Application December 17, 1951, Serial No. 262,013 4 Claims. c1. z-ss This invention relates to garments of deposited latex which are fashioned to be buttoned on when in use so that they can be put on and taken off the wearer with greater facility than similar latex garments which have to be stretched in the process of getting them on or off the wearer.

Garments of deposited latex are usually thin and can be stretched but lack the mechanical strength of such materials as woven fabrics. Difliculties have therefore been experienced in attempts to provide garments of this kind with fastening elements such as buttons or the like, owing to the tendency on the part of such fastening elements to tear the material or to work loose when stress is applied thereto. According to the present invention, buttons are mounted on the garments in such a way that they do not come loose, nor are they so apt to tear the fabric. While the invention may be used in various kinds of garments, its use in connection with baby pants and womens girdles is hereinafter described and is illustrated on the drawings, of which- Figure 1 is a front view of baby pants opened out;

A button such as is used in the garments illustrated in the drawing is shown in Figure 8 and consists of an oval piece 30 of stiff sheet material such as metal or a synthetic resin. Two parallel slits 32 and 34 are cut in the oval piece 30 and the strip 36 of the material between the slits is sprung out of the plane of the rest of the button sufficiently to admit the end portion of a strap 40 which is of soft rubber such as deposited latex and is highly stretchable or extensible. The strip 36 is then pressed back to the plane of the rest of the button, thus pinching the strap 40 in two places where it passes through the slits. Since the material of the strap is highly extensible, it follows that the strap becomes thinner when subjected to longitudinal stresses and elongated, so that it is apt to pull out of the slits. To prevent this, I insert a stop member such as a strand 42 shown in Figure 6 or a strip 44 as shown in Figure 7. These stop elements extend transversely with respect to the strap and are embedded in the material thereof, being preferably located near the free end of the strap, that is, between the extremity of the strap and the nearest slit of the button. This strand 42 or strip 44 is preferably of a material which differs from the material of the strap itself. For example, it may be of rubber which is somewhat stiffer than the soft rubber of the strap, or it may be a strand of textile fibres, or a wire of metal, plastic or othermaterial. The strand 42 or the strip 44- prevents the end portion of the strap from pulling back through the slits 32 and 34 when tension is applied to the strap. The strand or strip may be incorporated in the strap in the manner hereinafter described. it

The button is used to secure together portions of a garment by being thrust through a suitable button-hole which may be in the form of a slit 46 in the garment. In order to reinforce the slit 46 an oval patch 48 (Figure 11) may be applied to or embedded in the material of the garment. For example, Figures 1, 3 and 4 illustrate baby pants which may be formed by dipping a suitable form 49 into a pool of prepared latex and allowing the deposited film of latex to dry on the form. The dipping and drying steps are repeated until a sufficient thickness of latex has been deposited. The latex may be a prepared latex mixture ready to be vulcanized When coagulated or may be pre-vulcanized so that when it dries it becomes a vulcanized film. The baby pants shown in Figures 1, 3 and 4 consist of a sheet or film of deposited latex or the like consisting of two relatively wide portions 5% and 52 connected by a narrower neck 54. In the form of baby pants illustrated in Figure 1 the portion 56 has inturned side margins 56. These are formed by depositing a latex film on both faces of the form which is approximately the same contour as that of the opened out baby pants shown in Figure 1. The film on the front face of the form is cut away to leave the garment shown, the upper portion of this garment being cut to form a series of straps 60 to the ends of which are secured buttons 30 in the manner described. In the lower portion 52 button-holes 46 are provided so that when the lower portion is brought up to overlie the upper portion, the pants may be buttoned up as illustrated in Figure 3 leaving the apertures 62 for the legs of the infant.

The reinforcing patches 48 may be incorporated in a garment by being applied to the film on the form resulting from an initial dip. The patches are applied at the proper places and readily adhere to the sticky film. Subsequent dipping serves to cover the patches and to embed them in the material of the garment as indicated in Figure 9. If desired, each patch may be reinforced by a loop 64 of wire, thread, or other suitable material embedded therein. As illustrated in Figure 11, the patch is made with a thin central portion where the slit is to be made. This thin central portion is surrounded by a rounded ridge 66 which tapers outwardly in thickness to a thin edge 68, so that when the patch is embedded in a garment, the surface contour of the garment about the patch is smooth.

When the buttons are pushed through the button-holes 46, they lie fiat against the surface of the garment in the vicinity of the button-hole. The buttons may be inserted from the inner to the outer surface of the front flap 52 as illustrated in Figures 3 and 4 or, if preferred, may be inserted from the outside in so as to be held between the inner surface of the flap 52 and the body of the infant.

In order to incorporate stop elements 42 in the straps 40, a strand 70 is mounted on the form 49 before the dipping begins. Portions of the strand are held away from the surface of the form by spacing elements 72 on the face of the form so that when the form is dipped, the latex will surround and embed such portions of the thread. To hold the thread firmly against the spacers 72 the thread is caught under fingers 74 which overhang depressions 76 in the face of the form. Recesses and spacers may be arranged on the form in the manner shown in Figure 12. The form is then dipped as often as desired to accumulate a film of suitable thickness thereon. After the film has been dried, vulcanized and stripped from the form it is then cut along the broken lines 84 shown in Figure 12. This cuts away portions of the strand 70, the remaining portions being embedded in the straps which are formed by the cut 84.

A slightly different form of baby pants is shown in Figure 16. The blank from which these baby pants are made, the upper portion of which is shown in Figure 15, is in a single plane and can be cut from sheet stock. If preferred, a form can be dipped and two blanks can be made on one form, the front and rear portions of the film deposited on the faces of the form being simultaneously trimmed along the margins to form the straps 40 shown in Figure 15. A portion of a suitable form 78 is illustrated in Figures 17 and 18, the strand being applied to both faces of the form. In this case spacing blocks 72 are attached to both the front and rear faces of the form and holes 86 extend through the form itself to receive the strand 70. The strand is threaded through the holes as indicated in Figure 18 so that stretches of the strand are supported in taut condition between successive spacers 72. When the dipping has been completed, the strands are cut at the holes 86, the film is stripped from the form and laid fiat, and the front and rear portions are simultaneously cut by a suitable die to form a shape the upper portion 88 of which is illustrated in Figure 15, the lower portion 90 being shown in Figure 16, provided with button-holes 46.

The invention may be employed in other kinds of garments such as the girdle 92 illustrated in Figure 19. Girdles of deposited latex have heretofore been made in a tubular shape of varying circumference to be stretched when put on the wearer and when taken off. It is sometimes difficult to put on a girdle by that method which involves considerable risk of tearing the material and ruining the girdle. Hence, according to the invention, I supply a split girdle having margins to be buttoned together after the girdle has been applied to the body of the wearer. The girdle is preferably formed by dipping a suitable form in a pool of latex in the customary manner. The deposited film is thereafter trimmed and is slit from top to bottom, button-holes 46 being formed at one side of the slit and straps 40 being formed to project from the other side of the slit. Buttons 30 are then mounted on such straps. Button-holes 94 may also be provided along the lower margin of the girdle for the support of garters (not shown) and a crotch piece 96 (Figure 27). As shown, each end of the crotch piece is trimmed to form three short straps 40 with a stop element 42 in each strap, and a button 30 is secured on the end portion of each strap, one such button being shown in Figure 27. Figure 21 shows a girdle as it comes from the form after the slit has been cut and one margin has been cut to form the projecting straps for the buttons. Since it is desirable that the margin having the button-holes overlie the buttons when the garment is laid flat on a supporting surface, one or both side margins of the form itself are curved out of the plane of the form so as to provide extra width to the front portion of a deposited latex girdle as compared with the rear portion thereof. Figure 28 shows in horizontal section a form 98, the side margins 100 of which are curved out of the plane of the form so that the horizontal dimension of the front portion of the film deposited on the form is considerably greater than the corresponding horizontal dimension of the rear portion of the film. Thus when the film is stripped from the form and laid flat on the supporting surface there will be extra width in the front portion which can be used to permit the margin with the button-holes to overlap the end portions of the straps 40 which carry the buttons when the garment is lying flat.

Figure 22 shows in section the shape the film has when it is on a form having one side margin curved out of the plane of the form. Since forms for this kind of garment are customarily metal slabs about one-half inch thick, the curvature of the film at the edges of the form is relatively sharp, as indicated at 101 in Figure 22. The curvature of the film where it followed the curved marginal portion of the form, as at 102, is more gradual so that when the garment is laid on a fiat surface, the curvature 102 is not sufficient to make it hump up, but it takes a shape somewhat as shown in Figure 20, although actually most of the upper layer would then rest on the lower layer.

Figure 23 illustrates a girdle 103 which is partially slit, that is, the slit extends down from the upper portion part way toward the wider lower portion. The margin at one side of the slit is provided with suitable button-holes to cooperate with buttons 30 mounted on straps 40 formed by cutting away portions of the margin on the other side of the slit. Since it is desirable that the finished garment lie fiat when the button-holes are registering with the buttons, extra width is provided for the front portion of the garment by curving the upper portion 104 of one of the side margins of the form 106 out of the plane of the form as indicated in Figure 25. This results in a girdle blank shaped as shown in Figures 24 and 26, Figure 24 showing the blank after the slit has been cut and one margin has been trimmed away to form button straps. When the rearwardly curved portion 108 of the blank has been straightened as when the blank is laid on a horizontal supporting surface, the margins of the slit having button-holes will then overlie the buttons due to the extra width provided by the curved portions.
