t Application December 2, 1946, Serial No. 713,552]
This invention relates to. improvements in scissors.
An object of the invention is to provide an improved spring operated self-opening scissors.
Another object of the invention is to provide an improved spring operated self-opening scissors which will include a one-piece combined handle section, finger receiving ring and cutting blade, and a similarly formed and shaped combined handle section and finger receiving ring disposed on said first mentioned handle section and finger engaging ring and suitably attached thereto by welding or brazing, and a second cutting blade pivotally mounted upon said first mentioned cutting blade, together with a tensioning spring supported at one end between said handle sections and having a slidable engagement with the irmer end of said pivotally mounted cutting blade.
A further object of the invention is to provide an improved scissors construction which will include handle and finger receiving portions, a fixed cutting blade and a pivoted cutting blade, together with spring means for opening and normally holding the pivoted blade in open position, whereby the scissors may be grasped with the forefinger engaging the back edge of the fixed cutting blade, the second finger in the arcuate seat in front of the ring, the third finger extending through the ring, the little finger in the arcuate seat at the opposite side of the ring, and the thumb engaging the back of the pivoted cutting blade, and operated by repeatedly moving the thumb and fingers toward each other.
Another object of the invention is to provide an improved form of automatic self-opening scissors which will be highly efficient in use, and
relatively inexpensive to manufacture and produce.
Other objects will appear as the description proceeds.
In the accompanying drawings which form a part of this application,
Figure 1 is a plan view of the improved scissors shown completely assembled;
Figure 2 is a plan view of the integral handle, finger receiving ring and cutting blade;
Figure 3 is a plan view of the cooperating similarly formed integral handle and finger receiving ring;
Figure 4 is a plan view of the cooperating pivotally supported cutting blade;
Figure 5 is a plan view of the spring which is used for automatically openin the pivoted cutting blade, and
waits. r-30 m Figure '6 is a sectional view taken on the line 6-6 of Figure 1.
Like characters of reference are use throughout the following specification and the accompanying drawings to designate corresponding parts.
In carrying out the invention, there is provided an improved form of automatic self-opening scissors including an integrally formed handle portion or section I, a finger receiving ring 2, and a cutting blade 3. A shallow bore or socket 4 is formed in the inner surface of the handle portion i adjacent its end, and is adapted to receive the right angularly bent inner end 5 of the spring 6, whose purpose and operation will be hereinafter described in detail.
A cooperating handle portion or section i and finger receiving ring 8 of a similar size as the handle portion or section I and finger receiving ring 2 is provided, and is formed with an inwardly extending slot having parallel side walls 9 at its inner end and an outwardly flared wall Ill at its outer end, said slot being adapted to receive and house the pivoted blade actuating spring 6. The slot is widened at its outermost end to form the spaced oppositely disposed stop shoulders H and I2 for engagement with and limiting the side motion of the stop shoulders l3 and l 4 formed on the inner end of the pivoted cutting blade l5 which is pivotally mounted on the pivot screw it extending into the stationary cutting blade 3 for shearing or cutting purposes when used therewith.
A slot i1 is formed in the inner end of the pivoted cutter blade l5, and is adapted for slidably receiving the outer end of the blade opening and actuating spring 6. From the foregoing description, it will be seen that the scissors may be readily and naturally supported with the forefinger engaging the back edge of the fixed cutting blade, the second finger in the arcuate seat, in front of the ring, the third finger extending through the ring, the little finger in the arcuate seat l8 at the opposite side of the ring, and the thumb engaging the back of the pivoted cutting blade l5, and operated by repeatedly moving the thumb and fingers toward each other.
As clearly illustrated in Figure 6 of the drawings, the handle portions I and I and the finger receiving rings2 and 8 may be secured together along their marginal edges by means of the welding or brazing 19.
While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.
Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:
1. A scissors including an integral handle portion, a finger receiving ring and a stationary cutting blade, a pivoted cutting blade on said stationary cutting blade, said handle portion being formed with a slot having outwardly flared side walls, the ends of said walls being counterbored to form lateral stop shoulders, a resilient spring disposed in said slot anchored at its inner end and having slidable engagement with said 'pivoted cutting blade for normally holding the same in open position, and stop shoulders on the inner end of said pivoted cutting blade received within the inner periphery of said counterbored walls for 20 1,186,235
