Abstract: A high reach self centering hydraulic tree trimmer which consists of first a carriage assembly. The carriage assembly consisting of a top plate and a bottom plate. The plates are separated by spacers and secured together with a plurality of fasteners. A pair of cutting blades are contained between the top plate and the bottom plate. The blades are reciprocal of each other and each have a front end, center region, back end, outer edge, inner edge and a cutting edge extending along the inside edge. The blades are self centering about an object to be cut by pivoting independently from each other They pivot about separate pivot points in the center region of the blades. A pivot pin or bolt is used as a pivot device extending from the top plate to the bottom plate. A hydraulic cylinder is used to operate the blades. The hydraulic cylinder is pivotally attached to the back ends of the blades. This operation causes the blades to pivot independently about the pivot points resulting in the cutting surfaces closing upon each other. There is included an attachment means connected to the carriage assembly for attaching the tree trimmer to a bucket or other lifting means on a tractor or other such vehicle. There is also an optional positioning apparatus for pivoting the tree trimmer for cutting trees, branches, limbs or brush at different angles.

Abstract: The present invention is a system and method for an easy installation storm door for installation in a home. The door system may include a door panel that is mounted onto two vertical z-bar frames such that the door system can be installed in a left hinge or right hinge format. The z-bar frames are precut at the factory to be shorter than a standard doorframe so that they do not have to be cut during installation. Also included in the system are top and bottom expanders that fit onto a top and bottom side of the door panel so as to selectively adjust the vertical height of the door panel. The top and bottom expanders further insure a reasonable air and moisture barrier between the interior and exterior of the home. The door system further includes a lock assembly that is pre-installed such that it can be utilized whether the door system is installed in a left hinge or right hinge format. The lock system may include a lockbody that includes duplicate hardware such that the door panel can be situated in the doorframe in a right hinge or left hinge format without having to adjust the position or orientation of the lockbody.

Abstract translation: 本发明是用于安装在家中的易于安装的风暴门的系统和方法。 门系统可以包括安装在两个垂直z形框架上的门板，使得门系统可以以左铰链或右铰链格式安装。 z型钢框架在工厂预先切割为比标准门框更短，以免在安装过程中不要被切割。 还包括在系统中的顶部和底部扩张器适合于门板的顶部和底部，以便有选择地调节门板的垂直高度。 顶部和底部的膨胀器进一步确保了家庭内部和外部之间合理的空气和湿气屏障。 门系统还包括预先安装的锁组件，使得无论门系统是安装在左铰链还是右铰链格式中都可以使用。 锁定系统可以包括锁体，其包括重复的硬件，使得门板可以以右铰链或左铰链格式位于门框中，而不必调整锁定体的位置或取向。
