A Device for Fastening or Securing the Carrying Straps of
Knapsacks and like Receptacles.
We, RUDOLPH DUNKELBERG, of 58, Ulinenstrasse, Dusseldorf, in the Empire of
Germany, Army Contractor, and GUSTAV GOCKEL, of 20, Adersstrasse, Dusseldorf,
aforesaid, Manufacturer, 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:--
The invention forming the subject matter of this application for patent has
for its object to remedy the defects which are inherent to the mode of fastening
knapsack straps to knapsacks as now in use.. Both in military; knapsacks and
in those intended for other purposes, the straps are fastened with screws.
screws, which project beyond the strap, exert a pressure, incommoding the person
carrying the knapsack.
These
This mode of fastening, moreover, is subject to the evil that it is very difficult
to lengthen, or shorten the strap and that the strap is very likely to break at
the place in which it is fastened by the screws. These objections are overcome
by the present invention.
The invention is illustrated in the annexed drawing in which;-
Figure 1 is a general view shown in perspective of the device according to
this invention showing the mode of fastening.
Figure 2 is a section through the fastening device.
Under this invention the wooden frame of the knapsack, which is covered
with strips of leather a has fastened to it, by rivets c, a metal plate which at
the end situated towards the knapsack hook has attached to it, by hinges dd',
a triangular metal flap e which at its lower end is provided with a strong pin f,
likewise made of metal. This flap is arranged so that when it turned
upwards a slot g is formed between the two hinges dd through which the
strap for carrying the knapsack is passed. In the leather covering of the
knapsack, a hole is provided, which is extended downward, corresponding
to the position of the pin f, and which serves to receive the pin f when the flap
is turned down.
One end of the knapsack strap is fitted in the known manner with an eye or
other suitable arrangement for attaching it to the knapsack hook while the other
end is provided with holes k, of dimensions to correspond with those of the
pin f.
The device is used as follows:-
The flap is turned upwards and the knapsack strap is passed, with the
perforated end, through the slot y, as far as is requisite. In doing so care should
be taken to see that one of the holes in the strap is placed over the hole i. If,
now, the flap e is depressed the pin f will pass through the hole k in the strap,
into the hole in the knapsack, and the strap will thus be fastened quite safely.
This fastening arrangement presents no projecting points, but lies smoothly on
the back of the bearer of the knapsack.

page_text: In order to alter the length of the strap all that is required is to raise the flap
and pull the strap out or push it through further, as required.
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 ;-
A device constructed substantially as herein described for fastening the carry-
ing straps to knapsacks and like receptacles, characterised by a flap e hinged
to the frame of the knapsack, or to a special plate, and which, if raised, will
permit the perforated end of the carrying strap to be passed through a slot formed
between the hinge, and on being depressed will firmly attach the strap to the
knapsack by means of a pin f which passes through one of the holes in the
strap into a hole i in the knapsack frame, as set forth.
Dated this 15th day of May 1899.
