Title: Clip for pivotally connecting a rod-like member to an apertured support
IPC: F16B9/02
Filed: 1964-05-20
Abstract: 1,043,304. Cotters. UNITED CARR Inc. May 20, 1964 [June 4, 1963], No. 20855/64. Heading F2H. [Also in Division E2] A clip for pivotally securing a rod-like member 3 to an apertured support 1 comprises a pair of opposed arms 6, 7 respectively positionable over opposite faces of the support, each arm having an aperture 9, 10 alignable with the aperture 2 in the support and the arm 7 having a spring finger 11 adapted resiliently to engage part of the member 3 when it is inserted through the aligned apertures 9, 2 and 10, to secure the rod-like member in assembly with the support. As shown, the rod-like member has a cranked end 5 which is inserted in the apertures 9, 2 and 10, and a portion which is held by the spring finger 11 in an aperture in a portion 8 of the clip connecting the arms 6, 7. The portion 8 has notches at its ends adapted to receive the edge portions of the support 1 to permit greater relative rotation of the members 1 and 3, and the portion 8 and arm 7 are strengthened by a bead 15.

Title: Improvements in and relating to slug casting machines
IPC: B41B11/38
Filed: 1936-07-29
Abstract: 479,040. Type-bar-making machines. CLEMO, F. A. (Mergenthaler Linotype Co.) July 29, 1936, No. 20976. [Class 100 (iii)] In a type-bar-making machine, adjustable devices mounted on the justifying devices are adapted to coact with a fixed part of the machine in order to limit the movement of the justifying-devices during justification. Mechanism for adjusting the limiting devices automatically in accordance with the point size of the slug to be cast may be provided. On the two vertical rods A<1>, A<2>, Fig. 1, carrying the justification bar A is adjustably mounted a cross-head B carrying adjustable set screws b<1> adapted to coact with the fixed part C of the machine frame to limit the upward movement of the cross-head and therefore of the rods A<1>, A<2>, and bar A. Toothed blocks B<4>, B<5>, Fig. 3, slidably mounted in the cross-head B engage racks A<3>, A4 respectively, on the rods A<1>, A<2> to secure the cross-head in any required position of adjustment on the rods, the blocks being connected by links B<7>, B<8> and a lever B<6> for simultaneous movement to release or lock the cross-head B. A spring-pressed pin B<11> engages the lever B<6> to bias it towards the locking position. The block B<5> is capable of limited vertical movement in the cross-head B and relatively to the end of the link B<8> against the action of a spring b<4> to permit of the usual differential movement beteween the rods A<1>, A<2> during the initial part of the justification operation. To release the blocks B<4>, B<5>, a handle G pivoted at G<1> is operated, an extension G<2> actuating a sliding bolt F to turn a cam member engaging the end of an arm D fixed to the block B<4>. Another handle G<3> also pivoted at G<1> has an extension G<4> bifurcated to engage a pin B<14> on the cross-head B, whereby the cross-head can be moved along the rods A<1>, A<2> A pointer G<2> integral with the lever G<3> moves over a scale H to indicate the position of the cross-head B. A stop limits the upward movement of the extension G<4> so that a minimum amount of space-band expansion is always provided for. The release and adjustment mechanism of the cross-head may be coupled to the mechanism for adjusting the right-hand trimming knife, so that the amount of justification varies with the point size of the slug to be cast but is independent of its length. Tor this purpose, when the knob J<3> attached to the disc carrying the knife-adjusting studs is withdrawn for effecting adjustment, a collar J<4> thereon moves a lever K<1> attached to a rod K<3> adapted to move the. bolt F to release the blocks B<4>, B<5>, from the rods A<1>, A<2>. A stud K<6> projecting from the knife block J engages a lever K<8> pivoted by means of a pin K<10> to an extension G<6> of the adjusting-lever G<3> so that adjustment of the knife block by means of the knob J<3> causes a corresponding movement of the cross-head B. By withdrawing the pin K<10> and the pivot pin of the lever K<1> the automatic adjustment of the cross-head can be cut out.

Title: Improvements in jute yarns and fabrics
IPC: D01C1/02
Filed: 1953-07-30
Abstract: Jute fibres are treated prior to carding with water and with about 4 to 9 per cent (by weight of the dry fibres) of a composition comprising a light petroleum oil and a drying substance dissolved therein in such an amount that the composition will remain liquid during the textile operations and will set subsequently to a solid or plastic condition.  The composition is of use in the preparation of jute backing material for pile fabrics, in which case the mineral oil is prevented from migrating to the pile, which may be of cellulose acetate, regenerated cellulose, bleached jute or cotton fibres.  The water may be applied prior to the application of the oil composition and may contain a wetting agent or the oil may be applied in aqueous emulsion.  The oil may be cordage oil or a naphthenic base oil and the drying component may be a vegetable oil acid or an unsaturated, partly aromatic, partly aliphatic petroleum fraction, and may contain an evaporable solvent and a metallic soap drier.  In examples, the drying component comprises (3) a tall oil product comprising rosin acids, saturated acids, oleic acid and linolenic acid, together with lime; (4) a highly unsaturated rosin, lead and manganese naphthenates and solvent naphtha; (5) naphthenic acid, heat-bodied linseed oil, lead and cobalt naphthenates and a volatile solvent.ALSO:A lubricating composition for application to jute fibres during spinning comprises a light petroleum oil, such as cordage oil or a naphthenic base oil, and a drying substance dissolved therein in an amount such that the composition will remain liquid throughout the textile operations and will subsequently set to a plastic or solid condition.

Abstract: 460,251. Stringed musical instruments ; organs. ALLWOOD, J. H., MASON, B., and FREESTON, H. A. July 25, 1935, No 21184. [Class 88 (ii)] A musical instrument of the guitar type, is provided with a keyboard 8, for stopping the one or more strings 4, which are strummed bv hand or with a plectrum, some of the keys being outwardly cranked at their rear ends to reduce the length of the keyboard, and a felt or other damper 14 is provided and is adapted to be pressed away from the strings when the end-key 8c, adjacent the nut, is depressed for use in sounding an open string. A reed-organ, operated by the same keyboard may be combined with the guitar. The keyboard is of the piano type, with black and white keys giving whole- and semi-tones. The keys 8 are carried by blade return-springs 10, Fig. 4, secured to a bar 9, hinged to the neck 1 of the instrument, so that the keyboard can be pivoted away to expose the strings. Downward movement of the keys is limited by a bar 15, and upward by a pad 16, the keys having -ribs 11, Fig. 6, for engaging the strings, which latter are tuned all in unison or an octave apart.

Abstract: 443,209. Testing the balance of sports implements. MURDOCH, A. G., 19, Amner Road, Battersea, London. July 20, 1934, No. 21278. [Class 97 (iii)] A device for testing the balance of golf clubs, rackets or other sports implements comprises a pivoted support for the handle of the implement adapted to hold the implement in a substantially horizontal position and having stop means to position the extremity of the handle in alignment with the pivoting axis of the support and means for balancing the turning moment applied to the support by the implement. As shown in Fig. 1, a golf club handle g is placed in a hollow arm of a weighing beam 4 so that the end of the handle abuts against a cross pin situated in line with the fulcrum knife-edge 8. A poise weight 10 is then adjusted to bring the beam into balance. The graduations on the beam then indicate the nature of the properties to be estimated. In a modification, Fig. 5, the device is self-indicating, the socket 17 for receiving the implement being connected by a lever system to a pendulous lever 26 coupled by a link 34 to an indicating pointer 11. The device is provided with levelling screws and with a spirit level or with a pendulous lever actuating a level-indicating pointer. According to the Provisional Specification, the implements may be tested by an impact method wherein the implement receives a blow from a pendulum-like device released from a set position.
