Letters Patent N 99,402, dated February 1, 1870.
IMPROVEMENT IN MACHINE FOR FORMING- SHEET-METAL TUBING.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern.-
Be it known that I, Mon'rm'nn M. CAMP, of New Haven, in the county of New Haven, and State of Connecticut, have invented a new Improvement in Machine for Foi-ming Sheet-Metal Tubing; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exa'ct description of the same, and which said drawings constitute part of this specification, and represent, in
Figure 1, a front view Figure 2, a top view Figure 3, a side view of one length of tubing formed in the machine;
Figure 4, a sectional view of the same; and in Figure 5, a sectional view illustrating the object of my invention.
This invention relates to an improvement for forming joints of inetal'tubing or pipe, such as are commonly used for lining cement-pipe.
One end of each length is required to be enlarged, as-seen in fig. 4, so that the end of the next section will enter therein, as seen in fig. 5.
Heretofore this has been done by first forming the tubing, and then hammering or stretching the end until it will permit the insertion of the next section, a tedious process, which, by my invention, is entirely overcome; and consists in forming one of the rolls of a set, with a shoulder or larger diameter at one end, and the other roll of a correspondingly less diameter at the same end, so that the sheet of metal passing between the rolls enlarges, a portion of one depresses the metal into the diminished portion of the other, and thus forms a shoulder, so that when the tubing is formed, one end is enlarged sufficiently to receive the reverse end of the same section.
- A is one roll'of a set, B and B the other two, all
arranged in suitable bearings, C, so as to be adj nstable in the usual manner.
One of the rolls, A, is enlarged, as at D, at one end, so as to form a shoulder, a. correspondingly reduced, as at E,.so as to form a reverse shoulder at (l, and the rolls geared together so as to operate in the usual manner.
The sheet of metal is inserted between the rolls A and B, so-that one edge will run close to the ends 1) and E of the rolls. Therefore, as the metal passes through the rolls, to be curved into cylindrical form, it is at the same time depressed at one end of the en larged portion D so as to form it into shape, as seen in figs. 3 and 4, and form a shoulder, f, the portion beyond the shoulder toward the end being enlarged by so much of the thickness of the metal that the reverse end of a second piece, G, will enter and fit closely the enlarged portion, as seen in fig. 5.
It will be seen that no additional time is required to form the shoulder or enlarged portion, inasmuch as the sheet-metal must be run through the rolls to bring itinto proper cylindrical form; hence all the time'which has heretofore been required for fitting the ends together is saved, and while the invention is specially designed for making tubing for cement-pipe,-it is alike applicable for other cylindrical tubes, as water conductors, steam-pipes, stove-pipes, 85c.
I am aware of the patent of J. T. Farrand, June 15, 1852, and do not wish to be understood as clairning anything therein described. I claim, as my invention-- The rolls A, B, and B, constructed and arranged as described, and for the purpose specified.
