JOI-IN VANES, OF BRAZIL, INDIANA.

BOILER-FRONT.

SPECIFICATION forming part of Letters Patent No. 673,101. dated April 30, 1901.

Application filed October 3, 1900. Serial No. 31,917. (No model.)

To all whom, t may concernI Be it known that I, JOHN VANEs, a citizen of the United States, residing at Brazil, in the county of Clay and State of Indiana, have in- Vented certain new and useful Improvements in Boiler-Fronts; 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 appertains to make and use the same. A

My invention relates to improvements in steel or wrought-iron boiler-fronts, and is more especially adapted to stationary boilers or steam-generators.

The object of my invention is to produce a boiler-front which is lighter, cheaper, and more durable than those now in general use; also, one that will not warp or crack, while at the same time it is very ornamental; also, to compensate for the contraction and eXpansion in a very simple manner; furthermore, which can be quickly set up in place, as well as taken down, and finally can be produced of thinner material than heretofore employed and still be stronger than the ordinary castiron fronts. v Y

With these objects in View my invention consists of a boiler-front rolled out of one, two, or more pieces or parts bolted together and provided with beads or molding, thereby strengthening it and making it ornamental; also, to produce an expansion-joint in the front to compensate for expansion and contraction, and linally it consists in certain details of construction and novel arrangement of parts, as will be more fully described hereinafter and specifically pointed out in the claims, reference being had to the accompanying drawings, in which- Figure l represents a front elevation of my improved boiler-front. Fig. 2 is a cross-section on line a; of Fig. 1. Figs. 3 and 4 are detail views of a modified form of expansionjoint. Fig. 5 is a view of the expansion-joint on an enlarged scale. l

In the drawings, A represents the main part of the front, made in this instance in two parts, which are united by an expansion-joint B and bolted or riveted together. Each side of the frontis stiened, as well as ornamented, by means of a bead E, and around the circular opening for the end of the boiler is arranged another bead d, having like functions as bead E. The fire-doors D and the ash-pit doors C are also made of wrought-iron or steel. The openings in the front for said doors are curved inward around their edges, as shown at c c, stiffening them, while at the same time strengthening the front. AThe holes for the bolts employed tovhold Vthe parts together may be slotted, as shown in Fig. 5 at c e, to allow the partsv to crawl, when they are expanded o r contracted by different degrees of temperature. On each side of the front is arranged a bead or molding E E, which serves to ornament, stiften, and strengthen thefront. If desired, lead or asbestos packing or its equivalents may be employed between the edges of the expansion-joint and the front to form a perfectly-tight joint. If desired, two eXpansion-joints B B may be employed, one on the inside and one on the outside of the front, although I desire to use the joint shown in Fig. 4. The lng b, forming the lower or bearing part of the hinges, may be provided with studs that pass through the front and are secured on the inside by a nut or rivet.

An ornamental cornice may be secured to the top of the boiler front, also made of wrought-iron or steel, to impart a finish to it, and by adding smoke-box doors to the extension a full or iiush front can be made.

I am aware that broadly expansion-joints are old and have been used in steam, hot-water, and other pipes, as well'as-for other purposes; also, that sliding joints in boilers are old, but never in connection with a boilerfront, and I therefore do not claim such broadly; but,

Having thus described my invention, .what

yI claim as new, and desire to secure by Letters Patent, is-

1. A boiler-front made of wrought-iron or steel, provided with an expansion-joint B, the beads E, E, at the sides and the bead d around the opening for the boiler, as shown and specifled.

2. A boiler-front made of wrought-iron or steel, provided with an expansion-joint, the pension-bead at each side, as and for the purbeads E, E, at the sides, the bead d around pose set forth. 1o the boiler-opening, and the openings for the In testimony whereof I ax my signature doors curved around theiI` edges, as shown in presence of two Witnesses.

5 and set forth. JOHN VANES.

3. A boiler-front of wrought-iron or steel, Witnesses: provided with a vertical expansion-joint be- F. J. JAMES,

tween the furnace-doors and a vertical ex- JOHN DALTON.
