1 Claim. (Cl. 30-102) This invention relates to a pipe cutter and it consists in the constructions, arrangements and combinations herein described and claimed.

It is an important object of the invention to provide a pipe cutter wherein one cutter mount is stationary, while the opposed cutter mount is slidable with respect thereto upon rotation of a screw operatively connected to the slidable cutter mount, to thereby draw the slidable cutter mount into engagement with a pipe interposed between said cutter mounts.

It is also an important object of the invention to provide a pipe cutter wherein a slidable cutter mount is drawn into operative engagement with a fixed cutter mount by means of a rotatable screw which is held fixed against longitudinal movement outwardly of the cutter body thereby enabling the use of the cutter in restricted areas.

It is a still further object of the invention to provide the operating screw at one end with a socket for reception of a wrench of substantial length to increase the leverage and thus provide a fast production cutter.

A still further object of the invention is the provision of a pipe cutter wherein a plurality of spaced wrenchreceiving sockets are inherent enabling the rotation of the cutter from various positions, which is desirable when the cutter must be operated upon pipes in close relation to one another.

Additional objects, advantages and features of invention will be apparent from the following description, considered in conjunction with the accompanying drawings, wherein,

Figure 1 is a top plan view of the pipe cutter in operative position upon a pipe.

Figure 2 is an edge view of the cutter.

Figure 3 is a top edge view thereof.

Figure 4 is a cross section on the line 44 of Figure 1.

Figure 5 is a vertical section through the cutter.

Figure 6 is a side elevation of the operating handle for the cutter.

Figure 7 is a fragmentary portion of the handle as viewed on the line 7--7 of Figure 6.

Figure 8 is a top plan view of the pipe cutter installed upon a pipe surrounded by a series of other pipes.

Figure 9 is a similar view illustrating the rotation of the cutter about the pipe, and

Figure 10 is a top plan view of the cutter, with the operating handle engaged in the socket of the screw.

Referring to the drawings, a pipe cutter is generally indicated by the reference character 10 comprising a main body 11 having an integral jaw 12 and a slidable jaw 13, the jaws being arranged in opposed relation. The jaws 12 and 13 are formed with concave inner faces 14 and convex outer faces 15 and the ends 16 of the jaws are preferably rounded so as to avoid angular corners.

The rigid jaw 12 extends substantially at right angles to the body 11 and is formed with an elongated slot 17 as best seen in Figures 4 and 5 and within the slot there "ice is' mounteda pair of spaced cutter disks 1'8 fre'ely rota-t able upon respective shafts 19' extendingtransversely of the slot 17.

The -slidable-jaw 13'isa1soformedwith a'slot 20 for rotatably mounting' a cutter disk 21-by meansof a shaft 22 extendingtransversely-of the slot. It should be noted' that the shaft 22 is positioned in vertical alignmentwitli the longitudinal axis of the pipe 23 engaged between the cutter disk 18 andi21l The main body 11 is formedwith a machined bore 24 formed with a concentric enlarged annular passage 25 of a length greater than the bore 24. The enlarged passage 25 has a longitudinal slot 26 and extended outwardly at right angles from said slot the body is provided with respective flanges 27 which function to guide the sliding jaw 13 as will now be described.

The jaw 13 is formed with a substantially semi-circular head 28 of a diameter to slidably fit the enlarged annular passage 25 and has an axially threaded bore 29. It will be noted that the head 28 is located in the medial longitudinal axis of the jaw 13 and upon respective sides of the jaw a channel 30 is formed of such dimensions as to slidably receive a respective flange 27 of the body 11.

The body 11 is formed with a slot 31 at its lower end extending transversely of the bore 24 to receive a nut 32. With the nut 32 positioned in the slot an operating screw 33 is threaded through the nut 32 and also into the threaded bore 29 of the head 28, the jaw 13 being positioned at an upper position of the enlarged annular passage 25. A set screw 34 serves to secure the nut 32 to the operating screw 33 to maintain the latter in operative position.

The operating screw 33 is provided with an angnlarly shaped socket 35, one face of which is provided with a recess 36 for reception of a spring-urged ball 37 fitted in the end 37' of an operating handle 38 when inserted in the socket 35. The handle 38 is also provided with angular studs 39 and 40 adapted to be engaged in angular openings 41, 42 and 43 formed in the body 11, jaw 12 and jaw 13 respectively. The stud 40 is positioned at 45 degrees to the stud 39 which will enable engagement of the handle 38 in the openings 41, 42 and 43 in the event that the cutter cannot be rotated sufiiciently to employ the stud 39.

In use, the cutter is presented upon a pipe to be cut with the cutters 18 and 21 engaging the circumference of the pipe. The end 37' of the Wrench is then inserted within the socket 35 of the operating screw 33. By rotating the screw 38 in the proper direction, the screw 33 will draw the jaw 13 downwardly in the direction of the jaw 12. Thus, the cutting disks 18 and 21 are brought into firm cutting engagement with the pipe and by rotating the cutter by means of the handle 38, the cut will be made. The handle 38 may again be rotated to advance the jaw 13 and the cutter disk 21 toward the jaw 12 and cutter disks 18. In the event that the cutting operation is being performed in a congested area, as indicated in Figures 8 and 9, the handle 38 may be removed from the socket 35 and one of the studs 39 and 40 may be positioned in an accessible opening 41, 42 or 43 as the case may be, whereby further rotation of the cutter 10 circumferentially of the pipe may be effected.

The pipe cutter 10 with the handle 38 engaged in the socket 35 as in Figure 10 provides a fast production cutter, since the cutter may be rotated circumferentially of a pipe and also advance the cutter of the jaw 13 into the pipe.

While I have shown and described a preferred form of the device, this is by way of illustration only, and I consider as my own, all such modifications in construction as fairly fall within the scope of the appended claim.

3 I claim: g A pipe cutter comprising a body having a rigid cutter mount extended outwardly therefrom and having a longitudinal slot formed therein, a pair of cutter disks rotatably mounted in said slot, said body having a bore formed therein extending at right angles to said slot and cutter disks, said bore having a concentric enlarged passage, a cutter mount havinga head slidably engaged in said enlarged passage, said cutter mount having a cutting disk arranged in opposed relation to the cutting disks of the rigid cutter mount, the'head of said cutter mount having a threaded bore, a screw rotatably supported in the bore of said body and threadedly engaged in the bore of the head of said slidable cutter mount, said screw having a socket for reception of a wrench for rotating said screw, and said body, rigid jaw and said slidable jaw are each provided with an angular opening for reception of an angular stud of a wrench.
