ABSTRACT OF THE DISCLOSURE A caulking gun nozzle has an Outlet slot which is opposed by a spaced baflle blade that is carried by the nozzle and that replaces the conventional separate backing strips and deflects the sealant laterally. The slot is at an acute angle to the length of the blade and also at an acute angle to the axis of the nozzle, and a smoothing member is disposed to the side of the end of the slot that is farthest from the blade and is spaced from the blade a distance that at least initially determines the thickness of applied sealant. The depth to which the nozzle may be inserted is adjustable.
The present invention relates to nozzles for caulking guns. Nozzles according to the present invention are particularly well adapted to insert sealing joints of mastic or cementitious material in cracks or crevices or gaps between building modules.
In the past, it has been proposed to provide caulking gun nozzles which would inject a sealant material into the space to be filled by the sealant. Ordinarily, however, the space to be filled had to be backed. For example, if a joint to be sealed is a through joint, then it has been conventional to provide a separate backing strip. Alternately, joints can be closed by projections formed on and disposed between the members to be sealed, so that the joint is self-backed. However, such constructions enlarge the size of the joint and are expensive. It has also been proposed to insert the sealant without backing, but it is in this case diflicult to control the thickness and shape of the joint.
Briefly, the present invention solves the problems of the prior art by providing a backing member which is spaced from and opposed to the discharge opening of the caulking nozzle and which is carried by the caulking nozzle itself, so that the nozzle is in effect self-backing. A smoothing member is also provided on the nozzle so as accurately to determine the thickness of the sealant, at least as initially applied. The invention is also characterized by special arrangements and relationships of the parts as will be described hereinafter.
In the accompanying drawing:
FIGURE 1 is a side elevational View of a caulking gun nozzle according to the present invention; and
FIGURE 2 is a top plan view of the device of FIG. 1.
In the drawing, there is shown a caulking gun nozzle according to the present invention, comprising a hollow pipe 1 which along the left-hand portion of its length as seen in FIGS. 1 and 2 is of hollow cylindrical form, and which at its extreme left end has pipe threads 2 for attachment to a caulking gun (not shown). The pipe 1 is flattened toward the right of the figures of the drawing, and terminates at the right end in an exit opening for the ejected sealant. This exit opening is bounded along two of its sides by inclined edges 3 that are disposed at an acute angle, preferably between about 45 and about 80, to the axis of the nozzle. The greater the angle, the less will be the thickness of the deposited strip of sealant. The exit opening is thus in the form of an elongated slot.
Opposed to and in line with the exit opening is an elongated baffle blade 4 which is preferably perpendicular to the axis of the nozzle and is preferably disposed at an acute angle to edges 3. Blade 4 is secured at one end to pipe 1 adjacent to those ends of edges 3 which are the nearest to blade 4.
A smoothing member 5 is also carried by and secured to pipe 1, and is spaced from blade 4 a distance that predetermines at least the initial thickness to which the sealant will be deposited. Smoothing member 5 preferably has a concave surface that is opposed to and opens toward blade 4, for imparting a complementary convex surface to the applied sealant. Smoothing member 5 is disposed at the end of edges 3 opposite the point of attachment of blade 4. Considering the direction of sealant application to be downward in FIG. 1, smoothing member 5 is at the downstream front portion of the slot between edges 3, While the point of attachment of blade 4 is at the inner and upstream end of the slot. The blade and the member 5 thus define between them an exit gap for deposited material, and the inclined edges 3 face partially in the direction of this gap.
Means are provided for adjustably setting the depth to which the nozzle can be inserted in the joint to be sealed, in the form of a member 6 having a nonlinear slot therein, through which a clamping screw 7 passes which secures the member 6 to the side of pipe 1. By loosening the screw 7 and shifting the member 6, an abutment surface such as appears at the extreme bottom or the extreme right portion of the member 6, as seen in FIG. 1, can be set at any of a variety of desired distances to the right or left as seen in FIG. 1, thereby to ensure that the exit opening of the nozzle can penetrate the joint only to a thus-determinable depth.
It is of course obvious that the joints to be sealed must be at least as wide as the flattened end of the nozzle so as to permit insertion of the nozzle end in the joint. At the other extreme, however, it has been found that joints at least three times as wide as the width of the flattened end of the nozzle can be sealed by use of the present invention.
In operation, the discharge end of the nozzle is inserted in the joint to the desired and predeterminable depth, with the baffle blade 4 parallel to the intended direction of movement of the nozzle. Deformable sealant is forced through the nozzle under pressure, to the right as seen in the figures of the drawing, and emerges from the exit opening and is deflected by blade 4 upwardly and down wardly as seen in FIG. 2 and upwardly as seen in FIG. 1, into sealing contact with the edges of the joint that would be immediately above and below the structure at 3, 4 in FIG. 2 if they were shown.
The nozzle is then moved along the joint, leaving a solid and lengthening plug of sealant behind it. To cross a previously applied line of sealant, the previous line is cut away to permit the nozzle to pass through.
Although the present invention has been described and illustrated in connection with a preferred embodiment, it 'will be evident that modifications and variations may be resorted to without departing from the spirit of the invention, as those skilled in this art will readily understand. For example, blade 4 can take other forms than that shown. Also, blade 4 can be disposed at an acute angle to the axis of the nozzle, for caulking places that are hard to reach. These and other modifications and variations are considered to be within the purview and scope of the present invention as defined by the ap pended claims.
