Title: Improvements relating to the shanks of twist drills or similar drilling tools
IPC: B23B45/12
Filed: 1928-02-09
Abstract: 305,813. Abel, J. H. Feb. 9, 1928. Drills ; ratchet braces.-To enable twist drills and similar tools to be rotated by a reversible ratchet spanner, a hexagonal nut or other non. circular portion shaped to fit the spanner is secured to or formed on the drill shank. The nut, having a lower flange on which the spanner may rest, may be secured directly to the drill shank or may be secured to the shank of a three-jaw chuck which grips the drill. In another form for use with Morse taper drills, the nut 3 having a flange 4 is fitted to a socket 6 for holding the drill and having a slot 9 for an ejector. In each form a pointed stud 2 is provided, on the socket, the chuck spindle or the drill itself, for abutting against a drill stand. The stands described in Specifications 222,171 or 292,770 are preferably employed, the cylindrical portion 2 of the shank being adapted for co-operation with the feeding sleeve described in Specification 222,171.

Title: Improvements relating to work holders for lathes
IPC: B23B31/30
Filed: 1942-03-28
Abstract: 553,049. Chucks. BENTON & STONE, Ltd., and MILNER, C. E. March 28, 1942, No. 4141. [Class 83 (iii)] Means for securing work such as a pipe elbow b to the hollow spindle a of a lathe comprises a fluid-operated work holder c mounted on the spindle end, fluid being supplied to the holder by a hydraulic intensifier within the spindle. The work-holder has a forwardly extending portion including a cylinder d with a piston e having a hollow piston-rod g carrying a spindle h on which the work is screwed. By rotating finger piece the work may be drawn against the face of the work-holder and is further gripped by the admission of high pressure fluid to cylinder d through a pipe n. This fluid is obtained from an intensifier comprising a cylinder k and ram o, the latter being actuated by the head of a rod q attached to the piston s of a large cylinder r supplied with compressed air or liquid under pressure.

Title: Improvements relating to automatic machines
Inventor: BOOTH RICHARD HERBERT
IPC: G05B19/35
Filed: 1954-02-12
Abstract: 797,504. Programming for machine-tools. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 7, 1955 [Feb. 12, 1954], No. 4145/54. Class 83 (3). [Also in Group XXXVIII] An automatic machine-tool comprises a relatively heavily-loaded part displaceable to cause relative displacement of a tool and a workpiece, means for displacing a less heavily-loaded element in response to an electrical analoguesignal derived from a record, and hydraulic servo-means responsive to relative displacement between the part and element for displacing said part so as to tend to reduce said relative displacement. In Fig. 1, the machine comprises a table 4 carrying a workpiece 5 which is rotated uniformly whilst a milling-cutter 1 is moved radially in and out. The cutting-head 1 extends from the heavily-loaded part 2 slidable on a fixed part 3. Instructions for the displacement of part 2 are recorded on a magnetic or punched-tape 7, fed into tape-reader 8, the output of which is converted to analogue form by a converter 9, and fed to an amplifier 10. The output of this serves as an error signal input for a servomotor 11 which rotates a lead-screw 13 through gears 14. An additional gear 15 drives a converter 16, e.g. a potentiometer, which sets up an analogue signal, of the same type as that produced by the converter 9, fed with negative polarity to amplifier 10. The less heavilyloaded element is a nut 17 non-rotatably mounted on the lead-screw, so that its displacement D from a datum 19 is the required displacement D<SP>1</SP> of part 2 from a datum 6. A piezo-electric crystal 20 is mounted on an extension 21 of part 2, and the nut 17 bears on this crystal. Relative displacement between the nut 17 and part 2 strains the crystal, which produces an input for amplifier 22 controlling an electromagnet 24 adjusting the valve 25 of an hydraulic cylinder-and-piston 26, 27 which moves the part 2 in the sense to reduce the relative displacement. Preferably the arrangement is such that valve 25 is in the neutral position when there is a small strain on the crystal. Means may be provided whereby, if the nut 17 moves rapidly away from the part 2, this part is automatically driven in the same direction to re-establish engagement between the nut and crystal. A crystal overload cut-out may be used. Figs. 2-6 (not shown) illustrate embodiments in which the crystal is replaced by a pair of strain-gauges arranged to be strained differentially by relative movement of nut 17 and part 2; by an armature on nut 17 arranged to increase or decrease the flux through one or other of two coils mounted on part 2; by a differential capacitance, or by a magslip transmitter mounted on nut 17, its shaft being attached to a gear meshing with a rack on part 2. Further, the relative displacement may tilt a mirror deflecting a beam of light between two photo-electric cells, which combine differentially to produce an output for amplifier 22. Specifications 796,994, [Group XXXVI], and 797,503 are referred to.

Abstract: 104,567. Doulton, H. L., Pleace, R, J., and Williams, L. B. March 24, 1916. Mixing-valves. - A screw - actuated lift valve is so arranged that the cold-water supply alone acts on the underside of the valve member, the hot water acting against a flexible packing - diaphragm. During the first part of the opening movement, the valve member I' lifts from its seat and allows cold water to flow from the passage C to the outlet passage F. A further movement lifts the flange R from the seat and allows a mixture of hot and cold water to flow; the final movement brings the disk O against the underside of the seat to shut off the cold water, while allowing the hot to flow. The packing-diaphragm M is clamped between the casing and cover L and between two parts of the valve member.

The unit is reciprocated by a piston rod 7 on which lateral stress is avoided by providing a shoe 12 in sliding engagement with an adjustable inclined member 9. Roller 3 may be driven. In discharging a workpiece, lowering the roller 4 and feeding unit from the Fig. 1 position allows the machined workpiece to engage a deflector 13 and to fall into a shoot 16. Simultaneously a further workpiece moves on to the conveyer surface 11a where it is stopped by the member 9. As the piston rod 7 is extended, the further workpiece, now located by a recess 17 in the member 9, is raised into the machining position and a still further workpiece is positioned on a shoot 10 against the surface 11. In a modification, Fig. 4 (not shown) the shoe (12) of the first embodiment is dispensed with, the roller (4) being mounted on a pivoted arm (20) actuated by piston rod (7). Both constructions provide adjustment for workpieces of different diameters. Grinding, honing and finishing operations are specified.
