I, HENRY JOHNSON of The London Bedstead Works Aston Lane Birmingham, in
the County of Warwick Tool maker, do hereby declare the nature of this invention
to be as follows :-
I take a piece of flat iron brass or other suitable metal onto which I rivet a barrel
to receive a solid bolt, this barrel has a slot cut on the top horizontally and a slot is
also cut across the barrel for the knob or finger piece to slide and lock in.
On to the top side of the solid barrel bolt is cast or rivetted a small projection for
the purpose of locking the bolt.
The staple or counterpart in which the bolt is shot into is conical slotted on the top
so that when the bolt is slid into this staple and the knob or finger piece turned it
revolves the bolt and with it the locking projection into this conical slot and renders
it impossible to withdraw the bolt until again turned into the horizontal slot when the
bolt is unlocked and can be withdrawn.
In order that the bolt and locking portion may be drawn back flush I cut a small
slot on the end of the hollow barrel for the reception of the locking portion.
I can if preferred cast the flat plate and the hollow slotted portion in one piece and
again I can cast the solid barrel bolt the locking projection also the finger portion in
one piece, and thus save the rivetting.
On the flat portion holes are drilled to attach the lock bolt to what is desired.

page_text: I HENRY JOHNSON of the London Bedstead Works Aston Lane 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, reference being had to the accompanying
drawings and to the letters and Figures marked thereon :-
I take a piece of flat iron, brass, or other suitable metal, on to which
I rivet a barrel to receive a solid bolt, this barrel has a slot cut on the top
horizontally and a slot is also cut across the barrel for the knob or finger piece to slide
and lock in.
.
On to the top side of the solid barrel bolt is cast or rivetted a small projection for
the purpose of locking the bolt.
The staple or counterpart in which the bolt is shot into is conical slotted on the
top so that when the bolt is slid into tho staple and the knob or finger piece
turned it revolves, the bolt and with it the locking projection into this conical
slot and renders it impossible to withdraw the bolt until again turned into the
horizontal slot when the bolt is unlocked and can be withdrawn.
In order that the bolt and locking portion may be drawn back flush I cut a small
slot on the end of the hollow barrel for the reception of the locking portion.
I can if preferred caste the flat plate and the hollow slotted portion in one piece
and again I can cast the solid barrel bolt the locking projection also the finger portion
in one piece and thus save the rivetting.
On the flat portion holes are drilled to attach the lock bolt to what is desired.
This form of bolt is applicable as a sash fastener as well as for purposes in which an
ordinary bolt may be used.
If desired the end of the bolt may be made more or less pointed so as to readily
enter the staple, when not exactly opposite which often is the case when used upon
badly fitting windows.
One great advantage in this locking bolt is that a secure fastening is obtained with-
out the employment of a spring.
Referring to the Drawings.
Fig. 1. is a view of the bolt unfastened.
Fig. 2. a view of the bolt shot forward and locked.
(a) is the horizontal slot on the top of the barrel (6) the slot cut across the barrel
into which the knob or finger piece (c) of the bolt will turn as shewn in Fig. 2.
(d) is the projection upon the bolt () the conical slot in the staple and (e) the

page_text: When the bolt is slid forward into the staple and the knob or finger piece (c) turned
down into the cross slot (b) the projection (d) slides into the conical slot (f) and locks
the bolt as shewn in Fig. 2.
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
Constructing bolts the barrels of which are slotted so as to enable a projection upon
the bolt to work therein and cause the bolt to become locked substantially as herein
described and illustrated by the drawings.
