Abstract
Abstract Apparatus for applying tape to a paved surface to form markings on the surface, said apparatus being supported for movement along the paved surface by wheel means including at least one roller, and further including tape support means for rotatably supporting a roll of tape; tape guide means positioned above a leading edge of the roller; tape advance means for advancing tape that extends from the roll of tape over the tape guide means into position for the roller to press the tape against the paved surface; and cutting means for cutting the tape while it extends under tension from the roller to the tape guide means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
232 words
Apparatus for applying tape to a paved surface to form markings on the surface, said apparatus comprising a frame supported for movement along the paved surface by wheel means including at least one roller, and mounted on the frame: tape support means for rotatably supporting a roll of tape; tape guide means positioned above a leading edge of said roller; a tape advance lever pivotable between an initial position near said tape guide means and an advance position near the leading edge of said roller; actuating means mounted at the rear of the apparatus for moving the tape advance lever from the initial position to the advance position; tape gripping means attached to the tape advance lever and including a portion through which tape passed over the tape guide means may be inserted, said gripping means being operable to grip the inserted tape during movement of the tape advance lever from the initial position to the advance position and thereby advance the tape toward the paved surface, to the effect that the free end of tape is advanced into contact with the paved surface in front of the roller, drags on the paved surface during forward movement of the apparatus, is engaged by the roller, and is pressed against the paved surface; and cutting means for cutting the tape while it extends under tension from the tape guide means to the roller.
Claim 2
Dependent Claim
232 words
Apparatus for applying tape to a paved surface to form markings on the surface, said apparatus comprising a frame supported for movement along the paved surface by wheel means including at least one roller, and mounted on the frame: tape support means for rotatably supporting a roll of tape; tape guide means positioned above a leading edge of said roller; a tape advance lever pivotable between an initial position near said tape guide means and an advance position near the leading edge of said roller; actuating means mounted at the rear of the apparatus for moving the tape advance lever from the initial position to the advance position; tape gripping means attached to the tape advance lever and including a portion through which tape passed over the tape guide means may be inserted, said gripping means being operable to grip the inserted tape during movement of the tape advance lever from the initial position to the advance position and thereby advance the tape toward the paved surface, to the effect that the free end of tape is advanced into contact with the paved surface in front of the roller, drags on the paved surface during forward movement of the apparatus, is engaged by the roller, and is pressed against the paved surface; and cutting means for cutting the tape while it extends under tension from the tape guide means to the roller.
Claim 3
Dependent Claim
111 words
Apparatus of claim 1 in which the tape gripping means comprises a first gripping plate, a second pivotable gripping plate biased toward the first gripping plate; and holding means holding the first and second gripping plates in spaced relationship when the tape advance lever is in the initial position; the space gripping plates defining a slot through which tape passed over the tape guide means may be inserted; the second gripping plate being released from the holding means at the beginning of movement of the tape advance lever from the initial position to the advance position to allow movement toward the first gripping plate to grip the inserted length of tape.
Claim 4
Dependent Claim
40 words
Apparatus of claim 2 in which the holding means comprises a post which the second gripping plate engages during movement of the tape advance lever to the initial position, which pushes said gripping plate away from the first gripping plate.
Claim 5
Dependent Claim
58 words
Apparatus of claim 1 in which the cutter means includes two arms mounted one on each of the two sides of the frame, a knife blade extending between the forward ends of the arms, and actuating means for pulling on the arms to draw the knife blade through the tape extending between the tape guide means and roller.
Claim 6
Dependent Claim
91 words
Apparatus of claim 4 in which the tape support means includes means for rotatably supporting two rolls of tape side-by-side, whereby tape may be unwound from each roll and drawn over the tape guide means to a leading edge of the roller, and the knife blade of the cutter means extends across both lengths of tape but may be tilted toward one of the lengths of tape prior to translation of the knife blade toward the tape so as to cut one length of tape prior to cutting the other length.
Claim 7
Dependent Claim
69 words
Apparatus of claim 5 in which each of the arms is connected to an actuating pedal and each pedal has a projection that engages a projection on the other pedal during movement of the first pedal, initial movement of the first pedal causing the stated tilting of the knife blade, and movement of both pedals after engagement of the projections causing translation of the knife blade against the tape.
Claim 8
Dependent Claim
205 words
Apparatus for applying tape to a paved surface to form markings on the surface, said apparatus comprising a frame supported for movement along the paved surface by wheel means including at least one roller, and mounted on the frame: tape support means for rotatably supporting at least two rolls of tape side-by-side; tape guide means positioned above a leading edge of the roller; tape advance means for advancing tape that extends from the rolls of tape over the tape guide means into position for the roller to press the tape against the paved surface; and cutting means for cutting the tape while it extends under tension from the tape guide means to the roller, the cutting means comprising two arms mounted one on each of the two sides of the frame, a knife blade extending between the forward ends of the arms and across the lengths of tape that extend from the tape guide means to the roller; and actuating means for pulling one of the arms ahead of the other, whereby the knife blade may be tilted toward one of the lengths of tape prior to movement through the lengths of tape so as to cut one length prior to cutting the other length.
Claim 9
Dependent Claim
205 words
Apparatus for applying tape to a paved surface to form markings on the surface, said apparatus comprising a frame supported for movement along the paved surface by wheel means including at least one roller, and mounted on the frame: tape support means for rotatably supporting at least two rolls of tape side-by-side; tape guide means positioned above a leading edge of the roller; tape advance means for advancing tape that extends from the rolls of tape over the tape guide means into position for the roller to press the tape against the paved surface; and cutting means for cutting the tape while it extends under tension from the tape guide means to the roller, the cutting means comprising two arms mounted one on each of the two sides of the frame, a knife blade extending between the forward ends of the arms and across the lengths of tape that extend from the tape guide means to the roller; and actuating means for pulling one of the arms ahead of the other, whereby the knife blade may be tilted toward one of the lengths of tape prior to movement through the lengths of tape so as to cut one length prior to cutting the other length.
Claim 10
Dependent Claim
94 words
Apparatus of claim 7 in which the cutting means includes two pedals, one being connected to each arm, and the pedals each have a member that extends into the path of movement of a member on the other pedal such that after a predetermined actuating movement of one pedal to cause the stated tilting of the knife blade, the second pedal is caused to move, thereby moving both arms together and drawing the knife blade through one length of tape and then by continued pressure on the pedals through the other length of tape.
