Definitions

  • the object of this invention is to provide a re-usuable cartridge for holding mastic or similar material, such as butyl mastic sealant or a hot melt adhesive in the barrel of an applicator gun as used for application of the material for various purposes, e.g. as a sealant to double glazing window units.
  • mastic or similar material such as butyl mastic sealant or a hot melt adhesive
  • a cartridge for holding mastic or similar material and for use in an applicator gun comprises an open ended hollow cylindrical member or sleeve for insertion i the barrel of an applicator gun and providing a bore receiving a piston slidable therein in either direction whereby when the piston is at or near one end of said bore the other end of said bore can receive a body of mastic or similar material- inserted therein for expulsion when heat softened from the bore at said other end thereof by applicator gun operation of the piston, the arrangement being such that, after full expulsion of the material, the hollow cylindrical member can then be either used in a reversed position in the gun barrel with a further body of mastic or similar material inserted in the bore of said member for expulsion by repeat operation of the piston,or the piston can be'returned for similar furthe. operation.
  • the open ended hollow cylindrical member or sleeve 1 is of suitable heat resistant material such as stainless steel which also enables the sleeve 1 to have a smooth interior bore 10 of constant diameter.
  • the sleeve receives slidably therein a piston 2 having a fluid-tight working fit in tne bore 10 and is also of heat resistant material to withstand working conditions of the cartridge in an applicator gun, e.g. at temperatures of the order of 200°C. At the same time it should have an easy sliding fit in the bore 10 and must be of adequate strength.
  • a suitable anti-friction material from which the piston can be made is glass fibre reinforced polytetrafluoroethylene (PTFE).
  • PTFE polytetrafluoroethylene
  • the piston 2 may have a plain periphery as shown or it may be annularly grooved to accommodate one or more sealing rings of heat resistant material such as silicone rubber.
  • the open ends 11,12 of the sleeve 1 receive retaining rings 13 to retain the piston 2 within the bore 10 and also provide fluid-tight seating against end sealing rings 103 in the barrel 100 of an applicator gun.
  • the rings 13 are of sufficient inward radial extent to retain the piston 2 against movement out of the bore 10 yet offer little or no resistance to expulsion of mastic material from the bore 10.
  • End portions of the piston 2 are shown of reduced diameter at 23 to accommodate either ring 13 when the piston reaches an extreme end position in the sleeve 1. This ensures substantially full expulsion of the mastic material from the bore 10 of the sleeve 1 so that the latter is left in a clean condition ready to receive a further body of the material.
  • a cylindrical body of mastic or similar material of appropriate length is inserted into the sleeve through the other end 12.
  • butyl mastic material it is of hard solid form at room temperature and can be readily produced by extrusion to a diameter for a close fit in the sleeve 1 and can be cut to required length as it is extruded.
  • the loaded cartridge or sleeve 1 is then inserted in the barrel 100 of an applicator gun for operation of the piston 2 by air under pressure from the pipe 104 to expel the heat M softened mastic material/from'the open end 12 of the sleeve 1 and through the nozzle 101 of the gun.
  • the sleeve containing mastic material can thus be front end loaded into the gun barrel 100 by removal of the end cap 102 carrying the nozzle 101.
  • the mastic material is softened by the heating coil or coils 110 of the gun about the barrel 100 and preferably the loaded cartridge 1 is pre-heated in an oven prior to insertion in the gun barrel 100 so that the mastic material is already softened and only requires to be maintained in the softened condition with a minimum of further heating by the heating coil 110 before application can be commenced.
  • heating time in the gun and delay before use is kept to a minimum.
  • cartridges may be used, e.g. in succession with a single gun in maintaining more or less continuous operation of the latter, i.e. with waiting loaded cartridges pre-heated in an oven and each empty cartridge reloaded with a cold body of mastic material and then placed in the oven.
  • Cartridges containing heat softened mastic material in the oven and prior to and on loading into the gun should be handled in an upright position with the piston 2 at the lower end of the sleeve 1 to retain the softened mastic material in the latter.
  • the reload the sleeve 1 In order to reload the sleeve 1 it is simply removed from the barrel 100 by removal of the nozzle cap 102 and a further cylindrical body of mastic material inserted into the sleeve bore 10 through the open end 11 up to the piston 2 now at or near the open end 12 of the sleeve 1. After any pre-heating 100 the reloaded sleeve is replaced in the gun barrel/with the end 11 now at the nozzle end of the barrel so that the piston 2 can be compressed air operated for return movement in expelling the softened mastic material from the sleeve 1 and gun nozzle 101.
  • the piston 2 of an emptied sleeve 1 can be returned to its original position and the sleeve 1 reloaded from the same end.
  • the reversible use described above avoids the need to separately return the piston.
  • the invention has the important advantage that disposable cartridges hitherto used to supply mastic material ready for use in a gun are no longer necessary with considerable saving in the cost of supplying the material.
  • the cylindrical bodies or slugs of the cold and hard mastic material can be supplied and handled without individual packaging other than any paper or similar wrapping, e.g. in bulk supply containers.
  • the gun barrel 100 is shown located in relation to an outer casing or jacket 111 of heat insulating material by end rings 109 provided with holes 119 for cooling air flow in the annular space A between the casing and the heating coil 110 about the barrel 100.
  • the heating coil 110 extends for a major part of the length of the barrel 100 to ensure effective heating of the mastic material M in the cartridge sleeve 1.
  • a pistol grip 105 Secured by a cradle portion 115 to the casing 111 is a pistol grip 105 carrying a-slidable trigger 112 for operation of a control valve 120 controlling the supply of air under pressure from a supply hose 130 and via a passageway 113 in the pistol grip 105 to a further passageway 114 and the pipe 104 to the rear of the gun barrel 1 00 through the end can 102'.
  • a rear inclined heel portion 112' of the trigger depresses a plunger 121 of the control valve 120 which by a pin 122 lifts a spring loaded valve member 123 to permit compressed air flow from the passagewayll3 to the further passageway 114 via the interior of the valve body 124.
  • the plunger 121 is depressed in this way it presses a sealing ring 125 into sealing engagement against the valve body 124 and about the pin 122 but on release of the trigger 112 the sealing ring 125 is able to lift to permit venting of excess air under pressure past the upper end of the pin 122 and plunger 121.
  • Issue of mastic material M from the nozzle 101 is obtained as required by operation of the trigger 112 with further control in this respect shown afforded by a tap or cock 107 provided in the nozzle cap 102, the valve member 117 of which has a transverse bore 117 and is rotated by a radial handle 170 to the cap 102.
  • the handle 170 is secured to the valve member 117 as an extension of the latter. Twisting of the handle 170 turns the valve member 117 to open or close the valve 107 to the required extent, such turning movement being shown limited by a screw 108 engaging a part annular groove 118 in the valve member 117 and which also serves to retain the latter in position.
  • the handle 170 also serves for holding the gun in use, i.e. in conjunction with the pistol grin 105 and further provides a handle for unscrewing the nozzle cap 102 from the gun barrel 100 when cartridge removal and replacement is required.
  • the pistol grip 105 also includes a bore 165 for receiving flexible cable 160 for the supply of electric current to the heater coil 110 via a control switch 106 and thermostat 116 which latter controls the operating temperature of the coil 110.
