- Application filed January 1a, 1908. Serial No. 410,485.

geles, in the county of Los Angelesand State of California, have'invented new and useful Improvements in Magnifyi 1g Glasses, of

whlch the following is a speci tion.

This invention relates particularly to a novel form of .mounting for a lens whereby I am enabled to make a combination of two lenses without increasing the size of the complete mounting beyond what is usually employed for one lens.

To this end my invention consists of a combination with an ordinary pocket magnifying' glass of amounting for a high power lens within the pivot of the usual or low power lens so that the space ordinarily utillzed by the pivot may e occupied by the high power lens.

accomplish the above by means of the device described-herein and illustrated in the accompanying drawings in which:

F gure 1,1s a perspective view of mymagnifying glass in its open position. Fig] I2,is. a longitudinal section of the same.

Referring to the drawings 5 designates a magnifying, lass case of the construction usually em oyed for pocket glasses and which may. -e provided with a compass 6 and a securing ring 7 or any other attachment which may be-desired.

. At the end of case 5 o posite ring 7 abearing sleeve 8 is mounted between the two side members 9 and 10 of case 5. Upon this bearing sleeve a frame 11 is rotatively mounted, according to the usual construction, and this frame carries a lens 12 which is of comparatively low power.

- Sleeve 8 is provided on itslower end with a shoulder 13 upon which a high power lens 14 rests, the lens being laced within the sleeve with its upper en rojecting above the same. This high power ens is preferably of the pyramidal form shownalthough it ma be of any other configuration which len s itself to placement inside of sleeve 8. A bushing 15 is adapted to fit tightly-within sleeve 8 and is provided with an internal bore 16 which is contracted at its end to form a circular shoulder 17 which bears against the upper end of lens 14 and holes the same rigidly in position. Bushing 15 is adapted to remain in place by being tightly fitted but it may be cemented in or secured in any other manner which is deemed desirable.

From the foregoing description it will be observed that my novel form of mounting enses in one instrument without increasing the size of thecase in which they are mounted. This is on account of the fact that sleeve 8 or the equivalent bearing for frame .11 must be of sufiicient size to prevent the frame from becoming loose thereon and to insure an even rotation of the frame. I have utilized this space which is usually un-v necessarily occupied by the bearing and therefore do not increase the size of the magnifying glass as a Whole.

Having described my invention what I claim as new and de'sire to secure by Letters Patent is 1. A device of the class described, comprising a pivotally mounted lens, and a second lens mounted within the pivot of said first named lens.

2. A magnifying glass comprising a case, .a hollow pivot mounted in said case, a-lens mounted on saidpivot, a lens within said ermits the combination of two magnifying pivot, and a bushing adapted to fit within said, pivot and over "said lens.

, 3. A magnifying glass comprising a case, a sleeve mounted wlthin said case, a frame rotatively mounted on said sleeve, a lens mounted in said frame, -a lens within said sleeve, and a bushing adapted to fitover said lens and hold the. same in said sleeve.

In witness that I claim the.foregoing I have hereunto subscribed my name this 4th day of January, 1908.

FRED BOLD.
