JOURNAL-BOX.

Specification of Letters Patent.

Application filed June 12, 1914. Serial No. 844,651. 7

To all whom it may concern:

Be it known that we, JOSEPH BLOCKLEY BEADMAN and HARRY JOHNSON MAGKLIN, residing, respectively, at 2 West-View Terrace, Keighley, in the county of York, England, and 49 Lightburn road, Ulverston, in the county of Lancaster, England, have invented new and useful Improvements in Journal-Boxes, of which the following is a specification.

This invention'relates to improvements in journal boxes, more particularly to the type used on railway rolling stock and the like vehicles, and wherein side chambers are provided for the reception of the lubricant in a liquid form. In this type placed beneath and in contact with the'journal whereby the lubricant is conveyed to the axle. .Also, in this type of journal box provision is made for the reception of the surplus oil when the "vehicle is in a tilted position and for siphoning out any water that may have entered the axle box.

Heretofore great difficulty has been experienced in the eflicient lubrication of the journal owing to the difliculty of separating and removing collected water from the oil. The water being heavier in gravity sinks to the bottom of the oil chamber and raises the level of the oil higher than some portion of the back of the axle box, thereby allowing the oil to'run out and be lost. In axle boxes provided with a separate chamber at the bottom difficulty has been experienced in preventing the outlet for the water to escape becoming clogged with dirt, and thus when the vehicle is tilted the water has become again mixed with the oil.

The object of this invention is to construct a railway or other vehicle axle box with means for separating the water automatically from the oil and conducting it into a chamber provided with a suitable outlet through which thewater can escape, and at the same time providing the separating chamber with partitions that will prevent the water, as far as possible, becoming again mixed with the oil.

' The above named object is attained by arranging and constructing the axle box as illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of an axle box with the detachable cover fixed ofjournal box the lubricant is usually raised by a pad thereto and with a water separating chamber attached thereto, and with holes com: mimicating with the space in which the shield slides, and also tical partitions and outlets in such shields; Fig. 2, asection on line A, B, Fig. 1; Fig. 3, a sectional elevation of axle tapering well and a division between the shield guard slide forthe water to pass into the latter and having vertical partitions formed therein; Fig.4, is a section on the irregular line C, D, Fig. 3; Fig. 5, is .an enlarged lower portion of Fig. 1; Fig. 6, is a sec: tional elevation on line E, F, Fig. 5;. Fig. 7, is a part plan of Fig. 5; Fig. 8,.a part sectional view online G, H, Fig. 3. V

Like partsin all the views are marked with similar letters of reference.

a is a railway vehicle axle box of ordinary construction made of iron and steel, 6 the bottom of the same, c the: well or space for the reception of oil, and d the bush. 1 The axle box is provided with a lubricating pad mounted upon springs. These last named parts are not shown in the drawings. e is the axle of the vehicle. The, axle boxes shown at Figs. 1 to 4 are provided with bulging sides f to form an internal recess, or side chamber for the collection of any oil that will run to the side of the axle box when fixed to an end tilting vehicle. g is the shield guide or groove, 7:, its cover, and zthe dust shield which is. usually made of wood. All the above parts are of the usual and ordinary I construction and will be readily understood without further description.

The water chamber 7' is formed either by fixing to the bottom of the axle box a casting y' which is secured in position by means of set screws 7a..(Figs. 2 and 6 or the water chamber may-be formedin the axle boxitself, as shown at Figs 3 andt, in which case a'tapering groove or channel a is formed in the bottom of the axle box, and a communication is formed between the shield. guide or groove 9 by, means of the hole 0. In the former case where, the water. chamber j'is Patented Mar. 9, 1915.

provided with verpart sectional elevation of ,the

formed in a separate casting two holes Z and m are in communication chamber; the hole 7 end with the oil chamber 0, and atits opposite end'with the-water chamber 7', while the with the water Z communicating at one 6 as 1, Q,

narrower in width than compartments 1-:

partment 2. 5"by the vertical partitions p,

F water escapes 5 through the tapering hole r which, as shown exit holes r in 40' to be near bottom of the compartments 1 and 46 shown in dotted 66 It will readily .frcm the Z or n and will rise in thecompartment 2 ends of the hole we communicate respectively with the shield guide or groove 9 and the water chamber. The lower portion: of the shield groove g is thus made to form a 5 chamber for receiving the water that is sepashield groove g and the water from the oil- 0 chamber first passes into the water chamber j by gravity and enters the compartment 2 until the latter becomes full. WVhen the compartment 2 becomes full of water, the from the compartment 2 at Figs. 1 to 5 in the drawings, is arranged just below the dust SlllelCl i.

In some cases 1 and 3, as shown at Fig.8 of the drawings, the exit holes r in each case being arranged to taper outward so as to revent them becoming clogged with dust.

-1, In this latter arrangement when the comeepartinent 2 becomes filled with vertical partitions p and 9 form a kind of weir over which the water can overflow intov compartments 1 and 3, and by arranging the each of these compartments their bottom and the water readilv flows out on each side thereof.

In some cases it may be found more convenient to place the exit holes r, r in the 8, as lines at 1, Fig. 8 instead of at the sides, as shown in full lines in the same view. Or, in other cases instead of employing a hole tapering outward a parallel hole may be employed having an inter- 50 nal screw thread out thereon into which a short elbow pipe r is inserted, as shown in dotted lines at Fig. 8. The orifice of the outer end of the elbow pipe 1' may be either 7. parallel or arranged to taper outward.

be understood that the means for separating the water from the oil is controllable by gravity alone. In the operation the water would collect in the shield groove 9 through which is passes oil chamber 0 through either hole until it reaches the top of the vertical partition 79 and g when it would overflow into compartment 1 or 3 or both, and would after:

ward pass out through the exit hole or holes the lower portion of g which are itfmay be found more pref-' erable to arrange an exit hole in each of the 30' compartments water the made to taper outward and therefore-pro sent very little surface for the dust to lodge thereon.
