SPRING CURTAIN-ROLLER.
Specification of Letters Patent No.i12,881, dated May 15, 1855.
Be it known that LfBENJAMiNB. WEB- and `useful Improvement in'Curtain-FX- `tures; and I do hereby. declare that the following is a full, clear, and eXact description ofthe saine, referencebeing had to the ac- Lconipanying `drawings and to the letters of reference marked thereon, iin which drawis a front` elevation represent- .i "Qing the curtain partly rolled up. Fig. 2, is
U y la plan view of the same. Fig. 3, is a section `fthrough line w, @showing the spring (a) by which the curtainisirolled up,a similar spring of lesswidth "is in this oase: applied also to the opposite end of the roll. Fig. 4c,
is a section through `line it, showing the roll (b) and the `friction spring (c) pressing againstthe rollandfwhich is in this case placed within the` bracket which supports fthe right hand end of theroll y My improvement consists in `the'simple `means `for governingthe action of the acl "tuating spring (a) andrendering it eiiectual to roll the curtain to anypointdesired and..
to check; orhold thesame at will. The
\ wgeneralappearance of curtainiXtures is much the same asothersthe roll (7J) being i supported by `a braoketivat` each end which bracket may or may notcontain the spring y (a) which rolls the curtain. y
The friction spring (c) 's in this `[oase placed within the i right handUbrac-ket and v y presses against the `roll (b) soas to produce `friction sufficient to prevent said roll from turning except when the curtain is drawn by force of the hand the `lower part of this spring protrudes through the lower part of the `bracket and toit is made fast the cord Now when the hand is applied to the cord (e) or the curtain so as to draw it down the spring (a) is compressed and will recoil and thereby roll the curtain up whenever the friction of spring (c) is relieved, which may be done by drawing cord (d), in part, or entirely sothat the curtain may roll up partway, more, or less, or entirely as the case may require, various forms of the friction spring (c) maybe adopted with equal advantage in this combination. My improvenient isequally applicable also when either of the well known forms and arrangeinents of the spring for rolling up the cur- `tain is used.
i I do not claim stopping the curtain when rolled up o-r partly so by means of friction `merely asl that is done in ways not new.
with and operated by a cord (t) so as to stop the rolling up of the curtain or to cause the `same to roll, or to hold the same at any point required, substantially as set forth.
