Improvements in Pivotal Supporting Devices for Window Sashes,
Doors, and the like.
I, GEORGE HENRY PARKER, of 1453, Monadnock Buildings, Chicago, Cook
County, Illinois, United States of America, Gentleman, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention relates to a novel device for affording temporary pivotal support
to a window sash, door, or the like sliding, stationary or non-pivotal object, by
which such object may be pivotally sustained as on hinges, while being moved
or swung out of its natural position.
A. device embodying my invention is mainly intended for attachment to a win-
dow jamb and sash, so that the latter may be swung out of the jamb to admit of
cleaning both sides of the same but the same features of constructon may be
employed to pivotally support other objects.
As shown in the accompanying drawings.

page_text: Figure 14 is a face view of a holding plate attached to the jamb.
Figure 15 is a sectional view of a modified form of the device when pro-
vided with a vertically movable bracket or hinge member.
As shown in the said drawings, Figures 1 to 5, A indicates the jamb and A¹
the sill of a window, said jamb being provided with a stop a and parting strip a¹.
in the usual manner. B indicates the vertically sliding lower sash and B₁ the
similarly arranged upper sash of the window. C indicates a vertically arranged
connecting bar or rod, on the ends of which are mounted hinge-members or
brackets D D¹, E E', of which the brackets D D are adapted for attachment
to the jamb and the brackets E E are adapted for attachment to the sash.
The pairs D E and DE¹ of the brackets are located at opposite ends of
said rod. One bracket of each pair of brackets is affixed to the pivot rod, while
the other bracket is adapted to rotate or turn thereon; the fixed brackets in the
instance illustrated, being those marked DD₁, which engage the jamb.
To now describe in detail the construction of said brackets, the same are illus-
trated more clearly in Figures 2, 3 and 4, which show the upper brackets D
and E and the same will be described in connection with said upper brackets, it
being understood that the lower ones D¹ E¹ are similarly constructed. The said
brackets have base or back plates, de, which are provided with vertically arranged
-open-ended-slots, del, adapted to receive the headed studs G, H, upon the jamb
and sash. Said studs, as shown in these figures, are formed by screws-inserted
into the jamb and sash. The slot el on the upper bracket E, which engages the
sash, opens upwardly, while the slot d' of the lower bracket D, which engages the
jamb, opens downwardly. The back plates ed are, moreover, herein shown as
mado integral with the main parts of the brackets and as joined to the brackets
by integral side walls; the body parts of the brackets, together with the bottom
plates and connecting side walls forming vertical recesses in the bases of the
brackets adapted to receive the heads of the studs when the shanks thereof are
inserted into the slots ed-The-said-back-plates are preferably made thicker at
the outer than at the inner ends of the slots d' el, so that they will act with a
slightly wedging action to bring the heads of the studs in close contact with said
back plates when the brackets are engaged with said studs.
In engaging the brackets thus constructed with the jamb and sash, the sash is
first raised until the stud H therein is above the stud on the jamb, and the lower
bracket D is then drawn downwardly over the head of the stud on the jamb, until
the latter reaches the inner end of the slot and the flat face of the bracket is
brought in firm contact with the jamb. The sash is then lowered so as to bring
the head of the stud thereon downwardly into the slot el of the upper bracket E;
it being, of course, understood that when the sash is thus engaged with the upper
bracket the weight of the sash is carried by the upper bracket resting on the
lower one;
the two parts of the bracket acting like the members of a hinge.
In order to protect the face of the jamb and sash from wear or injury by con-
tact of the brackets D and E therewith, when the studs G and H are formed by
screws, as shown, said screws are provided with washers gh, which are counter-
sunk in the jamb and sash so as to be flush with the surface thereof. Said washers
are, moreover, preferably provided with integral sleeves g¹ h¹ which surround the
shanks of the screws adjacent to its head and come in immediate bearing against
the sides of the slots de¹. Said sleeves not only prevent wear from coming
directly on the shanks of the screws, but also operate to accurately determine
the distance of the screw heads from the face of the jamb and sash at the time of
inserting the screws while making stiffer and stronger the projecting portions of
said screws.
The rod C, in the construction shown, forms the pivots for both pairs of brackets
and both brackets D and E and D and E may turn on said rod, but as herein
shown and preferably constructed, the brackets D D₁ are rigidly attached to the
rod, preferably by means of cross pins cc inserted through the parts; this con-
struction serving to retain the said brackets DD' constantly in alignment with

page_text: each other, so that they will always project at the same side of the rod, and avoid-
ing the necessity of adjusting them by hand when engaging them with the studs
on the jamb. To retain the upper bracket E from end wise movement on the rod
a thimble C is secured to the upper end of the rod, preferably by a screw-threaded
joint, the lower edge of said thimble forming a shoulder which bears against the
bracket to hold it in place on the rod. To retain the lower bracket E¹ from end-
wise movement on the rod, the latter is shown as provided with a collar C³,
(Figure 1), located above the said lower bracket E. A stop projection e³ is provided
on the bracket of each pair in position for contact with the upper bracket when
the latter is in position at right angles with the lower brackets. By turning both
upper brackets by hand until in contact with said stop, the said upper brackets
will be brought into position for engagement with the sash before the parts are
applied to the jamb.
Both sets or pairs of brackets being permanently connected with the rod C and
being also adapted for detachable engagement with the headed studs on the jamb
and sash, it is obvious that the supporting device described, consisting of the said
brackets and connecting rod, constitutes a complete device, having no detachable
parts, which is placed in its operative position only when required for use; the
only parts which need to remain permanently on the jamb and sash being the
headed studs. Moreover, a number of windows may be provided with the headed
studs, and one supporting device only need be employed for operating on all of
the several windows.
The operation of the device described is as follows:
It being desired to swing the sash out of the jamb for washing the window or
any other purpose, the lower sash is raised a short distance, and the device is
placed against the jamb with the brackets D) and D¹ above the studs therein. The
rod is then moved downwardly, carrying the brackets with it, until the said
brackets are properly engaged with said studs. The swinging brackets E E¹,
having been placed with their base plates in contact with the sash, if the sash be
now lowered, the headed studs therein will be similarly brought into engagement
with the base plates of said last mentioned brackets. The window stops at the
side of the window, opposite to that at which the supporting device is applied,
may now be removed to release the same; the cords connecting the sash weight
with the sash may then be disconnected from the sash and the released edge of
the sash then swung outwardly into the room, the weight of the sash at this time
being sustained by the supporting device, in an obvious manner.
The connecting rod C, arranged as described, not only affords permanent con-
nection of the pairs of brackets with each other, but also serves as an important.
aid to the studs in holding the brackets in alignment with each other under the
strain arising from the weight of the sash, which, in the absence of said rod, would
obviously bring a heavy strain on the studs, due to the leverage of the brackets,
thereon, it being obvious that the said rod, by rigidly connecting the brackets,
prevents the same from acting independently on their respective studs, in a man-
ner to draw them outwardly from the jamb and sash. The rod, being engaged
with the movable brackets which are attached to the sash, obviously holds the same
in alignment equally with the other brackets, which are rigidly attached to the
said rod. Said rod, moreover serves to permanently connect the upper and lower
brackets, so as to constitute a supporting device having no loose or separable parts
to be handled in the use of the device, while at the same time greatly simplifying
the operation of applying the device to the window, because enabling both the
upper and lower brackets to be secured at one operation to the jamb by merely
moving downwardly both the said brackets when the same are pressed against
the jamb at points over the studs.
In Figure 5 I have shown in plan view supporting devices, such as have been
described, as applied for supporting both the upper and lower sash of the
window, both supporting devices being alike, except that, to adapt them to windows

page_text: as usually constructed, in the case of the device for the upper sash, the brackets
which engage the jamb are inclined or curved to give an offset position of their
bases, so that the brackets may fit against the parting strip a', when their pivotal
axis is located at a proper distance outwardly from the face of the sash. In
the drawing, Figure 5 shows both brackets D and E as made of the same shape,
but obviously the bracket E, in the case of the support for the upper sash, may
be made of the same shape as that shown in connection with the support for the
lower sash.
A pivotal supporting device, made as described, shown in Figures 1 to 5,
is adapted principally for use in connection with the vertically sliding sash or
like object which has vertical movement, in a manner permitting the studs
therein to be brought into engagement with the swinging brackets after the
stationary brackets have been secured to the jamb. Where the sash or other
similar object to be pivotally supported is a fixed one or has no vertical movement,
it is necessary, in order to produce engagement of the hinge members with the
sash, that one of said hinge members should have vertical movement with respect to
the other one. A construction of this kind is shown in Figures 6 to 10, the
same being illustrated in Figure 6 as applied to the left hand side of a large
stationary window. As shown in said figures, A2 indicates the window jamb,
and A the sill thereof, said sill being provided with a removable strip or stop A
which may be taken off along the vertical stop on the opposite or right hand
side of the jamb, to permit the sash to be swung outwardly or into the room when
sustained by the supporting device.
As shown in said Figures 6 to 10, I indicates a connecting rod, JJ, stationary
hinge-members secured to the upper and lower ends thereof, and KK swinging
brackets which are pivoted on the rod I, and are located beneath the brackets JJ
Said brackets K K are movable vertically on the rod so that they may be engaged
with and disengaged from holding studs or screws M M secured in the sash. The
means for giving movement to said-brackets-K-K-is-shown-in-Figures-7-and-8-in-
connection with the uppermost brackets J and K and is constructed as follows:
The rod I is provided, below the bracket J, with a screw-threaded portion which
is engaged by a screw-threaded sleeve N, the upper end of which has bearing
against and supports the said bracket K. To afford connection between said
sleeve and the bracket K by which the bracket will be moved in both directions
with the sleeve, said bracket is provided with a cylindrical recess adapted to receive
the upper end of the sleeve and the said sleeve is provided with an annular
groove n which is engaged by a screw stud k¹ inserted through the bracket and
entering the said groove. The sleeve N is desirably provided with a knurled
collar to facilitate the turning thereof by hand.
When applying to a window or like object the device last described, the sleeve N
at the top of the rod and the corresponding sleeve at the lower end thereof are
turned on the rod until the brackets KK are carried downwardly a distance
greater than the depth of the locking slots therein. The brackets JJ are then
engaged with the studs LL' on the jamb and the brackets K K' brought beneath
the studs on the sash. The sleeves N N¹ are then rotated to carry the brackets K K¹
upwardly until they are brought into contact with the brackets J J and the studs
on the sash are inserted in the slots of said brackets. When this is done the
sash may be swung outwardly upon the pivotal support afforded by the parts in
the same manner as herein before described.
The brackets J J K K¹ as shown in the figures last referred to are provided with
two sets of slots, while two sets of studs LL M M¹ are provided on the jamb and
sash, this construction being employed where the sash is a heavy one, as is usually
the case with stationary or non-sliding windows.
In Figures 11 to 14 I have shown a form of pivotal supporting device differing
somewhat from those illustrated in the preceding figures, but containing some
of the principal features of my invention. In these figures 0, 0, P, P¹ indicate
pairs of brackets which are connected by separate pivots Q, Q. The brackets O O¹

page_text: which are adapted for attachment to the jamb, are, in this instance, connected
by a rod or bar R, which is permanently attached to its end or cast integral with
the said brackets. The rod or bar thus arranged obviously serves the same general
purpose as the connecting rod herein before described, although, in this instance,
it does not serve to afford pivotal connection between the brackets; it being obvious
that such rod R affords permanent connection between the upper and lower
pairs of brackets, and serves to hold said brackets in alignment with each other
and to thereby aid in maintaining them in proper position under the strains
due to the weight of the sash. It is also obvious that, by reason of the pivotal
connection between the brackets, said connecting rod serves to hold the swinging
brackets which are connected with the sash also in alignment with each other,
although the rod in this instance is not directly engaged with the last mentioned
brackets as in the devices shown in the Figures 1 to 10 inclusive.
The means for connecting the brackets with the jamb and sash illustrated in said
Figures 11 to 14, is somewhat different from the construction illustrated in the
other figures of the drawings. Such means, in the case of the brackets 0,0¹,
consist of headed lugs o o' on said brackets, engaging slotted plates S S¹ (Figure 11),
secured in the jamb flush with the surface thereof. In the case of the
brackets PP, studs tt are affixed to plates TT secured in the face of the sash
flush with the surface thereof; said studs being adapted to engage vertical
slots formed in back plates p of said brackets in the same manner as before
described. Obviously, in the case of the brackets which are attached to the jaml
the interlocking devices on the bracket and jamb may be of a form having
projections or studs on the brackets adapted to enter recesses in the jamb, but in
the case of the brackets which are to be connected with the sash it is desirable
that the interlocking part on the sash should project from the same, because the
engagement of the brackets with holding device on the sash is accomplished by a
sliding movement of the brackets along or in contact with the face of the sash;
this being true both with respect to the form of supporting device especially
adapted for sliding windows, as shown in Figures 1 to 5, and for non-sliding
windows, where one bracket is movable vertically with respect to the other bracket,
as shown in Figures 6 to 10.
In
In Figure 15 is shown a modified construction of the form of support illustrated
in Figures 6 to 10 which is adapted for use in a construction where one or both
brackets of the upper and lower pairs of brackets are directly joined by a
connecting rod so that a device applied to give vertical movement to the vertically
movable bracket of one pair of brackets will act on the corresponding bracket of
the other pair through the rigid connection afforded by said connecting rod.
this instance U indicates a bracket adapted for attachment to the jamb by means
of a headed stud and which is joined to a corresponding bracket by a vertical
connecting rod W. V indicates a lower vertically movable bracket which is
pivotally connected with the bracket U by means of a pivot X. Said pivot X is
affixed in the upper bracket U and is provided in its lower end with a screw-.
threaded part u on which is placed a screw-threaded sleeve or nut X'; said nut
being provided with wings by which the nut may be easily turned by the
fingers. Obviously the nut X will operate to elevate the lower or movable
bracket V in the same manner as the sleeve W shown in Figures 6 to 10.
So far as the general features of my invention are concerned the same may be
carried out by the employment of any suitable parts on the brackets adapted to
interlock with complementary holding devices on the iamb and sash, where such
interlocking means are adapted to be brought into their interlocked position by
relative vertical movement of the brackets and the holding devices on the jambs
and sash. Such relative movement of these parts, in the case of the form of
support shown in Figures 1 to 5, is accomplished by a downward movement
of the sash to bring the holding devices into engagement with the brackets and in
the case of the form shown in Figures 6 to 10 by the upward movement of

page_text: movable brackets into engagement with the holding devices on the stationary
sash.
An important feature of my invention is embodied in a construction in which
two or more pairs of pivotally connected brackets are joined by a bar or rod in
the manner and with the advantages hereinbefore described and so far as this
feature of the invention is concerned, said rod may form pivots for the brackets,
as shown in Figures 1 to 11, or may be separate from the pivots, as shown in
Figures 11 to 15. Moreover, such a connecting rod may be attached to either or
both sets of brackets. The construction shown in which the connecting rod forms
the pivots for the brackets has, however, the advantage of greatly simplifying
the construction of the device, and this feature is herein claimed as part of my
invention.
While the main features of the invention herein claimed may be carried out
by the employment of details of construction differing from the specific ones
illustrated, yet certain of the details and features of construction shown are
in themselves novel and are herein claimed as a part of my invention.
While I have shown a supporting device, as provided with two sets of brackets
or hinge-members, yet it will be understood that my invention would be equally
embraced in a construction having three or more sets of brackets connected by a
rod, it being obvious that the results-described will be equally secured whether
there be two or more than two sets or pairs of brackets employed, as all-of-the-
brackets may-in-any case be engaged at the same time with the holding
devices attached to jamb and sash. Obviously, in the case of-a-very large or heavy
window sash, shutter, door or the like, it may be desirable to employ, three, four
or even more sets of brackets with a single rod, in order to avoid making the
brackets themselves unduly large or heavy so as to withstand the weight of the part
to be supported.
Having now particularly-described-and-ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare-that-what-
