' ROLLER SKATE j "Appiiation mediteren 19, islz'fff `seriai''irolfifzepttu'.

My rinvention relates 'to improvements in roller skates.

One of the objects of my invention is to provide a novel automat-ic braking mechanism Vfor a roller skate, which is simple, cheap,y dnrabie, strong,-not liable to get out o'forder, which is easily operable7 which is so arranged i Vand disposed as ,to not be liable to catch the clothino b'. or canse theoperator to be tripped,

and which` is efficient operation.

Myinvention provides further novel adjustable meansV forattacliment ofthe brake A,operating means to, the 'leg of the operator.

The novel features of my' .invention are hereinafter fully described and claimed In the acco'n'ipanying drawing, which illustrates the preferred.embodiment of my inifention,

y F ig. `l is a side'elevation of .a roller' VSkate provided ywith ,my improvement. v F ig. QUis rearelevation of thelsaine.
