IJOCOMOTIVE JOURNAL LUBRICATOR.

Application filed April 23, 1821.

T0 aZZ whom it may concern:

Be it known that 1, JAMES J. HnNNnssY, a citizen of the United States, residing at the city of New York, county of New York, and State of New York, have invented a certain new and useful Improvement in Locomotive Jou-rnal'Lubricators, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to. make and use the same, reference being had to the accompanying drawings, formlng part of this application.

My invention relates to improvements in locomotive journal lubricating devices, par ti'cularly of the type disclosed in my copending patent applications, Serial Numbers 397 ,341-1 and 397,32, filed July 19, 1920, and Serial Number 352,098, filed January 17, 1920.

The principal objects of my present 1nvention are, to generally improve upon and simplify the construction of the lubr1cat1ng devices. set forth in my aforesaid applications'; to provide a construction wherein the container or cellar of the device is formed in a single .piece, preferably by casting, thereby greatly decreasing the cost of manufacture of the complete device; further to provide a journal lubricating device that has relatively few parts, thereby reducing to a minimum the liability of the device getting out of order while in service; and, further, to provide a lubricating device that is wholly automatic in action and very effective in performing its intended functions.

lVith the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical section taken lengthwise through the approximate center of a journal lubricating device of myimproved construction.

Figure 2 is cross section taken on the line2-2 of Figure 1.

Figure 3 is a cross section taken on the line 3-3 of Figure 1.

is preferably Patented May 23, 1922. Serial No. 463,842.

tical embodiment of my invention, 10, 1O designate the side walls, 11, 11 the end walls, and 12 the bottom of a substantially rectangular container or collar that is preferably of integral structure.

In order that this cellar may be properly applied to the journal of a wheel carrying axle, the upper portions of the end walls 11 are cut away on radii that are slightly greater than the radius of the journal. Formed within the cellar immediately ad jacent to the end walls 11 are vertically disposed pockets 13 that receive combined packing members and dust guards 14 of wood or fiber and which have their upper edges formed so as to fit snugly against the periphery of the axle at the ends of the caring portion thereof. These packing members prevent the leakage or discharge of oil and waste from the ends of the cellar and also prevent dust, sand and like foreign matter from entering the cellar through thejoints between its ends and the ournal.

Formed on the inner faces walls 10, 10 of the cellar substantial distance of the side and in a plane a above the bottom 12 are horizontally disposed shoulders 15 that extend between the pockets 13, and resting upon these shoulders are the side edges of a relatively shallow pan 16. This pan formed of sheet metal and it is adapted to contain waste or like absorbent material and retain the same in contact with the underside of the journal with which the device is associated.

Formed in the bottom of the pan and preferably at or near the center thereof is an aperture 17 and projecting upwardly from said bottom and disposed about said aperture is an annular wall 18, the height of which is practically the same as that of the walls of the pan. Formed integral with the bottom 12 of the cellar and extending inwardly from one end thereof is a block 19, the inner end thereof terminating in a vertically disposed tubular member 20 that is centrally arranged within said cellar. The upper portion of tubular member 20 projects upwardly through the opening 17 in pan 16 and terminates in a horizontal plane slightly above the plane occupied by the top of wall 18. That portion of hottom 12 that is below and adjacent to the lower end of tubular member 20 is depressed to form a sump 21. The bottom of this sump is provided with an opening that is normally closed by a plug 22 and which latter, when removed, permits the liquid lubricant to be entirely drained from the cellar.

Removably positioned in the lower end of the tubular member 20 is a ring 23, theupper surface thereof forming a seat for a disc valve 2 1 and depending from the latter is a loop 25 through which passes a transversely disposed pin 26, the ends thereof being seated in ring 23. Formed within tubular member 20 a short distance above ring 23 and valve 2% is an annular flange 27, the upper surface thereof forming a seat for a spherical valve 28. Bearing on top of this valve 28 and yieldingly holding the same upon its seat is the lower end of a relatively light compression spring 29, the upper end of which bears against a pin or pins 30 that are seated in tubular member 20.

Formed through the lower portion of block 19 is a longitudinally disposed bore 31, the outer end of which is closed by a plug 32 and the inner end communicating with that portion of the chamber in member 20 between valves 24: and 28. Arranged for reciprocating movement within bore 31 is a piston 33 that is connected by a strap 34: to a plunger 35 and the latter being arranged for reciprocating movement in a bore 36 that is formed in block 19 above and to one side of bore 31. The inner portion of plunger 35 is reduced in diameter and arranged thereupon and bearing against a shoulder at the inner end of said reduced portion is a compression spring 36 that yieldingly resists inward movement of said plunger. The outer end of plunger 35 is adapted to engage the inner face of the hub A of the adjacent wheel and which latter, it will be understood, is carried by the axle B having the journal to which the lubricator is applied.

My improved lubricating device thus constructed is applied to the journal of an axle and maintained in position in any suitable manner. Before installation, the pan 16 is packed with waste or like fibrous material and a supply of liquid lubricant is delivered into the cellar through a suitable filling spout S that is located at the inner end of said cellar.

It will be understood that all car axles, in addition to their rotary movement, have a certain amount of longitudinal movement, that is, a movement transversely of the car or locomotive body and in my improved device this movement is utilized for pumpthe liquid lubricant from the bottom of the cellar and the sump therein, upwardly into the body of fibrous material that is supported by pan 16 and makes direct contact with the journal.

As axle B moves lengthwise in one direction, it forces plunger 35 inwardly against the resistance offered by spring 36 and such inward movement is transmitted to piston 33. As the latter moves toward tubular member 20, a portion of the liquid lubricant in chamber 31in front of said piston and in the chamber between valves 2d and 28 will be forced upwardly through tubular member 20 past valve 28 and a corresponding amount of liquid lubricant will be discharged from the upper end of said tubular member directly into the center of the body of waste to be distributed thereby directly on the surface of the journal. As the axle moves in a reverse direction, plunger 35 and piston 33 will move outwardly under the influence of spring 36 and as a result of the suction produced in the inner end of chamber 31, valve 24 will be unseated and an amount of liquid lubricant corresponding to the amount discharged from the upper end of tubular member 20 on the pre vious inward movement of the parts will be drawn from the sump into the chamber between the valves 24 and 28.

Thus it. will be seen that I have pro vided relatively simple and eiilcientmeans for utilizing the longitudinal movement of an axle for effecting a constant lubrication of the journal of the axle while the latter is in operation and said'lubricating means being of such structure as will enable it to be easily and cheaply produced, and requiring no attention while in service other than the maintenance of an adequate amount of liquid lubricant within the cellar.

It will be readily understood that minor changes in the size, form and construction of the various'parts of my improved device can be made and Substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:
