Application filed March 9, 1915.

To all whom it may concern:

Be it known that 1, G12 ion H. DAY, a citizen of the United States, residing at Southbridge, in the county of Viforcester and State of Massachusetts, have invented certain new and useful Improvements in Lens- Franies, of which the following is a specification. p

This invention relates to frames, more particularly to a frame of improved construction which is adapted to serve as a combined lens supporting means and handle for reading glasses. 7 p

An object of he invention-is to construct the frame from a single strand of resilient wire to include a lens gripping portion and a handle, thus materially decreasing the cost of manufacture of the same.

Another object is to provide a frame of this character which requires but one soldering operation after the wire has been bent to the desired shape.

A further object .is to so construct the frame as to greatly facilitate the operation of applying or disengaging the lens from the frame.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and claimed.

In the drawings:

Figure I is a top plan view ofa lens frame constructed in accordance with the invention, showing the lens secured therein.

Fig. 11 is a view similar to Fig. I showing the manner of bending the frame before the free end of the handle is secured to the lens gripping portion.

Fig. 111 is a detail sectional view on the line IIITII of Fig. I.

Fig. IV is a plan view of a handle portion of a slightly modified form of construction.

Fig. V is a detail View, showing the manner in which the free end'of the lens gripping portion might be associated with the adjacent portion of the frame.

Referring to the drawings by numerals, "1 designates a single strand of resilient wire which is reduced and flattened throughout a portion of the length thereof to provide a light, flexible, and neatly appearing lens clamping portion 2, a V-shaped groove 3 being formed in one face of said flattened Specification of Letters Patent.

portion to receive the correspondingly shaped peripheral edge d of the lens 5.

The lens herein shown is circular in shape, and the flattened clamping portion of the wire is of a length to entirely embrace the same, the larger portion of the wire being extended from the clamping portion as at 6, doubled upon itself as at 7, and having" the free' end thereof extending inwardly as at 8, to form a handle.

In order to provide a'frame which will firmly clamp the lens therein and prevent accidental disengagement of the same, the lens gripping portion is bent to a size slightly smaller than the lens which it is adapted to receive, so that when the lens is positioned therein the inherent resiliency of the wire will cause the lens to be firmly secured in place.

The handle portion of the frame may be utilized to further increase the clamping action of the clamping portion. It will be noted, as disclosed in Fig. II of the drauings, that the free end 8 of thehandle is bent to lie in close-proximity with the portion 6. The terminal of this free end is adapted to be swung outwardly slightly against the spring action of the loop 7 and secured as at 9, by soldering or in any other suitable manner, to the gripping portion 2, it being apparent that the resiliency of the handle is added to that of the gripping portion.

By reference to the drawings it will be noted that the portions 6 and 8 of the handle converge inwardly toward the gripping portion from the loop 7 It will be obvious that disengagement of the lens from the gripping-portions may be facilitated by inserting any suitable instrument between the portions 6 and S of the handle adjacent the loop 7 and forcing the same toward the lens, the lens gripping portion being thus sprung from engagement with the lens.

In Fig. IV of the drawings a slightly modified form of handle is shown. In this form the arms of the handle are crossed, the advantage gained residing in the fact that the outer portion of the handle may be gripped and sprung together to disengage a lens from the gripping portion, the construction otherwise remaining the same.

If desired, the free end of the lens gripping portion 2 may be inserted within the recess 10 formed in the adjacent portion of the frame, as disclosed in Fig. V of the drawings, this construction providing a firm gripping action at the terminal ends of the said grippingportion.

From the foregoing description taken in connection with the accompanying drawings, it is thought that the construction and operation of the device will be clearly understood, and while I have herein shown and described but one specific form of my invention, I do not Wish to; be limited thereto, except as to such limitations as the claims may import.

I claim:

1. In a device of the character described, thecombination with a lens, of a one-piece frame and handle therefor, comprising a grooved portion adaptedto extend circumferentially of and retain the lens in position, and a handle portion integral with one end of the lens frame thus formed, said handle being shaped in a spring loop and having its opposite end secured to the end of the frame but spaced from the free end, the resiliency of the looped handle tending to decrease the size of the space inclosed by the lens frame whereby the spring of the handle serves to resiliently secure the lens in position Within its frame, substantially as de scribed. V

2. Acne-piece magnifier frame and handle, comprising a grooved annular member in the form of a substantially closed ring adapted to receive a lens, and a handle integralwith one end of the ring and formed Copies of this patent may be obtained for into a spring loop united with the opposite a or free end of the ring a distance from the ceived therein, whereby the lens may be inserted in its frame by separation of the ends of the spring looped handle member, While releasing of the handle member will cause it to spring inward and grippingly secure the lens Within the frame, substantially as illustrated.

8. In a magnifier, the combination with av lens, of a rim encircling and resiliently engaging the lens, and a spring looped handle integral with one end of the lens rim and bent outward substantially at right angles thereto and extending reversely inwardly and attached to the free end of the rim at a distance from the end thereof, the integral point of merger of the handle and rim having a socket formed therein adapted to receive the free terminus of the rim as in wardly actuated by the resiliency of the handle, whereby the'completed structure possesses a smooth and.uninterrupted rim from which the lens may be removed by forcing apart of the ends of the looped handle member, substantially as illustrated.

In testimony whereof I afiix my signature in presence of two witnesses.
