1 Claim.
This invention relates to tools of metal construction adapted for general use and application, but especially designed for tools of the character employing ferrules, such as kitchen tools and the like.
It has for its object the provision of a tool construction which is capable of being manufactured at a reasonable cost and which will give long service under extraordinary service conditions It is a further object to produce a tool of the type specified by a method which is expensive, expedient and capable of mass production.
It is a particular object of this invention to provide an integral ferrule and tool shank or stem by a method which consists essentially in deforming a metal blank of commercially available stock.
With the above and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein:
Fig. l is an elevation of a kitchen spoon embodying the principles of this invention.
Fig. 2 is a central longitudinal section taken on lines 2-2 of Fig. 1.
Figs. 3, 4, 5 and 6, both inclusive, illustrate diagrammatically the steps and elements successively taken and utilized to carry out a ferrule extruding and cupping operation on a blank of commercially available stock.
Reference being had more particularly to the drawings B designates a relatively long round metal blank of the type usually available on the open market. The particular size, shape or length of the blank may, of course, be varied to suit the requirements of the tool to be finally produced without departing from the spirit of this invention. In practicing this invention, the blank B is preferably subjected to the action of forming tools I3 and M, as shown in Figs. 3 and 4. As a result of the action of these tools, the blank B is compressed lengthwise to extrude a thick integral collar H. The collar H is then subjected to a simultaneous compressing and cupping operation by a second set of tools l5 and I6, as shown in 5 Figs. 5 and 6, which compress the collar to form a flange and cup the flange in one operation, resulting in the formation of a socket or ferrule l2. The socket or ferrule thus produced is adapted to encase the end [3 of a handle, as shown in Fig. l, 10 whereby the handle end 13 is protected against spreading or splitting, if made of wood, or other damage.
The process of cupping the collar I I may be completed simultaneously with the collar ex- 15 truding operation whereby only one set of tools are necessary. Likewise, the ferrule forming or cupping process may be accomplished in any number of steps suitable to the design and construction of the ferrule being formed and the 20 shaping characteristics of the metal of the blank.
By providing a structure wherein the ferrule and tool shank are integral, the usual tendency of disengagement or loosening of the ferrule relative to the shank is completely obviated. 25
Furthermore, additional security in the connection of the handle body and the shank is provided by the present construction.
In addition, water cannot enter the ferrule through its connection with the shank where a 30 seamless union is provided as in the present invention. This prevents shrinkage of the handle by water soaking thereof and accordingly prolongs its serviceability.
What is claimed is: 35
The method of making a ferrule on a tool shank which consists in first compressing the shank to extrude a thick integral colar and then compressing said thick integral collar to form a cupshaped ferrule on said shank. 4Q
