Abstract
Abstract An applicator machine for applying bitumen, adhesive, varnishes or highly viscous materials to a surface or roof comprises a wheeled frame having a storage tank for the flowable material and a transversely extending application means for applying the material to the surface. The wheels may be coated with silicone rubber to prevent adhesion of the applied material to the wheels. The application means includes a transversely extending distribution channel which is formed by a pair of rubber apron side walls defining an open slot at the lower ends thereof through which the material flows to the roof surface. To assure flow of material into the uphill section of the distribution channel when the machine is on a sloped roof, a valve means may be operated to direct the flow of material section of the channel means. Also, to assist working on sloped roofs, the application chamber may be pivoted in relationship to the tank.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
203 words
An applicator machine for a flowable material comprising a frame having wheels for movement in a given direction, a storage tank carried by said frame for carrying said flowable material to be applied to a surface over which the machine passes, application means for applying the flowable material to the surface and including a transversely extending chamber and a distribution channel therein, said chamber being open on the bottom to permit the material to flow downwardly through the open bottom of the chamber to the surface, flexible aprons extending downwardly from said bottom to define front and rear side walls for said chamber, conduit means extending between said storage tank and said application means to allow the material to flow therethrough and into the distribution channel, valve means for controlling the amount of material flowing to said distribution channel, means for deflecting the discharge of the flowable material from said conduit means in predetermined directions as toward the uphill side of the channel means when the machine is on a sloped surface, and manually adjustable means for controlling said deflecting means and movable to reverse the direction of material deflection when said machine has been turned about to travel in the reverse direction.
Claim 2
Dependent Claim
203 words
An applicator machine for a flowable material comprising a frame having wheels for movement in a given direction, a storage tank carried by said frame for carrying said flowable material to be applied to a surface over which the machine passes, application means for applying the flowable material to the surface and including a transversely extending chamber and a distribution channel therein, said chamber being open on the bottom to permit the material to flow downwardly through the open bottom of the chamber to the surface, flexible aprons extending downwardly from said bottom to define front and rear side walls for said chamber, conduit means extending between said storage tank and said application means to allow the material to flow therethrough and into the distribution channel, valve means for controlling the amount of material flowing to said distribution channel, means for deflecting the discharge of the flowable material from said conduit means in predetermined directions as toward the uphill side of the channel means when the machine is on a sloped surface, and manually adjustable means for controlling said deflecting means and movable to reverse the direction of material deflection when said machine has been turned about to travel in the reverse direction.
Claim 3
Dependent Claim
42 words
An applicator machine according to claim 1 including means for mounting said application means for pivotable movement about a longitudinally extending axis for said machine and relative to the storage tank to facilitate application of flowable material to a sloped roof surface.
Claim 4
Dependent Claim
47 words
An applicator machine in accordance with claim 1 in which a heating means surrounds the bottom of said storage tank to apply heat thereto and further comprises a heating channel extending transversely with said distribution channel to heat the material flowing to and through said distribution channel.
Claim 5
Dependent Claim
46 words
An applicator machine according to claim 1 comprising rolls spaced above said surface for engaging a roll of roofing material to be applied to said surface, and further comprising a plurality of spring plates disposed rearwardly of said rolls for applying pressure to the roofing material.
Claim 6
Dependent Claim
28 words
A machine in accordance with claim 1 in which a silicone rubber coating is provided on said wheels to prevent adhesion of the flowable material to said wheels.
Claim 7
Dependent Claim
27 words
An applicator machine in accordance with claim 1 in which said rear apron is made of rubber and is provided with prongs on the bottom edge thereof.
Claim 8
Dependent Claim
31 words
A machine in accordance with claim 6 in which said prongs have a height of about 10 mm and the spacing between adjacent prong tips on the bottom is 3 mm.
Claim 9
Dependent Claim
33 words
An applicator machine in accordance with claim 1 in which said front apron is made of rubber and is disposed at an angle of about 1.5* to the longitudinal direction of the apron.
Claim 10
Dependent Claim
37 words
An applicator machine according to claim 1 including a trailing means for engaging the surface with a compression force, and means for adjusting the trailing means to control force applied by the trailing means to said surface.
