Be it known that l, ETHAN I.

, as indicated' in Figure 1,5and Yin tliez'embodi-V ment of the"inventiontshown in F iguresfhf' 2 and 3, the said ring is oircularn cross?v`r` section. The bearinglsleeve 5 is provided interiorly Witha `curvedseat 7 forthehead 105 3 of the 'staybolt;, The bearingsleeve fis also' threaded'internally for the accommo-'jg f dation of an externally threaded cap or therein.
have been so positioned that its opening will be in alignment with the hole in the inner boiler' sheet Vthrough which the inner end oit the stayboltis screwed, the said ring or supporting memberwill be permanently secured to the outer boiler sheet by means ot a weld indicated at 11 and the sleeve or bearing member willbe permanently secured vto the ring or supporting member' by means ofY a Aweld indicated at 12. The staybolt 3- may now, be passed through the bearing member to the inner boiler sheet and secured to the latter and the cap 8 may then be screwed into the sleeve or bearing member over the head of the bolt. v Y Y Instead of making the ring or support cir- Ycular in cross-section, I may provide a ring or support y13 having iiat upper and lower faces so that said ring will be angular in cross-section, as indicated in Figure 4.
Instead of making the sleeve or bearing member 5 with a seat which is curved transversely, as shown in Figure 1, for the accommodation of the ring or support 4, I may provide the sleeve or bearing member with a beveled tace 14 (straight transversely) as shown in kFigure 5.
Thel sleeve member 5' may, if desired, be
Anot provided with either a transversely curved or straight beveled tace, but the bottom of said sleeve member may be mounted directly-uponthe ring or support as indicated in Figure '6 and the bolt head mounted on a seat 1a in the boiler sheet at the opening InlFigure 7.71 have shown the bottom portion of the sleeve or bearing member provided with a Vbeveled face- 14 extending transversely upwardly and outwardly, and the sleeve or bearing member resting upon kthe ring or support 4 at the inner edge of such beveled portion,-a. weld 15 being disposed V between said beveled portion of the sleevefand the supporting ring and a similar weld 16 being disposed between the support- Y ying ring and the boiler sheet;
InV Figure 8, IV have shown a sleeve or housing 17 welded to the outer boiler sheet and provided with a removable cap or closure 18 and in this construction the wedge ring 4 is disposed between the rounded head 19 of a staybolt 2() and the outer face of the boiler sheet. In this construction the ring 4 need not be welded to the boiler sheet but it may be readily adjusted to insure proper alignment of the bolt with the hole in the inner boilerrsheet which receives it.
In Figures 9, 10 and 11, a supporting ring is shown as having beveled outer and inner faces 24-25 and the bottom of the bearing sleeve or member 26 is formed With a transversely curved face 27 to rest on said ring. l' r Having jrully described my 'invention what I claim as new and desire to secure by Letters Patent, is:
l. A supporting and adjusting member :for use in a staybolt structure, said member. having wedge shape and providing opposed seats to engage, interchangeably, a housing lmember orstaybolt head and a boiler sheet.
2. rifhe combination with a boiler sheethaving a bolt opening and a staybolt having a head Jfor connection with the boiler sheet, of an initially adjustable housing member for the bolt head, a wedge-shaped member interposed between said housing member and the boiler sheet, and means securing said wedge-shaped member to the housing and to the boiler sheet.
8. In a staybolt structure, the combination with a boiler sheet having an opening, of a bearing member, a staybolt having its head mounted in saidV bearing member, Vand a wedge-shape supporting and adjusting member made annular in form and disposed be,- tween said bearing member and the boiler sheet and welded toA both.
4. In a staybolt structure, the'J combination with a boiler sheethaving -a bolt opening, of a bearing member having an external seat at its inner end, an annular wedgeshape supporting and adjusting member disposed between said seat and the outer face of the boiler sheet, means securing said mem'- n Vber to the boiler sheet, means securing saidA Vmember and the bearing member together,
and a staybolt havingva head mounted in said bearing member.
5. In a staybolt structure, thel combina-l tion with a boiler sheet, a bearing member :tor the head of a staybolt, and a staybolt having a head mounted in said bearing member, of a curved Vwedge member initially adjustable between the bearing member and boiler sheet, and means securing said curved wedge member in place.
6. Supporting and adjusting means for the bearing member of a staybolt structure, consisting of a curved wedge-shape *mem* ber, said member also having wedge shape in cross sectionV from its inner edge outwardly.
