METHOD OF MAKING WROUGHT-METAL HOOKS.

SPECIFICATION forming part of Letters Patent No. 624,067, dated May 2, 1899. Application filed Augu t 24, 189 7. Serial No. 649.340. (No model.) I

To all whom it may concern:

Be it known that I, FRANK J. MONZ, a citizen of the United States, and a resident of the city of New Haven, county of New Haven, and State of Connecticut, have invented a new and useful Improvement in \Vrought- Metal Hooks, fully described and set forth in the following specification, taken in connection with the accompanying drawings, in which like letters of reference represent like parts in all the figures.

Figure 1 is a side elevation of the blank from which the hook is formed; Fig. 2, the same partially operated upon; Fig. 8, a detail view of the plate to which the hook is secured, and Fig. 4 a side elevation of the hook as finally formed and assembled.

This invention consists in a novel and efficient method of constructing hooks, more particularly that class of hooks wherein a plate for securing the hook to a shelf or other article is formed separate from the hook and united thereto by rivets, screws, or other means. In this class of hooks an extra amount of metal is required at the angle of the blank to form the rivets and other portions of the hook proper where it is attached to the plate. It has been usual in forming hooks of this description to draw or taper the blank or rod prior to bending and flattening the same to shape in such a way that the rod will be of greater thickness at one portion than at another, so that at the thickened portion there will be enough metal to v be subsequently formed into the studs, rivets, 850., for attaching the hook to the plate. The present invention obviates the necessity of such previous drawing or tapering by obtaining the necessary amount of metal for the studs or rivets from an increased length of the wire instead of from an increased thickness, and to this end when the angle of the blank is formed it is so arranged that the length of the Wire included therein will be greater than the length of the corresponding portion of the finished product between the same points on the blank.

A represents a wrought-metal hook formed from a blank, as shown in Fig. 1, bent up to form an angle a, the blank being throughout of equal diameter except where the heads other means he provided for fastening the plate C and hookA together. This is accomplished by swaging the blank A (shown in Fig. 1) in a press, so that the metal in the angle (t is forced to assume the form shown in Fig. 2, wherein a vertical semicylindrical portion B unites the upper and lower arms I) and D of the hook and has on its flat side two laterally-projecting studs 1'), corresponding to the perforations c on the plate 0. As the portion B is of greater diameter when taken through the studs b than the arm D and D, the extra metal necessary for its formation is obtained by constructing the angle a, Fig. 1, of such depth that although it is of equal diameter with the rest of the shank there will be sufficient metal between the points 00 and 00 to form, upon pressure, the portion 13 and studs 1). The arms D and D are held by proper mechanism against longitudinal movement, and pressure is exerted at the apex of the angle to reduce the length of the angle portion of the rod, and thereby crowd the metal on either side between the apex and the rigidly-held arms to greater width, which widened portion is formed into the semicylindrical portion B, with the lateral studs 19 on the flat side thereof. By this means a blank of uniform thickness may be utilized to form the hook and the necessity of drawing the blank to different diameters obviated. The arms D and D may be subsequently curved, as shown in Fig. 4, and the hook and plate assembled by inserting the studs 5 in the perforations c and riveting them down to secure the plate to the hook.

Having now described my invention, what I claim, and desire to secure by Letters Patcut, is-

The herein-described method of making a wrought-metal hook, consisting of bending shank being greater than its length in the of said studsaplate for attaching the hook to [O finished article; reducing the length of the thedesired article,substantially as described.
