EDWARD MOGOVERN, OF ONEONTA, ASSIGNOR OF ONE-HALF TO ROBERT C. BLAOKALL, OF ALBANY, NEW YORK.
SECURING BOILER-TUBES.
SPECIFICATION forming part of Letters Patent No. 234,312, dated November 9, 1880. Application filed March 22, 1880. (No model.)
To all whom it may concern:
Oneonta. in the county of ()tsego and State of New York, have invented a new and useful Device for Securing the Ends of Tubes in Steam-Boilers and other Structures, of which the following is a full and exact description.
My invention consists of a metallic sleeve of a slightly-tapering exterior form, provided with an annular flange and adapted to fit on the outer diameter of the tube, and of a ductile metal bushing interposed between the tapered surface of said sleeve and the tube-hole in the tube-sheet.
The object of my invention is to provide a reliable fastening for the ends of boiler-tubes, water-grate bars, &c.
In the accompanying drawings, which form a part of this specification, and to which reference is herein made, Figure 1 is a side elevation of the end of a boiler-tube secured by my device, the tube-sheetan d bushing being shown in section; Fig. 2,-a longitudinal section of the sleeve; Fig. 3, an end view of same, and Fig. 4 a side elevation of my device as applied to the tubes of water-grate bars.
A is the tube; B, the tube-sheet in which the tube is fastened; G, the fastening-sleeve; D, the bushing.
The boiler-tube A may, when desired, be fastened at one end to one of the tube-sheets by any of the old and well-known modes, and at the opposite end it may be secured by my fastening.
When my device is used on old tubes that are to be restored to their places in an old boiler where the holes for receiving them cannot be readily enlarged, the end of each tube should be swaged down to allow sufficient space between the tube and the hole in the tube-sheet to receive the sleeve and bushing.
The fastening-sleeve O is usually made of wrought-iron. The bore of each is of a uniform size and should fit the external surface of the tube on which it is used. As usually made the tubular portion of it is one and three-fourths inch long, and it is tapered on its outside about one thirty-second of an inch on each side in that length. At its larger end it is provided with an annular flange, c, which,
| when the sleeve is driven home, bears against Be it known that I, EDWARD MoGovERN, of
the flange produced on the bushing and holds it against the face of the tube-sheet B. The outer end of the bore of the sleeve is chamfered to form the countersink 0, into which the end of the tube should be upset or riveted to hold the sleeve more securely in place.
In the tubular part of the sleeve a fine longitudinal slit, is made, which extends from the smaller end of the sleeve and terminates near the flange c, the distance from said flange being equal to about one-half the thickness of the tube-sheet. The object of said slit is to facilitate the placement of the sleeve and permit the same to either enlarge or compress, as occasion may require, when it is driven to its place.
The bushing D is made of copper or other equally ductile metal. It is cylindrical in form, and is interposed between the hole in the tube-sheet B and the sleeve 0 in such manner that by the act of driving in the sleeve the outer end of the bushing is expanded to form thereon an annular flan ge, d, which remains between the flange of the sleeve and the tube-sheet. At the same time the tubular part of the bushing becomes compressed to form a tight joint with the tube-sheet and sleeve, and the sleeve 0, by reason of the slit 0 is compressed to form a tight joint with the tube.
In constructing water-grates in boilers with internal fire-boxes one end of the tube may be screwed into the tube-sheet at one end of the fire-box, and at the opposite end my device may be used for the fastening. In such cases the sleeve 0 and bushing D arefirst slipped onto the tube A, and theend on which my device is used is passed into the hole prepared for my fastening, after which the screwed end of the tube may be inserted and secured in its place, and then the sleeve and bushing are driven in to complete the fastening of the tube. When applied in the manner last described, the flanged end of the sleeve is placed toward the middle of the tube, as shown in Fig. 4.
I claim as my invention- 1. As a device-for securing the ends of tubes in tube-sheets, the taper sleeve 0, arranged on the outside of the tube, and provided with a tile bushing D, as and for the purpose herein flange, r, and slit essentially as herein specified.
specified. I 2. The combination, with tube A and tubc- 5 sheet 1 of the taper sleeve C, arranged on the outside 01' the tube, and having a flange, 1 \YILLIAM II. LOW, c, and slit as herein described, and the duel \YILLIAM II. SEWARD.
EDWARD MCGOVERN.
