"Poised between intransigent scepticism and uncritical credulity, it [science fiction] is par excellence the literature of the open mind."
- John Brunner

Self-Propulsive Space Suit  
  A space suit outfitted with its own means of movement.  

The adventurer did not leave immediately. He thought it wise to make what preparations he could. His important weapon was the space-suit; therefore, he took it off and studied and inspected its several intricate mechanisms as well as he could in the carefully guarded light of his flash.

It was motivated, he saw, by dual sets of gravity-plates, in separate space-tight compartments. One set was located in the extremely thick soles of the heavy boots; the other rested on the top of the helmet. He saw why this was. The gravity-plates for repulsion were those in the helmet; for attraction, those in the boot-soles. This kept the wearer of the suit always in an upright, head-up position.


(From The self-propulsive suit from The Bluff of the Hawk)

The logical plan of attack had grown in Carse's mind: down and up! Down to the papers, then up and away before the men on the ranch knew what was happening: he could suppose that they, like all others on the satellite, had no knowledge of a self-propulsive space-suit. The success of his raid depended entirely on keeping the two gravity mechanisms intact. If they were destroyed, or failed to function, he would be locked to the ground in a prison of metal and fabric: clamped down, literally, by a terrific dead weight! The suit was extremely heavy, particularly the boots, and Carse learned that the wearer was able to walk in it only because a portion of the helmet's repulsive force was continually working to approximate a normal body gravity.

They had a considerable range:

Clad as they were in the latter's self-propulsive space-suits, they were quite capable of reaching Jupiter's Satellite III, only some thirty thousand miles away.

Compare to the reaction attachment from The Asteroid of Death (1931) by Neil R. Jone and the self-propelled space suit from Cavern of the Shining Pool (1937) by Leo Zagat.
