TRENCH-PIPE CUTTER.
Specification of Letters Patent.
Patented May 26, 1908.
Application filed. July 29, 1907. Serial No. 386,166.
To all whom it may concern:
Be it known that 1, JAMES E. MOORE, a citizen of the United States of America, residing at Boise, in the county of Ada and State of Idaho, have invented certain new and useful Improvements in Trench-Pipe Cutters, of which the following is a specification.
This invention relates to new and useful improvements in pipe cutters and has relation more particularly to that class of cutters known as ratchet cutters.
It is an object of this invention to provide a novel device of this character which can be readily applied in operative position in a trench or other difficult location.
It is, furthermore, an object of this invention to provide a novel device of this character which will be simple in construction, efiicient and advantageous in practice, and economical to manufacture.
With the above and other objects in view, the invention consists in the details of construction and in the novel arrangement and combination of parts to be hereinafter-more fully described.
In describing the invention in detail, reference will be had to the accompanying drawing forming part of this specification, Wherein like characters of reference denote corresponding parts in the several views and in view in elevation illustrating in fragment a detail of the invention; Fig. 6, is a view in elevation of the invention in applied position, the pipe to which it is attached being in fragment; and Fig. 7, is a fragmentary view in elevation of another detail of the invention.
In the drawings 1, indicates the retaining or positioning ring which is formed in segments hinged one to the other, as at 2, and held in position when applied by a hasp 3, secured to a lug 4, on one of the segments and embracing a lug 5, on the next succeeding segment. It is to be observed that these lugs 4 and 5 abut, and thereby provide a rigidity to the entire ring. The asp 3, is held against displacement when in o erative position by a set screw 6, which is t readed through the end of the hasp and engages the lug 5. While it has been stated that this ring 1, is formed of a multiplicity of segments, it has been found in practice best to employ but two, as fully shown in the drawings. This ring is caused to embrace a pipe to be out adjacent the cut and is retained in such position by the set screws 7, which are threaded therethrough and bind against the pipe, as fully set forth in Fig. 3
The cutter ring is likewise formed in sections hinged one to the other, and held in operative osition in a manner similar to that described with relation to the retaining ring. Each of the sections is formed of two segments 8 and 9, the periphery of the segments 9, being toothed. The flanges at their ends are held in position by bolts 10, passing through the segments and the interposed blocks 11. These blocks 11, hold the segments 9 and 10 suitably spaced.
Positioned between one of the segments of the cutter ring adjacent the ends thereof, are the angular plates 12, approximately U- shaped in elevation. These plates are held in position by the pins 13, which pass therethrough and through perforations 14, in the segments. Attention is directed in this re spect to Fig. 1, where it will be observed that there are series of alining apertures 14. This is done to permit adjustments of the plates 12 for a purpose which is believed to be clearly apparent to those skilled in the art to which this invention appertains.
Pivotally secured to an end of each of the plates 12, is an arm 15, provided with a cen tral o ening 16, in which is mounted the cutting disk 17. The end of the plate 12 adjacent the free end of the arm 15, is rovided with an inturned portion 18, to llmit the movement of the arm. It is here to be observed that the arm 15, is allowed a certain freedom of movement, which when the cutter ring is being rotated, will' prevent the same from binding on the pipe w ich is being cut.
Interposed centrally of the remaining section of the cutter ring, is an approximately segmental plate 19, having threaded therethrough midway its length, the screw 20.
Pivotally suported by the segments, and positioned therebetween, is an arm 21, carrying a cutter disk 22. It is to be noticed that this cutter disk 22, is on a plane approximately midway of the cutters carried by the arms 15. The screw 20, bears against the arm 21, and is for the purpose of compensating for the cut made in the pipe The cutter ring is placed upon the pipe to be cut adjacent the retaining ring 1, with the toothed flange 9, adjacent thereto and prei erably contacting therewith. Projecting upwardly from one of the sections of the retaining rings 1, is a lug 23, to which is pivotally secured an operating lever 24. To this lever 24, is pivoted a lug 25, having the diverging teeth or projections 26, extending therefrom. Either of these extensions engage the teeth of the flange 9, and upon the necessary movement of the lever 24, imparts a rotary movement to the cutter ring, as will, it is believed, be fully a preciated. It is thought that it is obvious tlliat the diverging teeth or projections 26, ermit the cutter ring to be rotated in either c irection.
I claim:
1.v In combination, a cutter rin c0mprising spaced rings, means for uniting said rings, plates secured between the rings, an arm pivoted to each plate, and cutting means carried by the arm.
2. In combination, a cutter ring comprising spaced rings, means for uniting said rings, plates secured between the rings, an arm pivoted to each late, cutting means carried by the arm, an means for limiting the movement of the arm on its pivot.
3. In combination, a cutter ring comprising spaced rings, means for uniting said rings, plates secured between the rings, an arm pivoted to each plate, cutting means carried by the arm, and means carried by the plate for limiting the movement of the arm on its pivot.
4. In combination, a cutter ring, comprising spaced rings, means for uniting said rings, plates secured between the rings, an arm pivoted to each plate, cutting means carried by the arm, and means for adjusting the plates with relation to the inner periphery of the cutting ring.
In testimony whereof I afiix my signature in the presence of two Witnesses this 15th day of February, 1908.
JAMES E. MOORE.
