I, SAMUEL COOMBS, of No. 89, Denmark Street, Camberwell, in the County of
Surrey, Joiner, do hereby declare the nature of this invention to be as follows:-
This check is designed for the purpose of preventing doors slamming in closing
and can be used with any spring, or in combination with a spring-hinge and is
fitted into a mortice made, either in the hanging stile of the door, or
sponding post or jam of the door frame.
corre-
A metal case similar to a mortice lock, is fitted with a lever, moving on a
fulcrum, at its lower end, the upper end being provided with a nose-piece or
push, passing through an opening in the face plate of the case.
Behind the
lever is fitted a roller or wheel. turning on an axis, between which lever and
roller is a wedge shaped block, which is provided with a covering of webbing, or
other suitable material.
i
The pressure of the edge of the door in closing" upon the nose-piece of the
lever, presses upon the wedge shaped block, causing it to rise between the same
and the roller, the friction generated by the action, acting as a check, allowing
the door to close quietly.
Tpon the door being opened, the wedge piece falls into position by its own
weight. pushing the lever forward and allowing the nose piece or push to again
project from the face-plate, and ready to be again acted upon by the edge of the
door.

An Improved Door Check.
I, SAMUEL COOMBS, of 89. Denmark Street, Camberwell, in the County of
Surrey, 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:-
The door check which constitutes my invention is intended for the purpose
of preventing doors slamming in closing, and can be used in combination with
any suitable spring, or spring hinge, for closing the door. The said door check
is fitted into a mortice, made either in the hanging style of the door, or in the
corresponding post, or jamb, of the door frame.
I will describe the door check made in accordance with my invention with
D

page_text: reference to the accompanying drawing. Figure 1 shewing in vertical section
the case containing the mechanism of the check applied to the post, or jamb, of
a door frame with the parts in the position they assume when the door is open.
Figure 2 is a similar view, but with the parts in the position they assume when
the door is closed. Figures 3 and 4 are corresponding plans. A is a part of
the post or jamb, of the door frame, and B is part of the hanging style of the
door. Any ordinary, or suitable, arrangement for effecting the closing of the
door can be used.
A casing C, which may be similar to that of a mortice lock, is fitted with a
lever D, centered on a fulcrum pin at its lower end, and having, at its upper
end, a nose, or push-piece 2, passing through an opening in the face plate of
the casing C, and when the door is open, projecting from the post, or jamb, A.
Behind the lever D is fitted a roller, or wheel, E, turning on an axis e, and
between the said lever D, and roller, or wheel, E is a wedge shaped block F
which is preferably provided with a covering of webbing, or other suitable
material f. The edge of the hanging style of the door, in closing, comes in
contact with the nose, or push piece of the lever D, and moves the said lever
inwards upon its centre, so that it presses upon the wedge shaped block F, caus-
ing it to rise between the lever D, and the roller, or wheel E, the friction, caused
by this action, acting to retard the completing of the closing of the door so as
to cause it to close quietly. Upon the door being opened the wedge piece F
descends and moves the lever ), forward so that the nose, or push-piece, again
projects from the opening in the face-plate of the casing, ready to be again acted
upon by the edge of the hanging style of the door when it is again closed.
It is essential for the proper action of the device that the roller, or rotatable
wheel, be used for the wedge piece to bear against as only by this means will
the wedge-piece be capable of being actuated as described.
Having now described and particularly ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is:
In a door check, the combination of a lever provided with a nose, or push
piece projecting so as to be acted upon by the door before it becomes fully closed
a roller, or wheel, at the rear of the said lever, and a wedge piece situated
between the said lever and roller, or wheel: substantially as hereinbefore de-
scribed and illustrated by the accompanying drawing.
