PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Flush Bolts and Barrel Bolts.
ERNEST VALENTINE ORFORD 581 Broad Street Birmingham Brassfounder
do hereby declare the nature of this invention to be as follows:-
My improvements consist in making a flush bolt either right hand or left that
you can readily manipulate with the finger and thumb without the risk of breaking
your nails as in the ordinary cast bolt with a sunk centre and also make it self-
locking and do away with the spring.
In order to do this I take a piece of strip metal and raise it acrossways with two
deep grooves in about half an inch apart with a hole pierced crossways through the
grooves and lying flush with the face of the bolt on the under side. This hole
terminating at the top of the bolt frame. Into this said hole the bolt is slid and
works therein and a short arm is there riveted, or screwed at right angles into the
bolt for the purpose of raising or lowering the same. This arm and bolt together
revolve in the above hole in the frame and in use the arm on being turned stands
out at right angles from the frame so as to be able to be readily taken hold of and
on being pushed either to the right or left when opposite the aforementioned
grooves in the frame falls therein flush and will not allow the bolt to move up and
down till again drawn round. This arm or handle is made a little longer than the
width of the frame so as to stand a shade over the thickness of the door so as to
allow of its being readily manipulated. I can also make this into a barrel bolt by
turning it over on to its reverse side and screwing it on with its flush side against
the door.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Flush Bolts and Barrel Bolts.
I, ERNEST VALENTINE ORFORD, of 58 Broad Street, Birmingham Brass-
founder, do hereby declare the nature of my said invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention for "Improvements in the manufacture of "flush bolts" and
"barrel bolts" consists in the mode of construction and the adaptability arising
therefrom, to such purposes as both of this class may be employed.
For a "flush bolt" constructed according to my invention I shape or configurate
from metal, if the strip, of required width, and cut to a required length, forming a
plate, by means of tools I depress crosswise two grooves or channels, of a U shape,
upper and lower, the intervening space between these grooves or channels is
provided with a slot; each side of each groove or channel has a pierced hole, of a
size sufficient to receive the cylindrical bolt, the lower end of plate is bent to an
angle inwards and is dished and pierced to guide the bolt, this bolt is provided with
a short arm or lever by means of which the said bolt is actuated by passing through
the slot above named, and engaging by a right or left movement in either of
grooves or channels according whether the bolting or fastening effected. The
bolt and parts sustaining same are inlet to its purpose, and fixed in the usual
manner by screws passing through counter-sunk holes, at each end.
When in application the short arm or lever slightly projects over its fitting, to
Pics S/1

page_text: enable its being actuated with greater facility. The position of this "flush bolt"
may be either vertical or horizontal according to its requirement.
«
For a barrel bolt" I reverse the position (that is to say) the depressed parts
forming grooves or channels and carrying the bolt, and which as above described as
inlet, and would be the back, is now brought to form the front, and can be secured
to any surface, and to such purpose as "barrel bolts" are employed, it is applicable
to a right or left movement.

Having thus specified the object and nature of this my said invention for
Improvements in the manufacture of "flush bolts" and "barrel bolts' its
description will be proceeded with in reference to the accompanying drawings (that
is to say)
Fig. 1, is the blank from a strip of metal forming a plate, for a "flush bolt” or
first process.
Fig. 2, is a back view elevation of said blank or plate with grooves or channels
depressed crosswise, pierced, and the bolt fitted therein, with the short arm or lever
resting in the upper groove, which is the position of bolt when unemployed.
Fig. 3 is a side view elevation as Fig. 2.
Fig. 4 is a front view elevation as Figs. 2 and 3, with the short arm or lever
resting in the lower groove or channel, which is the position of bolt when employed.
Fig. 5, is the blank or first process from a strip of metal forming a plate for a
"barrel bolt."
Fig. 6, is a front view elevation of said blank or plate, the position of the grooves
or channels being reversed pierced, and the bolt fitted therein with the short arm or
lever resting on the stop-piece which is the position when the upper end of the bolt
is employed and the lower unemployed.
Fig. 7, is a side view elevation as Fig. 6.
Fig. 8, is a view as Fig. 6, but the lower part of the bolt employed and the upper
unemployed.
Fig. 9, shows a modification of the blank or plate as Fig. 1, and 5.
Fig. 10, a front view elevation, the grooves or channels are here dispensed with,
the intervening parts between the slots being raised sufficient for the bolt to move
therein, the bolt here is unemployed.
Fig. 11, is a side elevation as Fig. 10, but the bolt employed.
Fig. 12, is an end view as Figs. 10 and 11.
Fig. 13, is a front elevation showing grooves or channels partly across, and bolt
employed.
Fig. 14, a side elevation of same but the bolt unemployed.
Fig. 15, is a view shewing how blanks or plates may be formed by rolling.
Fig. 16, is a departure in configuration or outline.
The same letters of reference upon the several figures indicate like or corre-
sponding parts.
a, is the blank or plate, b, b, are the grooves or channels, c is the slot d, d, d, d, are
the holes through which the bolt e, slides and revolves, a', is the angular end, dished
at, and pierced at d', g is the short arm or lever, h is the stop piece formed by
partly piercing and bending upward, clearly shewn in Figs. 7, and 14, i, i, i, i, are
the slots, the raised parts in which e, moves o, o, are countersunk holes, for
screwing or fixing to its purpose.
It will be perceived that the aim and object of my invention is to construct bolts
of the class enumerated from sheet metal, thus reducing the weight and process
known as dressing, as when required from wrought or cast work, further, goods are
always more dependable and presentable made as above set forth.
The said flush

or "barrel bolts" according to my invention would be from a
strip of metal of a required width and cut off a required length, or by the employ-
ment of tools, cut out or pierced, of any shape or configuration in outline in either
case the parts for carrying the bolt would be produced by raising tools," unless!
employ a strip the raised parts then would be effected by passing the same through
a pair of rolls.

page_text: The above being my invention I wish to say that I do not confine myself to the
precise details herein given and set forth, bat that I hold myself at liberty to alter
or modify the same without departing essentially from my said invention.
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 :-
1st. The construction of a "flush bolt" from sheet metal provided with grooves
or channels, crosswise, for receiving or carrying the bolt, with arm or lever for
actuating, and the securing of same when employed, or otherwise, by engaging in
said grooves or channels, either to the right or left, substantially as and for the
purposes herein before described and set forth.
2nd. The construction of a "barrel bolt" from sheet metal, provided with
grooves or channels, crosswise, for receiving or carrying the bolt, with arm or lever
for actuating, and the securing of same when employed or otherwise by engaging
with the stop piece" either to the right or left, substantially as and for the
purposes herein before described and set forth.
3rd. The general construction combination and arrangement of parts, substan-
tially as herein before described in the foregoing Specification, and shewn on the
accompanying sheet of drawings.
