Abstract: A skiving apparatus for simultaneously skiving the outer and inner surfaces of an end of reinforced hose. The apparatus comprises an outer diameter cutting tool, an internal skiving mandrel and a bracket for holding the outer diameter cutting tool and the internal skiving mandrel in a substantially perpendicular relation. The internal skiving mandrel has a nose for coaxially receiving a hose end thereover, spiral cutting threads and a stop collar. To achieve the desired simultaneous skiving effect, the internal skiving mandrel and the outer diameter cutting tool have a coincident cutting direction. Thus, when the hose is fed over the mandrel and the apparatus is rotated the simultaneous skiving of the inner and outer surfaces of the hose is accomplished.

Abstract: A control apparatus for a pavement breaker which includes a carriage, a lifting means for raising and lowering an impact arm which impact arm includes a tool for impacting a surface, mounted on one end and an oscillating member mounted on the other end. The control apparatus basically includes electrical apparatus for measuring the total weight being applied through the lifting means to the tool when it is in contact with the surface to be impacted and apparatus for limiting the amount of horizontal force that can be applied to the impact arm during the process of impacting the surface of the earth. A processor receives an electrical signal from the electrical apparatus which is applied to the lift control apparatus in a manner to stabilize the lifting force. A signal output is generated by the horizontal force limiting apparatus when a predetermined amount of horizontal force is received by the electrical device.

Abstract: This invention describes an apparatus for breaking a hard surface such as a concrete road or bridge deck and essentially consists of a support for a torsional spring which is horizontally fixed to the support with a spaced rotational journal so that the torsional spring is mounted substantially horizontally. An oscillating member of desired mass characteristics is attached to the torsional spring with a force generating apparatus such as a hydraulic vibrator on one end of the oscillating member and a road crushing tool on the opposite end of the oscillating member. The oscillating member is attached rigidly to the torsional spring. Apparatus is also provided for positioning the impact or road crushing tool against the surface to be crushed and for maintaining the tool in that position during the crushing operation.The hydraulic vibrator, when it is operated, causes an axial oscillation in the torsional spring/mass system.

Abstract: An apparatus for splitting logs into billets and having a pivoting splitter head mounted at one end of an elongated log support upon which logs are placed for splitting. The splitter head is supported by a pin extending from a splitter head mount attached to the log support toward a pusher that forces the log into the splitter head. Platforms are attached to the pusher and extend therefrom along the sides of the log support to receive the billets into which a log is split, the attachment of the platforms to the pusher maintaining the platforms in lateral alignment with the log as the log is split. The apparatus is mounted on a wheeled chassis having a trailer tongue at one thereof for towing the apparatus to a work site.

Abstract: An improved suspension assembly for a seismic exploration vehicle having a substantially rigid main frame supported and moved by track assemblies disposed along opposing sides of the frame. The suspension assembly includes two bogies which engage the inner periphery of a track on one side of the vehicle and each of the two bogies is mounted on one end of a bogie arm that is pivotally connected, at the other end of the bogie arm, to a central portion of a walking beam pivotally connected to the vehicle frame. End portions of the walking beam overlay the distal ends of the bogie arms and air bags are mounted between the distal ends of the bogie arms and the ends of the walking beam to bias the bogie arms in a downward direction.
