OPERATING DEVICE FOR CLOSURES
Martin S. Kirkpatrick, Elmendorf, Tex.
Application March 9, 1937, Serial No. 129,890 i
5 Claims.
This invention relates to operating devices for
closures such as gates, doors and the like of
the lsliding type and has vfor the .primary object
the provision of an efficient and inexpensive de
5` vice of this character which may be easily ac
tuated by a person to slide the closure either to
open or closed positions Without the person mov
ing from a selected position of operation and
includes means for checking the movement of
10 the closure as it nears either its open or closed
position to prevent said closure from stopping
suddenly which might damage the closure or the
parts of the operating device.
.
With these and other objects in view, this in
vention consists in certain novel features of con
struction, combination and arrangement of parts
to be hereinafter more fully described and
claimed.
For a complete understanding of my invention,
20 reference is to be had to the following descrip
tion and accompanying drawings, in which
Figure 1 is a side elevation, partly in section,
illustrating a closure equipped with an operat
ing device constructed in accordance with my
25 invention.
Figure 2 is a fragmentary side elevation, partly
in section, showing parts of the operating de
vice occupying positions when the closure is in
30
an open position.
Figure 3 is a sectional view taken on the line
3-3 of Figure 2.
_
Figure 4 is a sectional view taken on the line
3
40
4-4 of Figure 1.
Figure 5 is a fragmentary sectional view illus
trating a pulley construction.
Figure 6 is a detail sectional View taken on the
line 6_6 of Figure 1.
I have elected to show my invention adapted
to a sliding type gate I, however, the present
invention is readily adaptable to other types of
closures.
Shown associated with the gate are
vertically arranged posts 2 and 3 forming there
between an entrance to be closed by the gate I
and to be opened by the gate I moving in the di
4
rection of a post 4 located beyond the post 2.
The posts are connected by a cross member 5,
the height of which is such that vehicles and the
like may pass freely through the entrance be
tween the posts 2 and 3. A track 6 is connected
to the posts in a plane below the cross member 5,
however, at a height which will be sufficient to
permit passing of vehicles and the like through
the entrance defined by the posts 2 and 3. Hang
ers 'I secured to the gate I are provided with
rollers
8 that travel on the track 6 so that the
55
(Cl. 353-25)
gate may be made to slide freely to open and
closed positions. The track 6 is of channel iron
construction which will aid in excluding weather
elements from the rollers 8. The upper portions
of the posts are slotted and operating therein
is a beam 9, one end of which is pivoted to the
post 4, as shown at I0, while the opposite end
projects slightly beyond the post 3 and has
pivoted thereto a hanger or bracket II on which
are journaled connected sheaves I2 and I3. The
last-named end of the beam is connected to an
operating lever I4 by a connecting rod I5. The
operating lever I4 is pivoted on the post 3 ad
jacent the vground and its free end is pivotally
connected to a pivotally mounted treadle I6 lo
cated adjacent the entrance deñned by the posts
2 and 3.
A groove I1 is formed in the beam 9 and ex
tends substantially the full length thereof to pro
vide a guideway for one run of a cable I8. .-Ar1-'
other run of the cable passes over a pulley I9
journaled on the post 4 and a pulley 20 jour
naled on the pivoted end of the beam. One end
of the cable is fastened to one end of the gate,
as shown at 2l. The cable as it leaves the guide
way at the non-pivoted end of the beam passes
over a pulley 22 journaled on the beam and also
passes about the sheave I2 and is connected to
the opposite end. of the gate by a member 23.
A flexible element 24 is secured to one end of
the member 5 and to a bracket 25 secured on
the post 3. The flexible element 24 is disposed
vertically and is> passed about the sheave I3 so
that said sheave will be rotated by the upward
and downward movement of the free end of the
beam 9. The sheaves being thus rotated will
cause the gate to be slid open and closed. AS
the free end of the beam moves upwardly, the
gate slides open and as the free end of the beam
moves downwardly the gate slides closed. The
pivotal movement of the beam 9 is caused by
the manual actuation of the treadle I6.
A supporting structure 26 is secured to the post
3 and includes horizontally and vertically ar
ranged members and secured to the horizontal
member are pulleys 2l over which a flexible ele
ment 28 is trained. Pivoted on the supporting
structure 26 are levers 29 and 3U located in the
path of movement of the operating lever I4 and
arranged above and below the latter. One end
of the flexible element 28 is secured to the lever
3U and the other end of the flexible element has
a weight 3| secured thereto. The flexible ele
ment 28 is secured to the lever 29. As the oper
ating lever I4 moves upwardly to bring about 55
2,125,183
opening of the closure it engages the lever 29
lifting the weight 3i for the purpose of checking
or retarding the movement of the closure to
wards said open position and on movement of
the lever Iâ downwardly to close the gate it en
gages with the lever 30 bringing about raising of
the Weight 3| and thereby checking or retarding
the movement of the closure towards a closed
position. It is to be understood that the oper
10 ating lever I4 only engages the levers 29 and
30 as the closure nears its closed or open position,
What is claimed is:
'
to engage the sheaves for imparting rotation
thereto by the pivotal movement of the beam,
operating means connected to the beam for im
parting pivotal movement thereto, flexible means
connected with opposite ends> of the closure and
engaged by the sheaves for sliding the closure
by the pivotal movement of said beam, means for
slidably mounting the flexible means on the Y
beam, and means connected tovsaid operating
means for retarding the movement of the clo 10
sure'as the latter, reaches near the limit of its
movement.
