COMPLETE SPECIFICATION.
Improvements in Securing Covers or Lids to Boxes and
Similar Receptacles.
I, OSKAR WITTWER, of Kunzendorf, near Steinau on the Oder, in the Kingdom of
Prussia, German Empire, 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 object of this invention is to secure covers to boxes, cases, and such-like
articles, without employing nails or screws, thereby allowing of the cases being used
over and over again.
In carrying out this invention, the cover is made to slide on and off, and the
invention consists in the means provided for locking the cover to the box or case, in
such a manner that the locking device will not impede the opening of the box, when
desired.
In the accompanying drawings
:-
Figs. 1, 2 show in front view and longitudinal section, one mode of securing the
cover to the box without nails or screws; and
Figs. 3 and 4 represent, also in front view and longitudinal section, the case as
half opened.
Figs. 1 and 2 show a modified arrangement of box or case.
Referring now to Figs. 1, 2, 3 and 4, D is the cover, which is fitted to slide in the
grooves N formed in the sides and one end of the box, and it is intended to overlie,
when closed, the fourth (or front) side W of the box. That portion of the groove
which is nearest the front of the box is widened out, as shown at N¹, for a purpose
to be presently explained. To the underside of the cover D is secured, in any
convenient manner, the slat A, the inner edge of which is bevelled, so that it may
ride over the edge of the side W, when the cover is pushed in. The spring of the
wood will permit the cover to rise in the wide part N¹ of the groove N, to allow the
slat A to pass over the front W of the box. To prevent the raising of the cover D,
when the box is closed, the cross bar R is adapted to the upper surface thereof, such
bar turning on the pivot Z, so that its ends may enter and fill up so much of the
widened part N¹ of the groove N, as is necessary to effect the result desired. In
order to secure the bar against undue opening, a band of paper or woven fabric is
gummed or otherwise fastened over the bar R, and on to the cover D. When it is
desired to open the case, the bar R, after the said band has been removed, is turned
from its position in the groove N¹, that is to say, transversely of the cover, to
the position shewn in Figs. 3 and 4, that is to say, longitudinally of the cover, and
the cover, which is now free to rise, is raised until the slat A can pass over the front
wall W of the case.
If grooves in the sides of the case are objected to, the cover may be arranged to
overlap the sides and the front, and to abut against the fourth side or back. In this
case, the front and back are provided with a framework, the top bars H, H¹, of which
are so arranged that the cover D shall pass under them, as shown at Figs. 1 and 2^.
The cover will, as before, be provided with the slat A, fastened to the underside

thereof, and the lifting of the cover will be prevented by the bar R, which will be
inserted between the cover D and the bar H, a space being left between the bar H
and the top of the cover D, to allow the cover to rise, to pass the slat over the edge of the
front wall W. The bar H¹ may serve to hold down the rear end of the cover, or it
may be raised, like the bar H, so that I may insert, under the bar H¹, another bar R¹,
which is rigidly connected therewith. To make a secure fastening, leaden cords or
wire may be passed around the bar H and around the bar R, through the notches
or grooves K K. In order to open the box or case, the bar R, after the leaden wire or
cord has been cut or otherwise unfastened, pushed outward, and the front end of
the cover D can then be raised, so that the slat A may pass over the front wall or
side W.
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 :-
1. A fastening for the covers of boxes or cases, in which the cover D is protected.
(10) against a sliding movement by means of a slat A fastened to its under surface,
and tapering grooves N, N1, in the sides of the case (Figs. 1 to 4) or by means of a slat A
fastened to its under surface and frames H H¹ (Figs. 14 and 24) surrounding the front
and back walls or sides W W₁; and (2°) against a lifting movement by means of a
bar R taking into the grooves NN¹, or inserted between the upper portion H of the
frame and the cover D, as set forth.
2. Securing the bar R in the desired position by means of a paper or similar band
gummed or otherwise fastened over the bar R onto the cover of the case, or by means
of a leaden wire or cord laid around the bar R and the upper cross bar H, as set
forth.
