" AIR-PUMP. p

Tov all whom it may concern: v

Be it known that I, PAUL E. KLEINEBERG, a citizen of the United States, and a resident of Croton Falls, in the county of Westchester --and State of New York, have invented certain new and. useful Improvements in Air- Pumps, of which the following is a specification., l i

The invention relates to improvements in` air-pumps..foninflatingtires and other pur poses; vanduit consists in the novel features, construction, arrangement, and combinations of parts hereinafter described, and particularly pointed out inthe claims..

The object of the inventien is to rovide passes to the space within the outer tube below the piston, and during the downstroke of the inner tube the air below said l piston is compressed and forced into an annular chamber between the inner and outer tubes andwhich connects with,v the tire to be inflated. Upon'thesucceeding upstroke its upper end and, receives, an externallythreaded dependin hollow hub 21 formed of the inner-tube airis again admitted to the space within the lower end/of the outer tube.

and the air which was partly compressed on the preceding downstroke andentered the annular chamber between the tubes becomes furthe r compressed and forced along to the tire.

Thus during eachupstroke of the innertube additional airis suppliedl to the .chamber and duringeach downstroke of the inner tube the fresh air admitted during the upstroke thereof is placed under compression and forced intov the said annular space between `the tubes pre aratory to being further compressed upon t e succeeding upstroke 4of the inner tube. A.

The-invention willv be fully understood from the detailed description hereinafter pre- Specification ofLetters Patent.

.said base'being preferably in one integral casting and, of elongated outline and having at its centeran internally-threaded vertical hub 20, receiving' and engaging la screwthread on the lowerendof said outer tube.

The inner tube 2 is internally threadedat integrally with the and-le 3, whic h is preferably inthe form of lan integral casting; of elongated outline, comprising a vertical web portion 22 and transversel anges 23 atgthe i edges thereof, said handle thus being of. I-y shape in cross-section and while possessing the requisite strength is of minimum Weight and capable of being economically ymanuff'actured. The hub 21 is formed at the center of -the lower .edge of the handle 3 in the formof IOO a hollow plug,whos'e upper end s'erves as a cap for the upper. end ofthe inner tube 2,

'this'cap being formed at its center with an opening 13,. whosediameter is reater than the thickness of the .web 22 as 's own in Fig. ,A
