Title: An improvements in a fabric laying up machine
IPC: B65H45/103
Filed: 1962-02-06
Abstract: 948,414. Layering fabric. TOWLES Ltd., R. F. L. THURMAN, and L. G. ROCKINGHAM. Dec. 4, 1962 [Feb. 6, 1962], No. 4564/62. Heading D1S. A fabric laying-up machine of the kind comprising a table 1, a carriage 4 for supporting a supply of fabric, a pair of feed or laying up rollers 5, 6, on the carriage, reversible drive means for causing the carriage to travel back and forth over the table whereby fabric is laid in zig-zag folded fashion, a vertically movable mounting on the carriage for the feed rollers 5, 6, and a mechanism, including ratchet gearing, which is automatically operable in timed relation with the back and forth movements of the carriage for intermittently raising said mounting to compensate for the growing height of the pile of layers of fabric, in characterized in that the table 1 has a centrally longitudinally extending main portion 1a the surface 1b of which nearly touches the undersides of the feed rollers 5, 6, when the latter are in their lowest positions and in that the marginal portion 1c of the table, which portions carry the tracks for the carriage, are set down relatively to the central main portion. Preferably the space between the table surface 1b and the rollers 5, 6, corresponds to the thickness of the fabric to be laid. As shown the invention is applied to a machine for laying tubular fabric F which passes over a stretcher 9 so that the fabric is stretched and spread in a plane at right angles to that in which it is drawn from the supply and is thus laid so that the creases or folds F<1> initially extending along the longitudinal edges of the tube F are caused to extend coincidentally along the median line thereof. An existing machine can be modified by securing a skeleton framework to the table to build the central portion up to the required height. The framework may be covered with hardboard, rough side up, to present a slip resisting surface. Specification 805,477 is referred to.

Title: Improvements in operating mechanism for retractable members on board aircraft
IPC: B64C25/24
Filed: 1937-02-18
Abstract: 495,759. Springs; shock-absorbers. AIR-EQUIPEMENT. Feb. 18, 1937, Nos. 4872 and 4873. Convention dates, Feb. 18, 1936 and Aug. 12, 1936. [Class 108 (iii)] [Also in Groups XXXIII and XXIV] A motor unit disposed at the hinge of a folding strut used to retract an aircraft under carriage includes a damping device comprising a cylinder 120 secured to housing 15 and to element 5. A double vane 121 works in cylinder 120 and is connected to element 4 by a lever 123. A second double vane 124 is displaceable between stops 125, 126 formed by the edges of recessed parts of cylinder 120. The blades of vane 124 extend to the full diameter of the recessed portions but are provided on one face with a flange of the same diameter as the cylinder bore. Radial holes 127 in the hub of vane 121 place the four compartments of the cylinder in communication with a central bore 128 in hub extension 122 containing an adjustable piston valve. Valves 130 in blades of double vane 124 operate only in the direction f <1> ; these ensure that the movement of vane 121 is undamped during retraction. During extension damping only takes place when vane 124 moves round to the ends of the recessed parts of the cylinder, and ceases when the blades of vane 121 themselves reach the recessed portions except that the action of the flange formed on the faces of vane 124 is to damp the impact of the vane with the stop 126. The elements 4 are interconnected by a bracing tube 130 in which is housed a torsion rod 140, Fig. 10, connected to one element 4 at one end and carrying a lever 142 at the other, coupled by a link 145 to a pin 146 on one element 5. Pin 146 is offset from the hinge axis and the angular disposition of lever and link are that as the strut folds, the torsion rod is first twisted and then untwists assisting retraction in the second stage, whilst on extension the rod first opposes and next assists extension of the strut. Specification 442,133, [Group XXXIII], is referred to.

Title: Improvements in and relating to tools for firing pins, nails, rivets and the like into bodies
IPC: B25C1/12
Filed: 1955-02-18
Abstract: 790,554. Cartridge-operated tools for firing pins &c. SCHULZ, W. Feb. 18, 1955 [Feb. 23, 1954; March 13, 1954], No. 4964/55. Class 119 Relates to a cartridge-operated tool for firing pins &c. of the kind having a barrel mounted within a casing for rearward displacement against spring resistance relative to a body portion for holding the tool and incorporating a firing mechanism with a trigger or like release. According to the invention the barrel must be displaced rearwardly to a certain point before the firing mechanism is effective but on firing the barrel can recoil to a more retracted position. In one form Fig. 1 on pressing the tool against a wall, the barrel 1 and breech block 2 are moved rearwardly within the body portion 7, the release element 10 housed within the breech block 2 moving the striker 5 rearwardly by engagement of its step 13 with a shoulder 12 of the striker. This rearward movement is limited by engagement of the rear end 21 .of the striker with the rear end of the body portion 7. In this position the striker, if released, can reach the cartridge. On operating the trigger 16 the release element 10 is moved upwardly, releasing' the striker from the edge 13, permitting the striker to move forward and fire the cartridge and the breech block and barrel to recoil rearwardly. In another form, Fig. 2 the firing position of the barrel is determined by engagement of the barrel casing with the surface against which it is pressed. In this position the protective shield 28 formed at one end of the casing 19 engages the surface and although the striker is moved rearwardly it does not engage the rear end of the body portion 7, but is effective on release to strike the cartridge. On f@iring the breech block and barrel can recoil rearwardly from this position. In another form, Fig. 3 (not shown) instead of the barrel casing, a guide tube 33 engages the surface and determines the firing position, or the tube may be replaced by a rod connected to the tool 'body.
