IMPROVEMENT IN MACHINES FLOR TENONENG SPOKES.

Specification forming part of Letters Patent No. 57,736, dated September 4, 1866.

To all whom it may concern:

Be it known that I, JAMEs LEFEBER, of Cambridge City, Wayne county, and State of Indiana, have invented a new and useful Improvementin Machines for Boring and Tenonlng; and I do hereby declare that the followingis a full, clear, and exact description thereof, vwhich will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a longitudinal section of the frame of my machine in vertical planes on the bent line m in Fig. 3.

This invention consists in a combined boring and tenoning machine, adapted especially for the manufacture of wheels of carriages and other vehicles. It is also calculated for finishing or completing the Wheel thereon, so that it need not be removed until it is finished. The fellies can he doweled thereon by placing a dowelingtable on the machine,

A designates the frame of the machine. A supplementary frame, B, hinged to its side, as seen in Figs. 2 and 3, carries a pulley, C, Whose object is to carry the usual sand-belt for polishing and dressing' the Work. When the said belt (which is not shown in this applica tion) is not being used, the frame B is swung around against the main frame, and when it is in use it is brought out at right angles with the main frame, so that a belt from its pulley C may be run over a pulley on a mandrel or shaft, which may occupy the place ofthe mandrel O, Fig. l.

The right-hand end of the main frame is open on top, and its sides form Ways which support the sliding carriage D that carries the Wheel to be made. The hub of the Wheel is locked to the carriage D by means of an angle-iron Whose upper part goes through the hub and is secured by a nut and washer. The hubis also clamped by a sliding block, E, which is fitted to move lengthwise of the carriage D, and which can be secured by. a set-screw.

The block E serves to hold the hub firmly against the cross-piece Ir of the carriage and, by being movable, allows hubs of different sizes to be secured on the carriage.

The spokes of the Wheel, when tenons are being formed on their ends, and When they are being sawed to the right length, lie on a rest, F, which is made adjustable in height, as seen in Fig. 4, being held by a set-screw in or against the front end of the carriage.

The transverse lever G is pivoted at Z on one side at the front ofthe carriage in line with the rest, being adjustable in height, as seen in Fig. 4. This lever extends across the carriage and is brought down upon the spoke above the rest F, both the lever and the rest having indentations made in them, which receive the upper and lower sides of the spoke, and being thereby enabled to hold it firmly. WVhen the lever is brought down on the spoke the hold-fast b is turned over it and held there until the tenon is made.

The carriage D is brought up to the hollow anger by means of a cog on a transverse shaft, J, which extends beneath the carriage, and whose ends are sustained in the sides of the frame A, one of its ends having a doublegrooved pulley, H, fixed on it. The cog of the shaft engages the teeth of a ratchet, I, made on the under side of thev carriage, and by means of the revolution of the shaft causes the carriage to advance or recede on the frame, the revolution of the shaft in one direction being effected by the treadle K, a cord or chain from Which goes round the pulley H, and in the other, in order to restore the shaft to its previous position, by aweight, L, a cord from which also goes around the pulley, but in the contrary direction to that from the treadle. l

The sanT for cutting off the spokes to a proper length, and the chuck for holding the hollow auger, are supported and operated in the left-hand end of the frame A in a movable frame, P, Which is moved vertically to suit the work by means of a screw, K, in the top .of the stationary frame S, working through the plate or nut Q in the top of the movable frame P.

The stationary frame S stands on a platform, S', which is fastened to the main frame by a setscrew, Y, on one side, and on the other side by a screw-bolt, X, which passes up from the main frame through a slot, NV, in the platform S', and receives a nut, s.

It will be observed from this construction that the platform S can be swung on the main frame around the set-screw Y, as a pivot, and that its fra-me S and the movable frame P, which the latter carries, can thereby be setin an gularf'pdirections with regard to the main frame.

The frame S and platform S can be removed from the main frame at pleasure and another frame fastened in its place.

The movable frame P is so made as to enable the workjof sawing and tenoning to be done by hand, a crank-wheel, U, and shaft T being placed on it, such crank-wheel having cogs on its inner circumference, which engage a gear-wheel, V, formed on the end of a shaft, O, which is also carried in the frame P. The shaft O extends toward the right beyond the end of frame P, and carries a circular saw, N, and also a chuck, M, which receives a hollow auger for making the tenons on the spokes.

1n order to use the saw after the tenons are formed, the frame P is raised by means of the screw K, so as to bring the anger-chuck M high enough to allow the spokes that are to be sawed olf to pass beneath it, when the carriage D is moved forward and the spokes are brought before the saw N.

The extent of motion `allowed to the carriage is governed by a sliding stop, a, that slides on a rod set in a recess in one of the inner sides of the frame A, and which is so set as to arrest the forward lnotion of the carriage at any desired point. When the carriage is brought forward in order to saw off the ends of the'spokes, the stop ais moved forward on its rod as far as it will go, so as to let the carriage move the right distance to bring the spoke opposite the saw. The nut s is then turned loose and the platform S is swung on its pivot Y toward the right, (observing Fig. 3,) so as to bring the saw N to a diagonal position, where its front edge will be nearer the center of the hub than the center of the saw will be, whence it will result that the end of the spoke will be cnt oif at an angle and will be able, when the wheel is turned on its carriagc,

to pass the side of the saw and enable the operator to bring a fresh spoke against the saw. After the spokes are cut off to the proper length the carriage D is run back and the frame Pis lowered until the augerchuck is brought in the same plane with the center or axis of the spoke which is before it. The stop a is then moved to suit the length of the tenon to be made on the spokes, and the front of the carriage D is brought up to the stop, so that all the spokes may have tenons of the same length. When the spokes have all received their tenons the carriage D is run still farther back to enable the operator to place the felly-carriage c on the ways of frameA in front of wheel-carriage D. This felly-carriage is shown in Fig. 7, both in plan and in crosssection. It is curved and rabbeted to enable it to receive a felly and hold it while being mortised to receive the spokes.

The frame J (shown' in Fig. 5) is Yprovided with a pulley, so that power from a belt can be applied to drive the shaft m, which shaft carries two saws, n a, at opposite ends of the frame, and also arotary planer, p, working through a platform provided with a curved guide, g, suitable for guiding the fellies when they are planed or dressed. This frame J can be placed over the stationary frame S by first taking off the hand-power frame Pin order to which the screw K is first withdrawn; then the nut Q is removed from the top bars of frame P, when the latter frame can be lifted off the frame S and set aside, and the powerframe J put in its place. The frames P and J have double sides, so as to inclose the frame S when they are applied to the machine.

When it is desired to use a sand-belt, the supplementary frame B is swung out to the position seen in Figs. 2 and 3, and (the frame P being then on the machine) a pulley (not shown) is placed on the shaft O in place of the chuck N, and a sand-belt can be placed on pulley C and a pulley substituted in place of the chuck M.

I have also provided a head-block,f, for turning, which may also be applied to the frame A. This head-block is seen in Fig. 6. It has jaws h h on each side, to enable it to take hold.

of and slide on the ways of frame A, and is secured to the frame in any desired position by means of a key, fi, which locks the foot of the head-block beneath the under side of the frame in a manner well known to mechanics. By placing the head-block in the frame and using the hand-power frame that carries the chuck M, I am enabled to do all kinds of drilling commonly done in smith-shops. The headblock is also used in turning, in connection with the chuck, the frame P being raised to the level of the center-pin, g, of the head-block, by means of the screw K.

The saw n, next to the planer p, is for sawing the fellies to the desired thickness. The chuck M holds the saw N firm on its mandrel or shaft, and said chuck is suited to receive all the other chucks and angers which are usually employed in shops for which this machine is intended. the frame P is placed thereon, the workman places his left hand on lever Gr and his left foot on treadle K and the right hand on the crank seen in Fig. 1.

The top or table of the frame of the machine may, if desired, be made adjustable ver-- tically, so that it may be raised or lowered to .suit different kinds of work.
