Abstract: 376,815. Exhaust silencers. HEATHER, F., 38, Greenford Road, Sudbury Hill, Harrow, Middlesex. April 14, 1931, No. 11031. [Class 7 (ii).] The silencer, which may be used for induced or exhausted gaseous currents, consists of a nest of tubes a .. d of progressively increasing transverse dimensions, each tube being secured to and eccentrically arranged within a tube of - larger dimensions. Each tube has an opening or series of openings m . . p so arranged that the gas entering the inner tube a flows in a unidirectional and roughly spiral path to the outlet openings p over which a deflector q is arranged. The tubes are secured to one another, and the covers r, h to the outer tube d, by welding, but riveting or bolting may be adopted. A deflecting cone prevents the gases impinging on the cover h. In a modification, the tube d is replaced by a casing having an axial outlet. In a further modifica- ,tion, Fig. 4, two such silencers v, ware enclosed in a casing 6, the inner ends of the tubes being separated by a partition 5. Gases entering tube 1 flow outwardly through silencer v and inwardly through silencer w and issue through the smallest tube 4 thereof. In a still further .modification the construction is similar to that shown in Fig. 4, but gases enter each of the smaller tubes axially, flow outwardly, and are discharged through an outlet in one of the end covers.

Title: An improved means or mechanism for bringing to a standstill runaway tubs or wagons
IPC: B61K7/22
Filed: 1930-04-08
Abstract: 350,127. Stopping runaway wagons &c. LESTER, A., Stanleigh Road, Overseal, near Burton-on-Trent. April 8, 1930, No. 11087. [Class 104 (ii).] Mechanism for stopping tubs or wagons in mines &c. when they exceed a certain speed comprises two balanced levers having three arms 10a, 10b, 10c, the arms 10a being maintained in vertical position by the weight of the arms 10c. The levers are keyed on a shaft 7 mounted in eccentric bushes 6 which are rotatable in bearings on the sides of a frame 5 fixed between the rails. The arms 10b of the levers are connected by a rod 11 arranged below a pair of hooked arms 8 loosely mounted on the shaft 7. If the speed of the wagons is normal, the arms 10a are rocked only slightly, so that the rod 11 does not touch the arms 8. If the speed is excessive, the arms 10a are moved sufficiently to cause the rod 11 to throw the arms 8 up into position to engage the back axle of the wagon. Stops 17 carried by a shaft 16 support the arms 8 in their effective position. To release the wagon, the shaft 16 is turned by a key to remove the stops 17 from the arms 8, which then fall below the level of the axle. One of the moving members may operate a signal device to indicate the stopping of a wagon

Abstract: 452,322. Induction machines. KEITH & BLACKMAN CO., Ltd., J., and KEITH, G., 27, Farringdon Avenue, London. April 11, 1935, No. 11205. [Class 35] The brush carried by the rotor of an induction motor is lifted by a speed responsive member but the brush itself is unresponsive to centrifugal force. In the form shown, the speed responsive plate 10 has a hole for the passage of the shaft 4 and is pivoted at 11 on a plate 5 rotatable with the rotor in such manner that it moves to the right as the speed rises and its projection 13 strikes the brush carrying lever 6 and raises the brush 1 from slip ring 8. The lever 6 is pivoted at 3 and carries a counterweight 7 so that centrifugal force does not influence the brush. A modified form is described for a brush co-operating with a pair of slip rings in a common radial plane. The brush movement interrupts the auxiliary starting winding circuit.

Abstract: 723,353. Friction gearing. TEXTIMA SPINNEREIMASCHINENBAU CHEMNITZ VEB. May 5, 1952, No. 11311/52. Class 80 (1) [Also in Group IX] In a spindle drive for textile spinning, twisting and like machines, the drive train comprises intermeshing gear wheels, more particularly helical gear wheels and a friction drive connection characterized in that the friction drive consists of a pair of friction wheels arranged as an intermediate gear, said friction wheels being spatially separable from one another to effect stoppage of the drive to the spindle. As shown, a spindle 1 is supported in a housing 4 and has attached thereto a spiral worm gear 5 which meshes with a wheel 6 on a shaft 7. At each end of the shaft 7 is mounted a friction wheel 8 contacting friction wheels 9 fixed to driving shaft 10. The housing 4 can be adjusted vertically relative to a guide bar 12 rockably supported in a holder 26 secured on a bearing block 13 by bolt 28, block 13 being clamped to a rod 15. A spring 16 draws the housing 4 downwards and keeps the friction wheels in contact and a handle 19 is provided for lifting the housing 4 and so disconnecting the friction drive. To bring the spindle to rest after disconnection of the friction drive, a brake lining 24 is provided on the flange 22 of bobbin 23, which brake lining contacts the inside of the housing wall 21 enclosing the drive mechanism, when housing 4 is raised. In a second embodiment the drive from the main shaft to the intermediate shaft is via toothed gearing and from the intermediate shaft to the spindle by friction gearing, eccentric bushes being provided for disconnecting the friction drive.

Title: Method of bending metal tubes

Abstract: 801,470. Bending tubes. GRESSE, A., April 13, 1956 [April 19, 1955], No. 11371/56 Classes 83 (2) and 83 (4). A method of bending a tube comprises, first, bending the tube in a direction opposite that of the final bend, then bending the thus bent tube back in a direction opposite the first bend and then applying pressure to the inside of the thus partly-formed bend to move the tube between two spaced members to cause the limbs of the tube to move towards one another to form the final bend. A tube 1, preferably heated over the zone 5 to form the inside of the first bend, is bent over a former 2 so that the inside wall 3 becomes thickened. The thus bent tube is then bent back in the opposite direction, over a bending sheave 6 to form an angle of about 110 to 120 degrees. The inner wall 7 is thus thickened. An internal tube support 8 may be used. The bending sheave 6 has a semi-oval groove 6<SP>1</SP> to allow the thickened part 7 of the tube to move into the base thereof. After applying rapid heat to the inner region o, x, y, the legs of the bend are closed parallel to one another by movement of pivoted guide blocks 14, 15 together, and then by a suitably shaped member 18 which pushes the tube between the pivoted guide blocks 14, 15 and rollers 11, 12. Cooling liquid is supplied to the outer part of the elbow during this latter operation. The bent tube may then be formed in a die.
