PROVISIONAL SPECIFICATION.
Improvements in or relating to Bolts or Fastenings for Doors
and like purposes.
I, OTHO HENRY STEED Junior, of 118 Somerset Road, Handsworth,
Mechanician, do hereby declare the nature of my said invention to be as follows:-
My invention for "Improvements in or relating to bolts or fastenings for doors
and like "purposes" consists substantially of the construction and arrangement, of
the following parts, my aim and object being the actuating of the same in a simple
and efficacious manner.
I will describe my invention thus :-
I construct and employ a metallic plate of a required shape and configuration of
the kind now used to bolts for doors this plate is provided with carriers, two or
more for carrying the bolt and guiding the same. The bolt I propose using would
be a bar of metal, square, or of a 'form right angles in cross-section, the carriers.or
guides of this bolt as above named would correspond. The inner end of this bolt
has a slot cross-wise extending about half its depth. Near to the inner end of this
bolt is a metallic plate of a required form, the surface being recessed forms a
surface edge, of a width and depth sufficient to engage in the slot of the bolt, and
is provided with a handle or lever at its edge, and by means of which it is
actuated. This plate moves upon a pin or axis which is secured to the plate in au
eccentric position on the plate on the door which has the carriers, so that the bolt
is controlled by the edge of the plate, engaging in the cross-slot, by the power of
the lever thereon, and the bolt is carried into the "shoot"in its outward motion,
and withdrawn upon its return.
In some cases the door plate may be dispensed with and the carriers and bolt
affixed to the door, and also the plate as above set forth.

Improvements in or relating to Bolts or Fastenings for Doors
and like purposes.
1, OTHO HENRY STEED, Junior, of No. 118 Somerset Road, Handsworth in
the County of Stafford, Mechanician 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 consists, as hereinafter described, of "Improvements in or relating
to bolts or fastenings for doors or like purposes," whereby the construction and
arrangement for shooting or withdrawing of the bolt is much simplified.
My invention consists essentially of a metallic plate of the required shape and
size and similar to those-commonly used for door bults. The said plate I provide
with carriers or guides for holding the bolt, I use preferably a square bolt, that is

page_text: to say, square in cross section, though I do not confine myself 'to any particular-
form of bolt. The terminal end of the said bolt has a cross slot and a projecting
stud or peg or its equivalent. I provide a metallic cam furnished with a turned up
edge or flange on its periphery of a required size to engage in the slot at the bolt
aforesaid, one end of the said cam is furnished with a handle or lever. The said cam
I pivot to the plate near the end of the bolt in an eccentric position so that by the
movement of the cam the bolt is moved in one direction or the other
I will describe my invention by reference to the accompanying drawings the
letters of reference indicating similar parts throughout.
Figure 1 represents a front elevation of a door bolt constructed in accordance
with my invention showing the bolt withdrawn from the staple box.
Figure 2 represents a front élevation and Figure 3 a side elevation of a door
bolt showing the bolt shot into the staple box.
Figure 4 represents a portion of Figure 3 in vertical section.
Figure 5 shows the cam in front elevation and cross section.
Bis part of a door frame to which is attached the staple box D and A part of
a door to which is attached the metallic plates C or C, C provided with the
carriers or guides E holding the square bolt F.
The terminal end of the bolt F has a slot H and a stud or peg I.
Jis a cam having a turned up edge or flange K which engages within the
slot H.
The stud or peg 1 or its equivalent engages against the inner surface of the
Bauge Kand the end M of the bolt F engages against the outer surface of the
flange K.
The can which is shown separately at Figure 5 is pivoted to the plate C by
means of the screw N and can be moved in the direction of the arrows by means
of the handle or lever O, or in cases where the bolt is placed in a high position on
the door the cam may be operated by a hook engaging in the hole S of the handle
or lever.
When the bolt is in its fastened position as shown at Figures 2, 3, and 4, the stud
or peg I rests and is locked in the recess P of the cam the bolt is prevented from
sliding downwards by the end of the bolt M butting against the outer surface of
the flange K.
When the bolt is, withdrawn from the staple box D the lover O is pressed
downwards, the end of the bolt M and the stud I following the curvature of the
cam.
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
