SPOKE DRIVING AND TENONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 319,942, dated June 9, 1885.

I Application filed July 5, 1884. (No model.)

' To all whom it may concern.-

Be it known that I, HARRY WArKrNs, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Spoke Driving, Tenoning, and Trimming Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention consists in anovel organization of a machine designed to drive the spokes into the hub and cut on the end of said spokes the tenon to which the felly is to be attached, and to perform both said operations in an expeditious and accurate manner at a greatlyreduced cost of manual labor, all as hereinafter more fully explained, and specifically set forth in the claims.

In the annexed drawings, Figure l is a perspective view of my invention. Fig. 2 is a horizontal transverse section on line :0 as. Fig.

3 is a vertical transverse section on lineg 1 Fig. 1. Fig. 4 is an enlarged detached view of the hollow auger employed for forming. the 2 tenon on the end of the spoke. Fig. 5 is a detached face view of the holder of the cutter by which the end of the tenon is trimmed; and Fig. 6 is a detail view of the device for arresting the action of the hammer.

Similar letters of reference indicate corresponding parts.

A represents an upright frame supporting the mechanisms of my invention. Said frame consists, mainly, of two horizontal parallel 3 5 beams supported by stout posts and at an elevation equal to the length of the radius of a large wagon-wheel,for the purpose hereinafter presently explained, and from the said horizontal beams rise posts to the requisite height 0 to accommodate the spoke driving hammer and mechanism pertaining thereto. The lower horizontal parallel beams of the frame A are provided at what I consider the front end of the machine with two half or open boxes, ff, 5 which are mounted on top of said beams and firmly secured thereto, said boxes constituting the axial bearings for a rotary hub-support consisting of a mandrel, f, which is inserted in the eye of the hub and then mounted in the boxes], as illustrated in Fig. 1 of the drawings.

H denotes a hammer arranged over the aforesaid hub-support and in proper position to drive into the hub a spoke hell with its tenon over one of the usual mortises ofthe hub, said hammer being of the species designated trip-hammer, having its beam H pivoted between two horizontal parallel capbeams at the top of the frame A. Back of the heel of the hammer-beam H is a cam, D, se- 6:- cured to the shaft 0, to which latter is also affixed a pulley, F, which by a belt, F, receives rotary motion from a pulley, G, on a counter-shaft, G, which latter is driven by a belt connected with a pulley on the drivingshaft N. The rotation of the upper shaft, 0, causes the cam D to depress the heel of the trip-hammer and actuate the same in the usual manner.

In order to adapt the hammer to drive spokes of different lengths, and thus conform to different diameters of wheels to be formed, I make the hammer H adjustable in length by constructing it of interchangeable transversely-divided sections of different lengths detachabl y connected to the ham mer-beam H.

S denotes a spring-arm connected at one end to an oscillatory supportor pivoted plate, 1?, and at the opposite end with the hammerbeam by a rod, r. To the pivoted plate P is So also firmly attached alever, L, the free end of which has extended from it an arm, a, which is adapted to engage with aratchet, b, secured to the side of the frame A. By means of the aforesaid lever the plate P can be tilted and held in different positions to produce greater or less tension of the spring-arm S, which by its connection with the hainmer-beam impels the hammer with greater or less force.

To the frame A at the side of the hammer- 9o beam is pivoted an elbow-lever, c, which has at one end a shoulder, 0, adapted to engage with a lug, c, on the hammer-beam when the same is raised. The opposite end of the elbow-lever is connected by a rod, (1, with a treadle, e, at the base of the frame. By pressing on said treadle the elbow-lever c is held so as to prevent the shoulder c from engaging the lug c", and thus allow unimpeded movement of thehammer. By releasing the treadle 103 e the lever c automatically engages the hammer as it is raised by the cam D. The im- .pulse received from the latter throws the hamarrest the decent of the hammer.

B represents a rotary hollow auger connect ed to the end of an arbor mounted on a slide, E, moving on guides m, which are secured to the frame A, and are arranged to carry the hollow auger rectilineally and radially in relation to the hereinbefore-described wheelhub support f. The arbor of the aforesaid anger receives rotary motion'by a pulley, a, mounted on said arbor and connected by a belt witha pulley, n, on the driving-shaft N, as best seen in Fig. 3 of the drawings. Underneath the slide E is a shaft, p,extended across the frame A and journaled thereon, and on said shaft is a pinion, 1), which meshes in a rack, 0, attached to the slide E. To the outer end of the shaft is attached a lever, t, by means of which the said shaft can be oscillated and caused to transmit a reciprocating motion to the slide E by the medium of the rack o and pinion p. In front of the lever t is a stop, a, which is adjustably secured in position on the frame A, and adapted to be set so as to arrest the action of the lever 15 and thus limit the movement of the slide E. This arrangement controls the approach of the anger B toward the end of the spoke which has previously been driven into the hub by the hammer H, and subsequently swung over and brought in range with the auger. The aforesaid control of the approach of the auger renders the spokes of uniform lengths. By the adjustment of the stop u the reciprocating movement of the anger is regulated to adapt the auger for operating on spokes of (liflerent lengths. The auger B,I provide with a cutter, w, secured to a plate, 11, which is adjustably attached to the rear portion of the auger-bod y and sustains said cutter,in a plane back of the ordinary cutters, 1), which form the tenon of the :poke. The cutter w is extended to the axial center of the auger, and is set a proper distance from the cutter c to cut off and trim the end of the tenon simultaneously with the operation of forming the same. It will thus be observed that by my improved machine I am enabled to drive the spoke into the hub and form and trim the t-enon on said spoke without removing the hub from its support on the machine. A brace, T, attached to the front end of the frame A, and adapted to bear against the edge of the spoke held there by the operator, serves 'to steady the spoke in the process of driving it into the hub. Another brace, g, is secured to the frame A, and is arranged to bear against "one edge of the spoke while being operated on by the hollow auger B. Opposite the brace g is a brace, h, pivoted to the base of the frame and having its upper end formed with a notch or recess, by which it is adapted to engage one of the edges of the spoke and, in conjunction with the brace 9, hold the spoke during the operation of forming the tenon thereon.

The brace h is moved toward and from the spoke by the following instrumentalities: The upper end of the brace his connected with the side of the frame A by toggles 'i i, from which depends a rod, k, connected to a treadle, l, at the base of the machine. A spring, 8, connecting the free end of the treadle with the frame A, yieldingly supports the treadle in a raised position, and the resultant lifting of the rod and toggles t 2' draws the upper end of the brace h away from the edge of the spoke. .As another spoke 'is swung over into position to be tenoned, the operator depresses the treadle l, and thereby causes the brace h to bear against one edge of the spoke, which is sustained by the brace 9 bearing against the opposite side thereof.

Having described my invention, what I claim as new, Patent, is-

1. In combination with the wheel-hub support and trip-hammer, the pivoted plate P, the spring-arm S, fixed to said plate, rod 7', connecting the Vibrating end of the arm S with the hammer-beam, the lever L, fixed to the plate 1?, and provided with the arm a, and the ratchet b, engaging said arm, all combined substantially as described and shown.

2. In combination with the upright frame A, provided at one end with the wheel-support f, and the hammer-beam H, pivoted to the top of said frame, as shown, the hammerhead H, composed of transversely-divided sections detachably connected, whereby the said hammer-head may be distended or contracted to conform to the diameter of the wheel to be formed, substantially as set forth.

3. The combination, with the upright frame and desire to secure by Letters A, of the boxes f, secured to the lower portion of one end of said frame, the trip-hammer H H, pivoted to the top of the frame, the guides m m on the innersides of the lower portion of the frame, the slide E, mounted on said guides, the hollow auger B, journaled on said slide, the pulley n, attached to the mandrel of the auger, the rack 0 on the slide, a shaft extended across the frame, a pinion on said shaft engaging the rack, the lever t, attached to the same shaft, the stop a, secured adj ustably in its position on the frame and adapted to arrest the movement of the lever t, and mechanism for transmitting motion to the trip-hammer and hollow-auger pulley, substantially as described and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 25th day of April, 1884.
