This invention relates to what is believed to
be a structurally new and novel shade roller

the arrangement is such as to substitute a manu
wound on the roller as seen in Figure 1.

In reducing to actual practice the principles of
' my ideas, I have found it expedient and practica
ble to utilize a pair of similar supporting brackets
provided with ball bearing devices to rotatably
and effectively support the trunnion equipped
ends of the shade roller, whereby to facilitate rais
20 ing and lowering the shade.
The principal feature of the invention is, how
in Figure 6 is formed into a cup I‘! to accommo
date a. notched roller bearing unit 18. The en
trance notch [9 permits insertion and removal
of the trunnion II.
The left hand or opposite supporting. ?xture is
denoted by the numeral 20. This also includes
an apertured attaching ?ange 2| and an out
standing wing or plate 22. As seen to advantage
in Figure 4, the central longitudinal edge por
tion of the plate is formed. into a circular cup 23,
facing outwardly and containing therein a suit
able ball race or bearing unit denoted by the nu
meral 24. This arrangement provides the desired
pull chain having its free workable ends depend
ing in parallelism within convenient reach to fa~
cilitate positioning the shade in the desired posi
tion and satisfactorily holding it set in such

be wound and unwound easily.
Attention is now called to the numeral 25 in
Figure 4. This comprises a suitable receptacle,
guiding and tracking adapter for the pull chain

In the drawings the wooden shade roller is de
noted by the numeral 8 and this embodies a cen
tral axle or shaft 9 whose ends extend beyond
in 5 the corresponding ends of the roller proper and
anti-friction support or bearing for the trun
nion I0. Consequently, by supporting both ends

?ange 2i having down-turned guides 28 at oppo
site ends. These guides lead the chain-ends down
into desired parallelism for convenient reach and
operation. The numeral 29 designates an attach
ing flange, and this is secured to the inner side
of the bearing cup 23. ‘This adapter bracket 25
serves to accommodate the marginal tubed por~
tion of the escapement or ratchet wheel 30, this
being keyed on the trunnion l0 and interposed
between the bearing cup 23 and said adapter ?x
tures 25, as well as the adjacent end of the wooden
part of the roller 8.
Also attached to the bearing cup‘ is an L-shaped
member 3| carrying the spring trip or pawl 32.
The pawl is located for releasable ratcheting en
gagement with the teeth of the ratchet wheel 30.
Assuming that the device is set up and as
sembled as shown in the drawings, and referring
to Figure 2, it is evident that by pulling either
end of the chain 26, the links thereof being in
mesh or tracking connection with the teeth of
the gear wheel, said wheel is rotated and this in
turn rotates the shade roller, permitting winding
or unwinding of the shade depending on the di
rection of movement of the chain. The spring
pawl provides the desired ratcheting action and

also serves to retain the ratchet Wheel set when

It follows, therefore, that the gist of the in
the roller in either direction, a toothed Wheel con‘
vention is predicated upon a pair of companion
nected with one trunnion, a chain hanger con
supporting brackets attachable to the frame and
nected with one bracket and having a curved
?ange extending under the lower part of the
provided with roller bearing devices to accommo
date journals or trunnions on the opposite ends
of the shade roller. This is one feature. Sec
ondly, novelty is predicated upon the chain actu
ated ratchet wheel and pawl and ratchet features
cooperable with the chain. More speci?cally,
novelty is predicated on the individual ?xtures
I3, 20, and the accessories 25 and 3| and 32 seen
in Figure 4. Or stated otherwise, novelty is based
on the structural coordination of features in com
bination as well as the individual component
parts which mutually cooperate to render the
structure e?icient and reliable.
It is thought that the description taken in con
nection with the drawings will enable a clear un
derstanding of the invention to be had. There

While the preferred embodiment of the inven
tion has been shown and described, it is to be un
derstood that minor changes coming within the
?eld of invention claimed may be resorted to if
I claim:
1. In a structure of the class described, a pair
wheel, semi-tubular guides extending downardly
and outwardly at the ends of said ?ange and a 10
chain having an intermediate portion passing
over the ?ange and through the guides and said
portion of the chain engaging the teeth at that
part of the Wheel located in the hanger.
2. In a structure of the class described, a pair 15
of supporting brackets, a roller having trunnions
at its ends rotatably arranged in said brackets, a
toothed wheel on one trunnion, a chain hanger
connected with one bracket and having a down
wardly curved ?ange for receiving the lower part 20
of the wheel and downwardly and outwardly
curved guides at the ends of the ?ange, a chain
having an intermediate portion passing over the
?ange and through the guides with its links en
gaging the lower teeth of the wheel, a small 25
bracket supported from that bracket carrying the
hanger and a spring detent carried by the small
bracket and engaging the upper portion of the
toothed wheel to frictionally hold the same
against movement.
