TO ALL WHOM IT MAY CONCERN:

Be it known that I, C. IV. CORR, of Carlinville, in the county of Macoupin, and State of Illinois, have invented certain neW and useful improvements in Wheel-Making Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making'partof this specification, and to theletters of reference marked thereon, -like letters indicating like parts wherever they occur. n

To enable others skilled in the art to construct and use the invention I will proceed to describe it.

My invention has for its object the combination in one machine of allrthe various tools necessary for'driving the spokes, sawing them o`, and tenoning them ready to receive the felloe, and also to turn the felloe and complete the wheel, without removal from the machine daring all these various operations."

Figure 2 is a top plan view.`

A represents the main frame, which may be made of any suitable form and size. Upon this main frame is secured an upper frame, consisting of the upright posts I3 and cross-bars G, (see tig. 2,) the latter being slotted longitudinally to permit of a lateral adjustment. Between the upright posts B is fitted a vertical frame, Q, the edges of which fit into grooves formed in the edges of B to guide itin its vertical movement', the frame O being adjustable vertically by withdrawinglthe bolts a and inserting them in other holes in O made for that purpose. A shaft, M, is mounted transversely of the main frame A directly under the centre of the upright frame O, (see 5g. 2,) and projects at the front side far enough toreceive the hub A', as shown in iig. 1, the hub being secured on the end of the shaft M by means of a screw-bolt, c, which screws into the end of tlf'e shaft, as represented in dotted lines in iig. 2, the bolt c being capable of such adjustment as to ht hubs of any length. 'Io the side of the vertical frame O is secured, by suitable guides, a driving-bar or hammer, D. 'Ihis hammer is operated by the lever I, which is pivoted at its opposite end to the horizontallyprojecting arm I-I, which is attached rigidly to the vertical frame. O. The lever I is operated by the tappet d, secured to a shaft, e', having a pulley, d', driven by a belt, b', from the main shaft b, as shown in fig. 1. The stroke of the hammer D is regulated by means of a sliding-collar, dx, which is kept drawn back by the toggle-lever e and weight g, attached by a.v cord passing over the pulleyf. A rod, e', is attached, as shown, to the toggle-levers e, and extending down by the side of the frame, terminates in a stirrup, e. The sliding-collar ZX is connected by another rod,f, to a spring, f, secured to the frame A. By pressingon the stirrup e the collar 2X is shoved forward on the lever I, thereby causing the spring f to exert more force on the lever I, and thus cause the hammer to strike a heavier blow. As soon, however, as the rod e is released from the pressure of the foot the weight g drawsA the collar ZX back on the lever, thereby releasing the spring f from its tension and causing the hammer D to descend with less force. By thesemeans the blow of the hammer-D on the spokes h may be regulated as desired. A hinged post, E, is secured to the front of the main frame in proper position to support the outer cui of the hub and hold it firm and solid while the spokes are being driven. The object of hinging this post is to enable it to bc turned down out of the Way when the Wheel is to be removed from the machine after it is' finished. The spoke is supported on its rear side by the piece y, which is made adjustable to suit the angle or dish of the spoke; and it is further supported and held steady, while being driven, by means of the forked tool P, the prongs of which are inserted in the cavities on each side of the spoke L in frame O, and hooked over the pins v. A springcatch, Il', serves to hold the hammer up when notin use. Upon the right-hand end of the main fra-meis mounted a metal frame, J, in which is secured the appara-tus for sawing oil' and tenoning the spokes. rlhis fra-nie J is not bolted fast to the main frame A, but is pivoted by means of two arms H', one on each side, to the shaft M, these arms being provided at their outer end, underneath the frame J, with a vertically-projecting plate, z', having a, rack or teeth on'one edge, into which a pinion, z", gears, as shown in tig. 1, these pinions z" boing mounted 'on a shaft extending transverselyY across the main frame, this shaft being provided at one end with a. crank or hand- Wheel for rotating the pinons 2", and thus raising or lowering the frame J and 'all its attachments as may be desired, and as indicated in red in fig. 1. The object of this adjustment of the sawing and tenoning apparatus is this: it is desirable to have the apparatus so arranged that While one spoke shall stand vertically directly under the hammer D, so that the hammer may be driving it, the saw a shall be directly opposite the end ot' one
