BLANK FOR TABLE-KNIVES.

SPECIFICATION forming part of Letters Iatent No. 547,622, dated October 8, 1895.

Application filed April 10, 1895 To all whom it may concern.-

Be it known that I, THEODORE B.W1LooX. a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Table-Knives; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionrelates to an improvement in blanks for one-part hollowhandled tableknives, and particularly to the blank when it is in the form just prior to the final step in the process of manufacture. The object is to provide an inexpensive blank as a part to be used in a simple process of manufacture for this class of articles. I prefer that the blanks should be made from white metal throughout, but they maybe made of steel or other metal, if preferred.

My invention will be understood by reference to the accompanying drawings, in which Figure 1 shows in elevation a blank after it is passed through the first process of rolling. Fig. 2 is a plan of the same, illustrating how a single blank appears after having passed through two operations-namely, rolling and sawing. Fig. 3 is an end view of a die about to be applied to the handle of the blank, the latter being shown in section. Fig. 4 illustrates the appearance after the application of the die. Figs. 5, 6, 7, and 8 illustrate other dies and other steps in the process of manufacturing the knife-handle. Fig. 9 is an elevation of the completed knife, and Fig 10 is a section of the die used in giving the final shape to the knife.

The original blanks for these knives are in long strips, and the first process is to run them sidewise and flatwise through rollers to form the bolster, as shown at 2 2. The blanks appear at 1, and they have substantially the thickness of the handle, as shown at 3. The process of rolling flattens out the blade, as shown at 4, and builds up the bolster on opposite sides, as already mentioned. After the blanks are rolled a portion of the handle is Serial No. 545,169. (No model.)

sawed out by means of a circular saw, the out being preferably made from the top of the handle and having the form indicated in dotted lines in Fig. 1. The cut does not quite extend to the bolster at one end nor to the end of the handle at the other. After the sawing process the handle is placed in a die 5 6 and the body of it is pressed into the shape shown in Fig. 4. Another die 7 8 then forms the handle into the shape shown in Fig. 6, and then a die 9 10 brings it into the shape illustrated in Fig. 8. Itwill be understood that this shaping action takes place upon the central portion of the knife-handle, the end of the same being held by the die ends and finally shaped by the die 9 10 into the form shown in Fig. 9. The final step is accomplished by compressing the blank in the die 11 12, preferably in such a manner as to leave a burr when the edges of the hollow handle come together. When the burr is removed, a smooth hollow-handled one-part knife is at hand.

Instead of sawing out the metal of the handle it may be milled or stamped out, as will be readily understood.

Having now described my invention, I claim' 1. A blank for a one-part hollow handled knife, having a solid bolster at the forward end of the handle, a thinner portion for the blade, and a handle having a curved slit or cut extending nearly the whole length thereof and to a point beyond the center thereof, as and for the purpose set forth.

2. A blank for a onepart hollow handled knife, having a solid bolster at the forward end of the handle, a thinner portion for the blade, and a handle having a slit or out extending nearly the whole length thereof and beyond the center thereof, as and for the purpose set forth.

In testimony whereof I have signed my name, in the presence of two witnesses, this 9th day of April, A. D. 1895.

THEODORE B. WVILCOX.
