OLIVER J. DOERTY, OF FINDLEY, OHIO, ASSIGNOB OF ONE-HALF HIS RIGHT TO JOHN H. JOHNSTON, OF SAME PLACE.
IMPROVEMENT IN WHEELWRlGHT-MACHINES.
Specification forming part of Letters Patent No. 152,348, dated June 23, 1874 5 application led May 16, 1874.
To all whom fit may concern:
Be it known that I, OLIVER J. DoERrv, of Findley, in the county of Hancock and State of Ohio, have invented Ya new and valuable Improvement in Wheelwright-llachines5 and I do hereby declare that the following isa full', clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.
Figure l of the drawing is a represent-ation of a longitudinal section of my machine. Fig. 2 is a cross-section, and Fig. 3 is a plan view; and Fig. 4 is a side view, and Fig. 5 is a detail view.
This invention has relation to machinery for the manufacture of spoked wheels 5 and it consists in combining with a circular saw, which is suitably mounted on a table, a centeringpost which is movable up to and from the saw, and a vertically-adjustable wheelsupport, whereby the ends of inserted spokes of wheels of ditferent diameters can be truly sawed ready to have tenons formed on them, as will be hereinafter explained.
In the annexed drawings, A designates the frame otl the machine, on which are three tops, B B1 B2. C designates a carriage, which is arranged below an opening' through the top A B, and suitably guided, so that it can be moved up to andfrom a circular saw, S. To this carriage is rigidly secured a vertical post, a, which is designed to receive the hub of a wheel and center the same. Then a spoked hub is put on the post a it is supported on a shelf, b, through which the post e-passes freely. The shelf I) is secured to the upper end of a rack, b', which is guided in the carriage and movable up and down by means of a pinion spur-wheel, c, which is keyed on a horizontal rod, c1, having a T-handle on its outer end. tod c1 passes through a long guide, c2, which allows it to move along with the carriage. The shelf' and its rack are sus"- tained in place, when adjusted, by means of a ratchet-wheel, d, and a pawl, and by means of a tripping-rod, E, (shown inFig. 2;) the pawl last referred to can be detached from the ratchet wheel d when it is desired to lower the shelf b. C designates a horizontal rack, which is secured to the carriage C and supported in a guide, F, below the table-tops B B1. Vith the teeth of this rack a pinion spur-wheel, c, engages, which wheel is keyed on a horizontal shaft, cl, and provided on its outer end with a crank, c2. By these means the carriage C is adjusted up to or from the saw S. The saw S is applied on an arbor, f, which is supported in bearings beneath the raised top B', and provided with two belt-pul leys, s s1. The ends'of the arbor f extend out beyond the sides of the raised top, and one end is constructed with a tenon-cutter, g, and the other end with a boring-bit holder, h. On the saine side of the top B1 as the bit-holder h is another bit-holder, t', and a shaft, j, which carries a pulley, s2, and receives rotation from the pulley s1 by means of a belt. At 011e corner of the frame A, and applied on a vertical shaft, H, which is driven by a belt, is a circular cutterhead, I, presenting a concave pc riphery armed with cutters for shaping and rounding up fellies. The bits used in the holders /L and 'L' are for boring tenen-holes in the fellies, and also dowel-holes. Between the tenon-tool g and the post a is a spokecla-mp, G, consisting of a notched piece and a hand-lever. This clamp G is in close relation to the said tcnon-tool, and is designed for rigidly holding the spokes while forming tenons on them.
The operation is as follows: After the spokes have been driven intol a hub the latter is applied on the post a. The spokes are then moved up to the saw S by adjusting thc carriage O, and their ends are out oft', so as to leave the spokes of an equal length.` The carriage O is then adjusted back and the shelf I) lowered so as to bring all the spokes in the same plane with the arbor f. Each spoke is then presented to the cutter y and a tenon formed on it.
VThe saw S is also used to cut fellies of the proper length.
It will thus be seen that the spokes can all. be cut of a uniform length and tenoned with out removing the wheel from its centering post a.
Yhat I claim as new, and desire to secure hereunto subscribed my name in the presence by Letters Patent, sof two witnesses. v The centering-post a, applied to ay (1m-ringe, v OLVER J. DOERTY.
C, in combination with the vertically-adjust- Vitllesses:
able shelf b and a saw, S, substantially as and J. M. RIGKETS,
for the prposes described. J. H. JOHNSTON,
