WILLIA HEYWOOD MOTTERSHALL, or THORNI-IILL, onramo, Mme
VENTILATION sYs'rnM.
Application file d August is, 1923. seriaino. 657,821. I
To aZZ whom it may concern:
Be it known that I, WVILLIAM HEYWooD MOTTERSHALL, a subject of the King of Great Britain, and a resident of the village of Thornhill, in the county of York, in-the Province of Ontario, Canada have invented certain new and useful Improvements in Ventilation Systems, of which the following is the specification.
My invention relates to improvements (111' ventilation systems and the object of the invention. is to devise means whereby the vitiated air inbuildings and other structures will be 'more readily removed than is the case at present.
' A. further'object is to devise means for in creasing tliev'elo'city of'the vitiated air due to its being increased in density whereby the suction into the ventilating shaft isin: creased with the consequent'increase in the velocity of the up current of air.
A still further object is to devise an improved means of ventilation equally applicable to buildings, automobiles, steamboats,
r railways and all closed vehicles.
My invention consists of a ventilation system constructed and arranged all as here inafter more particularly described and illustrated in the accompanying drawing in which:
Fig. 1 represents a vertical section through a building showing my system applied thereto.
Fig. 2 is a longitudinal section through two of the horizontal spaced apart cones used in my system, and
Fig. 3 is. a cross sectional line 4.& Figure 2.
. Like characters of reference indicate corresponding parts in the different views.
1 are the walls of the building. 2 arethe ceilings of the respective floors. tical ventilating shaft extending down through the building and up through the roof thereof, said shaft 3, if desired, being at its top with a revolving cowl of the type set forth in my United States Patent #1,528,683 issued March 3, 1925, or of any standard type.
In my construction I dispose my spaced apart cones in three distinct ways. For example, on any floor I may provide a horizontal branch shaft 5 from which depends view through the the hollow conical member 6 communicating therewith and into which is inserted the 3 is the vercylindrical shank 7 of the hollow' conical member 8, sald shank being ofless diameter I than the neck of the member 6 and consef quently being space d therefrom. Below the hollow conical member 8 I provide a funnel shaped member 9with its flared mouth di rected downwardly, the outlet 10 0f said member 9 being of less diameter than the diameter of the cylindrical shank? of the hollow conical member 8 into which it is inserted, and into the inlet end of the funnel shaped'member 9 I insert the hollow conical member 11, its outlet again being of less diameter than the' neck of the funnel shaped member 9, such hollow conical member 11 being-so disposed that its larger end is lower 11 ost..',- V y The members 6, 8, 9 .and 11 are disposed vertically and are particularly adapted to be set over machines, cooking ranges and in other positions in a-room where it is desired to remove foul air. In the drawing one set of these members 6, 8, 9 and 11 is provided at the bot-tom of the shaft'3, but-it is to be understood that they will be equally effective if dependingfrom branch shafts connected to such vertical shaft, both constructions being illustrated in Figure 1 of the drawing.
For general, ventilation" purposes in a' building I provide a series ofdouble hollow conical members 12 of funnel shape, as is clearly illustrated in Figure 1, said members being secured by hangers 13 in spaced relation to each other so that their longitudinal axes are substantially horizontal, the necks 14 of each member inserted into the air inlet end of the next hollow conical member.
In constructing the conical members 12 I preferably provide an adjustable central portion as illustrated in Figure 3 wherein the cylindrical end 15 of the neck portionv is adapted. to telescope into a cylindrical portion 16 in the skirt portion, thus permitting ofthe necessary adjustment in length of these two portions of each member, the neckportion of each member being provided with radially extending webs 17 with turned over feet 18 adapted to engage the interior of the skirt of the next conical member.
When the system is installed, a portion of is increased in, density with the consequent increase in velocity and thus as itisexpelled into the second conical member 9 a suction is created on the air that isbeing the vitiated air entering the lower cone 11 v the smaller end of such member 9.
current of air is increased prior to introduction into the transverse shaft 5 and the vertical shaft 3. a In the case ofthe horizontally disposed conical member .12 the vitiated air in the room passes into each member 12 and as it passes therethrough, it-increases in density With the consequent increase in velocity, thus creating an'increased suction on the air introduced into the next member 12.
Owing to the adjustability of the neck and skirt portions of the members l2 it Will be seen that the amount of introduced into a member can be controlled as desired, depending upon the particular conditions in the room.
From the above description it Will be seen that'I have devised a simple and effectiveventilating system which can be readily installed and which Will materially increase the I elficiency of ventilating or chimney shafts.
It is to be understood that the horizontally disposed cones and thevertically disposed cones in the room, can be used in conjunction with each other, or may be used separately if desired, depending upon the ventilation necessary in the building.
' What I claim as myinvention is 1. In ventilation systems, a plurality of spaced apart funnel shaped members, each comprising a neck portion and a coacting skirt portion, such portions longitudinally adjustable With respect to each other, each neck portion inserted into the skirt portion of the next member, such neck being of substantially less diameter than the diameter of such skirt portion, and means for holding the necks in their centred posi tion in the skirt portions.
2. In ventilation systems, a plurality of spaced apart funnel shaped members, each comprisinga neck portion and a coacting skirt portion, such portions longitudinally adjustable With respect to each other, each neck portion inserted into the skirt portion of the next member, such neck being of sub stantially less diameter than the diameter of such skirt portion, and. a plurality of outwardly extending Webs secured to each neck and adapted to engage the interior of each skirt portion.
