it consists in certain improvements whereby a knock-down structure is produced that may be readily assembled and disassembled, requiring practically no screws or other accessories ,tovretain its parts in assembled relation, and. the joint formed between said parts is exceedingly strongand vdurable. I f My invention is hereinillustrated asembodied in a clothes tree; butit will be understood that it :may be applied to various structures embracing a central pedestal or stafi and radiating members.v

My invention consists, first, in a staff or the like having one end bifurcated in intersecting planes,.andintersecting members (to form said radiating members) one or each of which is notched to receive the other, said members at their crossing portion being fitted into the bifurcations of the stall; second, in constructing the intersecting members in a structure so produced and adapting them to cooperate with the'stafi so that, especially with reference to the removal of material necessary to bifurcate the stall, said structure will be strong andrigid at the joint between the stafi and radiating members; and, third, certain combinations and arrangements, of parts hereinafter pointed out in detail andt finally embodied in the claims. 7 a

In the accompanying drawings,

7 .Figure 1 is a side elevation of a clothes tree embodying my invention; a v

Fig. 2 is a similar vi ew on a larger scale, showing certain (parts in section;

liffig. 3 is an isometric detail view of the sta t Figs. 4,5 and 6 are'sectional views on the lines m-w, g y;and z---a,respectively, of

Figs. 7 and 9 show in side elevation and Figs. 8 and 10 show in plan the two parts of a hook-cluster forming one set of radiating' members; and,

Figs. 11 and 13 show in side elevation and (Figs. 12 and 14' show in plan the two parts of a leg-cluster formingthe other set of radiating members;

The staff a is bifurcated (Fig; 3) longitudinally at eachend, as at b b and c 0. It may be of round, square or any other crosssectlon. I I In the present case there are shown four radiating portions to each hook-cluster and leg-cluster. These four portions in each in stance are produced by two members arranged in intersecting planes and one or each notched (each being preferably halved) intOflJh other.

To form the hook-cluster I provide the members 61 6 each being sawed out," from a plate composed of laminated sheets f, 7 (Figs. 4 and 5) cementedtogether, to produce hooks g; the material of the laminae is preferably wood having the grain in adj oinmg sheets crossing, but it may be'composed of other fibrous material, the object being. to make the members d e proofagainst split-' 'tlng, warping, etc. 7 The memberd has a vertical notch cZ' extending upwardly-there into and the member 6 a verticalnotoh'e extending downwardly thereinto, and they,

are respectively further provided with the vertical recesses d eextending upwardly thereinto.

The members preferably con form in contour, excepting with reference to their notches d e these latter being relatively reversely disposed (one down'and'the other up) the members may be halved into each other as shown in Figs. 1, 2, 4 and 5, the notch of each member receiving the other member, so that the structure produced appears the same in anyside' elevation viewed in the vertical plane of either member.

r Aihook-cluster thus producedis assembled with the upper end of the shaft on by forcing the intersecting or joint portion thereof down into the slots b of the stafl, having firstof course placed the members of the hook-cluster so that they "are in planes corresponding" to "the vertical planes of said .edgeand the other has a similar notch length of the joint.

of the hook-cluster in assembling it with the staff the hook cluster has asto each radiating portion thereof an extended bearing surface affording a substantial bearing on the side of the staff. Thus the jointbetween the staff and hook-cluster isgreatly reinforced;

if any hook gfbe heavily loaded, the strain willcom e against the side of the staff rather than upon its split upper end. V

To form the leg-cluster 1, provide the .Inembersif'jh Each of these'preferably consists of two legs proper z" (j) sawed out of wood andjoined by a web i" (j) formed from a plate of laminated sheets (F ig. .6) cemented together, .said sheets being composed of lcros s grained wood or other suitable/ fibrous materialythe .web 71 (j) is {snugly fittedinto and; glued or otherwise secured in opposite grooves in the legs. 71 (j), One web has an elongated notch 2 extending vert cally. nto it" from its lower extending. into it from its upper end. he Each web is f course thinner than the legs proper i j soi thatthe inner edges m of. the latter, which are 'well extended vertically form shoulders, The members 2' j thus produced,

conforming in contour with each other sub stantially exactlyexcepting for disposition .of their notches.

z j are halved into each other .as show'n in Figs. 1, 2 and 6, the

notch. of each member, receiving the other jjnemb er substantially as'in the case of the members of the hoolncluster. i a v ;A leg-cluster thus produced is assembled with the staff a by placing the latter over the intersection of the leg-cluster so that its bi furcations a register with the webs of the leg-cluster and then forcing the staff downwardly. The width of the notches y' conforms withthe thickness of the webs, so

ithat when the staff 119, in placethe partsjfit snugly' a nd will usually requireno accesseries to keep them together. An important feature of tlns part of my invention is' the bearing surfaces or shoulders m which inthe case of each member of the leg-cluster are spaced apart a distance equal to the. thicknessof the stafl in the fplane ofisaidmcmbenso that the'bifurcated .part of the staff .is abutted on opposite sides by the shouldersm, extending thefull verti- Thus, the "four prongs or projections at the lower part of the stafi formed by bifurcating the stafl at 0 are kept from spreading. apart so that in effect the lower end of the staff, when assembled with the leg-cluster, is as substantial; and ,rigid as ifi giot bifurcated. As to this part of my invention I do not wish to be limited to the structure of the webs as herein described and shown Or to their being.-. ar.ts formed separately from andgattached to the legs proper, the broad idea "claimed being leg" forming members each thinner in its intersectingportion thus fQllhilig the sh lder's' or equivalent,
