JOHN MCDERMOTT, OF DUBUQUE, IOWA.
TOOL FOR REAMING OUT AND TRIMMING PIPES.
SPECIFICATION formingpart Of Iietters Patent NO. 651,377, dated June 12, 1900.
Application filed April 10, 1899. Serial No. 712,564. (No model.)
To all whom it may concern:
Be it known that I, JOHN MODERMO'IT, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented new and useful Improvements in Tools for Reaming Out and Trimming Pipes; and I do hereby declare the following to be a full, 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 device relates to tools for reaming out and trimming pipes, with special reference to gas, steam, and water pipes; and it is the thought and purpose of this invention to provide a tool which shall be simple of construction and shall effectually and easily ream out or enlarge the bore of pipes or trim off or taper the outer edges of the same.
To this end it consists in a hollow frame provided with operating-handles and knives having cutting edges opposite to each other, the one cutting edge facing within the tool and the other without and adapted to attack the pipe on the inside and outside.
An exemplification of my device will be fully set out and described in the following specification and illustrated in the accompanying drawings.
Figure 1 is a perspective of my device, showing two cutters, each set in a stay. Fig. 2 is a plan View of my device with the cap removed. Fig. 3 shows a Vertical section of two of the cutters and the frame. Fig. 4 is a cross-section of a stay and one of the cutters therein. Fig. 5 is the same as Fig. 3 with pipe therein in positionto have its outer edges trimmed; Fig. 6, the same as Fig. 5 with pipe in position to be reamed or bored out, and Fig. 7 is a perspective of,one of the cutters.
Like letters of reference denote corresponding parts in each of the figures of the drawings.
In the drawings, A designates the frame, and a the operating-handles. In the frame are four holes, in each of which is inserted a cutter B, as shown in Fig. 2. To prevent these cutters from working loose or coming out when in use, there is secured to the frame A a cap D by the screws 0, as shown in Fig. 11
Secured to the under side of the frame A, and preferably integral therewith, are four stays E, which are set at an angle to the frame and converge to a common cen ter,where they are securely fastened together bya ring d or any other convenient mode of staying them rigidly at their ends. Thesestays E are open on each side at e sufliciently to allow the opposite edges of the cutter therein to project beyond the stays both within and without, as shown in Fig. 4.. In each of these stays E is inserted a cutter B, with the cutting corner or edges 72, projecting through the stays upon the inner side and the opposite cutting corner or edges 9 projecting through the stays upon the outer side for the purposes presently to appear.
I have shown the stays E as extending from the frame A to the ring at the entire length of the cutter but as the sole use of the stays is to hold the cutters rigidly in position it is manifest that numerous other modes of holding the cutter may be employed consistout with holding the cutters in the manner described, with one cutting edge facing outwardly and its opposite edge facing inwardly of the tool.
The cutters B are preferably of the shape of a-pyramid, with cutting edges g and h at each corner, the edge 9 facing out and the edge It facing in. It is manifest that the cutters may have onlytwo opposite cutting edges; but an advantage of four cutting edges is that when two of the edges become dulled the cutters may be removed and simply given a quarter-turn and reinserted without the dclay of grinding.
One or more reinforcing-stays H are attached to the sides of the stays E and hold them steady. At the bottom of the tool the corners are joined by a ring (I.
The mode of operating is substantially as follows: If the pipe is to be reamed out, the
tool is inserted in the end of the pipe, bringing the outer cutting edges 9 of the tool in contact with the inner edges of the pipe P. The operator then grasps the handles a and turns the tool around, thereby reaming out the inside of the pipe by the contact of the cutting edges g against the inner surface of the pipe P. If the pipe is to be trimmed upon the outer edges, the process is simply reversed and the pipe is inserted in the inner side of the tool, as shown in Fig. 5, bringing the outer surface of the pipe against the inner cutting edges h of the cutters. Then the operator by the handles turns the tool and pares or trims the outer edge of the pipe P.
It will be seen by making the cutters of a pyramid shape and inserting them in their stays, with two of their opposite cutting edges projecting out of the stays, the one within the tool and the other without, that a tool will be produced which will both ream out the inside of the pipe and trim off the outside. It is manifest also that any number of cutters may be used; but for all ordinary purposes four will be sufticient. A variation in the mode of holding the knives in position or their shape may be made without departing from the spirit of my invention.
Having now described my invention, what I claim, and desire to secure by Letters Patent, is-
1. A tool of the character described, consistin g of a frame with operating-handles, and having a central opening, movable angular cutters secured in the frame, with one of their cutting edges facing within, and the opposite cutting edge facing without the tool, and stays for holding the cutters in position, as and for the purposes shown.
2. In a tool of the character described, a frame, combined with a series of angular pyramidal tools which are attached to the frame at one end, and which have their sharpened edges to approach each other, and means for holding their sharpened ends in the desired relation to each other, substantially as specified.
3. In a tool of the character described, a circular frame having openings therethrough, and a series of angular pyramidal cutters which are connected at their larger ends to the frame, and which cutters are placed at an inclination so that their sharpened ends approach each other, combined with means for pressing the cutters in position, and means for fastening their sharpened ends together, substantially as set forth.
4. In a tool of the character described, an operating-frame provided with handles, and a series of openings through which the cutters are passed, and means for locking the cutters in position in the frame, combined with a series of angular pyramidal cutters which extend at an angle to the frame so that their sharpened ends approach each other, angular stays for each cutter secured to the frame, and means for connecting the sharpened ends of the cutters together, substantially as described.
In testimony whereof I affix my signature in the presence of two witnesses.
