Be it known that I, RICHARD F. KREITER,

i a citizen lof the United States, residing at Houston", in the county of Harris and State of Texas, havel invented new and useful lm provements in Pumps, of which. the following a specification. i

My invention relates to new and useful larly to pneumatic pumps.

The object of the invention is to provide a device of' this character which may be attached to 'an automobile and which will efectually fill the space desired to be filled with compressed air, such as pneumatic tires.

Another object of the-invention is to provide a device ofthis character which may .he mechanically operated.

lwherein Afurther feature resides in the provision of means whereby the device may be so adapted as to fit on and be operated by an automobile.

` A still further feature resides in the provision' of means whereby the machinery contained in said pump will be constantly oiled While the machinery is in operation and one in which all the parts where wear may occur -will be protected from'dust, grit and other foreignsub'stances.

'Finally the object of the lnventlon is to provide a device of the character' described Fig-ure 1 is a sectional side -view 'showing the lower end of connecting' rodl broken away.v Fig.' -2 is a sectional view taken on the line A. B. of Fig. 1. Fig.- 3 is an elevation of the pump complete 'showing one method of attachment to an automobile and method of providing same.` Fig. 4 isv a partial sectional end view of the pump having the same means of attachment as in Fi g. f

3 and showing a-segment of the fly wheel. .Y

Referring more particularly to'. the drawings, wherein'like numerals 'of .reference 'res -fer to corresponding parts 'in all drawings, the numeral 1 designates the upper portion der on the crank shaft.-

accompanying drawi11gs,

of the outer casing of my air compressor and l designates the lower section thereof. These sections are secured together' in such a manner as to exclude all dust and other foreign substances. l

2 refers to the casing of the friction wheel which .operates the air pump. 3 refers to the packing of said friction wheel and is made, preferably, of compressed paper.-

This packing ts in an annular groove .ft provided on the circumference of sald wheel. This wheel is also provided with -a central hub for the purpose of receiving a shaft 2G and i's held rigidly on said shaft by means of fa pin 29, set screws or other suitable means.

The aforesaid ailing is erst puc on uw wheel while it is in uniinished condition and then the cap 5 is screwed onto 2 which com-1 pletes the wheel'. There are various methods by which this wheel may be held against` turning on the shaft. My preferred method is as follows: The outward end of the 'hub iss-provided with two diametrically opposing depressions, having theirv correspending sides gradually sloped to intermedia-te high points 33 in the hub. The pin 29 passes through a hole in the shaft and lits snugly in these depressions' which are so shaped that when the wheel starts to turn on shaft 26 the sloping ysides of these depressions pass lunder the pin and gradually tighten the wheel by forcing it back against a shoul- This keeps the wheel always rigid with the shaft while in motion and prevent-s the usual wear andV play of the wheel.

7.. lrefers to a valve stem which projects through the casing 1 and is attached to valve 8 at its lower end and is held in normal position by spring 9. Plug 10 engages the wall of casing l at 11- and carries a spring 12 which holds valve 13 normally against seat 14; i v i y Connecting ,-rod 15 is attached at one end.A to a piston 16 by means of pin 17 and atA its other Vend is rotatably connected to wrist pi 18. One'end of shaft 26 is coveredby. cap shaped boxing 19 which is screwed or bo ted to the main casing andi'sso censtructedthat ifit is desired for any reason to reverse the friction whl shaft and lace i the friction wheel .upon the other si' e.

the pump, this may he readilyy .done asthisf boxing andy its'opposing boxing 28 .will-et' on'either side'of thevpump. These boxigs are so, 'snugly'.titted into the ,casing as to ex! clude all dust and foreign matter not only from' the bearings but also from the inside 0fthe casing. A groove 20 runs along the boxing mi. air outletinto the tube which upper portion of the boxing cap 19 and the 28 along which oil is fed through 4openings 21 for thepurpose of lubricating the bearings. Opening 22 is an air inlet to air chamber 27, while opening 23 is au leads to the 24 designates points of attaclnnent Jfor ati taching my device to any automobile and 25 i designates points to which suitable means '32 for manually pressing friction wheel 2,

against fly wheel 31 of the automobile may be attached.

6 designates a cup shaped device which is intended for the purpose of throwing oil up overthe -various parts while the crank shaft is in motion.

Y The operation of my device is as follows:

The inlater is first attached to some conven- I' `ient part of the automobile near enough to allow `the friction wheel 2 to come in contact with the i'iy wheel 31 of the automobile, which sets in motionthe drive shaft 26 and causes connecting rod 15 to rise and fall.

Thisconnecting rod being so connected to piston 16 raises and lowers said piston.

Whenpiston 16 is lowered it causes a partial vacuum to be formed and the air presses vvalve 8 downwardly admitting air through ppening22into air chamber 27. When the piston reaches its lowermost point the pressure of the air is relieved on valve 8 which vspringQ-lifts back to its original position by aid of the air which is now being compressed by the movement of piston "16. Thiscuts oli" the possible escape of air in this direction but when the air in chamber 27 is suiliciently compressed it lifts valve 13 and a1- llows the air to escape throughopening 23 to which may be attached a tube leading to the tirel of the automobile. This movement of the-piston may berepeated until the tire is suiliciently inflated. Special attention is called to thel method of oiling also the fact that shaft 26 `may be reversed and thereby allow 'the air` compressor placed on either side of the fly wheel of the automobile thus making my device adjustable to any style of automobile. Also special attention is called Aeo able point and'has its other end cylindrical. This end passes through hole 24y on one side of the pump and the latter is secured .thereon by a Cotter pin 35 or some similar means. The pump is thus held pivotally attached to the machine and the friction wheel 2*. is n ormally held from the ily wheel of the engineA by means of the spring 34 which passes through a hole in the clamp 37 andI around the boss 36 at its other end. To put the pump in operation pressure is exerted against rod 32 in the direction of the fly wheel which forces the. friction or drive wheel 2 against the fly wheel 31 of the automobile. lhe friction wheel is held against the iiy wheel untilv a suilicient amount of pressure is had in the automobile tire when pressure is released upon rod 32 allowing the pump to be drawn away from the fiy wheel by means of spring 34 to its normal position.

Another method of attaching my inflater to the automobile is shown in Figs. 1 and 2 wherein the numerals 38 designatey ears which are .provided with square holes. The clamp 37 is .provided at its free end with a squared shank which fits in said hole, thus making the inflater slidable upon said shank.. l spring 39 forces the inflater away from the ily' wheel and a hand wheel 40 which screws over a threaded end 41 of the squared shank forces the Vinlater toward the Hyv wheel.4 The intlater can also be belt driven or chain driven or gear driven in which'case vit should be rightly-fastened to the motor. These methods of driving the inllater would bev necessary on machines .where the fly wheels are not readily accessible and some other part of the motor. is used as a driving means.

Vhat I claim is 1. vIn a pump of the character described, the combination withV a easing and the operative means, as described, carried thereby, of laterally extending lugs, carried by the said casing provided with openings extending therethrough, means for attaching said pump'to a stpgionary body, thefree end of said means being so shaped as `to fit into said openings, means for forcing said pump out of its normal relation to said stationary body, and means for restoring said normal relation. l

2. lIn a pump, a casing comprising a cylirr der and a crank chamber, a crank shaft extending through -said chamber, reversible bearings in which said shaft operates, longitudinal grooves in said bearings, a drive wheel carried by said shaft, inlet and outlet passages to said cylinder, valves for cony trolling the same, a piston in said cylinder,

means for imparting motion from said crank shaft to said piston, laterally extending lugs carried by the said casing provided with openings extending therethrough, means for attaching said pump to a stationary body, thefree end of said means being so shaped `as to fit into said openings, means for forcing said pump out of its normal relation to said stationary body, and means for restoring .said normal-relation.

3. In a pump as described, the combination `with a casing, of a piston to operate in the-cylinder thereon, inlet and outlet passag leading to said cylinder, means for operatin said piston, laterally extending lugs carrie by said casing provided with openings extending therethrough, means for attaching said pump to a Stationary body, the free end of said means being so shaped as to t into either of said openings, a driving member, means for normally releasing `the operative means of said pump from contact with 'the driving member, and means for forcing the operative means of said pump into contact with the driving member. 4. Ina pump as described, the combination with acasing and a cylinder carried thereby of a piston to operate in said cylinder, inlet and outlet passages leading to said cylinder means for operating said piston, laterally extending' lugs integral With said casing, a non-cyl1ndrical hole extending througheach of said lugs, means for attaching said pump to a stationary body, an intermediate portion of which is so shaped as to fit in said hole and the free end of which is provided with means for forcing said pump lout of its normal relation to said Stationary body, means for restoring said normal relation,

In testimony whereof I have signed my name to this specification in the presence of' tivo subscribing Witnesses.
