JORDAN STEWART MAYSE, OF BRADY, TEXAS.

WHEEL-STRAIGHTENING MACHINE.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed June 29, 1905. Serial No. 267,523.

To all whom it may concern.-

Be it known thatI, JORDAN STEWART MAYSE, a citizen of the United States, and a resident of Brady, in the county of McCulloch and State of Texas, have invented a new and Improved Wheel-Straightening Machine,-of which the following is afull, clear, and exact description.

This invention relates to means for straightening light or heavy wagon-wheels when the spokes become loosened and the wheel is excessively dished, and has for its object to provide novel details of construction for a machine of the character indicated which enable the quick and convenient straightening of a light or heavy vehicle-wheel in a perfect manner, for the removal of an excess of dish or concavity from either side of the wheel, and the straightening of vehicle wheels that have either wooden hubs or flanged metal hubs and having either metal or wooden spokes, and facilitate the removal and resetting of the tire on the rim of a wheel that has been straightened on the improved machine if this is necessary.

The invention consists in the novelconstruction and combination of parts,as is hereinafter described, and defined in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a partly-sectional side view of the improved wheel-straightening machine arranged for straightening a vehicle-wheel having a flanged metal hub. Fig. 2 is a partlysectional side view of the machine arranged for straightening a wagon-wheel having a wooden'hub. Fig. 3 is a detached plan view of a frame-ring, a presser-bar thereon, and portions of supporting legs engaging the frame-ring; and Fig. 1 is a transverse sectional view of details of the machine, taken substantially on the line 1 4 in Fig. 1.

In the drawings, 5 indicates a frame-ring, and 6 a plurality of supporting-legs therefor.

The frame-ring 5 is in the form of a metal hoop having proper dimensions for effective service, and, as shown, four legs 6 are employed for the elevation of the ring a suitable distance from the floor or other firm supporting-base. Each of the similar legs 6 is formed of a metal bar bent at a right angle between its ends, as indicated at a in Figs. 1 and 2,

.what below the upper surface ofthe horizontal frame-bars.

Upon each frame-bar 6 a looped bracketarm 7 is mounted, the'spaced limbs thereof loosely embracing the frame-bar and the integral spacing member of said limbs having "contact with the lower edge of the frame-bar, as appears in Fig. 1. Between the upper ter minations of the spaced limbs of each bracketarm 7 a rock-arm is pivoted between its ends, one portion 8 of the rock-arm inclining toward'the loop I) on the frame-bar 6 and having contact at its lower end therewith. The other portion 8 of each rock-arm extends from the pivot c, which is between the middle of the rock-arm and the upright members of a respective bracket-arm 7 above and parallel with a respective frame-bar 6, as is clearly shown at the left in Fig. 1;

Each member 8 of a rock-arm 8 8 terminates at its outer end in an integral nut 0, that is vertically perforated and threaded internally for the reception of a clamping-screw 9, the head of which is adapted for rotation by a suitable lever, the lower end of each screw having a swiveled block 0 thereon which is designed for engagement with the rim of a wagon-wheel, as shown in Figs. 1 and 2 and hereinafter more fully explained.

A carrier-bar 10 is mounted at its ends on the frame-ring 5, preferably as shown in Figs. 1 and 2, the end portions of the bar having hook formations dd thereon, which hook upon the upper edge of the frame-ring, and thus support said carrier-bar horizontally across the center of the frame-ring.

As hereinbefore mentioned, the improvement is well adapted for removing excessive dish or concavity from a vehicle-wheel having a metal hub and washer-like clampingplates mounted on the hub, one at each side of the spokes and clamped thereon by bolts, such a wheel being represented in Fig. 1, A

representing the wheel-rim or felly; B, the spokes; C, the hub, and D D the clampingflanges that are mounted upon the end portions of the hub and respectively are clamped against the spokes by screw bolts or rivets.

In order to adapt the machine to straighten a wheelof the construction specified, and represented in Fig. 1, the machine further consists of a nut plate 11, having a suitable length and a flat body centrally perforated and threaded in said perforation. A pressure-screw 12 of suitable length is provided with a cross-handle 12 or other means for its manual rotation, and the threaded lower portion thereof is screwed through the tapped hole in the center of the nut-plate when the device is in service. A carrier-sleeve 13 is seated upon the nut-plate ll concentric with the pressure-screw 12, said sleeve having sufficient length to engage its upper end with the lowermost hub-plate D, when the wheelrim A is imposed upon the frame members 6*, and thus supported horizontally.

Assuming that the wheel is placed on the frame-bars 6, as shown in Fig. 1, and is firmly secured thereon bya clamping adjustment of the screws 9, the bracket'arms 7 and the rock-arms thereon being located between spokes of the wheel, so that the inclined members 8 of said arms will be forcibly impinged upon the frame-bars 6, this will dispose the hub of the wheel centrally in the frame-ring 5, so that the pressure-screw 12 may be passed down through the hub and then screwed a suitable distance down through the nut-plate 11 into contact with the carrier-bar 10. It will be noted that the pressure of the screw 12 on the carrier-bar 10 will by means of the carrier-sleeve 13 be transmitted to the lowermost disk or plate D, and through said plate raise the hub C sufficiently to remove an 0bjectionable degree of dish had previously by the wheel. The straightening of the wheel having been effected by means of the machine as described, this readjustment of the spokes of the wheel will produce gaps between the hub and spokes in the mortises occupied by the tenons on the spokes, and to prevent the latter from moving in the mortises, soas to again become improperly dished, the gaps mentioned may be filled with molten lead or other soft metal, thereby securing the spokes solidly in the hub, the operation then being completed by clamping the plates D against the spokes C. i As shown in Fig. 2, the improved wheelstraightening machine may be advantageously used for straightening wagon-wheels or, in other words, for removing excessive dish therefrom if the wheels are manufactured completely of hard wood, with the exception of the tire. To this end the nut-plate 11 is provided with two screw-holes, one near each end of the same, and two pressure-screws l2 are employed, which in service-are screwed 5 down through these threaded perforations in the nut-plate and into enforced engagement with the carrier-bar 10, the lowermost band on the hub seating upon the nut-plate.

It will be seen that when the'wagon-wheel A is imposed upon the frame members 6*and clamped thereon by the screws 9 the machine will be adapted for the removal of excessive dish in the wheel by screwing the pressurescrews 12 through the nut-plate 11 and thence into contact with the carrier-bar 10", said screws causing the hub of the wheel to rise from the carrier-bar 10 It is to be understood that in any case where the'spoke-tenons have become loosened after a correct dish has been given to the spoke this dish may be rendered permanent by filling the crevices between the spoke-tenons and the hub with molten metal or other available material.

The improvement is also adapted for use as a means for supporting vehicle-wheels when tires are to be shrunken thereon. To this end the wheel may be held in place by means of the central clamping device and' the rimclamping means be displaced, so that the pe ripheral surface of the wheel-rim is fully exposed, and thus adapted for receiving a hot tire, which may be conveniently placed in position, as the wheel is supported at a convenient height from the ground or floor whereon the machine stands.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A wheel-straightening machine,embody ing a frame having depending legs, a horizontalcarrier-bar on the frame, means carried by the frame for clamping a wagon-wheel thereon, a nut-plate, a sleeve extending between a flange on the wagon-wheel and the nutplate, and a pressure-screw working through {)he nut-plate and bearing upon the carrier- 2.
