Definitions
- This invention pertains to fastening devices of theclass commonly'known as separable, interlocking fasteners of which the patent to Judson, No. 557,207, dated March 31, 1896 may be cited as an early instance.
- Such' devices' are commonly employed for closing 'gaps or Openings in garments, for eX- ample, sweaters, coats, leggings, .overshoes-
- Judson patent above referred to that if the cam elements of the slider are of such yslope as to insure ease of operation,
- the slider may slip lengthwise of the closed fastener in response to stresses tending to open the gap, thus allowing the gap to Open inadvertently, unless some means be provided for positively holding the slider at the limit of its -travel with the gap closed.
- Judson patent referred to a crude form of retaining means comprising loops adapted to engage appropriate pins was provided for the purpose and since the yJudson patent, many other retaining devices have 'been proposed.
- a slider which in most respects is of a usual type, has an openingin its front wing in which a frictionmember is loosely fitted and the pull tab has an offset or cam at its inner side so arranged that'when the pull 33 hangs downwardly from one end of the slider, the Cam or offset foroes the friction member inwardly through the Opening so that it presses against the fastener elements, thus preventing accidental movement of the slider, but in this prior construction, if for any reason the slider be inverted so that the pull tab hangs downwardly from the other end of the slider, the cam element of the pull tab is no longer effective to actuate the friction member.
- the gap is closed by movement of the slider upwardly, while in other instances, the gap is closed by downward movement of the slider. Since the pull tab tends to hang downwardly in either case when released byv the operator it has previously been-necessary in constructing sliders of the type just referred to. to design the pull and retaining means with particular reference to the direcf tion of movement'of the slider in closing the gap, and thus a garment manufacturer who used fasteners, some of which closed by up- ,ward and others by downward movement of the slider, has been obliged to provide himself with sliders of two distinct forms.
- I provide a slider having a very simple, inexpensive and reliable form of pull controlled retaining means which will retain the slider in adjusted position with the pull depending whether the slider be intended for movement upwardly or downwardly in closing the gap.

SLIDER FOR FASTENERS Filed Oct. 16, 1929 Patented Cet. 14, 1930 UNIIED vSTATES PATENT OFFICE GEORGE E. PRE'NTICE, OF BERLIN, CONNECTICUT, AssIGNOR To G. E. PRENTICE MANU- EACTURING COMPANY, OE NEW BRITAIN, CONNECTICUT, A CORPORATION OE CON- .N EGTICUT -SLIDER FOR FASTENERS Applicationkled October 16, 1929. Serial No. 399,954.
This invention pertains to fastening devices of theclass commonly'known as separable, interlocking fasteners of which the patent to Judson, No. 557,207, dated March 31, 1896 may be cited as an early instance. Such' devices' are commonly employed for closing 'gaps or Openings in garments, for eX- ample, sweaters, coats, leggings, .overshoes- However, it has been recognized since as 'early at least as the Judson patent above referred to, that if the cam elements of the slider are of such yslope as to insure ease of operation,
the slider may slip lengthwise of the closed fastener in response to stresses tending to open the gap, thus allowing the gap to Open inadvertently, unless some means be provided for positively holding the slider at the limit of its -travel with the gap closed. In the Judson patent referred to, a crude form of retaining means comprising loops adapted to engage appropriate pins was provided for the purpose and since the yJudson patent, many other retaining devices have 'been proposed.
Sincerapidity of actuation is one of the important advantages claimed for fasteners of this type, it is obvious that any retaining means requiring careful manipulation by the operator detracts from the value of the device, and for this reason, attempts have been made to embody the retaining means in the actuating pull or tab in such a way that when the pull or tab is released after actuation of the slider .and allowed to hang vertically down, the slider is automatically retained in position.
In onevery desirable construction known to me, a slider, which in most respects is of a usual type, has an openingin its front wing in which a frictionmember is loosely fitted and the pull tab has an offset or cam at its inner side so arranged that'when the pull 33 hangs downwardly from one end of the slider, the Cam or offset foroes the friction member inwardly through the Opening so that it presses against the fastener elements, thus preventing accidental movement of the slider, but in this prior construction, if for any reason the slider be inverted so that the pull tab hangs downwardly from the other end of the slider, the cam element of the pull tab is no longer effective to actuate the friction member.
However, in some garments or other articles, the gap is closed by movement of the slider upwardly, while in other instances, the gap is closed by downward movement of the slider. Since the pull tab tends to hang downwardly in either case when released byv the operator it has previously been-necessary in constructing sliders of the type just referred to. to design the pull and retaining means with particular reference to the direcf tion of movement'of the slider in closing the gap, and thus a garment manufacturer who used fasteners, some of which closed by up- ,ward and others by downward movement of the slider, has been obliged to provide himself with sliders of two distinct forms.
In accordance with the present invention, I provide a slider having a very simple, inexpensive and reliable form of pull controlled retaining means which will retain the slider in adjusted position with the pull depending whether the slider be intended for movement upwardly or downwardly in closing the gap..
In the accompanying drawings I have illustrated a preferred embodiment of my invention by way of example l In the drawings:

' Fig. 8 is an edge elevation of the friction device completed; and
Fig. 9 is a view similar to- Fig. 3 illustratingI the locking action when the slider occupies the position shown at the lower part of Fig. 4.
Referring to the drawings I will first describe one desirable form of slider provided with a retaining shoe engageable with the fastener elements and will ,then Vdescribe my improved means for actuating the shoe,4
such means being so designed as to permit use of the same v,slider for closing the gap either by upward or downward movement of the slider. Referring partizclxlarly to Figs. 1 to 3, the numerals 1 and esignate tapes or stringers to which the opposed series of fastener elements 3 are respectively connected. While it is usual to furnish fasteners of this kind to the trade in the -form 'of a complete structure comprising the tapes or stringers upon which the series of fastener elements are mounted, it is to be understood that so far as its broader aspects are concerned the present invention is not necessarily limited to the inclusion of these tape members, since it is conceivable that the fastener elements might be applied directly to the edges of the material in which the gap occurs and when in the appended claims the term Stringer is employed, it is to be understood as broadly comprehending an flexible element forming in effect one e ge of the gap to be closed. For convenience in illustration I have shown the fastener` elements 3 as of the type more -fully described for example,
and claimed in the patent to Prentice and Legat No. 1,658,392, dated February 7, 1,928, but it is to be understood that the present invention is not to be limited to such spe.
ciic use but is applicable to fasteners of t other types falling within the general class.
For use in moving the fastener ,elements of the opposed seriesinto operative relationship, I employ a 4slider S which in general may be of a type well known in the art" as, that shown in the patent to Prentice No. 1,677,408, Julyv 17, 1928, al-V though I have here illustrated the slider as of specifically novel form and construction.
united by the neck 6 and having the elongatey guide tongue 7 projecting integrally from the outer end of the wing portion 4a. This elongate guide tongue 7 is provided near its free end with a portion 8 of reduced Width, beyond which the extremity 9 of the tongue again increases in width. The neck 6 is providedat its opposite edges with lintegral tabs' 10 and 11 and it is to be understood that, as usual, in the manufacture of sheet metal sliders, the lateral edges of the wing portions 4a and 5 are bentfinwardly to formsuitable. guide flanges. The blank, as shown in Fig. 5, is bent atfthe junctions of the wing members with the neck so as to bring the wing portions `into substantially parallel relation, and theA guide tongue 7 is then bent to provide the lower 'substantially horizontal portion 12 (Fig. 2), theA substantially vertlcal guide portion 13 which -is parallel to and spaced fromthe ,front surface ofT the wing 4, and the topfmember 14 across the top I or which extendsk rearwardly portion8 of the the slider. The reduce tongue is disposed between the tabs 10 and 11 which are turned upwardlyv and then inwardly as indicated Vin Fig. 1 so as to clamp the end portion of the tongue between them.
VThe front wing 4 is provided with an open-A ing 15 -for the passage of the yfriction shoe 16.
VThis friction shoe is conveniently formed as an integral U-shaped bend ina sheet metal rocker member comprising stiilyA resilient arms 17 and l18. This rocker may be made from a piece of sheet material the divergent of the general shape indicated in Fig. 7 havy A ing the central neck portion 16 of such width that when bent tothe shape shown in F ig. 8 it may pass through `the opening 15. This blank also comprises the end portions 17a and 18" of greater width than the neck and adapted to form the arms 17 and 18. Preferably the outer ends of these arms are forked to provide the retaining fingers 19 which engage the opposite edges of the guide member 13 in order to hold the rocker in vproperly assembled relation to the slider body. The pull or tab 20 is here shown as of a general type commonly employed in sliders of this kind and is preferably made from sheet material of any suitable character.
y present invention relates to improvements upon the slider thus far'described. In accordance with the present invention the tab or pull is preferably of more or less T-shape in edge elevation as shown in Fig. 6. the cross arm of the T being formed by suitably bendmg or swedging the upper edge of the sheet recessed or material forming the bod of the pull. Thus, as shown in this figure, t e pull proper is provided with the oppositely and laterally projecting portions 21 and 22 which collectively form the crossbar of the T-Shaped pull.
The pull is provided with an opening 23 through which the guide member 13 passes,
the guide and opening supportingr the pull pivotally and permitting the pull to be moved from one end to the other of the slider. As indicated in Figs. 2 and 3 the cross bar of the pull is disposed between the front face of the rocker and the rear face of guide 13. When, as shown more particuarly in Fig. 3 the pull is swung outwardly at a substantial angle to the direction of movement of the slider in order to facilitate actuation of the latter, the crossbar comprising the members 21 and 22 moves freely in the space between the guide 13 and the rocker so that the position of the rocker is not effected substantially by the pull, thus permitting the shoe 16 to retreat from the opening 15 and preventing any substantial .pressure of the shoe against l the fastener elements so that the slider can be moved freely in either direction. Assuming that the slider is moved upwardly to close the fastener, as shown at the upper part of Fig. 4, the pull 20, when released by the operator, will hang downwardly from the lower end ofthe guide 13, the weight of the pull tending to swing it to a substantially vertical position. Since the crossbar comprising the members 21 and 22 is of substantial width, the vertically depending pull causes the ends of the bar to contact respectively with the guide 13 and with the lower arm 17 of the rocker, and the crossbar thus acts as a cam for forcing the arm 17 against the wing 4. By reason of the divergent arrangement of the arms 17 and.18 the'end of the arm 18 now bears resiliently against the inner surface of the guide 13 which forms a slightly resilient abutment. and the pressure of the crossbar of the pull against the lower arm 17 causes the shoe 16 to projectv through the opening 1 5 and press forciblyagainst the fastener elements. pushing them against the rear wall 5 of the slider and exerting a frictional drag which effectively prevents accidental movement of the slider. To assure the maintenance of this locking or holding action the pull 20 may be swung rearwardly by pressure of the fingers toward the plane of the wing 4 (with reference to'the pivotal support of the pull upon the guide 13) so that the crossbar, comprising the parts 21 and 22 will assume an inclined position. In thus pressing the pull rearwardly, the rocker arms 17 and 18 as well as the guide 13 may spring slightly, being formed of resilient material,
' and thus when the pull is disposed in its rear- `ward position, as described, the pressure of the parts will so'retain it until itis positively swung forwardly beyond the vertical plane.
Since the crossbar of the pull is substantially symmetrical, that is to say, projects to both sides of the plane of the part 20, the pull will operate in the same way for pressing the friction shoe into operative engagement with the slider elements whether the slider be disposed as shown in Figs. 2 and 3 or whether it be reversed as shown at the lower part of Fig. 4. Thus our improved slider may be used with the same locking or holding effects in closing gaps either by upward or downward movement. For example, in childrens draw leggings, the gap in the body portion is usually closed by a slider which moves upwardly, while the gaps in the legs are closed by sliders which move downwardly. By employing the slider above described, the manufacturer of such a garment may use like sliders both in the body portion and in the legs of the garment, with the assurance that the sliders will remain in gap-closing position indefinitely until positively moved to open the gap.
While I have illustrated certain desirable embodiments of the invention by way of eX- ample, I wish it to be understood that the invention is not to be limited by the arrangements specifically shown and described but is broadly intrusive 'of such modified constructions as fall within the range of equivalency of the appended claims.
