LUBRICATON SY STEM Application filed July 14,
Ta aZZ whom it' may om'wern: y Be'1t'known that I, OTTO IIAENTJENS,'
citizen of the Repblic of Germany, residof double-action pnmps of the general'type illustrated' in my prior Patent No. 1,489,122;
qprior patent above mentimed.
April 1, 1924. -Thefiobject of my invention is to provide a simple and efficient means for efiecting the automatic lubrication of all bearing parts ofthe pump' froni1 au oil snpply in the crank case. v The accompanying drawing shows, in vertical section, a pump in;which my fin vention isemb0died in one form.
Nhile the invention may be embodied pders, p 1ston24 on the.up stroke and'pistorz 25011 the clown stroke.
in pumps of o-ther'construction than that:' shown, I have illstrated a pmp inch in general resembles that disclosed in my.
It" may be appropriately nsed ast0 cfeate avacuum through a suCtion line 15 vhicl1 leads to any appropriate chaniber, 'such' as the'c1s mg of a centrifngal pump, from which air is to be exhausted t0 eflect its priming. The branches 16 and 17 of the snction line '15 lead respectively to annularpassagesl8 andl9, from which rings of ports 20 and 2l,respectively, open to the pump cylinders 22 and 23. lVorking within the cylinders are pistons 24 and 25 at opposite ends of a piston rod 26, connected by a link' 27 to the cran]; 28 on the 1n0tor shaft29. The closed crank case 30 forme; a. ohamber for the reception of a supply of oil 31 which,' according to my present invention, serves for the lubrication of all-beatfing parts.
The lnbrication of the lower oylind'er 23 and the bearingsof the link 27 is effeeted by splash incident to. the rotation of the crank 28, which, dringportion of its rotation, enters the oil in the cranl: case. During operation of the pump, the splashi action of the crank results promptly in filling the crank case 30 With oil vapor. This vapor I now lead to the upper cylinder 322 antomatically through the longitudinal bore 32 of the-piston, the lower end of the bore opening to the crank case, while the upper endopens to the chamber 33 above the upper piston c hamber is closed Tequires' proper lubrication.

by a cap 3tsecured to the upper end ofthe clinder 22. Consequently, as the piston 2l descends't partial vacuum is created in thechamber 33 suflicient to draw :the oil vaporfrom the crank case throughthe bore regulating the deplession created in. the chamber 33 On thefldowh stroke of the pis; ton24, the Cap34is provided w ith ae-regu- 32 and thus lnbricate the wall of the .oylin. ,-der 22. ;In' order' to 'provide means for lating valve 35; 'B y'adjusting the open ing ofthis Valve, a greater or less amonn of air is admitted therethrough to the chamber33 on the.down stroke of the piston. This o f course determines the depression which exists in chainber 33 and tl1uSIcontrols the amount of oilvapor drawn into.
the chamber 33 through'the bore32.
The pistons 24and 25, during theI0peration of theprimp, croate depressions'in the Workingchambers' of the respective cylin- Thse depressio1s in the workmg chambers of thec yhnders tend to cause the 2 l11biiCant entering the opposite ends 'of the respective-cyliridersg to W01li pastthe p1stons andxnitothe work1ng chambers. The ent1re 'cvhnder walls are ths lubricated..-
topermit the air .to escape from therespec tive working chambers as the pistons approach the valves. The piston rod 26 passes tliroughthe hulos 39 and 40 of the .respec" t1ve valves, and its bearing in thosGz hubs The lubricant froin the wall dtcylin'der 22 gathers in the coned upper surface of valve 36 and flows by gravity tOits'bearing hub. Ample lubrica provided in this manner.- 7
Excess oil entering the working chambers of the cylinders in the manher stated, is carried past the valves 36 and 37 by the tien of the valve hnbs on the pisto1irod is e'scaping air when the valves open. In order v between the adjacent ends of the cylinders 22 and 23 is en'closed by a spacing drum4l,
Which is ported at 42 to permit the free esto prevent loss lof thislubricant, the space escaping oil is collected. A return pipe 44 opens from the bottom of the ohannel 43 to the erank case and leads back to the latter by gravity the collected cil.
From the foregoing it is clear that a constant circulation 01 lubricant is eiected through the pump bearings without any other attention than that necessary to maintain the oil in the crank case in proper condition, while exccss oil is recnperated and i*eturned antomatically to the cran]: case.
lVhile the construction shown is simple and xvo1kalole, vnrions modifications vill readily occur to those dealing vrith the problem. which embody the thoughts Whieh underlie the teatures Whicli daim as my in vention.
I claim 1. A pair of algned cylinders, connected pistons working; thevein,- a c1ank to which one of said cylin"s opens, the opposite and of the other cy .ndev being closed, an air admission valve in said closed end foi iegulating the depression in the chamber iormed between said end and one 0' the pistons, and means for leading to said chamber by suction lubricant from the c1ank case.
2. A pair of aligned cylinders having dis charge ports at their adjacent ends, a pair of connected pistons w rking in said cylinders, a ciank case oil snpplv, and means for leading lubricant rom said snpply to the far ends of said cylindevs and discharging excess lubricant from their adjacent ends incident t0 thereciprocation of the pistons.
3. A pair of aligned cvlinders having discharge ports at their adjacent ends, a pair of connceted pistons working in said cylin dors, a crank case oil supply, and means for leading lnbricant from said supply to the ia1 ends of said cylinders and discharging excess lubrieant from their adjacent ends incident to the reciprocation of the pistons, together with a spacing drum between the cylinders adapted to receive the discharged lnloricant, and means for returning said lubricant to the crank case.
4. A pair of aligned cylinders having discharge ports at their adjacent ends, valves :fo1 said ports, pistons working in said cylinders, a piston rod passing through said valves and conneting said pistons, a crank case oil snpply, and means O1 lnbricating both cyiindors and the bearing of said piston vod in said valves irom said oil snpply.
5. A cylihder, a valve at one end thereof, a piston working in the cylinder, a piston rod working throno;h the valve, means for lubricating the oylinoer, said valve being shaped to gatl1er ex'cess lubricant irom the eylinder and 1ead it to the piston rod bearing in said valve.
6. A cylinder cicsed at one end, a piston working in said cylinder, a crank case, a piston rod having a passage opening thereth1ongh from the crank case to the chamber l:etween the closed end et the cylinder and the piston, a regulating valve in saidclosed and for varying the depression in said chaml3er incident to the operation of the piston, and lubricant in the c1ank case passing ihrough the piston rod to said chamber under the influence o:t snob depression.-
In testimon3 whereof I have signed my name to this specification.
