PROVISIONAL SPECIFICATION.
Improvements in Bolts for Doors and other articles.
We HARRY MILHAM, Joiner, and THOMAS BROADBENT, Toolmaker, both of
3, Summer Road, East Molesey, in the County of Surrey, do hereby declare the
nature of this invention to be as follows:-
According to our invention we provide a cylindrical bolt of suitable metal
adapted to fit into and work longitudinally in a tube furnished with a flange at one
end. The tube is housed in a circular hole bored for it in the edge of the door or
other article to which it is to be applied and the flange is let in flush and serves to
secure the tube and bolt in proper positions.
The bolt is capable of some rotary motion in the tube and has an operating
lever or handle fixed to it in suitable position. The said handle passes through a
slot cut in the tube and extends through a corresponding aperture cut in the face
of the door or other article which aperture is provided externally on the face of
the door with a slotted metal cover plate.
When the bolt is horizontally disposed two notches are formed in the lower side
of the slot of the said cover plate, in the fore or back one of which the handle rests
when turned down according as the bolt is shot or withdrawn, and the said handle
may terminate in a heavy ball to keep it down.
When the bolt is to be fixed vertically one notch is formed in the slotted cover
plate of such shape and configuration as to hold up the bolt when shot and laterally
moved if at the door head; or in the same manner when withdrawn if at the foot
of the door or article.
This bolt is applicable to any kind of door or other article to be fastened; it is
handy and inexpensive, and by our construction but little cutting of the wood is
required, and the appearance is neat and unobjectionable.

page_text: According to our invention we provide a cylindrical bolt a of suitable metal
adapted to fit into and work longitudinally in a tube furnished with a flange cat
one end. The tube. is housed in a circular hole bored for it in the edge of the door
or other article to which it is to be applied, and the flange c is let in flush and
serves to secure, by screws passing through it, the tube and bolt in proper positions.
The flange c is not essential, but it is a simple and advantageous construction and
therefore preferred.
The bolt is capable of some rotary motion in the tube and has an operating lever
or handled fixed to it in suitable position. The said handle passes through a slot bl
cut in the tube and extends through a corresponding aperture e¹ cut in the face of
the door or other article, which latter slot e¹ is or may be provided externally with
a metal cover plate such as ffixed to the face of the door and having a slot n
formed therein.
When the bolt is horizontally disposed as illustrated in Figs. 1 to 4, a notch or
two notches n' n² is or are formed in the lower side of the slot n of the said cover
plate, in the fore or back one of which the handle d rests when turned down to
locked position according as the bolt is shot or withdrawn, as respectively shown in
Figs. 3 and 1, and the said handle may terminate in a ball or weight such as d¹ to
keep it down. Any convenient aperture such as a simple hole lined with metal or
not may be provided in the frame of the door or flap for receiving and holding the
outer end of the bolt when shot as indicated in the drawings.
When the bolt is to be fixed vertically one notch only is formed in the slotted
cover plate of such shape and configuration as are illustrated in order to hold up
the bolt when shot and laterally moved if at the door head as shown at n' at the
top of Fig. 5; or in the same manner when withdrawn if at the foot of the door or
article, as illustrated at 2 at foot of Fig. 5.
This bolt is applicable to any kind of door, flap, or other article to be fastened;
it is handy and inexpensive; and by our construction but little cutting of the wood
is required, and the appearance is neat and unobjectionable.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be perforined, we declare that what we
claim is:-
.
The bolt for doors and other articles constructed and arranged substantially in
the manner hereinabove described and illustrated in the accompanying drawings.
Dated this 27th day of February 1893.
