rlhis invention relates to curtain fixtures,
but more particularly has reference to the grooves at the sides of the window casing and Y to the parts of the head of the fixture that .track within said grooves. Y
i The invention, broadly speaking, consists Y in making the grooves V-shaped', and in making the shaped. v
This invention relates to that class of curtain fixtures that ernploy elongated heads parts that track therein also V- that track within the groves at the sides of the Vwindow casing, these heads being either solid or provided at their extremities with rollers and intermediate of said rollers with Figure l is a sectional broken view sirnilar o Yto the section portion of Figure l, but showing the rollers operating within the bottoni of the V-groove in advance of the cam- ,Figure 5 is a section atthe line 5 5 of Figure 4f, and
Figure 6 is a section at the line 6 6 of Figures. Y
' Similar numerals of reference denote like parts in the several figures of the drawing.
It is not necessary to describe the construction of the main portion of the curtain liz@ ture in much detail and the saine will therefore be briey referred to.
l isy a hollow bottoni bar made of an integral piece of spring metal whose edges are at the top of the bar and between which edges the lower part of the curtain 2 is suitably clamped. 3 are end blocks which are secured within the bar l near the outer ends thereof in any suitable manner, and l are what will be termed shoes that are elongated and that have threaded sleeves 5 which Y CURTAIN FIXTURE Serial No. 412,630.'
extend inwardly therefrom and are driven upon threaded posts 6 that project outwardly from the blocks 3.
7 are blocks that are slidably disposed within the bar l in spaced relation to each other and also to the ends blocks 3 and these blocks 7 are in the central zone of this bar l.
8 are brake rods which extend loosely through the blocks 3 and 7 and preferably have pinch bars 9 secured at their inner extremities and extendingoutwardly through suitable openings 10 in the bar l so as to be readily available outside said bar.
rlhe outer ez'ztreniities of these rods 8 are bent at right angles as shown at 11 and contact cams l2 which latter have lower tail projections 13 that are pivoted within the shoes at liL so that these Canis are capable of rocking outwardly and inwardly from these pivotal points ll and these rocking movements are brought about by outward and inward movements of the rods 8 in the 1nanner presently to be described.
Jaround these rods 3 and confined between the blocks 7 and collars l5, that are rigid on these rods, are coil 'springs 16, and it will therefore be readily understood that if these blocks 7 are held stationary, these springs will force the rods 8 outwardly, and will cause the Canis l2 to bear with more or less force against the sides of the window casing.
l are V-shaped grooves which are niade of nietal and secured to the sides of the window casing. i
ln the construction shown in section at Figure l and in cross section at Figure 3, the cam 12 is V-shaped on its face and is urged by the resiliently acting rod 8 into the bottoni of the if-groove.
it the extremities of the shoes a are journaled rollers i3 which, in the construction shown at Figure l are in the immediate rear of the V-shaped face of the cani, and these rollers track against the V-groove along the sides thereof, so that it will be clear that, 9
with the cani within the bottom of the Vl -groove and the rollers contacting the sides thereof, there can be no rattling of the iX ture.
Referring to the construction shown at F1g Vure 4, the rollers 18 have V-shaped faces and track within the bottom of the V-groove, while the cam has a stra-ight face andis urged by the resiliency of the rod 8 against the sides ofthe V-groove and away from the bottom thereof, so that in this construction also there can vbe no 'danger of the rattling of `lthe fixture. e
It is therefore immaterial whether the cams are V-shaped andjoperate against the bottoms of the. J-groove or whetherthe rollers are V-shaped and operate against these'bot-` toms, so long as eitherthe rollers or the' cams have contact against the sides of the groove.
The cams will hold the fixture in any desired elevation whether the Contact iswith the bottom of the V-groove or the sides there- '4 operated. Y
of, and the rods 8 will-always act to bind t-he cams against that part of the groove with which they contact, and when these rods are relaxed by forcing the pinch bars together,
this willfrelieve thecams from the tension of the springs andthe fixture can be readily vBut the pinch bars, as isusual inxtures of this description, are not really necessary,
since the bottom bar may be elevated and y lowered without the-operation of pinch bars,
although the'latter are desirable. It will rbe obvious from the foregoing description ythat the gist of the invention rests Y in the broad idea of the V-shaped grooves devices carried by the shoes and contacting simultaneously with the bottoms and sides' of saidgrooves, so as to hold the fixture firmly A f at the sides of the window casing and the as against lateral movement and consequent rattling, and therefore it will be clear that the shoes which track in these grooves can be either vsolid and provided with V-shaped VexternalV surfaces that i engage Within the grooves or said shoes Vmay be providedwith the rollers vand Vpivoted cams as heretofore Y describedwith the contacting surfaces of said rollers ory cams V-shaped for the purposes hereinbefore set forth, and thereforel the invention is not limited to any particularstyle v 'of shoes.
