Application filed March 21, 1916. Serial No. 85,693.
To all whom it may concern:
Be it'known that I, Funnels HENRY CAL- LAHAN, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Magnifying Attachments for Scissors, of which the following is a specification.
This invention relates generally to a supporting means for lenses and particularly to a magnifying attachment especially adapted for use in connection with a pair of scissors, and which consists in the novel features hereinafter described and claimed.
An object of the invention is to provide a magnifying attachment consisting of a frame and a glass, the said frame being applicable to the pivot of the scissors and adapted to be swung to position the glass beyond the edges of the blades of the scissors. A prop is pivotally attached to one of the handle portions of the scissors and may be used for supporting the scissors in an inclined position when the magnifying attachment is in use.
Another object is to provide an attachment of this character having means for securing it in closed inoperative position on its support to prevent its accidental opening.
In the accompanying drawing Figure 1 is a perspective view of a pair of scissors with the magnifying attachment applied.
Fig. 2 is a side elevation of a portion of the same.
Fig. 3 is a transverse sectional view of the same cut on the line 3-3 of Fig. 2.
Fig. 4c is a transverse sectional view of the same cut on the line H of Fig. 1.
Fig. 5 is a transverse sectional view of the same cut on the line 5-5 of Fig. 2.
As illustrated in the accompanying drawing, the scissors includes handles 1 of usual pattern and blades 2 which are pivotally connected together by means of a pivot bolt 3 in the usual manner. A spring washer 4 is mounted upon the bolt 3 and is held in position thereon by means of a nut 5 which is screwthreaded upon the said bolt.
The magnifying attachment comprises a frame 6 which is provided with a radially extending attaching shank 7 having an eye 7 which receives the pivot bolt 3. A lug 8 extends radially from the frame 6 at a point diametrically opposite that side at which the eye 7 is located and the said lug 8 projects laterally beyond the face of the frame '6 which is designed to be arranged adjacent its support and is adapted to engage between the handles 1 of the scissors whereby the said frame is held in a folded position with relation to the scissors and prevent it from accidentally swinging open. A lens 9 is carried by the frame 6 and when the device is in use as a magnifying glass a needle and thread may be observed through the lens in order to facilitate the threading of the needle. A prop 10 is pivotally connected with one of the handles 1 and may be used for supporting the scissors in an inclined position while the magnifying attachment is being used for assisting the sight of an operator while threading a needle. When it is desired to use the scissors for shearing or cutting the prop 10 is folded in close proximity to that handle 1 with which it is pivotally connected and the frame 6 is swung upon the pivot bolt 3 so that the lug 8 of the said frame lies between the inner sides of the handle 1.
From the foregoing description taken in conjunction with the accompanying drawing it will be seen that an attachment of simple and durable structural arrangement is provided for a pair of scissors and that the same may be conveniently used for assisting the sight during the operation of threading a needle.
lVhile the attachment is especially adapted for use in connection with a pair of scissors, it is to be understood that it is equally applicable to a foldable supporting member of any construction, so long as such member consists of a pair of pivotally connected legs to which the prop is to be attached, said legs being designed to take the place of the handles and blades of the scissors.
Various other changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit of this invention, and hence I do not wish to be limited to the construetion herein shown and described other than that set forth in the appended claim.
Having described the invention what is claimed is The combination with a pair of scissors having blades connected by a pivot and handles spaced laterally at the rear of said pivot; of a lenscarrying frame mounted on said pivot to swing laterally relative to said scissors in a plane parallel with the path of swinging movement of said blades, and a prop pivoted at one end to the inner end of one of said handles on the inner face thereof and adapted to swing between said handles when in closed inoperative position, said prop being mounted to swing in a plane at an angle to the path of swinging movement of said blades to form a lens supporting tripod in connection with said blades 16 when the scissors are open and the prop swung outward.
In testimony whereof I, affix my signa ture in presence of two witnesses.
FRANCIS HENRY CALLAHAN. Witnesses:
