Abstract
The sealant applicator hereinafter described in detail has been designed and constructed in such manner that, when operated to apply a ribbon or bead of sealant material to an article, piece of furniture or other work in which a sealed waterproof joint between or in structural members is required, the applied ribbon or bead is uniform in cross section throughout its entire length instead of varying in cross section as do the ribbons of sealant delivered by applicators of the types heretofore employed. To realize this objective a novel mechanism is employed, extrusion of sealant being effected at a rate which is strictly proportional to the linear progress of the spout which delivers the sealant carried in the sealant containing cartridge into the crack or joint to be sealed. Liquid under pressure, automatically metered, is utilized to effect the discharge of sealant.

9 Claims, 6 Drawing Figures CAULKING GUN The sealant applicator disclosed in the accompanying drawings is primarily designed to be manually operated and to effect the extrusion of sealant material from cartridges of the type now and heretofore commonly used and readily available. The invention, however, may be incorporated in machines of various types in which the work moves relatively to the applicator, or vice versa, and its details may be varied in order to most conveniently accomplish its primary objectives.
That embodiment of the invention which is illustrated by way of example is of such character that it may be easily operated by hand.
FIG. I of the drawings illustrates the applicator in top plan view.
FIG. 2 is a vertical longitudinal axial section. FIG. 3 is a partial longitudinal axial section showing certain of the operating parts in positions differing from the positions in which they appear in FIG. 2.
FIG. 4 is an end view of the applicator.
FIGS. 5 and 6 are sectional views taken on lines 5-5 and 6--6, respectively, of FIG. 1, showing details of construction.
The sealant applicator selected for disclosure by way of example comprises two main portions relatively movable along a common axis, such relative movement bringing about the discharge of sealant at a rate which is proportional to the rate at which the discharge spout of the sealant cartridge is advanced with reference to the work piece upon which the sealant is discharged, thus insuring a delivered ribbon of uniform cross section.
A sealant cartridge with displaceable bottom is indicated at S in FIGS. 2 and 3, the delivery spout thereof at P, FIG. 3, and a ribbon of delivered sealant at R, in FIG. 3. The cartridge S is contained within the end of a cylinder 10 of slightly larger diameter by means of a nearly circular clip 11 which is inserted in a circular groove formed in the annular member 12a fixed upon the end cylinder 10 and which is grasped by the hand to advance the cylinder and cartridge relatively to the work. Clip 1 1 is removed when the cartridge has been emptied of its content and a fresh cartridge inserted, the clip being then reinserted and comprising an abutment preventing movement of the cartridge when pressure is applied to its opposite end, that is, to its bottom to force the bottom toward the discharge end in customary manner.
The opposite end of the cylinder 10 is closed, except for a central aperture, by an annular member 12 and, slideably supported and confined within this cylinder is a piston 13 provided with a packing ring 14 to prevent passage of liquid thereby, members 12 and 13 defining between them an expansible and contractable chamber C for fluid, preferably a liquid of non-combustible character. Associated with piston 13 is a work member or push rod 15 to which is secured a disc 16 which is provided to apply pressure evenly over the moveable base of the cartridge to eject its content.
Secured within the central aperture formed in annular member 12 is the end of a tube 17 through which liquid may be introduced into the chamber C, and later withdrawn, this tube being coaxial with tube 10 and having secured to its opposite end a piston 18. The cartridge containing tube 10 is slideably housed within a tube 20 of slightly greater diameter and which comprises portion of a casing which is grasped by one hand of the operator when the device is being used, the operators other hand grasping the member 12a. The remainder of the casing comprises disc-like members 21 and 22 secured together by cap screws or other suitable means and a cylindrical part 24 one end of which is firmly attached to disc 22 and the opposite end of which is closed by an annular member or head 25. The operator, by grasping either tube 20 or casing 24 with one hand and member 12a with the other may readily move them axially relatively to each other. In the normal operation of the device the cartridge containing tube 10 will be advanced (as indicated by the arrow in FIG. 3).
while the structure which includes tube 20 and casing 24 will be prevented from moving, in certain of its uses being mounted upon a fixed support such as that diagrammatically illustrated at 26 in FIG. 2.
Piston 18, FIG. 2, secured to the end of tube 17, has liquid tight sliding engagement with the inner surface of cylinder 28, one end of which is mounted in a cylindrical aperture formed axially in member 22. Liquid passages 29 (FIG. 5) formed in tube 17 adjacent piston 18 permit the passage of liquid from the annular space intermediate tubular members 17 and 28 into tube 17, and vice versa, in the operation of the device. Liquid is stored in a reservoir of annular cross section defined by the outer surface of tubular member 28 and the generally cylindrical member 30 of rubber or other suitable flexible and elastic material the ends of which are intumed and clamped tightly against the inwardly facing surfaces of members 22 and 25, respectively, by annular clamping members 31 and 32, respectively, as shown in FIGS. 5 and 6.
The interior of the liquid storage reservoir is in communication with the annular space between tube 17 and cylinder 28 through valve controlled passages formed in members 21, 22 and 31, as most clearly shown in FIG. 6. Flow through passage 34 is controlled by a valve 35 normally held in closed position by a spring 36 and moved to open position by pressure applied to the lever 37, pivotally mounted at 38, the spring 36, confined between valve 35 and abutment 39, being compressed when the lever is pressed in the direction indicated by the arrow in FIG. 6 and restoring the valve to closed position when this pressure is removed. Flow of liquid through passage 40 is controlled, in one direction, by check valve 41. The annular space between piston 17 and member 28 is in constant communication with cross passage 42 formed in member 21.
It will be seen that liquid in this space and passages 40 and 42 may not escape into the reservoir when cylinder 10 and attached piston 18 are moved to the left (FIG. 2), valves 35 and 41 preventing such movement. Instead the trapped liquid will flow through ports 29 into tube 17 and be delivered to chamber C to move piston 13 and push rod 15 to the left (FIG 2). The amount of liquid delivered depends upon the length of travel of piston 18 and this piston travels a distance exactly equal to the travel of the cylinder 10 and the sealant cartridge housed in that cylinder. Therefore, the piston 13 and push rod 15 move, on their working strokes, adistance which always bears a constant relationship to the movement of the cartridge along the work, thus assuring that the same amount of sealant will be delivered per unit of travel.
A continuous bead of uniform cross-section will have been deposited during movement of piston 18 longitudinally of cylinder 28 for the full length of that cylinder and, to effect prolongation of the sealant bead the member 12a, and the cartridge, are maintained in fixed position while members 20, 24 and associated parts are moved toward the left (FIG. 3), piston 18 remaining relatively stationary, and thus there is obtained the necessary suction stroke by which the annular space between cylinder 28 and tubular member 17 is again filled with liquid drawn from the reservoir through the check valve 41 and passages 40 and 42. The cycle of operations is thus completed and when the bead to be deposited is relatively long and narrow, a larger volume of liquid than that indicated by the drawing may be necessary to enable the entire content of a sealant cartridge to be discharged. When the content of a cartridge has been completely discharged, the major portion of the fluid employed to advance piston 13 may be returned to the reservoir by holding open the valve 35 while a new and full cartridge is being inserted in tube 10, thereby forcing the piston 13 to return to its initial position, thereby pumping the liquid into the reservoir.
It will be apparent that the applicator may be employed to deliver sealant in ribbons of varying but uniform cross section by relatively moving its two major elements in different ways. Thus, if the sealant nozzle P is held against movement and the reservoir continuing portion is moved in a direction away from the nozzle the sealant will be discharged at one point to form a heap, which is sometimes desired. Ribbons of uniform cross section but of different dimensions may be deposited by simultaneously advancing the nozzle and moving the metering pump section simultaneously in the opposite direction, thusthe cross section of the head or ribbon. Thus the applicator may be employed to accomplish widely different tasks, as will be apparent.
spout may be angularly adjusted about the longitudinal axis of the applicator in the deposition of sealant upon work pieces which are not horizontally disposed. If desired, however, in adapting the applicator to the deposition of sealant along a fixed line, such rotation of the tube within the tubular member 20 may be prevented by providing the inner tube 10 with an outwardly projecting pin which is received within a longitudinally extending slot formed in the outer tube 20, or by some other means which performs the same function.
