Abstract: A versatile tiltable vehicle lift capable of supporting a vehicle at a desired height. In its lowermost position, the lift tilts downwardly, thereby enabling a vehicle to be driven onto the lift. The tiltable feature of the lift eliminates the requirement that the device be retractable below floor level. The tiltable vehicle lift has an upper treadway frame for receiving and supporting a vehicle. An elevation means, typically a hydraulic cylinder, is pivotally connected between the rearward legs and the treadway frame. The tiltable vehicle lift is provided with a locking mechanism that safely maintains the vehicle lift at a desired height. The locking mechanism is comprised of an upper lock bar and a lower lock bar which may be engaged at any desired height of the vehicle lift. A means for disengaging the locking mechanism is provided so that the vehicle lift may be lowered.

Abstract: A method for transporting one tractor and semi-trailer combination on another tractor and towed semi-trailer which comprises reducing the wheel base of the transported tractor-semi-trailer combination, positioning the transported tractor and semi-trailer on the transporting semi-trailer with the tractor at the rear of the transporting semi-trailer and facing rearwardly, and with the rear end portion of the transported semi-trailer elevated from its normal position and extending over the cab of the towing tractor used for transport. Apparatus is provided on a tractor-semi-trailer combination to facilitate the described wheel base shortening, and the elevation of the rear end portion of the transported semi-trailer.

Abstract: Method and machine and a log product for log house construction includes improvements in apparatus to shape, and finish the logs, divide into halves or quarter sections for tongue-and-groove assembly construction of floors, walls, or ceiling appurtenant to the log house. Equally-spaced holes between the tongues and grooves provide additional functional uses for utility lines or vertical supports as needed.

Abstract: A machine for processing wood logs for construction of log houses. The machine includes a power feed to load the logs into a self-centering device. A carriage assembly is centered about the log and the log is mounted in the carriage on powered centers so that the log can be rotated. The carriage travels longitudinally on tracks past one, or a plurality of cutters, which as the log rotates cuts the log down to a selected diameter. After the log is cut to diameter it is again passed longitudinally along the tracks and two cutters are positioned at equal distance above and below the axis of the log to cut tongues and grooves on the top and bottom of the log, respectively. Means are provided for cutting a saddle notch underneath the log, to cut the logs to precise length, and to cut a vertical notch in each end for the purpose of joining logs end to end. Means are provided for rapid removal of the chips cut from the logs.
