Abstract

935,727. Road paving machines. PRECO Inc. Jan. 12, 1962, No. 1300/62. Class 107. A paving machine comprises draft arms 50, 51 extending rearwardly from transverse pivot axes 52 and having mounted on their rear ends the end portions of an elongated torsionally flexible screed 44, means such as screws 25 for depositing paving material 35 adjacent the forward edge of the screed, tamping bars 42 forming a mat on which the screed rides and adjusting means such as screws 56, 57 operable to vary the angle of attack at which the respective screed end portions engage the material. Combined with the machine are means such as a potentiometer (not shown) adjustable to represent the desired transverse inclination of the mat surface and sensing means such as a pendulum, mounted on a gantry beam itself mounted on arms 70, 71 secured to the screed ends and responsive to differences in the height of the two ends and their respective angles of attack. A potentiometer is associated with the pendulum and output signals from this and the already mentioned potentiometer are supplied to a servo amplifier which produces a signal representing the difference between the desired inclination of the mat surface and the inclination of the surface being currently laid. This signal is shown on a meter 125a, which may be mounted on a casing 103 housing the first-mentioned potentiometer, as a guide for the manual adjustment of the means 56, 57 and optionally drives a motor 120 connected to one or both the means 56, 57 to maintain the desired transverse inclination of the mat surface. The beam 84 may be mounted on the arms 70, 71 at any one of points 74, 74a, 74b. In another embodiment, Fig. 5, arms 70a, 70b pivoted at 124 on the draft arms 50, 51 are connected by a link 125 to the screed side frames 46 and carry a beam 84 as already described.
