Patented Feb. 14, 1939 2,147,571 SLIDER FOR SLDE FASTENERS Alfred E. Carlile, Meadville, Pa., assignor to Talon, Inc., a corporation of Pennsylvania Application December 12, 1935, Serial No. 54,096 Renewed July 13, 1938 3 Claims.
'I'he lug of the sliderwill press into the garment and make the location of the slider apparent even though it is concealed behind a flap.
One of the objects of my invention is to provide an improved slider which has a minimum over-all thickness and at the same time, has
means for conveniently operating the same,
A more specic object of the invention is to provide a slider with a pull tab hinged to the slider in such a way that it may be swung up over the slider for easy operation, or swung to one side of the slider where it does not increase the over-al1 thickness of the slider and at the same time, if desired, the slider may be operated from the side.
In the accompanying drawing I have shown vfor purposes of illustration three embodiments which my invention may assume in practice. In this drawing: n
Fig. 1 is a plan view of a portion of a slide fastener having my improved slider mounted thereon; y
Fig. 2 is a perspective view of Aa slider showing a slightly modified form of pull tab; Fig. 3 is a cross-section on line 3 3 of Fig. 1; and
Figni is a perspective view showing the modified construction.
My invention is applicable to any known type of slide fastener and the one illustrated is well known and widely used. It will therefore not be described in detail. It comprises generally a pair of flexible tapes 5, 6 having corded edges 1. Attached to the corded edges in uniformly spaced relation are cooperating rows of fastener elements 8. 'I'he slider is mounted to slide along these fastener elements and has upper and lower flanged wings 9, Illrespectively, s0 as to guide the elements on both` sides of the tapes. 'I'he upper wing ofthe slider is made somewhat thicker than the lower wing but its upper surface is flat and smooth. A pair of bearing recesses Il are formed in opposite ends of the upper wing and a pull tab I2 has arms, I3, I4 whose ends are turned in to provide pivots or journals fitting in the recesses II. Preferably the pull tab has a knurled flat portion l5 of substantial area so that it can be easily gripped by the user. The pull tab is so designed that there will be the 5 opening I6 between the arms I3, I4 which opening is of approximately the size and shape of one side of the slider to permit the pull tab to swing around to the side of the slider. While the garment .is in use the pull tab will ordinarily lie 10 flat in the plane of the slider as illustrated in the full line positions of Figs. 1 and 2. In this position it will not penetrate into the material of the garment and interfere with pressing operations.
If desired this tab may be gripped from the side 15 to operate the slider but preferably it will be lifted to the dotted line position indicated in Fig. 2. If desired also the pull tab may be swung to the dotted line position indicated in Fig. 1 when not in use.
In Fig. 2 the knurled portion is extended around one end of the slider as shown at I'Lf In the modied form shown in Fig. 4 the upper wing I8 of the slider is made of the usual thickness and the bearing recesses I9, 20 are provided 25 by suitably deforming the metal. The upward projections required for this purpose will not seriously interfere with the appearance of the article to which the fastener is applied and will not interfere with the pressing operation.
While I have shown and described in this application three embodiments which my invention may assume in practice, it will be understood that these embodiments are merely for the purposes of illustration and description and that var- 35 ious other forms may be devised within the scope of my invention as defined in the appended claims.
What I claim as my invention is: 1. A slider for slide fasteners of the class described including upper and lower wings. the top 40 wing having a substantially flat outer surface, a pull member hinged to the top wing to swing about an axis extending longitudinally of the slider and fastener, the bearing `means which connects the pull to the slider being formed in the 45,
extends upwardly in line with the center line of the slider when the pull is swung upwardly.
3. A slider for slide fasteners of the class described including upper and lower wings in substantially parallel relation with a channel' between them for receiving the fastener elements of a slide fastener, a pull member pivotally connected to the top wing to swlngabout an axis
