end of channel farthest from the door, then the tumbler is out of action.
POSITION ON DOOR.
The door fastener is made as an effectual check against opening the door from
the opposite side to which the door fastener is fixed. It is always fixed on the
door post, on the opposite side to the hinges, on the side of door generally called
the inside.

Improvements in Door Fastenings.
THOMAS JACKSON, 371, Worsley Road, Winton, near Manchester, Brass Finisher,
and EDWARD WITHINGTON, 382, Worsley Road, Winton, near Manchester, Pattern
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:-
The door fastener is composed of metal, and the component parts are three
in number namely for reference. Fig. I A bracket, B tumbler, & C pin.
CONSTRUCTION OF PARTS.
The bracket A Fig. I is a piece of metal, channel shaped at one end, and
extended at the other end to form a dovetail, a hole goes through centre of dovetail,
for the purpose of being fastened to doorpost with a small wood screw.
The channel sectioned end, being at right angles to the face of the dovetailed
end. The channel sectioned end of bracket, is made to receive the tumbler B
and for that reason has a hole drilled through both sides or vertical faces of
channel sectioned end to fit the pin C, upon which the tumbler B works easily
with a semicircular motion. That part of the bracket A, marked with a dotted
line, shows where the door closes, (the inside of door when closed), and in the
space to the left the tumbler B passes from one side of the space to the other.
Fig. II shows the fastener, as fixed in the doorpost F, as viewed from the opposite
post with the door open, the bracket A is let into the doorpost, the dotted line
shows the inside of door when closed the tumbler B shows the position unfastened.
Fig. III shows the fastener, as fixed in the doorpost as viewed from inside, of
door, the dotted line shows the inside of door when closed, the tumbler B shows
the position unfastened.
Fig. IV is a sectional position of the fastener, the door, and the doorpost, when
fastened as in Fig. V, the bracket A, the tumbler B, the pin C, passing through
the channel spaced end of bracket A. and tumbler B, the door stop D, the door E,
the doorpost F.
Fig. V shows the fastener with the tumbler B turned down in front of the
closed door, the dotted line shows where the door closes, (the doorpost), the bottom
of the channel in the bracket A, prevents the tumbler B from passing beyond the
position required.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
(1st) The principle of fastening doors with a hinged tongue or tumbler as
described in this specification.

page_text: (2nd) The principle of fixing the hinged tongue or tumbler so that it retains its
place in position without having either catch, spring," or any other device
whatever.
66
(3rd) The principle of a hinged tongue or tumbler of metal hinged upon a
fixing which is fixed upon the doorpost, and which the former swings in a semi-
circle from one position where it is at rest and out of the way, to another position,
where it falls after the completion of the semicircle into its place, that place
being the most effective for the purpose of fastening the door.
