To all whom it may concern.'

Bef it known that I. Fonns'r FINLAY, a subjectof the King of (lrreat. Britain, residing at No. -10a Cannon street, Petershaln, near Sydney, in the State of' New South llf'ales and Commonwealth of Australia, -mechanical engineerhave invented new and useful Improvements in Roller-Skates, of which the following is a specification.

This invention relates principally to extensible roller skates in which the frame is constructed with a fore or toe frame and an aft or heel frame each adapted to slide in or upon the other and he clamped in position for the .purpose of adjusting the `length of the skate to varying lengths of boots andshoes, etc.. Worn by,the users though parts are applicable to inextensible skates.

According to this 'invention the present improvements consist first in construct-ing the overlapping extensions or shanks of the fore or solepiece and of the aft or heel piece of channel section s0 that a maximum 25 of rigidity is attained and expeditious and leasy adjustmentas to length or size of the skate sole is possible secondly in forming the outer. of the brackets of the front and rear axle bearing supports of a plece cut from `the sole of the Yskate and bent down-y wardly and outwardly thirdly in strengt-hening the toe of the sole and the forward bracket of the front bearing support and atthe same time providing a bearing for the adjusting screw of tlie toe clips" b v a' rib or fin fourthly in strengthening the rear or( outer bracket of the back bearing support by a rib or finand fifthly in formingthe inner stayor brackets of lthe axle bearing supports with flanges or lips to engage the sides of, said bearing supports and so firmly hold same.

In order that a practical application of the present improvements may be readily understood the same will be described with .reference to the drawings accompanying and :forming part of this cation in which- Y* Figure 1 is a perspective view of a skate constructed with the present improvements incorporated. Fig. 2 is a sectional elevation complete specifionV the plane 2- 2 Fig. 1 looking rear# wardly. Fig. 3 a similar view on 4the -plane 3-3 Fig. 1 looking forwardly. -Fig.

4 is a longitudinal central sectional elevafrom the angle of line 8-8 Fig. 4.

The sole piece 9 has its overlapping part or shank 10 of channel section preferably of arched shape with slot. 11 and orifice 12 and the heel piece 13 has-asimilar corresponding shank 14 and this has flanges 16 slot 17 and orifice 18. The stem shank 10 and the shank 14 under or overlap the siot 17 in the latter being positioned .above the orifice 12 in the former and a clamping bolt 19 preferably with its head uppermost passes through both and through orifice 20 in the stay' bracket 21 which is attached to the front axle bearing supports of known construction and has' flanges er lips 22 to y engage the sides of said bearing sup rts.

The slot 11 of the toe piece 9 trave s beneath the orifice 18 of the heel piece 13 and a clamping bolt 23 preferably with its head uppermost passes through both and through orifice 24 in the stay bracket 25 which is attached to the back axle bearing supports of known construction and has flanges or lips 26 to engage the sides of' said bearing, supports. c

The front or outer bracket 27 of the front bearing supports is formed of' a -piece cut and pressed from the sole plate `28 and the toe of said sole plate is supported and strengthened by a. rib or fin 29 riveted to or formed Ion the under side of the sole plate 28 with its rear end 30 abutting and staying said bracket 27 and having a slot 31 forming a bearing for the adjusting screw 32 of the toe clips 33. The rear or outer bracket 34 of the back bearing support is formed of a piece cut and pressed from the heel plate 13 and said bracket is stayed by a rib or fin 35 riveted to or formed on the under side of the said heel plate 13.`

In use the skates may be extended and closed by loosening the bolts 19 and 23 drawing the toe and heel pieces apart or pushing them together and are locked at the desired length by tightening said bolts.

The special construction of the overlapping extensions or Shanks of the toe and heel pieces though preferred ofthe arched channel shape as shown may be of any shape such formation of bracket for the axle bearing manufacture of the skates the ribI orin shank portioii,'said shank portion being proy bracket of the back bearing supports.

as V channel soiuare channel or tapered fiat channel shape in section in which the clamping bolts may pass through both shanks and slide inand upon them sot-hat a maximum rigidity is attained while facilitating and expediting adjustment of the length of skate without removing the clamping bolts the supports of a piece of the sole'plate or heel plate simplifies cheapens and improves the under the toe of the sole plate strengthens same and prevents it being bent and cracked and stays the front bracket of the. front axle bearing supports and the rib or plate under the heel of the sole stays the rear axle What I claim, and desire to secure by Let-- ters Patent ,of the United States, is 1. In extensible roller skates, in combination, a sole plate provided With a channeled vided with a slot and an orifice and a heel j plateprovided with a channeled shank portion., said shank portion being provided with A an orifice and a slot, said channeled shank portions overlapping one another, one of? said channeled portions being slidingly positioned `within the other and the orifice in each shank portion registering with the'slot f in the other shank portion. e f

2. lin roller skates, a foot supportingplate, outer and innerbrackets forming'an axle,I

bearing support, said outer bracket being formed out of the material of the plate and bent downward and outward and a down.-

wai-diy extending rib extending longitudinally with respect to said plate and abutting the bend in said outer bracket- 3. ln roller skates, a foot supporting plat-e and downwardly extending, oppositely disposed outer and inner brackets, an axle bearing support positioned between said brackets, said inner bracket being provided with inwardly extending flanges adapted to engage the sides of said support and hold it against lateral movement. i l

4. In extensible roller skates, in combination, a sole plate provided with a channeled shank portion, said shank portion being provided with a slot and an orifice, and a heel i plate provided with a channeled shank portion, said shank portion being provided with l an orifice and a. slot, said shank `portions overlapping one another, clamping bolts passing through said orifices and slots to E hold the platesv in adjusted position, and laxle iii,
