TUBE BXPANDER. No. 417,323. Patented Dec. 17, 1889.
W mm M w UNITED STATES PATENT OFFICE.
WILLIAM I). JOHN, OF SCRANTON, PENNSYLVANIA.
TUBE-EXPANDER.
SPECIFICATION forming part of Letters Patent No. 417,323, dated December 17, 1889.
Application filed April 24, 1889. Serial No. 308,401. (No model.)
To all whom, it may concern.-
Be it known that I, WILLIAM l). .ToHN, a citizen of the United States, residing at Scranton,in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Flanging-Tools; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention has relation to Hanging-tools for boiler-fines; and the object of the invention is to provide a tool for this purpose whereby the tube may be set or tightened in the tube-wheel preparatory to using the regular or usual tube-expander, so that the tube will be rigidly held in place while being ex panded; and to these ends the novelty consists in the construction. combination, and arrangement of parts of the same, as will be hereinafter more fully described, and particularly pointed out in the claim.
In the accompanying drawings the same letters of reference indicate the same parts of the invention.
Figure 1 is a view in perspective of my improved flanging-tool; and Fig. 2 is a longitudinal section of the same as it appears in use in the tube, with the end of the tube inserted in the tube-sheet.
A is the flanging-tool, and is composed of a series of four or more sections a a a a, the whole being held together by a circumferential spring B in the recess 1).
C is a longitudinal central orilice in which the taper drift-pin D is driven when the tool is being used.
E is an annular recess in which the end 6 of the tube E enters; and F is an annular shoulder which rests against the tubesheet G, so as to prevent the end e of the tube bottoming in the recess E.
H H are shoulders, one on each side of the recess 1, and when the tool is inserted and the pin' D driven in a flange is raised on the outside of the tube 011 each side of the tube-sheet, which effectually prevents the tube from rotating or moving backward or forward while being expanded in the tubesheet in the regular manner.
It will be observed in Fig. 2 that while the shoulder F isjagainst the tube-sheet the end of the tube does not reach to the bottom of the recess E. Therefore when the drift is driven in, the tube is not forced forward, as
the force of the blow given the drift is received by the tool itself, and its shoulder F, resting against the tube sheet, prevents the tool going forward and thereby carrying the tube with it, which would necessitate the services of a second man at the other end of the tube to hold and drive it back; but with my improved tool it will be seen that the only effect of the blow on the drift-pin is to spread the sections a a a a radially outward, and thus by means of the shoulders H H raise flanges on the outside of the tube on each side of the tube-sheet.
One of the essential features of my invention is the annular groove E, leaving an annular lip or abutment F, which serves as a positive gage when impinging against the tube-sheet G.
Another essential feature is the annular groove I in the reduced portion of the tool, having a'cylindrical shoulder H at one end and a rounded tapering shoulder H at the other end. By this construction the proper desired form can be given to the tube E without rotating the tool in the end of this tube.
It will thus be seen that with the aid of my improved tool one man is enough to do the work of two.
Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s
The within-described improved article of man ufacture. consistiu of a perforated flangingtool A, formed of several longitudinal segments a, a binding-spring B, seated in an annular recess formed in the enlarged eylindrical portion of the tool, an annular abutment F, an annular shoulder H, forming an intermediate annular groove E, a rounded and tapered annular shoulder II on the end of the reduced portion of the tool, and an annular groove between the shoulders H H, all as specified.
In testimony whereof I aflix my signature in presence of two witnesses.
WILLIAM I). JOHN.
