Suecification of Letters Patent.
' Application filed 32117;- 28, 1910. Serial ZEc. ll
To all whom it may concern:
Be it known that I, Armin GABRIEL Ln Cnn'mmnn, a citizen of the French Republie, and resident of Marseille, France, have invented a certain new and useful Blowpipe, of which the following is a specification.
This invention has reference to a method of and means for regulating the feed Off the gases inblow-pipes.
. It has-been observed that in apparatus such as oxyhydrogen, oxy-acetylene or other blow'pipes in which one of the gases under a low pressure is-drawn along by means of an injector or some mixing device, owing to the pressure under which the other gas is used, the flame originally regulated to suit the work to be done deteriorates gradually as the blow-pipe becomes heated. If for example an oxy-acetylene blow-pipe be em ployed in which the acetylene procured by a generator is drawn along by a current of oxygen under pressure, it will be noticed that the flame which was properlyregu:
lated to commence with becomes graduallyoxidizing. This might be very detrimental to the quality of the work to be done, particularly in the case of the autogenous sol dering of iron and steel, the efiect of the oxidation being to reduce considerably the resistance of the metal to the soldering. The action of this phenomenon may be readily observed by heating at one point a pipe in which a gaseous current circulates fed from a reservoir whence the gas issues at a definite pressure; it will bejound that the volume of gas discharged goes on diminishing as the local heating. of the ,pipe is increased. It is as if the heating produced a resistance to the circulation of the gas, a resistance which may be compared to a counter-pressure which would have the same retarding eflect upon the flow of the gas. It is clear consequently that the distui'bing infiuenc'efof the heating will be so much the greater the smaller the original pressure at which the gas issues.' It follows that the heating of the body of the blowpipe will have its greatest retarding cheer on that gas which is admitted to it under the lowermost pressure, and consequently the relative proportion of the second s in the mixture will increase. in the c. oi the oxyacetylene blow-pipe for example the proportioirof acetylene will duninish more quickly than that of the i gen and the flame becomes oxidizing, already indicated above.
The object of the present 1'' *ntion is to remedy this defect and this recoil accomplished by utilizing the phenomenon itself of the resistance produced by the heating of the passage in which the gas cir culates. For this purpose all that is neces sary is to modify the course of *l' [1/ which leads the high pressure g mixing chamber-41hr; oxy the any-acetylene blow-p1 pipe receives a supplementz a certain portion of its len m by causing it to deviate so as to approach sufiic-iently the head of the blow-pipe.
The figure of the accompanying drawing shows this arrangement in elevation.
in this figure, 1 is the feed tube of the gas under low pressure (combustible gas) and 2 is the high pressure tube (for the oxygen) arranged as explained above. The correctness of the views which have led up to this method is demonstrated in another way by the fact that if the length of pipe submitted to the action of flame be increased unduly, the object in View. is over stepped, causing a derangement, the reverse of that which it is desired to obviate. By suitably regulating for each blow pipe the arrangement of the tube with a View to the heating of the high pressure gas, there will be no deterioration of the during the- 7 either in the one direction or in the other, zit which is so much the more importam. seeing that this deterioration when it takes place comes about gradually and esca o'es for some time the attention of the workman.
