SWIMMING- SHOE.
Applicatio filed. September s, 1926. Serial 110,155,065.
I The invention is a device that may be at tached to'the soles of shoes which will operate to provide a greater bearing surface to assist pedal propulsion. f r p The object of the invention is to provide a mechanical device that may be attached to,
the feet of a swimmer which will automatically operate to multiply the bearing area of the soles of the feet.
Another object of the invention is to provide a simple and efiicient device for increasing the propelling surface of a swimmers feet.
A further object of the invention. is to provide means for attaching a pair of propelling which will increase the swimmers propelling power. 7
With these ends in viewthe invention embodies the upper portionof a shoe having an aluminum frame representing the sole and propeller blades pivotally supported within the said frame. 7
vention will appear from the following de scription taken in connection with the drawings, wherein 1 Figure 1 is a side view of the device. -'Figure 2 is a sectional plan of with the upper plateremoved.
Figure 3 is a cross section through the frame on line 3-3 of Figure 1.
Figure 1 is a view looking toward the. under side of the device showing the. blades in the open position, as they would appear in use. p
In the drawings the device is shown as it would be made, wherein numeral 1 indicates the shoe, numeral 2 the frame and numeral 3 the blades. Y
The shoe 1 may be of any suitabletype or design and may be'made of any suitable ma: terial. It is attached to the upper plate 4 of the frame 2 by rivets or-screws 5, around the edgesas shown in Figure 3. The plate 4 A further object of the invention is to pro-' 'ing them and still'another may be in the 10- Other features and advantages of the in-' I cation of thepivot point as itisunderstood the frame inay also be of any suitable design, however it is preferable to have it correspond to the shapeof a foot as shown and provided with openings 6 as shown in Figure .3 to reduce the weight. This plate is attachedto a lower plate? by posts 8 and 9.at the toe and a post 10 at the heel. The propeller blades lland 12 arepivotally attached to the post 10, as shown, and each blade is held in the closed position independentlyby springs 13 and-14 which are attached to the sides of the blades by screws 15 and 16 and to the frame through pins 17 and 18. The plate 7 is provided with a stop 19 which will engagethe side of the blade 12 as the blade reaches the closed position, and the upper plate 4 is provided with a pin QOwhich extends downward and will engage the side of the blade 11 when it reaches the closed position as shown in Figure2.
The curvatureof the blades is shown in Figure 3 and it will be observed that as the'device is moved through the water one blade will move outward in one direction and the other outward in the other direction to the respective positions shown in Figure 4. i The under side of'the plate 7 may be provided with lugs 21 which may be of any suit-* able resilient material.
It is understood that changes may be made changes may be in the design or arrangement of the propelling blades, another may be in the v I use of a different type of frame for support that the blades maybe pivoted at any suitable point. I r
The construction will be readily understood from the foregoing description. To
' use the device it may be placed upon the'feet as described and it will be observed that as Having thus fully described the invention what. I claim as new and desire to secure by Letters Patent, is:
1'. Ina device of the class described a pair of blades pivotally supported at one end and adaptable to swing outward and to fold with onebehind the other, and means for attaching them to the soles of the feet.
2. In a device of the class described a pair of blades pivotally supported at one end and adaptable to swing outward and to told with one behind the other, and means for attaching the blades to the soles of the feet, said blades being of such a curvature that as they are forced through the water in one direction they will spread outward and as they are drawn through the water in the opposite d rection they will return to their normal positions with one behind the other.
3. In a device of the class described, a shoe, a frame attached to the said shoe, blades pivotally mounted; in the said frame, said blades being pivotally mounted at their ends and adaptable to swing outward and to move inward with one behind the other, means for resiliently. holding the blades in the said frame and means for limiting the movement otally mounted'in thesaid frame, said'blades being pivotally mounted at their ends and" adaptable to swing outward and to move inward with one behind the other, means for resiliently holding the blades in the said frame and means for limiting the movement of the said blades, said blades being ofsuch a curvature that as they are forced through the water in one direction they will spread outward and as they are drawn through lillu water in the opposite direction they will return to their normal positions. In testimony whereof I aifix my signature. KARLOSCAR FREDRICK .IACOBSEN;
