COMBINATION ELECTRICIAN AND Lam.

To all whom it may concern: 7

Be it known that we, RALPH W. ARM- s'rR'onG, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, and WIL- LIAM S. Evans, a subject of the King of Great Britain, residing in Rosebank. county of Richmond, State of New York, have invented a new and useful Improvement in Combination. Electric Fans and Lamps,'of

-which the following is a description.

This invention relates .to apparatus for producing light and air on railroad vehicles, and has particular reference to a combination of means whereby an electric fan and an electric light are associated so as to practically concealthe fan and make the apparatus appear merely as an electric light fixture.

Among the objects of our invention may be noted the following: to 'provide'a fixture so constructed as to support electric light parts and conceal therein an electric fan; to provide means for combining light and air producing apparatus for use particularlyon railway vehicles; to provide a combmation fixture having the lightand fan parts so arranged as to avoid interference of the same with each other and have the appearance of a light fixture only; and to provide a simple. compact and effective structure by means of which a light fixture may be utilized also as a fan fixture, and by means of which the air can be deflected at the proper an le in "the vehicle.

With the above objects in view, and others which will be detailed during the course of this description, our invention consists in the parts, features, elements, and combination of features and elements, as hereinafter described and claimed.

In order that our invention may be clearly understood, we have .provided drawings wherein:

Figure 1 is an elevation of a structure embodying our invention and shown as attached to the ceiling and roof of a car, the parts of the latter being shown in section; and Fig. 2 is a sectional elevation taken vertically through Fig. 1 and showing the details of construction embodying our invention.

Referring to the drawings, the numeralr 1 Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed May 23, 1913. Serial No. 769,365.

- indicates the ceiling of a railroad vehicle such as a Pullinan dining-car, 2 being the roof of said car. The ceiling may be concomprises the circular support 3, which is angular in cross-section. The horizontal portion of the support has a plurality of lugs or projections 4 which are slotted for the reception of bolts 5, pivoted at 5, and the free ends of which are screw-threaded and also headed at 6, the screw-threaded portions carrying winged nuts 7 which engage thenotched flange 8, of a dome or cover 9, which encircles the support 3, and is securely fastened to the'latter by the said bolts. To make the parts dust-tight, a rubber gasket 10 is arranged between the horizontal portion of the support 3, and the top surface of the roof 2, and another rubber gasket 11 is arranged between the upper edge of the vertical portion of the support 3, and the horizontal flange of the dome 9, the latter being grooved to receive said'gasket 11, and'the said upper edge of the support. Another annular angular support section comprising the depending member 12, horizontal member 13, and upwardly-extending member 14, has a plurality of preferably hollow bolts 15, extending upwardly therefrom, which are rigidly secured to the member 13. and pass through th ceiling 1, roof 2, gasket 10 and horizontal portion of the support 3. The bolts are headed at 16, and have a screw-threaded portion to which is applied a nut 17, for holding the upper support section 3, in fixed relation, and thus within the member 3, as clearly shown in Fig. 2'; and in said figure it will also be seen that the gasket 10 extends into engagement with said sleeve 18. The upper edge of the member 14 affords a seat and support for the flange 19, of the casing of an electric motor, which is' thereby suspended within the two upper support sections and shielded by the sleeve 18, and the head of which motor projects upwardlyinto the-dome 9 of the superstructure. The motor-shaft 20 depends considerably below the lower edge of member 12, and has securely pinned to its lower end'the hub 21 of a fan, the blades of which latter will be presently described. Rigidly secured, as by screws 22, to the depending member 12, is" a metal filigree or open-work hoop or ring 23, the same being arranged to encircle the member 12 of said fixture and .depend a short distance thei e below. An ornamental flange 24 may be applied to the ring 23, above the top thereof,

as by screws 25, and arranged so as to encircle the support member 12 'close to the ceiling 1 of the car. Secured to a flange 26, of the ring 23, is another annular support section 27, the horizontal flange 28 of which is grooved to receive the lower ed e of the ring 23, thus making a neat and tight joint. The section 27 is provided with the curved, depending, inwardly-extending arms 29, which are preferably made U-shaped both for strength and to receive the electric circuit wires of a subjacen-t lamp. The curved arms-29 are connected at their lower ends with a circular flange or ornamental portion 30, to which is secured the horizontal flange 31. of the socket-support 32, of the lamb, said support being externally screw-threaded and having a central web 33, to which is securedthe socket 34, for reception of the lamp-plug 35, supporting the usual electriclight bulb 36. v

The socket-support'32 has secured to its lower end the resilient shade-holder 37, the lower ends of the members of which are conformed to the shape of the flange of the shade or globe 38, so as to securely hold the latter when compressed into engagement therewith by the clamp 39, having the interior screw-threaded flange 40, cooperating with the external screw-threads of the socket-support 32. The leads 41 to the electric bulb extend in one or more of the arms 29, being housed and concealed by the latter, as clearly shown in Fig. 2. The bolts 15 may be utilized to convey the leads to the lamp and house the same, as shown by full and dotted lines at the point 42, at which point they leave the tube and are supported.

The hub 21 of the fan is provided with a plurality of obliquely-arranged, curved, radial blades 43, the lower ends of which are secured together by means of a plate 44, secured to the flange 45, of the hub 21, and the upper ends of which are secured together by a similar plate 46. Extending laterally from the plate 46 are a plurality of arms 47, each of which supports a fan-blade 48, extending radially from the fan-blades 43, and at an angle thereto. As shown in the drawings, and particularly Fig. 1, the blades 43 are arranged circumferentially of the shaft 20, radiate from the latter and are curved longitudinally. These fans are. also arranged vertically oblique with reference to the shaft 20. The fan-blades 48 are arranged substantially in a horizontal plane and slightly at an'obtuse angle to the ends of blades 43, and also arranged vertically oblique, with reference to their transverse diameter, to the shaft 20. To this particular arrangement of the two different sets of fanblades we do not desire to be strictly limited, as 0,! 1; inventionincludes any fan blade arrangfment which will result in drawing air into the chamber above the fan through the air admitting filigree ring 23, or substantially in the direction of the arrows a, Fig. 2, and then deflect said air downward and outward through the support or casing openings between the casing arms 29, and substantially in the directiomof the arrows b, Fig. 2. In other words, this important feature of our invention involves an idea of means by which air may be drawn into the chamber above the fan and then deflected by the fan at an angle of substantially 45,

this angle being conceived by us to be an approprlate angle of distribution of the air above the heads of passengers, for example,

properly distributed below the ceiling of a car or other vehicle and above the heads of those seated therein in such manner that they may not be exposed to direct injurious or disagreeable air drafts. The structure of fan described and shown has been found by us to satisfactorily carry out our ideas of invention and we have, in consequence, illustrated the same as thebest disposition of parts as we now contemplate making our invention without, of course, being limited to the precise angles for the fan-blades shown in the drawings.

From the foregoing it will be seen that wehave provided an apparatus by means of which the ugly fan feature is eliminated, since the fan is practically invisible. At the same time, we have combined the .merits of the fan with the light without destroying the merits of the lamp and while assuring the 'sightly and ornamental appearance of the whole apparatus.

It is believed to be new to make a combined fan and lamp comprising a support or casing, an electric motor sustained at the upper part of said support or casing, an electric lamp sustained at the lower'part thereof, and a fan arranged in an intermediate chamber of the support formed between the motor and the lamp and operatively coupled to the motor, said support or casmg havmg openings forming air passages to and from the fan chamber, preferably.

separate air inlet and outlet openings respectively located above and below the upper plane of rotation of the fan. There also are novel features in the special sectional construction of-the motor and fancasing and in the manner of sustaining the lamp below the fan which in turn is-below the motor which at any time may be conveniently inspected by opening the top or dome of the casing.
