MOSES O. BUFFINGTON, OF BURLINGTON, IOWA, ASSIGNOR OF ONE-HALF HIS RIGHT TO JAMES M. FORNEY, OF SAME PLACE.

IMPROVEMENT IN WHEELWRIGHTS NIACHINES.

Specification forming part of Letters Patent No. 149,986, dated April 2l, 1874; application filed February 9, 1874.

Cnsn B.

To all whom fit may concern:

Be it known that I, Mosns C. BUFFING- TON, of Burlington, county of Des Moines and State of Iowa, have invented certain new and useful Improvements in W heelwrights7 Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing forming a part of this specification, in which- .Figure l is a top plan or view of my invention. Fig. 2 is a side elevation of Fig. 1, seen from the rear side. Fig. 3 is a vert-ical sectional view of Fig. l on the line x m, seen from the front side and Fig. 4 is a vertical sectional view of Fig. 1 on the line y y, seen from the left-hand side.

The nat-ure of my invention relates to improvements in wheelwrights machines, for sawing the ends of spokes of uniform length, and forming the round tenons thereon, and the invention consists in the arrangement of a table with a shaft driven by power, and carrying a combined hollow auger and (lished saw, said table being provided with suitable devices for holding and adjusting the wheel to be operated upon to the operations of the s'aw and of the hollow auger, all as hereinaf ter fully described.

Referring to the parts by letters, letter A represents any combined circular saw and a hollow auger or tool for cutting round tenons, supported or carried on a shaft, A', the end only of which is shown, together with the adjacent parts of aframe, A, for supporting the same, and the devices constitutin gmy invention, also. B represents a frame with side pieces B B', which slide in grooves formed by the ledges O C on the side of the main frame A, and C is an adjustingscrew, by means of which the height of the frame B may be adjusted on the frame A. D D are horizontal arms of the frame B,connected by an arm,- D', and having' on their upper surfaces slides or ways d d, at right angles from the frameA. E is a rectangular frame, which is notched onto the slides d al. e e are projections from the lower side of the vfralne E, a-nd have eyes or holes, through which spring-retainers e e pass, the one' end of which rests against one side of the frame E, and their other ends againstthe opposite side of the frame B, which conta-ins cavities for their reception. The bars e c are encircled by spiral springs e e between the eye-plates e e and the side of the frame B adjacent to the main frame A. G is a barsecured to the upper Yside of the frame E, with one end projecting ing-lever, pivoted at one end to 011e side of the block J. L is a supporting-rod, bent as shown at Fig. 3, and having one end fixed in the stay-bar 1'., and its other end to the block J. m is a pin projecting from the side ofthe frame E through a hole in the side of the frame A. a is an adjustable stop, threaded where it passes through the frame A. P is a stoppin projecting downward from the frame E. Ris a treadle, from which a strap, 1, passes` upward and. through a suitable hole in the frame A, and connects with the frame E.

The operation of my invention is as follows: The frame B being adjusted to theproper height, the table E is placed thereon, with the pin m projecting through the side frame of A, to stay and aid in holding the table E. The wheel to be operated upon may now be mounted in the chuck h', as shown in the drawings. The set-screw h being loose, the collar H may be adjusted on the bar G to suit the length of spoke required, and iiXed in position by the set-screw h, and the screw h be utilized to adjust the height of the wheel at the hub to suit the different dishing, dsc., when, by means of the nut h', the screw h may be locked in position. The stop a may now be adjusted to limit the sliding movement of the table E toward the auger and saw A, the movement in the opposite or return direction being linnited by the stop P. The wheel may now be turned so as to bring one of the spokes to the action of the saw, as shown at Fig. l, and when sawed o the wheel may be turned a little farther, until the same spoke is opposite to the opening in the hollow au ger, when the calnlever K may be turned down, as shown at Fig. 3, to secure it firmly, while, by means of the treadle R and strap i, the table E may be moved, and the spoke brought to the action of the auger for cutting the round tenon thereon. Upon releasing the treadle R the springs c e will return the table E to its normal position, stopped by the pin P striking the rear side of the frame B, and so 011 consecutively the spokes may be brought to the action of the saw and auger, the bar L (see Fig. 2) `acting as a support while the saw is operating upon the spoke.

It will be seen that by lifting the outer end ot'` the frame E it may be removed from the frame B.

The construction and relative arrangement of the saw and hollowr auger A `are fully described in another application for Letters Pat` ent made by me, and filed concurrently with this. l

I am aware that machines having moving tools and stationary tables have before been used for like purposes; but I am not aware that anyT machine operating like mine has before been known or used.

I claiml. The frame E and springs e e, supported as herein stated, and arranged to operate with the au ger and saw A, clutch h', and clamp K, substantially as described, and for the purpose specified.

2. The clutch hf, adjustably mounted on the slotted bar G, as `set forth, and arranged to operate with the reciprocating table E, stationary table B, and auger and saw A, sub-` stantially as described, and for the purpose specified. t

3. The stops n and P, arranged to operate with the tables ,E and B, and auger and saw A, substantially as described, and for the pur pose specified.

`MOSES C. BUFFINGTON.
