FIELD OF THE INVENTION
This invention relates to an apparatus which installs survey Hubs and feathers at the top of a survey Hub and the method of use of the apparatus.
BACKGROUND OF THE INVENTION
Surveyors install or place Hubs in accordance with engineering drawings. Frequently, the installation will be in or through a hard or rocky surface including asphalt. Use of hammers, including sledge hammers, are problematic regarding the penetration of such surfaces by striking a Hub. The top of the Hub may also be required to be placed below the surface of the ground or other surface where the Hub is to be positioned. The use of sledge hammer, in such a condition, can result in the formation of a large hole in the ground or surface. This invention provides a tool for both installation of a Hub and a Feather at the top of the Hub in either hard surface conditions or where the Hub top will be beneath the surface.
The patents referred to herein are provided herewith in an Information Disclosure Statement in accordance with 37 CFR 1.97.
SUMMARY OF THE INVENTION
The Apparatus (1) disclosed herein is for placement of a Hub is comprised of a rod (100) having a penetration anvil (200) and a penetration point (220) at a first end (120) and a hub receptacle (300) and a hub receptacle anvil (320) at a second end (140). A hammer (400) is formed intermediate the first end (120) and the second end (140) which may exert force against either the penetration anvil (200) or the hub receptacle anvil (320). A feather receptacle (400) is formed proximal the hub receptacle (300). A feather hammer (420) is received by the feather receptacle (400) for the placement of a feather at the Hub top.

DETAILED DESCRIPTION
FIG. 1 illustrates A Survey Hub Installation Apparatus (1) showing an elongated rod (100) being generally cylindrical and formed of a rigid material including metals and having an elongated rod diameter D2 (110). The rod (100) has a first end (120) and a second end (140) and a rod axis (160) from the first and (120) to the second end (140). The rod (100) has a penetration point (200) at the first end (120) and a penetration anvil (220), formed of rigid materials including metals, proximal the first end (120). The penetration point (200) will be pointed and formed of materials, including metals, capable of penetration of hard soils, asphalt and other surfaces encountered in survey work. The penetration anvil (220) is affixed to the rod (100) by penetration anvil affixing means (240) including welding and metal forming and is generally disk shaped.
Seen in FIGS. 1, 4, and 7, the rod (100) at the second end (140) has a hub receptacle (300) which is generally rectangular or square, but may be circular, and having a hub receptacle wall (310) which has a hub receptacle wall dimension (315). The hub receptacle (300) is recessed and sized and shaped to receive a survey hub (600) at a survey hub top (630). A hub receptacle anvil (320), illustrated in FIGS. 1 and 4, is affixed to the rod (100), proximal the hub receptacle (300), by hub receptacle anvil affixing means (340) including welding and metal forming. The hub receptacle anvil (320) is generally disk shaped and formed of rigid material including metals.
A least one generally cylindrical hammer (400), shown in FIGS. 1 and 2, is generally formed of a rigid material including metals, has a hammer first end (420), a hammer second end (440) and a hammer aperture (460). The hammer aperture is sized and shaped to slidably receive the rod (100). The at least one hammer (400) is positioned intermediate the penetration anvil (220) and the hub receptacle anvil (320). The penetration anvil (220) and the hub receptacle anvil (320) are flat facing the at least one hammer (400). The at least one hammer (400), in the preferred embodiment, is comprised of at least two hammers (400) connected by a generally cylindrical hammer sleeve (480). The hammer sleeve (480) is sized and shaped to be slidably received by the rod (100) and to be seized by a survey operator.
A feather hammer assembly (580), illustrated in FIGS. 1, 4, 4A, 5, 5A, 6 and 7, is formed integrally into the hub receptacle wall (310) and affixed to the rod (100) or is formed to be removably received into a feather hammer assembly slot (502) and removably affixed to the rod (100). The feather hammer assembly (580) includes a feather receptacle (500) formed in the hub receptacle wall (310) or positioned in the hub receptacle wall (310) as a part of a removable feather hammer assembly (580). The feather receptacle (500) is an aperture in the hub receptacle wall (310) or in the removable feather hammer assembly (580) which is parallel to the rod axis (160). A feather receptacle aperture (510) is āUā shaped at and facing the second end (140) to allow a feather sleeve (560) to be received into the feather receptacle (500) so as to position a feather sleeve (560) at or somewhat distal to the extremity of the second end (140) thus preventing unwanted contact between the a feather pin (570) and the survey hub top (630) prior to the operation of positioning a feather (550) at the survey hub top (630). A feather sleeve (560) has a feather sleeve diameter D4 (565) which is sized to be loosely friction retained in the feather receptacle (500) which has a lesser diameter than a feather receptacle aperture diameter D3 (515).
A generally elongated and cylindrical feather hammer (520), seen in FIGS. 1, 5, 5A, 6 and 7, composed of a rigid material including metals, has a feather hammer diameter D5 (530) which is less than the diameter of the feather receptacle aperture diameter D3 (515) thereby allowing the feather hammer (520) to be slidably received while being approximately the diameter of a feather sleeve diameter D4 (565) to impart force against the feather sleeve (560) thereby urging an outwardly extending tab shaped feather pin (570) to penetrate a survey hub top (630) and hence positioning an upstanding feather strand (555), generally composed of brightly colored plastic fibers, for construction viewing of a survey hub (600). The feather pin (570), illustrated in FIGS. 5 and 6, expected in the generally available feather sleeves (560) is an upstanding metal tab which penetrates the survey hub top (630) and positions the feather (550) to be seen by construction workers. It is recognized that the feather (550) and survey hub (600) are not inventions disclosed or claimed herein. However, the claim recitation regarding the feather pin (570) and survey hub (600) are meant to illustrate that a feather pin (570) may be composed of a metal tab or another mechanism, such as an adhesive, that would affix a feather (550) to the survey hub top (630). The survey hub (600) commonly seen in survey work is a wooden stake, illustrated in FIG. 2. It will be known to those of ordinary skills that survey hubs (600) may be composed of other materials.
The feather hammer (520) is retained and guided by a feather hammer guide (540), illustrated in FIGS. 4, 6 and 7, which receives the feather hammer (520) by an aperture parallel to the rod axis (160). The feather hammer guide (540) is affixed to the rod (100) by feather hammer retainer affixing means (544) including welding and metal forming.
When the feather hammer assembly (580) is removable, as seen in FIGS. 6 and 7, there is a feather hammer guide slot (541), on each side of the feather hammer assembly (580) which is parallel to the rod axis (160), intermediate the feather hammer guide (540) and the rod (100) and aligned with a feather hammer retainer clip (545). The feather hammer retainer clip (545), shown in FIG. 7, is affixed by retainer clip retainer means including welding and metal forming to the rod (100). The feather hammer retainer clip (545) provides a spring clip function by outwardly extending arms, having a spring function, which terminate in arm tips formed and shaped to be snap received into the feather hammer guide slots (541).
A feather hammer feather slot (543), illustrated in FIGS. 6 and 7, is an aperture parallel to the feather hammer (520) extending downwardly from the outermost portion of the hub receptacle wall (310) to a position proximal the feather hammer guide (540). The feather hammer feather slot (543) receives a feather (550) composed of multiple brightly colored plastic feather strands (555) secured in at least one cylindrical sleeve, affixed to the feather sleeve (560), and guided downwardly through the feather hammer feather slot (543).
