Improvements in Shutter Operators and Fasteners.
We, HERMANN SCHILLING, of Spencer Street, Amsterdam, in the County of
Kenton, and State of Kentucky, all of United States of America, Gunsmith, ALVIN
WELLING, of Nos. 243 and 245, Pike Street, Covington, also in said County of
Kenton, and State of Kentucky, Liquor Dealer, and Louis FRITZ, of Nos. 171
and 173, West Robins Avenue, also of Covington, in the County and State afore-
said, Manufacturer, 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 certain improvements in shutter-workers such as are
adapted for use in opening and closing window-shutters without necessitating the
opening of the window; and the object of the invention is to provide a device of
this character which shall be simple and inexpensive in construction and shall be
adapted to hold the shutter when either in opened or closed position securely
against movement, whereby slamming of the shutters by the wind or opening
thereof from outside the house is prevented.
The invention consists in certain novel features of the construction, combination
and arrangement of the several parts of the improved shutter-worker, whereby
certain important advantages are attained and the device is made simpler, cheaper
and otherwise better adapted and more convenient for use than various other devices
heretofore employed, all as will be hereinafter fully set forth. The novel
features of the invention will be carefully defined in the claims.
In the accompanying drawings which serve to illustrate the invention."

In the views, 1 indicates the sides of the window-casing, and 2 indicates the sill
thereof, while 3 indicates the shutters hinged to the outer edges of the sides 1 of

page_text: the casing by means of butt-hinges 4, as will be readily understood. One of the
shutters is provided in, the ordinary way with a projecting tongue or bead 5
extending along its edge in position to overlap the edge of the other blind or
shutter when the shutters are closed, and on the inner side of the shutter having
said tongue is secured, as seen in Figure 10, a plate 6, having a depending lug 7
adapted, when the shutter is closed, to enter a recess S in the outer edge of the
sill 2, as seen in Figures 1 and 10, in position to he engaged by a locking-piece
or cam 9, arranged in said recess and held on the end of a rotative stem 11
extending transversely through the casing-sill to the inside of the house. The
locking-piece 9 is circular in form, as shown in Figure 8, and is provided with a
Hattened side 10 adapted, when said piece 9 is properly turned, to permit the
log 7 to pass over it into the recess S in position to be properly engaged with said
piece 9. The locking-piece 9 is also preferably formed integrally with the stem 11
on which it is held, and said stem passes through an escutcheon-plate 12 at the
inner surface of the sill 2 and is provided with a flattened handle or thumb-piece 13
secured therein by means of a screw 14 or the like and serving to prevent the stem
from moving lengthwise through the sill as well as to permit said stem to be
readily turned to lock the shutters in closed position.
To operate the shutters 3 two similar devices are employed, one at each side of
the sill, these devices being, as shown in Figure 2. reversed, so as to permit of
the proper movement of the shutters in opening and closing them, as will be
readily understood. As the devices are similar to each other in other respects,
we will only describe one of them in detail. Ench of said devices consists of a
metal plate or frame 15, embedded or let into the sill 2 of the casing, which is
provided with openings or recesses 16 for this purpose. 17 indicates the top or
body portion of the frame or plate 15, extending along the top of said recess 16
and provided with a beveled or angular side along which is a raised wall 1$
extending below said body portion and provided with a projecting circular and
centrally-perforated bearing-plate 20. spaced apart from said body-portion and
adapted to receive in its central opening a boss 21 formed on a crank-arm 22,
which is held to turn in the space between the bearing-plate 20 and the body-
portion 17 of the frame. The loss serves to hold said crank-arm in proper posi-
tion, and said arm is formed with a reduced end-portion 23 to which is pivotally
connected the end of a link 24, extending out through the opening 16 in the sill
and coupled at its outer end to one arm of a bell-crank lever 25, pivotally mounted
in a slotted opening 27 on a pin 26 which is secured in the bracket 28 in which
the slot is formed. The construction of said bracket. 28 is clearly shown in
Figure 7, which is an enlarged perspective view of this part. The bracket 28 is
secured by means of screws or the like to the outer side of the casing-side I as
shown in Figures 2 and 5. near the bottom of the shutter 3.
The lever 25 is slotted, as shown at 29 to receive a pin 50, formed on a plate 31,
secured to the lower edge of the shutter, so as to form a connection between the
outer end of the link 24 and said shutter, to permit of operating the shutter, the
slot 29 serving to compensate for the differences in the extent of movement of the
shutter and the working parts of the device.
The boss 21 of the crank-arm 22. is formed with a squared socket 32 as clearly
shown in Figures 2, 6, and 9, with which socket is engaged the squared lower end
of a shaft 34, extending up vertically in the sill 2 of the casing and having its
upper end also formed with a square 36 projecting above the level of the sill in
position to be engaged by an operating handle 37 having a squared opening to
receive said end 3 of the shaft, and by means of which the shaft may be readily
turned through a partial rotation back and forth to permit the shutter to be
opened or closed. The sill 2 is provided with an escutcheon-plate 35 through
which the shaft 34 passes as clearly shown in Figure 4, and in order to hold said
shaft in position it is provided with a projecting pin 34" beneath the plate 35
and playing in a recess BS in the sill.
The raised edge-wall 18 of the frame or plate 17 forms a stop to limit the

page_text: movement of the crank-arm 22 in one direction, being recessed, as shown at 39,
to receive the end of said arm, and in order to limit the movement of said arm
in the opposite direction, we provide the frame with an overhanging web 40
extending from the bearing-plate 20 to the front end of the frame, as clearly
shown in Figures 2, 5 and 9.
In operation, when it is desired to open or close the shutters, the handle 37 is
applied to the squared ends of shafts 34, as shown at the right in Figure 1, and
moved so as to impart a partial turn to the shaft and to the crank-arm with
which the lower end of the shaft is engaged. The movement of the crank-arm is
communicated through the link 24 to the elbow or bell-crank lever 25 and through
the connection between said lever and the shutter, to said shutter so as to swing
the same upon its hinges into opened or closed position, as the case may be.
When the shutters are in closed position, they may be securely fastened by means
of the locking-piece 9 so as to prevent them from being opened from outside the
house. The parts of the device are so proportioned, moreover, that the crank-
arm 22 has imparted to it, when moved to its fullest extent in opening the
shutter, a slight extent of movement greater than is imparted to the shutter
operated from it, so that when the crank-arm stands in engagement with its
stop 39, as shown in Figure 2, its point of connection with the link 24 will be
out of line with the axis of shaft 34 and the point of connection between the link
and bell-crank lever 25, so that closing of the shutters from outside the house
prevented. By this construction, slamming of the shutters by the wind is pre-
vented, and at the same time the ready operation of the shutter by means of the
handle 37 is not interfered with in any way.
From the above description of the improved shutter-worker it will be seen that
the device constructed according to our invention is of an extremely simple and
inexpensive nature and is especially well adapted for the purposes for which it is
designed, and it will also be apparent that the device is capable of some modifi-
cation without material departure from the principles and spirit of the invention
and for this reason we do not wish to be understood as limiting ourselves to the
precise form and arrangement of the several parts herein set forth. For example,
in some cases the handle shown in Figure 4 may be dispensed with and the con-
struction shown in Figure 11 employed. As shown in this view, the upper end
of the shaft 34 is made flush with the upper surface of the sill 2 and is formed
with a squared socket to receive a squared projection 41 on the under side of the
handle 37.
