THILL FOR SULKIES.

SPECIFICATIN forming part of Letters Patent No. 403,079, dated May 7, 1889.

Application filed March 11', 1889.

T0 aZl w7wm it may concern:

Be it known that I, SAMUEL TOOMEY, a citizen of the United States, and a resident of Canal Dover, county 0E Tnscarawas, State .of Ohio, have invented a new and useful Improvement in Thillsfor Sulkies, of whioh the following is a full, clear, and exact description, reference beinghad to the accompanying drawings, making part of this specification.

My invention relates to improvements in sulkies, particularly to the class used for speeding horses; and it oonsists in a peculiar construction of thill by which a minimum in size and weight is reached and yet retain the necessary amount of strength, as hereinafter described, and set fort-h in the claim.

Figure 1 of the accompanying drawings, is a view in perspective of a sulky, illustrating my invention. Fig. 2 is a plan view of thill; and Fig. 3 is a view of the cross-section, as from 00 to :12, full size.

In sulkies for speeding horses it is essential to the best resnlts that the thills should be absolutely nnyielding at those points under the feet of the driver,'and at the same time that the thills should be as light as possible consistent with such rigidity. To this end I construct the thill of the form shown in the cross-section, Fig. 3, taken on the lines ce 90 in Figs. 1 and 2, which I call an irregular oval, oblique, the longest diameter being oblique and on a line as from B to C. The lower outside portion or bulge serves to make the thill unyielding to the outward and clownward Serial No. 302,841. (No model.)

pressure of the drivers feet, as well as to prevent the draft and jar on the axle-spindles; and to overcome any tehdency to yield clownward I form a bulge inwardly below the horizontal axis and outwardly on the opposite side above the horizontal axis. These bulges are shown connected by the line D E in the drawing Fig. 3, the line G H showing the general direction of the clownward pressure.

Between the points B, C, D, and E the contour of the thill is arched just enough to retain the stiffening tendenoy of the curved form over the straight, and at the same tirne is sufficiently flattened to get rid, as far as possible, of unnecessary material.

The result as found in practice is a thill of very great rigidity and of unusual lightness.

Having thus fully described the nature and object of my invention, what I claim as new, and desire to seoure by Letters Patent, is

The herein described thill, irregnlar in cross-section, the diameter of the cross-section being greatest in the oblique direction from B to C, and having bulges on opposite sides, one above and one below the horizontal axis, substantially as set forth.

In testimony whereof I have hereunto set my hand this 25th day of February, A. D. 1889.

SAMUEL TOOMEY.
