Abstract

446,419. Elastic - fluid turbines. MAVOR & COULSON, Ltd., and MAVOR, J. B., 47, Broad Street, Mile-End, Glasgow. Oct. 24, 1934, No. 30460. [Class 110 (iii)] [See also Group XXX] In compressed air turbine-driven beltconveyers a brake is released by compressed air in the act of turning on the air for the turbine. Fig. 1 shows a turbine rotor A the shaft B of which carries a multiple-plate friction brake 7 which is made effective by the pressure of a spring 4 acting through a rocking arm 6. The spring 4 bears on a piston 3 moving in a cylinder 2, to which air is admitted to compress the spring 4 and release the brake 7 through a piston rod 5 and the arm 6. Fig. 4 shows a rotary hand cock C with a barrel 8, provided with two opposite openings 9, depicted in the position in which air is cut off both from the turbine and from the pipe 12 leading to the cylinder 2. An adjustable escape passage 13 is in this position connected by a byepass to the pipe 12, thus allowing the spring 4 to expand without back pressure on the piston 3. On turning the barrel 8 clockwise the passage 13 is first cut off air is then admitted to the cylinder 2 to release the brake 7, and afterwards to the turbine casing F, and in stopping air is cut off from the turbine before it is cut off from the cylinder 2. An adjustable air-release 15 is provided in the cylinder 2 to regulate the speed of the piston 3. The cylinder 2 may be disposed laterally of the shaft B, as shown, or in line therewith, the piston-rod 5 then operating the brake 7 through the agency of a yoke. The brake 7 may be mounted on any rotating part of the conveyer. Specifications 263,540, [Class 110 (ii)], and 350,799 are referred to.
