Refuse collection devices
First Claim
1. A collection device for a refuse collection vehicle having a refuse collecting container and a suction duct for sucking refuse into the container, the suction duct being connected at one end to the container and at an opposite end being connectable to the collection device, the collection device comprising:
- a refuse inlet for connection to the suction duct,resilient elements surrounding the periphery of the refuse inlet and for forming a seal between the refuse inlet and a surface over which the inlet is travelling,a roller forming one of said resilient elements and extending generally across a front portion of the periphery of the refuse inlet,mounting means rotatably mounting said roller, anda resilient surface on said roller for deforming exactly to the shape of items which pass under the roller whereby to prevent a reduction in the suction as such items are encountered.

Abstract
A refuse collection device comprises a refuse inlet for connection to a suction duct of a refuse collecting container mounted on a vehicle. Resilient elements surround the periphery of the refuse inlet and form a seal between the refuse inlet and a surface over which the inlet is travelling. A roller froms one of the resilient elements and is mounted across a front portion of the periphery of the refuse inlet. The roller has a resilient surface which deforms to allow objects to pass beneath the roller without reducing substantially the seal provided by the roller.

5. A refuse collection device for a refuse collection vehicle having a refuse collecting container and a suction duct for conveying collected refuse to the container, the collection device comprising:
-
a refuse inlet for connection to the suction duct, a suction mouth opening onto a surface from which refuse is to be collected, elements arranged around the suction mouth for forming a seal between the surface and the suction mouth, a rotatable roller forming one of the elements disposed along a leading edge of the suction mouth, a resilient surface on the roller whereby when a roller passes over an object the resilient surface deforms to allow the object to pass the roller without reducing the seal provided by the roller.

6. A refuse collection vehicle comprising a refuse collecting container and a suction duct for sucking refuse into the container, the suction duct being connected at one end thereof to the container and at an opposite end thereof to a collection device comprising a refuse inlet for connection to the suction duct, resilient elements surrounding the periphery of the refuse inlet and for forming a seal between the refuse inlet and a surface over which the inlet is travelling, a roller forming one of said resilient elements and extending generally across a front portion of the refuse inlet, mounting means rotatably mounting said roller for rotation about an axis extending normal to the direction of travel of the device, and a surface on said roller which is highly resilient in a radial direction of the roller whereby, when sizable refuse rolls under the roller, the relevant part of the roller adapts exactly to the outlines of the sizable refuse thus preventing unnecessary widening of the gap between the roller surface and the surface over which the inlet is travelling and preventing any substantial loss of suction.
