d This invention relates to an improved anchorage for securing a threaded element Such as a bolt orv similar fastening device in'an aperture ina wall or other building struc-` ture of stone, brick, cementitious or like material. The invention further relates to methods of forming such an anchorage.

One of the objects of my invention is to provide an anchorage having relatively hard and relatively soft metal pieces so combined as to form a firm and secure anchorage.

Another. object of the invention is to provide a newmethod lfor forming an anchorkage comprising relatively hard non-elastic metal and relatively soft ductile metal.

. Further objects of the invention will ap# pear as the description proceeds.

Y Figs. 13 and 14 showin sectional elevation andy transverse section another form ofthe invention and Fig..15 is a sectional elevation of still another forinof the invention. l

Like characters of reference designate corresponding parts in all the figures of the drawing.

Referring first to the form ofthe invention illustrated ,in Figs. 1 yto 3 inclusive',"I have showna'portion of a wall 20`of a building structure, this wall having an aper-y ture ork hole 21 bored therein'v to receive a bolt 22 or other'fastening devicel Assn-m4` ing that the wall' 20 is formed of stone, brickor cementitious material it will'v be evident that some form of anchorage must be provided between the bolt 22 and-thel surl face of the hole 21.

The form of anchorage shown in Figs. 1`4 comprises a tubular member shownin the form of` a spiral 23, the diameter offthis member being substantially that of the hole 21. This tubular spiral member` is formed of non-elastic, relatively hard, expansible, material, and there is-- positioned withinL this tubular member another tubular member or sleeve 24 of relatively soft ductile material. The bolt or retaining member 22 isposi-k tioned within the sleeve 24 and in lorder to forni an'anchorage the soft metal sleeve 24 is compressed within the opening 21 in any suitable manner yas-by tamping.

y ln Fig. 3l have shown an anchorage after the sleeve 24 has been compressed and it will be noted that the compression of the sleeve Vforces the soft ductile metal into engagement ywith the threads of the bolt 22 and also forces the spiral 23 `outwardly into Vfirm engagement with the wall of the openingA 21. l It will` also be noted thatfthe soft metal of the ksleeve 24is forced through the opening in the spiral and also engages the wall of the vopening 21. There is vthus formed a firm' and secure anchorage, the engagement ofthe spiral 23with vthe wallof the opening effectively preventing the withdrawalfof the anchora'geand this spiral of hard metal also strengthening they anchor'.- age structure.y

In Figs. 5`and 6 I have illustrated another ,form of the invention in whichy the spiral tubular member 23 is positioned between the bolt-*22 ofthe soft metal sleeve 24. It will be evident that compression of the sleeve 24 shown in Fig. 5 will force this sleeve, into `firm.engvgagement with the surface orwall of the opening 21 and furthermore the `ductile material will be forced yinto vengagementwith kthe spiral 23 and with the threads von `the v,

bolt 22.' f

InFigs. v7, 8, 9 and l0 l have illustrated ianother method offorming the anchorage andin this embodiment as' in the form of the inventionshown in Figs. 1 4, the sairal 23 is positioned between the soft metal sleeve 24 and the surface or wall of the opening 21. bolt 22 wit-hin the sleeve 24 before compressing thesleeve, in this form of the .invention I use a mandrel 25, the sleeve 24e being compressed by vmeans of a tubular member or sleeve 26 which is positioned on and is adapted to slide on the mandrel thereby compressing or Aswa'ging the 'soft metal sleeve `211 into engagement with the mandrel 25l and also forcing the metal of the sleeve 24 outwardly through the openings i'n the spiral 23 and pressingthe spiral intoV firm engagement with the wall of the opening 2l'.

InV Figs. 9 and 10 the anchorage formed by this method is shown and from these fig-V ures it will be seen that after the Vmandrel has been withdrawn the inner surface o1 the sleeve 24 is formed with a plurality of inwardly extending longitudinal ribs 2T into which threads may be cut by the threads on lthe bolt 22.

In Figs. 11 and 12 lstill' another form of the invention is shown and in this form the Spiral 23 of relatively hard metal is positioned in the body of the sleeve 2a of relatively soft metal. In order to form the anchorage, the 'sleeve 24: with the spiral 23 formed therein `is positioned within the yopening in the wall and the sleeve is compressed by one of the methods above described. `The compression of the'` sleeve shown in Figs. 11 and 12 will force the "sleeve into engagement with the wall ofthe opening' 21and also with the bolt 22, if the Ymethod shown in Ijigs. 141 is used, or with the mandrel 25', if the` method shown in lfigs 7 to 10is used. Sucha compression of the sleeve would also obviously more or less distort and compress the spiral 23.

In Figs. 13 and 14 still another embodinient of the invention is illustrated. In this form aplurality of longitudinally extending hard "metal strips 28 is positioned within the opening21 in the wall, these strips as shown inA Fig. 13 `bi-iing shorter than the depth of the opening in the wall. The sleeve 24 of relatively soft material is positioned within the opening inthe wall and also withinthel strips 28. l/Vhen thesleeve 2% is Compressed by one ofthe methods already described "the relatively soft ductile material will be forced outwardly between thest'rips j28 into engagement with the wall of the opening 21 `and this material will also force `the strips 21 into firm engagement `with the inner surface of the opening. The strips therefore assist `in strengthening the anchorage and in holding it in firm engagement within the opening 21.

Fig. 15 shows still another form of the invention in which thetubular member is formed of coarse netting or wire mesh 30.

Instead, however, `of positioning the The soft metal lining 211 is pressed through the mesh and engages the bore of the opening and also presses the wire into engage ment with the wall `of the bore.

From the above description it will be seen that a firm and secure anchorage may be formed of relatively hard and relatively soft metal pieces, tl'iese pieces being tamped or pressed into engagement with each other and with 'the wall or supporting structure.

Although certain speciiie embodiments 'of the invention have been illustrated and de scribed it will be evident that the invent-ion is capable of further modifications and that further changes ,inthe construction and in the arrangement of the cooperating parts may be made without departing from the spirit or scope of the invention as set forth in the following claims.

What I claim is:

holding the inner end of the sleeve againstV `inward longitudinal movement and applying inward longitudinal pressure to the outer end of the sleeve whereby the sleeve and tubular member are brought into tight engageinent with the surface of the wall of the bore. i

2. The method of anchoring a threaded` element which consists of forminga recess in the body to which theV element is to be anchored, inserting in said recess a deformable sleeve of relative-ly soft, ductile material, a
