Abstract

Abstract A pneumatic dispenser gun for two part viscous materials comprising two parallel containers containing the two materials and a pneumatic cylinder 12 whose axis is parallel to the axes of the two containers and which contains a piston 15 having symmetrically mounted piston rods 17, 18 extending through the end wall of the cylinder into the containers to expel the contents of the two containers simultaneously through a common outlet passage. A further rod 19 extends from the piston parallel to the piston rods but outside the containers to provide an indication of the amount of contents remaining in the containers and a handle for returning the piston to its initial position.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 103 words
A pneumatic dispenser for a multi-part viscous material comprising a pneumatic cylinder containing a piston carrying parallel piston rods extending from one end of the cylinder, a plurality of parallel cylindrical containers mounted on the cylinder and extending away from the said one end of the cylinder respectively to contain the parts of the material with their axes parallel to the axis of the pneumatic cylinder and with the piston rods extending respectively into the containers, and a further rod carried by the piston and extending from the said one end of the cylinder parallel with the piston rods and alongside the containers.
Claim 2
Dependent Claim 103 words
A pneumatic dispenser for a multi-part viscous material comprising a pneumatic cylinder containing a piston carrying parallel piston rods extending from one end of the cylinder, a plurality of parallel cylindrical containers mounted on the cylinder and extending away from the said one end of the cylinder respectively to contain the parts of the material with their axes parallel to the axis of the pneumatic cylinder and with the piston rods extending respectively into the containers, and a further rod carried by the piston and extending from the said one end of the cylinder parallel with the piston rods and alongside the containers.
Claim 3
Dependent Claim 25 words
A dispenser as claimed in claim 1 in which the containers are connected at their ends remote from the cylinder to a common outlet passage.
Claim 4
Dependent Claim 32 words
A dispenser as claimed in claim 1 or claim 2 in which the containers are formed by separate cylindrical cartridges and the cylinder comprises a plurality of side-by-side mountings for the cartridge.
Claim 5
Dependent Claim 27 words
A dispenser as claimed in claim 3 which includes a pivoted yoke having retaining means at its forward end to releasably retain cartridges within the mounting means.
Claim 6
Dependent Claim 29 words
A dispenser as claimed in claim 1 or claim 2 in which the containers are provided by a common cartridge and the cylinder comprises a mounting for the cartridge.
Claim 7
Dependent Claim 36 words
A dispenser as claimed in any of the preceding claims in which the forward end of the pneumatic cylinder is closed by a transverse wall providing sliding bearings for the piston rods and the further rod.
Claim 8
Dependent Claim 30 words
A dispenser as claimed in any of the preceding claims in which the further rod carries a handle for returning the piston to the rear end of the pneumatic cylinder.
Claim 9
Dependent Claim 33 words
A dispenser as claimed in any of the preceding claims in which the axes of the piston rods are evenly spaced around a circle with the axis of the pneumatic piston as centre.
Claim 10
Dependent Claim 20 words
A dispenser as claimed in any of the preceding claims in which there are two piston rods and two containers.
