pump to the suction head is periodically interrupted by the valve 16 alternately with the connection to a duplicate suction head as in Specification 553,840. [Group XXI]. Supported in the suction head 1 and sealed by a rubber gasket 19 is a bulb 17 into which the strips pass from the feed tube, the end 20 of the tube being spaced from the neck of the bulb. Air is withdrawn laterally from the tube, preferably being reversed in direction, while the momentum of the strips issuing from the tube carries them into the bulb. To prevent air currents within the bulb 17 the suction head is divided into two chambers by a wall 24 through which is a passageway 25 aligned with the tube 9 and having an extension 26 projecting into the bulb. The suction head 1 may be an adapter 35 mounted on the apparatus described in Specification 553,840. In modifications the suction head is singlechambered, the air flow being led off through parts in the suction head. Specification 540,846, [Group XXI], also is referred to.

Title: An improved method of and means for weighing objects
IPC: G01G13/00
Filed: 1934-06-30
Abstract: 430,861. Weighing-apparatus. AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD, 20, Alstr÷mergatan, Stockholm. June 30, 1934, No. 19374. Convention date, July 1, 1933. [Class 143] In a method of progressively weighing objects which are alternately supplied to the same weighing-member each object is brought into position above the weighing member whilst a preceding object is being weighed thereon, and thereafter by means of a carrier is automatically lowered on to the weighing member when the weighing of the preceding object has been finished. As shown, bags of flour 5 are carried step by step, upon a partitioned conveyer 4, to two cam-operated pushers 1, 2 which alternately push a bag off the conveyer and on to an adjacent carrier 20 or 21. The carriers are alternately reciprocated in a vertical direction by cams and are grid-like in form so that in their lower positions they mesh without contact with corresponding openings in the scale pan 17 and leave the bag on the pan for a weighing operation. In the highest positions of the carriers (the bag-receiving positions) the bags are clear of the scale pan. The bags are thus alternately transferred from the conveyer 4 to the scale pan and as one bag is being raised from the pan by one carrier after weighing, another bag is being lowered by the other carrier for weighing thereby avoiding idle periods in the use of the weighing scale. Pivoted walls 31 actuated by cams on the carrier rods guide the bags but swing outwardly to leave the bags free when the carriers descend. As new bags are pushed on to the carriers the weighed bags are pushed off thereby, the transfer to a conveyer 37 being completed by a cam-operated plate 40 moving in an horizontal direction. In a modification, the pushers 1, 2 are replaced by intermittently-advancing conveyers running above the carriers and provided with pinchers for gripping the bags. The bags may rest upon loose plates during the various operations to avoid wearing the bottoms of the bags.

Abstract: 478,206. Sewing-machines. EBERT, F., and MAUSER-WERKE AKT.-GES. July 13, 1936, No. 19407. [Class 112] In a multi-needle machine for covering seams, a finger for holding up the needle threads in the descent of the needles is provided so that chained stitches are formed between the successive pieces of fabric operated upon, the finger being attached to the presser foot. The invention is shown as applied to a machine with three needles 1, each with its own thread, and one threaded looper 3. The needle threads 5 are held close to the needles on their descent, Fig. 9, by a finger 7, while the looper 3 is engaging the previous loops. The looper withdraws from these loops, and the needles continue to descend, the finger 7 being withdrawn. The looper can then enter the loops 8, Fig. 10. The finger 7 is mounted in a socket 25 on an arm 10 pivoting on the presser bar 9 and driven from the looper actuating rock-shaft 12 by the connections 11, 14, 15, 17, 20. The amplitude of the finger swings is determined by the position of the stud 19 in the slot 18, Fig. 1. The effective length of the rod 20 is adjustable in the screw-socket 10 and the finger may be adjusted for needles of different thicknesses by mounting the arm 10 on an eccentric sleeve 23 on the presser bar. The finger fits into a recess 28 in the presser and is lifted and lowered therewith. The four-thread seam formed is shown in Figs. 9 and 10.

Abstract: 147,635. Wilcox Machine Co., (Assignees of Wilcox, A. C.). March 6, 1917, [Convention date]. Blowing; pressing; removing articles from moulds; shearing.-Relates to a three-unit automatic machine for blowing bottles, also applicable to press-moulding. The moulds, shears, &c. of each unit are operated by pneumatic cylinders B - - Z, which receive air through valves C<1> - - J<1> controlled by rotating cams C<2> - - J<2>. The parison mould 52 is charged by hand through a funnel 35, and the gatherer trips a valve lever with his iron. This admits air to the cylinder B, which operates the shear blade 47, and also to a cylinder 145 which operates a clutch on the cam shaft T and causes it to make one revolution. The slide 34 carrying the blowhead 36 is drawn back by a piston 50 so as to bring the blow head into position for compressing the charge in the parison mould. The neck rod 54 is raised by a piston 55 and then lowered to admit air for the preliminary blowing in the parison mould. When the parison mould has been opened, the ring mould 79, which is mounted on the end of a piston rod 73, is then drawn to the left, so as to bring the blank over the finishing mould 65, and the piston rod 73 is rotated by a rack mechanism 78, so as to swing the blank down into the finishing mould 65, which is then closed and the blowing completed by a head 98. The finishing-mould 65 is next opened and the cylinder G is raised slightly by a piston 88, so as to lift the blank clear of the finishing mould bottom. A further movement to the left brings the finished bottle over a tube 101 down which it slides into a conveyer 109 when the ring mould 79 is opened automatically by the impact of spring rods 82 against a plate 74.
