SUMMARY An object of the present invention is to provide a buckle in which the body section and the lever section are constructed and combined so that the buckle is capable of producing a degree of tension which is large in proportion 'to the small size, simplicity and low cost of the buckle. t
The invention particularly contemplates a sheet metal buckle the construction of which enables the buckle to produce alarge degree of tension in a strap with a minimum of danger of bending, twisting or warping of the sheet metal buckle sections and with minimum effort by the operator.
More especially the invention provides'a bodyfor connection atone end to one end of a strap and a strap-tensioning lever pivotally connected at one end to said body intermediate the ends of the body, said body "having a strap guide bar between its ends and betweenthe'bottom side of the body and an axial plane of said pivotal connection that is approximately parallel to said bottom side and saidle'verhaving astrap-tensioriing bar around which a portion of said strap is looped so that as the lever is swung about saidpivotal connection said strap tensioning is disposed on'thesame side of said axial plane as said guide bar for tensioning the strap and is movable to the opposite side of said plane into riontensioning position.
The buckle embodying the inventionalso reduces to' the minimum the possibility of slippage of the strap when the tensioning lever is in clamping position.

FIG. 10 is a longitudinal sectionalviewof the buckle shown in FIG. 9 and with the strap attached thereto, showing the lever in tensioning position in solid lines and in nontensioning position in dot anddas h line's.
' DESCRIPTION OF THE PREFERRED EMBODIMENTS Specifically describing the form of the invention shown'in metal body .sec-
connected together by crossbars l 2 and 3 and 4 the latter of which constitutes means for connecting one end of a strap B to the buckle as indicated at 5 in FIG. 4. n
A strap tensioning lever C is approximately U-shaped and has two parallel sidepieces 6 rigidly connected at one end by handle plate 7 and having the other end pivotally connected by rivets 8 to the respective sideplates 1 intermediate the ends of the body section. A strap tensioning bar 9 is carried by the lever C and has its ends rigidly connected as by riveting to the sidepieces 6 and the body section A has a strap guide bar 10 rigidly connected as by riveting to the sideplates l. The guide bar is disposed between the approximately flat bottom side of the body section and an axial xx plane of the pivotal connection 8 that is approximately parallel to the bottom side of the body section and also between" the strap attaching bar 4 and the pivotal connection. t g
In threading the strap B through the buckle the lever C is swung into nontensioning' position as shown in FIG. 4. The end of the strap opposite the end 5'c'onnect'ed to the body section is threaded through the slot between the plates land 3 of the body section and then beneath the guide bar 10, after which "pulled to preliminarily tighten the strap around the load.
Then, to tension the strap tightly around the load the handle plate 7 is gripped by the hand of the operator and pulled so as to swing the lever C in a clockwise direction in FIG. 4 so that the strap is looped and guided around the guide bar 10' and the strap tensioning bar 9 draws the strap taut as shown in FIG. 5. The lever is swung until the axis of the tensioning bar 9 is disposed between said axial plane xx of the pivots 8 and the axis of the guide bar 1 0 so that the tension on the strap holds the lever in clamping position, although if desired additional means, for example projections 11 on the lever to snap resiliently frictionally into recesses 12 on the body section may be provided.
A modification of the invention is shown in FIGS. 6, 7 and 8 wherein the body section E which is similar to the body section A has two approximately parallel side plates 13 which are rigidly connected by crossbars l3, l4, l5 and 16 the latterof which has one end of the strap F connected thereto as indicated at 17. The body section has a strap guide bar 18 which in the present instance is shown as stamped integrally with the side plates with the stamped out portion doubled upon itself to provide two thicknesses of the sheet metal in the guide bar.
The strap tensioning lever G has parallel sidepieces l9 rigidly connected at one end by a combined handle plate and strap tensioning bar 20 which is stamped up integrally with the sidepieces and is formed of two superposed thicknesses of the sheet metal. The other ends of the sidepieces are pivotally omitted and with the lever' connected by rivets 21 to the respective side plates 13 of the body.
In use of the buckle, the lever G is swung first into nontensioning position as shown in FIG. 6 and the strap is threaded around the guide bar 13 and the tensioning bar 20 in the same manner in which the strap is threaded around the guide bar and the tensioning bar 9 in FIG. 4. To tighten the strap around the load H, the free end is preliminarily manually pulled taut as shown in FIG. 6 after which the lever is gripped at its free end and swung clockwise into the final tensioning position shown in H0. 7. Here the rounded edge of the tension bar around which the strap is looped is located between the approximately flat bottom side of the body section and an axial plane of the pivotal connection 21 which is approximately parallel to said bottom side of the buckle so that tension on the strap holds the lever in clamping position without additional locking devices, although if desired means such as projections 22 may be provided on the lever to resiliently frictionally coact with recesses 23 on the sideplates of the body section.
The sheet metal buckles shown in FlGS. 1 through 8 inclusive are strong and permit the buckles to produce a large amount of tension in the strap with a minimum of danger of bending, twisting or warping of the sheet metal buckle sections and with minimum effort by the operator. However, in many instances it may be desirable to provide less expensive buckles that are especially adapted to use where low degrees of tension on the strap will suffice. FIGS. 9 and 10 show a modification of the buckle wherein both the body section I and the lever section K are formed of heavy wire. The body section I is approximately U-shaped and has approximately parallel side pieces 24 rigidly connected by a crosspiece 25 which serves as means of connection for one end of a strap L. The ends of the sidepieces are angularly disposed to the general plane of the side pieces and formed with eyes 26 to which are pivotally connected the respective side arms 27 of the lever K. As shown, the lever K is approximately U-shaped and has the end portions of the arms 27 angularly disposed and rotatably fitted in the eyes 26 as indicated at 28. I
A strap guide bar 29 is shown in the form of a strip of sheet metal which has its end portions looped around and rigidly secured to the side pieces 24 of the body section, while the strap tensioning bar 30 is shown as having its ends looped around and rigidly secured to the arms 27 of the lever section K. The guide bar 29 is disposed between the approximately flat plane of bottom side of the body section and an axial plane of the pivot eyes 26 that is parallel to said bottom side, and is also disposed between the crosspiece 25 and the eyes 26. The strap is threaded through the wire buckle in substantially the same manner in which the straps are threaded through the sheet metal buckles, as shown by FIG. 10 where the lever K is shown in strap tensioning position by solid lines and in bottom position by dot and dash lines.
