CLAMP FOR EXAMINATION DEVICES Filed May 31, 1927 30 and Patented Dec. 2, 1930' CHARLES r. BRADY, or DETROIT, moment CLAMP r03 EXAMINATION evious Application filed May 31,

The present invention pertains to a novel clamp constructed for the support of examination devices, and has for its prinolpal object a device of this character attachable to supporting bodies of various shapes and adapted to maintain the supported ob ect n any desired position regardless of theposltion of the clamp on the supporting body.

In the accomplishment of this object, the

relatively adjustable clamp elements are formed with registering curved and fiat depressions so that the clamp may be applled to curved and fiat bodies. One of the elements is formed with an axial projectlon which carries a. stem perpendicular thereto. The projection and stem are formed w th sockets, also perpendicular to each other, for receiving the examination device to be supported by the clamp. These sockets permlt insertion of the supported member in one or the other of two perpendicular directions regardless of the position assumed by the clamp after its application to the supportlng body.

The invention is fully disclosed in the following description and in the accompanying drawing, in which-V- Figure 1 is an elevation of the device applied to a curved member;

Fig. 2 is a perspective view of the clamp;

Fig. 3 is an elevation of the clamp applied to a flat member.

Reference to these views will now be made by use of like characters which are employed to designate correspondingparts throughout. The clamp consistsof apair of relatively adjustable members 1 and 2 which aresubstantially identical except for an extension 3 at one end of the member 1. Each of the members has a flat depression, 4 and a curved depression 5, and the members are so disposed that the depressions of one register with like depressions of the other. The members are joined and rendered mutually adjustable by a clamp screw 6 threaded therethrough between the depressions 4 and 5. r

The curved depressions 5 permit the device to be clamped upon a tubular'or cylindrical member 7 as in Figure 1, while the flat depressions 2 enable it to be fixed to a flat mem- 1927. Serial no. 195,570.

ber 8, such as theback of a chair'as illustrated in'Figure 3.

The extension 3 is formed at its free end with a socket 9 which may be smooth or threaded according to the nature of the member to be fitted and supported therein. The extension 3 isalso formed with a stem 10 perpendicularthereto and having a socket 11 similar to the socket 9. The supported element in this instance is a flexible tubing 12 having its free end 13 adapted for entering into either socket. The remaining end of the tube 12 is equipped with a socket head 14receiving a ball 15. To the ball is fixed a handle 16 formed with a lamp socket 17 and a reflector 18 in the manner disclosed in my co-pending application.

The reflector is formed with a lens holder 19 and further supports a pivoted lens holder 20 as shown in'my co-pending application.

A conductor 21 is entered into the lower end of the tubing and passed through the tubing and handle 16 to a lamp 22 fitted in thesocket 17.

Whether the clamp is applied to a cylindrical or fiat support, and whether the axis of the clamp lies vertically or horizontally, the stem 13 may be fitted into either a vertical or a horizontal socket due to the perpendicular relation of the sockets. Another clamp 23 is applicable either to the extension 3 or the stem 10 for supporting another lensin alignment with the holders 19 and 20. The support for the third lens includes a socket member 24 pivoted to the clamp 23, a tube 25 fitted into the socket 24, and a rod 26 telescoping in the tube 25 and having at its outer end a clamp 27 maintaining a lens holder 28. 7

After the device has been supported in the manner already described, the lamp assembly is adjusted by the flexible tubing 12 andits universal connection 1415 to the tubing so that the lamp 22 throws light on the object under examination and the, shield 18 and magnifying lens-are positioned between the object and the eye of the observer. The examiner may then adjust the several lens holders in order. to bring one, two, or all of the lenses in'his line of vision.

I Although a specific embodiment of the in- PA-TEN OFFICE vention 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. In a support for examination devices, a pair of arms each having at one end a flat depression oppositely disposed to each other, and at the other end a curved depression each oppositely disposed to the other,=a--supporting socket carried by one of the said arms and projecting on the longitudinal axis of'such arm, and a clamp screwtthreaded through openings tapped in the said arms.

2. In a support for examination devices, a pair of arms each having at one end a flat depression oppositely disposed to each other, and at the other end a curved depression each oppositely disposed to the other, a supporting socket carried by one of the said arms and projecting on the longitudinal axis of such arm, another supporting socket carried by the aforesaid supporting socket the longitudinal axis of which is at right angles to the longitudinal axis of the first mentioned supporting socket, and a clamp screwthreaded through openings tapped in said arms.

In testimony whereof I aflix my signature.

CHARLES T. BRADY.
