IMPROVEMENTS IN LOCKS
Year: 1885

page_text: I, JAMES BUCHANAN of 38 and 42 Old Wynd, Glasgow, in the County of
Lanark, North Britain, Lock and Hinge Makers do hereby declare the nature of
the said invention for "IMPROVEMENTS IN LOCKS to be as follows:-
This Invention, which relates to improvements in Locks, has reference to that
class of locks commonly known as "stock locks," "draw-back chamber locks" and
other locks of a like class, in which the stock usually consists of rectangular slab
of wood with a recessed portion to receive the working parts. In the improved
locks the spring and "player" are formed in one piece and are fixed in the stock
by the upper end of the spring being secured in a slot formed in the stock or by
a pin fixed in the stock of the lock. The eye of the combined spring and "player"
being held upon a pin also fixed in the stock, or the spring and "player" may be
made in two pieces in which case the spring is firmly fixed at its upper end, 'to
the stock and presses' down upon the "player." The spring and player according
to either mode of construction are kept in their places in the stock of the lock by
one or more flat plates covering the recess in the stock, the said plates being
preferably of sheet iron and are secured by nails or screws to the solid'or outer
part of the stock of the lock.

I, JAMES BUCHANAN of 38 and 42 Old Wynd, Glasgow, in the County of
Lanark, North Britain, Lock and Hinge Maker do hereby declare the nature of
my invention for IMPROVEMENTS IN LOCKS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My Invention, which relates to improvements in locks, has reference to that
class of locks commonly known as stock locks, draw-back chamber locks and other
locks of a like class. In the improved locks a spring and player formed in one
piece are used and they are fixed in the stock by the upper end of the spring
being secured in a slot or by a pin fixed in the stock of the lock. The eye of
the combined spring and player is held upon a pin also fixed in the stock, or the
spring and player, may be made in two pieces, in which case, the spring is firmly
fixed at its upper end and presses down upon the player. The spring and
player according to either mode of construction are kept in their places in the
stock of the lock by one or more flat plates secured by nails or screws fitted to the
stock of the lock.
In order that my said Invention may be properly understood and readily carried
into effect, I will now proceed to describe the drawings hereunto annexed.
Figure 1, is a front elevation of one form of lock constructed according to my
present Invention.
Figure 2, is a front elevation of the same with certain plates, which are herein-
after described, removed.
Figure 3, is a similar view of the same with the said plates and the bolt
removed.
Figure 4, is an end elevation of the same.
Figures 5 and 6, are transverse sections of the same taken respectively on the
lines A. B. and C. D. Figure 1.
Figure 7, is a horizontal section of the same taken on the line E. F. Figure 1.
Figure 8, is a view similar. to Figure 3,' of another form of lock constructed
according to my-present Invention. -
In the lock which I have represented at Figures 1 to 7 inclusive, the stock A, is
formed of wood, and as shewn more particularly at Figures 2, 3, 5, 6 and 7, the
said stock is recessed out to receive the bolt B, and other working parts. The
bolt B, is formed with the recesses a, and b, (Figure 2) with the recess a, of which
the end c, of the player C, engages when the said bolt B, is in its locked position
whilst the end c, of said player engages with the recess b, when the bolt B is in its
unlocked position. The player C, is formed in one with the spring D, the end
of which is preferably doubled and secured in a recess formed in the stock A, that
is to say, in the manner indicated at Figures 1, 2 and 3 of the annexed drawings.
This combined spring and player is further supported by and upon the pin d, which
is preferably secured in the stock A, in the manner represented more particularly
at Figures 6 and 7, that is to say, by having its fang e, driven thereinto and
" clinched at the back of the said stock. The adjacent and of the bolt B, is
"
T-

page_text: recessed out so as to clear the pin d, and the said bolt is further provided at its
underside with the recess f, of proportions such as enable the end o, of the player
to be raised by the key out of the recesses a, and b, so that, by the further turning
of the said key the bolt may be moved backwards or forwards as may be
required. The pin 9, is that upon which the barrel of the key caused to pivot
and this pin secures the plate h, in position and is itself held in position in &
manner similar to that herein before described with reference to the pin d. Upon
the plate h, any desired projections i, or wards may be secured. The bolt B, and
all other working parts of the lock are maintained in their proper relative positions
by means of the plates j, k and 1, the plate j, of which is formed with an opening
in and through which the bolt is capable of being moved as indicated more
particularly at Figure 4, and the plate k, is formed with an opening for the
insertion, into the lock, of the key while all the said plates j, k, and I, are secured
to the stock by the nails m, or screws or their equivalents.
In the lock represented in part at Figure 8, of the annexed drawings, the
player n, is formed independently of the spring o, and is pivoted upon the pin d.
The said spring o, is held in a recess in the stock A, in a manner similar to that
herein before described with reference to the spring D, represented at Figures 1, 2, 3
and 5, and tends to press the player n, into the position indicated at Figure 8.
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
First. The improvements in locks consisting of the player C, formed in one piece
with the spring D, and supported in a recess formed in the stock A, and upon the
pin d, all substantially as and operating in the manner berein before set forth with
reference to Figures 1 to 7 (inclusive) of the annexed drawings.
Second. The improvements in locks consisting of the spring o, supported in a
recess formed in the stock A, and exerting its pressure upon the player n, near the
point on which it is pivoted on the pin d, all substantially as and operating in the
manner herein before set forth with reference more particularly to Figure 8 of the
annexed drawings.
