20 Claims.

My present invention relates to means for adjustably fastening two articles or two parts of the .same article, i. e., fastening devices which consist of two elements which are adapted to be plurality of different relative positions. More particularly, my invention relates to fasteners of the class described, in which one of the elements (constituting a track) is substantially flexible and the other element (constituting a slider or locking member) is adapted to be locked thereto at rality of different positions.

One object of the present invention is to pro-l vide a track of so flexible a character that it maybe firmly fixed in the face of a belt, garter, suspendel or other leather or fabric article without diminishing the normal flexibility of such an article to a harmful or substantial extent. Another object is to provide a slider which is adapted to travel longitudinally of such a track for the purposev of obtaining different degrees of adjustment or tensioning, to be locked to said track at any predetermined point, and to be unlocked therefrom at will for further movement along said track or even for complete removal therefrom. Another object is to provide said track with metallic elements for the purpose of positively engaging said slider when in locked position and for the purpose of avoiding abrasion or other injury to the non-metallic parts of the member to which said elements are affixed, without sacrificing the flexible character of such member.

Other objects are to provide a'device of the class described which is readily, conveniently and economically fabricated and assembled, may be readily applied to a wide variety of articles in common use, may be used to hold the parts of such articles in overlapping relation, may be attractive in appearance and may replace devices heretofore employed for the same general purpose but which fail to accomplish some of the objects above described.

The' devices of the present invention avoid or overcomethese disadvantages of the devices of' the prior art and possess other advantages in construction, in operation and in use which will be, in part, pointed out in detail hereinafter and will in part be obvious to those skilled in the art to which the present invention relates.

l In the accompanying specification I shall'describe, and in the annexed drawing show, several illustrative embodiments of the present invention. It is, however, to be clearly understood that my invention is not limited to the specific any one of a plu-l 1927. Application Serial No. 704,032

Fig. 15 is a similar view of a modified form of .L flexible supporting element.

Referring now to the aforesaid illustrative einu bodiments of the present invention, and with par- 105 ticular reference to the drawing illustrating. the same, I employ in said embodiments a flexible supporting member, preferably in the form of a tape made of fabric or other suitable exible edge view showing said embodimaterial. This tape may either be a sinj'le tape 110 f of composite tapes shown attaching operation to whichthe engaging elements of the present invention may be suitably directly secured, as by riveting, clipping or the like, or may be in the form of' a composite tape consisting of a mainsupporting tape and an auxiliary supporting tape to the latter Aof which the engaging elements of the present invention may be similarly suitably secured, or else it may be in the form of a pseudocomposite ,tape made by suitably folding a single width of tape so as to provide a substantially central engaging element supporting portion.

I may, for example, employ the type of fiexible supporting member illustrated in the drawing and there generally designated by reference character 10 andcomprising the main supporting tape member 11 and the auxiliary supporting tape member 12. The auxiliary supporting tape member 12 is preferably of lesser width than the main supporting tape member l1 and is preferably attached thereto, for example substantially centrally thereof, by one or more lines of stitching 13. It may here be stated that the auxiliary tape member 12 may be attached to the main tape member 1l either before or after the engagingelements have been applied thereto. Usually the is carried out before such engaging elements are applied to the auxiliary tape member 12. l

In place of the composite tape shown in detail in Fig. 14 of the drawing, I may employ the types in Fig. 15 of the drawing and there generally indicated by reference character 10'. As there illustrated I employ a plurality of main tape portions 11' to which the auxiliary tape portion 12 may be suitably secured by means of the lines of stitching 13 and 13". It will be noted that the auxiliary tape 4portion l2' is itself folded over so as to' provide the lower inwardly turned tape portions 14' and 14" through which, as well as through the central portion 15' of the auxiliary tape portion 12', the lines of stitching 13' and 13" pass.

In other words, the flexible supporting member comprises what may be termed a main body portion, such as the main tape member 11 in Fig. 14 of the drawing, or the cooperating main tape members 11' and 11" in Fig. 15 of the drawing, and an engaging element supporting portion, for example, the auxiliary tape member 12 in Fig. 14 of the drawing or the auxiliary tape member 12' in Fig. 15 of the drawing. It will also be seen that the engaging-element supporting portion is located substantially centrally of the main body portion of the flexible supporting member. By that I mean that the engaging-element supporting portion is so positioned lwith relation to the main body portion that it is equidistant from each of the side edges of the main body portion. However, such engaging-element supporting portion may be located at either or both margins of the flexible supporting member, as desired.

I provide the flexible supporting member with a plurality, or series of engaging elements, so called because they are intended to engage, and accordingly to be engaged by, the slidable locking and unlocking' 'member or operating means described in detail later inthis specification. I

prefer that the series of engaging elements here' generally designated byreference character 20, shall be articulated, that is, I prefer that the series of engaging elements shall be so arranged as not substantially to diminish the flexible character of the flexible supporting member. To some extent of' course such flexibility is reduced, but the reduction in flexibility should preferably not -as defined in the appended claims, may be used for the purposes of the present invention, I may, for example, employ the type of engaging elements shown in Figs. 1 to 8, inclusive, of the drawing and comprising, for example, a series of clips 21 having the central relatively narrow portions 22 and the substantially hexagonal end portions 23. These latter should be of a size sufflcient to permit their end marginal portions 23 to be clippedl or bent under the free edges of the engaging-element supporting portions 12, in Fig. 14 of the drawing, or 12', in Fig. 15 of the drawing. By free edges are meant the vlaterally projecting flanges of the track or tape 12 or 12 Awhich result from the fact that the same is connected to the main tape portion 11 only along a central longitudinal line or lines intermediate of such edges, as shown in the drawing.

It will be noted that between each pair of engaging elements 21 there is provided a substantially hexagonal or other space 24 which provides convenient means for receiving the operative element or member of the slidable locking and Yunfor the locking means described later in this speciiication. It may here be stated, however, thatv instead of a space 24, a perforation may be employed or other means utilized for bringing about the desired result, allv `within the spirit of the present invention as defined in the appended claims. It may here further be stated that the shape of the engaging element 21 may be varied within a wide range, and the same may be provided'with projections or hooks or other means for suitably engaging the operating element or member oi' the locking and unlocking means of the present invention, without departing from the spirit thereof It will be noted also that between each pair of`clipped under end portions 23' of the engaging elements 21, there is a substantially triangular space 24. The provision of the spaces 24 and 24', or their equivalents, serves to increase the flexibility of the series of what may be termed articulated engaging elements 21. It may here further be stated that while, as shown in Figs. 1 to 8, inclusive, of the drawing the engaging elements 2l are virtually in contact along the edges of the engaging-element supporting portion 12, they may be spaced from each other without coming into contact. However, either arrangement may be employed, depending on the particular specific result had in mind.

The series 20 of engaging elements 21 may be applied to a particular portion of the flexible supporting member 10 which may constitute, as already indicated, either a belt, garter, a portion vof a pair of Suspenders, or the like. Associated whether the same is a belt, garter, pair of sus-I penders or the like, may readily be effected.

I prefer that the means 30 shall be freely movable in one direction along the series 20 of enof track for the slidable means 30. I prefer also that in its opposite direction o1' movement along the series 20 .of engaging-'elements21 the `slidable means 30 shall be such as normally to resist movementin such opposite direction by reason of the engagement of the operating member or element of'the slidable means 30 with one or more of the engaging elements 21 particularly within one of the spaces 24 of the series 20 of en,- gaging elements 21. I prefer also that the slidable operating means 30 shall be provided with means to release or remove the operating member or element from the space 24 or its equivalent so as to permit the free sliding movement of the slidable means 30 inisaid opposite direction, in order `to permit the convenient adjustment in length of the device.

While a Wide variety of slidable means 30 may be employed, constructed in dilerent sizes, all within the spirit of the present invention as de ned in the appended claims, Irmay utilize the construction illustrated more particularly in Figs. 9 to 13, inclusive, of the drawing and comprising a main body portion 31 provided on its undei' surface with the channel portions 32 for receiving the marginal edges of the engaging elements 21 carried by the engaging-element supporting tape 12 and for receiving the flanges of tape 12. The slidable means 30 are further provided with the portion 33, which may be but is not necessarily a spring portion having the transversely turned portion 33', the inner end of which provides the locking element or member of the slidable means 30 of the present invention. The member 33 may pass into and be received by the slot 31' in the main body portion 31. The portion 33 is provided with the lugs orears 33" provided with the apertures or perforations 33"', themain body portion 31 being likewise provided with the apertures or perforations 31". The perforations 31" and 33"' are provided in order to permit the ready attachment of the slidable member 30 to the other portionof the flexible supporting member 10 or its equivalent.

I prefer that the portions 31, 32, 33 and 33' shall be made of a single strip .of metal, preferably of spring metal. I prefer also that the relation of the parts 31 and 33 shall be such that, due to the spring action of the part v33, the locking projection 33 shall normally extend through the slot 31' and thus tend toextend into one ofthe spaces 24. I provide means, generally designated by reference character 34, for overcoming this normal spring tendency of the locking portion 33" to enter into and be positioned securely within one `of the spaces 24. While various means may be employed for this purpose, I prefer to use the means illustrated in the drawing and comprising a main body portion 35 pivoted, as at 36, by means of a pin or rivet which passes through the portions 31 and 33 and which has the serrated or otherwise suitably shaped projecting tab or other manipulating member 37, all as more clearly shown in Figs. 9 and 11 of the drawing.

In order to provide means for overcoming the spring tension of the member 33 with respect to the member 31 so as to lift the locking projection 33' out of the particular space 24 inwhich said locking projection may at the' time be engaged, I provide the main body portion 35 of the means 34 with the substantially wedge-shaped transversely disposed portion 34 so positioned that, upon the rotation of the member 34 about the pivot 36 in one direction, a portion of the wedge-shaped member 34 will be forced inwardl'y between ,the vmembers 31 and 33, 'thus to spread the same apart and thus to lift out of the space 24. In its opposite direction of rotation., the wedge-shaped portion 34' will be lmoved outwardly from between the members 31l and 33, thus permitting the member-33 carrying the locking projection 33' to resume its normal position in one of the spaces 24.v

It may here be stated that due to the spring tendency of the members 31 and 33 to come together, the means 34 will be restored to normalI position without any positive rotational movement of suchmeans by the person using the device. It mayhere further be stated that the shape-of the locking portion 33 is such, asv by Y rendering the same curved or hook-shaped, as

clearly shown in the drawing, that is one'direction of movement of the slidable memberBO, the

locking projection 33 will pass freely with a slid- V`fing contact lover the engaging elements 21, while the locking porinithe opposite direction of itsmovement, the

slidable means 30 will normally tend to' be locked with the curved or hook-shaped lockingprojection 33' in one of the spaces 24. This normal tendency, due, in this instance, to the spring nature of the members 31 and 33, may, as already indicated above, be overcome by the suitable manipulation of the means 34 in the manner already suggested above. f

'I'his completes the description of the aforesaid illustrative embodiment of the present invention. The construction of said embodiment will, it is believed, be sufiiciently clear from the foregoing description. Likewise, the manner of assembling said embodiment will, it is believed, be simimannerof applying said embodiment and of operating the same will, it is believed,I be suciently clear from the `foregoing description but may be briefly summarized as follows:

Assuming that the main and auxiliary tape portions 11 and 12, for example, or 11.', 11" and 12', as the case may be, have been sewn together or otherwise suitably attached to each other, the engaging elements 21 may now be applied tothe engaging-element supporting portion 12 or 12', as the-case may be, by clipping under the end portions 23 of such engaging elements, thus lproviding the series of spaces 24 on one side of the exible supporting device and the two series of spaces 24 on the other side of such exible supporting device. As already stated, the engaging elements 21 may be in Contact at their marginal portions or may be spaced so as to clear each other. In any event, the armored tape will also be quite flexible and 'the engaging elements will provide a track for guiding the slidable operating member.

The tape 10 carrying the series of engaging elements 2i) maybe sold as such for application to the diierent devices with which it is to be used or may be attached directly by the manufacturer to such devices. Such attachment may be by afixing the tape 10 bearing the track upon the surface of an article to which the device is to be applied, a fragment of such article being curately increasing or diminishingthe length of to lengthen the article.

in overlapped relation. It may here be stated that I provide a tapered-member .21' in the nature of an engaging'element adjacent the receiving end of the'device sothat' thefsame may readily be threaded into't'he corresponding channel members 32 -of the"sli dable"operatihg -member30. 'At the 'bya portion of said-flexible supporting member,

other1e`nd of the series 20 of' engaging elements 21Imay-provideg-the locking clip 2l" which will prevent the slidableoperating member 30 andthe flexible portion of the member to which it isl attachedv from being operated too far.

- As already indicated above, the supporting member .lOand the series 20 'of engaging elements 21 carried thereby maybe attached, as by'stitching or riveting, for example, `to one portion of the article with which the device of the present invention is to be used,.for example, a belt, garter, pair of Suspenders or like article. Either carried by 'another portion of the article or o n a separate but cooperating supporting member is carried the slidable operatingv member 30 which may be suitlably riveted or'otherwise securely attached to the member 'carrying the same. It is to'be understood that this invention operates in precisely the same manner-'whether the parts to which the track and slider are respectively attached are parts of the same article or are separatearticles intended for adjustable attachment through the mediumof-the device. Where the claims Ihereinafter set forth speak of adjusting the effective length of a `flexible member or a portion of said flexible supporting member or equivalent phrases, I' mean to include instances Where the track and slider of my'devic'c are attached to parts of otherwise separate articles for adjustable connection with 'each other, as wellas cases wlere these parts, asin abelt, are themselves otherwise united. e A f In adjusting the length of the article the channels 32 of the slidable operatingmember 30 are threaded over the tapered element 2l' and thus onto the series ,20 of engaging elements 21. vThe desired adjustment may readily Abe effected in view of the shape of the locking portion 33' which permits the free sliding movement'of the slidable member 30 along the series 20 of engaging elements 21 in a direction to shorten the article. Once this adjustment has been'effected any leilort ,to lengthen the article willA normally be resisted by the engagement of the locking portion 33 in one ,of the spaces 24. This normal locking tendency may be overcome by the rotation ofthe member 34 in the manner already described above, whereupon the slidable member 30 may be moved along the series 20 of engaging elements 21 Inany desired position of the parts,'the spring action of the members 31 and 33 will act to maintain the device in its adjusted position against any tendency to lengthen the same except when `the member 34 is' operated to permit the desired lengthening action.

This completes the description ofthe mode of operation and of use of the aforesaid illustrative embodiment of the present invention. It will be noted that the device is simple in' construction, and may be readily, conveniently and economically fabricated and assembled. In use, the device is characterized bythe wide range'of usefulness and the wide variety of articles to which it may successfully be applied for conveniently and acsuch articles and maintaining such articles in their adjusted position -as to length.y Other advantages and superiorities of the devices of 'the present invention will readily occur'to those g flexible member comprising `a flexible supporting member `and a seriesy of individualstops carried said stops presenting a track, in combination with a slidable member carried by anothern portion V4of said. flexible supporting Amember and adapted to slide over the tracky presentedby said `series .of stops for selective engagement with the same.; v
