Improved Means of Attachment for Glass Plates suitable for
Construction of Show Cases and the like.
I, REGINALD HADDAN, of the Firm of Herbert Haddan and Co., of 18, Bucking-
ham Street, Strand, W.C., London, Patent Agent, do hereby declare the nature
of this invention a communication to me from abroad by James Leo Crane, of
the City of Cleveland, County of Cuyahoga, and State of Ohio, in the United
States of America, Manufacturer, 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 store-fronts or show-windows and
show-cases.
The object of this invention is to provide an improved construction, and
arrangement of parts, in fastening two glass-plates, that are arranged at an
angle to each other, at the corner formed between the said plates, without
weakening the said plates at their meeting or adjacent edges, and without inter-
fering with a tight fit between the plates, and without concealing the finely
finished edges of the plates.
Another object of the invention is to provide a top corner-clamp for use in
the construction of show-cases, and not only instrumental in holding together
and preventing end-wise displacement of the connected upright plates, but instru-
mental, also in holding the top plate downwardly upon the said upright plates.
With these objects in view, the invention consists in certain features of con-
struction and combinations of parts, hereinafter described and pointed out in
the claims.
In the accompanying drawings, Fig. I is an exterior view of a show-front
embodying the invention.
Fig. II is a horizontal section on either one of lines II-II, Fig. I, and
shows the parts full-size.
Fig. III corresponds with Fig. II, except that in Fig. III the corner-clamp
is removed.

Fig. V is a vertical section on line V-V, Fig. III, looking in the direction
of the arrow.

Fig. VII is a top plan in horizontal section, corresponding in the main with
Fig. II, but showing a slight modification.
Fig. VIII is a top plan of a corner of the show-case or show-window embodying
the invention.
Fig. IX is a vertical section on line IX-IX, Fig. VIII.
Referring to the drawings, A and B designate two upright glass-plates of a
show-window, that are arranged at an angle to each other and are tightly fitted
together. The meeting or adjacent edges of the said plates are ground and
polished. In the case illustrated, A represents the front plate of a show-window,
and B one of the side plates of the window. In any case however, the invention,

page_text: essentially, involves two glass plates arranged at an angle to each other and
tightly fitted together. In the case illustrated, the front plate A overlaps the
edge of the side plate B.
To prevent the glass plates from being broken by lateral pressure, occasioned
by heavy winds, or by the tools or instruments employed in cleaning the plates,
or accidentally by persons or objects participating in the display of goods within
the show-window, the invention comprises corner-clamps, or fasteners, 1), at
two or more points between the upper and lower ends of the plates. Each of
the said corner-fasteners involves, essentially an outer angle-plate or jaw, D',
an inner jaw or plate 12 and means instrumental in connecting the two plates Di
and De together. Registering recesses F in the meeting or adjacent edges of the
glass plates accommodate the location and operation of the connection between
the parts D and D2. The outer jaw or angle-plate D¹ has two arms or wings d
and arranged to engage the outer side of the different glass plates, A and B,
respectively, at the external corner formed between the two glass plates. The
inner jaw or plate D has two arms or wings d² and arranged to engage the
inner side of the different glass plates, respectively, at the internal corner formed
between the glass plates. In the case illustrated, the connection between the
two jaws or plates 101 102 is a stud or screw that is rigid with the outer jaw
or plate D at the latter's angle, and projects inwardly, in a horizontal plane,
and diagonally, and extends through the registering recesses F F formed in the
meeting edges or ends of the glass plates, and loosely through a hole formed in
the inner jaw or plate D2, and a nut mounted upon the stud or screw, is
arranged to secure the two jaws or plates D1 D2 in their operative position wherein
they clamp the two glass plates between them.
As already indicated, the two glass plates A and B are ground and polished
at their meeting or adjacent edges, and are tightly fitted together. The sectional
views, Figs. II, III and IV show the fit described between the two glass plates.
There is no drilling of holes in the glass plates near the latter's edges but the
plates are recessed horizontally, as at F, in their meeting edges or ende, and the
recesses are open, therefore, at the edges of the plates and do not weaken the
latter in any respect. Each recess F, in plate B, is formed at the junction of
the inner side and edge of the plate and registers with a recess F formed in
plate A, as shown more clearly in Figs. III and IV. The sectional view, Fig. VII,
shows a slight modification in that the front plate A projects edgewise a short
distance beyond the outer side of the side plate B, so as to form an angular
recess G between the outer side of the side plate and the rear side of the front
plate, and, in this case, the arm d¹, of the outer angle-piece or jaw D¹ is enlarged
inwardly, as at 1³, into the said recess, to form an adequate bearing for the outer
side of the side plate B, and to form a shoulder or bearing 1 for the rear or
inner side of the projecting portion of the front plate A.
One of the jaws or angle-plates of the corner clamp and preferably the external
jaw, is provided with two lugs do and that engage recesses a and b, respectively,
formed in the plates A and B respectively, and the said engaging lugs and
recesses prevent endwise displacement of the said plates A and B. The lugs do
and are formed upon the different arms or wings d and d¹ respectively of
the external jaw, and are formed upon the inner side of the said jaw, and the
engaging recesses a and b are formed in the external sides of the plates A and B
in the same horizontal plane with the recesses F that are formed in the adjacent
ends of the said plates A and B for the accommodation, as already indicated,
of the location of the operative connection between the two jaws. The location
of the lugs and and the said operative connection in the same horizontal
plane facilitates the formation of the recesses formed in the glass plates and
saves labour and expense in the assemblage of the parts.
One of the jaws of the corner-clamp located adjacent the top plate G, and
the outer jaw in the case illustrated (see Figs. VIII and IX) is provided with
means that is instrumental in holding the said top plate G downwardly upon

page_text: the upright plates A and B, and the said means, in the case illustrated, comprises
a vertically arranged screw that extends through the top plate, has a head ¹
bearing downwardly upon the upper side of the top plate and has its shank
engaging a correspondingly threaded vertical hole formed in one of the jaws
of the clamp. In Figs. VIII and IX of the drawings, do designates the vertical
hole formed in the clamp's outer jaw, at the jaw's central portion, which hole
is engaged by the screw that is introduced through the hole g extending through
the top plate G. It is obvious that, upon turning the screw in the one direction,
the top plate G will be caused to bear downwardly upon the upright plates A
and B, and the top plate will be loosened relative to the said upright plates,
upon turning the screw in the opposite direction.
The aforesaid improved manner of securing together adjacent or meeting
upright plates, and ine contiguous top plate, at the corner formed between the
said plates, is important, because it does not require recessing or cutting away
of the upright plates, and because it is not only inexpensive but possesses great
efficiency and durability. It may sometimes be desirable to fasten the top plate
to the inner jaw of the corner-clamp instead of to the outer jaw, or to both
of the said jaws, and the inner jaw, to accommodate the fastening of the top plate
thereto, is provided, at its upper portion, with a web that has a vertical screw
threaded hole 10 for accommodating the reception of a screw that would then
be employed in attaching the top plate to the internal jaw.
It is obvious, also, that the construction shown in Figs. VIII and IX might be
used at the bottom of a show case having a glass bottom connected with the
upright glass plates by the clamp or fastener shown in the said figs.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
