Application August 9, 193s, serial No. 223,914
requisite quantities to the iianges of locomotives i driving wheels and other wheels in orderlto reduce wear, to facilitate the movement of the vehicles about curves, and to compensate for the friction due to the lateral movement of locomo- 0 tives.
Another object of the invention is to provide a device of this character which will function particularly in an automatic manner when the throttle is opened. f
A further object of the invention is toA provide a device which will cause the oil to be forcibly siphoned from an oil reservoir by steam action, which involves the same steam action that opens the valve which places the device in lubricating communication with the wheel iianges.
Other objects of the invention are to provide a simple arrangement for accomplishing the above described purposes; to so construct the device as to admit of ready accessability to; interior parts for the purpose of cleaning-draining,
removal and repair of broken or worn parts; and
to lend itself to the proper adjustability of `oil deposit.
With the foregoing and other objects in view,
the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.
In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views.`
Figure l is a vertical section, with parts broken away, showing the improved device as appliedto the iiange of a locomotive wheel, the device being shown in closed position.
Figure 2 is a horizontal section line 2-2 in Figure l, and v Figure 3 is a fragmentary vertical section similar to Figure l showing the parts in open position.
taken on the 55 l2 is designated at i li and I6 designates a threaded bushing through which the oil feed rod l2 extends'whereby the handle l5 lies externally of the device for ease in setting such rod.
The oil is supplied to the Y coupling I4 and oil 60 feed tube `i3 through a connection Il which ex- Referring more particularly to thedrawing ill (ol, isi-s) tends down from a reducer or valve housingy l8r Within the housing is mounted for reciprocation an oil valve i 9 having a bevel seat for closing upwardly against a bevel seat 20 formed upon the lowerreduced and externally threaded end 2l of a hollow barrel 22. The valve-housing I8 may be threadedupon the external threads ofthe reduced end 2|.` Y
1 The valve I9 may be threaded or otherwise secured upon the lower externally threadedend of the plunger rod o-r stem 23 and a lock nut24` serves to hold the valve I9 against displacement `from the plunger rod. l
The barrel 22 is traversed axially `by a bore 25 through which the plunger rod 23 slides vertically o1' axially; the upper portion of plunger rodV 23 having an external diameter substantially the same as the ilnternal diameter of thebore 25 and being tted substantially to said bore with a tight sliding t. However, the lower portion `of plunger rod 23is reduced in diameter forming with the bore 25 an annular chamber 26 communicating at all times irrespective of the position of plunger rod 2li with an oil feed duct 2l which opens through barrel 22 into the interior space of the f oil reservoir 23.' Entrance of oil from reservoir 28 into duct 2l is under the'control of a needle valve 29 which passes through a stuing box 3D and has an exposed end lfsuitable` for receiving a crank, wrench, key or the like retained by some authorized person for the purpose of adjusting the needle valve 29 toward and from its seat 32 in the duct 21. l n
At the upper end of the rod 23 is a plunger 33 traveling in a cylinder 34 and having piston rings 35 and a seat at its lower edge for acting to close against a seat 35 formed in the barrel 22 at the upper end of a large well or socket 31. In the socket is disposed a coil springtacting to nor-- mally raise the plunger valve 33 olf the seatA 36.
`'Iheplunger 33 and itsI plunger rod 23` are traversed from end to end by a passage or bypass 35i placing the chamber above the plunger 33 in direct and open, although restricted, communication at all times withthe lower part or the valve housing i8 below the vvalve l il.
The barrel 22 l projectsy both upwardly and downwardly through the reservoir 28 and may be welded to the reservoir as indicated at 4G and M to produce a tight leak-proof t.
The upper projecting end of the barrel may be externally screw threaded to removably receive the cap i2 through` which steam is led by pipe it from an yappropriate source, for instance from the locomotive valve chest or piston valve. t l
Oil is supplied to the reservoir 28 through a filling neck lill yhaving thereina iilter screen 45, the neck being ordinarily closed by a closure cap t@ having a breather opening 41 therein. At 48 is shown a drain valve. Cleaning plugs downwardly through the passage 39, such steam issuing out of the lower end of the plunger rod and having a siphoning action upon the oil in the reservoir tending to draw this oil out of the reservoir through the duct 2l into chamber 25 and down through the valve housing i3. Here the oilbecomes commingled with the steam and atomized by it to some extent.v
flows down into theoil feed tube i3 and is deposited by the oil feed rod i2 upon the inside` of the flange li of the locomotive wheel. As many feed tubes may be connected to valve housing I8 as there are wheels on the locomotivel or other vehicle.
As soon as the throttle is shut off or the steam pressure above the plunger 33 falls below the value of coil spring 38, such spring will come into action elevating the plunger 33 from its seat 36 and closing the oil valve i9 against its seat 20. This condition of the rparts is shown in Figure 1. Therefore neither steam nor oil will flow out the valve housing I8. However the parts are held in readiness for future o eration as soon as' steam is turned into cap G2.'
As the oil is withdrawn from reservoir 2t air may enter through the breather opening 4'! thus enabling the device to freely function. The amount of oil withdrawn is under the influence of the needle valve 29. Thus the proportion of oil to rsteam may be nicely regulated.
It will be noted that the oil reservoir 28 rsurrounds the operating parts of the device through which operating parts the steam passes thus' communicating considerable heat and raising the temperature of these parts. The parts metal have a high conductivity, thereby radiating heat throughout the body of lubricant in the oil reservo-ir 28. This is important to maintain the oil in a proper condition of fluidity at all times, even in the winter and in cold weather. inasmuch as the faithful performance of the device largely depends upon the liquid condition of the oill` The seat 3E against which the beveled lower edge of plunger 33 engages acts in a dual capacity; rst, thesevparts act as a stop to limit the downward movement lof the plunger and oil valve i9, it 'being desirable that the oil valve` shall not move down far enough for it or its lock nut 24 to engage the lower portion of the mixing housing i8 or to clog the mouth of the pipe connection Il; secondly, these parts form a valve seat sealing the device at 3 to prevent any steam from escaping down upon the outside of the cylinder 3ft past the shoulder 36, thereby forcing all of the steam through the passage 39 and guaranteeing thereby a constant flow of steam to force the oil from the point 2U through the connection i'l and into the tube I3. In this way all of the oil coming out the chamber The mixture' 26 will be forced directly onto the flange of the wheel. y
It will be further understood that in accordance with the present invention the distribution of oil is evenly regulated.
It has been found in some instances during the operation of the device that the needle valve 29 has been tampered with so that the flow of oil through the duct 21 is either too great or too small. Therefore, it is within the spirit of this invention to omit the needle valve 29, leaving the duct 21 of desired size and the stuffing box 30 may either be eliminated or the opening therethrough closed by a suitable plug. In this way the lower valve, I9 and 2li, is found suiiicient for regulating the flow of oil and steam down through the device.
It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
What is claimed is:
l. A wheel flange oiler comprising depositing means forthe oil upon the flange, a mixing housing for oil and steam in communication with said depositing means, a hollow barrel connected to said housing, an oil reservoir extending about said barrel, a plunger rod movable axially in the hollow barrel, a plunger at the upper portion of said rod, an oil valve at the lower end of said rod, said barrel having a valve seat for said oil valve, means for normally raising said plunger, plunger rod and oil valve, a steam head space above said plunger rod in communication with a source of steam supply, said plunger rod having a steam passage extending therethrough and in open communication with said head space and said housing, said plunger rod having an annular chamber thereabout within the bore of the hollow barrel, said barrel having an oil feed duct in communication with said chamber and with the oil reserl voir in all positions of the plunger rod.
