I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Chartered Patent Agent, do hereby declare the nature
of this invention to be as follows:-
This invention pertains to improvements in window fasteners, and lifting cord
shoes, and has for its object the providing of a simple spring actuated bolt, adapted
to be locked against endwise movement in either direction; the providing of a
peculiarly constructed bolt case made in two longitudinal parts, one part having
arms adapted to be closed around the other part and unite the two parts together,
and the providing of a shoe adapted to slide in the window frame and constructed
to receive and hold the end of the weight cord.
A case is provided for the bolt which is adapted to be fastened to the window
sash, and to move endwise through the sash and engage openings or shoulders pro-
vided in the window frame. The bolt is provided with a projection entering a
longitudinal slot of the case, the said slot having off-sets at each end, so that the
bolt can be moved endwise and then by a slight lateral turn locked either in its
projected or withdrawn position. A spring is preferably provided which normally
holds the bolt projected, and at the same time holds the projection of the bolt
normally into one of said off-sets according to the position of the bolt.
The case is made in two longitudinal sections, so that the bolt and spring can
be readily placed in position therein, and one of the sections is provided with
arms adapted to close around the other section, and thus unite the two sections
together.
In one form I provide an oscillating end upon the handle end of the bolt, the
said end and adjacent end of the bolt casing having abutting shoulders, so that
instead of rotating the bolt for locking it the cap may be used for this purpose;
or the bolt can be operated as before described, and the oscillating cap used to
hold the bolt against rotation when the bolt is projected for locking the window.
In this event the cap is made movable endwise independently of the bolt slightly,
whereby the cap can be disengaged from the casing, and then the bolt turned to
disengage its projection from the off-set which will then permit it to be moved
endwise for unlocking the window.
I also provide a shoe adapted to slide in the window frame and provided with
an opening to receive a projection on the holt casing, and the opposite end of
this shoe is constructed to close around the end of the weight cord and secure it
thereto. In this construction the bolt is made sufficiently long to project through
the shoe into the window frame as will be readily understood.
Preferably the two longitudinal sections are provided in addition to the arms

page_text: for holding them together, with shoulders which also aid in holding them in their
proper relative arrangement.
The detail construction of the bolt and casing can be considerably varied with-
out departing from the spirit of my invention.

Improvements in Window Fasteners and Lifting Cord Shoes.
A communication from abroad by CHARLES J. CLARKE, of Kingsburg, in the
County of Fresno and State of California, United States of America, Gentle-
man.
I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Chartered Patent Agent, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to improvements in sash-fastening bolts and pertains
particularly to bolts adapted for use in connection with windows for locking them
in the desired position in the window frames. The object of the invention is to
provide a simple rotating endwise-moving bolt adapted to be readily applied to
the window, sliding shutter or the like to be locked and provided with means for
locking the bolt against endwise movement; and it consists in the special form
of case, whereby it is capable of separation to permit the bolt to. be readily placed
therein.
The invention relates also to the specific application of the bolt to window-
sashes supported in moveable shoes especially constructed to support the window-
sash and to have the window-sash cord attached thereto.
In the accompanying drawings, Figure 1 is a view of a bolt embodying the
invention, showing it applied to a window-sash. Fig. 2 is a detached perspective
view of the same. Fig. 3 is a longitudinal vertical section thereof. Figs. 4, 5, 6,
7, 8, 9, 10, 11, 12, 13, 14, and 15 are constructions showing slight modifications
but embodying the main idea of the invention. Fig. 16 is a detached perspective
view of the shoo which supports the sash and has attached thereto the sash-cord.
Referring now to the drawings, and particularly to Fig. 1, A represents a por-
tion of a window-sash, and B the window-frame, in which one or any other desired
number of recesses B₁ may be provided to receive the forward end of the bolt.
C is a shoe adapted to move in a groove formed in the window-frame B and
having attached thereto the sash-cord S, in a manner to be described hereinafter.
The bolt is placed in the window-sash by boring therein a suitable opening and
placing the body of the bolt within the opening, and the bolt-body is provided
with lateral arms P, having screw-perforations R, by means of which it is firmly
held in position, as will be readily understood. The projection Q is provided,
extending beyond the lateral flanges P, which is adapted to engage an opening T,
made in the shoe C. From this it will be seen that as the window-sash is moved
up and down it carries with it the shoe C, and the window is counterbalanced by
a weight attached to the sash-cord S, as usual.
The bolt-casing consists of the body portion G, having a reduced portion H at
its inner end, and the said body portion is preferably made in two parts, as clearly
shown in Fig. 2, which are provided with interlocking shoulders h, and the upper

page_text: parte is provided with the arms f, adapted to be forced around the lower portion
of the body of the bolt-casing, as clearly shown in Fig. 8. In Fig. 2 they are
shown as clamping the two parts of the body together, while in Fig. 8 they are
shown separated to enable the bolt to be placed to position therein and then the
other or lower part of the bolt-casing placed in position and the arms of then
forced inward and clamping the parts together. Just inside of the arms the
larger portion of the body is provided with the shoulder g, whereby the arms abut
thereagainst and prevent any relative outward movement of the two parts of the
body portion.
The bolt E is provided with a flange F within the large portion of the body,
and the bolt is normally held outward through the medium of a spring 2, placed
between the said lange and the reduced or contracted inner end of the body,
as clearly shown in Fig. 3, the spring also serving to turn the bolt in a locked
position.
The inner end of the reduced portion II is provided with a notch I, forming, as
will now appear, a lock by receiving a projection d upon a cap J. This cap J
embraces the inner extremity of the bolt E, and the enclosed end of the bolt with-
in said cap is provided with a reduced portion, as shown, which receives a
spring N, which abuts against a flange M at the extremity of the reduced portion,
and a pin K, which passes through a slot L, formed in the bolt, and has its end
connected with the cap. In this manner the cap is held normally inward, so that
when the bolt is in the position shown in Fig. 1 the projection is in engagement
with the notch I, and the cap cannot be rotated until it is drawn outward against
the tension of the spring N. Neither can the bolt E be rotated, as will be readily
understood, until the cap J is drawn outward and the projection d disengaged from
the notch I, and then the bolt may be rotated sufficiently to carry the projection i
from one of the laterally-projecting notches into the longitudinal notch, formed
in the enlarged portion of the body or casing of the bolt. The longitudinal open-
ing and the notches and form the ordinary construction for holding the
bolt against endwise movement after being moved endwise and rotated by the
spring 2 to have the projection engage therewith.
In Fig. 4 a modification is shown in respect to the body portion or casing of the
bolt. In this figure the projection Q is omitted, so that the bolt may be adapted
for use in other relations than that shown in Fig. 1; also, the lower half m of the
casing does not have its forward end entirely close the opening of the other half n
of the casing, as clearly shown in said figure; also, in this figure the locking-cap
is omitted. An additional interlocking projection and notch is shown in Fig. 4,
which assists in holding the two parts of the case firmly together.
Fig. 5 is a plan view of Fig. 4, showing the bolt projected and held locked under
the tension of the spring 2, Fig. 7, as will be readily understood.
Fig. 8 is a cross-sectional view showing the arms expanded for receiving the
lower half of the casing, and as this figure is merely intended to show the locking-
arms f no further description thereof is necessary.
Figs. 9, 10, 11 and 12 are views of a modified form, showing a locking-cap upon
the inner end of the bolt E, somewhat similar in principle to that shown in Fig. 1,
but different in specific construction. In this figure the reduced end II of the casing
is provided with the longitudinal slot 3 and lateral openings 4, with which a pro-
jection 5 is adapted to engage. The large portion of the casing has merely a
longitudinal slot 6, in which a projection 7 on the adjacent end of the bolt E pro-
jects and prevents the bolt E from having any turning movement. The projec-
tion 5 is a part practically of the rotatable locking-cap 10, which receives the
inner extension of the bolt E. Within the locking-cap 10 is a spring or other
tension device 12, which is merely to cause a frictional action between the cap
and the bolt, so that it will remain in the position to which it is placed-namely,
in either of the notches 4-and not be jarred therefrom.
The mode of operation of this modification consists in requiring the rotation
of the locking-cap 10 to disengage its projection 5 from either of the notches 4

page_text: into which it happens to be before the bolt can be moved endwise in either direc-
tion. From this it will be seen that the bolt is locked either in an inward position,
as shown in Fig. 12, or in an outward position, as shown in Fig. 9, and cannot be
moved endwise without first rotating the locking-cap 10, and by means of which
cap the bolt may also be drawn within the case, as will be readily understood.
Figs. 13, 14 and 15 are views of a modified construction in the casing, which is
constructed with a longitudinal opening 15, which extends through the large and
contracted portion of the casing, as shown. This enables the contracted portion of
the casing to be expanded to permit the bolt to be placed therein and then con-
tracted again around the bolt for holding it in position. The shoe C has one end
provided with the opening T for the projection Q of the bolt-casing and its opposite
end with the arms 17, which are adapted to close around and clamp the sash-cord.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. The combination of a longitudinally-movable bolt, a casing therefor, a lock-
ing-cap carried by the bolt, the cap and bolt having transverse abutting members,
uniting them to move together longitudinally, the bolt, cap and casing having
respectively longitudinal and transverse interlocking shoulders the parts operating
substantially as described.
2. The combination of a casing, a bolt movable longitudinally in the casing,
means for limiting the longitudinal movement of the bolt in said casing, a lock-
ing-cap upon the end of said bolt adapted to interlock with the bolt-casing and
prevent the turning of the bolt, whereby the bolt is locked in a projected or with-
drawn position from longitudinal movement and also locked from rotation, sub-
stantially as described.
3. A bolt-casing consisting of an enlarged and a contracted or small portion,
made in two longitudinal members, the members having interlocking shoulders,
and one of the members having securing contractible arms adapted to embrace
and secure the parts together substantially as described.
4. The combination of a casing having a projection, a bolt within the casing,
operating means for the said bolt, in combination with a shoe having its side walls
enlarged to form arms which are adapted to close around and hold the sash-cord,
said shoe provided also with an opening to receive the casing projection, said
bolt adapted to pass through and beyond the projection of the casing substan-
tially as described.
5. The improved window fastening apparatus shewn in and described with
reference to the annexed drawings.
