Description
~8729 BACKGROUND OF TilE INVENTION
-Caulking guns are well-known in the art and may be manually or power operated. Usually they are designed to dispense caulking compound from a pre-packaged cartridge by driving a piston through the cartridge to expel compound from a nozzle.
One power driven caulking gun disclosed in the art utilizes an electric hand drill as the power source. In that case, the device is secured to the device above and parallel with the drive shaft and is drivably coupled with the drill by a flexible cable being clamped at one end within the chuck o~ the drill and secured at the other end to gearing of the device.
Motion is transmitted to the gearing on rotation of the drive shaft through the flexible cable and is translated into longitudinal motion of a piston to dispense caulking compound from a nozzle through speed reduction gearing and a sophisticated drive train.
SUMMARY OF T~E INVENTION
I-t is an object of the invention to provide a very simple reliable caulking gun possibly using an electric drill as a power source.
It is another object of the invention to provide a caulking gun which may be manufactured by modifying the production of electric drills.
It is an alternate object of the invention to provide a caulking gun accessory for an electric drill.
Accordingly, the invention provides a caulking hand gun comprising a power source located in a housing and having a variable speed reversible direction drive shaft, and control means to control -the speed of the drive shaft; and caulking means comprising a cylinder for receiving caulking compound abutting said housing at one end and ~187'~9 securable thereagainst, said cylinder having a dispensing nozzle at the other end, a pis-ton within said cylinder having a telescopically extensible piston rod of at least three sections, one end section of which being secured to said drive shaft and the other end section being attached to said piston, the sections being in screw threaded engagement one with another to be successively telescopically extensible on operation of said drive, whereby on extension of said piston rod by means of operation of said drive, said piston acts to dispense caulking compound from said nozzle.
IN THE DRAWINGS
Figure 1 illustrates a side view of one embodiment of the invention with the side wall of the cylinder cut away to show the interior.
Figure 2 is a section on the line A-A of Figure 1 with the side wall of the cylinder complete.
Figure 3 is a view similar to that of Figure 1 but showing an alternate embodiment.
Figure 4 is a side view of one telescopic piston rod showing screw threaded connections between sections.
In the drawings, an elPctric power source in a housing 1 fed by a cable 2 is provided with drive shaft 3 having variable speed and reversible direction controlled ~5 through control switch 4. The arrangement of the power source in housing 1, drive shaft 3, and control switch 4 may conveniently be that of a conventional electric hand drill, either adapted in manufacture for the addition of a caul.king cylinder 22 or provided with means to attach caulking 7:;~9 cylinder 22 as an accessory for the electric drill. The caulking cylinder 22 is secured to the housing 1 by any convenient means and may, when the caulking cylinder is an accessory, be releasable from the housing 1 leaving the assembly of the power source in the housing 1, with cable 2, drive shaft 3 and control switch 4 operable independently as an electric drill. The caulking cylinder 22 may be such as to accept caulking compound from a bulk source (see Figure 1) or to accept a pre-packaged cartridge 5 of caulking compound (see Figure 3).
When the cylinder 22 is to accept bulk caulking compound any conventional access means (not shown) may be provided for filling and re-filling the cylinder. If the cylinder wall is continuous and the cylinder is sealed, caulk can be introduced thereinto by suctioll through the nozzle.
The cylinder 22 is provided with a nozzle 6 to dispense caulking compound. The nozzle 6 is located on a cap 7 which may be removable from cylinder 22 so that different types of nozzle 6 can be interchanged into the device.
Inside cylinder 22 is piston 8 located at one end of telescopic piston rod 9, the other end of which is secured to the drive shaft 3.
As shown in Figure 1, the drive shaft 3 is directly connected to piston rod section 10 but such connection, especially when the caulking arrangement is an accessory for an electric hand drill, may be through a drill chuck 11 (Figure 3).
The piston rod 9 comprises hollow section 10 fixed at one end to drive shaft 3 to rotate wlth it and extending ,r axially within cylinder 22. Section 10 is provided with internal screw threading 12 at its other end, the screw threads 12 engaging with screw threads 13 extending over the length of an intermediate section 14 of piston rod 9.
Section 14 is a hollow section oE smaller radius than section 10 so that it can nest within it. Rotation of the sections 10, 14 relative to each other causes, through the screw threads 12, 13 retraction of section 14 into, or extension of section 14 from, section 10. Section 14 is provided with a stop 15 to prevent removal from section 10.
Similarly to section 10, section 14 has internal screw threading 16 at its end distant from drive shaft 3.
The screw threading 16 engages with screw threading 17 extending over the length of section 18 of piston rod 9.
Section 18 is a rod carrying piston 8 at one end and having a stop 19 at the other end to prevent complete removal from section 14. Relative rotation between sections 14 and 19 causes retraction or extension of section 19 from section 14.
At least when a source of bulk caulking compound is to be used, piston 8 is provided with means to prevent its rotation in cylinder 22. When cylinder 22 is for bulk caulking compound (see Figures 1 and 2) the means to prevent rotation may be a guide tip 20 running longitudinally internally on cylinder 22 cooperating with a slot 21 in the : periphery of piston 8. Alternatively, a lug on the piston periphery may run in a groove of the cylinder 22.
Caulking compound from a bulk supply can be introduced into the cylinder 22 by suction through the nozzle 6 by operation of the piston 8 in the reverse manner to that for the extrusion of caulking compound.
When the cylinder is for a cartridge of packed caulking compound, it may be that friction between the 1:118729 cartridge and the piston is sufficient to prevent the piston turning. However, it may be advantageous to provide the piston with a lug whereby it will forge a groove in the cartridge material and act as an added restraint against the piston turning.
To make the device ready to operate, the sections 14 and 18 are retracted fully :into their nesting positions.
The cylinder 22 is filled with caulking compound or provided with a caulking cartridge. The device is then ready to operate.
, To operate the device, the drive shaft is rotated forwardly at the desired speed by operation of control switch 4. Section 10 of piston rod 9 rotates with drive shaft 3 and, since there are no restraints on section 14 at this time, section 14 tends to rotate with it. Section 18 is restrained from rotation by the restraining means acting on piston 8 and hence there is relative rotation between section 18 and section 14. Due to the unscrewing action between screw threads 16 and 17 section 18 starts moving ~0 longitudinally out of section 14. Piston 8 acts on caulking compound to dispense it through nozzle 6. When stop 19 abuts screw threads 16 no further unscrewing is possible between sections 18 and 14 so section 14 becomes locked with section 18 against rotation. At this point relative rotation ; 25 between sections 10 and 14 begins and section 14 starts moving longitudinally out of section 10 thus further actuating piston 8. Finally, stop 15 abuts screw threads 12 and no further extension is possible. A suitable total extension is 8 inches. To prevent damage to the power source at this point it is convenient to provide a warning signal just before the final stop point is reached. Alternatively, an automatic clutch can be provided. At, or just before the ~`
final stop point, tlle clirecti !l of the drive shaft shoulcl be reversed to re-nest the sec~ s 10, 14 and 18 so the cylinder may be resuppliecl with caulking compound.
The telescopic arran~ement of piston rod 9 has various advantages in that the total length of the device is controlable. ~ore than three sections can be used if desired. Moreover, if an ordinary hand drill is used the control button may be adapted to have a longer than normal travel so that the speed is more easily controllable.
Although the device has been described for use with caulking compound it may be used for other materials, e.g.
grease.
