ANTIRATTLING THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 626,862, dated June 13, 1899.

' Application filed March 13, 1899. $erial No. 708,804. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE HENRY FER- NALD, of North East, in the county of Erie, in the State of Pennsylvania, have invented new and useful Improvements in Quick-Shift Antirattling Thill-Oouplings, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to quick-shift antirattling thill-couplings.

My object is to so construct a quick-shift antirattling thill-coupling that when the bail is slipped over the rear end of the clip-bar it will not slip off while the lever is being operated to produce tension upon the spring to hold the bail in place.

My further object is to improve the detail construction and general utility of devices of this character; and to that end my invention consists in several new and novel features of construction and combination of parts hereinafter described and which are specifically set forth in the claim hereunto annexed. It is constructed as follows, reference being had to the accompanying drawings, in which' Figure 1 is a side view of my device, showing it in the position it would occupy after insertin g the bolt into the eyes of the thill-irons, the bail being placed over the end of the clipiron ready to produce tension upon the spring to hold the parts in place. Fig. 2 is a crosssection through the center of what is shown in Fig. 1, except that it shows the lever partly depressed and showing the position which the bolt in the lever would take with respect to the eye when putting tension upon the spring. Fig. 3 shows a similar view when the lever is forced clear around to hold the spring in position. complete and when looked, as shown in Fig. 3.

a are the ordinary thill-clips, suitably secured in the ordinary way to the axel a, and b is a thill-iron adapted to rest and fit between the clips in the ordinary way, and b is a clipbarsecured in the ordinary way.

c is a U -shaped bolt, one end a being adapted to pass through the eyes of the clip and Fig. 4 is a front view of the device.

thill-iron when in use, thereby preventing play, and consequently noise or rattling, and the opposite end is provided with an elongated eye f. The strap eis constructed somewhat hook-shaped, the one end being adapted to be secured by a rivet or otherwise to the spring 6, and the opposite or hook end engages the end cl of the bolt 0 at the recess d. By providing the end d with recesses and allowing I the strap e to engage with it, it prevents lateral displacement.

g-is a lever having an eye g and bolt h at one end and shoulder Z, to which shoulder is loosely secured a bail m, said bail being so constructed as to form a recess 'm at its upper end to pass around the clip-bolt o and to form a bearing on top of the clip-bar b. The

bolt h is adapted to engage with the elongated eyef in the strap-spring.

To operate my device, I first pass the end 0 of the U-shaped bolt into the eyes of the clip and, iron, holding it insuch position that the curved port-ionfof the strap-spring will allow it to pass in. Then by a backward movement I allow it to assume the position shown in Fig. 1 and place the bail m upon the clipbar, as shown. Then by forcing the lever g down from the position shown in Fig. 1 to that shown in Fig. 2 the bolt h travels to the inner bearing of the elongated eye f, so that the future movement of the lever 9 tends to draw the bail downwardly and slightly forward,thereby preventing the upper end thereof from being disengaged from the bar I). When the lever passes at the point down and forward of the fulcrum-point in the shoulder l, the bar h begins to move rearwardly in the elongated eye f until it moves to the extreme end and the lever is held in position by the end, a lever pivoted in said eye, and a bail to tension of the spring, as shown in Fig. 3. pivoted to said lever, as set forth.

Having described my invention, what I In Witness whereof I have hereunto set my elairn, and desire to secure by Letters Patent, hand this 1st day of March, 1899. 1s

A quick-shift antirattling thil l-coupling, GEORGE HENRY FERNALD' comprising a strap-spring curved at one end, \Vitnesses: and having a U-shaped bolt secured thereto, J. L. GREEN,

and having an elongated eye at its opposite H. L. FENTON.
