Applicating devices

Claim 2

An applicating device comprising an encasement; a drive source mounted to said encasement; a storage chamber, secured to said encasement, enclosing a disposable cylindrical cartridge, containing a high viscosity fluid for application, having a dispensing opening at one end and a removable cap at the other end; a means of changing angular motion to linear motion consisting of a modified rack gear which travels linearly through said encasement and said storage chamber forcing said high viscosity fluid out said dispensing opening; a spur gear which drives said modified rack gear; a gear train structurally supported in said encasement with gear means to perpendicularly couple and reduce the angular motion of said drive source to the angular motion of said spur gear; and a dividing plate in said encasement for isolating lubricated high speed gears in said gear train from nonlubricated low speed gears in said gear train.

Claim 3

An applicating device as set forth in claim 1, wherein said gear means consists of a worm gear coupled to said drive source and axially fixed in said encasement; a wheel gear driven by said worm gear, secured to an axle which is axially supported in said encasement, facilitating a perpendicular coupling and reduction of angular motion of said drive source to the angular motion of said spur gear which is mounted on said axle.

Claim 4

An applicating device as set forth in claim 1, in which said modified rack gear is comprised of a round bodied rod having a set of mating teeth corresponding to the teeth of said spur gear; a flat which is the full length of said modified rack gear perpendicular to and at the same depth as the roots of said set of mating in said modified rack gear; a set of annular teeth whose roots are tangent to said roots of said set of mating teeth and tangent to said flat and whose faces are contiguous to the faces of said set of mating teeth and whose crests are contiguous to the crests of said set of mating teeth; a handle at the end of said modified rack gear which is a short end piece of said modified rack gear bent at an anglE to facilitate angular turning of said modified rack gear and subsequent disengagement of said modified rack gear from said spur gear; a disk fixed to said modified rack gear at the end opposite of said handle adapted to force said high viscosity fluid out said dispensing opening of said storage chamber upon actuation of said modified rack gear by said drive source through said gear train; an automatic stop on said modified rack gear, at the opposite end of said disk, which is a number of said set of mating and said set of annular teeth that have been removed to the depth of said roots of said set of mating teeth and said roots of said set of annular teeth and would engage the teeth of said modified rack gear; and a keeper mounted to said encasement for biasing said modified rack gear to engage with said spur gear.

Claim 5

An applicating device as set forth in claim 1 wherein said modified rack gear is comprised of a rod, having a set of mating teeth corresponding to the teeth of said spur gear; an automatic stop at both ends of said modified rack gear which is a number of said set of mating teeth that have been removed to the depth of the roots of said set of mating teeth and would engage the teeth of said spur gear at that section of said modified rack gear; and a disk fixed to the end of said modified rack gear adapted to force said high viscosity fluid out said dispensing opening of said storage chamber upon actuation of said modified rack gear by said drive source through said gear train.

Claim 6

An applicating device as set forth in claim 1, wherein said drive source is detachably mounted to said encasement.

Claim 7

An applicating device as set forth in claim 5, wherein said drive source is detachably mounted to said encasement with a securing bar bent at a 90* angle with a slot in which it is adjusted and fixed to said encasement; and a securing clamp with which said bar is secured to said drive source.

Claim 8

An applicating device comprising an encasement; a drive source mounted to said encasement; a cylindrical storage chamber, containing a high viscosity fluid for application, secured at one end to said encasement, and having a removable cap with dispensing opening at the other end; a means of changing angular motion to linear motion consisting of a modified rack gear which travels linearly through said encasement and said storage chamber forcing said high viscosity fluid out said dispensing opening; a spur gear which drives said modified rack gear; a gear train structurally supported in said encasement with gear means to perpendicularly couple and reduce the angular motion of said drive source to the angular motion of said spur gear; and a dividing plate in said encasement for isolating lubricated high speed gears in said gear train from nonlubricated low speed gears in said gear train.

Claim 9

An applicating device comprising an encasement; a drive source mounted to said encasement; a cylindrical storage chamber, containing a high viscosity fluid for application, secured at one end to said encasement, and having a removable cap with dispensing opening at the other end; a means of changing angular motion to linear motion consisting of a modified rack gear which travels linearly through said encasement and said storage chamber forcing said high viscosity fluid out said dispensing opening; a spur gear which drives said modified rack gear; a gear train structurally supported in said encasement with gear means to perpendicularly couple and reduce the angular motion of said drive source to the angular motion of said spur gear; and a dividing plate in said encasement for isolating lubricated high speed gears in said gear train from nonlubricated low speed gears in said gear train.

Claim 10

An applicating device as set forth in claim 7 wherein said gear means consists of a worm gear coupled to said drive source and axially fixed in said encasement; a wheel gear driven by said worm gear, secured to an axle which is axially supported in said encasement, facilitating a perpendicular coupling and reduction of angular motion of said drive source to the angular motion of said spur gear which is mounted on said axle.

Claim 11

An applicating device as set forth in claim 7 in which said modified rack gear is comprised of a round bodied rod having a set of mating teeth corresponding to the teeth of said spur gear; a flat which is the full length of said modified rack gear perpendicular to and at the same depth as the roots of said set of mating teeth in said modified rack gear; a set of annular teeth whose roots are tangent to said roots of said set of mating teeth and tangent to said flat and whose faces are contiguous to the faces of said set of mating teeth and whose crests are contiguous to the crests of said set of mating teeth; a handle at the end of said modified rack gear which is a short end piece of said modified rack gear bent at an anglE to facilitate angular turning of said modified rack gear and subsequent disengagement of said modified rack gear from said spur gear; a disk fixed to said modified rack gear at the end opposite said handle adapted to force said high viscosity fluid out said dispensing opening of said storage chamber upon actuation of said modified rack gear by said drive source through said gear train; an automatic stop on said modified rack gear, at the opposite end of said disk, which is a number of said set of mating teeth and said set of annular teeth that have been removed to the depth of said roots of said set of mating teeth and said roots of said set of annular teeth and would engage the teeth of said spur gear at that section of said modified rack gear; and a keeper mounted to said encasement for biasing said modified rack gear to engage with said spur gear.

Claim 12

An applicating device as set forth in claim 7 wherein said modified rack gear is comprised of a rod, having a set of mating teeth corresponding to the teeth of said spur gear; an automatic stop at both ends of said modified rack gear which is a number of said set of mating teeth that have been removed to the depth of the roots of said set of mating teeth and would engage the teeth of said spur gear at that section of said modified rack gear; and a disk fixed to the end of said modified rack gear adapted to force said high viscosity fluid out said dispensing opening of said storage chamber upon actuation of said modified rack gear by said drive source through said gear train.
