Year: 1879

page_text: LETTERS PATENT to Richard Samuel Charles Jelley and Robert Canning
Jones, trading as Jelley, Son, and Jones, of Blackfriars Road, in the County
of Surrey, for the Invention of "IMPROVEMENTS IN LOCKS OR FASTENINGS."
Sealed the 9th September 1879, and dated the 11th March 1879.
PROVISIONAL SPECIFICATION left by the said Richard Samuel Charles
Jelley and Robert Canning Jones at the Office of the Commissioners of Patents
on the 11th March 1879.
RICHARD SAMUEL CHARLES JELLEY and ROBERT CANNING JONES, trading as
Jelley, Son, and Jones, of Blackfriars Road, in the County of Surrey. "IMPROVE-
MENTS IN LOCKS OR FASTENINGS."
Our Invention relates to improvements in that class of locks or fastenings for
railway carriages or other doors in which an eccentric bolt or catch is used, nade in
one piece with its follower in the form of a lever, and with a curved or eccentric
shaped upper edge.
It consists in arranging in contact with the curved or eccentric shaped upper
edge of the bolt or catch, an arm or lever hinged to the back of the box behind the
handle, pivot, or hinge of the bolt or catch; against this arm or lever takes the
outer end or nose of a second arm or lever hinged at the upper part of the box, and
actuated behind by a flat or other spring secured at the lower part of the box. The
outer end of the bolt or catch is formed with a bevilled lip or nose piece which,
when the bolt or catch is turned upward by its handle (or the lock unfastened), is
caught and held in that position by the bevilled outer end of a spring catch attached
at its inner end to the upper part of the back of the box.
From the outer bevilled end of this spring catch projects beyond the face of the
box a flanged piece or lip which upon closing the door to which the lock is attached
strikes against the rebated edge of the striking plate, and being thereby forced
backwards releases the bolt or catch, which is then thrown forwards and outwards
by the spring acting on it through the arms or levers, one of which is in contact
with its curved edge as before described..
'
By this means the handle of the lock or bolt remains in an upright position when
the bolt is held back by the spring catch, or the door unfastened, and assumes a
horizontal position when the bolt is released or the door fastened.

RICHARD SAMUEL CHARLES JELLEY and ROBERT CANNING JONES, trading as
Jelley, Son, and Jones, of Blackfriars Road, in the County of Surrey. "IMPROVE-
MENTS IN LOCKS OR FASTENINGS."
Our Invention relates to improvements in that class of locks or fastenings for
railway carriage or other doors in which an eccentric bolt or catch is used, made in
one piece with its follower in the form of a lever, and with a curved or eccentric
shaped upper edge.
It consists in arranging in contact with the curved or eccentric shaped upper edge
of the bolt or catch, an arm or lever against which takes the outer end or nose of a
second arm or lever actuated behind by a flat or other spring.
The outer end of the bolt or catch is formed with a bevilled lip or nose piece
which, when the bolt or catch is turned upward by its handle (or the lock "unfas-
tened "), is caught and held in that position by the bevilled outer end of a spring
catch, the upper part of this end projecting beyond the face of the box in a flanged
piece or lip, which upon closing the door to which the lock is attached strikes
against the rebated edge of the striking plate, and being thereby forced backwards
with the spring catch, releases the bolt or catch, which is then thrown forwards and
outwards by the flat or other spring acting on it through the arms or levers before
mentioned.
And in order that our said Invention may be well understood, we shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the accompanying Sheet of Drawings, like letters of reference indicating corresponding
parts in all the Figures.
Fig. 1 is a side elevation of one of our improved locks or fastenings with cover
plate removed, and Fig. 2 a front view thereof.
A represents an eccentric bolt or catch made in one piece with its follower, and
hinged or pivoted with its handle at a to the box B as shown. In contact with the
curved or eccentric shaped edge 6 of the bolt or catch A is the outer end of an arm
or lever C, hinged at c to the back of the box B, behind the handle pivot or hinge a;
against this arm or lever C takes the outer end or nose of a second arm or lever D,
hinged at d to the upper part of the box B, and actuated behind by a flat curved
spring E, secured at the lower part of the box B. The outer end of the bolt or
catch A is formed with a bevilled lip or nose piece e, which, when the bolt or
catch A is turned upwards by its handle (or the lock "unfastened "), forces back
and passes the bevilled outer end of a spring catch F, pivoted at its inner end to
the upper part of the box B, and operated by its spring G so that on the catch F
returning to its normal position the bolt or catch A is thereby caught and held in
the upward or unlocked position.
From the bevilled outer end of the spring catch F projects over the face of the
box B a flanged piece or lip g, the edge of which, upon closing the door to which
the lock or fastening is attached strikes against the rebated edge of the striking
plate H, see dotted lines Fig. 1, and being thereby forced back with the spring
catch F, releases the bolt or catch A, which is then thrown forwards and outwards
into the hasp or catch of the door by the force of the spring E acting upon it
through the arms or levers D and C, and the door is thereby automatically fastened.
By this means the handle of the bolt or catch A remains in an upright position
when the latter is held back by the spring catch F, or the door "unfastened," and
assumes a horizontal position when the bolt or catch A is released or the door
" fastened."
If preferred, a straight flat spring may be used for operating the bolt or catch A
in lieu of the curved spring E, as seen in Fig. 1.

page_text: Besides the simplicity and durability of this Invention it has the advantages that
when applied to a railway carriage door the latter may be closed automatically
without the necessity of turning the handle, but simply swinging the door to,
thereby saving time and trouble. Also, when the bolt or catch has been released,"
and the door securely fastened, it cannot become accidentally unfastened, which is
often the case with the fastenings in present use, and proves a fruitful source of
danger and annoyance.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider novel and original, and
therefore claim as the Invention secured to us by the hereinbefore in part recited
Letters Patent is,-
The application and use of an eccentric bolt or catch made in one piece with its
follower in combination with one or more arms or levers actuated by a flat or other
spring, and with a spring catch projecting at its outer end over the face of the box
to locks or fastenings substantially as hereinbefore described and illustrated by the
accompanying Drawing.
In witness whereof, we, the said Richard Samuel Charles Jelley and Robert
Canning Jones, have hereunto set our hands and seals, this Thirty-first
day of July, in the year of our Lord One thousand eight hundred and
seventy nine.
