Specication of Reissued Letters Patent. Reissued June 30, 1914 Original No. 947,105, dated January 18, 1910, Serial No. 486,497. Application for reissue filed July 21,

To all whom t may 00m-ern Be it knownthat I, JOHN D. JONES, a citlzen of the United States, residing at Walla Valla, in the county of Walla Walla and State of Washington, have invented certain newv and useful Improvements in Axle- Boxes and Dust-Guards; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable Others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in axle boxes and dust guards, or what may be generally designated as journal boxes.

The invention has among its salient objects, to provide a journal box comprising companion members, one of which is a casing or holding member, and the other a removable inner member or box containing the brass'or a bearing member, lubricant retaining means, and dust guard therein, whereby said inner member is adapted to be bodily inserted into and removed from said holding member; to provide in such a journal box, an inner or containing member in which it is possible to place packing material both above and below the ournal proper and thus more uniformly distribute and apply the lubricant; to provide a journal box of the character referred to in which it is possible to apply lubricant directly along the top or bearing surface of the journal; to provide in such an inner box or containing member a bearing member or brass of such construction that lubricant can be applied therethrough to the bearing face thereof and to the top of said journal; and, in general, to provide an improved journal box of the character referred to which is simple in its construction and application, and effective in performing the functions hereinbefore mentioned.

The invention will be readily understood from the following description, reference being had to the accompanying drawings, in which,-

Figure 1 is a longitudinal sectional View showing my invention as applied to a car axle; Fig. 2 is a cross sectional view taken on a vertical line' through the middle of Fig. 1; Fig. 3 is a perspective view of the removable inner box or containing member; and Fig. 4 is a perspective view of a bearing member, adapted to be placed within said inner or containing member.

Referring now to the drawings, a represents a car axle and I) the journal end thereof. c represents the outer casing or holding member, corresponding to the usual car axle box, and is adapted to receive the end of the axle and the journal thereof, as shown. d represents a bearing member or brass provided with a grooved bearing face adapted to rest upon the journal of said axle, as shown. The casing c is provided with an opening for the application of lubricant, j which is ordinarily closed by a screw cap e or equivalent device. The casing is preferably provided across the under side of its top at its outer end with a depending rib f for holding the inner box in place. This inner box is shown in perspective in Fig. 3, and in section in Figs. 1 and 2. It has a bottom g, preferably curved upwardly, as shown at z. and it has an open outer end which is preferably closed by a hinged lid Said inner box is provided on its interior with two upright partitions or walls as j and c, perforated as shown at m for the passage of the journal and axle therethrough. The side walls rise above the top n to form an open space or depression thereabove to retain packing material, as indicated in Fig. 3, with a wedge-shaped opening or passageway 01 through said top leading into the interior of said inner box or containing member.

p represents a hole through the upper part of the partition 7c, through which lubricant may pass to the space between the partitions j and la The side walls of said inner box are inclined, as indicated at e7, from the middle toward the ends thereof. These Walls form a support upon which the holding member c rests, as shown in Fig. 1. By reason of the inclined shape of these walls, a rocking or tilting supporting engagement bet-Ween the inner and outer boxes is provided. Said inner box is provided across the top of its outer end with a depending r ib, as r, adapted to conne the brass d in proper position. Above said rib, the front end wall of said inner box rises, as at s, and is adapted to engage with the rib f on the inside ofthe casing. The brass Z is provided with a wedge-shaped opening, as t, adapted toregister with the opening 0 in the inner member, as indicated in Figs. 1 and 2. The top of the inner box or containing member, the opening t in the brass (Z and the space below the journal b,

and the space above and below the axle a,

are packed with any suitable soft packing u, such as wool.

The vertical chamber or space between the partitions j and 7c is adapted removably to receive the ordinary dust guard, which, as clearly shown in the drawings, is made of wool felt, or other well known material. In ordinary forms ot' axle boxes, when it is desired to renew the dust guard, it is necessary to jack up the ear and run out the wheels. This operation cannot be performed on the road. It requires that the car shall be run into the shop. With the axle box and dust guard of the present invention, such a burdensome and ditlicultoperation is not required. Moreover, the dust absorbent guard can be renewed on the road, and this operation is aseasy as changing.v the brasses. It is only necessary to remove the inner bo-x, withdraw the old dust `guard from its chamber between the partitions y'. and 7a, replace it with a new guard, and reinsert the inner box.

- dinary bOX.

The inner box, with the parts therein contained, it will be noted, constitutes in itself a complete journalbox, adapted rto be bodily inserted iiito the casing,over the journal and end of the axle, or removed bodily therefrom, so that .in case of an accident or damage to one box, it is only necessary to lift the casing in its place until the rib f clears the front end wall of the inner box or containing `member at a, when the inner box with the bra-ss and packing can all be rcmoved together', and another inner box, brass and packing inserted in its place, with. out loss of much time. 4 v

This invention makes possible a great saving of time necessary to put a heated or damaged axle box in condition for use. It simply means the substitution of a fresh box, with contents, for the disabled one. A. simple and ei'ective means is also provided for supplying lubricant to the top ot' thel jour.- nal, as well as below it, for the lubricant which is supplied to the top of the brass seeps through the 4packing within openings o and t, onto the journal, and to the space and packing below said journal, within the inner box. This results in the use of a less quantity of oil than when supplied only from below, as is the case in the present or- The inner box or containing member, under such a construction, is smaller than the ordinary journal box and more snugly surrounds the journal. This makes possible, not only a saving of oil, but a saving in the quantity of wool waste or other packing material used. rIhe ordinary journal box requires approximately an average of about twenty four ounces of waste, whereas under my construction both the upper and the lower space of the inner or removable containing box can be properly packed with not to exceed eight ounces of waste. A further advantage in my construction is th-e fact that this waste packing sons from removing waste from the ournal box for use in building fires, as is so often done from the ordinary type of journal box.

This, unless discovered in time, results in a hot box and perhaps damage. ln my construction, though the packing may be removed rom the lower part of the inner box, the packingabove the journal and out of reach from the outside, thoroughly lubricates the journal from above.

The inner box, in addition to containing the brass and the means for 'retaining lubricant therefor,

' also, by reason of its construction, forms an yeitfective dust guard about the axle to prevent the admission of dust and dirt to the Thus it will be understood ,that the present invention provides a coni. struction in journal boxes wherein an inner 1 or containing member with the brass, lubrijorni of the invention, I ani aware that changes in form, proportions, size, materials minor details may be made without .de-

' parting from the spirit of the invention, I and l do not limit the invention to the parz ticular showing made for purposes of illustration.
