WALL-ANCHOR.

To all whom vz'z may concern.-

Be it known that I, IRA B. MALABY, a

citizen of the United States, residing in Philadelphia, Pennsylvania, have inventedtation relatively to the structure fin which it is mounted during the time in which a I screw or collapsing tool is being operated for' the vpurpose of setting up or collapsing it.

The invention also contemplates a novel form of relatively weak side members for the wall anchor whereby they are caused to I f bend at certain. definite points when the' anchor is collapsed in order that they may most advantageously engage the structure on Whichthey are mounte y A furtherobject of the invention is to vprovide a wall anchor particularly designed` Afor use in connecting articles such as curtainl supporting lixturesto sheet metal structures,

- lsuch as metallic window frames, the construction being such that when collapsed its relatively Weak members shall bow in such a manner as to -cause them to engage said sheet metal structure in the position best calculated to permanently retain the anchor in place, and that without injury to the strength of the anchor.

Thesevobjects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in

Figure 1 is a perspective view of a wall anchor'- constructed according to myfinvention; Fig. 2 is an inverted perspective view of the tail end of the anchor shown in Fig. 1; Fig. 3 is a planshowing the anchor as inserted in a properly formed hole in a body of sheet metal; 4Fi 4 is a side elevation illustrating the wal anchor in its collapsed position with aV holding screw mounted therein, and Figs. 5 and 6 are fragmentary perspective viewsillustrating special forms of my invention. ;I

In the above drawings 1 and 2resp'ectively represent the annular head and tail portions of a fastener or wall anchor and these parts are connected by any suitable number (in the prsent case three) laterally Specification of Letters Patent. i

weak members 4 which are outwardl bowed at a point approximately one-thirdy of the distance' `trom the head toward the tail portion. qSaid portions l and 2 leach consists of an annular structure which while it may be made in vsplit form with its ends 16 slightly separated and diverging, is prefer ably continuous',v said ends being brazed or welded, or mechanically connected as shown .in Figs. 5 and 6, 55 In addition the head portion 1 has two In fthatjforni of the invention shown in 75.,

F ig. 5 one ofthe ends of either or both of the parts 1` or 2 is provided witlra dovetail reces andthe other with asimilarly 'formed proje .tion 12 fitting said recess so that said' ends are effectually yheld from separation. g@

In 6 the two ends of the portion 2 are showl; as each having a laterally projecting lug 1- While the helical ring 5 is made with v,

'an edge recess into which both of said lugs t.

The wall anchor above described is par,u g5

'ticularly designed for connecting rigidly tolin material gether two parallel bodies of t such as sheet metal, though obviously it may Ibe used for other purposes, and in practice I prepare the supporting body of materialv o0 for reception `of the anchor by forming in it a circular hole 6 and at twoopposite points of said hole, cutting recesses by pressing out tongues 7 which project .with thein' upper surfaces a definite distance below the under 95 surface of said body of metal 8.' The diameter of the hole 6 is such that it `will permit of passage through it of the tail portion 2 and the side members 4 of the wall anchor,

as well as the head 1, except for the -act 10o that the wings 3 of said head tit into the recesses 9 from which the tongues 7 are pressed and are supported by the latter in such positions that their upper edges as well as the top edge of the head 1 are substantially los flush with the top surface ,ofthe body of Inaterial 8.

The wall anchor is thus firmly supported so that it extends in a line substantially at right angles'to the plane of the sheet 'mate- 1w rIhe tail rial 8 and b suitable means7 such as the tool described and claimed in my patent aforesaid; it may be collapsed so that its various parts occupy the relative positions shown in Fig. -l-. In this collapsing operation the laterally weak side members 4, which as shown, are so made as to bow outwardly adjacent their upper ends, are bent upon themselves in such manner that they are inclined upwardly toward the under su rface of the material 8 and by reason of the initial bend originally given them finally make point contact with it as shown in Fig. Il, so that they are in the best possible position to withstand an outward pull on the helical part 5.

Obviously the anchor can not fall out of the sheet material S since its wings 3 are held by the tongues 7 from passing through the opening therein7 while the bent side members L prevent withdrawal in the opposite direction. The anchor is thus in the form of a socket forthe reception of ascrew or bolt 10 which may be passed through it and threaded into its helical member 5 so as to rigidly connect any desired structure such as thesheet metal fixture l1 to the body 8. rl`he wall .anchor above described is made of a single integral piece of sheet metal properly stamped, rolled up and formed; being made of some structurally strong material suchas steel, having the necessary properties to permit of its manufacture and use without fracture or weakening.

1. A wallV anchor consisting of annular head and tailsections; laterally weak meinbers connecting said sections; and a plurality of oppositely placed wings projecting from the head section in planes substantially parallel to the axis of the anchor.

2. A wall anchor consisting of annular head and tail sections; laterally weak members connecting said sections; with a plural- .ity of tongues bent out of the side parts of the head section and projecting in opposite directions in substantially the same straight line, said tongues lying in planes substantially parallel to the axis of the anchor.

3. The.combination of a body of sheet material having a hole provided with two oppositely' teamed recesses and tongues projecting under saidrecesses; with a wall anchor extending through said hole and including oppositely extending wings entering the recesses and supported on the tongues.

4. The combination of a body of sheet inat'erial having a hole provided with two op- -positely formed recesses and tongues proand tail sections and bent to extend in fiattened U-form at an angle to the axis oi the anchor into engagement with. the underside of said body of sheet material; with laterally projecting wings from the head section of the wall anchor extending within the recesses of the sheet material and prevented by the tongues from passing through the saine.

6. A wall anchor consisting of split annular head and tailvsections of which at least one has its ends permanently connected; with laterally weak members connecting said sections. A

7. A wall anchor. consisting of annular head and tail sections of which the latter is split and has lugs projecting adjacent its ends; with a ring attached to said tail sec# tion and recessed for the reception of the lugs thereof.
