Improvements in the Manufacture of Barrel Bolts.
I THOMAS SANDERS of St. Mary Street Ladywood Birmingham in the County
of Warwick Brassfounder, do hereby declare the nature of this invention.to be as
follows
:-
This invention relates to that kind of barrel bolt in which the barrel is made out of
two pieces of metal, the top part being about semicircular for containing the bolt and
the bottom part being soldered on to it to complete the circular tube or barrel in which
the bolt works.
The object is to reduce the cost of manufacture and to make the bolt more
ornamental.
The top part of the barrel has flanges at the bottom for screwing on to the door
and is slotted at the top in the ordinary manner for the pin of the bolt to work in.
For the purpose of placing the bottom part of the barrel in position and fixing it,
the top part of the barrel is rebated at about the angle between the flange and the
barrel and so forms a kind of groove or angle for the bottom part to fit in.
Thus it will be perceived that the chief novelty of this invention is the rebate or
angle which acts as a guide for placing the under portion of the barrel in position for
soldering.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Barrel Bolts.
I, THOMAS SANDERS of St. Mary Street, Ladywood, Birmingham in the County
of Warwick, Brassfounder, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement and illustrated by the accompanying
drawings
Fig. 1 of the accompanying drawings is a transverse section of the bolt and Fig. 2
a plan; the detail parts are referred to alphabetically.
This invention relates to that kind of barrel bolt in which the barrel is made out of
two pieces of metal, the top part being about semicircular for containing the bolt,
and the bottom part being soldered on to it to complete the circular tube or barrel in
which the bolt works.
The object is to reduce the cost of manufacture and to make the bolt more
ornamental.
The top part of the barrel has flanges at the bottom at A for screwing on to the
door and is slotted at the top at B in the ordinary manner for the pin of the bolt to
work in.
For the purpose of placing the bottom part of the barrel in position and fixing it,
the top part of the barrel is rebated at about the angle between the flange and the
barrel at C and so forms a kind of groove or angle for the bottom part D to fit in.
Thus it will be perceived that the novelty of this invention consists in making the
circular barrel in two pieces the top one being rebated to act as a guide for placing
the under portion of the barrel (which completes the circle) in position for soldering.
There may be a spring in the underside of the barrel at E for the purpose of keeping
the bolt in position.

page_text: · 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 :-
1. A barrel bolt of which the circular barrel is made in two parts as hereinbefore
described and illustrated by the accompanying drawings.
2. The rebate or angle at C acting as a guide for fixing the underside of the barrel
in position for soldering substantially as hereinbefore described and illustrated by the
accompanying drawings.
