The present invention relates to actuators for
hinged closures. Swinging closures, such as
French windowshatchway covers, screens, ven
tilator lifts, and like structures usually have
5 actuators for manipulating them so that the clo
sures may be readily and easily moved to ad
justed position.
It has been found from experience that some
times French windows and like closures are so
heavy that they become warped, whereupon it is
impossible to eifect closing tightly enough to exelude rain, snow, sleet and the like. Actuators
for such closures are‘ used at the present time,
but none is capable of ready adjustment to effect

" lowing description and accompanying drawings.
The accompanying drawings illustrate embodi

Figure 7 is a View, partially in horizontal section
or closure member B is illustrated as a window
carrying a pane or glass C‘, with top and bottom
sash rails 2 and 3 respectively, vconnected at their
ends to stiles 4 and 5.
The actuator illustrated in Figures 1, 2, 3, 5 and
6 includes a stamped plate 6 havinga horizontal
?ange l for attachment to the sill of the frame
and a vertical ?ange 8 attachable to the upright
member of the frame, by screws or other suit
able attaching means. Between the horizontal
portion of the plate 6 and the vertical ?ange 8,
and between the side margins of the plate, it is
cut away forming an opening 9, in which is rotat
ably mounted a worm Ill. The worm I0 is keyed 35
or otherwise fastened to a sleeve II which is of
greater length than the worm, projecting from
both ends of the worm, as may be observed in
Figure 6.
A supplemental plate I2 is fashioned with ears gs 0
which are bent around the extending end por
tions of the sleeve II to- secure the sleeve and
worm in position in the plate 6. These portions
which are bent around the extremities of the
sleeve ll form bearings l3 for the sleeve and
worm. Between. the horizontal portion of the
plate 6 and the vertical flange 8, the plate is
curved downwardly at I4, as shown in Figure 1,
to receive portions of the bearings I3 for the
sleeve II. The worm Ill is thus supported in
the plate with its axis in horizontal position and
closely adjacent the portion. of the frame A to
which the vertical ?ange 8 of the plate is at
The horizontal portion of the plate 6 is aper
the frame A in parallel relationship to the hinge
integral portions of the crank which are laterally
spaced from the side margins of the lever 31.
The lever 31' is provided with upstanding ears 44
and 45 which constitute stops. Threaded into
connections of the sash or closure member Bv to
the ears 42 and 43 are screws or bolts 46 and 4-1,
the frame A.
which may be adjusted towards and away from
the cars 44 and 45 of the lever to position the
lever in desired angular relationship with respect
to the crank 36, and also to afford driving con
nection between the crank and the lever.
The sleeve H which drives the worm II] is
fashioned with a polygonal interior Ha (Figure
6) to receive the correspondingly shaped end of
a removable crank 49. Preferably, the polygonal
interior i Id of the sleeve is disposed at the inner 15
end of the sleeve in spaced relationship to the
tured at “5, the supplemental plate l2 being aper
tured to register therewith, for receiving the lower
end of a vertical shaft 25 which is supported in
A stamped gear I‘! having teeth
i8 for meshing with the worm I0 is pivoted on
the shaft i5. The gear I? is incomplete as far
as its peripheral portion is concerned, and has
143' a tail'extension 18a.
A lever 19 is apertured to surround the shaft
I5 and rest on top of a portion of the gear I‘!
and its tail portion laa. The lever I9 is opera
tively connected to the tail portion l8? of the
gear by means of a screw 20 passing through an
aperture in the lever and threaded into the tail
18%, ,thus connecting together the gear and the . entrance end thereof, to prevent ready insertion
lever for oscillating with the shaft. In order to of a tool for operating the actuator of the pres~
oscillate the shaft l5 in accordance with oscilla- ' ent invention to manipulate the sash from its
tory movement imparted to the lever_.l9, any
suitable driving connection may be employed.
I The driving connection illustrated consists of
two diametrically disposed slots 2| and 22 formed
in the leveradjacent the shaft i5, and the shaft
i5 is apertured to receive a pin 23 which lies in
the slots 2| and 22. The pin 23, in addition to
connecting the shaft l5 and lever l 9 together for
oscillatory movement, supports the shaft in ver
tical position with respect to the bracket 6. The
upper end of the shaft I5 is supported by a
stamped bearing including an attaching plate
portion 24 and a barrel 25 which receive the upper
end of the shaft. For a distance extending down
wardly fromthe upper end of the shaft, the shaft
is recessed at 26, to thereby provide a ?at sur
face 21.,
Attached to the lower rail 3 of the sash B,
is an elongated stamped metal ?anged member
28 arranged with its ?ange 29 parallel to and
11'. spacedfrom the raii 3. This member 28 is se
cured to the lower rail of. the sash by means of
screws 30 or other suitable fastening means.
Pivoted to the free end of the lever i9 is a shoe
3| having a J-shaped formation to engage the
opposite faces of the ?ange 29 of the member 28
and pass underneath the margin of the ?ange,
as readily observed in Figure 10. The shoe 3|
is pivoted to the free end of the lever I9 by
means of a pin 32, so that play may occur be
respect to the frame by inserting the crank 49
in the sleeve H, with the polygonal-shaped end
of the crank engaging the interior Ila of the
sleeve, whereupon rotation of the crank 49 in 25
clockwise direction, as viewed in Figure 1, will
cause the sash B to be swung to opened position,
that is, with its free margin swung upwardly, as
viewed in Figures and 3. When the sash has
been moved to desired position, the crank may be 30
withdrawn, whereupon the sash remains in this
position until the crank is again applied and
the worm rotated to move the gear I‘! in such
direction as will move the sash to another ad
justed position.
It sometimes happens’ that hinged closures,‘
such as screens, French windows, screen doors
and the like, which are manipulated by actuators,
warp or sag, which warping is especially notice
able at the upper outer corner of the closure.
When such warping occurs, it is well nigh impos
sible to secure tight sealing between the closure
and its frame. The provision of. the adjustment
betweenthe upper lever 3‘! and the crank 36
takes care of such warping.
Assume that the upper outer corner of the
sash B of Figure 1 had warped outwardly so
that manipulation of the levers l9 and 31 would
not. effect tight sealing of the closure against its
tweenthe shoe and the lever when the shoe is
moved back and forth along the ?ange 29 to
swing the sash or closure member B to adjusted
upper outer end of the sash tightly against its
frame, and thus overcome the effect of the
warped condition of the sash.
The amount of adjustment of the lever 31 with
Attached to the upper rail of the sash B is a
similar member 33 having a ?ange 34 extending
along and in spaced relation to the rail, as may
be observed in Figure 9. This member 33 is
secured by screws or like fastening means 35.
Keyed or otherwise ?xedly secured to the upper
60 end of the shaft, a slight distance below the
barrel 25 of the bearing member, is a crank 38
which projects along the upper rail of the sash
for a short distance. An upper lever 31 is aper
tured at one end as at 38 to surround the shaft
85 and to have movement relatively to the shaft.
1 The lever 37 carries at its free end a shoe 39,
pivoted thereto by a pin 49. The shoe 39 has a
hooded part 4! which engages over the upper
margin of the ?ange 34 of the member 33 and
bears against opposite sides of the ?ange, as the
shoe is moved in use. Means are employed for
connecting the crank 36 to the lever 31 in driving
adjusted position, by an unauthorized person.
The sash B is moved to adjusted position with
The means illustrated for accomplishing this
purpose comprise upstandinglugs Hand 43 as
In this event, the screws or bolts 46 and r
41 are manipulated as to so angularly adjust the
lever with respect to the crank as to draw the
respect to the crank 36 depends, of course, on the
warped condition of the closure, which such ad
justment is intended to overcome.
The lever 31
and crank 36, in Figure 2, appear with the parts
in normal position. If the closure member B is
slightly warped, then the screw bolts 43 and 41
would be adjusted to move the left hand end of
the lever, as viewed in this ?gure, a slight dis=
tance below that shown in the ?gure, so that
when the closure member is moved against the
frame, added pull will be exerted by the shoe
which engages the ?ange 34 of the member 33.
Figures 7 and 8 illustrate a modi?cation
wherein the upper lever 31 and the upper member 70
33 are eliminated, and instead of the utilization
of theshaft l5, a pivot pin is employed. In this
form of the invention, a stamped metal plate 48
is provided with spaced ?anges 49 and 50 for
attachment to the sill 5| of a closure frame.
The central portion of the plate 48 lies above the
?anges 49? and 50. The central portion of the
plate 48 is apertured at 52 to receive a pivot pin
53*, which pin has a head,54,,a cylindrical portion
55' to closely ?t within- the aperture 52, and an
other cylindrical portion 56 of reduced diameter.
This portion‘ of reduced diameter is counterbored‘
and threaded to receive a screw 51'.
Surrounding the portion 56' of the pin- is a gear
formed of. two- similar stamped sections 58! and
The sections 58 and 58' are separately
stamped‘ and then are brought together with
their teeth in register and so held, and then cen
trally bored to form the center opening for the
15 pivot. A horizontally disposed worm 59 is keyed
or otherwise secured to a hollow sleeve 60, the
ends of which are supported in apertured lugs
6! and 62 turned up from the material of which
the plate 48 is made. The worm 59 is in mesh
with the gear composed of the sections 58 and 58’
and designated generally at E.
A lever 63 of stamped ?at metal is apertured
to surround the pivot pin 53, surrounding the
portion of reduced diameter 56 of the pin. The
25 lever 63 is secured to the gear D by means of
rivets, bolts or like attaching means 64 which
pass through the lever and sections 58 and 58’,
thus connecting the gear and lever together for
cooperative action.
For covering the worm 59 and sleeve 60, a cover
plate of stamped metal 65 has a part overlying
the gear D, a part overlying the worm, and a
horizontal ?ange 66 which rests on top of the
?ange 58 of the plate 48. The cover plate is
35 held in position by screws 61 passing through
it and the ?ange 56 of the plate 48 and entered
in the sill 5| of the frame. The screw 51 passes
through an aperture in the cover plate and is
threaded into the pin 53. The hollow sleeve 60
40 which carries the worm 59 is provided with a
polygonal portion 60' to receive the similarly
shaped end of a crank, such as the crank 49, for
rotating the worm to actuate the lever 63.
This form of the invention is utilized in con
45 nection with a hinged closure, where but one
lever is su?icient to- operate the closure.
In Figures 4 and 11, there is illustrated an
exempli?cation of the application of an actuator
of the present invention to the lift of a trailer
50 ventilator. As usually constructed, trailers are
provided with ventilators in their roofs which,
when opened, permit circulation of air from the
interior of the trailer to the outside. The problem of closing such ventilators, as regards
55 weather conditions, is important.
It is neces
sary to effectively seal such ventilator openings
to prevent entry of rain, snow and wind to the
interior of the trailer.
In this form of the invention, 68 represents
60 a wall built around the ventilator opening in the
roof of a trailer. Hinged at 68 to the wall is a
lid or hinged closure 16 adapted to be moved on
in a direction away from the worm.
about the pivot 80 is a lever 83 which is con
nected to the tail 82 of the gear by means of a
rivet 84, thus connecting the lever and ‘gear in
operative relationship. Carried at the free end of
the lever 83 is a shoe 84 having a part engag
ing opposite surfaces of the ?ange 12 of the mem
ber TI‘. The shoe 84 is pivoted to the lever 83
by a suitable pin 85 so that relative rocking
movement may occur between the lever and the
shoe, as the closure member 18 is moved about
its’ hinged connection to the wall 68.
For manipulating the closure member or lid
"ill, the shaft 18 is provided with a hand wheel
86 disposed near the roof of the trailer and which 15
may be readily manipulated from the interior
of the trailer.
To open the lid or closure mem
ber 70, the hand wheel 86 is turned to the right,
whereupon the free end of the lever 83 rises and
opens the lid 10 about its hinges. To close, the 20
hand wheel is rotated in the opposite direction,
the shoe 84 cooperating with the frame 12 to
close the lid against the wall 68.
By reason of the construction illustrated and
described, the lid or closure may be tightened 25
against the wall 68 in sealing relation, by giving
the hand wheel 86 an additional turn to the left
after the closure has been seated, whereupon a
squeezing effect takes place between the closure
and the wall. If desired, suitable gasket means
might be secured to the margin of the wall for
engagement by the lid when it is in closed posi
tion, as an added means for preventing ingress
of rain, snow and sleet.
It will be observed that the actuator of the =
present invention is one which, in the main,
may be manufactured by stampings, as all of the
parts, except the worm, the crank and the worm
mounting sleeve, may be stamped from suitable
metal, thus reducing the cost of manufacture of
the actuator. The manner of assembly is simple
and can be carried out at minimum expense for
The actuator herein described has proved very
eflicient in use, and as made is rugged and sturdy 45
to withstand all abuse to which such a device may
be put in service. The provision of two levers
applied to the top and bottom rails of a large
and heavy closure is an advantage because of the
fact that the upper lever may be so adjusted as 50
to effect tight sealing of the closure against the
frame, should the closure be warped.
The invention has been described herein more
or less precisely as to details, yet it is to be under
stood that the invention is not to be limited 55
thereby, as changes may be made in the arrange
ment and proportion of parts, and equivalents
may be substituted, without departing from the
spirit and scope of the invention.
