Wedge member W is engaged between the rail M and. the free end of the hook of the bei* 5- lesse the wedges member 7, the outer longitudinal merg-in c ci the member 'i' being' disposed on en incline snbstentielly complemented to the in-` clinstion of the end b of the hook member 7. The wedge member W is applied into working position through the outer side of the applied bei' 5 and es it is forced inwardly the wedge assures ellective clamping en- Psagement with the rails M, and G.

The outer or larger end of the wedge member ll is provided with a. laterally disposed and outstanding 'flange or extension 8 through which is freely disposed a bolt 9, seid bolt being' also freely insertible through the hook member 7. After the wedge bes been pro erly positioned e holding nut 10 is 'three ed upon the bolt 9l for coactiou with-the inner fece ot in desired applied position.A lin practice, I 5nd it ci' importance to interpose between the applied nut' 10 and the bool; member T e. spring, Weeber 11 which provides means to compensate for expansion or contraction incideiit to temperature changes and also tol 10 sgemst backing ofi.-

The cooction between the inclined side fece 12 ot the block B and the outturned ortion 1 of the reil G- holds the applied b ook B egeinstmovcment inwardly of the rail G.

As the rail G wears and it is found necessary to move or adjust said rail G with respect to the Ymein rail M to maintain the standard spacing, it is only necessary to re- W end to suiiiciently withdrew the ller bloclr B and bars 5 to eiiiect the requisite movement of the guard rail G toward the ruil M. liben the desired adjustment lies been accomplished the bers 5 erethen eiectively held to the rails M end.

I also ind it'o advantage to have the outer fece of each of tilt-:wedge members W et its lower portion provided with en outstendinrr flange 15 to extend between the hook members 7 and the adjacent end portion of the ber 5 to provide effective means to en appliedwed e men'ilcer.,v
