UNITE STATES ATFNT FIG.
FRANK A. HEADSON, OF LAFAYETTE. INDIANA, ASSIGNOR TO HEADSON TOOL & MANUFACTURING COMPANY, OF LAFAYETTE, INDIANA, A COR- PIPE-CUTTING TOOL.
Specification of Letters Patent.
Patented Oct. 1'7, 1905.
Application filed January 18, 1905. Serial No. 241,709.
To (1.7/7 whom it 721/0 1 concern: v
Be it known that I, FRANK A. I-IuADsoN, a citizen of the United States, residing at Lafayette, in the county of Tippecanoe and State of Indiana, have invented certain new and useful Improvements in Pipe-Cutting Tools, of which the following is a specification.
My invention relates to that class of pipecutting tools having a main frame provided with a cutter or cutters and means for forcing such cutter or cutters into operative engagement with the pipe to be operated upon and having rolls adapted to engage pipes of various sizes to hold the device in operative position with relation to the pipe during its operation.
The principal object of my invention is to provide a simple, economical, and efficient pipe-cutting tool.
A further object of the invention is to provide a pipe-cutting tool with means for enabling a larger variety of sizes of pipes to be out than is possible where only two rolls or bearing-points are adapted to engage the pipe to hold it between such rolls or bearing-points and the cutter or cutters.
A further object is to provide a pipe-cutting tool having rolls adapted to hold pipes of relatively small sizes in position with relation to the cutter and having additional rolls adapted to cooperate therewith in holding larger pipes than can be successfully operated upon by means of such small pipeguiding rolls, whereby such pipe-cutting tool may be employed for cutting a large variety of sizes of pipe, such as would require more than one cuttingtool of the ordinary type to successfully cut.
Other and further objects of the invention will appear from an examination of the drawings and the following description and claims.
The invention consists in the features, combinations, and details of construction hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a view in elevation of apipe-cutting tool constructed in accordance with my improvements, showing a pipe of medium size in full lines and a smaller pipe in dotted lines in position tovbe operated upon; Fig. 2, a similar view, partly in section, showing a pipe of medium size in full lines and a relatively large pipe in dotted lines with the relatively adjustable rolls shown in dotted lines in position to engage the large pipe and such rolls in full lines in position to engage the pipe of medium size.
In constructing a pipe-cutting tool in accordance with my improvements I provide a gagement with the stem or shank portion of the main frame of the device. The outer end of this threaded rod is provided with a handle e, by means of which the rod is turned in either direction for adjusting a cutting disk or tool f and forcing it into operative engagement with the pipe to be operated upon. The cutter disk or tool f is movably connected with the main frame upon the swinging end of a pivoted frame or arm g, which is pivotally attached by means of a pivot h to the main frame, such cutter disk or tool being pivotal] y mounted in the swinging end of such pivot frame or arm by means of a journal 6, upon which the cutter-disk rotates. A plurality of suitable pipe-engaging rolls is are provided and mounted in the hook portion of the main frame, so as to engage the pipe to be operated upon and resist the pressure applied to the reciprocating cutter disk or tool. It is very desirable that these rolls which serve to guide the pipe with relation to the reciprocating cutter and roll down the burs should be so constructed and arranged as to permit a relatively small pipe to be engaged between the rolls which are nearest to each other and to the reciprocating cutter and that pipes of various and much larger diameters be engaged, preferably, by the entire set of rolls which serve as guides while the tool is in operation. In order to accomplish this, the rolls k are mounted, preferably, in adjustable relation to each other. They are also in adjustable relation to the main frame and the reciprocating cutter. To accomplish this, a pair of supplementary swinging frames Z are each pivotally mounted upon the hook orjaw portion of the main frame, to which they are secured by means of lugs m and pivots n, which extend through such lugs and swinging or pivoted frames. The pipe-engaging rolls k are all rotatably mounted in these frames upon suitable journals 0, so that they project beyond the pivoted frame sufficiently to engage the pipe to be operated upon. One or more of these rolls in may be provided with a cutting-disk portion p for cutting the pipe to be operated upon. They, however, serve as guide-rolls for guiding the tool duringits rotation around the pipe in operation or during the rotation of the pipe with relation to the tool while such pipe is being operated upon. They also serve to depress or roll down the bur which would otherwise be left upon the pipe after being cut by the reciprocatinglymounted cutter disk or tool. By this arrangement it will be readily seen by those skilled in the art that the guide-rolls which are nearest to each other are adapted to hold a very small pipe between them and a reciprocating cutting-disk or cutter; and that when a pipe is to be cut which is large enough to extend to the guide-rolls most remote from each other such pipe will be engaged not only by the outermost rolls, but by all of the rolls mounted in the swingingframes. The adjacent ends of the swinging or pivoted frames in which the rolls ii? are mounted have base or shoulder portions q, adapted to engage the main frame when the limit of movement of the inner end of such frames is reached and hold the inner rolls in operative position against the pipe while it is being subjected to pressure from the reciprocating cutter. The outer ends of these frames are provided with similar base or shoulder portions r, also adapted to engage the main frame and hold such outer rolls firmly when the extreme limit of movement of the outer rolls in a direction away from the reciprocating cutter-disk is reached. In all intermediate positions of the swinging frames and the rolls mounted therein the frames are so adjustably held as to readily yield to conform to the size of pipe being operated upon, and yet they provide a sufficiently-rigid resistance to the pressure applied to the pipe by the reciprocatingly-mounted cutter to efficiently and positively resist such pressure and guide the tool in its operation. They at the same time permit the movement of the tool with relation to the pipe with the minimum amount of frictional resistance to such movement.
I claim 1. In a pipe-cutting tool, the combination of a frame, a cutter mounted therein, and a plurality of sets of pipe-engaging rolls mounted in adjustable relation to the frame and cutter. 2. In a pipe-cutting tool, the combination of a frame, a cutter mounted therein, means for operating the cutter, and pipe-engaging rolls mounted in adjustable relation to each other. 3. In a pipe-cutting tool, the combination of a frame, a cutter reciprocatingly mounted therein, means for operating the cutter, and pipe-engaging rolls mounted in adjustable relation to such cutter and to each other.
4. In a pipe-cutting tool, the combination of a main frame, pipe-cutter mechanism mounted in movable relation thereto, pipe-engaging rolls, and supplementary frames movably mounted in the main frame and supporting such pipe-engaging rolls.
5. In a pipe-cutting tool, the combination of a main frame, a cutter mounted therein, supplementary frames pivotally mounted upon the main frame, pipe-engaging rolls pivotally mounted upon such pivotal supplementary frames, and means for operating such pipecutter.
6. In a pipe-cutting tool, the combination of a main frame, a cutter mounted therein, a plurality of supplementary frames pivotally mounted upon the main frame, and a pair of pipe-engaging rolls rotatably mounted in each of such supplementary frames.
7. In a pipe-cutting tool, the combination of a frame, a plurality of cutters movably mounted with relation to each other, and a plurality of pipe-engaging cylindrical rolls mounted in adjustable relation to such cutters.
8. In a pipe-cutting tool, the combination of a frame, a plurality of cutters mountedin movable relation to such frame and to each other, and pipe-engaging cylindrical rolls mounted in adjustable relation to such cutters.
9. In a pipe-cutting tool, the combination of a main frame, a plurality of supplementary frames pivotally connected thereto, and cutter-rolls and cylindrical pipe-engaging rolls mounted in such supplementary frames in adjustable relation to each other.
10. In a pipe-cutting tool, the combination of a frame, a cutter reciprocatingly mounted therein, a plurality of outer pipe-engaging rolls for engaging the pipe to be operated upon, a plurality of pipe-engaging rolls rotatably mounted intermediate such outer pipeengaging rolls for engaging pipes of sufficiently small diameter to pass between such outer rolls and a plurality of supplementary frames movably supporting such rolls.
