E. G. DE FESTENBURG ET AL ROLLER BALL SKATE Filed Feb. 4, 1926 Feb.

are.

nMrLE GERARD DEYFESTENBURG AND ARTHUR GERARD on FnsrENBURaor new YORK,

ROLLER BALL sKArn Application filed February The invention relates to improvements in rolling ball skates and has for its object to provide a novel form of rotatable members in which the bearing is made upon the sur face of the said members instead of at the axis thereof as is ordinarily the case.

A further object is a frame adapted to be supported on the said rotatable members and having cushioned extremities which may be used as a means for propulsion, or retardation as required.

The skate is further provided with means of attachment for the rolller casings of such form as to permit of the rivet heads being below the surface of the foot plate.

These and other objects will be more clearly described in the following specifica tion and illustrated in the drawings, in which:

Fig. 1 shows a top view of the skate with the locations of the rollers indicated thereon.

Fig. 2 shows a vertical section on the line 22 of Fig. 1.

Fig. 3 shows a vertical cross sectionv on the line 33 of Fig.1.

Fig. 4 shows an enlarged section of a bearing casing and detail of manner of attachment to the skate frame.

Fig. 5 shows a fragmentary view of the toe of the skate with portion of shoe thereon.

Fig. 6 shows another form of bearing casing.

Fig. 7 shows a form of the invention in which the roller members are placed in line front and rear, and the skate frames designed for the right and left foot respectively.

The component parts of the device are as follows:

A frame 10 having side members as shown at 11, toe clamps as shown at 12, and heel retainer 13; is provided with recessed members as shown at 14, 15 etc., to which are" secured the bearing casings as shown at 16 and 17 by means of the sockets as shown at 18 and the rivets 19. Steel balls of varying sizes as shown at 20, 21, etc., rest Within the said bearing casing and are retained by means of the shoulders as shown at 22. Resting within the casing above described are rolling members of spherical form as shown at 23.

It is obvious that this construction reduces friction to 'a minimum in the bearin and .4, 1926. Serial No. 85,899.

,Cnshion members as shown at 27 and 28 are secured to the frame 10 at the toe and heel thereof and provide means for propulsion when the foot is inclined so as to bring one of the said cushions in contact with the pavement. Retardation may be obtained in a similar manner; preferably using the heel cushion.

The heelretainer 13 is provided with suitable straps and buckles and also with a metal reinforcement as shown at 29. A slot 30, serves to hold a toe strap when desired.

Additional perforations as shown at 31 and 32 are provided to permit of shifting the position of therear roller when desired.

In the form of. bearing casing shown in Fig. 6 ofthe drawings; the balls are all of one size and are retained by the curved rim 33.

In the skate as illustrated in Fig. 7 the frames 10 are shaped for the right and left 2 foot respectively and the roller members are placed in line from front to rear; the general construction is as before shown.

The device as illustrated and described herewith, not only presents a new and novel form of construction, but permits, when in use, of movements which are not possible with roller skates of conventional design.

While we have above described the pre ferred form, construction and arrangement of theseveral elements employed, it will be understood that the device is, nevertheless, susceptible of considerable modification therein, and we therefore reserve the privilege of resorting to all such changes as may be fairly emibodied within the spirit and scope'of the invention as claimed.

Having thus described our invention,

what'we claim as new and desire to secure by Letters Patent, is as follows:

1. In a rolling ball skate, a frame, downward and inwardly inclined side members thereon, bearing caslngs secured to thesaid frame, a plurality of balls in the said cas- 'ings and spherical rotating members resting whole to a shoe or like article.

2. In a rolling ball skate, a frame having downturned sides and with recessed portions I in the race of the said frame, and secured thereto by means of socket members and V rivets, bearing cases having therein a plurality of balls of varying sizes, and resting against the said balls and retained Within the said casing, spherical rotating members, cushions on the front and the rear extremities of the said frame and means to change the position of one rotatable member to another location on the said itrame, clamps and straps for the attachment of the device to a shoe.

In testimony whereof We have affixed our signatures.

Elv'llLE GERARD de FESTENBURG. ARTHUR GERARD de FEST-ENBURG.
