IMPROVEMENTS IN DOOR SPRINGS
Year: 1885

page_text: I JOHN WILLIAM WESTON of Blue Island, Cook County, Illinois, U.S.A. Civil
Engineer, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN DOOR SPRINGS," to be as follows:-
The object of this invention is to so construct or arrange certain appliances in
connection with spring door closers that perfect control can be obtained over any
weight of door or gate and said door or gate be closed with any degree of velocity
and without noise.
For the purpose of my invention I fit a strap, a socket or a bracket to a door or
gate frame and attach thereto by swivel or other connection a segmental rod, bar
or plate on which a helical spring can be arranged, this being held by a screw cap,
a button, or other appliance.
To the door or to the gate I attach a bracket, socket, or strap, part of which
encircles the segmental rod, bar, or strap, and bears against the spring, or it may
be springs so that when the door or gate is being opened the spring is contracted,
and on the door or gate becoming free the spring expands or rebounds and causes
the door or gate to close gently or rapidly according to the strength or number of
the springs employed.
The above applies to single doors or gates having a movement in one direction
only, but with double or swing doors or gates I attach a socket or bracket to the
door and pass a segmental rod, bar, or plate through it, a spring being on either
side of the door or gate to return or close the door to its normal position or on
jar" as desired. The two ends of this segmental rod, bar, or strap, would lie
secured to the door frame the post or the wall according to circumstances.
Instead of a socket or bracket being on the door or gate, a plate on each side of
a hole in the door through which the segmental rod bar, or plate may be passed,
can be used to bear against the springs.
I have mentioned the spring or springs as being on the segmental rod, bar, or
strap, but it or they may be within the same.

page_text: I JOHN WILLIAM WESTON of Blue Island, Cook County, Illinois, U.S.A. Civil
Engineer, do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement:-
The object of this invention is to so construct or arrange certain appliances in
connection with spring door closers that perfect control can be obtained over any
weight of door or gate and said door or gate be closed with any degree of velocity
and without noise.
The invention is clearly shown in the annexed drawings Figures 1 and 2
illustrating it applied to a door A. and top rail B.
C is a strap, a socket or a bracket attached by swivel or other connection D to a
segmental rod, bar or plate E on which a belical spring F is arranged, this being
held by a screw cap or a button G pressing against as in Figure 1 or fitting a
cup H on the door frame B as at Figure 3 or into a recess in the door frame as at
Figure 4.
To the door A (or to the gate) I attach a bracket, socket or strap I part of which
encircles the segmental rod, bar or strap E and bears against the spring F, or it
may be springs, so that when the door or gate is being opened the spring is con-
tracted and on the door or gate becoming free the spring expands or rebounds and
causes the door or gate to close gently or rapidly according to the strength or
number of the springs employed.
According to Figure 5 the spring F is enclosed in a slotted tube J which guides
the bracket I. In Figure 6 the tube J telescopes into the socket tube K affixed to
the door jamb or style L.
The above applies to single doors or gates having a movement in one direction
only but with double or swing doors or gates I attach a socket or bracket to or
make an aperture or a notch in the door and pass a segmental rod, bar or plate E
through it (see Figure 7) a spring or springs F being on either side of the door A
or gate to return or close the door to its normal position or "ajar" as desired. The
two ends of this segmental rod, bar or strap E may be secured to the door frame or
simply with the ends butted placed in apertures M in the door post, or into the
wall according to circumstances.
I have mentioned the spring or springs as being on the segmental rod, bar or
strap but it or they may be within the same if of tubular form as in Figure 6.
Figures 8 and 9 represent my invention applied to a swing door the spring F
and segmental rod, bar or strap E being within a kind of box plate N let into a
floor P or strap Q as an extension or arm of the pivot block R having the spring
pressing on either side for returning the door to its normal position after being
pushed open to the right or to the left.
To prevent abrasion of the spring F I fit the strap Q with a small bearing
wheel S which also tends to keep the pivot T and pivot block R true.
U is a cover plate to the box N.
If the door or gate has to be permanently kept ajar the spring is set for that
object or in the case of double or a swing door one spring may be slightly weaker
than the other or one spring may be slightly longer than the other.

page_text: 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. The improved construction and arrangement of apparatus termed a door or
gate spring and its method of operation as described with reference to the annexed
drawings.
2. In connection with a door spring a segmental rod or its equivalent, holding or
containing a spring of the form described arranged substantially in the manner
shown in the drawings for the purpose set forth.
