Description
- The present invention relates generally to art of fluid sprinkling and more particularly to the art of snow making and improved apparatus for installing and supporting a snow tower.
- The present invention pertains particularly to a support system for snow making towers which incorporate an upright elongated tower conduit, usually at least 20 feet long and having air and water supply connections at its bottom end and at least one fluid discharge nozzle at the upper end for making snow in freezing ambient conditions. A problem encountered with present day support systems for such towers is that it is difficult to install and uninstall a tower on its ground support, particularly in freezing winter conditions. Also, it normally takes more than one attendant to install and uninstall the tower conduit. In addition to providing a mounting system wherein the tower conduit can be easily raised, it is also desirable to have a mounting system which further permits the tower to be rotated axially through a considerable range and then be fixed at a desired angle of rotation.
- The snow making tower of the present invention is comprised of an upright elongated tower conduit member which generally has two or more conduit channels therein and therealong for the passage therethrough of air or water or a mixture thereof. An example of such a tower conduit is illustrated in U.S. Pat. Nos. 5,823,427 and 6,543,699. This elongated conduit member is provided with air and water supply connections at its bottom end and is further provided with at least one fluid discharge nozzle at the upper end for discharging air or water or a mixture thereof in freezing ambient conditions for making snow. The elongated conduit member is supported from an upright support pole which has a bottom end thereof anchored into a ground surface.
- The tower mount of the present invention includes spaced upper and lower tower supports protruding in the same direction from a side of the support pole for supporting the tower conduit member. The upper support includes a hoop which laterally extends from the pole and has a minimum inner diameter which is sufficient whereby the tower conduit member may be readily slid upwardly through the hoop with clearance, even though the conduit member may have multiple bends and protruding nozzles at the upper end thereof. The lower support is comprised of a support arm which laterally extends from the pole and supports the conduit member for axially rotation thereon. The lower support is comprised of an upturned L-bracket protruding from the support pole and a downturned L-pipe protruding from the conduit member and which further has the downturned portion thereof coaxially received over the upturned portion of the L-bracket for axial rotation of the downturned pipe portion on the upturned bracket portion. This permits supported rotation of the tower conduit member about the lower bracket axial rotation connection for almost a full 360°. A stop mechanism is provided for selectively preventing further axial rotation of the downturned pipe portion of the lower support relative to the upturned bracket portion thereof to fix the angle of rotation as desired.
- Additionally a detent mechanism is provided in the lower support for selectively retaining the downturned pipe portion at a desired position of axially rotation relative to the upturned bracket portion without or prior to engaging the aforedescribed stop mechanism. Also, it is preferable that the hoop for the upper support is connected to the support pole with a pivotal connection whereby the hoop is permitted to pivot about a horizontal axis. This permits rotation of the hoop as the elongated tower conduit member with multiple bends is being slid upwardly through the hoop by the attendant for mounting on the pole and it further permits rotation of the hoop as the tower conduit member is being rotated axially on the lower support.
- The upright support pole may be any preexisting support pole. For example, the support pole might consist of a wooden pole, such as a wooden telephone pole. Some existing tower supports have the tower supported on an arm that rotates in a vertical plane on the top of the support pole. For example, see U.S. Pat. No. 6,152,380. Such a preexisting support pole may be utilized for the mount of the present invention by positioning the support arm to vertical and then attaching the mount of the present invention thereto. In another embodiment of the present invention, the support pole may include a support pipe slidably received over the ground support pole for axial rotation thereon and the upper and lower supports are secured to this support pipe. This permits 360° rotations of the supports.
- Air and water hydrants protrude from the ground surface adjacent the support pole with hoses respectively connecting the hydrants to air and water supply connections at the bottom of the tower conduit member whereby the hoses have no portions which sag to form a water trap. This permits full rotation of the tower yet also prevents any accumulation of water within the hoses which may freeze when the tower is turned off. Also, it is desirable to insulate all exposed portions of the air hydrant, air hose and air supply connection in order to prevent freezeup of the moisture within the air line.
- The result of the present invention is that a single installation person can easily mount the light weight aluminum tower conduit member to the support of the present invention without assistance, even in severely cold weather. The attendant accomplishes this first of all, because the elongated tower conduit member is preferably constructed of lightweight aluminum and secondly, the attendant permits the bottom end of the tower conduit member to drag on the ground surface and inserts the upper end of the tower conduit member through the upper support hoop. The attendant then continuously feeds the tower conduit member upwardly through the hoop of the upper support, dragging the bottom end of the conduit member along the ground until the final stages. At this point the attendant lifts the bottom end of the tower upwardly further feeding the tower member through the hoop and then drops the downturned L-pipe protruding from the conduit member down over the upturned L-bracket protruding from the support pole. The attendant then rotates the tower conduit member to the desired attitude and then locks the downturned L-pipe to the upturned L-bracket.
- Other objects and advantages appear hereinafter in the following description and claims.
