[Also in Group XXX] An automatic-loading tyre press, with separable mould sections, has a transfer device mounted above the mould, which is operable to receive an uncured tyre band from a conveyer mechanism and to move the band into the lower mould section. The known press described has two moulds mounted side by side, the upper mould sections tilting back to give access to the lower mould sections. The transfer device 35 comprises an expanding chuck 42, having arcuate segments 43 to fit inside the tyre band, carried by a pair of arms 41 attached to a shaft 36 which can be rotated by a mechanism comprising a cylinder 39, pivotally carried by a guide plate 24 and having an extensible piston connected to a lever arm 40 keyed on the shaft 36. The frame of a conveyer mechanism 45, suitable for car tyres, is carried by upright guide plates 24, 24<SP>1</SP>, Fig. 4, (not shown), and includes span members having channels 52, 53 in which the rollers 63, 65 of a trolley, carrying a pan 60, run, means (69a) being provided for adjusting the height of the pan 60 to suit different tyre sizes. The trolley is connected to an endless chain 72 which passes over an idler pulley 73, a tension-maintaining sprocket 74, and finally around a drive sprocket 77, driven by a motor 79. In operation an uncured tyre band B is placed in the pan 60 at its lowest position, Fig. 1, the trolley structure then moving towards the apex of the span members where the tracks 52, 53 diverge permitting the roller 65 to move smoothly ahead of roller 63 so that the tyre band is in correct alignment with the transfer chuck 35. If the axis of the band B is slightly lower than that of the chuck 35 when the trolley approaches the chuck, the expanding action of the chuck 35 will lift the band B clear of the base of the pan 60. Electrical control switches may be provided to carry out the above operations in the correct sequence. The transfer device 35 carries the tyre band to a position above the lower mould section where the chuck contracts, releasing the band. A conveyer mechanism suitable for larger tyres, Fig. 7, incorporates a hoist 111 which lifts the tyre bands up to the span members 91 where rollers 116, 118 run on to an endless chain 105 which carries the tyre band pan 110 along the spans 91 to the transfer device 35.

Abstract: 275,946. Dap - Motor - Patent - Ges. Aug. 14, 1926, [Convention date]. Movable - abutment, type; working - fluid supply. - In a twostroke-cycle 'engine the mixture is compressed in a group into a condition ready for ignition and is so supplied to the working cylinder, the combustion products being exhausted by an ejector. As applied to a rotary engine the power and pump cylinders 1, 2, Fig. 2, alternate; the cylinders are carried by arms a. on the driving shaft and rotate continuously. The power pistons 3, are carried by arms b on a hub and move intermittently. Planet pinions c on the cylinder arms gear with a fixed wheel d and drive connecting rods h attached to the piston arms b ; the crank pins on to which the connecting rods are pivoted move through a circle of twice the radius of the pitch circle of the. planet pinions, in order that the pistons shall remain stationary during the power stroke and then follow up the cylinders at twice the rate of movement of the cylinders during the instroke of the pistons. A detent as described in Specification 267,401 is provided to ensure that the pistons shall remain stationary during the power stroke. The pump pistons 4 are connected to a second hub and follow up the cylinders but are not held fixed at the ends of the out-stroke. As shown in Fig. 1 each pump cylinder 2 draws mixture from a spray carburettor and delivers it past the pump valve 5 and cam-controlled valve 6 to the inlet valve 7; the pump piston, which may be of larger diameter than the power piston, has a lead over the power piston. The inlet valve 7 closes before the controlled valve 6 and thereby prevents back ignition in the piping. The exhaust is withdrawn through the terminal ports 10 by an ejector 12, the air for which is collected by scoops on the rotating cylinder block. The amount of opening of the valve 6 is variable by adjustment of the cam 13. Carried on the valve lever 14 is a. contact 29 which is included in the. ignition circuit and prevents ignition until the valve 6 is closed. Excess mixture is returned to the carburettor via the pipe 24 and variably loaded valve 8 this mixture passing through a choke tube surrounding the spray nozzle. Air to the carburettor is controlled by the throttle 17 and valve 20. A compression relief valve 28 is provided for use at starting.
