Definitions

  • This invention relates to a press for inserting cleats into framework joints more particularly but not exclusively in wooden framework joints, and to an improved cleat for use therewith.
  • Aim aim of the present invention is to provide a press for inserting cleats into framework joints and an improved cleat for use with such presses which overcomes the above disadvantage.
  • a press for inserting a cleat into a joint of a framework comprising a head having releasable clamping means to hold at least two framework sections in a jointing position, a power operated cleat inserting tool for receiving the or each cleat to be inserted into a preformed slot in the framework joint, the cleat insertion tool being movable between an insertion position and a retracted position by a power operating means.
  • the power operating means is a pneumatically operated piston and cylinder assembly.
  • the cleats are fed to the press in pairs from a magazine.
  • the press can be manually or automatically operated.
  • a cleat comprising a flat plate rounded at one end, two grooves extending along the longitudinal axis of the cleat and at least two ribs on one side thereof which diverge towards the rounded end, the divergent ends of the ribs being tapered to form a cutting surface.
  • the press for inserting cleats illustrated in Figs. 1 to 3 comprises a supporting frame 1 on which is mounted, at one end, two pneumatically operated clamping members 2 positioned over two locating jigs 3 to receive two wooden window sections 4 and 5 having mitred ends.
  • the mitred ends are each preformed with arcuate parallel slots 6 and 7.
  • the mitred ends of the window sections are laid in an abutting position in the jigs 3 and the pneumatically operated clamping members 2 are actuated to clamp the window sections into a right-angled corner joint.
  • Cleats 8 are fed from a magazine (not shown) or positoned manually by the operator at the front of a cleat inserting tool 9 connected by a yoke 10 with a pneumatically operated piston ram 11 to reciprocate the tool in the directions of the arrows 'B'.
  • the forward stroke of the tool inserts the cleats into the preformed slots 6 and 7 and presses them into the window frame sections 4 and 5 to form a rigid and robust corner joint.
  • the return stroke of the tool removes the cleat inserting members to their rearmost position ready to receive further cleats.
  • the clamping and cleat inserting tool is automatically operated from an air supply under the control of the machine operator so that immediately the cleats have been inserted in the window sections to form the joint the clamping members 2 are automatically released allowing the jointed window sections to be removed from the jigs 3.
  • the press has the required safety devices to prevent operation of the cleat inserting tool until the window sections are located in the jigs and clamped in position.
  • Fig. 4 illustrates a second embodiment of the cleat press having two clamping heads 21 and 23.
  • the left hand head 21 is fixed to one end of a rail 22 while a movable head 23 is located at the right hand end of the rail.
  • Each press head is constructed in the same manner as the embodiment described in Figs. 1 to 3, only the clamping members 24 and jigs 25 of which are shown.
  • three mitred window sections shown in chain-dotted line are located in position in the jigs 25 and are clamped by the members 24.
  • the movable head 23 is linked pneumatically with the fixed head 21 and can be operated to move the movable head 23 towards the fixed head, depending upon the length of the window section 26.
  • the movable head 23 is clamped to the rail 22 and a cleat or pair of cleats are inserted in the preferred slots in the window sections.
  • the press for inserting cleats may comprise four heads, as illustrated in Fig. 6. Each head is constructed and operated in a similar way to that described in Figs. 1 to 3.
  • the four heads 26, 27, 28 and 29 are mounted on rails 30, 31, 32 and 33 respectively.
  • the two heads 22 and 23 are mounted to move along rail 31 while the heads 21 and 24 can move along the rail 33. Both rails 33 and 31 can then move along rails 30 and 32 providing a complete adjustment of the clamping heads to the relative length of the window sections.
  • All the four heads are connected by a pneumatic system so that they can be operated individually or simultaneously to suit particular requirements.
  • the press can be automatically controlled by a computer programme. This would include computer controlled mechanisms to cut and mitre the length of window sections to the required length, the positioning of the cut window sections in the jigs and the clamping of them in position, and the operation of the feeding of the cleats from the magazines and insertion into the window sections to form the framework.
  • two and four headed clamping presses can only join together mitred window sections which are pre-machined to form a 90 o corner joint.
  • the improved cleat shown in Fig. 7 is preferably made of a flat plate of metal but may be made of a rigid plastics material.
  • the cleat has curved nose portions (12) at one end joined by a flat end face 13.
  • Each side of the cleat has two grooves 14 with parallel inner walls 15 and diverging outer walls 16 formed in the side surfaces of the cleat.
  • Along the outer walls 16 are ribs 17 and 18 with angled ends 19 and 20.
  • the end of the cleat opposite to the round nose portions 12 is cut to a V-shape to correspond to the angled shape of the mitred window sections 4 and 5.
  • each of the window sections 4 and 5 are cut to an angle to form a mitred joint with two preformed grooves 6 and 7, the groove ends are placed together to form two parallel slots into which the cleats are pressed.
  • the diverging ribs 17 and 18 form grooves in the wooden window sections and displace wood in their path, into the grooves 14.
  • the curved nose portion 12 abuts against the curved ends of the grooves 6 and 7 aligning the V-shaped ends of the cleats with the angled inner walls of the mitred window sections 4 and 5.
  • the diverging ribs 17 and 18 on the sides of the cleat engage the window sections pulling them together to produce a very strong secure joint.
