Sibley tent

The Sibley design also required no guy ropes, being held down by twenty-four pegs around the base.

[1][3] Additionally, unlike earlier designs, the use of a cowl over the central pole allowed for ventilation and for the escape of smoke, regardless of wind direction.

The US Army used the tent exclusively during the Utah Expedition during the winter of 1857–58, proving the design.

[6][7] In accordance with an 1858 agreement with the Department of War, Sibley would receive US$5 for every tent made.

After Sibley's death, his relatives attempted unsuccessfully to collect the royalties from the War Department.
