BELT BUCKLE.

Application filed April '16, 1924. .Serial No. 706,978.

My invention relates to beltbuckles of the sheet metal type comprising two members to which the belt ends are respectively secured, and the primary ob ect of the inven tion is to provide a simple and inexpensive construction whereby the two members may be 'detachably connected and will be effectually held against accidental disengagement while in use. A buckle embodyingthe in vention is illustrated in the accompanying drawing, and the invention resides in certain novel features which will be hereinafter first fully described and then particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a front elevation of the improved buckle;

Figure 2 is a rear elevation of the same;

Figure 3 is a sectional view showing the manner in which the buckle members are brought into engagement;

Figure 4 is a similar view showing the action in disengaging the members;

Figures 5 and 6 are detail views of the respective buckle members, and

Figure 7 is a sectional view showing the buckle members assembled. l

The buckle members 1, 2 are struck from sheet metal and have a turned up rim or wall 3 around the entire extent of their edges on their rear sides. For convenience, the member 1 will be herein identified as the hook member and the member 2 will be called the slot member. The belt ends 4 may be secured to the belt members in any desired way, as by pivoted clamplng devices 5, and the opposed edges of the members substantially abut when the members are interlocked or connected, as will be understood on reference to Figure 1 of the drawing.

The hook member, 1, has a hook 6 at its forward edge which rises from and forms a' sulting in a cam rib or hump 9 in the bend or bight of the hook. The slot member 2 has a ledge or lip 10 extending laterally from the rim or wall at its forward edge and a slot 11 is formed along the junction of the ledge and the rim, one wall of the slot being located in the ledge and provided centrally in the rim and is provided.

with a notch 12 while the opposite wall-or the slot is located centrally with a locking nib or projection 13 mating-with the notch12. Depressions 14:

are formed in the front side of the ledge" adjacent the ends of the slot thereby formmg projections 15 on the rear side of the ledge.

The width of the slot is only slightly greater than the cross section of the book so that while the hook may be engaged through the slot there can not be any excessive play of the parts, and the nib or projection 13 will engage over the locking shoulder 7 when the members are connected. In closing the buckle, the hooks 6 are engaged through the slot 11 and the projections 15 bear against the inner surfaces of the respective hooks, as shown in Figur-eB, to serve as fulcrums while the slot member is swung or turned toward the plane of the hook member. During this suggested turning movement, the ribs 9 act as cams against the opposed wall of the slot and draw the locking nib 13 into overhanging locking engagement with the shoulder 7, the metal of the ledge and the hooks ossessing sufficient resiliency to yield to the ocking nib as the latter rides over the rim into engagement with the shoulder. Some force must be applied, however, to cause the nib to ride into engagement with the locking shoulder and an equal force must be applied to release it from the shoulder, so that the buckle members will be effectually held against accidental disengagement while in use.

In opening the buckle, the free or outer edge of the ledge is caused to bear upon the inner'side of the hook member, .as shown in Figure 4, and constitutes a fulcrum about i row slot through which thehook is engaged and a projection on the inner Wall of the slot laterally from the hook-engaging portion thereof to frictionally engage and ride across the locking shoulder on the hook mem her and to engage under the said looking I member is rocked toward the plane of the" shoulder on the hook member when the hook slot member. I

2. A belt buckle comprising a hook member ha-ving a hook at one edge, a slot memher having a slot to receive said hook, a looking element on the slot member to frictional- 1y engage the hook member, and fulcrum elements on the slot member to engage the hook member and efiectrelease or engagement of said locking element as the slot member is turned in one or the oppositedirection. 1

3. A belt buckle comprising a hook memher having a hook at one edge, and aslot member having a slot to receive said hook, a locking element on one Wall of the slot to engage the hook member, and a ledge on the slot member, said ledge being provided'with a fulcrum element to be engaged by the hook member and release said locking element.

4." A belt buckle comprising a hook memher having ahook at one side edge and provided With a rib across the bight of the hook, a slot member having a slot at one edge to receive the hook, a locking projeetion on one Wall of the slot to engage the hook member, and a projection on the slot member adjacent the opposite Wall or" the slot to fulcrum upon the inner side of the hook.

In testimony whereof, I have signed this specification. V

JOHN B. FREYSINGER.
