Title: Improvements in pavement heaters
IPC: E01C23/14
Filed: 1932-10-05
Abstract: 412,630. Road-surface heaters. HAZLEHURST, H. E., 23, Newton Court, Kensington, London. Oct. 5, 1932, No. 27670. [Class 107.] Relates to road - surface heating machines of the kind comprising a horizontal combustion-chamber having at one end a fuel-consuming device, and at the other end an outlet leading to an enlarged hood disposed near the road surface. According to the invention complete combustion is effected within the horizontal main combustionchamber by the turbulent mixing of secondary air with the products of partial combustion, the mixing being effected by means operating partially to obstruct and retard, but not to prevent, the flow of the main body of the combustion gases on their way to the outlet. In the form shown in Fig. 2, air from a fan 6 is supplied through a valve-controlled conduit 5 to an oil burner 1 which is arranged to project fuel into a combustion chamber 2 forming part of an outer main combustion chamber 3. The products of partial combustion are deflected upwardly by an abutment 9 and are thereby mixed with a body of secondary air supplied to chamber 3 by the fan 6. Complete combustion is thereby effected and the gases pass through a vertical conduit 13 to the hood 10, which may be provided with deflectors 11. In a modification, the chamber 2 is formed in the upper part of the chamber 3. In another construction, the combustion chamber 2, Fig. 6, comprises a separate tube 17 mounted within the enlarged end 20 of the chamber 3. A plurality of radially extending fins 18 serve to centralize the combustion-chamber within the casing 3, and provide also a plurality of passages for the secondary air supplied by the fan 6. Abutments 21 and 22 produce the required turbulent mixing of the products of combustion with the secondary air. Further modifications employing an oil burner are also described. In the modification shown in Fig. 12, solid fuel is burnt on a grate 39 to the underside of which air is supplied through a conduit 42 by a fan 6. The products of combustion are deflected upwards through an opening 47 to intermingle with a body of secondary air supplied to the chamber 3 above the upper wall of the combustion-chamber. Some of the secondary air is deflected downwards into the combustionchamber by upstanding abutments 45 disposed near ports or passages 46. The hood, in all cases, may be detachably mounted on the extension 13, and a jib crane is provided on the machine for lifting the hood onto and off a transporting platform. Specification 412,899 is referred to.

[Also in Group XXVIII] A coupling member 9 is movable in a rigid support 12 on presentation of the co-operating coupling member 1 and has hooks or claws 40 which are controlled by lever-and-spring mechanism so that on the continued presentation movement of the member 1, the claws engage behind an abutment 8 thereon and draw the members 1, 9 tightly together. Each claw 40 has a slot 44 comprising a longitudinal part 46 and an inclined part 48, in which slides a pin 16 secured on the support 12, and has a socket 42 which receives a rounded nose 35 constituting the shorter arm of a first-order lever 33. Each lever is pivoted on a ring 20 which may rotate about the body of the member 9 but cannot move otherwise thereon, and the longer lever arm 34 is urged by a spring 50 against a stop 52 on a chassis 15, to which the support 12 is secured. When the member 1 engages the member 9, the latter moves with it against the restoring spring 21 and causes the claws 40 to move along the pins 16, thereby bringing the claw-ends 41 behind the abutment 8 on the member 1. Further movement in the direction of presentation causes the levers 33 to pivot so that, the noses 35, by moving faster than the ring 20, bring the coupling-part 1 into firm locking engagement with the other part. The lever arms 34 are then moved away from the stops 52, the spring 50 being stressed further so as to maintain tight contact between the members 1, 9, Fig. 5. In a modification, Fig. 6, preferably for a wave-guide, the support 12 is box-shaped with a tubular slotted extension projecting from one wall 17 to support the coupling-member 9. The shorter lever arms are replaced by cranks 30 which engage the sockets 42 of the claws 40, the longer arms being controlled by helical springs 50.
