COMPLETE SPECIFICATION.
An Improvement Connected with Draw and Push Bolts for Furniture,
Doors, Windows, and the like.
I ROBERT MUIR PETRIE of 17 Faraday Road, Leyton, Essex, Carpenter do
hereby declare the nature of my said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement.
This invention relates to a certain detail appliance connected with draw and
push bolts and is applicable to movable panels, to cupboards, to Book Cases, and
other movable parts of Furniture, to Street and Room doors of dwelling houses
Offices and buildings generally, also to windows whether they lift up, slide or are
hinged, so that the holt can be locked when in a shot to or a drawn back position, the
appliance being connected to the bolt as a hinged or flap handle to take into an
aperture of the front or outside plate and to preferably lie flush therewith.
When the bolt has to be shot or withdrawn the flap handle is removed from the
recess and used as the lever for moving the bolt.
My invention is clearly shown in the three examples on the annexed drawings
Figures 1 to 8 inclusive.
Figures 1 and 2 are sectional and face views respectively of a flush bolt suitable for
Cupboards, Bookcases, Cheffioners, Ordinary House Doors and others.
Figures 3, 4 and 5 represent perspective views of a barrel bolt showing the different
positions the flap handle occupies. Figures 3 and 5 having the flap handle shut down
and the bolt home, and shot, respectively.
Figures 1 and 4 have the flap handle turned up so that it can be used as a lever by
which the bolt can be moved.
I purpose pivotting the flap handle A to a stud or ears B of a bolt C said flap
handle fitting the side walls of the box, plate, or barrel D whether down in the
forward or the backward position to nip in place but at Figure 7 I show the flap
handle A hollow and provided with a spring and button piece F to ride against a
curved stud B provided with a pin on which the flap handle A can be raised and
turned so that when the bolt C has been moved along in the required direction the flap
handle A when turned down to lie flush with the front or other plate or of the

page_text: barrel D as the case may be is retained in that position by the action of the
spring E.
It will be observed from the drawings that the flap handle A when turned down
whether the bolt C be shot forward or drawn back always lies flush and fills up the
opening in the front plate D so that no gap is left other than that G for the insertion
of the finger nail to lift the flap handle A by said gap G being only of sufficient depth
to enable the finger nail to be inserted for taking under the notched end of the flap
handle A when it has to be lifted for moving the bolt along.
The bolt as a "Flush" in its simplest form is applicable to the top edge or bottom
edge of a Book case or other door, its action being identical in both cases so that the
flap handle A does not require to be removed and reversed to adapt the bolt to the
particular position it has to occupy.
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
The construction of flush, barrel, and like bolts, with a plain hinged, or pivotted
flap A, which when turned up can be used as the handle or lever for moving the bolt
and completely fill the gap made in the front plate or barrel when said flap is turned
down, said flap then lying flush with the front plate or barrel and locking the bolt in
the desired position (locked or unlocked); as described and substantially as shown on
the annexed drawings.
