either strand D or D' first elevates the slide
and disengages the latch-levers from the stand-
ards, and a continued and quick pull elevates
the gate,and the momentum of the parts car-
5 ries the gate into the position shown by dotted
lines in Fig. 2. A quick pull upon either
strand when the gate is open suffices to close
it, and the gravity of the side cross-bar braces
and latch-levers is found sufficient to compel
io the engagement of the latch-levers with the
stops and hold the gate closed.
Having thus described my invention, what I
claim, and desire to secure by Letters Patent,
is-
15 1. The combination, with the gate having a
cross-bar, and mechanism, substantially as de-
scribed, for operating the cross-bar and mov-
ing it vertically, the weighted levers, and the
standards supporting the levers, of the latch-
20 levers pivoted between their ends to the
weighted levers and having their front ends
engaged by the cross-bar, and the stops for
engaging the rear ends of the latch-levers and
holding the gate closed, substantially as de-
25 scribed.
2. The combination, with the gate having
the cross-bar provided with openings near each
end, the slide and the braces, and devices, sub-
stantially as set forth, for pivotally supporting
30 it,whereby it is free to be thrown up out of the
way, of the latch -levers pivotally supported
between their ends and having their front ends
reduced and fitted in the openings in the
cross-bar, and the stops for engaging with the
latch-levers, substantially as and for the pur- 35
pose described.
3. The combination, with a frame having a
pulley, the posts located at a distance from
the frame and having overhanging arms pro-
vided with pulleys, the two oppositely-dis- 40
posed strands, the weighted levers, the stand-
ards supporting the levers, the gate having
the slide, and the cross-bar connected with the
slide, of the latch-levers pivoted upon the gate-
carrying levers and having their front ends 45
engaging with the cross-bar, and the stops pro-
jected from the standards and adapted to en-
gage the rear ends of the latch levers, sub-
stantially as described.
4. The combination, with the gate having 50
the slide, with hand-holds projected therefrom
centrally disposed between its ends, a verti-
cally- movable cross- bar, and connecting-
braces, of the latch-levers, the stops, and the
levers pivotally supporting the gate at each 55
end, substantiallyas described, and for the pur-
pose specified.
In testimony whereof I affix my signature in
presence of two witnesses.
