JOHN D. MILLER, OF SAN ANTONIO, TEXAS.
SASH-LOCK.
SPECIFICATION forming part of Letters Patent No. 7.31,317, dated June 16, 1903.
Application filed September 16, 1902, Serial No, 123,646, (No model.)To adl. whom it may concern:
Be it known that I, JoHN D. MILLER, a citi-
zen of the United States, residing at San An-.
tonio, in the. county of Bexar and State of
5 Texas, have invented a new and useful Sash-
Lock, of which the following is a specification.I
This invention is an improvement in sash-
locks or fasteners. Its object is the produc-
tion of a simple device easily applied and
10 operated whereby two sashes in a window-
frame may be controlled by a single means;
and it consists in certain new and useful fea-
tures of construction and in the combination
of the parts, as hereinafter shown, described,
15 and particularly pointed out in the claim.
In the drawings hereto annexed, Figure 1 is
a transverse horizontal section through a win-
dow frame and sashes at the meeting-rails.
Fig. 2 is a view showing a portion of the sashes
20 in elevation and a portion of the frame, sash,
and lock in vertical section. Fig. 3 is a plan
view of the device, the top plate or retain-
ing-cover having been removed. Fig. 4 is a
perspective view of the under side of said re-
25 taining-cover; and Fig. 5 is an elevation of
the device along the plane indicated by the
line V V in Fig. 2, the casing being shown in
. section and-the interior mechanism in trans-
verse elevation.
30 This sash-lock may be applied wherever two
sliding sashes serve to close a window-frame.
It is adapted for location opposite the sash
meeting-rails, and by its use both the sashes
. may be locked or supported by one device
35 and only one of them released at a time.
In the drawings, 10 indicates a portion of.
one side of a window-frame; 11, the upper
sash; 12, the lower sash; 13, the outside bead;
14, the parting-bead; 15, the inside bead, and
4o 16 a portion of the casing of an ordinary win-
dow.
Inserted in a suitable cavity in the frame
10, opposite the..meeting-rails of the sashes,
is a rectangular metal casing 17, having a de-
45 tachable cover 18, which is secured in place
in any suitable manner, as by a screw 19 en-
gaging a socket 20 in the bottom of the casing.
Yieldably supported in the casing 17 and
passing through the cover 18 are bolts 21 22,
50 adapted to respectively engage spaced cavi-
ties in the adjacent edges of the sash 11 12.These bolts 21 22 are provided, respectively,
with springs 23 24, by which they are main-
tained normally in engagement with the sash
and adapted to be withdrawn into the casing 55
17 when the sash is to be released. The sashes
11 and 12 are provided with spaced recesses
25 26, adapted for engagement with the bolts
21 22, said recesses being plainly seen in Fig.
2 of the drawings. Longitudinally disposed 6o
centrally through the casing is an operating-
rod 27, extending outward at one end through
the frame 10 and casing 16 and provided
with a knob 28 upon its outer end, by which
means the rod may be operated from inside 65
the room.
The casing 17 is provided with a transverse
partition composed of webs or fins 29 and 30,
rising from the bottom and depending from
the cover of said casing. One end of the cas- 70
ing is likewise formed by a flange 29a, rising
from the bottom of the casing, and a web 30a,
depending from the cover. This end and the
transverse partition are provided with bear-
ings for the rod 27, which has a longitudi- 75
nally-slidabie and also a rotary movement in
said bearings. A spring 32 is coiled upon
the rod 27 between the partition 29 30 and an
arm 36, extending laterally from said rod,
which is thereby forced in an outward direc-. 8o
tion, and the arm 36 by engaging the bolt 22
limits the outward movement of said rod.
The bolt 22 is provided with a laterally-ex-
tending arm 34, upon which the pin 36 of the
rod normally rests. The rod 27is provided at 85
its inner end with a laterally-extending pin 37,
adapted to engage an arm 33, extending lat-
erally from the bolt 21.
It will be seen that when the rod 27 is in its
normal position it may be partly rotated,with 90
the effect of depressing or withdrawing from
engagement with the recesses 26 in the lower
sash the bolt 22, thus permitting said sash to
be manipulated. Similarly, by pressing the
rod 27 inward against the tension of the 95
spring 32 a partial rotation will cause the pin
37 to engage the arm 33 of the bolt 21, with
the effect of withdrawing the.latter from en-
gagement with the upper sash, which may
thus be manipulated at will. A cam 35 is zoo
formed in the bottom of the casing, which by
engaging the pin 36 guides the latter to.itsNo. 731,317.
