2 Claims. (01. 250-108) This invention relates to protective aprons, such as are worn by operatives of X-ray apparatus for shielding the body against undesirable, harmful effect of X-rays.
One object of the invention is to provide an 5 to the side seams l3fand upto the shoulder seams improved protective shield or apron, of the ch'ari l, is of the construction illustrated in Fig. 3. acter described, which is of simple construction It includes a shielding member I5, in the form and of pleasing appearance; which provides maxof a single sheet or panel made'of plastic maimum X-ray protection and avoids leakage paths terial, such as rubber, eithe natural y for stray ray effects; which is easy to apply to thetic, or any suitable rubber substitute, impregand remove from the body; which offers increased nated with or containing a material opaque to support for and distribution of the load; and X-rays, such as lead or lead oxides or other comwhich tends to hang close to the body when in pounds of lead.

The; entire front of the garment, including the skirt II and the front of the upper part It] out the Wings may be connected by tie bands25,
3 which usually are made long enough to bring around the waist, like a belt, for tying in the front.
The garment described is quite simple to apply to and remove from the wearer. In putting it on the arms are passed through the arm holes and the weight of the garment is immediately supported upon and distributed over the shoulders, and is not hung around the neck. Indeed, because the shielding portion of the garment has extra width and has the wings I9 fastened to it, the garment hangs fairly close to the wearer when he bends over, even without the tie straps 25, but when the latter are employed the garment hugs the wearer closely and distributes the weight so that any of the usual working operations may be performed without undue fatigue.
All stitches are close to the edges of the various parts, and not considerably inwardly therefrom, as when straps are employed, necessitating rivets or strong stitches through the body of the sheet and far enough in to prevent tearing out.
The arrangement described also avoids X-ray leakage through such openings.
Further advantages of the invention will be apparent to those skilled in the art.
What I claim is:
l. A sleeveless X-ray shield of generally apron form for use by X-ray operatives, including a single sheet of rubber-like material loaded with heavy material opaque to X-rays, said sheet being of generally rectangular shape with vertical side edges and of a size to completely shield the body vertically from the neckline to approximately the knees and horizontally outwardly to vertical lines beneath the arms, a textile fabric bag-like cover shaped to correspond with and enclosing said sheet, said sheet and cover having laterally spaced top portions one over each shoulder and each of substantially full shoulder width, and back wing members made of textile fabric having upper portions joined to the spaced shoulder portions of the cover along relatively long horizontal shoulder lines and lower portions joined to the vertical edges of the cover along the under-arm lines, the said back wing members having generally horizontal bottom edges and vertical edges which extend diagonally downwardly and converge from the neck ends of the spaced shoulder portions of the cover to the ends of said bottom edges, where said wings closely neighbor each other when the shield is in use, said lower portions being provided with connecting means and lying entirely beyond the area of the cover and sheet and being free to conform to and hug the body, whereby the heavy weight of the shield is distributed over the full width of both shoulders and a substantial area of the lower back.
2. A sleeveless X-ray shield of the character described in claim 1, in which said fabric cover and back wing members are secured to each other and to said sheet by rows of stitches extending through said sheet, the cover therefor and the back wing members.
