ERNEST W. GOURD, OF QUINOY, MASSACHUSETTS, ASSIGNOR OF TWO-TI-IIRDS TO JOHN R. GOURD AND ERNEST D. GOURD,\OF SAME PLACE.

CUTTINGLOFF Tool..

To @ZZ whom t may concern,.-

Be it known that I, ERNEST W. GOUED, of West Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Cutting-.Off Tools, of which the following is a specification.

This invention has relation to implements designed to cut in two lengths or lines of pipe, shafting, rods, bars, &c.

Y It is the purpose of the invention to provide an improved tool of the kind mentioned which may be adapted to cut'o the stock upon which it operates with a straight cut so as not to waste the material or leave indented, uneven, or otherwise damaged edges or parts, and which may also be constructed so that the cutting device may be made to travel around the stock to be cut in two by means of a hand-operated lever, and so also that the device may be applied to a line of shafting or pipe to cut the same in two without disturbing their bearings, all as I will now proceed to describe in detail and set forth in the appended claim.

Reference is to be had tothe annexed drawings and to the letters marked thereon, form-` ing a part of this specificatiomthe same letters designating the same parts or features, as the case may be, wherever they occur.

In the drawings-Figure lis a front elevation of the invention showing it as applied to a shaft in the operation of cutting off the same. Fig. 2 is an end or front elevation of the same. Fig. 3 is a plan view of the same. Fig. 4 is a vertical central sectional View of Fig. 2. Fig. 5 is a horizontal sectional view of Fig. 2, looking upward. Fig. 6 is a plan view of the stationary' hub clamped upon a shaft. Fig. 7 is a transverse sectional view of Fig. l, taken through the ratchet ring. Fig. 8 is an end View of the means for operating the ratchet, showing the latter by dotted lines.

In the drawings a. designates a hollow hub made in twoA (or it may be more) parts, so as to enable it to be placed around a pipe, bar,

place by suitable means, that herein shown, by way of example, consisting of ears c formed Patent No. 519,183, dated May 1,1894. Serial No. 499,095. (No model.)

tapped into the said ears, clamping them together.

e designates screws tapped through the hub, or it may be enlargements f thereon, their inner ends bearing on the material b to be operated upon, in order to securely clamp the hub on the said material.

g designates a revoluble hub arranged on the stationary hub ot so as to move around 6o thereon, being held in place by a iange h resting against the end or front face of the stationary hub, and a flange or rib of the latter entering a groove formed in the interior of the revoluble hub, or by other suitable means. A ringj is arranged between a flange lo of the revoluble hub, and a ratchetringl secured to said hub, so that the said ring may be revolved around the latter hub independently of the said hub. The revoluble hub, as 7o also the ringj, and ratchet-ring Z are made in two or more parts adapted to be secured together by clamping screws, as shown,arranged and operating substantially as is "the case with reference to the stationary hub to se y 5 cure its parts together, all as will be readily understood without further description. To the ring j there is secured a lever m provided with a pawl nwhich is adapted to engage the ratchet Z, and by that means revolve the hub 8o g on the hub a..

o is a friction clip connected with the stationary hub and adapted to be set against the rear end of the revoluble hub with greater or less force to frictionally hold the latter hub against being drawn back by the ring Z `and pawl n, as the same are moved by the handle m in order to have the pawl take a fresh hold of the ratchet.

p q designate bars forming an integral part 9o of or secured to the face of the rotary hubone upon each half or part, said bars having their inner sides `inwardly inclined, so as to between them form a dovetail groove or guideway in which the tool-carrying frame r is adapted to slide, the said frame having its sides formed to conform to the inner sides of the said bars.

s designates the cutting tool adj ustably secured in the upper part of the frame r by roo means of the set screws t, or by other suitable means, the said tool being so arranged as to engage and cut the stock clamped by the stationary hub, when the said tool is carried around the stock and fed toward the axis of revolution of the revoluble hub.

Various means may be employed for feeding the tool, as described, that herein shown consisting of a screw tt tapped through a lug or projection i; on the sliding frame. The head of the screw is provided with a bearing in a lug or projection w on the said frame in which it may turn, though by which it is prevented from moving longitudinally, whereby, by the turning of the said screw the frame r is moved radially with respect to its axis.

As a means for turning the screw u I have employed a ratchet wheel m on the outer end of the said screw which ratchet wheel is adapted to be engaged, at each revolution of the revoluble hub, by a dog y, on the handle m. The said dog is made adjustable toward and from the ratchet wheel as shown, so that it may turn the latter to the extent of one or more teeth at each engagement thereof, in order to feed the cutter in the stock faster or slower, as may be necessary.

In use the parts of the device may be separated in case the tool is to be clamped upon a pipe or shaft, and cannot readily be slipped overthe ends thereof, and the parts are secured together by the screws described, after which the clamping screws e are turned home against the stock to be cut, thus securely clamping the tool on the material. Then by taking hold of the handle m and vibrating the same the revoluble hub may be turned, operating the cutter with the result of causing it to cut a narrow groove in the stock, with straight clean sides until substantially the center is reached and the stock cut off. By this means any form of stock, round, halfround, or angular, and solid or hollow, may

be readily cut off; and this, too, whether the stock is supported at both ends, so that the tool cannot be slipped on endwise or not.

In case of water or gas pipe in the ground or elsewhere, that cannot be gotten at with ease from below, the invention is particularly useful, since the room required below the stock for the tool is only necessarily sufficient for the revoluble parts of the tool to pass.

Having thus explained the nature of the invention and described away of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is A cutting-off tool comprisingin its construction a split hub, adapted to be rigidly clamped upon the stock to be operated upon, a split revoluble hub, adapted to be moved around the first-mentioned hub, a split revoluble ring, provided with a lever, means for detachably connecting the parts of said split hubs and rings, whereby the same may be operatively connected with the stock without passing the same over the end thereof, a cutter carried by, and a ratchet connected with the revoluble hub, the said cutter being adapted to be fed radially into the stock, a pawl carried by the lever to engage and move the ratchet and revoluble hub, as the said lever is vibrated, and means connected with the lever to actuate the cutter feeding means.

In testimony7 whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 19th day of January, A. D. 1894.

ERNEST W'. GOURD.
