Filed: 1923-01-16
Abstract: 215,811. Wilhelm, J. H. Jan. 16, 1923. Combined turning, drilling, and milling machines.-In a combination metal-cutting machine for turning, milling, boring and drilling, of the type comprising a lathe bed or machine table and an angular..y adjustable tool-holder carrying a rotating spindle and adjustable relatively to the lathe bed &c., the tool-holder is slidably mounted on a segmental guide above the lathe bed. The base L, Fig. 1, carries a cylindrical column 1 upon which slides a sleeve 2 carrying a lathe bed G which is vertically adjusted by a screw 5 operated from a hand-wheel 3 and is clamped by a handle 27. The outer end of the lathe bed may be steadied by being clamped at 41 to a guideway 21 on a standard 18 adjustably clamped to a slotted table 24 on the base L. A centre 20 is carried by the standard. Large work pieces may be mounted on the table 24, the lathe bed being swung aside about the column 1 and the standard 18 being removed. The upper end of the column carries the segmental guide 7 which supports the tool-holder H whose spindle is driven through a belt 12, Fig. 4, from a motor 9 mounted on a rearwardly extending bracket 11 so as approximately to balance the weight of the tool-holder and prevent binding of the guide 7. Speed-changing mechanism 15, Fig. 1, controlled by a handle 16 may be provided for the tool-spindle which may be fed axially from a hand wheel 17. To facilitate the sliding of the tool-holder along the guide 7 a balance device is provided comprising a system of weights 31, 33, Fig. 3, resting on ledges within the column 1 while a cable 35 secured to a fixed point 36 and to the tool-holder at 40 carries a weight 34 and passes over pulleys 38, 39. The arrangement is such that as the tool-holder descends the guide 7 the weights 31, 33 are successively lifted by the rising weight 34 so that the variable vertical component of the weight of the tool-holder and motor is approximately balanced in all positions. In a modification, Fig. 5, the machine is provided with a fixed lathe bed, while a column 43 carrying the segmental guide and a column 45 carrying the back centre 44 are simultaneously adjustable vertically through screw and bevel gearing operated from a hand wheel 47. The tool-holder H may be traversed by worm and rack gearing operated from a handle 58. In a further modification, a milling-machine table and work-holder of ordinary construction are substituted for the lathe bed.

Filed: 1935-01-22
Abstract: 445,635. Variable - throw cranks. BROWN BROS. & CO., Ltd., and WALLACE,. W., Rosebank Iron Works, Edinburgh. Jan. 22, 1935, Nos. 2052 and 31043. [Class 80 (iii)] [See also Group I] In order to vary the throw of a crank for imparting movement to a displacer or displacers in wave-making apparatus for swimming-baths, a pattern device is provided for varying the throw according to a predetermined cycle. A gear-wheel 2 secured to a shaft 3 and carrying the crank 5 is driven from a pinion 1. The crank is unitary with a nut 6 movable upon a radial screw 7 having a bevel pinion 8 meshing with a bevel pinion 9 carried by a shaft 10 having a disc 11 splined thereon. The disc is movable axiallv of the shaft by a lever 12 connected to a spindle 13 spring-pressed against a cam 14. In the position shown, the disc 11 is locked against rotation by the engagement of the disc with a friction face 23 within a fixed ring 24 or of complementary teeth on the disc and the ring ; consequently, as the wheel 2 rotates, the screw 7 is rotated so that the crank is moved towards the axis of the wheel. When the disc 11 is moved to the right or left it is freed for rotation ; when in engagement with the shaft 3, there is no relative rotation of the parts 7, 10 and there is no radial shift of the crank, but when the disc is moved into engagement with the disc 19, the spindle 10 is rotated at a reduced rate through the gears 20, 21, 22 and the screw 7 is rotated to move the crank towards the circumference of the wheel. The pattern device may be constituted by a rotary disc operating electrical contacts whereby the lever 12 may be operated electromagnetically.

Title: Improvements in or relating to a method of retreading pneumatic tyre casings
IPC: B29D30/54
Filed: 1953-01-23
Abstract: 719,040. Retreading tyres. HAWKINSON CO., P. E. Jan. 23, 1953 [May 19, 1952], No. 2081/53. Class 87 (2) A method of applying a new tread to a worn tyre of the type having a thick crown tread portion 6 and side wall portions 5 comprises removing part of the old tread to leave a peripheral trough 8, filling in the trough with uncured tread material 11 and placing the tyre and newly-applied material in an annular mould 19 which is smaller in diameter than the tyre and has a transverse width greater than that of the normal cross-sectional arc of the worn tread portion and makes wide sealing contact with the shoulders 18 of the trough. The method has particular application to tyres used on aircraft, which do not have welldefined shoulders at the sides of the tread. The trough 8, Fig. 1, is preferably buffed out in a lathe-type machine using a buff-head of a type which produces a smooth buff to obtain a proper vulcanizing surface, the tyre being inflated so that the distance between the bottom of the trough and the underlying cord carcase is approximately uniform. The uncured tread material 11 is shaped so that it may be inlaid in the trough 8 and is tacky on the three surfaces where it meets the bottom and sides of the trough, the latter being tapered as shown. The sheet metal band which forms the mould 19 is folded into tread design-forming ribs 21 and is heated by a steam coil 23, resembling the mould described in Specification 420,829 except that it is curved and has no side flanges, but the edges are turned up and form grooves for reinforcing wires 25. The diameter of the mould 19 is less than that of the tyre, and the tyre beads are therefore spread apart by spreading device 26, as described in Specification 420,829, to reduce the diameter of the tyre whereby it may be placed in the mould. The beads are then allowed to come together again, with the result that the new material 11 and the adjacent shoulder portions 18 expand into close contact with the mould. The tyre is then mounted on a rim with an inner tube inside. side pressure plates are applied to its walls as described in Specification 442,474, the inner tube is inflated, and the tread material is cured by circulating steam through the coil 23.

Abstract: 345,731. Rotary cement kilns. JORGENSEN, M. VOGEL-, 24, B³lowsvej, Copenhagen. Jan. 21, 1930, No. 2129. [Class 51 (ii).] In a rotary kiln for burning cement the total inside area in the case of a dry process kiln, or the area from the evaporating and preheating zone to the discharge end in the case. of a kiln for the wet process, is made at least 120 times as great, as the cross sectional area at normal diameter measured inside the lining. The increased surface area may be obtained by increasing the length of the kiln, by increasing the diameter in the sintering zone, and preferably also in the transition zone between the sintering and calcining zones, or by splitting up the calcining zone, and preferably also the preheating zone, into a number of separate tubes. For the dry process the charge may be moistened and formed into lumps or briquettes, and in the wet process a part of the water content of the slurry may be removed before it is fed to the kiln. Stirring and heat exchange devices which move the material without whirling it up may be fitted in the preheating and calcining zones, and means may be provided for forming an accumulation of material at the beginning of the calcining zone.

Abstract: 1,095,817. Gyroscopic apparatus. TOKYO KEIKI SEIZOSHO KABUSHIKI KAISHA. Jan. 18, 1966 [Feb. 26, 1965], No. 2319/66. Heading G1C. A meridian gyroscopic instrument for use with a transit theodolite in surveying, comprises a gyro rotor 14 mounted inside a casing 15 having vertical shafts 17, 18 supported in bearings 7, 13, the weight of the case being balanced by flotation in a liquid 16 in a cylindrical body 10, an outer casing 19, rotatable manually on the body 10 on bearings 21, carrying markings (not shown) to indicate the azimuth position of the gyro spin axis, and non-contact making detecting means, e. g. an E-core pick-off 23, between the casings 15, 19 to indicate alignment of the outer casing 19 with the gyro spin axis, and thus the meridian. In use the basic plate 8 of the gyro is levelled using screws 9 and since the rotor spin axis is constrained to movement in a horizontal plane, the casing 15 will precess to align the spin axis with the meridian. The outer casing 19 is then rotated to align the two casings, the theodolite being mounted atop the casing 19. The E-core pick-off may be replaced by a simple pointer or light beam and scale if desired. The liquid 16 damps the movement of the casing 15, and in alternative embodiments the weight of this casing is not supported by. flotation but by magnetic expulsion or attraction or by a fluid bearing.
