WASTE GRAB PREVENTER AND LUBRICATING DEVICE Elum L. Yelverton, Laurel, Miss.

7 Claims.

This invention relates to a device which is ef fective for properly lubricating axles and simultaneously preventing waste grabs which cause hot'boxes particularly on railroad car axles.

In railroading terminology waste grabs occur when rotating journals operating in journal boxes carry small portions or chunks of cotton waste or lubricating packing upwardly to the bearing, usually brass bearings, which lodge between the bearing and the journal. When the chunks of packing are thus lodged, friction of the rotating journal will generate heat and ultimately the heat will ignite the packing in the journal box. Unless the burning packing is discovered, a hot box will result and generally the bearing is destroyed and the journal will be damaged. Hot boxes are very expensive in that destroyed bearings greatly damage the journal and in some cases have caused wrecks.

Previously different devices have been designed to lubricate axles on railroad cars. Also, different devices have been designed to prevent waste grabs. Generally, however, the different devices were not designed to accomplish the dual function of properly lubricating car axles and at the same time prevent waste grabs.

The main object of this invention is to provide a simple and practical device which will properly lubricate bearings and axles, and at the same time substantially eliminate waste grabs in journal boxes on railroad cars and other moving means of transportation involving similar structure.

Another object of this invention is to provide a device by means of which large amounts of lubricating packing can be saved, thus greatly reducing the cost of packing and lubricating journal boxes.

A further object of this invention is to provide a device which is clamped between the top of the bearing and the wedge or other part supporting the bearing in position thus permittinglongitudinal and transverse movements with the normal movements of the bearings, (ofttimes referred to as brass in railroad terminology) and assuring protection at all times to the bearing against waste grabs.

An additional object of this invention is to provide a device through which the lubricating material, as cotton waste, is held in such positionthat optimum lubricating value will be obtained between the bearing and the journal.

These and other objects, features and advantages of my waste grab preventer and lubricating device will appear from the following description, wherein reference is made to the accompanying sheet of drawings.

In the drawings,

Figure 1 is a perspective view of the waste grab preventer and lubricating device.

Figure 2 is a vertical section through a conventional journal box arrangement in a plane parallel to the journal axis, the journal being in elevation and the device illustrated in Figure 1 in section.

Figure 3 is a section taken in the plane of line 3-3 in Figure 2 illustrating the position of the waste grab preventer with reference to the journal, journal bearing and the packing.

Figure 4 is a fragmentary vertical section through a journal box in a plane parallel to the journal axis, showing the waste grab preventer in elevation with reference to conventional parts in a journal box arrangement, and

Figure 5 is a plan View of the waste grab preventer in elevation and positioned over the journal bearing and other conventional parts in a journal box.

Similar reference numerals refer to similar parts throughout the several figures and description.

In the drawing, I0 denotes a conventional journal box with a hinged cover I2 and an axle 14 extending into the box M. The journal [6 on axle l4 being of conventional design has a fillet l8 and collar or end flange 26. A conventional journal bearing 22 is positioned on journal [6, and the bearing 22 is held in position by means of the usual wedge 24. A suitable dust guard 26, is provided in the journal box. The bearing 22 is provided with cars 28.

The waste grab preventer and lubricating device 30 in its simple form as shown in the drawings, especially Figures 1, 2, and 3, comprises a frame, preferably sheet metal, with asubstantially fiat top 32, which is shaped to conform to the upper surface of bearing 22. The top 32 is gradually sloped downwardly and finally merges into parallel side walls 34, the lower portions of which are at substantial right angles to the top 32. The side walls 34 extend downwardly on each side of journal [6 to points about in line with or below the center line of the journal. Projected portions 36 which correspond to the shape of ears 28 of the bearing 22 are provided adjacent to the flat top 32.

Fastened to the lower or bottom edges of the side walls 34 is a foraminous material 38 which forms a loop between the side walls 34. The foraminous material is preferably fastened to the lower edges by crimping as shown at 39, although any means of fastening may be used. The ends of the foraminous material 40 and 42 extend beyond the ends of the frame side por tions as shown in Figure 1. In practice the end dB should extend about 2 to 4 inches beyond the frame, and end 42 should extend about 1 to 2 inches beyond the frame side portion. These extended end portions, viz. 4B and 42, serve a very useful purpose as illustrated in Fig, 2 and will be described more fully below. The foraminous material is preferably heavy canvas as for example about 10 ounce weight material, al-. through any weight canvas, webbing, o'r other foraminous material which will withstand hard wear may be used with satisfaction.

The waste grab preventer and lubricating de-, vice is positioned between the top of the bearing 22 and the wedge 24, and the looped forami-noiis material 38 is passed below the journal It. A suitable quantity of oil soaked lubricating packing 44, as for example, wool waste, cotton waste, etc., is then inserted into the journal box between the foraminous material 33 and the bottom of the journal box. As the lubricating packing material is inserted, the foraminous material is pushed upwardly in loose folds 45 against the lower; portion of journal 85 as illustrated in Figuresz and 3. Ihe extended end 48 of the foraminous material is then folded downwardly and positioned or tucked between the packing id and the bottom of the journal box as shown at 38. The extendedend d8 will fold itself into position against the fillet l8 and the dust guard 25 as s we at It is evident that since the foraminous material hold s the packing'in a confined area, no material can normally become lodged between the journal and the bearing. The oil contained in the packing material will soak through the foraminous material and thus lubricate the journal. The amount of packing material required to properly pack the journal box will be considerably less than is generally placed in journal boxesheretofore. Since the frame has ears 36 which clamp over ears 28 of the bearing as shown in Figure 5, the waste grab preventer will follow the lateral or any other movements which abearing makes when the car is travelling.

Having described and illustrated my invention in one of its embodiments, I claim as follows:

1 In combination with a journal box, a journal, a bearing, and a wedge positioned between the bearing and the upper portion of the journal box, a waste grab preventer and lubricating device which comprises a frame positioned betweenthe wedge and the bearing with the side portions thereof extending downwardly on each side of thejournal, foraminous material fastened to the bottom edges of the frame side portions and forming a loop below the journal andwith the ends of the foraminous material extending beyond the ends of the frame side portions, lubricating packing material positioned between the foraminous material and the bottom of the jourrial box thus forcing the foraminouslooped pore tionin folds against the lower part of the journal, and the extended ends of the foraminous mate'rial holding saidlubricating packing material in a compacted and confined area. i
