Checks to Doors and malagous Ar
We EDWIN VERITY and JOSHUA MARLAND VERITY of Call Lane Leeds Ironmongers
and BENJAMIN BANKS of Leas Yard Meadow Lane Leeds Brass finisher all in the County
of York do hereby declare the nature of this invention to be as follows:-
The object of this invention is to arrange the mechanical action that it so distributes
the power of the spring as to act with increased force when the door is closed and
become weaker as the door is opened.
We first construct the barrel that contains the spring and piston in the usual
adopted way.
We next construct a bracket which is attached to the framing of the
door, to one part of which we fix the guide rod or stay and to the other side of this
bracket we also fix an arm provided with an elongated slot in which the guide rod
and end of piston slides, the opposite end of this arm being attached to the door by
an hinged bracket so that when the door is opened the end of piston slides in the
inclined plane of the aforesaid elongated slot.
