Improvements in Bolts for Doors, Gates and the like.
1, JOHN GERRARD BAKER, of Blean, near Canterbury, in England, Gentleman,
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
My invention relates to improvements in bolts, and the object of the invention
is to design a form of bolt particularly adaptable for gates and outhouse doors,
which may be operated from either side of the gate or door and it consists essentially
of a bolt formed up of a single sheet of metal U-shaped in cross section and having
struck out of it at right angles thereto à tongue with lateral end projecting cars
leaving a corresponding slot, such tongue being designed to extend through a slot
in the door and the bolt being held in suitable straps, the screw of one of which
extends through a slot in the bolt and is designed to limit the movement thereof
in the manner hereinafter explained.
Fig. 1, is a perspective view of a portion of a gate and the side bar thereof
showing my bolt locked in full lines and open in dotted lines.
Fig. 2, is a perspective view from the opposite side of the gate or door showing
the operating tongue to manipulate the bolt from this side of the door.
Fig. 3, is a detail of the bolt.
Fig. 4, is a detail of the supporting straps or keeper.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A is the bolt, which is preferably formed out of a single piece of sheet metal
substantially U-shaped in cross section and is provided with an end lip a A¹ is
a tongue struck out of the bolt, one end only, however, being severed. The
tongue A¹ is so struck out as to leave laterally projecting ears a¹ on each side. The
slot A2 is thus formed in the bolt with laterally projecting portions a².
B is the retaining strap or keeper for supporting the bolt next the closing side
of the door. The retaining strap B is also preferably formed out of one piece
substantially as shown and has inwardly extending ears b parallel to the face of
the retaining metal strap.
bare spikes, which are formed up on each side of the ears and are designed
to project into the wood of the door, so as to hold the retaining plates securely in
position. The spikes bare at right angles to the face of the retaining strap.
12 are holes, which are made both in the face and ears and are designed
to receive the securing screws C. The keeper D on the side frame of the gate is
formed in exactly the same way as the retaining strap and also held in position
in the same way. The retaining strap E is also formed in the same way with the
exception that it is secured in the centre only by one screw F, which extends
through the slot A2 of the bolt.
The bolt is shown in Fig. 1, shot in which position the screw F extends through
the lateral extension & of the slot A2 and thereby the door is held locked. In
order to withdraw the bolt from the outside of the door, such bolt has to be slightly

page_text: raised by catching hold of the lip a and then with drawn, the edges of the slot
passing rearwardly past the screw F.
This same operation may be performed at the opposite side of the door by
manipulating the extending end of the right angular tongue A'.
It will thus be understood that my bolt is very convenient by being enabled to
be operated on both sides of the door and serve the double purpose of being a latch
as well as a bolt.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. A bolt comprising the bolt proper provided with a slot having lateral recesses,
retaining straps for the bolts and a screw extending through the slot of the bolt as
and for the purpose specified.
2. A bolt comprising the bolt proper provided with a right angular tongue or
projection and slot having lateral recesses, retaining straps for the bolts and a
screw extending through the slot of the bolt as and for the purpose specified.
3. A bolt comprising a U-shaped plate having formed out of same a right
angular tongue with end projections so connected to the plate as to leave a slot
of similar formation having lateral recesses, and a lip formed on the end of the
plate, and suitable retaining straps and keepers for the bolt one of which is pro-
vided with a screw extending through the slot in the bolt as and for the purpose
specified.
4. The combination with a bolt formed as described, of the retaining plates
having the spikes at right angles to the face of the strap and ears parallel with
same, and screws extending through holes in the straps, so as to retain them in
position as and for the purpose specified.
