Title: Improvements relating to shaft packings or sealing devices
IPC: F16J15/44
Filed: 1947-12-29
Abstract: 651,342. Stuffing-box substitutes. FIAT SOC. PER AZIONI, and BALDWIN, P. S. Dec. 29, 1947, No. 34349. Convention date, June 27, 1945. [Class 122(v)] In a packing device for an axially movable shaft 1 projecting through a wall of a fluid pressure chamber 2, a floating and elastic sealing ring 4 is provided for the shaft 1 with elastic means 6 for holding the front surface of the ring 4 in constant contact with the wall of the chamber 2 to maintain a seal when no fluid pressure is exerted in the chamber 2, the bore of the ring 4 being formed with a revolution surface having a curvilinear generatrix and being, when no fluid pressure is exerted in the chamber 2, in contact with the shaft 1 along a line formed by the apex of the curved surface while the remainder of the bore is out of contact with the shaft 1, the outer peripheral surface of the ring 4 being constantly out of contact with the walls of the chamber 2 so that the ring 4 is subjected to axial and radial fluid pressure when fluid pressure is admitted to the chamber 2, whereupon the area of contact between the box and the shaft 1 increases. The ring 4 is pressed against the chamber wall by a metal washer 5 acted upon by a helical spring 6 bearing on the chamber 2. When fluid pressure acts on the ring 4 only the portion of the box adjacent the ring face in contact with the wall is expanded into contact with the shaft 1 while the other portion is acted on by the fluid pressure and is maintained out of contact with the shaft 1. The bore may be expanded until a maximum of half the bore is in contact with the shaft 1. When the fluid pressure is released the ring 4 assumes its normal shape making true contact with the shaft 1.

[Class 40 (iv)] [Also in Group XL (c)] A subaqueous compressional wave sender or receiver comprises a cup-shaped cast metal casing a containing a vibrator unit formed of steel face plates bl, b<SP>2</SP>, two piezo - electric crystal layers c<SP>1</SP>, c<SP>2</SP> and a steel interplate d. The unit rests in the casing on an L-section rubber ring f. The face plates b<SP>1</SP>, b2 are electrically connected together by a wire h<SP>2</SP> and to the casing a by a head h<SP>3</SP>. Interplate d is connected to a lead h<SP>1</SP> passing out through an insulating bush g. The crystal layers c<SP>1</SP>, c<SP>2</SP> are each formed of a series of parallel rows of quartz crystal plates with substantial spacing between the rows. With this arrangement the face plates move as a whole, piston fashion, and a considerable economy of crystal material is effected, as the crystals cover only about one-third of the area of the face plates. The crystal pattern is obtained by using a template (Figs. 3 and 7, not shown) which is removed after the crystals have been joined by adhesive to the face plates by the method described in Specification 611,738. The two face plates are then applied on opposite sides of the adhesive coated interplate d to complete the unit. More than two crystal layers may be used with additional interplates. Also other crystal patterns may be used.

Abstract: 325,299. Pearce, L. T. Nov. 27, 1928. Milling helical surfaces; milling - machines. - Aircraft propeller blades 25 and articles of a like irregular cross-section are machined by mounting them between chucks 24 and centres 26 in gear wheels 17, 18 and driving them past a milling - cutter, grinding wheel, or polishing wheel 66 which is mounted in a slide whose movement towards and from the work is controlled by a follower 65 the latter co-operating with patterns 29 mounted similarly to the work blanks, in gear wheels 19, 20 which are intergeared with the wheels 17, 18 so that the blank - and - pattern carriers may be rotated in unison by a shaft 35. The gear wheels 17, 18 are tied by stays 21 and a central sleeve 15 which is loose on a shaft 13. The pattern carrier is built similarly but is provided with a cylindrical shell 59 of plates, slots in which are left to accommodate the patterns. The shell provides a bearing for the follower between periods when the follower is contacting with a pattern. Each pattern-spindle and each blank carrying spindle is provided with a planet wheel such as 42, geared to a sun wheel 40 which is normally fixed but which may be adjusted through worm gearing 44, 46, 47 by a handwheel 50 so that the work and pattern lie in the peripheral surfaces of their carriers during the working operations. The epicyclic gear is designed so that each blank and its corresponding pattern are rotated through 180‹ between successive operations of the cutting tool. The machine is driven by an electric motor 32 through a chain wheel 34 and a clutch 38. A feed screw 67 for traversing the cutter slide may also be driven from the motor through gearing 68 .. 72 and a clutch 73. The worm shaft 47 may be automatically driven through a clutch 58. Bosses 93 on the work may be machined by disengaging the clutch 38 and engaging the clutches 58, 73. By engaging only the clutch 73, the edges of the work may be machined. In a modification, the blank and pattern are caused to move approximately parallel to themselves during .each cutting operation by causing a roller on one of the planet wheels to move the worm shaft 47 longitudinally, thereby temporarily displacing the sun wheels and compensating for the angular displacement of the blank &c. carriers. According to the Provisional Specification the apparatus may be adapted to function as a lathe &c. attachment.
