## Background
FIELD OF THE INVENTION
The present invention relates generally to the field of erosion control equipment and more particularly, but without limitation, to an erosion control blanket dispensing apparatus configured to support and dispense erosion control blankets.
BACKGROUND
The banks of dunes, cliffs, sloping grounds, and other properties are subject to highly undesirable erosion. Due to the cycling of temperature, moisture, freezing and other conditions, the surface layers thereof typically are unstable and tend to creep downwardly in shear. Sooner or later their facings give rise to serious dislocations unless steps are taken to secure the unstable surface layers against erosion.
In order to prevent erosion and for both aesthetic and environmental protection reasons, it is often necessary or desirable to grow ground vegetation because the roots of vegetation planted along such properties tend to secure the unstable surface layers against erosion. The successful sprouting and growth of ground vegetation planted on these areas, however, is often prevented by the soil erosion which the planted vegetation is designed to inhibit, the erosion frequently carrying away at least some portion of the soil before the vegetation takes hold. Furthermore, adverse weather may inhibit the vegetation growing process. For example, in a storm, the banks of such properties are subjected to powerful winds and rain that often carry away the facing soil, and with it, any vegetation rooted therein.
To alleviate this problem of eroding vegetation roots, it is now a common practice to lay erosion control blankets over grass seed. The protective covering most used is what is best termed a blanket or mat comprised of netting and underlying excelsior. At the job site, the erosion control blanket bundles are unrolled in a side-to-side relationship along the earth area to be protected against erosion, and are secured along the sides of one another and to the underlying ground area with the use of a spaced series of conventional ground staple members, which may be made of steel, wood, plastic or starch. The installed erosion control blankets generally have parallel sides and abut one another to form a substantially solid surface to shield the underlying earth area, and thus the planted ground vegetation therein, from wind and rain erosion forces. The erosion control blanket must be fastened in place in the ground so that it will not be displaced from the desired location by weather effects such as rain, water runoff or wind.
In order to install erosion control blankets, a user must roll the blankets over the ground. This type of installation requires the user to exert physical force in a bent over position which leads to back, neck and knee problems. After the erosion control blankets are installed, the blankets must then be fastened to the ground. Manually rolling out and securing the erosion control blankets onto the ground and fastening these blankets to the ground with devices that require manual operation is slow and inefficient.
Therefore, what is needed is a device that enables a user to efficiently install erosion control blankets while using minimal manual labor. It is to these and other improvements that preferred embodiments of the present invention are generally directed.

Referring now to the drawings, and in particular to an example of a preferred embodiment of the present inventive erosion control blanket dispensing apparatus 100, also referred to herein as apparatus 100, as shown in FIG. 1. In a preferred embodiment, the apparatus 100 includes a mounting plate 102 that is coupled to a transport vehicle 104, such as a T190 compact track loader by the Bobcat Company of West Fargo, N. Dak. USA, which has been found useful in utilizing the apparatus 100. However, those skilled in the art will recognize that the present inventive erosion control blanket dispensing apparatus 100, may be attached to vehicles other than the T190 such as tractors, four wheel drive vehicles, or other suitable vehicles. It is further noted, that the selection of the T190 as a suitable vehicle for use with the apparatus 100 has been made to enhance an understanding of the invention by those skilled in the art, and does not impart to the present invention, or impose upon the present invention any limitations.
Preferably, the apparatus 100 further includes a rotary drive 106 secured to the mounting plate 102, and a blanket spindle 108 communicating with and responsive to the rotary drive 106. The rotary drive 106 controls an angular position of the blanket spindle 108 relative to the mounting plate 102.
FIG. 1, further shows a spindle support structure 110 disposed between and communicating with the rotary drive 106 and the blanket spindle 108; and a drive mount 112 attached to the rotary drive 106 and supporting the spindle support structure 110. In a preferred assembly process of the apparatus 100, the drive mount 112 is secured to a first end of the rotary drive 106, the spindle support structure 110 is lowered onto a second end of the rotary drive 106 and lightly fastened to the rotary drive 106, the spindle support structure 110 is aligned with, and securely fastened to the drive mount 112, then the spindle support structure 110 is securely fastened to the rotary drive 106.
Preferably, the apparatus 100 further includes a rotary hub assembly 114 disposed between the blanket spindle 108 in the spindle support structure 110. The rotary hub assembly 114 accommodates rotation of the blanket spindle 108 when installing an erosion blanket adjacent the earth.
FIG. 2 shows the rotary drive 106 includes an attachment plate 116 for securement of the rotary drive 106 to the mounting plate 102, and a plurality of fasteners 118 to secure the spindle support structure 110 to the rotary drive 106. The use of a hydraulic rotary actuator, such as a L20 series rotary actuator (with a 180° span of rotation) by Helac Corporation of Enumclaw Wash. USA, as the rotary drive 106 has been found useful as a preferred best mode of enabling the apparatus 100. However, those skilled in the art will recognize that an electric motor, such as a DC stepper motor, or a pneumatic motor could easily accommodate and fulfill the functional requirements of the rotary drive 106.
The use of the rotary drive 106 allows an operator of the transport vehicle 104 (of FIG. 1) to radially position the blanket spindle 108 anywhere along a 180° ark. That is, from being parallel to the mounting plate 102 and extending out to the left of the transport vehicle 104, to being parallel to the mounting plate 102 and extending out to the right of the transport vehicle 104, and to do so without having to leave the cab of the transport vehicle 104.
FIG. 3 shows an alternative embodiment that employs a hydraulic cylinder 120, to control the angular position of the blanket spindle 108 relative to the mounting plate 102. Preferably, the hydraulic cylinder 120 is secured at a first end 122 to the mounting plate 102 via a first cylinder mount 124 (which in a preferred embodiment is a first shaft 124), and secured at a second end 126 to the spindle support structure 110 via a cylinder bushing 128.
In the preferred alternative embodiment, the hydraulic cylinder 120 allows an operator of the transport vehicle 104 (of FIG. 1) to radially position the blanket spindle 108 anywhere along a 90° ark. That is, from being perpendicular to the mounting plate 102 and extending out directly in front of the transport vehicle 104, to a position of being parallel to the mounting plate 102 and extending out to the left of the transport vehicle 104.
Alternatively, by manually repositioning and securing the first end 122 of the hydraulic cylinder 120 to the mounting plate 102 via a second cylinder mount 130 (which in a preferred embodiment is a second shaft 130), the operator is able to position the blanket spindle 108 anywhere along a 90° ark extending in the opposite direction. That is, from a position of being perpendicular to the mounting plate 102 and extending out directly in front of the transport vehicle 104, to a position of being parallel to the mounting plate 102 and extending out to the right of the transport vehicle 104. In a preferred alternative embodiment, once the operator has selected which cylinder mount 124, 130 the hydraulic cylinder 120 is to be attached to, the operator can control the radial angular position of the blanket spindle 108 anywhere along the 90° ark from within the cab of the transport vehicle 104.
FIG. 4 shows the apparatus 100 includes an adjustable stop 132 disposed between the blanket spindle 108 in the spindle support structure 110. The adjustable stop 132 controls the angular position of the blanket spindle 108 relative to the spindle support structure 110 via the adjustable stop 132 promotes the ability to adjust the blanket spindle 108 between the position parallel to the ground to a position substantially inclined at a 20° angle to the ground.
FIG. 4 further shows the rotary hub assembly 114 is secured to the spindle support structure 110 by a rotary hub axle 134 (showed in dashed lines), which interacts with a rotary hub bushing 136 to promote vertical rotation of the rotary hub assembly 114 relative to the spindle support structure 110. Preferably, the rotary hub bushing 136 is presented with a square external configuration to promote ease of welding the rotary hub bushing 136 to the spindle support structure 110.
In a preferred embodiment, the adjustable stop 132 is secured to a first horizontal support brace 138, which together with a second horizontal support brace 140, establish a predetermined distance between the first side wall 142 of the rotary hub assembly 114, and the second side wall 144 of the rotary hub assembly 114. Additionally shown by FIG. 4, the first horizontal support brace 138 supports a casing 146, the casing 146 houses a bearing 148, which interacts with a rotatable shaft 150, which is free to rotate relative to the casing 146.
