Filed: 1936-06-08
Abstract: 476,438. Foot-arch supports. DEHN, F. B. (Hood Rubber Co., Inc.) June 8, 1936, No. 16032. [Class 17 (ii)] A combined sole and arch support consists of a sole having a raised resilient portion 11 on the inside edge, bounded by the line 12 and the reversed curve 14, and a heel portion 18 of harder material, either the resilient portion or the heel portion being formed integrally with the sole. The thickness of the sole in the raised part decreases towards the opposite edge and reaches the normal thickness of the sole along the line 12. Along the line 14, the thickness of the raised portion changes abruptly to the normal thickness of the sole leaving a ridge, the height of which tapers to nothing at the point 17. The raised portion may be integral with a resilient sole, in which case a heel piece 18, Fig. 5, of harder material, of a thickness slightly less than the height of the ridge at 14 and tapering in thickness away from the outside edge is adhesively secured to the sole so as to abut coincidently against the ridge. Alternatively, the heel piece may be made integral with a sole of hard material and the arch support 43, Fig. 1, of more resilient material applied to the sole. Preferably, the point of greatest difference in the heights of the resilient and heel portions occurs at the intersection 15 of the reversely curved edge with the inner border of the sole. The arch support in both the modifications previously described may be formed on a separate sole, as shown in Fig. 5, or on a solid sole, as shown in Fig. 17.

Title: Method of making a cushioning unit
IPC: B61G9/06
Filed: 1956-05-24
Abstract: 797,164. Rubber compression springs. NATIONAL MALLEABLE & STEEL CASTINGS CO. May 24, 1956 [June 6, 1955], No. 16081/56. Drawings to Specification. Class 108(3) A method of making a cushioning unit having a capacity and a size within predetermined tolerances, from a group of resilient pads of rubber-like material, comprises the steps of grouping an established number of the pads, subjecting them to a predetermined compressive force to induce a permanent set in the resilient material of the pads, releasing the force, determining the capacity and size of the unit, and in the event that the capacity or size is above or below the predetermined tolerances, substituting one or more pads of a different thickness or hardness, as necessary, to bring the capacity and size within the predetermined tolerances. The force may be applied as a single force of about 85 per cent of the design load for the pads of the unit at the latter's maximum rated travel. Alternatively the force may be applied in the form of three to five successive loads in fairly rapid order, each being about one-half of the design load for the pads. The unit is then allowed to set for a period of from 48 to 72 hrs. The capacity and size of the unit is determined by either recompressing the unit to a given overall length and measuring the load required, or by recompressing the unit by a given force and measuring the height of the unit under this force. The pads may be of the construction described in Specification 686,211. Where it is necessary to substitute fresh pads in order to adjust the capacity and size of the unit, the added pads should previously have been subjected to a compressive force to take up permanent set. While the unit is under the set-inducing force the edges of the pads are inspected for any defects which may occur. The pads should be removed from the rubber curing moulds for at least 24 hours before the set-inducing force is applied.
