2 Claims. (G1. 16-86)
This invention. relates to door stops and more
particularly to a door stop constructed to con
stitute a conduit through which electric wires,
pipes, cables and the like may be carried for the
5 purpose of performing various operations in a
door without interfering with the opening and
closing thereof.
In Patent 2,082,449 of June 1, 1937, I have
disclosed door stops through which electric wires
10 are extended for the purpose of operating the
locks of three of the doors of an automobile
from a switch associated with the fourth or mas
ter door.
While the door stop of the present invention
is primarily intended for use in multiple lock
sets, it is none the less true that it is capable
of use in many other relations and, in fact, in
any relation wherein it is desired to carry power
wires, pipes, or cables between two hingedly con
nected elements.
In the accompanying drawing‘:
Fig. 1 is a perspective view of a door stop
constructed in accordance with the invention;
Fig. 2 is a horizontal sectional view of the same,
Fig. 3 is a vertical sectional view showing the
device applied to the door and ‘body of an auto
Like numerals designate corresponding parts in
all of the ?gures of the drawing.
Referring to the drawing, 5 designates a curved,
tubular member, extended at one end to form
the vertical, ‘tubular, 'T-head extension 6. The
outer end of the member ‘5 is preferably thread
ed for reception of a nut ‘I, and a rubber, ?bre
or other cushioning washer 8 lies inwardly of
the nut l. The vertical extensions of the ‘T, the
shank of which is represented by the curved tube
5, is journaled, i. e., pivotally mounted in the
horizontal ears 9 and Ill of a supporting plate H.
The plate H is secured by bolts 12 or like
fastening devices to the inner side frame mem
‘ber of the car ‘body 13, and said plate has a
-'slot I4 to permit lateral swinging movement of
45 the tube 5. It is not essential that a wooden
frame member be employed in the car body,
but the plate H may be secured to the shell of
‘an all-steel body and the ears 9 and Ii] merely
‘project inwardly of said body.
A ?bre or rubber cushioning disk or bushing
I5 is preferably secured to the inner side of the
side frame member of the door to constitute an
abutment for the washer 8, in the cushioning of
the opening movement of the door and a guide 5
for tube or shank 5.
As previously stated, this door stop is of gen
eral application. It is not even restricted to
the passage of electric wires ther-ethrough, but
upon the contrary might accommodate a flexi- 1o
ble tube, such as a rubber hose, through which
a pressure ?uid could be carried for the pur~
pose of operating the locks or performing other
functions by hydraulic power. The same is true
with respect to- pipes for conducting compressed
Therefore, it is to be understood that the
invention is not limited to the precise construc
tion set forth, but that it includes within its pur
view whatever changes fairly come within either
the terms or the spirit of the appended claims.
Having described my invention, what I claim
1. A door stop- comprising a T-shaped, tubu
lar member, a stop element upon the shank of
theiT-shaped member, a supporting element com~
prising a vertical securing plate and horizontally
disposed spaced ears integral with said plate and
within which ears the head of the T-shaped tu
bular member is journalecl to- turn, said plate
being laterally slotted and the said shank pass
ing through the slot of said plate, whereby an
electrical conductor may pass through the shank
and through the tubular head, as and for the
purposes set forth.
2‘. A door stop comprising a T-shaped, tubu
lar-member, the bore of which is continuous from
the outer end of the shank of said member to
and through the head of said T-shaped member,
a .stop element upon the shank of the T-shaped
member, and a supporting element comprising a
pair of spaced plates within which the head of
the T-shaped member is journaled to turn about
an axis concentric with the bore of said tubular
head, whereby an electrical conductor may pass 45
longitudinally through the shank and axially out
through the bore of the tubular head, as and for
the purposes set forth.
