Abstract: A tree pruner has a extension rod, a cutting set and a pull cord. The cutting set is mounted on the top end of the extension rod and has a stationary blade, a pivoting blade, an actuating lever and a pinion gear. The stationary blade is securely connected to the top end of the extension rod. The pivoting blade is pivotally attached to the stationary blade and has multiple driven teeth. The actuating lever is pivotally attached to the stationary blade and has multiple actuating teeth. The pinion gear is rotatably mounted on the stationary blade and engages the driven teeth on the pivoting blade and the actuating teeth on the actuating lever. Accordingly, the cutting set can easily cut off a tree branch, and the force applied to the pull cord is magnified at the blades of the tree pruner.

The movement of the movable jaw is confined by the first stop ridge and the second stop ridge in conjunction with the arresting projection of the fixed jaw.

Abstract: The shear blades of a lawn edge trimming shears are angularly relatively displaceable about the pivotal coupling between the blades under the action of a spring restored motion conversion means operable to convert downwards translational motion imparted to the conversion means by the application of a downwards manual force applied at the single handle with which the shears is provided, into a torque acting to produce relative angular displacement, about their pivotal coupling, between the shear blades.

Abstract: A hand-held power-operated blade-actuating or other work member actuating device, especially useful as shears for processing comestible products such as fowl. A servo mechanism and linkage connected with a movable blade and a finger control causes controlled powered movement of the blade in coordination with the finger control. A fixed blade and a pivoted blade are insertable and removable as a unit from a hand-held frame in which the fixed blade is restrained against rotation relative to the frame. The blades and frame are constructed so the blades are insertable or removable only when closed. In a preferred embodiment the fixed blade is retained in part by two load bearing pins extending from the frame and located substantially diametrically opposite each other relative to the pivot axis of the movable blade.

Abstract: In pruning shears a rope-and-pulley device is incorporated between the shears legs in such a manner that by pulling the free end of the rope an amplified closing force is obtained. For convenient remote operation one shears leg force lever arm is connected fixedly or detachably to a handle of any desired length, by a handle securing coupling which extends parallel to the shears leg. An opening spring biases the shears in the opening direction.

Abstract: An improved combination wire installation and cutting tool for installing the ends of telephone circuit conductors into known quick clip connectors, following which the stubs on the free ends of the conductors are cut to predetermined lengths, so as not to interfere with adjacent conductors.

Abstract: A strap cutter is secured to the top structure on an oil well casing and as the discharge pipe supporting a submersible pump is withdrawn, the cutting head of the strap cutter engages with and cuts the straps which secure the pump power cable to the discharge pipe. The strap cutter is manually guided into place but employs the upward motion of the discharge pipe string to supply the cutting force. The method comprises the use of the upward motion to accomplish the cutting step.

Abstract: A shearing device is disclosed for severing trees and the like. The device is vehicle mounted, preferably on the front of a tractor, so that forward movement of the tractor causes shearing of a tree in contact with the device. The device includes a frame member with a pair of forwardly extending spaced arms one of which has a pivot member mounted thereon, with the pivot member carrying a severing element that can be moved in an arc toward and away from the other arm of the frame member. A tree brought into contact with the severing element will be severed as the severing element is caused to move toward the other arm of the frame member due to continued forward movement of the vehicle. After a tree has been severed, the pivot member is preferably biased to automatically return to normal position near the end of the arms of the frame member with the severing element at least partially spanning the space between the arms.
