SLIDE FASTENER AND CONCEAIIING MEANS THEREFOR Application filed February 2, 1932. Serial a... 590,340.

This invention relates, generally, to slide fasteners of the type wherein cooperating edges of a bag, garment, curtain, tent or other article, are adapted to be connected b a fas- 5 tener which embodies interlocking e ements provided on the edges of the article and arranged to be engaged and disengaged by a sliding operating device or slider; the interlocking elements constituting means for closing the edges when the slider is moved in one direction and then permitting the edges to open when the slider is moved in the opposite direction; and the invention has reference, more particularly, to a novel 5 improvement in slide fasteners of this character, said improvement embodying the use of means for concealing the interlplcking members and the body portion of the s "der.

' Heretofore, in usinggllide fasteners of this character, the interloc g elements together with the slider-are commonly exterior surface of the bag or other means adapted to be closed and opened by the fastener. This exposure of the fastener is objectionable, not only because the same is not particularly attractive, but especially because water and other foreign matter tends to collect on the interlocking elements and to work in between these elements, thereby interfering with the proper movement of the slider over these elements and in time so reducing their 'efliciency that the same cannot be depended upon toserve their closure function. The exposure of these fasteners is particularly objectionable in cold weather,'at which time moisture collecting upon the fastener, tends to freeze on the same, thereby, rendering the operation of the fastener diflicult or at times impossible. Thus, when these fasteners are used on skating garments, ice collecting in the interlocking elements of the fastener, hinders or even prevents operation of the slider.

The principal object of the present invention is to provide an improved slide fastener and concealing means therefor, which concealing means is adapted to substantially conceal the fastener, thereby protecting the same elements and against foreign maexposed on theterial, while at the same time, said concealing means presents an extremely attractive appearance and prevents the rather unattractive interlocking elements of the fastener from being seen.

Another object of the present invention lies in the provision of a novel improved slide fastener having a slider provided with an operating handle which is connected to the body portion of the slider by a low member pro ecting between the oppose ed es of the concealing means, said plow mem er being designed so as to move along betweenthe opposed edges of the concealing means with a minimum of friction, thereby permitting the slider to be moved easily alon in use.

Another object of the present invention is to provide an improved. slide fastener and concealing means therefor, which concealing means consists of flaps or strip edge portions disposed in meeting relation and overlying the interlocking elements of the slide fastener, the said flaps or edge portions being formed with recesses at the llmits of travel of the slider for accommodating the plow member of the slider.

Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the. following detailed description of the same.

The invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of a cylindrical frameless bag provided with the novel slide fastener and concealing means of this invention.

Fig. 2 is an enlarged fragmentary view of a portion of the structure shown in Fig. 1 and illustrates the slider in operation.

Fig. 3 is a fragmentary, sectional view taken substantially along line 3-3 of Fig. 2 looking in the direction of the arrows.

Fig. 4 is a fragmentary, sectional view taken substantially along line 4-4 of Fig. 2 looking in the direction of the arrows.

' Fig. 5 is a part sectional view taken substantially along line 5-5 of Fig. 2, looking in the direction of the arrows.

Fig. 6 is a fragmentary, sectional view taken substantially along line 6-6 of Fig. 2

looking in the direction of the arrows; and

Fig. 7 is a view similar to Fig. 6 but illustrates a somewhat modified form of construction.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now to'Figs. l to 6 of the drawing, the novel slide fastener and concealing means therefor of this invention is illustrated as applied to a bag of the frameless type. It is to be understood, however, that the present invention is equally applicable to other types of bags or grips and to all articles employing slide fasteners, such as garments, curtains, tents and the like. The reference numeral 1 designates the bag as a whole, which bag may be made of any suitable flexible material, such as leather or textile fabric. The bag 1 isformed adjacent its opening with meeting cover portions or flies 2, 2. Tapes or stringers 3, 3 underlie the cover portions or flies 2, 2 and are sewn to the bag or other body by longitudinal rows of stitching 6, 6' that are spaced r'earwardly from the meeting edges 7 of the cover portions or flies 2, 2. The opposed edges of the tapes 3, 3 have interlocle ing elements a, i clamps thereon in staggered relation.

A manipulating slider has a hollow shaped body portion which its over interlocking elements an is adapted to trarel along the tape I ig and disen- :I1g the it .nents i. The dy portion sides through which the st 3 extend laterally, to di in operative relation to the body 3 The cover portions or flies i of the bg 1 extend into overlying relation to the tapes 3 and the interlocking elements t, and the abutting edges 7 of these cover portions or flies substantially overlie the longitudinal central portion of the fastener means as a whole.

The slider body portion 5 is formed with an upward projection or plow member 8 for receiving the operating handle or tug of the slider, and said plow member projects outwardly between the opposed edges 7 of the cover portions or flies 2. The plow member 8 is made relatively narrow as compared with its length so that this member may slide along between the opposed edges 7 of the cover portions or flies with a minimum of friction. Plow member 8 has pointed or wedge-shaped ends 9 to facilitatethe movement of this plow member along and between the abutting edges 7 of the cover portioris or flies 2. Plow member '8 is preferably formed with slots 10 in its sides for receiving inturned proj ections formed on the slider handle or tug 11, which slots are positioned above the cover portions or fiies.2, and exterlorly 5 of the bag 1. By grasping the handle or tug 11, the plow member andhence the body portion 5 of the slider may be moved in either direction along the length of the ba The opposed cover portions or ies 2 are recessed or indented somewhat at the limits of travel of the slider so as to provide openings 12 for conformably receiving the plow member 8 of the slideron completion of its strokes. With the slider at one end of its travel, as shown in Fig. 1 the plow member 8 proJects upwardly through one of the openings 12, and the opposed edges 7 of the cover or flies 2 of the bag lie in abutting relation all along the length of the bag, thereby com-. pletely covering the underlying interlocking elements 4 in protecting relation thereto,

while at the same-time causing the bag to have a neater and more attractive ap pearance.

In use, if it be. assumed that the bag is in closed position, as shown in Fig. 1, and it is desired to open the bag, it is merely necessary to grasp the handle ortug 11 and pull the slider towards the right, as especially shown in F? g. 2. As the slider commences to move toward the right, the body portion 5 commences to disengage the interlocking elcments 4 while the advancing narrow plow member 8, owing to the pointed or wedge nature of this member, moves readily between the meeting edges 7 of the cover portions r dies 2, so that the slider moves along to separate chin Lilli.-

, portion of the slider is separatin the :nterlockzng elements shown while the plow member 8 passes along between the opposed edges 7 of the cover portions or dies 2. In Fig. 4 the slider is shown as having passed the point at which this section was taken, and efiected the complete disengagement of the bag edge port-ions rearwardly of the slider. Since the handle or tug i1 is positioned above the cover portions or dies 2 of the bag, these cover portions or flies do not interfere with the manipulation of this handle. When the slider has reached the end of its travel, the plow member 8 enters the other term nal opening 12, thereby eflecting the completion of the dlsengagement of the edge portions of the bag opening; It will be apparent that instead of said cover portions or flies 2 forming an integral part of'the ba or other body the same may be provided in t e form of separate-strips 13, su tably. attached to the bag or other body, as,
