Patented May 28, i872.,
UNITED STATES AUSTIN BASGOM, OF SENECA, MICHIGAN.
IMPROVEMENT IN HUB-BORING MACHINES.
Specification forming part of Letters Patent No. 127,296, dated May 28, 1872.
To all whom t may concern:
Be it known that I, AUsTIN BAscoM, of Seneca, in the countyr of Lenawee and State of Michigan, have invented a new and valuable Improvement in Hub-Boring Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.
Figure l of the drawing is a representation of a side view of my invention. Fig. 2 is an end view. Fig. 3 is a plan view. Fig. 4 is a vertical section on line A B, Fig. 2. Figs. 5 and 6 are sectional views through lines D C and E' F', respectively, shown in Fig. 2.
This invention has relation to hub-boring devices; and consists in the construction and novel arrangement of the parts of a machine adapted to the purpose of borin gtaperin g holes through wheel-hubs, as hereinafter described.
Referring to the drawing, A designates a wheel-hub; B, the spokes C, a circular faceplate, securedto the spokes bymeans of clamps d, adjusted by the thumb-screws d. D indicates a cylindrical box, made in two semicircular, coinciding parts, each part provided with laterally-projecting arms or braces E, which are bent down toward the face-plate C and secured to it by bolts or screws c. The arms on each side of the box D are secured together by means of screws or bolts e. Each end of the box D is furnished with a cap, F, which is grooved around its periphery to receive an internal iiange or ridge projecting from the box D at f for the purpose of holding it in place while allowing it a rotary motion. ln said cap is made arectangular aperture or mortise, G, which contains a square or cubical block, g, through which passes the threaded bit-shaft g1; said block having a circular hole cut through its center. On opposite sides of said block notches are made to receive, respectively, the ends of right and left hand screws h, which pass through the cap F and serve to adjust the block to different positions within the mortise G. Along the shaft g1 channels g2 are formed, and entered by the ends of studs g3 projecting from the sides of the hole through the blocks g. By means of said channels and studs the shaft g1 is prevented from turning independently of the caps F, but is allowed to move lengthwise through them. H designates a pair of hinged jaws, constructed with an internally-threaded opening, formed by spreading the jaws at h to the form of a collar and cutting threads to iit the thread on the bit-shaft, which passes between said jaws, these jaws being extended from a key which traverses the box D and projects through slots I, on opposite sides thereof, as shown. The jaws H being hinged together may be spread apart, when desired. They are locked together by means of a link,, hinged to the end of one and adapted to encircle the end of the other. In one end of the shaft g1 is cut transversely a dovetailed gain or channel, in which iits the shank of an adjustable cutter-bit, K.
This machine operates as follows: The faceplate G is secured to the outside of the spokes, concentric with the hub and rim of the wheel, in order that the hole through the hub may be bored true. The box D is then arranged, and the shaft g1 passed through the center of the hub. It is then adjusted by means of the cubes g, the relative positions of which regulate the size and shape to which the hole is to be cut. The work is performed either by attaching a handle to the end of the bit-shaft and turning it,-while the wheel remains stationary, or by securing the end of the shaft in a socket and turning the wheel. In either case the result is the same. When the wheel is turned the box D revolves around the shaft, moving along it, so that the operation of cutting progresses from the inner to the outer end of the hub, or vice versa. The motion of the shaft when turned, or what is equivalent thereto, the motion of the box D, is eccentric.
The tapering form of the hub-box is the result of the gradual lessening of the radius of the eccentric circle passed through by the cutterbit.
The caps F revolve with the shaft, and with the blocks g govern the size of the circle passed through by the cutter-bit, and the extent of its deviation from the true center of the hub.
In order to form a tapering hole through the hub the cubical blocks g must be so arranged that the shaft g1 shall describe a cone in its movement. But these blocks may be so adjuste-d `that the shaft shall describe a cylinder, so that the shoulder for the axle-nut may be cut at the outer end of the hub after the tapering,` spindle-bearing has been formed.
By the opening of the jaws H the shaft g1 may be moved along without cutting, so that after cutting the Spindlebearing through the shaft may be moved back to cut the nutshoul der. t
lhe cutter is in the form of a hook, and cuts with two edges, n, both of which are capable of being sharpened on a grin dstone when dull.
The box D is made in two halves, so that the caps F may be properly tted, and so that whentheir bearings become worn, they may be diminished in size by filing the contiguous edges of the semicircular halves of the box.
Y What I'clailn asmy invention7 and desire to secure by Letters Patent, is
The box D, constructed in two coinciding parts, rotary caps F, adjustable blocks g, and
of two witnesses.
