3nventor N052 S7747/7A/V Mam (Ittomegs Patented Nov. 18, 1952 UNITED STATES PATENT 1 OFFICE 2 Claims.

My present invention relates to improvements in shoes, more especially of the type having a releasable securing strap across the instep or top of the foot. When a shoe of this type has been drawn over the foot, it requires but a single operation of fastening the strap to the side of the shoe. Heretofore it has not been found practicable to provide an adjustable fastener for the end portion of the strap. It is the object of this invention to overcome this drawback by employing a fastener of a type previously invented by me and which I have adapted to its present use.

Further objects of my invention and the advantages thereof will be apparent as the description proceeds. The invention will be best understood by reference to the following detailed description taken with the annexed drawin s in which Fig. 1 is a plan view of a shoe containing a preferred embodiment;

Fig. 2 is a side view of the same, showing one fastener element in place;

Fig. 3 is an enlarged view in section along line 3-3 of Fig. 1;

Fig. 12 is a view in section along line l2l2 of Fig. 7;

Fig. 13 is a view along line I3-l3 of Fig. 7;

Fig. 14 is a view in longitudinal section showing a further modification; and

Fig. 15 is a view in cross-section of a further form of track in place on the shoe.

In Fig. l, the shoe, denoted generally by l, is of the type having a strap 2 over the instep which is releasably secured to a side portion 3 of the shoe. The top 4 of the shoe terminates in the usual tongue 5.

As seen particularly in Fig. 3, the end portion of strap 2 has attached thereto a slider, denoted generally by A, which engages and is adjustably secured on a track denoted B. Thus the slider is secured to the strap 2 while the track B is secured to the portion 3 of the shoe. The slider A comprises a body portion 1 of generally G-shaped cross-section which, by virtue of this shape, is adapted to be secured to track B by engaging beneath same as shown in Fig. 4. Body portion 1 has upstanding ears 8, 8 which pivotally support a clamp or locking element denoted generally by 9. This element 9 comprises a tab portion Hi and a cam portion II and is further provided with trunnions l2 which engage apertures in the ears 8, 8, as best seen in Fig. 4. The material forming said ears is taken from the body portion 1, thereby forming an aperture in said body portion, denoted 13, to enable the cam or locking portion II to come in contact with the track B, as in Figs. 12 and 13, or as shown in Fig. 3 to contact a separate locking plate (4, Fig. 6. which is provided with corrugations l5 and is held floatingly in place by a notch IS on either side, to accommodate the ears 8. The corrugations I5 register with corrugations in the track to be described, whereas the top of the plate I4 is engaged by the cam II. The use of the plate [4 provides for gripping the track to be described over a plurality of corrugations rather than between a single pair of same, if this plate were not used. (A suitable aperture must be cut in the strap 2 as best seen in Fig. 3.) As shown in Figures 1, 3 and 4, an apertured facing plate I? is placed over the slider with the tab In projecting through the aperture, the plate I! being secured in place by tabs or fingers I8 which pass through the material of the strap 2 and are bent over in clamping engagement as shown in Fig. 4.

The track B in the form shown in Figs. 2 and 3 consists of a metallic hollow member or shell 20 which encloses a small metallic securing rod or wire 2| which passes through the length of said shell, and is then caused to project therefrom through the material of the side 3 and then to be turned over as indicated at 21a, thus clamping the top end of the shell to the shoe piece 3. Similarly at the lower end the rod 2| is caused to make a U-bend 2lb. Preferably the material of the bends 2| a and 2") is covered by the shoe lining 22. Shell 20 has corrugations 20 stamped or otherwise formed therein for engagement with either the corrugations of the floating plate I4 or the end of the clamping member 9. The end of the track B adjacent the top of the instep is enlarged as at 23, thus providing a stop for the slider which is threaded thereon at the opposite end 24. Alternatively, the shell 20 and the inner rod 2| may be made integral if desired.

Figs. 7, 8, 9, 10, 11 and 12 show a further modification. Here the track B consists of a fabric strip 25 which by means of stitching 26 and the folds 21 therearound has formed therein a ridge upon which are secured staples 28 at regular intervals. Figs., 8 and 11. The track so formed is attached to the-fshoe by means'or th r-alone strip 25I"whih preferably is s'eciir'ed betwen the outer layer 29 of the shoe and the lining 30 by parallel rows of stitching, as shown best in Fig. 11. A stop 3| is disposed at the end of thetrack at the top of the instep, as in the previously described embodiment. The slider"A""'in"this embodiment may comprise a crosspiece32- (Fig. 13) by virtue of which the end of the strap 2' may be joined. As shown the strap 2"isai5ertured to receive the cro'sspiece 32. At the region 'of the"aperture; the'str-ap is turned 180' andthe lo'op thus formed is secured by means ofstitch- I ing" 33. The slider A is similar "in all respects to sliderA'except "that it lacks the outer casing In Fig. '14-"a'track B"" is employed of plastic material having'corrugations 34 formed at-the outer surface threotasshown. This track is 1 secure to- 'the' shoe by means of stitching'GS. Otherwise the operation and construction of the -device'i's similar to the form'shown in Fig; 7.

Similarly, in Fig. '15- a track 36 is employed,

formed" of a plastic impregnated fa-bric" secured by stitching 31. ThepIaStic'tracksof Figs. 14, 'are further shown-in my 'Patent No. 2,437,765.

--In use the strap 2or- 2'- is of s uflicient length 56 as toenable the slider to-be threaded over the far*end of the track B. {This threading operation maybe done'preferablyb'efore thesh'oe is ous strip of material attached to said shoe proper,
