PROVISIONAL SPECIFICATION.
Improved Device for Protecting Articles from Damage when
being Nailed.
I, CARL FRIEDRICH BELLINO, of Goppingen, in the Kingdom of Württemberg
Manufacturer, do hereby declare the nature of this invention to be as follows:-
It is well known that the liability of covers of packing cases, casks etc. to be
broken up and damaged in being nailed in their place has hitherto constituted a
very serious inconvenience.
The object of this invention is to protect the surfaces of boxes, casks and other
receptacles when nails are driven into the same and to facilitate the removal of the
nails without the use of hammers chisels or other auxiliary tools.
By means of this invention a great saving of time and labor is effected and the
pieces of wood or the like to be fixed by nails or tacks are prevented from being
split, cracked or otherwise damaged in the process.
In the accompanying drawings the improved device is illustrated.
A plate or washer of hemispherical pyramidal or other suitable shape is provided
at its upper part with an opening a the edges of which are somewhat depressed.
Instead of this opening however, a mere recess may be sufficient. The lower part
of the opening or recess may be somewhat tapered.
The nail is inserted through the opening a and then driven in by means of the
hammer until the head of the nail is embedded in the upper portion 6 of the washer.
If the protective washer has only a recess instead of an opening at a, the nail has,
of course, to be driven through the bottom of the recess.
The lower edge d of the washer is in the process of driving in the nail forced
somewhat into the wood or other material and thereby more securely maintains
the nail or the like in its place, and also prevents the wood from cracking
Moreover should the wood crack, the split portions thereof are held together by
the washer.
When the fastening is to be undone, pinchers (see dotted lines Fig. 3) are used to
compress laterally the protective washer to a certain extent whereupon the nail
may be drawn up which is facilitated by the strain to which both the wood and the
nail itself are subjected.
The washers may be employed over and over again any number of times.

Improved Device for Protecting Articles from Damage when
being Nailed.
I, CARL FRIEDRICH BELLINO, of Goppingen in the Kingdom of Württemberg,
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 liability of the covers or lids of packing cases, casks etc., to be split and
damaged when being nailed in place has hitherto constituted a very serious
inconvenience, and the object of this invention is to protect the surfaces of such
boxes, casks and other receptacles, when nails or the like are driven into the same

page_text: and to facilitate the removal of the nails or the like without the use of hammers
chisels or other auxiliary tools.
By means of this invention, a great saving of time and labour is effected and the
pieces of wood to be fixed by the nails or the like are prevented from being split,
cracked or otherwise damaged in the process.
In the drawings filed with my Provisional Specification.
Fig. 1 shows one form of my protecting device in plan and vertical section.
Fig. 2 shows in plan and cross section the mode of applying such device.
Fig. 3 is a similar view to Fig. 2 shewing the manner in which the device and
the nail passing therethrough can be withdrawn from a piece of wood to which
they have been applied.
The said device according to my invention, consists of a plate or washer of
suitable metal or material such as iron, steel or brass, hemispherical, pyramidal or
other suitable cup shape. At its upper part it may be formed with an opening a
the edge or edges of which is or are slightly depressed and may be tapered or
.bevelled inward as shewn.
The nail to be used with such a device is inserted through the opening a and
then driven in by means of a hammer until the head is embedded in the upper
portion b of the washer. In some cases there may be only a recess at a instead of
an opening in which case the nail must of course be driven through the material at
the bottom of the recess.
The lower edge d of the protective device is slightly sharpened so that in the
process of driving in the nail such edge will be forced to some extent into the
wood, thus assisting to maintain the nail or the like in place, and at the same time
also preventing the wood from readily splitting, or if splitting should take place,
the split portions of the wood will be held together by the said device.
When a nail used with such a device is to be withdrawn, pincers are used to
compress the device laterally to a certain extent as shewn in Fig. 3, whereupon the
nail can be easily drawn out, this being facilitated by the strain to which both the
wood and the nail itself are subjected by the compression of the device, so that
the withdrawing operation can be effected without loss of time and without the
assistance of any other tools.
A device according to my invention can be used over and over again a great
number of times.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that
what I claim is :-
For protecting articles from damage when being nailed a device constructed
substantially as shewn in and described with reference to the drawings.
Dated this 18th day of August 1893.
