Applicator tip for dispensing liquid adhesive to seam adjacent layers of floorcovering sheeting

An applicator tip for seaming linearly abutting side-by-side layers of floorcovering with liquid sealant to form a seam extending along the line of abutment, comprising:

• an upright body having, from top to bottom, a leg portion, a relatively narrow ankle portion and a foot portion, said body having a leading edge and a trailing edge which are aligned with the line of abutment;
• said leg portion forming a passageway extending longitudinally therethrough and having means at its upper end for connection with a sealant supply container, whereby sealant may flow downwardly through said leg portion to said ankle portion;
• said foot portion having a bottom surface having a longitudinal center line aligned with the seam, said foot portion comprising first means for uplifting and tilting marginal portions of the floorcovering layers, to bring the floorcovering side edges close to the ankle portion side surfaces as the tip is advanced along the seam;
• said ankle portion having a longitudinal passageway communicating at its upper end with the leg passageway, said ankle portion forming ankle passageway outlet means for discharging sealant immediately above the central part of said foot portion first means, said body forming a laterally extending barrier immediately to the rear of said outlet means for directing sealant flow laterally as it issues from said outlet means, whereby the sealant is directed toward the adjacent upraised and tilted floorcovering side edge;
• and
• said ankle portion further comprising second means, extending out laterally from each side surface of said ankle portion in spaced relation above the sealant outlet and the top surface of said first means, for contacting said uplifted marginal portions to guide their side edges into close-fitting engagement with said ankle portion side surfaces.
