Application filed July 10, 1925.
This'invention relates to improvements in ventilators and has for its object to provide a ventilator efficient in operation and particularly adapted for use with refrigerator or other cars and capable of being arranged for proper functioning in either direction of travel when applied to a car. Another object is to provide a ventilator of this character in which the entrance of back drafts, cinders, water or the like will be prevented. Still another object consists in the provision of a ventilator of this character which may be readily attached to cars of difierent construction.
These and other objects will be more fully set forth and described in the following specification and shown in the accompanying drawings in which v Fig. 1 is a plan view of car with a pair of my ventilators attached;
Fig. 2 is an end elevation of one of my ventilators showing its attachment to one type of car roof;
Fig. 3 is a vertical section along the line 33 of Fig. 1;
Fig. 4 is a plan view of my ventilator.
Fig. 5 is a plan view with the cap removed;
Fig. 6 is a horizontal section through my ventilator;
Fig. 7 is a view similar to Fig. 2 showing attachment of my ventilator to another type of car roof.
Like numerals refer to like elements throughout the drawings in which A designates generally a refrigerator car with a pair of my ventilators generally indicated by numeral 10 attached thereto at the roof thereof. The ventilator is in the nature of a head having a depending neck 10 centrally apertured and threaded for engagement by a threaded pipe 11. Surrounding the neck 10 is the collar 1O inclined to accord with the inclination or slant of a car roof Located above the neck 10 and and in connection therewith is the lower chamber 1O from which leads the passage 10 in the chambered partition 10% which also communicates with the upper chamber 1O formed by the ceiling or top wall 10 and the cap 10*, which is removably secured by screws 12 13 or the like to the top wall 10 (see Figs. 3 and 4 for example). Extending through the ventilator head are the eduetioii passages if) separated by the chem:
Serial No. 42,726.
wall or ceiling 1O are provided the elongated ports 10 (see Fig. 5 for example) affording communication between the chamber 10 and the eduction passages 10,- and formed by cross strips or in any suitable manner. i I
In attachment to the carroof shown in Figs. 1 to 3 for example, the roof face is suitably apertured to permit the insertion of the neck 10*" of the ventilator head, a packing ring or gasket 14 being located beneath the collar 10 as shown in Fig. 8. The carline A is also apertured to accommodate the neck 10 and the pipe section 11 and the threaded collar 15 and lock nut 16 being threaded on the pipe 11 to clamp the ventilator in position. In Fig. 7 I have shown the method of attachment of the ventilator to another type of car roof in which dead air or ceiling space A is provided above the false roof A The mounting is substantially similar to that shown in Fig. 3, for example, save that the pipe 11 is of sutlicient length to meet the requirement of the dead air space.
The ventilator is preferably mounted with its axis of movement parallel tothat of the major axis of the car so that one entrance 10 faces the front end of the car and the other faces the rear end of the car, the exits 10 being parallel to the sides of the car. In this arrangement when the car is traveling in either direction an eduction current of air will flow through one of the passages 10 creating an eduction effect therein and drawing; the air from the interior of the car or other chamber to be ventilated through pipe 11, chamber 10. chamber baffle 10 upper chamber 10, and ports 10. At the same time some suction will obtain in the other eduction passage 10 due to flow of the air past or throiwh it, assisting the exhaust of air through t e ventilator- The location of the ducts and ports is such as to prevent at back drafts carrying finders,-
of the chamber to be ventilated, regardless of the direction of the surrounding air currents. .7 I
It will alsobe apparent that my ventilator is readily adapted for attachment to any type of car. The cap 10 being readily described except as defined in the appended claims 4 What I claim is: v 1 A ventilator comprising a body having a longitudinal passage. th'erethro'u'gh, said pass'a e being provided with an entrance and 'n exit, the exit beingarranged at a plane angu'larly disposed with respect to the plane ofthe entrance; the said body being further provided with a duct at right angles to 'thei axislot said passage and a chamber located above said passage and in communi cation therewith, said duct also communicating with said chamber. a
2; A ventilator-comprising a body portion having pair of longitudinally arranged passages; theyentraiices thereto being opposed, each of said passages being further previded with an exist, the planes "of such sages and communicating with said chamber,
said chamber being in communication with said passages. I
3. A ventilator comprising a body and a pair of longitudinally arranged passages therethrough, a partition separating said passages, said partition being hollow to form a duct and means to provide communication between said duct and said passages, each of said passages being provided With an entrance and an. exit, the exit being in a plane substantially at right angles to the plane of the entrance, p
4. A ventilator comprising a body and a pair of longitudinally arranged passages tlier'ethrougln: a partition separating said passages; said partition being hollow to form V a duct andn'ieans to provide communication between said duct and said passages, each of said passages being provided with an entrance and an exit, the, exit being in a plane substantially at right anglesto the plane of the entrance, one entrance being offset with respect to the other. v p .7
In witness whereof, I hereunto subscribe my name to this specification. V
