Amalie than filed June 14, 1921.
To all whom it may concern Be it known that I, (ll-innate 1 a citizen of the United States. 11ml Brookline countyof Nortblh. and t' Massachusetts, have invented certain new and useful Improveuuents in internal-lom-- uni sin bustion Engines. fully described and rcpr licient means for accomplishing this result by applying scavenging or piston co1npressed air to prevent the oil being carried upward so as to be blown into the cylii'lder and for returning the oil to the supply, and in carrying out the inventioin'l ynrcl'crabl'y provide chambered Stuliing-boxes tor the pistonrods and supply scavenging or iuiston-conipressed air to said chambers during: the up strokes of the pistons. thereby preventing lubricant working through the stutling boxes from being blown during scavenging); into the power cylinders and burned. witli conscipient waste of lubricant and increased sinoltinces of the exhaust. Any lubri nut that may work into the stallingbox chambers is returned by the air to the oil supply. or other receptacle, for re nse thus securing the minimum of oil waste consistent with e1- ficient' lubrication oi the piston-rods.
F or a full umlerstanding ot' the inventimi. a construction embodying the same in its preferred form, as applied to a two li iider engine, will now be described in detail in connection with the accompanying dra wings, and the novel features thereof then be pointed out in the claims.
In the drawingr- Figure 1 is a horizontal section o'l a two cylinder two-cycle engine. which maybe oi the Diesel type, with enclosed I crosshead guide and crank casing; Figure 2 is a transverse section on the line 22 of 1, and
Figure 3 is an enlarged central section at the piston-rod stuffing-boxes and cross-over connections.
Referring now to the drawings, and particularly toFig. 1, the invention isshown as applied to an'internal combustion engine lipi-ieizlication of Letters Ifatent.

Eerial No. 477,376.
with but two cylinders A, B, although it will be understood that equally satisfactory results may be secured in engines having any number of cylinders. As clearly shown in Fig: 2, the engine in connection with which the invention is shown has inner crosshead guide and crank casings 10 and outer casings 11 which form scavenging? air chanr bers '12, 12 for the respective engines into which air tor scavenging purposes is alternately drawn in on the upstrokes of the pistons a, Z) through automatic inlet valves 1 and compressed in each or said chambers on the downstrokes ot' the pistons, the piston rods 2, 2 passing through stutling'boxes at, i mounted above the cross-head guides as usual.
In order to prevent lubricant-adhering to the piston-rods from working up' through the stalling boxes. with consequent loss thereof by burning and increased smokiness ot the exhaust as a result, the stufiing boxes 4:,
4t are provided with chambers 5 (Fig 3), preferably formed by the insertion of lantern glands 6 between the usual packing rings. These chambers 5, when so formed, are provided with inlet and outlet channels 7., t-l. respectively, formed in the stufiing box walls in any suitable manner, and the inlets T have tapped thereto crossover eonnections E) leading from each stuffing box inlet 7 to the scavenging air chambers of opposite cylinders. The connections 9 are preferably proridcd with noz'l-return valves of any welldmown type, indicated generally at 13,
to prevent back-flow.
From the foregoing it will be obvious that, as the cranks (l are set at an angle of 180 apart. the pistons (I, Z) will of course reciprocate alternately. Assuming now that the parts are in the positions shown in Fig. 1, that is. with the piston a about to begin the down-stroke air compressed in the chamber 1.2 by the downstroke of the piston will be glorced through the connection 9, past nonreturn valve 13, to chamber 5 of stuffing box 4-, and such pressure will be maintained in such stulling box chamber until the pistonrod 2 passing through stuffing box 4 begins its down-stroke. The maintenance of this air pressure in the piston rod St-ll'fllIWHlJOX chambers 5 eiiectually prevents passage ol lubricant beyond such chambers and any lubricant collecting in the chambers 5 will be forced through the outlets 8 and such oil returned to the crank casings, in the constructlon shown, or elsewhere it desired,
It Wlll be understood that various changes may be made inthe construction and still be Within the scope of the claims, and that While the invention is especially applicable to multiple cylinder internal combustion engines of the two cycle type illustrated, it may be applied with equal advantage to other engines in vvhich pressure is similarly available for oil recovery.
What is claimed is: 1. Means for conserving lubricant in en- 'nes com risin a chamber 0 en to the piston rod for receiving oil therefrom, and
' means for supplying a piston-compressed medium to said chamber and delivering oil therefrom.
2. Means for conserving lubricant-in engines, comprising a piston-rod stufiing box having a chamber'therein, and means for" supplying a piston compressed medium to ti'ple cylinder internal combustion engines, comprising chambers receiving oilfrom lubricated parts of said engines, outlets, therefor, and cross-over connections between the respective oil chambers and scavenging air chambers of other cylinders for supplying air under pressure to said oil-receiving chambers.
p 5. Means for conserving lubricant in multiple cylinder internal combustion engines, comprising stuffing boxes for the respective piston-rods having chambers therein, outlets therefor, and crossover connections between the respective oil chambers and scavenging air chambers of other cylinders for supplying air under pressure towsaid oil-receiving, chambers.
6. Means for conserving lubricant in multiple cylinder internalcombustion engines, coniprising a plurality of piston-rod stufiingboxcs having chambers therein, outlets for said chambers, outwardly opening check valves in ,said outlets, cross-over connections between the scavenging air chambers of other cylinders and said stuffing box chambers for supplying piston-compressed air thereto at pre determined intervals, and non-return valves in said cross-over connections.
In testimony whereof, I have'hereunto set my hand.
