Improvements in Hinge Fastenings for Tune Sheets, Jacquard
Cards, Belting, Writing Cases, Doors and the like,
We, CARL ALBERT ROEPKE and ROEPKE AND COMPANY LIMITED, of 33, Tib Street,
Manchester, in the County of Lancaster, Musical Instrument Manufacturers, do
hereby declare the nature of this invention to be as follows:-
"
This invention has for its object to provide a hinge like fastener for use in connec-
tion with tune sheets, jacquard cards, belting, writing cases, doors and the like,
which fastener can be readily disconnected and remains very secure when connected.
To this end my improved fastening consists of two plates one of which is formed
at the side with two eyes at a suitable distance apart from each other, and the
other plate with one eye open at its inner side. The said two eyes are fitted or formed
with a pin adapted to receive the eye of the other plate which is hooked onto the
Baid pin.
In order to prevent the plate with the one eye becoming unhooked, a tongue is
pivoted thereto, the inner end of which is adapted to enter the open side of its eye
and bear against the pin of the other plate.
To facilitate the setting of the said tongue its outer end is bent and may project
through a segmental slot formed in the said plate.

Improvements in Hinge Fastenings for Tune Sheets, Jacquard
Cards, Belting, Writing Oases, Doors and the like.
We, CARL ALBERT ROEPKE and ROEPKE AND COMPANY LIMITED, of 33, Tib Street,
Manchester, in the County of Lancaster, Musical Instrument Manufacturers, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Our invention relates to improvements in hinge fastenings for tune sheets,
jacquard cards, belting, writing cases, doors and the like and has for its object to
so form the said fastenings that they are extremely simple in construction, can be
very easily and quickly opened and are very secure when closed.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings, marked with letters of reference
indicating like parts in the various figures, and in which Figs. 1 & 3 are elevations

page_text: and Figs. 2 & 4 sectional end views of the fastening, Figs. 1 & 2 when closed and
Figs. 3 & 4 when open.
In carrying out our invention and referring to the figures generally our improved
fastening consists of two plates a & b, a of which is formed at the side with two
eyes a¹, a¹ which are at a suitable distance apart from each other, and the other
plate with one eye 61 formed in hook fashion open at its inner side. The said two
eyes are fitted or formed with a pin c adapted to receive the eye b¹ of the other
plate which is hooked onto the pin c, when it is desired to close the fastening, as
shown in Figs. 1 & 2.
In order to prevent the plate 6 becoming unhooked from the plate a, a tongue d
is pivoted to the plate b the inner end of which is adapted to enter the open
side of its eye b¹ and bear against the pin c of the other plate a thus locking
the two plates securely together.
To facilitate the moving and setting of the tongue d its outer end is bent and
may project through a segmental slot e formed in the plate b.
The plates a & 6 are secured to the tune sheet or the like by means of rivets f
or the like, sinal distance collars g, see Figs. 2 & 4, being interposed to form a
space between the tune sheet and plates for the tongue d to move in.
The invention described is also applicable to doors in place of the ordinary
-hinges and permits of removing the door readily from the door post when required
without the necessity of removing the hinges.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim, is :—
1st. In a hinge fastening for tune sheets, jacquard cards, belting, writing cases,
doors and the like, the combination of two plates a & b, a of which is formed with
two eyes a¹, a¹ carrying a pin c, and b with a hooked shaped eye b¹ adapted to
engage the pin c, all substantially as sef forth.
2nd. In a hinge fastening for tune sheets, jacquard cards, belting, writing cases,
doors and the like, in combination with the hinge plate b, b¹ a tongue d adapted to
enter the hooked eye b¹ when placed upon the pin c of the plate a and thus lock
the two plates a & b together, all substantially as set forth.
