Improvements in Locks and Latches.
I, BYRON PHELPS, Inventor, of the City of Seattle, State of. Washington,
U.S.A., 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 locks, and my object is to improve the construction of
the same.
In the preferred embodiment of my invention shown in the drawings.
Fig. 1 represents a horizontal section through my lock.
Fig. 2 represents a section on the line 2-2 of Fig. 1 looking in the direction
of the arrow.
Fig. 3 represents a section on the line 3-3 of Fig. 1 looking in the direction
of the arrow, and
Figs. 4 and 5 represent details.
In the above preferred embodiment, A represents the frame of the lock, having
spindle bearings B and C. b and c are escutcheon plates. This lock is adapted
to be inserted in a notch in the stile of a door. Within the spindle bearings
are rotatable spindles D and E preferably normally connected so as to rotate
together, as shown. F is a latch bolt or head pivoted to the frame, and f is a
connecting means to this bolt preferably in the form of a yoke, as shown in
Fig. 5, having two arms to be engaged by the followers or roll-backs, so that
the bolt will be retracted by the rotation of a spindle in either direction. G is
a follower connected with the spindle D to contact with the yoke and actuate
the bolt. This follower is preferably located in, and held in place by, a slot g
in the spindle D, as shown in Fig. 4.
H is a finger piece, formed in this embodiment of a rotatable cup-shaped
portion and a cap therefor closing the same. This finger piece is preferably
located upon a reduced portion of the spindle bearing. K is a knob carried on
the end of spindle E and attached thereto in any suitable way such as by a
pink Extending laterally of the spindle E is a projection k', in this embodiment
formed by a projection from knob K. The cap h is in this embodiment fixed
to the spindle bearing, but the cup-shaped portion is rotatable relatively to
said bearing. The cup portion and cap are held in place between projection k
and an abutment, formed in this embodiment by shoulder 2. I have provided
a means to lock spindle D from rotation and adapted to be operated by the
finger piece which is located on the side of said lock opposite said spindle D.
e is a slot in, and in this embodiment a hole through, spindle E, and c is a hole
registering therewith in bearing C. is a dog pivoted to cap ¹ by the pin 4,
and is a spring acting on a projection from said dog, as shown in Fig. 2 to
turn the same on its pivot. This dog has a lug adapted to pass from the
hole c in the spindle bearing into the hole e in the spindle to lock, in this embodi-
ment both spindles E and D from rotation. h is a pin carried by the rotatable
part of the finger piece. 7 and 8 are depressions in the face of said dog form-
ing cam faces, the bottoms of which depressions are at different radial distances

page_text: from the center of the finger piece, so that when said pin he is moved from the
one to the other, the dog will be turned, and consequently the lug h³ will be
moved laterally of said spindle and into or out of engagement therewith. Said
depressions also form a locking means for said finger piece as the pin will not
ride out of one into the other without slight pressure.
and
L is a slot preferably in the spindle D and preferably wider than slot
in this slot L is located a second follower L', which also engages the yoke f.
This slot L is preferably wide enough so that follower L' may be moved to draw.
back the bolt independently of spindle D or spindle E so that when said spindle D
is locked from rotation the follower L' might still be rotated and draw back the
bolt.
M is a knob carried on the end of the spindle D and preferably formed in two
parts held together by screws, as shown. Contained within this knob and fixed
relatively thereto so as to be movable therewith is a preferably pin tumbler
lock m having an inner part rotatable relatively to the lock casing, such as a
key barrel, as is common in this class of locks. m¹ is a reduced portion of this
pin tumbler lock casing and m² is a ring into which said reduced portion fits
and m³ is a depression in the knob in which said ring may be located. m² is a
projection on the end of the rotatable key barrel over which fits a hollowed
cap N. This cap has a hole therein preferably angular and passed through and
fitting this hole is a preferably angular rod n, having a head n¹ thereon contained
within said hollowed cap. The cap is fixed to the projection m by a pin n², as
shown. This rod, which I designate a key rod, passes inward from the cap N
loosely through a round hole in follower G, as shown in Fig. 5, so that said
follower will not be actuated thereby when said rod is rotated: This rod then
connects directly with follower L¹, passing into a hole in said follower which fits
said rod so that when said rod is rotated said follower L will be moved to draw
back the bolt.
When in this embodiment either knob K or knob M is rotated, the rollback G
will be moved and will contact with yoke f and draw back the bolt. When the
finger piece is rotated from the position shown in Fig. 2 in full lines to that
shown in dotted lines, the pin will drop into the depression 8 and the lug h5
will enter the hole e in the shaft E and lock spindle D, and, in this embodiment,
both spindles, from rotation. The knob M is thus locked from rotation, and
as said knob is intended to be upon the outer side of the door, the door is thus
securely locked from entrance from this side. A key, however, may be inserted
in the key barrel of the pin tumbler lock as is usual in such locks, and the key
barrel rotated while the knob M and spindle D still remain fixed. This rotation
of the key barrel will also rotate key rod and consequently rollback L' throw-
ing back the bolt, and yet the spindle D remains locked.
It will be obvious that very many changes may be made in the construction
herein disclosed without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of this said in-
vention and in what manner the same is to be performed, I declare that what I
claim is;-
