improved in the Construction of BOILS OF Bars for Doors,
Gates, and the like.
We ALLAN EDMONDSON, Cabinet Maker, JOHN BENJAMIN MOORHOUSE, Ironinonger,
and THOMAS ABRAHAM PROCTER, Cabinet Makor, all of Skipton-in-Craven, Yorkshire,
do hereby declare the nature of this invention to be as follows :-
This invention consists of improvements in the construction of bolts or hars for
doors, etc., by which the same are enabled to be locked or held more securely in
position when in or out of actual use.
This is accomplished by forming in the bolt or bar a suitably shaped opening into
which is inserted a pin, the said pin being mounted rigidly on an excentric or swape
which is carried in a suitable manner by the supports that carry the bolt or bar.
To this excentric is attached a suitably shaped thumb-and-finger-piece, which when
turned moves the bolt outwardly or inwardly as the case may be, as will readily
be understood. And when the extreme point of its movement, in either direction, is
reached, the pin in the excentric will have come to the "dead centre" position relative
with the axis of the bolt or bar, and so hold the said bolt or bar rigidly in this position
until the said pin is again turned.
Of course instead of the bolt being formed for the reception of a pin, it might be
formed to receive the excentric or swape itself and in this manner dispense with the
said pin.
Since the foregoing method of construction does not interfere to any great extent
with the size of the bolt, it will readily be seen that not only the common kind of
bolt may be thus constructed, but others, such as "flush" bolts, heavy door bolts, etc.,
may be made according to the present improvements.

page_text: We, ALLAN EDMONDSON, Cabinet Maker, JOHN BENJAMIN MOORHOUSE, Ironmonger,
and THOMAS ABRAHAM PROCTER, Cabinet Maker, all of Skipton-in-Craven, Yorkshire
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 :-
That is to say It consists of improvements in the construction of bolts or bars for
doors etc., by which same are enabled to be locked or held more securely in position
when in or out of actual use, and in order that this said invention may be more
readily understood, hereunto is appended a sheet of drawings illustrative thereof, the
same bearing figures and letters of reference used in the following description.
Fig. 1 is a side view of that side of the bolt that fits to the door when said bolt is
attached. Fig. 2 is an end view of Fig. 1. Fig. 3 is a part sectional view of Fig. 1
as seen from above. Figs. 4 and 5 illustrates a modified form of bolt, applicable for
heavy doors, gute etc.
The object above set forth is attained by forming a suitably shaped opening a in the
bolt or bar b, said opening a being for the reception of the pin c which is rigidly
attached to the eccentric or swape d to which is attached the thumb-and-finger
piece e all said parts b, c, d and e being carried by the framing f. It will readily be
understood that when the thumb-and-finger piece e is rotated, the bolt 6 will be moved
outwardly or inwardly as the case may be, by the pin c operating same, and that when
the extreme point of its movement in either direction (the outward one being
illustrated by figs. 1 and 3), is reached, the pin c relatively with the centre or axis of
the swape d, will have come to the "dead" centre position, and so will hold the boit b
rigidly in this position until said pin c is again turned.
Of course instead of the bolt being formed for the reception of the pin c it might
be formed as shewn by b figs. 4 and 5 to receive the eccentric d' in which case it is
more appropriate for heavy doors &c.
Since the above described method of construction does not interfere to any great
extent with the size of the bolt, it will be readily seen that not only the common kinds
of bolts may be thus constructed, but others such as those known by the name of "flush
bolts" may be made according to this invention.

page_text: Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1. The combination of the bolt with the pin c, the swaped and the thumb-and-finger
piece e all arranged to operate substantially as and for the purpose specified.
2. The combination with a bolt for a door or gate, of an eccentric arranged to
operate same substantially in the manner and for the purpose specified.
