UNITED STATES PATENT o r c a. 1
THOMAS H. DRYNAN, on sEwIoKnnY, PE NSYLVANIA.
Application filed December 26, 1922 Serial No. 608,812.
To all whom it may concern:
Be it known that I,TI-IOMAS H. DRYNAN,
acitizen of the UnitedStates, residing. at
- The present invention relates broadly to supports, and more particularly to supports especially constructed to serve as boiler stands for domestic hot water boilers.
Heretofore it has been customary to pro vide diiferent forms of stands for maintaining hot water boilers in: predetermined positions with respect to the floor level. Usually, however, the stands have not been adjustable to permit effective use thereof with boilers of different diameters and they have not been capable of easy installation.
The present invention provides an improved boiler stand adjustable to receive and support boilers of different sizes and of such construction that the boiler may be easily mounted thereon.
In the accompanying drawings there are shown for purposes of illustration only certain embodiments of this invention, it being understood that the drawings do not define the limits of the invention as changes may be made in the construction disclosed without departing from the spirit and scope of my broader claims.
In the drawings:
Figure 1 is a top plan view of one form of stand embodying the present invention;
Figure 2 is a side elevation of the construction shown in Figure 1;
Figure 3 is a detail sectional view on an enlarged scale on the line IIIIII of Fig ure 1;
Figure 4c is a view corresponding to Figure 1, but illustrating a modified form of the invention; and
Figure 5 is a perspective view of one of the supporting legs.
It is desirable in a boiler stand of the character to which the present invention relates to insure the provision of adequate supporting means for carrying the weight of the boiler and its contained water. This support must be provided, irrespective of the different adjusted positions of the stand. In accordance with this invention, this result is accomplished by providing in the form of the invention illustrated in Figures 1, 2 and 3, a spacing member 2, preferably in the. form of a ring. This spacing member has an outside diameter which is preferably slightly less than the diameter of the smallest boiler'whichit is desired tosupport.
The spacing member has formed therein a series of adjusting slots 3, extending spirally or angularly from the central portion of the member outwardly. "These slots are adapted to receive bolts 4,- which extend therethrough for engaging the supporting legs 5. Each of these legs comprisesa Vertically'extending portion 6, adapted to directly car'rytheweight of the boiler, and a horizontally extending portion 7 formed with a series of openings In assembling the stand, the legs are placed in the approximate adjusted position in the slots 3, by properly positioning the bolts 42 therein. The parts'are then accurately positioned, and the nuts 9 tightened against the lower sides of the horizontally extending portion 7, to thereby hold the parts against movement. The boiler B is then mounted on the stand and the installation proceeded with in the usual manner.
If desired, each of the legs 5 may be formed with an upstanding lug 10, adapted to co-operate with the outside of the base flange of the boiler and prevent any lateral movement thereof. As the boiler assumes a position substantially as indicated in dotted lines in Figure 1, it will be apparent that its weight is directly carried 'bythe supporting legs. In Figure 3 the base flange of the boiler is shown as being directly above substantially the central portion of the legs.
In Figure 4, there is illustrated aslightly modified form of spacing member, particularly adapted for use with boilers of the larger sizes. I11 this construction, the slots 3 are preferably arranged in pairs and are of such number that four or more legs may be held in spaced relationship thereto.
The advantages of the present invention arise from the provision of an adjustable stand which'is easily installed and which is of such construction that the spacing member is not subject to any of the weight of the boiler.
1. In a boiler stand, a horizontally extending spacing member having a plurality of slots formed therein, all of said slots having one end thereof closer to the center of the spacing member than the other end, supporting legs provided with hprizontally' exspacing member having a plurality of spirally extending slots, having portions thereof in overlapping relationship whereby each leg cooperates with a plurality of slots, substantially as described.
3. In a boiler stand, a circular spacing member having a plurality of spirally extending slots, a plurality of relatively and individually movable supporting legs independently cooperating therewith, each leg cooperating with at least two of said slots and clamping means interconnecting said member and said legs and extending through said slot-s whereby adjustment of the stand is procured by releasing said clamping means and individually moving each of said legs circumferentially of the spacing member to eflect a radial movement of said legs, substantially as described.
4. In a boiler stand, a spacing member having a plurality of spirally extending slots arranged in pairs, a plurality of sup-- porting legs cooperating with said spacing member, each of said legs cooperating with a pair of saidslots, and clamping means interconnecting said member and said legs 'whereby adjustment of the stand is procured by releasing said clamping means and mov ing said legs circumferentially of the spacing member, substantially as described.
In testimony whereof I have hereunto set my hand.
THOMAS H. DRYNAN.
