MARY ELEANOR ROOKE, Brassfounder 13, Bath St. Birmingham, GEORGE Price,
Mechanic, 13 Bath St. Birmingham do hereby declare the nature of this invention
to be as follows:-
The part of the Rack pulley for which we claim protection is a jointed or hinged
catch or movement of sheet brass or cast brass, or other metal as the case may be,
which may
be bent at the edges for the carrier to move either up or down smoothly
in or on the ratchet part of the rack. It is jointed near the centre of the move-
ment so as to raise it or lower it on the ratchet part of the rack. There is a spring.
attached to the movement which presses that part of the same into the ratchet.
We may make it without being jointed, which alteration is made by the metallic
catch and spring being made in one piece, the object being to produce a cheap
simple and effective article.

page_text: We, SAMUEL JOHN JONES ROOKE, MARY ELEANOR ROOKE Brassfounders and
GEORGE PRICE Mechanic all of 13 Bath Street Birmingham in the County of
Warwick 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 :—
The object of our invention is improvements in blind racks which renders them
very easy and simple in their action and yet most secure Much complication
exists in some of the racks now in use and they easily get out of order and our
invention is intended to meet the want of both in regard to simplicity and
effectiveness.
In order that our invention may be the better understood and more easily
carried into practice we have appended hereunto a sheet of drawings upon which
we have illustrated several examples thereof.
Figure 1 is a front elevation of one of our window racks with the cord guard
plate A Figure 3 removed.
Figure 2 is a vertical section on the line B. C.
Figure 4 is a cross section on the line D. E.
Figure 5 is a part vertical section of the cord pulley and saddle of a modified
form as will be hereafter explained.
Figure 6 is a front view of Figure 5 but with the knob and pulley K removed.
Figure 7 is a front view of Figure 5 with the knob and pulley K in its position.
Figure 8 is a front view of a different kind of rack frame but with our spring
saddle adapted thereto.
•
Figure is a vertical section on line F. G of Figure 8.
Figure 10 is a front view of the internal spring saddle H with the cord guard
plate A removed and Figure 11 is a cross section of the said saddle.
On referring to the drawings Figure 12 will be seen to be a plate cut or stamped
out so as to form the saddle M when the parts m³ and m³ are bent around to
enclose the edge of the plate P while the point m³ is so bent as to enter the holes pl
in the rack plate P while the horns m' and m³ serve when turned round as guards
to limit the bend of the spring saddle when the point m³ is drawn out of the
hole p¹. Looking for a moment at the section Figure 2 it will be seen that by
pressing the top of the guard plate A to the left the point m³ of the spring saddle
will be lifted out of the holes p¹ in the rack plate and the horns m' will rest against
the under side of the plate and the saddle will thus be free to move any distance in
*either direction without any hindrance whatever whereas immediately the pressure
upon the plate is released the point m³ will again take into any hole p¹ nearest to
it and so again secure the saddle.
In Figure 5, 6, and 7 the only difference in the saddle is that the saddle plate M
is made in two parts and hinged together at me the spring being given to keep the
point m³ in position by the separate spring m' secured to the bottom of the saddle
by the rivet me otherwise the action just the same and the working easy and
regular Of course in the former examples Figures 1, 2, 34, and 12 the saddle
plate is also by its peculiar shape a spring in itself.

page_text: The rack shown by Figures 8, 9, 10, and 11 differ simple by the adaptation of
the saddle to a different rack plate R in which there are no holes p¹ the saddle
point holds againts projections ¹ pressed up out of the back of the plate we
make no claim to either of the rack plates. The saddle H in this case is made from
a plate H shown at Figure 13 the point ¹ being bent to take into the notches
and the projects h and h³ are bent to form a sliding surface as shown at Figures 10
and 11 which makes the action smooth when the point h¹ is lifted out of the
notch by A as previously explained in regard to Figure 2 there being sufficient
length in the neck 8 to allow the necessary movement This saddle H as well as M
is free to move in either direction when the point h¹ is lifted out.
Having therefor now described and ascertained the nature of the said invention
and in what manner the same is to be performed what we claim is :—
The improvements in blind racks having a spring saddle M or H formed either
from one piece of metal or with a joint me substantially as and for the purpose
herein set forth.
