PROVISIONAL SPECIFICATION.
Improvements in Devices for Opening, Closing, and Fixing Shutters.
I, JAMES WESLEY COLE, of Northampton, County of Hampshire, Massachusetts,
U.S.A., Clergyman, do hereby declare the nature of this invention to be as
follows:-
-
The device of this invention is adapted for operating and fixing in any desired
position shutters of the kind that are moved horizontally round upon hinges. The
shutter is turned by means of a square socket key which on the inside of the window
frame is placed on the squared end of a spindle passing through the window frame,
and by a bevel toothed pinion on its outer end engaging a horizontal bevel wheel
fixed on a vertical spindle the axis of which is co-incident with the hinges of the
shutter. The vertical spindle is prevented from lifting, by the pressure of of the
bevel pinion, by means of a stop taking over the horizontal bevel wheel, said stop
projecting from the bearing plate of the spindle passing through the window
frame. The inner end of this spindle is carried in a bushing let into the inner
side of the window frame. Said bushing is recessed for the reception of a square
apertured socket in which takes the squared end of the spindle passing through
the window frame. The socket on the edge which takes into the bushing is pro-
vided with semicircular notches which may be engaged by a round stud passing
into the bushing, half its diameter outside the semicircular notches, and the other
half engaging any one of the notches, except where the stud is recessed to the
extent of one half. According as a notch is released the spindle may be turned to
operate the shutter. The stud is fitted with a stop pin to limit its movement.

Improvements in Devices for Opening, Closing, and Fixing Shutters.
I, JAMES WESLEY COLE, of Northampton, in the County of Hampshire, and State of
Massachusetts, U.S. America, Minister, 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 improvements in shutter-operating devices, more parti-
cularly relating to means which is operated at the inside of the window-casing for
swinging the hinge-supported shutters or blinds and holding them locked and im-
movable in any of their positions, either wide open, closed, or in an intermediately-
sition

page_text: The object of the invention is to materially improve the construction of the
aforementioned devices whereby they are rendered simple, effective, and have
no liability of becoming deranged or bound; and to these ends the invention con-
sists in constructions and combinations of parts all substantially as will hereinafter
fully appear and be set forth in the claim.
Reference is to be had to the accompanying drawings, in which:-
Fig. 1 is a horizontal section through a window-casing and the hinged blind and
through or along the blind-operating devices.
Fig. 2 is a vertical section of the same, taken on the line 22, Fig. 1, the operating
kev or handle, which is shown in Fig. 1, being, however, in this' view. omitted: The
line 11 on this view, Fig. 2, indicates the planes of section on which Fig. 1 is taken.
Fig. 3 is a face view of fittings within the inner side of the window-casing, an
operating-spindle with the handle-knob being shown as in section taken on the
line-33; Fig. 2.
Fig. 4 represents in perspective, the parts seen in Fig. 3, all said parts being
detached and distinctive, one from the other.

In the drawings, A represents the window-casing having the blind, or shutter B,
which is of the usual well-known construction, hinged to the casing at a by the
employment of the usual form of hinges. At the hinged edge of the blind there
is mounted the bevel segment-gear c, which, as shewn, comprises three-quarters of
a circle and has the angular lug standing above its back, this lug overlapping
and fitting the edge and outer face of the appropriate member of the blind-frame,
being secured thereto by screws. The axis of the gear C is coincident with the
hinge a.
A hole f is bored horizontally through the window-casing from the inner
to the outer side, within which is introduced the arbor d which carries at its outer
end the bevelled pinion D, which is in mesh with the aforesaid bevel segment-
gear C. The aforesaid hole f is counterbored or enlarged within the inner face of
the window-casing, within which is set the bushing G, which constitutes the sup-
port and bearings for movable parts of the shutter operating and locking devices,
which will be shortly described.
The bushing consists of an annular disk having the lateral rabbet or depression g
within its outer face, and this part g furthermore 'has 'the rearwardly projected
tubular hub i, with the cress slot or kerf transversely placed near its inner end,
as clearly seen in the drawings, this cross-kerf having a depth of approximately
half the diameter of the said tubular hub i, and it intersects the bore of said hub i.
This bushing G, with its tubular hub i, is sunk within the vertical inner face of
the window-casing, within the enlarged' orifice of the hole f, which is formed
therefor, and is secured by the screws k.
Within the depression g of the bushing is provided the disk m, having the rearward
axial hub m², which latter protrudes through and rearwardly beyond the central
opening of the bushing. The disk and its said hub m² has the axially-extended
squared opening m² within the inner portion of which the correspondingly-squared
part of the pinion-arbor d enters with a non-rotatable engagement. The disk m
is adapted to receive, in the outer part of said squared opening m³, the squared
inner end of the key H, whereby the turning of the key, and thereby the disk,
causes the rotation of the arbor and pinion and the swinging of the blind. The
said disk is provided, marginally, with the semi-circular notches m³. A spindle o
is entered within the aforesaid tubular hub i, and this has the radially-projected
studo near its inner end, which, as the spindle is turned, moves within the afore-
said cross-kerf j, and by its abutment against the base of the said kerf at the one
or the other side of the axis of the hub, the half rotational movement of the spindle
are limited. This spindle is provided at its end farthest from that having the
stud with the handle-knob o³, whereby it may be conveniently turned, while next
within this handle-knob, and as seen at o, the spindle is recessed or slabbed, so
that the unrecessed parts of the spindle may, accordingly as the spindle is turned
to the one other of its extremes, lie within one of the marginal notches m³ of the
disk to lock the disk, and consequently the blind, or lie within the portion of the

page_text: socket for said spindle which is radially outside of the periphery of the disk m, then
leaving the latter free to be turned by the key to operate the blind. Upon the
outer face of the window-casing is the face-plate or bushing t, through which
passes the pinion-arbor d. This plate has the lug standing horizontally out-
wardly therefrom, in a plane for engagement with the upper face or back of the
beveled segment-gear C, and this serves as a stop to prevent the lifting of the
blind. The blind B which has a series of tilting-slats u and the vertical operating-
bar, individually jointed thereto, has below the end of the operating-bar
plate or casting w, with the series of outstanding lugs
the
like rack-teeth. The
bar has at its lower end the catch device which may swing on the bar and rela-
tively to the teeth w², so as to engage one or another of the latter, according to the
vertical adjustment of the bar, and thereby hold the bar and tilting slats in any set
position and against rattling.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
In a shutter worker and lock, the combination with the casing and blind, the
gear C, and the pinion D, with the arbor d, projected through a hole therefor in the
window-casing, the annular bushing G, secured within the inner face of the casing,
and provided with the tubular hub i, inwardly extended at one side of its axis,
which hub has the cross-kerf j, intersecting its axial bore, the disk m having the
marginal notches m5 and the hub m² in which the pinion-arbor has a non-rotatable
engagement, the spindle o rotatable within the said hollow hub 2 having the radial
stud o² to play in, and to be limited by the opposite base portions of the said cross-
kerf j, and provided outwardly with the handle-knob o³, and having the recessed
portion of next to the notched rim of the said disk, all substantially as and for the
purpose set forth.
