Title: Improvements in and relating to coal-cutting and loading machinery
IPC: E21C27/02
Filed: 1944-02-07
Abstract: 579,342. Coalcutting and loading machines. SWALLOW, R. H. Feb. 7, 1944, No. 2195. [Class 68 (i)] In a coal-cutting and loading machine having horizontal cutting means for undercutting the seam, a vertical shearing cutter extending in advance of the undercutter, and a conveyer which carries the cut coal sideways and discharges it on to a loading belt, the cutters are so arranged that as the machine advances it first shears about the full height of the seam and then undercuts across substantially the full width of the machine, the latter following in the wake of the cutters so that the loading belt may be arranged immediately alongside the coal face. As shown, the machine motor drives through gearing 1, 2 a shaft 2a from which, through sprocket 3, a shearing chain 3b is driven ; the bearing of the front sprocket 3a is vertically adjustable to allow a different size of sprocket to be substituted for a different thickness of seam. The shaft 2a also drives through a clutch an aligned shaft 2b which, through gearing 4, 5 and chain 6a drives a shaft 7a carrying a polygonal drum 14 driven therefrom through gearing 8 ... 11, the drum driving a scraper chain conveyer 21a which delivers coal to a loading belt 24 ; the shaft 7a also drives through gearing 12, 13 a cutter bar 20 over which the coal passes by an apron 23 to the conveyer 21a. The coal cut by the shearing cutter may be deflected forwardly by a guard or baffle. A fender 25 guides the machine. To facilitate transport, the conveyer frame is in two parts so that the front part may be detached and placed on the other part, and the cutter bar 20 is removable. The machine is advanced by means of rope passing from a haulage drum 27a, Fig. 5, rearwardly over a pulley 28 and forwardly to an anchorage 30. In thick seams, further cutter bars are provided at different levels ; thus, two machines may be superimposed, one of which may drive the shearing cutter and the top cutter bar, while the other drives the lower cutter bar and the conveyer. The Provisional Specification also describes a form in which superposed cutter bars are carried by vertical standards at each side, a vertical cutter chain or cutter bar in advance of the standards cutting a path therefor, and means being provided so that the drive can be coupled to either end of the cutter bars or conveyer.

Title: Improved process of impregnating wood
IPC: B27K3/34
Filed: 1927-01-26
Abstract: 265,206. Montan, Inc., (Assignees of Coolidge, J. R.). Jan. 26, 1926, [Convention date]. Proofing against bacteria and fungi; waterproofing; fireproofing; proofing processes; proofing-compositions.-A process for impregnating wood, fibre board &c. comprises impregnation, preferably under pressure and at a high temperature, with a substance, which easily penetrates the material, followed by impregnation with a wax of high melting point such as montan wax. The substance used in the first operation is preferably an oil miscible with or which dissolves the wax used, and may comprise a toxic agent such as creosote oil or #-naphthol. In the impregnation of wood, after seasoning and preliminary treatment to remove water, the wood is impregnated with a liquid which mixes readily with montan wax, such as carbon tetrachloride, turpentine, kerosine, or petroleum distillate. Preferably the operation is carried out in pressure apparatus. After impregnation, the pressure is reduced to withdraw part of the liquid from the wood. Hot montan wax is then admitted, preferably at a temperature of 225‹-240‹ F., and at a pressure depending on the depth of impregnation desired. The wood may be stored between the two operations. When it is desired to protect the wood from decay, creosote oil, or an inert oil mixed with #-naphthol, is used instead of the solvents mentioned above. In this case, only the outer parts of the wood are impregnated to a depth up to half an inch. #-naphthol may be mixed with the montan wax when the first impregnant is an inert oil. Alternatively, the process may consist of impregnation with a water solution of sodium fluoride, zinc chloride, &c., seasoning, and finally a light impregnation with montan wax. Sodium biborate may be used in this maner for fireproofing. Oils or other waxes may be mixed with the montan wax in any of the above processes for the purpose of rendering penetration easier, or colouring materials, e.g., oil soluble dyes, may be added. Candelilla. and carnauba wax may be substituted for montan wax.
