JOHN ALBRIGHT, OF BURLINGTON, IOWA.

NECK-YOKE CENTER.

SPECIFICATION forming part of Letters Patent No. 406,250, dated July 2, 1889.

Application filed November 14, 1888. Serial No. 290,826. (No model.)

To all whom it may concern:

Be it known that 1, JOHN W. ALBRIGHT, a citizen of the United States, residing at Burlington, in the countyof Des Moines and State of Iowa, have invented certain new and useful Improvements in Neck-Yoke Centers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to neck-yoke centers, and has for its object to provide a center which will allow an easy movement of the pole in all directions. In centers of this general style the constructions are such that the wear upon the parts is unequal, thereby weakening the parts and increasing the liability of breaking, also causing much annoyance occasioned by the rattling of the parts. I overcome these objections by constructing a neck-yoke center composed of an outer ring provided with two horizontal pivot-points engaging eyebolts in the yoke, and a pole-ring vertically pivoted in the said outer ring at points diametrically. opposite each other, whereby I compensate for all vertical and lateral motion of the pole due to the unevenness of the travel of the horses and to the wheels of the vehicle striking obstructions in the, road; also by providing the outer ring with rounded projections, against which the lnner ring bears independent of its pivotal points, thereby relieving the pivots of excess ive strain.

I will now proceed to describe my invention more fullyin connection with the accompanying drawings, wherein- Figure 1 is a perspective view of partof a neck-yoke with my invention applied thereto. Fig. 2 is a vertical central cross-section of the same. Fig. 3 is a front elevation of a modification.

The same letters of reference indicate identical parts in all the figures.

In the drawings, A represents the neckyoke, and B the outer and C the inner or pole ring. The yoke is provided with two eyebolts D D, the shanks of which pass through the yoke and are rigidly secured therein in any suitable manner. The outer ring B is provided with two pivotal points E E, adapted to engage the eyes of the bolts D D,said pi votal points having shoulders e e, which bear against the eyebolts D D. The inner faceof the ring B is provided with seatsG G Vertically and diametrically opposite each other, said seats having rounded projections F F. The inner or pole ring 0 is provided on its outer face with two enlargements or bosses g g, adapted to fit in the seats G G and bear against the projections F F, said pole-ring being pivoted in the seats G G by means of pins II II passing into the outer ring B, and secured therein in any suitable manner.

In order to prevent the rattling of ring 0 on the pole and prevent the wearing of the pole, I line said ring with leather or any suitable material.

I have shown and described the rounded projections F F as being only on one side of the ring 13; but, if found desirable, I may provide both sides of said ring with the rounded projections.

By the construction hereinbefore described it will be seen that in holding back the vehicle the pole-ring will press against the rounding projections F F independent of the pivotpins II H, and thereby relieve the pins of excessive strain.

In the modification shown in Fig. 3 I have omitted the rounding projections F F on the outer ring and simply provided it with seats or enlargements g 9, through which the pivotpins pass. 7

\Vhat I claim, and desire to secure by Letters Patent, is

1. The combination, with a neck-yoke, of two eyebolts secured thereto, a ring horizontally pivoted in the eyes of said bolts, and a pole-ring vertically pivoted at diametricallyopposite points in said outer ring, substantially as described.

2. The combination, with a neck-yoke, of

two eyebolts secured thereto, a ring having 5 IOO ring and having bosses thereon which bear In testimony whereof I afiix my signature in IQ against the concaved faces of the said propresence of two Witnesses. ectlons F F, substantially as described.
