Arranged on the parts46, 43 respectively of the hangers 33, 34 respectively, are ianged collarsv 6|, 62 respectively whichen'compass the lbolts52, 53 respectively. The spring 59 is interposed between collar 6I and the'part I5 of portion 8- of body part 1. The spring 59 seats onthe ange of collar 6|` and encompasses the part 54' of bolt 52. The spring 6l] is interposed between collar 62 andV the'part I6 ofthe portion I6 of body part'l. 'The spring 59 seats on the flangev of collar 62 and encompasses the part 54 `of bolt 53. The parts 40, 43, and collars 6I, `62 are capable of sliding vertically on the bolts. These latter are fixed relativelyto the said base pieces 26,3I and the said parts I5, I6

by a pair of superimposed nuts 63 secured on the may be termed controllers for the oscillation or a revolving of the. hangers. When elements 66, 61 are employed the structure is for-street skating and the hangers are 'held stationary. When elements 66, 68 are employed the structure is for rinkskating land with the forward hanger capableof being oscillated and the rear hanger held from` oscillation.` When element 68 is solely employed, the structure is for fancy skating and both hangers are capable of oscillating. When elements 66, 61 or elements 66, 68 are employed they couple the hangers together andv also couple them with body part 1. When element 68 is solely employed it couples the hangers together but it does not couple them with the body por- Ition. When elements 66, 68 are employed the l front wheels of theskate may turn to the right or left but the rear wheels are held in aligned relation with body part 1. When it is desired to permit of the front or rear wheels turning to the left or to the right the element 68 is solely employed. When it is desired to keep the front and rear wheels held in aligned relation with body part 1, the elements 66, 61 are employed.

' The element 66 isy of rectangular contour in plan and consists of a plate 69 formed of an upper, forward, horizontally disposed end terminal portion 16 provided with an opening 1I, a lower, horizontally disposed, rear end terminal portion 12 formed with a pair of openings 13 for registry with openings 5I, and an intermediate portion-"14 which inclines downwardly 'from portion 16 to portion 13. When element 66 is employed the portion 16 thereof is detachably secured to the body -part`1 by bolt 64 and nut 65 (Figures l and 2*),

and the portion 14 mounted upon and detachably `2'5 securedto the part 4dr-fof hanger i341by the hold.-

fastV means 15. extending through the aligning openings\5`|,13.

The element' 61 is of rectangular contour in planand consists of avplate 1.6 provided in proximityto the vrear endwith a pair of openingsll for registry with the openings 5| when element 81: is employed; The element plate 1.6L between its `transverse medianand forwardend is provided on its lengthwise median with a slot 11e. When elementA B1 'is employed in connection with element '88,, the rear end portion ofy element 61 is vpositionedagainst the lower face of part M of hanger 34 and is detachably secured'l to the latter by the holdfast means 15. The forward end terminal portion. of yelement E1'is positioned against the lower face of the part 4| of hangerl 33 and is detachably and adjustably secured to the letter by a headed bolt 18 and a nut 19 coacting with the slot 11 and opening 4.9.

The element 68 is in the form of a coiled spring 88 provided at .its ends withv the hooks 8|, 82.

When element 8,8 is employed with or without element 86, the hook 8| is detachably connected to hanger 33 by passing such hook through open-k ing 49, and thehook 82 is detachably connected to hanger 34 by passing it through openingvll. Element 88 may have link portions for shortening or lengthening.

Each axle will be of like form and will have mounted thereon a tubular spacer 84 arranged between the axle supports 48 of .a hanger.y The ,axle will extend in opposite directions outwardly with respect to the supports 4B and its extended portions are peripherally threaded. A pair of spaced oppositely disposed aligned flanged collars 85, 88 will be mounted on each extended portion of an axle. Each wheel will consist of a pair of spaced parallel annularside members 85,81 merging into a pair of oppositely disposed inwardly extending hub sections 88, 89 respectively seated on vbearingballs 98 mounted on the collars 85, 86.

The hubsections oppose in spaced relation the flanges of said collars. The side members 86, 81

are connected together by spaced bolts 9| carrying securing nuts 92. Spaces 93 are mounted on the bolts 9| and arranged ,inwardly'of the outer edges of the side. Each wheel includes a tire formed of any suitable material such as wood or rubber.`

The tire is `indicated at 94 and consists of an annular body 95l rabbeted on each of its sides to form a reduced portion 96 and annular shoulders 91. The reduced portion 96 extends inwardly between the sides and the shoulders 91 bear l The tire is againstthe outer edges of the sides. disposed in extended relation with respect to the sides of the wheel. A wheel structure is confined on an axle by a clamping unit 98 coacting with collar 86, a support 48 and a threaded extended portion of an axle. y

The hub sections 88 and 89 above mentioned form a combined tire flange and ball race.
