UNITED STATES PATENT FFICE.
JOHN NELSON, OF OSWEGO, NEW YORK, ASSIGNOR TO HIMSELF AND ROBERT T. MORROW, OF SAME PLACE.
IMPROVEMENT IN TUVERE-IRONS.
Specification forming part of Letters Patent No. 121,189, dated November 21, 1871.
To all whom it may concern.-
Be it known that I, JOHN NELSON, of Oswego, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Tuyere-Iron and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon which form a part of this specification.
The nature of my invention consists in the construction and arrangement of a tuyereiron, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its con struction and operation, referring to the annexed drawing, in which Figure 1 is a longitudinal vertical section of my tuyere-iron. Fig. 2 is a side view, and Fig. 3 a section, both enlarged, of the ball in said tuyere.
A represents a cast-iron box or win d-chest, into which is conducted the wind from the fan or bellows through the tube B. In this box is placed a ball, (J, provided or pierced with different-sized holes for the different kinds of work, as follows: a a a and a are four round holes of different sizes, through one of which the wind escapes to b b are four round holes of equal size near the neck of the ball, and which, with the large round hole (I opposite the neck, are to allow the wind to go freely into the ball. This ball is pressed up to a hole in the top D of the tuyere, which formsthe bottom of the fire, by a spring, E, thus forming an air-tight joint, and allows the ball to be turned by a crank, G, at the outside of the forge, to bring to bear on the fire any one of the holes a a? a a best suited to the work. This can be done at any time without disturbing the fire; or, by a few entire revolutions, the fire can be cleared of cinders and dirt, which will fall into the wind-chest A below, and can be removed by a slide, H, at the bottom.
The advantages of this tuyere are numerous, but the most important are as follows: Economy in time and fuel, which is, owing to its perfect adaptation to all kinds of work and the cleanli ness in which a fire can be kept, without the loss of time and fuel incident to the usual method of clearing it; producing a sharp, compact fire, and more manageable than the tuyeres now generally in use; durability, for, when properly l ed in the forge, it is as durable as the forge it lf. It does not heat, and therefore the adhesion of clinkers is prevented, and the parts are not damaged. The communication between the fire and the bellows can be entirely closed, thereby preventing the accumulation of gas in the bellows.
I am aware that hollow perforated ball-valves for forges are not new, and also that solid ballvalves for forges, and a spring support combined therewith to hold the ball firmly in the cavity of the hearth-plate, are not new, and I disclaim both of these inventions; but
I claim as my improvement- The combination, with the hollow ball-Valve 0, having the two series of apertures and the supporting axle and crank G, of the spring or yielding support E, all constructed and arranged as set forth.
In testimony that I claim the foregoing as my own I affix my signature in presence of two wit- JOHN NELSON.
