duplication filed November 25, 192?. Serial No. 235,324.

Air ports or lending fields for flying machines require illumination at night. Becuuse air ports are large the expense ofkee ing them continuously illuminated at night would be large, hence the object of the present invention is to provide means whereby the aviator can, while in flight, bring about the illumination oi the field preparatory to landing and also bring about the extinguishnient oi the light or lights while departing from the field;

According" to the invention there is employed as large hopper adopted to catch a; ball or other suitable object dropped or thrown by the aviator While in. iflig,,h t said ball adapted to actuate e switch that will close the light circuit when desiring to maize lending or to open said eircuit out out the lights after a lending and in flight from the field. Acccrdin to the invention also the hopper itself wiil be permsnently illuminated at night so as to guide the aviator es to the dropping or casting the circuit actuating member when approaching the ield with the purpose of lending A further eeture is the provision st 21 eonstruction he operation which will erdinerily be interfered with or impaired by snow or rain, Ether ob ects t i epeear from the disc osure herein i e f, partly section, erger scale oi bell-receiving is the means actuated the bell.

The hopper can be supported on suitable posts 7 set in the ground, said posts being held in erect position by stays 6 to be anchored in the ground. c

Pivoted upon a shaft 13 in a suitable standard 9 is a lever 14: the free slightly cupped end of which is extended into the tube 11 through a slot 15 therein, said lever carrying pivoted to it a pawl 16. Journaled loosely on the shaft 13 is a ratchet wheel 1'? carrying a switch arm 18 adapted to close an electric circuit through Wire 19 when moyed'onto one of four contacts or terminals 19 placed ninety degrees apart on the margin of a stationary disk 20. The teeth 1" the ratchet wheel are so placed and the movement of the lever solimited that an. oscillation downward of the lever 1 caused by Weight of the bell the tube will eldest e forty-five degree movement of the switch arm 18. Successive ooerations of the iever will therefore cause the alternate closing and opening of the circuit. A spring is shown employed to restore the end ot' the lever 1 to its elevated position Within the tube Where the Weight or the ball w perform the described operation. -When lever 14: is thrown down aster us it can go the ball passes on through the lower end of the tube into at box 12. Such details of equio us may be needed and are not linetrated can be readily supphed by mechanical or electrical engineering shill.

To projec the electric switching mechanism snow and rain is suitably cor-= cred as by e hood I i The rim of tie upper end of the hoo'cer is orovided with e. series of Zero s orote cted from fracture by "wire 9 R:- e lumps can be of difie' t e hopper clear-l distill e A. i 8 lamps can be distinct t i circuit so that they can be let lighted all night. The rim of the hopper is also provided with an inwardly bent margin, as a" (D ciof e bell t nding to bounce uewerd fro: points near the To prevent the be A. from bounding out of the hopper at oth-r points two series of or curtains of chicken Wire netting 26 or oth r materiel can be hung trout cross Wires 2'? 28, subteuding the mouth of the hogs-en The air port or landing field is provided around its boundaries with a suitable numwill drop the ball while in flight to turn on the lights when he arrives at a suitable point duty to extinguish them when he leaves the field which last he can do by dropping a ball into'the hopper after he makes his take oil. If the aviator is to remain in-port he can extinguish the field lighting lamps by manually operatingthe lever 14.

To protect the upper end of the tube 10' from the collection of snow there is provided a hood 32 supported by legs a suitable distance above said end, said hood consisting of a conical or pyramidal member having an upstanding rim around its base, said rim being perforated at 33 todrain it of water when the snow melts. The hood 32 is covered witha conical screen 34 secured to the flange adapted to prevent the ball from loc ging in said hood sand to divert the ball to v the inclined wall of the hopper 10 from which it can fall into the tube or spout. The

switch actuating ball, shown at 35 should, of
