TUBEeSTOPPER.

SPECIFICATION forming part of Letters Patent No. 282,006, dated July 24, 1883, Application filed April 13, 1883.

To @ZZ whom, t may concern:

Be it known that I, DAVID JOI-IN MORGAN, a subject of the Queen of England, residing at Cardiff, in the county of Glamorgan, England, have invented a new and useful Improvement in Tube-Stoppers, of which the following is a specification.

My invention relates to a means for stopping the efflux of steam, water, or other liquid or gas in a state of pressure from a burst or collapsed tube as fitted in multitubular marine boilers. My improved device or appliance comprises certain novel features of constructionhereinafter claimed, which adapt it to be so applied by the operator that he may be protected from said efflux during repair.

A sheet of drawings accompanies this specification as part thereof.

Figures l and 2 of these drawings represent longitudinal sections of my tube-stopper, the latter illustrating a preferred modification. Fig. 3 represents perspective views of the rcspective ends of the same, and Figs. 4 and 5 represent, respectively, a longitudinal section ofthe middle portion of the main tube ofthe stopper, and an elevation of the key-rod or tube, illustrating additional modifications.

Like letters of reference indicate corresponding parts in all the figures.

The known part of this appliance comprises atube, A, slightly longer and of smaller diameter than the burst or collapsed tube, and provided with an outside `screw-thread at each end, upon which are fitted nuts B O D E-a pair at each end-between which elastic collars or packing-rings G G, of india-rubber or other suitable material, are squeezed out and expanded, so as to close the ends of the burst' One of the said nuts, B-viz., that farthest from the operatoris made with a bridge, B', pierced with a square or other cornered hole, into which the end of a key-rod orl tube, H, fits and keys, so that the nut can be rotated by the key-rod when passed through the tube A from the end nearest to the operator.

The mode of operation is as follows: The nuts D and E, with. the packing-ring G be- (No model.)

tween them, are first adjusted and locked by their jam-nut F upon the near end of the tube A, (which is screw-threaded for some distance to allow of such adjustment,) so that the packing-rings G G are respectively in proper position to occupy the ends of the burst or collapsed tube. The nut E, which is provided with a lug, E', so that it cannot be thrust inadvertently too far into the tube, is iii-st screwed up, so that the end of the burst tube nearest to .the operator is first stopped, and the efflux of steam and water diverted to the other end, away from the operator. By inserting the key-rod H through the tube A, and turning said key-rod by a wrench or bar applied tothe square head or holes provided for this purpose, the nut B can now be readilyT tightened up, so as to make the farther joint steam-tight, and thus repair the burst or collapsed tube.

The packing-rings G G may be made of a ductile or fibrous material-such as lead or asbestus-by constructing the same of V shape in cross-section, or with funnel-shapedends, and making the nuts B O D E with coneshaped or wedging faces presented to and pressing into the vends of said packing-rings, so as to expand the same more powerfully, as shown in section in Fig. 2 and in perspective in Fig. 3. Vhen india-rubber or other packing offering considerable rubbing friction is employed, I insert a metallic washer, K, between the packing and the nuts B and E, so as to enable the latter to turn easily.

I may make the tube A in two pieces united by a screw-joint, as in Fig. 4, and the keyrod H in two parts linked together by eyes, as in Fig. 5, to suit short stoke-holes when necessary.

Having now fully described my said tubestopper, I disclaim as old the combination, with said tube A, of packing-rings and expanding nuts, and also the construction of said nuts with conical faces, and the packingrings of correspondingshape, broadly considered.

I claim as my invention- 1; The combination, with au expanding tube-stopper, of an internal rod or tube en- DAVID JOI-IN MORGAN, OF OARDIFF, COUNTY OF GLAMORGAN, ENGLAND.
