Improvements in Adjustable Ball Bearings for Carriage Axles.
We ROBERT LIEBSCHER and HERMANN KUNATH both of 8 Concordien Strasse
Dresden N. Germany manufacturers 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 adjustable ball bearings for carriage axles and has for
its purpose that the axle-box may be removed from the spindle without the balls
falling out and that the cone by which the balls are regulated is prevented. from
accidentally tightening on the balls and preventing them 'revolving.
In order to make our invention more clear we refer to the accompanying sheet
of drawings in which similar letters denote similar parts throughout the different
figures.
Fig. 1 is a longitudinal section of our improved axle-box.
Fig. 2 is a cross section through the line y fig. 1.
Fig. 3 is a view showing on a larger scale the bearing of the balls and the rings
for holding them in their place when the box is removed from the end of the axle-
spindle.
Fig. 4 shows a side view of the manner in which the regulating cones are held
fast.
Fig. 5 is an end view of figure 4.
A is the spindle which is screwed at its outer end and has a butting-ring S at the
inner end; the butting-ring S is provided with an oil hole s.
B is the axle-box on which the carriage wheel is fastened.
The axle-spindle A is fitted with the cone c¹ at the front, which is screwed on, and
at the back side with the cone c which abutts against the butting-ring S and is
prevented from turning by the pin t.
In the box B are fitted the rings e e¹ at the front and back side and held in their
proper positions by the rings m m¹. The rings e e¹ are so formed, that they encircle
the balls d to a certain extent, as may be seen by reference to figure 3.
The rings e which carry the balls d are made from hard steel while the rings e¹
which hold the balls d in the rings e are made from wrought iron. The rings hold

page_text: the balls d in such a manner, that when the axle-box is removed from the axle-spindle
the balls cannot fall out.
The inner end of the axle-spindle is provided with a lubricating groove s¹ and the
butting-ring S with the oil hole s which is closed by the screw ; the groove s¹
extends to the inside of the axle-box B.
Between the butting-ring S and the ball rings e e¹ are leather washers i fitted
which shut the axle-box completely at the back side.
The adjustment and fastening of the out side cone c¹ is as follows
The cone c¹ is screwed on to the front part of the axle-spindle A. The end of the
spindle is flattened on one side as seen in figs. 4 and 5 and a washer fitted over the
same this washer f is made from some soft metal as brass or bronze. The washer f
is prevented from turning by the flat on the end of the spindle, and is pressed
against the serrated end of the cone c¹. In front of the washer f is a lock-nut g
screwed on the end of the spindle, which presses the soft washer against the serrated
end of the cone c¹ and prevents the same from accidentally turning. The spindle is
fitted with a linch-pin ½ in front of the lock-nut in order to prevent the nut
coming off.
from
The end of the spindle is protected by the cap which screws-into the axle-box B.
The bearings may be easily adjusted by removing the cap and loosening the nut g
and washer f, when the cone c¹ may be adjusted at pleasure by a wrench; the end of
the cone is provided with squares for this purpose, and the washer and nut 9 again
tightened up.
•
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be perfornied, we declare that what we
claim is : •
1). In adjustable ball bearings for carriage axles the use of rings so formed that
“the balls cannot fall out when the axle-box is removed froin the spindle..
2) In adjustable ball-bearings for carriage axles the combination of the rings e ele e¹
and balls d with the cones c c¹, axle-spindle A and axle-box B; substantially and for
mothe purpose as described.
isd3) In adjustable ball-bearings for carriage axles, the combination of the rings e e e e¹,
incones crc, axle-spindle, A, washer f, lock-nut g and box B with cap k, substantially
and for the purpose as described.
1994) In-cadjustable ball-bearings for carriage axles, the combination of the axle-
spindle A, butting-ring S, cones cc¹, rings e e¹, leather-washers, soft metal washer, f
lock-nut balls d, axle-box B and cap k, substantially and for the purpose as
described.
