-1'o allwhomitmag concern:

. Be it known that we; JAMEB A. EREMON, and James H. CARKEET, of Montgomery, in the countyof Montgomery and State of Alabama, have invented certain new and useful Improvements in Roller- Skates; and wcdo hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the aecompanyingdrawingsand to the letters of reference marked thereon-which form a part of this specification.

'. The nature of our invention consists in the con-- strnction and arrangement of the devices whereby the .,rollers or runuersare attached to the foot-support of a skate,. in such a manner thatthey may be swung to run the skate in a curved'line, to the right or left.

' In order to enable others skilled in the art-to which ourinventlon appertains to'make' and use the same,

we will now proceed to describeits construction and operation, referring to; the annexed drawings, in winch-- Figure. 1- is a side elevationof'onr improved skate,

with one hind wheel removed.

' Figures-land 3 are detached views of the truck,

in which'the rollers or runners are held.

Ai epresents-the foot boardpr foot support; B the nietallioheel-frame; O, t-heheel strap, and D the 'foot-stra p"of a roller-skate,-all constructed and arranged in any of the known and usual ways. 1

I011 the under side 'of the foot-board A, at-the. point where it is desired to have the rear rollers, is secured a casting, E, by-means of a screw, a, passingupwar into the foot-board, and aheaded bolt orscrew, b, passing downward through the foot-board into theting, the head of said belt or screw being connter-' sunk-in the foot-board,so"as to present an even sur The casting E has a comparatively largeflat surface-on top where the-foot-board tests, and .its center 'then extending downward, is curved forward, and

then toward the rear, where itis flattened and pro- The shape. of the casting E is fully shown in fig. 2,

. from which it will be observed that the slotted portionbf the casting stands at an angle of about fortyfive degrees. I z

Att-he rear end of the casting, immediately above and in rear of the slotfe, is a. flange, it, running across the end and projecting on-beth .sides, for a purpose that will-"be presently described,

, flherollersGfi are placed in aframe construct ed in the 'following manner! H A center bar,'H-, of the same width as the intendeddistance 'between the two rollers, is, at its upper end,fprovided with a crossbar, I, extending on both sides, and its ends bentso as to run parallel The rollers G G are then placed one on each side of the center-bar H, and the a clczJ passed through the ended the bar or armI, and through gt-he centers of the rollers; it also passes through. cars 5 i, formed upon the upper side at the lower end of the central bar H.

At the lower end of the central bar H is a pin or pir'ot, f, and at the upper end is'another pivot g.

The lower pivot f, is insertedin the slot 0 in the cast ingE, while the upper pivot, g, is inserted in a socket or bearing, K, secured at the heel onthe under side of the foot-hoard A.

Between the center-harH of the roller-flame, and I the casting E, is inserted a rubber-block, L, which is compressed between said bar and casting when .put together, and acts as a spring to. hold the rollerli'arne'with-tho rollers in proper position.

By the motion of the skatcrs foot, the roller-frame H l' is -turnedupon its 'pivots toward either side, so-that the skate may be runin a curved line-to the right or left.

The roller-frame does, in fact, =only turn on one of its pivots, namely, the upper pivot g, which is inserted'in the socket K, while at its lower end the projecting end of the flange d bears against thcback of the center-bar H, moving the lower pivot f for-n ward in the slot 6.

By the motion of the rolleiii'anie to either -side,

that portion of the rubber I ,,onthe side toward which the frame turns, is still further compressed, while on the other side it expands; hence, as soon as the force which caused the turning of the roller-flame is i'ernoved or ceases to operate, the rubber will-cause the roller-flame to resume its proper position under the skate; I

The'trncle under the footer toe of the skate is constructed in precisely the same manner, only turned in the oppositedircction, as shown in fig. 1. The advantages of our improrement may be described as tollowsr v g The projecting flange or cross-bar d at right angles to the. slot 0 corresponds withja'nother horizontal projection upon the wheel-carriage, above the pivot f,"

the object of whichis to keepthe wheel-carriage in a,

horizontal position upon the platform or foot-board'ol' skate, or to right thew-heels on platform by He'lastic .action of the rubber-pad. v The object of, the slot ale to allow'the separation of the two straight-bearings or horizo'ntalbars, and at the same time to allowpressure to be made upon the rnbber pad, the ends of the,

-slot to restrict the motion of spindle of t!1e' \vl1eel-ca1'- I 'riage vertically. v

The coustructionof the center-piece admits of.

greater oscillation of wheel-carriage, and admits also-H the use of larger rollers than usual, the advantages of which are rapidity of motion with much-greater ease of action to the skater, diminishing the tendency to heat, at the same time not removing the foot of the skater further from the floor. The angle of oscillation being so much greater, admits much more ease to the skater in turning curved lines;

Having thus'fully described oilr invention, I

What we claim as new, and desire to secure by Let-. ters Patent, is-

1. The hanger E provided with slot 0 and cross-bar d, in combination with center-bar H, pivot f; and cushion L, all constructed and arranged to operate substantially as and for the purpose set-forth.

2. The wheel-cerriage H I having pivots f g, in

' purpose set forth.

In testimony that we claim tlieforegoing as our "own, we afiix our signatures in presence of two witnesses.
