Specification of Letters Patent.
Patented Oct. 29, 1918.
Application filed August 29, 1913. Serial No. 787,378.
To all whom it may concern:
Be it known that we, THOMAS E. VAUGHN and JOHN H. BRUNINGA, citizens of the United States, and residents of St. Louis,
Missouri, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.
This invention relates to ventilators for buildings, chimneys, and the like, and more particularly to ventilators of the ejector type.
One of the objects of this invention is to provide a ventilator which. not only forms an outlet opening for the air from abuilding or the like, but which is so constructed that outside air currents striking the same will produce by an induced action a. strong exhaust of the air building.
Another object is to provide a ventilator which will be simple in construction, cheap to manufacture, will require a minimum of invention,

Fig. 3 is an enlarged detail section on the line 33 Fig. 1, with the damper sleeve in raised position,
Fig. 4 is a vertical section on the line 1 Fig. 5, showing another embodiment of this invention,

Fig. 7 is a section on the line 7-7 Fig. 6,
Fig. 8 is a vertical section on the line 88 Fig. 9, showing another embodiment of this invention, and
Fig. 9 is a section on the line 9-9 Fig. 8.
The ventilator is preferably constructed of sheet metal. Referring to the accompanying drawing, and more particularly to Figs. 1, 2 and 3, 10 designates an eduction pipe and 11 an outside casing of frusto-conical form. The casing 11 is spaced from the eduction pipe 10 by means of a series of a series of vertical from the interior of the lobes, each comprising a body portion 12 extending transversely or circumfereniiially along the pipe 10 and having wings 13 bent up at its edges and provided with flanges 141. The lobes are riveted to the eduction pipe and to the casing 11 as shown in the drawing so as to hold the casing in spaced relation with respect to the pipe and to form passages extending along the pipe. The wings 13 preferably extend below the lower edge of the casing 11 and preferably taper to .the eduction pipe as shown in Fig. 1.
, A cap 15 having an inverted cone 16 and a rim 17 is supported on and in spaced relation with respect to the casing 11 by means of a series of straps or standards 18 riveted to the cap and the casing.
A damper comprising a sleeve 19 is mounted to slide in or on the eduction pipe 10. This sleeve is provided with a cross bar-20 secured at its ends, as by soldering or riveting, in the sleeve, so as to provide convenient means where y the damper may be raised and lowered. The damper sleeve has secured thereto a pair of spring latches 21. The latch is constructed of spring wire or the like and is secured at 22 to the damper sleeve while the other end is free. The free end is bentout-wardly as shown at 23, extends through an opening 2% and lies in a depression25 of the sleeve. The end is bent over as shown at 26 so as to work in an aper ture 27 in the sleeve. The end 23 is bent to form a cam shaped portion 28.
When the damper sleeve is moved upwardly todotted line position as shown in Fig. 1, the upper end of this sleeve will bear against the inverted cone 16 and effectively close the ventilator. In the raised position of this damper as shown in Figs. 1 and 3 the end 23 of the latch will take over the upper end of the eduction pipe to latch the damper in raised position. The damper can be readily lowered by simply pulling down on it, since the cam portion 28 will engage the upper end of the eduction pipe and move the latch inwardly into the depression 25/ It will be noted that when the damper sleeve is in open position the ventilator will be entirely unimpeded so that no obstructions whatsoever are formed to the free rising air currents. When however the damper is closed the draft will be entirely cut oil and l the ventilator will be entirely sealed. This renders it especially adaptable for railway cars which have to pass through tunnels Referring now to Figs. 4L and the educ tion pipe 10 and the casing 11 are held in spaced relation by wings 30 comprising Z shaped plates secured by rivets passing through the flanges of the wings and through the eduction pipe and casing respectively. The standards 18 are secured to the casing by the same rivets which secure the wings 30 in position. The wings 30 in this case also preferably extend below the lower ec ge of the casing 11 and also preferably taper to the eduction pipe 10, but it will be understood that these wings may be square and stop at the bottom edge of the casing or even thereabove. In this construction also the wings spacing the casing from the eduction pipe will form a plurality of vertical passages between the eduction pipe and casing. H
Referring now to Figs. 6 and 7, 35 designates one of a series of plates each of which is bent up at its edges as shown at 36 and flanged as shown at 37. A series of these platesare assembled together as shown in Figs. 6 and 7 to form an inside member comprising a pipe and a series of radially extending flanged wings 36. The flanges 37 on the wings are riveted to the casing 11 by rivets passing through 'a pair of flanges and the casing. These rivets therefore secure the separate parts of the inside member together and also secure this inside member to the casing. The wings may be further secured together by rivets 38, but for the smaller sizes this is not necessary. The wings 36 preferably taper to their lower ends as shown in Fig. 6. The inside member may be riveted to any suitable riser or pipe 10. As shown in Fig. 6, the inside member thus constructed forms a pipe inside of the casing 10, which pipe is spaced from the easing so as to form a series of vertical passages inside of the casing. The standards 10 are preferably riveted to the casing 11 by rivets which pass through the flanges 37 as well as through the casing. This construction is very simple and at the same time is well adapted for the purpose for which it was designed.
Referring now to Figs. 8 and 9, which show a ventilator of rectangular construction, 40 designates the lobes which are of substantially the same construction as shown in Figs. 1, 2 except that they are adapted for a rectangular gipe and casin The cap is of substantially the same construction as shown in'Figs. 1 and 2, except that it is of rectangular form.
Inall of the above constructions the case ing is held in spaced relation with respect to the eduction pipe to form a series of spaced vertical. passages between the eduction pipe and the casing. These passages will form induction passagesto cause an induced draft upwardly through the eduction pipe. While the caps are not illustrated in the constructions shown in Figs. 2 to 7 inelusive, it will be understood that the same cap may be used as is shown in Fig. 1. It will also be understood that the sleeve damper may be applied to any and all of these constructions. i
It is further obvious that various changes may be made in the details of construction without departing from the spirit of this invention, and it is therefore to be understood that this invention is not to be limited to the specific constructions shown and described.
Having thus described the invention what is claimed is:
1. A ventilator comprising an induction pipe, a cap sustained in relatively spaced relation above said pipe, said cap having an. inverted cone on its lower face, a damper sleeve sliding on said pipe. and adapted to close against said inverted cone for closing the ventilator, and means.constructed and arranged for automatically latching said sleeve'in ventilator closing position.
2. A ventilator comprising an induction pipe, a cap sustained in relatively spaced relation above said pipe, said cap having an inverted cone on its lower face, a damper sleeve sliding on said pipe and adapted to close against said inverted cone for closing the ventilator, and spring latches on said sleeve constructed and arranged for automatic engagement with the top of the induction pipe to latch the sleeve in ventilator closing position.
3. A ventilator comprising an induction pipe, a cap sustained in relatively spaced relation above said pipe, said cap having an inverted cone on its lower face, a damper sleeve sliding on said pipe and "adapted to close against said inverted cone for closing the ventilator, and spring latches on said sleeve constructed and arranged for automatic engagement with thetop of the induction pipe to latch the sleeve in ventilator closing position, said latches having cam faces formed and disposed to ride on the edge of the induction pipe for automatically moving the latches to sleeve releasing position.
In testimony whereof we affix our signa tures in the presence of these two witnesses.
