5 Claims. (Cl. 296-44)
‘This invention relates to that class of safety
hinges and hinge assemblies that are especially
adapted for use on doors for automobiles, buses,
trucks, railroad cars and the like.
This invention has a further applicability for
doors requiring safety in the manner of ?nger
pinching, especially that of children and inmates
in hospitals, nursery rooms and such like.
These ends were also the object of my earlier
10 invention‘in this art, Patent No. 1,986,496 Jan.
1, 1935 to which the present invention is a con-/_
tinuation and constitutes an improvement over
my prior invention.
The improvement iswdirected especially to pro
15 vide a hinge assembly for a car door devoid of
any outer projection whether said door'is open
or closedand thereby greatly improving the, ap
pearance of an automobile and such like. The
‘hinge assembly aforesaid maintains the , same
bottom sections of the hinge assembly of one of
the doors of the car showing the thrust bearing .
'and also the bearing assembly.
Fig. 3 is a view taken on a line 3,—3 of Fig. 2.
Fig. 4 is a section taken on a line 4-4 of Fig. 2. .5
Fig. 5 is a section taken on a line 5—5 of Fig. 2._
Fig. 6 shows a section of a modi?cation of the
hinge assembly with respectto the hinge con
struction shown in Figs. 1 to 5 inclusive.
Fig. 7 is a section taken on a line 1-1 of Fig. 6. l0
In'this ?gure the car door is in closed position.
Figure 8 shows the same door shown in Fig. '7
in an open position.
Referring to Figs. 2 and '3, the numeralv Ill
represents one of the doors of an automobile 15
body. . The door proper is made in the usual i
mannerv and consists of an outer sheet metal
shell II and an inner combination wooden frame
and fabric lining l2.
Anupper casting or forging l3 and a lower 20
20 'space relation between the outside section of the
door and the outside section of the body of said ' casting or forging H are each, spot welded,
vautomobile no matter whethersaid door is shut
or opened at any angle in which the aforesaid
door ‘is moved. '
A further object is to provide a hinge assembly
for an automobile door that will be free from
sag and will provide adequate safety from ?nger
pinching in so far as thehinge assembly is con
cerned, both at the inside as well .as the outside
of the automobile aforesaid.
A further object is to provide a hinge assembly
that can be incorporated‘ with and made part
of the car body in the fabrication thereof; and
screwed or riveted to the outer shell ll, of the
door 9.
(See Fig. 3.)
The said forgings I3 and H are provided with
borings or the like I5 and i6. Inside each ibOr- 25
ing there is ?tted a hinge pin' II which consists
of two parts l8-and l9. Part I8 is provided with
a series of grooves 20 cut around the circum
ference of said part. The function of said grooves
will be explained hereinafter.
'As already stated, part 19 of the hinge pin
I1 is somewhat smaller in circumference than
part l8 and said part ?ts inside a bearing. 2|

The casting 29 is secured to the body of the door

,The casting‘ 30 is likewise secured to the body of
the'car by means of the screws» 33.
In manufacturing the body of the car involving
the hinge assembly as described, the forgings 23
and 24 are preferably spot welded to the body of
the car as shown in Fig. 1. The forgings l3 and
M are also preferably spot welded to the body of
'20 the door.
When the car body is ready to receive the ‘doors,
the bearings 2i and 22 are inserted into the forg
ings 23 and 24. Likewise hinge pins I‘! are insert
ed into the bearings l5 and Hi. The door is then
25 ready to be ?tted into the door opening of the
hinge projections.
the present invention, the hinge supports are fab- ,
ricated directly into said body. The larger pro
portion of the hinge assembly, however is incor
porated into the car door. .
. A screw driver orv like tool is inserted into the
threaded openings 21, and the pins H are forced
into the bearings 2| and 22 by means of said tool.
30 In this connection the circumferential grooves
20 are used as a pry for this purpose.
In actual manufacture of the car body with
When parts l9 of the hinge pin I‘! are ?rmly
seated into the bearings, the screws 25 and 26 are

A considerable amount of time can be saved in
mounting of the doors with the present invention
as compared with mounting of the doors upona
car body. with ordinary type hinges.
When it' is desired to remove the door, both top
and bottom screws 25 and 26 which are located
on the door are removed, and after said removal,
a screw driver or similar tool is inserted through
the threaded openings 21 and then‘ to pry by
means of said tool the hinge pins I‘! from off the
hinge bearings. After this has been accom
plished, the door is ready for removal. The re
verse procedure is performed to mount the door as
previously explained.
A further desirable feature is that the hing
ing section being curvilinear in construction con

‘ _ Referring to Figs. 4 and
1. In a hinge assembly of the class described
will be noticed that the hinge axis of the door supporting a door upon a door frame or the like; 50
50 is not locatedat or near the center of the top or said assembly comprising metalw sections fabri
lower edge of the door, but that the distance A, cated into said door, metal sections fabricated
from the inside wall of the car is greater than the into said door frame adjacent to and complemen
distance B to the outside wall of the car. The
tary‘to-said metal sections in said door; a bore
distance B is less than the radius C which the door or the like in each of said metal sections; the
describes when rotated on its hinges. Thus, when
axis of said bores ‘in said door metal sections
the door is closed, there is presented to view ex
being eccentric with respect to ,the top and bot
teriorly a narrow edge'D. This is in contrast with
the contour of the hinging section of the door in
a closed position as shown in my previous Patent
No. 1,986,496.
In mounting ordinary types of hinges on- auto
mobile doors', it is ,nece'ssary to provide a sub
stantial and sturdy stanchion support on the
' hinging side of the door opening in order to ade- -
quately support the hinge member that is screwed
_into_the side of said door opening. Usually as
many as six screws are required for each hinge
member which is screwed into the top and bottom
tom transverse edge of saidv door; hinge pins
affixed in said bores for joining and holding said
metal sections on said door frame with corre-_ 60
sponding metal sections on said door; and pin
securing means operable through the door face
for holding said hinge pins in- position.
