Briefly stated the present invention provides a dress shield. for protecting garments .irom the deleterious sheets of .body nerspiratiorr The shield designed for placement in the armscyc of .a garment in such :manner that impervious interior faces hi the shield are in engagement with the garment being worn by the user. :EX- terior faces of shape similar .to the interior faces are adjoinedthereto insuoh manner as to provide two separate pockets having an upwardly disposed opening adjacent the seam of the garmerit. Separate moisture absorbing pads are provided for insertion in said pockets and are readily removable therefrom whenever the :garment is removed and it is desired to change the pads due to theabso-rpti'on of perspiration.
In order that body perspiration :may be alesorbed by the absorbent pads, :onenings or cut- .outs are formed in the exterior .iace of said pockets. These openings are of novel shape. size andplacementzso that 'all theperspiration'exu-ded by the wearer will be absorbed by the pad. .As a furtherieatu-re of this inventionthe dress shield is of a novel geometrical shape which tends to protect the garment 0f the wearer even while the wearersn arms are raised to a Working position.
Referring now to the drawings the features of this invention will be more fully described and explained. In Figs. .11 and? it will be noted that the applicant provides a garment shield 1.! made up of four "similarly shaped members, .at leasttwo :of the :members l3 and Marc formed of an impervious washable fmaterial and are attached together along an upper .cnrved edge H5- These interior ;members :13 and M are normally in .engagemen't with the garment being worn by the user and when the shield H is property placed in the garmentthe member ilfi' will beinengagement with the .arm of the garment while the member M is in engagement with the bodysOf the gannenti The upper curved edge I15 will itself be adjacent to the armscye of the garment. Prefenably .the members [3 and M :are of a plasticor otherwise washablematerial which :is impervious to the moistureof perspiration.
The other two :of the above mentioned four members are the exterior members I! and '18. These memberslikewise may be made of the same type of materials .as that used vfor the "interior members 13 and -14. If the exterior members '41 and I 8 are .made of :the same type :of material, however, it is necessary that cutouts or apertures I9 to be formed in the face thereof. Inasmuch as these interior members I! and I8 are in engagement with the body of the wearer it will be readily apparent that these apertures are provided so that body perspiration may be introduced into the interior of the pocket formed by joining the members I! and I8 to the internal members I3 and I4 respectively along the lower edges 2| and 22. When the edges have been joined together by means of stitching as shown in Figs. 1 and 3 or by heat sealing the plastic fabric as shown in Fig. 4, it will be apparent that this device provides two pockets in side by side arrangement into which perspiration absorbing pads 23 may be placed.
The pads 23 are themselves made of any suitably absorbent material such as soft paper, fabric or the like and in the embodiment shown the applicant has provided a pad having a soft, paper and cotton filler 24 and an exterior fabric binder 26 similar to cheesecloth or the like. A deodorant may be used in the pad if desired.
The novel shape of the pads 23 and likewise of the dress shield itself is best explained in conjunction with Fig. 2. In this figure it will .be noted that the applicant provides a pad having, an upper edge 21 of regular curvature which in actuality is a segment of a circle. The exterior edge 28 is of compound curvature which closely approximates the curvature of a cardioid. While the product actually manufactured or which might serve the purposes of this invention would not necessarily assume this exact shape, the curvature which results from the construction indicated in Fig. 2 closely conforms to that desired by the applicant. If the X and Y axes are taken as indicated in Fig. 2 and if the primary circle of construction is of a diameter equal to the diameter of the circle of construction 29 as shown, and if the revolved circle 3I is of identical diameter the curve traced by the point P on the circumference of the circle 3 I as it is rolled about the stationary circle 29 will correspond to the curvature of the lower edge 28. The location of this point P with respect to the X and Y axes and therefore the location of the curve 28 is determined by the formula Rho=a(1cos 0) when Rho is the distance from the center 0 of the coordinate axes X and Y, when a is equal to the diameter of the circles 29 and 3|, and when 0 is the angle the point P makes with the X and Y axes. The curve 28 shown in Fig. 2 can actually be derived through use of this formula. However it should be noted that the representation of Fig. 2 is correct only if the drawing sheet is viewed from an upside down position.
The construction indicated on Fig. 2 is likewise useful in determining the location and curvature of the upper edge 21. If an axis Y is passed parallel to the Y axis and tangent to the circles of construction 29 and 3| at their point of tangency, the intersection of this axis Y with an axis X which is located tangent to the uppermost limit of the circles of construction 29 and 3|, determines the location of the center of a circle of which the curve 21 is a segment. This construction is useful in a still further manner inasmuch as the axis Y determined as above corresponds with the location of the seam of the garment with which the dress shield is to be used.
If a dress shield made according to the foregoing description is attached in the garment by means of safety pins 32 or the like in such position that the seam of the garment coincides with the axis Y, the shield of this invention will tend lifted to this normal position and if prior forms of shields are shifted to give this requisite protection they become too bulky or otherwise bothersome to the wearer. By reason of the form shown the applicant therefore provides a shield which offers greater protection to the wearers garment without being too bulky or cumbersome.
Other advantages of the applicants device are inherent in the provision of the positive juncture of the interior faces I3 and I4 along the curved edge I 6. By reason of this juncture no perspiration is allowed to pass downwardly betweenthe pockets and onto the garment since the faces I3 and I4 and the juncture thereof provide animpervious garment protecting shield. Inasmuch as the edges of the faces I3 and I4 are turned under after they are stitched or heat sealed the edge It is a smooth surface that will not chafe the wearers armpit. A further advantage of the applicants device is inherent in the provision of openings I9 in the exterior faces IT and I8. These openings I9 are of such size and placementthat any excessive perspiration of a quan- 1 tity greater than that which can readily be absorbed by the pads '23 will be retained'in the area defined by the line 33 and the lower edges 2! and 22 of the separate pockets. It will be noticed that no openings are provided in this general area so entrapped moisture cannotescape but will be retained in the pocket by the sealed edges 2I and 22. In the arrangement of openings I9 it should be noted that slits 20 are provided under the oval shaped openings I9. These slits 2E3 tend to entrain any moisture which travels down the outer surface of faces I! and I8 between openings I9.
Further it should be noted that the applicant provides pockets whichare open along their upper edge in such manner that the shield II need not be removed from the garment when the pads 23 are to be replaced. When the wearer wishes to change the pads in the shield II the pads 23 may be removed directly from the separate pockets and new pads may be replaced therein. Since the interior and exterior surfaces I3, I4, I! and I8 are made of a moisture impervious material, any perspiration or moisture on the shield may be removed at the time of pad replacement by the simple expedient of washing or wiping the perspiration therefrom, and this operation too may be carried out without removing the shield from the garment.
While one specific form of this invention has been shown and described it should be under stood that the applicant is not to be limited strictly to the shape shown and described. The essential purpose of providing the form shown is to provide added protection for the wearers garment whenever the wearers arms are raised to a working position. Prior forms of dress shields were generally lunar in shape and the term of cardioid shape or of cardioid curvature in the appended claims is intended to distinguish from such previous shapes and to describe any shape providing a segment extending forwardly with respect to the armscye of the garment. It will be obvious that many modified shapes and forms might :be adapted to serve the purpose of this invention in this respect and for that reason the inventor should not be limited to the single technical form shown and described, but should only be limited Within the scope of the following claims and by the terminology used therein as modified by the specific definitions included in this specification.
