VENTILATING-UNIT Herbert D.'Euwer, Kirkwood, Mo., assignor to American Car and Foundry Company, New York, N. Y., acorporation of New Jersey I l Application December 30, 1947, Serial No. 794,681
Recently with the use'of certain air condition-' ing units; the entire c'ar interior has beenpla'ced under pressure and "thisip'ressure' assisted the ventilation through the eduction type fixture. Such 'fixtureshave not given ade'finite and'predictableventilation of'the cars. Itis an object, ther'eforaof the present invention to provide a forced ventilation for a railway'c'ar which does not rely on either internal or external car pressuresfor its operation. 1
'Aifjfurther objector the invention'is, the provisionfof a ventilating unit which can'be readily installed and serviced.
A still further object of the invention is the provision of a ventilating unit having a discharge grille closely conforming "to the contour of the car roof. e V I A yet further object of; the invention is the provision of a ventilating unithaving a fan swingable between a vertical in-u'se position and a horizontal inspectionor repair-position.
These and other objects of the invention will be apparent to persons skilled in the art from a study of'the following description and accompanying drawings in which 7 Figs. 1 and 1A. when taken together, disclose a complete sectional View of the unit taken substantially on line l l of Fig. 2;
Fig 2 is a sectional view takensubstantially. on 1ine2;2 'o fFig. l; :7
Fi 3 isan elevational view .of the discharge grille with parts removed to better-disclose the construction;
Fig t is a sectional viewtaken substantially on line i 6 of Fig. l;
Fig. 5 is .a sectional view taken substantially on line 5-5 of Fig. 1A, and
Fig. 6 is an enlarged-sectional view taken substantially on line 6-6 of Fi 1A.
Referring now to the drawings in detail it will be seen that the unit has been disclosed as applied to a passenger car having a curved roof 2 attached to carline 4 and purlines 6, the carlines and roof being attached to the side plate 8.
The roof sheet 2 intermediate the carlines has an opening l0 cut therein and on the inner sur- 3 Claims. (Cl. 98-49) box-like duct l2. -The outer open end of this box-like duct is flanged and rigidly attached to the roof sheet,-thereby reenforcing and stiffening the roof sheet at the opening and sealing the roof and box-like duct against passage of mois-- Inwardly of the open end of the duct is fastened a pan-shaped plate ture of the car interior.
14 having an opening cut therein for reception of an eliminator frame is which is bolted or otherwise secured to plate M and which, together with the eliminator plates carried in the,
frame, can be removed through the open outer end of the ducts. The duct member has its inner end preferably supported from either plate 22 can be attached thereto. Plate 22 forms the outer open end of a fan housing 24, having the other open end directed'downwardly toward the car interior. Rigidly attached to plate 22 shown has'integrally attached or pressed therein a flange 3ldefining a circular opening for reception of fan blades 32, these fan blades bein driven by a motor M attached to the plate 28. The plate 23 with th attached motor and fan is normally held in the vertical or operative position by a pair of releasable fasteners 34 which are adapted to grip plate 22.
r The lower or downwardly directed open end of fan housing 24 is flanged inwardly to have. at-' tached thereto the inturned flanges of a filter housing member 36. The lower outturned flanges 33 of this filter housing member are adapted to support the ceiling sheets 40 and form a binding around the opening in the ceiling plate. The filter housing is adapted to receive a filter member iz anda screen or inlet grille 44 hinged as at 46 to the filter housing and held in normal position by releasable fastening 48.
In order to permit discharge of air through the box-like duct and roof while preventing entrance j of large particles of foreign matter, a discharge grille is provided as best shown in Figs. 1A and 3.
This discharge grille is preferably formed as a" unitary structure with a substantially rectangular frame 58 conforming to the roofs curvature the carlines or purlines by means of hangers l8 and the] inner edge of the duct is flanged as at 20 so that v 3 inclined toward each other both longitudinally and. transversely of the car. The upper or base ends of the sides merge into a top member 54 directed inwardly and upwardly to merge with the upper portion of the rectangular frame. The outer edges of triangular sides 52 and top 54 terminate in a plane substantially tangent with the roof at the lower edge of the opening. In other words, their outer surface lies substantially in the plane of the lower element 56 of the rectangular frame. The sides 52 are joined by horizontal bars 58 and the top 54 and bottom '56 are joined by a vertical bar 60, which also is made integral with bars 58.
As clearly shown, the 7 upper edge of the grille is connected to the can roof by hinge 62 preferably of the continuous type and capable of excludingpracticallyall moisture coming in contact therewith. Any moisture that may enter the duct through the open grille Work or along the sides of the grille can discharge out of the duct due to the slightsp'acing of the lower edge 56 from the roof as shown in Fig. 1A. The "grille as shown in Fig; 6 is held in position'agains t swinging by means of "screw:
fasteners' fi l fastened through the lower edge of the grille and into plates 66 fastened on the interior of duct I2.
The grille' w'ill, due to itscl oseconformation; to the car roof, enhance the appearance of the car While at the same time permitt ing effi cint discharge of air from the car interior.
of air around 'the"'grille soas not to hamper discharge ofi'air through the grille. The eliminators in eliminator housing 16 will prevent entrance of moisture any distance into the duct under conditions when forced ventilation is not in use.
or'iless' in detail, with. specific reference to A the drawings, it will be'obvious' to persons skilled inthe' art that various modifications and rearrangem'ent's of parts maybe made and all such modifications and rearrangementsare contem pla'tedjas will fall within thescope of the appended claims;
What is claimed is:
1. An'exha'ust ventilator fora railway passenger carlhaving a curved'roof with an opening cut therein for the passage of air 'throu gh the roof, a member overlapping the opening and comprising an open,substantiallyrctangularbase frame conforming to the roofcurvature, sides of gen erally triangular formexte'nding outwarclly of the carfrom the base frame em imec ta ward each otherbothlongitudinally and transversly of'th'e car; and a top connecting sa idisi des andbas'e" frame and extending outwardly and downwardlyfro'm'the 'upp'er'edge 'of the base The inclined sides 52 will assist in directingthe flow frame, said top and sides terminating in a plane" substantiallytangent to the roof and lower edge of said base frame and defining an exhaust opening for the passage of air.
2. An exhaust ventilator for a railway passenger car having a ucrved roof with an opening cut therein for the passage of air through the roof, a member overlapping the opening and comprising an open, substantially rectangular base frame conforming to the roof curvature, sides of generally triangular form extending outwardly of the car from the base frame and inclined toward each other both longitudinally andtralri'sverselyofthe car, a top connecting said sidesjand'base frame and extending out- Wardly and downwardly from the upper edge of the base name; said 'top and sides terminating in a plane-=substantially tangent to the roof and lower edge of said base frame, and horizontal and vertical bars connecting said sides and top and definingtherewith openings for the passage of air.
