The present invention relates to buckles and method of making the same and is more Y particularly directed toward the provision of an improved form of hook fora cast metal buckle.

' The present invention contemplates the manufacture of cast buckles in such a manner that the hook for the ,buckle'may be formed at the same timeas the cast buckle body. In

carrying out the present process of manufacture, bronze molds are employed. These molds are provided with suitable mold cavities to form the buckle body and are arranged to receive a metal rod, or bar, forming the axle of the hook. The hook itself is cast onto the metal rod at the same time as the buckle body is cast, and the ends of the rod, or bar, are anchored in suitable lugs in the-body.

i The accompanying drawings show a form 20 of mold suitable for making buckles of the present typetogether with a'form of buckle made in such molds, and the various steps in the operation of making such a buckle.

In these drawings:

Figure 1 is a perspective view of a two cavity mold illustrating one cavity empty and the other cavity filled with a completely cast Figure 2 is a perspective view of the buckle after having been removed from the mold;

Figure 3 is a side elevational view of the buckle as taken from the mold, and illustrating in dotted and in dot and dash lines the position of the buckle hook during its formation; and

Figure 4 is a front elevational view of a complete buckle. x

The buckle, as shown in Figures 2, 3 and 4, has a body 10v of suitable ornamentation, shape and figuration. This buckle body may be cast out of bendable white metal alloy. The hook of the completed buckle is indicated at 11. It is made of the same metal as the buckle body and is carried on an anchorage portion 12, cast about a metal rod 13. This rod is preferably a small brass pin. The ends of the pin extend into lugs 14 and 15, cast integral with the buckle body.

For manufacturing these buckles one may employ a mold such as indicated in Figure 1. The lower mold part has two buckle formlng cavities 21 of the design and con- ,figuration of the buckle to be produced. It will be understood that one-half only of the cavltyis indicated in the upper rear part of the figure, and that only one-half of the finished buckle is indicated in the lower front part of the figure. 'An angle shaped mold member 22 is carried on top of the bottom part 20 and is held in a definite position by ,pins 23. The under face 24 of this mold part 22 is smooth. 1 The inner face 25 is cut. away,

as indicated at 26 and 27 ,to form one-half of' the lugs '14 and 15. The upper face of the mold part 20 and the inner face 25 of the mold part 22 are cut away, as indicated at 27 and 28, to receive the metal pin 13. These mold parts are also cut away, as indicated at 29,

to form a cavity corresponding with the anchorage portion 12 of the hook. A third mold part 30, is generally similar to the mold part 22 and is held in definite position by pins en- 7 tering holes 31.

' The mold parts 22 and '30 are cut away, as indicated at 32, to form a filling hole and their adjacent faces are grooved,as indicated at 33, 34 and 35, to form gates 33, 34' and 35'.

' The grooves 33 and 35 extend down toward the cavities 261and 27, while the groove 34 extend down to a hook forming cavity 36. The lower end of this hook forming cavity opens into the anchorage cavity 29. A gate 36' also extends to this anchorage cavity.

After the metal rod 13 has been set in its place, the mold parts are secured together and metalis poured into the filling spout 32, flowing down through the various passages and filling all the cavities. .It simultaneously forms the buckle body 10, the anchorage portion 12and the hook forming portion 11, as well as filling the gates with metal.

After the molds have. cooled, the part is removed and then the mold part 22, together with the castings, are. removed from the mold part 20. The moldpart 22 may then be separated from the castings. It will be noted from the right hand side of Figure 1 that the gates are constricted as indicated at 37 38, 39 and 40.

One may grasp the buckle body in one hand luu and the gates in the other and bend and twist the casting so as to break the gates away from the buckle body and hook. This will leave the casting in the condition shown in Figures 2 and 3. The entire buckle body, hook, anchorage portion, and pintle, w1ll be a completed unit. Gentle pressure may then be applied to the cast metal 12 ,about the pin, so as to break the ends of the pin away. from the cast metal which envelops them, permitting turning of the pin and parts carried thereby. The hook llmay then be bent trative of the type of device which may be produced by the present process. It will also be apparent that this process of manufacture eliminates many expensive operations heretofore necessary in the construction of ornamental buckles out of low melting po1nt alloys.

What is claimed is: r 1. The method of making buckles which consists in simultaneously casting a buckle,

body of low melting point metal forming integral cast lugs about a (pivot bar of higher melting point metal, an casting a buckle tongue with an anchorage-portion about the pivot bar between the lugs. I

2. The method of making buckleswhich consists in casting a buckle securing member with an integral anchorage about the middle portion of a bar of higher melting point metal, and casting a buckle body with lugs enveloping the ends of the bar.

3. The method of making buckles which consists in casting a buckle securing member with an integral anchorage about the middle portion of a bar of higher melting point metal, casting a buckle body with lugs e11- veloping the ends of the bar, and applying twisting effort to the anchorage to loosen the ends of the bar from the lugs so that the bar and securing member may be turned with the ends of the bar acting as pintles.

4. The method of making buckles which consists in casting a bendable hook member with an integral anchorage about the middleportion of a bar of higher melting point metal, and casting a buckle body with-an ornamental face and re'arwardly extending lugs enveloping the ends of the bar, applying twisting effort to the anchorage to loosen the ends of the bar from the lugs so that the bar and hook member may be turned with the ends of the bar acting as pintles, bending the hook member to permit passing it through the'opening in the buckle body to place the hook member in front of the buckle body, and straightening out the member to the shape of a buckle hook.

5. In the method of making buckles where.- in the buckle body is cast about a pivot pin,

the steps which comprise loosening'the ends gral cast lugs on said body, said bar being of higher melting point metal than that of said body. simultaneously casting a buckle tongue with an anchorage portion about the pivot bar betweenthe lugs, removing the casting from the mold and applying twisting effort to the said anchorage portion to render the said tongue pivotally movable.

7. The method of making buckles which comprises inserting a metal pivot forming bar in a mold, casting in said mold and about the metal pivot bar a metal buckle body having lugs integral therewith for holding said pivot bar between the lugs, said bar being of higher melting point metal than that of said body, simultaneously casting a buckle tongue 0 with an anchorage portion about the pivot bar between the lugs, removing the casting from the mold and applying twisting effort to said anchorage portlon to render the said tongue pivotally movable.

8. The method of making buckles which comprises inserting a metal pivot forming bar ina mold, casting in a single operation in said mold and'about the metal pivot forming bar a buckle'body having integral lugs and a buckle securing member, said pivot bar being held between said lugs and being of higher melting point metal than that of said body, said securing member having an anchorage portion about the pivot bar between the lugs, removing the casting from the mold and applying twisting effort to said anchorage portion to render said member pivotally
