Conventional fencing constructions are generally sup-.

Referring particularly to FIGS. 4~6, one of the posts
10 is utilized as a mounting sleeve for a rod 25 which is
freely received in the post, and is maintained in position
therein by the long mounting studs 27, which are threaded
or otherwise suitably fastened into the rod 25 above and
below the ends of the post 10.
The rod and the two ‘
studs thus form a generally U-shaped mounting member
which can rotate about the vertical axis of the post 10,
within the limits formed by the struts when they are in
position. The studs 27 provide a slide mounting for
upper and lower sleeves 30 which are free to slide along
the studs '27, and which are fastened to further sleeves
32 (FIG. 6) extending at right angles to the sleeves 30.
A capstan shaft 35 extends through the sleeves 32, and
the shaft is undercut as shown at 36 adjacent its upper 15
and lower edges to ?t around the inwardly extending part
of the horizontal sleeves 30, thus forming an interlocking
construction which maintains the parts in assembled re
lationship.
4
FIGS. 7 and 8 show an alternate capstan construction
which is usable particularly where it is for some reason
undesirable to mount the capstan on a corner post.
In
this modi?ed construction a pair of sleeves 60 are pro
vided which ?t over the struts 18 of the framework. Each
of these sleeves has an L-shaped arm 62 fastened thereto,
and these arms in turn provide support for the sliding cap
stan sleeves 30a, which together with the remainder of
the capstan construction may be exactly the same as that
previously described. Therefore, the same reference nu
merals have been applied to these parts in FIGS. 7 and 8.
As the fencing fabric is rolled onto the capstan tube 38,
the sleeves 30a will slide outwardly 0n the arms 62 to
accommodate the increase in size of the roll.
In some instances it may be desirable to incorporate a
gate ‘construction in the collapsible portable fencing pro
vided by this invention. A suitable arrangement for this
purpose is shown in FIGS. 9 and 10. The gate construc
tion is provided here as a substitute for one of the corner

ing position, resting against the stop ‘52, the sleeve 50
extends across the meeting faces of the parts 42 and 45,
and locks the two together preventing rotation of shaft
35.
The fabric strip 20 can be engaged with the pins 40 on
the capstan merely by hooking these pins through the
fabric, and the fabric can then be placed about the ex
terior of the framework and brought back around the
corner posts in which the capstan is mounted such that
the other end of the fabric also may be engaged with
the pins 40. This arrangement is shown in FIG. 5, and
it will be understood that with such a construction there
is no access through the sides of the fencing, but the 55
interior of the enclosure may be reached by climbing over
a side of the structure.
A suitable wrench or lever arm is then applied to the
sleeve 50, with the sleeve in its raised position (dotted
lines in FIG 6) and the capstan can be rotated to draw
the fabric taut about the framework. The sleeve 50 is
then dropped to engage also with the polygonal end 42
on the upper sleeve 32, and the capstan is locked to main
tain the tension in the fencing fabric. When it is de
sired to disassemble the structure, the sleeve 50 can be .65
released to relieve the tension, then one end of the fabric
strip is unhooked from the capstan, and the same is
rotated to wind the fabric into a roll about the capstan
tube. At this time, the sleeves 30 will slide toward the
outer end of the studs 27 as the roll of fabric increases
70
in diameter. Once all the fabric is rolled up on the cap
stan the framework can be easily disassembled, and the
capstan provides a convenient carrier for the roll of
fabric, being retained on the corner post 10 to which it
is assembled.
75
Obviously, the fencing construction shown in FIGS. 9
and 10 may likewise be disassembled readily and the gate
frame itself disassembled into pieces, with only the gate
75 remaining connected at its hinges 77 to the one gate
frame side piece 65 if so desired.
While the forms of apparatus herein described con
stitute preferred embodiments of the invention, it is to
be understood that the invention is not limited to these
precise forms of apparatus, and that changes may be
made therein without departing from the scope of the
invention which is de?ned in the appended claims.
