The lock includes a housing or casing I formed
of a horizontal top wall: 2., a horizontal bottom
wall 3, a vertical front wall li, a vertical rear wall
5fand a vertical inner end- wall G. The housing 20
I- is open at itsouter end.
The Walls 2, 3, 5 and
6» are integralv with each other.
The wall d is
positioned against the edges of and is suitably
connected with the walls 2, 3, 5 and 6. The
height of the~walls 4', 5 is materially greater than 25
the width of the other of. said walls.
Positioned against the open end of housing I
is a combined closure and guide plate l' which
corresponds in width. to that of the housing I and
is of a length to extend above the wall' 2 and to 30
depend from the Wal1.3'. The plate 'I, as shown,
acts as a closure for the open end of and also
as a means for retaining housing I‘ in pocket S'
formed` in a door 9. The extended end terminal
portions of plate 'I are to be mortised in the outer 35
side edge of the door il-` and are to be secured to
the latter by the holdfast devices, not shown,
which are to be extended through the counter
sunk openings Ißíformed in the plate. The latter
also functions as a combined support and guide
common to a latching member II and a locking
bolt or member I2, to be referred to and for
such purpose plate l is formed with an upper
guide opening I3: for the passage of member II
45
and a lower guidev opening I4 for bolt I2.
The walls 4, 5 between the vertical median of
housing I andv wall 6 are formed with aligning
openings I5, I5 respectively. The openings I5,
I6 are located between the longitudinal median
of housing I and~ wall 2. The door 9 is to be 50
providedwith a pair of aligned openings Il, I8
which align with the openings I5, I6 respectively.
The door 9 has secured thereto, at opposite sides
thereof, oppositely disposed bearing members I9,
20 formed with axial openings 2l, 22 respectively

2,124,099
aligning with the openings I1, I8 respectively.
Each bearing member is formed with an out
wardly directed annular boss 23 having its inner
face ñush with the edge of the axial opening in
the member.
The purpose of the aligned open
The carrier 4I consists of a shaft 41 having a
cylindrical intermediate portion 48, and a pair
of reduced squared end portions 49, 59.
The
ings I5, I6, I1, I8, 2| and 22 will be referred to.
Integral with the inner face of wall 5 is a flat
portion 48 slidably extends through the aligned
rectangular supporting lug 24 disposed in trans
opening 44 of head part 42 of element 49. The
latter is ñxedly secured to shaft portion 48 cen
trally of the latter. The reduced end portions 10
49, 59 provide shaft 41 with a pair of peripheral
shoulders 5I, 52 against which abutment discs
53, 54 respectively are positioned. Secured upon
verse relation with respect to housing I and
10 formed at its free end with a socket 25 for the
reception of a holdiast means, not shown, which
is to extend through the wall 4. The length of
lug 24 is such as to extend from the inner face of
wall 5 to the inner face of wall 4. The lug 24 is
of rectangular cross section and has its upper face
disposed at the longitudinal median of housing I.
The lug 24 is arranged between the vertical me
dian and open end of housing I and constitutes a
combined support and guide for latching mem
ber II.
Integral with the inner face of wall 5 is a flat
rectangular supporting lug 29 disposed trans
versely of housing I. The lug 29 is arranged
below, aligns with and is spaced from the lug 24
and constitutes a combined support and guide
for the member I2. The lug 24 further func
tions to arrest the bodily shifting upwardly of
and for retaining member I2 on lug 29. The
member I2 slides between the lugs 24 and 29.
30
part 43 is of less width and of less length than
the width and length of the part 42.
The latching member II comprises a relatively
short substantially rectangular bar-like body 39
having its outer end edge beveled as at 3|. The
body 39 is so constructed as to permit of its being
disposed for use on either one of its lengthwise
faces A or B. The side edges of body 39 are
indicated at C, D. As shown body 39 is disposed
on its face B. Integral with the face A of body
39 between the transverse median and outer end
of the latter is a square lug 32 having its outer
40 side face 32€l ilush with the side edge D of body
39.
Integral with the face B of body 36 between
its transverse median and outer end of the latter
is a square lug 33 having its outer side face 33a
flush with the side edge C of body 39. 'I'he body
39 in its faces A, B is formed with diagonal
grooves. The grooves are indicated at 34, 35 and
are of like form and align with each other. The
side walls of each of the grooves are indicated at
36, 31 and disposed in parallel inclined plates.
50 The grooves 34, 35 are arranged between the
transverse median and inner end of body 39. The
distance between the outer ends of the grooves
and the inner end of the body 30 is greater than
the distance between the inner ends of the grooves
and the inner end of body 39.
Secured to the inner face of wall 6, as at 33,
is an upstanding forwardly directed curved leaf
spring 39 which permanently bears against the
inner end 39a of body 39. The spring 39 acts to
60 normally maintain member II in latching posi
tion.
The member II is moved to released or
non-latching position against the action of
spring 39.
The lock includes a shifting device for sliding
member II from latching to non-latching posi
tion.
The said device consists of a vertically dis
posed actuating element 40 for and disposed at
right angles to member II and a horizontally
disposed slidable carrier 4I for element 49. The
latter is formed of a rectangular head part or
upper 42 and a frusto-tapered lower part 43 for
actuating the member II. The head part 42 is
formed with an opening 44 and has each side
vertically grooved as at 45, 46. The part 43 is
integral with the bottom edge of part 42. The
openings I5, I6, I1, I8, 22, 23 and also through
the reduced end portions 49, 59 of shaft 41 are
inner and outer socketed knobs 55, 56 respec
tively which clamp the discs 53, 54 against the
shoulders 5I, 52.
Engaging in one of the grooves 45, 46, as
shown, the groove 45, is the rear free end of a
flat controlling spring 51 for the slidable carrier. 20
The forward end of spring 51 is anchored against
a spacing collar 58 which is fixedly secured
against the inner face of wall 5 by the holdfast
means 59.
The lower part 43 of element 49 has its sides 25
oppositely beveled as at 69, 6I. One of said sides
is for the purpose of riding against the wall 31
of one of the grooves 34 and with the inclination
of such side being the same as that of the Wall
31. As shown the side 6I of part 43 is positioned
against the wall 31 of groove 34. The construc
tion of the element 49 and member I I permits of
reversing them when desired. 'I'he disc 54 abuts
one of the bosses 23 when the carrier is in inac
tive position and the disc 53 is to abut the other
boss 2S when the carrier is shifted to active posi
tion. The normal position of the carrier is as
shown in Figure 2 and is maintained in such
position by the spring 51. The carrier is moved
to active position against the action of spring 51. 40
The normal position of the element 49 is as
shown in Figure 2 with a beveled side of part 43
positioned against the end portion of a side Wall
of a groove in member II.
By pushing the car
rier outwardly from the inner side of the door
the head element 49 will act on the member II
and move it from latching to non-latching posi
tion. By pulling the carrier outwardly, the head
element 49 will also provide for the shifting of
member I I to non-latching position. The slid
able coaction of a beveled side of the actuating
element 49 with the rear wall of a groove in the
member II, as the carrier is slid or pulled out
wardly provides for the action as aforesaid.
The locking member I2 comprises a rectangu
lar bar 62 disposed on its lower lengthwise edge
and formed in proximity to its rear end with an
enlarged groove 63 opening at the lower edge
thereof. The groove 63 has a pair of straight
side walls 64 and an arcuate top wall 65. Ar 60
ranged in the groove 63 is a cam 66 formed
eccentrically of its sides with stub shafts 61, 68
which are journaled in openings 69, 19 formed in
the walls 4, 5 respectively. The cam 66 eccentri
cally thereof is formed with a socket 1I ln the
65
form of a die simulating a letter of the alphabet,
or a number; as shown it is a letter.
The walls 4, 5 are provided with openings, not
shown for the insertion of a key, not shown,
formed to conform to the contour of the socket
to enter the latter for the purpose of rotating the
cam in a direction to shift member I2 from the
position shown in Figure '7 to locking position as
shown in Figure l.
The member I2 intermediate its ends and on
2,124Qo99
its upper face has formed integral therewith a
square lug 'I2 which functions respectively for
limiting the extent of the shifting of member I2
to non-locking position; to arrest the moving of
member II to non-locking position when the
member I2 is in locking position; and for limit
ing the extent of the shifting of member II to
non-latching position when member I2 is in
