TRUVIDIONAL DI MUTTALION.
Improvements in the Supporting Frames and Driving Gear of
Centrifugal Machines.
I, GIDEON POTT of the Firm of Pott, Cassels and Williamson, Engineers and
Founders, Motherwell in the-County of Lanark, do hereby declare the nature of
this invention, to be as follows:-
This invention relates to the construction of the frames for carrying the journal
bearings for the rotating spindles of Weston centrifugal machines, the object of the
improvements being to provide convenient means of encasing and guiding the
driving belts so that whilst rendering all parts of the driving gear accessible
the attendants working underneath the framing may not incur risk of injury.
To that end I construct the overhanging portion of the framing over which the
driving belts are carried of channel section or similar section so as to encase
the belts on both sides and underneath whilst the upper side may be open. The
portion of the framing under each belt is by preference of T-shape in plan, the
part on which the driving pulley is carried having an extended base. resting on
the ground or flooring and converging towards the upper end in an approximately
horizontal member of channel section wherein the belt from the driving pulley
passes to the pulley on the upright shaft of the centrifugal where the horizontal
member is supported by upright frames or standards carrying the bearings of the
said shaft.
The
When the framing for a battery or series of centrifugals is erected the heads or
ends of the T-shaped frames are made to abut and considerable space is left
between each of the horizontal channeled members in which the belts run to permit
of the attendant passing up to and reaching any part of the driving gear.
guide pulleys usually provided for guiding the driving belts are carried upon
short spindles dropped into bearings formed for them in the channeled portions of
the framing.

COMPLETE SPECIFICATION.
Improvements in the Supporting Frames and Driving Gear of
Centrifugal Machines.
I, GIDEON POTT, of the Firm of Pott, Cassels and Williamson, Engineers and
Founders, Motherwell, in the County of Lanark, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
lescribed and ascertained in and by the following statement:-
This invention relates to the construction of the frames for carrying Weston
centrifugal machines, the object of the improvements being to provide convenient
means of encasing and guiding the driving belts so that whilst rendering all parta
of the driving gear accessible the attendants working underneath the framing may
not incur risk of injury.
As shewn by the accompanying drawings in which Figure 1 is an elevation and
Figure 2 a plan of the improved apparatus I construct the overhanging portion A

page_text: of the framing A, A', over which the driving belt is carried of channel section or
similar section so as to encase the belt on both sides and underneath whilst the
upper side may be open. The portion A of the framing under each belt is by
preference of T-shape in plan, the part A' on which the driving pulley D is
carried having an extended base resting on the ground or flooring and converging
towards the upper end in an approximately horizontal member A of channel
section wherein the belt from the driving pulley D passes to the pulley E on the
upright shaft F of the centrifugal G where the horizontal member A is supported
by upright frames or standards C carrying the bearings of the said shaft F.
When the framing for a battery or series of centrifugals is erected the heads or
ends of the T-shaped frames are made to abut at B and considerable space is left
between each of the horizontal channeled members A. in which the belts run to
permit of the attendant passing up to and reaching any part of the driving gear.
Guide pulleys H are provided as usual for guiding the driving belts.
The machine is driven by means of a friction pulley I operated by a hand lever J
as usual in machines of this class.
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 :-
Supporting frames for the driving gear of centrifugal machines constructed and
arranged to encase the driving belts and provide for convenient access thereto,
substantially as described with reference to the annexed drawings.
Dated this 14th day of November 1894.
