(Cl. 155——63)
This invention relates to glider swings.
The primary feature of the present invention
is to construct a swing that maybe operated by
the occupants of the swing thereby eliminating
1.5 the necessity of children being pushed or pro
pelled by others when they are playing.
Further objects of the invention are to provide
a swing of the character referred to that is strong,
compact and durable, affording much entertain
ment and wholesome exercise for the children.
and that is comparatively inexpensive to manu
facture.
-
With the foregoing and other objects in view
the invention consists of a novel construction,
combination and arrangement of parts as will
be hereinafter more speci?cally described and
illustrated
in
the
accompanying
drawings
wherein is disclosed an embodiment of ‘the in
vention, but it is to be understood that changes,
20 variations, and modi?cations may be resorted to
without departing from the spirit of the claims
hereunto appended.
In the drawings wherein like reference char
acters denoted corresponding parts throughout
the several views:
‘
Figure 1 is a. detailed vertical section through
the swing constructed in accordance with the
present invention.
Figure 2 is an enlarged detailed section taken
30 substantially on line 2—2 of Figure 1.
Figure 3 is a fragmentary horizontal section
taken through the upright members of the frame
above the seat board.
Figure 4 is a fragmentary top plan view of a
35 portion of the top of the supporting member.
Referring to the drawings in detail, A indicates
generally the frame from which the glider swing
of the present invention is suspended. This
frame consists of a horizontal base 5 adapted to
Rising from each side of the
base 5 and from the middle thereof are a pair
of standards 6. Each of the side standards 6 are
40 rest on the ground.
braced with a pair of diagonal props l, 8.
The
lower ends of these props are secured to the ends
45 of the base, while their upper ends are secured to
the standards 6. Bridging the space between the
standards 6 is a cross brace 9 the opposite ends
of which are securedrespectively to the upper
ends of the pair of standards 6. To the center
50 of the cross brace 9 is nailed or otherwise secured
as at H) the center of a cross bar I I.
This cross
bar H extends at right angles to the cross brace
9 and is located in a plane between the side
standards 6.
The upper ends of a pair of spaced cables I2,
55
l3 are secured in the eye bolts l4, I5 respectively,
which bolts are anchored to the ends of the cross
bar H. The plane of these cables l2, I3 is at
right angles to the suspending cables as will here
after appear.
The swing frame indicated generally at B in
the form of the invention illustrated is made of
pipe, but it is within the contemplation of the
invention to use other steel shapes or wood in
constructing the frame. At rest, the frame B is 10
suspended in a vertical plane and all members
thereof are disposed in the same plane. The
frame B is made of a top rail l6 and. a bottom
rail ll disposed in parallel relation. A pair of
vertical upright members l8, l9 are disposed be 15
tween the top and bottom rails inwardly of the
ends thereof.
The opposite ends of upright member I8 is rig
idly connected with the top and bottom rails by
the T-shaped ?ttings 20.
The opposite ends of '20
upright member I9 is likewise connected with the
top and bottom rails by like ?ttings 2 I.
Bridging the space between the uprights l8, I9
is the fulcrum bar 22 and the ends of this ful
crum bar are connected to the centers of the ' 25
upright members I8, l9 by the T-shaped ?ttings
23. It will be seen that top and bottom rails,
18, ll and upright members i8, l9 and the ful
crum bar 22 all lie in the same vertical plane
30
when the swing is at rest.
The center of the seat board 24 rocks upon the
fulcrum bar 22 so that the opposite ends thereof
project on the opposite sides of the frame B.
For the purpose of rockably mounting the seat
board 24 on the fulcrum bar 22 there is provided
a U-shaped bearing plate the depending crown
25 thereof embracing fulcrum bar 22. The mar
gins of the legs 29 of the bearing plate are nailed
as at 27 to the lower face of seat board 24.
On the free opposite ends of the bottom rail 40
ll are secured the T-shaped ?ttings forming the
sleeves 28. The free ends of the top rail I9 are
likewise equipped with T-shaped ?ttings provid
ing sleeves 29.
The sleeve 28, 29 on one side are
in alignment with each other while the sleeves 45
28, 29 on the other side are also in alignment.
For suspending the swing frame B, it is pre
ferred to use a single length of cable C. The
ends of the single length of cable C are secured
to the spaced eye bolts 30 anchored in spaced
relation to the top cross brace 9 of the support
A. This single length of cable C when suspend
ing the swing frame B is formed into the vertical,
lateral suspending members 3|, 32. suspending
member 3| is trained through the sleeves 29, 28 55
2,129,140
on the one side while suspending member 32 is
trained through the sleeves 29, 28 on the other
side of the frame. 'The single length of cable
C then is extended across the bottom of frame B
forming a horizontal length 33 which is below
and parallel to the bottom rail I ‘I.
On each projecting end of the seat board 24
is an opening 34‘ and through these openings in
termediate portions of cables I2, I3 extend. The
10 ends of cables I2, I3 project below the seat board
24 and on these ends are formed the abutments or
knots 35.
_ The lateral suspending members 3|, 32 of the‘
cable C and the cross length 33 thereof all lie in
15 the same plane as the members of the frame B.
It will also be understood that the ‘frame B'is'
rigid.
In operating the swing of the present invention
one child sits straddling each end of the seat
board 24 using the top rail I6 of the frame to
hold themselves with the hand and the bottom
rail serves as a perch for their feet.
To start
the swing in operation toward the left referring
to Figure l of the drawings, the child on the right
25 pushes bottom rail I‘! with his feet and pulls with
his hands top rail I6. During this movement
the child on the left remains inert neither push
ing with the feet nor pulling with the hands.
On the swing backwards from that described
.30 above, the child in the left pulls on top rail I6
and pushes bottom rail I‘! with his feet while the
chid on the right remains inert. Such exertions
alternately by the child on the right and the child
on the left will cause a swinging action on the
frame B.
During the swinging action the seat
board 24 remains substantially in a horizontal
plane. Cables I2, I3 serve to provide a back for
each end of the seat board to prevent the children
from falling off the seat board.‘
40
Since there are free portions of the cable mem
bers I2, I3 depending below the level of seat board
24 the cables I2, I3 move through the openings
34 as'these members alternately become loose
and taut when-the swing is in operation. With
the ends of members I2, I3 thus arranged as the
swing proceeds in one" direction the cable at the
back of the child will exert no pressure, while
at the same time the cable on the other end of the
seat board becomes taut and likewise no pressure
is exerted on the child’s back, since the body of
the child leans in the same angle as the cable.
While the cables I2, I3 and the single length
C are illustrated in the form of a limp rope it is
within the scope of the present inventon to use
chains'in their‘stead.
Having thus described the invention what is
claimed as new is:

pair of horizontal members for supporting the
65 frame so as to‘ swing back and forth,‘ a seat board
fulcrumed solely at its center across an inter
mediate portion of the third horizontal member
between the suspension ‘members and projecting
from both sides thereof to provide an equipoised
70 seat on both sides of the frame, and ?exible
means for engaging the opposite ends of said seat
board to limit movement about said center ful

members to provide abutments.
3. In a swing, an upright rigid frame, a pair
of lateral suspension members connected with
the ends of the frame for supporting the frame 20
