Another purpose is to provide such a structure
in which the outside handle can be locked either
from outside the car or from the inside of the
car, and yet which will permit the latch bar
to still be operated from the inside of the car.
Another object is to provide a structure in
which, the outside handle is arranged in a coun
tersink in the door, so it will not catch on cloth
ing.
A further object is to provide a number of
improved details in structure of a latch and lock
mechanism.
.
- With these and other objects in view, my in
vention consists in the construction, arrange
ment and combination of the various parts of
my door latch and lock structure, whereby the
30
objects’contemplated are attained as herein
after more fully set forth, pointed out in my
claims and illustrated in the accompanying
drawing, in which:
'
_
Figure 1 is a horizontal, sectional view ofa
tip 20 is extended. The latch tip 20 has the or
dinary latch bolt 2|, which near its end farthest
from the latch tip 20 slides through a yoke 22
on the plate l1.
.
From now on, I shall describe the structure
as though the plate I‘! were in its vertical posi
tion as installed as illustrated for instance in
Figure 1, and shall treat that face of it ‘which
is toward the outside of the car as its outer face.
Extending outwardly from this outer face is an
upper angle bracket 23. Similarly extending out
wardly from the outer face of the plate I‘! is a
lower angle bracket 24, the outer end of which
as indicated at 25 in Figure 2 is offset slightly to
ward the bracket 23. This offset is merely for
the purpose of affording proper clearance for the
various parts.
The latch bolt 2| rests just above the bracket
24, as perhaps best illustrated in Figure 4, and
may even slide thereon. The latch bolt, 2| as
shown in Figure 6 has an outwardly projecting
portion of a car door equipped with a latch and ' arm 26.

I provide a handle which is indicated general

Figure 3 is a detail, sectional-view taken on the
line 3-2 of Figure 1.

Figure 4 is a detail, sectional view taken on
the line 4-4 of Figure 1.
_ ‘
Figure 5 is a view similar to, that of Figure 4
illustrating the parts in another position; and
Figure 6 is a detail, sectional view taken on
. the line 6—6 of Figure 2.
In the accompanying drawing, I have used the
reference character A to indicate generally an
automobile door or the like and the character
B to indicate the body of the car. Since most
pleasure cars are now made‘ of metal, I have
shown that type of structure in my drawing.
The door A has the inner wall "I and the
outer wall I! connected by the closure wall I!
at the edge of the door.
Similarly the car body B has theinner wall
55
ly at C, and which is in the‘ form of a bell crank
lever, with the handle portion 21 and the arm
portion 28.
The handle C is pivoted on a pintle or the
like 29 between the outer ends of the brackets
22 and 24 with the arm 28 projecting generally
in'the direction of the plate I‘! and the handle
portion 21 projecting generally to the right from
the pintle 29 when the parts arein the position
shown in Figure 1.
a
i
It should be mentioned perhaps that the wall
vl2 is provided with an indentation or counter
sink ” which receives the handle 21 when the
latter is in its normal position. The handle is
tensioned toward this normal ‘position by means
of a spring 3|, which has a coil mounted on the
pintle 29 and one am engaged with the bracket
24 and the other arm engaged with the arm 20
(see Figures 1, 2 and 3).
The handle 21 can be pulled from its normal
45

full line position shown in Figure 1, when it is
substantially received within the recess 38 out
wardly to its dotted line position shown in Fig
ure 1.
This swings the arm 28 to the right to
its dotted line position shown in Figure 1.
In the inner part of the arm 28 is mounted a
slidable bolt 33 actuated by a locking mechanism
34 of any di?erential type. The slidable bolt 33
when in its retracted position stands just to the
left of the arm 28 on the latch bolt 2| when the
latter is in locking position.
The latch tip 20 and latch bolt 2| are spring
pressed toward locking position by means of a
spring 35.
'
~ The bracket 24 has a hole 36 in line with the.
15
slidable bolt 33, and by actuating the lock mecha
nism 34 and sliding the bolt 33 from its position
shown for instance in Figure 4 to its position
shown in Figure 5, the end of the slidable bolt 33
20 may be projected through the hole 36, whereupon
the handle can not be actuated.
On the other hand, when the slidable bolt 33
is in its retracted position, illustrated in Figure 4
and in Figure 3, the swinging movement of the
25 handle 21 from its full line position shown'in
Figure 1 to its dotted line position shown in
that ?gure, causes the slidable bolt 33 to engage
the arm 26 (see Figures 3, 4 and6) for-retracting
the latch tip 20 and latch bolt 2| for unlocking
30
the door.
,
’
The spring 3| tends to return the handle to its
normal position whenever the grasp of the oper
ator is released, and the spring 35 then serves to
return latch and latch bar to locking position.
Connected to the latch bolt 2| is a link 38 shown
36
for instance in Figures 1 and 2. This link has an
elongated slot 39 slidably mounted on a pin 48
on the latch bolt 2|. It is intended to be con
nected with any door opening structure oper
40 able fromthe inside of the car, which structure
is not here of any special importance.
On account of the fact that the pin 40 slides
in the slot 39, the mechanism here shown may be
45
outwardly from its position shown in Figure 1
for instance to its dotted line position in that
?gure will be resisted by engagement of the arm
28 with the ?ange 45 (see Figures 1 and 4).
The locking member F may be manually oper
ated by means of. a pin 48 secured to the plate
43 and extending through a curved slot ,43 in the
plate I‘! and through a suitable slot 58 in the
inner wall In of the door, and having on its outer
end the head 8|. The material around the slot 50 10
is arranged to coact with a spring 52 on the pin
48, so that the pin will be frictionally held in any
position to which it may be adjusted.
When the latch member F is thus manually
operated to any position, it can, of course, be 15
manually operated from the inside of the ear to
any other position.
It will be noted that regardless of the position
of the latch member F, the latch tip 23 and latch
bolt 2| can be freely operated by means of the 20
link 38.
Thus the door can be unlatched from
inside at any time.

Ii’, however. the latch member F has been
moved to locking position, and it is desired to
unlock the door from the outside, the key is 25
turned in the lock‘device 34 and the bolt 33 is
?rst moved to its extended position shown in '
Figure 5 for engaging the ?nger 41 and moving
the member F to unlatching position, and is then
retracted, whereupon the, handle 21 can be freely 30'
operated for opening the door.
If it is desired to lock the door from the out
side, the key is turned to position for movingthe
bolt 33 into the opening 36 and the parts are
then left in this position. It is then impossible to 35
open the door from‘ the outside. The projection
of the bolt 33 through the opening 38 looks the
arm 28 and the handle 21 against door unlatching
movements The door can not then be unlocked
from outside without using a key for retracting 40
the bolt 33.
It will thus be seen that I have provided a

rather simple lock structure, providing for the
arrangement of the handle 21 normally in posi
mechanism 34 is not shown in detail and any
suitable mechanism might be employed for mov
the garments of those who get into and out of
ing the slidable bolt 33 lengthwise.- As here
.shown, the cylinder of the locking mechanism 34,
is mounted to rotate and has on its inner end an
off-center pin 4|, extending lengthwise of the
50 cylinder and at right angles to the slidable bolt
33.
The slidable bolt 33 has a groove 42 into which
the pin 4| projects. These parts are so arranged
55 that when the cylinder of the lock 34 is rotated,
the slidable bolt 33 will be moved lengthwise.
I have also provided a separate means for look
ing the latch from the inside of the car. This
is of peculiar shape and is shown at F for in
60 stance in Figure 4. It consists of a plate portion
43 pivoted at 44 on the plate ‘l1. Projecting from
one edge of the plate portion 43 is a ?ange 45.
Projecting downwardly from one end of the ?ange
45 at the outer edge thereof is a hook-like mem
tion in the recess 38, where it will not catch on 45
the car.

The door can be unlatched and opened by
pulling the handle 21 outwardly to the dotted
line position shown in Figure 1 .for unlatching, 50
and then ‘continuing the pull for swinging the
door open.
.
'
When the bolt 33 of the lock is retracted, it
will coact with the arm 28 for unlatching the
door, and when the parts are in-proper position, 65
and it is projected through the hole 38, the han
dle mechanism can not be worked. Yet even
then the latch bolt 2| can be operated from the
inside 0! the car.
The structure is such that the latch member
