Abstract: 934,896. Boots &c. TRIMFOOT CO. May 1, 1961, No. 15690/61. Classes 17 (1) and 17 (2). A shoe has an outsole and insole, a counter, and a reinforcement member for the counter and secured to the counter along part of an inverted arcuate line so as to form a downwardly open pocket to receive a counter stiffener whose lower marginal edge portion is free of attachment to the soles. The reinforcement member can be inside or outside the counter. The reinforcement member 13 (Fig. 1) for a child's boot includes a top band portion 14 and optionally an interconnecting portion 15. The quarter is first stitched to the band 14 along the line 17, and then, after moistening or mulling, the two members are put between heated moulds (Fig. 3, not shown), the upright centre section of which is the shape of an ogee curve. Side facings 20 are now stitched to the quarter and the member 13 stitched to the quarter along line 18 forming the pocket for the counter stiffener which is now inserted. When the rear quarter unit is applied to the last, tabs 24, 27 on the inner member are turned in over, and cemented to, the insole while the lower margin of the outer member is wiped outwardly and the outsole and welt attached by stitching or cement. The above mulling and shaping step may be replaced by cutting and shaping the quarter and reinforcement member in two parts and stitching the parts together to form a vertical seam at the back of the shoe. The Oxford type low quarter shoe is formed in this way with the counter stiffener pocket extending to the top of the shoe.

Abstract: 1,163,824. Rear axle suspensions. FORD MOTOR CO. Ltd. 7 April, 1967, No. 16062/67. Heading B7D. In a motor vehicle suspension comprising generally longitudinally extending leaf springs 9 which support the sprung mass of the vehicle on a rigid rear axle 1, eyes 13 at the front ends of the springs are connected to the sprung mass through rubber bushes and further connecting means between the springs and the sprung mass is arranged such that the sprung mass exerts on each spring a force acting towards the front end of each spring. The front portions of the bushes are thereby relieved of load and the bushes are better able to absorb noise, vibration and harshness. Rubber elements 21 bonded between brackets 17, 19 attached to the sprung mass and to the springs 9 permit rearward movement of the rear end of each spring under load and exert a forwardly-acting force on each spring. An extension 27 of the differential casing 3 is connected to the sprung mass by rubber bushes 29 arranged such that the axle 1 exerts a forward force on the springs 9 through links 23 which are secured to the axle and pivotally connected through rubber bushes to plates 25 on the springs. The springs 9 converge rearwardly and the rubber elements 21 permit limited lateral movement of the rear ends of the springs so that lateral movement of the axle 1 under cornering forces produces rear wheel understeer. Shock absorbers 7 are connected between the sprung mass and the springs, and rubber blocks 31 mounted on the sprung mass engage the springs to provide a variable rate suspension.
