JOSEPH KENNEDY, 0F NEW YORK. N. lY.
BOLT-ANCHOR.
To all -w/ wm it may. concern:
Be itl known that I, JOSEPH KENNEN. a citizen of the United Statesof America. and a 'resident of New York, county of )few Xork,1aiid-State of New York, have invented certain new and useful Improvements in Bolt-Anchors,l of which the follmving a specification, reference being had to the accompanying.' drawings, forming a part thereof.
AMy invention relates to bolt anchors of the type employed in lholes in walls of brick, Vstone and the like, for securing boltstheretol` and my invention consists in composing the expansible shell ofva bolt anchor with an interiorportion of relatively soft metal andan exterior portion of relatively hard metal.v
In oneform cf my invention, I provide iii addition thereto, a portion exterior the hard metal' portion, of relatively' soft metal whereby the hard metal part .inclosed without' and within by soft metal portions.
The foregoing is advantageous for many reasons. First, it considerablyY strengthens a type of bolt anchor in which threads are formed in a relatively soft metal shell b v the forcing of the bolt therein which is to be held in place. Second, therelatively soft metal will act,'in some forms, as a'pioteetive coating for 'the relatively hard metal part, whereby a hard metal type of shell in which the material is highly corrodible may be'protected by a non-corrodible covering. It will be readily understood that *in v. invention is applicable to many types of b olt both as a strengthening and re-iiimeans. and as protecting means. and
understood, I will now proceed to ough' describe' several structures embodying the` same` having refe-rence to the accompanying drawings illustrating them, and will then point out the novel features in claims.
In the drawings: Figure 1 is a view in central longitudinal section through a bolt anchor having relativelysoft interior andexterior portions, andan intermediate reinforcing portion of relatively hard metal. Fig. 2 is a view in transverse section therethrough. Fig. 3 is a view in central longitudinal section showing the saine as eniploycd in use, and having been expanded the application of a bolt. Fig. 4 is a view in longitudinal section through a bolt anchor ct the type shown in F10. l, except that the screw threads have 4:been initially formed Sp'ecic'atonof Letters Patent.

of bolt anchors in 'which the hard metal structure is covered within and without with relatively softinetal portions.
Referring first of all to the forni of bolt.
anchor shown in Figs. 1, 2 and 3, the saine will be seen to comprise an expansible tubular shell of relatively soft inietal. and a tubular reinforcement 1G of vrelatively hard'4 metal disposed intermediate the inner and outer walls. thereof. The inner wall is tapered to constitute. a tapered bore 1T, and
the shell is subdivided into separable poi'- tions, by' means of longitudinal slots '1S which extend from the inner endtoward the outer but which, inthis case, do not penetil( Thebtilt which it is desired yto anchor.- is forced into the bore 17 after Vthe shell has been inserted in the hole in thewa'll of stone,`
.Y brick, o r the like as isshown in Fig. 3 whereby threads are formed-upon the interior bore -aiid the shell extended into place as is shown. lThe relatively soft metal of this 'type is caused to .flowsutliciently to cause it to conform to the shape of the hole Aand to forni the threads. It will be readily. understood that the relatively hard metal portion 1 6 acts as a reinforcement for this type of shell and considerably strengthens the same, thus removing one of the disadvantages hitherto' inherent in this type of bolt anchor, namely, the weakness thereof due to the relatively soft metal of which it was necessarily composed. In manufacture, the relatively hard metal portion 16 may be 'inserted in the molds in'which the relatively soft metal portion is cast so that thevliard and soft' metal portions become a single integral structure.

and I have shown the shell as entirely sub-A -.dividedlongitudinally upon the lines 19,.

for a portionof the distance,thelportion'24 at theend where thebolt is admitted being shown 4as Without.' such screw threads Whereby to more readily admit-the bolt.
' In Figs. Sjand 9, Ij have shown a bolt anchor having-Ja relatively hard metal exf terior portion 22, and a' 'relatively softmetal,
interior portion23, but in this case, I have shown the'bore as plain, z.- egwlthont m1- shown the shell as comprising three separate segments longitudinally. subdivided from end. to end. Alining lugs 2i may be employedv inthis type-'s imilartothe lugs vshown in -'.Figs. tand 5." v
In Fig. 10 I have showna type of hard metal bolt anchor in which the tapered Walls 26 are of substantially uniform thickness throughout, .andare provided with exteriorprojections 27 which increase in height'pro- Vgressively from the large to the small end thereof, andiI have 'shown Athis form. of bolt anchor as providedwitha covering 28- Without and `Within offa relativelysoft metal.
In Fig. 11,'4 I have shown asimilar structure except that the outer .covering 29 of relatively soft metal til-ls up the space between the projections so Athat the exterior shell is of a generally cylindricalform.- In this type of bolt, the expansion of the shell will cause theproject-ions to embedv themselves Iin the Walls of the lhole in which the .shell is inserted, While the soft metal ppi'- v-tions will. now to fill up the intervening .Y spaces.- It will of course be understood that -dierent .metals'may be employed' for. the
