Abstract: A dual component pumping system comprised of a double-acting air motor alternately driving reciprocal pumps. Mechanically operated pilot valves activate a spool valve which reverses the air motor operation. Each pump has an inlet connected to a separate fluid component supply tank and an outlet connected to a spray gun through flexible hoses. A valve switching arrangement permits switching from one fluid to the other. The valve switching allows spraying of a fluid received from one pump while the other pump is in a bypass mode and recirculates fluid from its supply tank.

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 roving cutting steering mechanism for use with a plural component spray gun for producing fiberglass reinforced products. A roving cutter is mounted on a plural component spray gun with a support plate and a bracket which is easily vertically adjustable by loosening a bolt mounting the bracket on the gun body. Horizontal adjustment is provided by a cam fitting a slot in the end of a bracket which shifts a mounting plate horizontally. The roving cutter being mounted on the plate is steered to align the path of cuttings ejected from the roving cutter to the optimum position for intersecting the fluid path of material being sprayed by the spray gun. Quick easy adjustment both vertically and horizontally of a roving cutter allows optimizing the mixture of roving cuttings with a spray of plural components being applied to a surface.
Abstract translation: 一种用于生产玻璃纤维增强产品的多组分喷枪的粗纱切割转向机构。 粗纱切割机安装在具有支撑板和托架的多部件喷枪上，托架通过松开将托架安装在枪体上的螺栓容易地垂直调节。 水平调整由凸轮装配在支架的端部的槽中，该槽将水平地移动安装板。 安装在板上的粗纱切割器被转向以使从粗纱切割器喷射的切屑的路径对准由喷枪喷射的材料的流体路径相交的最佳位置。 粗纱切割机的垂直和水平的快速调节允许通过施加到表面上的多个部件的喷雾来优化粗纱切片的混合。

Abstract: A modular multiple-fluid component selection and delivery system comprised of a main block having a centrally located main passageway intersected by a plurality of secondary passageways. Plug valves are inserted in bores in the block which intersect each respective main and secondary passageway. A valve at the entrance to the main passageway permits flushing the system with a solvent for cleaning the main passageway and spray gun. A check valve at the entrance to the main passageway prevents a backup of fluid components into the solvent supply system. The secondary passageway exits at the sides of the block to which are attached hose connecting fittings. The main passageway terminates in the opposite end of the block in threads for attachment to a main hose to a spray gun for spraying a fluid component such as paint. The exit end of the main passageway also provides a shoulder for an aligning sleeve for attachment of successive blocks in modular form to add additional valve connections for controlling the flow of additional fluid components. Each additional auxiliary block stacks end to end with the previous block with main passageways in each block being aligned by aligning sleeves. Studs of appropriate length are provided according to the number of auxiliary blocks stacked end to end to secure and clamp the blocks to the main manifold or block. Each successive auxiliary block provides control and delivery of two additional fluid components.

Abstract: A pumping system for delivering unstable fluids under pressure, comprising a pair of alternately operated single-acting pumps operated by a double-acting air motor. The air motor is controlled by a reversible spool valve and mechanically operated air pilot valves. The single-acting pumps deliver and contain relatively small quantities of the unstable fluid to a positive flow metering system for connection to an outlet to spray guns or other equipment using the fluid. The metering system includes a metering valve, a flow meter and a bypass valve for removing trapped air and presetting flow.

Abstract: An Automatic fluid component Shut Off System which automatically shuts off the flow of one component in a plural component system when the pressure in another component falls below a predetermined amount. The system is comprised of pneumatically operated sources of fluid components such as a catalyst and a resin which are mixed as they are sprayed on an article. The automatic shut off system is comprised of a pressure sensing valve which is connected to one of the components to provide a pressure control point and controls the supply of air to an air operated servo valve controlling the flow of the other fluid component. The pressure control point is established by adjusting an air pressure regulator connected in series with the pressure sensing valve.

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.
