PLUMBERS FERRU LE.

SPECIFICATION forming part of Letters Patent No. 494,413, dated March 28, 1893.

Application filed November 11, 1892. Serial No. 451,596- (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. COTTER, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certainlnew and useful Improvements in Plumbers Ferrules; and I do hereby declare the following to be afull, 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.

My invention has for its object to produce a novel article of the class known as plumbers ferrules, i. e. a ferrule used by plumbers in making'a connection between a lead pipe and an iron pipe, it being of course understood that it is impossible to form either a wiped or a packed joint between lead pipe and iron pipe without the interposition of'a' ferrule'made of some metal to which solder will adhere in making a wiped joint and which will not be affected by the pouring of molten lead in making a packed joint. Various styles of ferrules have been used heretofore for this purpose, the ferrule most commonly used however being one made of cast brass.

My novel ferrule is especially adapted to take the place of cast brass ferrules, it being very much stronger, much lighter, non-porous, and very much cheaper to produce.

In the accompanying drawing forming part of this specification the figure is a sectional view illustrating the manner in which a section of lead pipe is joined to a section of iron pipe by the use of my novel ferrule.

A denotes a section of lead pipe, B a section of iron pipe which is provided with the usual socketl at its end, said socket terminating in a shoulder 2, and C represents my novel. ferrule which is a drawn, seamless, brass or copper tube having at its lower enda flange 3 which rests upon shoulder 2 in the socket in the iron pipe. In joining a lead pipe to an iron pipe it is necessary that two perfect joints be made,for the reason that it is impossible to pour molten lead against a lead pipe without melting it.

The ferrule is in practice connected to the iron pipe by what is termed a packed joint.

The ferrule is placed in thesocket, the flange 9. The end of the piece of lead pipe is simply placed within the offset, resting upon shoulder 9, and a wiped joint formed in the usual manner covering the 'point 'of joinder of the lead pipe to the ferrule. For convenience in making the wiped joints, that is, so that they will alwaysbe ready forimmediate use, the upper ends of the ferrules are tinned as at 10, the lower edge of the tinned portion being indicated in the drawing bya line and the tinned portion above the line being indicated by lighter shading.

Ferrules made in this manner are very much lighter than any other style of ferrule known to the trade, making them much more convenient to ship and to handle, they are very much stronger for the reason that all tubing of the class from which these ferrules are made is tested to 500 pounds pressure before being shipped, and another and veryirnportant advantage is that there is no loss from breakage in dropping, cast metal ferrules being very apt to crack if dropped.

Having thus described my invention, I claim v In combination, with the iron pipe 13, the flanged ferrule secured thereto by a packed joint, an offset 8, formed at the opposite end of the ferrule, a lead pipe fitting within the same, and a wiped joint securing the ferrule thereto, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES A. COTTER.
