Tree Surgery Patents (Class 47/8)
  • Patent number: 8726567
    Abstract: The invention provides a hand-held electronic device for injecting an agent into a tree with continuous pressure sensing technology for real-time measurements of the pressure within the tree. The pressure measurement information is conveyed to an onboard central processing unit for data collection, analysis and optimization of the speed of injecting the agent into the tree. By continually monitoring the pressure and injection power, the injection pressure can be modified to adapt to back pressure fluctuations. In one embodiment of the invention the agent is injected into the tree under a preprogrammed pressure profile. In another embodiment of the invention the agent is injected into the tree under a variable pressure profile until the fastest injection time is obtained.

  • Publication number: 20130025193
    Abstract: A tree trimming method that is related to a convex method of pre-determined angular trimming of deciduous trees. The methodology uses pre-determined angle cuts for deciduous vegetation to re-orient new growth and shape shade trees, shrubs and ornamental trees. This pre-determined “convex cut” makes the curved cuts reorient the tree limbs to a pre-desired radial shape and encourages the tree limbs to re-orient and grow. This results in the deciduous tree canopy that is round or radial in shape. The pre-determined angle cutting proves useful for either on the outside perimeter or for clearing inside the tree canopy for power lines. Essentially any pre-determined angle of clearing or directional shaping to re-orient new growth can be done with this cutting method.

  • Publication number: 20110041396
    Abstract: A tree trimming method that is related to a convex method of angular trimming of trees. The methodology uses angle cuts for tree trimming and shaping of all shade trees, evergreen trees, and ornamental trees. The angle cutting of limbs is in a “convex cut”. This makes curved cuts bring the tree limbs in a radial shape and encourages them to grow which results in the tree canopy to be round or radial in shape. Angle cutting proves useful either on the outside perimeter or useful in vertical clearing inside the tree canopy for clearance (for power lines and such). Essentially any angle of clearing or directional shaping can be done with this of cutting method—under the canopy, on the sides, at the top, or clearing pathways through the middle without damage to the trees.

  • Patent number: 6629384
    Abstract: A method of deflowering hardwood trees (dicots) comprises the steps of evaluating the physiological maturity of male and female flowers of a dicot, and injecting a solution containing synthetic indolebutyric acid (IBA) into vascular tissue of the tree when male and female flowers approach physiological maturity at or prior to fertilization. In accordance with a preferred method, the injected solution is about 4% synthetic IBA in water, and five milliliters of the solution is injected into the vascular tissue through each of a plurality of injection holes bored at spaced intervals about the circumference of the trunk of the dicot. The method causes delayed shedding of staminate flowers and early abortion or suppression of pistillate flowers, thereby preventing the development of fruit heads and the production of seed known to be a nuisance.

  • Patent number: 6484440
    Abstract: A spike, drivable into the trunk of a tree, includes a hollow body which provides a storage chamber for a water soluble compound such as a pesticide or fertilizer. The spike has a generally pointed first end which facilitates driving the spike into a tree trunk. The hollow body is equipped with bleed apertures near the pointed end, so that when the spike is driven into the trunk of a tree, the storage chamber is coupled to the vascular system thereof. The spike is supplied with a resilient sheath that seals the bleed apertures during shipping and handling. As the spike is driven into a tree trunk, the sheath is peeled off the body, thereby exposing the bleed apertures to the tree's vascular tissue and forming a gasket between the spike body and the aperture created by driving the spike into the trunk.
