SWINGLE'IREE-CLIP.

Specification of Letters Patent.

Patented Nov. 14, 1911.

Application filed August 31, 1910. Serial No. 579,816.

To all whom it may concern:

Be it known that I, LUoY B. HARTZELL, a citizen of the United States of America, residing at Murray, in the county of Galloway and State of Kentucky, have invented new and useful Improvements in Swingletree- Clips, of which the following is a specification.

This invention relates to swingletree clips, the object of the invention being to provide a clip of this character which can be connected with the swingletree without resorting to permanent fastenings or the like.

A further object of the invention is to construct the clip from a single piece of springy material such as wire, bending the same into locking engagement with the swingletree and forming the same to provide a retaining element for engagement at one side of the tug to hold the same in its applied position.

In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views :Figure 1 is a fragmentary perspective view of a portion of a swingletree showing my improved clip applied thereto and operatively associated with the tug.

Fig. 2 is a side elevation thereof with parts broken away to clearly disclose the invention.

The swingletree clip consists preferably of a single piece of springy material, preferably wire. The wire is bent on. itself to provide a relatively long arm 1 and'a movable arm 2. The arm 2 is connected with the arm 1 through the coiled portion 3 which is seated in the correspondingly formed recess 4: at the outer end of the swingletree. The long arm of the clip extends longitudinally of the swingletree and its extremity is bent upwardly, as shown at 5, to extend through a correspondingly formed passage in the swingletree and then downwardly to form a retaining spur 6 which is bent into the swingletree and slightly impressed therein to insure a perfect and most efficient fastening. The free or movable arm 2 of the clip extends upwardly in spaced relation to the sWinglet-ree at one end thereof, as clearly shown in the drawing. The

extremity of the said movablearm is bent downwardly to form a keeper 7 for the tug strap 8. The tug strap 8 is of usual construction, being provided with the eye 9 to receive the end of the swingletree, as clearly shown in Fig. 1 of the drawing. The keeper 7 extends into a recess 10 in the swingletree, and as illustrated, its lower end is offset or hooked, as at 11, to engage a stop 12. The stop 12 is preferably in form of a bolt which extends through the swingletree and which passes through the walls of the recess 10 in position to be engaged by the hooked end 11 to prevent the same from being entirely withdrawn from the said recess 10. This construction has been found most desirable in that the tendency, under the spring action of the clip, of the same to expand is resisted and the clip is held in the most 'efiicient manner in its applied position to the swingletree.

In operation of the device herein described, it may be stated that the tug 8 is threaded onto the swingletree so as to occupy the position shown in Fig. 1 of the drawing. Under the spring action of the clip the short arm 2 will tend to assume the full line position shown in Fig. 2 so as to cause the keeper portion 7 of the arm to lie directly at one side of the tug to hold the same against working off of the swingletree. The short arm 12 is pressed downwardly to occupy the position shown in dotted lines in Fig. 2 when it is desired to remove the tug from the swinglet-ree. The construction is such that when the short arm is pressed to the said dotted line position the surface 7 at the point of intersection of the said short arm with the keeper 7 will curve directly into the recess 10 so as to prevent the keeper from acting as an obstruction when removing the tug, it being understood that the eye of the latter can be conveniently slipped over the said curved surface.

I claim:

A swingletree clip consisting of a swinglet-ree having an opening in its end and recesses located near said opening and one face thereof, a wire bent upon itself to provide a relatively long detachable arm and a short movable arm and a spring coil conacross the recess adapted to limit the out nesting said arms, the longer arm being exward movement of the short arm. 1 tended through the swingletree and clenched In testimony whereof I afiix my signature thereagainst, and the shorter arm having in presence of two witnesses.

an angular terminal provided with a stop LUCY B. HARTZELL. and movably disposed in the recess, and the Witnesses:

spring coil being disposed in the end open- CONN LINN,

ing of the swingletree, and a pin extending S. H. Dnns.
