drawings, which form a part of our specification.
Our invention relates to foundation rings more especially intended for use in connection with the locomotive or open type of steam boiler provided with upwardly presented water-tubes.
The object of our invention is to provide a foundation ring for the fire-box of a boiler of the type specified, adapted to provide water-circulating chambers in the foundation ring arranged to have communication with the water-tubes of the tire-box and with the water-legs provided intermediate of the flue-sheet and throat-sheet and intermediate of the door-sheet and back-head of the fire box. 7
A further object of our invention is to provide a foundation ring wherein the portions or sections, provided with the water chambers, may be made of comparatively light material, such as steel plate, rolled or otherwise shaped into proper form, so as to provide a foundation ring of the character specified which will be comparatively inexpensive to manufacture. The construction, at the same time, is such as to provide a rigid and watertight connection, with the transversely extending portions or sections of the foundation ring preferably made solid. thus permitting these portions to be made of cast steel. The solid or transversely extending portions of the foundation ring are also preferably provided with ports at points where they are connected with the chambered or hollow portions of the foundation ring so as to enable circulation between the chambered portions of the foundation ring and the front and back waterlegs; the bottoms of the water-legs being closed by the-solid transversely extending portions of the foundation ring.
As is apparent from the foregoing description, the invention provides a foundation ring made in sections, with the hollow longitudinally extending portions rigidly secured to the solid transversely extending portions in any suitable manner, as, for example by employing either the autogenous or electric methods of welding the'respective portions together so as to form a rigid and water-tight construction, as will be more fully understood from the following detailed description of the drawings wherein Figure 1 is a perspective view of our improved foundation ring, partially shown in section and with one end of one of the longitudinally disposed portions shown unattached tonne of the transversely extending portions; this last portion being made in accordance with the form shown in Fig. 2.
Fig. 2 is a cross-section, taken through one of the longitudinal portions or sections, on the line AA of Fig. 1. Fig. 3 is a similar sectional view taken on the line B-B of Fig. 1, illustrating the longitudinal section made substantially similar to the opposite section, except being provided with a. staysheet member. Fig. i is a perspective view of a modified form of our invention, not only illustrating thev foundation ring provided with a central longitudinal section or portion, but with the longitudinal sections or portions formed in a different manner from that previously illustrated; a portion of one of the longitudinal sections or portions be ing broken away and with one end of said section or portion shown unattached to the.
transverse section or portion. Fig. 5 is a sectional view taken on the line CC of Fig. 4, illustrating'the, construction of the longitudinal sections or portions of the foundation ring shown in Fig. 4, except that the section is shown provided with a reinforcing member or stay bolt. Fig. 6 is a vertical sectional view through a water-tube lire-box provided with our improved foundation ring, as illustrated in Fig. 4.
In the particular exemplification of our invention as illustrated in Figs. 1 and 2' the ends or transversely disposed portions or sections 10 and 10 of the foundation ring are made of any suitable metal, preferably cast steel and solid throughout, except for the ends hereinafter to be described. The sections or ends 10 are provided with the depending portion 11 which constitutes an anchor for the expansion pad usually arranged between the back-head and the engine-frame, while the section or portion 10 is provided with the depending portion 12 adapted to constitute a suitable anchor or stay between the throat-sheet and the engine-frame. The ends or transversely extending sections 10 and 10 are so con structed as to permit the throat-sheet and flue-sheet and the door-sheet and back-head these ends of the transversely extending sec-' tions are preferably cored so as to provide ports 13, 13, 13, 13 adapted to communicate with the longitudinally disposed portions of the foundation ring, while the outer ends of the ports 13 are disposed upwardly s as to communicate with the front and rear waterlegs of the fire-box. 4
In order to efiect proper connection between the flue-sheet and door-sheet and the transversely disposed portions of the foundation ring at points coincident with the ports 13 we prefer to provide the solid or transverse sections or portions of the foundation ring with the upwardly. presented flanges or portions 14 which are preferably provided with holes t permit the door-sheet and flue-sheet to be riveted thereto as is usual in locomotive practice.
The side or longitudinally disposed portions or sections of the foundation ring, as illustrated in the first three figures of the drawings, are composed of sheet steel, preferably rolled, so as to provide the substantially angular members or portions 15 and 16, see Fig. 2. The portion or member 15 is adapted to constitute the top and one side wall of the longitudinal section of the foun dation ring while the member or portion 16 is adapted to constitute the other side wall and bottom of the longitudinal section of the foundation ring; the member or portion 16 forming what may be termed the outer side of the foundation ring, as illustrated in Fig. 1. The portion of member 15, which constitutes the top of the longitudinal section of the foundation ring, is flanged, as indicated at 17 so as t extend parallel with the portion of member 16 which constitutes one of the side walls of the longitudinal section, while the portion of member 16, which constitutes the bottom of the longitudinal section of the foundation ring, is flanged, as
shown at 18, so as to extend parallel with sections of the foundation ring may be secured together by suitable studs or bolts 19, 19, which will enable one of the walls, namely wall or member 16, to be readily removed for the purpose of giving access to the interior or chambers of the longitudinal sections and, therefore, also to the ends of the water-tubes which are received in the openings 20, arranged in the part of portions 15 which constitute the top of the longitudinal section of the foundation ring. In order to provide a fluid-tight connection or joint, we have illustrated each of the longitudinal sections of the foundation ring provided with a suitable gasket 21, interposed between members 15 and 16 both at their upper and lower contacting points, as more clearly shown in Figs. 2 and 3.
In the construction illustrated in the first three figures of the drawings, the wall or member 15 is rigidly secured to the transverse or end- sections 10 and 10 of the foundation ring, as, for example, by welding the member or wall 15 of the longitudinal sections to the transverse or end-sections so as to provide an integral construction in which merely one side wall and the bottom of the longitudinal sections of the foundation ring may be removed. In order to provide as large a welding surface as possible and insure a firm connection, we prefer to bevel the angularly disposed ends of the transverse or end sections 10 and 10 as shown at 22 in Fig. 1, so as to receive the protruding or extended portion 23 of the wall or member 15 of the longitudinal sections, thereby providing a diagonally arranged joint which will present a longer surface to be welded, and prevent the possibility of a transverse fracture; the completed or fused connection being indicated at 24 in Fig. 1. I
The member or wall 16 is made to slightly overlap the juncture between the ends of the transverse sections 10, l0 and the members or walls 15 of the longitudinal sections, as can be seen in Fig. 1, at which point the ends of the members or walls 16 may be provided with. additional securing means such as studs or bolts 19; the gasket 21 being arranged, as will be understood, to extend in an angular manner in order to effect a proper water-tight joint at this point.
In Fig. 4:, we show a modified form of our invention, wherein the foundation ring is provided with an intermediate longitudinal section so as to adapt it to a fire-box pro-- vided with water-tubes disposed along the longitudinal center line of the fire-box. The construction shown in this figure differs also from that previously described, in that the longitudinal sections are made of suitable metal, such as sheet steel, rolled into channel form, as more clearly shown in Fig. 5, so that the top and two side walls are formed integral, as shown at 25. In this construction, the top and both side walls are intended to be fused or welded to the trans verse or end sections 10 and 10 The transverse or end sections 10 and 10*. are made substantially similar to those shown in Fig/ 1 and previously described, except that. each end or transverse section is provided with an additional or intermediate port 26, adapted to register with the chamber provided by the hollow intermediate longitudinalsection of the fundation ring.
When this construction is employed, the transverse or end sections are'also provided with the upwardly presented flange 27, in order to permit the fine-sheet and door-sheet to be properly secured to the foundation ring at this intermediate point; because where an intermediate or central longitudinal section is employed, it becomes necessary to cut out the door-sheet and flue-sheet in order to enable it to straddle the, intermediate longitudinal section of the foundation ring.
The top portions of the longitudinal sections are also preferably provided at their ends with an upwardly presented flange 28, see Fig. 4:,which is adapted to abut against the flanges 14 of the transverse or end sections, and provides additional surface for welding; the ends of the longitudinal sections, like those illustrated in Fig. 1, as well as the abutting ends of the transverse sections, being preferably beveled so as to pro vide a larger surface for welding so as to prevent the possibility of a transverse fracture. The welded or fused ends of the longitudinal and transverse sections will pro vide a water-tight joint, as clearly shown at 2% at the right hand end of Fig. 4-.
The lower ends of the channels 25, constituting the longitudinal sections, are preferably enlarged transversely so as to provide suitable bolt-receiving portions 29, more clearly shown in Fig. 5. The enlarged portions 29 receive the studs or bolts 30, whereby the bottom plate or member 31 is removably secured in place. In order to effect a fluid-tight joint between the bottom or cover plate 31, and the sides of the channels constituting the longitudinal sections, we prefer to provide a gasket of any suit able material, as shown at 32, see Fig. 5.
Where the longitudinal sections are madeof comparatively deep channels, they may be provided with a series of stay-bolts or members 33. see Fig. 5, whereby the longi tudinal sections will be prevented from spreadingg-a suitable number or series of tudinal sections of the foundation ring and the upper part of the fire-box or boiler; the ends of the water-tubes being secured in any suitable manner, common to boiler practice, but preferably by welding them integrally in the openings, which is made possible by reason of the removable bottom or cover 31, which gives complete access to the interior of the channel.
In F ig. 3, we illustrate, in cross-section, a slight modification of the longitudinal section shown in Fig. 2 and employed at the far side in Fig. 1. The top and one side wall of the longitudinal section, like that in Fig. 2, is formed by the angle iron 15, constructed as shown in Fig. 2, while the opposite side wall and bottom 16 is similar to that in Fig. 2, except the bottom flange is of less width, as shown at. 16 Both wall members 15 and 16, like those in Fig. 2, are provided with the flange portions 17 and 18,- respectively, in order to permit the two members or walls to be properly secured together, as by means of the studs or bolts 19-. The construction differs from that disclosed in the far side of Fig. 1 and in Fig. 2, in that we provide the bottom of the section with an intermediate or reinforcing member 35, preferably of considerable thickness. The member 35 is formed integrally with the transverse sections 10 and 10 as disclosed in the near side of Fig. 1. The
lower endsof the wall members 15 and 16 of the longitudinal sections are clamped or secured to the reinforcing member 35 by bolts 19. as shown, in Fig. 3. The reinforcing member 35 will greatly strengthen and stiifen. the'longitudinal sections or portions of the foundation ring, so'that it will be capable of withstanding great pressure or therefore, to the ends of the water-tubes,-
may be had by simply removing the bolts 19, so as to permit the angle member 16, constituting one side and the bottom of the longitudinal sections, to be readily removed;
or where the construction illustrated in Figs 4- and 5 is employed. by simply removing the bolts 30 to permit the bottom 31 to be removed.
in constructing the foundation ring in the manner herein described, it is evident that the portions which are made hollow, so as to provide the water-circulating chambers, may be made of rolled steel or, in other words, of metal having the desired density and grain adapted to withstand the pressure 'to which the sections are subjected, thus overcoming the objections that would be encountered 'in foundation rings in which the chamber or hollow sections were cast. The use of cast metal, owing to its porosity, is not adapted to withstand and hold the fluid under pressure, unless the cast walls are made exceedingly thick and heavy which would make the foundation ring undesirable on account of its weight, and, therefore, impracticable for proper manipulation and application.
We have shown and described what we believe to be the simplest and best forms of our invention, but the same may be altered in certain respects without, however, departing from the spirit of our invention, and we do not wish to be understood, therefore, as
limiting ourselves to the exact constructions shown and described.
