Specification of Letters Patent.

Patented June 14, 1921.

To all whom it may concern: I

Be it known that I, LOWELL "N. SHIELDS, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Belt- Buclrles, of which the following is a speoification.

The present invention relates to belt buckles and more particularly to the type in which a frame is provided ith one end of the'belt anchored thereto and a clamping device is mounted for movement on the frame to clamp the other end of the belt. an object of this invention being to provide a construction which is inexpensive to manufacture, effective for securing the belt end, and durable in construction.

To this and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

F ignre 1 is face view of a buckle constructed in accordance with this invention;

Fig. 2 is an enlarged rear view;

Fig. 3 is an enlarged side view;

Fig. 4 is an enlarged longitudinal section showing the belt end clamped in the buckle;

Fig. 5 is a fragmentary longitudinal section showing the manner in which the belt is introduced through the slot in the clamp;

Fig. 6 is a plan view of the clamp; and

Fig. 7 is an end view of the clamp.

Referring more particularly to the drawings, 1 indicates the front plate of the buckle frame. which in this instance also comprises lateral side fian es 2, the rear face of the front plate serving as a surface against which the free end of the belt 3 is adapted to be held by the clamping member. The belt has one end anchored to the frame in any suitable manner as by swinging member e, in the form of a rod bent into U- shaped form and having its ends turned out wardly at 5 and journaled in the side flanges 2.

The side flanges 2 also preferably serve for supporting the clamping member 6, which in this instance is formed from sheet metal with a slot or opening 7. the edges of the sheet metal being turned laterally at 8 and 9 to provide two ribs one of which is longer than the other, while the ends of the piece of sheet metal are provided with projections 10 having laterally deflected ends 11. The side flanges 2 of the frame provided with slots, the outer ends 12 of which are arranged at a smaller angle to the rear surface of the front plate 1 than are the inner ends 13. The projections 10 operate in these slots and the laterally turned ends of the projections confine the clamping member in the slots and at the same time provide operating portions by which the clamping member may be moved in the slots. The ribs 8 and 9 of the clamping member are disposed toward the clamp ing face of the frame, and when the clamping member is positioned toward the inner ends of the slots through the laterally turned portions, the rib 9 is thrown away from the clamping face of the frame as shown in Fig. 5, while the rib 8 is brought in close abutment to such clamping face so that it is possible to pass the strap end 8 through the slot 7 and between the rib 9 and the clamping face of the frame as shown in Fig. 5. After the belt has been properly adjusted, the clamping member is moved by hand toward the outer ends of the slots so that the rib 9 will clamp the strap against the clamping face of the frame of the buckle as shown in Fig. 4.

From the foregoing it will be seen that the slotted side flanges of the frame provide means for supporting the clamping member so that such clamping member may move over the clamping surface of the frame in order to cause the rib 9 on the inner side of the slot in the clamping member to move toward and from the clamping surface, said slotted flanges also holding the rib 8 on the outer side of the slot in the clamping member close to the clamping surface of the frame when the clamping member is shifted to the inner ends of the slots to carry the rib 9 away from the clamping surface, thus preventing thebelt being passed under the clamping member without being passed through the slot. The projections on the clamping member provide wide bearing surfaces on the walls of the slots so that the wearing of said walls at any one point is prevented. At the same time, these projections serve as operating portions for the clamping member. The form of the slots in the flanges throws th clamping member to a position where the introduction of the strip through the slot in the clamping member is facilitated, while at the same time the passing of the strap under the outer edge of the clamping slide is prevented. It is apparent that the stronger the pull on the strap the greater will be the pressure of the clamping means upon said strap.

What I claim as my invention and desire to secure by Letters Patent is V 1. A belt buckle comprising a frame having a clamping surface, a clamping member having a slot through which the belt end is passed in order to pass between said clamping member and the clamping surface, and means for supporting said clamping member for movement over said clamping surface to cause a portion of the clamping member on one side of the slot to move toward and from the clamping surface'of the frame, and for holding a portion of the clamping member on the other side of the slot close to the surface when the member is shifted to carry the clamping portion thereof away from the clamping surface so as to prevent the belt end being passed under the clamping memher without being passed through the slot in the clamping member.

2. A belt buckle comprising a frame having a rear face forming a clamping surface and having also side flanges on opposite sides of said surface provided with slots, the

inner ends of which are arranged at a smaller angle to the clamping surface of the frame than the outer ends, and a clamping member having a slot through which the belt end is passed in order to pass between said clamping member and the clamping surface,

said clamping member having projections operating in the slots of the side flanges.

3. A belt buckle comprising a frame hav a face forming a clamping surface, and a clamping member having a slot through which t is belt end is passed in order to pass between said clamping member and the clamping surface, said clamping member being movable on the frame and having on opposite sides of the slot two ribs turned toward and operating over the clamping surface, the rib on the inner side being longer than that on the outer side and arranged to clamp the belt against the surface and the rib on the outer side being arranged to cooperate with the frame surface to prevent the belt being passed between said rib and the surface.

4-. it; belt buckle comprising a frame formed by a frontplate and laterally e1rtending side flanges, the surface of the plate between the flanges acting as a clamping surface, and a clamping member formed with a slot through which the belt is passed in order to pass between the clamping member and the frame, said clamping member being movably supported on the flanges so that upon tension on the belt, the portion of the belt between the clamping member and the frame will be held against movement and the clamping member on one side of the slot will cooperate with the clamping surface of the frame to prevent the passage of the belt between such clamp side and the clamping surface.
