Improvements in Car-axle Boxes.
We, JAMES LAFYETTE KINSELL, and FENNER AUGUSTUS LEAVENS, both of
Belle Plaine, in the County of Benton, and State of Iowa, United States of
America, Gentlemen, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention has relation to car-axle boxes and among the objects sought to be
attained by said invention is to provide a car-axle box in which the tow or cotton
waste which is saturated with lubricating material is better retained against the
sides of the journal-end of the axle and brasses where the most friction occurs, and
also prevents it from falling or working to the bottom of the box, thus effecting
greater economy in its use.
A further object of the invention is to improve the box in the several details of
construction, and with the above and other objects in view,
The invention consists in the construction, arrangement and combination of parts
as hereinafter fully described, illustrated in the drawing and pointed out in the
appended claim.
In the accompanying drawing:
Fig. 1 represents a longitudinal vertical section of a car-axle box constructed in
accordance with our invention, the journal-end of the car-axle being shown in
position therein in full lines.
Fig. 2 represents a transverse section taken on line x-x of Fig. 1.
Fig. 3 a similar section taken on line y-y of Fig. 1.
Fig. 4 a horizontal section taken on line z-z of Fig. 3.
In the accompanying drawings, A represents the car-axle box and B the journal
end of the axle, said box having the usual hinged lid C and catch a, for retaining
it closed. The base or bottom of the box A is formed of just sufficient width
between its perpendicular sides e, to admit of the journal end of the axle passing
down between them. This width of the box or narrow base D, is maintained upon
both sides thereof to about on a line with the central diameter of the journal end
of the axle, as shown in Fig. 2. This however may be varied at pleasure and the
depth of the base D either increased or diminished. The opposite sides of the
box A are extended some distance out from the vertical walls of the base D or
have a swell or convexity to provide chambers E, which chambers extend the
entire length of the box upon both sides thereof for the reception of the tow or
cotton saturated with lubricating material as shown at d, Fig. 2. The chambers E
retain the tow or cotton-waste which is saturated with lubricating material against
the sides of the journal end of the axle and the brasses where the most friction
occurs, the tow or cotton waste with its lubricating material at all times being held
up in position and prevented from working or falling down into the bottom of the
box where it would not perform its office. The hinged lid C has a compressor F
upon its inner side so as to slightly compress the tow or cotton waste and hold it
back in place.
The inner end of the box has a recessed guide G in which are located suitable
coiled springs H which permit the lower bearing section 1 to fall with any down-
ward movements of the journal end of the axle. The bearing section I has a
semicircular bearing to receive the lower portion of the journal end of the axle and
the bearing section K has a similar formed bearing to extend over the upper

page_text: portion of the journal end of the axle, as shown on Fig. 3. The upper section K
is held down in position by its own weight, and the purpose of these sections is to
keep out the dirt and grit. The bearing sections I K, have rabbeted edges or
overlapping flanges to prevent any open space between them and thus effectually
excluding any dirt or grit.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A car-axle box having a narrow base and extended sides to form chambers
for the tow or cotton-waste with its lubricating material to hold and retain it
against the sides of the journal end of the axle, and a hinged lid having a com-
pressor upon its inner side to force said tow or cotton waste back in the box,
substantially as and for the purpose set forth.
2. A car-axle box having a recessed guide upon its inner end, coiled springs
located therein, and bearing sections for the journal end of the axle, said sections
having rabbeted or overlapping edges, substantially as and for the purpose
specified.
