(Ci. SSL-39) p 4 Claims The .present invention relates Yto magnifying glass attachments lwhich may be removably mounted upon electric lamp reflector, and has for its principal object the provision ofa shield with a magnifying glass mounted therein, and which may be removably attached tothe lamp reiie'ctor, and angularly adjusted thereon, for the purpose of freeing the hands of the user, eliminating the necessity of handling the object examined by one hand and a magnifying glass by the other, permitting the user to have his both hands free to handle the object while examining an object under the magnifying glass.

A still further object of the present invention is the provision of a shield within which a magnifying glass is mounted, and which is suitably formed along one of its edges to removably engage a circumferential bead formed in electric lamp shades or reflectors in electric lamps of desk type, and wherein the lamp and the reflector are supported by a flexible tube whereby the position of the reflector may be adjusted.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing forming a, part of this application and in which like designating characters refer to corresponding parts throughout the several Views;

Fig. l is a side elevational view of an electric lamp reflector with the present device attached thereto in an operative position;

Fig. 2 is an end elevational View of the electric lamp reflector with the present device attached thereto, the latter being shown in a side elevation;

Fig. 3 is a cross-sectional view on line 3-3 of Fig. 1; and

Fig. 4 is a cross-sectional view on line 4-4 of Fig. 1.

Referring in detail to the present drawing there is shown therein an electric lamp shade or reflector I which is adapted to receive an electric bulb (not shown), and which is attachable to a socket Il, which in turn is carried by a flexible tube -I2 through which electric wires extend and connect with the electric bulb terminals in socket Il. Reflector I0 is provided with an outwardly extending bead I3 integrally formed with the body of the reflector and along its marginal edge.

The .present invention, intended to cooperate with the lamp reilector I0, includes shield Iii, which may be of any desired shape or formation, and which, adjacent one of its edges isangular-l'y bent as at I5. The edge of said shield' I4 adjacent bend I5 is slightly curved or flanged to affect downwardly turned lip Iii .for the purpose of engaging said bead I3 outwardly thereof land from an upward direction, as is clearly seen in Fig. 4.

Cooperating with shield I4 is a pair of oblong resilient plates I 'I pivoted by one of their ends upon bolt I 8, provided with head I9 in contact with the outer face of shield I 4, and having shank 20 upon which plate Il is set for horizontal angular swinging movement, and held in spaced position from shield I 4 and nut 2| by means of a pair of interposed washers 22. Said nut 2| remains in a threaded engagement with the reduced outer end of said bolt I8, as is seen in Fig. 4.

From the hereinabove description it will be` readily seen that lip I5 engages bead I3, and plates I1, bearing upon bead I3 from below, retain shield I4 in an attached, adjusted position, upon reflector Ill. By angularly swinging plates I1, the same may be entirely disengaged from relector I il, thereby permitting removal of shield I 4 therefrom.

'Struck out from shield I4 and centrally thereof, is a cylindrical socket 23, provided at its outer free end with an inwardly extending horizontal Ila-nge 24,which remains in a perpendicular position with respect to socket 23. Inserted within said cylindrical socket 23, and supported at its margin by Ilange 24 is magnifying glass 25.

Insertable within said socket 23 and frictionally held therewithin is a retaining ring 26, having an inwardly extending flange 2l., which, cooperating with flange 24, and bearing against the opposite face of magnifying glass 25 retains the same within socket 23 and in a rigid relation therewith.

From the hereinabove description it will be apparent that shield I4 may be angularly adjusted upon reector l 0. It will also be seen that the object to be observed under the magnifying glass is placed in back thereof and below reflector Ii), and illuminated by the light from the electric bulb in the reflector. The observers both hands may be used for handling the object under observation.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention asV claimed.

What I claim as new is:

1. A magnifying glass fixture attachable to a lamp reflector having a bead, comprising a magnifying glass mounting shield, a downwardly projecting lip along the marginal edge of said shield for superimposing said bead, and a plurality of resilient plates in pivotal engagement with said shield for engaging said bead at points substantially diametrically opposite from those at which said lip engages said bead, said plates being resilient in a plane substantially normal to the plane of the pivotal movement of said plates.

2. As an article of manufacture a magnifying glass fixture comprising a plate, a socket integrally formed with said plate for receiving a magnifyl ing glass therewithin, a lip angularly depending from said plate, and a plurality of resilient plates in pivotal engagement with said plate, normally lin transverse relation with said lip, and adapted to be angularly swung upon their pivots away from said lip, said swinging movement of said plates being in a plane disposed at an angle to thev resilient movement of said plates.

3. In combination with a lamp reflector of the type having a substantially annular body portion and a bead along its marginal edge, a magnifying glass mounting shield, one edge of said shield being of annular formation corresponding to the contour of the body portion of said reflector, an angularly depending lip from said shield and along said edge, said lip being adapted to superimpose and engage said bead when said annular edge of said shield is in contact With the body portion of said reflector, and means upon said shield for engaging said bead at points substantially diametrically opposite from those at which said lip engages the same.

4. In combination with a lamp reflector of the type having a substantially annular body portion and a bead along its marginal edge, a magnifying glass mounting shield, one edge of said shield being of annular formation corresponding to the contour of the body portion of said reiiector, an angularly depending lip from said shield and along said edge, said lip being adapted to superimpose and engage said bead when said annular edge of said shield is in contact with' the body portion of said rei-lector, and a plurality of resilient plates in pivotal engagement with said shield for engaging said bead at points substantially diametrically opposite from those at which l said lip engages the same.
