A wildland firefighter is a valuable resource to protecting public lands and managing fuels. The many hand tools used by firefighters aid in their ability to complete any required tasks effectively. Several of the tools available are specially purposed for individually grubbing, scraping, or liming. A small squad of firefighters could become a more effective resource if the tools they carried could perform several of these purposes as one single tool. To improve the effectiveness of an individual on the fireline a multi-use hand tool was designed to include an axe for liming and a heavy duty scraper for grubbing …

Jeep Wj Multipurpose Oversize Spare Tire Carrier, Caleb J. Marrs

All Undergraduate Projects

OEM spare-tire wells have size limitations that only allow up to a certain size tire. However, the OEM tire well is not effective for the off-road enthusiast that needs an extra over size tire in case of an emergency. While off-roading it is important to be equipped with all the necessary tools and parts to get out safely because there is no roadside assistance off-road. The Jeep WJ is not a popular off road vehicle which means aftermarket accessories are not common. In order to optimize the space inside and out of the vehicle, a device is needed that will …

Paper Core Feeder System, Sergio Flores Velez

This production line has a three part system that automatically feeds the paper cores to the spool shafts to roll the films. Therefore, the employees during that shift do not have to worry about filling up the bin very often. On the other hand, the second production line, which produces the hand films, does not have …

Shellfish Bag Maker, Trevor R. Reher

All Undergraduate Projects

When commercially harvesting shellfish specifically clams and oyster, plastic mesh bags are commonly used to place shellfish in after harvesting on beaches. The issues is taking the raw bag material used for harvest and cutting it to a specified length. The material comes on a 2000 ft. spool and needs to be cut to a length of 54 in. Using an existing but out dated machine, a bench mark was made that the new design must be 10% more efficient for the customer to invest money into building the machine. Using mechanical machine design and computer designing software the machine …

The Design And Construction Of A Torque Measuring Arm For An Air Motor, Logan Dearinger

All Undergraduate Projects

There is a system efficiency lab that sits in the thermodynamics lab of the Mechanical Engineering Technologies department. To expand this lab, a torque measuring device was needed to measure the torsional force that the pump exerts on the air motor. The expansion of this lab is important to give a better understanding of how the different mechanical parts effect the efficiency of the overall system. The first step in the expansion process was the design of a suitable torque measuring device. The most efficient design was a simple one with minimal moving parts. When the air motor is energized …

Flag Raising Device, Josh Quintero

All Undergraduate Projects

The motivation for this project stems from a lifetime of boating with father Richard Jones. One problem that many people encounter, including Richard, was when towing someone behind a boat, is the difficulty with handling the warning flag. This flag is used to show other surrounding boats that someone has fallen into the water behind their boat. This warns other boats to stay far away from that area to keep safe from running over the swimmer. Although, when holding the flag in the boat, it can be hard to see at times. The boat driver, or other people standing in …

The Pneumatic Leg Extension, David G. Sedano

All Undergraduate Projects

In recent years, reaching altitudes that are higher than your normal-height has evolved from pure amusement to an “in-demand” necessity out in the field. Means of achieving greater than normal height range from wooden poles to aluminum stilts. The era of ladders and other extension methods are slowly fading away. There are many designs in the market that focus on different factors to make a stilt. As other designs focus on one or two enhancements, the pneumatic leg extension’s objective is to improve all aspects of the stilt. This radical new design differs greatly from traditional stilt designs. The pneumatic …
