  • The present invention can be broken up into 4 main sections: a base mounting frame, a rotating frame, a squeegee main frame, and a squeegee wing actuator arrangement. Refer to FIG. 2. The base mounting frame serves as means for mounting the rotary actuator (7) and for mounting the squeegee apparatus to the rear of an asphalt sealant machine. The rotary actuator (7) provides additional control of the asphalt sealant material. The base mounting frame has a large 90 degree angle piece (1) with a center-hole large enough in diameter for a rotary actuator and serves as means to mount the rotary actuator. Mounting brackets (2) are attached at the ends of the angled piece (1), consist of 2 vertical slots for height variation (3), and serve as means to attach the squeegee apparatus to the back of an asphalt sealant machine.
  • Refer to FIG. 2. The rotating frame serves as means to connect the squeegee main frame to the rotary actuator and comprises of a rectangular channel piece (6) to act as a base to attach to the squeegee main frame; attached to the rectangular channel piece is a piece (5) for attaching the rotary actuator, which consists of a specific hole pattern as the rotary actuator; and attached on top of the hole patterned piece (5) is a rectangular shim (4) with a center-hole for smooth rotation of the rotating frame. The rotary actuator shall be sized accordingly to specific applications in relation to the application's weight and torque requirements and shall receive power from the asphalt sealant machine it is mounted to. FIG. 6 shows an example of mounting the apparatus and power lines (31) to the apparatus from a sealant machine.
  • Refer to FIG. 3. The main squeegee frame attaches to the base mounting frame and consists of means for attaching squeegee blades and the squeegee wing actuator arrangement. The main squeegee frame consists of two long pieces of angle iron for the front (1F) and rear (1R) squeegees and brackets for attaching the two pieces together (2). Both angle iron pieces have linearly spaced holes for attaching the squeegee blades. The ends (6) of the rear angle iron piece are reinforced for attaching the squeegee wing actuator arrangement. The squeegee blade (3) is secured using heavy industrial nuts and bolts (5) and is placed between the squeegee angle iron pieces (1F, 1R) and flat rectangular reinforcing pieces (4). Both rectangular reinforcing pieces have linearly spaced holes for attaching the squeegee blades.
  • Refer to FIG. 4. The squeegee wing actuator arrangement serves as means for rotating the squeegee wings and comprises of a linear actuator and rotation piece. The linear actuator (10) should be sized accordingly for the specific application and shall receive power from the sealant machine the squeegee apparatus is mounted to. One end of the linear actuator connects to the squeegee main frame via a mounting bracket (6), and the opposite end attaches to the rotating wing piece (11).
  • Refer to FIG. 5. The rotating wing piece consists of a custom ram bracket (20), a cylindrical spacer (21), a circular disk (22), wing attachments (24), and means for attaching to the squeegee main frame (23). The ram bracket (20) translates the linear actuator motion to angular rotation and connects to a circular disk (22) via spacing cylinder (21). The squeegee wing (24) attaches to the circular disk (22). The rotating wing piece is then mounted to the squeegee main frame via a secured rod (23) and the linear actuator. Each piece within the rotating wing piece is position to provide 90 degrees of wing rotation. The squeegee wing comprises of a similar assembly as the squeegee main frame. The squeegee blade is secured using heavy industrial bolts (25) and is placed between an angle iron piece (24) and a flat rectangular reinforcing piece (26).
