W. M. GEWIN JOURNAL WIPER Filed Sept. 22, 1944 Patented Mar. 21, 1950 UNITED STATES PATENTv OFFICE JOURNAL WIPER William M. Gewin, Dupo, Ill. Application September 22, 1944, Serial No. 555,229

This invention relates to a journal wiper, and concerns itself more particularly with journal Wipers adaptable for use in the journal boxes of railway rolling stock.

In the construction of railway cars, it is standard practice to extend the wheel axes into journal boxes in which the ends thereof, shaped in the form of journals, are enclosed. The journal box forms a housing for the journal and the bearing plate through which the weight of the car is transmitted to the axle. The lower part of this box provides a well in which lubricants are contained and in which waste material is inserted as a wick for carrying 011 from the well to the under surface of the journal. 'Due to the construction of these boxes, it is impossible to keep them free from dirt, grit, and other foreign bodies which enter into the oil and are carried up and in between the journal and its bearing. The Journals are thus inherently subject to bearing failures duev to the abrasive effects of such foreign material. They are also subject to a condition known to the railroad art as "waste grab," which is caused by the journal's carrying the waste from thebottom of the box up to and in between the journal surfaces and the bearing. In this restricted position, the oil is soon worn from the waste, and the latter forms a hard carbon-like deposit on the bearing surface which ultimately results in a bearing failure. Both of these conditions prevent proper lubrication of the cars Journals, and cause "hot boxes."

It is known that many waste-retaining devices and Journal wipers have been proposed to overcome the aforesaid difficulties, but, for the most part, they have had limited success due to the fact that their installation is complex and requires some operation upon the journal, waste or the device itself for their mounting. In the present invention, it was found possible to perfeet a wiper which sacrifices none of its quality performance in preventing grit and waste from reaching the journal bearing at the expense of being readily mountable. On the contrary, the location of the blades of this wiper insures adequate protection for, and the proper lubrication oi, the bearing, and its simplicity of construction makes it possible to install the same on any standard Journal by simply opening the journal box lid and slipping the wiper into position on the journal.

Accordingly, it is the principal aim of this invention to provide a journal wiper which is positive in its action and which may be easily installed on, or removed from, a journal.

8 Claims. (Cl. 30889) It is also an object of the invention to provide a journal wiper, meeting the foregoing requirements and possessing those advantages, which is of simple design and which is economical to construct.

A specific object of the invention is to provide a Journal wiper having a pair of wiping blades adapted to be inserted into the box to lie against opposite sides of the Journal above a horizontal diameter therethrough, and a separate spring cllamping means to hold the blades resiliently in p ace.

Other objects and advantages of the invention will become apparent as the description proceeds.

In carrying out the invention in its preferred form, a pair of longitudinally extending wiper blades is arranged to be pressed against the journals surface at points above its horizontal diameter and adjacent to the bearing plate. These blades, which occupy positions on opposite sides of the journal, are held in" place and urged into engagement with the journal by means of a yieldable member in the form of a U-shaped spring disengageably connected to the blades. Portions of this spring are also fashioned into loops or hooks that fit around the lugs of the bearing plate and hold the entire wiper assembly in position.

A more comprehensive understanding of the invention willbe afforded from the following detailed description when considered in conjunction with the accompanying drawing, in which like reference numerals have been used throughout to designate like parts, and in which:

Figs. 1 and 2 are a side and end view, respectively, of a wiper blade employed in the present invention;

Figs. 3 and 4 are a plan and side view, respectively, of the yieldable member used to hold the wiper blades in place and into engagement with a Journal on which the wiper is mounted;

Figs. 5 and 6 are, respectively, a plan and side view of a Journal and bearing plate assembly showing the improved wiper mounted thereon;

Fig. '1 is an end view of said journal and bearing plate assembly, partly in section, further illustrating the position and manner of mounting the wiper; and

Fig. 8 is a detailed view illustrating the disengageable connection between the blades and the yieldable member of the wiper.

As illustrated in Figs. 1-4 of the drawing, the improved wiper consists of two wiper blades ll, taking the form illustrated in Figs. 1 and 2, and

a-single yieldable member 1 2, shown in Figs. 3 and 4, which is employed to hold the blades H in place against the journal as viewed in Fig. 7. The blades H are formed of suitable metal and are suflicient in length to extend the full dimension of the journal. They are shaped to present to the journal surface a bearing edge It and a wiping edge ll. Each blade is provided with a notch-l5 in which the lips l6 of the member [2 are insertable for holding the blades in their respective places with reference to the journal.

The member i2 is formed from a single length of spring steel and takes the form of a U-shaped spring, as illustrated in Fig. 3. It will be noted, Fig. 4, that this member is bent to form the arms I! and I8 which support the wiper blades II in position. The end section of member I2 is so formed as to pass around the end of the journal. It carries a wearing plate l9 which is centrally located thereon whose function will be discussed later.

As previously stated, the arms [1 and I8 of the member l2 are bent to form the lips l6, which, in turn, enter into the notches I5 of the blades I I, as illustrated in detail in Fig. 8. The continuations of the end sections of the wire forming the arms I l and 88 are then bent underneath these arms and extend longitudinally thereof to a point intermediate their ends and the base of the U. Here they are turned outwardly, bent vertically upward, and thence horizontally to form the loops or hooks 2| and 22.

When mounted on a journal and bearing plate assembly, the wiper occupies a position with respect thereto, as shown in Figs. 5 and 6. With particular reference to Fig. 6, it will be noted that the blade I i extends the length of the journal and occupies a position immediately underneath the lower surface 23 of the bearing plate or brass 24. The yieldable member l2, which supports the blades Ii, occupies a position with respect to these blades which is substantially in a plane common thereto. Its respective arms ll and i8 engage the blades II at the notch l5, as previously described; and the hook sections 2! and 22 thereof encompass the

bearing plate lugs

25 and 25, respectively. This method of mounting holds the blades II in place and the spring action of the member l2 urges them into contact with the journal 21 in a manner such that the respective wiping surfaces 14 of the blades ll prevent any grit or foreign matter from reaching the surface 28 (Fig. 7), common to the journal 21 and the babbited surface of the bearing plate 24. The presence of the blades II also eliminates any possibility of waste being carried into this space, and at the same time allows more waste to be in contact with the journal, resulting in better lubrication.

The journal wiper assembly comprehended in the above described and preferred embodiment is capable of being installed without any operation on the journal, such as jacking up the bearing plate from the journal or-taking the oil and waste out of the box. Here, by the simple expediency of opening the journal box lid (not shown), the blades H are positioned and held with one hand directly underneath the overhanging edges 23 of the bearing plate 2i, and the yieldable member I2 is carried over the end of the journal in a manner such that the lips it are engaged in the notches l5 of the plates. The yieldable member is pushed rearwardly until the hook sections 2 l-22 clasp the bearing plate lugs 25 and 2G and anchors the entire assembly in fixed position. The wear- 4 ing plate I9, which is carried on the yieldable member and frictionally held in place, is then pressed against the end of the journal 21 to prevent any part of the member l2 from coming in contact with the rotating journal where it would be subject to wear.

It is a distinctive feature of this invention that it is constructed so as to be separable into three parts, which makes installation possible without disassembly of the journal parts, and also provides for replacement individually of worn parts, although certain features of this invention are applicable to a unitary wiper device wherein all three parts are permanently joined.

While it is not intended to limit the invention to the use of any particular material or to any specific size or dimension of any component part thereof, it has been found in successfully practicing the invention that the blades It may be made from 18 gauge sheet brass, and the spring member i2, from it inch round steel.

As many modifications of the invention are possible without departing from the scope thereof, it is to be understood that the description and illustrations herein made are for the purpose of presenting an embodiment of the invention only and are not to be considered in a limiting sense.
