claims; but, for a full understanding of our invention andof its objects and advantages,`` reference maybe had to the following de-V tailed description taken'hin Vconnection with the accompanying drawing, wherein: y,
Figure l is a top plan view of a pair of jacks associated with a beam that serves as a base 'for both and as a spacing means'ptherefor; and Fig. 2 is a section taken on approxA The two Vj acks illustrated description of onewill suffice for both. Y The body 1 of the jack is made of a piece of thinwalled steel pipe. Set intoy one end of the pipe is a head 2 thatis preferably pro-vided Vwithra lug 3 that enters a notch l out into the end of the pipe, to prevent the head from f turning. A jack screw 5 passes through the head and is provided on'its outer end with suitable means by which it may beturned In the arrangementfshown,the screwhas on the outer end a ball 6 through which are boredholes V7 and 8 to receive a rod or lever;
A foot 9 is swiveled tothe ball and is adapted to engage with one of the members between which `the jack is placed.- The jack screw is much shorter than the body'ofthe jack, permitting the base end of the bodyto be filled with concrete v10.
In using the jacks in groups, a plurality 'Y l of them are set into the channel of a chanusing the jack in `the @0a-v` are alike` and the nel beam 11 that willserve as acomrnon base or as a waler extending transversely .across the lagging in a trench, where the jackshare employed toV sustain the sides oft-he trench. y It is preferred that thekjaoksbe interlockedw with the beam tol permitthem to. be easily set upjin proper spaced relation to'eachother v and be` held there. In;V the arrangement shown, the beanifhas discs riveted or otherwise securedl to/the inner side 0f the :web gvthese discs being of the samefdiameter as the internal diameter' of the body member The concrete within the'jack of the jack;
terminates a short kdistance from the vend of Y vthe latter so as to leave roomfor theentry of one of thediscs. i
` Vhile we Vhave illustrated `and described f' withp'articularity only single preferred form of our invention, we do not desire to be limited to the exact structural details thus illustrated and described; but intend yto cover all forms and arrangements -Which come within the definitions of ourfinvention constituting thelappended claims.
