ANTOINE SOURSIN, OF ST. LOUIS, MISSOURI.

IMPROVEMENT IN WHIFFLETREE ATTACHMENTS FOR VEHICLES.

Specification forming part of Letters Patent No. 137,103, dated March 25, 1873.

To all whom it may concern:

Be it known that I, ANTOINE SoURsiN, of St. Louis, in the county of St. Louis and State of Missouri, have invented a certain Improved Collar Attachment for Whifiietrees, of which the following is a specification This invention relates to an improved combination, arrangement, and construction of parts, to constitute a collar attachment for whiffietrees, as will now more fully appear.

To enable those herein skilled to make and use my said improvements, I will now more fully describe the same, referring to- Figure l as a side view; to Fig. 2, as a front view; to Fig. 3, as a longitudinal sectional elevation.

A represents the double-tree or sway-bar; B, the single-tree. Through the double-tree A passes the draw-bolt G. The bolt 0 is formed tapering, and inverted in position, so as to have its thickened portion in the rear, clearly shown in Fig. 3. Forming part of the draw bolt is a head, 0, which receives the draftstrain; and it will be noticed that, as the said bolt is strongest at c, the draftstrain is conseqently exerted upon the point where the bolt is the strongest. I) is the clip. The clip being formed separate from its draw'bolt O, is united to same by a nut, 61, which is seated in a corresponding socket, with which the clip is provided. (See Fig. 3.) The clip D, thus firmly connected to draw-bolt 0, turns freely with same, and accommodates the vertical motions required of the singletrce. E represents my improved spring-collar. The said collar is cast or otherwise formed to consist of one piece, conforming to the single-tree part, which it envelops. At the bottom the collar E has its opened parts formed with opposite-positioned ears 6 6 which are united by screw-bolts 6 (See Figs. 1, 2, and 3.) By means of the screw-bolts c the spring-collar can be made to close firmly the single-tree part, prevent its turning, and especially follow up wear of same. Further, the ears 6 6 enable me to avoid a hinge-joint in front, and being positioned at bottom, the front of collar is free and neat in appearance. Further, forming part. of the collar E and positioned in the rear thereof, is a lug, E.

The collar, by its lug E, is fitted to engage the clip D, and the connection is made by a bolt, F, secured by nut f. 3.) The bolt F allows free horizontal motion of single-tree, and said bolt is prevented from turning in the clip by a lug, f, engaging a mortise in the clip.

My improved attachment for whiffletrees of vehicles is more readily cast or formed, is cheaper, more durable, its parts readily supplanted and connected, and otherwise possesses superior advantages to ordinary metallic collars and tug-straps.

Having thus fully described my said i1nprovements, what I claim is- The combination of spring-collar E, formed with a lug E, and united at its bottom by ears 0 c screw-bolts 0 bolt F, clip I), drawbolt 0 of tapering'form and having head 0, arranged to operate as and for the purpose set forth.

'In testimony of said invention I have hereunto set my hand in presence of witnesses.

A. SOURSIN.
