Another salient feature of the invention is the I adaptability with a slight modification of using the same principle of a cut blank for thefolding;

and interlocking means for box containers, in which the upper interlocking tabs are printed for the chimney, windows and doors printed on the outside panels, these ornamental features printed thereon "may be to suit any type or design of house desired; The printed housefeature may apply also to the bird-house, but it has been found that plain wood finish colors are best for the exterior panels of the bird-houses, so as to match in=with the trees secured to.

Other features of theinventionwill appear as the description proceeds in the following specification accompanied by the annexed drawings,

Referringto the drawings particularly tothe cut blank shown in Figure "l, the numeral fl des ignates the intermediate front panel havinglaterally. suitable folding crease lines 2 and 3 interconnecting obliquely to side, panels i and 5, with bottom edges 4 and 5 the side panels having gable-like apex or vertex portions ,6 and],

respectively. The side panels 4 and 5 have also, crease lines 8 and 9 interconnecting to rear end flap sections l0 and H havingshoulder portions Ill N and H li respectively, andupper and lowertabs l2 and 12 l3 and l3, respectively, the tabs being provided with holes =14 and'lfl therein. The front panel {has transverselyma lower horizontal crease line 16 interconnecting" to a bottom panel l'lhaving also a crease line 18 interconnecting to rear: panel l9 1 provided with OFFICE I v shoulder portions I9 and a tab 20 which has a hole 2| therein. The front panel I has also transversely a further horizontal folding, crease line 25.

which is provided with a keeper-slot 3L The front panel I is further providedwith a suitable ingress opening 32 and a small hole 33 through which a perch stick 3.4 asshown in Figure 1, may

- be inserted-to a similarhole 33" in the side panel 5, so the end of the perch-stick may be near the opening 32 for use of the mother bird tofeed This description of the cut blank as shown in 1 Figure 7, may be appliedto Figures 1, 2, 3, 4, and

5, wherein the blank is assembled in a set up for The bottom panel H is provided pose, terminating in edges ll and ll thatyconfit and contact adjacent the creases 8 and 9,.of

The roof panel 26 has cut slits 25 and 26* corresponding to the oblique edges ii and M of the vertex portions 6 and l of the side panels 4 and 5, in order to provide the eave portions E on the side of the house.

' In Figures 8 and 9, a bird-house is shown em-;

bodying the same folding and set-up operations as the bird-house hereinbefore described, in which the same numerals in the description thereof will be primed for similar parts. In Figure 10 the cut blank shows the crease lines 2', 3, 8, and 9' in parallel relation to each other, thereby providing panels with right angle corner portions, thereby allowing square or oblong panels.

Figure 11 showsacandy box similar to the house form shown in Figures 8 and 9 and made from a blank similar to that shown in Figure 10, the tabs l3 and l3 and the openings 32, 33" and 33", and 6&3 being omitted, the tabs 92" and 12" being printed to resemble the. chimneyof a house, and the outer surfaces of the panels being printed to show a window W, a door D, and roofing 28. ,3

It will be understood that in the blank shown in Figure 10 the front, side, rear, top and bottom panels 5', a, 5', ill" and H, respectively, have 1 similar folding 01' creaselines 2', 3', 839, l6,

I8, 25 and 26', and interlocking tabs i2, i2" and 25!,and keeper-slot 3! as the blank shown in Figure 7, are all similar in construction and purpose although the size and shape of each may lower tabs Stand l3 and similar primed tabs of.

the modifications shown in Figures 8, 9, l and 11, for example, the securing of the tab portions has been shown for. nailing through the holes M, I4, l lfland M for securing to the support the fioor panels l! and ll" in Figures 7 and 10,

may or'may not be used to insert the tabs it and I3. therethrough, andthe tab 20 of the panel: l9 then assumes the rearward tab in place of the tab E2 of the panel H, as shown in Figure 6; If the slot 59 as shown tends to Weaken the bottom ll and H the slot 60 may be reduced in width and also the tabs l3, l3, l3", and '3" reduced in width accordingly. It is. a matter of preference in folding the end flaps Ill, ll and the rear panel it and end flaps I0, I l and rear panel l9 to suit whichever is preferable.

It is to be understood I do not wish to confine myself to any exactness ofany detail of shapeor design, material or construction, and reserve the right to make any alteration thereof that my come within the spirit of this invention andthe one of said panels being provided with a keeperslot, said panels including rear flap ends and a rear panel having tabs overlapping in a threefold formation and snugly secured into said keeper-slotof one of said gable roof panels thereby providing an assembled house structure without any corner bracing therewith.

2. A collapsible house structure, comprising a front panel provided with a suitable ingress opening, interconnecting to side panels having gablelike apex portions, said side panels having lateral creases interconnecting to end fiap sections provided with upper and lower tabs therewith, said frontv panel having transversely a lower crease interconnecting to a bottom panel which has also transversely a crease interconnecting to a rear panel provided with shoulder portions and a tab therewith, said front panel having transversely an upper crease interconnecting to a front roof panel having also transversely a crease interconnecting to a rear roof panel having a similar crease interconnecting to an end eave flap section, said roof panel and cave flap section provided with a keeper-slot at their interconnecting creased portion, a small hole adjacent said ingress opening of said front panel and a corresponding hole in one of said side panels adjacent thereto whereby a perch-stick may be inserted diagonally through said holes and adjacent said ingress opening, all of said interconnecting panels forming a complete house structure, whereby said end flap sections with their tabs and the rear panel overlap each other in a three-fold formation whereof the tabs are secured in a close fit into said keeper-slot and firmly interlocked therein.

3. A collapsible house structure, comprising a plurality of interconnecting creases and panels forming the front, rear, sides, roof and floor panels of said house structure, one of said roof panels provided with a keeper-slot, said interconnecting panels including rear flap ends and a rear panel having shoulder portions and tabs laminated in a three-fold formation firmly interlocked and snugly secured in a close fit into said keeper-slot of the top roof panel.

4. A collapsible house structure of the character described as defined in claim 1, said front, sideand rear panels being of an oblique design whereby said interconnecting creases of said panels diverge upwardly at an obtuse angle from the bottom planeof the intermediate front panel.

5; A blank having a plurality of parts associated'with each other by creases, said parts including elements that constitute a floor, a roof, and walls of a house structure when said parts are turnedon their creases, the roof elements including parts that form front and rear gable roof panels and a keeper-slot in one of them, said elements including an element that forms the front wall, two-side-wall-forming elements associated by creases with the front-wall-forming element, a bottom-forming element associated by a crease with the front-wall-forming element, and a rear-wall-forming -element associated by a crease with the bottom-forming element, the blank also including rear flap ends, each associated by a crease with one of the side-wall forming elements, the rear-wall-forming elements and the rear flap ends having integral tabs so constructed that, when the blank is bent to form a house, said tabs will overlap and fit tightly into said keeper-slot.
