This invention relates to boiler stands of the type employed for supporting a domestic hot water boiler.

The objects of thepresent invention are to provide a novel form of such stand which may be assembled from a minimum number of principal parts most of which may be support part A is such th-at a number of these identically similar. A further object of the invention is to provide such a design of the principal parts that they may be readily and cheaply produced of cast metal.

The exact nature of the invention together with further objects and advantages thereof will be apparent from the following descrip tion taken in connection with the accompanying drawing in which Figs. 1 and 2 are elevation and plan views respectively of one of the principal parts of which a number are employed; Fig. 3 is a View in elevation of the complete assembled boiler stand; Fig. 4 is a bottom view of the assembly appearing in Fig. 3; Fig. 5 is a view corresponding to Fig. 4 but showing the parts so adjusted that the boiler stand will accommodate a smaller size of boiler; Fig. 6 is a vertical detail section as in the plane of lines 6--6, Fig. 5; and Fig. 7

is a vertical detail section as in the plane of i lines 7-7, Fig. 4.

With reference now to the drawing the principal parts of which the boiler stand is assembled are a number of similar support parts A which may be identical in form, and a bracket or spider part B with which all of the support parts are connected as will appear.

Each support part A comprises a straight leg member 1 having a notch 2 at one end, and an arm member 3 preferably integral with and perpendicular to the leg member centrally thereof. The two principal members 1 and 3 of each support part are preferably thin and flat so that as indicated, Figs. 1 and 2, when the leg member is disposed generally in a vertical plane its arm member 3 will lie generally in a horizontal plane. At

the freeend of the'arm member 3 one face, l

as the upper one, is provided-. with deformations 4 runningV transversely toy produce. the effect of corrugations. The;l arm. member 3` also has a through opening 5 vnear its free end and in the zone of thecorrugations 4. v

It will be observedzthat the formof the parts may be Vreadily produced in very closely adjacent relation lin almold 'parted in the y plane. of the armB.

rlheY bracket ypart B is provided with a number. ofradially disposed wayszr preferably in the'form'of grooves 'asindicated Fi-g. 7.` rlhese waysare each adapted to receive the free end portion ofthe armI Bovofuone of the support parts A, to allowadjustment of the arm along the way` but to maintain the angularity of the karm with the bracket part and thus with other arms in the other ways of the bracket; As indicated Iprefer to employ three support parts A. Hence the bracket B is provided with three ways 6 disposedv at 120o in a plane. In order to save weighty and material the bracket part.- B is made in the spider form shown with three arms 7 corresponding with the three ways 6, each arm being of channel section as shown Fig.,7.

The bottoms of the ways 6 are provided with transverse deformations 8 corresponding with the deformations 4 as indicated Fig. 6. A number of throughopenings 9, 10` and 11 in the bracket B are spaced along the ways 6 thereof, and the arrangement is such that any of the openings 9, 10 and 11 may register with the opening 5 of a support part the arm 3 of which is positioned in the corresponding way 6 of the bracket part B.

Therefore a boiler stand assembly may be completed fromr three support parts and one bracket part, by means of three bolts 12;

the bolts 12 extending through the openings dicated Figs. 3, 5 and 6, the innermost open- 'n Y' Y 1,878,787

ings 11 of the bracket part B are employed, so that the support parts are adjusted to innermost relative position. Obviously in this position the notches 2 of the legs l define a 5 circle upon which they are disposed at 120; so that the stand is adapted to support a boiler, receiving the lower circular edge of the boiler in the notches 2. Fig. 4E' shows the outermost set of openings 9 employed 10 to adjust the support parts A to outermost position in which the notches 2 are adapted to receive a boiler of correspondingly greater diameter. Obviously, the intermediate set of openings` l0 might be similarly employedv tov accommodate ,the stand'to an internriediate size of boiler. WhatIclaim is: Y x Y In a boiler stand of the class described;V a plurality of similarsupportfparts, each i having a vertical leg member and an arm member integral therewith located in a hori- Zonta-l plane, and a central bracket part, said bracket part having a plurality of radially varranged ways each adapted to receive an overlapping end portion of one of said arm members to position the corresponding support part in angularity with the other support parts about the bracket part, the ways of the bracket part having transverse horizontal serrations thereon, the arm members having transverse horizontal serrations meshed with those of the bracketv part, and vertical clamp bolts inaligned perforations of the ways and arm members whereby the bolts may prevent relative rotation of the arm'members and bracket part -in vertical planes and the serrations may prevent relativerotationin horizontal planes and whereby the bracket part and arm members may 40 be rigidly associated in predetermined Vangular and also predetermined radially spaced relation. p

In testimony whereof I hereby affix my signature.
