To all whom it may concern: 1

Be it known that l, WiLnni ll. SELF, a citizen of the United States,; residing at Newton, in the county of Catawba and State of North Carolina, have invented a new and useful Device for Ventilating Hotels and Oiiice-Buildings, of which the following is a specification. I

The device forrnin the subject matter of this application is adapted to be employed for ventilating hotels, oilice buildings and other structures, and the invention aims to provide a simple but efiicient means whereby proper ventilation may be secured in super posed rooms'or compartments of a building.

It is within the rovince of the disclosure to iinprov'e generally and to enhance'the utility of devices of that type to which the present invention .appertains.

With the above and other objects in view which will appear as the description proceeds, the invention. resides in the combina tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood.

that changes in the precise embodiment of the invention herein disclosed can be made within the Scope of what is claimed \vithoul departing from the spirit of the invention.

In the accompanying dra wings Figure 1 shows in vertical section, a portion of a building,wherein the devi e form ing the subject matter, of this application has been mounted, parts appearing in elevation; and

Fig. 2 is a cross section taken approxi mately on the line 2--2 of Fig. 1.

The numeral 1 marks a building including a roof 2, a side wall 3 and any desired number of floors 4. Axially alined vertical pi pe sections 5 and 6 are provided, there being any desired number oi the sections 5, dc

pending upon the number of floors in the.

building. The pipesections 5 and (3 have flared upper ends 7 mounted in the floors 4-, each pipe section 5 having a reduced nozzle 8, spaced as shown at 9, peripherally, from the flared end 7 of the next lower section, the nozzles 8 extending downwardly into the flared ends 7. The lower pipe section 6 terminutes in an outlet 10, which, ii desired, may be carried through the, side wall 8. At 11 there is shown a blast conduit which may be extended upwardly through the root 2, the blast conduit c aninunieating will.

"it-i blower 12 on the roof, and having a nozzle 14 entering the flared end 7 of the adjacent pipe section 5. The blast conduit 11 and the pipe sections 5 and 6 are provided with lateral outlets 15, spaced from the respective floors 4:,

In practical operation, when the tan or blower l2 is in operation, a current of air will be forced downwardly through the blast conduit 11, pure air passing out through the outlet 15 of the blast conduit into the room above the uppermost door. The air adjacent the uppermost floor will be drawn into the upper end 7 of the pipe section 5 by the draft produced when air enters the pipe section 5 through the nozzle 14. In a similar way, all of the rooms below the uppermost Patented May as, ar

room Wlll be ventilated, the air ultimately being discharged by way of the outlet 10.

It is to be noted that some of the air drawn out of the uppermost room may be discharged through the outlet 15 of the pipe section 5 into the next lower room, but this fact is of no great importance, since, when the structure is in operation, the air in all ofthe rooms will be kept so, pure, compared with the air in the rooms under ordinary conditions, that no serious or annoying re suits will be produced.

lrl a vin g thus described the invention, what is claimed is:

in a ventilating system, a building comprising floors; a plurality of pipe sections each having its upper end mounted in one floor and having its lower end inserted into the upper end an adjoining section and spaced peripherally therefrom to define an air inlet; a blast conduit having its lower end inserted into the upper end of the up perinost pipe section. and spaced peripherally theretrmn to deiine an air inlet; means as scinblcd with the conduit for creating a blast through he conduit and through the pipe sections, the conduit and pipe sections havin air outlets spaced above the respecti i'c floors.

In testimony that I claim the foregoing as my own, l, have hereto affixed my signature in the presence of two witnesses.
