vApplication :tiled September 1Q, A1932. Seria 1 No.n63v2,5l68.
This invention relates to curtain rollers of the hollow sheet metal type, and is particut larly concerned with the way in which the inner end of the torsion spring is fastened to the roller.
Heretofore it has been the practice to use a bung of some sort for this purpose, with the bung grooved out along one side to interfit tion -issusceptible ofineorporation in othery with the seam on the inside wall of the roller. In such constructions, the bung has represented an appreciable part of the cost of the roller and has required some time in which to properly fit the same.` v
The object of the present invention 1s to provide an improved torsion sprlng anchor, in the form of a small plate, which is very ineX ensive to produce and easy to apply and will serve the purpose just as well if not better than the more complicated spring anchor age devices used in the past.
In order that the invention may be .readily understood, one particular structural embodiment of the same is presented herein, butit will of course be appreciated that such embodiment is intended primarily for the purpose of exemplification and that the invenstructurally modified forms coming equally within the scope ofthe appended claims.
In the accompanying drawing: Fig. 1 is a face view of a window curtain'assembly showing the roller equipped withLthe improved spring anchor;
Fig. 2 is a longitudinal section through the spring end of the roller; and j Fig. 3 Vis a transverse section through the roller, showing the anchor in end elevation.
` As will be observed in the drawing, thev roller, which is designated by the numeral 10,
is of hollow sheet metal construction and is journaled in a pair of end brackets 11 `and 12. The spring end of the roller contains a short spindle 13 which is rotatably mounted in an end bung '14 in the roller vand is provided withy a flattened end 15 which fits non-rotatably in a conforming slot 1G in the adjacent end bracket 11. The other end of the spindle extends into and is secured to one endof a long coiled Y torsion spring 17, spring l17,instead ofbeing attached to the The'farend of the usual 'anchoring bung, is hooked through two i spaced apertures 18 in the adjacent end of a v curtainV holding-,groove 22' in the roller, pro- .i
devicecosts practically nothing to make'and may be assembled quickly with the'roller in properly interlocked association with the latter by mere insertion ofthe 'plate without any regard to itsl position, the action of the spring 17 'when wound serving to ybring the edges of the plate into engagement with the formations 21 and 22 on the inside ofthe roller.
vI claimt: f j
1.V Incurtain roller construction, a hollow Sheet metaly roller of generally circular cross section having an inwardly projecting seam formation on the inside thereof, Va spindle in one end of the roller', aspring attached to the spindle, and aplate attached to the spring sof and positioned in the roller diametrically of Y the latter with one of'thesid'e edges of theplate held by the torsion of the spring against said inwardly projecting seam formation.
' 2. In curtain roller construction, a hollow sheet metal roller of generally circularcross section having an inwardly projecting seam t formation onthe inside thereof, a spindle in fone end of the roller, a spring attached to the spindle, and a plate attached to the spring .and positioned in the roller diametrically y of the latterl with oneof the side edges of theplate held by the torsion of the spring l against" said inwardly projecting seam for' mation, said plate` being provided atone of its ends with apertures, and said spring hav-l ing its adjacent end hooked through lthe apertures.v Y f 3. In curtainroller construction, a hollow sheet metalvroller of generally circularcross section having an inwardly projecting seam formation on theinside thereof, a spindle in one end of the roller, a spring attached to the spindle, and a plate attached to the spring and positioned in the roller diametrically of the latter with one of the side edges of the plate held by the torsion of the spring against said inwardly projecting seam formation, said plate being a rectangular mem# ber of slightly less width than the inside diameter of the roller and being provided at one of its ends with apertures, and said spring j having its adjacent end hooked through the apertures. y -1 i l5 .4. In curtain roller construction, a hollow sheet metal roller of generally circular cross section havingan linwardly projecting seam formation on the insidev th-ereof, a spindle journaled in one-end of the roller,v a spring connected atene of its ends to the spindle, and a sheet metal stamping connected to the other end of the spring, said stamping being provided with a plurality of longitudi` lnally extending parallel. supporting edges which are spaced apart far enough to engage against the'inside of the roller and center the stamping within the same, and one of said supporting edges on the stampingbeing held in lateral abutment withv the seam formation by the torsion of the spring.l
lIn testimony whereof I have hereunto subseribedmy name.
