Abstract
Abstract There is described an apparatus for forming traffic regulating indicia on road surfaces by applying tape material on a predetermined marking line trace. The apparatus consists of the combination of a service motor-van provided with steering means and driven by a first operator, and of a tape material applicator subassembly connected to and serviced by said motor-van and provided with its own steering means designed to be acted upon by a second operator, and with sight and collimation means designed for being collimated with said trace by said second operator which compensates for differences between the actual path of said motor-van and the marking line to be exactly provided.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
211 words
An apparatus for applying tape material along a predetermined path defined by a marking line as outlined by a predetermined marking trace, in combination, comprising a service unit comprising a motor-van and a subassembly including a tape applicator device, said tape applicator device being located ahead of said service unit, said service unit having first steering means adapted to be operated by a first operator for driving said unit at a given speed along a first path approximately concurrent with said marking line, said subassembly having second steering means adapted to be operated by a second operator; sight and collimating means operative for collimation with said predetermined marking trace, said second steering means and said sight and collimating means being interconnected to provide the positioning of said tape applicator device upon said marking line as said sight and collimating means are collimated with said predetermined marking trace; and means for permitting relative lateral displacement between said service unit and said interconnected subassembly so as to compensate for differences between the path actually followed by said service unit and that of said tape applicator device upon and along said marking trace, said means for permitting relative lateral movement including pushing means for pushing said tape applicator device ahead of said service unit.
Claim 2
Independent Claim
211 words
An apparatus for applying tape material along a predetermined path defined by a marking line as outlined by a predetermined marking trace, in combination, comprising a service unit comprising a motor-van and a subassembly including a tape applicator device, said tape applicator device being located ahead of said service unit, said service unit having first steering means adapted to be operated by a first operator for driving said unit at a given speed along a first path approximately concurrent with said marking line, said subassembly having second steering means adapted to be operated by a second operator; sight and collimating means operative for collimation with said predetermined marking trace, said second steering means and said sight and collimating means being interconnected to provide the positioning of said tape applicator device upon said marking line as said sight and collimating means are collimated with said predetermined marking trace; and means for permitting relative lateral displacement between said service unit and said interconnected subassembly so as to compensate for differences between the path actually followed by said service unit and that of said tape applicator device upon and along said marking trace, said means for permitting relative lateral movement including pushing means for pushing said tape applicator device ahead of said service unit.
Claim 3
Dependent Claim
30 words
The apparatus defined in claim 1, wherein said pushing means comprises a roller supported for idle rotation about a vertical axis and a transversely extending bumper abutting against said roller.
Claim 4
Dependent Claim
52 words
The apparatus as defined in claim 1, wherein said pushing means comprises a spaced pair of flexible pushing rods intermediate with and connected to said service unit and said device, the flexibility of said rods cooperating with said second steering means of permitting lateral displacement of said device relative to said unit.
Claim 5
Dependent Claim
24 words
The apparatus as defined in claim 3, wherein in said rods are disposed at opposite lateral sides of said unit and said device, respectively.
Claim 6
Dependent Claim
32 words
The apparatus as defined in claim 1; and further comprising tape-supplying means on said service unit, and guide means for guiding said tape from said service unit to said tape applicator device.
Claim 7
Independent Claim
213 words
An apparatus for applying tape material along a predetermined path defined by a marking line as outlined by a predetermined marking trace, in combination, comprising a service unit comprising a motor-van and a subassembly including a tape applicator device, said tape applicator device being located ahead of said service unit, said service unit having first steering means adapted to be operated by a first operator for driving said unit at a given speed along a first path approximately concurrent with said marking line, said subassembly having second steering means adapted to be operated by a second operator; sight and collimating means operative for collimation with said predetermined marking trace, said second steering means and said sight and collimating means being interconnected to provide the positioning of said tape applicator device upon said marking line as said sight and collimating means are collimated with said predetermined marking trace; means for permitting relative lateral displacement between said service unit and said interconnected subassembly so as to compensate for differences between the path actually followed by said service unit and that of said tape applicator device upon and along said marking trace; and tape supplying means on said service unit, and guide means for guiding said tape from said service unit to said tape applicator device.
Claim 8
Independent Claim
213 words
An apparatus for applying tape material along a predetermined path defined by a marking line as outlined by a predetermined marking trace, in combination, comprising a service unit comprising a motor-van and a subassembly including a tape applicator device, said tape applicator device being located ahead of said service unit, said service unit having first steering means adapted to be operated by a first operator for driving said unit at a given speed along a first path approximately concurrent with said marking line, said subassembly having second steering means adapted to be operated by a second operator; sight and collimating means operative for collimation with said predetermined marking trace, said second steering means and said sight and collimating means being interconnected to provide the positioning of said tape applicator device upon said marking line as said sight and collimating means are collimated with said predetermined marking trace; means for permitting relative lateral displacement between said service unit and said interconnected subassembly so as to compensate for differences between the path actually followed by said service unit and that of said tape applicator device upon and along said marking trace; and tape supplying means on said service unit, and guide means for guiding said tape from said service unit to said tape applicator device.
Claim 9
Dependent Claim
20 words
The apparatus as defined in claim 6, said guide means comprising a guide channel disposed upwardly of said service unit.
