PETER F. MURPHY, OF MILWAUKEE, WISCONSIN.

BOILER-STAND.

To all whom it may concern:

Be it known that 1, PETER F. MURPHY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Boiler- Stands, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

The main objects of this invention are to provide a cheap, light and sanitary knockdown stand of simple and durable construction for household boilers, which can be easily set up and taken apart and p aeked and shipped in small compass, and which will squarely and firmly stand on a floor and support a boiler; to adapt such a stand without adjustment to boilers of different sizes; and generally to simplify and improve the construction and increase the convenience of devices of this class.

It consists in certain novel features of construction and in the peculiar arrangement and combination of parts hereinafter described and pointed out in the claims.

In the accompanying drawing like letters designate the same parts in the several figures.

Figure 1 is a plan view of the stand, one of the arms being broken away and shown in cross section; Fig. 2 is a side elevation and vertical section on the line 2 2, Fig. 1; and Fig. 8 is a cross section on the line 3 3, Fig. 2.

The stand is composed of similar, separable sections each comprising an arm a and leg I), and formed with a vertical bearing face or lateral bearing 0 and with vertically perforated angular lugs d. The arm a and legs I) diverge or are bent outwardly from the intermediate bearing faces 0, forming a tripod when the parts are assembled. The vertical faces 0 are adapted to bear against each other at their edges and thus firmly hold the radiating arms and legs of the stand equidistant from each other when the parts are assembled and secured together,- as shown in Fig. 3. The lugs on each section are spaced to fit between the lugs on the adjoining sections, as shown in Fig. 2, care being taken to make a good fit between the adjoining horizontal faces of the two upper and the two lower lugs, and the parts are fastened and firmly bound together when assembled by a single bolt or 4 in c passing vertically through the several ugs. The vertical bearing faces 0 prevent lateral displacement, and the lugs d prevent Specification of Letters Patent.

vertical displacement of the sections when they are bound together by the bolt 0, which is provided at its lower end with a nut 0. One of the sections is formed with a stop 0 as shown in Fig. 3, for holding the nut from turning while the bolt is being screwed into it. One of the sections is formed above its upper lug (1 with a shieldf, preferably of circular form, which extends over and covers the joints between the sections, as shown in Fig. 1.

At their upper ends each of the arms a is formed with a number of seats 9 and h to receive and hold the rims or flanges at the lower ends of boilers of different diameters, so that the stand is adapted without adjustment to boilers of the sizes most generally used. The seats g and 72 are separated from each other by upwardly projecting lugs t which securely hold a boiler of either size central with relation to the stand.

With three legs and arms, as shown, the stand will rest evenly and firmly 011 a floor which may be waned or uneven and the boiler will bear equa lly and rest firmly in the seats at the upper ends of the arms, the weight being equally distributed upon the three sections. The bases with which boiler stands are commonly provided and which require an even floor or foundation. to firmly support them and the ordinary flanged rings which carry the boilers and into which it is frequently difficult if not impossible to fit them, are thus dispensed with, thereby simplifying the construction of the stand, facilitating the setting of boilers, and avoiding the accumulation of dirt underneath the bases and the unsanitary conditions incident to the use of stands having solid extended bases.

By removing the bolt 6 the sections of the stand can be taken apart and bound or packed compactly together for storage and transportation.

To stiffen and strengthen it and at the same time to admit of reducing the weight of the casting, each section is formed with a flange 7' extending from its upper end down the inner edge or margin of the arm portion and forming the vertical bearing face 0 at the junction of the arm and leg portions, from which it extends downwardly across the leg portion and thence along its outer edge or margin to its lower end, where it terminates in a foot 76 having a smooth spherical lower face. Each section is also preferably formed with a narrow flange Z extending on its outer edge or margin from its upper end to the flange 1', and with a like or similar flange m, extending on its inner edge or margin from the lower end of the vertical bearing face 0 to the foot it. he flanges being wider than the flanges Z and m and located above them, serve to prevent to a great extent dust and dirt from falling and lodging on the narrower flanges where it would be less accessible and more difficult to remove. The spherical bearing faces of the feet 7r facilitate moving the stand with a boiler into place in setting the boiler and prevent scratching and marring the floor on which it is moved.

Constructed as snown and described, the sections require no machine work to finish and fit them together, and the greatest rigidity and strength are secured with the least weight.

The bolt holes in the lugs (Z may be formed with cores in casting or they may be made open on one side, as shown in Fig. 3, thus rendering cores unnecessary.

I claim:

1. A boiler stand composed of separable sections formed between their ends with interfitting lugs having registering vertical bolt holes and adjacent thereto with lateral bearings adapted by engagement with one another to positively hold the sections in predetermined angular relation to one another when they are assembled and secured together, and a bolt adapted to pass through the lugs of the several sections and to immovably secure said sections together, each section having a boiler seat at its upper end, substantially as described.

2. A boiler stand composed of separable sections formed between their ends with vertical bearing faces and vertically perforated interfitting lugs, the perforations in the lugs registering with one another when the sections are assembled, and a bolt adapted to pass vertically through the several lugs and secure the several sections together, one of the sections having a shield which projects over the joints between the several sections, substantially as described.

A boiler stand composed of separable sections formed between their ends with vertical bearing faces and vertically perforated lugs, the perforations in the lugs registering with one another when the sections are assembled a bolt adapted to pass through the several lugs to bind the sections together, a shield covering the joints between the sections and a stop to hold the nut while the bolt is being screwed into it, substantially as described 4. A boiler stand composed of separable sections, each comprising arm and leg portions and having a flange extending along the inner edge of the arm portion, forming a vertical bearing face at the junction of the arm and leg portions and extending thence across the leg portion and down its outer edge, substantially as described.
