of'whichis greater than its width seas-s: As -shown inthe patent before as tioned', the walls of the recess are inclined ttoward each'f-pther to con tit .31 w dg -i ,35 shaped abutment on-which is adapted to be of a bolt,.'saidcoupling-member provided ranged to engage the inclined walls of the recess, whereby said coupling-member; 1S wed 'ed between said walls when support ng an dbject and at the same time, the nut on the bolt issuitably seated-in the recess- 1n the coupling member. A further object of the invention is'to form in the side walls of the device one or more notches communicating with the recess and into which the bolt or suspension-device carried by the coupling-member may' be swung laterally to permit the insertion and removal of the coupling-member without detaching the bolt therefrom. p

Extending transversely from the; lateral faces of-the body-portionl are a pair of op-' positely disposed'lugs 7 10n=0ppos1te sides of which are: smaller lugs 8, soqas -to 0 betweenthelu-gsgz' and 8inotch's.9:for a purpose tobe later described; Communicating with the recess 4: and usually provided ,within thebo'dyflgaortion ofthe lugs 7 are notches 10 outwardlysfiarin'g from the recess 4. The upperrface or wall 2 ofthe device is provided with an upwardly-extending inverted bell-shaped integralmember 11 preferablycontaining a recess 12 for a purpose to be later described; A 1

Mounted on the inclined faces 6 of the re- 'cess i and which constitute a wedge-shaped abutment therefor'is a coupling-member 13 I having inclined side faces shaped to engage the inclined faces 6 of the recess and with] the ends thereof approximately verticallyformed. The coupling-member 13 is rovlded with a central aperture Li and ith a recess 15 surrounding said opening: and pref-.

In doing this, the bolt 20 is ture so as to'firmly anchor the device against:

This is usually accomplished by oor f the form used for making the'ce'mem titio wall and: temporarily holding it in evices passed through the notches '9 existing betweenthe lugs 7 and 8, after which the soft las'tic -cemen'titious material is placed in the orm and completely incloses the device so as to support the latter solid. Afterward the floor of the 'form is removed leaving the device embedded in the wall approximately as shown Figs. 3- an'd 4.-.- t

. The parts are assembled as follows: A nut 'of suitable size is lac'ed on one oi the seats the threaded end of the bolt .passed' upsuflicient diameter to clear the threads on the bolt and the coupling-member" 13 is inserted swung laterally into one of the notches 10 which are provided for this purpose, that is to say,'are so formed and ositioned as td permitJthe-tilting of the b0 t suflieiently t6.

mem'ber13 in therecess4. As these notches 10 are provided at one pointonly in the' side} the position of the coupling-memberl3 to a point opposite tefl one of the notches 1Q in Order, to permit-the withdrawal of the'sam e'll walls '0':- the member 1 it is necessary to shift:

When the coupling-member has been' positioned with its inclined side faces 'resting against the inclined side faces 6. of the recess and-which constitute a wedge shaped abutment for this purpose, the bolt may then. be

revolved to force its threaded upper endv against'the roofer upper wall of; the recess fl: and by the pressure exerted-by the engage ment between the nut 18and the threads on the bolt, the coupling-member 13 is securely clamed against-longitudinal shifting, and

it wi be apparent that if it is desired to re-' move the member, the bolt '20 must be unscrewed sufiiciently to permit it to be tilted in themanner shown in Fig. 4: which permits its ready withdrawal through the opening formed in the outletof the reoess.

An anchoringdevice for the purpose set forth comprising a body-portion having a recess formed in the lower portion thereof and provided with side walls inclined in ward toward the lower face thereof to constitute a wedge-shaped abutment, each of said side walls 'bein provided with centrally-disposedlatera extensions arranged my hand in presence of two subscribing wit.-
