Section: summary

BACKGROUND OF THE INVENTION The prior art is aware of various devices adapted to be associated either with x-ray machines to shield various parts of a person's body or of an object or associated with the person or object which are to be treated by x-rays. These shields and their adaptability to either the x-ray machine or the person or object can be seen in U.S. Pat. Nos. 2,426,884; 3,233,248; 3,631,249; 3,678,233; 3,944,838; 3,986,036 and 4,082,957. These patents typify the general state of the art in this area. SUMMARY OF THE INVENTION The present invention relates to shielding devices for x-ray machines which can be readily assembled and mounted thereon in an economical, simple and efficient manner. Simply, the shielding device is comprised of a base member provided with a removable securing means adapted to receive and hold a masking overlay which also is provided with a mating removable means. In one embodiment the overlay can comprise a plurality of similar metallic sheets with co-operating fastening means whereby the thickness can be varied as desired. In another embodiment the overlay can be trapezoidal in shape to vary the passage of x-rays from the edges toward the body of the same. Removable mounting rails of staggered profiles are utilized to mount and position the shields to the x-ray machine with the rails being reversible to accomodate base plates of varying thicknesses.
