Specification of Letters Patent.
Patented N 0V. 16, 1915.
Application led November 22, 1912, Serial No. 732,858. Renewed September 18, 1915. Serial No. 51,408.
To all whom z'tmay concern:
Be it known that I, JOHN R. LONG, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Means for Reaming and Threading Pipes, of which the following is a specication.
'This invention appertains to means for roaming and threading pipes, and the invention consists in the novel 'construction and arrangementof parts whereby a cutting tool may be mounted for end movement in respect to the pipe by a device adapted to engage within the pipe all substantially as shown and described and particularly pointed out in the claims.
In the accompanyingdrawings, Figure 1 is a side elevation of a reamer and anchor combined, and Fig. 2 is a-longitudinal section of aV pipe with my anchor engaged therein. Fig. 3 is a similar view of the anchor alone in a smaller pipe than shown in Fig. 2, and Fig. 4 is a similar v iew of a larger pipe and the anchor therein but with the jaws in a diiferent position in the spreading head from that shown in the preceding views and as hereinafter described. Fig. 5 isa front perspective view of the jaw carrying head, and Figs. 6 and 7 are sectional elevations thereof on different lines. Fig. 8 is a perspective view of one of the two jaws. Figs. 9 and 10 are side elevations of the reaming or cutting tool from different points of view, and Fig. 11 is an end View showing the smaller end of the tool. Fig. 12 is a sectional side view and elevation of a modiication of the invention.
As thus shown the plan of the invention is to anchor the reamer or reaming tool or other cutter 1n or on the pipe to be reamed,
and the anchor is adapted to work in pipes of various sizes, from the minimum 1n Fig. 3, tothe maximum in Fig. 4. Thus in Figs. 1 to 11 I show a device consisting in a tube 2 which has an external thread 3 at its outer end and carries the `jaw adjusting or spreading head 4 on its inner end. The reaming tool 5 will be seen to be original and peculiar in shape in this particular, that it is an open member which by reason of its construction as shown, can be drop-forged and thus made comparatively cheap from a manufacturing point of view and yet serve all the purposes 0f a reamer for a plumber who takes the tool out on a job and really does not require as elaborate or expensive a tool as is usually provided for factory work. Hence I have made the present tool which has opposite cuttmg blades or ribs m conically disposed as. in such cuttersusually and united at or within the point by a collar shaped integral cpnnection n and provided with a head or base portlon o having an internal thread by means of which the said tool is mounted upon its support 6. Otherwise the mechanism shown has to do with feeding said head and tool forward under spring pressure as roaming proceeds, and comprises a follower 8 with a wheel or handle to rotate the Asame and bearing against a suitably heavy spiral spring 7 in the hub of head 6 and which presses against the said reamer to feed the same along under. spring pressure while it is being rotated through head6.
The anchoring' means comprises a head 4 as described which is mounted or socketed on the end of tube 2, and an adjusting rod or tube 10 passes lengthwise through said tube 2 and has a collar 12 within the annularly enlarged end thereof bearing against said head 4 While the inner extremity a of said rod is threaded and carries the adjusting nut 14 which `supports the jaws l5. The said nut is threaded to be run back and forth on the thread a according to the size of the pipe in which it is located for the time and the spread the jaws are to receive therein, and said jaws are pivotally .mounted between the ears Z1 on the said nut and adapted to work in the transverse slots or recesses c and 0l respectively in the said head 4. For pipes of the smaller or medium sizes the said jaws are engaged in the inclined slots 15, and for larger sizes, as Fig. 4, they are engaged in the recesses or slots d in which the right angled shoulders or walls g take the place of said inclines 7 and throw the jaws outat a more direct angle, as seen in Fig. 4. The said jaws are supported on pivot 'pins in said recesses and have springs s to press them inward,normally, and are provided withy -teeth 7L at their outer ends arranged more or less in a circle so as to make biting engagement with the interior wall of the pipe in any position of adjustment. A dowel pin 20 or its equivalent serves to limit the open ory outerposition of the nut 14 and beyond which it need not be moved to accommodate itself and jaws 15 to the smallest .Thus it will be seen that the follower 8 runs on sleeve 2 and serves through the intervening spring to press the reamer forward under spring pressure, while the rotatable head 6 which has the reamer fixed thereon serves to actuate the same and do the reaming. Of course in. the use of the reamer the first step is to get itanchored in the right position in the pipe. This being done by effectively engaging the jaws 15 in the pipe P preparatory to setting-the other parts, the follower 8 is next turned to v press the cutter or reamer 5 to cutting position. In this operation the said reamer is placed under spring pressure as above described. Then the parts are in readiness to begin the reaming and the said spring keeps the reamer at work under the requisite pres-v sure as ,the workproceeds. Vhen done the jaws 15 are released and the entire device is withdrawn.
My inventive concept also includes the arrangement and construction of parts shown in Fig. 12, whereby a die stock of common form may be substituted for the reamer shown in the other figures. In the larger sizes of pipe it is exceedingly diiicult to start threading operations and also to complete such operations, but with the aid of my improved device, such operations are more easily and eiiiciently accomplished. Thus, as
shown, a die stock 25 is mounted upon the -end of a piece of pipe P in a starting position to provide the same with an exterior thread.l The die stock'is held/in this position under more'or less pressure applied by the follower 8 threaded on sleeve. 2 of the anchoring device, a loose bearing washer 26being interposed between the die stock and said follower and ',adapted to press the said stock forward into threading posi? tion. The edges of the cutting jaws of said stock are beveled to make. the ascent easy, and when the 1'n1tial or lead thread has been cut the said stock will feed itself and all the other portions of the device are removed and the stock is left to complete its work in the usual way.
jaws pivoted on said nut and free at their? outer ends, in combination with a tapered head adapted to spread said jaws having recesses in which said jaws are slidable to spread into engaging position, a tube sleeved over said rod and having said head fixed on its outer end, and means-to turn saidrod independently of said tube and thus 4feed said nut and spread the jaws.
2. In devices for securing cuttingtools in working position on a pipe, an anchor comprising a head having recesses axially mounted, a rod extending through said tube and head having a threaded end, a -nut mounted on said threadedend and a setof anchoring jaws 'pivoted on said nut and resting in said recesses, the said rod having a collar fixed thereon within said head to prevent axial movement ofthe rod when rotated, and springs in said head bearing on said jaws to `press the same inward.
inclined and a tube on which said head'is 3. A device for fixing cutting tools in Lpipes comprising a tube and a head fixed on one end thereof having radially disposed recesses inclined to the axis of said tube, in combination with a rod through said tube and head having a threaded end, a nut mounted on said threaded endv and pipe engaging jaws pivoted thereon and resting in said recesses, means to rotate said rod and thus thrust said jaws into engaging and dis, engaging positions, a pipe reamer having inclined cutting ribs rotatably mounted on said tube, means to rotate said reamer and a spring in the reamer to feed the same along when at work. v
In testimony whereof I aiix my signature in presence of two witnesses.
