SPECIFICATION forming part of Letters Patent No. 282,435, dated July 31, 1883.
lApplication filed January 30, 1883. (No model.)
'o all whom, it may concern,.-
Be it known that I, ELBRIDGE F. BARNEs, a citizen of the United States,-re`siding at New' Haven, iirthev county of New Haven and State of -`Connecticut, have invented certain new and` useful Improvements in Pipe-Cutters, of which the following is a specification, reference being had therein to the accompanyingdrawings.
This invention consists in` certain improve- Io ments in pipe-cutters, as will be hereinafter described and claimed.
In 'the drawings, Figure 1 represents a side elevation, partly broken away, of a pipe-cutter Constructed according to my-invention. Fig. 2 is a top plan view thereof. Fig. 3 is a horizontal section taken on the line 2 2 0I Fig. l, and Fig. 4 is a detail sectional view of a part of the device.
This invention relates to that class of pipe- Qo cutters wherein rotating disks or wheels are pivotally mounted in a framing or support for the purpose of cutting` pipes by the rotation around the saine of such cutter-carrying frame or holder.
A represents the frame, which, according to my improvements, instead of being wrought into the form desired, is constructed of cast or malleable .iron or steel7 with concaved or hollowed-out sides a, cored-out slot or opening,
3o b, and cored-out screw-threaded socket, c. By
thus constructing theV frame A, while the strength thereof is not detracted from, a saving of metal is secured, less labor is required in constructing the same, as the comparatively costly process of `swaging necessary where the tool is forged is dispensed with, and the tool is lighter, and consequently easier to handle.
I construct my pipe or rod cutter with three rotating cutting disks or wheels, B G D, two
.4o (B C) being pivotally mounted, in a manner to be presently described, within the slot or opening b within the curved head A of the frame A, and the other, D, `within a slot or opening, d, in a slide, E. By this arrangement, where it is desired to sever or cut a pipe or rod, the curved head A is placed across said pipe or rod, and the tool turned partly around and back and forth, (insteadof entirely around such pipe,) whereby the cutters will` operate 5o upon-opposite portions of said pipe at the Y same moment, and thus sever the same more quickly and with a less expenditure of force r and labor than is the case where the cutter has to be revolved entirely around the pipe.
ployed in many instances and locations where a cutter that must necessarily be revolved entirely or nearly entirely around the pipe could I not be effectively employed.
E represents a slide, which iscast in steel or iron, with arecess or slot, e, to receive the frame A, upon which said slide slides, and another recess or slot, d, as before mentioned, within which the cutter D is pivoted, and at its lower end with an orice, within which the upper end of the handle F-is received. upper end of this handle F is connected with the lower portionpf this slide in the following manner A recess or groove, e', is formed in the upper part of the handle, and a screw, f, passed through said slide, with its inner end in engagement with said recess or groove.
The 4 In t order to adjust the extent of opening between either to the right or left hand. As it is turned to the right it will push said slide upward, and thus decrease the size of the opening, and on turning the handle in the reverse .direction said handle, as it passes downward, will draw with it the thereto attached slide, and thereby increase the size of the opening. When the desired position has been attained by the slide E, the screw f is tightened within the groove e', and said clamp is held rigid; On' loosening the screw f the slide E can readily be slid vertically upon the frame A whenever desired.
Hcretofore it has been customary to con- -struct the bearing-pins upon which the cuttingdisks revolve of the same circumference, and straight throughout their length, and after such pins have been passed through vthe disks and frame to rivet their ends within or to the frame. I construct the bearing-pins g with one IOO end tapering, as shown at h, Fig. 2, their opposite end and their central portion, upon which the cutters revolve, being straight and cylindrical. When the bearing or pivot pins upon which the cutters revolve are of thei same circumference throughout their length it is necessary that such pins shall be formed of comparatively soft metal, in order that their ends may be readily riveted to the frame after being passed through the same and the cutters. Then whenever, as is often the case in use, one end of such pin becomes worn, it becomesloosened in its bearing, thereby destroying its efficiency as a support for the cutter thereon, which will become unsteady and unreliable in operation'. Again, in so rivetingthebearing-pins the riveting invariably upsets the metal, and thus causes the cutter to work hard. Then whenever it is desired to remove the cutter for the purpose of sharpening the edge of the same, or for other purposes, the riveted bearing-pin can be removed only with difficulty and the loss of much time, and after removal such pin cannot be again employed in the same connection as before. By constructing the bearing-pins with one tapering end, as shown in the drawings, I am enabled to overcome all the objections present to the use of soft-metal riveted pins of straight cylindrical form throughout their length, to wit: I can make such pins out of cast or case-hardened metal, by which means their wear-resisting quality will be increased. They can be readily driven in through the frame and cutters, where they will be securely held owing to their wedge action.v They can be readily and quickly removed at any time desired by simply striking the projecting tapering end with a hammer or other article, and can Ibe reused. The pins will not wear in use as will the soft riveted pins. Therefore the cutter will always run evenly.
I am aware that it has been suggested to make the shanks of the teeth of coal-breakers with tapering ends, and that the bearing or pivot pins of plow-colters have been constructed with a tapering portion; but in thelatter in.- stance the tapering portion has not been designed to secure the pins in position, that being done by means of screw-threads formed on the ends and screw-nuts engaging therewith. I do not broadly claim the employment of pivotpins having a tapering end; but, p
Having thus described my invention, what I claim is u A pipe-cutter having a frame provided with one or more cutting-wheels,the slide E, adapted to embrace and slide upon said frame A, and having rotary cutter D pivoted therein, bearing-pins g, each having one' tapering end, 71., and straight cylindrical remaining portion, and a handle, F, having recess or groove e/ and screw f, substantially as and for the purpose set forth. I
In testimony whereof I affix my signature in presence of two witnesses.
