Abstract: 723,411. Lifting jacks ; load handling machines. BASHFORD, J. A. March 28, 1951 [Dec. 28, 1949], No. 33110/49. Class 78(3). A column 5 carrying load-engaging members 13, 8, is guided on a fixed pillar 1 by sleeves 7 and is moved therealong by operation of gripper rings 16; 17, which are pivoted to the column and which alternately engage the pillar when the handle 24 is oscillated. Gripper 17 is pivoted at 23 to an extension 20 of lever 24 which is pivoted at 22 to a link 19 pivoted to the column 5 at 21; and the lower gripper 16 is pivoted at 18 to column 5. Springs 26, 27 are provided to retain the grippers in engagement with the pillar. When it is desired to raise the column, handle 24 is moved downwardly and the gripper 16 slides upwardly until it reaches a projection 32 on gripper 17, whereafter the handle is raised to move the gripper 17 upwardly by a corresponding amount. To effect lowering the handle 24 is moved upwardly until, due to the engagement of an abutment 31 and a projection 33 on the gripper 17, this gripper is freed from the pillar whereupon a pawl 34 engages a catch on projection 32; the handle is now lowered and the gripper 17 slides down the pillar until an extension 35 of the pawl 34 abuts against gripper 16, so releasing the pawl from the catch and allowing the gripper 17 to reengage the pillar. Further downward movement of the handle moves the gripper 16 up the pillar until the projection 32 presses it into a horizontal position where it is held by the engagement of a catch 38 thereon with a pawl 36. Upward movement of handle 24 now allows the column 5 to lower until an arm 41 on pawl 36 engages a collar 40 so releasing this pawl and re-engaging the gripper 16 with the pillar. Rapid adjustment of the column 5 is effected manually after releasing the gripper 17 with handle 24 and releasing the gripper 16 by moving a handle 42 thereon downwardly; a handle 43 rigid with the lower sleeve 7 facilitates this adjustment. In various modifications (not shown) a device for handling barrels, comprising a pair of chains suspended from the ends of a horizontal bar, is secured to member 8; or a sack holding frame is attached to member 8 and the upper extension of column 5; or a jib member is secured to the top of column 5 and supports a load handling chain at its free end. The device can also be used as a roof prop or for holding shuttering in place. The pillar 1 is supported on four rods arranged radially in a multiple socket which also houses the base of this pillar.

Filed: 1933-11-27
Abstract: A sheet of paint having a larger proportion of oil, e.g linseed oil, than is usual in paints, is provided with a non-textile backing to form thick pliable sheet-material which is easily cut.  A composition prepared by grinding pigment in linseed oil and adding a mixture of turpentine with resin dissolved in boiled oil is applied by spraying to a smooth sheet of glass, glue is applied to the composition when set, and a temporary fabric support is attached to the glue by means of adhesive.  The compound material is then stripped off the glass, after which the fabric is removed; the material may finally be strengthened by applying thin celluloid.  A rough surface may be used instead of smooth glass, in which case a priming-coat is applied first, the backing next, and the paint last.  In an alternative process, a temporary fabric-support is laid on a sheet of glass, glue is applied to the fabric, and the paint is applied to the glue, the material being stripped off and the fabric removed as before.  The material may be used for covering metal, wood, &c., and decorative or other display matter may be painted on the material.  By applying the composition to a shaped surface, a moulded effect may be produced.
