Lagers Parent No; 91,261, zaad June 15,1869.
The Schedulefrafened' to'in than Letten Patent and making part of the nm.
To all whom it 'ma/y concern:
Be it known that I, WILLIAM BARRY, of Chicago, in the county of Cook, and State of Illinois, have invented an Improved Tool for Ohucking, Reaming, and
Squaring Pipes; kand I do herebydeclare that the following is a fulland exact description thereofireference being had to the accompanying drawings, and letters marked thereon, making a. part of this description, in which- Figure 1 is a perspective representation ofthe improved tool.v
Figure 2, angelevation of the same.
Figure 3, a' verticalseetion.
Figure 4, a perspective representation of the bit for squaringthe end of apipe, removed from the stock of the tool.'
Figure 5, a view oflthe bit for reaming out the end of'. a pipe, and the key which holds it inthe stock.
The nature of the present invention consists in the novel construction and combination ofthe reaming and squaring-bit, together with the stock in which they are tted.
A represents a cylindrical stock, which hasA a shank, G, arranged to fit in a'lathe, and a mortise through it, to receive a bit, B, with which the end of a pipe is squared. v
It also has a mortise made through it near the end, to receive the bit E, which reams out the pipe.
The bit B is made of steel, and it is so notched out at b as to lock over the end of the mortise, whenit is secured by the key D, as shown at figs. 1 and 3, and it is provided with cutting-edges 0, for squariug the end of a pipe, and also with a small reamer, n, fitting closely against the stock A, to ont away the inner al1- gllle of the pipe, so that when a screwthread is cutvon t e inner periphery ofthe latter, the metal will not `be so raised as to prevent the squared ends of two-pipes from ittiug closely together.
The bit E is provided with a shank, 1li/,which isput through the stock A, and fastened with a key,l J. y
The'stock A being. cnt away at F, allows the bit E to cut the required depth without being choked.
Opa/ration.
The end, Gr, of the stock A, is to hesecured to the lathe in the usual manner, and the pipe to be squared and reamed placed in a mandrel, or otherwise held in Y WILLIAM BARRY.
