Application llled August 13. 1 907 Serial No. 388.333'.
Patented Feb. lv11, 1908;
To all 'whom-Lt may comer/a:
Beit known that l, ROBERT M. DOWNIE,
a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented a new This invention relates more particularly'l to explosive engines of the reciprocatory piston type, and l the object thereof 'broadly stated, is to provide novel means of Ia simple and enective nature for supplying either a lubricating or cooling ,agent or both to the .f drawings ln t lcasing 7 is provided,"includin piston.' f
In its more specific asfpect, the invention aims to provide means o a ractical nature, which will automatically ta e up the lubricant or a cooling agent from a reservoir and deliver it to the piston and associated pa'rts that are subject to friction and heat,l said means insuring a constant supply underpres- 'sure as lon \as the engine is in operation.
The reerred embodiment of the inveni tion is i lustrated in the accompanying drawing?, wherein igu re 1 is a' vertical sectional view nal channel 'conduit the through the engine. Figs. 2, 3, 4 and 5 are respectively horizontal sections-on the lines 2-2,.3-3, 4 4 and 5`5 of Fig. 1.. Fig. 6 is a detail sectional view-through the lower Vportion of the piston taken at right angles to i .1. imilar reference numerals designate corresponding parts in 'all the figures of the e embodiment illustrated, a crank a column 8 that carries the cylinder mein er 9.' A reciprocatory piston, operating in the cylinder member, comprises aV shell -10 having an end Wall 11 and `cylindrical side walls 12.' side walls are -providedwith'sets of radially disposed channels 13 of the iston which is in sliding engagement 'withV tllie inner face ofthe oylmder. Bearing ysections are detachabl'y fitted in this shell, the upper section beingin `the form of a ca 14 vthat is snuglyiitted in the u per portion of the shell, and is pplovided'wit an upper series of radiating gers 15 'and a lower annular lange`16.- The lower' section 17 is threaded, as shown at 18 into the shell, and constitutes means for maintaining the cap section in place.
'its top with a ch channels 1315` upper end opening ba l nel33 leadingA to the u v venting itsl return. The
lending tothe outer face Y Arotat'able crangk- 19 operates in the crank casing 7, and a pitman 20 havin crank, is provided at its upper end with a ball 21 having a vvbearing between the sections f and partially in each, as will be clear by ref# erence to Fig. 1.
The ,upper or cap section 14 is provided in mber 22 closed by the end wall 11- of the s ll, and an annular chamber PENNSYLVANIA, AssiGNoR To KEYs'roNE DEILijEnV its lower end connectedtoA said 23, surroundin the ball bearing`,'is in coin- 1 munication wit the uppermost chamber 22 through channels 24. This annular cham-- ber 23 is in communication. with the uppermost set of channels 13, and inwardly err-x tending channels '25, lead from the'chamber 23' to the bearing section 17 has its upper corner cut. away4 to bearing. The lower or retaining producefa chamber 26 in communication With-the chamber 23 through chan nels-27, and this .lower section is furthermore provided with another chamber 28 in coinmunication with the 'chamber 26-through channels 29 said chamber 28 being also in communicatipn with the. lowerinost set of The p'itman is provided withalongitudi- ,30, and therefore constitutes a This channel.l 30 communicates lown end ffan air chamber-,31, formed inthe up er end of said p itnmaii, and a discharge con uit 32, depending into theair chamber and having its lower inlet end ortion thereof,- has its located in the louwer t ough the top of the andcommunicating with a supplybham 'permost'chamber 22.I An upwardly opening of fluid throughthe' Inthe lower pprtion of' the channe 30' in thepitman is an upwardly opening balll valve35 and a curved supply l conduit 36 'has its upper end communicating `with the -iihannel 30 below the valve 35i- Thel conduit 36 partially surrounds Athe. crank 19 and is'disposed eccentrically thereto, be-'f ing provided witha lower `open inlet end 37 that is disposed closer to the axis ofthe crank 19 than any other portion of the 1c0nduit This fis an important feature ofthe invention all valve`f34 is prefer ably employed to permit the upward passage conduit 32, while pre- Q -ioo ios
as c learl.yillus-fA trated in Fig. 1, constitutes areservoir for a fluid 39 which may be a lubricant, a cooling agent or both.
N one of the valvemechanism, charge supplyin means, or ignition mechanism is disclose in the drawings, inasmuch as they constitute no part of the present invention, and may be of an suitable character.
The operation of the structure is substantiall as follows. As the piston'reciprocates,
v it will of course be understood that the crank 1.9 is revolvedin the ordinary manner and in the direction of the arrow. Therefore the i .inlet end '37 of theconduit 36 will be forced f axis than any other partof the conduit,'the
.the 'piston in the chamber 22.
fluid will be elevated with considerable force, inasmuch as itsmovement is continuously away from the crank, and consequently cen-. trifual force will assist in the operation. The uid uponveach successive movement of the conduit 36-through the reservoir will be elevated'through the channel 30, and Awill reach the air chamberL 31, finallyv.p`assing through the conduit 32,- past'the valve 34 and being sprayed 'against the 'end wall 11 of From this chamber it `flows into the chamber 23, and thence part will ass through the channels 13 to theNsurface o the piston, .while other portions are'passed through the channels 25 'to the pitman bearing. Other=portiois will gravitate lto the lower chambers and 'thencef to the piston surface, finally escaping and rethe different cha turning tothe reservoir. Inasmu'chas the escape from the piston will be comparatively slow, the supply will causefthe fluid to ac- :cumulatein `the lower portion of the -air .chamber 31 and passing above the lower endof the discharge conduit 32, will compress the air in' said chamber. Therefore a ,constant pressure is maintained -by the compressed air of the Huid through nels is insured. From the fore 'ng,it is thought thatthe construction, .operation, and many advantages` of the herein described invention will bea parent to'those skilled in the art, wit
.out
rther description, and it will beunderstood that various changes'in the size, shape,
proportion, and` minor details of construcv tlon, may be resorted' to without departing from the spirit or sacrificing any of the adi vantagesof the invention.-
