that at the corners for defining the places where partitions come, and to break up the monotony of long walls, both the corner and partition structures involving the use of log units which are formed either to interlock with themselves or with some other part of the building framing.

Third, to make it possible toeasily and cheaply imitate a log cabin or house, preserving all of the beauty and substantial appearance of a real log cabin or house without the necessity of using logs, and at the same time obtain the advantages of airspaees in the walls and all the other desirable features of frame construction.

Fourth, to use the foregoing corner construction with types of siding other than the mentioned log cabin siding, the foremost value of said corner construction being its superior durability and beautiful appearance as compared with other and known corner constructions, the secondary value of this combination lying in making the building appear as though it was an original log cabin, covered with planed siding throughout the wall space with the exception of the corners.

' Other objects and advantages will appear in the following specification, reference being made to the accompanying drawings in which:

Figure 8 is a perspective view similar to Fig. 1,

Figure 9 is 'a vertical section taken on the line Figure 10 is a vertical section taken on the line ill-i0 of Fig. 8.

Figure 11 is a detail perspective view of a further modification wherein the cut-outs of the log ends are beveled.

Figure 12 is a detail perspective view of a portion of siding, showing how it too is beveled to enter the foregoing cut-outs.

One of the main purposes of the invention as has been indicated already, is to enable the builder to erect an imitation log cabin or house, without having to go to the trouble and expense of obtaining the actual logs with which to build the walls. It should be understood that wherever log is referred to, a natural log is not necessarily meant. An elongated block of wood, whether of round or other cross sectional shape, fashioned to have the general appearance of a log, will be an acceptable substitute.

Thecross log corners, as well as the partitionwall projections, are chiefly instrumental in carrying out the simulation, the effect being com;

plete when the outsides of the walls are covered with log cabin siding. In a wall without partition wall projections, the ends of the siding applied on the wall are cut and fitted into the corner projections of the rectang-ularly abutting walls. In a wall with partition wall projections one end of each piece of siding is cut and fitted into the corresponding partition wall projection (Figs. 1 and 8).

' Further details appear in the drawings to which reference is now made. Both modifications in Figs. 1 and 8 have common features, but consider Fig. 1 first. The building is generally indicated 1, and it isimmaterial whether this is a cabin, house or other structure. The wall framing on one side, (the near side) is indicated 2, and that on the'next side, 3. The framing 2 includes the extreme-end studs 6, 5, and the intermediate pair 6. Said pair has the sidei of a door or other frame near it. The framing 3 includes studs of which 8 is the only one to which reference has I to be made.

The cross log corner is generally indicated't,

and the log partition, 10. The corner 9 is built up as the structure progresses, and consists of units H which are laid upon and interlocked with each other in crossed relationship. All of these units are of identical construction with the exception of. the bottom and top units which may have wall (indicated at 2), making an apparent butnot actual right and left construction.

The unit II has a wall part l3 (Fig. 4), neckl4 and projection l5. The wall part is slabbed off or flattened at 16 (Fig. 5) in the vertical plane. This occurs on the outside of the unit, and its purpose it to provide a flat place on which to lay the siding I! (Fig. 1) whether of the log cabin or other variety. The part slabbed off must correspond to the thickness and form of the siding itself, which is to take its place. The fiat surface must be in alinement with the outside faces of the studdings in the building.

The neck I4 is cross-sectionally square, and its outside surface I1 (Fig. 5) merges into the flattened place H3 at one side, and into a flare i8 at the other side. The inside of the unit H may be fashioned in any way desired, depending upon how the inside of the building is tobe finished.-

What may be called the inside surface IQ of the neck l4 (Fig. .5), inasmuch as it is opposite to H has an inwardly directed flare 20 on one side, and it communicates with what is, broadly, a cut-out 2i (Figs. 4 and 5) on the other side. The bottom 22 of this cut-out is flush with the surface l9 (Fig. 5) Its walls 23 are arc-shaped, and the double arcs which meet at the central point 24, form what is herein conveniently called a double curve. The shapes of the matching double curves (Fig. 2) must correspond exactly to the shape of the siding which they receive. When a number of units H are superimposed in wall-form, the arcs 23 will match in such a way as to provide a recess between adjoining units, as at 25 (Fig. l), for the ends 26 of the siding I! (see Fig. 6 also).

Usually the units II will be round, or substantially so, in cross section, or they may be elliptical as previously suggested. But whatever their form, the necks l4 will interengage (Fig. 6) in crossed relationship. The siding I1 is shiplapped or tongued and grooved at 21, 28 to inter- 1 fit. The wall parts l3 are covered on the outside of the siding, and when the latter is secured by the nails 29, the projections l5 will look. as though they are extensions of the siding, ifiself appearing as so many logs. The inner ends 30 of the units II are secured to the studs 5 and 8 (Fig. 1) in any desired way, generally by nails.

Now as to the log partition ID. This consists 01 units 3| which are laid upon each other in a single plane (Fig. 1). Each partition unit has a wall part 32, neck 33 and projection 34. The neck is formed by diametrically opposite studspaces 35 (Fig. 3) with which the stud pair 6 is interlocked as shown. The units 3| are stacked between the studs 6. The neck 33 adjoins a cutout 36 (Fig. 2), as in the instance of the neck I4 and cut-out 2| of the corner unit.

The cut-out 36 is duplicated on each side of the projection 34 (Fig. 3), and goes in deeply as at 31. Its walls 38 are arced (Fig. 2); coming to-' gether at a. central point 39. The recesses 40 (Fig. 1), resulting from the cut-outs being matched when the units are stacked, receive the ends 4| of the siding precisely as before. The same numeral-29 indicates the nails by which the siding is secured to the studs 6.

So far it will be clear that the siding l1 lines up with the division between the units II and 3| of the corners 9 and partition I 0. This is the truest simulation of an actual log cabin. In Fig. 8 the simulation is not quite so good, but the structure here is adapted to simpler and cheaper steps of manufacture. Identical reference characters are used for corresponding parts in Fig. 1, only having the exponent letter 0. added for distinction.

The neck I4 now referring to only one unit H, adjoins a single-arced wall 42. This is centered with respect to the neck, so that when the end 26 is inserted in the recess the siding H, of which the end, obviously, is a part, will stand in line with the projection I5 and will not be crossed as before. But the sidings I'I are centered upon the division lines between the wall parts I3 as at 43 (Fig. 8), and this makes the joints extra secure.

The same distinction as to the recess. for the siding ends at the partition ll) occurs at 44 (Fig. 9). Each recess is centered upon the projection 34 and so is each siding H Otherwise the arrangement is the same as that already described.

In Fig. 11 thearrangement is on the order of that in Fig. 8, insofar as it concerns the siding running in line with the projections. Corresponding numerals are again used for'identical parts. only adding the exponent letter b. The cut-outs'45 (functionally the same as 36 in Fig. 2 and 44 in Fig. 9) are mere inward bevels. Each piece of siding 11 is similarly beveled at 46' (Fig. 12) to match. Figs. 11 and 12 illustrate the corner structure, but the arrangement at the partition (not shown) will agree.

It should be noted that the log cross corners and partition projections do not apply to any particular kind of siding, although they will be most useful in connection with the so-called log cabin siding shown. The recesses or cutouts in the log projections must in all cases be fashioned to suit the cross section of the siding adopted, and in practice the contour of the cutouts may therefore be any one of a variety of forms andotherwise than circular as shown.
