Year: 1868

page_text: LETTERS PATENT to Louis Pfeiffer, of No. 2, Walbrook Buildings,
in the City of London, Merchant, for the Invention of "AN:
IMPROVED FASTENING OR LOCK POR BAGS AND OTHER SIMILAR ARTICLES."
A communication from abroad by Auguste Schubeus, of Paris,,
France
PROVISIONAL SPECIFICATION left by the said Louis Pfeiffer at the.
Office of the Commissioners of Patents,, with his Petition, on the
30th November 1868,
I, LOUIS PFEIFFER, of No. 2, Walbrook Buildings, in the City of
London, Merchant, do hereby declare the nature of the said Invention
for "AN IMPROVED FASTENING OR LOCK FOR BAGS AND OTHER SIMILAR ARTICLES,"
(being a communication to me from abroad by Auguste Schubeus, of
Paris, France,) to be as follows:-
In the interior of a casing attached to one side of the frame of the
bag or other similar article are placed two metal slides (each having an
angular end where they meet in the centre of the casing), which are
pressed together by means of springs. At the back of each of these

page_text: slides is fixed a projection having attached thereto a pin, and in the
casing are fixed two pins running at right angles to the former. The
springs are placed on the pins (fixed to the projections and slides), and
when a knob or stud (which projects through the exterior of the framing
of the bag) is pressed upon the angular ends of the slides, they are
forced apart and the springs are pressed against the pins fitted in the
casing, but immediately the knob is released of the pressure the reaction
of the springs forces back the slides to their former positions. In the
slides are formed holes which confine or take hold of the catches or
hooks on the other portion of the frame when the sides of the framing
(or opening part of bag) are pressed together. When the knob or stud
is pressed upon the angular ends of the slides they are forced apart and
allow of the introduction of the catches or hooks (the sides of the open-
ing of the bag being pressed together) through the holes in the slides
above mentioned (also through corresponding holes formed in the casing);
but as soon as the knob is released of the pressure the slides are pressed
together by the springs and the catches or hooks are caught in the holes
(in the slides), thereby locking the bag. As a further security when the
bag is elosed and fastened to prevent its being unfastened a suitable casing
is fixed outside the framing of the bag, within which is a bolt, which
bolt on being pushed by the key under the knob, or stud prevents the
latter being pushed down and so opening the bag. Both these casings
are secured to, the frame of the bag by screws or other equivalent
means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, a
filed by the said Louis Pfeiffer in the Great Seal Patent Office
on the 29th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
PFEIFFER, of No. 2, Walbrook Buildings, in the City of London,
Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of November, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Louis Pfeiffer, Her special-

page_text: licence that I, the said Louis Pfeiffer, my executors, administrators, and
assigns, or such others as I, the said Louis Pfeiffer, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
FASTENING OR LOCK FOR BAGS AND OTHER SIMILAR ARTICLES," (a communica-
tion to me from abroad by Auguste Schubeus, of Paris, France,) upon
the condition (amongst others) that I, the said Louis Pfeiffer, my
executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Louis Pfeiffer, do hereby declare
the nature of the said Invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement in writing, and on reference being had to the accom-
panying Sheet of Drawings, that is to say :-
In the interior of a casing attached to one side of the frame of a bag
or other similar article are placed two metal slides (each having an
angular end where they meet in the centre of the casing), which are
pressed together by means of springs. At the back of each of these
slides is fixed a projection having attached thereto a pin, and in the
casing are fixed two pins running at right angles to the former. The
springs are placed on the pins (fixed to the projections and slides) and
when a knob or stud (which projects through the exterior of the framing
of the bag) is pressed upon the angular ends of the slides they are forced
apart and the springs are pressed against the pins fitted in the casing,
but immediately the knob is released of the pressure the reaction of the
springs force back the slides to their former positions. In the slides are
formed holes which confine or take hold of the catches or hooks on the
other portion of the frame when the sides of the framing (or opening.
part of bag) are pressed together. When the knob or stud is pressed
upon the angular ends of the slides they are forced apart and allow of

page_text: the introduction of the catches or hooks (the sides of the opening of the
bag being pressed together) through the holes in the slides above
mentioned (also through corresponding holes formed in the casing), but
as soon as the knob is released of the pressure the slides are pressed
together by the springs and the catches or hooks are caught in the holes
(in the slides), thereby locking the bag. As a further security when the
bag is closed and fastened to prevent its being unfastened a suitable
casing is fixed outside the framing of the bag, within which is a bolt,
which bolt on being pushed by the key under the knob or stud prevents
the latter being pushed down and so opening the bag. Both these
casings are secured to the frame of the bag by screws or other equivalent
means.
Such being the nature and object of the said Invention for "An
Improved Fastening or Lock for Bags and other similar Articles," I will
now proceed to describe more in detail the manner in which the same is
to be or may be performed or carried into practical effect, and in order
that the same may be distinctly understood I have annexed hereunto a
Sheet of Drawings illustrative thereof, and have marked the same with
figures and letters of reference corresponding with those in the following
explanation thereof, that is to say:-
Figure 1 on the accompanying Sheet of Drawings is an elevation of
the frame of the opening part of a bag (showing part of it closed and
part opened) with the improved fastening or lock attached; Figure 2 is
a side elevation of the same, a section through A, B, Figure 1; Figure 3
is a front elevation of the fastening or lock, the front plate of the lower
casing being removed (the holes in the same being represented by the.
red lines) to show the internal arrangement thereof; Figure 4 is a back
elevation of part of the same, also showing the internal arrangement;
Figure 5 is a plan of the same; Figure 6 is a plan of the upper casing of
the fastening or lock; Figure 7 is a plan of the internal arrangement of
the same; Figure 8 is an end elevation illustrating the form of the lower
casing; Figure 9 is a front elevation of the "pusher" or knob for
operating the fastening; Figure 10. is a side elevation of the same;
Figure 11 is a plan of one of the catches or hooks, also showing the
manner in which it is held by the slides.
a is the casing (screwed or otherwise attached to one side of the
opening part of the frame of a bag or other similar article), in which two

page_text: slides 6 are placed; these slides are pressed together or kept in contact
by the two springs c (Figure 4); d. (Figure 4) represents two pro-
jections fixed to the back of each of the slides b, which projections
have attached or fixed to them two pins e, and in the casing a are
fixed two other pins f, running at right angles to the former. The
springs c are placed on the pins e, and when the knob or pusher g is
pressed upon the angular ends h of the slides b they are forced apart, the
springs being pressed against the pins f, but immediately the "pusher"
is released of the pressure the force of the springs c push back the slides
to their former positions (Figure 4). Holes i are made in the slides to
confine or take hold of catches or hooks j (on the other portion of the
framing of the bag) when the sides of the opening part of the bag are
pressed together. The pusher g on being pressed to the position shewn
in blue lines in (Figure 3) forces back the slides to the positions also
shown in blue lines, making the holes i in the same correspond with
holes m in the casing (represented in Figure 3 in red lines on account of
the front plate being removed); this allows merely of the introduction of
the catches or hooks j (the sides of the bag being pressed) through the
holes both in the slides and in the casing, but as soon as the pusher is
released of the pressure the slides bare forced together by the springs c,
and the catches or hooks are caught in the holes i in the slides, by this
means fastening or locking the bag. In order to prevent the bag from
becoming opened after being closed, and as a further security against the
same being unfastened, a suitable casing k, through which the ".
"pusher"
passes, is screwed or otherwise fixed outside the framing of the bag
(shown in Figure 1) or other article, within which is a bolt l, which bolt
'on being pushed by the key under the knob n (in the position shown in
red lines in Figure 7) of the "pusher" effectually prevents the same
being pushed down and the bag being opened. A spring is placed
inside the upper case to force the pusher up should it by any means
become fixed.
Having now described the nature and object of the said Invention for
"An Improved Fastening or Lock for Bags and other similar Articles,"
together with the manner in which the same is to be or may be performed
or carried into practical effect, I would remark in conclusion that I claim
as the Invention (communicated to me by the above-named Auguste
Schubeus), the improved arrangement of mechanism to be attached or
fixed to bags or other similar articles constituting an improved fastening
or lock for the same, as herein-before described or set forth, and as illus-

page_text: trated on the accompanying Sheet of Drawings, or any mere modification
thereof acting in the same or a similar manner.
In witness whereof, I, the said Louis Pfeiffer, have hereunto set
my hand and seal, this Twenty-fourth day of May, in the year
of our Lord One thousand eight hundred and sixty-nine.
LOUIS PFEIFFER. (L.S.)
