I SHAPING DEVICE FOR NAL-COATING ELEMENTS Filed July 5, 1952 IIIA l iNvENToR SHAPING DEVICE FOR NAIL-COATING ELEMENTS Boris Bogoslowsky, Jackson Heights, N. Y.; Elizabeth Bogoslowsky, executrix of Boris Bogoslowsky, deceased Application July 5, 1952, Serial No. 297,366

7 Claims. (Cl. 164-41) This invention relates to the ornamental coating of human nails and more particularly to a novel and improved device for pre-shaping colored plastic nail coating blanks to fit fingernails of diiferent sizes. While the present device can be used for shaping nail-coating blanks of many diiferent types, its utility can be most conveniently described in relation to a particular kind of blank and hence for purposes of illustration the device will be described with reference to its use in producing nail-coating elements of the type disclosed in my copending application Serial No. 108,267, iiled August 3, 1949, now Patent No. 2,688,331.

The nail-coating elements of my said co-pending application comprise a thin sheet of plastic, metal foil or the like having a layer of pressure-sensitive adhesive thereon. The nail-coating material is mounted by means of the adhesive on a suitable support such as another plastic, a piece of wax paper or the like. The nature of the support used is such that when the nail-coating material and support are separated the adhesive adheres to the nailcoating material and can be readily stripped from the support. The nail-coating elements have a curved end, the curvature of which conforms with that of the cuticle of a human nail. The nail coating is applied by stripping the plastic and associated adhesive from its support, positioning the coating on a nail with its curved end aligned with the cuticle and the opposite end overhanging the end of the fingernail, pressing the coating material against the nail to cause it to adhere thereto and filing the end of the nail to remove excess coating material.

One of the principal problems encountered in producing nail-coating elements of this type arises out of the fact that the sizes of human lingernails vary over a rather wide range. Since the length of the nail-coating element is adjusted after the coating is applied to the nail, no ditiiculty is encountered with respect to variations in the length of diiferent fingernails. However, in order to take care of the problem of variations in the widths of different fingernails, it is necessary to produce the nail-coating elements in a variety of different widths, thus complicating the manufacture and distribution of such nail-coating elements.

It is accordingly an object of the present invention to provide a shaping device that can be conveniently employed by the user of the nail-coating material to shape a nail-coating blank to fit any size iinger-or-toe-nail. It is another object of the invention to provide a device of this kind that is simple and inexpensive to construct. it is still another object of the invention to provide a device that is readily adjustable to produce nail coatings in a wide variety of sizes so that the nail-coating material can be accurately tted to the different fingeror toe-nails. Other objects of the invention will be in part obvious and in part pointed out hereafter.

nited States Patent! i rice The many objects and advantages of the present invention can best be understood and appreciated by reference to the accompanying drawing which shows a device incorporating a preferred embodiment of the present invention and wherein:

Figure 2 is a vertical section taken on the line 2-2 of Figure 1 and showing particularly the pivotal mounting of the shearing member;

Figure 3 is a vertical section taken on the line 3 3 of Figure 2 and showing particularly the adjustable abutment that defines one of the inner edges of the gauging slot;

Figure 4 is a vertical section taken on the line 4-4 of Figure 3 and showing a nail-coating blank positioned against the adjustable abutment and also the mode of adjustment of the adjustable abutment;

Figure 5 is a horizontal section taken on the line 5 5 of Figure 3 and further showing the adjustable abutment of the gauging slot;

Figure 6 is a perspective view of a nail-coating blank suitable for use with the present device;

Figure 7 is a perspective View of the blank or" Figure 6 folded for insertion in the gauging slot; and

Figure 8 is a perspective View of a trimmed blank after it has been removed from the gauging slot and opened up.

Referring to the drawings and more particularly to Figures l and 2, the numeral 1G generally designates a casing preferably made of plastic and adapted to contain a supply of nail-coating blanks to be shaped. The casing 10 is provided with a pvoted cover 12. Extending across the upper portion of casing 10 there is a wall member le of L-shaped cross-section that denes with the casing a chamber 16.

Referring to Figures l and 3, formed within the chamber 16 there is a shelf 18 that cooperates with the top 26 of casing 10 to deiine a gauging slot 22. As best shown in Figure l, the open edge of slot 22 extends along a part of the side and one end of casing 10. The lateral extent of gauging slot 22 is further defined (see Fig. 5) by a fixed abutment 24 and an adjustable abutment 26.

Reverting to Fig. 1, extending around one end of the casing 10, near the top thereof, there is a U-shaped metal band 28, the upper edge 30 of which is flush with the top of shelf 18. As more fully explained hereafter, the upper edge 30 of band 28 forms a shaping edge against which the nail-coating blank is trimmed. The ends of the U-shaped band 28 are secured to the casing by a pin 32 that extends through the chamber 16 and forms a pivotal mounting for a U-shaped shearing member 34, which, as best shown in Fig. l, has a cutting edge 3e adapted to co-operate with the shaping edge 30 of metal band 23 to cut a blank positioned therebetween. Still referring to Fig. 1, the end portion 38 of cutting edge 36 slopes upwardly somewhat to form an acute angle with the corresponding portion of shaping edge 33 to facilitate cutting of the material of the blank at the end thereof. The shearing member 34 is provided with a tab 35 by means of which it can be depressed to cut a blank positioned in slot 22.

The mode of adjustment of the adjustable abutment 26 is best shown in Figure 4 of the drawings. Referring to Figure 4, rotatably mounted in the side walls of chamber 16, there is a threaded rod 40 that is of reduced diameter at the points where it passes through walls of the chamber 16 to form shoulders 42 that cooperate with o the walls of the chamber to prevent axial movement of rod 40. The rod 40 is threaded through a depending vertical arm 43 of the abutment 26 and is provided outside the casing 10 with a knob 44 by means of which it can be rotated to adjust the position of abutment 26 with respect to the shaping edge 30.

Referring now to Figure 6 of the drawing. The nailcoating blank there shown comprises a thin piece of colored plastic 46 which has a layer of pressure-sensitive adhesive on its under side by means of which it is mounted on a support 48. A flap 50 of the plastic layer 46 is left free from adhesive to facilitate separation of the plastic from its support. The blank of Figure 6 is folded along the dotted line to give the structure shown in l Figure 7 and is then inserted in the present device for cutting along the dotted line of Figure 7. Thereafter, the portion of the blank remaining in the slot 22 is withdrawn and opened up to give the structure shown in Fig. 8. After shaping, the plastic layer 46 is removed from the support 48 by grasping flap 50 and pulling the .two

layers apart. The plastic layer 46 is then applied to the finger-nail as previously described herein and more fully described in my co-pending application Serial No. 108,267 referred to above.

In using the present device, the abutment 26 is first positioned in such manner that the distance between outer surface of shaping edge 30 and the proximate surface of abutment 26 is one-half the desired width of the nailcoating element. With the shearing member 34 in raised position as in Figure l, a blank folded as shown in Figure 7 is inserted in the slot 22 in such manner that the end having the iiap 50 bears against the fixed abutment 24 and the fold bears against the abutment 26 (see Figure 4). As shown in Figures 1 and 4, the top 20 of casing 10 is provided with a series of reference lines 52 to which suitable reference characters can be applied to facilitate proper positioning of the abutment 26 with respect to the shaping edge 30 to produce the desired width of nailcoating element.

When the nail-coating blank has been inserted in slot 22, the shearing member 34 is pressed downwardly by manual pressure exerted on the tab 35 and the portion of the blank extending outwardly from the shaping edge 30 is trimmed off. As best shown in Figure 5, the shaping edge 30 has a configuration corresponding to one-half the cuticle of a finger-nail and since the blank is folded before insertion in slot 22, both sides and the curved end of the blank are cut to the proper shape in a single operation. As previously pointed out, the end 38 of cutting edge 36 forms an acute angle with the end portion of shaping edge 30 and thus a clean cut is achieved not only along the side portions of the nail-coating element but also along the curved end as well.

From the foregoing description it should be apparent that the present invention provides a structure capable of achieving the several objects outlined at the beginning of the present specification. Thus the present device is simple to construct and operate and can be easily adjusted to produce nail-coating elements having any desired width within the range normally encountered in human nails. It is, of course, to be understood that the foregoing description is illustrative only and that numerous changes can be made in the specific embodiment disclosed without departing from the spirit of the invention as defined in the appended claims.
