L. M. FRIEDMANN COMBINATION ICE AND ROLLER SKATE 2 Sheets-Sheet 2 Filed Nov. 22, 1939 Inventor Zazalsfl firz dmaizn Attorneys Patented July 23, 1940 UNITED STATES PATENT OFFICE COMBINATION ICE AND ROLLER SKATE Louis M. Friedmann, Chicago, 111. Application November 22, 1929, Serial No. 305,715

' 3 Claims.

This invention relates to skates, and has for the primary object the provision of a device of this character which will combine in a unit a roller skate and an ice skate either of which may be easily and quickly brought into use and. which consists of a minimum number of parts and will be compact, durable and may be manufactured and sold at a low cost and will be easily adjusted to different size shoes and may be detachably secured to a shoe or permanently attached thereto if desired.

With these and other objects in View, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation illustrating a skate constructed in accordance with my invention and showing the same arranged for roller skating.

Figure 2 is a bottom plan view illustrating the same.

Figure 3 is a side elevation illustrating the unit combining the roller and runner construction.

Figure 4 is a vertical sectional view illustrating the skate arranged for ice skating.

Figure 5 is a top plan view illustrating the skate.

Figure 6 is a transverse sectional view taken on the line 6-6 of Figure 4.

Figure '7 is a detail sectional view taken on the line 'l--'! of Figure 5.

Referring in detail to the drawings, the numeral 5 indicates the platform of a skate including a toe plate 6 and heel plate 1 having a heel flange 8 to which is connected an ankle strap 9. The heel and toe plates are adjustably connected by a tie plate Ill, the latter having slots ll through which rivets or like fasteners l2 carried by said heel and toe plates. extend whereby the latter may be adjusted toward and from each other for the purpose of fitting shoes of different sizes. Adjustable clamps l3 are provided on the toe plate to engage with opposite sides of the sole of a shoe and are of a conventional construction. The toe plate at the forward end thereof is provided with a fixed toe-engaging clamp [4. Feed nuts l5 are secured to the toe and heel plates and depend therefrom. One of the feed nuts has a right hand thread while the other feed nut has a left hand feed thread. An adjusting rod l6 having feed threads matching the feed threads of the nuts is threaded into the latter and projects rearwardly of the heel plate and equipped with wrench-engaging faces I! whereby the adjusting rod may be rotated in opposite directions forthe purpose of adjusting the toe and heel plates toward and from eachother. r

An elongated box-like mounting I8 is secured to the under face of the connecting plate l0 and the length thereof is somewhat shorter than the length of the skate platform and includes opposed depending converging walls IS. The purpose of the mounting I8 is to removably receive a combined roller and ice skate unit 20 and is provided at one end thereof with opposed stop flanges 2|. The unit 20 may be slid into the. mounting I9 from one end of the latter and abut the stop flanges and be retained against sliding movement by a removable pin 22 extending through both the mounting and the unit.

The unit includes a body composed of opposed elongated plates 23 each including angularly related portions 24 and 25. The portions 24 of the plates diverge toward their upper edges -while the portions 25 of the plates diverge toward the lower edges. The plates 23 are conheated by rigid arms 26 which form an integral part of an ice skate runner 21. The arms 26 are formed on the portions 25 of the plates 23 while the portions 24 of said plates carry journalsv 28 for rollers 29 arranged one opposite the other and in alignment with each other.

The unit 20 thus constructed may be readily adapted or positioned in the mounting so that the ice skate runner 21 may be positioned for use, as shown in Figure 4, with the rollers confined within the mounting or the unit may be reversed so that the rollers will be in operative position with the ice skate runner positioned thereabove and within the mounting.

Thus it will be seen that a skate has been provided which can be conveniently and quickly converted either for ice skating or roller skating and when employed in the latter-named manner presents a skate of the two-roller type.

While I have described and shown the invention with the unit 20 as being composed of boththe rollers and the ice skate runner, it is to be understood that units may be constructed wherein certain units will include the rollers and the other units include the ice skate runners so that either type of unit may be readily adapted to the mounting of the skate as desired for the different kinds of skates, that is, roller skating or ice skating. Further, it is to be understood that while the present invention has been shown as quickly detachablev from a shoe through minor alterations the platform may be permanently fixed to the sole and heel of a skating shoe.
