With the gap closed, the ribbon is exl tended, and the runners are widely separated. In such closed relation of the slide-fastener. the loop carrying runner is generally at the upper end of the gap and in actual use however this loop carrying runner has a tendencyv to slide downwardly and thus start to fold the closure ribbon.

consequently opening at least the upper part` of the gap whereby the loop carrying runner ultimately strikes against an adjacent lower runner and thereafter in use both of these runners continue to shift and slide downwardly in respect to the spaced tapes, thus further folding the closure ribbon and consequently the extent of the opening of thegap is increased. To a user of this type of slide fastener, involuntary opening there-` of at times may result in considerable embarrassment. It is therefore the dominating object o of the'invention to provide conveniently controlled positive brake means to prevent accidental or involuntary opening of the slide fastener when in a desired closed relation thereof. Other objects, features, and advantages of the invention will be`betterunderstood from the following detailed description considered in connection with the accompanyingl drawing in which:

Fig. l is a front elevational and broken view m of the slide fastener according to my invention; showing the gap defined by the beaded tapes closed by a ribbon secured to a plurality of runnersnow shown widely separated and further showing the upper runner in a braking relation i in respect to the tapes to prevent. involuntary displacement of the ribbon. n 4

Fig. 9 is a fragmentary portion of a slide iastener of the type shown in Fig. l but illustrating s0 "another form of braking runner.

Fig. ll isa cross sectional view taken on the line lI-il of Fig. 9. Illustrative of the embodiment disclosed thev 16 slide fastener generally designated IB comprises spaced tapes ll each provided with a beaded edge 'i2 and defining an elongated gap i3 adaptedto be closed or opened by auv elongated flexible and foldabie ribbon M fastened to a series of runners 20 or blocks Il each provided with a slot i6 extending'widthwise thereof adapted to receive a looped or folded portion/l1 of the lclosure ribbon il which is arranged in back of the beaded edges I2.

More particularly however each of the bloops i1 25 Fig. l0 is a side view of Fig. 9 and is fixedly retained in a slot il of a respective runner by apointed pin il passed into a longitudi nally disposed opening I! which intersects and communicates with a companion slot i6 and isv `normal thereto. 30

With a loop portion of the closure ribbonrranged in a slot il. a pointed portion of a pin Il is positioned within a companion bore or opening i9. Thereafter pin i9 is forced and moved through bore il until its pointed end penetrates the positioned loop or bend il within the runner. Havingpierced the loop. the pin is further displaced until its outer end is wholly within the runner, for example as shown in Fig. 2. Each f pin Il vfrictionally coacts with a companion bore i! and hence after the pin is properlyset it is completely within `the runner and it cannot be. accidentally displaced. Y

Each runner of the type designated by reference character II embodies side grooves 20 of the type 45 shown which receive and are slidably guided on the beaded edges l2 of the spaced tapes. By the present construction, if one of the runners i5 is slidably displaced in respect to the tapes, the closure ribbon carried by this runner is correspondingly displaced; According to the invention, positive brake means is provided to preclude accidental displacement of the closure ribbon. In this con'- nection, attention is directed to the uppermost runner generally denoted 2i which includes front l and Arearvvv but complementary clamping plate members22and 23, the front clamping member 22 .having depending ribs 24, 25 and 25 forming longitudinally arranged grooves 21 land 23 while the rear clamping plate 231s provided with the spaced ribsv 23, 3l and 3l defining spacedl groovesl einen. t

Interposed betweenthe clamping members 22 and '23 is .the upperend `34 oi' the foldable ribbon I4 which maybe of a suitable cloth. 'I'his end 34 is provided with a perforation 35, which in the assembled relation of thel ribbon and clamping members isin alinement with openings Il of the intermediate ribs 25 and 3l thereof, and threadved opening 31 ofthe collar 39 fixedly and appropriately anchored within the rearlclam'ping" member 23. y

In assembling, .the brake to the ribbon and tapes, the upper end or'terminal 34 of the ribbon I4 is'placed onto-the ribs of they rear clamping member 23. Thereafter beaded edges l2 of the 'tapes are placed on terminal 34 of the ribbon in such fashion that spaced portionof thelatter (Fig. 7) are received in grooves 32 and 33. Subseq`uently threaded shank 40 of the manipulator broadly denoted 4| is inserted into opening 36l of the front clamping member 22, through opening 35 in ribbon i4, through opening 35` in the rear clamping member 23, and thereafter is rotated to interlock 'with threads of the bore 31 of the annular flange 3l of collar 35.

Having positioned shank 40 in respect to the clamping'members and closure ribbon, this shank is upset to form head 42 receivable 'in socket 43 of the fixed collar 39. Shank 45- is threaded as shown and includes an eye 44 swingably and loosely supporting the finger piece member or loop 45' carrying signal or vindicating means '45.` 40

In the assembled relation of the clamping members 22 and 23 beads' I2 of tapes Il are in part conned in the alined grooves`21 and 3,2, and 23 and 3'3, however permitting the clamping members and the ribbon I4 to be bodily and slidably guided longitudinally of the tapes in an' lunclamped relation of the clamping vmembers 22 and 23 .when the'flnger piece loop 45 is dis- .placed' longitudinally of the beaded tapes I i.

For example. in Figs. and 6 the several runners i5 have been brought together to open the 4gap i3. This is accomplished/ by grasping loop 45 (Fig. l) and applying a downward thrust thereto to cause the clutch or brake 2i to movev downwardly. However displacement of thebrake may only take if the clamping members 22 and 23 are set `in an unclamped` relation as indicated in Fig; 6 to first relieve the clamping and frictional pressure from beaded edges of the tape previously imparted thereto by the inner ribbed and grooved faces of. the companion:

complementary clamping members 22 `and 23.

With the brakereleased from the'tape's, the

to the gap, such position can b'e retained uponl rotating loop 45, in a certain direction for causing shank 4I to site direction hence J, 'tion integral and in IOtte. which action causes apodos? i clamping member 23 tofm'ove towards clamping member 22 and thus frictionaliy clamp and bind the ybeaded tapes to prevent accidental or involuntary shifting of the brake in respect to the beaded edges I2 and the shank40 is turned until signal 46of loop 45 faces outwardly indieating to the wearer that the brake is an operative'gripping relation. To releasel gripping action ofthe brake, loop'45 is rotated in an oppomember- 23 to'move awayfrom the clamping member 22.

f As shown in Figs. 1 vand 2', the lower end of the closure ribbon is fastenedvto the lower ends is shifted downwardly, the blocks i 5 are caused to shift downwardly. thus permitting the gap I3 to be opened as indicated in Fig. 5'. To close the gap, control loop .45 for the brakeis grasped and pulled upwardly, thus actuating the run- 1 ners and `the ribbon is extended to partially or fully close gap I3 as desired after which loop 45 is rotated to causethe brake to gripl the tapes.

In'the form according to Figs.,9 to l1 inclusive thel braking runner 50 is of the typey identified by reference character l5 in Fig. 1 however the top 5I thereof is reduced to denne marginal shoulders 52. Extend-ing widthwise of the reduced top 5I is an opening 53'vin which is arranged a fulcrum pin 53 swlngably or pivotally supporting the ends of varms loop generally denoted 55. 'Ihe fulcrum pin 53 of` course has its outer ends upset to prevent removal oi' the arms 54 from this pin,

As shown the arms 54 of the loop closely 'straddie reduced top 5I and each arm includes a cam or pointed projection 55 serving as means to slightly penetrate and wedge tapes il simultaneously against shoulders 52 ci' the or lower part of the braking runner 50'when the loop 55 is moved into a closing relation as shown -in Fig. 9. In such relation the braking runner 5I! is prevented from being accidentally displaced and consequently the ribbon cannot be fully shifted vlongitudinally of tapes.

When itis desired to disengage loop 55 from thetapes, crown 55 of this loop is graspedxand swung away from the beaded tapes il and positioned as shown by the dash and dot lines in Fig. consequently, cams 55 release and become free oi' tapes ii, and vhence the braking vrunner may be displaced to shift the other runners of the slide fastener as well as to open or close the gap defined by the beaded tapes; vIn other aspects, the slide fastener according to Figs. 9-11 inclusive is along the lines of the form according `to Fig. l except that in Fig. 9, .the

upper part of the braking runner 50 has an octagonal contour.

While a certain preferred embodiment of the invention has been illustrated and described, it is to be understood that the invention is not limited thereby but it issusceptible to various changes in form and details Vo f its scope.
