To all 'wh-'om t mag/concerne DoN and ROBERT I. Eus'ris,both citizens of the United `States, residing -atthe city'- of Los',Angeles, county of Los Angeles, and

State of California, have .invented new .and`

useful Improvements in vShorifng 'l `ools, of which the following is a specilication.

Our' invention relates t'o that class of shoring tools used for truing up floors and other like structures and also for bracing surfaces that are unequal] or irregular distances apart; and the object thereof'is to provide a cheap, simple and eilicient tool forthat purpose. vWe accomplish this -object by illustrated in the accompanying drawings, in which: 1

Figure 1 is a longitudinal view partly in section,of our invention. -Fig. 2 is a side view partly in section. Fig. 3 is a sectional view von the line 1-1 of Fig. 1. Fig. 4 is a cross section of a mo'diiedform.

'In the drawings 5` is the base member which is preferably tubular lin shape. The upper end of said'base member is preferably provided with ahead or cap 6 which has -an inwardly projecting flange 7, extendfing to and surrounding an upper member 8,.

Flange 7 has a portion 9 of its inner diameter flattened as shown in Fig. 3 which registers with a .flat portion 10.0f the periphery of the member 8 to prevent rotationof said upper. member.v

with a number fof transverse lopenings 11 throughout vits length for the reception of a pin 12. by which it can be heldin its adjusted position. -A lower threaded sleeve 13` having at its lower end an enlarged base 14 prvided with lugs 14:.L for the reception of a wrench. `This sleeve is adapted to Yfit upon cap 6 and to be revolved thereon. Surrounding sleeve 13 and in threaded engagement therewith is an upper sleeve-15 having at its upper end an internally ex- 'i5 adjusted so that the upper sleeve is at itsl tending liange 16 whichsurrounds and bears against upper 'member- 8. A transverse opening 17. in base member 5 just below .head l6 is provided for adjusting purposes.

In-4 the operation of our device it 'is first lowest position on the'lower sleeve. The

'base is then placedupon its support. The

Upper member 8' isof a diameter to fit the interior of base member 'andfreely slide thereinand Vis provided upper member is`{ slid vtofcontact withi'the i' partl to lb eadjusted or supportedandvthe pinis run through ther aperture nearest the .top ofthe-sleeve.. This 'aperture will be at 1:-

A'or above' the'top ofthe upper sleeve. ,1f theV` pin isabove the end of the upper sleeve the lower sleeve is rotated until it forces the. up# --per sleeve into Contact with the pin passing through the upper member. A further rota'- tion of the lower sleeve will cause the upper memberh to movethe part to beadjusted as far -as is necessary tobringone of the aper-` tures in the upper member into register with the aperture passing throughl the base member. .A A pin isthen run through the opening in both members, when the upper sleeve can be run down allowing the pin in the upperv `ber, this operation being repeated until the" required amount of adjustment is obtained.

In Fig. 4 the aperture through the-cap of the lower'member and the upper member are yoval to member.

The'base of the lower sleeve may have any .base member sufficiently heavy the capon the top thereOfmay be omitted.
