Improvements in Apparatus for sing Doors and Preventing
Slamming to of the same.
We, JOSEPH HENRY BEAN of Upper Mill Hill, Hardware Merchant, and WILLIAM
GAINES of Tolson Street, Sunny Bank, Manager both of Leeds in the County of
York, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to provide apparatus for closing doors and preventing
slamming of same, such improvements having reference to a patent granted to us
dated the 15th day of May 1886 No. 6565.
In these improvements we employ the ordinary metallic cylinder named in the
specification of the aforesaid patent, which is firmly secured to the door frame as here-
tofore, the spring, piston and piston rod therein are also of a similar construction to
those referred to in the specification of the aforesaid patent.
These improvements are intended to ensure a more perfect steadiness of action
than heretofore in the working of the apparatus. At the outer end of the piston rod
is mounted a pulley, this pulley is engaged within a link or slotted arm, such arm
being hinged to a bracket attached to the casement at one end hereof, and the other
end of such link or arm is coupled to a rod of suitable length connected to a stud or
bracket on the door frame
On the door being opened a radial movement is imparted to the link or slotted arm
by the rod attached to the door frame. The aforesaid pulley being engaged with
such link or slotted arm rolls therein, causing the piston to be withdrawn from the
cylinder and the spring therein to be compressed.
On the door being released the spring operates upon the piston through the medium
of the pulley, bringing back the link or slotted arm to its original position and closing
the door.
The ordinary atmospheric compression takes place in the cylinder, retarding the
spring at the end of its stroke and thus preventing the slamming of the door.

We, JOSEPH HENRY BEAN of Upper Mill Hill, Hardware Merchant and WILLIAM
GAINES of Tolson Street, Sunny Bank, Manager, both of Leeds in the County of
York, 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 object of our invention is to provide apparatus for closing doors and preventing
slamming of same, such improvements having reference to a patent granted to us
dated the 15th day of May 1886 No. 6565..
In the accompanying drawings Fig. 1 is a plan shewing our improvements with
cylinder attached to door casement,. Fig. 2 is a part front elevation of same and
Fig. 3 is a plan shewing our improvements with cylinder attached to the door.
In these improvements. we employ the ordinary metallic cylinder A named in the
specification of the aforesaid patent. The spring, piston and piston rod therein are also
of a similar construction to those referred to in the Specification of the aforesaid patent.
These improvements are intended to ensure a more perfect steadiness of action than
heretofore in the working of the apparatus. At the outer end B of the piston rod
is mounted a pulley C, this pulley C is engaged within a link or slotted arm D, such
arm D being hinged to a bracket E attached to the casement F at one end, and the
otlier end of such link or slotted arm D is coupled to a rod G of suitable length
connected to a stud or bracket H on the door as shewn at Fig. 1.
In some cases we dispense with the rod G and bracket H, and attach the cylinder A
in a suitable position on the door J as shewn at Fig. 3, and to the outer end K of
the link or slotted arm D is attached a connecting rod L coupled to a bracket M on
the casement N.
On the door being opened in each case a radial movement is imparted to the link or
slotted arm D by the rod G or connecting rod L respectively, and the aforesaid
pulley C being engaged with such link or slotted arm D rolls therein causing the
piston to be withdrawn from the cylinder A and the spring therein to be compressed.
On the door being released the spring operates upon the piston through the medium
of the pulley C bringing back the link or slotted arm D to its original position and
closing the door.
The ordinary atmospheric compression takes place in the cylinder retarding the
spring at the end of its stroke and thus preventing the slamming of the door.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
The arrangement of link or slotted arm D in combination with pulley C and
various parts forming the apparatus, applied and operating substantially as and for
purposes herein set forth.
