Improvements in Door Holders.
I, EDWARD LOUIS SCHACHT of Grand Avenue, Chicago, Illinois, U.S.A.,
Manufacturer, 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 :-
The device of this invention is shewn in the accompanying drawing,
Fig. 1 being a perspective of the same applied to a door and door frame, Fig. 2
a plan view of the same with the door and door frame in horizontal section and the
door held in a slightly opened position,
Fig. 3 a detail elevation illustrating the position which the links or arms of the
device assume when they are disconnected from the bracket or fixture on the
door,
Fig. 4 an enlarged perspective view of the door bracket removed and
Fig. 5 a detail horizontal section taken in a plane above the inner link or arm.
A is the door frame and B the door both of ordinary construction and only
shewn to illustrate the application of the device.
C is a bracket or fixture on the door and comprises a body plate a having holes 6 for
the reception of attaching screws c, a horizontal projection d and studs e, e², projecting
upwardly and downwardly respectively, from the projection d at its outer end, and
provided with heads preferably of the form shewn. These studs permit the
application of the device to either right or left hand doors the stud e being
designed for use when the bracket is applied to a left hand door and the stud e¹
when the bracket is applied to a right hand door.
D is a bracket fixed to the door frame and having holes 9 for the reception of
attaching screws h, also a central aperture i in which is journalled the trunnion j
of the arm E so as to be capable of turning therein. The trunnion is held in the
bracket plate by means of an enlargement at its inner end as shewn or by any
other suitable means.
F is the inner link of the device and G the outer link, the former pivotally
connected to the arm E and the latter to the outer end of the link F preferably by
rabetting the respective parts and joining them by rivets or pins k, l.
The outer link G is provided at its outer end with an aperture H for the
reception of the stude of the door bracket C and is shaped in conformity with
the head of said stud in order to permit the link G to be placed on and removed
from the stud when the door is in its closed position.
In using the device, the link G is connected to the door bracket C whilst the
door is closed as shewn in Fig. 1. When the door is partly opened (Fig. 2) it will
be seen that the link G and consequently the aperture H therein will assume such
a position with respect to the head of the stud e that the link G cannot be
removed or disconnected from said stud. When, however, the door is closed the
aperture H will register with the head f of stud e and the link G may then be
readily raised out of engagement with said stud, the rotatable arm E permitting
such movement of said link. When such disconnection of the arm G from the
stud e is effected, the links F, G, will owing to the turning of arm E assume the
pendent position against the door frame (Fig. 3), where they will be out of the way
and the door may then be opened and closed in the usual way.
When the device is in the operative position (Fig. 2) it will be held in the

page_text: slightly open position but cannot be opened to a greater extent, nor can the holder
be disconnected from the door bracket C, the parts being so constructed, as before
described, that such disconnection can only be effected when the door is closed.
Consequently it is obvious that when the checking or holding device is applied to
a door and door frame, the door may be left ajar for ventilation or other purposes
without any danger of an intruder being able to gain entrance to the apartment.
It is also obvious that the device will effectually prevent a burglar from gaining
entrance to an apartment even after the lock of the door has been picked or
.broken.
Instead of attaching the bracket C to the door and D to the door frame, C may
be attached to the frame and D to the door, and instead of the two studs e, el, only
one stud need be provided as two studs are provided for use alternatively either to
-a right or left hand door as before stated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The door check or door holder comprising the bracket adapted to be fixed to a
door and provided with the horizontal projection having the upwardly and down-
wardly projecting headed studs e, e¹; the bracket adapted to be connected to a
door frame or door casing and having a journal aperture; the rotatable arm having
the trunnion journalled in the aperture of the bracket and secured to said plate;
-a link or arm connected in a hinged or pivotal manner to said rotatable arm; and
a second link or arm connected in a hinged or pivotal manner with the first named
link or arm and having an aperture shaped in conformity with the heads of the
studs of the door bracket, substantially as described and shewn.
