Fig. l of the 'drawings show, partly in section and partly in top plan View, the two rows of fastener members of a form of construction of a sliding clasp fastener for connecting two fabric edges i and 2 which lie in a common plane and abut along a straight line -y. I', l" and 2', 2" are the usual edge reinforcements o'n the two fabric edges (see also for example Fig. l). The members of the one row fixed on the fabric' edge i are designated by A with a subreference, for example A1, A2, A3 and the members of the other row on the fabric edge 2 are designated by B with a subreference, for example B1, Bz, B3 The fastener the usual manner with raised portions and recesses for their mutual engagement.
A perspective view of a form of construction of a fastener member is illustrated in Fig. 2. a.
and i: are its side surfaces, c lts head and d is its foot surface; e and f are its upper side edges and g and h its lower side edges.
The fabric edges do not always lie in a common plane and the abutment of the fabric edges is not always along a straight line; Sometimes the fabric edges lie in a common plane but they abut along an irregular or regular curve, in the latter instance, for 'example along the arc of. a circle. In some cases the fabric edges lie in the wall of a cylinder or cone and abut along a cone or cylinder circle or along a spacial curve. In the case of Fig. 3, which is hereinafter described, the fabric edges l, 2 lie forv example in the same plane and their abutment line :c-y extends along the portion .r-z in an arc about the centre 3 and in the portion z-y in an arc about the centre d. 'in the case of the diagram shown in Fig. 5 the two fabric edges lie in the wall of a cylinder curved about the axis 56, whereas the abutment line :l5-1l is a plane circle, and in the case of the diagram shownl in Fig. 6 the two fabric edges i, 2 lie in the wall of a cone, the axis of which is ii-, and which has its apex at 8'. The abutment line ar-y is again a'plane circle.
The following expressions will be used in the descriptionz- Rectllineal sliding clasp fastener isa sliding members are provided in.
clasp fastener for fabric edges which lie in a plane and abut along a straight line.
Curve sliding clasp fastener is a sliding clasp fastener for fabric edges abutting along a curve irrespective of whether the fabric edges lie in 5 a plane or in a curved surface.
Plane circle sliding clasp fastener is a slid.- ing clasp fastener for fabric edges lying in a plane and abutting along the arc of a circle.
Cylinder circle sliding clasp fastener is a sliding clasp fastener for fabric edges lying in the wall of a circular cylinder and abutting along the circumference of a circle. s
vCone circle sliding clasp fastener is a sliding clasp fastener for fabricV edges lying in the wall of a cone and abutting along the circumference of a circle.
Curved sliding clasp fasteners are advantageous for many purposes, for example for overshoes forA ladies and gentlemen, curtains for 20 sleeping car windows, purses, hat boxes, tires and hoods for motor cars, protecting covers for radi-- ators of motor cars, overcoats, for detachably connecting the fur collar or coat lining and the like.
along a curve thel known rectilineal sliding clasp fasteners were hitherto employed with the modification that the members are arranged on the outer fabric edge at a greater distance apart than o on the inner fabric edge, the outer fabric edge being, however, mostly stretched or provided with incisions and the inner fabric edge drawn together or overlapped. Consequently when the fabric edges abutting along a curve are interconnected by a. rectilineal sliding clasp fastener,
-the members only interlock imperfectly, and the more imperfect the sharper the curve is. Moreover, the slider which is the case of rectilineal sliding clasp fasteners is usually rigid and sym- 40 metrical relative to its longitudinal axis, tends to force the members out of the path, when the rectilineal fastener is employed for connecting fab- 'ric edges abutting'along a curve, with the result For the connection of fabricl edges-abutting`25- cylinder circle fastener.

Fig. 20 is a mediumy longitudinal section through the slider on plane 20-20 of Fig. 19 in developed state.
In Figs. 3 and 7 to 9 as in Fig. 1 the two fabric edges are designated by I and 2 and the members by A1, A2, A3 and B1, B2, B: respectively whereas :c-y (see Fig. 3) is the curve along which the fabric edges I, 2 abut.
The new shape of the fastener members according to the invention can be seen from the considerably enlarged perspective View shown in Fig. 7. If :v -y' is a small portion of the abutment curve .'t-w, this curve portion :1f-y will have a certaincurvature centre m. If the curve portion a:'y' is short enough it can be regarded as a straight line` and a plane can be imagined through it and the centre m, which plane is the curvature plane of the curve at the point in question. If a vertical line S-S is imagined erected on this plane in the centre of curvature m, the planes of the two side surfaces (a and b in Fig. 2) of the fastenerk members coordinated to the corresponding curve portion in question will, according to the invention join in this line s-s.
The conditions are particularly simple when Iaxis 5-6 (Fig. 8).
the fabric edges ,lie in one plane along their entire length and their abutment curve forms anarc of a circle. Thus, forexample in the case of Fig. 3, the abutment curve lies in the planeof the drawings, and the projections of the side surfacesA a, b of the members on to the planeof the drawings extend in the actual direction of the radius of the circle, which means that these projections converge, as faras the members'. co ordinated'to the arc .'c--z are concerned, towards the centre 3 and, `as far as the members coordinated to the arc z-y are concerned, towards the centre 4. Consequently, the members A and B (Fig. 3) coordinated to the arc :r--z taper in the direction of the arrow I and the members A curve with varying curvature, the Amembers A fixed on the fabric edge I, (and the same applies also for the members B fixed on the fabric edge 2) are of different shape, whereas in the case of plane circle sliding clasp fasteners all the members 'A fixed on the fabric edge I (and also all the members B fixed on the fabric edge 2) are of uniform shape. the members A are different from the members B.
Fig. 8 shows on a considerably enlarged scale the cross section through a cylinder circle sliding clasp fastener, in which the fabric edges 1ying according toFig. 5 in the wall of a cylinder abut along the arc .icy of a circle. -In the case of a plane circle sliding clasp fastener, as shown in Fig. 7, the projections of the side edges e--j on lthe one hand and g-h (see Fig. 2) on thev other hand of each member converge in the line s-s; compared herewith all the ^yedges e,- f, g, and h in the form of construction shown in Fig. 8 are parallel to one another and to the cylinder Also in this instance all the members A and also all the members B are uniform, whereas the members A are the negative of ihe members B and consequently different. thererom.
. Fig. 9 shows a considerably enlarged perspective view of a-cross section through a cone circle sliding clasp fastener. Again the projections of the two side surfaces a and b of each member converge, in this instance towards the axis 1 8. Further the surfaces c and d also taper in the direction towards the apex of the cone, as the projections of the side edges c and f of all members converge towards the common cone apex 8 (respectively the projections of the edges g and h towards the cone apex 8"). In this instance all the members A are again different from the members B, but all the members Aare alike and all the members B are alike.
Figs. 10 to 17 show different forms of construction of the fastener slides. In all the figures 9 designates ythe head plate, I0 the foot plate `of the slider, I I its web connecting the two plates on one end, I2 the handle serving for shifting the slider and I5 its guide wedge.
If both fabric edges I and 2 lie in one plane along their entire length,l the abutment curve is In both instances, however.,
however not regular but irregularly curved and .edge extensions I4 of the two slider plates 9,
I0 and leave free between them the gap necessary for the passage of the fabric edges. The guide wedge I5 arranged between the two slider plates is not rigidly connected with the plates but is movable relatively thereto, so that it can shift in lateral direction. In the example illustrated the guide wedge I 5 is carried by two arms I6 an upper arm and a lower arm, these two arms I6 beingv each connected with the two slider plates 9 and i by a pin I1 arranged in the same axial plane and serving as pivot axle. The arrangement may, however, be such, as shown in Figs. 10a to 12a that the guide wedge I carries onl its upper end and on its lower end a pin-shaped extension I9, and the two pin-shaped 'extensions each engage in a guide slot 20 in the corresponding slider plates 9, I0, these slots being curved in an arc around an imaginary axis I'l corresponding to the axis of the two pins i1 of the slider shown in Figs. to 12. In such a construction, as well that shown in Figs. 10 to 12 as that shown in Figs. 10a to 12a, the fastener slider can fit snugly to the curved path of the two rows of members of the sliding clasp fastener.
Figs. 13 to 15 show a slider for a plane circle sliding clasp fastener. The slider corresponds to the rigid slider generally employed for rectilineal sliding clasp fasteners only with the difference that its longitudinal axis n-n is curved in the same arc as the abutment curve of the two fabric edges. The side walls I8 of the slider are formed by bent edge portions of the two slider plates 9, l0. The guide wedge I5 is rigidly connected with these plates.
Figs. 16 and 17 show a rigid slider for a cylinder circle sliding clasp fastener. In this case the two slider plates 9, I0 are bent to cylinder surfaces concentric to the cylinder surface of the fabric edges. I8 are the rigid side walls of the slider.
For a cone sliding clasp fastener the slider shown in Figs. 10 to 12 with elastic side walls and a guide cone freely movable from the medium position towards the one or other longitudinal side of the slider may be employed. For a cone circle clasp fastener in which the cloth edges meet along a circle a rigid slider as shown in Figs. 18 to 20 may be employed. In this instance similar to Fig. 17 the two plates 9, I0 are curved, the curves corresponding, however, this time to conical surfaces which are concentric to the conical surface of the cloth edges. When iiatly spread out in a plane, the two plates, as shown in Fig. 20., possess a shape similar to that shown in Fig. 14; the radius-of the circle, according to which the middle line n n of the corresponding slider plate is curved, then corresponds to the generatrix (side length) of that cone, according to which this slider plate is bent andthe base circle of which isA the cone circle coinciding with the line n n.
