Year: 1880

page_text: LETTERS PATENT to William Thomas Parr, of Kennington, in the County
of Surrey, for an Invention of "IMPROVEMENTS IN UMBRELLAS AND
PARASOLS."
PROVISIONAL SPECIFICATION left by the said William Thomas Parr at
the Office of the Commissioners of Patents on the 24th June 1880.
WILLIAM THOMAS PARR, of Kennington, in the County of Surrey.
MENTS IN UMBRELLAS AND PARASOLS."
"IMPROVE-
This Invention relates to improvements in the method of retaining and securing
an umbrella or parasol either open or closed, so as to dispense with the springs and
stops usually employed for this purpose in the sticks or handles.
In carrying out my improvements I form two slots, one from each end, in the
runner tubo with a partition between them. Upon the runner tube another tube
is mounted, retained thereon by a rim or projection on the runner tube or otherwise,
this outer tube being free to make a partial revolution.
Bayonet shaped slots are cut or formed in the outer tube, the vertical portions of
such slots corresponding with the slots in the runner tube.
•
Upon the stick or handle of the umbrella or parasol there are two studs, one to
retain the same when open, and the other when closed.
When the umbrella or parasol is opened the upper pin enters the vertical slots
in the combined runner tubes, and by a partial revolution of the outer tube the
fixed pin enters the horizontal portion of the bayonet slot in the outer tube, and
thus retains the umbrella or parasol open.
In like manner the stud near the handle enters the other bayonet slot in the
combined runner tubes, so as to retain the umbrella or parasol in position when
closed.

"IMPROVE-
This Invention relates to improvements in the method of retaining and securing
an umbrella, sunshade, or parasol either open or closed, so as to dispense with
the springs and stops usually employed for this purpose in the sticks or handles.
And in order that my Invention may be properly understood and readily carried
into practice, I will proceed to describe the Drawings hereto annexed, which show
several views of a runner tube a of an umbrella, sunshade, or parasol arranged
and combined with a locking tube b in accordance with my Invention.
Figure 1 shows separate views of the runner tube a, and Figure 2 shows separate
views of the locking tube b; Figure 3 shows the parts in the position ready for locking
when the runner a has been raised, and Figure 4 shows the position of the parts
when the locking tube b has been partly turned to place the fixed stud c in the
horizontal slot 62, so as to retain tho umbrella, sunshade, or parasol open.
Figures 5 and 6 show similar views of the parts when the umbrella, sunshade,
or parasol is closed, and held in that position by the fixed stud d.
In carrying out my improvements I form two slots a¹, a¹, one from each end, in
the runner tube a with a partition a² between them, as shown at Figure 1, which
is a separate view of the runner tube a.
Upon the runner tube a another tube bis mounted and retained thereon by a
rim or projection a³ on the runner tube a or otherwise, this outer locking tube b
being free to make a partial revolution.
Separate views of the locking tube b are shown at Figure 2.
Bayonet shaped slots b¹, b', are cut or formed in the outer or locking tube b, the
vertical portions of such slots corresponding with the slots a¹, a¹, formed in the
runner tube a.
Upon the stick or handles of the umbrella, sunshade, or parasol there are two
fixed studs c, d, one (c) to retain the umbrella or parasol when open, and tho other
(d) when closed.
When the umbrella, sunshade, or parasol is opened the upper pin c enters the
vertical slots in the combined runner tubes a, b, and by a partial revolution of the
outer tube b the pin c fixed on the stick s enters the horizontal portion b³ of
the bayonet slot in the outer tube b, and thus retains the umbrella, sunshade, or
parasol open.
Figure 3 shows the combined runner on the stick 8, the outer tube b being in
position ready to be turned to secure the umbrella, parasol, or sunshade in position
when open.
Figure 4 shows a similar view after the outer tube b has been partly turned
round, whereby the umbrella, parasol, or sunshade is then held securely open.
In like manner the stud d near the handle in closing the umbrella, parasol, or
sunshade enters the slot a¹, and the other bayonet slot b', b², in the combined
runner tubes a, b, so as to retain the umbrella, sunshado, or parasol in position
when closed.
Figures 5 and 6 show similar views to Figures 3 and 4, except that in these
views the umbrella, sunshade, or parasol is closed.
Figure 7 shows separate views of the locking tube b arranged with bayonet
slots 61, 62, which differ in form from those previously described, and whereby the
parts are rendered self opening and self closing.
Figure 8 shows the position of the parts when the umbrella, sunshade, or parasol
is retained open by the stud c and tube b, and Figure 9 shows the position of

page_text: the parts when the umbrella, sunshade, or parasol is closed and retained by the
stud d.
It will be seen that the slots in the locking tube b are formed with curves or
inclines, so that as the stud enters the slot b¹ it acts on the incline z, and causes
the tube b to partially rotate in one direction, and then by acting in its further
movement on the curved incline a' it causes the tube b to partially rotate in the
opposite direction, and thus cause the horizontal part 6 of the bayonet slot to
embrace the stud c (or d, as the case may be) to retain the umbrella, sunshade, or
parasol open or closed.
Figures 10, 11, and 12 show a combined runner a and locking tube b formed
with one bayonet shaped slot only to retain the umbrella, sunshade, or parasol
when open, other suitable means being employed to retain it when closed.
Having thus described the nature of my Invention, and the manner of performing
or carrying the same into practice, I would observe that I do not claim any of the
parts separately, which are well known and in common use, but what I claim
19,-
The improved arrangement, construction, and application of the locking tubo b
formed with bayonet slots b', b³, acting in combination with the runner tube a and
fixed studs c and d to retain the umbrella, sunshade, or parasol open or closed,
substantially in the manner herein before described and represented in the Drawings
hereto annexed.
In witness whereof, I, the said William Thomas Parr, have hereunto set my
hand and seal, this Twenty second day of December, in the year of our
Lord One thousand eight hundred and eighty.
