I Beit known' that I,



To dill whom itnuiy concern; s

GEORGE W. yDALLIMomn a 'citizen ofthe UnitedStates,-'-and a resi,-

dent of Pocatello, inthe countyl of=Bannock and State of. Idaho," have invented a-'new and 'Improved Flag or'Signal, of which the following-is 'a full, clear,l and exact description. x Y

This-inventionrelates to flags tor signals railways. The object ofthe invention -is` to produce a flag-,having a pole 'oristail' within which the'curtain or body of the flag' may..bere ceived =Whenthe signal 1- is notv being displayed, and further, to provide a simple construction enabling the iiag to lie-extended orA withdrawn from view. The lnventlon consists' 1n the 'construction and combinationY of parts to bemore fully described hereinafter and particularly set forth in the claims.

Reference is to ing drawings, iication, in which sunilar characters of ref erence indicate corresponding parts inall be had to the accompanythe views, in whichthe stai Figurel shows the pole or shaft of the device substantially in longitudinal section,'

the flag or curtain being represented as broken away; Fig. 2 is a cross -section on the lineV 2-2 of Fig. 1, upon an enlarged scale; and Fig. 3 is a cross section on the line 3 3 of Fig. 1', also upon an enlarged scale, showing the curtain wrapped upon the spindle or staff.

Referring moreparticularly to the parts', 1 represents the pole Vor flag-staff. This pole is provided with a centrally-disposed bore 2, the outer portion of which is lined with a sheath or sleeve 3 of sheet metal or similar The bore at the endo the pole or staff is closed by a plug or cap 4, as shown. The inner portion of the pole or staff 1s provided with a reduced bore 5, which is a continuation material.

at this point is provided with a longitudinal slot 6, which passes through to the bore 5, as dshown in Fig. 2.

Rotatably mounted in the stall", there is provided a spindle 7, the body of which 1s 1n the form of a stick or small stad" mounted centrally in the bore 2. In order to support this spindle, the outer end thereof 1s formed into a gudgeon 8, which is rotatably mounted in the -cap 4. In the inner end of the stick A7 a neck 9 is attached, the said neck being Specification of Letters Tatent. Application med September 1155-1908. SerialfNa geth the neck 9.-has J its Iprovided"with a lbutton 13, having larged head and a-reduced shank 14,'fwhich --shank passes throughfthef-slot (ij-,ias Shownin ."Fig.v 2. iThe *head- 13l isof-lozenge shape,`

forming a part of this speci-` of the bore 2. The upper side of formed preferably of two wires twisted to-v 'er'asvshown One ofthe wires forming end rotatably. mountedfin a socket 10, vformed at the innerend of the the borel 5, .I

receive the-,wires 'of the neck 9. v his nut is andlit v-isrecessed into the outer v,surface of the staff; that is, the stad is, providedwith a-- longitudinal groove or channel v 1.5, ,which lits theunder side-fof the button-,as'indi-` cated.

-KAs findi'cated 1in Fig.- 3, f the bore- 2,-with its sheath 3, forms a barrel in which the Hag properhor curtainA 16, is received, the said flag being' wrapped upon the stick 7, to which it is attached by staples or similar fastening devices 17. This barrel is provided wlth a longitudinal slit 18,` which is lined by extensions or lips '19, formed on the sleeve 2. This slit one side rom'the axis of the stati', as shown in Fig. 3. Through the slit the iag 16 extends. '.From this construction, it will be evident that if the nut 11 is slid longitudinally of the staff, it willoperate to rotate the neck 9,' and the stick 7, which is rigid therewith. In this way, the curtain 16 may be drawn into the barrel, or barrel, as indicated in Fig. 1. The barrel evidently constitutes a protection for the curtain or iag 16 so that it will not become soiled quickly, and in this way it will preserve its original color. It will be evident that different spindles, carrying flags of different colors may be v used with one stad, and they may be readily substituted for each other; or, on the other hand, it will be readily observed that Worn out iags may be replaced by simply removing the spindle, cap and staples.

The neck constitutes a rudimentary screw of high pitch, which can be readily formed without special tools, but it operates efectively to rotate the stick when the nut is moved. The slit 18 is quite narrow, so that the lips 19 lie very near each other and exert a small degree of tension on the flag or curtain 16 as it is being extended or rolled up. This is very desirable, as it tends to keep' Patenteuoet. 26, 1909.'.

18 is disposed slightly to it may be extended from the tial continuation of the curved surface of the staff, as indicated in Fig.`2. In this way the button does not project to any great extent beyond the stati', and hence it is not likely to be in the way.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A Hag or signal,having a stati with a bore therein, a spindle rotatably mounted in said bore, a curtain -attached to said spindle, said stati having a slit through which said curtain may be. extended, said spindle having a neck in the form of mentary screw, a nut receiving said and means fonguiding said nut to slide longitudinally of said staff to rotate said spindle. f

2. A flag o signal, having a staff with a longitudinal-me therein, a spindle rotatably mounted Within said bore,

having a neck forming a rudimentary screw,

said staff a rudineck l l having a slot opposite said neck, a nut engaging i having a lshank passing through said slot and engaging said nut, said button having an enlarged head, said staif having a groove receiving saidheadfand a curtain attached to said spindle, said staff having a slit through Which said curtain may be eX-.

i tend-ed.

3. A flag or signal, having a staff with a bore therein, a sleeve of sheet metal form- I ing a lining for said bore, said stati having a longitudinal slitttherein, said sleeve having lips extending into said slit, and a curtainl mounted lwithin said bore and adapted to be extended througlrsaid slit, said lipsbeing disposed close together, exerted on said curtain, or in being Withdrawn.

In testimony whereof I have signed my i name to this specification in the presence of two subscribing Witnesses.,


wheizby tension is in being extended said rudimentary screw,I a button'
