NITED STATES ATE N'l FFICEQ DENNIS BUSIIOR, OF EFFINGHAM, ILLINOIS, ASSIGNOR TO OEPHAS BUSHOR, I
OF SAME PLACE.
FLU Ey-CUTTER.
SPECIFICATION forming part of Letters Patent No. 303,556, dated August 12, 1884.
Application filed November 16, 1883. (No model.)
To all whom it may concern- Be it known that I, DENNIs BUsHoR, of Eflingham, in the county of Effingham and State of Illinois, have invented certain new 5 and useful Improvements in Flue-Gutters; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and
to the figures and letters of reference marked thereon.
My invention relates to that class of tubecutting implements which are especially designed and adapted for cutting off the pro jccting ends of boiler or other lines preparatory to securing the same in the boiler-head or flue-sheet; and it consists, primarily, in the application to the exterior of the tube or flue to be cut of a removable plate, forming a cutting-edge, to act in conjunction with a 1'0- -tary cutter, whereby the walls of the tube are severed by a shear cut, and at one revolution of the cutter-hcad.
In the drawings, Figurel is a longitudinal section, and Fig. 2 an end view, of the device in position to operate upon a flue. Fig. 3 is a side View of the apparatus.
Similar letters of reference in the several figures denote the same parts.
The cutter-head A is provided with a central opening for the reception of the spindle B, and carries at one side, near theperiphery, the cutting-disk 0, one surface of which is plain and the other convex or beveled, as shown. Anti-friction rollers b b are journaled on the side of the head opposite the cutter. The spindle 13, upon which the'cutter-head revolves, passes through the clamping device D, and is provided near its inner end with two cones, c o, and a screw-threaded portion, (1. The clamping device consists of a cylinder or body, D, slotted radially for the reception of clamps e-three ,or more in number. These clamps are held in the slots by the ringseat 7 and screw-ring 9, under which the lugs or reduced ends of clamps project. The inner faces of the clamps are provided with inclines h h, against which the cones or spindles have a hearing. The stationary shearplate E, in connection with which the cuttingdisk operates, is made in the form of a flat bear upon the clamping-pieces and press to suit different diameters of tubes.
ring or annulus slotted radially at one point to permit of its being sprung onto the tube, and to facilitate its removal therefrom. It is of a size adapted to the tube to be cut, and by 55. its thickness serves as a gage to determine the amount of metal left projecting beyond the flue-sheet for beading or fastening in any wellknown manner.
The operation of the device is as follows: The shear-plate E is first placed in position upon the tube and against the flue'sheet H. A cut is made in the end of the tube with a cold-chisel or other suitable device, sufficient to allow the cutter to rest against or in close proximity to. the ring or stationary shea plate. The clamping-head isfinserted in the tube, and is fastened therein by the screwing in of the spindle, which causes the cones to 7O them outward against the walls of the tube. The spindle being thus secured in position, the cutting-head is brought up by the handwheel 2', working on the threaded section of the spindle,until the cutter occupies the notch previously prepared for it in the end of the tube. The parts being new in position, the cutter-head is given one .revolution by means of a wrench, ratchet, or other well-known device, and the tube is completely severed by the conjoint action of the cutting-disk and stationary plate.
The annular cutting-plate may be removed by means of a chisel or other instrument inserted between it and the flue-sheet. The i11- sertion of a pointed instrument or wedge in the slot will facilitate the withdrawal.
Both the revolving cutter-head and the an nular shear-plate are made of different sizes I claim as my invention 1. The annular shear-plate slotted radially to facilitate its application and removal, substantially as described.
2. The device for centering and sustaining the rotary cutting-head, consisting,essentially, of the coned spindle B, threaded as described, slotted cylinder D, threaded for the reception of the spindle B, clamps e, ring-seat f, and screw-ring 9, all combined and arranged su'b- TOO stantially as set forth.
3. In combination with the spindle B,threadspindle upon which the revolving head is [a mounted, provided with means for centering and sustaining the same within the flue to be cut, substantially as described.
