This invention relates to an adjustable stand for supporting uprightrange boilers or objects of that form, and it is the object of the invention primarily to provide'an inn proved stand of this character which is simple and sturdyof construction, which is adapted to be adjusted and applied to boilers .of dif ferent diameters with a minimum amount of laborpwhicliis capable of being folded into a compact package: for shipping and storage jpurposes when not in use withoutrequiring the dismembering of any of its parts, and

l which may be manufactured "ata low cost.

The novel features whichcharacterize the i5 invention andtheir advantages willbe better understood when the following detailed description is readin. conjunction with the accompanying drawings ofwhich Fig. l is a view illustrating a stand embodying the an invention as it may be used; Fig. 2 a per spective View of the stand to enlarged scale; Fig. 3 a view showing the stand folded for storage or shipment; and Fig. 4: a view of one of the combined leg and cross arm sections detached.

In accordance with the invention and as is illustrated in the drawings, a boiler stand is provided which comprises a plurality of similarly constructed combined leg and cross nected together by a single bolt. These sections, which in the preferred form of the.

face on the outside of the stand, is more rigid and also otherwise better adapted to such use. A small portion 3 of the radially disposed flange at the top of each leg member is cut awayto form a lug 4 which is employed to engage the edge of a boiler and hold it in place on the stand.

The cross arm member 2 is made from a relatively wide piece of strip metal, such as arm sections all of which are adjustably con- 7 While the leg members 1929. serial No. 370,026;

strip steel, and is rigidly connected in a vertical manner to the {radially disposed flange portionof the leg member. To give rigidity to the stand and to facilitate'the joining of the different sections together, the cross arm is twisted beyondthe pointwhere' itis connected to the legmember through an angle of 90, and in such a way thata liesin a liorizontalplane. An elongate slot 5 is formed in this horizontally disposed portion of the arm to provide for adjustably oining the various sections of the :standtogeth'e r. When the stand is assembledthe horizontally disposed portions ofthe differ, ent crossarms are laidone on top of the other with their elongate slots 5 inregister, and

in place, a nut 7 being turned onthe bolt to rigidly clamp the sections together. After the nut. screwed. on the bolt the threaded end of the bolt is alnmed sufficiently topre vent the nut coming off, but not sufliciently to interfere with the movement of thenut enough to prevent adjustlnentofthe stand.

In this way the nut is prevented from getting lost and the parts of the stand from coming apart.

As will be appreciated, the width of the cross armand twisted portion 8 thercoffunc- "substantial portion of the free end'of the arm a bolt 6 ispassed through them to hold them i tion to increase the rigidity of the stand, since both strengthen the cross "arm against deflection from both horizontal and vertical forces, which when encountered tend to .twist the stand out of shape. The rigidity of the stand is also further increased by the. mounting of the'cross arms in the midportion of the leg members, since, by connecting them to the leg members at that point, the stand is less liable tobe twisted out of shape it is slid along the floor when loaded orwhen a boiler mounted on itis rotated Without the stand itself being rotated. r

fTo obtain the greatest possible rigidity in the cross arm, the twisted portion 8 is started at the point where it joins the leg andextend ed inwardly along the leg as faras ispossible without its interfering with the adjustability of the "stand, the limit being determined by the flat portion required at thefree' ends of the arm to permit of the necessary radial movement of the s ctions for adjustment.

By providing elongate slots 5 in the cross arms and using only a single bolt 6 to hold all the sections together, it is possible to adjust the stand to the proper size to fit a boiler by merely loosening nut 7 and radially sliding the section together or apart as may be necessary and then retightening the nut. If one of the legs should be sli htly out of true after the boiler is placed on the stand, nut may be loosened and the leg tapped to place Without disturbing the other sections of the stand, and due to the rigid connection between the cross arms and the legs, it the stand is found to be too high for certain uses, the portion of the legs below the cross arms may be cutoil without weakening the stand.

As is illustrated in Fig. 3, when the stand is not in use, or when it is being shipped, it may be folded into a very compact form by merely loosening nut 7 and rotating the sections into a nested posltion. made possible by the twist and slots 5 1n the This feature is cross arms which permit the arms to be shitted with respect to each other and snugly h nested together.

As willbe readily appreciated by plumbers, and others skilled 1n the art, there is a real advantage in being able to lit a stand of this 7 character to a boiler or told it for shipment by merely adjusting a single bolt, and especially so when such a small amount of time and labor are required to do it. In addition to this it is unnecessary to dismember any of the parts of the stand for shipping purposes or any other reason, Hence, the possibility of losing any of its parts either when it is being fitted to a boiler or when it is in storage or shipn'ient is greatly reduced. Another feature is that due to the limited space taken up by the cross arms the legs of the stand maybe made comparatively short and still allow sutlicient room below the boiler for attaching lit-tings thereto. Furthermore, each of the sections of the stand are identically alike and interchangeable, and because of their simple construction are capable of being fabricated or manufactured at a very low cost.

According to the provisions of the patent statutes, 1 have explained the principle and operation of my invention, and have illustrated and described what I now consider to represent its best embodiment. However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.

I claim:

1. Aboiler stand comprising a plurality of combined cross arm and leg sections each of which consists of an uprightly disposed leg member anda radially disposed cross arm, said leg members consisting of a straight angle member notched on its upper end to e11- gage the lower edge of a boiler, said cross arm being formed from a flat piece of strip metal rigidly attached in a vertical plane to said leg member and extending at right angles thereto, said arm being twisted through an angle producing a bend portion therein adjacent said leg member and placing its free end in a horizontal plane, said horizontally disposed portion being provided with an elongate radially disposed adjustment slot, and a bolt extending through said slots and adj ustably holding the sections of the stand together.

A boiler stand comprising a plurality of combined cross arm and leg sections each of which consists of a vertical leg member and a radially disposed cross arm member having a bolt-receiving opening in its free end, said cross arm member being formed of a flat sturdy piece oi strip metal rigidly secured in vertical plane at right angles to the leg member and twisted'laterally throughan angle placing a portion of its free end in a horizontal plane to adapt it for attachment -to the same portion of the cross arms of the other-sections ot' the stand, and a bolt passing through the boltreceiving holes of the d ilierent cross arms to hold the sections of the stand together.

in testimony where-of, I sign my name.
