13 Claims.

This invention relates to improvements in journal boxes for railway rolling stock and more particularly to journal boxes carrying a lubricant in a Well portion thereof and devices for confining the lubricant and supplying it effectively to a journal.

One object of my invention is to provide an improved oil conveying system whereby positive lubrication of the bearing surfaces is assured at all times.

A further feature of my invention is the provision of an assembly of parts whereby each part is maintained in correct position when in use and its correct location is insured in the course of assembly.

Further objects and advantages will be apparent from a detailed description of an embodiment of my invention illustrated in the drawings in which:

Figure l is a vertical, longitudinal section through a journal box with a journal therein.

Figure 1A is a plan view of the journal box lid.

Figure 2 is a Vertical, transverse section on the line 2-2 of Figure 1.

Figure 3 is a plan view of the oil stripper.

Figure 4 is a vertical section through the oil stripper taken on line 4-4 of Figure 3.

Figure 5 is another vertical, transverse section through the journal box and journal taken on line 5-5 of Figure l.

Figure 6 is a plan view of the brass or bearing member which rests on the journal.

Figure 7 is a vertical section taken on line.

1--1 of Figure 8, and

Figure 8 is a vertical section, similar to Figure 1, of a portion of the construction but showing the journal box raised with respect to the journal, and the oil conveyor and brass out of their correct positions, thereby interfering with insertion of the wedge.

In the drawings there is shown a journal. IIJ rotatably mounted in a journal box II. This journal box may be of standard dimensions and made as a separate unit or cast integral with a side frame as is well understood in the art, and. comprises a casing or main housing I2 provided with a well I3 adapted to hold a supply of lubricant. A plug I4 may be removed to replenish the supply of lubricant and is preferably at the right height in the casing to act as a gauge.

The journal enters the housing through an opening I5 in one end thereof. At the opposite end of the housing an opening furnishing access to the interior of the journal box is closed by a suitable cover or lid I6 hinged about the pin I1.

, formed in the babbitt I8 and the under side of the brass I8. This oil conveying member may be of any suitable type' preferably, however, of a flexible nature, such a's a vchain or belt, and is large enough in circumference so that the lower or freely hanging portion thereof will dip below the surface of the lubricant in the well I3. A chain of the type disclosed in my pending application Serial Number 620,682 may be used advantageously.

A circular opening 22 is formed in the brass, the lower portion of which registers with the groove 2|. A substantially annular shelf 23 is formed about half way down the opening and is adapted to limit the downward movement of an oil stripping member 24 during assembly.

This oil stripper is circularl in cross section and preferably shaped somewhat like a bolt with a very short shanl'. (Figs. 3 and 4). The circular head 25, in its normal position, will preferably remain spaced from the shelf 23 of the oiling cavity to provide a slight clearance allowing the shank to rest on the oil conveyor. This head is provided with a series of holes 26 extending from the top of the head to the bottom thereof, and which may conveniently be connected by a circular groove 21 on the under side of said head. Vertical grooves 28 are formed in the bottom portion of the wall of the opening 22 in the brass, as best seen in Figure 6, and these serve to divide the shelf 23 into two sections. Thus, when the conveyor 20 rotates with the journal, carrying oil up with it, the stripper 24, resting on said oil conveyor, removes or scrapes 01T the oil which may then pass up through the grooves 28 and the holes 26 in the stripper directly, if they coincide with each other, or by way of the groove 21 if the vertical passages are offset from each other. The wedge I9 covers the opening 22 and makes this cavity into a closed pocket.

A small reservoir is thus formed in the brass. During rotation of the journal and oil conveyor, oil is forced up into this cavityv under pressure. At first the oil acting upon the under surface of the head may lift the oil stripper 24.v As the reservoir above the stripper becomes filled, however, the pressure of the lubricant therein forces the oil stripper down onto the oil conveyor and it is apparent, of course, that asthe speed of decreases, the pressure above the oil strippx" crrespondingly increases. Positive removal of oil from the member 20 is thus afforded at all times,'and the stripper 24 which functions like a piston is restrained in its vertical movements.

Also registering with the groove 2i, there are provided substantially vertical openings `29, n2 8! extending through the brass and connecting with grooves 30. 30 in the top thereof. These grooves, extending rearwardly about half the lengtn of the brass, form small reservoirs for the lubricant. Openings 3|, 8| similar to the

openings

29, 29 also connect with these grooves and also with grooves l2. 32 in the lower or bearing side of the brass.

When the oil stripping member is held against the oil conveyor as described above, a pressure is built up on the lubricant carried by the conveyor and this lubricant is forced up through one of the openings 29, depending upon the direction of rotation of the journal, into a connecting groove 30 and is then distributed to the journal and its attendant bearing surfaces by way oi a groove 32.V The operation of this system of oil distribution to the bearing surfaces just ahead of the high pressure bearing areas is more particularly described in Patent 2,024,204 issued to Albert O. Buckius and myself, and in .my Patent 2,024,205, both patents granted December l'Z, 1935.

A projection 33 is provided in the oil well preferably integral with and extending from the casing l2 in a horizontal direction and immediately above the lower portion of the oil conveyor. This guard member is adapted to pre= vent the traveling oil carrying member from wrapping around or sticking to the journal and thus interfering 4with the supply or lubricant thereto and possibly damaging the parts. This guard may be shaped, if desired, to conform with the curve made by the` oil conveyor in its normal passage although other shapes may be used to perform the same function. An upwardly projecting web d4 is preferably provided integral with this guard member and the housing for a purpose which is described below.

The lid i6 may be provided with anv inwardly extending bifurcated flange or rib having arms 35a and 35h adapted to project into the journal box toward the journal when the lid is closed, as may be seen in Fig. 1A. This lid is also preferably provided around its periphery with some suitable sealing means such as a gasket 36 to provide a tight joint when closed.

It sometimes happens during the use of railway rolling stock that the journal box will move upwardly some distance with respect to the journal therein if the car is violently jarred during coupling and the like. By my construction any possibility of the parts becoming dislodged or disarranged with respect to each other and thereun by ceasing to perform their proper function, is prevented. The rib 31, preferably also integral with the casing, prevents the wedge member t9 from sliding out of place during normal operation. If the journal box is raised, however, in the manner mentioned the wedge member might be thrown out through the opening between this rib 3l and the flange 38 on the journal itself. Such a possibility is prevented when the cover I8 ls closed since the projections 35aand 35h effectively closes this opening.

The rib 34 acts to some extent as a gauge. During the assembly of the journal box, the box is usually jacked up or raised as shown in Figs. 7

and4 8. It will be apparent that the extent to which the box may be raised is limited in my improved construction by the rib 3l. If the oil conveying member 20 is in a position to correspond with the groove in the brass I8, so that the latter rests properly on the journal, there will be just about suilicient room to insert the wedge member I9. If, however, the oil conveying member is not in a correct position the forward end of the brass will be held in the elevated position shown in Figure 11 and the wedge cannot then be inserted but will strike the end of the brass. Thus, a reliable means is provided for determining when the parts are in correct relation to each other during the assembling operation. The rib' 3d in addition to aiding materially, in the way explained, in the assembling operations, is also very useiul during the operation of my new journal box since relative movement between the journal box and journal is definitely limited without, however, hampering the normally required freedom of the parts.

It will thus be seen that this construction is adapted to be very readily assembled, disassembled and repaired. Certain portions of the housing and lid are so designed that the parts cannot get out of place during operation and can not be improperly located in the course ofassembly.
