Filed: 1938-11-09
Abstract: 521,015. Preheating burners. CLEVELAND, F. J. (Ehrich & Graetz Akt.-Ges.). Nov 9, 1938, No. 32541. [Class 75 (i)] Fuel is fed to the preheating burner of a vapour-burning illuminating or heating apparatus through the annular channel between a tube 5, Fig. 1, and a pin 7, the length of the tube 5 being at least 50 times the diameter of a circular channel equal in area to the annular channel. The pin 7 is hooked at its lower end and may be bent at intervals along its length to grip the tube 5. Air is supplied from the fuel reservoir to mix with the fuel through an annular channel between parts 3, 4 carrying the tube 5 and a conical passage 8 between the part 4 and valve body 9 which carries the flame tube 12. In another construction the annular fuel channel is formed between the fuel tube and a pin having its end coned to act as a valve. The pin is loosely secured to an operating spindle. The pin or the tube may be coarsely threaded. In another construction shown in Fig. 5 in which the burner is arranged beneath the fuel reservoir the pin 7c is carried by a valve spindle 10a formed with grooves 20 and the fuel tube 5b is threaded in a body 3b formed with fuel and air supply passages. When the valve spindle is turned the fuel and air passages are opened or closed successively.

Elongated articles, which are suspended from a conveyer moving in a sinuous path, are maintained in predetermined orientation. A series of bars 64, Fig. 2, which support the articles P, are suspended from the chain by pins 68. The lower end of each pin carries a disc 76, Fig. 3, which has a rib 78 formed on its upper surface. Each rib co-operates with a pair of corresponding depressions 72, 74 formed in the bottom of a circular extension 70 of the bar. The direction of movement of the chain is changed by passing it round a sprocket 90, the shaft 92 of which is connected to a shaft 98 by gears 94, 96 of equal ratio. The shaft 98 carries a bar 100 from which depends a roller 102. This roller prevents rotation of the bar 64. In a modification, Fig. 5, guide members 110, 112 co-operate with the bars 64 to maintain their orientation.
