Description
le W Q e' f @timed ADAM HERBIG, OF CORRY, PENNSYLVANIA, ASSIGNOR 'IO I-IIMSELF AND THMAS BLACKBURN, OF SAME PLACE. Letters Patent No. 84,059, dated November 17, 1868.
t IMPROVED TUYERE.
The Schedule referred to in these Letters Patent and making part of the same:
To all whom it may concern:
Be it known that I, ADAM Hannie, of Corry, in the State of Pennsylvania, have invented a new and useful Improvement in Tuyere-Irons and I do hereby declare that the following is a full, clear, and exact description .of the same, reference being had to the accompanying drawings, and letters of reference marked thereon, makingla part of this specication, in which- `Figure l is a plan view,
Figure 2, a longitudinal vertical section, and
Figure 3, a side elevation, ofthe upper disk detached, with the damper separated from it.
`This invention consistsin applying to the ducksnest of a tuyere-iron` for blacksmiths forges, an arrangement whereby the same may be conveniently blown out, in order to dislodge the debris which always collects therein.
To enable those skilled in the art to make and use my invention, I now proceed to describe its construction and operation.
' Similar" letters, iu the drawings, refer to like parts.
In the drawings, A represents `what is frequently termed by blacksmiths a ducksnest,.tl1e same consisting of two metallicv disks, a u', ofa size to suit the forge where itis employed, said disks being placed horizontally in the forge.
A metallic ilange, a, projects upward from the rim of the lower disk, a', which flange sustains, -upon its upper edge, the upper disk, a.
The two disks are connected by vertical bolts, passing through lugs b, two on each disk, projecting iirom opposite points in each.
lhe upper disk is removable from the flange. Said upper. disk is provided with a concentric basin, c, occupying its centralportlon, and projecting nearly down to the lower disk, said basin being provided, at its upper edge, with a damper, c', for regulating the draught. In all this I do not claim that there is anything new;
Opening liorizontallyinto one side of the flange a is a pipe, d, through which passes the air from the bellows to fan the llame.
It should be understood that the re is kindled in the basin c, and'that the blast passes through the damper c.
Opening into the flange a", at a point directly opposite the mouth of pipe d, is the pipe nl', of similar dimensions, The function of the pipe d is to form a way of exit for debris.
When the interior of the ducks-nest becomes choked up with cinders, and it is found desirable to remove the same, let the damper 0' be closed, and the plug that is kept in the outer end of the pipe d be removed. The full force of the bellows may then be exerted to drive all accumulations out through the pipe d.
I am well aware that both slides and valves in the bottoms of ducksnests have been used for withdrawing debris from tuyeres, but not, so far as I amaware, in connection with a blast. It is obvious, moreover, that the corners on each sideof such a slide can be but imperfectly cleansed in this way.
It will be seen that there is no part of Vmy ducksnest where dirt can effect alodgxnent against the blast, as the pipe el opens out of a curved surface, directly opposite the inlet-pipe, and itsv bottom is on a level with the disk a; The current has, therefore, full sweep, and, as has been found `by actual trial, m'ost eli'ectually removes the debris.
Having thus described my invention,
What I claim as new, and desire to secure by Let-i ters Patent, is-
The circular ducks-nest A, provided with the inletpipe d and the outlet-pipe d', placed opposite each other, and with the damper c', all arranged and operating substantially as described.
' ADAM HERBIG.
