The present disclosure relates to the field of transfer systems for conveying dry materials. More particularly, for food and beverage pipe bonding mechanical jumper kits.
In the food and beverage manufacturing process, pipes or conduits form part of the distribution system that is used to convey dry or liquid materials from a source to a destination. For sanitation purposes, these pipes are typically made of metal and may also be electrically conductive. Consequently, the friction caused by the material passing through the interior channel of the pipe can result in an electrical potential buildup at the pipe. Without proper electrical grounding protection, the electrical potential can discharge, thereby causing the material, such as flour, traveling through the metal pipe to ignite or combust. To prevent such occurrences, the elongate articles used in the food and beverage industry and other similar applications typically utilize grounding protection devices that are welded onto the metal pipe. Improved electrical grounding protection devices are desirable.

As material passes through the channel of an elongate article (e.g, metal pipe), the resulting friction may cause a buildup of an electrical discharge potential in the form of electric current at the elongate article. Without adequate grounding protection, the material passing through the elongate article can ignite or combust due to the discharge of the electrical potential, thereby potentially damaging equipment and/or causing injury to personnel. Conventional grounding methods include welding a stud onto an exterior surface of the elongate article and bolting a conductor (e.g., jumper, bonded jumper, etc.) onto the stud. However, this approach requires using specialized tools and equipment (e.g., welding tools) to weld the stud onto the pipe and also requires specialized permits to perform such work (e.g., hot work permits). As used herein, the term “pipe” refers to an elongated cylindrical conduit having one or more enclosed channels extending through the conduit and used for conveying material, such as a dry flowable material, from a source reservoir.
The present disclosure includes various embodiments of a device, apparatus, system, or kit that includes one or more components adapted for mechanically and electrically connecting to an electrically conductive elongate article. The article is a metal pipe. In some embodiments, the article may include a conduit, channel, or other elongate electrically conductive article used to convey materials through the article. Additionally, the device connects the article to one or more grounded electrical conductors, thereby providing grounding protection to the article. The device is adapted to flexibly extend around the article such that the article extends through a central cylindrical opening formed by the device and the device securely attaches to the article by applying a tension force onto the article extending through the opening. The device is also adapted to be installed onto the elongate article using only hand tools. For example, with a hex wrench or other driver tool. Accordingly, the device may be easily installed onto the article to provide electrical grounding protection without requiring welding tools or requiring permits to install the device onto the article. It is to be understood by those of ordinary skill in the art that the article may include any of a plurality of diameters and profiles suitable for conveying dry materials through an interior channel of the elongate article. Accordingly, it is also to be understood by those of ordinary skill in the art that the device as described herein in not intended to be limiting any may include any of a plurality of dimensions suitable for being installed onto the article to provide electrical grounding capabilities to the article.
In various embodiments, the device may be made substantially out of metallic materials suitable for providing grounding protection to the article by providing a discharge path for an electrical discharge potential that may build up at the article. In various embodiments, the device may be formed of metallic materials that are also corrosion resistant to prevent the buildup of rust on the device. For example, the device may be subject to a chemical washdown due to cleaning or sanitization procedures in the food manufacturing process where a chlorine bleach solution is applied to the device. In some embodiments, the device may be made of steel. In other embodiments, the device may be made of stainless steel. In some embodiments, the device may also include non-metallic materials.

Furthermore, a clamping force may then be applied to the first nut 128 to attach the first nut 128 to the strap member 102 at the first aperture 114. The clamping force mechanically deforms the first nut 128 in the first aperture 114, thereby mechanically binding the first nut 128 to the strap member 102 through mechanical deformation, thereby restricting movement of the first nut 128 relative to the strap member 102 in an axial and radial direction.

The set screw member 126 engages the tensioning member 120 by threading into the bore 140 and extending into the channel of bore 142. Bore 142 is also adapted to receive an electrical conductor in bore 142. In some embodiments, the electrical conductor can be inserted into bore 142 such that the electrical conductor extends past the opening to bore 140 in bore 142. Accordingly, in some embodiments, the set screw member 126 may be threaded into the bore 140 to drive the set screw member 126 into the bore 142 and to enable the set screw member 126 to impinge on the electrical conductor positioned in bore 142.

The tensioning member 120 extends through the first nut 128 by engaging the threads of the first nut 128. Additionally, the position of the tensioning member 120 relative to the first nut 128 may be adjustable in the direction a by rotating the tensioning member 120 clockwise or counterclockwise relative to the first nut 128. Therefore, by adjusting the position of the tensioning member 120, the tensioning member 120 can extend from the first nut 128 to contact the elongate article and to apply the tension force between the strap member 102 and the elongate article. In some embodiments, the bore of the first nut 128 may be referred to as a third bore.
The tensioning member 120 is adapted to extend through the first aperture 114 and the second aperture 116 of the strap member 102 and through a first nut 128. Accordingly, the threads of the cylindrical portion 138 engage the threads at the bore 130 of the first nut 128 to enable the tensioning member 120 to extend through the first nut 128. Additionally, the head portion 136 acts upon the first flange 108 and the second flange 110 as the tensioning member 120 is threaded through the first nut 128 so that a compressive force is applied between the head portion 136 and the first nut 128 to retain a position of the strap member 102 between the tensioning member 120 and the first nut 128. The tensioning member 120 is also adapted to extend through the first nut 128 to contact a metal surface of the article to place the article in connection with a conductor connected to the tensioning member 120. Accordingly, the tensioning member 120 is also adapted to electrically connect the article to the electrical conductor to provide a discharge path for electrical current from the article to the grounded electrical conductor through the tensioning member 120.
The position of the tensioning member 120 relative to the first nut 128 may be adjustable in the direction a substantially perpendicular to a central longitudinal axis of the article. Additionally, the position of the tensioning member 120 relative to the first nut 128 and the article may be adjusted in the direction a by rotating the tensioning member 120 in the clockwise or counterclockwise direction in the threads of the first nut 128. The position of the tensioning member 120 relative to the first nut 128 may be adjusted to enable the tensioning member 120 to adjustably extend towards the article until the second end 124 of the tensioning member 120 contacts a surface of the article. Additionally, the position of the tensioning member 120 in the direction a may also be adjusted to apply a tension force onto the article and the strap member 102. Applying the tension force on the strap member 102 and the article extending therethrough facilitates connected engagement between the tensioning member 120 and the surface of the article and also facilitates retention of the device on the article.
In various embodiments, the position of the device 100 relative to the central longitudinal axis of the article may be retained by the tensioning applied by the tensioning member 120 onto the article and the strap member 102, where movement of the device 100 is thereby restricted along the longitudinal axis of the article.
