Improvements in Locks and Latches.
I, BYRON PHELPS, Inventor, of Seattle, State of Washington, United States
of America, 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:-
My invention relates to the class of locks, and my object is to provide a lock
which may be inserted in a notch in the stile of a door. In the embodiment of my
invention shown in the drawings.
Fig. 1 represents a side view of my lock, parts thereof being in section on
the line WX of Fig. 2.
Fig. 2 represents a plan view of Fig. 1 on the line Y-Z.
Fig. 3 represents a back view, showing parts broken away and other parts
in section, of the lock represented in Figs. 1 and 2.
Fig. 4 represents a detail of one side plate.
Fig. 5 represents a stile of a door having a notch into which my lock is adapted
to be inserted.
Fig. 6 represents a rear view of a modification of my device.
Fig. 7 shows a side elevation, and
Fig. 8 a front elevation of my lock in position as applied to the stile of the
door.
Figs. 9, 10 and 11 show details.
In the construction shown in the drawings I have provided a main frame to
support the mechanism. This main frame has a side C³, and preferably an
opposite side (5, in this embodiment formed by two portions 24, 24, with suitable
connections joining the sides. The main frame also embraces two hollow spindle
bearings dd extending transversely outside of the same and preferably formed
integral therewith. These spindle bearings are separated from each other;
that is, there is a space between the same through which certain parts of the
lock may project such as, in this embodiment, the follower or roll back C¹ is an
escutcheon plate surrounding the bearing and may be integral with that side
of the frame, but applicant does not limit himself to a construction in which the
escutcheon plate is integral with the frame or with the bearing, because it is
obvious that many changes may be made in the construction herein disclosed
without departing from the spirit of my invention. In the present embodiment
this plate is applied directly to and is integral with the side C and helps form
one side of the frame carrying the bearing d. 22 is a connection between
the spindle bearing d and one side of the frame. The frame preferably has a
face plate C3 projecting laterally from one side thereof, in this embodiment
extending clear across the front end of the frame and having an opening therein
for the latch bolt, as shown. This face plate is preferably formed by the front
end of the frame itself being integral with the frame, but it may obviously
consist of a plate separate from the frame if desired.
C is a second side plate having a hole therein by means of which it may be
lipped over the spindle bearing d. This side plate has a projection 20 having

page_text: '
lips 21 to embrace the face-plate C³, and these two side plates C and (may be
adjusted relatively to each other by the screws 3, 3, to fit doors of different
thicknesses, all as clearly shown in Figs. 7 and 8.
The latch mechanism embraces a latch bolt or head I pivoted between lugs k
by the pins i. The latch bolt projects through the opening in the face plate C³.
H is a shoe formed in this embodiment of a slide H and yoke H. This slide H
is pivotally attached to the bolt I by the pins and has a slot therein having
an enlarged aperture 3. The yoke H¹ has a T-shaped head h¹ which may be
inserted through the aperture ³ and slipped down to the position shown in
Figs. 1 and 2, where it will be held from disengagement by reason of the slot h³
being narrower than the head h. The yoke H has preferably two legs as shown
each one of which has a projection h. The ends of springs 1 and 2 coiled around
pin press on H and H¹ respectively to throw them, and so the bolt I, forward.
The spindle bearings d and d' are separated, and between them is a sleeve G
carrying bolt actuating means consisting, in this embodiment, of a double
follower 9 g which contacts with projections h h on shoe H².
l
From the sleeve G project outwardly spindles E E, in this embodiment con-
nected together as shown in Fig. 9. These projections on either side of the
sleeve G may each be denominated a spindle, as by the rotation of either of them.
the latch bolt may be withdrawn as hereafter explained. These spindles are
preferably chambered, as shown, and in the shaft formed by said two spindles
are three slots as shown in Fig. 9. In one of said extensions or spindles E¹ is
a longitudinal slot e as shown in Figs. 2, 3 and 9, and a second longitudinal
slot 12. Within this chambered spindle E extends locking means to lock the
opposite spindle E, and in this embodiment also spindle E', from rotation,
consisting of a lock rod M having a projection 6 passing through slot e and a
second projection 7 passing through slot 12. The position of the slots with
relation to the other parts is shown in Fig. 3 by dotted lines.
13 is a slot in the sleeve G, and 9 is a slot in the frame, which slots register
when the sleeve and rollback are in their normal position of rest.
The pro-
jection 7 passes through the slot in the sleeve G as shown in Fig. 3. but on
account of the longitudinal slot 12 may be moved out of this slot 13 in the
sleeve, thus disconnecting the sleeve and rollback from the spindle, into slot 9
which will lock the spindle E, and in this embodiment spindle E also, from
rotation. This longitudinal movement of pin 7 may be accomplished by a finger
piece K extending transversely outside the spindle and carrying cam faces
formed by the sides of the inclined slot K¹ therein, in which slot the projection_6
moves. By the rotation of the finger piece K the projection 6 and consequently
the lock rod M and projection 7 will be moved longitudinally of the spindle.
10 is a sleeve covering the cam and pin to conceal the same, and F is a knob
having a shank of which abuts against the slotted sleeved part of finger piece K
and holds it between itself and the bearing d, as shown clearly in Fig. 3, 11 is
a transverse slot in spindle E through which projects a pin 8 on a key rod L
within said spindle, and said projection 8 also passes through and fits a hole in
sleeve G, as shown in Fig. 3. E is a longitudinal hole in the end of spindle E 4
through which a key is adapted to be inserted to engage the end of key rod L to
rotate the same. It will be obvious that when the finger piece K has been
rotated so as to bring the projection 7 into the slot 9 and lock the spindle E
from rotation, a key may be inserted in a hole E and the key rod L rotated
within the fixed spindle. The sleeve G and follower g g will thus be moved as 5
pin 8 tits the hole in said sleeve, and the latch will be thrown back without dis-
turbing the locked spindle E.
P is a strike plate having the usual aperture therein over which is a hood 30.
This strike plate preferably has a projection or wing 31 standing substantially
perpendicular to the face of said plate, as shown in Figs. 1 and 2. The side 5
plate C is preferably set back on the frame as shown in Fig. 2, so that this
wing 31 will project along the side of the frame to aid in forming the jamb of

page_text: the door when the door is closed as shown. The hood and wing 31 prevent
tampering with the bolt from outside the door.
It will be seen that by my construction I provide an extremely simple lock
which may be completely assembled for shipment, and yet may be applied in
position in the stile of the door without disassembling any of the parts. It is
applicable to either a right-hand or left-hand door by merely reversing its position
and may be inserted in a notch in the stile of a door and securely clamped therein
by drawing the side plates toward each other. The latch is always movable
whether either spindle is locked or not and the construction of the lock and
hooded strike plate prevents unlawful tampering with the latch bolt. The face
plate C allows for different adjustments of the side plates relatively to each
other and consequently one lock may be applicable to several thicknesses of doors
and yet the notch in the door will be entirely covered and no slot will be left,
although the same lock is applied to stiles of differing thickness. This dispenses
with the necessity of a different lock for each thickness of stile. A latch bolt
having a breadth nearly as great as the thickness of the stile of the door can be
used as nearly the whole distance between the side plates can be utilized, which
is a distinct advantage over the usual style of locks. Considering the construction
as shown in Fig. 3, the right-hand spindle might be on the inside of a door
and the left-hand spindle upon the outside. By mere rotation of the finger
piece the door will be securely locked from entrance from the outside, but
by the insertion of a proper key into said spindle the latch may be thrown back
without interfering with the locked spindle.
In Fig. 6 I show a modification of my device in which each spindle has a rod
corresponding to the rod M and also a finger piece, so that by the rotation of
either finger piece the opposite spindle will be fixed and consequently the door
cannot be opened by the rotation of said opposite spindle. This modification is
particularly applicable for doors between connecting rooms.
It is obvious that many modifications of my device may be made without
departing from the spirit of my invention..

tion and in what manner the same is to be performed, I declare that what I
