' ROLLER FOR SKATES.

SPECIFICATION forming ,.To all whom it may concern:

Be it known that I, EDWARD FRANoIs BAL- LOU, of Marlborough, in the county of MiddleseX, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Rollers for Skates, and I do hereby declare the same to be described in the following specification and represeiitedin the accompanying drawings, of which Figure 1 is a side view; Fig. 2, an edge elevation; Fig. 3, a transverse, and Fig. 4 a longitudinal, section of a skate-roller of my improved kind.

The improved roller has a groove formed within it at and around its periphery, which It is found in practlce that a skate-roller so constructed is preferable to one without cork in it, as it makes very much less noise in rerevolved to better advantage.

volving on a floor, wears it less, and can be Besides, it is not so liable to slip lateral1y,'and thereby cause a skater to fall down while suddenly turning about in skating.

I am aware that bicycle-wheels usually have elastic tires of rubber, and that carriagewheels have had elastic tires extendiugacross their periphery, and therefore I make no claim to such. Nor do I claim in rollerskates rubber springs or any other device adapted as shown or described in the United States Patent No. 243,761, or in that entitled Reissue N0. 7 ,345. In myskate-roller the cork does not extend entirely acrossithe periphery, but only partially across it, such cork being flanked by or depressed between bearing-surfaces of such periphery, which prevent it while in use from being contracted so as to be injured or.

broken.

' Itherefore claimas a new or improved manufacture A skate-roller grooved peripherically and having cork arranged in the groove, and flanked by bearingsurfaces or parts of the periphery, substantially as set forth.
