Abstract: An apparatus and method for treating trees (especially trees of relatively small size or diameter) with a liquid. At least one hole is formed in the trunk of a tree extending into the cambium layer thereof. A bracket is secured to the tree. An upstanding inclined hollow tube, having an inner open end and an outer end, is provided. A resilient bushing is positioned in the inner end of the tube and extends therefrom. A self-sealing bushing is positioned in the outer end of the tube, thereby sealing the tube. The resilient bushing has an aperture formed therein which is substantially identical in size to the hole in the tree. The resilient bushing in the tube is pressed against the trunk of the tree with the aperture thereof positioned substantially coincident with the hole in the tree, thereby providing for liquid communication betweeen the tube and the hole. This pressing further deforms the resilient bushing, thereby forming a substantially liquid-tight seal therebetween.

Abstract: A metal cartridge is driven into a downwardly-inclined bore in the trunk of a tree, and a hyopdermic needle is inserted through a mass of sealable material carried by the rearward end portion of the cartridge and accessible externally thereof. Preferably, the sealable material comprises silicone which is room temperature vulcanizable ("RTV") and may be color coded to readily indicate to the operator the successive stages in the innoculation or other treatment of the tree.The needle is closely guided through the RTV by means of a restricted diameter bore and counterbore in the cartridge, and the liquid is injected into the cartridge and flows out the forward open end thereof. In a preferred embodiment, the cartridge comprises a rifle cartridge from which the primer has been removed. The cartridge is rugged and reliable, inexpensive, and may be driven into the tree trunk by a hammering action.

Abstract: Roof system including a plurality of shingled generally wedge shaped roof members. Each roof member has a long rectangular shape with tile markings on the upper forward surface. The generally wedge shaped roof members include a relatively planar upper surface except for an upward projecting flange that leans forward toward the forward side of the roof member. The lower surface includes a first converging planer lower surface portion extending beyond the position of the upper flange of a shingled lower roof member. The lower surface includes a second converging planer lower surface portion that ends in a rear edge. A border area between the first portion and the second portion is of increased thickness. A mating flange groove is located in the first portion which is arranged and sized to mate over the upper flange and rear portion of a lower shingled roof member.
