duty concern:

Be it known that I, GEORGE W. KELLOGG a resident of Rochester, in the-county of Monroe and State .of New York, have in vented certain ments in Detach Lew and useful Improve- 2. le Pumps; and I do hereby declare the follovt'in' to be a full, clear, and

0 the invention, such" as will enable otheri skilled in the art to which it ertains to male and use the same.

he' inventiongrelates to power' driven r m ating pne'imatic tires, but adapted e i also for otherus p The objjct of tie invention is to provide sim le an efficient means whereby a pump. wit its .gearing, ifnd suitable; for'such use,

y a lily setured temporarily and at will to an exterior driving pinionsecured to a suitable powerjdriven shaft in conven 'ient situation for} connecting the pump theretoand disconntcting it therefrom.

The invention corsists in theconstruction here'nafter'described and particularly point ed out. v

' In the accompanyirlg drawing whichillustrates the invention and forms part of the specification,Figures 1 and 2 are respect1vely. an elevation and an end View of'the ing mechanism of the pump, an an exten-' slon part 2 adapted tofit over a pinion 3,

the latter not forming a permanent part of' the pum but being secured to any suitable driven s aft- 4, which may be, for example, an engine or motor drivenshaft on an automobile. Pinion 3 is preferably made in two parts, with securing means for easily connecting the pinign to its shaft. The hub 5 of this pinion is large, and projects on both sides of the gear teeth, as shown most clearly in Fig. 4, w ich shows the lower half of the pinion and. 1 hub. Part 2 of the body is adapted to fit ovr pinion 3, and-t0 partly enclrcle hub 5on both sides of the circle of teeth. I I 1 'Pivoted to-bodylat 6 is a strong movable jaw also adapted to fit over and partly surround the pinion if and its hub. Both part 2 and'jaw 7 have agroove 8 loosely receiving 7 nn racnannu 954',se4./

Each part 26 has a threaded end 28,.to either of which. a hose may be conders to a tire or the ke. The hose will be connected to one part/'28 or theotheraccording' to 'convenience, for example,-it may de-.v pend on which side of an automobile the pinion 8 is secured.

Having thus descrlbed the invention what I claim is, 1. In a device of the character erating'gearing-carried by said body, said the same from c.

The pump can be attached to pinion 3, or I detached-therefrom in a moment, and in such eflicient manner that the pmion, and wheel 13 are held in cooperating relation as though they were both (and not wheel 13 only) permanent parts of the pump mechanism.

The invention is not confined to all the details of construction set forth as they may be varied within the principle of the in;-

/ described, a' supporting body, a pump comprising opbody having an extension, a movable pivoted part cooperatin with 'the extension, said extension and sai -inovablepart being adapted to rotatably hold the pumpgearing in cooperating relation with an exteriordriving pinion. J r
