Year: 1899

page_text: I, JAMES HUGHES, of 29, Rosemary Lane, Beaumaris, Anglesey, Joiner, do
hereby declare the nature of this invention to be as follows:-
This invention refers to the mechanism for raising and lowering window
blinds of the usual cloth type.
It consists in modifying the usual wheel end of the metal fittings, by cutting
ratchet teeth on same, and in forming a hinged curved detent with a tooth
forming a dog, to hang in front of and engage with same.
This curved detent when allowed to drop by gravity stops the action of the
roller. A slot is made in its lower end through which the cord passes, and when
this cord is pulled outwards away from the window, it lifts the detent off the
ratchet and so frees the roller. The detent is hung on a suitable part of the
bracket which is extended for the purpose.

I, JAMES HUGHES, of 29, Rosemary Lane, Beaumaris, Anglesey, Joiner, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and By the following
statement:-

when allowed to drop by gravity, stops the action of the roller. A slot is made
in its lower end through which the cord passes, and when this cord is pulled out-
wards away from the window, it lifts the detent off the ratchet and so frees the
roller. The detent is hung on a suitable part of the bracket which is extended
for the purpose.
I will now describe my invention with reference to the accompanying draw-
ings in which,
Fig. 1 shows an elevation of a window blind roller with my improved fitting
attached.

page_text: Fig. 2 shows a sectional end view on line z-2.
a is the window blind wound on roller b. The latter is supported in the
usual way by end spindles c in bearings c¹. One of the spindles c is fitted with
a ratchet wheel d, the teeth of which engage with the tooth e of a curved
detente pivotted at e to one of the bearings c¹. The blind cord f passes
through an opening in the lower end of the detent e', and is fastened to the
spindle c.
The tooth on the detent normally engages the ratchet wheel teeth by gravity,
and on pulling the blind cord away from the window, the ratchet will be freed
and the blind will unwind and fall by gravitation while the cord will be wound
up on the spindle, so that the blind can be wound again around the roller when
desired, by pulling the cord.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. An improved blind-roller fitting, worked by a single cord and consisting
of an ordinary metal wheel roller end, to which a ratchet is added, said ratchet
being controlled by a curved detent furnished with a dog or tooth which engages
with said ratchet, said detent being operated by the cord, as herein described
and set forth.
