v Claims. c 1.zs0--11.2'

The present invention relates to an attachment for The attaching of the toe'stop' to the wheel .truck. results in a particular'advantage over the stops now in general use, which are attached to the underside of the sole plate;

ofa' skate, in that the stop of the present invention turns or otherwise moves with the wheel truck. It follows, therefore, that when the stop comes in contact'with the floor, it engages the floor squarely whereas, were it. attached to the soleplate, it would strike the floor at an angle likely causing the. skater to be thrown 01f balance or suffer a fall.

.Heretofore another disadvantage of many toe stops.

has been the fact that they wear so rapidly. It is therefore another object of 'the present invention to provide astop member, which can be attached to a toe-plate member in'a plurality of.positions to thereby present a num: ber of successive surface positions for contact with the floor as the originally presented surfaces wear-down.

Another object of the present invention is to provide. a toe-stop attachment comprising an elongated; plate memberhaving a transverse portion adjacent. one endv with an opening therein for receivinga king-pin for attachment to a roller skate,. a portion forward .ofj'this opening having a substantially 'Uvshaped bend for abut ting relationship with the wheel axle housing of the front wheel truck, an inclined portion extending from the forward arm of .the U-shaped portion extending substantially the length of the. inclined brace member of the front wheel; truck for abutting relationship there- 1 with, and atransverse portion forward of this inclined portion having a stop member selectively attached to an underside thereof. v v

Referring now w th drawings,

to the'skate itself, it can be seen thatxthe skate herein illustrated is a conventional one designated generally by I the reference numeral-1. The skate comprisesasol'e" plate 2 with hangers 3, 3 attached vtothe under side ofplate 2 adjacent the forward and rearward ends there of.- .iThese hangers'maywbe attached to the'platein any, conventional manner, such as with rivets. The hangers: 3,'-3'*havetwo tubularextensions 4, 4' and 5,, 5 for purposes hereinafter described, the extensions 5, 5fJbe-i -ing internally threaded.

The skate has front and rearwheel trucks-designated generally: 6,v 6. These truck members 'have' axle lions-- ings .7, 7 which carry wheel axles 8, 8'. :Pairsof-whe'els 39 and 40 are carried byithe front and rear: axles respectively. The wheel trucks are also providedwith two arms or braces 9, 9' and 10, lfl angularly displaced with respect to eachlaother- The. arms 9, 9.: are supported in socketed rubber blocks 41 positioned within thecupped recesses of hanger extensions 4, :4" while the arms 10,

i or washer 15, both containing openings through which side with-,respect to the truck member.

the king-pin 12 extends. --A,brace '16 extends between the front and rear king-pins'll, 12 -and hasani opening adjacent each end to receive the king-pins. -A lock nut; 17 is carried by the threaded portion 13. of the king-pin betweenbrace member-16 and. the. internally threaded extension 5 of the hanger. The king-pin 12 has an en-' largedhead 18 and carries between thisenlargedhead and the.dish.-,shaped wheel truck extension 10 :anotherdish-shapedmember or washer 19-anda secondresilient member 20,--both having openings,.through.which the: king-pin extends. It can beseen therefore that because ofthese resilientmembers 14 and 20,.and the-clearance between the bolt 12 and the .walls of the opening in the part ,10, the plate member can be :rocked from side to The: freedom of rocking or turning movement can be adjusted by, loosening the lock nut 17 and drawing the. enlargedh'eadi of king-pin 12.into tighterv or looser engagement with the resilient members. 7 The improved toe-stop attachmentpf the present invention comprises an elongated relatively-rigid member 21- made .of sheet metal stamping of rathenheavy "gauge or .ofzlike construction, having a portion.;22 adjacent its rearward end lying in a generally-horizontal plane,;dis.-. posed snugly adjacent the dished'part 10 of .the wheel mounting, and having an openingtherein through which, the vking-pin 12 extends. #:The member.21 has a substantially U-shaped bend 23' forward of the substantially horizontal portion 22 to embrace the wheel axle housing 7 of.the front wheel truck. Theforward leg of the U-shaped portion is extended upwardly. and forwardly in the form of an extension 24. The extension 24 h as a reinforcing bend. or convolution forming va-rib -25 running the length thereof, the ribbed extension 2 4 being disposed in abutting relation with the inclined brace and more particularly in a portion 2.5 also lying in an approximately horizontal plane. The forward portion 25 of the plate contains pairs of apertures 26 and 27 for purposes hereinafter described.

The brake or toe block itself comprises a block 28 of hard rubber or' a similar material'and is made in the form of a cylindrical sector, which in the illustrated.

embodiment is a quadrant. The radial faces 29 and 30 of this sector have av portion cutaway therefrom on. both sides of the junction of said faces and an angular plate member 31 is imbedded in the recess thus formed. The plate member 31 is. secured in place as by vulcanizing or bonding the rubber. to the plate. As can be seen, the angular plate member 31 has sides 32 and 33 with the included'angle'of these sides being substantially the same as the included angle of faces 29 and 30 of the toe block. Theplate member 31 also contains an inwardly struck central groove 34 extending the length of the plate. This groove acts as a strengthening rib as well as an aid in holding'the plate imbedded in the block. A plurality of apertures 35, 36, 37 and 38 are also provided inthe plate member 31.

It can be readily understood that with the double apertures 26 and 27, the toe block 28 can be adjusted forwardly or rearwardly with respect to the front of the skate by positioning the holding screws 42 in the apertures'26 or the apertures 27. It can also be readily seen that the block can be attached with either of the faces 32 or 33 in abutting relationship with plate 21 by the alternative use of the respective pairs of apertures 37, 38 and 35, 36. Thus with this double adjustment, a skater can get four times the Wear that he would normally get were there but one set of apertures 26 or 27 and were the block 28 itself only attachable in one position.

The toe-stop attachment as illustrated and described above is by way of example only, and any changes which might occur to one skilled in the art are contemplated by the present invention, within the scope of the following claims.
