, BUCKLE Application filed September 28,1916. Sria n'o. 12'2",679'.

To all whom it mag camera. f

Be it known that I, J giCKSON G. Smarties, a citizen of theUnited States, residingat Pontiac, in the county of Oakland and State of Michigan, have inventedfce'r-tain new and useful Improvements in Buckles, of which thefollowing is a specification,reference-beinghad therein to the accompanying drawing.

This invention relates to bucklesadapted to join the ends ofapparel-belts', harnessstraps, and the like, and generally' i'or use wherever a fastener of this kind is required, and it is an object of the invention "to provide such a fastener with means whereby it will be easy to buckle and unbuckle, will reliably hold the connected parts together, and will present a neat appearance."

lVhen read in connection with the description herein, thedetails of construction and arrangement of parts contemplated by the invention will be apparent from the accompanying drawing, forming part hereof, wherein an embodiment ofthe invention is disclosed, for purposes of illustration.

lVhile the disclosures herein 110W are considered to exemplify a preferableembodiment of the invention, it is to be-understood that it is not the intention to be limited necessarily thereto in interpretation of the claim, as various changes within the limits of the claims can be made without departing from the nature and spirit of the invention.

Like reference-characters refer to corresponding parts in the views of the drawing, of which Figure 1 is a plan View;

Fig. 2 is a side view;

Fig. 3 is a longitudinal sectional view; and

Fig. 4 is a transverse sectional view.

Having more particular reference to the drawing, the buckle includes a base plate formed of two layers of material 5 and 6 riveted or otherwise secured together. The plate is formed at or near one end with a transverse elongated opening 7 to receive a strap or the like whereby the buckle is connected permanently thereto. At the opposite end, the under or lower layer 5 is turned upwardly as a flange or abutment 8, which abuts and extends slightly over the end of the outer or upper layer 6 at an acute angle toward th'eother end ,of'the buckle. I

Commencing at the free end, that'isthe end opposite to the opening 7, and extending only a part of the length of the base plate, the material ofthe outerlayer6 extends outwardly on each side and then'over'and in substantially parallel relation to the contour of the plate, whereby there are formed 'side walls ;9 and a' cover-wall 1,0 of akeepercasing-closed at the sides and open at the ends. A :recess 11 is formed in-the edge'of the cover-wall opposite-to the free end of the buckle and midway between the "sides. Each side wall 9 'at 'the' end opposite the free end of the buckle is cut away to form open recesses12." In the vicinity of the atta ched end of the buckle, the outer layerti is upturned, to form a transverseiab t- Inent13. n a A keeper 1 1,- of approximately the ';same length of'the keeper-.casing,' .is slidableon the base plate and "within and outwardly of the casing It has upstanding parallel marginal side flanges 15 that contact with the vSide walls of the casing and that are ofsu fli cient height to contact at their ed'ges'with the cover-wall ofithe casing,.whereby the keeper'is held down on the plate. The outer faces of the flanges 15 are knurled or otherwise-roughened, as shown at"l6,j to afford a reliable hold to the fingers in moving the keeper, and the recesses 12 permit access thereto when the keeper is entirely under the cover. The keeper has a fixed fastening-tongue 17 positioned substantially mid way of its sides at or near the end opposite to the free end of the buckle, the tongue is disposed at an inclination toward the permanently attached end of the buckle, that is in a direction opposite to the direction of pull of a strap or the like against the mem ber permanently attached to the buckle, and it can seat in recess 11 of the cover-wall of the casing. The keeper is held permanently on the base plate by the casing, by the abutment 13, which limits its outward movement from the cover, and by the oppositely-disposed abutment 8, which stops its movement when it is entirely under the cover and prevents its detachment from the buckle at the free end. The relative arrangement of the parts is such that, when the inner end of the keeper contacts with the abutment 8, the

tongue seats in and contacts with the edge of the recess 11, and, when the keeper is moved outwardly of the casing, it is stopped by the abutment 13 before it is entirely dislodged from the casing.

When it is desired to attach the end portion of a strap or the like to the buckle, the latter is inserted through the casing at the opening at the free end and passed over the keeper between its side flanges, and, the keeper now being at the outward limit of its movement from the casing one of the apertures in the strap or the like is brought to engagement with the keeper-tongue. Then the keeper is drawn under the casing, and the strap thereby is held down in reliable engagement with the tongue. The inwardly-inclined flange or abutment 8 facilitates the insertion of the strap or the like into the casing. Preferably, when inser-.

tion is commenced, the keeper should be inside of the casing with its end abutting the flange, so that there will be no liability of the strap-end catching on the end of the keeper. Thereafter, as the strap is pushed through the casing, the keeper will be moved outwardly to position with its tongue away from the end of the casing where it is easy to bring the strap into engagement with the tongue. Owing to the inclination of the tongue in the direction opposite to the pull of the strap or the like, the latter is not liable to become dislodged from the tongue after it is brought to engagement and during movement of the tongue to position against the end of the keeper-casing. The strain imposed on the tongue after the parts have assumed the locking position is sustained by the flange 8 and by contact of the naeaoso tongue against the keeper-casing. Thus the tongue has two points of support, one at each endwhere it is connected to the base of the keeper and where it engages the keeper-casing. Therefore, liability of the tongue being broken off by leverage action under great strain, as would be the case if the pull was sustained only at the place of connection of the tongue to the-keeper, is obviated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A buckle comprising a base-plate having upwardly-projecting flanges at opposite ends and marginal side walls and a coverwall forming a keeper-casing, there being an open recess in one end of the cover-wall, a keeper slidable longitudinally within the casing between said end flanges and having upstanding parallel marginal side flanges abutting the side walls of said keeper-casing and operating on contact with the coverwall thereof to retain the keeper On said base-plate, and an upstanding tongue fixed to said keeper and positioned to seat in said recess in the end of the cover-wall upon movement of the keeper in one direction, the buckle being adapted to receive a strap between the marginal flanges of the keeper and under the cover-wall of the keeper-casing and said tongue being adapted to extend into an opening in the strap.

In testimony whereof I afliX my signature in presence of two witnesses.
