I have illustrated'acommonly used typeof flare asthalightsource and a commonly employedired signal lamp as :the :warning signal,- because they arelstandardized items in common use. For convenienceof.expression -the term light .fiare." will b'e-used in:a generic. sense,,. to :c0Ver,1ight sources of: varied charactersand the: expression: signal lamp will likewise be used herein to cover varied typesof warningilamps; it2-being1.understood that the specific construction shown in the drawings is merely illustrative.

Among the more importantobjects of. my invention are the following? the provision ofan arrangement for securing eitheral'ightflare ora warning signal, or" both; to=a barricade so that the warning signal and the light source are maintained. ataelevel above the. top of the barricade; the: provision of a simple andeinexpensivel arrangement whereby the securement can be effected quicklyandeasily'withoutthe use of tools and more particularly oisuch arrangement" which permitsoffthe readyremoval ofthe flare; lamp or both for storage or for use elsewhere; the provision of an arrangement whereby the lamp and rolaim.

Theelement I5. is intendedstorepre'sent'a source of illumination.- It is showrn as: a conventional flare whose shape-resembles at s 'aheric'al bomb. The lower portion-1 B of? the-bomb iszgenerally comprisedof: lead v to maintain: the fiare:-upright;:..the illuminating fluid being; contained within: the fluidcontainingspace above tliis loadedbottom.

'The elemen't- -1 at the- 'tbp of the' flare the burner: head throughwhicir the'fluid or gases es cape and 'whichiwhen ignited, :provide the: desired intensity: of illumination"; Thevelement' z'fl is'rin tended to represent: a luminous warning; signal. This warning: signal is? shown as aw conventional lamp whichiemitsmedi light; Any other type may be-emp'loy'ed;

My "invention contemplates tha't theflares'w and lamps be integrated with means" whereby either or both can be? associated with the top b'ar lflwof the barricaderiinea i manner? and by an arrangement whereby; the? general :1 obj ectsi'of my inven tion-are'att'ained,

Reference -isinow made" to; Fig" 2 6f the draw ingsawh'ereirf a'" flare; is? shown? asseiiibieu with a bracketmember: comprisedi of two walls 30) and 3| whicheextendidownwazrdly from a top or base wall: 32;" preferred' form; tlie'se three wall pnrtions are arranged at right angles to each other: andrit? Willhere 'bebpointe'd out that tiieir lengthis no g reatercith'air that of the-outer enjd pcrtions lz 'of me tbp bar; The top facets-the base or top wall 32 of the bracket forms a seat to which the flare I5 is secured. This securement is illustrated in the drawings as availing itself of the fact that the lower half of the flare is comprised of the lead loading so that a threaded opening 33 can be formed vertically upwardly through its bottom to receive a headed threaded member 31 passed through an opening 36 in the top or base wall 32 of the aforementioned bracket. This arrangement is preferred where it is found advisable or necessary that the flare be made readily separable from the bracket to which it is secured. Where it is preferred to make the securement of a permanent nature, the threaded opening in the flare and the opening in the base 32 of the bracket and the screw 31 can be dispensed with and the securement effected by welding the bottom-most part ofthe flare to the top surface 32 of the bearing. a

It will be understood-that in the illustration of Fig. 2,-the showing of the flare l5 is intended to be illustrative also of an integrated unit wherein a luminous warning signal such as lamp replaces the flare-I5.

The dimensions of the cross bar 0 of the standard horse are fixed and I will here point out that the preferred form of my invention contemplates that the spacing of the walls 3|] and 3| be predetermined so that the bracket can be engaged over either extension l2 and when so engaged will bring its side walls and 3| in close engagement with the adjacent faces of the extensions. Some of the features of my invention may be attained by so devising the parts that the walls 30 and 3| frictionally engage the extensions H to maintain the flare or lamp assembly engaged with the cross bar It! to prevent accidental separation. To this end the sheet material of which the bracket is formed may be of a gauge so that it is slightly yieldable.

I will now describe the provision of alternative or additional means for preventing the separation of the flare or lamp and bracket assembly from top bar If]. These means comprise openings 34 and 35 through bracket walls 3| and 30. These openings are in transverse registration. These means also comprise the transverse openings l3 through the top bar extensions l2. These openings are so located that the openings 34 and '35. can be registered therewith. The elements are all preferably so dimensioned and located that when openings I3, 34 and 35 are brought in registration the inner end faces of the brackets will engage the outer end faces of the legs and the outer ends or edges of the brackets will terminate at or short of the end face of the bar extension [2 to which the flare or lamp is affixed. These additional securing means comprise also the pin shown in Fig. 3. This pin is headed at 43 and is of a diameter to be received through the registering openings I3, 34 and 35 and is of such length that when so entered with the head 43 engaged against the outer face of either wall 30 or 3| of the bracket, the unheaded end of the pin will extend beyond the opposite wall for a substantial distance as shown at 45 in Fig. 1. These extending ends 46 of the pins are each provided with an opening 48 diametrically therethrough. These openings 48 are positioned at the same distance from the pin head 43.

These openings 48 in the pin extensions serve with the locking rod now to be described, for locking the flare lamp or other signal device against theft. This arrangement contemplates that when the flare or lamp and its associated bracket is afiixed to the transverse bar as set forth, with the pins 40 engaged through the registering openings, the pins are free to rotate so that their openings 48 can be brought into alignment so that the "longitudinally "extended rod 50 can be engaged therethrough. This rod is enlarged diametrically at one end to provide handle 5| which serves additionally as an abutment to limit the insertion of the rod.

The length of the rod 50 is preferably less than that of the cross bar. This length is however suflicient so that the other end 53 of the rod 50 will extend beyond the other pin 40 when the rod 50 is engaged through the openings 48 with the enlargement 5| in abutting relation to the adjacent pin. This extending end 53- is {shown provided with a diametrical opening 55*therethrough so as to receive the hasp 56 of'ke'y controlled lock 51 to prevent theft of the flares or lamp.

Upon reference to Fig; 1, it will now-be ob-' served that the arrangement thus shown provides a length of the rod which lies in between the two spaced apart'pins 40. This length provides a support for additional signal devices, one of which is shown at 60 in Fig. '1; The arrangement disclosed supports these additional devices in a theftproof manner.

The chain 6| shown in Fig. 1 and hitherto not referred to, is conventional with the type of flare illustrated in the drawings and serves as the medium with which tolift or carry the bomb. The ring at the end of the chain when engaged over a nail or other supporting means serves as *a hanger during storage. I
