Abstract: ABSTRACT OF THE DISCLOSURE A tractor having a driver's cab, an accessory comp-artment in the fender immediately adjacent the door to the driver's cab, the accessory compartment having a cover forming part of the fender and which projects below the edge of the cab door so that when the cab door is closed, it is impossible to raise the cover of the accessory compartment.  In this way, when the door is locked, the accessory compartment is also automatically locked.  The accessory compartment may hold a battery or tools or both.  In the particular form shown, there is a battery compartment and tool compartments adjacent to the battery compartment.  The invention is particularly applicable to the type of tractor which is sufficiently large that steps are required to reach the door of the driver's cab. In such case, the cover for the compartment may also include a downwardly extending part of the fender and one of the steps may be secured to this downwardly extending part.          The inclusion of a downwardly extending part as part of the accessory cover makes it possible when the cover is raised to provide greater access to the battery and also makes it possible to provide an additional tool compartment beneath the battery.

Abstract: METHOD AND CORE BARREL APPARATUS FOR OBTAINING AND RETRIEVING SUBTERRANEAN FORMATION SAMPLES.                       ABSTRACT         Core barrel apparatus and a method for obtaining and retrieving sealed core samples of subterranean forma-tions are disclosed.  The core barrel apparatus comprises inner and outer core barrels.  The upper portion of the outer core barrel is adapted to be connected to a drill string.  A core bit for cutting a core sample is mounted on the lower portion of the outer core barrel.  The inner core barrel comprises a sample chamber for receiving a core sample as it is formed at the bottom of a bore hole and an expansion chamber for receiving sample fluids.          The sample chamber and expansion chamber are selectively connected to one another.  The expansion chamber is sealed closed while the core barrel is lowered into the bore hole and the sample is being cut and received within the sample chamber.  The lower portion of the sample chamber adjacent the core bit is sealed by a flap-valve which includes a flexible flap member.  The flexible flap member is de-flected from its normal form of a flat disc into a semi-cylindrical form and stored adjacent to the inner circum-ferene  of the sample chamber while the sample is being is being cut.  Once the core sample is within the sample chamber, the flap member is permitted to spring into its flat disc form and extend across the opening in the lower portion of the sample chamber in order to seal the core sample within the chamber.  Thereafter the expansion chamber is opened to the sample chamber.  As the apparatus is raised toward the surface and the pressure within the bore hole decreases, the expansion chamber expand  in response to the pressure of the fluid within it and thereby maintains the pressure within the expansion chamber at or relatively near the bore hole pressure.          In one embodiment, the expansion chamber comprises a flexi-ble tube which is preferably expandable both radially and axially.  In other embodiment, the expansion chamber com-prises an axially expandable bellows. In still other em-bodiments, the expansion chamber comprises a cylinder having a movable sealing member therein such as a cup-like member, a piston or a flexible, shaped member.
