MAGNIIYIN'G AND ILLUMINATI IING DEVICE.

Application filed ma 31, 1927. Serial No. 195,573.

The present invention pertains to a novel magnifyin and illuminating device adapted especial y for medical and police exannnations and similar urposes where it may be desired to magni the illuminated area. The principal object of the invention is the provision of a device of this character which is simple and compact and may conveniently be carried on the rson of the user in the manner of a poo et flash light. The device comprises essentially a lamp socket havin a handle at one end and areflector and s ield at the other end for overlying a lamp inserted in the socket. To the shield is pivoted a air of magnifying lens holders which ma e positioned forwardly of the lamp. en the light is focused on an object under examination, the shield obstructs the light from the eyes of the user, and one or both of the lens holders may be brought into the line of sight to the area under examination. v

The invention is fully disclosed by way of example in the following description and in the accompanying drawlng, in which Figure 1 is a plan view of the device;

Fig. 2 is a side elevation thereof partly in section;

Fig. 3 is a detail elevation showing the shield and the lens holders; and

Fig. 4 is a section on the line 4-4 of Figure Reference to these views will now be made by use of like characters which are employed totdesignate corresponding parts throughou The device includes a lamp socket 1 hav-' ing at one end an integral handle 2 and at the other end a shield and reflector 3 dismade and broken by a screw switch 7 mounted in the socket.

The forward edge of the shield 3 is formed with a curved stop member 8, and adjacent this member is an ear 9. The ear serves as a pivotal support for a pair of lens frames or

holders

10 and 11 each having an ear 12 in alignment with the ear 9. A spacing washer 13 is positioned hetweenthe ears 12,

and the aligned parts are penetrated by a pivot pin 14 as shown more clearly in Figure 4.-. The lower end of the pin is surrounded by a compressed spring 15 engaging the lower surface of the ear 9 and is fitted at its extremity with a disk 16 and nut 17 serving as a stop for the lower end of the spring. The

frames

10 and 11 may be adjusted on the pivot pin 14, and the spring 15 creates pressure among the several ears sufficient to retain the lens holders in their positions of adjustment.

The

holders

10 and 11 contain each a mag- 'nifying lens 18 retained'in any preferred manner. It will be seen from Figure 1 that the stop 8 is positioned for engagement by either of the lens holders when disposed directly forward of the shield 3. With a lens holder in this position and the lamp 4: directed towards the object under examination, the device may be turned to shield the eyes of the user from the glare of the lamp, and at the same time the magnifying lens will lie in .the line of vision from the examiner to the object. One of the lens holders may be positioned out of the line of sight as in the case of the holder 11 in Figure 1, and it will be obvious that either one or both or neither of the magnifying lenses may be brought into functioning position as desired.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be .made without departing from the scope of the invention as indicated by the appended claims.

What I claim is 1. A magnifying and illuminating device comprising a lamp socket, a shield carried thereby, and a pair oflens holders pivoted to said shield and mounted to swing in planes parallel to the longitudinal axis of said socket.

2. A magnifying and illuminating device comprising a lamp socket, a shield carried thereby, a lens holder pivoted to said shield and mounted to swing in a-plane parallel to the longitudinal axis of sald socket, and a stop member formed on the forward edge of said shield and engageable by said holder.

3. A magnifying and illuminating device comprising a lam socket, a shield carried thereby, apair oi lens holders pivoted to said shield and mounted to swing in planes parallel to the longitudinal axis of said socket, and a stop member formed at the forward edge of said shield and engageabl by said lens holders.

4. A magnifying and illuminating device comprising a lamp socket, a shield carried thereby, a pivot pin passed through said shield, a pair of lens holders pivoted to the shield by means of said pin, a, spring surrounding said pin, means surrounding said pin for abutment by one end of said spring, the remaining end of said spring engaging one of said pivotally related members whereby to establish frictional engagement among said members.

5. A magnifying and illuminating device comprising a lamp socket, a shieldcarried thereby, a pivot pin passed through said shield, a pair of lens holders pivoted to the shield by means of said pin, a spring surrounding said pin, means surrounding said pin for abutment by one end of saidspring, the remaining end of said spring engaging one of said pivotally rela'ted members whereby to establish frictional engagement among said members, and a stop member formed at the forward edge of said shield and engageable by said holders.

In testimony whereof I aflix my signature.
