Filed: 1921-02-19
Abstract: 179,700. Leyland Motors, Ltd., and Thomas, J. G. P. Feb. 19, 1921. Addition to 115,267. Variable-speed 'epicyclic gearing; clutches.-The parent Specification describes three or four speed and reversing epicyclic gearing comprising a slanting planet spindle 7 carried by a driven shaft 17 and having gears 5, 6 fast upon it each meshing with two sun gears such as 1, 2, 3, 4 adapted to be engaged by clutches and brakes. These clutches and brakes are operated by fluid pressure, the spaces between co-operating members such as 8 and 24 or 27 and 28 being rendered substantially fluid-tight to receive the fluid. The gear 1 has to be clutched to a driving-shaft 11 or held by a brake 22, and for this purpose a double coned member 12, 13 with a central web 21 is splined to it. Splined upon the sleeve of the gear 2 is a webbed clutch member 8, and between the members 8, 12 is a double coned clutch 9 fast upon the shaft 11. Pressure fluid is directed into the spaces between the clutch webs, and after the initial movement closing the clearance between the surfaces to be engaged, these spaces are fluid tight. In the case of the, clutches, the fluid is admitted by central apertures a, c. In the case of the brakes, apertures b, d, e in the fixed brake webs are used. A pump 31 driven by slow gearing 32 from the shaft 11 draws oil from the. bottom of the gear case and delivers it to a cylinder 33, Fias. 3, 4, in which a distributing valve cylinder 34 slides without turning under manual control, ports being arranged as shown in Fig. 5.

Title: Improvements in Methods for Resharpening Rotary Drill Bits of Composite Type.
Inventor: VITRAC JEAN MARIE
IPC: B24B53/00
Filed: 1967-02-07
Abstract: 1,156,082. Resharpening drill bits in situ. BUREAU DE RECHERCHES GEOLOGIQUES ET MINIERES. 7 Feb., 1967 [8 Feb., 1966], No. 5742/67. Heading B3D. A rotary drill bit, e.g. a drill crown 1 comprising abrasive particles such as diamond and a matrix, is resharpened while at the bottom of the bore hole 3, by introducing into the bottom of the bore hole abrasive 4 of a hardness intermediate that of the abrasive particles and the matrix, and moving the drill crown in the abrasive so as to abrade the matrix to increase protrusion of the abrasive particles; the abrasive is then removed by flushing fluid. The abrasive 4 is placed in a container 5 which is lowered into the slightly raised drill string 2 by a cable 6 until it is retained by trigger pins 7. The drill string 2 is then lowered so that the brittle bottom 5a of the container 5 is broken by a push bar, and the abrasive 4 is deposited in the bottom of the bore hole. Instead of using a cable, the container may descent the drill string by gravity or be forced down by the flushing or dilling fluid. The bottom of the container may be of material soluble in the flushing or drill fluid or in a fluid specially injected in to the borehole for this purpose. When used for a full size drill bit 1a the container 5 has a weight 5b to assist breaking of the container. In resharpening a coring tool in situ, the coring tube is used, after removal of the core, to supply the abrasive to the bottom of the bore hole. When drilling with mud, the abrasive may be in a soft plastic container conveyed to the bottom of the hole by the mud, means being provided for bursting or tearing open the container to liberate the abrasive. The resharpening abrasive may be corundum sand, especially when the matrix is steel. If the tool abrasive is tungsten carbide the resharpening abrasive may be quartz sand. Radioactive tracers may be added to the resharpening abrasive so that mud containing abrasive is not stored with the rest of the mud for re-use.

The convolutions pass over a wince f driven by a belt n from the roller d and provided with bearings traversable towards and away from the roller d by screw and nut devices u operated by a hand-wheel (not shown).  The hand-wheel is permanently coupled to the traversing device at the end of the wince remote from the drive thereof and may be clutched when desired to the traversing device at the driven end to displace the wince bodily towards and away from the roller d.  The ends of the rollers b, c and of the wince f are provided with universal joints.

Abstract: 781,511. Surgical drills. HAINAULT, M. Feb. 28, 1955 [March 2, 1954], No. 5878/55. Class 81 (2). [Also in Group XXII] A power-driven surgical drill comprises a rod rotated by driving means, a lower member aligned and coaxially rotatable with the rod and slidable towards and away from the rod, co-operating clutch means on adjacent ends of the rod and the lower member, a compression spring urging the rod and the lower member apart, a central rotary bit secured to the lower member, a second tubular bit surrounding the rotary bit, fixed relative to the rod and keyed to the lower member to allow axial displacement of the lower member and the rotary bit within the tubular bit, the working end of the rotary bit projecting, when the clutch means is disengaged beyond the working end of the tubular bit. A rod 10 within the device is rotated by a drive 1 perpendicular to it and which engages a driven pinion 2 keyed to the rod 10. A sleeve 3 secured to the rod 10 is spaced by a spring 5 from a lower member 4 carrying a boring tool 6. Concentric with the member 4, a tubular rotary bit 7 is secured to the member 4 by a pin 8 slidably engaging a straight or helical slot. When the device is applied to the work, pressure on a pushmember 9 causes clutch teeth 11 on the sleeve member 3 to engage corresponding teeth 12 on the member 4 so that rotation is transmitted to the tools 6, 7. When the boring is completed, lack of resistance at the boring tool 6 allows the spring 5 to separate the clutch teeth 11, 12 and rotation of the tools 6, 7 ceases.
