The present invention relates to Swimming devices and has for its object to provide an improvement of the construction described and shown in my U. S. Patent #1340592, dated May 25th, 1920.

The invention consists in the novel construction, arrangement and combination of parts as will be hereinafter fully described and defined in the appended claims.

In the accompanying drawing in'which similar reference characters denote corresponding parts, Figure 1 is a side elevation of my device showing its attachment to a shoe; Fig. 2 is a perspective view of thedevice; Fig. 3 is a section on line 3-3 of Fig. 1, Fig. 3 is a front view of a detail; and Fig. l is a perspective view of a somewhat modified form of thedevice.

My device is adapted to be used principally in connection with a shoe such as originally used for bathing but may with slight modifications be made applicable to the hands. 7

When used in connection with shoes, the latter, as will be hereinafter described, are. equipped with means for the attachment of the device.

The device proper, of whichoneis used for each foot, consists of a paddle shaped rigid blade a which is so dimensioned that it will, when applied tothe foot of the swim- V Specification of Letters Patent.

The modified blade '6 shown in Fig. 4 is identical in construction with that l shown in Fig. 2, except that the mouth or recess 6 is elongated to permit the blade to be applied to the foot in a somewhat inclined posiper part of the shoe. r
