Description
- The present invention relates generally to a rotating nozzle assembly for dispensing flowable materials, such as caulk, sealant or other flowable materials from a dispensing device, such as a caulk gun.
- During the production of automotive vehicles, for example, a fabricator uses a dispensing gun to apply a bead of sealant to the vehicle frame prior to the installation of an automobile windshield. The bead is applied along a pinchweld in the frame defining the windshield periphery, and the windshield is positioned thereon. One edge of the windshield is applied to the adhesive bead in the pinch weld, and then the windshield is released and pressed into place. When using a conventional dispensing device to apply such a sealant bead, each time another corner of the windshield periphery is reached, it is necessary for the operator to reposition his body and/or the dispensing device to change the direction in which the bead of sealant is dispensed from the device. Such repositioning is time consuming and inconvenient to the operator. The present invention overcomes these drawbacks by providing a rotatable nozzle assembly in combination with a dispensing device. The direction from which the sealant bead is dispensed from the nozzle can be adjusted by simply rotating the nozzle assembly during dispensing, thus eliminating such inconvenient and time consuming repositioning of the operator's body and the dispensing device.

FIG. 6A is an enlarged exploded view of the second embodiment nozzle assembly of the present invention. - Referring now in detail to the various figures of the drawings wherein like reference characters refer to like parts, there is shown at 10 in
FIGS. 1-3 , a nozzle assembly for use in combination with a device for dispensing flowable materials such as caulking materials, grease, automotive windshield sealant, resins, and the like. Thenozzle assembly 10 is arranged to fit on the dispensing end of such a dispensing device, such as acaulking gun 14, which typically includes abarrel 18, only a small portion of which is shown inFIGS. 1 and 2 . In particular, thenozzle assembly 10 includes aconduit 22 having an externally threaded inlet end and an externally threaded outlet end. Thenozzle assembly 10 is arranged to attach to the dispensing end of thecaulking gun 14 by means of a screw-oncoupling 26. More specifically, thecoupling 26 includes awider end 26 a having internal threads (shown inFIG. 2 ) arranged for threaded engagement with thebarrel 18 and anarrower end 26 b, also having internal threads (shown inFIG. 2 ), arranged for threaded engagement with the inlet end of theconduit 22. Theconduit 22 can be formed of any suitable material, e.g., copper, and is shown in the figures as including two straight sections and an elbow or bend which turns at an angle of approximately ninety degrees. It should be understood that alternatively, theconduit 22 could be straight, or of any other configuration or include one or more bends as required by an operator to best suit the application. - A
head assembly 30 is shown mounted over theconduit 22 at the outlet end thereof. Thehead assembly 30 includes a thin-walled housing member 34 and acap member 38. Thecap member 38 is arranged for threaded engagement with thehousing member 34. Thehousing member 34 includes anopening 36 at its top end to enable passage of theconduit 22 therethrough. As best shown inFIG. 3 , the size of theopening 36 in thehousing member 34 is somewhat larger than the outside diameter of theconduit 22 passing therethrough. Thecap member 38 is also provided with an opening to enable passage of anozzle 46 therethrough. The opening in thecap 38 is sized to provide a snug fit with thenozzle 46 passing therethrough. The outside surface of thehousing member 34 is provided with aknurl 42 or other means for manually gripping thehousing member 34 to facilitate manual rotation of thehead assembly 30 during dispensing of flowable material from the dispensing device in ways to be described below. - Referring now to
FIGS. 2 and 3 , a generally cylindrical shapedfitting 54 is shown fitted within thehead assembly 30. Thefitting 54 is provided with an annular notch or slot for mounting an O-ring 58 thereon to assure a liquid seal exists between thefitting 54 and thehousing member 34. Thefitting 54 can be formed of any suitable material, e.g., rubber or plastic, and includes a centralaxial opening 54 a therethrough. As best shown inFIG. 2 , the upper portion of thecentral opening 54 a is internally threaded to enable threaded securement of the outlet end of theconduit 22 to thefitting 54. As best shown inFIG. 2 , theconduit 22 extends into thecentral opening 54 a only a portion of the distance therein, e.g., halfway. The lower portion of thecentral opening 54 a flares outwardly as it extends downwardly to match the diameter of the inlet end of thenozzle 46. - The
nozzle 46, extending through the opening of thecap member 38, comprises atapered wall 48 including a wider inlet end, a narrower outlet end, and askirt 50 at the inlet end which extends radially outwardly. As best shown inFIG. 2 , the diameter of theskirt 50 is approximately equal to the outer diameter of thehousing member 34 and is arranged to be seated within thecap member 38. Thenozzle 46 is fixedly secured to thehead assembly 30 due to theskirt 50 being sandwiched between thehousing member 34 and thecap member 38, which are shown in threaded engagement with each other. Thenozzle 46 may be formed of any suitable material, e.g., plastic or rubber. As best shown inFIGS. 1 and 3 , thetapered wall 48 of thenozzle 46 is provided with a triangular cut-outsection 60 which extends upwardly from the nozzle outlet end. During dispensing, flowable material will exit the outlet end of thenozzle 46 as well as the cut-outsection 60 in thetapered wall 48 to create a dispensed bead. - In use, upon actuation of the
dispensing device 14, flowable material will exit thebarrel 18 of thedevice 14 and flow through theconduit 22 and out thenozzle 48 through the outlet end including the cut-outsection 60. The cross-sectional shape of the dispensed bead will take on the shape of the cut-outsection 60 through which it passes, e.g., triangular. It is important to mention that although the cut-outsection 60 is illustrated inFIGS. 1 and 3 as being triangular, this shape is merely exemplary, and other shapes of the cut-outsection 60, e.g., round, are contemplated within the scope of this invention based upon the requirements of the application. Upon rotation of theknurl 42 of thehead assembly 30 during dispensing of flowable material, the cut-outsection 60 will rotate to any one of a plurality of positions to enable the dispensed bead to exit thenozzle assembly 10 in any direction. - For example, in an automotive application, it is required that a bead of sealant having a triangular cross-section be applied to a vehicle frame along a pinchweld in the frame defining the windshield periphery prior to the installation of an automobile windshield. When using a conventional dispensing device to apply such a shaped bead, each time another corner of the windshield periphery is reached, it is necessary for the operator to reposition his body and/or the dispensing device to change the direction in which the bead of sealant is dispensed. Such repositioning is time consuming and inconvenient to the operator. Under the present invention, during dispensing of the sealant bead, the operator grasps the
knurl 42 of thehead assembly 30. Each time another corner in the vehicle frame is reached requiring a change in direction, instead of the operator repositioning himself and/or the dispensing device, the operator merely rotates theknurl 42 to change the position of the cut-out 60, thus changing the direction from which the bead of sealant exits thenozzle assembly 10. As a windshield has four corners, as each new corner is reached on the vehicle frame, the operator merely rotates theknurl 42 approximately ninety degrees during dispensing to change the direction from which the bead of sealant exits thenozzle assembly 10. In this manner, the bead of sealant may be applied around the vehicle frame defining the windshield periphery thus eliminating the need for such repositioning with each new turn. - Referring now to
FIGS. 4-6 , and 6A, there is shown at 100 a second embodiment nozzle assembly for use in combination with a device for dispensing flowable materials such as caulking materials, grease, automotive windshield sealant, resins, and the like. Thenozzle assembly 100 is arranged to fit on the dispensing end of such a dispensing device, such as acaulking gun 114, which typically includes abarrel 118, only a small portion of which is shown inFIGS. 4 and 5 . As best shown inFIG. 5 , thenozzle assembly 100 includes aconduit 122 having an integral radially-extendingflange 126 located at an inlet end. Referring now toFIG. 5 , the radially-extendingflange 126 extends outwardly beyond the outside diameter of theconduit 122. At the opposite end (or outlet end) of theconduit 122, an outwardly facinggroove 130 including anintegral lip 134 is shown. Thelip 134 extends circumferentially about theconduit 122 and has an outer diameter that is no greater than the outer diameter of theconduit 122. Theconduit 122 can be formed of any suitable material, e.g., copper or plastic, and is shown in the figures as including an elbow or bend which turns at an angle of approximately ninety degrees. It should be understood that alternatively, theconduit 122 could be straight, or of any other configuration or include one or more bends as required by an operator to best suit the application. - Referring now to
FIGS. 5 and 6 , a generally ring-shapedfront cap 138 having a central opening is arranged to be slid over theconduit 122 from the outlet end toward the inlet end thereof. Thefront cap 138 includes an inwardly extendingflange 140 that comes into abutting relation withflange 126 of theconduit 122 as thecap 138 is slid towards the inlet end of theconduit 122. In this manner, thefront cap 138 is retained on theconduit 122 at the inlet end thereof. Thefront cap 138 includesinternal threads 138 a to facilitate threaded engagement with external threads located on the dispensing end of thedispensing device 114. Aknurl 138 b (best shown inFIGS. 4 and 6 ) is provided on the exterior surface of thefront cap 138 to facilitate secure attachment of the inlet end of theconduit 122 to the dispensing end of thedispensing device 114. - Once the
conduit 122 is secured to thedispensing device 114 using thefront cap 138, a generally ring-shapedadapter 142 having a central opening is arranged to be slid over and retained on theconduit 122. After theadapter 142 has been slid over theconduit 122, a pair ofclips 146 may be fitted in place on theconduit 122 at the outlet end thereof. Referring toFIGS. 5 and 6 , eachclip 146 is provided with aninterior groove 150 including alip 154. Thegroove 150 of eachclip 146 is arranged to receive thelip 134 of theconduit 122 and thegroove 130 of theconduit 122 is arranged to receive thelip 154 of eachclip 146. Referring now toFIG. 5 , once theclips 146 are fitted in place over theconduit 122 at the outlet end thereof, theadapter 142 may be slid down theconduit 122 towards the outlet end so theclips 146 are retained within a lower recess in theadapter 142. Once in place, theclips 146 are free to rotate about the outlet end of theconduit 122. - Referring now to
FIGS. 5 and 6 , an internally threadednozzle cap 158 includes a central opening that is arranged for passage of anozzle 162 therethrough. Thenozzle 162 is provided with atapered wall 164 and askirt 168 for retaining thenozzle 162 within thecap 158. As best shown inFIG. 5 , thecap 158 includes internal threads and is arranged for threaded engagement with the externally threadedadapter 142 to securely retain theskirt 168 andclips 146 between theadapter 142 and thecap 158. - The outside surface of the
adapter 142 is provided with aknurl 166 or other means for manually gripping theadapter 142. During dispensing of flowable material from the dispensing device, manual rotation of theadapter 142 causes rotation of theclips 146,nozzle 162 andcap 158 in unison about the outlet end of theconduit 122. As in the first embodiment, thetapered wall 164 of thenozzle 162 includes a wider inlet end, a narrower outlet end. Thenozzle 162 may be formed of any suitable material, e.g., plastic or rubber. - As best shown in
FIGS. 4 and 6 , thetapered wall 164 of thenozzle 162 is provided with a triangular cut-outsection 170 which extends upwardly from the nozzle outlet end. As described in the first embodiment, during dispensing, flowable material will exit the outlet end of thenozzle 162 as well as the cut-outsection 170 in thetapered wall 164 to create a dispensed bead. Upon rotation of theknurl 166 during dispensing of flowable material, the cut-outsection 170 will rotate to any one of a plurality of positions to enable the dispensed bead to exit thenozzle assembly 100 in any direction. As shown inFIG. 5 , theclips 146 are shaped to prevent leakage of dispensed material as it passes out theconduit 122 and across theflange 168 of thenozzle 162. - The devices of the present invention have been described in respect to the particular embodiments thereof set forth in the specification and as illustrated in the drawings. As a result of such disclosure, other variations and modifications may become apparent to those skilled in the art and therefore, no limitation as to the scope of the invention is intended by the specific embodiments disclosed but the scope of the invention is to be interpreted in view of the appended claims.
