PROVISIONAL SPECIFICATION.
Improvements in and connected with Packings for Car Axle Boxes.
A communication from abroad by NIKOLAUS FRANTZ, of Sulzbach, in the Empire
of Germany.
I, KENNETH LESLIE SKINNER, of 41 Ambler Road, Finsbury Park, in the
County of Middlesex, Clerk, do hereby declare the nature of this invention_to be
as follows:-
This invention is specially though not exclusively applicable to the axle boxes of
colliery trucks and others which are likely to be frequently reversed or turned on
their sides. By the employment of this invention the lubricant is retained within
its chamber.
In carrying this invention into effect the axle boxes are provided with suitable
cups or recesses for containing the packing devices hereinafter to be described.
In the accompanying sheet of drawings there are shown, by way of types or
examples, several ways of practising this invention.
Figure 1 shows a form of the invention in which the packing consists of an
annular closed sleeve of leather, india-rubber or the like or of an open sleeve having
abutting joints. The steel spring d presses the outer portion of the sleeve against
the inner wall of the cup or recess, while the spring e presses the inner portion of
the sleeve against the axle.
Figure 2 shows a form in which the leather sleeve is pressed by the cap a and
the ring g against the bottom of the recess and by the spring h, as in Figure 1,
against the axle.
In Figure 3 the sleeve is filled with hemp or wick or with another soft material.
This packing material is compressed by the cap and the ring g, so that the sleeve is
pressed against the wall of the recess and the axle.
Figure 4 shows a form without a sleeve. The packing material consisting of
wire cloth or india-rubber discs or of any other soft material is compressed by the
cap in the ordinary manner.
In Figure 5 are shown several india-rubber discs having between them discs of
sheet metal pressed by a spring arranged behind the shoulders x, x¹ against the
bottom of the recess and the axle.
In Figure 6 a closed flexible air tube is inserted and in order to prevent
displacement the cup is tapered towards the mouth.
In Figure 7 the flexible tube is pressed by means of a spring arranged behind
the shoulder against the axle and the wall of the cup.
Figure 8 shows a wheel mounted loosely on a fixed shaft. In this construction
each of the packings shown in the Figures 1 to 7 of the accompanying drawings
may be employed.
It will be seen that a perfectly tight packing is secured and that the lubricant is
retained in position in whatever position the truck may be.
Dated this 20th day of February 1894.

J, KENNETH LESLIE SKINNER, of 5 North Road, Highgate, in the County
of Middlesex, formerly of 41 Ambler Road, Finsbury Park, in the County of
Middlesex, Clerk, 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 is specially though not exclusively applicable to the axle boxes of
colliery trucks and others which are likely to be frequently reversed or turned on
their sides. By the employment of this invention the lubricant is retained within
its chamber.
In carrying this invention into effect the axle boxes are provided with suitable
cups or recesses for containing the packing devices hereinafter to be described.
In the sheet of drawings left with the Provisional Specification there are shown,
by way of types or examples, several ways of practising this invention.
Figure 1 shows a form of the invention in which the packing consists of an
annular closed sleeve of leather, india-rubber or the like or of an open sleeve having
abutting joints. The steel spring d presses the outer portion of the sleeve against
the inner wall of the cup or recess, while the spring e presses the inner portion of
the sleeve against the axle.
Figure 2 shows a form in which the leather sleeve is pressed by the cap a and
the ring g against the bottom of the recess and by the spring h, as in Figure 1
against the axle.
In Figure 3 the sleeve is filled with hemp or wick or with other soft material.
This packing material is compressed by the cap and the ring g, so that the sleeve is
pressed against the wall of the recess and the axle.
Figure 4 shows a form without a sleeve. The packing material consisting of
wire cloth or india-rubber discs or of any other soft material is compressed by the
cap in the ordinary manner.
In Figure 5 are shown several india-rubber discs having between them discs of
sheet metal pressed by a spring arranged behind the shoulders x, x¹ against the
bottom of the recess and the axle.
In Figure 6 a closed flexible air tube is inserted and in order to prevent
displacement the cup is tapered towards the mouth.
In Figure 7 the flexible tube is pressed by means of a spring arranged behind
the shoulder against the axle and the wall of the cup.
Figure 8 shows a wheel mounted loosely on a fixed shaft. In this construction
each of the packings shown in the Figures 1 to 7 of the accompanying drawings
may be employed.
It will be seen that a perfectly tight packing is secured and that the lubricant is
retained in position in whatever position the truck may be.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvement in packing for car axle boxes for sets of wheels substantially
as set forth with reference to Figure 1.
2. The improvement in packing for car axle boxes for sets of wheels substantially
as set forth with reference to Figure 2.
3. The improvement in packing for car axle boxes for sets of wheels substantially
as set forth with reference to Figure 3.

5. The improvement in packing for car axle boxes for sets of wheels substantially
as set forth with reference to Figure 5.

The-improvement-in-packing-for car axle-boxes-for-sets-of-wheels-substantially-
as set forth with reference to Figure 6.
7. The improvement in packing for car axle boxes for sets of wheels substantially
as set forth with reference to Figure 7.
8. The improvement in and connected with packings for car axle boxes consisting
of the combination of a lubricating chamber adapted for a set of wheels with the
several packings shown in Figures 1, 2, 3, 4, 5, 6, and 7 respectively.
9. The improvement in and connected with packings for car axle boxes consisting
in the combination of the means shown in Figure 8 for directly lubricating the nave
of the wheel with the respective packings shown in Figures 1, 2, 3, 4, 5, 6 and 7
respectively.
