JoHN HAMPsoN, or oHILWoETH, ENGLAND, AssIGNoR To THIRD HAND PATENTS LIMITED, or LONDON,l ENGLAND.
To all whom it may 'concern Be ituknownV that I, JOHN HAMPSON, 4a subject of the King of England, residing at Tangley Mere, Chilworth, Surrey, England, v
have invented certain new and useful Improvements in Magnifying-Glasses, ofv which the following is a specification.
It is very often found inpractice that it is extremely diflicult to hold a magnifying glass or other optical instrument, owing to the fact that it is often desirable to have the ngers of both hands free'for manipulating the article jwhich it is required to view through the optical instrument, which with vthe usual construction of simple optical instrumentsis 'an impossibility, owing to the fact that' one of the hands or at least the thumb and one or more of thefngers of one ofthe hands have to be used for holding the instrument. y w
'My present invention relates to a method of' constructing optical instruments by` means of which the instrument or its parts may be 'carried .in any convenient position` while at the same time the hands are left perfectly free to holdv or vmanipulate the articlewhich is being exam-ined.,
The invention consists generally `in at` taching tothe frame of the lens or other optical instrument a spring clip-y or the like by means of which the instrumentvmay be clipped on to the thumb or one of the fingers or on to some .other part of the -p'erson`or to an article as required.
In one particular method of carrying-out my invention, I provide a spring clip'having curved'jaws of suitable size to embrace the thumb. This spring clip has attached to it a wire preferably'of soft metal such as copper, which wire carries at the opposite end the frame of a lens of any suitable description. vWhen utilizing lthis device it is simply necessary to spring the clip over the thumb'or finger of one of the handsand then to bend the wire so as t0 adjust the lens at the proper distance from the article to be viewed, when vthe thumb and all the lingers of the hand carrying the lens are perfectly free for manipulating the article. And in order that'my said inventionvmay bebetter- Specification of Letters Patent.

1 understood, I will now proceed to describe compa-nying this-specification in which :-l
Figurey 1 shows a side elevation of the device, Fig. 2 is a plan of same; Fig. 3 is a side elevation. Fig. 4 is a view illustrating -one application of the device.
the threading of a needle, the jaws?) of the clip a are opened and then the clip is sprung over the thumb of the'left hand. The strip g is brought into theproper position for viewing the eye ofthe needle. It will be ried in the. right hand to be threaded through the eye of the needle.
It will'be understood that devices of this description can be adapted for a great numngers free for holding or manipulating the articles to be viewed. For instance, they may be adapted for ophthalmic work, the ophthalmoscope being provided with a clip by means of which it can be attached to the hand -of the oculist, while his fingers eyes. The device may also be adapted for details in connection with stamps with great facility, while -having the lingers free for holding or manipulating the4 stamps.
For jewelers and lapidaries the device will be of eXtreme utility as it will enable them to manipulate small parts such. as screws and the like and polish and set stones with the greatest facility. For ene of copper wire is' then bent so that the lens the use of philatelists to enable them to eX-.l' amine perforations, water marks and otherthe same with reference to the .drawing ac- The same letters of'.reference are emfor instance at 1 Fig. 4, where it is being utilized to facilitate seen that it is quite easy for the thread car.
ber of uses, where it is desired to have the 1 are left perfectly free for manipulating the l tached by means of a series of rods whichv can telescope with respect to 'one another and be provided with suitable joints so that the Ulens can be brought in any required position with respect to the clip.
Other species of clips besides spring (clips as before described may be adapted to the device provided vit is a clip which can be quickly and easily attached over the finger, wrist, article of clothing or other object. y
` In some cases in place of using a simple lens compound or combination lenses may be used in connection with the optical in- A strument, and in other cases the lens or one or more of the lenses may be of smoked or colored glass for intercepting a' cert-ain yamount of light where it is required to shield the eyes from atoo brilliant illumination. Again, in other cases, the instrument may l lenses may be fitted to it, so that a lens of one power may be removed and replaced by be so constructed that various a lens of diiferent power to suit requirements. Y
What I claim and desire to secure by Letters Patent of the United .States of America 1s:-
1. The combination; of a magnifying glass, aclip consisting. of a pair of pivotally connected members having oppositely curved jaws for gripping a thumb below the joint,l a spring for holding. the jaws of said members in their gripping positions, means for opening the members, a lining on the inner sides of the jaws of the members, and an adjustable connection fixing t-he magnifying glass to the clip, substanV tially as described.
2. The combination of' a magnifying glass, a clip consisting of a pair of members, the members comprising loppositely curved jaws forming a clamp for gripping a thumb below' the joint and handles having lugs extending inwardly, a rod passing through said lugs and connected to the magnifying glass, and a spring on the rod between the lugs and havin its free ends engaging the handles ten ing to hold4 the jaws in their gripping positions, substantially as described.
In testimony whereof I aiiiX my signature in presence of two witnesses.
