To all whom 'it may concern:

Be it known that I, HAnvEY E. BART, a Y citizen of the United States, and a resident of Broken Arrow, in the county of Tulsaand State of Oklahoma, have made certain new and useful Improvements in Wagon- BoXFastenrsfof which the following is a specification.

My invention is an improvement in wagon box fasteners, and consists in certain novel constntctions, and combinations of parts, hereinafter described and claimed.

The object of the invention is to provide a simple, inexpensive and easily operated device of the character specified, for holding the parts of the box firmly together, with.- out injuring the same, and which may be .quickly appliedor removed.

Referring to the drawings forming a part hereof-Fi re 1. is a front view of the improvement, ig. 2 is a View of the upper end of the improvementat right angles to Fig. 1, and Fig. 3 is a section on the line 3-3 of Fig. 1.

.The embodiment of the invention shown in the drawings comprises a rod or bar 1, having a. longitudinal bore 2 and provided with an annular rib or collar 3 at one end.

hanger bracket or jaw 4 is provided with a bearing 5 at one end, which encircles the rod above the collar, and rests thereon as shown in Fig. 1. The bearing 5 is offset upwardly from-the body the hanger and at the opposite end from the bearing an upwardly extending angular portion or lug 6 is provided.

- A rod 7 is slidable in the recess 2 of the bar, and the upper or outer end of the rod is flattened as indicated at 8. The flattened portion is bent at right angles to the rod to form a jaw 9 and the free end of the jaw'is provided with an angular lug 10. exgending substantially parallel with" the r0 An inspection ofFig, l-will show that the portion of the rod adjacent to the jaw is bent laterally as indicated at 11, and the jaw is inclined laterally toward its free end, so that the lug 10 in addition to being spaced away from the rod is offset laterally therefrom.

A cross head in the form of aT 12 is arranged at the upper end of the bar, the bar being threaded to engage the lateral branch 13 of the T, and a yoke-shaped lever 14 has the ends of its arms 15 pivoted on pins 16,: passing through 'the armsand engaging the ends of the T a 1 A hearing is slidable on therod, the said bearing comprising a plate 17 arranged on each side of-the rod above the T, and the ends of the plates are connected by bolts 18.

A curved lever 19 is pivoted intermediate 7, its ends on each bolt, and the inner end of each lever is providedwith, a gripping jaw 20, each jaw being transversely corrugated as shown for firmly gripping the. rod.

Each end of each bar is transversely perforated, and one of the-perforations is engaged .by one end of a link 21'. i The other end of the link is curved as shown at 22,

and is passed through an opening in the adjacent arm 15 of the yoke;14. Thesaid end of the link is headed onthe inner side of the arm as shown at 23, toprevent the disengagement t-hereof.. 1.

A spring; 24 encircles the rod, between the plates and the T, and acts normally to force the plates away from the T. The extremity of e ch arm 15'of'the lever 14 is bent laterally as shown in Fig. 2, so that when the lever swings downwardly into contact with the bar-1, the connection of the links with the arms is directly below the adjacent pin 16, or slightly beyond the dead center.

lock for holding the lever closed. The bar 1 may be a length of gas pipe or the like, and'the 'aws 20 are preferably of tempered steel.- T e T is provided with an-opening.

in its top for the rod 7 to pass through. The collar 3 is threaded ontothe bar an the hanger or jaw 4 is reversible.

In operation, the hanger or jaw 4-is ent gagged with the sill of the wagon box. or with an extra sill provided for the purpose,

and the jaw 9 is engaged wit-h. the top edge of the box. The side boards of the-boxmay be spaced from the box with blocks if desired Vlhen arranged as described, the rod is moved or telescoped into the bar as far as The lever 14 is then swunginto 7 possible. the position shown in Figs. 1 and 2, pulling down on the outer ends of the levers 19 and forcing the gripping" faces of the jaws into close engagement with the rod.., The bar and rod are thus locked firmly together, holding the box parts from displacement. To release the device, it is only neces-.ary to swing the bar upwardly.

It will be evident that the device consists essentiallyof a pair of telescoping members '85 The said construction provides 1 ahead, a connecting each lever with the- 'eachiend and. having .a gripplng jaw for en-' the'ro'd, a crosshead on the innero I end the. liar, a yoke shaped lever hav ng it arms'gpivoted to the cross head, a link act-mg eachlever ith the yoke shap head and-(the plates.
