ROLLER SKATE.

application'filed March 15, 1923. Serial No. 625,239.

- To all whom it may concern:

7 3e it known that I, PERCY O. GinsoN, a citizen of the United States of America, residing at Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Roller Skates, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to roller skates of the four wheel class and has special refer' ence to a'skate having metalllc parts stamped and pressed from sheet metal to form a strong and durable skate structure The object of my invention is to provide a skate which may be adjusted to fit shoes of various sizes and such adjustment is accomplished by an extension member slidably mounted relative to bearing members attached to the sole and heel piece of the skate. The configuration of the bearing and extension members is such as to afford a rigid longitudinal girder lengthwise of the skate insuring a substantial platform for a '25 shoe, besides preventing twisting or lateral displacement of one bearing -member relative to the other. With the skate firmly secured to a shoethere is no lost motion between the parts of the skate which would 36 cause a loss of control when skating, and these advantages are gained by metallic parts that can be easily and quickly assembled to provide a structure free from injury by ordinary use and highlyeificicnt as a rolling foot piece.

The construction enterin into the skatehe sole piece and adjacent the toe of this sole piece are opposed transversely alining shoe sole gripping members or clips 2 slidably held on the lower face of the sole piece by rivets 3 extending through slots 40f the members or clips 2. The confronting depending ends of the clips or members 2 are articulated by a right and'left hand screwthreaded connecting member 5- which may be rotated to adjust the cli or members to and from each other, and it is by, virtue of these clips or members that the sole piece 1 may be attached to shoe soles of various widths.

The reference numeral 6 denotes a heel piece having an upstanding lug? and riveted or otherwise connected to said lug and also to the side edges of the heel piece 6 is a strap member 8 adapted to embrace the rear portion of the shoe and permit of straps or other flexible members being employed for attaching the heel piece to the shoe, whereby the straps may cooperate with the clips or members 2 in retaining the skate on a shoe.

Connectedto the lower faces of the sole and heel pieces 1 and 6 respectively are longitudinally alining channel bearing members 9 and 10, said members being connected to the sole and heel pieces by rivets 11 or other fastening means. The bearing members 9 and 10 are stamped or pressed from sheet metal and said. members have depending parallel flanges 12 and apertured bearing lugs 13. Suitably mounted in the bearing lugs 13 are transverse axles 14 provided with lug spacing sleeves 15 and rollers or wheels 16. As shown the rollers or wheels 16 are on the ends of the axles 14, thus providing a four Wheel skate. The rollers or wheels 16 may be of an anti-frictional type made of metal or any other type of roller or wheel may be used.

The reference numeral 17 denotes a channel shaped extension member slidable in the bearing members 9 and 10,,said extension member having parallel flanges 18 against the inner faces of the bearing flanges 12. The ends of the extension member 17 are provided with longitudinal slots 19, and mounted in each of the bearing members is a bolt 20 provided with a nut 21 and suitable washers 22. The bolts 20 may have the heads thereofin openings 23in the sole and heel pieces 1 and 6 and with the washers 22 engaging the extension member 17, the bolts as I .20 may be tightened and the extension member clamped against the bearing members 9 and 10 to hold the sole and heel ieces in anadjusted position relative to eac other.

It will be noted that the slots 19 will provide clearance for some of the heads of the rivets 11 and that the channel extension no member will cooperate with the channel bearings in forming a rigid longitudinal girder lengthwise of the skate, it being practically impossible to break down such girder by the Weight of a person on a pair of skates.

One embodiment of my invention has been illustrated but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

What I claim is:

l. A roller skate comprising sole and heel pieces having means for attachment to a shoe, bearing members rigidly connected to said sole and heel pieces, roller equipped axles carried by said bearing members, an extension member slidable between said bearing members, and means fixed relative to said sole and heel pieces adapted for fixing said extension member relative to said sole and heel pieces.

2. A roller skate as called for in claim 1, wherein said bearing and extension members have a cross sectional shape lending a rigid girder likestructure lengthwise of the skate and in Width approximating the distance between the rollers of each axle.

3. A. roller skate comprising sole and heel pieces, adapted for attachment to a shoe, channel bearing members connected to said sole and heel pieces and provided with sets of: bearing lugs, a channel extension member corresponding in cross section to said channel bearing members and slidable in said channel bearing members and between the bearing lugs thereof, said channel extension member being longitudinally slotted, nut equipped bolts fixed relative to said sole and heel pieces and extend ing through the slots of said channel exten sion member to fix said extension member relative to said bearing members, and rollers supported from the bearing lugs of said bearing members.

In testimonywhereof I afiix my signature in presence of a Witness.

I PERCY O. GIBSON.
