Abstract
Abstract A liquid-applying apparatus for transferring a measured amount of liquid, such as liquid globule, from a body of such liquid stored in a receptacle to an object relatively remote from the receptacle. The apparatus finds particular usage on production lines where it is desired to apply a small amount of liquid substance to each product undergoing fabrication as it steps along the line. The receptacle is provided with an interior catch basin or reservoir for holding a measured amount of liquid obtained from that stored in the receptacle. A dauber or applicator reciprocably moves between the receptacle and the production line in timed relation to the advancement of the products making contact at one end of its motion with the liquid in the catch basin to pick up the liquid to be delivered and depositing at the other end of its motion the picked-up liquid on a product advancing along the production line. Provision is included for automatically raising and lowering the level of the liquid in the receptacle in synchronism with the transfer motion of the applicator and raising the liquid to fill the catch basin after each time the applicator leaves the receptacle and lowering the liquid level below the basin when the applicator returns to the receptacle for replenishment.

Total Claims: 15
Claim 1
Independent Claim
169 words
Liquid-applying apparatus comprising, in combination, a receptacle adapted to contain a body of liquid, a reservoir in the receptacle adapted to contain a measured amount of the same liquid therein, means for changing the liquid level in the receptacle from a level below that of the reservoir to a higher level capable of flowing liquid into the reservoir, an applicator for applying a liquid globule, means mounting the applicator for bodily translatable movement from inside the receptacle where it contacts the reservoir to pick up a globule of liquid therefrom to a position remote from the receptacle where it deposits the liquid globule on an object, and means for moving said applicator in timed relation with the liquid-level-changing means and causing the applicator to contact the liquid in the reservoir when the liquid level is below the same and to lift the applicator out of the reservoir with a liquid globule attached thereto before the liquid level in the receptacle is raised to the level for filling the reservoir.

Claim 3
Dependent Claim
55 words
The invention described in claim 1 characterized in that the means for bodily translating the applicator comprises a pair of arms pivotally connected to the applicator to form a parallelogram arrangement for swinging the applicator in an arc from the receptacle to the object upon which the liquid globule is to be deposited and returned.
Claim 4
Dependent Claim
158 words
A liquid applicator comprising, in combination, a receptacle adapted to contain a body of liquid, a reservoir in the receptacle for containing a measured amount of the same liquid in the receptacle, means for changing the level of the liquid contained within the receptacle between two different levels, the higher level being capable of introducing liquid into the reservoir whereas the lower level is incapable of so doing, a dipping member mounted for movement into and out of contact with the liquid introduced into the reservoir to pick up a quantity of liquid therefrom, and means for moving said dipping member in timed relation with the means for changing the liquid level in the receptacle and causing the member to contact the liquid in the reservoir when the liquid body is at said lower level and to withdraw the member from contact with the liquid in the reservoir before the liquid body is raised to said higher level.
Claim 5
Dependent Claim
158 words
A liquid applicator comprising, in combination, a receptacle adapted to contain a body of liquid, a reservoir in the receptacle for containing a measured amount of the same liquid in the receptacle, means for changing the level of the liquid contained within the receptacle between two different levels, the higher level being capable of introducing liquid into the reservoir whereas the lower level is incapable of so doing, a dipping member mounted for movement into and out of contact with the liquid introduced into the reservoir to pick up a quantity of liquid therefrom, and means for moving said dipping member in timed relation with the means for changing the liquid level in the receptacle and causing the member to contact the liquid in the reservoir when the liquid body is at said lower level and to withdraw the member from contact with the liquid in the reservoir before the liquid body is raised to said higher level.
Claim 6
Dependent Claim
80 words
The invention described in claim 3 characterized in that the reservoir is in the form of an opened top basin over the sidewalls of which the liquid in the receptacle flows to fill the same at the time the liquid body is raised to its higher level, and in that the dipping member is shaped at its lower extremity to abut the top edge of the basin in order to effect transfer of liquid from the reservoir to the member.
Claim 7
Dependent Claim
91 words
In a liquid applicator, a vessel for containing a body of liquid, a member mounted for movement and having a vertical component of motion within the vessel, means for alternating raising and lowering the member with respect to the vessel, and means for changing the level of a body of liquid in the vessel in timed relation with the raising and lowering of the member and operable to raise the liquid level within the vessel when the member is raised and to lower the liquid level when the member is lowered.
Claim 8
Dependent Claim
91 words
In a liquid applicator, a vessel for containing a body of liquid, a member mounted for movement and having a vertical component of motion within the vessel, means for alternating raising and lowering the member with respect to the vessel, and means for changing the level of a body of liquid in the vessel in timed relation with the raising and lowering of the member and operable to raise the liquid level within the vessel when the member is raised and to lower the liquid level when the member is lowered.
