BLAST-FURNACE.
SPECIFICATION'forming part of. Letters Patent No. 282,512, dated August '7, 1883.
Application filed March 1, 1883. (No model.)
T aZZ whom it may concern Be it known that I, JAMES J. FRoNHmsER,
of Johnstown, in the county of Cambria and State of Pennsylvania, have invented certain Improvements in Blast-Furnaces, of which the following is a specification;
My invention consists in a method of introducing materials into a blast-furnace through the tuyeres without taking off the blast, which I accomplish by means of the apparatushere:
introduced through the tuyeres, or a cap on the end of the blow-pipe is removed and the pipe is filled with the material, so that it will be carried into the furnace after the blast is turned on. All of these manipulations, however, necessitatethrowing the blast off of the furnace before the material can be introduced,
and this has the disadvantage that just as soon as the blast pressure is removed cinder or metal is apt in-some parts of the furnace to run back' into the tuyeres, causing great loss. By my arrangement material can be fed into the furnace continuously without stopping the blast. Inthe drawings accompanying this application, Figure 1 is a vertical section of the improved apparatus embodying my invention.
Fig. 2 is an outside elevation of the same. Fig. 3 is a transverse view of the top. Fig. 4 shows the openings through which the materials are fed into the upper or hopper part of the apparatus.
Inthese figures the parts of the apparatus are indicated by letters as follows:
0 represents the hopper or receptacle for the material. B is the opening through which thematerial is introduced.
A isa valve closing the opening 13-, which valve. A is held in place by the clamp Y, furnished-witl1.bolt b and nut c at one end and bolt Z at the other end. Thevalve A is allowed to open by swinging to one side on the bolt 0.
E is a bell on the bottom of the cylinder or hopper O, and is manipulated by the rod and lever I, which are connected by the bolt N,
the lever I being fastened on the stand or fulcrum K by the bolt M, and is counterpoisedby the weight H.
F is a funnel-like extension of the hopper O, fastened to it by the flange V at the top, and fastened to the neck G by the flange and bolt V.
'J is the bustle-pipe, encircling the furnace above the tuyeres, the neck G entering it, as.
shown in Fig. 1.
Wis a pipe connected with the funnel F below. the valve E, and also connected with the hopper G at its top or above the valve E;
this pipe W being furnished with the cook or valve X.
The method of operating this charging apparatus is as follows: The nut c is taken off of the bolt 1), the clamp Y is removed, and the valve A is opened by swinging it to one side, when the material is charged through the valve A into the cylinder or hopper O. The valve A being then closed, and the valve E opened, the material by its own weight, if the pressure is not too great, will drop through the neck G into the bustle-pipe J and will be carried directly into the furnace with the blastair. In case the blast-pressure is too great against the valve E, and the weight of the material to be charged into the furnace is not suf ficient to overcome it, then the valve X in the pipe WV is opened, by which means the pressstored to equilibrium, and the material will drop through the valve E from its own weight.
The cylinder or hopper O can be made large enough to hold several hundred pounds of material, and by-adjusting the weight H on the lever l the size of the opening in the valve E for blowing fuels and other solid matter into a blastfurnace, and I do not claim such appaure above and below the valve E will. be re- 7 ratus, broadly; and I do not use gas or a mix- I poised'bell E, and-valve A, and the equilibrium ture of gas and other fuel, as my apparatus is I pipe W, constructed substantially as described, IO
designed for the use of solid fuel only. and for the purpose set forth.
Having thus fully described my invention, 1 5 what I claim, and desire to secure by Letters Patent, is WVitnesses:
In combination with the bustle pipe of a OYRUs ELDER, blast-furnace, the hopper O, funnel F, counter- JAMES M. SWAN K, J1.
