'Ihis invention relates in general to separable fasteners of the slide-operated type including two complemental series of locking members or fastener elements each spaced longitudinally of the edge of one of two pieces of material or tapes and in substantially the planes of said pieces of material or tapes, and an actuating member slidable over said locking members to cause the locking members of one series to engage and disengage the locking members of the other series. More particularly my invention contemplates a novel and improved construction of separable fastener of this character especially but not exclusively for use on garments, pocketbocks, garment bags, and so forth, wherein the locking members and portions of the actuating member shall be covered so as to be concealed from view and prevented from contacting with adjacent articles, for example another garment.

Certain known separable fasteners of this general character have the actuating member completely overlying the locking members and hooked over or engaging the root ends of the locking members, i. e., the ends secured to the tapes, at both sides of the pieces of material or tape, and a cover ap is secured to each tape beyond the root ends of the locking members and overlies the locking members and the major portion of said actuating member. 'I'his structure has many disadvantages in that the free portions of the flaps may fold so as to expose the locking members, and become ravelled or worn by contact with the actuating member.

In other types, a cover strip is applied over each series of locking members and is arranged beneath or enclosed by the actuating member. These types are objectionable in that-the cover strips become Worn by sliding of the actuating members thereover, and the cover strips do not cover the actuating members at all so that they are completely exposed to view and to contact with adjacent articles or garments.

Another object of my invention is to provide a separable fastener of the general character described embodying novel and improved features of construction, having the locking members secured at one end to the corresponding piece of material and their other ends projecting beyond the edge of said piece to engage the locking members on the other piece, an actuating member slidable over the locking members, and a cover upon one side of each of said pieces of material overlying said locking members and said actuating member, with one edge approximately coincident with said projecting ends of the locking members, said covers being fastened to the corresponding pieces of material intermediate the ends of said locking members so that there shall be a minimum tendency of the free edges of the covers to fold back in such a manner as to expose the locking members. 5

A further object is to provide a separable fastener of this' character embodying a novel and improved actuating member which has two spaced and parallel portions overlying opposite sides of the locking members and slidable thereon, one of 10 said portions having side anges engaging behind the ends of the locking members secured to the pieces of material, and the side edges of the other portion 'of the actuating member lying between the ends of the locking members, whereby 15 the actuating member shall be light in weight and of minimum bulk, in combination with the edge of a garment or other p iece of material arranged in overlying relation to the locking members and the actuating member to serve as a cover therefor 2O and be fastened to the tape closely adjacent the edge of the garment and between and closely adjacent the locking members, so that there shall be a minimum tendency for the free edges of the garment to flap or fold backwardly, and the edges 25 of the garment shall not be disturbed, rubbed or worn by manipulation of the actuating member.

Other objects are to provide such a separable fastener including a cover to overlie the locking members and the second-mentioned portion of 30 said actuating member upon one side of each of said pieces of material with one edge approximately coincident with the projecting end of said locking members, and stitching passing through said cover 'inwardly of said edge thereof and 35 through the corresponding piece of material inwardly of the side edges of the second-mentioned portion of the actuating member; to provide a separable fastener of the general character described wherein the ends of the locking members that are 40 secured to the pieces of material have undercut grooves, and the flanges on the first-mentioned portion of said actuating member have turned edges slidable in said grooves; and to obtain other advantages and results as will be brought out by the following description.

Specifically describing the embodiment of the invention illustrated in Figures 1 to 3, inclusive, Z0 the fastener is shown as including two strips or base portions I of suitable material, for example fabric tape, which have their edges 2 in opposed relation in substantially the same plane. Along the edge 2 of each tape I is attached a series of locking members or fastener elements 3 to cooperate or interlock with the series of locking members or fastener elements on the other tape. Each series of locking members includes a plurality of members or fastener elements 4 arranged in S04/spaced relation longitudinally of the corresponding edge 2 and each having one end, hereinafter called the root or attaching end, bifurcated and embracing the edge 2, as at 5. Preferably the edge 2 is reenforced to provide alongitudinal rib 'or protuberance 6 for ensuring a secure grip of the root ends of the locking members upon the tape. The other or interlocking ends I of the locking members project beyond the corresponding edges 2 and each have at one edge a protuberance 8 and at the opposite edge a correspondingly shaped socket 9. The locking members of one series are arranged in alternate relation to the locking members of the other series, so that the protuberances 8 of one series of .locking members may enter the sockets 9 of the other series. The construction so far described is old and well known, and no claim to novelty is made thereon.

.For actuating the locking members of one series toward and from the locking members of the other series to cause engagement and disengagement of the locking members, an actuating member I0 is slidably mounted over the locking members. This actuating member includes two spaced and parallel portions II and I2 which overlie the locking members at opposite sides of the tapes I and form part of the diverging channels which serve to guide the fastener elements into and out ,fof interlocking engagement in progressive order f/ as the slider moves along the tapes or stringers and the single channel into which the dlverging channels merge and in which the fastener elements are in interlocked condition, as clearly shown in Figure 3 of the drawing. One portion, in the present instance the portion II, has side 165 flanges I3 engaging the root ends of the locking members for inuencing the two series of locking members toward each other. The portions I I and I2 are connected at one end by a tie portion Ill which is located between the outer ends of the diverging channels and between which and the side flanges I3 the locking members may pass, so that the slide may actuate the two series of locking members apart from each other. The actuating member so far generally described is also old and wellknown.

In accordance with the invention, the portion or wing I2 of the actuating member has a flat4 under surface and is composed of a substantially -nels between the side anges I3 and the Width of the rectangular section being l substantially smaller than the width-of the single channel so that the side edges I5 of the portion I2 of the actuating member lie between the ends of the l5 locking members II, as shown in Figures 2 and 3, and do not hook over or engage the root extremi- ...`-.ties of the locking members.

This construction of the actuating member enables the accomplishment of another object of 20 my invention, which is to provide an improved cover for the locking members at one side of the tapes I. As shown in Figures 2 and 3, this cover comprises strips I B of suitable material, for example fabric, each of which is applied to one 25 side of one tape I in overlying relation to the corresponding locking members and with one edge I1 disposed approximately coincident with the projecting ends of the locking members 4. This cover strip is fastened to the corresponding 30 tape I closely adjacent the edge of the tape andV at points intermediate the endsv of the locking members so that fastening means sha-libe disposed as nearly as possible to the free edge of the cover strip to prevent the strip from folding 35 backwardly in such a manner as to expose the locking members and to ensure that the edge of the cover strip shall neatly meet or contact with the edge of the cover strip on the other tape when the locking members are engaged, as shown in 40 the lower portion of Figure 2. As shown on the drawing, this fastening means includes stitching which comprises stitches I8 disposed between each two adjacent locking members and connected by stitches I9 extending longitudinally 45 of the tape, said stitches passing through both the cover strip and the correspondingtape close to the root ends of the locking members. Thel stitches I8 and I9 are preferably continuous.

The side edges I5 of the portion I2 of the actu- 50 ating member lie between the switches I8 and the projecting ends of the locking members and beneath the cover strips, as shown in Figures 2 and 3. For sliding the actuating member, the portion I2 thereof may have a substantially tri- 55 angular stud or projection 2U extending outwardly from the portion I2 between the edges I1 of the cover strips, and a suitable finger-piece 2I may be secured to said stud so that by' gripping said finger-piece, th'e actuating member may be slid 60 in either direction over the locking members. As shown in Figs. 1, 2, 5, 'l and 10, the stud 20 is located on that section of the portion or wingA I2 of the actuating member which forms part of the diverging channels and within the area de- 65 ned by the V-shaped spread between the edges Il of those portions of the cover strips which overlie the wing I2. AAs is seen more clearly in Figs. 2 and '1, the cross-sectional area of the stud I2 is substantially `smaller than the area of such 70 V-shaped spread, the narrowest part or apex of the stud being Vdisposed adjacently to the apex of` the V-shaped spread.

Withthis construction, it will be observed that the cover strips I6 entirely cover the locking 75 members whensaid members are engaged, and the edges I'I of the cover strips neatly and tightly contact with each other. There is little possibility of the edge portions of the cover strips folding backwardly due to the fastening means I8, I9 being located close to said edges of the strips. Furthermore, the portion I2 of the .actuating member except' the stud 20 and finger-piece 2| is concealed by the cover strips. The triangular shape of the stud 20 prevents the stud from rubbing against-the edges I'I of the cover strips. and the portion I2 being beneath the cover strips does not tend to wear or discolor the cover strips, as is the case with known types of fasteners where the actuating member encloses or slides over the cover strips. Also, by terminating the side edges I5 of the portion I2 of the actuating member intermediate the ends of th-locking members, it is possible to stitch or otherwise fasten the cover strips close to the root ends of the lock-ing members so that the edges A of a garment may be secured to the tapes close to the locking members.

A modification of the invention is shown ln Figures 5 and 6 of the drawing, where the root ends of the locking members are provided with undercut grooves 22 and the edges of the flanges I3 have turned in portions 23 slidable in said grooves 22. This provides a more secure hold of the actuating member upon the locking members.

Another modification of the invention is shown in Figures 7 and 8 of the drawing, where the cover for the locking members is provided by the edges 24 of a garment. 'I'he edges of the garment may be secured to the tapes I by stitches 25 and 26 corresponding respectively to the stitches I8 and I9 hereinbefore described. This construction is particularly advantageous in that only one line of stitching is necessary for securing the garment to the tape and to form a cover strip by the edge of the garment, and the edges of the garment are brought close together so as to entirely conceal the tape and thereby avoid the diculty of matching the tape with the garment as where the tape is interposed between the edges of the garment, as shown in Figures 1 to 3, inclusive.

Another modification of the invention is shown in Figure 9 of the drawing, where the edge of a garment B is secured between the cover strip 21 and the tape I by the same line of stitches corresponding to the stitches I8 and I9 of Figure 2.

'I'his enables the edge of the garment to be located against the rootends of the locking members, and the surface of the fastener and the garment are in substantially the same plane so as to avoid the formation of ridges and grooves between the edge of the garment and the root ends of the locking members, such as shown in Figure 3.

It will be observed that inall forms of the invention, the actuating member is light in weight and small, so as to provide a minimum of bulk and weight in the fastener, and the outer side of the actuating member is practically entirely covered and concealed by the cover strips. As shown, preferably the edge portions of the portion I2 of the actuating member are beveled at 28 so as to prevent raising of the cover strip from the locking members during manipulation of the actuating member, the portion I2 operating somewhat as a plow.

While I have shown and described my invention as embodied in several forms, it should be understood that this is primarily for the purpose of illustrating the principles of the invention and that the details of construction of the parts may be modified and changed by those skilled'in the art without departing from the spirit or scope of the invention.
