Definitions
- This invention relates to separable fasteners of the slider actuated type and pertains more particularly to a slider for such4 fasteners having improved means for supporting the pull tab and 5 for locking the slider in any desired position of adjustment, such locking means being operative to retain the slider in adjusted position whether the slider be moved upwardly or downwardly, respectively, in closing the gap or opening,
- the pull tab is arranged to swing through an angle of approximately 180 about an axis extending transversely of the slider, and it is necessary to employ a pair of oppositely directed locking devices operative, respectively, at each of the extreme positions of the pull tab, in order properly to hold the slider in adjusted position when the pull tab is arranged at either extremity of its movement.
- the prominently exposed face of the pull tab has frequently been employed as a convenient location for a trade name, the makers name, a patent number, or the like.
- the pull tab is, at diiferent times, disposed in positions substantially 180 apart so that 5.5 opposite sides of the tab may be alternatively exposed to view when the tab is not in use.
- the tab of such a slider is to be ornamented or is to bear distinctive indicia, it becomes substantially necessary to provide the distinctive ornamental appearance or other characteristic at both faces of the tab, which adds to the cost, and in some cases-for example, .
- the tab is ornamented by embossing (which may result in deforming the tab from a at or plain surface), it is lnot possible to make both sides of the tab alike.
- One object of the present invention is to provide a slider capable of use for closing a fastener by upward or downward movement, re-
- a further object is to provide a slider of the double locking type, that is to say, one which may be locked whether the slider be used in closing a fastener by upward or downward movement, respectively, in which a single locking element, if desired, may be employed for locking the slider in adjusted position regardless of whether the pull tab depends toward the neck end-of the slider or toward the opposite end.
- Another object is to provide a double locking construction of simple and efficient type which can be made cheaply, and readily applied to substantially any type of slider body, and which, while durable and ,o

- Fig. 18 is a fragmentary perspective of the pull tab of Fig. 16. l
- the numerals I and 2 indicate the usual iiexible stringers employed in fasteners of this type for supporting the opposed cooperating series of fastener elements 3 and d, respectively.
- These fastener elements may be of any usual construction and are moved into and out of engagement by means of a slider 5, having convergent guide channels for the reception of the respective series of elements.
- the slider body is of the general construction disclosed in the patent to Prentice No. 1,900,949, dated March 14, 1933, but it is to be understood that the presentinvention is applicable to sliders of other specic construction.
- the slider is actuated by'means of a pull tab 6 which, as illustrated in Figs. 1 and 2, is provided with an ornamental front face. ornamentation produced by embossing, engraving, and in other ways is common in the art.
- the slider body as illustrated, comprises the front and rearwings 1 and 8, respectively, united at their upper ends by a neck portion 9 whose lower end, in well known manner, functions as a divider to separate the opposed series of fastener elements as the slider is moved upwardly, and the front wing 'I is furnished with a pair of openings IIJ and II incidental to the striking up of portions of the metal to form bearing lugs I2 and I3 which, in the completed slider, are xed, relatively to each other and to the other parts of the slider body.
- lugs may thus be formed as integral portions of the front wing, it is obvious that they may be provided in any other suitable way, for example, by attaching separate elements to the front wing by solder, brazing, or the like, and in that event the openings I0 and II need not be formed.
- lugs I2 and I3 are provided with aligned openings adapted to receive pintle members Il and I5, respectively, projecting from the opposite ends of a trunnion I6 (Fig. 4e)
- the pull tab 3 is also furnished with a pivot or swivel member I9 (preferably integral with the nger-engaging portion of thek tab) projecting from its upper end, as viewed in'v Figs. 1, 2 and 4.
- the axis of this pivot member extends longitudinally of the tab (that is to say vertically as viewed in Fig. 4) and is substantially within or parallel to the general plane of the pull tab, as illustrated.
- this pivot or swivel member I9 is passed through a diametrical Iopening 20 in the trunnion member I8, and the extreme end of the pivot member is then headed over to form a retaining head 2i (Fig. 2).
- the opening 20 is substantially midway between the ends of the trunnion I6 and is disposed perpendicular to the axis of the trunnion, the latter and in heading over the pivo; or swivel I9, care l is taken to permit freedom of rotation of the pull tab 6 with respect to the trunnion I6 about the axis of pivot or swivel member I9,-the pivot member I 9 turning in the opening 20.
- the latter is assembled with the slider by introducing the pintle members I 4 and I5 into the openings in the tabs I2 and I3, the latter being sprung apart for this purpose or bent up into nal position only after the pintle members have been entered in the bearing openings, thus providing in effect, a knuckle or hinge joint between the trunnion and the slider body, the axis of this hinge joint always extending transversely of the slider body.
- the swivel connection of the pull tab to the trunnion, and the hinge connection of the latter to the slider body provides a species of universal joint between the tab and slider body.
- the front Wing 'I of the slider is furnished with a pair of openings 22 and 23 spaced longitudinally of the slider at opposite sides, respectively, of the horizontal plane of the axis of the trunnion member, and at such a distance from such axis that when the pull tab 6 hangs downwardly away from the neck of the slider in the position of Fig. 2, the locking tooth or element I I may pass through the opening 22 and into locking engagement with the fastener elements. 3 and 4. as illustrated in Fig. 3.
- the locking element II ⁇ may be bent as indicated in Fig. 5 to accommodate it to the position of the openings 22 and 23.
- This capability of the pull tab to have its same face presented forwardly under all conditions of use is especially desirable where the front face of a tab is ornamented, for example,by surface ornamentation, as shown in Figs. 1 and 2, or, for instance, where the forward face of the pull tab SB of the slider 5e (Fig. 15) is provided with an imitation jewel, ornamental enamel, or any other common form of embellishment.
- the present invention avoids the necessity of applying the mark to both faces of the pull tab ii the slider is to b e used for closing the gap in more than one direction.
- a single locking element I1 located substantially on the vertical central plane of the slider, isdesirable, it may, under some circumstances, be preferred to provide two rearwardly projecting tooth members or locking elements on the pull tab, adapted to engage the fastener elements at opposite sides of the central axis of the slider.
- the front wing of the slider 5b is shown as provided with laterally spaced openings i3 and 28h, it being understood that a similar pair of openings (corresponding to the opening 22 of Fig. 2) is arranged symmetricallybelow the axis of the trunnion le.
- the pull tab Sb is furnished with a pairlof retaining elements l'la and Hb adapted simultaneously to passrearwardlythrough one of the pairs of openings in the front wing and to engage the fastener elements of the opposed series at laterally spaced points.
- f' v In Fig. 14 a slightly modified constructionfis illustrated in which the retaining element l1 of the pull tab is widened at its rear or inner end so that instead of entering substantially between adjacent fastener elements of the series, it .presses 'against the forward faces of such elements so as to avoid distortion or displacement of the ele ⁇ ments.
- a modied form of pull tab is disclosed, such as tab Bf, having a pair of laterally directed ears 26 and 21 at its upper end, the tab also being furnished with a ,rear- 'wardly struck portion llf constituting the lock-v ing element.
- the pivot member I9 is independent of the pull tab proper and is provided with a head at 'each end, and'in assembling the parts the ears 26 and 21 are bent downwardly and inwardly so as to -embrace one end portion of the pivot member i9, as illustrated in Fig. 6.
- Figs. '7 and 9 a further modied form of pull tab is illustrated, this tab Si also having laterally projecting ears 28 and 29.
- the pivot member I9bl is separate from the pull end portion. l'l'I which constitutes the .locking 5 element.
- a further modification is illustrated wherein, although the pull tab is arranged to be turned so as always to expose the same face forwardly, -a pair of alternatively acting locking elements is employed instead of the single locking element of the previous constructions.
- the trunnion member ISP isprovided with the pintle members' it and -l and with the transverse bearing opening 20 in the same way as the trimnion I6 above described.
- 'Ihe pull tab tu. is provided with a pivot member i9 in the same wayA as that of Fig.
- this pivot member is disposed in 'the opening 2B of the trunnion memv au ber and headed over at its end vin the same way as that ofthe tab 8.
- the tmnnion member i6 is provided with a pair of locking elements di) and 3l projecting, respectively; in opposite directions and .at substantially right angles to the 25 axis of the opening 2t.
- the front wall of the slider inv this instance is furnished with Alout a single opening 32 (Fig. 13) disposed immediately behind the trunnion I6, and the locking elements 30 and 3i alternatively projected through 30 this opening and into engagement with the fastener'elements, in accordance with the position of the pull tab.
- the pull tab may be swung about the axis of the trunnion ⁇ Iso as to depend, when released,- either from the neck end or the oppo- 35 site end of the slider, in accordance with whether the slider is used for closing a gap by' downward or upward movement, respectively, and in either event, adequate locking action is obtained by the construction disclosed.
- the mount- 40 ing of the -puli tab Sh so as to turn relatively to 'the trunnion i6, it is possible to keep the same face of the pull tab exposed to the front in either of its locking positions in the same way as described with reference to the preceding construc- 45 this ball' or lknob terminates in' a substantially 50.
- a locking element may be desired, this may be provided, vfor example, by striking out a portion of the metal from the pull tab so as to provide a rearwardly projecting pin 'or cam element 35 as in the arrangement of Fig. 55 5, for example.
- the pull tab illustrated in Figs. 16, 17 and 18 may thus be made'from a single piece of metal b y appropriate manipulation.
- the pull-supporting lugs or ears 12a, illa are formed, for example, Aas described with reier- 60 ence to Fig. 2, but in this case they are furnished with spherically curved bearing socket cavities 35e in their adjacent vertical faces, such cavities being conveniently formed by embossing, stamping or other appropriate method.
- These ears 65 are so relatively disposed in the completed slider that the ball 33 of the pull tab is conilned between them,being free to turn in the bearings provided by the opposed cavities in the faces of the lugs.
- 25, I3 are so close 70 plane of the slider body.
- these lugs are furnished withchannels 3B leading forwardly from their respective bearing cavities, and these channels afford clearance for the stem 34 of the tab, after the latter has been swung forwardly to a position substantially at right angles to the plane of the front wing.
- the tab may be turned about a front-to-rear axis in its own plane through substantially 180, and then may be swung down again into a position substantially parallel to the front wing but so as to extend toward. the opposite end of the slider from that toward which it nrst extended.
- This arrangement is advantageous since the pull tab with its pivot means and locking element may be made as a singlerintegral part.

SLIDER FOR FASTENERS .Filed June 10, 1933 Patented Oct. 29, 1935 SLIDER FOR FASTENERS Herman T. Gammons, Natick, Mass., assigner to G. E. Prentice Manufacturing Company, New Britain, Conn., a corporation of Connecticut Application June 10. 1933, Serial No. 675,198
31 Claims. (Cl. 24.205)
This invention relates to separable fasteners of the slider actuated type and pertains more particularly to a slider for such4 fasteners having improved means for supporting the pull tab and 5 for locking the slider in any desired position of adjustment, such locking means being operative to retain the slider in adusted position whether the slider be moved upwardly or downwardly, respectively, in closing the gap or opening,
Sliders provided with so-called double locking devices are in common use in the garment trade, and desirable embodiments of such double locking sliders are disclosed, for example, in the patents to Prentice No. 1,778,338, dated October 14, 1930, and No. 1,890,749, dated December 13, 1932.
In all commercial forms of double locking slider with which I am familiar, the pull tab is arranged to swing through an angle of approximately 180 about an axis extending transversely of the slider, and it is necessary to employ a pair of oppositely directed locking devices operative, respectively, at each of the extreme positions of the pull tab, in order properly to hold the slider in adjusted position when the pull tab is arranged at either extremity of its movement.
However, but one of such locking elements is useful at any one time, and the presence of the forwardly projecting inactive locking element is, in some constructions, detrimental to the appearance of the slider.
Fasteners of the class to which this invention relates are now applied to a great variety of articles in which a neat and ornamental appearance is a desideratum, and in view of this fact manufacturers of such fasteners have made it a common practice to ornament the pull tab, for example, by embossing, engraving, enameling, or
even by in-.setting artificial jewels, or otherwise finishing the front exposed face of the tab. Moreover, where ornamentation is not so particularly desired, the prominently exposed face of the pull tab has frequently been employed as a convenient location for a trade name, the makers name, a patent number, or the like.
, In the more usual type of slider, unprovided with a lock and always closing the fastener by movement in the same direction, the same face Vof the pull tab is always exposed to view when the tab is not in use, but when sliders are designed for use in closing a gap either by upward or downward movement, respectively, and in particular when a double locking type of slider is employed, the pull tab is, at diiferent times, disposed in positions substantially 180 apart so that 5.5 opposite sides of the tab may be alternatively exposed to view when the tab is not in use. Thus when the tab of such a slider is to be ornamented or is to bear distinctive indicia, it becomes substantially necessary to provide the distinctive ornamental appearance or other characteristic at both faces of the tab, which adds to the cost, and in some cases-for example, .where the tab is ornamented by embossing (which may result in deforming the tab from a at or plain surface), it is lnot possible to make both sides of the tab alike.
One object of the present invention is to provide a slider capable of use for closing a fastener by upward or downward movement, re-
spectively, so constructed and arranged that the same face of the pull tab may always be exposed at the front when the tab is not in use. A further object is to provide a slider of the double locking type, that is to say, one which may be locked whether the slider be used in closing a fastener by upward or downward movement, respectively, in which a single locking element, if desired, may be employed for locking the slider in adjusted position regardless of whether the pull tab depends toward the neck end-of the slider or toward the opposite end. Another object is to provide a double locking construction of simple and efficient type which can be made cheaply, and readily applied to substantially any type of slider body, and which, while durable and ,o
reliable in operation, may be made at a relatively low cost.
Other objects and advantages of the invention will be pointed out at greater length in the following description and by rrreference to the accompanying drawing in which certain desirable embodimentsvof the invention are shown by way of example.

Referring to the drawing, the numerals I and 2 indicate the usual iiexible stringers employed in fasteners of this type for supporting the opposed cooperating series of fastener elements 3 and d, respectively. These fastener elements may be of any usual construction and are moved into and out of engagement by means of a slider 5, having convergent guide channels for the reception of the respective series of elements. Ashere shown the slider body is of the general construction disclosed in the patent to Prentice No. 1,900,949, dated March 14, 1933, but it is to be understood that the presentinvention is applicable to sliders of other specic construction.
The slider is actuated by'means of a pull tab 6 which, as illustrated in Figs. 1 and 2, is provided with an ornamental front face. ornamentation produced by embossing, engraving, and in other ways is common in the art.
The slider body, as illustrated, comprises the front and rearwings 1 and 8, respectively, united at their upper ends by a neck portion 9 whose lower end, in well known manner, functions as a divider to separate the opposed series of fastener elements as the slider is moved upwardly, and the front wing 'I is furnished with a pair of openings IIJ and II incidental to the striking up of portions of the metal to form bearing lugs I2 and I3 which, in the completed slider, are xed, relatively to each other and to the other parts of the slider body. While these lugs may thus be formed as integral portions of the front wing, it is obvious that they may be provided in any other suitable way, for example, by attaching separate elements to the front wing by solder, brazing, or the like, and in that event the openings I0 and II need not be formed. 'I'he bearing lugs I2 and I3 are provided with aligned openings adapted to receive pintle members Il and I5, respectively, projecting from the opposite ends of a trunnion I6 (Fig. 4e)
The pull tab 6, as illustrated in Figs. 4 and 5, for example, preferably is` provided with a rearwardly projecting locking element I1 conveniently formed by striking up the metal, thus leaving an with opening I8. Obviously this tongue may be made as a separate part and secured to the pull member, if desired. The pull tab 3 is also furnished with a pivot or swivel member I9 (preferably integral with the nger-engaging portion of thek tab) projecting from its upper end, as viewed in'v Figs. 1, 2 and 4. The axis of this pivot member extends longitudinally of the tab (that is to say vertically as viewed in Fig. 4) and is substantially within or parallel to the general plane of the pull tab, as illustrated. In assembling the parts, this pivot or swivel member I9 is passed through a diametrical Iopening 20 in the trunnion member I8, and the extreme end of the pivot member is then headed over to form a retaining head 2i (Fig. 2). The opening 20 is substantially midway between the ends of the trunnion I6 and is disposed perpendicular to the axis of the trunnion, the latter and in heading over the pivo; or swivel I9, care l is taken to permit freedom of rotation of the pull tab 6 with respect to the trunnion I6 about the axis of pivot or swivel member I9,-the pivot member I 9 turning in the opening 20. l
After the pull tab and trunnion have been assembled, the latter is assembled with the slider by introducing the pintle members I 4 and I5 into the openings in the tabs I2 and I3, the latter being sprung apart for this purpose or bent up into nal position only after the pintle members have been entered in the bearing openings, thus providing in effect, a knuckle or hinge joint between the trunnion and the slider body, the axis of this hinge joint always extending transversely of the slider body. As thus assembled, the swivel connection of the pull tab to the trunnion, and the hinge connection of the latter to the slider body, provides a species of universal joint between the tab and slider body. The front Wing 'I of the slider is furnished with a pair of openings 22 and 23 spaced longitudinally of the slider at opposite sides, respectively, of the horizontal plane of the axis of the trunnion member, and at such a distance from such axis that when the pull tab 6 hangs downwardly away from the neck of the slider in the position of Fig. 2, the locking tooth or element I I may pass through the opening 22 and into locking engagement with the fastener elements. 3 and 4. as illustrated in Fig. 3. The locking element II `may be bent as indicated in Fig. 5 to accommodate it to the position of the openings 22 and 23. The arrangement of parts shown in Fig. 3 is that which they occupy when the slider is tobe used in closing a fastener by upward movement, in which event, at the end of the upward movement, the pull tab is allowed to drop and to hang or depend downwardly (or in a direction away from the neck of the slider and toward the lower end of the latter) 1f it should be desired to employ this slider for closing the fastener by downward movement, it is merely necessary to lift the pull tab substantially to a position substantially perpendicular to the slider wing and then to turn it about the axis oi its pivot member I9, as illustrated in broken lines at 24 (Fig. 3), through substantially 180, whereupon the pull tab maybe brought to the position shown in broken lines at 25 in Fig. 3, in which the tab depends from its axis toward the neck end of the slider, so that its locking element I'I now passes through the opening 23 for locking engagement with the fastener elements. It is thus possibleby the employment of this found in double locking sliders.
pendently of whether the locking element be emarrangement. to use a single locking element for A locking the slider, whether the same be employed ployed lor not, it is possible to keep the same front face of the pull tab always exposed to view, whether the slider be used for closing the gap by upward or downward movement, since, as noted, in swinging the pull tab from the position shown in full lines in Fig. 3 to that shown in broken lines at 2 5 in the same gure, the pull tab is turned through substantially aboutits own pivot member I9 while it is being swung through 180 about the axis of the pintle member I6.
This capability of the pull tab to have its same face presented forwardly under all conditions of use is especially desirable where the front face of a tab is ornamented, for example,by surface ornamentation, as shown in Figs. 1 and 2, or, for instance, where the forward face of the pull tab SB of the slider 5e (Fig. 15) is provided with an imitation jewel, ornamental enamel, or any other common form of embellishment. Moreover, since it is common to use the front face of the pull tab as a convenient location for a trade mark or patent number, the present invention avoids the necessity of applying the mark to both faces of the pull tab ii the slider is to b e used for closing the gap in more than one direction.
While a single locking element I1, located substantially on the vertical central plane of the slider, isdesirable, it may, under some circumstances, be preferred to provide two rearwardly projecting tooth members or locking elements on the pull tab, adapted to engage the fastener elements at opposite sides of the central axis of the slider. Thus in Fig.- 10 the front wing of the slider 5b is shown as provided with laterally spaced openings i3 and 28h, it being understood that a similar pair of openings (corresponding to the opening 22 of Fig. 2) is arranged symmetricallybelow the axis of the trunnion le. In this case the pull tab Sb is furnished with a pairlof retaining elements l'la and Hb adapted simultaneously to passrearwardlythrough one of the pairs of openings in the front wing and to engage the fastener elements of the opposed series at laterally spaced points. f' v In Fig. 14 a slightly modified constructionfis illustrated in which the retaining element l1 of the pull tab is widened at its rear or inner end so that instead of entering substantially between adjacent fastener elements of the series, it .presses 'against the forward faces of such elements so as to avoid distortion or displacement of the ele` ments.
Referring to Figs. 6 and 8, a modied form of pull tab is disclosed, such as tab Bf, having a pair of laterally directed ears 26 and 21 at its upper end, the tab also being furnished with a ,rear- 'wardly struck portion llf constituting the lock-v ing element. In this case the pivot member I9 is independent of the pull tab proper and is provided with a head at 'each end, and'in assembling the parts the ears 26 and 21 are bent downwardly and inwardly so as to -embrace one end portion of the pivot member i9, as illustrated in Fig. 6.
In Figs. '7 and 9 a further modied form of pull tab is illustrated, this tab Si also having laterally projecting ears 28 and 29. In this case also the pivot member I9bl is separate from the pull end portion. l'l'I which constitutes the .locking 5 element.
In Figs. 11, 12 and 13 a further modification is illustrated wherein, although the pull tab is arranged to be turned so as always to expose the same face forwardly, -a pair of alternatively acting locking elements is employed instead of the single locking element of the previous constructions. In this arrangement, as illustrated in Fig. l2, the trunnion member ISP isprovided with the pintle members' it and -l and with the transverse bearing opening 20 in the same way as the trimnion I6 above described. 'Ihe pull tab tu. is provided with a pivot member i9 in the same wayA as that of Fig. 4, and this pivot member is disposed in 'the opening 2B of the trunnion memv au ber and headed over at its end vin the same way as that ofthe tab 8. The tmnnion member i6 is provided with a pair of locking elements di) and 3l projecting, respectively; in opposite directions and .at substantially right angles to the 25 axis of the opening 2t. The front wall of the slider inv this instance is furnished with Alout a single opening 32 (Fig. 13) disposed immediately behind the trunnion I6, and the locking elements 30 and 3i alternatively projected through 30 this opening and into engagement with the fastener'elements, in accordance with the position of the pull tab. The pull tab may be swung about the axis of the trunnion `Iso as to depend, when released,- either from the neck end or the oppo- 35 site end of the slider, in accordance with whether the slider is used for closing a gap by' downward or upward movement, respectively, and in either event, adequate locking action is obtained by the construction disclosed. By reason of the mount- 40 ing of the -puli tab Sh, so as to turn relatively to 'the trunnion i6, it is possible to keep the same face of the pull tab exposed to the front in either of its locking positions in the same way as described with reference to the preceding construc- 45 this ball' or lknob terminates in' a substantially 50. i
The pull-supporting lugs or ears 12a, illa are formed, for example, Aas described with reier- 60 ence to Fig. 2, but in this case they are furnished with spherically curved bearing socket cavities 35e in their adjacent vertical faces, such cavities being conveniently formed by embossing, stamping or other appropriate method. These ears 65 are so relatively disposed in the completed slider that the ball 33 of the pull tab is conilned between them,being free to turn in the bearings provided by the opposed cavities in the faces of the lugs. Preferably, the lugs |25, I3 are so close 70 plane of the slider body. However, these lugs are furnished withchannels 3B leading forwardly from their respective bearing cavities, and these channels afford clearance for the stem 34 of the tab, after the latter has been swung forwardly to a position substantially at right angles to the plane of the front wing. In this position, the tab may be turned about a front-to-rear axis in its own plane through substantially 180, and then may be swung down again into a position substantially parallel to the front wing but so as to extend toward. the opposite end of the slider from that toward which it nrst extended. This arrangement is advantageous since the pull tab with its pivot means and locking element may be made as a singlerintegral part.
While I have herein illustrated certain desirable embodiments of the invention by way of example, it is to be understood that 'changes in size, proportion and relative arrangement of parts, as well as the substitution of materials and equivalents, may all be made without departing from the spirit of the invention as defined in the appended claims.
While I have herein made reference to the upper and lower ends of the slider, and tov upward or downward movement of the pull tab, it is to be understood that all such reference to direction are for convenience in description, and with reference to the illustrations, and are not to be regarded as in any sense limiting the claims to particular positions of the slider when in use.
Likewise when I make reference to the plane of the pull tab, I do not thereby intend .to indicate that the tab is mathematically dat, but merely to facilitate the description of the relation of parts, and to refer to a general and usual formation of the tab in which the finger-engaging portion is transversely broad.
