Abstract
809,414. Filters. SUNBEAM CORPORATION. Aug. 2, 1955, No. 22170/55. Class 46. [Also in Group VI] A filter, for use in a coffee maker, (see Group VI) comprises a screen with a frame having a rim of resilient material moulded onto the screen and provided with an outwardly angularly-extending web portion moulded integrally therewith which forms a sealing engagement inside the vessel of the coffee maker. As shown, Figs. 2 and 4, the filter 20 comprises a screen 21, e.g. formed by electro-deposition or woven from drawn stainless steel wire, supported by a frame 22, with a hub portion 23, tapering spokes 24 and rim 26. The edges 29 of screen 21 are received in the groove of a screen-retaining member 32 which engages in the inner edge of rim 26, Fig. 4. The rim 26 has a resilient web portion 37 connecting its inner edge portion 25 to a bead portion 36 which engages the vessel 11, Fig. 1. Projections 38 on frame 22 engage wall 12 of the vessel to locate the filter in the vessel. In Fig. 7 (not shown), a rim 41 may be moulded directly on to the edge of a screen 43, the remainder of the construction being the same as before. A metal frame 61 may be used, Fig. 11, which supports a screen 65, a rim 67 being moulded thereon. Specification 672,450 is referred to.
