U.S. Patent 3,243,144:  Personnel Propulsion Unit

Patented March 29, 1966
by John K. Hulbert and Wendell F. Moore, Bell Aerospace Corporation


The original "James Bond 007 Rocket Pack!"  Here are the precise and complete design engineering details for this extraordinary rocket belt, straight from its inventors. 

As the document states:  "This invention relates to the means for rendering a person airborne....  A propulsion unit for individuals ....  Only very slight movements of the shoulder-engaging component will effect significant movements of the man-machine combination.  ... in order to impart a large degree of inherent safety to the system, the operator must be permitted of a high degree of nicety in control ...."

Wow!  We want one too !

The patent goes on to say that it "... will permit the user to attain altitudes of several thousands of feet.  The hand grip assemblies provide a convenient place for the operator's hands to rest and these hand grips permit the operator to control from one control handle, in motorcycle fashion, the throttle setting of the fuel valve."

So, that's how it works. 

And there are details of construction:  "The corset assembly may be constructed principally from fiberglass reinforced epoxy material or the like ....  The control handle grip rotatably mounts a nut member having a knurled hand know portion integral therewith, the nut member being engaged with the worm or screw device in turn attached to the Bowden wire core member."  Et cetera, et cetera.

The rocket belt has (of course) a low fuel warning valve, for which we'll be thankful if we ever attain the "several thousands of feet" in altitude the inventors promise.

Actually, the patent does give comprehensive information about the invention, but isn't a "do-it-yourself-in-your-garage" set of instructions.  You'll have to work out the fine details, to say the least.  But it does provide six pages of "how it works" data, supplemented by 21 different engineering drawings.  If you're a rocket scientist, engineer, or technician, you might be able to build one yourself.

In any case, this is an unusual and exceptional reference resource for the rocket scientist, engineer, and technician--professional or "amateur."

This limited edition of the official U.S. Patent has been republished by the Rocket Science Institute.  Printed with a high-resolution laser printer (not photocopied) on high-quality, bright-white, acid-free paper and quality bound for years of reference use.  15 pages, 8-1/2" x 5-1/2" size.

NOTE:  We haven't "rekeyed" this patent.  It's printed directly from a digital version supplied to us by the U.S. Patent and Trademark Office, and while useful and fairly legible, isn't of the highest possible quality typography.  The drawings, however, are quite clear, and the information in the patent is very useful.  $9.95
