Application filed May 4, 1915. Serial No. 25,703.

To all 'whom it may concern Be it known that I, FRANK S'. REINHARDT,

a,A citizen of the United Statesof America,

and a resident of Memphis, county of Shelby, State of Tennessee, have invented certain new and useful Improvements in Bale-Ties, of which the following is a full and clear specification, reference being had to the accompanyingdrawin'gs, in which- Figure 1 isv a sectional view of my improved buckle as it appearsin use;` Fig. 2 a front elevation of the same, the bale' being omitted in both views; and Fig. 3 is a transverse section on the line 3-3 of Fig. 2.

The object of my invention is to provide a buckle which shall be simple and inexpensive to manufacture and to apply, and which at the same time shall be so constructed that slipping of the bale-band through the buckle will be rendered practically impossible, irrespective of the bale pressure on the band, yas more fully hereinafter set forth.

My buckle consists of a metal plate a provided at its upper edge with a transverse slot b through which, in the usual manner, the depending end of the bale-band is passed to connect the buckle thereto. Across the lower end of the plate a is formed another slot c somewhat longer than the width of the band, but having its lower edge CZ shorter than the width of the band, the end walls e of this slot being inclined from where they join the lower edge d upwardly. Formed integrally with the plate, along the upper edge of the slot c is a pair of inwardly extending teeth each of which is tapered to substantially a V form. These teeth f are transversely in alinement and are separated a sufficient distance to cause their pointed ends to lie in the path of the band at the respective side edges thereof.

In applying my device, the depending end of the band is looped through the upper slot b in the usual manner, its free extremity lying against the inner face of the band at a point above the buckle. The other end of the band is passed through the slot c and drawn upwardly past the teeth f and arranged so that its upper extremity will lie against the inner face of the band at a point above the buckle. With the band arranged in this manner. it will be seen that when the bale is released from the press and allowed to expand. the pressure will draw the band taut and thus cause the edges of the band to be crimped at g by the -inclined cam edges `e and be indented at 7L., at opposite edges of the band, by mea-ns of the prongs or teeth f. Thus crimping orl bendingthe edges of the band where it engages the buckle provides an effective and simple means for preventing slippage of the band, and this means for preventing slippage -will be just as eective with a lightly pressed bale as with a heavily pressed'one.

A feature of importance -lies in utilizing the lexpansive tendency of the bale to bring Vabout the interlocking of the buckle and the band, and it will be seen also that the interlocking is made especially effectual by reason of the fact that the crimps or indentations h Vare made in a direvction opposite to the crimps or bends g.

It will be observed that with my construction, the interlocking of the band with the buckle at the points g may be obtained without notching the edges of the band, the edges of the band being smooth and straight as with the common form of bale band. As is obvious, notches not only weaken the band but alsoy add materially t0 its cost of manufacture and it is, therefore, greatly advantageous to avoid their use. It willbe seen also that in order to do away with the notches in the edges of the band and cause the interlocking crimps at C/ to be automatically formed when the band is drawn taut, it is essential that means be provided at the upper edge of the slot cwhich shall extend inwardly and cause an abrupt inward bend inV the band and thus insure the crimping at g when the band is drawn taut. It will be observed further that my buckle is self-fastening; that it can be tied or fastened without the necessity of first bending the free end of the band; that it eliminates the possibility f of initial slack in the band or in the buckle; that the initial tightness does not depend upon the accuracy of the laborer'who applies the buckle; that it is impossible to applv the buckle incorrectlv. since if applied at all the band will be held firmly and permanently in its initial position: and that the greater the strain on the band the tighter it will be held by the buckle.

' Having thus described my invention, what I claim is: Y g

1. A bale banding device consistingv of a straight-edged band. a tie-buckle consisting of a plate having means at one end for attachment to one end of the band and also provided with a transverse slot nearits other end, this slot being longer than the Width of the band and having one of its edges shorter than the Width of the bandfthe end Walls of the slot being inclined from their juncture with said shorter edge toward the longer edge of the slot, laterally-extending means being provided at the longer edge of the slot for causing an abrupt bend in the band, for the purposes herein set forth.

2. A bale banding device consisting of a straight-edged band, a tie-buckle consisting of a plate having means at one end for at` tachment to one end of the band and also provided with a transverse slot near its other end, this slot being longer than the Width'of the band and having one of its edges shorter than the width of the band, the end Walls of the slot being inclined from their juncture of the opposite edges ofthe band, whereby.

when the free end of `the band is threaded through the slot and passed behind `said teeth'the expansive tendency of the bale lWill cause said teeth to crimp the `two edgesof 1 the band and the said inclined end walls will crimp the two edges of the band in: the .opposite direction.

In testimony whereofv I hereunto aiiX my signature.
