WILLIAM L. WALSH,

CAR-VENTILATOR.'

0F NEW YORK, N. Y..

To all Iw/iom it may concern: Be it known that I, WILLIAM L. WALSH, a citizen of the United States. and a resident of the city of New York, bo-rough of Manhattan, in the county and State of New York, have invented a new and Improved Car-Ventilator, of which the following is a full, clear, and exact description.

Among the principal objects which the present invent-ion has in View are: to provide a iiue or covered passage from which the air may be drawn by the operation of the train and regulating devices to govern the extent of the communication between the interior of the car and said passage; 'to provide auxiliary boxes or chambers having communication with the interior of the car through controlled passages, the air in said chambers being exhausted by the travel of the car; to provide means operable from disposition of t-he draft members of the ventilator; and to provide draft members for said flue and boxes extended beyond the influenceof the eddying currents formed b the movement of the car body. i

One embodiment of the present invention is disclosed in the struct-ure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts. in all the viewsyand in which- Figure 1 is a perspective view of a railway car having a ventilator constructed and arranged in accordance with the present invention; Fig. 2 is a longitudinal vert-ical section taken through the flue of said ventilator; Fig. 3 is a cross section of the top of the car showing the ventilator as applied` thereto; and Fig. 4C is a `perspective view showin a modified form 0f the invention.

As s own in the accompanying drawings, the Ventilating windows 9, 9 open into a passage or iiue formed by extending the lantern roof of the car over the main roof and filling the space between the lantern roof and mainl roof by means of solid boxing sides 10. By this arrangement a boxlike flue 11 'is formed, as shown best in Figs. 2 and 3 of the drawings. Disposed at intervals, and preferably at the ends of the flue thus formed, are small hollow towers 12. A`s\ seen best in Fig. 2 of the drawings the towers 12 are each covered by a hood 13. The hoods 13 have a solid cover and a cylindrical side wall 14. The side walls 14 are perforated to form the openings 15. 1

Specification of Letters Patent. l Patented M31-, 18, 1913 Application ated August 31,1911. f

Serial No. 647,011.

The hoods 13 are fxedly mounted-at the.

upper end of vertically disposed shafts 16. Each of the shafts thereon. a bevel gear wheel 17. The towers l2 and covering hoods therefor are arranged. in pairs, preferably disposed at the' same position relative tothe length ofthe car. The shafts 16 at each end of the car are operatively connected by a transmission shaft 18. The shaft 18 is provided with a bevel vgear wheel 19 ixedly mounted at each end of the said shaft and in'mesh with the bevel gear wheel 17 on each of the shafts 16. One of the shafts 16' is elongated and is pr,ovided at the lower end thereofwith a hand wheel 20 whereby the train attendantmay rotate the shafts therewith.' In the 'operation of the invention the hoods 13 are so disposed with reference to the travel of the car that the openings 15 are turned from the direction of travel, thus forming a suction to draw from the flues 11 the air contained therein. Rarecation of the air wit-hin the flues 11 is prevented by `the flow of the air from the body ofthe carV into the said iues to through the towers therefor.

be removed `therefrom 12 and the hoods 13 The quantity of air passing from the body of the car to the ues 11 is regulated by the adjustment of the sashes'21 to vary the opening of the windows. 9.

16 has rigidly mounted 'Y .I

16 and hoods 13 connected As seen by reference to Fig. 2 of the draivings, the operation of the towers 12 at each .end of the flues 11 ldraws the air from the said fiues in both directions and towardboth ends thereof. In this manner a constant drain on `the dead or foul air of the car is exerted by the flues 11 and the towers 12 operating therein. v

In Fig. 4 of the drawings a modified form of the invention is shown,`wherein the towers 12 and hoods .13 are mounted uponboxes 22. The boxes 22 are constructed of any suitable material, that preferred by me being sheet metal. The boxes are open toward the wind ows 9. The length of the said boxes 22 is' preferably such as to cover two or more of the windows 9. As sh/ownin the drawings, it is preferred that'each of the boxes hould have a tower 12 centrally located t.

the towerabove the car roof more than a predetermined distance for fear of striking structures extended across the road bed, or

on. In constructing the towers 12 and hoods therefor care 1s exercised not to raise the opening in tunnels through which trains have to pass. Due cure is also eXercised to remove the opening 15 of thv cover for any of the counter-currents or eddies formed by lthe cal' structure on the air through which the saine is moving.

Having thus described my invention, what I claim asnew and desire to secure by Letters Patent is In a car ventilator having a verticallyr4 disposed tower, the sides of which are open in opposite directions; a hood having a. closed top, and a circular side wall pendent therefrom, said side Wall being provided 15 with an opening to register With the openings in said tower; a shaft fixedly connected with, to support, said hood, said sha-ft being disposed concentric with said tower and hood; a hund wheel mounted :1t un operat ing station; and transmission mechanism operatively connecting said hand wheel and said shaft.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
