AN ADJUSTABLE LOCK OR FASTENING
Year: 1884

page_text: 1, FREDERIC EDWARD TAYLOR 115 Newhall Street Birmingham, in the County
of Warwick Clerk, do hereby declare the nature of the above named Invention for
AN ADJUSTABLE LOCK OR FASTENING, to be as follows:-
My Invention relates to an 'expanding lock or fastening,' for the greater
convenience of those using music carriers folios, albums, books, purses, or cases of
any kind; and in keeping the same securely closed.
It consists of a central box, in one side of which a piece of metal slides either in
or out a certain distance. This metal slide is hinged on a flange, which in its turn
is fastened to the article on which the expanding lock or fastening is to be used.
The expansion is caused by a spring, or springs, placed in the central box, on, or
under, the metal slide. When the slide is drawn out, the spring or springs are
contracted, on releasing it, the springs expand, forcing the slide back into the box.
On the other side of the central box, either just underneath, or at the side, is a slot
to receive the catch on the hasp when it is fastened. The hasp is a flange made to
correspond to the flange on which the slide is hinged. Inside the central box on the
slot side is a bolt and pusher, which latter projects beyond the surface of the box.
Both are controlled by a spring. When this pusher is pressed, or pushed along the
spring contracts, and the bolt is driven along leaving the slot hole clear. This
releases the catch, and the lock is unfastened. The pusher can work either on the
top, or on the sides, just as required. If preferred the expanding lock can be mado,
by removing the small spring bolt and pusher from the central box, and fixing
them in a box on the outer end of the slide, and reversing the positions of the slide
and hasp flanges.

page_text: I, FREDERIC EDWARD TAYLOR 115, Newhall Street, Birmingham, in the County
of Warwick, Clerk, do hereby declare the nature of my Invention for AN
ADJUSTABLE LOCK OR FASTENING and in what manner the saine is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The adjustable lock or fastening is mado of metal, and consists of a central
box A. Fig. 1 which contains the principal parts of this Invention. Along one side
of tho box A a slit B. Fig. 2. is left open to admit a piece of metal C. Fig. 2. which
is generally flat, and can be drawn partly out, or pushed partly in as required. It
cannot be drawn quite out, owing to the insido edge being rased D. Fig. 3. and
this with the presence of two springs S. Fig. 4. which prevent the raised edge from
reaching the side, will not admit of its entirely passing through the slit B. The
raised edge D also steadies the slide C causing it to work evenly. The outside
edge of the slide C is hinged on to a metal flange E the said flange being the part
which is fastened to the article on which the lock is to be used. Inside the box A
Fig. 4. placed under the slido C between the inside raised edge D and the side of
the box A which contains the slit B are either two spiral springs, S. or hair
springs S. bent in a V form, divided by a partition F, fixed on the bottom cover
plate of the box A. When the slide C is drawn out the partition F allows the
raised edge D to pass it, by passing through an opening "G, made in the raised
edge D.
When the slide C is pulled out, the springs S. are contracted, but on
releasing the slide C, the springs expand to their former position, and force tho
slide C back inside the box A. This shews the expanding action of the lock. In
the central box A, in the side opposite to that which I have been describing, is a
slot, or hole, H. Fig. 5, made to receive the catch I. Fig. 6. which catch is fixed on
the hasp or flange K. Fig. 6. and this in its turn is fastened to the article on which
the lock is to be used. .Inside the central box A, against the slot side, is a space L.
partitioned off, containing a spring M, either spiral, or hair spring bent, and a
inetal slide N, which acts as pusher and bolt at one and the same time. Tho
narrow end of this piece of metal N, projects through the side of the box A, and is
called the pusher P. Fig. 4. A slot is cut in the piece of metal N. and the edge of
this slot forms the part in the bolt that secures the catch I, when it is in the two
slots. The spring M is placed at the back of the bolt and pusher N. and as tho
two hardly fill the partition L lengthways, the spring M pushes the bolt and
pusher as far out as it can, the edge of the slot in the bolt coming half across tho
slot H. Fig. 5. When the catch I is pressed into the slot H, the bolt is forced back,
but resumes its old position, as soon as the catch is in, holding it (the catch) quito
tight. The catch I. is only released by pressing the pusher in, which of course
forces the spring back, and the edge of the bolt hole, away from the slot H. This
description shews the locking action of the lock. One form of making the
expanding lock different to above, is this; to remove the locking action entire, and
fix it on the slide C, where the flango E is hinged. This flange would be taken
away, and hinged on the central box A, on the side from which the locking action
was removed. A slot would be made in the box containing the locking action,
to receive the catch on the hasp. Thus the two boxes would lie side by side
and would only be separated a short distance from each other, when the expanding
action was in use, resuming their old positions close together when the expanding
action was at rest. The shape of the expanding lock or fastening is liable to

page_text: alteration, and I do not bind myself rigidly to any of the particular forms herein
described. For instance; in place of the slide Ca wire might be bent in an
oblong or square shape, working through two holes in the box A, one side of the
wiro being hinged on to the flange, as the slide C is. If this form were used, the
spring or springs would be placed, not on, but between the sliding wire, unless
spiral springs wero utilized. For this form vide Fig. 7. Either more or less than
two springs can be used, of any shape, in box A. and partition F can be done away
with if desired, so as to allow the springs or spring to work in any direction
between the raised edge D, and the sides of the box A. One or more springs can
be placed in partition Lif wished for. If necessary a pin or stop will be placed in
box A to prevent the raised edge D being pulled out beyond a certain distance, so
that the spring or springs S. may not be compressed beyond their strength, and so
become liable to break. The lock or fastening can be used on music or drawing
folios music carriers, albums, books, purses, or cases of any kind that are used as
covers, also on any article whatsoever, such as cricket belts, braces, etc., on which
it can be used for purposes of fastening or connecting two things or more together,
by simply altering the form of the flanges E and K. If used on a music folio the
two flanges would be fixed one on each side, and the folio could then be fastened
securely-being undone by pressing the pusher P. It is intended to make it (the
lock) and put it together entirely by the aid of tools, without the use of solder,
screws, or rivets of any kind, if they can be dispensed with, which is probable.
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
(i) The use of a spring or springs in a lock, so arranged that the distance
between the parts for attachment to the article to be locked may be variable,
substantially as described.
(ii) A locking device operated by pressure exerted upon a pin or knob projecting
through the side of the case against the resistance of a spring or springs.
(iii) The combination of an adjustable lock and locking device as herein before
described, and applicable to music or drawing folios, albums, and similar articles.
