To all whom it may concern.-

Be it known that we, ALBERT LLOYD and WILLIAM FREDERICK GLYDoN, subjects of the Queen of Great Britain, residing at Birmingham, in the county of Vvarwick, England, manufacturers, have invented certain new and useful Improvements in the Manufacture or Production of Scissors and such like Cutting- 1 Instruments, (for which we have applied for Letters Patent in Great Britain, No. 1,121, dated 10th day of January, 1884,) of whichthe following is a specification.

Our invention has for its object the production or manufacture of scissors and such like cutting-instruments from metallic wire or rods of any suitable metal by the process or combination of steps,hereinafter described,whereby wrought scissors are produced in a simpler and more efficient manner than heretofore.

We will now describe the production of scissors from wire. We take wire of any suitable size and of sufficient length to form out of one piece both the blade and stem part, which latter is afterward bent into finger-bows-that is, a length of wire of uniform gage is bent near its middle, which afterward forms the shank or stem of one arm of a pair of scissors. The metal of the one side of the bend is next sub jected to the action of flattening or pressure dies in such a manner that the wire shall be at one part flattened out, while the other part is left plain or unoperated upon. The flattenedout part constitutes the blade or cutting part of the instrument, while the plain or other part so left forms the shank and metal to form-the bow of one half of a pair of scissors. Two such arms or levers, when crossing each other and jointed together near their middles,constitute a pair. of scissors.

We will now proceed to describe, with reference to the accompanying drawings, the manner in which our invention is to be performed.

Figure 1 represents a pair of scissors made according to the first part of our invention. Fig. 2 represents a piece of round wire or rod from which one of the arms or levers of the scissors, Fig. 1, is made. Figs. 3, 4, 5, and 6 wire, Fig. 2, passes in the production of onehalf of a pair of scissors, as represented in either Fig. 6 or 7.

In making a pair of scissors according to our invention, Fig. 1, we take a piece of wire ora rod of steel or of any suitable metal. (Shown at Fig. 2.) The said wire or rod is next bent at a, as shown in Fig. 3, which forms the shank of the scissor arm. The part a, extending from the bend a to the end thereof, is next subjected to the action of a pair of dies worked in a press or stamp in such a manner as to flatten out and shape the metal at that part so operated upon. The flattening and shaping described give the requisite form to the blade or cutting part of the scissors, as shown at b, Fig. 4. Fig. 4* represents the under side of the said Fig. 4, while Fig. 4 is a cross-section on the dotted lines, the blade I) being slightly twisted or concaved for giving the proper cutting to the edge. pierced with the rivet-hole c. We next bend up the end of the wire a into the finger bow or loop 11 Fig. 7 is an under side of Fig. 6. By now taking the two arms or levers, Figs. 6 and 7, and crossing and joining them together by a rivet through the rivet-hole c, the scissors, Fig. 1, is thereby produced.

\Vhen itis required that the finger bow or loop and the shank part of the arms of the scissors should be made lighter in metal than the blade part-that is to say, where a preponderance'of metal is required to be disposed in the blade part, while the shank or bow part partly-reduced diameter is marked d, which may be elliptical, circular, orany other suitable form in cross-section. The thick and reduced or shaped parts of the wire dd ,'Figs. 9, 10, 11, and 12, are subsequently operated upon for the bending, flattening, shaping, pierc- The blade b, Fig. 5, is next is required to be more slender-we proceed aslength only, as represented at Fig. 9. "The.

represent the various steps through which the I ing, and the bending up or shaping of the loop or finger-bow, as before described, thereby producing scissors with light shanks and slim finger-bows, as represented at Fig. 13. The blades are afterward properly ground and finished in any desired way, as shown in Fig. 14.

Having fully described our invention, and the manner in which the same is to be performed, we wish it to be understood that what we desire to claim, and secure by Letters Patent, is

1. The process for the manufacture of scissors from metallic wire or rods of uniform gage, consisting in taking a section of wire of uniform gage and of sufficient length and thickness, bending the section at the middle part to form the shank, then subjecting the metal at one side of this bend to the action of flattening or pressing dies to form the blade, and then bending the ends of the section to form the iinger-bows, substantially as set forth and shown. 2. In the manufacture of scissors from Wire or rods of uniform gage, the method consisting in first drawing a portion of the rod or Wire section to a diminished thickness or diameter to form the finger-bows and shank, then bending the metal at the middle part to form the shank, next subjecting the metal at one side of such bend to the action of pressure or flattening dies to form the blade, and finally bending the ends to form finger-bows, as shown and described.
