To oZZ whom 'it may concern:
Be it known that l, JAMES M. SiiriiioUR, a

EachV lock is provided witha pail of suitably constructed and operated lock doors or gates 8 kat theirireceiving for-*entrance ends, andiwith a pair of 'similari lock 1 do'ors or-l gates .-9 atntheirzdiscliarge orexit'ends. ff It. isi 1,10
In. the f desirable, in practice, that each lock be long enough to accommodate at one time from six to eight motor vehicles, although, of course, it will be clearly understood that the same may be modified in such particular to suit the requirements of the particular' tunnel location.
Suitably located and housed above the tunnel entrance and its locks are a plurality of fresh air impelling mechanisms of any desired type, such, iter example, as the rotary` fans l0 shown in the drawings; These air impelling mechanisms are connected through suitablyy disposed air delivery conduits or passages lll with the entrance portal or end d of the :tunnel at a point somewhat beyond the inner or discharge ends of the locks 5, 6 and?. Suitable shut-ofi' valves or` gates 12 with the required operating mechanism may be providedin connection with each air delivery conduit, or passage, whereby the volume of air delivered may be either variously controlled or entirely cutfott if desired.
Thev method of Ventilating a vehicular tunnel, particularly designed to lac commo-` date motor vehicular traliic, and which may put in elieetby the above describedstr'ucture, consists in delivering into the entrance.
end 'of 'the' tunneland impelling therethrough to the exit endv thereof,or other suitable venting points, a large volume of air at comparatively low pressure, said air being caused to travel through the tunnel passage or .way with or-in the ldirection `oi? traffic movement, and at velocity in excess of or greater than the permitted speed of vehicles moving therethrough, thus utilizing practically the entire area of the tunnel as a fresh air conduit. To assure proper and continuous directional flow of the air stream thus permitted, checks against backward esj cape of air from or through the vehicular entrances to the tunnel are provided, of such a nature that comparatively rapid 'access to the tunnel interior by vehicles may be attained without in any way interrupting or disturbing the directional flow of the air,
or diminishing the desired volume of the air stream. By virtue of such method, a comparatively large volume of air at low pressure may be moved at desired velocity through the tunnel interior, with a relativelysmall expense for power. Since the air is impelled through the tunnel, in the` direction of traiiic and in company with the vehicles moving through the tunnel, said vehicles will `not impede the flow of air, but will really aid in maintaining said flow, andwill tend to prevent lagging of the air stream. f
In cases where a single lock is employed the inner lock gates 9 at the discharge end ot the lock are'closed against backwardY and outwardlow of air tending to check and interfere withthe continuous vflow of air through the tunnel, and the outer loclr gates 8 are opened, so that vehicles may be driven into the lock. When the lock is illed with vehicles, or it is otherwise deemed advisable to permit the passage of vehicles from the lock into the tunnel, the outer lock gates 8 are closed, and the inner lock gates 9 are` opened, so that the lock is thrown into communication with the tunnel way 2, and the vehicles are free to enter. The lock being Opened to communication with the tunnel,` the outer lock doors 8 serve to prevent backward escape of the Ventilating air under such conditions. y y
In cases where two or more locks are employed, as shown in the drawings, the locks are manipulated successively to open and close thesame to the entrance and exit of vehicles, so that while the group of cars i arrangement of the parts and devices employed, `without departing from the general` scope and principles of the said invention, hence, I do not limit myselfto the exact arrangement and relations or construction of parts as above described, or as illustrated in the accompanying drawings. 'Y
I claim f l. A method of ventilating vehicular tunnels, comprising the impulsion of a large volume of air through the tunnel way from the entrance to the exit thereof, and locking said' air against backward escapefrom the tunnel 'entrance while-vehicles are being ad mitted for entrance into said tunnel.
2. A method of ventilating vehicular tunnels, comprising the delivery of a large volume oit' air into lthe tunnel entrance,im peiling said air through the `tunnel way in the direction of trahie movement for discharge at or near the exit end of the tunnel, and locking said air against backwardescape from the tunnel entrance while vehicles arebeing admitted for entrance into said tunnel.
3. A method of ventilating vehicular tunnels, comprising the delivery vof aA large volume of air at low pressure into the tunnel entrance, impelling said air through the tunnel way in the direction oftraiiic movement and at a velocity in excess of the permitted air at or near the tunnel eXit, and locking said air against backwardescape Vfrom the' ,4
tunnel entrance while vehicles are being admitted for entrance into .said-tunnel;
4;. The combination with a vehicular tunnel of means for delivering to and continuously moving air through said tunnel from its entrance to its exit end, and an air lock at the tunnel entrance providing means for admitting vehicles to said tunnel while preventing backward and outward escape of air from said tunnel entrance.
5. T he combination with a vehicular tunnel of air moving machinery, a conduit for delivering air from said air moving machinery into the entrance of Said tunnel for continuous movement through the tunnel way from its entrance `to its exit end, and an air lock rearward 'of the discharge end of said' delivery conduit and adapted to communicate with said tunnel entrance providing means for admitting vehicles to said tunnel while preventing backward and outward escape of air from said tunnell entrance.
6. The combination with a vehicular tunnel of air moving machinery, a conduit for delivering air from said air moving machinery into the entrance of said tunnel `for continuous movement therethrough toward the eXit end of the Same, and an air lock at said tunnel entrance having inner and outer lock doors.
In testimony that I claim the invention set forth above I have hereunto set my hand this 15th day of January, 1921.
