WHEELWRlGHT-MACHINE.

SPECIFICATION forming part of Letters Patent No. 249,026, dated November 1, 1881.

Application filed August 10, 1881. (No model.)

To all whom tt may concern Be it known that we, WILLIAM H. DOANE and GEORGE W.BUGBEE, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Wheel- Machines 5 and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

In the manufacture of carriage-wheels and other wagon-wheels theouter ends ofthe spokes are cut off to even lengths and tenoned after they have been driven into or, otherwise secured in the hub.

This invention contemplates a wheel-tenoningmachine adapted to first cut off and then tenon the outer ends of the spokes, one after the other, and embodying the combination of a circular saw for cutting off the spoke'to proper length and a concentric tubular cutting-tool for cutting the tenon on the end of the spoke.

Our improvement consists of certain combinations, set forth in the claims at the close of this specification.

Inorder that our invention may be clearly understood,we haveillustrated in the annexed drawings, and will proceed to describe,'a ma chine embodying all the features thereof in the best form known to us at this time. I

Figure 1 is a perspective view ofthe machine complete, showing a spoked hub or wheel in position to be operated on. Fig.2 is an end elevation. Fig. 3 is a side elevation, portion of the swinging frame oryoke on which the mandrel is mounted being broken away. Fig. 4 is a plan view, omitting the wheel-rest and screw carrying it. The counter-shaft and belt-gearing is omitted from Figs; 2, 3, and 4.

The same letters of reference are used to indicate like parts in all the figures.

The main frame A is provided at its forward end with alongitudinally-slotted guideway, A, in which the block-nut B is seated, so that it may be adjusted longitudinally to vary the distance between it and the cutting-toolsat the other end of the main frame. The block nut carries a vertical screw, 0, to the head of which the rest D is swiveled. The screw extends down through the slot of the guideway, and is provided with a hand wheel for operating it. The screw also carries a jam nut below the guideway, by which it may be locked and the block-nut clamped to the guideway at the same time. The spoked hub or wheel to be operated upon is supported on this rest D and firmly clamped by the sliding jaws D.D, fitted on the rest, and operated simultaneously by a right and left adjusting-screw, d. The blocknut B, screw 0, rest D, and jaws D D thus constitute a longitudinally and vertically adjustable wheel-support. After the spoked hub or wheel has been thus fastened it must be adjusted with reference to the centeringclamp composed of the jaws E E and the spoke-rest E all mounted on the arch A of the main frame.

The spoke-rest is fitted in a vertical guideway on the arch, and held in position by a clamping-nut on a screw-bolt supported in the arch and passing through a vertical slot in the spoke-rest. The arch is laterally adjustable on the main frame, in order that the centeringclamp may be nicely adjusted with reference to the tenoning-tool. The jaws E E are pivoted at e e on the arch A and are constructed with segmental series of iutermeshing teeth. The jaw E is constructed with an arm, to which one end of a connecting-rod, F, is pivoted,the other end of which is pivoted to the treadle F, fulcrumed on the main frame and extending to the front side of the machine. By depressing the treadle the jaws may be closed simultaneously.

A counterbalance-weight may be connected to the connecting-rod end of the treadle, for opening the jaws automatically when the operators foot is .taken off of the treadle.

The height of the spoked wheel should be so adjusted that the spokes will just slide over the spoke-rest E and the distance of the hub from. the centering-clamp should be made such that the jaws thereof will grasp the spoke some distance from the shoulder of the tenon.

The circular saw Gis fixed to a tubular head,

vH, on the mandrel H, and suitable cutters are fixed in this head II, forming therewith a tubular tenoning-tool concentric with the circular saw. The mandrel H turns in bearings in a frame or yoke, I, hinged ati i to the main frame along its rear edge, the center of the hinge being so located that at a certain point in the arc of motion of the swinging yoke the axis of the mandrel will be substantially coincident with the center of the end of the spoke held on the spoke-rest and grasped by the centering-clamp. The outer end of the mandrel H is connected by a cross-head to one end of a guide-rod, K, resting in ears 6 on the swinging yoke. The other end of the guide-rod extends to and bears on the side of a fixed segmental guide, L, in the upper end of which a hole, I, is formed, adapted to receive the end of the guide-rod K. The arc of guide L is struck from a point in the axial line of the hinge ofthe swinging yoke, and its hole I is so located that when the guiderod K is coincident with it, then the axis of the mandrel will be coincident with the center of the end of the spoke held on the spoke-rest between the jaws of the centering-clamp.

A laterally-projecting stop, l, maybe formed on the segmental-guide L, to arrest the upward motion of the swinging yoke when the guiderod K is brought opposite the hole lin the guide L. The guide-rod K and guide L govern the movement of the saw acrossthe end of the spoke.

The mandrel H can slide in its bearings and projects a considerable distance through the rear one thereof, so that it may moved to any required extent toward the spoke. Its movement toward the spoke is determined by the position of an adjustable collar, 70, on the guiderod K with reference to the adjacent ear 1" of the swinging yoke. In the lowest position of of the swinging yoke the circular saw will be below the end of the spoke, which is cut off by the saw on raising the swinging yoke. \Vhen the yoke has been raised to its highest position the mandrel H is slid forward in its bearings, so as to cause the tubular tenoningtool to cut the tenon on the spoke, the required length of which is determined by the position of the collar k on the guide-rod K. After the tenon has been cut the mandrel, with its tools,is retracted until its guide-rod is withdrawn from the hole in the segmental guide L, when the swinging frame is again lowered to permit the spoked hub or wheel to be turned for presenting the next spoke. A lever, M, is a convenient means for swinging the swinging yoke as well as for sliding the mandrel, it being pivoted to the guide-rod K and fulcrnmed on the swinging yoke in the manner shown.

The mandrel carries a fastpulley, Hfldriven by a belt, N, from a pulley, N, on an overhead counter-shaft, N. In order to preserve the tautness of the belt, its slack side is passed over an idler -pulley, O, on a shaft, 0, supported in downwardly-projectin g arms on the hangers of the counter shaft; and between the idler O and the driving pulley N a loop is formed in the slack sideof the belt,in which loop a pulley, P, is placed,journaled to a stirrup, P, from which a rod, P is suspended, carrying at its lower end a weight, P In moving the swinging yoke up and down the weight P will move reverselyup and down, so that the driving action of the belt will be preserved in all positions of the swinging yoke, the weight P being made suificiently heavy to that end. The swinging -yoke, with its adjuncts, is also in a measure counterbalanced thereby.

A hook-latch, B, may be thrown over the guide-rod K to hold the swinging yoke down with certainty while the operator is removing a finished spoked hub or wheel and mounting another one.

Having thus described our invention, whatwe claim is- 1. In a wheel-tenoning machine, the combination, substantially as before set forth, of a circular saw, a concentric tubular tenoningtool, the mandrel common to both, and the swinging yoke supporting the mandrel, whereby the saw is first moved across the spoke to cut off its end, and then the tenoning -tool brought into line with the end of the spoke.

2. In a wheel-tenoning machine, the combination, substantially as before set forth, of a circular saw, a concentric tubular tenoningtool, the rotating and endwise movable mandrel, common to both, the swinging yoke supporting the mandrel, and the lever for swinging the yoke as well as moving the mandrel endwise.

3. In a wheel-tenoning machine, the combination, substantially as before set forth, of

the mandrel of the circular saw and concentric tubular tenoning-tool mounted on a swinging yoke, the guide-rod fixed on the mandrel, and the fixed segmental guide for governing the movement of the saw across the end of spoke.

4. In a wheel-tenoning machine, the combination, substantially as before set forth, of

the rotating and endwise movable mandrel of the circular saw, and concentric tubular tenoning-tool mounted on a swinging yoke, the guiderod fixed on the mandrel, and the fixed segmental guide constructed with a hole for governing the movement of the saw across the end of the spoke as well as the endwise movement of the mandrel.
