Abstract: 574,541. Chain and belt gearing ; toothed gearing. NORTHERN PATENT DEVELOPMENTS, Ltd., and BARTLETT, B. G. W. Aug. 12, 1943, No. 6501/45. Divided out of 574,399. [Class 80 (i)] [Also in Group XXXI] In belt or chain drives incorporating a driven shrouded toothed pinion meshing with a shrouded internal toothed gear of an annular floating gear ring, means are provided for adjusting and maintaining the tension of the driving belt or chain. As applied to the chain drive of a velocipede, a chain 17 connects the driving wheel 11 with a floating annular gear ring 14, the internal teeth 15 of which mesh with the teeth of a pinion 12 on a hub on the spindle 13. A bracket 29 rigidly secured on the spindle 13 has pivotally mounted thereon at 31 an arm 30 carrying an idler sprocket 32 which engages the return run 26 of the driving .chain against which it is urged by a spring 33. When a drive is being transmitted, the floating ring 14 dips, by rolling on the shrouds of the. teeth, so as to bring the parts into the positions shown by broken lines, the ring 14 then being so disposed that the angle between the lines 27, 13 and 13, 28 is approximately 130 degrees, the point 27 being the point of contact between the floating ring and the pinion.

A mould for producing articles from concrete, cement or plaster comprises one or more outer ports of a resilient material and a core part, said parts being capable of assembly mutually to define a mould cavity having water-impermeable surfaces. The resilient material is preferably mounted on reinforcing structures which attach together to define a mould cavity, and the resilient material may be shaped to produce a pattern resembling brickwork on the moulding. The mould shown in Fig. 3 for casting a truncated pyramidal concrete tub comprises hard rubber core mounted on a wodden base 16. The mould comprises two pairs of sides 11, 12 on which are mounted symmetrical resilient rubber trapezoids 13 with a raised brick pattern. The mould sides are hinged to the base at 15 and when in the closed position can be fixed together by bolts 20. The interior of the mould is lined with the resilient rubber layers 13 and 17 which together define a waterproof cavity and which, due to the flexibility of the rubber can be easily removed from the moulded article. Selected cavities in the rubber lining can be filled with a pigmented cement preparation before casting. In an alternative embodiment, the core 23 is formed as a single unit with a hard rubber base 25 and the mould walls are formed in one section 22 from a softer rubber. This section has a wavy slit 28 extending down one face and a groove 29 on each side thereof. The section 22 is shaped to engage a groove formed in the underside of the base 25 and is held closed by a U-shaped channel member engaging the two slits 29. The moulds and mould linings may be made of rubber or any synthetic materiol with suitable properties.
