BOILER STAND Filed Nov. 23, 1929 J INVENTOR Patented Oct. 24, 1933' UNITED STATES BOILER STAND Lawrence W. Luff, Shaker Heights, Ohio, assignor v to The Consolidated Iron-:Steel Manufacturing Company, Cleveland, Ohio, acorporation of Ohio Application November 23, 19 29 Serial No. 409,303
4 Claims. (o1. 248-41) This invention relates to boiler stands of the type employed for supporting a domestic hot water boiler.
The objects of thev present invention are to 5 provide a novel form of such stand which shall be of extreme simplicity and of corresponding economical manufacture, and more particularly to provide such a stand of a'minimum number of principal parts each of which maybe readily cast of metal.
vide a novel arrangement of parts which may be assembled in compact form for shipment and may thereafter be arranged to form the boiler stand without disassembly.
The exact nature of my invention together with further objects and advantages thereof will be apparent from the following description taken in connection with the accompanying drawing in which Fig. 1 is a view in elevation of a stand embodying my invention indicatingin dot-dash lines a boiler supported thereon; Fig. 2 is a similar view showing the stand inverted to support a different size of boiler, indicated in dot-dash lines; Fig. 3 is an enlarged detail showing the interconnecting portions of the principal parts assembled, as looking downwards upon the central portion of the parts as shown in Fig. 1, or v upwards toward the same as shown in Fig. 2; Fig. 4 is a View showing the principal parts-separated and arranged in corresponding relation; Fig. 5 is a plan view of the right-hand part appearing in Fig. 4; and Fig. 6 is a plan view of the boiler stand assembly arranged in shipping relation.
With reference now to the drawing my boiler stand comprises three principal parts A, B, and C, the assembly of which may be completed by means of a single additional part D as will appear.
Each of the three principal parts comprises a vertical leg member 1, and an integral arm member 2 laterally extending therefrom in a medial vplane.
Each of the arms 2 is preferably thin and fiat and lies in a horizontal plane, when the assembly is completed.
Each leg 1 is also preferably thin and flat and 5 lies generally in a plane which is radial of the boiler stand when the assembly thereof is completed. Each leg 1, on either side of the plane ofits arm 2, is perpendicular thereto and has N no section greater than that at said plane. Thus each part lends itself nicely to casting from A further object of the invention is to pro metal, in a mold which is parted in the plane ofits arm 2. I I
The planes of the arm members 2, when the leg portions 1 are aligned as in Fig. 4, are not coincident. Instead the free endportions of the arm members 2 of two of the parts are sufliciently spaced to clear the arm of the thirdpart therebetweenwhenthe legs 1 are aligned as in Fig. l, the arms 2 however having their end por tions parallel when the parts are so arranged.
Each arm 2 hasat itsend portion an extension 3 at 120 from the remaining arm portion in the plane thereof. .At the bend at the base of theextension of each arm member is provided a through opening 4. I I
It will be apparent from what has thus far been described, that by extending thev securing part D, indicated as abolt, through the openings lot the three principal parta'the' parts maybe secured together, arranged, for shipment in com pact relation asindicated Fig. 6, withtheir arms extending in the same general direction and their leg members adjacent each other and the pri ncipal parts may be swung about the securing part D to assume their proper relationto, form the boiler stand asindicatedFig. 1. There being three principal parts their relation in the boiler stand is with their arms spaced 120 apart, Since each arm extension 3 is 120 from its main arm portion, when the three arms 2 are at 120, the parts will then have the overlapping relationship indicated Fig. 3.
As indicated in Fig. 6, as looking downwardly upon the parts as shown Figs. 1, 8 and 4, the extensions 3a and 3b are each to the right of its arm whereas the extension 30 is to the left of its arm.
Inside the bend of each arm I provide an opening 5 which may conveniently be a through opening. The openings 5 are central of their arm sections and equidistant from the corresponding openings 4. Therefore when the parts are assembledas in Fig. 6 the openings 5 are aproximately aligned and sufliciently so that a cotter or like pin may be inserted therethrough to maintain the shipping relation of the parts until the erecting job is reached.
Each of the extensions 3 is provided with a projection 6, all of these projections being equidistant with the openings 5 from the central opening 4. As indicated particularly in Fig. l the projection 62) on the B part extends downwardly, the projection 60 on the C part extends upwardly, and the projection 6a on the A part extends downwardly although the projection 6a might extend upwardly or in both directions. Obviously when the parts are arranged as in Figs. 1, 2 and 3 each projection 6 will register with one of the openings 5 and will be engaged thereby to maintain the angular relation of the principal parts at 120.
As indicated Figs. 1, 2 and 4 each extremity of each leg 1 is provided with a notch '7 adapted to receive the lower edge flange of a boiler 8 of standard size for supporting the boiler in elevated position above the floor 9.
Each leg portion 1 on one side of the plane of its arm member is preferably offset relative to that portion on the other side as indicated Figs. 1, 2 and 4. Thus the boiler stand may be inverted as indicated Fig. 2 and will then be adapted to support a boiler 10 of a different standard size from that of the boiler 8.
What I claim is: r
1. A boiler stand comprising a plurality of similar parts each part comprising a vertical leg member and an arm member extendinglaterally therefrom in substantially horizontal direction intermediate the ends of the leg member, a portion of the arm member, spaced from the leg member, being arranged in a substantially horizontal plane, said arm member having at its free end a bend in the plane thereof and an opening, and having bothmale and female projection and recess means adapted to interlock with a corresponding recess and projection means of another similar part, whereby the said arm members may be disposed with the openings thereof aligned and with the arm members disposed at predetermined angular relation with each other and whereby the arm members may be secured to each other by clamping means extendng through said aligned openings, and maintained in said angular relation against rotation in either direction around said openings by the interlocking,
of said projections and recesses.
2. A part for a boiler stand of the class described and comprising a vertical leg member and an arm member extending therefrom in a horizontal plane medial thereof and arranged generally in said plane, said arm member having at its free extremity a bend in said plane, witha through opening at said bend, and on either side of said opening a male and a female means adapted to interlock with the corresponding portion of another similar part, whereby said part may be secured with said similar part by means extending through said opening, and will be maintained in predetermined angular relation therewith by said interlocking means and against rotation in either direction around said opening.
3. A part for a boiler stand of the class described and comprising a vertical leg member and an arm member extending therefrom in a horizontal plane medial thereof and arranged generally in said plane, said arm member having at its free end an extension at 120 thereto in said plane, and being provided with a through opening, whereby said part may be associated with another similar part with its extension overlying the arm of the other part and its arm underlying the extension of still another part, the'arms of the parts being spaced at 120, and means asso-' an arm member extending therefrom in a horizontal plane medial thereof and arranged genorally in said plane, said arm member having at its free extremity a bend in said plane with an opening therethrough at the bendand having on one side of said bend 'a projection and on the other side thereof an opening adaptedto receive a similar projection, whereby said part may be secured with other similar parts to form a boiler stand, by means extending through said through opening, and will be maintained in predetermined angular relation withsaid other parts against rotation in either direction by engagement of its projection with the corresponding openingof another part, and engagement of its opening with the corresponding projection of still another part.
