quiring lubrication through a suitableelement attached to and carried by the-bear-` in 'or member to-'be lubricated.
` `lvhle'fthe system has 'a wide field of application, it is designed primarily for use in applyiiigoil to the various bearings of motor vehicles, and does away with the ne'- cessity of grease cups and the charging apparatus therefor, such as grease guns,some of which are designed to be successively interlocked to the various cups to charge the same at which time the gun is manually operated to force the grease to place.
The main object of the invention may be said to reside in 'the provisionl of means which, when manually held in proper juxtapositon with the member or bearing -requiring lubrication, will automatically force the oil to place, the feed of oil immediately ceasing the moment the oil conducting member or element is manually withdrawn from:
operative position or relation.
The system is entirely automatici aside'y from the mere manual operation of presenting and holding a nozzle to the nozzle guide lor receiving member attached to the element to be oiled.
One embodiment of the invention which has been successfully used is disclosed in `the annexed drawings, wherein:
Figure 1 is a sectional elevation of the structure, the same being disclosed in operative relation to a shackle bolt with .the valves unseated and the oil owing as indicated by the arrows to the`oil passage in thel bolt.

der compression through the action of the spring urged piston.
Figure 3 a sectional view of a container from which 'the oil is exhausted, the conduit disconnected therefrom, and a draw rod attached to the piston for the purpose of re# tracting the same for rechargingpurposes. v Figure 4 a sectional view of the nozzle receiving member with its cap or closure thereover, and b Figure 5 a perspective View of such mem- In the drawings, l denotes a reservoir, the main bodywhereof is cylindrical in form. The upper portion of the reservoir isV tapered or conical as at 2 and terminates in a threaded nipple 3. A hollow fitting or extension piece 4 is screwedupon the nipple,`the. fitting having adjacent its outerl end an interiorly arranged valve seat 5v against which a valve 6 is ynormally held by a spring 'l' interposed between the valve and a threaded plug 8 having an opening therethrough.
Mounted within the cylindrical portion of the reservoir is a piston 9 provided on its under face with a centrally disposed in teriorly threaded stud 10.
A spring 11` underlies the piston, the spring at its lower end bearing against a head 12 screwed-or otherwise secured in the lower end of the body 1, and provided vvith aid aperture 1s provided for the introduction of a draw rod 14, the inner end whereof is threaded andengages the stud 10, see Fig. 3. The rod is threaded from about its center-to its outer end for fthe reception of a wing nut 15 which, when it is turned up, draws the rod outwardly and retracts the piston, putting the spring 11 underY com-Q dex from which the oil content of the cylinder may be readily determined by merely passing the rod through .opening 13 until it abuts the stud 10. I
The degree of compression of the spring and the position of the piston is also determinable byreading the scale as the rod is drawn outwardly under the action of the wing nut. l
When the rod is removed and the spring consequently released, the piston forces the oil upwardly and the oil co-acts with spring 7 to force and hold the/valve 6 to its seat.
The upper end of fitting /i is threaded, and a nut or threaded collar 1'? is adapted to engage therewith, said nut forcing and holding to place a spigot member 18, a packing washer 19 being interposed between a shoulder 20 on the spigot and the upper end of fitting 4.'
The spigot is of such length that its inner or lower end extends beyond the valve seat 5 and consequently moves the valve away from its seat. Said inner end is cut away as at 2l so that the oil may pass around the valve and outwardly through the spigot. A flexible conduit 22 is connected to the outlet of the spigot and extends and is connected to a cap piece 23 which in turn is secured to a nozzle 24. Said nozzle which is preferably circular in cross section, is hollow and is provide-d with an end discharge aperture 25 normally closed by a valve 26 held to a sea-t 27 by a spring 28, The valve 26 prevents passage of any oil from the cylinder and conduit until` it is uneeated, the oil under pressure assisting the spring in this action. The oil under pressure immediately passes into the conduit when the spigot 18 is secured in place on the reservoir.
29 denotes a shackle bolt, which, as will he understood, is the equivalent of any other member to be lubricated, said boltr having mounted in the outer end of a bore formed therein a receptacle or receiver comprising a 'threaded hollow stem 30 and a body 31.
The body is hollow and et' an internal diameter such that the nozzle 24 may be readily inserted therein and as`readily Withdrawn. Mounted within the lower wall of the receiver is a tubular member 32, the lower end of which is fashioned with a seat 33 for a valve 34 normally held thereagainst by a spring 35. The tube or tubular member extends upwardly into the body portion 31 and is out away at its sides as at36. A seat or packing ring 3?, such'as cork, is located in the bottom of the receptacle and co-acts with the nozzle when 4the latter is inserted in the receptacle, see Fig. 1.
A suitable cap or closure is preferably,
though. not necessarily, provided for the closure to prevent ingress o'f dirt and dust. An el'ectrve cap is disclosed herein, see Figs. 1, 4 and 5, and may be said to comprise a top 38 having a curled or rounded spring lip 39 at 'one edge, a front or stop face 40, and
.oppositely disposed side walls il and 42, the
latter having ears 43 formed as extensions thereof'. Pins or screws 44 pass through the ears into the body 31, said pins being located to one side of the medial line of the body so that the cap may be swung to its open and closed position, the lip 39, when the cap is closed, hugging the edge of the body 31 and maintaining the cap against accidental opening. Any form of cap may, of course, be employed.
The body of the reservoir is made of strong material so as to withstand hard usage andto prevent deformation thereof which would interfere with the action of the piston 9. It is designed to have the filled reservoirs kept in stock so that the user of the apparatus may turn in his exhausted reservoir and receive a filled one in its place. Egress of the oil from the reservoir kept in stock is prevented by the valve t3 and the user merely disconnects the spigot from his eX- hausted reservoir and couples it into the charged one. In the act of coupling, the
inner notched end of the spigot contacts the valve and removes and holds it from its seat, the oil flowing outwardly through the -then coupled spigot, through conduit 22 and into the nozzle where its iiowis arrested by the valve 26. The apparatus is then ready Yfor use and'all that the operator has to do is to swing the cap to open position and insert the nozzle into the receptacle or receiver 31. As the lower end of the nozzle contacts washer 37, the upper notched end of the iixed tubular member which passes into opening 25 contacts the valve 26 and moves the same upwardly away from its seat. The oil under pressure may then pass from the nozzle, and flowing lthrough tube 32 forces valve 34 from its seat and continues on to the element to be lubricated.
For ordinary lubrication the nozzle need be held in place only momentarily, and, as will be readily appreciated, the lubrication ,willi be speedily elected. No manual operation ot er than the mere placement of the nozzle within .the nozzle receiver tacle takes place, the opening and closing of the valves being automatic, and the oil automatically flowing under pressure from the reservoir. The system as above set forth does away with the use of grease cups and manually actuated grease guns and the various -annoyances incident to their use.
If desired', the amount of oil which is to be passed tothe element to be lubricated may or recepbe determined by the use of rod 14 and nutv l5. The rod being connected to the piston,
The terms ,upp'er and loweras ernployed in connection with the various elements are merely relative and are not to be taken in any sense as terms of limitation.
Furthermore in the broad aspect of the in-I vention, the nozzle receptacle may be omitted so long as means is provided for opening the valve in the nozzle and conducting the oil to the member to be lubricated.
