Title: Improvements in Tyres for Vehicles.
Inventor: MORTIER GEORGES ALBERT
IPC: B60C7/12
Filed: 1916-08-19
Abstract: 103,081. Mortier, G. A. Aug. 19, 1916. Spring wheels with continuous outer rigid ring and rubber-ring and like cushions.-A rigid metal or other ring of I-section is embedded in a solid rubber tyre and spaced from the felloe. The sides of the tyre are gripped between ring-plates 4 secured to the felloe and formed with inwardly projecting ribs lying between the inner and outer walls of the ring. The outer wall 7 may be concave so as to provide an air space 9 in the tyre. The outer surfaces of the inner wall may have recesses or continuous grooves 8 so as to facilitate the distortion of the rubber under compression. Fig. 2 shows the ring formed of two members so as to be divided vertically.

Title: Improvements in or relating to polishing machines
IPC: B23F19/04
Filed: 1931-04-21
Abstract: 375,475. Grinding and trueing teeth of gear-wheels. POOCK, O. M., 1517, East 3rd Street, Dayton, Ohio, U.S.A.- (Assignee of Powell, W. C., and Donovan, I. [Administrator of Mullen, T. J.]) ; Dayton, Ohio, U.S.A.) April 21, 1931, No. 11798. Convention date, April 28, 1930. [Class 60.] Grinding interfitting parts together.-A polishing machine comprises a number of rotatable polishing tools, one tool serving to rotate the work and having its direction of rotation automatically reversed while in engagement therewith. As applied to a gear polishing- machine, the work is supported between a positively driven tool 11 and two freely rotatable tools 12. The shaft 13 of the member 11 is driven from a motor 30 through a belt 28, a shaft 24, and worm gearing 25, 26, and is mounted in a housing 15 in a bearing which is adjustable by a wheel 19 and may be clamped in adjusted position by a bolt 20, according to the size of the work. The tools 12 are carried in slides 51 adjustably held by bolts 52 on a supporting member 49. A belt conveyer 69 carries studs 72 on which the gears are mounted and held while being polished, an unpolished gear moving into position automatically as the supporting member 49 is withdrawn and then returned. The movement is effected by a manually controlled fluid-pressure actuated piston-rod 54 which actuates links 61, 60 to move the member 49, and a segmental portion 77 of a shaft 78 which, through a link 74 engages the conveyer to move it forward through one step. The shaft 78 is returned by fluid pressure. A worm-gear 37 meshes with a worm on shaft 24 and drives a shaft 35, Figs. 3 and 9, in frictional engagement with a disc 39, which carries projections 46, 47 which in turn strike a rod 44 during a, polishing operation to rotate a shaft 32 forming the control for the reversing and on-off switch housed in the casing 31. A roller E on a resiliently held arm F engages a cam D on the shaft 32, and enters notches A, B, C therein to retain the switch in the starting, off, and reverse positions respectively. The roller is caused to enter the notch A by actuation of the starting handle 33. After a predetermined number of revolutions, the roller 46 strikes the rod 44 to rotate the shaft 32, until, under the momentum of the apparatus, the roller E is seated in the notch C. On further actuation of the shaft by the roller 47 the roller E moves into the notch B which is of such a shape that the momentum is overcome and further movement is prevented, whereby the machine is stopped.

Abstract: 933,289. Measuring radial play in bearings. SVENSKA KALLAGERFABRIKEN A.B. April 4, 1961 [Aug. 23, 1960], No. 12014/61. Class 106 (2). Apparatus for measuring the radial play in rolling bearings comprises a mandrel 2 on which bearing 1 is mounted with its inner race 3 held between a sleeve 4 and a pressure plate 5. The outer race 7 is rotated by frictional engagement between the side face of race 7 and an O ring 12 on a disc 8 driven by a belt 10. A load is applied successively to diametrically opposite sides of the bearing 1 by pairs of rollers 13, 14 on pneumatically operated pistons 15, 16. A pneumatic gauging nozzle 17 on arm 18 of a U bar 19 having a finger 21 contacting the inner race 3 detects movement of the outer race 7 to measure radial play. The rate of rotation of race 7 is chosen in relation to the inertia of gauge 17 so that imperfections in the shape of the outer race 7 do not affect the result. The race is released after gauging by retraction of pressure plate 5. A trough may be provided to supply the bearings to the gauging unit and a casing may be provided to displace the bearings from the trough after gauging. The apparatus may be adapted to sort bearings according to size.

Title: Improved method of and machine for gauging articles, especially glass tubes and the like
IPC: B07C5/07
Filed: 1933-04-28
Abstract: 398,457. Sorting-gauges. HADDAN, R., 31, Bedford Street, Strand, London.- (Corning Glass Works; Walnut Street, Corning, New York, U.S.A.) April 28, 1933, No. 12460. [Class 106 (ii).] In a machine for sorting fragile articles such as glass tubes, each article arriving before a gauge gap is urged to enter the gap by fluid pressure. The tubes 112 to be gauged are picked up from a conveyer 113 by fingers carried by chains 54 which carry them upwards until they encounter fingers 59 on conveyer chains 56, which advance them to the opposite end of the machine, the tubes on the return run being supported on tables 61, Fig. 5, while they are advanced by the fingers 59 towards the gauge-wheels 86, the movements of which are synchronized with the movements of the chains 56. Fluid pressure supplied through perforations 76 in the wall 74 of a chamber 71 forces upwards the tubes 112 into the slots 93 of the gauge-wheel, but if the tube is of greater diameter than the distance between the gauging point 95 and the opposite wall of the slot its displacement by the fluid pressure is prevented and the rejected tube is brought against a deflector 67 and discharged down a passage 113. A similar sorting operation takes place at the next gauge-wheel. Each gauge-wheel 86 may comprise an intermediate gauging disc 96 clamped between gauging discs 97, the discs being rotatably adjusted before clamping so as to adjust the gauging points. The number of perforations 76 in operation may be varied by sliding valves 77. In a modification, Fig. 9, the gauge-wheels are replaced by an adjustable lug 117 having a gauge point 119 co-operating with the upper end of the deflector 67<1>, the tubes 112 to he gauged being forced upwards by fluid pressure as before.

Title: Balancing synchros
IPC: G01M1/22
Filed: 1956-04-24
Abstract: 793,335. Poles for dynamo-electric machines. NORDEN KETAY CORPORATION. April 24,1956 [May 23, 1955No. 12467/56. Class 35. [Also in Group XXXVI] A synchro 50 is compared for accuracy of alignment with the setting of a master transmitter 10 by interconnecting the stators of the two devices, energizing the rotor 20 of the generator and positioning the rotor 46 of the synchro under test at 90 degrees to that of the generator, its dials 24 and 52 being used to indicate the angular position. Under these circumstances the output of rotor 46, as measured by voltmeter 60, should be zero. If it is not zero, rotation of either the generator rotor or the motor rotor will reduce the output voltage to zero. The direction of this rotation indicates that the resultant field due to the stator must be rotated in the opposite direction and this is done by measuring the permeability ahead of the rotor and decreasing it behind. The gap may be increased by honing the polepieces and decreased by upsetting the polepieces by resting them on an anvil and striking them with a hammer, This is done until half the error is removed. The rotor is then rotated through 180 degrees and the rest of the error removed on the opposite polepieces. An alternative method of reducing the effective air gap is to insert powdered high-permeability magnetic material in the slot adjacent the appropriate polepiece. The Specification then indicates that the generator rotor may be moved on and the motor rotor position of 90 degrees to it and the process repeated. Before the operations are commenced readings may be taken right around the synchro. If all the errors are in one direction the rotor may be drilled as at 71 and 73 and the holes filled with highly permeable material or left empty according to the necessary displacement of the effective rotor axis.
