THE COLUMBIA PLANOGRAPH co WASHINGTON, D- c WILLIAM JAMES SMITH, 0F PORTAG-E LA PRAIRIE, MANITOBA, CANADA.
VENTILATOR.
To all whom it may concern:
Be it known that I, WILLIAM JAMES SMITH, of the city of Portage La Prairie, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Ventilators, of which the following is the specification.
The invention relates to improvements in ventilators particularly designed for use in farm buildings such as stables for carrying off the accumulating foul air and the object of the invention is to provide an easily installed, inexpensive, simple, durable and effective device for withdrawing by means of a forced draft, the foul air from the building.
With the above object in view the invention consists essentially in an interior fresh air flue leading from a suitable location at the lower part of the building to a suitable position at the top of the building, a foul air pipe opening to the air flue and positioned approximately immediately below the first floor of the building and a valve associated with the pipe, the parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which Figure 1 represents a side view of a building equipped with my invention.
ig. 2 represents a cross sectional view through the building showing the device installed.
Fig. 3 represents an enlarged detailed sectional view through the appliance as detached from the building.
Fig. 4 represents a horizontal sectional view through the appliance, the section being taken in the plane denoted "by the line XX Fig. 3 and looking downwardly.
Fig. 5 represents a face view of a fragmentary portion of the air flue and showing the foul air pipe and valve.
In the drawing like characters of reference indicate corresponding parts in the several figures.
Here I wish to state that although I have shown the invention as applied in a barn or stable, still I wish it to be understood that it can be utilized on any building for ventilating purposes and further, while I have only shown it as utilized for ventilating what might be called the lower story, I wish it to be understood that if necessary the Specification of Letters Patent.
Patented July 1, 1919.
Application filed September 2a, 1918. Seria1No.255,8 26.
various stories of abuilding could be ventilated by usingseveralof the appliances, one for each story. a 1
Reverting now to the drawing, 1 represents a barn or stable of ordinary construction presenting the side walls 2 and 3, end walls 4 and 5 and roof 6 which inclose the ground floor 7 and firstfloor 8.
customarily in barns of this type live stock is housed within the lower story and the upper story is utilized for storing food for the animals. It is found that where no system of ventilation is provided the air becomes very foul which is injurious to the health of the animals.
In order to effectively draw oil the foul air which naturally rises, I have'provided in the present instance two similar fresh air flues 9 and 10 located more or less centrally at opposite sides of and within the barn and passing upwardly beneath the roof to the peak of the roof where they open to a common vent pipe 11 capped by a suitable cowl 12.
The lowermost ends of the fines are projected through the side Walls of the barn as indicated at 13 and 14 so that a draft of air is effected in an upward direction through these fines to the vent pipe.
Preferably the lower ends of the flues open to the sides of the barn in a location such that they will not be covered over by snow or otherwise interfered with.
In a location adjacent the first floor 8 I locate a foul air pipe 15 opening to each flue and positioned so that it will draw off the foul air from the lower story of the barn wherein the animals are housed.
Here it will be noticed that the foul air pipes embody a member 16 actually in the nature of a baffle plate which extends at an angle across each air flue. The lower ends of the foul air pipes are each fitted with a sliding Valve 17 whereby the entrance opening to the foul air pipe can be controlled.
With this device installed it will be seen that when the valves 17 are closed there is no ventilation eflected as there will at this time only be an up-draft of fresh air through the flues. However, upon one opening the valves the foul air has a natural tendency to rise and is sucked up, so to speak, by the fresh air in theflues and is carried off with the fresh air through the vent pipe 11 as will be readily understood. By
opening or closing the valve the greater or less the capacity of the appliance.
What I claim as my invention is A ventilator for a two-story barn OOHlprising an lip-going interior fresh air flue following the Wall and roof of the learn and opening at thebottoln through-the Wall to the exterior air and at the top through the peak of the roof to exterior air, an upwardly ineliningioul air pipe leadin from the ceilingof the first story of the am to the interior of the flue and having one side thereof forming a baffle plate extending upwardly at an angle partially across the flue and an adjustable valve controlling the entrance end of the foul air pipe.
Signed at Portage La Prairie, this 10th day of September, 1918.
