STEPHEN McCLELLAN, OF SAN MARCOS, TEXAS.
SASH-FASTENER.
SPECIFICATION forming part of Letters Patent No. 479,152, dated July 19, 1892.
Application filed April 15, 1892. Serial No, 429,351, (No model,)To call who it macy concern:
Be it known that I, STEPHEN MCCLELLAN,
a citizen of the United States, residing at San
Marcos, in the county of Hays and State of
5 Texas, have invented certain new and useful
Improvements in Sash-Locks; and I do declare
the following to be a full, clear, and exact de-
scription of the invention, such as will enable
others skilled in the art to which it appertains
io to make and use the same, reference being had
to the accompanying drawings, and to the let-
ters of reference marked thereon,which form
a part of this specification.
My invention is a window-sash lock; and it
15 consists in the novel construction and arrange-
ment of its parts.
In the accompanying drawings, Figure 1 is
a face view of my lock attached to a window-
sash. Fig. 2 is a longitudinal sectional view
20 of my lock. Figs. 3 and 4 are detail views.
Figs. 5, 6, 7, 8, and 9 are figures showing
modifications of my invention, all being oper-
ated, however, by the same principle and hav-
ing in view the same ends.
25 My lock consists of a face-plate a, having
in it a longitudinal slot b and cross-slots c.
The said plate also has two perforated lugs d,
so that the lock may be secured to the edge
of the sash. Said lugs are each provided with
30 a neck e, which is squarely turned up and the
lugs squarely turned out, so that the lock
will set a little in from the face of the sash
and will not stand out and be in the way of
the lower sash as it is moved up and down.
35 The front end of the said plate has a perfo-
rated nose f, which is squarely turned back
to form a guide for the locking-bolt g. One
end of the said locking-bolt passes through
perforation f' of the nose f, while the other
40 passes through a perforation fi in the sash
and into a perforation f in the window-jamb.
Said bolt has cut on it near its center threads
h. The perforation in the bolt-handle I is
provided with threads, and said handle is
45 screwed onto the threads h of .the bolt g, so
that said bolt may be adjusted to pass through
any sash whether it be narrow or wide, and
have sufficient length to enter the perforation
f3 in the jamb. The bolt-arm I is provided
50o with another perforation j, to receive one end
of a coil-spring K. Said coil-spring is coiledaround the said bolt, and its other end passes
through the perforation fsin the nose f.
These ends turn down, so that said spring is
securely held in place. The tension of the 55
spring is such that the handle I is held down
by it in either one of the cross-slots c. It will
be seen that these cross-slots extend both
above and below the longitudinal slot b, so
that if it should be necessary to put the lock 60
on the left-hand rail of the sash the said han-
dle could still work in the then lower ends of
said slots, and the tension of the spring K
could be easily changed so as to draw the said
handle into said slots. The purpose of slot c 65
at the inner end of slot b is to hold the bolt g
by means of the arm I out of the perforation f5
in the window-jamb when it is desired to raise
or lower the sash, and this is especially im-
portant when this lock is used on sashes hung 70
on weights, as it would be very annoying to
have the bolt g jumping into the perforations
f5 as the sash moved up or down; but it will
be seen that by this method bolt g is entirely
out of the way when so locked back. The 75
other slot c at the other end of the slot b is
for an additional way of holding said bolt into
the perforations fi in the jamb, spring K also
helping to hold said bolt in place. The said
plate is also provided with wings 1, which are 8o
turned back, forming a half-hollow cylinder.
The purpose of this cylinder is more for ap-
pearance than any actual service, because
when the lock is put on the rail of the sash,
as shown in Fig. 1, part of it will be seen 85
through the glass from the outside, and the
cylinder can be made ornamental and would
look much neater than the lock would with-
out it; but I do not always put the lock on as
shown in Fig. 1; but I sometimes cut a recess 90
in the rail of the sash and set said lock in said
recess so that its inner end will be flush with
the inner edge of said rail and its lugs d will
be flush with the face of said rail, in which
case I make an additional perforation f4 in 95
the nose f, for the purpose of securing said
nose to the edge of the sash-rail.
As a modification of my lock I sometimes
cast or otherwise make the bolt g and arm I
in one piece and use the spring K without Too
passing it through any perforations j or f3, as
shown in the drawings.
