PORTABLE FORGE.
SPECIFICA'FION forming partof Letters Patent No. 297,494, dated April 22, 1884.
` Application [ilcd June 23, 1883. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS H. BULLoox, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Portable Forges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
My invention relates to improvements in portable forges; and it consists of certain features of construction and in the combination of parts hereinafter described, and pointed out in the claims. i
In the drawings, Figure l is a vertical sectional View of ka portable forge with my improvements attached. Fig. 2 is a cross-section on the line ofx x, Fig. l, showing a top View of the bellows.
A represents the tray or pan of a portable forge supported by the legs a, that also support the bellows B, consisting of the top part, '1), and the lower part, b', and divided by the partition b2. The bottom of the bellows and the partition b2 are each provided with a clapvalve, c, preferably of the kind known as Smiths Flexible Valve,77 opening upward.
C is a ring, preferably of metal, and concentric with the top of the bellows, so as to balance the same. This ring may be of any desired weight, according to the pressure ofthe blast required.
D is an air-tube, extending from the inside of the top part of the bellows to the tuyere E, and acts also as a guide for the bellows, the latter being provided with the thixnble d, embracing the tube and sliding thereon.
F is a lever, connected by a wire to the lower part of the bellows, as shown, and operated in the usual manner.
The bellows operates in the usual manner,l except the toppart does not tilt, but rises perpendicularly, and is guided by means of the thimble d, sliding on the tube D, the ring of weight C in the meantime balancing the top part ofthe bellows, so that there is little fric- A tion between the parts D and d.
In Fig, 1 is shown a modification, in which the tuyere is at one side of the nre-pan, that necessitates an elbow in the tube D. Usually these forges are made with the tuyere in the center ofthe treepan, so that the tube D passes in at the bottom of the tuyere without any crook or elbow, making a shorter passage-way for the blast than forges of anyconstruction heretofore i'n use.
Vhat l claim isl. The combination, with a tray and bellows, or" an intermediate connecting-pipe rigidly secured at one end to the tray or tuyere,
and adapted to form a guide for the bellows, substantially as set forth.
2. The combination, with a tray provided with a tuyere and a bellows, the latter being THOMAS H. BULLOCK.
