Improvements in retaining Mechanism for Sliding Rods for Fanlight
Openers and the like Purposes.
I, CHARLES PIIPSON SHOWELL, of the Firm of Edwin Showell and Sons, of Lower
Loveday Street, in the City of Birmingham, Brassfounder, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in mechanism for retaining sliding rods
or brackets, primarily for such as those used in fanlight opening mechanism, but
which may also be applied to sliding rods or other moving bodies for other pur-
poses such as blind cord brackets or racks.
According to this invention and as applied to the sliding rod of a fanlight opener,
a small box or frame is secured to the rod and usually at its end, which said box
carries two pivoted (thumb and finger) levers which are held apart by spring
action. In these two levers, and parallel to the rod a hole or gap is made through
which is passed a second and stationary rod, which is fixed at each end, and of a
length suited to the required travel of the sliding rod. The position and shape of
these levers is such that they angularwise kink or bind upon the stationary rod, so
that while in their normal position (under the action of the spring) the one lever
locks the sliding rod from movement in the one direction, and the other lever from
movement in the opposite direction. By pressing a lever or compressing the levers
together however, they are freed of the stationary rod and hence the sliding rod
may be raised or lowered at will by means of the one hand.
In means now in use having a similar gripping or locking device, the said
device has been stationary and therefore requires the one hand to unlock the levers
while the other hand was required to raise or lower the sliding rod.
In some cases such as in window blind brackets or racks, it is only required to
provide a locking or binding action in one direction of movement, consequently
in such cases one lever only is used, when I may further attach a spring to the
moving bracket (at the rear) which shall sufficiently bind it to the fixed rod to
prevent its accidentally falling off (in the unlockable direction). To this bracket
is attached the usual cord pulley.

Improvements in retaining Mechanism for Sliding Rods for Fanlight
Openers and the like Purposes.
I, CHARLES PIPSON SHOWELL, of the Firm of Edwin Showell and Sons, of Lower
Loveday Street, in the City of Birmingham, Brassfounder, 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 :-
This invention relates to improvements in mechanism for retaining sliding
rods or brackets, primarily for such as those used in fanlight opening mechanism,
but which may also be applied to sliding rods or other moving bodies for other
purposes such as blind cord racks or door bolts.
In order to more clearly explain this my invention I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part.
Fig. 1, is a general side view of the invention as applied to a fanlight opening
and closing mechanism.
Fig. 2, is an enlarged side view in part section of the invention.
Fig. 3, is a sectional plan view on line A-B Fig. 2.
Fig. 4, is a detached detailed view of one of the grip levers.
Fig. 5, is a modified view of the invention showing its application to a blind
cord bracket or other similar purpose.
Referring to Figs. 1, 2, 3 and 4, and as applied to the sliding rod of a fanlight
opener, a small box or frame 7, is secured to the moving rod S, and usually at its
end, which said box carries two pivoted (thumb and finger) levers 9 and 10, which
are held apart by spring 11. In these two levers, and parallel to the rod 8, a
hole or gap 12, is made through which is passed a second and stationary rod 13,
which is fixed at each end to brackets 14 and of a length suited to the required
travel of the sliding rod S. The position and shape of these levers 9 and 10, is:
such that they angularwise kink or bind upon the stationary rod in their holes 12,
as seen in Fig. 2, so that while in their normal position (under the action of the
spring) the one lever 9, locks the sliding rod S, from movement in the upward
direction, the other lever 10 similarly locks it from movement in the downward
direction. By compressing the levers together however, or by simply downwardly a
pressing the upper lever, and lifting the lower lever, they are freed of the
stationary rod 13, when the sliding rod may be raised or lowered at will by means
of the same (one) hand.
In means now in use having a similar gripping or locking device, the said device
comprising the box 7, and levers 9 and 10 &c. has been stationary, and therefore 3
required the one hand to unlock the levers while the other hand was required to
raise or lower the sliding rod.
In some cases such as in window blind racks it is only required to provide a
locking or binding action in one direction of movement as shown in Fig. 5, in
which 15, is the blind cord carried over pulley 16, carried upon the lever bracket 9 4
In order to prevent the accidental dropping of the bracket 7", when the cord 15,
is removed I place a spring 11", which serves not only to prevent the said
dropping but also tends to keep the grip hole 12 binding upon the rod 13. It will
be readily seen that the rod S, may constitute a sliding bolt or the like under
similar operation.

page_text: Having now particularly described and ascertained the nature of this my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is
1. The combination of a fixed rod 13, a sliding box 7 having gripping levers 9
and 10, spring 11, such box being attached to sliding rod 8, all substantially as
set forth and shown in Figs. 1 to 4 inclusive.
2. The modified combination of a fixed rod 13, a sliding gripping lever
bracket, spring 11", and cord pulley 16, all substantially as set forth and
shown in Fig. 5.
Dated this 28th day of February 1899.
