PROVISIONAL SPECIFICATION.
An Improved Portable Rotary Blower, Exhauster, or Pump.
I, ERNEST SAMUELSON of Banbury in the County of Oxon, Engineer do hereby
declare the nature of this invention to be as follows:-
The object of my invention is to provide a light form of portable rotary blower,
exhauster, or pump which can be easily transported by a man from any one position
to another, and the improvements consist in making the frame to which travelling
wheels and handles are attached an integral part of the machine, and for this purpose
I cast or otherwise secure to each of the end plates, or sides, of the casing of the
blower, exhauster, or pump, suitable brackets on to which an axle can be fastened so
as to carry a travelling wheel or wheels, and to which also the handles can be fixed
for transporting the machine.
Where the weight of the blower, exhauster, or pump is but light, and within the
carrying capacity of 2 men I add as an alternative suitable brackets, which can be
bolted to or cast on the end plates, or casing, of the blower, exhauster, or pump to
which can be attached long handles so as to enable 2 men to carry the machine
between them.

An Improved- Portable Rotary Blower, Exhauster, or Pump.
1, ERNEST SAMUELSON of Banbury in the County of Oxon, Engineer, do hereby
declare the nature of this invention and in what manner the same is to he performed,
to be particularly described and ascertained in and by the following statement:-
The object of my invention is to provide a light form of portable rotary blower,
exhauster or pump which can be easily transported by a man from any one position
to another, and the improvements consist in making the frame to which travelling
wheels and handles are attached an integral part of the machine, and for this
purpose I cast or otherwise secure to each of the end plates, or sides, of the casing
of the blower, exhauster, or pump, suitable brackets on to which handles can be fixed
for transporting the machine, and an axle can be fastened so as to carry a travelling
wheel or wheels. Where the weight of the blower, exhauster, or pump is but light,
and within the carrying capacity of 2 men, I add as an alternative suitable brackets
which can be bolted to or cast on the end plates, or casing, of the blower, exhauster,
or pump, to which can be attached long handles so as to enable 2 men to carry the
machine between them, and in order that my invention may be more clearly understood,
I give in
Fig. 1 side elevation of a blower, exhauster, or pump fitted with a pair of travelling
wheels and handles.
Fig. 2 shows front elevation of same

page_text: Fig. 3 a separate view of the end casing or casting of the blower, exhauster or
pump showing the attachment of the handles and axle for wheels.
Fig. 4 shows front elevation of same.
Figs. 5 and 6 show the same arrangement but with loose brackets for attaching the
handles to the sides of the casing, and
Figs. 7 to 10 show the arrangement of main axle fitted to fast, and loose, lugs on
side casing.
The same letters refer to the same parts in the different figures.
A is the blower, exhauster or pump, whilst B, B, are the ends or side castings
forming part of same.
C is an axle fitted with travelling wheels D, D, and is fastened to the handles E, E,
(which in the drawings are shown as being made of tubing, but I do not confine
myself to this shape of handle) by means of any suitable clips and bolts such as shown
in the drawing at F, F.
On the side casings B, B, are cast projections or lugs G, G, to which the
handles E, E, are bolted as shown in Figs. 3 and 4. Instead of these lugs forming
an integral part of the end casing B, I use as an alternative, loose brackets H, H, by
means of which the handles E, E, can be fixed to the side casing as shown in
Figs. 5 and 6.
Where the weight of the blower, exhauster, or pump is 'but light and within the
carrying capacity of 2 men, I extend the handles so as to project in the front of the
machine in a similar way to that in which they are shown in the drawing at the back
of ditto, and dispense with the main axle C and travelling wheels D, D, so that the
machine can be carried by 2 men, the handles forming a sort of "stretcher."
In either case I attach to the handles foot rests or supports K, K, so that the
machine will stand firmly on the ground whilst at work.
I do not confine myself to any particular form of blower, exhauster, or pump, but
in the drawings have shown the well known form of a Roots' blower.
The transport axle instead of being fixed on to the handles, may if desired, be
attached by means of lugs cast on the end casing, or other part of the blower,
exhauster, or pump, as in Figs. 7 and 8, or by means of loose brackets, as in the case
of the handles, as shown in Figs. 9 and 10.
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 :-
1. The combination of bandles attached to the casing of the blower, exhauster, or
pump, by means of projecting lugs cast on the end or other convenient portion of the
casing of same, or by means of loose brackets fixed thereto, together with a transport
axle and wheels fixed to the said handles, or to the end casing as shown and
described.
2. The combination of handles attached to the casing of the blower, exhauster or
pump, by means of projecting lugs cast on to the end or other convenient portion of
the casing of same, or fixed thereto by means of loose brackets.
