Abstract
According to various aspects, exemplary embodiments are disclosed herein of audible alert systems. In exemplary embodiments, an audible alert system includes a speaker, an audio amplifier, and an audio file player. The audio amplifier and audio file player may be housed within an environmentally sealed enclosure, which provides protection from the environment. The audible alert system may be located on the front or back of a locomotive. For example, the speaker may be mounted to handrailing of the locomotive.
Claims20
A system comprising:
- an audible alert system for a locomotive including a speaker, an audio amplifier, an audio file player, and an enclosure, wherein the audio amplifier and the audio file player are within the enclosure;
- an assembly mountable to handrailing of the locomotive and the audible alert system, wherein the speaker of the audible alert system is mountable to the assembly, such that the speaker of the audible alert system is mountable via the assembly to the handrailing of the locomotive;
- and
- a speaker bracket positionable generally between the speaker and a portion of the assembly, and wherein:
- the speaker bracket includes fastener holes alignable with corresponding fastener holes of the portion of the assembly, whereby one or more mechanical fasteners are insertable through the aligned fastener holes of the speaker bracket and the portion of the assembly to thereby couple the speaker bracket to the portion of the assembly;
- and/or
- the speaker bracket includes fastener holes alignable with corresponding fastener holes of the speaker, whereby one or more mechanical fasteners are insertable through the aligned fastener holes of the speaker bracket and the speaker to thereby couple the speaker bracket to the speaker.

A system comprising:
- an audible alert system for a locomotive including a speaker, an audio amplifier, an audio file player, and an enclosure, wherein the audio amplifier and the audio file player are within the enclosure;
- and
- an assembly mountable to handrailing of the locomotive and the audible alert system, wherein the speaker of the audible alert system is mountable to the assembly, such that the speaker of the audible alert system is mountable via the assembly to the handrailing of the locomotive;
- wherein the assembly comprises an upper horizontal arm and first and second hooks configured to be hooked over and onto the locomotive handrailing, the first and second hooks slidably coupled to the upper horizontal arm, whereby the first and second hooks are horizontally slidable relative to each other along an upper surface of the upper horizontal arm to thereby allow adjustment to a distance separating the first and second hooks.

A system comprising:
- an audible alert system for a locomotive including a speaker, an audio amplifier, an audio file player, and an enclosure, wherein the audio amplifier and the audio file player are within the enclosure;
- and
- an assembly mountable to handrailing of the locomotive and the audible alert system, wherein the speaker of the audible alert system is mountable to the assembly, such that the speaker of the audible alert system is mountable via the assembly to the handrailing of the locomotive;
- wherein the assembly comprises:
- an upper horizontal arm including opposing upper and lower surfaces;
- a lower horizontal arm including opposing upper and lower surfaces;
- an upper vertical arm slidably coupled to the upper and lower horizontal arms, whereby the upper vertical arm is horizontally slidable along the lower surface of the upper horizontal arm and the upper surface of the lower horizontal arm;
- and
- a lower vertical arm slidably coupled to the lower horizontal arm, whereby the lower vertical arm is horizontally slidable along the lower surface of the lower horizontal arm.
6 more elements
A method comprising:
- providing an audible alert system onboard a locomotive, the audible alert system comprising a speaker, an audio amplifier, an audio file player, and an enclosure, wherein the audio amplifier and the audio file player are within the enclosure;
- and
- mounting the speaker of the audible alert system to handrailing of the locomotive via an assembly and a speaker bracket positioned generally between the speaker and a portion of the assembly;
- wherein:
- the speaker bracket includes fastener holes alignable with corresponding fastener holes of the portion of the assembly, whereby one or more mechanical fasteners are inserted through the aligned fastener holes of the speaker bracket and the portion of the assembly to thereby couple the speaker bracket to the portion of the assembly;
- and/or
- the speaker bracket includes fastener holes alignable with corresponding fastener holes of the speaker, whereby one or more mechanical fasteners are inserted through the aligned fastener holes of the speaker bracket and the speaker to thereby couple the speaker bracket to the speaker.
