f Whenithe curtain rod is being installed, the .trigger 'is .dropped-to the position shown'in' Figs. 2 and 4 afterthe rods have been spreadV sufficiently. to freely receive thew'find 0Wy carsi Figs. 2 and f4 that the portion 21rthereof will i@ i i ing and the rods are then telescoped together against the casing as shown in Fig. 1, the inclined faces of the teeth 15 riding past the hook 18 and forcing it outwardly. The hook 16 will snap back into each depression between the teeth as each tooth is passed and when enoughpressure has been placed on the rod, the pawl will automatically lock the rod sections in engagement. In other Words, the teeth 15 are saw-tooth shaped so that .the pawl will ride over the teeth when the curtain rod sections are travelingv into telescoping engagement but will lock to prevent the rod sections traveling out of tele-' 15 scoping engagement. g

-By'providing the trigger in the form of a loop 'with the plane of the portion 21, at Y right angles to the plane of the loop, thetrigger will lockitself in theposition showinA in 20 Fig. 4. This occurs because the pressure of thelap l16 against'the portion 21 opposes the initial raising of the trigger, the portion 21 having slightly passed dead center in reaching its Fig.. 4 position.V @The rods A and B include the end arms 22 Vand 23, respectively, the former being attached to j aw members 24'provided with teeth v25toengage the casing. Y

The auxiliary curtain bracket 26 has the Aarm 27 to be received in the open end of the larm 22 and an arm 28 to be received in the open end of the arm 23. A fingerY 29 on the arm 28 extends through ak slot 30 in the arm 23and'locks the rod B securely in engagement with the arm 26. The advantage of this construction lies the fact that the bracket 26 is held in place 'bythe engagement with the casing 10 while the rod Bmay be removed from its brackets without disturbing the rod A. Y- Some changes may be made'in the construction and arrangement of the parts of my invention without departing from the s real Vspiritand purpose of my invention, and it ismy lintention to Vcover by my claims Iany `modified forms of structure or use ofl niechanical equivalents, which may be reasonably included within their scope.

I claim as my invention: i j 1'. Ina curtain rod, a pair vof rod members, one 'ofwhich'telescopes within the other, a 'plurality' 'of lsaw-tooth shaped teeth formed 'on one rod member, a pawl attached tothe `other rod member and provided with axfre'e end terminating in a hook extending through said other rod member and positioned to en- ,fgage o n'e of said teeth and a trigger member having a portion of greater width than thickness interposed between the pawl and the adjacent wall of the rod member to which itis secured, said trigger member being capable of Ajmo'vementto'rotate said interposed portion "-fr'om'a position wherein it holds the pawlA out ''f engagement with Isaid teeth to va position where it allows the pawl to ride against the teeth. Y

2. In a curtain rod, a pair of telescoping rod members, a plurality of teeth Jformed in the wall of one rod member, a pawl rigidly secured at one end to the other rod member and provided with a hook at its free end projecting 'through an opening in said other rod member, said hook being positioned to engage cneof said teeth andthe pawl being of spring material' and mounted to normally urge said hook into said engagement and a trigger in- Vcludiiig a portion interposed between said pawl and a rod wall to which it is attached, said portion being of greater width and thickness andthe trigger ,being movable to rotate said portion from a position wherein it holds the pawl in an'inoperative position to a position where the pawl may Vengage said teeth.

3. In a curtain rod, a pair of telescoping ,.85 rod members, a plurality of teeth formed in the wall of one rod member, a pawl rigidly securedV at one end Ato the'othervrod member and provided with a hook at its free end projecting through an opening in said other rod `.o member, said hook being positioned to engage one of said teeth and the pawl being of spring material and mounted to normally urge said hook into said engagement and means for holding the pawl out of engagement with g5 said teeth, said means'being movable to a position vallowing the Vpawl to engage the teeth. v Y

4. In a curtain rod, a pair of telescoping rod members, a plural-ity of teeth formed in the 10o wall 'of 'one rod member, a pawl rigidly secured latjoiie end to the other rod member and provided with a hook at its free end projecting through an opening in said other rod member, said hook bei-ng positioned t'o engage :.105 one of said teeth and the pawl being of spring materialF and mounted to normally urge said hook into 'said engagement and a loop shaped trigger including a portion of greater width and thickness interposed between the p'awlrno and the wall to which it is secured, the remainder of the loop being positioned in a plane substantially perpendicular to the plane of said portion.

-v5. In a curtain rod, apair of telescoping 5115 rod members,.a plurality of saw-tooth shaped teeth formed, in the wall of one of the rod members, afpawl rigidly secured at oneend to the wall `of the otherlrod member vand proi vided Yat its free YendJ a hook .projecting f'120 .through an opening in said other rod member wall and adapted to vengff'f'e one of said-teeth, the pawl being otspring material and normally urging said hook into' engagement with a, tooth and a trigger including a por- 125 tin of greater width'and thickness interposed between the'pawlandthe wall'to which it is attached, the trigger being 'adapted to be moved to :rotate saidp'ortion from a position holding the 'away' from 'the teeth to a 5130 position where it does not interfere with the engagement of the hook with the teeth.

6, In a curtain rod, a pair of telescoping rod members, a plurality of teeth'ormed in one rod member, a pawl attached at one end to they other rod member and yhaving a free end capable of movementtoward and Iaway from said teeth and adapted to engage oneA of said teeth and a trigger including a portion of greater width and thickness and interposed between said pawl and thewall to` which it is attached, the trigger being adapt'- ed to be moved from a positionwhere said portion holds the pawl away from yContact with the teeth to a position Where ity does not interfere with the contact of the pawl with the teeth. g c

7. In a curtain rod, a pair of telescoping rod members, a plurality of teeth formed in one rod member, a pawl attached at one end to the other rod member andV having a free end capable of movement toward yand away from said teeth and adapted to engage one of said teeth and means `to hold the pawl in an inoperative' position,- said means'being movable to a position where it does notinterfere with the engagement` of the pawl with the teeth.

8. In a curtain rod, a pair of telescoping rodv members, a plurality of saw-tooth shaped teeth formed in the wall of onerod. i

member, pawl of lspring material secured at Vone end to the Wall of the other rod member and free at its other end to move from a position engaging said teeth to a position out of engagement with said teeth and a trigger f including al portion of greater widthy and thickness interposed between the pawl and the wall to which it is secured, said trigger being movable from -a position wherein the* pawlengages one of said' teeth to a position wherein the pawl is out of engagement with any of said teeth.
