PERCY HARRISON, OF BALTIMORE, MARYLAND, ASSIGNOR TO HARRISON SPECIALTY COMPANY, A CORPORATION OF MARYLAND.
PLUG FOR BOILER-TUBES.
Specification of Letters Patent.
Patented Nov. 21, 1916.
Application filed May 24, 1916. Serial N 0. 99,497.
To all whom it may concern:
Be it known that I, PERCY I'IARRISON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improve ments in Plugs for Boiler-Tubes, of which the following is a specification.
This invention relates to improvements in plugs to stop leaks in boiler tubes, and has for its object to provide a simple and eflicient device whereby a leak in one or more of the tubes of a boiler may be stopped temporarily or until the same can be repaired or replaced, the device being so constructed that it can be readily inserted into the tube and when in the desired position will automatically adapt itself to the size tube in which it is placed.
The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more particularly set forth in the following specification and pointed out in detail in the appended claims.
In the accompanying drawing,Figure l is a side elevation of my improved plug, showing the position of the sections before being inserted in the tube. Fig. 2 is a view of one end of Fig. 1 with the washers removed. Fig. 3 is a view of the opposite end. Fig. 4 is a sectional view of a tube, with the tubes in the ends thereof, showing the position of the sections of the plugs after they are in position and in contact with the steam or hot water.
Referring to the accompanying drawings, forming part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, 1 designates the outer sections of the plug which are tapered transversely and which, when fitted together have a tapering opening through the center the entire length of the plug into which is fitted the tapering core, 2, which latter is provided with a central aperture 3 for the reception of the rod, 4 which is provided with an eye, 5 at one end and a collar, 6 near said eye. Mounted on one end of the rod 4 is a washer, 7 which is held against the end ofthe plug by the nut 8, another washer, 9 is mounted on the rod, 4, at the opposite end of the plug, and a spring, 10 surrounds said rod 4 between the washer, 9 and the collar 6 and is normally under tension.
lVhen the plug is made up the parts are held in the position shown in Fig. l by glue, or other suitable, adhesive substance that will dissolve in hot water or steam, so that when the plugs are inserted in the tube and placed in position therein the contact of the hot water or steam will dissolve the substance holding the parts of the plugs and the springs, 10 will force the sections and the core 2, to the position shown in Fig. 4, thus automatically adapting themselves to the size of the tube. The plugs being formed of soft wood will then swell and hermetically seal the said tube. The rods 4 are connected by a rod 11 of suitable size.
Having thus described my invention, what I claim is:
1. A plug comprising a plurality of tapered sections, a tapering core fitted within said sections, and a rod extending through said core.
2. A plug comprising a plurality of tapered sections, a tapering core fitted within said sections, a rod extending through said core, and a spring exerting its tension against one end of said core.
8. A plug for boiler tubes comprising a plurality of tapered sections, a tapering core fitted within said sections, a rod extending through said core and having a collar near'one end thereof, and a spring between said collar and the end of said core.
4. A plug for boiler tubes comprising a plurality of tapered sections, a tapered core fitted within said sections, a rod extending through said core and having an eye on one end and a collar adjacent said eye, a washer mounted on said rod and impinging against one end of said core, a spring between said washer and said collar, and a washer at the opposite end of said plug.
In testimony whereof I aflix my signature in presence of two witnesses.
PERCY HARRISON.
