Year: 1876

page_text: LETTERS PATENT to Julius Müller, of the Firm of Müller and Hilpert, of
Berlin, Prussia, for the Invention of "A NEW OR IMPROVED CLASP OR CLOSURE
FOR ALBUMS, BOOKS, AND OTHER ARTICLES."
Sealed the 6th April 1877, and dated the 30th October 1876.
PROVISIONAL SPECIFICATION left by the said Julius Müller at the Office of
the Commissioners of Patents on the 30th October 1876.
"A NEW
JULIUS MÜLLER, of the Firm of Müller and Hilpert, of Berlin, Prussia.
OR IMPROVED CLASP OR CLOSURE FOR ALBUMS, BOOKS, AND OTHER ARTICLES."
This closure or clasp consists mainly of two parts sliding one in the other.
One part is hinged to the book cover and slides in the other or box-like part,
which is made to hasp on to the other book cover. In the latter or box part, but
underneath the first-named part there is a "bolt," having slots for sliding on two
pegs rivetted to the box-like part; the latter and the "bolt" are held together by
two spiral springs; the bolt is held in its place by means of an ordinary tumbler
and lock spring. The bolt is also fitted with two pegs, which when the clasp is
locked by means of a key pass behind two corresponding bars or wards. To open
the book the box-shaped part is drawn so far out that the usual hooks formed
thereon are drawn off, the usual pegs or bar on the book cover and the whole clasp
can then be thrown back. If the bolt be pushed so far that the two pegs
catch behind the bars or wards, then the outer enclosing part cannot be drawn so
high that the hook leaves the bar or pegs on the book cover, whereby the closure of
the book is secured.
The second or modified arrangement only serves to hold books together, but not
to lock them. It also consists of two parts; the one is hinged to one book cover,
while the other with a hook or hasp catches over a bar or pegs of the other book
cover. The two parts are also in this case drawn together by two spiral springs.
By drawing up the outer part the hasp is disconnected from the bar or pegs, and the
clasp can then be thrown back.

OR IMPROVED CLASP OR CLOSURE FOR ALBUMS, BOOKS, AND OTHER ARTICLES."
This closure or clasp consists mainly of two parts sliding one in the other, and is
illustrated by the accompanying set of Drawings, of which,
Figure 1 is a view showing the interior of the clasp in the open position, and
Figure 1 a similar view of the same in the closed position; Figure 2 is a side eleva-
tion of same with the box or album covers in section.
Figures 3 and 3ª are respectively front view in the open and closed position
of a clasp according to a modified arrangement; Figure 4 is a side elevation of
same.

are
One part a is hinged to the book cover and slides in the other or box-like part b,
which is made to hasp on to the other book cover. In the latter or box part, but
underneath the first-named part a there is a "bolt" c, having slots for sliding on
two pegs d and c rivetted to the box-like part b; the latter and the "bolt
C
held together by two spiral springs m, ml; the bolt c is held in its place by means
of an ordinary tumbler and lock spring. The bolt c is also fitted with two
pegs 1, h, which when the clasp is locked by means of a key pass behind two
corresponding bars or wards i, . To open the book the box-shaped part bis
drawn so far out that the usual hooks formed thereon are drawn off the usual
pegs or bar n on the book cover, and the whole clasp can then be thrown back.
If the bolt c be pushed so far that the two pegs h, h, catch behind the bars or
wards, , then the outer enclosing part 6 cannot be drawn so high that the
hook leaves the bar or pegs n on the book cover, whereby the closure of the book
is secured.
The second or modified arrangement only serves to hold books together, but not
to lock them. It also consists of two parts a and b; the one a is hinged to one
book cover, while the other b with a hook or hasp catches over a bar or peg 1 of
the other book cover. The two parts are also in this case drawn together by two
spiral springs m, m³. By drawing up the outer part the hasp is disconnected
from the bar or pegs 1, and the clasp can then be thrown back.
And having thus fully described the nature of this Invention, I declare that I
claim the combination of the movable parts a and b and the spiral springs m, m³,
with or without the bolt e and locking arrangement, all substantially as and for the
purposes set forth.
In witness whereof, I, the said Julius Müller, have hereunto set my hand
and scal, this Twenty-third day of April, in the year of our Lord One
thousand eight hundred and seventy-seven.
