HENRY LOWELL MOGULLOUGH, OF CROPSEY, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 789,622, dated May 9, 1905.
Application filed July 27,1904. Serial No. 218,487.
To (tZl whom it may concern:
Be it known that I, HENRY LOWELL Mo- CULLOUGH, a citizen of the United States, and a resident of Cropsey, in the county of Mc- Lean and State of Illinois, have invented a new and Improved Means for Attaching Boiler- Tubes to theTube-Sheets, of which the following is a full, clear, and exact description.
The invention relates to steam-boilers; and its object is to provide a new and improved means for attaching the boiler-tubes to the heads of the tube-sheets and arranged to pre vent leakage due to unequal contraction and expansion of the tubes and the tube-sheets.
The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation, partly in section, of a blank boiler-tube. Fig. 2 is a like view of the boiler-tube. Fig. 3 is a similar view of the same in position in the tube-sheet and prior to expanding the tube, and Fig. 4: is a like view of the completed structure or after expanding the tube and forming an internal and external bead thereon.
In carrying out the invention the boilertube A has its end portion A thickened in an inward direction and for a length somewhat in excess of the thickness of the tube-sheet B, which latter has an opening B, into which fits the end portion A, as plainly indicated in Fig.
The end portion A is formed on its peripheral face with one or more annular grooves A, spaced apart to leave one or more annular ridges A and a shoulder A".
The wall of the opening B in the tube-sheet B is provided with annular grooves B, corresponding in shape and position to the ridges A so that when the end portion A is in position in the opening B and the end portion is expanded in the usual manner by suitable tools then the ridges A enter and it the grooves B and the shoulder A becomes an annular bead butting against the inner face of the tube-sheet B.
The projecting terminal of the end portion A is formed into an annular head A, (see Fig. 4,) butting against the outer face of the tubesheet B, so that the latter is engaged at both the inner and outer faces by beads A A.
The ridges A are preferably rectangular in cross-section, as plainly illustrated in the drawings, so that when an unequal expansion and contraction of the boiler-tube and the tube-sheet takes place in either a longitudinal or a diametrical direction then the said ridges still remain in contact with the walls of their grooves in the tube-sheet B to prevent leakage.
In Fig. 4 the structure is shown in its completed form or after the specially-constructed end portion of the tube has been expanded within the opening therefor in the tube-sheet.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A boiler-tube having its end portion of reduced internal diameter, and provided externally of said end portion with spaced annular grooves and an annular ridge between the grooves, the outer faces of the ridge and tube being substantially in the same plane.
2. -A boiler-tube having its wall uniformly thickened at the end portion to reduce the interior diameter of the end portion, the latter having external spaced annular grooves, leaving an annular ridge between the grooves.
3. A boiler-tube having its wall uniformly thickened at the end portion to reduce the interior diameter of the end portion, the latter having external spaced annular grooves, leaving a plurality of spaced annular ridges.
A boiler-tube having its end portion of reduced internal diameter, and provided externally of said end portion with annular grooves and an annular ridge between the grooves, the outer faces of the ridge and tube being substantially in the same plane; combined to this specification in the presence of two sub- With a tube-sheet provided with an opening scribing Witnesses. having in the Walls thereof an annular groove adapted to receive said ridge on expanding" HENRY LOWELL MQCULLOUGH' 5 the said end portion of the tube Within said lVitncsses:
