45 its opposite ends connected to said chains;
and a toothed retaining device adapted for
connection to said frame adjacent the links
of the inner stretch of one chain, the sup-
porting means at one end of said chain being
50 adapted to normally force the said -inner
stretch thereof into engagement with saidretaining device, to hold the curtain roller
in adjusted position.
5. In a curtain fixture, the combination
of a horizontal shaft adapted to be mounted 55
at the top of a window frame; a pair of pin-
ions secured to the ends of said shaft; a pair
of spring brackets adapted to be fastened at
their upper ends to said frame below and in
line with said pinions and provided at their 60
lower ends with revoluble elements; a pair
of endless chains connecting said pinions
and revoluble elements; a curtain roller con-
nected at opposite ends to said chains; and
a toothed retaining device adapted for at- 65
tachment to said frame adjacent the inner
stretch of one of said chains, said chains be-
ing normally tensioned, and said inner
stretch normally engaged with said retain-
ing device, by the action of said spring 70
brackets.
6. A window shade support comprising a
pair of endless chains, a rotary element
adapted to be supported at the top of a
window frame and to support said chains, 75
a shade roller, a shade roller bracket car-
ried by each chain for supporting the shade
roller, a pair of leaf springs each having a
bifurcated end, a roller carried by the bi-
furcated end of each leaf spring and engag- 80
ing with one of the endless chains, and a sta-
tionary keeper adjacent to one of the chains
in such relation that the latter is held nor-
mally in engagement therewith by means
of one of said leaf springs. 85
7. The combination in a shade support, a
pair of endless chains spaced apart and
mounted to revolve in unison, a shade roller
bracket comprising a link of each chain, a
tension roller engaging the lower portion of 90
each chain, and . a pair of spring elements
each comprising a support for one of said
tension rollers and combining therewith to
constitute a tensioning device for holding
the chains taut. 95
In testimony whereof I have hereunto set
