JOURNAL BOX PACKING Charles T. Ripley, Wilmette, Ill. Application January 25, 1935, Serial No. 3,433

I V 1 can... (o1. 30888) This invention relates to a new and improved journal box packing, more particularly to an improved form of packing material or packing units, and the method of using same within a car journal box in order to supply lubricant to the journal.

,face of the rotating journal thus maintaining the requisite film of oil between the upper side of the journal and the brass which supports the box and the load carried thereby.

There are several objections to this form and method of packing, the most serious fault being the frequent occurrence of waste-grabs, that is small fluffy particles of the waste material are carried up'by one side of the rotating journal and eventually some of this material finds its way between the journal and the brass and breaks down the oil film,'often resulting in the burning out of the bearing and other serious damage.

v,JAccording to the present invention, the oilcarrying material, the waste with the springs embedded therein, is enclosed in an envelope or bag (or a plurality or series of envelopes) of flexible fabric which is porous to allow the passage of oil therethrough but is of fine enough texture, that is without large openings, so that it will effectively hold the waste. The oil is transmitted through this envelope to the journal, but the fine particles of the waste are confined and do not ride up on the journal, thus eliminating the principal source of waste-grabs. The springs keep the waste open and loose against matting and in contact with the upper surface of the envelope and the envelope in contact with the journal. This form of packing has numerous other advantages as will be brought out hereinafter.

The principal object of this invention is to provide an improved journal box packing of the type briefly described hereinabove and disclosed more in detail in the specifications which follow.

Other objects and advantages of this invention will be more apparent from the following detailed description of one approved form of packing and the method of using same according to the prim ciples of this invention.

In the accompanying drawing:

Fig. 1 is a longitudinal vertical section through a standard type of railway car journal box with the improved packing used therein.

Fig. 2 is a transverse vertical section, taken substantially on the line 2-2 of Fig. 1. 5'"

Fig. 3 is a perspective view of one of the improved packing units. l

Fig. 4- is a perspective view, on a smaller scale, of 'a modified form of packing.

Referring first to Figs. 1 and 2, the car journal-box l encloses the wedge 2 and brass 3 which rests upon the upper surface of rotating journal 4 formed at the end of car axle 5 which projects into the rear end of box I through opening 6.

The dust-guard l positioned in pocket 8 in the rear wall of the box tends to exclude dust and minimize the escape of oil. The opening 9 in the front end of the box through which packing and lubricant are inserted is normally closed by the lid 16 pivoted to the box at H. 20

All of the above is an example of standard construction. Ordinarily the bearing is packed or lubricated by opening the lid I0 and tamping a quantity of loose cotton or wool waste into the space between the bottom of the box and the journal 4. This waste, is soaked with oil both before and after its insertion into the box, and additional oil may beadded whenever required. Ordinarily a twisted roll of this waste material, known as a back roll, will first be pushed into place at the rear wall of the box to seal this opening, and after a sufiicient quantity of the loose waste has been pushed into place beneath the journal, another compacted mass of the waste known as the front plug is often pushed into place at the front of the box. This type of packing is fairly efiicient as far as lubrication is concerned, but it has certain faults among which is the frequency of waste grabs referred to here inabove. In order to minimize this evil, it has been necessary to use a fine quality of selected waste from which all of the. finer fiufi'y portions, more apt to be carried up by the rotating journal, have been picked or eliminated, and this greatly increases the cost of the waste material.

According to the present invention, a mass of the loose oil-absorbing material is confined in a flexible fabric bag or envelope so as to form a freely pliant pillow such as shown for example in Fig. 3. In use, a plurality of these units will be used to pack one box, three being shown by way of example in Fig. 1.

The filling or packing material may be cotton or wool waste as indicated at l2 (Fig. 1) and spring inserts l3 or any other suitable resilient 5 through but will not permit any strands of waste 7 devices are embedded in and distributed as uniformly as possible through the waste for the purposes above mentioned. No particular type of packing material is essential to the present invention, in fact much cheaper grades of waste may be used than has heretofore been the practice since this waste material is effectively confined and cannot find its way between the journal, and brass. This mass ofwaste is confined loosely in a bag or envelope 14 of some suitable cloth fabric suificiently porous or open in its'textureor mesh so that it will be adapted to absorb oil or freely permit the passage of oil thereor lint to pass through it. The bag or envelope is sewed orotherwise secured together, in any desired manner, preferably so as not to expose seams or fastening means at the sides more apt to come in contact with the journal. need have no definite form, in fact it is fairly shapeless and pliant so that it may be easily forced into the space beneath the journal. One of these completed units resembles a pillow in its gerieral,1f0rm, and also in its qualities of pliancy and resiliency.

:These units or pillows are usually soaked with oil and then drained so thatthey will be saturated with the lubricant before insertion in the journal box. The units are inserted, one by one, through the front box opening 9, preferably with the longer dimension'of the bag extending transversely of the box, and then pushed into position between the bottom of thebox and the journal as indicated in Figs. 1 and. 2. Preferably the units Will be of such size that some certain number (for example three) will be sufficient to properly pack a'standard car journal box.

7 necessity of providing a separate back roll or front plug, since the functions of these are per-' formed by the rear and'front pillows or units bags can be disarranged or pushed into position so as to present new surfaces to therotating journal.

If desired, a plurality of these bags or units,

(enough to pack one journal-box). can be linked .together 'as a chain or series as shown in Fig.

4. A single long bag can be tied at intermediate points l5 and I6 to form a chain of three :bags

There is. no

or links l1, l8 and IS. The links or units of this chain are successively forced into position within the journal-box by bending the series alternatively in opposite directions at the joints I6 and I5, in an obvious manner. 5 V

In time, the surface of the bag or envelope may wear through, but the enclosed waste material may be reclaimed. If a bag should wear through vantages over the standard method of packing 15 with loose waste, among which may be mentioned the'followingi The elimination of waste grabs.

These standard packing units are easier to handleand insert in the box than loose unconfinedwaste. I

-I claim:

In combination with a journal and journal box:

a packing comprising a plurality of unitseach 3 consisting of a mass of fibrous, oil absorbent} material; a flexible envelope porous and permeable .to. oil but of a texture tohold the fibrous material and preventothe strands thereof from escaping from the envelope; anda plurality of metallic springs; said units, being arranged under the journal transversely thereof with their ends, extending upwardly between the sides "of the journal box and the journal andso thatthe packing substantially fills the space between the bot-. tom and sides of the journal box and the portion of the journal'below its center and fits closely andcontinuously around the underside of the journal and said springs being embedded in and distributed with substantial uniformity through- 453 out the fibrous material so as to keep the mate.-

rial open and loose against matting and ex! pandedin contact withthe envelope, and so as to keep the envelope pressed with substantial uni- V 'formity against the journal. 7 3
