PATENT OFFICE.
rTUYEE sTocx.
` Application mea July 7,
To @ZZ whom t mag/foonoef/m.'
VBe itknown that I, STANLEY R. GREENE, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Tuyre Stock, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applylng that principle, so as to distinguish it from other inventions.
My'invention relates to tuyre stocks and particularly to tuyere stocks intended for use in hot blastfurnaces. A
The annexed drawing and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of the various mechanical forms in which the principleof the invention may be applied.
In said annexed drawing: l
Figure 1 represents a central longitudinal section of my new and improved tuyre stock in connection with the blow pipe and a fragmentary portion of the water-j acketed tu re;
*igure 2 represents a View similar to Figure l, upon an enlarged' scale, of an improved elbow section yof tuyre stock forming my invention, showing a fragmentary section of a straight section of stock connected thereto; and
Figure 3 represents a side elevation of the parts shown in Figure 2. Y
Referring to the annexed drawing, there is disclosed a tuyere stock consisting of a section 1 adapted to be connected to the bustle pipe, not shown, and a section 2 adapted to be connected to the blow pipe 3. A fragmentary section of the usual waterj acketed tuyre is indicated by the ordinal 4. The adjacent machined ends of the sections 1 and 2 are so connected as to allow for swivel or rotary motion between said sections and the same are held to proper contact by .means of the eye bolts 5 and related parts, as plainly shown in the drawing. The adjacent machined ends of section 2 and the blow pipe 3 are removably held to the proper contact by means of the s ring-- held rod 6, as also plainly shown 1n the drawing. All of the above is well known practice, as known to those skilledin the art.
My invention consists in providing an unlined elbow section 2 for use in a hot blast v Specification of Letters Patent. Patentgd Feb,V 7, 1922 1919. sealNoJsoaase A y furnace, said section being comprised of cast steel. Furthermore, my invention consists in providing such a section of comparatively short length which, in combination with the unlined feature thereof, provides such a section of tuyre stock which is very light and very easily handled, more easily adjusted to the joints, etc. Furthermore, such a short length of the elbow section, together with the curve which I have given to the same, enables the elbow to be thoroughl and readily cleaned, inasmuch as from t e top thereof, by means of a straight poker, the accumulation at the bottom can be forced directly out of the lower open end.
I have further provided an eye-sight opening of improved construction. Said improvement consists in forming this opening 7 of much smaller diameter than has heretofore been utilized and locating this opening upon the curved back ofthe elbow section 2 and not substantially in the plane of the bottom of said section, so that the draft traveling around the curve tends to keep the opening clear from dust, etc. Heretofore this eye-sight opening has been of a size substantially the full diameter of the elbow section.
I have found it unnecessary to line the cast steel section because of its greater elasticity. The results in reducing the weights of the section are very noticeable. For instance, a lined cast iron section of normal sizewould weigh from six hundred (600) to eight hundred (800) pounds; a very light lined cast iron section would weigh as much as four hundred (400) pounds. The normal weight for my unlined cast steel section is two hundred (200) pounds.
What I claim is:
1. In a hot blast furnace tuyre stock; ar
blow pipe section leading into the furnace; a pipe section independently supported at an angle thereto and adapted to be connected to the bustle pipe; and an associated short unlined elbow section curved substantially from end to end adapted to be removably supported between said pipe sections in engagement with the ends thereof.
2. In a hot blast furnace tuyre stock, the combination with a straight section thereof, terminating adjacent the furnace opening and angularly disposed with respect to the axis of said o ning; of an associated unlined cast stee elbow section adapted to be in which substantially the Whole of the el- V .bQW- bottom dies in vplanes intersectingzthe elbow top and not intersecting Vthe vertical side Walls of the elbow, whereby accumulations at the bottom lcan be Yforced directly jfrom the Vtop'outof the lowerend.
4; In a furnace tuyre stock, the combination ol' :L straight Vpipe section, terminating adjacent the furnace opening; of a vcurved elbowsection connected etone end V-to said pipeA .section lund having its other end in alineinent with said opening and provided `ein Vthe curved back thereof, with it relatively Aminute peep opening in alinement with the furnace opening, said opening being unobstructed topermit of a continuous loW of air therethrough.
Signed by me, this lthiday of.June1919.
