Improvements in Bolts for Fastening Windows, Doors, and Gates, and
for other such like purposes.
JOHN WHITEHEAD 42, Anglesey Street Lozells, Birmingham in the County of
Warwick, Art Metal Worker. I do hereby declare the nature of this invention to
be as follows
This invention relates to bolts for use upon windows as sash fasteners, and upon
doors, gates, and wherever such like fastenings are required.
In carrying this invention into effect, I proceed as follows. I make a round,
square, oval, or other suitable shaped bolt, but preferably flat or square, and of
suitable length, according to the purpose for which it is required, for instance, for
a window sash fastener I make one end of the said bolt slanting or diagonal shape,
and from two to three inches in length, I then make a guide or socket the same
shape, for the said bolt to slide in, the upper or top side of the guide or socket will
be provided with a long hole or slot, in which a peg or projection fixed to the bolt
will work or slide to and fro, the said peg or projection being screwed to allow a
knob or nut being screwed down on to the top of the guide or socket, thereby
locking or fixing the bolt in any desired position, and which cannot be moved
backward or forward until released by unscrewing the knob or nut, when the bolt
will slide backward or forward freely by pushing or operating the same by the
knob or nut.
Then on the lower side or bottom of the guide or socket I fix or arrange or make
as part of the socket two or more ears or projections, having holes through to allow
of its being screwed on to the window sashes, or wherever required then I provide
a catch or socket, being of the same diagonal or slanting shape as the end of the
bolt, as before described, so that when the bolt socket is screwed on to one part of
the window sash, and the catch or socket on the other part of the window sash, the
bolt can then be pushed or engaged into the catch or socket, and the knob or nut
then screwed down on to the top of bolt socket, thereby locking or fixing the bolt,
as before described.
The improvements and advantages of this invention as a window sash fastener
is that it forces or pushes the sashes apart thereby affording ventilation, and
prevents rattling of windows, and another advantage is with having the end of the
bolt made of a diagonal or slanted shape, and the catch or socket of a corresponding
shape, it always has a tendency to force or lift up or bring both sashes to the same
level, as it very frequently happens that the two sashes do not come up to the same
level, the consequence being that ordinary sash fasteners are very often broken
through straining to get the two sashes up level with each other when fastening
the window.
Therefore my invention possesses the advantages of wedging the window sashes,
and prevents the rattling in windy weather and further with being adjustable to the
variations of sashes, for in case one sash is lower than the other, it will on account
of the diagonal, or slanting end bolt, readily adjust itself, also this invention affords
greater security as a fastening as by screwing down kaob or nut, it is locked or
fixed as before described, and cannot be opened or forced back from the outside of
window, which can easily be done with ordinary sash fasteners.

page_text: For doors, gates, and other such like purposes, I make the bolt longer and
diagonal or slanting at both ends, so that it can be used for right or left hand
purposes, and the lock nut or knob will act in the same manner as before described,
in some instances I may use a loose washer or collar, in conjunction with the lock
nut or knob, for locking or fixing the bolt, with the difference also that I shall
make the slot or hole in the top guide or socket longer for the peg or projection
connected with the bolt to work in, and the catch or socket for the bolt to push or
engage into, will be made same as before described either by bending a piece of
wrought metal to the proper diagonal or slanted shape, with two or more ears, or
projections, having holes through to allow of its being screwed on the door frames,
cases, or wherever required the catch or socket may be closed in at the sides if
desired instead of being left open.
In nearly all instances I should place the lower part of the slanted or diagonal
bolt nearest to the woodwork, whether upon window sashes, or, door frames, so that
when engaged in its catch or socket, it will have the effect of forcing or pushing,
thereby keeping the door, window, or gates firmly fastened, as in all cases it will
act on the wedge principle. I may make the bolts, catches, and sockets of cast,
stamped or pierced metál óf any suitable description and of any size.

Improvements in Bolts for Fastening Windows, Doors, and' Gates; and
for other such like purposes.
I, JOHN WHITEHEAD, of No. 42 Anglesey Street, Lozells, Birmingham, in the
County of Warwick, Art Metal Worker do 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 :-
This invention relates to bolts or fasteners for windows, doors, gates, and the like
and consists principally in making a sliding bolt in such a manner as to be
applicable for a window fastener or for a door bolt.
My invention consists essentially of a bolt having a taper or wedge shaped
extremity which is capable of engaging into a socket of a similar configuration, and
wedging itself therein.
My invention consists further in a screw arrangement whereby the bolt aforesaid
may be securely fixed in its closed position.
I will describe my invention by reference to the accompanying drawings, the
letters of reference indicating similar parts throughout.
Figures 1. 2. 3 and 4 illustrate respectively a side elevation, a plan, a vertical
section, and an end elevation of my invention applied to a window fastening.
Figures 5 and 6 represent a side elevation partly in section and a plan of my
improved bolt detached from the 'case.
Figures 7 and 8 represent a side elevation and plan of my invention applied to 'a
bolt applicable for doors, gates and the like.
B is a square guide provided with a slot 6 and A is the bolt having a taper or
wedge shaped end C. D is a screw stud projecting through the slot b and furnished
with a screw knob or fly nut E and a washer F. H is a taper or wedge shaped
socket into which engages the taper or wedge part of the bolt C. I represents
part of the lower sash and J part of the upper sash of a window. In Figure 1
and 2 the fastener is represented in its closed or locked position with the taper
end C, pressing against the taper part of the socket H and forcing the two sashes
apart against the sides of the window frame, thus preventing them from shaking.

page_text: When in this position the screw knob is screwed up tightly on the case which locks
the bolt in its closed position. In Figures 7 and 8 is represented a bolt suitable
for doors or gates and the like.
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 provided with a taper or wedge shape end or ends which engage
into a similar shaped socket, the bolt being locked on its closed position by the
screw arrangement substantially as and for the purpose herein before described and
illustrated.
