Title: Improvements in ink stands and bottles therefor
IPC: B43L27/00
Filed: 1933-01-16
Abstract: 398,083. Inkstands. ANGUS, J. A. and THORPE, J., (trading as ANGUS & CO.), 152, Arthurton Road, Northcote, Victoria, Australia. Jan. 16, 1933, No. 1424. [Class 146 (iii).] An inkstand is provided with more than two abutments spaced from and above its supporting surface, and arranged uniformly in circular configuration to receive the ink bottle, which is similarly provided at its lower edge with spaced peripherally projecting members adapted when the bottle is rotated to become wedged between the abutments and the supporting surface, whereby the bottle is pressed upon and maintained in close contact with the supporting surface. In the construction shown in the Figure, a series of spaced tongues 5 are pressed upwardly from a metal base 1 in a circular arrangement to form seatings for two bottles 2. The inturned ends 6 of the tongues 5 are adapted to engage a bead 7 on the lower edge of the bottle, and this base has a series of gaps 8 therein, which can be aligned with the tongues 5 for mounting the bottle on the stand, the bottle being pressed downwards so that the tongues pass through the gaps, and then rotated to bring the bead 7 beneath the inturned portions 6. The portions of the bead between the gaps are tapered to give a wedging action. The stand may be formed with circular depressions which form seatings for the bottles, and the tongues 5 may be pressed up out of the walls of these depressions. Alternatively, the tongues may be replaced by pins which project inwardly from the walls of the depressions. In a modification, the bead 7 is replaced by a number of spaced lugs which may be aligned with gaps formed in the wall of a seating and are then received in an annular groove at the base of the seating, the upper edges of the portions of the groove between the gaps being inclined to provide a wedging action on rotating the bottle.

Title: Improvements in or relating to drilling machines
IPC: E21B21/01
Filed: 1948-01-16
Abstract: 632,036. Drilling long holes; drills. INGERSOLL-RAND CO. Jan. 16, 1948, No. 1453. Convention date, Dec. 21, 1945. [Class 83 (iii)] A rock-drilling or like machine has a tubular rotary feed screw 33 to receive through its bore 103 fluid for cooling the bit and removing cuttings, a tubular working implement 23, 24 coaxially secured to the screw, and a seal 95 in the screw urged by the fluid pressure to seat against the working implement. The working implement comprises a diamond cutter 30 at the end of a plurality of tubular sections 23 which are joined by connectors 24 and have non-retmn valves 29 to prevent the cooling and clearing fluid from returning to the machine; the connectors 24 are in the form of screw-threaded adaptors, the rear one of which is clamped within a chuck 34 attached to the screw 33 so that the end of the adaptor presses against the seal 95 which is retained within a two-part hollow piston 88, 89 slidable within the bore 103 of the feed screw. The piston 88, 99 has a one-way spring-urged valve 92, and is connected by a member 87 with a rearwardlyextending tubular extension rod 85. The rod 85 is slidably received within a sleeve 82, which is in threaded engagement with a plug 80 similarly engaging the end of the feed screw. The plug 80 receives a swivel 78 having a valve 79 to regulate flow of the fluid into the feed screw. The liquid passes therefrom to the drill 30, and, by passing through ports 104 in the member 87, exerts pressure on the surface 105 of the piston 88 so as to press the seal 95 against the adaptor 24; a spring 102 also co-operates to this end. The motor of the machine is fed with pressure fluid through a valve 57 and inlets 59 leading to a rotor chamber 44. The rotor 45 surrounds and drives the feed screw through splines 46, 47 permitting axial movement of the screw relative to the rotor. A pinion 61 attached to the rotor engages a pinion 62 keyed to a hollow shaft 63 having thereon gears 64 of different sizes adapted, selectively, under the control of a rod 71 to drive one of a set of pinions 65 keyed to a feed nut 66; this nut is in screwthreaded engagement with the screw 33 so as to feed the latter. The rod 71 for selecting the desired drive is actuated by a rack 74 by means of a pinion 75. The feed screw is adapted to be retracted by a hand wheel 76 keyed to the feed nut 66 from the position illustrated in Fig. 1, so that another section 23 and adaptor 24 can be added to the working implement without moving the supporting column 21 of the'drill.

Title: Gravity meter
IPC: G01V7/10
Filed: 1939-01-16
Abstract: 511,918. Measuring gravitational forces. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Jan. 16, 1939, No. 1493. Convention date, Jan. 22, 1938. [Class 97 (iii)] Relates to gravity meters in which a mass or masses, 31, 31A, are clamped to a horizontal elastic thread 30 with their centres of gravity radially offset from the thread so that by twisting the latter from one or both its supports 25, 25A, the eccentric masses may be moved by torsion until the system approaches a position of instability and becomes highly sensitive to changes in the force of, gravity. In order to facilitate levelling of the instrument, the casing 21, to which the ends of the thread 30 are connected, may be freely suspended, e.g., by threads 8, from two points 7, 7A, lying in the vertical plane through the thread 30. In order to eliminate undesirable sagging of the thread 30, the masses 31, 31A, may be immersed in a liquid and have weights equal'to the weight of liquid displaced, the centre of buoyancy of each mass lying in the axis of the thread. In order to make the sensitivity independent of changes in the gravity torque two masses 31, 31A may be fastened to the thread 30 at spaced points and have their centres of gravity angularly displaced in a plane perpendicular to the thread by approximately 90 degrees. As shown the masses 31, 31A are eccentrically weighted spheres and carry mirrors by which a ray of light may be reflected to indicate variations in position due to changes in the force of gravity. The casing 21 may be suspended in a casing 5 which contains liquid communicating with the liquid in the casing 21 through orifices 20. The instrument is maintained at constant temperature by enclosing the casing 5 in a housing 1 containing liquid which is agitated by the stirrer 12 and heated by the thermostatically controlled electric heater 4.

Title: Improvements in glass bottle making
IPC: C03B9/06
Filed: 1932-01-19
Abstract: 392,285. Glass manufacture. HAILWOOD, E. A., Beacon House, Texas Street, Morley, near Leeds. Jan. 19, 1932, No. 1569. [Class 56.] Relates to the method of making a doublewalled vessel, such as a vacuum flask, by forcing inwards a part of the outer vessel, while the glass is still hot and plastic, and shaping it into the inner vessel by means of a tool. According to the present invention, a bulb A, Fig. 1, is blown in a mould A<1> in such a way that the bottom C of the bulb is relatively thick, and this thick end provides the glass for the formation of the inner vessel and the neck of the finished flask. The neck P<x>, of the bulb forms the tube through which air is evacuated from the space between the walls of the vessel, the tube being sealed as usual by fusion at the end of the operation. When the bulb has been blown to the extent shown in Fig. 1, a plunger D, which is preferably rotated, is forced into the mould and forms the neck B of the flask and an upstanding tubular portion G, Fig. 2. The plunger is then withdrawn, and a scissor-like tool of the known kind is inserted in the tube G and is operated in the known manner to shape the inner vessel. The shaping tool and the plunger D may be operated by the one driving device F, or the two tools may be mounted near to one another, the mould being movable between them.
