P EX DING, C T G, Q3 N L NG- 0 4- App t on. le M rch 1.8- S r l .1 42 4 To all whom it may concern:

Be it known that I, FREDERICK T. CON- LEY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Pipe Expanding, Cutting, or 'Nurling Tools, of which the following is a specification.

This invention has for its object the provision of a compactly arranged and inexpensive hand tool for use in cutting, milling or expanding the ends of pipes, being particularly designed for use by automobilists or others who may be called upon to. make repairs to marine, steam or gas engines having small pipes in their organi zation. The present device is related to and an improvement upon or addition to the device shown in a patent granted to me Feb. 1 ,1919, No. 1,294,404.

In the accompanying drawings:

Figure 1 is a perspective. view of a, tool embodying my present improvements;

Fig.2 is an end view of the tool with a pipe in transverse section;

Fig. 3 is a detail sectional view of one of the gripping jaws;

Fig. 4 is a longitudinal section through the working parts of the tool;

Fig. 5 is a detail perspective view of the turntable;

Fig. 6 is a perspective view of the pipe cutter and the spring by which the main body members are normally held separated.

Fig. 7 is a detail view of the reamer,

The tool comprising my invention consists primarily of two body members crossed near their working ends and pivotally connected at the point of crossing by a boltv 1. The shorter portions of these body members constitute jaws 2 and 3 while the longer portions thereof constitute handle members 4 and 5, the extremity of one of said handle members being forked, as-

shown at 6, and provided with teeth or serrations 7 on one edge of the fork whereby it may be utilized as a wrench. The free ends of the handle members are connected by a screw or bolt 8 having a wing nut 9 mounted thereon and bearing against the.

outer face of one of the members, prefer: ably the member 4 which is provided with the wrench or forked'portion 6. The opposite end ofthe screw or bolt 8 is pivoted to the, extremity of the handle member'5, and

a conical serrated or corrugated body 10, wh ch const tutes a reamer for lncreaslng the diameter of an opening or the bore of a tube, is secured to said member 5 at. the outer side thereof. The gripping jaw 2- carries a webv 11 which may be secured thereon in any desired manner or formed integral therewith and in the said web is mounted two or more rollers 12 to engage against the side of the pipe upon which the tool is to operate. The gripping jaw 3 is bifurcated and the edges of the members ofsaid jaw are serrated, as shown at 13, so that they will obtain a firmgrip upon the pipe placed between the jaws and hold it against 'lative rotation as will be herein-. after set forth. A spring 14.- is coiled around the, pivot bolt 1 and has its spaced divergent extremities 15 bearing against the inner "faces of the handle members 4t and 5 so that the said members and the gripping jaws are normally held apart or in open relation. When it is desired to cause the jaws to grip a. pipe or tube, the end of the tube or pipe is inserted between the jaws and the nut 9 then rotated about the screw or bolt 8 so as to. swing the ends of the handle members together which will obviously cause the jaws 2 and3. to approach and bind against the pipe or tube so as to firmly hold the same' Mounted to swing upon the pivot bolt 1 is a frame 16 having a handle member 17 and a bearing arm 18, a screw 19 being mounted in the said bearing arm, as shown. This screw is provided with a conical head 20 which is adapted to enter the end of a tube or pipe held by and between the jaws 2 and .3, and as it enters the pipe, to expand the same as more fully set forth in my aforesaid application, K

It will be readily observed, upon reference to Figs. 1 and): of the drawings, that the handle members 4: and 5 are grooved on their inner faces or substantially U shaped in cross section and the upper pore tions of the jaws are bifurcated or slotted so that the members may cross each other and be piv'otally mounted upon the bolt 1. Pivoted upon the bolt 1 and disposed between the members of the jaw 3 is the pipe cutter 21 which is shown as a flat bar ha'ving its arms at opposite sides of its pivot point disposed at an angle to each other. The lower arm 22 is housed within the groove or hollow portion of the handle men ne ifi tiono l tters Pa ent- Patented Mar. 310, 19-20..

her 4 and to the lower end of said arm I' pivotally attach one end of an adjusting screw or threaded rod 23 which extends through an opening provided therefor in the handle member 5 and is equipped at the outer side of said member with a wing nut 24 and at the inner side of said member with a lock nut 25. It will be readily understood that by adjusting the said

nuts

24 and 25 the bolt or threaded rod 23 will be caused to move through the handle member 5 and, consequently, will swing the arm 22 about the pivot bolt 1 so that'the upper member or arm 26 will be caused to move toward or from the inner edge of the jaw 3 or the sur face of a pipe held between the jaws. The upper arm 26 of the lever 21 is provided in one lateral face with a groove 27 in which is fitted a chisel-like cutter or blade 28, the said blade or cutter being secured within the groove by a set screw 29 so that it will effectually resist the thrust put upon it and i will remain in proper position relative to the rod or tube being operated upon.

A circular frame 30 is mounted upon the pivot bolt 1 and is constructed with an annular inwardly projecting flange 31 at its inner side which fits against the inner face of the adjacent portion of the gripping jaw 3. The cylindrical wall of this circular frame is constructed with a slot 32 through which the said member of the jaw 3 is passed so that the frame will move with said jaw and will remain constantly in concentric relation thereto. Near the opposite end of the annular wall of this frame is a groove or recess 33 which receives a turntable 34 and a cap ring 35 whereby the turntable is held in position. The turntable consists of an annulus or flat ring provided with outstanding lugs 36 at diametrically opposite points and having a handle 37 secured to or formed integral with the ring between the said lugs, the said handle, as shown most clearly in Fig. 4, being shaped to extend through the cap ring 35 and then extend radially from the turntable and circular frame so that the required turning movement may be impart ed to the table in the operation of the tool. Flat sided screws 38 are inserted through the lugs 36 and to the inner ends of said screws are pivotally attached the ends of links 39, the inner opposed faces of all the links being serrated, as shown at 40, and the links attached to each bolt diverging from their pivotal connection therewith and having their ends remote from the bolts pivoted to the ends of the links extending from the opposedbolt, as shown at 41. A collapsible vise is thus provided which is adapted to fit around the pipe or tube, indicated at 42 in Fig. 2, and securely clamp the same against all relative turning movement. Winged nuts 43 are mounted upon the bolts 38 and bear against the outer faces of the will be readily understood. If it be desired to expand the end of a tube or pipe, the pipe is gripped between the jaws 2 and'3 and the frame 16 swung about the main pivot or securing bolt 1 so as to bring the conical head 20 into axial alinement with the tube or pipe, after which the screw 19 is rotated in its bearing to cause the said head to enter the end of the pipe and thereby spread or expand the same as previously stated. If it be desired to cut through a pipe so as to sever a section of any given length therefrom, the frame 16 is swung downward out of the way and the pipe is then inserted through the links or jaws 39 and between the gripping jaws 2 and 3 until the required length .of pipe or tube haspassed beyond the cutter 28. The nuts 43 are then manipulated so as to cause the link jaws 39 to firmly clamp the pipe or tube, as shown in Fig. 2, after which the adjusting screw or bolt 23 is caused to move through'the handle member 5 by manipulating the

nuts

24 and 25 and the pipe cutter or lever 21thereby swung about the pivot bolt 1 so that the blade 28 will be caused to bear upon the pipe or tube as shown in Fig. 2. The screw or bolt 8 then may be manipulated so as to bring the jaws 2 and 3 into engagement with the pipe with just enough, force tov steady the movement'of the tool and prevent bending or twisting of the pipe but should not be so manipulated that the jaws 2 and 3 will bind upon. the pipe. The handle 37 is then rotated about the axis of the frame 30so that the turntable 34 with the link jaws 39 mounted thereon will be caused to move in a circular path within said frame, thereby causingthe pipe or tube which is clamped by and between said jaws to rotate about its own longitudinal axis. Inasmuch as the blade 28' is biting into the pipe, a groove will be cut in the surface of the same and the cutter will be adjusted after each complete revolution of the pipe so as to increase the depth of this cut and thereby gradually cut through the entire wall of the pipe so as to sever a section therefrom. After the pipe has been cut entirely through so that the desired section will be severed, the link members 39 are released from the main section of the tube or pipe and the gripping jaws 2 and 3 are also released so that the cut-off section may be removed and fitted where desired. The tool' may be also manipulated accomplish this result, the tube or pipe isinserted through the vise composed of the link jaws 39 in the manner before described with the end of the pipe or tubedisposed between the gripping jaws 2 and 3 andthe cutter adjusted so that it will not come into contact with the pipe. The screw or bolt 8 is then adjusted so as to bring the jaws 2 and 3 into engagement with the pipe or tube so that the serrations 13 of the jaw 3 will bear firmly against the pipe but will not bind or grip into the same. If the turntable be then rotated by means of the handle 37, the pipe will be caused to rotate between the jaws 2 and 3, moving easily upon the roll ers 12, while the serrations 13 of the jaw 3 will scrape or wear upon the surface so as to produce the desired roughening or mill- %rom the foregoing description, taken in connection with-the accompanying drawings, it will be seenthat I have provided a very simple, compact and inexpensive tool which may be carried in an ordinary tool box and which may be efliciently employed for a variety of purposes. The tool is light and easily operated by an unskilled person so that satisfactory repairs may be made in out of the way places and by persons who have no access to fully equipped machine shops or factories.
