Specification of Letters Patent.
Patented Mar. 8, 1921.
Application filed. March 16, 1920. Serial No. 866,330.
To all whom it may concern Be it known that I, JOHN FREDERICK NEW- TON, a subject of the Kin of Great Britain and Ireland, residing at heflield, England, have invented certain new and useful Improvements in or Relating to Folding Sc1ssors, of which the following is a specification, reference being had to the accompanying drawing.
This invention relates to folding SClSSOI'S of the kind in which the bows or handle portions of the scissors are pivoted to the shanks of the blades, and fold over toward the fiat sides of the blades. The object of this invention is to provide an improved construction of scissors of the kind.
In scissors of the kind hitherto constructed the shanks of the blades have been pivotally mounted in openings in the bow handles, the bows forming the springs which keep the parts in the open or closed positions.
According to this invention, the bows are formed with solid shanks and the springs are formed either in or on the shanks of the bows to co-act with the shanks of the blades or the springs are formed in or on the shanks of the blades to co-act with the shanks of the bows.
The preferred form of the invention is illustrated in the accompanying drawings in which Figure 1, is a plan of a pair 0 scissors embodying the improved construction and in the open position; Fig. 2 is an edge view of the pair of scissors shown in Fig. 1 when partly closed; Fig. 3 shows the said scissors folded; Fig. 4. shows a blank from which the bow ortion is formed.
Referring to the rawings the blades 1 are pivoted together in the usual manner of scissors each blade having a short shank or extension 2 which follows the usual direction of the handle or bows.
The bows 3 have the ordinary thumb and finger holes and are provided with flat shanks or extensions 4, the extreme end of each shank 4 having upturned edges 5 between which edges the shank 2 of the blade is pivotally hinged by a rivet passing through it and the upturned edges.
with t to the blade of a pocket knife. But the invention is not restricted to this form as the spring tongue may be formed equally well by slitting the blade shank to engage e shank on the bow; also the spring tongue may be formed separately, if desired, and may be attached either to the bow or to the blade shank.
The arrangement described insures the blades opening when the bows are moved away from one another but should the scissors open when in the pocket, a bow always protects the point of a blade.
The bows may be made of any suitable metal, such as nickel silver and the invention is applicable to scissors having different shaped blades, for instance, to manicure scissors having curved blades, in which case the bows would also be correspondingly curved.
Folding scissors, comprising a pair of pivotally connected blades each having a shank portion, a pair of bows each provided with a shank pivotally connected to one of the blade shanks to permit said bows to be folded on either of the fiat sides of the blades, the bow pivots being at right angles to the blade pivot, each of said bows having a central longitudinally extending spring tongue integral with the shank thereof and adapted to engage the shank of its blade thereby to retain the bows in either folded or unfolded position.
In witness whereof I have hereunto set my hand in presence of two witnesses.
JOHN FREDERICK NEWTON.
