Improvements in Hinges for Windows.
I, CLIFFORD MCCLELLAN, of Room No. 5, Seventh Floor, Mills Building,
in the City and County of San Francisco, State of California, United States
of America, Attorney at Law, do hereby declare the nature of this invention
to be as follows :-
This invention relates to new and useful improvements made in the construction
of slip hinges for use on window-sashes of that class or description which are
hung and arranged to slide up and down in the 'window-frame and also to swing
like a shutter into the room.
The said improvements consist in a novel construction of hinge-butt comprising
a shank properly shaped to fit a square hole or socket in the stile or upright bar
of the window-sash, and having on the free end that projects from the socket a
hinge-pin or a knuckle to receive the pin of a similar shank that is fixed to the
window frame, which said other shank with its hinge-pin or its knuckle goes to
form the complete hinge.
The shank that is removably attached to the window-sash by being inserted in
the socket in that part is provided with a spring catch of peculiar construction to
engage a slotted face-plate or escutcheon of metal which is fastened to the
window sash over the hole or socket before mentioned, the said catch consisting
of a lever fitted to work in a longitudinal recess in one side of the shank and
confined therein to have a limited movement laterally by means of a pivot through
one end attaching it by that end to the rear end of the shank, and having also a
notch in the outer side near the unattached end which is turned or offset at an
angle in front of said notch to form an outwardly-standing finger-piece to the
latch. The said lever is pressed outwardly by a small helical spring placed in the
recess of the shank between the finger-piece of the latch, and the bottom of
the recess in the side of the shank.
By virtue of this construction the spring-latch serves to lock the shank of the
detachable part of the hinge when the same is inserted for operation in the socket
provided in the stile of the window-sash to receive it, at which time when the
shank is forced home in the socket the notch in the side of the latch engages the
edge of the face-plate around the socket and is held against it by the spring. In
that locked position the finger-piece end of the latch-lever projects beyond the
face-plate in position to be seized and pressed inwardly so as to disengage the
latch from the socket when the shank is to be unshipped.

I, CLIFFORD MCCLELLAN, of No. 5, Seventh Floor, Mills Building, in the City and
County of San Francisco, State of California, United States of America, Attorney-
at-Law, 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 new and useful improvements made in the construction
of slip hinges for use on window-sashes of that class or description which are hung
and arranged to slide up and down in the window-frame and also to swing like a
shutter into the room.
The said improvements consist in a novel construction of hinge-butt comprising
a shank properly shaped to fit a square hole or socket in the stile or upright bar of
the window-sash, and having on the free end that projects from the socket a hinge-
pin or knuckle to receive the pin of a similar shank that is fixed to the window-
frame, which said other shank with its hinge-pin or its knuckle goes to form the
complete hinge..
The shank that is removably attached to the window-sash by being inserted in
the socket in that part is provided with a spring-catch of peculiar construction to
engage a slotted face-plate or escutcheon of metal which is fastened to the window-
sash over the hole or socket before mentioned, the said catch consisting of a lever
fitted to work in a longitudinal recess in one side of the shank and confined
therein to have a limited movement laterally, by means of a pivot through one end
attaching it by that end to the rear end of the shank, and having also a notch in
the outer side near the unattached end which is turned or offset at an angle in
front of said notch to form an outwardly standing finger-piece to the latch. The
said lever is pressed outwardly by a small helical-spring placed in the recess of the
shank between the finger-piece of the latch, and the bottom of the recess in
the side of the shank.
By virtue of this construction the spring-latch serves to lock the shank of the
detachable part of the hinge when the same is inserted for operation in the socket
provided in the stile of the window-sash to receive it, at which time, when the
shank is forced home in the socket, the notch in the side of the latch engages the
edge of the face-plate around the socket and is held against it by the spring. In
that locked position the finger-piece end of the latch-lever projects beyond the
face-plate in position to be seized and pressed inwardly so as to disengage the
latch from the socket when the shank is to be unshipped.
The nature of this said improvement and the manner of constructing and
applying the same is explained at length in the following description in which the
accompanying drawing is referred to by figures and letters :-
In the said drawing
:-
Figure 1 represents in front-elevation a portion of the lower part of a sliding
and swinging window-sash and its frame, showing the two parts which go to form
a complete hinge secured in the sockets provided for them in the stile of the sash
and in the window-frame, and the hinge-pin of one part inserted in the knuckle on
the other part; the frame being partly broken away to expose the socket and the
shank inserted in it.
Figure 2 is a top-view of the shank secured in the window-sash, on which the

page_text: Knuckle is formed; the top-side of the shank being partly broken away to expose
parts of the latch.
Figure 3 is a side-view of the same piece with the latch-lever and its spring
removed.
Figure 4 is an end-view taken from the left-hand side of Figure 3.
Figure 5 is a detail plan and side-view of the latch lever.
Figure 6 is a front-view of the face-plate that is secured over the socket in the
sash or the window-frame.
A indicates the window frame in which a square mortise is cut of proper depth
to let in the shank B of the hinge-knuckle B*.
Over this socket for the shank B is placed a face-plate or escutcheon C having a
square hole C of proper size to take the shank B. This plate is fastened by
screws to the wood-work of the frame and is usually let in flush, with the surface
thereof.
F indicates the latch-lever attached by a pivot Fx to the inner end of the shank B
in a recess formed in one side of the shank to receive the lever, and formed with an
offset or outward bend from a point located about one third its length from the
outer unattached end, so as to produce an outwardly setting finger-piece or latch F³
standing normally out of the recess in the shank.
Behind this offset or finger-piece a notch F4 is formed in the outer side of the
lever to engage the edge of the plate C around the opening Cx, so as to lock the
shank firmly in the socket behind the plate C.
'A spiral-spring G placed in the recess of the shank behind the lever F holds
that part in engagement with the edge of the plate C, or under compression allows
the lever F to be closed into the recess of the shank sufficiently to disengage the
lever from the side of the socket and permit the shank to be withdrawn.
The outward movement of the lever F under the reaction of the spiral-spring is
limited by a laterally projecting foot F2 on the pivoted end of the lever located in
front of said pivot and arranged to engage a shoulder B3 at the back of the recess
in the shank, as shown in Figures 2 and 5 of the drawing.
As thus constructed and arranged for operation that part of the complete hinge
which carries the hinge-pin H is secured to the window-frame by setting the
shauk B into the opening C* in the socket provided for it in the frame, while
the other part of the hinge having the knuckle is similarly secured to the
window-sash a little above the line of the other part of the hinge that is
located on the frame and is placed in such a position that by closing down
the window-sash the knuckle will pass over and be seated on the hinge-pin H.
In this position the window-sash should stand partly raised from the sill, (as
represented in Figure 1,) so that by removing the beads on the inside of the
window-frame the sash will be free to swing into the room, it being understood
that one of these hinges is placed near the top and one near the bottom of the
window-sash. While the shank B is locked and held firmly in its socket by the
spring-held latch it is also easily released and unshipped when the hinge is
required by depressing the finger-piece until the notch is free of the socket-
plate.
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 :-
The herein-described slip-hinge, consisting of a straight shank having a knuckle
provided with an eye, and a similar shank having a knuckle with a hinge-pin to
take the eye of the other before-mentioned part, each shank having in one side a.
rigid-catch lever pivotally attached to the outer end of the shank in the recess
thereof, and having a lateral bend or offset in its length near the free end to form
a finger-piece and a spring notch in the outer side behind the said offset and a
spring behind said finger-piece arranged to press the same outward; the shank and

page_text: their catch-lever being combined and arranged for operation with a socket in the
wood-work of the window-sash and frame and a slotted face-plate over said socket,
as described and shown.
