Letters Patent lNo. 108,519, dated October 18, 1870.
IMPROVEMENT IN THE CONSTRUCTION, JOlNTLV, OF FlRE-BEDS AND TUYERES.
The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:
Be it known that we, PHILANDER ll. Roo'rs and FRANCIS M. ROOTS, ot' Connersville, in the county of Fayette and State of Indiana, have invented cer` made in a novel form, and together and entire.
Also, ot' a metallic tire-bed with a perforated bottom,and a pipe or vertical passage below said bottom, with a tuyere entering its side, and a gate pivote-d .to its lower end.
' i In the drawing- Figure l is a top-plan view; and
Figure 2 is va vertical cross-sectionon the line :if a: of iig. 1.
The object of this invention is to construct, in a strong and durable manner, a metal fire-bed and tuyere in a forni convenient for application and use in any place suitable for a blacksmiths or similar forge, as well as one that may be readily set up that will require no dressing, and willV secure an economical as well as thorough combustion ofthe fuel.
In constructing our tire-bed and tuyere, we cast the bed A, tnyere B, with the perforated bottom C, vertical passage d, for ashes and gas, and induction airpassage c, in one piece, and in the form clearly shown in both figures. v
The fire-bed A consists of a nest, or concave or curved recess,.with walls l) b', forming nearly two arcs of circles, and expanding ont as they rise into a plate,
a al, of a square, circular, or other shape, and so as to form a` part of the hearth of the forge. p
The bottom of the rire-bed is provided with perforations, C, which open into the vertical passage d of the tuyere B, to allow the ashes to fall into the passage d, which has pivoted to its under-side a gate or valve, D, at g, so as to turn horizontally and keep the passage closed when required, and so that it may be opened for the removal of the ashes when desired.
In place of a gate or valve an ordinary cap may be used. Then the valve is used, it should have a rod, E, connected to it, for convenience in operating it.
The induction-pipe oran-passage e, which is'cast solid with the llire-hed, is made slightly tapering inside, at the end which receives the pipe from the blower or the nozzle of a bellows, and is so connected that its opposite end opens into the passage d at its side, under the perforated bottom C.
lhe opposite sides of the top plate a. a', on opposite sides of the tire-bed, are made, when desired, with depressions j', so that, when the 'middle portion of va long piece or bar of iron isvto be heated it can be placed fairly, and to the best advantage, in the tire for that purpose. o
The hearth of the tire-bed, or that portion of it about the nest, isf shown in the drawing as square; but it is obvious that it may be circular or of any other desired forni.
As the induction-passage leading from t-he blower to the tuyere enters the vertical passage, through which the ashes fall, at right angles, it will be seen that it cannot be obstructed or interfered with bythe ashes.
In this way we produce a combined fire-bed and tnyere that may be readily set up iu a blacksmiths or similar forge, the lire-bed heilig made in the form or shape demonstrated by experiment to bcbest adapted for giving the best form to the re.
As the whole is cast in one piece, there is nothing to get out of order. As thereare no'joiuts, there is no waste of the blast by leakage, and hence the whole ofthe'blast is utilized and the best results secured.
lhe combination being` in one piece, it canbe readily taken ont and put in place, withoutdisturbing the other parts of the forge.
Having thus described our invent-ion,
lVhat we claim is- 1. A metallic fire-bed for forges, made in the form herein shown and described, for the purpose of giving shape or form to the body ofthe tire, as set forth.
2. A combined metallic fire-bed and tuyere for forges, when made in one entire piece, and in the form herein shown and described.
3. The fire-bed A, witlrits perforated bottom c, tuyere B, and vertical passage (1'all made in one entire piece, with gate 1),.pivoted at the lower end of the passage d, the whole constructed and arranged as shown and described, and for the purposes set forth.
