COMPLETE SPECIFICATION.
Improvements in Buckles or Fasteners for Driving Belts, Bands,
Articles of Clothing, and other Analogous Purposes.
We ANTON TEHNIK Postmaster of Kronow in the Kingdom of Bohemia and
FRANZ VAVRA Engineer of Prague in the Kingdom of Bohemia do hereby
declare the nature of our said invention, and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in that class of buckles described in the
specification of Letters Patent No. 17572 dated the 5th November 1889. By means
of the improvements hereinafter described our improved buckle can be used for
connecting together the ends of belts, bands and for similar fastenings such as are
used for military for clothing and for driving purposes.
Figs. 1. to 3. shew a modified arrangement of the buckle such as may be advan-
tageously used for waist-bands and light transmission belts, Fig. 1. being a plan,
Fig. 2. a side view and Fig. 3. a longitudinal section thereof. Figs. 4. to 7. shew
another arrangement of the buckle used as a means of fastening articles of clothing,
Fig. 4. being a side view, Fig. 5. a longitudinal section, Fig. 6. a plan and Fig. 7. a
rear view of this contrivance.
In the arrangement shewn in Figs. 1. to 3. one of the ends of the belt is firmly
connected to the sheath a. The latter is bent over as illustrated at a¹ so as to form a
guide for the other end of the belt still remaining to be fastened. The fastening
device d which presses with its upper roughened or serrated surface d' against the
under rough side of the end of the belt, is guided beneath the sheath by a peculiarly
bent-over pieced and rests with the roughened wedge shaped surface against the
In order to be able to conveniently clean the parts of this fastening or device
and to guide the end of the belt, the fastening device is provided at its front
extremity with a shackle d³. This device d is secured from dropping out by a slot a
formed in the sheath a to receive the projection of the fastening device d.
belt.
In the buckle used for fixing articles of clothing and shewn in Figs. 4. to 7. the
fastening device d is roughened on its inner surface and has a tapering or wedge
shape corresponding to the sheath part a of the buckle being further guided in the
space formed between the two surfaces a a¹ of the sheath.
Owing to the sliding motion of the locking device d upon the wedge shaped
surface a caused by pulling one of the extremities of the band the appliance d
becomes forced between the surfaces and will be firmly and safely secured.
A link
or shackles permits of a connection being effected between the buckle and the
corresponding article of clothing such connection being capable of turning and easy
to form. The fastening device d surrounds the sheath a a' and is guided by slots.
parallel to each other and to the edge a'. This wedge like buckle constituting a
fastening which is nearly automatic in action.
Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
wo claim is:-
In an improved buckle suitable for the automatic connection of belts, bands or
similar articles also applicable to articles of clothing to harnessing or yoking to

page_text: vehicles and for other analogous purposes the combination of the wedge shaped
sheath a with the corresponding locking device d the one capable of sliding within or
upon the other substantially as hereinbefore described.
