ROBERT CLARKE, OF GRAVESEND, NEW YORK.
PIPE-COUPLING FERRULE.
SPECIFICATION forming part of Letters Patent No. 391,946, dated October 30, 1888.
Application iiled August 9, 1887.
To @ZZ whom it may concern,.-
Beit known that I, ROBERT CLARKE, a citizen of the United States, and a resident of' Gravesend, Long Island, Kings county, New York, have invented cert-ain new and useful Improvements in the Art of Making BelllndedTubes, of which the following is a specifxcation.
This invention has relation to an improvement in the art ofrnakingbell-ended tubes,teeh nically termed ferrules or nipples/7 which are adapted for use in coupling lead pipes to iron or other sewer-pipes. Heretofore it has been customary to use a coupling-nipple consisting of an iron tube having a leaden coating pressed or cast thereon; but it has been found that there are certain disadvantages incident to such coupling ferrules or nipples from the fact that unless great care is used when the ferrnle is being` calked the lead covering becomes melted by the molten lead used for lling the space between the nipple and the enlarged mouth of the pipe in which it isinserted. Another disadvantage which is often experienced is that the iron lining-tube sometimes becomes broken when the ferrule is heavily calked; but by reason of this iron tube being inside the ferrule it is impossible to detect such break, and hence obstruction ensues when the pipeis in use. To overcome these defects, ferrules or coupling nipples having the iron tube on the outside of the body of the pipe, with a part turned over onto the iron,have been used; but prior to my invention such coupling devices have been made by hand-an operation which is both tedious and expensive.
My invention pertains to a novel process of making coupling-ferrules of the latter-described constrnction in a rapid and cheap manner.
In the drawings, Figure l is a side view of a eoupling-ferrule made according to my invention, parts being broken away to better illustrate its construction. Fig. 2 illustrates one stage in the process of manufacture before completion. Fig. 3 is a side View of' a bent or curved coupling-piece.
In the drawings, A represents a short sec- Serial No. 246,525. (No model.)
tion of tube of iron, brass, or otherhard metal, and B represents the lead portion of the ferrule, it being on the inside of tube A and projecting in one direction sufficiently far to permit proper connection with the lead pipe, the other end being spun over the end of the pipe A, which is enlarged or provided with a flange, a, at this point to prevent separation of the parts.
In the manufacture of a coupling-ferrnle according to my invention the lead portion B is first properly placed within the tube A, as seen in Fig. 2, by any suitable means, as by pressing or casting, preferably by the former process. rIhe projecting end b of lead tube B, which is in proximity to the flange or bead a of the hard-metal tube B, is then spun over said flange, completing the article shown in Fig. 1.
I do not Wish to be limited to any particular A apparatus by which my invention may be worked, as any well-known or specially-devised machinery or tools may be used in carrying it out.
I do not in this case claim the article herein described and illustrated in the drawings, but reserve to myself the right to make the same the subject of another application.
What I claim isw The herein described improvement in the art of making bell-ended tubes,the same consisting in first securing a lead tube or cylinder on the inside of a shorter hard-metal tube having an end rib or flange with the lead tube projecting beyond both ends of the hard-metal tube, and then spinning one end of the lead tube over the ribbed end of the hard-metal tube and onto the upper surface of said latter tube, whereby the one tube is confined immovably to the other.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ROBERT OL ARKE.
