COMPLETE SPECIFICATION.
Improvements in Washer-like Packings for Railway Axle-box
Stuffing Boxes and the like.
I, FRANZ HAUSENBLAS, Manager, of 25, Eisenhammer Str., Augsburg, in the
Kingdom of Bavaria, Germany, 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 relates to improvements in washer-like packings for railway
stuffing boxes and the like, and has for its object the prevention of water or sand
passing into the stuffing box and further allows no leakage or waste of oil.
I will now proceed to fully describe the improved packing with reference to the
accompanying drawings in which
Figure 1 shews the improved packing applied to a stuffing box.
Figure 2 being a cross section along the line a-b of Figure 1.
Figure 3 a cross section following the line c-d of Figure 1 and
Figure 4 is an end view of the said packing and in the following description like
marks of reference indicate like parts.
This improved packing consists in a stiff solid plate P (see Figures 2 and 4) made
of tin, wood or other suitable inaterial upon which a soft felt plate F is fastened and
turned over at the edge.
When this felt plate F lies on the inner side of the back D of the stuffing box,
the neck shaped part surrounds the carriage axle A.
In order to obtain a regular and tight joint of the said felt plate, all round the
axle spring rings R are arranged which exert a radial pressure, thus compressing the
neck shaped part of plate F.
These rings may be of india rubber or made from steel wire or of any other
suitable material.
By this means any oil or dust will be excluded from the axle, a complete
tightening being thus obtained.
The pliability of the felt neck only allows of such friction on the axle as to prevent
it from getting hot.
Two bow-shaped flat springs ƒ ƒ are arranged upon the plate P both the ends of
which rest upon the plate, while on the other hand the bent parts of these springs
exert a pressure on the inner side G of the circular chambers of the stuffing
box.
By this means the plate P together with its felt lining F is uniformly and closely
pressed against the sides of the axle box, rendering it therefore dust and oil
tight.
It is only necessary to renew the felt plate when worn out, as all the other parts
can still be used, which is an important consideration.
The probable higher cost of the new appliance cannot be taken into account
considering the advantages obtained in obviating the possibility of the axle running
hot and in preventing waste of oil.
On the contrary considerable expense will be saved by making use of the
improved washer-like packing.

page_text: 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 :-
A washer-like packing for stuffing boxes, consisting of a stiff plate P lined with
felt or the like, the latter being bent upon the carriage axle and held there by
elastic rings R the tightening of the stuffing box being effected by flat springs f
which exert a pressure upon the inner side of the stuffing box-substantially as
described above and represented in the accompanying drawings.
