Improvements in Air Motors.
I, CARP TAMANZEFF of 45 Tscherkassky Pereoulok Moscow, in the Empire of
Russia do hereby declare the nature of this Invention to be as follows:-
According to my Invention a motor is driven by the action of a hot current of air
which rising from the chamber A into the chimney 6 actuates a fan wheel C placed
in its path. The wheel is composed of fans similar to those of an ordinary ventilator.
Each fan is made half of wooden planks c¹ and half of copper wire gauze c²
(Figures 2 and 4). The fans of the wheel C are helically arranged as in an ordinary
ventilator.
In the arrangement shown in Figures 1 and 2 the axle is vertical and is held in
position by horizontal beams d d the ends of which are fixed in the walls of the
chamber A or are supported by pillars arranged near to the inner walls of the
chamber A. The beams d are prevented from sagging by the brackets f.
The axle g carries at its lower end a toothed wheel which gears with the
wheel h¹ fixed upon the shaft i. This latter being provided with pulleys or other
means of transmission serves to transmit motion to the different mechanisms.
k
The axle g is supported in a bearing provided with balls to reduce friction. The
other bearings are also provided with balls.
For disconnecting, the shaft i is provided with a coupling sleeve l. All motion
may be prevented by closing the register m.
Above and below the wheel C, the axle carries flies n n1. The fly n¹ is
composed of hinged rods provided with weights at their ends as in centrifugal
governors.
Above the chamber A is a chimney b high enough to produce a strong draught.
The air contained in the chamber A may be heated by special furnaces arranged
near to it or by the waste heat of boiler furnaces or dryers. The air is also
heated by iron or cast iron pipes Q fed with steam derived from boilers or steam
engines.
To obtain a uniform temperature as well as to assist the up draught of the air, the
shaft i is provided with smaller ventilating fan-wheels *².
Figure 2 shews this arrangement in plan partly in section on the line I-II of
Figure 1.
In the arrangement shewn in Figure 3 the wheel C is fixed upon a horizontal
axle g and transmits motion directly to the pulley S. The hot air is led by a tube p
from furnaces placed in proximity.
In order to regulate the speed of the wheel C the axle g is connected by suitable
gearing to the shaft k¹ of a centrifugal governor whose sleeve acts upon a register 1.
This arrangement is also applicable to the machine shown in Figure 1.

Improvements in Air Motors.
I, CARP TAMANZEFF, of 45 Tscherkassky Pereoulok, Moscow, in the Empire of
Russia, 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 :-
According to my invention (referring to the drawings left with the Provisional
Specification) a motor is driven by the action of a hot current of air which rising
from the chamber A into the chimney b actuates a fan wheel C placed in its path.
The wheel is composed of fans similar to those of an ordinary ventilator. Each fan
is made half of wooden planks c¹ and half of copper wire guaze c² (Figures 2 and 4).
The fans of the wheel C are helically arranged as in an ordinary ventilator.
In the arrangement shown in Figures 1 and 2 the axle g is vertical and is held in
position by horizontal beams d d the ends of which are fixed in the walls of the
chamber A or are supported by pillars arranged near to the inner walls of the
chamber A. The beains d are prevented from sagging by the brackets f.
The axle g carries at its lower end a toothed wheel h which gears with the wheel h¹
fixed upon the shaft i. This latter being provided with pulleys or other means of
transmission serves to transmit motion to the different mechanisms.
The axle g is supported in a bearing k provided with balls to reduce friction. The
other bearings are also provided with balls.
For disconnecting, the shaft i is provided with a coupling sleeve 1. All motion
may be prevented by closing the register m.
Above and below the wheel C, the axle g carries flies n n. The fly n¹ is
composed of hinged rods provided with weights at their ends as in centrifugal
governors.
Above the chamber A is a chimney b high enough to produce a strong draught.
The air contained in the chamber A may be heated by special furnaces arranged
near to it or by the waste heat of boiler furnaces or dryers. The air is also
heated by iron or cast iron pipes Q fed with steam derived from boilers or steam
engines.
To obtain a uniform temperature as well as to assist the up draught of the air, the
shaft is provided with smaller ventilating fan wheels r.
Figure 2 shows this arrangement in plan partly in section on the line I-II of
Figure 1.
In the arrangement shown in Figure 3 the wheel C is fixed upon a horizontal
axle g and transmits motion directly to the pulley S. The hot air is led by a tube p
from furnaces placed in proximity.
In order to regulate the speed of the wheel C the axle g is connected by suitable
gearing to the shaft k' of a centrifugal governor whose sleeve acts upon a rigister l'.
This arrangement is also applicable to the machine shown in Figure 1.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. An arrangement of air motor characterized by the use of a fan wheel C put in
motion by the upward force of the current of hot air caused by the draught of the

page_text: chimney, the movement of the wheel C being regulated by fly wheels and by
automatic or other registers substantially as described and shown in the drawings.
2. Air motors substantially as described and shown in the drawings.
