COILING LEAD PIPE.

SPECIFICATION forming part of Letters Patent No. 278,696, dated June 5, 1883,

' Application filed February 28,1883. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN FARRELL, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Manufacture of Lead Pipe and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to apparatus designed to prevent the flattening or distortion of lead pipe produced by winding it upon a reel into bundles or coils for subsequent handling or sale. This winding or coiling is done directly as the pipe leaves the machine by which it is formed. The pipe passes first over a large drum, usually of five or six feet in diameter, and

thence to the coiling-drum, which is much smaller in size, being usually about eighteen inches in diameter. The passage over the large drum does not injiu'e the pipe, because of the large diameter of the drum. The injury is done by the reel, which is necessarily small, in order to give the coil the proper size for handling and sale. I have discovered that, if the original shape of the pipe is preserved at the point where it encounters and begins to conform to the shape of the reel, it may be safely coiled without further danger of flattening or distortion. To this end, therefore, I have devised my present invention, which I will now illustrate by reference to the accompanying drawings, in which Figure l is a side elevation, partly in section, of my improved apparatus; and Figs. 2 and 3 are detail views.

The drawings illustrate parts of a form of press for making lead pipe, in which a is the presscylinder, having a cylindrical lead-chamber, a. This cylinder rests upon a supporting-block b, which has apassage, b, for a corerod, 0, and a concave socket, b forthe support of the core. The core a has a rod, 0, which lies in the passage 7), and a rounded or convex shoulder, c", which rests in the concave socket If. The core is centered by means of adj Listing-screws N, which extend in from opposite sides of the supporting-block b. The plunger (1 has a central bore, (1, for the pas: sage of the core 0 and of the pipe as it is forced out of the machine. In thelower end of the plunger is a die-socket, (Z for the reception wheel 71, heretofore spoken of, and in any "suitable position at the side of the same is the small drum or reel The pipe, after leaving the bore d of the plunger, is led around the drum h to the reel 2 upon which it is coiled into the bundles or coils before -mentioned. As stated, the effect of such coiling is to cause a flattening or distortion of the pipe, whereby it is reduced from around to a flattened or elliptical form in cross-section. This distortion is especially injurious to the larger and lighter grades of lead pipe, involves a waste I of money and material, and causes more or less trouble in plumbing operations. As before stated, my invention is designed to pre; vent this distortion.

To any suitable point on the frame m of the machine I fasten a wire rope or chain, a, which is of sufficient length to extend to the point upon the reel 43, where the pipe encounters and begins to bend around the reel. Herel fasten to the rope or chain, by means of eyes R, an inverted segmental trough, k, the circle of which is concentric to that of the pipe and of a size to fit snugly around it. The pipe is led over the drum h to the reel 2', where it is passed through the trough k, and then is coiled around the reel. The internal diameter of the trough being just sufficient for the passage of the pipe, there is no room for the latter to flatten out or enlarge laterally when passing through the-trough, the curved sides k of whichpreserve the shape of the pipe. As

before stated, the subsequent winding of the pipe up on the reeli past the point at which the trough 0 ends does not produce any injurious effect upon the pipe, so that I secure a coil of pipe which is perfectly round in cross-section, and obviate the difficulty of flattening, heretofore experienced. I do not limit myself to making round pipe in this way, but claim the use of the invention for any form which it is desirable to give the pipe.

I do not limit myself to the use of an inverted trough or guide, but claim any form of external device which, encircling or placed at the sides of the pipe, will prevent or oppose the increaseof the diameter of the pipe in a direction parallel to the face of the coiling reel or drum. If desired, such external device may be supported in a frame and capable of being brought down into the proper position It is not neces-.

ox er the upper side of the reel. sary therefore that it be attached to the leadpipe machine, as shown in the drawings; nor is it necessary that the pipe should pass directly from the machine to the reel, as it may be drawn out upon the floor, and subsequently reeled. This makes no difference with my improvement, as it is used and applied only when the reeling operation takes place.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a press for forming lead pipe and a reel or drmn for coiling the same, of a trough or guide operating on the exterior of the pipe at or about the point where it is bent in reeling or coiling, substantially as and for the purposes described.

2. The combination, with a reel ordrum for coiling lead pipe, of a trough or guide operating on the exterior of the pipe at or about the point where it is bent in reeling or coiling, substantially as and for the purposes described.

3. The method of preserving the shape of lead pipe during the operation of coiling, consisting. in passing it between external surfaces at or about the point where it is bent to conform to the curve of the reel to prevent its extension in a direction at right angles to the plane in which it is bent, substantially as and for the purposes described.

I11 testimony whereof I have hereunto set my hand this 23d day of February, A. D. 1883.

JOHN FARRELL.
