. This invention relates tov anchoring devices V the adjacent edgeof the wall. 1

, for bucks for door frames or window frames interposed inwalls constructed of a plurality of building units, such as fire proof tiles.

In constructing fire proofv walls from tiles or other building units, it is desirable to have some effic ent means interposed betwcenl layers of buildingzunits andcemented'therebetween forws'ecurely anchoring the timber or portio nfofa door buck to maintain-the same in properupright position. This invention has for its object :to provide an exceedingly simple but highly eid cientj-buck anchor which may be easily ,in-

stalled. When the walls, are being erected, having means for straddling' a leg of a buck and securing the same-in proper'position to It is a more specific object of the ;.tio'n.to provide sucha buck anchor comprising a relatively'fflat elongated plate adapted to beset in the plaster orlmortar between P two-.layers of building units havingmeans to prevent lateral longitudinalv displacement thereof; and having means projecting beyond an edge ofthe wall and adapted to engage the edges of a buck and be secured thereto.

' .'-It is a further objectto provide a buck anchor provided, atone end with a .pair of fiat projecting tongues adapted to be seated in oppositely aligned grooves in the edges of a 2x4: or other timber used for the ,door buck,' saidtongues being of sufi'icient length to extend beyond .the outer surface of the buck, whereby the extremities of said tongues may be bent inwardly and nailed or otherwise secured ,to said outer surface."

It is a still further objectof theinvention 'to provide, such a buck anchor especiallyadapted to engage j and straddle a 2x43but capable of being combined-with; another similar anchor-to engage the leg of a buck constructed from .larger fit 'mbers, such as 2x6s and 2x8?s.--

The legs of a door buck are-indicated by the numeral 5having cut" at intervals'ialong the side edges thereof, the oppositely disposed aligned horizontal grooves 5 The grooves may; be formed inthe12x4s or timbers constituting the door buck beforethe same are applied to the walls or, if desired-,'
