Abstract
705,444. Stuffing-box substitutes. ALLEN, SONS & CO., Ltd., W. H., and SMITH, F. S. Nov. 23, 1951, No. 27558/51. Class 122 (5) In a labyrinth gland for a movable shaft 1 passing through a casing 9 separate annular baffle elements 3 are frictionally held with a small clearance 4 and in substantial concentricity with the shaft between spacing rings 10, the baffle elements being dimensioned so as to permit their radial displacement. The baffle elements 3 and spacing rings 10 are axially secured between the inner end wall 6 of a gland housing 5 bolted to the casing 9 and a cover ptate 11 bolted to the housing, the baffle elements having large clearances 13 in the housing bore and the spacing rings having large clearances 14 with the shaft and fitting the housing bore. The baffle elements may be cone shaped at their internal diameters which may be varied to correspond with steps, grooves or collars of a stepped or grooved shaft. The housing 5 may be omitted and the baffle elements and spacing rings secured between a cover plate attached to the casing 9 and an internal flange on the casing. To facilitate assembly of the gland thereon the shaft may have a tapered portion adjacent the gland bearing portion. When the casing 9 is axially split the housing may be formed of two parts each having an end wall and a peripheral flange which flanges are secured 'together and fit in an internal groove in the casing or, alternatively, each baffle element and spacing ring is also axially split and the baffle elements are aligned by axially disposed pins fitting aligned holes therein which pins also pass with substantial clearance through aligned holes in the spacing rings, the complete gland assembly being retained in a groove in the casing. The baffle elements may be slightly deformed to increase their frictional grip. Specification 705,381 is referred to.
