I JOSEPH TIMOTHY HOPKINSON, of 20 Fearon Street East Greenwich, in the
County of Kent and of 15 Snow Hill, Birmingham, in the County of Warwick
Tool Maker, 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 :-
According to my invention I make a box or staple for door bolts and chains with
an angle plate for attachment to the door frame so that there are two sets of fixing
screws at right angles to each other. This arrangement prevents the box or staple
from being forced off.
Boxes or staples for door lock bolts and door hinge bolts I make of similar
construction.
Butt hinges are similarly formed of two angle plates attached to the door and
frame respectively.
I make outside and inside plates for double hinge plates for butt hinges to act
square for doors and each hinge showing four equal recess pieces and staples. I
make the plates for screwing one on the right side the other plate on the left side
to the side of the window and screw them with fixing screws for both sides of the
window one for the right side the other for the left side at right angles to each
other so that the sets of fixing screws cannot either draw or force out the other set.
The fixing screws are placed at right angles to each other to prevent them from
being forced off.
Figures 1 and 2 of the drawings hereto annexed show perspective views of door
bolt fastenings a constructed with angle plates 6 to fix them to the door post or
frame with screws placed at right angles in accordance with my invention.
Figures 3 and 4 show perspective views of door lock bolt fastenings a constructed
with angle plates b for fixing them to the door post or frame with screws inserted at
right angles in accordance with my invention.
Figures 5 and 6 show perspective views of door hinges constructed with four sides
so that they can be fixed with the screws placed at right angles in accordance with
my invention.
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 of door and lock bolt fastenings a in combination
with angle plates 6 fixed by screws at right angles to each other as hereinbefore
described with reference to Figures 1. 2. 3 and 4 of the drawings hereto annexed,

page_text: 2. The improved construction of hinges for doors formed with plates a and b fixed
to the door and door frame respectively by fixing screws at right angles to each
other substantially as hereinbefore described with reference to Figures 5 and 6 of the
drawings hereto annexed.
