This invention relates to a combination electric fan and fixture for ventilatin and illuminating cars, such as railway Pu lman cars and elevator cars. It has for an object to provide an improved fixture which will combine a ventilating fan and fighting device in one structure which may be mounted in Iposition with a single mounting means.

t is also an object of the inventlon to provide a device which will have an improved ventilating effect, and in which the ventilator will also act as a cooling means for the lighting device as well as for the operating means of the ventilator. v

With the foregoing and other objects in view, the invention consistsin' certain novel features of construction, combinations and arran ements of parts as will be more fully described in connection with the accompany drawin s.

Fig. 7 is a horizontal sectlon looklng toward the bottom of Fi 6, thesection being substantially on line 7-7 of Fi 6. I Referring to Fi s. 1 to 5 t e side walls and ceiling of a Pu an car are shown diagrammatically at '10 and 11 respectively, with ventilating openings 12 in the side walls for admission of air, the details of construction of the car, screens and so forth'for these ventilating-openings are not shown as they form no part of my invention. My improved combination of ventilating and lightingfix- K ture comprises a substantially conical base and deflector 13 above which is mounted a fan 14 arranged to force air downwardl to the surface of the deflector, as indicated by the arrows in Fig. 1, so that this air is forced laterally and-downwardly in all directions.

to ventilate all portions of the interior of the car and to widely diffuse the stream ofmove ng air so that it will not .be concentrated or discomfort to any passenger. The fan is operated by a motor 15 mounted within the deflector 13 which motor is operated by any means usually an electric motor from any suitable source of electric current, indicated at 16, and controlled by any suitable switch, not shown. The deflector 13 is open at its lower side and has an inwardly extending flange 17 by which it is mounted on the supports 18. This support comprises a plurality of depending elements secured to the ceiling of the car and extending radially inwardly under the deflector 13 andsecured to'a common centralelement 19. The flange 17 rests upon these supports and is secured thereto by any suitable means, such as the bolts 20 The upper end of the deflector 131s also open 7 or admission of air from the fan for ventilating and cooling the motor 15. This opening is indicated at 21 and may be surin any one direction tocause inconvenience rounded by an inwardly extending flange 22 to the inner and lower side of which are secured the depending supports 23 which may be secured to the flange by any suitable means, such as the screws 24. The motor vmay be mounted on these depending-supports by any suitable means, it being preferred to extend the lower end of the members 23 under the lower end of the motor housing, as shown at 25. This housing has a series of inlet ,openings 26 at its upper end with similar outlet openings 27 at its lower end so that airpass ing inwardly th'rou flow downwardly through the motor-housing, as shown by the arrows in Fig. 5, and "revent overheating of the armature and coi The I air issues from the motor housing into the interior of the deflector 13.

My im roved combination fixture also includes a ome light which is mounted below the deflector 13 and the supporting means 18. The base and reflector 28 is mounted at the lower side of the deflector and the support 18 and is enclosed within a ring base 29 these elements bein secured to the support by the bolts 20, and erefore, these bolts mountboth the ventilatin device and the dome light on the supports 8. This is the preferred con- Stl'llCtlOlld although separate means may be employe for securing the dome light to the support from that employed for the ven t1- lating device. The dome structure may 1nclude the usual swinging glass dome 30 hinged to the base ring 29 at 31 and detachably secured thereto at its opposite edge by any suitable means, as a screw 32, to permit the dome to be dr iplped down to give access to the lamp 33. s arrangement gives a very com act, neat and attractive construction whic has the combined features of ventilatin the car and also illuminating it. The air w ich flows through the motor into the deflector 13 passes out throu h the slot 34 between the base 2829 of the ome light and the base of the deflector 13, the slot being provided by the spacing of these elements by the supporting. elements 18. Air, therefore, flows over the base and reflector 28 and prevents overheating of the same.

In Figs. 6 and 7, I have shown the device as applied to the ceiling of an elevator car. Here the walls of the car are shown diagrammatically at 35 and the ceiling has an opening 36 thereln. Mounted in this opening are the supporting elements 38 corresponding to the supporting elements 18 shown in Figs. 5. They are secured to the ceiling o the car, extend radially inward and are attached to the central element 39 to give a more rigid construction. The ventilating and dome li ht construction is the same as that shown in Figs. 1 to 5, the deflector 13 of the fan being mounted on to of the supports 38 the same as in the first orm and the dome light being mounted on the lower side of these supports the same as in the first form. The space between this fixture and the sides of the opening 36 may be covered with a suitable screen 40.

This ventilating and lighting device 0 erates' the same in this arrangement as in t e first form,'the fan forcing air downwardly a ainst the deflector 13 by which it is deflected ownwardly and laterally in all directions through the screen 40 into the car to ventilate the same, while the dome light provides the nry illumination.

It will be obvious from the foregoing description that I have devised an improved com ination ventilating and lighting fixture which may be assembled, sold and installed as. a structure, has a neat and attrae 1 and.

tive appearance, provides ventilation for all parts 0 the interior of a car without concentrating a stream of air in any given direction, and therefore, will not cause an discomfort to the occupants of the car, .andte flow of air prevents overheating of the motor and the elements of the lighting fixture.

Having thus set forth the nature of my invention, what I claim is:

1. In a device of the character described, a substantially cone shaped deflector, a fan above said deflector arranged to blow air downwardly against the surface thereof, a motor for operatin the fan, a base for a dome light 'mounte belowsaid deflector, a su port for mounting the deflector and base ad acent the ceiling of a car, and means for securing the deflector and base to the support.

2. In a ventilatin and li hting fixture of the character descri ed, a su stantially conical deflector a motor mounted within the deflector, a fan above the deflector operated by the motor and arran ed to force air downwardly againstthe de ector, a sup ort for the deflector capable of mounting it rom the top of a car and extending below the lower end of the deflector a dome hght mounted on the lower side 0 the support, and common means for securing the deflector and said dome light to the support.

3. In a ventilatin and li hting fixture of the character descri ed, a su stantially coni-' cal deflector, a motor mounted within the deflector, a fan above ,the deflector operated by the motor and arranged to force air downwardly against the deflector, said deflector being provided with an opening at its upper en for entrance of air from the fan to the interior of the deflector, a dome light having a base mounted below the deflector,

and a support for the deflector and the dome light extendin between them and holdingv relation for exit of the airy.

them in s ace from the interior of the deflector.

4. In a ventilatin and li hting fixture of the character descri ed, a su stantially conical deflector, a motor mounted within the deflector, a fan above the deflector operated by the motor and arran to force air down wardly against the de ector, said deflector being (provided with an opening in its u per en for entrance ofjair from the fan, t e

motor being mounted in alignment with said a ventilating and lighting fixture of the character described, a support oapableo f the defle'ctormounted bein secured to the ceiling of a car and depen ing therefrom, a substantiall conical deflector carried by the support, a an above to rotate in a horizontal plane and force air downwardly against the deflector, a motor for operating the fan mounted within the deflector, and a dome light also carried by said support and-mounted at the under side of the base of the deflector. i
