Claims.

This invention relates to means for preventing waste grabs in railway journal boxes. It frequently happens that journal bearings run hot by reason of the fact that the packing waste will be caught between the journal brass and the axle.

While it is realized that others have worked on the problem of preventing waste in the journal box from getting between the brass and the axle, it seems that the actual cause of this condition has been generally over-looked. When a railway car is bumped sufficiently hard, the journalbrass will actually lift above and travel to one side of the axle within the limits of travel of the axle in the journal box. When this occurs, the axle will, in relation to the brass, travel diagonally downward toward one side of the journal box directly against the waste packing. Thus, the axle will apply pressure on the waste at this side of the box. The only way for this pressure to be relieved is for the waste to move around out of the way and thus be forced up on the opposite side between the axle and the journal box, which side is where the greatest opening exists between the brass and the axle. Consequently, when the brass again drops down into position on the axle, it is likely that some of this lifted waste will be caught there-between.

It is a primary object of my invention to provide means which will automatically close off this opening and at the same time be normally in such position that there will be no interference with the proper lubrication of the axle and no interference with packing irons and the like. v

These and further objects and advantages of the invention will become more apparent to those skilled in the art in the following description of the invention which is made in reference to the accompanying drawing, inwhich Fig. 1 is a vertical transverse section through a conventional type journal box;

Fig. 2, a top plan view of the journal brass with the invention applying thereto;

' Fig. 3, a side elevation of the invention ap plied to the brass; and i Fig. 4, a detail in section on the line 4-4 in Fig.

Like characters of reference indicate like parts throughout the several views in the drawing.

Referring first to Fig. 1, the usual journal box i0 is provided with a curved floor on which is carried a quantity of oil saturated waste H of a sufficient depth to bear against the under side of the car axle l2. The usual journal brass l3 rests on the upper side ofthe axle l2 and is positioned between inwardly extending shoulders l4 and I5,

against which from their outer side abut the brass lugs l6 and 11, all in the usual and well known manner.

These shoulders l4 and I5 are cut away beginning at an elevation under the brass l3 to curve outwardly and downwardly into the wall of thebox l0. Also, there is generally present within the box l0 inwardly extending portions I8 and IQ of the box wall to provide external clearance for bolts and 2|.

The packing waste extends throughout the length of the box l0 and around these projecting portions 18 and I9. The axle I2 is lubricated by picking up oil from the contacting waste H and having the axle carry this oil around under the brass I 3. Excess oil is wiped off of the axle at the line of contact between the brass lining 22 with the axle. With properly shaped brasses, this excess oil will flow outwardly on the brass and drop back down on to the waste I l without striking the axle. This excess oil serves to cool the axle l2 and carry away the heat generated by the turning of the axle under the brass.

With the foregoing construction and conditions in mind, I apply a pair of gates to the brass 13. Each gate 23, Fig. 3, consists of a plate of metal hinged to a bracket 24 which is removably attached to the side of the brass l3. In the form herein shown, a plate 23 is provided with a pair of pins 25 and 26 spaced above the upper edge of the plate and directed one toward the other.

The bracket 24 consists of a horizontally disposed length of metal and having upturned ends 21 and 28, and their respective'fingers 29 and 3!) turned over from the upper portions of these ends to be directed substantially one toward the other in approximate parallelism with the horizontally disposed bar. On the outer sides of these ends 21 and 28 are provided suitable sockets to receive the pins 25 and 26 in such a manner that will permit the plate 23 to hang freely from the J bracket 24 and swing therefrom. These sockets may be formed as indicated in Fig. 4 to have an initial U-shape in cross section with an opening at the top so that when the plate 23 is to be attached to" the bracket 24, the plate 23 may be presented to the bracket to have the plates plane horizontally disposed, in order to drop the pins 25 and 26 downwardly into these sockets, whereupon the plate 23 may be released to allowitto swing v downwardly to a vertically disposed position. The upper ends of the respective sockets may then be bent inwardly a sufficient distance soas to prevent the accidental displacement of the pins therefrom.-

The bracket 24 is made to have a suitable length and height so that it may be slipped over the projecting lugs I6 and I! over the brass I3, the vertically disposed ends 21 and 28 coming up across the respective ends of the lugs and the fingers 29 and 30 extending over the top sides thereof. Preferably, the fingers 29 and 30 are initially turned downwardly slightly so' as to re,- quire spreading from the bar of the bracket in order to insure a compressive grip on the bracket between the fingers and the under bar.

These gates 23 are assembled on the brass I3 before the brass is inserted into the box I over the axle I2. When the brass I3 is in position as indicated in Fig. l, the bracket 24 in either case can not move toward the axle I2 by reason of the upwardly inclined face of the brass I3 preventing such movement. Neither can the bracket 24 shift outwardly for the reason that it will strike, principally by its under side, the shoulder I4 or I5 as the casemay be. Of course longitudinal movement along the brass is prevented by reason of the upturned bracket ends 27 and 28. Therefore, the gates 23 are positioned to hang normally in fixed relationship with the axle and the side wall of the journal box III. This position is such that the gate 23 on either side of the axle I2, Fig. 1, hangs downwardly vertically and spaced from the axle. This means that the down flowing excess oil is not interfered with, but in fact may be aided by pro viding a surface down which the oil may. flow. Also, each ofthe plates 23 hangs at a distance inwardly from the projecting wall portions I8 and I9. This spacing between the plates and these projecting portions permits the waste packing II, to be worked down under the axle in the usual manner, by the customary tool or bar without in any way interfering with that action or requiring the handling of either gate 23. The gate 23 on each side is further protected at its wall end by reason of the fact that it hangs behind the annular fiange 3I on the outer end of the axle.

Now assuming that the car which is carried by the box I0, is bumped from the right hand side, Fig. 1, the brass I3 will be lifted to leave the axle I2 is a position indicated by the dash lines. Since the gates 23 arehinged to the brass which in this case is the moving part, these gates by reason of their inertia will swing as indicated by the dash lines. Thus, it isto be seen that when the axle I2 pushes down on the waste II to forma depression therein to substantially define the dash line position, the displaced waste moving up on the left hand side of the journal at that instant can not enter the opening between thebrass I3 and the journal I2 since the gate 23 on that side has swung to the right over toward, if not against, the axle I2 closing off admittance to that opening. Waste coming up therebehind will tend to hold the gate over that opening so as to further prevent the waste from entering therein. The gate 23 on the right hand side of the axle will, of course, not exert any particular effect in this operation. However, since the car is designed to move in either line of travel, a gate must, be provided on either side of the axle to take care of the movement of.waste when the car is struck from the other side.

It is thus to be seen that when the weight of the car carries the brass fI3 back into normal bearing position on the axle I2, the brass will seat on the axle without grabbing any waste therebetween. Thisaction is accomplished without applying any of the heretofore devices directly on the waste in an attempt to hold it down, such devices being ineffective for the reason that they become distorted or broken by the side travel of the axle within the box and further prevent repacking of the box without their removal. 7

While I have herein shown "and described my invention in'the best form as now known to me, it is obvious that structural variations may be employed without departing from the spirit of the invention, and I therefore do not desire to be limited to that precise form beyond the limitations as may be imposed by the following claims.
