Specification of Letters Patent.

Patented Aug. 22, 1922.

Application filed August 2, 1921. Serial No. 489,209.

T 0 all whom it may concern:

Be it known that I, ERNEST O. FREDERIos residing at New York, in the county an State of New York, have invented certain new and useful Imp 'ovements'in Shields, of which the following is a specification.

This invention relates to an improvement in protecting devices or shields, and the prime object of the invention is to provide a new and improved device adapted to' protect the scalp of a person whose hair is being subjected to a heating or steaming operation, such for instance, as when the hair on the head is subjected to what is known as a permanent waving operation.

Other objects and aims of t e invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in thecourse of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting. the invention; and the scope of protection contemplated 'will be indicated in the appended claim.

In the accompanying drawing, wherein I have illustrated a preferredform of embodiment of my invention Figure 1 is a plan view of one embodiment of my invention.

Figure 2 is a sectional view thereof, taken on the line 2--2 of Figure 1.

Figure 3 is a plan view of a modified form of my invention.

Figure 4 is a sectional view,

line 44 of Figure 3; and

Figure.5 is a view in elevation, artly in section, showing the manner in w ich my improved shield 1s employed in actual taken on the practice.

Figure 6 is a side view of a shield in use with a strand of hair introduced therethrough, the radial fingers being in 'flexed position, the flexure being somewhat exaggerated.

Figure with the fingers in flexed position, as shown in Figure 6.

Similar reference characters refer to similar parts in the several views of the drawing.

Before proceeding with a description of the structural features of my invention, it may here be noted that in the operation 0 permanent hair waving" it is customary to divide the hair into several independent 7 is a sectional view of the shield gin of the ring.

strands, and to wind each of said strands from the root upward, upon a metallic curler, to place upon each wound strand a moistened hair treating device, over which is positioned an electric heater.

During the operation of the electric heaters steam is generated from the moistened-hair treating ingredient, and which steam if allowed freely to escape from the hair waving device toward the head of the subject, if not taken care of, will burn or scald the head of the subject being treated.

The object of the present invention, therefore, is to provide a shield of such construction that it may be readily positioned about the coiled hair, and whichwill afiord a complete protection to the scalp of the subject whose hair is being treated.

Another object of the present invention is to provide a shield of such construction that it may be readily positioned about a strand of hair, and that it may be'flexed so asto bear firmly agains suchstrand and thereby to anchor the shield against movement relative thereto, in order -to afl'ord com-.

plete protection to the wearer.

' Referring now tothe drawing, the reference numeral 1 denotes a disk, preferably composed of a fibrous material, commonly called fibre,-alth'ough it is understood that other suitable materials may be substituted therefor such as felt, said disk being provided at its central portion with an aperture 2. Extending in radial directions from said aperture 2, are slits 3.

By the construction outlined, the disc may be considered to be in the form of a ring or of somewhat triangular shape, are susoepti-- ble of flexure about their bases which lie on the arc of the circle forming the inner mar- When the ends of the radial members are flexed out of the plane of the ring, it will be understood, of course, that the central aperture bounded by the f ends will be increased slightly in size, so that -the shield is capable of having inserted through it a strand of hair of somewhat larger diameter than the diameter of the aperture. By this arrangement of parts, the shield has a strand introduced through the central aperture, and thereby the ends of the radial members are flexed slightly. The ends accordingly bear firmly against the strand and anchor the shield securely in position, so that there is no possibility that the shield will slip along the strand into con-. tact with the scalp. The manner in which the shield is held in position along the strand by the radial members being flexed, is clearly shown in Figures 6 and 7. I

It will be understood, of course, that the shield must be of heat-resistant material, and at the same time, of a fair degree of elasticity so that the ends of the radial members will not be permanently bent out of the plane of the ring by continued use. Again it is necessary that the member's be flexible so that theshield may be readily adjusted in position.

It is further to be understood that While the shield is of heat resistant material so as to'protect the scalp from escaping steam, it is important that it be held securely in position on the strand since it is heated up by the escaping steam and mayreach a temperature which would produce discomfort or even pain if allowed to touch the scalp. By the use of fibrous material in the form Ihave shown, the shield is anchored securely in position and there is no possibility of the shield slipping down along the strand into contact with the scalp.

In Figures 1 and 2 I have shown the slits as being located at right angles to each other, and in Figures 3 and 4 I have shown sald slits as being located at a greaterangle from each other, it being understood, of course, that the number of slits extending from said aperture may bevaried at will.

It will be noted from an examination of Figure 5 of the drawing, that when the hair is wound upon the curler, the shield may be inserted over said'coiled hair, and that when the same has been placed in postion near the scalp of the subject, the portions 4 of the shield, separated by the radially extending slits, can be placed in such position as to form.

a complete shield for the scalp adjacent theroots of the hair comprising the strand wound upon the curler. In other words, the shield will adjust itself uponrthe scalp of the subject so as to prevent any escaping steam from scalding the hair of the subject.

As many chan es could be made in this construction wit out departing from the scope ofthe following claim, it is intended that all matter contained in'the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

Having thus described'my invention what I claim as new and desire to secure by Letters Patent is:

A protective shield comprising an annular piece of fibrous material having a plurality of independent members s aced apart and projecting radially from t e inner margin thereof, the ends of said members being formed so as to bound a substantially circular aperture, said members being flexible so as to permit of a flexure out of the plane of said shield wherehy to permit the introduction through said aperture of a strand of hair of greater diameter than said aperture, and said ends being adapted to bear firmly against said strand when said members are in flexed position, whereby to hold said shield against movement relative to said strand.

In testimony whereof, I aflix my signature
