`electrical circuit being broken between*` the collar `19 and thehinside of the collar 11. the

ing movement of the collar-"11 isstoppedby y a ring or sleeveof transparent `material may H t `equivalently form a lining; for thesocket `126.11m theposition illustrated in `Figure 1, "the device isin itsinoperative position, the

topof "thebrass tubeA and the underside "'jof the "plate r"18, and the 'fixed collar-19 preventsldepression ofthe knob B and collar 11n When either by rotating the knob to. draw upthe collarll or rotatin `the collar lltdcause itto rise on the kno andleave" v "a clearancebetween "the top of" the'xed `fthefcollar 19, a `clearancethenfexisting be- A tween theunderside of thecollar 13` and the; paitof "the knob immediatelyjbelow it. Inthisldeprehssed position a circuit isconipleted `from thebattery 28 through the contact piece 30,*1amp31, spigot25, tube A, plate 18, and spring 21, when the lightof the lamp loo 1 becomes visible through the openings. On releasing the knob, the spring 21 lifts the plate 18 clear of the top of the tube A and breaks the circuit, and by repeated pressure of the hand on top of the knob and alternately removing such pressure the light can be exhibited intermittently. The knob being held by the user and the free end of the stick pressed against the ground, or against any other rigid object such as a Wall or a tree, the pressure of the hand on the knob causes the knob to slide down. on the tube, bringing the plate 18 into Contact with the tube A and completing the circuit It is 'desirable that the circuit should remain broken during daylight or in well lighted streets-where the exhibition of alight by a pedestrian would be unnecessary. For this vpurpose the collar 11 is placed in the osition shown so as to prevent the knob B rom sliding down the tube under pressure of the hand, so that the plate is keptl clear of the tube A. Thus the control of the lamp by the automatically acting means can` be suspended and'restored at will.

By unscrewing the upper part ofthe stick l from the socket 26 so that the lamp is exposed, and placing the collar 11 in its operative position, the said uplper part can be used as an` ordinary las light or electric torch.

Referring now to Figures 2, 3 and 4, the stick may be of Wood, aluminium, or of any other suitable material and of any desired 'external configuration or ornamentation,

but in the example it is assumed to be a slightly tapering smooth tube of ebonite Whollyor partially lined with brass and lpierced with one or more holes at 32 for instance there may be two circular holes diametrically, opposite onel another and glazed with ruby glass or other transparent material, a strengthening band 40 of silver or other metal being provided at the level of the holes 32 and correspondingly perforated. Instead of two holes 32 there may be three or four of such holes spaced apart around the circumference of the stick. At.

the top of the stick a projecting part of the lining 41 is externally screw threaded and slotted at 42, there being preferably two diametrically opposite slots. -A brass inner. v tube 43 (Figure 3) is provided with ribs 44 to register vin the said slots 42, this tube having at its lower end an internall rcrew threaded sleeve 45 insulated from t e tube 43 by an outer sleeve 46 of insulatin material. An electric lamp 31 is screwed into the sleeve 45 and is in contact with a pin 47 passing through an insulating partition 48, the length 'of the tube 43 being such that when itis in position the lamp 31 is opposite the holes 32. In the tube 43 above thevpartition 48 are two batteries in series 28, 28 and a master switch 50 resiliently supported in its insulator 51 and carried in a holder 52, this holder having at its upper extremity a flanged or overlapping roof 53 which is adapted to make contact with the top of the tube 43, the switch 50 being insulated from the said holder and normally in contact with the upper terminal of the battery 28. A spring 54 confined in the holder tends to keep the switch 50 out of contact with the inner surface of the roof 53. The knob B is internally screw threaded to engage the lining 41, and contains a pin 455, which when the knob is screwed home presses down the roof 53 of the master switch holder against the resistance of the spring 54 to make contact with the switch 50 and lining 41, the 1am 31 being thereby placed Y.in circuit with t e lining 41. At the bottom of the stick is a brass tube 56 in electrical connection with the lining 41, concentric With which tube is positioned a switch member 57 suitably insulated from the tube and electrically connected with the sleeve 45. A spring 58 confined in the detachable brass ferrule normally keeps the switch member 57 from contact with the bottom of the said ferrule, which ferrule however is capable of a slidin movement of small extent in relation tot e tube 56, to which it is attached by a set screw 61 Working in a slot in the said tube 56, so that when the extremity of the ferrue (which may be shod` with iron) is pressed against the ground, the electrical circuit is comleted from the member 57 through the errule 60, tube 56, lining 41, lamp 31, and sleeve 45. This circuit can be broken by loosening or screwin back the .knob B so that the spring 54 disconnects the parts 50 and 53.

Where only one switch is employed, it

vmay be located in the ferrule, the circuit being closed by pressure exerted longitudinally of the stick from the handle towards the ground; or where both an automatic switch and a master switch are employed, the former may be'located either in the handle or the ferrule.

Although I have herein described examples of means by which the objects of this invention can be accomplished, it is obvious that the form and construction of the devices described can' be varied while still accomplishing such objects, and I do not desire to limit my `invention to the exact details describedbutthat it shall be understood to cover 'all such variations as are fairly included-within the scope of the fol-` lowing claims.` n What I claim and desire to secureby Letters Patent of the United Statesis 1. In a walking" stick or umbrella,` a stem` comprising a detachable hollow portion, an

" means can saidsliding movement to-break` said circuit.

` 2: In a walking stick or umbrella, a stem provided'iwith a `.fast 3 collar, an externally screw threaded outer 'collar slidable on said y fast collar, light emittinv means carried by said stem,`a handle slida le onsaid` stem to operate said light'` emitting means, said handle being internally screw threaded `to engage said slidable collar, said slidable col lar being longitudinally `adjustable to 'relstrain the slidingmovement of said handle, e

whereby the operation of said light emitting `be suspended whenso desired. JOHN ARTHUR HAYHGE.
