Abstract
The screed assembly includes a screed plate and a screed frame. The screed plate includes a notch and the screed frame includes a tab that is inserted into the notch on the screed frame such that only screed plates and screed frames which include proper mating notches and tabs may be assembled together on road paving machines. In a preferred form of the invention, the width of the tab is approximately equal to the width of the notch to prevent lateral movement of the screed plate with respect to the screed frame when the screed plate is subjected to lateral impacts and forces during operation of the road paving machine.
Claims18
A screed assembly for a paving vehicle, the screed assembly comprising:
- a frame connectable with the vehicle and including a tab;
- and
- a screed plate having a first, generally vertical wall portion including a notch, the notch extending into the wall portion so as to be at least partially bounded by two facing surface sections of the plate, and a second, generally horizontal wall portion connectable with the frame, the notch being configured to receive the frame tab such that when the plate second portion is connected with the frame, the tab is disposed within the notch generally between the two plate surfaces and the mating tab and notch generally prevent lateral movement of the plate relative to the frame.
A screed assembly for a paving vehicle, the screed assembly comprising:
- a frame connectable with the paving vehicle and having a wall portion including a notch, the notch extending into the wall portion so as to be at least partially bounded by two facing surface sections of the wall portion;
- and
- a screed plate having a first, generally vertical wall portion including a tab, the tab being integrally formed with the vertical wall portion, and a second, generally horizontal wall portion connectable with the frame, the tab being disposable within the frame notch such that when the plate second portion is connected with the frame, the tab is disposed within the notch between the two wall surface sections and the mating tab and notch generally prevent lateral movement of the plate relative to the frame.
A screed assembly for a paving vehicle, the screed assembly comprising:
- a frame connectable with the vehicle and including a tab;
- and
- a screed plate having a first portion including a notch and a second portion connectable with the frame, the plate having a thickness and the notch having a depth that is less than the thickness of the plate, the notch being configured to receive the frame tab such that when the plate second portion is connected with the frame, the tab is disposed within the notch and the mating tab and notch generally prevent lateral movement of the plate relative to the frame.
