Improvements in Securing Shaft Bearings to the Frames of
Machinery.
I, ALFRED SOAMES, of 16, Red Lion Street, Clerkenwell, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:--
The object of this invention is to provide a means for securing shaft bearings to
the frame of a machine truly in line with one another without planing or fitting
the parts and is applicable especially for securing to the ends of the frame of a dynamo
electric machine the bearings in which the armature shaft is to revolve.
To effect this I secure the bush of each bearing within a hollow boss forming part
of a bracket which is to carry it by running type metal into a space between the bush
and the interior of the boss whilst the bush is held in proper position by the shaft
passing through it. The bracket arms which extend from the boss I secure by bolts
to blocks or bushes secured within recesses in the frame by running type metal between
them this allows of the brackets being at any time removed and again replaced
accurately in position. The blocks or bushes when bolted up to the bracket arms
three equidistant arms being used by preference would be secured first to the frame
by running type metal around them whilst the bracket was held in proper position
relatively to the frame in any suitable manner. After both end brackets had thus
been secured to the frame the bearing bushes would be secured within the hollow
central bosses of the brackets.
To do this the bushes would be placed on to the shaft and the bushes inserted into
the bracket bosses-one of the brackets being taken off and afterwards replaced to
allow of this. Type metal would then be run into the spaces between the bush bearings
and the bosses and so soon as the metal sets, the two bushes would be held securely
and truly in line with one another.
Projections or recesses are formed in the parts between which the metal is cast so
that when the metal has set the casting holds both parts together.

Improvements in Securing Shaft Bearings to the Frames of
Machinery.
I, ALFRED SOAMES, of 16, Red Lion Street, Clerkenwell, in the City of London,
Engineer, 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 :-
The object of this invention is to provide a means for readily securina shaft

page_text: bearings to the frame of a machine truly in line with one another without planing
or fitting the heavy main body of the frame of such machine and is applicable
especially for securing to the ends of the frame of a dynamo electric machine the
bearings in which the armature shaft is to revolve.
To effect this I secure the bush of each bearing within a hollow boss forming part
of a bracket which is to carry it. The bush is held in proper position by the shaft
passing through it. The bracket arms I secure by bolts to blocks or bushes secured
within the frane by running type metal between them this allows of the brackets
being at any time removed and again replaced accurately in position.
Projections or recesses are formed in the parts between which the metal is cast so
that when the metal has set the casting holds both parts together.
My invention is illustrated by the drawings annexed which shew it as applied to
the frame of a dynamo electric motor.
Figure 1 is a side elevation one half in section of the frame.
Figure 2 is an end view of the same.
A is the heavy main body of the frame.
B B are the end brackets for carrying the shaft bearings.
CC are ring shaped blocks or bushes secured within the frame by type metal D
run in between them.
Preferably the outer ends of the bracket arms are as shewn in the drawings all
connected by a complete ring which fits to the ring shaped block or bush C, and
is secured to it by screw bolts.
In the construction shewn in the drawings the ring shaped blocks or bushes C
serve not only for carrying the end brackets as above described but also serve to
hold in position an assemblage of soft iron rings E (used for carrying the field
windings of the motor) in a manner similar to that described in the specification
of a former patent granted to me No. 117017 but the ring shaped blocks need not
necessarily serve this double purpose.
The parts are put together in the following manner. The rings E are mounted
side by side on a mandril as described in my former patent.
The brackets B bolted to the blocks or bushes C are placed on to the axes of
the mandril so as to hold the rings E between them. The parts so held together
are placed within the main body A of the frame and are supported temporarily
in proper position within it. The type metal casting D is then run in and holds
the parts together. When the parts have so been secured together one of the
end brackets can be taken off, the mandril with its axis can be removed and an
axis carrying the armature can be put into place.
In place of forming the castings D of type metal they might be of other
suitable material.
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 dynamo electric or other machine in which the bearings for a shaft are carried
by brackets held by bolts to blocks or bushes secured to the frame by castings of type
metal or other suitable material substantially as described.
