SWIMMING-SHOE.

Specification of Letters Patent.

Patented Jan. 2,1912:

Application filed March 30, 191i. Serial No. 617,924.

This invention relates to swimming shoes -and the object of the invention is to provide neath the a novel device of this character which comprises a receiving member for the foot having a rigid sole and a pair of wings pivotally mounted longitudinally of the sole and adapted to spread upon the operative stroke of the 'foot and to fold upon the inoperative stroke of the foot, thereby offering little resistance in the inoperative stroke and increasing the displacement of water upon the operative stroke thus facilitating the swimming operation.

A further object of the invention is to provide novel means for securing the sole to the foot of the wearer, such means also forming attaching means for a pivot rod besole and to which the wings are secured for operative action.

A further object of the invention is to pivot the wings to the rod in a novel man'- ner and to provide means for limiting the spreading o the wings A still further objectis to provide novel means for limitingthe movement of the wings to a folding position, such means serving the double function of providing .for the attachment of sprin for normally holdin the wings in their extended 9os1- tion,-t1us increasing the resistance 0 ered by returning the wings to such ositionindependent of their action upon tie water.

The invention consists of certain other combinations and arrangements of parts, as will be hereinafter more fully described and clearly specified in the appended claims.

In the drawings :-Figure 1 is a side elevation of my improved swimming shoe.

Fig. 2 is an end elevation of the shoe looka ing toward the toe.

Fig. 3 is an underside view of the shoe with the wings in an extended position, one of the wings .veing broken away to show the means for securingthe rod to the underside of the sole. Fig. 4 is asectional view taken on the hue.

attached rod and also showing the sole and the means for limiting the movements of. the

w in s.

Referring to the drawings In detail, there is shown a sole member 1 which is constructed preferably of wood and has its toe portion extended upward as shown at '2 to conform to the foot of the wearer and also having a heel member 3 for retaining the foot in position. Straps 4 are secured to the heel retaining member 3 nd are adjusta'bly connected by the usual buckle and perforations as shown at 5 to permit adjustment to different persons, said strap 4 which is provided with the buckle having a shield strip (5 extending forwardly therefrom so as to ev'enly distribute the pressure upon the foot at the instep, such portions being preferabl the leather strips 7 which form securing means, in connection with the heel member 3 which also extends beneath the sole 1. for a rod 8 which is disposed centrally and longitudinally of the sole 1 and projects lwyond the toe and heel thereof as is clearly shown in the drawmgs.

It is very obvious that the sole and attachlng means are in the form of a sandal and are thus capable of being readily at-.

tached to the feet butwhen in position will be positively held thereon and against accidental removal, it being apparent that the rod 8 may also be secured to the'sole by metallic clips 9 if desired and as more clearly shown in Fig. 5 of the drawings, The oppositely disposed wings 10 are provided with perforated ears 11 upon their inner edges which pivotally engage the rodS so that said wings may have proper movement in spreading and folding when movcd upon their operative and inoperative strokes and I have preferably shown two of such cars secured to one of the wings for receiving a single ear carried by the other wing. Each of'the cars 11 is reduced to form the attaching rings 12 thus providing shoulders 13 at each side thereof for a. purpose to be hereinafter made apparent.

In order to limit themovcmcnts of'thc wings in their spreading and folding positions. l provide a series of lugs '14 which arc extended in opposite directions as shown in soft leather; Extending over the strip 6 and beneath the'sole 1 are Figs. 3 and 4: of the drawings beneath the sole 1 so that as the wings are moved to a spreaded position upon the operative stroke, said wings will engage the projections and thus arrest the movement thereof. In order to limit the movement of the win 5 in their folded position, lugs 15 are provided upon the rod 8 so as to limit the movement of the wings less than 45 as shown-in dotted lines in Fig. 2 of the drawings. This is accomplished b enga ement of said lugs 15 with the shoul ers 1.3 ormed upon the ears lland in orderto further assist in limiting such movement, a central collar 16 is secured to the rod 8 and provided with a dove-tailed extension 17 which is engaged by the wings. Apertured projections 18 are also secured to the undersides of the wings 10 through which the outer ends of coiled springs 19 are secured by set screws 20 or otherwise, the inner ends of the springs being secured to the collar 16 so that said wings will be normally held in an open position. The sprin are capable of adjustment to regulate t e tension of the springs by the provision of the set screws 20 and it will be seen that these springs 19 normally tend to ex tend the win s and thus assist in their movement upon t e operative stroke independent of the action of the water. From the foregoing description it will be apparent that the relative displacement made and the resistance offered, are advantageously increased to facilitate the swimming operation and as the parts of the shoe which are constructed of heavy-material are such as to be buoyed up by the sole member the tendency of the shoe to sink in the water is revented and the weight thereof diminished, thus offering no resistance in swimming. By reason of the stop members employed, the movements of the wings in their extended and folded position is greatly facilitated and also assisted by the coiled springs connecting the wings to its pivotal rod.

It will also be apparent that the apertured projections '18 abut the undersurface of the sole 1 when the wings are moved to an extended position, thus holding the wings in a common plane and preventing engagement of the swings l.) with the sole,
