J. S. WILLWAY & SONS, St. Augustine’s, BRISTOL. THE “INJECTOR” MIXED JET.
(JACKSON’S PATENT). PRICE SOs. = |
HIS is the only Mixed Gas Jet which will work at full power with coal gas taken direct from the town supply, and oxygen from a cylinder. In order to effect this the oxygen, on its way to the mixing chamber, is made to pass through the small Injector | in the sketch at a pressure of about 12 lbs. per square inch. In passing through the Injector it sucks a supply of coal gas from the pipe H, which is connected with the house pipe, and forces it forward through the short pipe T into the mixing chamber M. Here the mixed gases meet the baffle plate B, which has the two-fold effect of silencing the passage of the gases, and ensuring their complete admixture. The mixed gases then pass through holes in the edge of the plate,’ and so to the burner. The requisite pressure of oxygen is obtained in the ordinary way by a fine tap on the cylinder, or an automatc regulator fitted with a high-pressure spring to deliver at about 15 lbs. pressure. k The superiority of this Jet over all others remains fully established. It will yield THE FULL 1,800 TO Xi, 2,000 CANDLE-POWER (so-called) of the ordinary mixed jet when taking its supply of coal gas direct from the town’s pipe, or even from a bag without any pressure at ali. \fa town’s supply is rot available, it will work just as well with coal gas from a cylinder. We cannot see why ordinary mixed jets should be purchased which cannot offer these alternatives. As for blow-through jets, ejector or otherwise, we do not know why they should be used at all, when with the same economy and convenience of working, the Injector Jet will give two or three times the light. By re-moving the Injector nipple the jet becomes an ordinary mixed jet. This can be done whenever it is desired to work with oxygen at low pressure, and coal gas from a cylinder. :
The working of the Jet is simpler than that of an ordinary jet. be touched again when using towns gas... The turning off or on of the oxygen supply regulates automatically the supply of coal gas. This is a great convenience in actual use.
Most existing jets can be fitted with an Injector to enable them to take their coal gas supply from the house pipe.
When the H tap is once adjusted, it does not need to
The Jet will in certain cases be sent on approval on deposit of purchase price. Further particulars free on application to MANCHESTER OXYGEN (Brin’s Patent) CoO., LTD., GREAT MARLBOROUGH STREET, MANCHESTER.
