Improvements relating to Door Holders.
I, OLIVER BECK, of 33, Salisbury Road, St. Albans Road, Watford, Joiner, 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:.
This invention relates more especially to swing doors such as are used in public
buildings and other places but is also applicable to other doors and has for its
object means for restraining the swinging motion of the door and whereby the
amount of closure of the door can be regulated.
According to this invention, two brackets are secured one on the door frame
and one on the door, and to these brackets rods are pivoted.
To the rod attached to the door frame another and smaller rod is pivotted and
this latter rod is adapted to slide within the rod attached to the door which is
hollow. A pin can be inserted in one of several places in this smaller rod, and
projects up through a slot in the outer rod. As the door is opened or closed the
smaller rod slides in the outer rod so far as is permitted by the pin which comes
in contact with the ends of the slot and thus regulates the amount of closure.
In order to more clearly indicate the nature of this invention reference is had
to the accompanying drawings in which,
Fig. 1 is an elevation of a device constructed according to this invention show-.
ing the door in a fully closed position, and Fig. 2 is a plan showing the door in
an open position and the pin being inserted so as to permit of only a partial closing
of the door as indicated in dotted lines.
The bracket A is secured to the door frame by screws or other means at a con-
venient height and the bracket B is attached to the door at a suitable distance
from the bracket A and at a corresponding height. To these brackets are pivoted
the rods C and D. The pivots a b are constructed somewhat as shown, so as to
permit of a universal movement or any other type of universal joint may be employed.
The pivots a bare preferably constructed so that the rods C D cannot pass beyond
a right angular position and they cannot therefore turn inwards and probably
become broken or damaged. The rod C pivoted to the bracket A is provided at its
other end with a pivot c to which is attached a rod E of smaller diameter. The
rod D pivoted to the bracket B is formed for some distance hollow and the rod E
slides within it. A pin or screw e can be inserted in one or other of several holes e¹
and projects up through a slot d formed in the rod.
As the door is opened the rods C D move slightly on their pivots a band the
rod E slides in the rod D. During this action the parts take up the position shown
in full lines in Fig. 2. As soon as the door is released, it swings back until the
pin e comes in contact with the end of the slot & when further movement is pre-
vented.
It will thus be seen that the amount of closure of the door can be regulated
according to which of the holes e¹ the pin e is inserted into. Thus in Fig. 1 the
door will entirely close but in Fig. 2 only to the angle shown in dotted lines.
When used for heavy doors or otherwise if desired either the rod C or the rod D

page_text: is provided with a spiral spring for a portion of its length or is constructed as a
spring barrel so as to permit of a slight movement of the door beyond the extreme
position to prevent injurious jerking of the rods.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
(1) An arrangement for regulating the closure of swing and other doors con-
sisting of brackets attached one to the door frame and one to the door, rods pivoted
to the said brackets a third rod pivoted to one of the before mentioned rods and
sliding in the other and a pin inserted in one of several holes in said third rod and
projecting through a slot in the hollow rod substantially as described and for the
purposes specified.
(2) An improved arrangement for regulating the closure of swing and other
doors consisting of brackets A, B, pivots a, b, rods C 1), rod E pivoted at c to rod C
and sliding in rod 1 and pine and adapted to be inserted in one of the holes e
and to project up through the slot d all arranged and operating substantially as
described with reference to the drawings and for the purposes specified.
Dated this 12th day of April 1898.
