T all whom it may concern:
Be it known that l, JOHN /Vnisnsnonn, citizen of the United States, and a resident oi uincy, in the county of Adams and State ol 1 l1I101S have invented a new and, lm'iroved 1 l This invention is annnprovement in en- .gines, relating primarily to internal combustion engines of thti two-cycle type, and having in vlew the provision of an engine construction by which perfect lubrication of allworking parts is eliected; this being accomplished in a manner both economically and I [structe automatically.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts inboth views. Figure 1 is a central vertical section through a two-c cle internal combustion engine conin accordance with my invention;
and Fig. 2 is a similar fragmentary section substantially on the line 2-2 of Fig. 1.
In the construction of an engine in accordance with my invention, I employ an upright cylinder 5 of the usual or other preferred type. having any desired diameter of. fuel admission exhaust and s )arking device, and provided with a piston-head 6, which is constructed with a circumferential groove 7, passing around the body thereof at substantially the center. Journalcd in the piston in the plane of the groove 7 is the usual cross or connecting-pin S, rigidly attached interme diate its length to a pitman 9, the latter be ing journaled at its lower end on the cranlo pin 10 of the crank 11. The lower portion of the piston-head, shown in Fig. l, is extendcd at the opposite sides of the pitman to provide extending bearing surfaces '12, which pass into a cu) 13 formed integral with or otherwise rigir y attached to the pitman l), and are provided with oil or lubricating passages 14, which lead from the circumferential groove -7 underneath the end portions of the cross-pin 8; this construction ot the o1l--ways obviously ei'lecting lubrication between the piston-head and. cylinder, the pistonhcad and cross-pin, and the piston-head and bear' ing surfaces of the. pitinan. The cup 13 at its bottom coi'nicc ts with a passage 14 mssing transversely through the pitman, which in turn communicates with a passage 15 passing longitudinally through the pitman to the crankpin.
l l l I At the opposite sides of the cylinder,.thc discharge pipes of suitable lubricating cups 16 connect; the connection of these pipes being of such an elevation to register with the circumferential groove when the piston and connected parts are at the lowest position of theirmovement. As engines of this character when stopped usually stop on the lower center, the discharge from the oil-cups will be in register with the oil passages, which will 'lill up during the time the engine is idle, or, if
the engine does not stop on its lower center,
it may be moved to this oosition and the sev-- eral oil passages placer in communicationwith the oil-feed. The oil as it passes from the piston-head and drips in the cup of the pitman is fed through the pitman to the crank-pin, and thus repeatedly and hence economicallyq,used. During the running of the engine, the lubrication may obviously be continued, iL-Slnitll quantity of the lubricant passing into the circumferential groove at each com lete stroke of the piston. ranging the oil-cu )S at opposite sides of the cylinder, the feed is much more in ilorin about the piston than would otherwise e the case, and since the connections of the oil-feed pipes are in a plane with the crosspin, the flow of the lubricant under this pin will not be impaired by the clogging up of the circu1 n lercntial groove.
The invention as shown and described while being the preferred embodiment of my improved lubricating arrangement, the same may nevertheless be modified within the scope of the claims annexed.
Having thus described my invention, .1 claimas new and desire to secure by Letters Patent:
p 1. in an engine, an upright cylinder, a piston movable therein, having a circu1nferential lubricating groove and provided with lubricating passages leading through the bottom thereof "from the groove, a crank having a crank-pin, a pitnian connecting the piston with the crank-pin between said passages and contiguous thereto, and a cup carried by the pitman under the oil passages,
discharging through a passage in the pitman By arton movable therein having a circumferential oil-groove and provided with oil-ways leading through groove, a cran having a crank-pin, a pitlnan connecting the piston with the crank-pin between said oil-ways and contiguous thereto, a cup carried by the pitman under the 011- ways, dlscharging through a passage 1n the pitman. to the crank-pin, and lubricating,
eeding means carried by the cylinder,
adapted to register with the circumferential groove of the piston when the piston is in its lowest position of movement.
4. In an engine, a piston having a circumferential groove, a cross-pin journaled in the piston in the plane of said roove, and a pitman fixed intermediate t e len th of the cross-pin, said piston having ubricating passages passing under the opposite ends and contiguous to the cross-pin from said oove, and thence discharging through the ottom of the piston contiguous to the adj acent bearing facesof the pitman.
'5. In an en ine, a piston-head havin a cireumferentia groove, a cross-pin journa ed in the head, a crank having a crank-pin, a pitman fixed to the cross-pin and journaled on the crank-pin, said plston-head having the bottom thereof from the lubricating passages passing from the groove under the opposite ends of the pinand contiguous thereto, and then dischargingthrou h the bottom of the piston contiguous to t e opposite faces of the piston, and a eu carried by the pitman, located under the ischarge of said passages and having a passage leading to the crank-pin.
6. An engine comprising a cylinder, a piston movable therein hav ng a cross-pin, a
crank-pin, a pitman connecting the crossjournaled on the erankzpin, and a lubiicat- *55 a passage leading through tI1eing cup surrounding an secured to the pitman, having pitman to t e crank-pin.
In testimony whereof I have signed' myf name to this specification in the presence of two subscribing witnesses.
