Abstract: A precision metering, multiple fluid pumping system comprised of a main pump for pumping a primary fluid and an auxiliary pump for pumping a secondary fluid adjustably linked to work in unison with the main pump. The auxiliary pump is linked to the main pump through a rack and pinion gear system connected to an oscillating arm that operates the auxiliary pump simultaneously with the main pump. The auxiliary pump is infinitely adjustable over a selected range by varying the connecting point of the auxiliary pump to the oscillating arm. The connecting point is varied by a worm screw adjustment that provides precision adjustment and metering of a secondary fluid. The system also includes a clutch mechanism between the auxiliary pump oscillating arm and a rack and pinion gear system to disengage the auxiliary pump for priming. An additional feature is the inclusion of a leak detection system in the form of a drain conduit connected to a clear container that visibly indicates when seals in the auxiliary pump may be leaking. When fluid leaks past a main seal in the auxiliary pump, it is collected in the clear container visibly indicating the seals need replacement.

Abstract: A system for purging fluid delivery systems such as paint spray guns with non-toxic, non-polluting cleaning solvents. A sealed tank is provided for storing a cleaning solvent with air pressure applied to deliver the cleaning solvent through a coaxial hose to a slide selectable valve. Pressurized air is also connected to one of the conduits of the coaxial hose. Spray guns or fluid delivery systems are cleaned and purged by first releasing the cleaning solvent in the passageways and then quickly switching to a blow-down mode on the slide selectable valve to discharge the cleaning solvent from the spray gun passages.

Abstract: A pail mounted pump system having dual reciprocal pumps and pail cover in an integral design. The pump and pail cover are constructed in a single unit with a built-in intake siphon tubes. This arrangement provides dual pumps pumping the same fluid which keeps the system pumping should one of the pumps fail. The pail cover is formed with a recess and mounting holes for mounting a pump. A skirt on the cover has a flange on its inner surface forming an annulus which seats securely on the pail rim. A recirculation/agitation system is provided by a hose connected through a valve to the pump outlet recirculating fluid back to the pail through an aperture in the cover.

Abstract: A plural component spray gun which can be used as an air atomizing gun for atomizing material at the nozzle for external mixing with a catalyst, and, which is convertible to airless operation. The spray gun has a nozzle body which incorporates passageways for delivering atomizing air and a fluid component to a mixing chamber at the outlet to one of a plurality of nozzles attached to the nozzle body. To convert the spray gun to airless operation, the nozzles are removed, and a sleeve inserted in the air atomizing chamber. One of the nozzles is replaced with an airless type and they are reattached to the gun body. The replaced nozzle has a centrally located annular flange which extends into the air atomizing chamber to hold the sleeve insert in the chamber to seal the air passageway. The centrally located annular flange on the replaced nozzle also includes an annular cavity, into which an insert having an orifice restriction can be inserted for increasing the velocity of the component during airless operation. The spray gun is easily converted back to air atomizing operation by removal of the airless nozzle and sleeve sealing the air passageway and replacement with the air atomizing nozzle.
Abstract translation: 一种多组分喷枪，其可以用作用于喷嘴处的雾化材料的空气雾化枪，用于与催化剂进行外部混合，并且其可转换成无空气操作。 喷枪具有喷嘴主体，该喷嘴主体包括用于将雾化空气和流体部件传送到出口处的混合室的通道，其连接到喷嘴主体的多个喷嘴中的一个。 为了将喷枪转换成无气操作，喷嘴被拆除，套筒插入空气雾化室。 其中一个喷嘴更换为无气型，并将其重新连接到枪体。 替换的喷嘴具有中心定位的环形凸缘，其延伸到空气雾化室中以将套筒插入件保持在腔室中以密封空气通道。 更换的喷嘴上的中心定位的环形凸缘还包括一个环形空腔，可以插入具有孔口限制的插入件，以在无气动作期间增加部件的速度。 通过移除无气喷嘴和套筒密封空气通道并用空气雾化喷嘴更换，喷枪容易转换回空气雾化操作。

Abstract: A dispensing gun for mixing, then pouring or spraying reactive components, many of which have high viscosity. The gun consists of a material or mixing head or body having a plurality of chambers or canals connecting input ports through passageways and valves in close coupled relationship to a mixing chamber. Valves for purging or flushing the mixer body are also closely coupled to the input parts and mixing chamber. A rotatable mixing grid and mixing sleeve are removably retained in the mixing chamber and can be easily removed for adapting the gun for use with a static or motionless mixer. A high torque pneumatic motor located on the mixer center line drives the mixer grid in the mixing chamber. The mixer body has three or more material inlets, four valves, and a connection for the pneumatic motor all closely coupled to the mixing chamber. The arrangement of valves and pneumatic motor connections permits the device to be easily adapted for completely automatic operation. The trigger for the gun provides built-in lead and lag adjustments for materials having different viscosities and/or pressures. The purging system provides a connection for a coaxial hose, permitting air and/or solvent flushing of the entire mixing gun body. The nozzle is easily replaceable to permit pour or spray configuration.
