PUMP.
applicati@ inea January 25, i922. seriai no. 531,693.
To all 'whom t may concern.'
Be 1t known that I, JosnrH P. Goonrnn- Low, a citizen of the United States, residing at Blaine, in the county of Whatcom and` State of Washinoton have invented certain e) 7 l l new and useful improvements in Pumps;
and do hereby declare the following to The `objects of the invention are to provide -an air pump which may be constructed of comparatively few parts and while of small size will provide a high degree of pressure withoutgreat effort from the operator. A vfurther object is to provide an air pump with a plurality of tubes the one telescoping in action within the other, with suitable connecting valves between the chamber formed within the inner tube and a chamber formed between the .walls of the inner and outer tube and another chamber ior receiving the air from the outside.
Another object is to provide an air pump with two telescoping tubes, with connecting valves to chambers within and between'the tubes and a lock member for preventing the tubes from sliding upon each other or apart when not in use.
A still further object is to provide an air` pump with means for compressing air and forcing the same into outside spaces, with a gage connected therewith to register' the amount of pressure obtained or produced by the pumping means.
With 'these'and other objects, l have illustrated my invention with the accompanyingr drawings, in which:
Figure 1 is a vertical sectional view taken through a pump constructed in accordance with my invention;
Fig. 2 is a side elevation, and
Fig. 3 isa transverse sectional viewtaken on the line 3.-3 of Fig. 1. Y Like numerals on the different figures represent like parts, and the airchainbers are represented by letters.- Y
My pump may be of any suitable size and may be operated by any suitable power in Vmoordance with `the size of the pump, but l.
Vnormally pressed a valve 18 by sprin am illustrating my invention as in the form of a portable automobile pump :tor inating pneumatic tires, and by which the operator may without great manual eilort produce a pressure exceeding 250 pounds, and by changing the proportions of the sizes of the air chambers a higher degree oil pressure may be obtained by the saine eii'ort.
l show thc power as intended to be applied by the hands on an ordinary cross handle l, affixed by screws 2, to head piece 3, which has at its base a V-shaped valve seat et against which is normally held a corresponding valve 5 by coil spring 6. The lower part of 3 -is recessed and provided with an internal thread to receive a corresponding thread on the top end of outer barrel tube 7, a fibre washer 8 is suitably adjusted to serve as a gasket and also as a buffer to strike against the op'positely positioned collar 9 when in operation.
An inner barrel tube 10, or piston is disposed within the outer tube 7 but of smaller size than the interior of 7 so that a space or chamber F is provided between the tubes 7 and` 10. To the top portion off 1() is attached by suitable threads 11,a valve block 12 in top of which is screwed a cap plug 25, with an upper flange 26 to hold the collar 9 onto suitable cup washers 22 and 23 and gasket 24 for making tight connections when the tubes are being operated. The object of the washer 23 being` to prevent air wtrom passing downward 'from chamber C within the inner walls ot tube 7 and down outside the outer edges oi' the washer 22, during the initial compression and so preventing the washer Q2 from making a tight connection .with the same inner walls at any time.
` Theupper liace oi? plug 25 is Vdat but extends slightly above the holding and buffer collar 9 and so comes close to the base ot valve 5 when the same are pressed toward each other in action, the bottom ot 25 carries il-shaped valve seat 17 upon which is g 19 in cavity 20. ln the lower part of block 12 is a similar valve seat 14, lwith valve 15 also normally pressed against seat 14 by spring 16 in similar cavity 16a.
On the outside of lower end of barrel 7 is threaded a collar 21, the lowei1 edges thereof turned inward on a curve against the outer walliof barrel 10 and a tight oint with slidable motion is provided by the packing 27 Which'rests on the curvedseat 21 caused by the turned in edge f 2l, thus assuring, Va tight joint Withoi'itrtlieV danger of jamming` and creasing` which often occurs when sueh packing is bent on a lrightV angle, the packing is held in place from above by a collar 28, on top of which is placed a fibre Washer or butler ring `29, `Which strikes against the shoulder l2 and limits the up- 'Ward stroke when barrel y7 is raised.
' footl piece 30 has anupWaid 'facing cup V31 into WfliichisV'thr'eaded the lower end of barrel' 10, a nipple lug 32 extendsfroin one l'side'of Slupon which ymay be attachedY any suitable'air hose ormeans 'tor conveying fthe compressed air toa tire or other receptacle tobe filled, aepassageway K extends from the interior chamber J throughthe lug Yc'ipposite lug "-aipassagewayfo'ff any suitable form for re- "Anotlierlug' 33'is disposed on'tliepart- 3l 32, which' is also provided 'with eeivi'ngan aire gage' 'of f any commonly used 4"typewith a! movable! plunger 3d, but it is inetl Ideemed* necessary to further illustrate `the gage, the base oit which receives the presi; -sure'ot the air in chamber-J5 and the plunger 34E 'is extended 'outward in accordance with the anion-nt ot' pressure exerted by the conipressed air in J. iv'l'oclc plate 35 is hinged "at BG-to Joot vplate 30 and lcarriesa hook at try marks will show the amount of pressure its outereiid 37, and -aseries of numbered registry Vlines 38, and when the plate is turned doiynasshown in full lines, the outer end of plunger 34- as extended over the regis- `in the chamber il.
Vhen barrels and 10 are telescoped upon each other as 'Faras possible the lock: plate inay beturnedup and the hook 37 then passes over" the top ot collar2i, as shown 1n dotted lines in Fig'. 2; thus securely lock- Ving:l the barrels against :further action when the A)um i is tol be trans )orted or not in use" 1 llhisis important asordinary pumps quently become extended iii transportation,`
4and when extended i they take upv more spacev and dust anddirt- `collects on lthe bearging' surliaeesol' the-barrels and causes itriction and weaifthereafter when 'the pump is operated. K VIn operation the handlel Vis raised which lincreasesv the v'capacity of chamber C yand air"` then rushes therein Ythrougghf passageways A4-Mandi B4B. `When thehandle is next Jpressed'down' the air in C is held above'by yalVe-"s'o is forced down through? the pas# sages DV and E over Valve 18 vinto outer :chamber F, Wliiohisismaller in 'space than` the'exte'nded chambery@ and the air is acj-.
oordingly compressech'and such compression being' on the down stroke lis much easier accoinplish'ed by hand than on au upward `stroke. A'second'raisc of the handle ,draws upward collar Q1 and packing 9.7 and forces "storage chamber;

In my invention also: no. piston. is necessary other'than one of Vthe barrels Whichalso serves as a storage chamber.
