OILING DEVICE.

Specification of Letters Patent. Patented Sept. 14, 1915,

Application filed August 19, 1913. Serial No. 785,591.

To all whom it may concern:

Be it known that I, James M. CUNNEEN, a citizen of the United States of America, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Oiling Devices, of which the following is a specification.

This invention relates particularly to the splash system of lubrication adopted for engines of various types, which consists in partly filling the crank-case of an engine with oil, or oil and water, and depending upon the churning thereof by the crankshaft for spattering some of the oil over the parts to be lubricated.

The chief defect in the aforesaid system of lubrication, as applied to an upright en gine or analogous machine, is that the oil fails to reach the piston, or other similarly moving part located above, regularly and in sufficient quantities to prevent undue friction and heating at the joints, with the result that the piston-pin and brasses, for instance, quickly wear out and must be replaced oftener than would otherwise be necessary.

The present invention aims to obviate this defect by providing an automatic lubricator whereby a fair volume of the oil can be carried up. from its container in a continuous stream, instead of by splash alone, and properly delivered to the jointed parts.

Referring to the drawing hereto annexed, for a detailed description of the invention, Figure 1 is a sectional elevation of a, well-known form of compound steam-engine, to which this improved oiling device has been applied, the same appearing therein in two different positions, to wit, in and out of the. body of lubricant poured into the crank-case. Fig.2 is a top plan view of the device detached. Fig. 3 is a vertical longitudinal section on the line 33 of Fig.

in section, representing a piston an connecting-rod with the device thereto attached. Fig. 5 is a perspectiveview of an outer box or bucket forming part of the device, when used complete.

In the said drawing, the numeral 11 designates the crank-case of the engine, across which the crank-shaft 12 is mounted. 13 represents the connecting-rods, and 14 the pistons. The lubricant about fills the lower half of the crank-case, and usually consists of water and oil, poured therein to a level coinciding approximately with the lower line of the bearings for the shaft journa s.

The lubricating device forming the subject-matter hereof comprises, first, What may be termed a plunging receiver 15, consist-ing of a valved casing which is conveniently made rectangular in shape as shown, and is designed for attachment to the lower end of either connecting-rod 13. A lug 16, projecting upwardly from the casing 15 at the rear edge thereof, afiords a suitable hanger for suspending it from the connecting rod, to which it can be rigidly secured by passing through a hole 17 of said lug, the lowermost bolt 18 employed for holding in place the box 19 that supports the crank-pin 20, Fig. 4.

Ports 21 are formed in the bottom plate 22 of the casing 15, to admit into the latter some of the oil from the crank-case, as the connecting-rod dips therein with the casing attached, at every revolution of the crankshaft. These ports are controlled by gravity valves 23, seated upon the inner surface of the plate 22, and equipped with interposed packing 24. The said valves are guided both from within and without the casing, each by an upper stem 25 and a lower stem 26, respectively adapted to slide through suitable perforations in an internal bar 27 and an external bar 28, which bars are united centrally by a screw-rod 29, secured thereto and to the said bottom plateby appropriate nuts and washers, as best seen in Fig. 3. The bottom plate is made removable to facilitate the mounting of the valves and their guiding means thereon prior to insertion in the casing. When the several parts have been. properly set, the plate is secured in position by screwing it to and under an inwardlyprojecting flange 30, provided on the walls of the casing, near the bottom.

The oil that enters and fills the valved casing 15, owing to repeated reciprocation of the oonnecting-rod from which it is suspended in the body of oil contained in the crank-case, finds its outlet through an orifice 31, provided at the top of the casing and fitted with a delivery-pipe 32. This pipe leads up the side of the connecting-rod to the point where the latter is jointed to the piston by the pin 33, and boxes or brasses 34, substantially as indicated in Fig. 4. A

noz zle or bent portion 35 of the pipe 32 discharges the oil directly and positively onto the pivot-pin at the juncture of the brasses. The pipe, it is understood, may be stayed at any point along its course, if desired, by lateral attachment to the connecting-rod.

Constructed as above described, the device includes a sufficient number of parts to render it operative for the purpose herein stated, especially if a small amount of oil only is required for lubrication. To make it more complete, however, it is furnished with an outer boX or bucket 36, fitted to slide overthe casing 15 from the bottom thereof, and held between springs 37, 38, coiled around a downwardly-projected extension 39 of the before-mentioned screwrod 29, which extension passes vertically through a central hole made therefor in the bottom of the said bucket. As seen in Figs.

2 and 3, the casing 15 and bucket 36 are spacedapart' from each other and held in correct sliding alinement all around by ribs 40, formed on the sides and ends of the casing. These ribs afford enough clearance to avoid frictional resistance of the lubricant in which the device is immersed, so that I the bucket fits loosely over the casing at all times and admits of being slid on and off the sides of it by centrifugal force as the connecting-rod to which the device is attached reciprocates in the crank-case of the engine. The oil enters the bucket through openings 41, which are provided in its upper part and arranged preferably in three rows following one another at the same level, on the two ends and one side of the bucket, as illustrated in Fig. 5. The openings ll let the oil down directly into the bottom of the bucket when the casing therein emerges out of the body of lubricant contained in the engine crank-case, on the upstroke of the plston, as shown in Fig. 1 on the right-hand side, in which event the bucket drops by gravity until the rows of openings are below the bottom of the casing, the springs 37, 38, being sufficiently light or elasticto admit of this movement, and preventing jar and concussion of the contacting parts. On the down-stroke of the piston, illustrated on the left in Fig. l, the oil that has collected in the bucket is retained therein until it reaches the valved bottom of the casing 15, into which it is then forced, due to the rebound or upward sliding motion of the bucket over the casing, which is aided somewhat by the outer pressure exerted by the body of the lubricant upon the bottom surface of the descending device. A flange a2, formed exteriorly around the lower part of the casing, and fitting the inside of the bucket, preventsoutfiow of oil over the edges ofthe latter, when the former descends into it. lower ends of the spacing ribs 40, Figs. 2and3. 7

What 1 claim, and desire to secure by Let ters Patent of the United States, is:

1. The combination with an oil container and an element movable therethrough having a jointed part out of the lubricant, of a receiver immersed in the oil by said element, means for conveying oil from said receiver to said jointed part, and abucket fitted over the receiver to entrap the oil and supply it to the latter.-

2. The combination with a receptacle com This fiange underlies the taining oil and a movable element having a part to be lubricated at a distance'therefrom, of a receiver dipped in the oil by said element, means for conveying the oil from said receiver to said distant part, a bucket held in slidable engagement over said cas char ing oil from said casing over the outside part of the element, and a laterallyperforated bucket sliding over said casing,

the latter having a retaining flange operating to confine the oil below the perforations in the former.

42-. The combination with an oil container and an element moved through the same having a remote part to be lubricated, of a receiver plunged into the oil by said element, means for transferring the oil from said receiver to said remote part, and a yieldinglysuspended bucket slidable over.

said receiver.

In testimony whereof I affix my signa-- ture in presence of two witnesses.
