Assignee:

Conestoga Wood Products, Inc. - East Earl PA

International Classification:

B26D 128
B27G 1304

US Classification:

29105R

Abstract:

A cylindrical rotary cutting head rotatable about a longitudinal axis having a plurality of helical slots in which a plurality of bits carrying cutting edges are retained in the lateral direction by means of set screws which bear against a "V" groove in an inclined face of the bit and in the vertical direction by plurality of cooperating serrations on an opposite face of the bit and in one slot wall.

Abstract:

A lifting and towing unit mountable on a fifth wheel of a towing vehicle has an anchoring frame assembly with a king pin for coupling to the towing vehicle fifth wheel and a lifting frame assembly adapted to support a portion of a mobile load and to be releasably attached thereto and to the anchoring frame assembly in a fixed relation thereto. The unit also includes an arrangement in the form of a four-bar linkage interconnecting and mounting the lifting frame assembly rearwardly of and to the anchoring frame assembly for pivotal movement relative to the frame of the towing vehicle between lowered and raised positions. In the lowered position, load engaging structure of the lifting frame assembly is capable of being placed in a supporting relationship with the mobile load portion for lifting the mobile load into a towing relationship behind the towing vehicle, whereas in the raised position the lifting frame assembly load engaging structure is capable of supporting the mobile load at the portion thereof to maintain the mobile load in the towing relationship behind the towing vehicle. In the towing relationship, the anchoring and lifting frame assemblies form a substantially rigid towing beam interconnecting the fifth wheel of the towing vehicle and the mobile load such that the only load forces are a vertical downward force on the fifth wheel of the towing vehicle and a vertical downward force on the wheels of the towed mobile load.

International Classification:

B60D 112

US Classification:

280432

Abstract:

A hitch uncouple detecting and signaling apparatus, being applied to a trailer hitch ball member, includes a plunger rod reciprocally mounted vertically through the ball member. The rod is longer than the ball member, allowing the rod to extend either above or below opposite upper and lower ends of the ball member. The rod is composed of electrically nonconductive material capable of being trimmed to a length which will exceed the ball member height at least by a desired amount. An electrical circuit adapted for connection to a source of electrical power includes an operator signaling device and a pair of contacts. One contact is carried by a lower end of the rod and the other contact is defined on the lower end of the ball member, which preferably is composed of electrically conductive material. A resiliently stretchable band interconnects the rod and the ball member so as to bias the rod upwardly with its upper end extending above the ball member and the one contact electrically engaged with the other contact causing activation of the operator signaling device. Upon seating of the trailer hitch socket member on the ball member, the stretchable band yields to permit the rod to move downwardly, displacing the one contact below the other contact and deactivating the operator signaling device.

International Classification:

B60P 312

US Classification:

280402

Abstract:

A recovery unit for use by one truck tractor in towing another disabled truck tractor has an anchoring frame assembly with a king pin for coupling to a fifth wheel of the towing tractor and an attaching frame assembly with a king pin for coupling to a fifth wheel of the disabled tractor. The attaching frame assembly is mounted for pivotal movement relative to the anchoring frame assembly between stored and extended conditions. Actuating cylinders and an auxiliary frame assembly are selectively operable to pivot the attaching frame assembly relative to the anchoring frame assembly between the stored and extended conditions and to pivot the attaching frame assembly to and from an erected position relative to the anchoring frame assembly once the attaching frame assembly has been first moved to its extended condition and coupled to the fifth wheel of the disabled tractor. When the attaching frame assembly is moved to its erected position, this results in the frame of the disabled tractor being placed in a raised towing position. In the erected position, the attaching frame assembly can be rigidly locked to the anchoring frame assembly to form a rigid beam extending between and interconnecting the respective fifth wheels of the tractors.
