WINDOW` HEATER AND DRIER.

Specification of Letters Patent.

Patented Mar. e, 1am.

, To allai/1,0m it may concern'.

Be it known that I, ABRAHAM A. FAGEN, a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Window Heaters and Driers, of which the following lis a specification.

In the operation of a vestibuled street car or motor bus conveyance, or any vehicle having a window or wind shield with glass panels'in front of 'the driver, great dilliculty is experienced in stormy weather be cause of the inability of the driver to see clearly through the glass any object or obstruction in the path of lthe vehicle. It sometimes happens in a snow or sleet 'storm that fthe glass in front of the driver will` become so coated on the outside 'that his vision of the track is almost entirely obscured. This is true also of the driver of anA automobile or motor bus. yIt also frequently happens in warm weather during a rain storm |that drops of water will stand on the glass or condensation will accumulate on it to such an extent tha-t other vehicles cannot be seen and accidents frequently happen.

The object, therefore, of my invention is to provide a device by means of which the glass panel of the window or wind shield maybe heated in cold Weather to remove the ice and snow and in warm weather to dry the moisture or condensation thereon.

The invention consists generally inl various constructions and combinations, all asv hereinafter described and ed out in the claims.

In the accompanying drawings. forming part of this specification,

`Fiofure 1 is a perspectlve view of the forwardb portion of-a street car, showing my invention applied thereto,

Fig. 2 is an inside view of the sash supporting my invention,

Fig. 3 is a sectional view on the line 3'3 of Fig. 2, Y A

Fig. 4 is a sectional view on the line 4--4 particularly pointof Flg. 2,

Fi 5-is a detail view-'showing the preferre manner of mounting the heaterand drier onthe sash of the window. f

In the drawing, 2 represents a street car of any ordinary or preferred constructlon. It isprovided withthe usual vestibule 3 and back and forth between the sash erably an upper and a lower sash, the upper one 5 being about -the height of a mans head from lthe floor, so that as the driver stands by the control lever of the oarhe can look through. the kWindows 5 merely by turning his head from side to side. The metal sash or the one through which the driver usually watches the track would be removed in stormy Weather and in place thereof a -sash 6 substituted, having a panel 7 of glass or other suitable transparent material. This sash would temporarily take the place of one of the sash 5. v

A socket 8 for an electriccircuit plug is `mounted on the franie 6 and conductors 9 are secured to the frame 6 which preferably is of wood or other suitable nonconducting material, and extend 'partially around the frame and have .an electric connection with a Wire coil 10 ywhich engagesa hook lil mounted on alplate 12 that is secured to the sash frame. similar plate 12a is secured to the opposite rail of the sash and carries a hook 11 for engagement with the wire and thence the wire 1s carried back yto the starting point side of the sash anfll so on,

rai s.

The other connections of thewire with the Asash bein substantially the same as those describedg; I will indicate them by the same reference numerals. A plate 13 1s secured to the sash 6 at the opposite end of the frame from the plate 12 and a conductor 14 leads from this plate throu ha switch 15 to the socket 8. When, tlgerefore, an electric current plug is applied to the socket 8, the circuit will be closed through the conductor 9 and around throu h` the resisto 'es adjacent without stooping p The circuit may be opened or closed at any timeby the operation of the switch. When this current is turned on, the resistance coil will be heated suiciently so that the radia-V tion therefrom willV warm the glass and prevent the ice or snow from clinging thereto and`will also dry any moisture resulting from condensation which'may be adhermg to the outer surface ofv the glass. The stretches of this resistance coil may be as near together as seem desirablesto produce the best results and it may, of course, be carried back and forth lengthwise of the sash instead of up and down, if'preferred, and in various ways its arrangement of the sash may be modified. v

To protect the hooks and the su porting plate thereon, I prefer to provi e outer guard plates 16 which cover the hooks and the ends of the resistance coil connected therewith and between the inner plates andconcealing the wire I .provide shields 17 consisting preferably of thin metallic bars semi-circular in form, having their ends brazed to the supporting plates on the'sash and partially encircling the coil. These guards serve as a means for protecting the coil from injury or breakage and also serve as deiiectors for directing the heat waves upon the surface of the glass.

I prefer to mount the guards in the manner shown and in the form described, but various modifications therein will suggest themselves to any one skilled in this art.

The main purpose of the invention is to provide a means .for mounting a resistance coil so that the heat therefrom will warm the surface of the glass and dry off the moisture thereon or prevent the accumulation of ice or snow.

I claim as my invention:

1. The combination, with a window sash, of plates securedv to the opposite rails thereof and having hooks thereon, a resistance wire engaging said hooks and extend-ing across the glass from one side of the sash to the other, guards mounted on said plates on the outer side of said resistance wire and concealing and protecting the same, conductors connected with said plates, a socket for an electric lug mounted on said sash and in circuit with) said conductors, and a switch for directing the circuit through said conductors.

2. The combination, with a window sash, of (plates mounted on the side rails' thereof an having hooks thereon arranged in staggered relation on the opposite rails, a resistance wire strung between said hooks and rlying close to the surface of the glass, suitable guard plates for said resistance wire and conductors for an electric circuit connected with the ends of the wire.

In witness whereof, I have hereunto set my hand this 15 day of January, 1919. ABRAHAM A. FAGEN.
