8 Claims.
This invention relates to garage doors, or sim
ilar doors, and particularly to those that are
adapted to open upwardly into an overhead open
Generally stated, the object of the invention
is to provide a novel and improved construction
and arrangement whereby a garage door of this
general character is constructed and mounted in
a way that will more satisfactorily enable it to
accommodate itself to varying conditions of door
way and building construction.
A special object is to provide a novel construc
tion and arrangement whereby garage doors of
this kind may be used in pairs, say, for a two-car
15 garage, in a manner that will tend to obviate the
necessity of using anything between them, inside
of the building, that might be quite liable to in
juriously engage the sides of the automobiles.
Another object is to provide a novel construc
20 tion and arrangement whereby the opening move
ment, as well as the closing movement, of the
door, is retarded at the end of either movement
by friction means that can be easily adjusted or
regulated to insure the desired retarding effect,
in accordance with the size and weight of any
particular door.
It is also an object to provide certain details
and speci?c features of construction tending to
increase the general e?iciency and desirability of
30 a garage door of this particular character.
To the foregoing and other useful ends, the
invention consists in matters hereinafter set forth
and claimed and shown in the accompanying
_ drawings in which
Fig. 1 is a vertical section of a garage door
embodying the principles of the invention, show
ing adjacent portions of the building.
Fig. 2 is a fragmentary perspective view of cer
tain portions of the support upon which the door
is mounted for opening and closing movement.
Fig. 3 is a perspective of one of the parts shown
in Fig. 2 of the drawings.
Fig. 4 is a horizontal section on line 4-4 in
Fig. 1 of the drawings, on a smaller scale.
Fig. 5 is an enlarged vertical detail section
on line 5-5 in Fig. 1 of the drawings.
Fig. 6 is a side elevation of the parts shown
in Fig. 5 of the drawings.
Fig. 7 is a diagrammatic view showing certain
of the elements of Figs. 5 and 6 in separated
condition and in perspective.
As thus illustrated, the invention comprises a
pair of upright rectangular garage doors I and I,
55 mounted in the two doorways in the front of
(CI. 20-16)
the garage building 2, as shown in Figs. 1 and 2
of the drawings. It will be seen that each door
is of a width to swing through its doorway, but
is preferably of a height to normally engage the
top portion 3 of each doorway immediately inside
thereof, as ‘shown in Fig. 1 of the drawings, while
in this closed position, each door has its lower
edge resting upon the floor of the garage.
Each door has a pair of upright angle irons 4
secured to the. back or inside thereof, and each
angle iron has its rearwardly extending flange
formed with a gap at 5, and the horizontal chan
nel irons 6 are mounted in these gaps or notches,_
as shown more clearly in Fig. 2 of the drawings.
To hold the channel irons 6 for endwise adjust 15
ment in these gaps or notches, guide plates Tare
bolted to the rearwardly extending ?anges of the
angle irons 4. For each door, there is a horizon
tal channel iron 8 bolted to the back or inside of
the door, with the adjacent end portions of the
channel irons 6 clamped therein by bolts 9 that
extend through the doors. The channel irons
8 may have holes or slots for said bolts, and the
channel irons 6 may also have bolt holes of this
character, whereby the channel irons 6 are ad 25
justable endwise in the channel irons 8, for doors
of different widths, or for different distances be
tween the sides of the building. The outer end
of each channel iron 6 has a right angle channel
arm section [0 secured thereto by rivets and 30
plates II, as shown more clearly in Fig. 2 of the
drawings, so that these horizontal and parallel
arms Ill are rigid with the channel irons 6, and
are thereby susceptible of adjustment toward and
away from each other, by means of the bolts 9 O: 5.
previously described. Each arm ID has a brace
Ill extending upwardly from a swivel eye 12 on
the arm to an eye 13 on a bracket plate [4 se
cured to the back or inner side of the door.
Thus, these braces l I I can assume different posi
tions, according to the distance between the arms
ill, for garage buildings having varying or differ
ent structural conditions. Each arm is pivoted
on the building at l5, and each arm is preferably
provided witha series of holes l6 for adjustably
connecting the lower end of a spring I'I thereto,
the upper end of each spring being preferably
fastened to the building at I8, by any suitable
or desired means.
Thus, each door normally occupies its closed
position, as shown in Figs. 1 and 4 of the draw
ings, but, with the assistance of the springs, may
be raised into the position shown in dotted lines
in Fig. 1 of the drawings, in which position the 55
lower end portion of each door rests against the
under side of the top portion 3 of its allotted door
way. The Springs help to raise the doors into
open position, and then cushion the downward
movement of the doors into closed position.
When two doors are arranged this way, as close
together as possible, something must be provided,
in an upright position, between the adjacent arms
II, to support the pivots l5 of these arms. If a
10 support of that kind should be vertical, it would
then be far enough within the building to en
danger the sides of the automobiles. Therefore,
to avoid such danger, an inclined ?xed support i9
is provided, which extends upwardly from a point
15 between the adjacent lower corners-of the two
doors, to a point above on the building some dis
tance back from the front of the building, so that
the upper and lower ends of this inclined support
are held in ?xed position. This inclined support
20 I! is of advantage, it will be seen, for the reason
that it provides clearance below it, at its lower
portion, for the wheels and foot-board and mud
guards of the vehicles, which are the things on
the automobiles that are most likely to be injured
25 by a side swerve in driving the vehicles into and
out of the building.
Preferably, each pivot I5 is constructed as
shown in Figs. 5, 6 and '7 of the drawings, in
order to provide a retarding friction at the end
30 of the upward movement of the door into open
position, and also at the end of the downward
and the disk 21 in unison, so that no friction is
exerted during the main portion of the opening
movement of the door. However, when the lug '
39 on the disk 21 strikes the ing 38 previously
mentioned, the rotation of the disks 26 and 21
is stopped, and the disk 23 then rotates alone
until the ends of the slots 25 engage the bolts
28 previously mentioned, and it is during such
?nal rotation of the disk 23 that su?lcient fric
tion is developed between this disk and the disk
21 to retard the end portion of the opening move
ment of the door. Thereafter, when it is desired
to close the door, all three disks rotate with a
swinging motion of the arm l0 until the ing
39 strikes the lug 31 previously mentioned, and 15
then again the disk 23 rotates alone in frictional
contact with the disk 26, thereby frictionally re
tarding the end portion of the closing movement
of the door. Preferably, each disk 21 is provided
with another lug 40, diametrically opposite the 20
lug 39, so that the same disks can be used either
at the right or the left. In this way, the plates
3| can all be alike, but those at one side will have
their lugs 31 and 38 into position to cooperate
with the ing 39, while those at the other side of 25
the doorway will be turned around to have their
lugs 31 and 38 in position to cooperate with the
lug 40 instead.
Thus, the pivot of each arm ID has a friction
device therein, that develops friction at the end 30
of the opening movement of the door, and at the
movement of the door into closed position. For
end of the downward or closing movement of the
that purpose, each arm I ll has a bracket plate
20 secured thereto, as by means of bolts inserted
door, su?lciently to bring the door softly and
easily into open position, and softly into closed
position, when the friction devices are properly
adjusted or regulated to insure the desired or
requisite degree of friction necessary for that
through holes 2| in said plate, and through the
arms. Each plate 20 has a squared hub portion
22, and a metal disk 23, with a su_bstantially rec
tangular opening 26, is mounted on said squared
portion of the plate, the squared portion extend
40 ing through and substantially ?tting this open
ing. This disk 23 is also provided with diametri
cally opposite curved slots 25. A disk 26 of as
bestos, or other suitable ?brous material, en
gages the face of the disk 23, and a cup-shaped
45 or ?anged disk 21 has its inner flat surface
arranged to engage the other side of the disk 26,
as shown in Fig. 5 of the drawings. Bolts 28 are
inserted through all three disks, and through the
slots 25, to clamp the three disks together, and
50 by means of these bolts the friction between the
disks can be adjusted or regulated to suit the
conditions, and in accordance with the weight
of the door and the tension of the said springs.
The disks 26 and 21 are provided, respectively,
55 with round openings 29 and 36 to receive the
hub portion 22, so that these disks 26 and 21 will
have rotary movement on said hub, while the disk
23 is held against rotation on said hub and will
move in unison with the swinging movement of
the arm l0, when the doors are opened and closed.
A bracket plate 3| is secured to the building, in
rigid and stationary position, for each pivot i5;
and for each pivot, there is a stud 32 extending
through the bore or opening 313 of the plate 20,
65 formed at its outer end with a head 34, and at
its inner end with a reduced portion 35 which ex
tends through the opening 36 in said bracket
plate, this reduced portion 36 being riveted over
to make the stud 32 rigid with said bracket plate.
70 The latter is also provided with outwardly bent
lugs 31 and 38, arranged substantially ninety de
grees apart, as shown. With this arrangement,
when a door is raised into open position, the disk
23 of each pivot turns on the axis of the latter
TI and, by frictional contact, rotates the disk 26

that disclosed in copending application to same 40
inventor, Serial #97376, ?led Aug. 26, 1936.
What I claim as my invention is: -
1. In a garage door, a single rigid door section
normally in vertically disposed position in the
doorway of the building, a horizontal arm rigid
with and extending at right angles to the back
or inside surface of the door, an inclined ?xed
support extending upwardly and inwardly of the
doorway, from a point adjacent the lower corner
of the door, at the front of the building, to a 50
point above and in rear of its lower end, and a
pivot for said arm, on said inclined support, the
latter providing clearance below its lower portion
for the mud-guards and foot-board of an auto
mobile, the door thus constructed having a hori
zontally disposed overhead open position, when
moved upwardly about the axis of said pivot.
2. A structure as speci?ed in claim 1, compris
ing another similar door, with a similar rigid arm,
the two doors being side by side in the same ver 60
tical plane, and a pivot for the latter on said
inclined support, so that the latter is between
the two arms, whereby the clearance below said
inclined support is eii‘ective for an automobile
at either side thereof.
3. In a garage door, asingle rigid door sec
tion normally occupying a vertically disposed po
sition in the doorway of the building, a horizon
tal channel iron on the back or inside surface of
the door, the length of said channel iron being 70
less than the width of the door, horizontal par
allel arms joined to sections of channel iron that
are slidable endwise in the channel of said ?rst
mentioned channel iron, so that the distance
between said arms may be changed, vertically 76
disposed angle irons on the back of the door,
provided with guiding means for said adjustable
sections of channel iron, and pivots for said
arms on the structure of the building, whereby
the said door has a horizontally disposed over
head open position.

tion in the doorway of the building, an arm rigid
with the inside surface or back of the door, and
a pivot for said arm on the structure of the
20 building, said pivot comprising a polygonal hub
ing lugs, with a‘ projection on the periphery of
said third disk operating between the lugs on
said bracket plate, and a stud inserted through
the arm and hub and fastened to said bracket
plate, so that said arm and hub and ?rst-men
tioned disk oscillate in unison about the axis of
said stud, and said curved slots permitting slip
page between disks, thereby providing lost mo
tion retarding friction for the end portion of
both the opening or closing motion of the door. 10
6. A structure as speci?ed in claim 5, the lugs
on said bracket plate being spaced substantially
ninety degrees apart, on the line of a circle
struck from said axis.
7. A structure as speci?ed in claim 5, said third 15
disk having another projection diametrically op
posite its ?rst-mentioned projection, so that this
disk can be used as either a right or a left, with
bracket plates which are exactly the same in
form, but differently positioned on the build 20
on said arm, a metal disk provided with a cen
ing structure.
tral opening formed to receive said hub, and
with curved diametrically opposite slots, a disk
of friction material engaging said ?rst-mentioned
disk, a third disk having bolts extending through
the friction disk and the slots of the ?rst disk,
a stationary bracket plate secured to the building
8. A structure as speci?ed in claim 5, said ?rst
mentioned disk being held against rotation rela
tively to the arm, by the engagement of the disk
with said hub, but the other two disks having 25
oscillatory motion upon and relative to said hub,
