ANISM FOR WINDOW SASHES
‘
Harold Kenneth Sylvester, Hollywood, Calif.
Application December 14, 1936, Serial No. 115,664
3 Claims.
(01. 268-119) '
My present invention relates to the provision of
combined hinge- and operating and adjusting
mechanism for window sash, or similar closures,
and has for its object the provision of an organi
5 zation of few and simple parts which will occupy
but relatively little space and contribute ma
terially to the sturdiness, convenience and de
pendability in operation of the closure when
mounted and operated.
‘
10 I I have attained the foregoing objects by means
of the structure illustrated in the accompanying
drawings, in which
Fig. 1 is a fragmental elevation of a sash and
sash casing equipped with my combined hinge
15 and operator structure.v
Figs. 2 and 3 are plans, respectively, of the
casing and sash members of the upper hinge
element.
Figs. 4 and 5 are likewise plans, respectively, of
20 the sash and casing members of the lower hinge
element.
Fig. 6 is a fragmental section through the cas
ing showing the lower casing member in plan
with the top thereof removed, disclosing the
25 worm.
I
Fig. 7 is a view similar to Fig. 6 showing an as
sembly oflower sash and lower casing members,
the block 16 and worm 28 being sectioned, and
Fig. 8 is a View similar to Figs. 6 and 7 on a
30 smaller scale showing the sashin open position.
Similar reference characters refer to similar
parts throughout the respective views.
While sash and similar closures are old and
well known structures, they cannot yet be re
35 garded as completely satisfactory, and this is
particularly true with respect to hinged or French
sash which are a continual source of vexation to
owners and housekeepers, notwithstanding their
beauty and the convenience of being able to
40 swing the sash completely open or closed, or to
any intermediate position. There is nothing,
either theoretically or practically, to prevent the
assemblying of sash and casing with as much
nicety as may be desired except that it appears
45 to be the almost universal experience that swing
ing or French sash sooner or later sag and bind,
which involves the creation of unnecessary and
undesirable draughts. Also, the leaning out of a
window to grasp an outwardly swinging sash. is
50 regarded by a good many people as .an'unneces
sary hazard and an undesirable feature of their
operation.
As will hereafter be seen, my invention will
permit the opening and closing of the sash from
55 entirely within the room and the adjustment of
the'sash at any-desired‘ extent of opening as it
would require ‘great power to move the worm by
applying force to the sash while the sash may be.
moved by applying very little power to the worm.
As shown in Figs. 2 and 3 the casing member
I0 and the sash member ll of the upper hinge
element arev simple rectangular plates with off
sets l2 and I3 at one corner, the offset l2 of the
casing member being provided with a perforation
l4; and the offset I3 of the sash or closure mem- 10
her being provided with a pintle or trunnion [5 to
enter the perforation M. It is quite obvious
that the plates 'IB and H may be thickened to
secure. any desired degree of strength without
undulyincreasing the bulk of the structure.
15
The lower sash hinge member is similar to the
upper sash member except extending from the
face of the plate is an arcuate block l6, in the
curved portion whereof are formed teeth IT. The
center of curvature of the arcuate block I6 is at 20
the center of the offset l8, but, instead of pro~
viding this offset with a pintle, I provide it with
a bore or bearing It. The lower casing member
20 is likewise similar in plan or outline to the
upper casing member except extending from its 25
face is a block 2! complementary in plan to the
block carried by the lower sash member. That
is, instead of being convexly arcuate the block H
is rectangular with an arcuate recess 22 for re
ceiving the arcuate block of the lower sash mem- 30
her. The block 2| is split horizontally in the ver
tical center and recessed, at 23, to provide a hous
ing and bearings for the worm ‘M which is held
in its housing tangentially with respect to and in
co-operation with the worm gear 5? of the block 35
Hi. The inner end of the worm 24 is provided
with an angular embossment 25, or depression,
as may be desired, for co~operation with a pref
erably detachable operating handle or crank 26,
for the entry of which the block 2| is recessed 40
at 21, from its inner vertical face. The extended
corner of the lower frame member is provided
with an upwardly extended pintle 28 for enter
ing into and co-operating with the bore IS. The
two parts of the lower casing member may be 45
secured together by machine screws 2;‘! and all of
the members are transversely bored at 30, 36, etc.,
which bores are countersunk for attaching screws
3|, by means of which they are secured respec
tively to the frame and sash.
50
By providing a hinged construction and oper
ating means, the rotation of which is about
a single center or axis, I am permitted to greatly
simplify the structure and reduce its size, and at
the same time secure any degree of strength and 55

dependability in operation which may be deemed
necessary in any particular case.
The parts of the heretofore described organiza
tion may, if desired, be made by die casting,
which produces a product capable of withstand
ing atmospheric conditions and the life of which,
in such a situation, is inde?nitely extended.
Having described my invention what I claim
is new and desire to secure by Letters Patent is:
10
1. A combined supporting hinge and operat
ing mechanism for attachment to the top and
bottom edges within the plane of window sash
and the like comprising a plurality of hinging
elements arranged in spaced relation to swing
15 upon an aligning or common center, one of said
elements having ?xedly secured to the body
thereof within the plane of the sash to which it
is attached a worm gear, the center of which
coincides with the center of rotation of the ele
ment with which it forms a part, the comple
mentary portion of said last mentioned hinge
element being provided with a housing and jour
nal for a worm, and a worm mounted in said
housing and journal so as to engage and co-act
with said worm gear.
2. A combined supporting hinge and operat
ing mechanism for window sash and the like com
prising a plurality of hinging elements consist
ing or rectangular plates with o?sets at one cor
30 ner thereof, said plates being adapted to be ?xed
respectively at the top of the window frame and
to the edge at the top of the sash and to the edge
at the bottom of the sash and the bottom of the
window frame, the offset of a top plate and bot
tom plate being perforated and an offset of a top
and bottom plate being provided with a trunnion
or pintle to enter the perforation in the adjacent
plate, one of the plates attached to the sash
being provided with a worm gear developed from
the face and body of the plate about a center
coinciding with the center of revolution with the
member with which it is attached and the body
of the plate co-operating with said last mentioned
plate being provided with a housing and journal
for a worm and a worm mounted in said housing 10
and journal in co-operation with said Worm gear.
3. A combined supporting hinge and operat
ing mechanism for Window sash and the like com—
prising a plurality of hinging elements consist
ing of rectangular plates with offsets at one cor 15
ner thereof, said plates being adapted to be ?xed
respectively at the top of the window frame and
upon the edges at the top of the sash and the
bottom of the sash and the bottom of the window
frame, the offset of a top plate and bottom plate
being perforated and an offset of a top and bot
tom plate being provided with a trunnion or
pintle to enter the perforation in the adjacent
plate, one of the plates attached to the sash
being provided with a worm gear developed from 25
the face of the body of the plate about a center
coinciding with the center of revolution with the
member with which it is attached and the plate
co-operating with said last mentioned plate be
ing provided with a housing and journal for a
worm, a worm mounted in said housing and jour
nal in co-operation with said worm gear and a
detachable member for rotating said worm.
