Abstract: The invention teaches a kit-like system and apparatus for dispensing a multiple component reactive material from two cartridges each having an exteriorly threaded semi-cylindrical outlet nozzle, where the respective components need not be mixed together immediately, but only in close proximity of the intended use of the material. Thus, the cartridge nozzles will be spaced from one another, and at least one will be paired up with a dummy nozzle having a like exteriorly threaded semi-cylindrical nozzle, but with no outlet. Special universal fittings are provided in the kit that fit over the paired cartridge and dummy nozzles, and over a separate conventional mixer, and further that allow for hoses to be connected thereto, to define separate component flow paths from the separate cartridges to the remotely located mixer and then to the intended discharge location.

Abstract: A material handling fitting consisting of a tube having inlet and outlet ends, with the tube being stepped between its ends and having a plurality of respectively opposed outer and inner land areas of progressively smaller to larger diameters from one of its ends to the other. The different respective outer and inner land areas are sized to correspond to and telescopically cooperate selectively with inner and outer land areas respectively of substantially conventional material dispensing members, over a wide range of sizes and types. Upon two of such members being telescoped simultaneously with the opposite fitting ends, separable leakproof joints can be established for defining a continuous passageway between the dispensing members via the fitting, suited for conveying therethrough material under pressure.

Abstract: The disclosed port device has a tube with a base that can be permanently bonded to a surface with its outlet throughbore aligned with a crack therein, for funneling the material into the crack; and the port device tube can have a low silhouette of possibly 3/8" high overall, suited for leaving the device in place after crack filling had been completed. The material under pressure can be communicated to the port device via a flexible hose connected between special fittings, that respectively can be seated across leakproof joints established with the material dispensing system and with the port device. This means that the material dispensing system can be well spaced physically from the crack itself, by almost the hose length, and that the operator need not hold the material dispensing system relative to the crack.

Abstract: The disclosed port device has a tubular inlet end stepped with progressively smaller land areas sized to establish a leakproof separable joint with outer land areas of conventional material mixing/dispensing tubes. Separate radial base blades hinged from the port device near its outlet end fit either unfolded flush against a flat surface aligned over a crack therein or back-folded into the crack itself, for alternative uses of the port device. The port device beyond the base is beveled across end edges, for cooperating with corner surfaces and guiding material discharge under pressure into an underlying corner crack, where two partly folded base blades can then fit flush against the corner surfaces. An expandable sleeve fitted into the structure crack can be deformed radially upon tightening a nut for retaining the port device in the structure even when dispensing material under high pressures into the crack, as by an accessory fitting mechanically locked to the port device.

Abstract: A check valve disposed to fit between paired outlet nozzles of adjacent cartridges of a multiple component reactive fluid system and a mixing tube sealed over the nozzles and having a single outlet for discharging the mixed reactive material. The check valve has a flat portion and an upstanding wall formed therefrom, each sized and shaped to seat over the nozzles and against the mixing tube. Openings formed in the flat portion commumicate with the nozzles and provide separate flow paths of the respective materials to the mixing tube. Check structure as separate flaps integral with the wall cover and close the openings. The internal flap resilience normally holds the check valve closed, but allows flap flexture to open the outlet nozzle when the cartridge pressures exceed the closing forces. The check valve restricts back flow of either material into either outlet nozzle.

Abstract: The disclosed universal tool has a front plate with an open ended slot extended from near the front wall center, with the front wall defining the slot having one thickness and the wall spaced from the slot having a greater thickness. The front wall further can be mounted in the tool in two different arrangements, respectively flipped over 180 degrees. This tool thereby accommodates different paired material cartridges, both as to size to give different component ratios and as to constructions, such as from different manufactures. The cartridges further can be shifted along the slot as needed to remain parallel to the plunger rods that drive plungers through the cartridges to cause material discharge therefrom. The stable front wall-cartridge cooperation also holds the cartridge and easily allows rearward plunger withdrawl from the emptied cartridge.

Abstract: The surface port device has a tube with a throughbore between its inlet and outlet ends, and an enlarged flat base at the outlet end, suited to be bonded by adhesive securely to a structure surface with the tube bore aligned over a surface crack. The inlet tube end is stepped, having several adjacent generally cylindrical axially extended land areas of progressively smaller diameters I.D. in moving downstream toward the outlet end. The land areas are sized both in diameter and axial length to correspond to certain more common generally cylindrical land areas of conventional available material mixing/dispensing tubes proximate the outlet nozzles thereof. This allows the establishment of a mechanically sound leakproof separable joint between the material dispensing tube end the surface port device. A captive check ball in the tube bore automatically can be shifted between opening the port bore or closing it to preclude material backflow.

Abstract: A material dispensing tool has restraining and rear walls spaced apart to receive a material cartridge therebetween, and has an elongated rod supporting a plunger for movement between the walls and within the cartridge. A power ratchet mounted rearwardly of the rear wall over the elongated rod incrementally moves the elongated rod. Linkage including a spring concentrically arranged on the elongated rod effectively couples the power ratchet relative to the restraining wall, whereby the elongated rod can be resiliently biased by the strained spring. Output movement of the elongated rod relative to the power ratchet can thus be substantially independently of the plunger movement relative to the cartridge, the strained spring generating nearly uniform resilient plunger forces to discharge material from the cartridge.

Abstract: The disclosed tool dispenses material from a tubular cartridge having a front closure wall and nozzle, and having a wiper closing an open cartridge end and slidable forwardly within the cartridge. A plunger sized to fit within the cartridge is carried on a rod for moving the plunger axially within the cartridge against the wiper. The plunger has a conically ramped surface expanding from its smallest adjacent a front shoulder to its largest adjacent a rear shoulder, and rear and front peripherical guide surfaces extended endwardly from the radial shoulders to cooperate with the cartridge.

Abstract: The improved dispensing tool has linkage that includes a spring connected between a power ratchet and a wall restraining the material cartridge against plunger movement through the cartridge for discharging material, thereby allowing resilent independent plunger movement within the limits of spaced stops. When subjected to only static force conditions, the spring bottoms the linkage solid against one of the stops, to provide in-unison forward indexing of the plunger and ratchet drive rod. In the event plunger displacement occurs that is less than the expected in-unison indexing, the one linkage stop is gapped to subject the spring to additional dynamic force conditions that biases the plunger resiliently and continuously in the forward direction toward the restraining wall, up to maximum dynamic force conditions that bottoms the linkage solid against the other stop. The dynamic spring forces move the plunger forwardly within the cartridge for discharging the contained material.
