This invention .relatesto a frame structure lfor small buildings,` and"particularlyto a joint be' i claims. (ciao-'9.2i

ytween wooden elementsthereof'designedfto be easily and' economically constructed,` and which will adequatelywithstand bending moments` to which'the joint'may besubjected. f i i 'In accordancewith thevpresent invention; it is contemplated to construct smallbuildings-i'from aplurality of standardized frames consistingfof studs and rafters connectedH at the eaves by gusset members which are preferably formed of plywood. Such lframes when `constructed may be readily assembled together in the construction or erection of small buildings and outer sheeting and roofing applied thereover. and economical joint must be provided between the studs and rafters and the connecting gusset member. Such a joint must have the characteristcs of being capable of being easily constructed and assembled together, and be capable of withstanding all reasonable bending moments thatmay be applied thereover. The present invention provides for such a joint.

With the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawing for an illustrative embodiment of the invention, wherein:

Figure 1 is a view in side elevation of the improved frame illustrating the parts thereof as having been connected to each other by the joint embodying the present invention;

Fig. 2 is a partial view in side elevation taken substantially upon the line 2-2 upon Fig. 1;

Fig. 3 is a sectional view taken substantially upon the line 3'-3 upon Fig. 2; and

Fig. 4 is a partial perspective view illustrating the formation of one of the double scarfs forming a part of the improved joint. l

Referring to the accompanying drawing Wherein similar reference characters designate similar parts throughout, the frame shown in Fig. 1 is illustrated as being made up of studs I0, rafters I I, and gusset members I2 which connect and serve to hold the studs and rafters in proper angular relationship to each other. The gusset members are preferably formed of plywood which because of the arrangement of the grain in the laminations thereof, is capable of readily V'vvith- A relatively simple standing the stresses imposed thereon and which in the rafters and studs have their ends oppositely scarred as indicated in. Fig.'l "i,"providingv twooppositely beveled. tongues I3 'and I4. rThe endsfof the gusset'members are similarly scarfed so as to be complementary to the two tongues I3 and'I4. f f g In the formation of these` scarfsthe slopesof the bevels arepreferably about 1:10 andshould never be steeper than 1:6. Glue is applied tothe meeting 4`faces lof the scarfs andthe rafters and studs are assembled with the gusset members by forcing them longitudinally until the opposed scarfs ,resist furtherlongitudinal movement and are disposed in intertting relationship with'the gusset members I2.' The glue is then permitted to harden and dry thus completingthe frame.

When the frames of a small building are assembled together outer sheeting I5 and roofing I6 may be applied thereover.

It will be appreciated that in the above described construction the scarfs on the gusset members are disposed in planes which are at acute angles with the planes of the gusset members and that the plane of each scarf intersects the plane of its respective gusset member along a line which is substantially perpendicular to the length of the member connected to the gusset member by the scarf.

By the improved arrangement it is possible to readily set up woodworking machinery to accurately and easily form the opposed double scarfs on the studs, rafters, and gusset members and by reason of their arrangement, it will be noted that edges on the sides of the scarfs will be in abutting relation with their complementary edges on the scarfs formed on the gusset members. This mutual engagement itself will tend to resist some of the bending moments to which the frame may be subjected. The glue between the opposed faces of the scarfs being in shear when bending moments are applied and due to the gentle slopes of the scarfs there is not only adequate glue present for this purpose, vbut a strong structural arrangement is provided adequately capable of transmitting stresses across the joint. From tests to which I have subjected frames embodying the present invention I find that even when severe stresses are imposed that the studs and rafters do not slide in the plane between the double scarfs demonstrating that Vthe abutting relationship of the scarf edges together with the glue distributed over the gentle slopes of the scarfs serves to adequately transmit stresses across the joint and tend to produce a sturdy monolithic structure.

Various changes may be made in the details of f 3 the construction Without departing from the spirit and scope of the invention as dened by the appended claims.

I claim:
