Definitions

  • This invention relates to a dispenser gun according to the preamble of claim 1.
  • Such guns are known from GB-A-1264311.
  • the guns are used for dispensing viscous materials which may be of a thick liquid or a pasty nature, for example mastic caulking materials.
  • Such guns often include rod advancing mechanisms of the kind including a one-way gripper arranged for reciprocation longitudinally of the the axis of the rod and arranged to tilt relative to the axis of the rod between a rod-gripping position on the forward stroke of reciprocation of the gripper to advance the rod and a rod-release position on the rearward stroke of reciprocation of the gripper to allow the gripper to return without moving the rod.
  • dispensers for viscous materials are known and one particular example is A-described in GB-A-12643ll.
  • a gun for expressing liquid or semi-liquid substances including a body, a rod mounted on the body for axial movement thereon, and a movable oneway gripper mounted on the body and arranged to advance the rod in the manner described above.
  • the rod is of circular cross section and the gripper has a circular aperture through which the rod passes fairly freely.
  • a further effect of high loads with the previous guns described above is that the edges of the hole through which the rod passes and which engage the rod are deformed.
  • the effect of this is that the gripper has to be tilted to a greater extent before gripping engagement between the gripper and the rod is achieved so that the initial travel of the member producing the tilting (such as a trigger) is wasted and less material can be dispensed on each forward stroke of the gripper.
  • a dispenser gun for expressing liquids has a body, a parallel-sided piston rod of circular cross-section mounted for reciprocation on the body and a rod-advancing mechanism comprising a gripper plate with a parallel-sided hole of circular cross-section through which the rod passes, and is characterised in that the mouth of the hole on one side of the gripper is bounded around at least part of its periphery by an arc of an ellipse, the geometry being such that on tilting of the plate the elliptical arc engages the rod along a substantial length of the arc.
  • the gripper plate is parallel-sided there may be a similar indentation on the other side of the gripper and positioned diametrically opposite to the first indentation.
  • each indentation where provided may be a parallel-sided groove running into the hole or alternatively may be a part dome-shaped depression which overlaps the hole.
  • the width of the indentation is approximately equal to the diameter of the hole.
  • the gripper is preferably made of metal by a sintering process but may be produced in other ways, for example by lost wax casting.
  • the gripper may have a thickness which is approximately equal to the diameter of the hole.
  • Figure 1 is a side elevation of the dispenser
  • Figure 2 is a rear elevation of the gripper of the dispenser shown in Figure 1;
  • Figure 3 is a side elevation of the gripper
  • Figure 4 is a rear elevation of the gripper
  • Figure 5 is a cross section on the plane V-V in Figure 2.
  • Figure 6 is a view similar to Figure 2 of a modified construction of gripper.
  • the dispenser shown in the drawings, and particularly in Figure 1, comprises a barrel 1 to contain the material to be dispensed and having at one end a nozzle assembly 2 and at the other end an operating mechanism 3 by means of which a piston rod 4 can be advanced step by step along the axis of the barrel 1.
  • the operating mechanism comprises a body portion 5 having a depending stock 6 which can be grasped in the hand and to which is pivoted a trigger-like member 7.
  • a stud 11 On the side of the pivot 8 of the trigger member 7 remote from the finger-engaging portion 9 thereof is a stud 11 which engages an apertured plate 12 through the aperture in which the piston rod 4 passes with some slight clearance.
  • the upper edge of the plate 12 rests against a shoulder 13 on the body portion 5 and the plate 12 is biased to the right as seen in the drawing by means of a compression spring 14.
  • the piston rod also passes through a second apertured plate I5 which engages against a boss 16 on the body 5 and which is biased to the right as seen in the drawing by means of a compression spring 17.
  • the plate 12 moves forward with the piston rod to advance the piston in the barrel 1.
  • the rod slides through the plate 15 which is tilted slightly about the stud 16 to allow free movement of the rod 4 through the aperture of the plate.
  • the spring 14 returns the plate 12 to the position shown in Figure 1, the plate sliding along the rod 4 which is prevented from moving in the reverse direction by the plate 15 resuming the position shown in Figure 1 and gripping the rod 4.
  • the return movement of the plate 12 under the action of the spring 14 also returns the trigger member 7 to the position shown.
  • the gripper 12 is shown in greater detail in Figures 2 to 5 and it will be seen that it consists of a generally key-hole shaped thick plate which is made of sintered metal and in the broad part has a cylindrical hole 21 extending through it from the rear face 22 to the front face 23, the axis of the hole being normal to the two surfaces.
  • the rear face 22 is formed with a shallow groove 25 whose width is equal to the diameter of the hole 21 and which has a base which is an arc of a circle.
  • the groove extends from a closed end 26 and runs into the hole 21 thus providing an intersection between the groove 25 and the hole 21 which is in the form of a non-circular arc 27.
  • the front face 23 is formed with a groove 28 which is of identical form but which runs into the bottom of the hole 21 by comparison with the groove 25 on the rear face which runs into the top of the hole.
  • the rod 4 is firmly gripped and considerable force can be applied to the trigger member 7 and hence through the pin 11 and a plate 12 to the rod 4 and hence to the piston in the barrel 1, thus increasing pressure on the contents in the barrel and causing it to be expressed through the nozzle 2.
