I found a URL containing an interesting set of tidbits on the US Patent 276,441 referenced in the Dead Media Working Note 21.1:

http://www.inventors.about.com/science/inventors/library/inventors/blpneumatic.htm

It seems that these early pneumatic devices had "wheels, on a track, positioned within a tube."

I know hindsight is 20/20, and it now makes sense to not have the added complication of wheels attached when sending something through a tube. The URL mentions quite a few inventions that progress through time. I can see why he would have called them "little cars."
