Abstract
Abstract An over-the-road type vehicle for transport and powering of a seismic hydraulic vibrator which is adapted to operate in either one of two modes of operation. A first mode is the conventional mode wherein the vehicle is operated over large distances at varying road speeds, obtained by use of multiple gear ratios, and varying engine speeds. The second mode of operation is in a single value of road speed, with engine under control of a governor, to operate at constant high speed, and the movement of the vehicle is by successive short traverses at constant speed. In this second mode of operation the single engine alternately powers the hydraulic vibrator, and with the engine still at high speed, then moves the vehicle to a new vibration point a short distance away. A high energy efficiency is provided by the use of a mechanical, rather than hydraulic drive system, and a high time efficiency is provided by a novel style of clutch that can start the vehicle from rest with the engine at maximum speed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
191 words
In a vehicle having only a single engine, for transport and powering of a seismic hydraulic vibrator for over the road use, comprising; (a) means to carry a seismic hydraulic vibrator on said vehicle, and to drive an hydraulic pump from said single engine, for pressurizing a selected first fluid for powering said vibrator, and means to control said vibrator; (b) gear transmission means between said single engine and the wheels of said vehicle; the improvement in means to repeatedly rapidly start said vehicle, for short distance travel, while said engine is running continuously at or near maximum speed; comprising; (c) a first wet disc clutch means connected into the drive system between said single engine and said wheels; said first wet disc clutch means capable of repeatedly starting said vehicle from rest, at or near maximum engine speed; whereby said single engine operating at or near maximum engine speed alternately powers the operation the said vibrator when said vehicle in at rest and powers operation of traversal of the vehicle over a series of about equal new vibration points of short distances said operations being at a constant gear ratio.
Claim 2
Dependent Claim
