Title: Improvements in or relating to boxes for the packing and transit of fruit and other soft produce
IPC: B65D6/34
Filed: 1948-04-20
Abstract: 638,544. Boxes. VARNEY, J. W. April 20, 1948, Nos. 10868/48 and 9749/49. [Class 18] A box has upstanding corner elements for supporting boxes stacked on top and for providing air space, the corner elements passing through holes 7 in a flanged lid 8. The elements 3 may form part of a separate unit in which case they are carried on a spring frame 1 which enables them to be engaged round the corners of the box. The elements 3 may have pressed out tongues which engage the box and/or lid to prevent their displacement. In alternative forms, triangular section hollow elements may be formed integral with the box walls, as shown at 11, or may be wholly or in part formed of separate sections secured within the box. Filling pieces may be inserted in the hollow elements and bands may encircle them, pressed out tongues on the bands engaging the elements and preventing the lid from rising. The holes 7 assist in ventilating the box.

Abstract: 119,650. Beck, F. C. Aug. 2, 1917, [Convention date]. Limbs, artificial.-In limbs having a number of actuating-members, these are selected and operated by a member connected to the source oi power. A hand having jointed fingers and thumb, as shown, is opened against the ::ction of springs 33 by a cord 18 engaging a pulley 16 on an arm 15 pivoted to a toothed sector 12 mounted on a spindle 5. This sector is operated by a cord 1 through the selecting and operating member 2 which is pivoted to an arm 6 loosely pivoted on the spindle 5. A second cord 9 is operated to bring the member 2 into engagement with the toothed sector 12 or with a toothed lever 19, 20 which also is mounted on the spindle 5. The arm 20 of the toothed lever operates an arm 210 connected to a hinged member 22 and adapted to increase the grip on the article held by slackening the cord 18.

Abstract: 591,193. Building frameworks. BURGESS, G. N. May 1, 1945, No. 11037. [Class 20 (iv)] A vertical member for use in building structures, which are formed of a framework of vertical and horizontal members, has a longitudinally extending channel, the side faces of which are provided with laterally extending projections arranged to support elements associated with the horizontal members. As shown the channel 11 in the vertical member 10 is formed with zig-zag faces 12. The end of the horizontal member 13 may be correspondingly shaped to fit into the channel or as shown a U-shaped bracket element has each limb 21 folded outwardly and shaped to form a zig-zag section 20 corresponding to the channel faces, the horizontal member 13 being supported in the U of the bracket. The bracket may be supported by a block or corbel formed with zig-zag projections and engaging in the channel 11 directly beneath the bracket. The corbel member may be used alone without any bracket, the member 13 resting directly upon it. Holes are formed in the side walls of this channel 11, in the bracket elements and in the horizontal members with pins 19 passing therethrough. The holes in the supporting element and horizontal member are arranged so that the height of the horizontal member may be varied by reversing the horizontal member or supporting element. Preferably the vertical and horizontal members are formed of reinforced concrete, the horizontal members being of I or Tee-section along most of their length apart from the integral supporting element. The channel 11 may be provided with curved surfaces on its inside faces and where a bracket is employed it is formed with a bowed outer limb conforming to the curve.

Convention date, April 28, 1930. [Class 80 (ii).] In cone friction clutches, for example, for reverse clutches of automatic lathes, and comprising a member provided with a chain driving wheel and the hollow cone, and running on a roller bearing, a ball bearing for taking the end thrust is arranged adjacent the roller bearing at a position where the dimensions are not limited by the diameter of the chain wheel which must be kept small to obtain a high speed of rotation. The use of end pressure discs is thus avoided. The cone a which drives the lathe spindle b through the displaceable cone c is carried by the cylindrical member e and is driven by the pin f. The member e is formed with the chain wheel r and runs on the roller bearing s and the ball bearing t which is disposed in the plane of the cone a and takes the end thrust. Adjustment of the cone a is obtained by turning the ring i which has oppositely screw-threaded engagement with the member e and cone a. The ring i is locked by a spring plunger q sliding in a radial bore in the member e and carrying a pin for engagement with teeth m on the ring i. Centrifugal force assists to hold the locking-pin in engagement.
