Improvements in Apparatus for Ventilating Railway Carriages
and other Vehicles.
I WILLIAM YOUNG OBER of Lynn in the County of Essex and State of
Massachusetts one of the United States of America, Inventor do hereby declare
the nature of my invention for IMPROVEMENTS IN APPARATUS FOR VENTILATING
RAILWAY CARRIAGES AND OTHER VEHICLES to be as follows:-
My invention consists in a car ventilating system comprising a water tank
through which the air is forced by a fan rotated from the car axle. in one direction
irrespective of the direction of movement of the car branch pipes leading from the
fan casing into the car between the windows, and registers into which said branch
pipes open, provided with independently movable doors to control the outlet of air
into the car.
The car body is provided with the usual windows, separated by upright portions,
and the trucks may be all as usual.
At the bottom of the car, near its centre is placed a water case or jacket and
above is a rotating fan. The case is provided with holes to supply the fan with
air, and at each side, the case or jacket has hollow arms, which lead the air from
the case into air chambers, one at each side of the car, and extended from end to
end thereof below the car body.
These air chambers have vertical branches extended upward between the outer
shell of the car body and its lining, between each window at each side the car, the
said branches terminating in registers having preferably two wings or doors
pivoted at bottom and top, so that either wing may be kept open as desired, the
wing at that side of the register in the direction of movement of the car being left
to stand or project at right angles to the side of the car, that being the preferable
door to keep open as it prevents the current of air striking the back of the head
of the person in the seat next ahead of the register.
The fan having its blades inclined from a vertical line so as to force the air
drawn into the case, through the openings down upon the surface of the water in
the case, to free the air from dust and cinders before entering the car, has its
axle or shaft supported in suitable bearings, the said shaft having upon it a
bevel gear.
The truck axle has fast on it a bevel gear which engages a bevel gear on and
rotates a shaft sunported in a hearing.

page_text: This shaft is connected by a knuckle or swivel joint coupling with another shaft,
in turn connected by a like knuckle or swivel joint one part of which is connected
with another shaft.
The latter shaft has mounted upon it loosely at the opposite sides of the bevel
gear and between two collars fast on this said shaft, two clutch gears, the latter
of which rotates the fan when the car body is being run in one direction, the
latter gear being the driver when the car body is being run in the opposite
direction.
The interior of the hub of each clutch gear is provided with three inclined
pockets with friction rolls or cylinders that when the shaft is rotated one way
cause the rolls or cylinders to lock the gear to and so as to be moved by the said
shaft, the rotation of the said shaft in the opposite direction causing the rolls or
cylinders to be moved into the large ends of the pockets leaving the gear free
or loose.
The pockets of the two gears are so cut that when one gear is locked to the shaft
the other will be loose.
As the car is travelling about a curve, provision is made for the shafting,
actuating the fan from the axle, to lengthen and then shorten to a straighter
track.
To do this the shaft between the knuckles or swivels is divided, one part having
attached to it a slotted sleeve, while the other part or piece of the said shaft has
à pin or pins to enter the slot of the sleeve.
Both doors or wings may be closed, being free to be lapped or closed, the one
over the other.
By the apparatus described the interior of the car may be supplied with fresh air
free from dust and cinders.
{
Cinders accumulating in the case or jacket may be removed by taking off the
cap or cover screw which will be packed to form a water tight joint, the cover
being screwed on a threaded projection of the case or jacket.

I WILLIAM YOUNG OBER of Lynn in the County of Essex and State of
Massachusetts one of the United States of America, Inventor do hereby declare
the nature of my invention for IMPROVEMENTS IN APPARATUS FOR VENTILATING
RAILWAY CARRIAGES AND OTHER VEHICLES, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
My invention consists in a car ventilating system comprising a water tank
through which the air is forced by a fan rotated from the car axle in one direction
irrespective of the direction of movement of the car branch pipes leading from the
fan casing into the car between the windows, and registers into which said branch
pipes open, provided with independently movable doors to control the outlet of
air into the car, all as I will now proceed to particularly set forth and claim.
Figure 1 in elevation, shows a car provided with my improvements, the car
body being broken out centrally to shorten the figure, and at its sides to represent
part of the car between its outside sheathing and lining and also the interior of
the car, the case or jacket being also broken out.
Figure 2 is a partial section in the line X-X Figure 1 looking down.
Figure 3 is a partial transverse section of Figures 1 and 2 in the dotted line
Figure 4 is an enlarged inner side view of part of the car, and one of the
registers, both doors being open.
Figure 5 a vertical section of Figure 4.
Figure 6 a cross section of Figure 4.
Figure 7 an enlarged detail of one of the clutching gears, and
Figure 8 an enlarged detail of the coupling sleeve and shaft connected by it,
the sleeve being omitted from Figures 1. and 2.
The car body A provided with the usual windows B, separated by the upright
portions C, and the trucks D. D. are and may be all as usual.
At the bottom of the car, near its centre I have placed a case or jacket E to
contain water, and above the water a rotating fan F. The case is provided with
holes a to supply the fan with air, and at each side, the case or jacket has hollow
arms E¹, which lead the air from the case into air chambers E², one at each side of
the car, and extended from end to end thereof below the car body.
These air chambers E2 have vertical branches e which are extended upward
between the outer shell of the car body and its lining, between each window at
each side the car, as shown by full and dotted lines, the said branches terminating
in registers R having preferably two wings or doors e¹, e pivotted at bottom and
top, so that either wing may be kept open as desired, the wing at that side of the
register in the direction of movement of the car being left to stand or project at
right angles to the side of the car, as shown by the dotted line Figure 6, 'that
being the preferable door to keep open as it prevents the current of air striking
the back of the head of the person in the seat next ahead of the register.
The fan F having its blades inclined from a vertical line so as to force the air
drawn into the case, through the openings a down upon the surface of the water
in the case, to free the air from dust and cinders before entering the car, has its

page_text: axle or shaft 2 supported in suitable bearings, the said shaft having upon it a
bevel gear 3.
The truck axle G has fast on it a bevel gear g which engages a bevel gear glon
and rotates a shaft g2 supported in a bearing g³.
The shaft g is connected by a knuckle or swivel joint coupling h with a shaft h¹,
in turn connected by a like knuckle or swivel joint h³ one part of which is
connected with a shaft h³.
The shaft 3 has mounted upon it loosely at the opposite sides of the bevel
gear 3 and between two collars 4 and 5 fast on this said shaft, two clutch gears 6
and 7, the latter of which rotates the fan when the car body is being run in the
direction of the arrow 10, the latter gear 6, being the driver when the car body is
being run in the opposite direction.
The interior of the hub of each clutch gear 6 and 7 is as herein shewn, provided
with three inclined pockets 8 see Figure 7 in which are placed friction rolls or
cylinders 9 that when the shaft 3 is rotated in the direction of the arrow in
Figure 7 cause the rolls or cylinders to lock the gear to and so as to be moved by
the said shaft, the rotation of the said shaft in the opposite direction causing the
rolls or cylinders to be moved into the large ends of the pockets 8 leaving the gear
free or loose.
The pockets of the two gears 6 and 7 are cut in such directions that when one
gear is locked to the shaft as described by the rotation of the said shaft in one
direction, the other will be loose.
As the car is travelling about a curve, provision has to be made for the
shafting, actuating the fan from the axle G, to lengthen and to again shorten as
the car arrives on a straighter track.
To do this the shaft h₁ between the knuckles or swivels h, h². is divided, one
part having attached to it a slotted sleeve 12 shown in detail Figure 8, while the
other part or piece of the said shaft has a pin or pins to enter the slot of the
sleeve.
If desired both doors or wings e¹, e² may be closed, they as herein shown being
free to be lapped or closed, the one over the other.
By the apparatus described the interior of the car may be supplied with fresh
air free from dust and cinders.
I do not desire to limit my invention to the exact location of the air chambers,
or of the fan, and instead of the particular shafting shown, to rotate the shaft h³
I may use what is known as the stow or flexible shafting. The water is shown
in w Figure 1.
Cinders accumulating in the case or jacket may be removed by taking off the
cap or cover screw m which will be packed to form a water tight joint, the cover
being screwed on a threaded projection of the case or jacket.
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
In a car ventilator, a water-tank, fan, branch pipes leading into the car between
the windows, and means, substantially as described, to rotate the fan to force the
air supply, in combination with the registers R in which the branch pipes terminate
having the independently movable doors or wings e¹, e², substantially as shown and
described.
