3 Claims. (CI. 88-39) My invention relates to a magnifying device adapted to be mounted upon a flashlight, or the like.

An important object of the invention is to provide a device of the above-mentioned character, which maybe quickly and conveniently applied to and removed from a flashlight, or the like, and having its parts foldable when detached from the flashlight, sothat the entire device may be conveniently carried in the pocket.

.6. further object of the invention is to provide means whereby a portion of the device has frictional engagement with the barrel of the flashlight, whereby the glass-carrying frame may be properly held at thedesired angular adjusted position. A further object of the invention is to provide a device of the above-mentioned character, which is simple in construction andinexpensive to 2 manufacture. i

Other objects and advantages of the invention will be apparent during the course of the following descriptlon.

In the accompanying drawing, forming a part of this specification, and in? which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of the device embodying my invention, showing the same applied to the barrel of a flashlight,

' Figure 2 is a side elevation of the same,

, Figure 3 is a horizontal section taken on line 33 of-Figure 1, v

Figure 4 is a side elevation of the device, showing the parts collapsed,

Figure 5 is an edge elevation of the device embodying a modified form of the invention, showing the same applied-to the barrel of a flashlight, and

Figure 6 is a side elevation of the same.

In the drawing, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral 10 designates the barrel of a flashlight, of any well known or preferred type. having the usual lens 11, at its forward end.

As shown in Figures 1 to 4, inclusive, the mag-.

nifying device embodies a ring or frame 12, carrying a magnifying glass 13. This frame '12 has a coupling ring 14, rigidly attached thereto.

The numeral 15 designates a split resilient clip, which is adapted to be 'spnmg upon the barrel 10. This spring clip is provided between its ends, with a'longitudinal slot 16, slidably receiving the coupling ring 14. I

As clearly shown in Figure l, the spring clip 15 is applied to the barrel 10, and the coupling ring 14 will have its periphery engaging the barrel 10. Since the coupling ring 14 is slidable within a slot 16, this coupling ring has a pivotal or rolling connection with the spring clip 15..

This enables the frame 12 to be angular-1y adjusted with respect to the barrel, and the frame will remain in the selectedadjusted position, by virtue of the engagement of the ring 14 with the barrel 10, the spring clip 15 serving to hold the coupling ring in proper frictional engagement with the barrel 10. By the usual operation of the flashlight, the light may be projected upon the object, which may be viewed through the magnifying glass 13, the frame 12 being adjusted to the proper angular position.

1 When the clip 15 is removed from the barrel 10, the frame 12 may be swung into the resilient clip, which is expanded suitably for this purpose.

In Figures 5 and 6, I have'shown a modified form of the invention. In these figures, the

- frame 12; carrying the. glass 13, is provided witha radial shank 17, rigidly attached thereto,'and

this shank is pivotally connected with a radial extension 18, by means of a pivotal element or pin 19. The radial extension is carried by a split resilient clip 20, which is adapted to be sprung upon the barrel 10, as clearly illustrated in Figure 5. The shank 17 extends inwardly beyond its pivot 19, and inwardly beyond the inner periphery of the curved clip 20, and has a curved face 21,

directly engaging with the barrel 10. This engagement affords a proper frictional engagement between the shank 17 and the barrel 10, whereby the frame 12 will be held in the selected angular adjusted position. When the clip 20 is removed from the barrel 10, the frame 12 may be swung'yinto the clip, the clip being sprung to an open position to permit of the insertion of the frame therein. The clip will have sufficient frictional engagement with the frame 12, so that the collapsed parts will be held together and thedevice may be conveniently carried in the pocket. or the like.

It is to-be understood that the forms of my invention herewith shown and described, are to be taken as preferred examples of the same, and

that various changes in the shape, size and arrangementof parts may be resorted to without departing from the spirit .of the invention or the scope of the subjoined claims.

Having fully described my invention, what I claim is:-

1. A split curved resilient clamp to be mounted .upon a rigid support, an object holder, and' a mer ovahly secured to the oloject holder and pivot connected with the clamp in a w. .i w

ner to s in n pl at substantially a right to the plane of the cl the arrangebe such that the holder y he shifted u: into the clamp and held therein by frictional engagement, the member projecting inwardly beyond the inner surface of the'clamp to frictionally engage the surface of the rigid support so t the holder may he moved to selected or positions and held in such positions. 2. A split curved resilient clamp to he mounted upon a rigid support and having an elongated slot i -l ill thereof, an object holder, and a ring rigid] secured to the object holder and slidahly mounted Within the slot, said m: being of such a shape in cross-section that it will not perceptibly tilt laterally within the slot, the inner portion of the ring projecting inrrar heyond the er surface oil the clamp ment to the object holder and arr for engagement with the rigid support so that the ring r-rmn hold the object holder in selec usted positions, the r: ngernent heing such that the holder at be shifted TM 11.; into the clp and held therein by frictional engagement. 3. A spilt curved resilient clamp provided at one end with a generally ra w the clp being adapted to he mounted upon a rigid support, an object holder, a z rigidly secured t ed upon the inner side of the generally radial ll ment extending through the .1.
