Abstract: A log for a log home has a plurality of pockets formed within the body of the log. The pockets are filled with foam to enhance the thermal rating of the log. A slot is provided between adjacent pockets to provide a thermal break.

Abstract: A log is provided that has a pair of oppositely directed faces, one of the faces having a pair of tongues separated by a channel and the other face having a pair of grooves separated by a ridge. The tongues, grooves, ridge and channel respectively are dimensioned so as to inter-engage when logs are placed one on top of another. The base of the channel is spaced from the end face of the ridge to accommodate a pair of seals that are maintained laterally spaced apart in the channel so as to define an air space therebetween. A thermal break is thus provided between the seals in the channel to inhibit conduction of heat through the seal.

Abstract: A post and beam building structure has structural members connected by threaded fasteners. The fasteners extend along the axis of the structural members and project into a transverse bore where they are secured with a nut. Manufactured logs are secured to the posts with oppositely directed keyhole shaped wedges that are located in aligned recesses in the post and end face of the log.

Abstract: A dry suit has an outer garment of waterproof material. The fit of the garment is adjusted by pleating the garment and securing the pleat with "Velcro" fasteners spaced apart on the garment. A seal is provided at the neck, wrists and ankles by a cuff overlapping the garment on a support ring and secured with a resilient band.

Abstract: A support for a number of portable machine tools, such as planers, has a planer mounting member with an aperture to provide access to the workpiece for the tool bit of each tool. The tools are releasably secured to the mounting member and can be retained in alignment on the mounting member to perform multiple operations in a single pass.

Abstract: A `log` home is formed by horizontal structural members that are notched at the intersection to form a corner. Springs are inserted in the notch to bias two surfaces of the adjacent logs into engagement so that expansion and contraction are accomodated on the opposite sides of the notch.

Abstract: In a tongue and groove log joint a seal seating channel is formed in the base of the longitudinal groove and a resiliently flexible seal is seated in the seal seating channel. A slot may also be cut in the base to accommodate a reinforcing metal rod. In a butt joint in which a second log underlies the butting logs a seat is formed in the edge of the second log in alignment with the locking slots of the butt joint to receive an end of the locking pin. The seat locks the locking pin against longitudinal movement with respect to the second log. In a wall construction in which the logs of the adjoining walls are connected by an overlapping tenon joint, a first pair of elongated tubular cavities arranged one on each side of a first interface and a second pair of elongated tubular cavities arranged one on each side of a second interface.

Abstract: A machine for cutting logs to provide a dovetail log joint is provided with a number of saw legs which are slidably mounted on carriages, some of which are movable in order to adjust the angle of inclination of the saw blades. This machine permits dovetail tenons to be formed at either end of a log to provide both inside and outside corner joints. All of the necessary cuts can be effected while the log is held in a fixed position, it is only necessary to move the log longitudinally of itself in order to form the tenons at opposite ends. C-clamps are also provided for applying pressure to the log joint during assembly of the joint.

Abstract: A butt joint for ends of logs when built into a log cabin. It involves the formation of opposed channels in the butted ends of the log with a drill so that complementary shaped locking members can be driven into the channels and then wedged into tight engagement therewith to join the butted ends.

Abstract: The invention relates to a machine for end notching logs and to a method for end notching logs so that they can be incorporated into an interlocking corner configuration in a log cabin building. The corner construction is of the 1/2 dovetail configuration and the machine is designed to make one notch, rotate the log and then make a second notch whereby the resulting machine made configuration can be incorporated into a joint that is secure and properly drained.
