Title: Improvements in comparator gauges
IPC: G01B5/08
Filed: 1944-09-13
Abstract: 587,587. Linear - dimension gauges. SIRVENT, P. B. Sept. 13, 1944, No. 17450. Convention date, Sept. 29,1943. [Class 106 (ii)] A comparator gauge for checking inside diameters or bores over a wide range comprises a frame 1, at least two measuring fingers 2 which can swing relatively to each other, each arm being secured adjustably to one end of an arm 8 which is pivoted at the other end to the frame 1 at 11, and means operated by the movement of each finger 2 for actuating an indicating-pointer 22a carried by a lever 22. The fingers 2 extend through a slot in the frame, one having a single and the other two ballgauging surfaces for engaging the work 46 carried by a vertically adjustable table 3. Each finger is bent at 45 degrees at its lower end, fitted into the boss 43 of a disc 4 which is adjustably secured to a further disc having a flange 6 to which is secured the arm 8. An extension 6a of the flange 6 engages a ball B mounted on a pin 17a adapted to slide vertically, against the action of a spring 19, in a fixed bracket 18. The indicating-lever 22 is carried by an arm 21 pivoted to the bracket 18 at 23, the other end of the arm having a sloping surface 20 co-operating under the action of a spring with the lower end 17b of the pin 17a. Movement of the fingers 2 is thus communicated to the pin 17a which moves the pointer 22a by engaging the sloping surface 20 of the arm 21. The fingers 2 can be pre-set to suit the size of bore to be checked by adjusting the discs 4 relatively to the other discs, a key being provided for this purpose ; the arms 8 are then locked against movement by means of transverse shafts 32 attached to the arms and passing through slots in the frame to receive locking nuts 33 (not shown). The pointer 22a moves under a window 26 and between two adjustable stops 30 which can be set to indicate the limits of tolerance of the bore being checked. The table 3, slotted to accommodate the fingers 2, is supported by a post which passes into the casing where it is adjustably clamped by a pair of hinged members. These members are held together when in the unclamping condition by spring clips mounted in grooves therein. A compression spring below the post counteracts the weight of the table in the undamped condition.

Abstract: 1421377 Bearings; balancing shafts ROLLS-ROYCE (1971) Ltd 13 April 1973 [18 April 1972] 17793/72 Headings F2A and F2U [Also in Division F1] A rotatable assembly comprises a shaft, a bearing supporting the shaft for rotation and a bearing housing within which the bearing is disposed, the bearing housing being constructed so as to be capable of deforming under abnormal out-of-balance forces on the shaft to allow orbiting motion of the shaft around its original axis. The invention is described with reference to the shaft 11 carrying the fan of a gas turbine ducted fan engine, the shaft being supported in two roller type bearings 21, only one of which is shown in Fig. 3, and in a ball type thrust bearing 19 which is disposed adjacent the fan rotor disc. The bearing 19 comprises an inner race 41, an outer race 42 and balls 43, the outer race being supported in a housing which is formed in two parts, an inner part 48 and an outer part 49. The inner and outer parts are spaced apart to define a cavity 40 therebetween in which is disposed a deformable member in the form of a flanged toroidal ring 58. The inner part 48 is formed with a flange 55 of frusto-conical form which is received within an annular channel 57 defined between the outer part 49 and a flange of a stator support structure 61, two ring members 65, 66 being disposed between the flange and the sides of the channel, and a spring member 67 being disposed between the ring members and the bottom of the channel. The outer part 49 of the bearing housing is secured to the stator structure by bolts 59. The inner part 48 is secured to a member which provides the outer members 51, 52 of labyrinth seals 46, 45 by means of bolts 50, a " squeeze film " space 54 being defined between the seal member and the outer race 42. The outer race 42 is prevented from rotation by means of dogs 70, 71 on the race and seal member respectively. The inner and outer parts 48, 49 are also prevented from rotation by means of dogs 72, 73 on the two parts. In the event of the rotor disc becoming unbalanced the member 58 deforms and the shaft orbits. The surfaces of the frusto-conical flange 55 are of part-spherical form centred on the predicted node point on the axis.

Filed: 1926-07-23
Abstract: 255,893. Dehandschutter, R. July 23, 1925, [Convention date]. Blowing.-A machine for blowing tableware has means for oscillating the finishing mould about its longitudinal axis in order that the ware may be free from seams or mould marks. A device for supplying a constant volume of air for blowing each article is also provided. The machine comprises a horizontal shaft 4, Fig. 1, journaled in uprights 2, one half of the shaft having an axial boring 6 to enable air to be supplied to a blowing- nipple 8. A ring mould is fitted on the shaft, one half, 10<1>, of the mould being fixed, while the other half, 10<2>. is movable by means of a bolt 11. A two part parison mould 12 is hinged to a crosspiece 13. The finishing mould 13<1> is in two parts and is mounted on a plate 15 which can be oscillated about its axis by a crank 19, connecting rod 18, rack 17, and pinion 16. In use, after the parison is formed, the mould 12 is opened and the shaft 4 is turned over to bring the parison into the finishing mould. When the mould is closed, the crank 19 is rotated so that the mould is oscillating while the article is being blown. Air suppby for blowing.-The device for supplying air consists of a piston 23, Fig. 2, which moves in a cylinder 7 between adjustable stops 22. A compressed air pipe 24 is connected with the ends of the cylinder by way of a two-way cock 26<1> and branch pipes 24<1> and 24<2>. Another pipe, 25, which is connected with the passage 6 in the shaft 4, is also connected with the ends of the cylinder through a two-way cock 26<2> and branch pipe 251, 25<2>. The two cooks are linked to one another, so that when compressed air is admitted to one end of the cylinder, the movement of the piston forces a definite volume of air, at a lower pressure, through the pipe 25 into the parison which is being blown.
