- AUTOMATIC LUBRICATOR.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed'August 17, 1914. "Serial No. 857,075.

To all whom it may concern:

Be it kn" wn that I, DANIEL H. NICKELS, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga, andState of Ohio, have invented certain new and useful Improvements in Automatic Lubricators, of which I hereby declare the following to be a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains to make and use the same. The-objects of the invention are to provide an automatically acting device forrsupplying lubrication to the journal box of an axle or shaft, and particularly adapted to lubricate the journal box of a railway carv axle, so asto prevent overheating the axley when on the road.

Since long distances are traversed by rail- 7 way trains and it is impossible to supply oil to them at sufliciently frequent intervals on route, to prevent overheating a sufficient supply of lubricant must be stored in the journal box to last upon the trip or a large portion thereof, and be automatically ,applied to the axle and journal. To accomplish this object a journal box having a chamber capable of storing lubricant is provided and means are attached to the axle which by the continuous rotation there '1 of will automatically and continuously pour the lubricant thereover.

The invention comprises the construction of box and self lubricating axle hereinafter described, shown in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a longitudinal section of a car axle jour nal showing the storage reservoir and automatic lubricating device; Fig. 2 is a transverse section looking into the box; Fig. 3 is a plan view of the spring which retains the wiper in position; Fig. 4 is an end view of one of the retaining nuts therefor; Figs.

.5 and 6 are side and plan views respectively of one of the retaining bolts therefor; Fig. 7 is a perspective view of the double cup bearing cross bars.

' In these views A is the journal box, hav-.

ing a hooded front portion A, in the lower portion of which the lubricant is stored. Transversely attached to the front end of the axle is shown a cross bar B which rotates freely in the hooded portion of the journal box and in its projecting extremitoward the axle and take the lubricant which projects at C and into the trough shaped openings-d, d, inthe upper face of the bearing D, oil holes d, d lead from these openings to the axle. The front of the bearing D projects at D to so position the openings cl .as toreceive freely the lubricant fromthecups, from which it is conveyed underneath the bearing-D andspread over theaxle'h i The cups 1), b,'in each end of the transverse bar are preferably two in number and are separated by means of a partition I), so as to act as'eiiiciently as possible in each direction as the axle rotates forward and backward. I i 'l A broad annular shoulder Euponwhich and pour it upon the front end of the, axle in and aninlet opening F is formed'therein.

at the lower end through which the cups receive the lubricant from. the body of the journal box and the lubricant is delivered through an opening G at'the'central point above the axle. This shoulder'may be an attached band or ring if desired and of the same or difl'erent substancefrom thatof theI hood or journal box. j

The transverse bar B is preferably secured; to the outer end of the axle by means of one or more studs H, H, which are proa vided with square stems inserted through square holes 6 6 in the bar -B which prevents the studs from becoming loosened and a retaining spring B through which the bolts pass, rests at its ends upon the ends of the bar B andv maintains the bar in contact with the shoulder.

. The nuts J, J, are preferablyprovided with side flanges, j, j, which are passed over the sides of the spring and prevent the, nuts from becoming loosened. These precautions are necessaryon account of the continuous jar to which the axles are subjected.

A trough shaped and inclined member is seen at K which is some what raised above 75 the cups revolve retainsthe lubricant there 1 Having described the invention What I claim as new and desire to secure by Letters Patent is: g

1. In a car axle lubricator, the combination with an axle provided with a pair of bearin ins 01 a lubricant transaortin bar provided with bearing openings mounted on and traveling upon said bearing pins,

a spring provided with openings loosely and movably mounted on said bearing pins and having its ends impinging upon the outer ends of said lubricant transporting bar, and spring retaining members adj ustably mounted on said bearing pins whereby the ends of said transporting-bar may be independently adjusted.

2. In a car axle lubricator, the combination with an axle provided at its ends with spaced bearing members, and a journal box provided with an axle bearing above said axle and a lubricant reservoir below the latter and also having, lubricant ports communicating with said reservoir and said bearing; of alubricant transporting. bar loosely and resiliently mounted .on said spaced bearing members and having its ends provided with lubricant carrying receptacles traversing said journal box and adapted to receive lubricant from said reservoir and discharge the same to said bearingrmember through said lubricant ports, a bow spring provided with openings loosely and movably mounted on said spaced bearing members and having its ends impinging upon the outer ends of said lubricant transporting bar and spring retaining members adjustably mounted on said spaced bearing members and normally interlocking with said bow spring for independently adjusting the ends of said lubricant transporting bar.

' 3. In a car axle lubricator, an axle provided at its end with spaced bearing members, a lubricant transportingba'r provided with hearing openings loosely receiving and taking over said spaced bearing members, a bow spring provided with openings loosely receiving and taking over said spaced bearing members and having its free ends bearing against the ends of said transporting bar, and spring retaining members adjustably mounted on said bearing members whereby said transporting bar is'adapted to ride and travel upon said bearing members and the ends independently adjusted through said adjustably mounted spring retaining members. I

at. In combination with an aXle,'a journal box including an extended front provided with an annular shoulder having lubricant receiving and discharging ports above and below said axle; a transverse bar extending across the front of said axle and'rotatable iusaid extendedcfront, said bar being provided at its ends with oppositely arranged lubricant receiving cups traversing said annular shoulder and receiving and discharging lubricant from and through said ports be low and ab ve said axle, respectively, a bow spring for retaining said bar in place, and spaced bar and spring carrying and adjusting members on said axle upon which the intermediate portions of said transverse bar and bow spring are mounted and adjusted.

In testimony whereof, I hereunto set my hand this 8th may of Aug. 1914.
