' MAGNIFYING AND ILLUMINATING DEVICE Filed May 31 1927 Patented Nov. 19, 1929 UNITED "STATES- PATENT oFFic GHARLES T. BRADY, OF DETROIT, MICHIGAN MAGNIFYING AND ILLUMINATING DEVICE Application filed Mayi31,11927.' Serial No. 195,569.
Thesocket is formed with a shield adapted to cover the lamp and f urther to reflect llght therefrom towards the object underexamination. The shield has a pair oflens holders pivoted there and one or both of these holders may be broughtinto-the line of vision from the observers eye to the objectunder examination. The device comprises still another lens holder adjustably attached to the support and spaced from the shield. This holder is normally beneaththe lamp and may be brought into alignment with the above inentioned holders to modify the magnifying effect. a
The invention is fully disclosed in the following description and in the accompanying drawings, in which Figure 1 is anielevation of the device; Fig. 2 is a detail plan view thereof; Fig. 3 is a plan view of the auxiliary lens support; Q Fig. 4 is a detail longitudinal section there-' of; and Fig. 5 is a detail longitudinal section of the supporting pedestal.
Reference to these views willlnow be made by use of like characters which are employed to designate corresponding parts throughout. The main support for the device consists of a vertical tubular edestal 1 standing on a'base 2. A post 3 is s idably mounted in. the
' pedestal and is surrounded by a collar4 rest-- ing on the upper end of the pedestal as shown in Figure, 5. This upper end is threaded as at 6 for. receiving a cap 7 penetrated by the post and internally threaded at 8-to cooperate ,and lugs.
with the threads 6. An expansi-ble body 9, :such as rubber, surrounds the post 3 between the collar 4 and the top of thecap 7 and may be expanded radially by turningthe cap "downwardly on the pedestal, thereby becoming clamped aroundthe post and .holding the same "in :a xed position.
The upper end of the post 3 is provided with :aifitting 10 to which is attached one end of :a flexible tubing 11 having a socket head 12 at its (other end. This head receives a ball 13 to which is fixed a handle member 14 formed with a lamp socket 15 carrying a shieldtand reflector 16 as disclosed in my co-pending' application Serial No. 195,573, filed May 31, 1927. The edge'of the member 16 is formed with a air of spaced cars 17 adjacent which is formed a curved'stop 18. This construction accommodates a pair of lens holders 19 each having a lug 20 received between the ears and held in this position by a clamp screw 21 passing through the: ears To the clamp 22 having a bracket 23 pivoted thereto. To the bracket is attached'a socket member? 24 b means'of a clamp screw 25 lying at right ang es to the pivotal connection 22" between the-members 22 and 23. The socket receives a tube 26 which in turn receives a rod 27' having a split and expanded inner end 28 as shown in Figure 4. The outer end of the rod is bifurcated as at 29 for supporting another lens holder 30 adapted to be secured therein .bya clamp screw 31.
A conductor 32 1s passed into the fitting 10 through the tubing 11 and handle 14 to -.a lamp 33 inserted in the socket 15. The flow of current to the lamp is controlled by a "screw switch 34 mounted on the lamp socket.
By means of the flexible tubing 11 and the universal coupling 1213betweenthetubeand the lamp assembly the lamp may be directed towardstheobjectunderexamination,withthe lens holders andreflector 16 between the object and the eye of the observer; The holder 30 .is brought into "the line of sight by-gmanipulation of the telescopic parts 26 and 27.
and adjustment at the pivots 22 and-25. Due
to the pivotal mounting of the holders 19,'
lower end of the tub 11 i. fitted a.
either one or both of the magnifying lenses supported thereby may be placed in the line of vision, and the holder 30 may be swung entirely out of the line of sight if desired;
Although a specific embodiment of theinvention has been illustrated and described; it will beunderstood that. various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appending claims.
What I claim is 1. A magnifying and illuminating device comprising a support, a lamp socket having a universal connection therewith, a shield carried by said socket, a pair of lens holders pivoted to said shield, and another lens holder Y adjustably attached to said support and ada ted for alignment with the first named hol ers.
2. A magnifying and illuminating device comprising an extensible support, a lamp socket having a universal connection there with, a shield carried by said socket, a pair of lens holders pivoted to said shield, and another lens holder adjustabl the first named holders.
In testimony whereof I afiix my signature.
