Summary:1223854 Making timber frames J HURN, C R F KING and D R DEANE 16 Aug 1968 [23 Aug 1967] 38789/67 Heading B5L A method of manufacturing a timber frame comprises assembling parallel head and sole stringers 10, 11 and nailing a stud 1 transversely between them at a datum line X-X, Fig. 8b; moving the stringers logitudinally by a conveying means over a predetermined distance; clamping the stringers after they have been so moved; inserting a second stud 2, Fig. 8f between the stringers on the datum line X-X, clamping the stud 2 in position, and nailing the stringers to the opposite ends of the stud 2. The term "nailing" is defined as including any mechanically equivalent fastening operation, e.g. fastenings made by dowels, staples, woodscrews, pronged plates of corrugated strips. The apparatus described for performing the method comprises two parallel sets of guide rollers 42, Fig.1, carried by channels 27 which are carried by a fixed bed of the machine and are adjustable towards and away from each other by screw means 25, and carriages one on each channel 27 and slidable therealong by rotation of leadscrews. Fluid operated clamps A, C, D, G are fixed to the channels 27 and clamps B, F to the carriages. In operation of the machine the stringers 10, 11 are fed manually along the sets of rollers 42, shown as fences 100 in Figs.8b and 8f, until their ends abut pneumatically actuated stops H. The distance apart of the stringers is adjusted by the screw means 25. The clamps A, C, and D are operated to engage the stringers. A stud 1 is positioned between the stringers on line X-X and clamped in position by clamps E against stops H, Fig.8b. The stud is then secured to the stringers, e.g. by manual or automatic nailing. The clamps B and F are then operated, the clamps AC, D and E released, the stops H lowered and the carriages advanced the desired distance. Clamps ACD are again engaged and clamps B and F disengaged. The carriages are returned to their initial position. The stops H are partly raised, and a second stud 2 is inserted and held in position by clamps E, Fig. 8f position. The stud 2 is then nailed in position and the sequence of operations is repeated until the frame is completed. The operation of the machine may be from a programmed punched or recording tape. Means may be provided at the line X-X for marking the frame for further operations.
