GEORGE E. FARISS, OF NOBLESVILLE, INDIANA.

WHIFFLETREE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 639,555, dated December 19, 1899.

Application filed June 21, 1899. Serial No. 721,341. (No model.)

To all whom it may concern.-

Be it known that LGEORGE E. FARISS, a citizen of the United States, residing at Noblesville, in the county of Hamilton and State of Indiana, have invented certain new and useful Improvements in Whiflletree-Gouplers; and I do declare the following to be a f ull,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 coupling devices for coupling the whiffletree to the cross-bar; and the object is to provide a simple, inexpensive, neat, strong, durable, and absolutely-noiseless device of this character.

To this end the invention consists in the construction, combination, and arrangement of the several parts of the device,-as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a perspective View of the central portion of the bar and whiffletree pivotally connected by my improved coupling. Fig. 2 is a transverse section through the coupling.

1 denotes the shaft-bar, in the center of which is formed a cylindrical pocket 2 toreceive the correspondingly-formed shank 3 of the bar-socket 4, the upper end of which is formed with an annular vertical flange 5.

6 denotes the pivot-bolt, the rectangular head 7 of which engages the lateral notches 8 8, formed in the lower end of the socket 3.

9 denotes the singletree, the lower face of which is formed with an inverted pocket 10 to receive the internally-threaded shank 12 of the coupling-socket 13, the lower end of which terminates in an annular flange 14, which is concentric with and has a bearing in the encompassing socket 4 in such a manner that the lower face of the singletree bears against the upper edge of the bar-socket flange 5, so

as to produce a practically noiseless joint when in actual service. It will also be noted that the lower face of the singletree completely covers the entire socket 4, and thereby forms a dust-guard for the hearing.

The accompanying drawings show my invention in the best'form now known to me; but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of my in vention as set forth in the claims at the end of this specification.

Having'thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. A coupling of the class described, comprising the bar socket and the couplingsocket, one of which is adapted to encompass the other, and a bolt having a threaded engagement with one of said sockets and a notched engagement with the other, substantially as and for the purpose set forth.

2. In combination, the shaft-bar 1 formed with the pocket 2, the bar-socket 4 formed with" an annular flange 5 and a cylindrical shank 3 seated in said pocket and formed with radial notches 8 8, the pivot-bolt 6 mounted in said shank and having its head seated in said notches, the singletree 9 formed with the pocket 10, the coupling-socket 13 formed with the shank 12 having a threaded engagement with said bolt and seated in said socket 13, and a concentric flange 14 extending into said bar-socket, so that the contiguous face of the whiffletree will have a bearing on the barsocket flange 5, substantially as and for the purpose set forth.

Intestimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE E. FARISS.
