IMPROVEMENT IN BORINCi-MACHINES.
Specification forming part of Letters Patent No. 130,193, dated August 6, 1872.
Specification describing a new and useful Improvement in Boring-Machines, invented by EDWARD OLOOLE, of Pawling, in the county of Dutchess and State of New York.
In the accompanying drawing, Figure l is a side view of my improved machine, parts being broken away to show the construction. Fig. 2 is a top view of the same. Fig. 3 is a detail sectionalview of the same taken through the line w, Fig. 2. Fig. 4 is a detail view of the nut. Fig. 5 is an under-side view of the shell.
Similar letters of reference indicate correspondin g parts.
My invention has for its object to furnish an improved machine for boring'the hubs of carriage-wheels which shall be simple in construction, convenient in use, and effective in operation, being so constructed as to bore the hub perfectly true with .the rim, and to allow the wheel to be put on and taken olf without removing any part of the machine except the rod; and it consists in the construction and combination of various parts of the machine, as hereinafter more fully described.
A are the bed-pieces or bars, three of which ar'e used, and the inner parts of which are curved downward and inward to their point of meeting, where they form equal angles with eachother. Each ofthe bed-pieces Ais formed with a foot or leg, B, of such a length as to raise the machine to a convenient height. The bedpieces A, a little below the point where they begin to curve, are connected by a circularbar, O, and the middle ofthe horizontal parts of the bed-pieces A are connected by straight bars D, which are tangential to the circular bars O, as shown in Fig. 2. The frame A B C D may be cast in one piece, or may be cast in parts and bolted together. The ends of the inner curved parts of the bed-pieces A, at their points of intersection, are faced to receive the circular disks or plates E F, which are placed above and below said ends and are secured in place by bolts. The plate E has a hole in'its center to receive and fit upon the end of the rod that carries the cutter, and the plate F has alarger hole through its center for the passage of the said rod. The holes through the ends of the bed-pieces A, through which the clamping screws or bolts pass, are made larger than said bolts, so that the rod that carries the cutter maybe trued or centered by adjusting the said plates E F. To one of the bed-pieces A, just below the point where it begins to curve, is secured an arm, Gr, which curves upward and inward, so that its upper end may be directly over the point of intersection of the curved inner ends of the bed-pieces A, The upper end of the arm Gr is widened into a disk, g', andhas a flange or hub formed upon it, extending above and below said disk, to form a wide bearing for the rod that carries the cutter. H is the rod that carries the cutter I, and which has a screw-thread cut upon its upper part, so that it may be fed down to its work as it is revolved. The screw-thread ofthe rod H should be square, so that there may be a smooth surface to bear upon the inner surface of the hub of the disk g as the said rod moves up and down. In the rod H, a little below the lower end of the screw-thread, is formed a slot to receive the shank of a cutter, I, which is detachably secured in place by a set-screw, and which may be made of any desired and suitable form. In the upper side of the disk g', upon the opposite sides of its hub, are formed radial grooves, in which are placed blocks J, the inner ends of which pass through holes in the hub of said disk and have screw-threads formed upon them to t into the screw-thread of the rod H, and thus serve as a nut for said rod. In the upper sides of the outer ends of the blocks J are formed notches, into which enter cam or eccentric flanges k1, formed upon the under side of the shell K, which is placed upon the upper side of the vdisk g. The shell K is provided with a short handle, k2, by which it is operated. By this construction, as the shell K is turned in one direction the blocks J are forced inward to take hold of the screw-thread of the rod H, and as the shell K is turned in the other direction the blocks J are drawn outward, so that the rod H may be moved up and down freely. The shell K is secured in place upon the disk g by a collar, L, which is secured to the upper end of the hub of the disk g by setscrews, as shown in Figs. 1 and M is a nut, made in two parts, which are hinged to each other at one end, and secured t0 each other at the other end by a clampingscrew, so that the said nut can be conveniently and quickly moved up and down to adapt it to serve as a stop to limit the downward movement of the rod H. To the upper end of the rod H is attached a crank, N, or other device, by which power is applied to it. Upon each of the bed-pieces A is placed a sliding bracket, O, which is provided with a hand-screw, P, to adapt it to serve as a clamp for securing the rim of the wheel to be bored.
In using the machine the wheel is laid face downward upon the bed-pieces A, the arm G passing up between the spokes to prevent the wheel from turning. Therod H is then inserted and passed down through the hub, through a convenient wooden block placed upon the plate E, and through the plates E F. The conical wooden block is then moved up upon the rod H to enter the lower end of the hub, and thus true or center the wheel from the rod H. The
. ent- The rod H and arm G, in combination with the frame composed of the parts A B C D, constructed and arranged substantially as shown and described,for the purpose specified.
