As noted, the padlock 152 is configured for connection to the angled bracket 140 via insertion of the second end of the shackle portion 154 through the opening 150 in the second portion 150 of the angled bracket 140 and locking the second end of the shackle portion 154 to the body in the locked position, which is shown in FIGS. 7-9. In embodiments, when locked, the padlock 152 is positioned in substantially parallel configuration relative to the first portion 144 and/or the surface of the locomotive to which the anti-theft device 108 is attached. The padlock 152 includes a body with an arm or a shackle portion 154. The shackle portion 154 has one end connected to the body and a second end removably connected to the body for moving between locked and unlocked positions. The body of padlock 152 has a locking mechanism therein (not shown) and is configured for receipt of a key or a disassembly tool through its (key) entry or receipt portion 156 to lock and/or unlock the shackle portion 154. In one embodiment, the locking mechanism in the padlock 152 is a pin and tumbler construction. It may or may not have an optional locking cam. As shown in FIG. 9, the receipt portion 156 may be provided in a bottom of the body of padlock 152. It can alternatively be provided on a side or top or bottom surface. In another embodiment, in addition to or instead of receipt portion 156, a locking combination can be provided.
The shackle portion 154 of padlock 156 may be made of hardened steel, for example, to prevent cutting or snapping thereof, and thus removal of the padlock 152 from the angled bracket 140. Other material(s) can alternatively or also be used to form at least the shackle portion 154. To further reduce access to the attachment fastener 136 and limit slack of the padlock 152, bushing 142 is provided on shackle portion 154 of padlock 152 when attached to angled bracket 140. As shown in FIG. 5, the bushing 142 has a through hole for receipt of the shackle portion 154 of the padlock 152 therethrough. The bushing 142 is configured for placement on the shackle portion 154 and placed substantially over the attachment fastener 136. The bushing 142 protects the attachment fastener 136 from being accessed. Accordingly, when installed, such as shown in FIGS. 7-9, the anti-theft device 108 is configured to at least partially cover the attachment fastener 136 attaching the first portion 144 of the angled bracket 140 to the horn 110 such that access to and/or removal of at least the attachment fastener 136 is substantially prevented. The bushing 142 is also configured to substantially reduce, limit, and/or eliminate any slack, leeway, or give of the padlock 152 relative to the angled bracket 140 when the second end of the shackle portion 154 is locked in position to the body (e.g., see FIG. 8). The shackle portion 154 is received in opening 150 and curved recessed portion 158 of the angled bracket 140.
The bushing 142 can be formed from materials that are tough to cut through. For example, in an embodiment, the bushing 142 can be formed using hardened steel.
Alternatively, in embodiments, the bushing 142 can be built into the padlock (e.g., on the shackle portion). In accordance with embodiments, the padlock 152 can be an armored padlock with a built in bushing 142.
To assemble and install the anti-theft device 108, the angled (or L-shaped) bracket 140 is attached to the mounting portion 112 of the horn 110 by aligning the opening 148 of the first portion 144 of the bracket 140 with the opening in the mounting portion 122. The opening in the mounting portion 122 is aligned with an opening in the surface of the locomotive, for example. A washer (i.e., its opening) 132 is optionally aligned with the openings. A threaded portion and/or shank of the attachment fastener 136 is inserted through the aligned openings of the (optional) washer 132, opening 148 of the second portion 144, and opening in the mounting portion 122, as well as the opening in the surface of the locomotive. The attachment fastener 136 is secured by a nut 134 on an end of its threaded portion. The bushing 142 is slipped on the shackle portion 154 of the padlock and the second end of the shackle portion 154 of the padlock 152 is placed through the opening 150 in the extended second portion 146 of bracket 140. The first end is aligned in the curved recessed portion 158 of the second portion 146. The second end of the shackle portion is locked with the body of the padlock, thus blocking access to the attachment fastener 136. Accordingly, the installed combination of an L-bracket or angled bracket 140, padlock 152, and bushing 142 as the anti-theft device 108 on the locomotive horn 110 substantially shields and prevents removal of and denies access to the attachment fastener 136 (e.g., the anti-theft bolt), as shown in FIGS. 7-9. Since access to at least the attachment fastener 136 of the horn 110 attached to the locomotive is prevented, any tool or other device cannot be used to remove the attachment fastener 136.
The herein disclosed anti-theft device 108 can be applied to any locomotive horn without any welding, additional fasteners, etc. required. Besides limiting access to the attachment fastener 136, it also facilitates key-only access (e.g., to padlock 152 as well as to attachment fastener 136) for replacement of the horn 110. It acts as a deterrent to thieves who may grind or attempt removal of bolts and/or welds, and improves security against theft.
Also, the herein described padlock can be a lock that is standard issue in the railroad industry. Accordingly, costs for implementing the disclosed anti-theft device can remain low.
While the principles of the disclosure have been made clear in the illustrative embodiments set forth above, it will be apparent to those skilled in the art that various modifications may be made to the structure, arrangement, proportion, elements, materials, and components used in the practice of the disclosure.
It will thus be seen that the features of this disclosure have been fully and effectively accomplished. It will be realized, however, that the foregoing preferred specific embodiments have been shown and described for the purpose of illustrating the functional and structural principles of this disclosure and are subject to change without departure from such principles. Therefore, this disclosure includes all modifications encompassed within the spirit and scope of the following claims.
