Abstract

1,171,944. Advancing mine roof supports. K. M. GROETSCHEL. 30 Nov., 1966 [30 Nov., 1965; 16 Nov., 1966], No. 53519/66. Addition to 1,133,099. Heading E1P. In an advancing mine roof support comprising an inner unit B disposed in and movable along a slot in the base 30 of an outer unit A, the base of the unit A has side portions 31, 31', interconnected at opposite ends by members 32, 33 and supports one part of the superstructure by props 35, 37 whilst the unit A includes props 53, 55 which support a further part of the superstructure and are interconnected by a strut or distance-piece. The support is also provided with a shield 33, a stabilising device 108-111, steering means, roof extension pieces and various minor modifications and additions for details of which the Specification and Figs. 1, 2, 3 and 8, (not shown), should be referred to in conjunction with Specifications 1,037,914, 1,133,099, 1,171,945 and 1,168,792. The height of the support may be increased by an insert structure, see Figs. 6 and. 7 (not shown).
