Specification 0f Letters Patent.
Patented July 26', 1921.
Application filed September 10, 1919. Serial No. 322,875.
To @ZZ w from t may concern.'
Be it known that I, ETIIAN I. DoDDs, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, ,have invented certain n-ew and useful Improvements in Staybolt Structures; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in staybolt structures for boilers,one object of the invention being to provide a bearing sleeve or member which may have a universally movable mounting near one or the other vof its ends in the outer boiler sheet and which shall be so constructed that its intermediate portion may be mounted in a conical opening in the boiler sheet when the wall of said opening is straight transversely of the sheet.
With this and other objects in view, the invention consists in certain novel features of construction as hereinafter set forth and pointed out in the claim.
In the accompanying drawings; Figure 1 is a sectional view, partly in elevation showing one way in which the bearing sleeve or member may be mounted in the boiler sheet, and Figs. 2 and 3 are views showing other ways in which the bearing sleeve or member is capable of bein;r mounted.
1 representsan Outer boiler sheet and 2 the inner sheet of a boiler. ln Fig. 1 the outer boiler sheet is shown as provided with an opening 3, a portion 4 of the wall of which may be made tapering and straight throughout a portion of the thickness of the sheet, and another portion, 5, of `the wall of said opening is made rounded to form a Seat on which a bearing sleeve or member may have a universally movable or adjustable mounting.
The bearing sleeve or member is made interiorly with a rounded seat 7 for the rounded head 8 at the outer end of a staybolt 9 the inner end of the latter being secured to the inner boiler sheet 2 in any suitable manner. The body portion of the bearing sleeve or member is curved or rormded eXteriorly near its inner or lower end, as at 10, and at the upper or outer end, the bearing sleeve or member is made with a head or enlargement 11, the ou-ter face of which is curved or rounded transversely as at 112L to afford a universally movable mounting for the sleeve on the curved portion 5 of the wall of the opening in the boiler sheet when it is desired to mount the sleeve in the outer boiler sheet in such manner flush with the outer face of said boiler sheet as shown in Fig. 1. Nhen the bearing sleeve shall have been properly adjusted to insure accurate alinement of the staybolt with its points of connection with the respective boiler sheets, the rounded head of the sleeve will be united to the boiler sheet by means of a weld 12.
That portion of the body of the bearing sleeve or member which is intermediate of the head 11 and the rounded inner or lower end portion 10, is tapering and straight as shown at 10a and the opening in the boiler sheet l may be made tapering and straight, as at 10b to receive it, as shown in Fig. 2. lVhen the bearing sleeve or member is thus mounted, the weld 12 will unite the same with the boiler sheet nea-r the juncture of the straight tapering portion 10a and the head 1 1 of the sleeve.
en it is desired to mount the bearing sleeve in the boiler sheet so that it will project outwardly from the same and have a universally movable mounting at its inner ,or lower end in the boiler sheet, a portion of the wall of the opening 3 will be made to afford a rounded seat 17 for the rounded inner or lower end portion 10 of the sleeve, and when the latter shall have been properly adjusted, it will be united to the boiler sheet by a weld, indicated at 18.
The enlarged or headed outer end portion of the bearing sleeve or member 6 may be threaded interiorly to receive a hollow threaded plug or closure 13 having an angular portion 14 to receive a wrench. A gasket 15 may be located between the inner end of the plug and a shoulder 16 within the sleeve or bearing member 6.
its outer end and having its inner end portion rounded exterlorly, saidV bearing member my invention What to secure by Letalso having a straight tapering exterior por tion between its rounded inner end portion zuid its rounded head portion. Y
In testimony whereof` I have signed this specification in the presence of a Subscribing Witness.
