PROVISIONAL SPECIFICATION.
Improvements in Roller Bearings.
I, GUSTAV ADOLPH FREERKS of Stubbenhukstr. 15-17 Hamburg, Germany,
do hereby declare the nature of this invention to be as follows:-
Roller bearings such as ordinarily used heretofore, in which the several rollers
are mounted on axles which are arranged in the bearing casing, are open to
objection because the bearing casing must be fitted with extreme accuracy, and the
insertion of the rollers is tedious and difficult.
These drawbacks are completely obviated in a roller bearing according to this
invention and which is illustrated in the accompanying drawings, whereof
Fig. 1 is a side elevation, the cover of the casing being removed, and
Fig. 2 a section on the line A-B of Fig. 1.
My roller bearing consists of a cylindrical casing a, a number of live or running
rollers e each provided in the middle with a groove, and an annular plate d which
holds the rollers in their relative positions.
For this latter purpose the plate d is provided at its periphery with notches or
recesses which embrace the reduced portions of the several rollers.
The advantage of this roller bearing consists in the fact that no special axles
are required for rollers, and the boring of the holes for the pins or journals in the
bearing casing can also be dispensed with. Furthermore the putting together and
taking apart of the bearing is considerably simplified, because the live or rumming
rollers need merely to be inserted into the middle plate d, and the whole can then
be placed into the casing.

COMPLETE SPECIFICATION.
Improvements in Roller Bearings.
I, GUSTAV ADOLPH FREERKS, of Stubbenhukstr. 15-17 Hamburg, 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 :-
Roller bearings such as ordinarily used in which the several rollers are mounted
on axles carried by a casing, are open to objection because the casing must be
constructed with extreme accuracy, and the insertion therein of the rollers is tedious
and difficult.
Now this invention has reference to a construction of roller bearing wherein
these drawbacks are completely obviated.
In the drawings filed with my Provisional Specification,
Fig. 1 is a side elevation, the cover of the casing being removed; and
Fig. 2 a section on the line A-B of Fig. 1 of a roller bearing constructed
according to this invention.
It comprises a cylindrical casing a; a number of live or running rollers c each
formed with a groove bat or near the centre of its width; and an annular or
centrally perforated plate d constructed to hold or retain the rollers in their proper
relative positions. For this latter purpose, the plate d is formed at its periphery
with suitably arranged notches or recesses which receive the reduced or turned
down portions of the several rollers.

page_text: One side of the casing a is made removable as shown to admit of the annular
plated with rollers c being readily placed within or removed from the casing.
Further-
The advantages of this construction of roller bearing consists in the fact that
no special axles are required for the rollers, and the bearing casing a does not
require to be bored to receive pins or journals for carrying the rollers.
more the putting together and taking apart of the bearing is considerably
simplified, because the live or running rollers need merely to be inserted into the
plated, and the whole can then be readily placed into the casing or removed
therefrom as required.
Having now particularly described and ascerta ned the nature of this inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
:-
T
1. A. roller bearing wherein the rollers are for ned each with a turned down
portion, and are held or retained in their proper relative positions by an annular or
centrally perforated plate formed with notches or recesses to receive the turned-
down portions of the rollers, the arrangement being such tliat the rollers can be
readily placed within or removed from the roller casing substantially as described.
2. My improved roller bearing constructed as described and shown.
Dated this 3rd day of August 1892.
