ROLLER-SKATE.

Specification of Letters Patent.

Patented Nov.1'2, 1912.

Application filed August 14, 1911. Serial No. 644,019.

Toall whom it may concern:

Be it known that I, THOMAS E. KING, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented a new and useful Roller-Skate, of which the following is a specification.

This invention relates to roller skates and has for its object to provide an improved,; substantial and cheap device of this chari in the socket 11.. The horizontal arms 24 of acter.

means for changing the alinement of the rollers according to the shifting of the.

With the above ends in view this inven-;

tion is embodied in certaindetails of construction which are hereinafter "described and pointed out in the appended claims.

The invention is illustrated in the accompanying drawings, in WhlCh. similar reference characters indicate similar parts, and

ably stamped and pressed from sheet metal.

v at each end of the skate, each being of L-,

To strengthenthis foot plate has been provided a casting, preferably of wrought iron, comprising an elongated block 7- and an upper flange 6, which flange is riveted to the bottom of the foot plate 5, the casting extending from the heel' portion of the foot plate to the toe portion'thereof. The ends of the block 7 are reduced'indepth as indicated at 10 and have the lower faces thereof declined outwardly toward the end of the skate. In each end 10 of the block is arranged a vertical hole or socket 11.

A vertically arranged stud bolt 21 having the lower head 20 is screwed into each end of the deeper portion of they block 7 and a jam nut 19 on each of the said bolts serves to hold same: in position by binding against the said block 7. A carrier 14 is arranged A further object is to provide improvedshape comprising a vertical arm 13 and a hor1zonta1'arm 24. A pint-1e 12 projects from each of the vertical arms 13 .an enters .the respective sockets 11 in the reduced ends 10 of the block 7 to form a swivel connection between the carriers and the said block. The axis of each of the intles 12 and the corresponding. socket 11 intersects the axis of the corresponding bolt 21 at a point below the floor, and the pintles 12 are slidable axially the carriers have an integral cup 16 at the outerends thereof and a sleeve 23 integral therewith intermediate the ends thereof.

The cupped ends of the arms 24 are mounted loosely on the respective bolts 21 and normally rest onthe heads 20 of the said bolts.

ends of the arms 24 of the carriers throw a greater portion of the weight of the skater,

on the cushion 17, which being resilient obviates the jarring caused by the movement of the skate over the surface of the floor.

Upon the weight of the skater shifting to the carriers will swing about the axes of the pintles 12, which will cause the cup-shaped portions 16 which loosely engage the bolts 21 to move at a greater rate of motion than the lower ends of the bolts, or causing the cup-shaped portions 16 .to move laterally and upw'ardlyrelative to the bolts as the bolts are swung. It will therefore be noted that when the foot plate is sloped to a proper angle, that the bolts 21 will strike the cup-shaped portions 16 for the purpose ed loosely on the bolts 21 and embedded in v of limiting the tilting movement of the foot plate. The lateral motion of the cup-shaped portions 16 relative to the bolts also causes the cushions 17 to be bowed or twisted in order to impede the tilting movement of the foot plate and in order to retain the wheels in alinement unless the proper pressure is applied to the foot plate to tilt same. It 10.

is for this reason that the cup-sha%ed' portions 16 are mounted loosely on the olts 21, and that the tubular cushions 17 are mountthe respective cup-shaped portions 16 and the cups 18. As shown in Fig. 3, the diam- Y eter of the bolt 21 is smaller than the opening in the cup-shaped portion 16 and the I passage through the cushions in order to permit the operation of the devices above described.

.Each end of the block 7 and each of the carriers 14 and corresponding parts are of like design and proportions whereby the parts at the two ends of the skate are interchangeable and being similar dispenses with the necessity of having two carriers of different design and construction. a The block 7 extending from the toe portion of the skate to the heel portion thereof strengthens that portion of the foot plate intermediate the heel and toe which has been found to be the weakest point thereof and which has .otal and slidable engagement with the foot plate on an axis which intersects the axis of the said member below the floor, wheels carried by the carrier, and a cushion on the said member between the foot plate and the carrier, whereby when the foot plateis tilted sidewise the carrier moves laterally at its point of engagement with the said member at a greater rate of motion than the said member at that point in order to impede and limit the tilting movement of the foot plate.

2. In a roller skate, a foot plate, a member dependingtherefrom and having a lower head, an L-shaped carrier having its horizontal 'armloosely engagin the said member and having its vertica arm pivotally and slidably engaged" to the foot plate on an axis which intersects the axis of the said member below the floor, wheels'carried b the carrier, and a tubular cushion dispose between the foot plate and'the horizontal arm of the carrier, so that when. the foot plate is tilted sidewisethe horizontal arm of the carrier moves laterally at its point of engagement with the said member ata greater rate of motion than the said member at that point in orderto ede and limit the tilting movement of the cot plate.

. v v 3. In a roller skate, a foot'plate, a member secured on the bottom of the foot plate and having a socket therein, a bolt screw-threaded into the said member and having a lower head, an inverted cup on the upper end of the bolt, an L-shaped carrier, the vertical arm on the carrier having a pintleengaging slidably in the said socket, the. axis of the socket and in tle intersecting the axis of the bolt at a point below the floor, and the horizontal arm of the carrier having a cupshaped end loosely engaging the bolt, a tubular cushion having the ends thereof embedded in the said cup and cup-shaped end of the horizontal arm, and wheels carried by, the said horizontal arm, so that when the foot plate is tilted sidewise the said cupshaped end moves laterally at a reater rate of motion than the lower end 0 the bolt in order to impede and limit the tilting movement of the foot plate.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
