Permanently installed power drive sources could also be adapted to the applicating device. Most applicating devices, such as caulking guns, grease gums etc., are manually operated and tend to fatigue the operator. The application of substances in slow, and the appearance of the resulting bead of the substance, which the applicating device produces, is often unattractive because of the irregularities produced by the hand operated'applicating device.
The object of this invention is to provide an applicating device which uses a disposable cartridge or a refillable chamber as a means of storing the substance to be applied.
Another object is to use a removable power source such as a portable electric drill or other such removable power supply; with slight modifications, a permanent source could be used with the applicating device.
The third objectis to improve the speed at which a substance can be applied. 1
A fourth object is to improve the physical comfort for the operator of this device.
Still another object is to improve the appearance of the resultant bead in cases such as caulking, where appearance is important.
The embodiment of this invention, together with the modifications, are illustrated in the accompanying drawings.
FIG. 1 is a perspective view of one form of the invention, showing a chamber for use with cartridges.
FIG. 2 is a plane view of one half of the encasement, showing the inside structural supports of the gears, and also showing a WOITI'I gear with retainer ring, wheel gear and axle.
FIG. 3 is a sectional view of both halves of the encasement, showing the structural supports of the gears, the relationship of the gears to each other and to the encasement, and the dividing plate and its position in the encasement.
FIG. 4 is a plane view of the other half of the encasement, showing the structural supports, axle, and the spur gear engaged in the modified rack gear.
FIG. 5 is a front view of the dividing plate.
FIG. 6 is a side view of the dividing plate.
FIG. 7 is a sectional view of the modified rack gear in the engaged position, and a front view of the locking bar, which is in the up" position; this allows the rack gear to be pulled out.
FIG. 8 is a sectional view of the modified rack gear in the engaged position, and a front view of the locking bar, which is in the down" position; this prevents the rack gear and the spur gear from disengaging.
FIG. 9 is a front view showing the modified rack gear disengaged from the spur gear.
FIG. 10 is a front view showing the modified rack gear and the spur gear at the automatic stop" position.
FIG. 11 is a perspective view of a refillable chamber, and chamber cap and spout assembly.
FIG. 12 is a perspective view of a rod rack gear.
FIG. 13 is a sectional view of the modified rack gear in the disengaged position, and a front view of the spring lock, which is in the disengaged position; this allows the rack gear to be pulled out.
FIG. 14 is a sectional view of the modified rack gear in the engaged position, and a front view of the spring lock, which is in the engaged position; this prevents the rack gear and the spur gear from disengaging.
With more detailed reference to the drawing, wherein like reference characters denote corresponding parts, the numerals 1 and 2 designate the encasement which can be produced by die casting or other such process from a strong material such as zinc or aluminum alloy. The modified rack gear 13, and the rod rack gear 21, the worm gear 6. the axle 22, the wheel gear 17, and the spur gear I6are made from a strong material such as steel, and may be produced by machining or other process. The locking bar 4, securing bar 5. and rack disk 15 may be made out of-a material such as steel, and may be produced by a process such as stamping. The cartridge chamber 8, the chamber 20, and the chamber cap and spout assembly 19 may also be made from a material such as steel and may also be produced by a process such as stamping, and a fastening process such as spot welding. The dividing plate 18 may be produced by a process such as stamping or die casting, and may be made from a material such as steel, zinc, or aluminum alloy. The retainer ring 14 may be made from a material such as steel, and be produced by a process suchas stamping. The hose clamp 7 may be made out of a material such as steel, and may be produced by a process such as machining and stamping. The spring lock 23 may be made out of such a material as spring steel.
In order to ready the applicating device such as in FIG. 1, loosen screws on securing bar 5, and loosen hose clamp 7. Place worm gear 6 in chuck of a portable electric drill and tighten chuck. Place securing bar 5 down on top of the drill body. Place the hose clamp 7 around both the body of the drill and securing bar 5. Tighten the hose clamp 7 and then tighten the screws on securing bar 5. Lift up the locking bar 4; this is not necessary if spring lock 23 is used, because it is self adjusting; turn handle 3 of rack gear 13 clockwise until it stops, then pull out rack gear 13 until it stops. Place a new cartridge of substance into cartridge chamber 8; turn handle 3 counterclockwise until it stops. Locking bar 4 will automatically fall in the down position thus securing the'modified rack gear 13 in the engaged position; if spring lock 23 is used instead of locking bar 4, it will also automatically secure the modified rack gear 13in the engaged position. Press the trigger of the drill, which will activate rack gear 13, thus causing the substance in the cartridge to flow. Release the trigger of the drill and the flow of the substance from the cartridge will stop. When rack disk 15 reaches the bottom of the cartridge, the
automatic stop 9 prevents the rack gear'l3 from traveling further and doing damage to the device. When the cartridge is empty, locking bar 4 is lifted to the up" position; if spring lock 23 is used, this is not necessary because it is self adjusting. Tum handle 3 clockwise until it stops; the rack gear 13 is pulled out until it stops. The empty cartridge is lifted out of the chamber 8, and a new cartridge is inserted ready for use.
When the refillable chamber 20, and chamber cap and spout assembly 19 is used, a cartridge is not necessary. This method of operation is similar to the method previously explained except that in order to fill chamber 20,.chamber cap and spout assembly 19 is removed and the open end of the chamber 20 is inserted into a container of substance. When rack gear 13 is pulled out, it causes the substance to flow into the chamber 20, thus filling it. When the chamber cap and spout assembly 19 is attached to chamber 20, the device is ready for operation.
When a drill with a forward and reverse direction is used with this device, the rod rack gear 21 can be used. Rod rack gear 21 has no handle 3, annular teeth 12, locking bar 4, or flat 11. It does not have to be circular in shape, but can be square or any other shape, so long as the rest of the device is adapted to it. It does not need to turn during any part of the operation; it only goes in and out of the chamber. It does require an additional automatic stop 9 near the rack plate 15 to prevent the plate 15 from causing damage when the drill is in the reverse position. The operation of the device is similar to the two previous operations except that the manual pulling out of the rack 13 is eliminated.
When the locking spring 23 is used instead of the locking bar 4, the necessity of lifting the locking bar 4 is eliminated due to the locking bar's automatically adjusting to the position of the rod rack 21.
While the invention has been described and illustrated in some detail on the forms shown, it is to be understood that changes may be made in minor details of the construction, without departing from the spirit of the appended claims.
