US 4,067,479 A · Two part material meter-mix dispenser apparatus

Abstract

A hand held two part material meter-mix-dispenser apparatus has a hand held body including a base mounting an air driven cylinder means in association with a double plunger assembly and a pair of cartridge receiving barrels with means for hingedly mounting the barrels to the base so that when in hinged open position, the barrels are positioned to easily receive a pair of cartridges containing different parts of a material to be mixed and when moved into hinged closed position automatically locate such cartridges in association with the double plunger assembly for simultaneous exuding of the materials of the two cartridges through a mixing head mounted on the apparatus body. Air driven mixing means are provided in the mixing head to dynamically mix the materials under pressure being forced through the mixing head via disposable conduits running from the two cartridges during operation of the dual plunger assembly. The mixing head assembly is a disposable component of a kit including disposable material containing cartridges and conduits which are easily assembled and retained upon the apparatus body for metering, mixing and dispensing a material comprising two initially separately stored parts.

Dependent claims

A hand held two part material dispenser apparatus comprising:

a hand held body including a base mounting a single air driven cylinder means and a double plunger assembly in operative relation for actuation of said plunger assembly by said single cylinder means;
a pair of cartridge receiving cylindrical barrels and means for hingedly mounting each of said barrels to said base, said barrels each being adopted to receive a separate material dispensing cartridge when in hinged open position and positioning two such cartridges relative to said plunger assembly when said pair of barrels are in hinged closed position for simultaneously exuding the materials of such two cartridges upon operation of said single cylinder means;
air driven mixing means mounted on said base and including a material receiving housing having two inlets and a single outlet for mixing materials received in two parts through said two inlets and dispensing a mixture thereof through said outlet;
flexible conduit means for connecting said two cartridges to said two housing inlets;
and
air supply means including a single air line and means for selectively connecting said line to said air driven cylinder means and said air driven mixing means for air pressure operation of said plunger assemby and mixing means from a single air line power source.

A hand held two part material dispenser apparatus adapted to use disposable material containing cartridges, mixing head and interconnecting conduits comprising:

a pair of cartridge receiving tubular barrels, each open at opposite ends to receive an individual separate material containing and dispensing cartridge through one end thereof with a nozzle end of the cartridge protruding through the opposite end of each said barrel and with a plunger portion of such cartridge facing said barrel one end;
a double ram assembly including a pair of ram heads mounted on the ends of a pair of ramrods connected for concurrent movement and means for mounting said ram assembly to place said ram heads in operative driving relation to said cartridge plungers;
air operated cylinder means for operating said ram assembly;
a mixing head mounting and retaining means for removably mounting and retaining a mixing head;
air motor means for operating said mixing head;
and
air control means for selectively controlling air pressure from a source thereof to said cylinder means and motor means, whereby a pair of material containing cartridges, mixing head and interconnecting conduits may be assembled to said dispenser apparatus for metering, mixing and dispensing two part materials, thereafter removed from said apparatus for disposal with the apparatus being reusable with replacement cartridges, mixing head and interconnecting conduits.
