IMPROVEMENTS IN BEARINGS FOR SHAFTS OR AXLES
Year: 1885

page_text: I, HERBERT JOHN HADDAN, of 67; Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of said invention for IMPROVEMENTS
IN BEARINGS FOR SHAFTS OR AXLES, a communication to me from abroad by
A. W. Spatzier, of 18, Katharinenstrasse, Leipzig, in the kingdom of Saxony, to
be as follows :-
This invention has for its object to render axle-bearings more completely
adjustable, so that the same bearing may be used for axles of various diameters,
and for supporting the axles at various distances from the base of the bearing,
which may be a pedestal, a wall-bracket or a hanger.
For this purpose the wearing surface of the bearing: formed by the circumference
of rollers distributed around the axle and made adjustable radially by means of
screws.
There are preferably four cylindrical rollers distributed equally around the axle
and placed parallel with the same. The axle of each roller may be supported by
a forked bearing guided in a pair of slots placed radially to the main axle, and held
in position by a screw spindle made adjustable in the main bracket, so as to place
the roller at various distances from the opposite roller, and at various distances
from the base of the main bearing.

I, HERBERT JOHN HADDAN, of 67, Strand, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to
me from abroad by A. W. Spatzier, of 18 Katharinenstrasse, Leipzig, in the
Kingdom of Saxony and in what mauner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The axle-bearings, hitherto in use, require a bore exactly fitting the diameter of
the axle. This inconvenience is removed by so arranging the bearings, that the
contact-surfaces can be shifted according to the thickness or diameter of the axle.
Besides it will be advantageous for the erection of the bearings to render the
middle or axis of the same adjustable. To attain this double purpose, friction
roller bearings are employed some of which are shewn in the accompanying
drawings.
In the frame A, which may be constructed as a hanger, pedestal or wall bearing,
the bearing surface discs B are so lodged, that they can be shifted with their
bearings a along the slots b. The adjustment is effected by means of screws C, and
the slots may be provided with graduated scales to facilitate the accurate adjust-
inent of the running discs.
The latter are adapted to receive and guide the smallest axle and afford a
considerable variation for the diameter of the axle to be guided and supported.
The character of the running discs does not require a particularly clean polishing
or dressing of the contact surface of the axle or shaft, but it suffices to simply
insert straightened and smoothed axles.
The present construction shows the obvious advantage, that it is not necessary to
employ different models for different axle-diameters; also the effective height of
the bearing can be varied according to requirement, as by suitable displacement of
the running discs the middle of the bearing can be shifted.
Figs. 2, 3 and 4 of the drawing show a wall bracket A, in which the two upper
friction rollers are adapted for simultaneous adjustment by means of a yoke and a
screw spindle C, but the bearings of the upper friction discs may be rendered
adjustable independently of each other.
In Figs. 2, 3 and 4 the distance of the axle from the wall or base of the bracket
is constant, but it is easy to see, how it can be varied by rendering one or more of
the roller axles adjustable to and from the base of the bracket.
In Fig. 5 the bearings of the friction rollers are rendered adjustable up and down
along their slotted base plates D and E, and are secured by screw bolts d and c.
Fig. 1. shows the application of my invention to the crank-shaft of a steam
engine.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare, that what
I claim, is:
1.) An axle-bearing having wearing surfaces formed by the circumference of
friction rollers, one or more of which is or are rendered adjustable, substantially as
and for the purpose described.
2.) An axle bearing having wearing surfaces formed by the circumference of
rollers rendered adjustable separately or in pairs by means of screw spindles,
substantially as and for the purpose described.
