PROVISIONAL SPECIFICATION.
Improvements in Ash-pit and other Doors, and the Method of
Locking or Fastening same.
I, GEORGE WHITTAKER, of 109 Shakespere Terrace, Burnley, in the County
of Lancaster, Traveller, do hereby declare the nature of this invention to be as
follows:-
Its objects are to obtain greater stability and security, particularly in respect to
ash-pit and other doors of a similar nature, and to prevent their being opened, or
interfered with, by any but a properly authorized person or official.
The method generally used for fastening ash-pit doors is of a very primitive
nature, and enables children and others to open them quite easily; obtain access to
the contents of the ash-pit, and strew them about the street or court, creating a
most objectionable nuisance and insanitary condition, quite contrary and opposed to
the high state of hygienic efficiency which corporate, municipal, and other sanitary
authorities desire to attain.
In order to obviate the objectionable features which now exist, and to success-
fully accomplish the objects of this invention, I construct the door in the following
manner viz. :-
The frame may be formed of concrete, earthenware, wood, iron or other suitable
material.
When concrete is used, it may be so formed as to enclose one or more tubes
which may either be left in permanently or drawn out when the matrix has set,
these tubes (which may be composed of any suitable material) are to strengthen the
concrete and reduce its cost.
The front of the frame is recessed or rebated so as to take a door, (preferably
of sheet iron) which fits into the recess and stands flush with the front of the
frame.
The frame is also provided with two or more hooks, or projections, to support
the door and act as a guide when placing it in position, and to retain it there.
The door, (which may be made of any suitable material) is provided with a lock
or fastener consisting of a hollow cylindrical box or "case," having an opening or
aperture in the circumference, communicating with a slot in the outer side or end,
so as to admit of the insertion and withdrawal of a key,-the "case
square, rectangular, or any other shape.
may also be
One end of a shaft or bolt, either triangular in section or having a peculiar
shaped extremity (corresponding with the cavity in a box key, hereinafter
mentioned), penetrates into the interior of the "case" and projects through the
head or lintel of the door-frame, to the back thereof, where a suitable bearing is
provided to support it and allow it to turn, or a stop piece or button is fixed at the
end to keep it in its proper position, and may be protected from contact with the
contents of the ash-pit by a plate or cover.
The door and the inner-side or end of the "case," which abuts against the door,
is provided with an opening (also corresponding in shape with the socket of the
key), so as to permit the triangular or peculiar shaped end of the bolt to pass
through, when it has been turned with the key, into the proper position.
When locked, the peculiar shaped end of the bolt is in such a position as to

page_text: prevent its passage through the opening in the inner-side of the "case" and the
duor, but by inserting the key and turning the bolt so as to pass through the
opening, the door is unlocked aud may be lifted out of the frame.
The key is provided with a box or socket end, having a cavity, to correspond with
the shape of the end of the shaft or bolt in the "case."
Instead of the Jock projecting beyond the outer surface of the door, it may be
applied so as to be flush therewith, the frame being recessed or sunk for that
purpose, or if desirable the bolt may be carried by a suitable bracket or brackets
attached to the frame.

Improvements in Ash-pit and other Doors, and the Method of
Locking or Fastening same.
J, GEORGE WHITTAKER, of 109 Shakespeare Terrace, Burnley, in the County
of Lancaster, Commercial Traveller, 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:
This invention relates to ashpit and other doors of a similar nature, and its objects
are to obtain greater stability and security, and to prevent their being opened or
interfered with by any but a properly authorised person or official.
And in order that my invention may be properly understood and readily carried
into practical effect, I have hereunto attached the accompanying sheet of drawings,
marked with figures and letters of reference.
Fig. 1 is an elevation, and Fig. 2 a plan of an apparatus constructed in accordance
with my invention.
The frame a may he formed of cement-concrete, earthenware, wood, iron, or
other suitable material. When concrete is used it is so formed as to enclose one or
more tubes of iron or strong galvanised barbed wire, to be left in permanently in
order to give additional strength to the frame.
The front of the frame is recessed or rebated so as to take a door (preferably of
sheet iron) which fits into the recess and stands flush with the front of the frame,
which is provided with two hooks or projections c to support the door and to
act as a guide when placing it in position, and to retain it there.
The door b (which may be made of any suitable material) is provided with a
lock or fastener, consisting of a hollow cylindrical box or case d of brass, having
an opening or aperture in the circumference communicating with a slot in the outer
side or end, so as to admit of the insertion or withdrawal of a key (hereinafter
mentioned).
Provision is made for this box or case to protrude through the centre of the door
on the top side, it being securely rivetted to the door on the inner side thereof by
means of two lugs or ears.
One end of a shaft or bolt e. Figs. 1 and 4, preferably of brass, having a
triangular or other peculiar shaped extremity, penetrates into the interior of the
frame a, the triangular end projecting through the head or lintel of the frame. The
inner-side or end of the box d is provided with an opening corresponding in shape
with the end of the shaft or bolt e (and also corresponding in shape with a socket
of the key). This opening in the box permits the triangular end of the shaft

page_text: to pass through when the same has been turned with the key into the proper-
position.
When, locked the peculiar shaped end of the shaft is in such a position as to
event its passage through the opening in the inner side of the box (which is.
fastened to the door in the manner hereinbefore described) but by inserting th key
and turning the shaft, so as to pass through the opening, the door is unlocked and
may be lifted out of the frame. The door is thus prevented from being opened.
except by the application of the key.
A chain of galvanised iron, and of suitable strength is secured to the door on.
the inner side and to the bottom portion of frame a. The door is thus prevented
from being carried away when lifted out for the purpose of emptying the ashpit.
Instead of the box or case d projecting beyond the outer surface of the door, it
may be applied so as to be flush therewith, the lintel or head of the frame a being
sunk for that purpose; or if desirable the shaft e may be carried by a suitable-
bracket or brackets attached to the frame.
The key is provided with a box or socket end having a cavity to correspond with
the end of the shaft or bolt e.
In order to simplify the operation of locking or unlocking the door, the inner
end or extremity of the shaft e. is prepared to receive a pin or cotter g, through its.
diameter, a cavity h, being formed in the lintel of the frame on the bick or inner-
side to admit of this pin being inserted.
When the shaft has been turned by the key to exactly the proper position either-
in fastening or unfastening the door, the ends of the pin g are permitted to come in
contact with and to rest upon two buffers or banks j formed of cement on the lower
side of the cavity herein before described. By this means no skill or judgment is
needed by the operator, the shaft being effectually checked and prevented from.
turning too far in ether direction.
Having now particularly described and ascertained the nature of my said i ve
tion, and in what manner the same is to be performed, I declare that what [.
claim is :-
1. The construction of the cylindrical box or case with openings on the outer and!
inner surfaces of same, as described.
2. The peculiar shaped end or extremity of the shaft or bolt, and the key to turn.
same, as described.
3. The checking or limiting of the action of the shaft by the insertion of a pin
or cotter at the plain end thereof, and the application of buffers in the cavity of the
frame, for the purposes described.
4. The application of concrete for the construction of the frame, and the enclosing
of metal tubes within the same, as described.
5. The general arrangement and combination of the parts substantially as shewa.
and described.
