IMPROVED mrfl-iiwnome #URN/lcs.
Specification forming part of Letters Patent No. 56,919, dated August 7, 1866.
To all whom it mrtg] concern:
Be it known that I, JOSEPH FIELDHoUsE, of Taunton, in the county of Bristol and State of Massachusetts, have made a new `and use-v ful Improvement in what areusually termed Pipe-Welding Furnaces, or, in other Words, furnaces for heating a plate of iron to a temperature such as may be sufficient to enable its opposite edges to be welded together in order to convert the plate into a pipe; and I do hereby declare the said invention to be fully described in the following specification and represented in the accompanying drawings, of whih- `Figure l is an elevation of one side, and Fig. 2 an elevation ot' the other side, of the furnace. Fig. 3 is a horizontal section of it, such section being taken through the fuelsupply throats and the connecting-passages of the two chambers of the furnace. Figs. 4 and 5 are vertical and longitudinal sections taken through the said two chambers. Figs. 6 and 7 are end views, and Fig. 8 is a transverse section, of such furnace.
This furnace is a compound one-that is, it has one main and one auxiliary chamber of combustion, each chamber being provided with a separate grate. In this respect it does not differ from the ordinary pipe-welding furnace. The difference between the two is to `be found in the arrangement ofl the fuel-feeding throats, and in having bridges instead of a solid floor at the bottom of what is usually termed the overt In the common pipe-welding furnace there is a long chamber or oven directly over a fireplace or chamber of cumbustion, such oven being provided with a mouth at each of its ends or at one end only of them, the said mouth being for the purpose of introducing the skelp or blank into the oven for the purpose of being heated thereby before being introduced into the auxiliary or flame chamber,
where it receives its welding temperature. The chamber of combustion underneath the oven simply Served to heat the oven, and was provided with one or more fuel-supply throats or mouths. The supply of fuel to the other chamber has been by a series of throats in its outer side Wall. In consequence of so introducing the coal or fuel it was thrown 1n contact more or less with the pipes while in the act of being heated. rEhe result was a reduction of the temperature of the pipes as well as other evils not necessary to mention, except it be the filling or choking them more ory less With the coal.
In carrying out my invention, I arrange the fuel-supply throats for the welding-heat chamber in the partition-wall, between it and the oven, and directly opposite each of such throats I arrange another receivingthroat in the side wall of the oven lire-place, and, instead of making the same with a close bottom, I form it with `a series of bridges running across it, with openings between to extend from the fireplace into the oven. These bridges are for supporting the skelps or pipe-blanks while they may be in theact of being heated, preparatory to bein g introduced into the weldingheat chamber.
The fuel for supply of each furnaceor the grate thereof is to be thrown into and through the throats of the oven fire-place and upon the grate thereotgr-Where it is to be allowed to remain until it may become sufciently on re to be introduced into the welding-heat chamber. By having bridges instead of a close bottom to the oven the heat of the fuel below will be applied to better advantage to the skelps.` The liberated combustible gases will rush into the welding-heat chamberand be consumed therein, the spent flame and volatile products of combustion escaping from the said chamber byits end mouths, through which the skelp is introduced into the chamber for being heated to a Welding temperature.
With my improvement there is not only a very important saving of fuel, but the pipe skelps are heated to better advantage and with more celerity.
In the drawings, A is the oven; B, the tireplace underneath it; C C C, the bridges for supporting the skelps. D D D are the fuelsupply mouths on the side wall of the fireplace B. E is the grate of the oven nre-place,
and E the ash-pit thereof. a is the door, andb the skelp-entrance hole or mouth of the oven.
G is the partition-wall between the oven and the welding-heat chamber H, such wall being perforated with a series of throats, c c
c c, each of which is directly opposite some one of the mouths D D D, and, like that, has its bottom even or level with the upper surfaces 0i the tlrst of the two grates, E and the latter grate being` that of the welding-heat chamber. Each grate may be a revoluble one-that is, may be so applied to the tireplace as to be capable of being either revolved or turned down in order to discharge coals or clinkers when on it into the ash-pit below it, there being an ash-pit, K, beneath the grat-e I.
In the drawings, t a a2 t3 are the doors of the ash-pits, the oven, and Welding-heat chamber. L L are slides or covers to small key-chambers M M, into which the journals of the grates extend, each of such chambers bein g to allow a key to be applied to the gratejournal for the purpose of enabling a person to turn the grate as occasion may require.
I claim as my invention--h 1. The arrangement of the fuel-supply throats c c c c of the Welding-heat chamber in the par-y tition G, which separates it from the oven, and
y with respect to the fuel-supply throats D D D D JOSEPH FIELDHOUSE.
