PROVISIONAL SPECIFICATION.
Improved Case for Spectacles and other Articles, and Method of
Making same.
I, ELIJAH ASA DARLING, of Willis, Michigan, U.S.A. Dealer in Agricultural
Implements, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a simple and cheap case for spectacles
made in one piece and therefore stronger and cheaper to produce than those made
of more parts, and further my invention relates to the method of making said
cases.
In carrying out my invention I provide a piece of wood or other suitable
substance and shape it on the outside to the desired pattern. Then by means
of a rotary saw or cutter, I make a groove along one side of the blank extending
in depth nearly to the other side. The blank is then held vertically and a similar.
cutter of the required width and diameter to form the interior of the case is then
used to cut out the interior, the shaft of the cutter passing through the slot
aforementioned. When the blank has been thus hollowed, the slot in one side
thereof is filled by glueing or otherwise securing a strip of material therein. The
case is then fitted with a suitable lid which is made in a similar manner. "
If desired the preliminary operation of slotting the blank may be dispensed
with by forming the shaft of the cutter with cutting edges as will be readily
understood.

Improved Case for Spectacies and other Articles, and метлой от
Making same.
I, ELIJAH ASA DARLING, of Willis, Mich., U.S.A. Dealer in Agricultural
Implements, 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 --
This invention relates to an improvement in cases for spectacles, pencils, pens,
etc., and it consists in the construction and arrangement of parts as hereinafter
described and definitely pointed out in the claim.
In the drawings,
Figures 1 and 2 show the blank in different stages of formation.
Fig. 3 shows the saw cutting the longitudinal kerf or slot in the blank.
Fig. 4 shows the shaping saw for shaping the interior of the case.
Figs. 5 and 6 are cross sections through the blank after the operations by the
machines shown in Figs. 3 and 4 respectively.
Fig. 7 is a perspective of the case ready for finishing.
Figs. 8 and 9 are cross sections through the finished case:
Fig. 10 is a perspective of a finished case.
Fig. 11 is an elevation showing a modified form.

page_text: Fig. 12 is a cross section similar to Figs. 8 and 9 showing a slight modification
in interior finish.
Fig. 13 is a view of a blank showing a slightly modified form of cutter for
shaping the blank.
In the manufacture of the case I preferably start the blank, substantially as
shown in Figs. 1 or 2, the blank A shown in Fig. 1 simply having rounded edges,
while the blank B shown in Fig. 2 is shaped to the shape of the desired finished
article. The shaping of the blank or case may be done before the interior of the
case is cut out or after. I prefer to do it before cutting out the interior as there is
Jess danger of breaking, than if it is done after. Taking the blank thus described,
I first cut in it a longitudinal groove C which extends from one end to near the
other end of the blank. This may be done by means of a circular saw D as shown
in Fig. 3; E being the guide block beside which the work is moved. This groove
is of such a depth as to leave at the bottom thereof a thickness of material, as
shown at F, substantially the thickness that I desire to form the case, and is of a
width as great or greater than the mandrel of the saw which I use in cutting out
the interior.
The blank, thus formed, shown in Fig. 5, is next brought to the saw, as shown in
Fig. 4, being guided by the guide bar G, the mandrel of the saw passing through
the slot or groove C on the blank and the saw cutting the material on both sides of
such groove, leaves the casing entirely round it and forms the blanks shown in
Fig. 6. The use of a saw with a rounded edge leaves a blank substantially as
shown in Fig. 7 with the longitudinal kerf or slot extending from one end to near
the other. I bevel the edges of this kerf and fill it up, either by means of a
bevelled strip H as shown in Figs. 9 and 10, glueing the same in, or by means
of a bridge strip I as shown in Figs. 8 and 11 leaving a recess J for the bows of
the spectacles.
This bridge strip I preferably make with a reinforcing rib K to strengthen the
case.
Instead of making two steps of cutting the kerf and sawing out the interior,
I may do this in one operation, as shown in Fig. 13, by arranging cutters L on the
mandrel of the saw, so that a path or groove will be cut in addition to that made
by said saw.
The outer edges may be round, square, (Fig. 10) or slightly rounded as shewn
in Fig. 11. The mouth of the finished article is preferably bevelled towards the
front as shewn in Figs. 10 and 11.
A lid made in the same manner as the case may be hinged or otherwise fitted
thereto if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) A case for spectacles and other articles consisting of a flat non-yielding
integral block, having a cut out flat chamber in its centre, open at one end and
closed at the other end, a relatively uarrow groove, in one of its sides of a length
less than the length of the chamber, and a narrow closing strip for the groove
formed separate from the block, secured to the case, substantially as described.
(2.) As a new article of manufacture, a spectacle case formed of a single piece
of wood having a chamber and a longitudinal groove therein, and a closing strip
for the groove secured to the case and formed with a flat under, and arched
upper face, substantially as described.
