CURTAIN-ROLLER. e
` speeieeation of Letterratent No.71a524, dated March 13, 1855.
Be it known that I,FREDER1CK W. URNN,
` `of SaXonville, in thecounty of `MiddleseX and State of Massachusetts, have linvented j `a new `and, useful Improvement in Curtain f f or lVindow Shade Fixtures; and `I jdo here f by `declare that thesame :is fully described "andrepresented in theollowing speciicationand the accompanying drawings, letleters, figures, andxreferences thereof. j
Of the said drawings, Figure l, denotes a front view ofa curtain or window shade having my improvement. i Fig. 2, a vertical and longitudinal section of thecurtain roller and thebrackets"which`sustain it.l
The nature of myinvention consistsin providing one of the brackets with a circular chamber or recess for the reception of f one of the heads of the `pulley of the curtain i roller and so that suchY head `may be inserted inw-the rim and havef its outer surface s0 i H j buriedwithin the recess that the cord wound onth'e pulley can by no possible means get between the pulley and the bracket.- In the drawings,l denotes thecurtain' roller, and B and C, `the brackets by which i itis sustained. l
In the bracket,.B, acylindrical scckeuu,
`is made for thereception of one end ot the rollerand to allow such end to freely rej volvelwithin 'such` socket. `The opposite end of the roller `is'provided with the sheave pulley or grooved roller, E, which is made i in the usual way `with itwo heads, c, CZ, and that endof therollerto which it is attached l carries a yielding journal, e, l that rests against and is pressed outward b-y a spring, f, imbedded in the curtain roller.
. The bracket, C, is madewith a cylindrical chamber or recess, g for the reception of the head,` d, of the pulley B, and of adepth somewhat greater than the width of the said head, d. HThis recessbrchamber has a socket or bearing, h, made axially from it and in the bracket, such bearing being for holding and receiving the yielding journal, which, when placed in it is borne against its end so as to crowd and keep the other journal in its socket.
e In order to remove the curtain roller from the brackets it will only be necessary to press it :toward the bracket, C, so as to force the `yielding journal back into its socket in the roller and far enough to move the other journal out of its socket. This done, by drawing the roller outward, it may be removed e from its brackets. n
By inserting the head of the pulley within a recess or chamber in the bracket, there is no chance for the cord of the pulley to get caught or pass between the bracket and the headof the pulley, the pulley head serving to` keep the cord from chaiingagainst the bracket. By means of my improvement, I `am enabled to make the curtain of greater width than it can be when the pulley head is Vnot inserted in the bracket.
I do not claim the inserting of the end or journal of the curtain roller in a chamber gr bearing in the socket that supports it, ut
What I do claim is FRED. W. URANN. Witnesses:
R. H. EDDY,
A. LEDENTZ.
