Title: Tire chuck
IPC: B29D30/00
Filed: 1960-03-01
Abstract: 921,642. Tyre-supporting chucks. FIRWOOD MANUFACTURING CO. Ltd. March 1, 1960 [March 6, 1959], No. 7262/60. Class 144 (1). For inflatably supporting a tyre during cooling after moulding, or for grinding, buffing or thump-testing operations, a chuck comprises two members 10, 14, each carrying a tyre bead supporting ring 18, 20 respectively, one member (14) having a series of pivoted latch members 34 operable by a fluid pressure-operated piston 46, 48, 50 to engage a conical surface 42 of the other member (10) to hold the members in tyre-supporting relation. As shown, the members 14, 10 are disposed to support the tyre horizontally, the member 14 being fixed above the member 10 which is movable vertically towards and away from the member 14. The member 14 comprises a central cylindrical body portion 38 in the lower end of which the latch members 34 are pivoted to extend radially of the portion 38 with their radially inner ends slotted to engage the rim of an actuating member 46. The member 46 is carried at the end of a piston rod 48 of a piston 50 movable in a cylinder 52 formed in the portion 38, the piston being biased downwardly by a spring 62 and having an upwardlyextending rod 70 to project through a cap 58 closing the cylinder 52. Pressure fluid is fed into the lower end of the cylinder 52 through passages 66, 68 in the portion 38. In operation, with the cylinder 52 unpressurized, the piston 50 is spring-urged to its lowest position to move the latch members to a horizontal disposition where their outer ends lie flush with the periphery of the portion 38. The rod 70 lies within the cap 58. A tyre is supported by one bead on the ring 18 of the chuck member 10 which is then raised vertically so that the portion 38 of the member 14 telescopes with a hollow cylindrical hub of the member 10, and the other tyre bead seats on the ring 20, the two rings 18, 20 having interfitting convex and concave surfaces 30, 32, respectively. Pressure fluid is then admitted to the cylinder 52 to raise the piston 50 and thereby rotate the latch members 34 so that the corners 40 thereof project radially outwardly to engage behind a conical surface 42 provided at the mouth of the hub of member 10. The rod 70 now projects from the cap 58 to indicate that the chuck members are locked together. The tyre is then inflated through ducts 72, 74 in the member 14, and the inflation pressure tends to urge the chuck members apart, whereupon the sloping surfaces 42 act on the latch members 34 tending to rotate them still further into locking engagement with the surfaces 42. In a modified arrangement the ring 20 is carried by a hollow axle forming the cylinder 52 which is rotatably mounted in a fixed portion of the member 14 and chain-driven to effect rotation of the tyre if desired, the member 10 being also rotatably mounted.

Filed: 1942-05-29
Abstract: 557,709. Automatic control systems for electricity supply. STANDARD TELEPHONES & CABLES, Ltd., and HOUGHTON, L. W. May 29, 1942, No. 7301. [Class 38 (iv)] Current to a load L is maintained constant by two indirectly heated thermistors T1, T2, i.e. temperature - responsive resistances having a high resistance - temperature coefficient. The load circuit includes in series the heating element r2 of one thermistor and the resistance element R1 of the other and the remaining elements r1, R2 are supplied in parallel or in series from an independent source S preferably of constant voltage. The change in temperature of resistance R2 resulting from a small change in current varies the heating of the resistance R1 to compensate the change in current. Positive or negative temperature coefficient thermistor may be used and the thermistors R1, R2 need not be alike in this respect. Both may be arranged in the same envelope.

Abstract: 674,672. Igniting burners. DRU JAARSMA N.V., and THOMEE, A. L. March 23, 1950, No. 7356/50. Class 75(iii) Lighting means for a balanced flue gas heater permitting the latter to be lit while it is sealed from the room in which it is fitted, comprises as an assembly an incandescent body gas tightly secured in the wall of the heater, heating means sealed from the interior space of the heater proper and so constructed and related to the incandescent body as to be capable of bringing the latter to sufficiently high glow temperature to ignite the gas fuel of the heater, and within the heater proper a pilot burner adapted to be lit directly or indirectly by the incandescent body and adapted to light the main burner(s). Fig. 2 shows a lighting means in which theincandescent body comprises a thin dishshaped sheet 11 of stainless steel mounted in the wall 1 of the heater and heated by a Bunsen burner 16 disposed externally of the wall 1. As soon as the disc 11 glows sufficiently a pilot burner 7 within the heater casing is ignited, the jet at the right (as seen in Fig. 2) being first lit, and the flame travelling through the combustible gas emitted from an incision or small holes in the side of the pilot burner tube to ignite a jet directed towards the left which ignites the main burners 3, the latter being sufficiently close to ignite one another. The required sequence of gas supplies is provided by a cock 15. A diffusing screen 18, perforated or otherwise, is interposed between the pilot burner 7 and the disc 11 in order to avoid cooling of the latter by the gas jet from the burner 7 before the latter can be ignited. The dish-shaped body 11 may be replaced by a tube extending outwardly from the wall 1 and closed at its outer end, the tube being heated by a burner placed beneath it. Alternatively the incandescent body may be in the form of a tube projecting into the interior of the heater and closed at its inner end, and an electric heating element may be disposed in the tube for heating the latter to the required igniting temperature. Fig. 1 shows a known balanced flue heater comprising a tube H for admitting combustion air from a point outside a building to gas burners N arranged at the bottom of a chamber F, the products of combustion passing to the outside of the building through a tube I passing co-axially through the tube K. The heater is contained in a flat rectangular box D the interior of which is sealed from the room in which it is fitted and has an outer jacket A having top and bottom openings B, C. Specification 645,582 is referred to.

[Classes 83 (ii) and 83 (iv)] [Also in Group XXXVI] Altering structure by mechanical treatment.- A straining clamp for an overhead cable 12 comprises a shoe 1 of U-section having an arched central channel 5, Fig. 2, in which the cable is clamped by a clamping member 3 secured to the shoe by U-bolts 4. The clamp is supported by links 2, Fig. 5, which pass through slots 8 in the shoe disposed between the channel 5 and the side walls of the shoe, as shown in Fig. 3, the links being pivotally connected to the shoe by a bolt which passes through holes 11, Fig. 1, in the side walls of the shoe. The end portion of the shoe in which the slots 8 are provided is bent through a right angle, as shown in Figs. 1 and 5, and is of reduced width so that the side walls of the shoe serve as side supports for the link 2. The shoe is pressed from a heated metal blank, the central channel 5 being first forged out and the edges of the plate then being bent up to form the side walls of the shoe. When cool, the end of the shoe is bent through a rightangle, pressure being simultaneously applied on the portions of the side walls of the shoe at which bending takes place so as to reduce the width of this portion of the shoe and increase the depth of its side walls. The material is bent cold to increase the strength of the bend. The slots 8 are then forged out, their lower edges 9 being subsequently subjected to axial compression to increase the thickness and hardness of the metal at these points against which the links 2 bear.
