COMPLETE SPECIFICATION.
Improvements in Clamps or Clasps for Broken Glass.
1, FREDERICK EVERITT DUNHAM, of 73 Jane Street, of New York, in the
County and State of New York, United States of America, Merchant, 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 clasps or clamps for broken glass, and the object
thereof, is to provide a simple and effective device for clamping together the
sections of a broken glass, and the invention is particularly adapted for use in
connection with large washer glass which have been pierced or broken and have
a small hole or holes formed therein, from which cracks radiate and which are in
danger of falling out of the frame.
The invention is fully disclosed in the following Specification of which the
accompanying drawing forms a part, and in which ;-
Fig. 1, represents the method of applying my improved clasp or clamp to a
broken glass; and,
Fig. 2, a section on the line 2, 2, of Fig. 1.
In the accompanying drawing, A, represents an ordinary window, or other glass
mounted in a frame B, and my improved clasp applied thereto, is constructed as
follows.
of
Supposing that the glass has been broken, and punctured, I employ a plate C,
any desired form, preferably circular, and also preferably formed of metal, and
centrally of the plate C, is secured a screw threaded bolt, or pin D, which is
passed through the puncture or hole in the glass, and on which opposite the plate C, is
placed a washer E, of cork, or similar material, and similar in form to the plate C,
and over the washer E, is placed a plate F, preferably of metal and similar in form
to the washer E, and plate C.
I then place upon the screw threaded bolt or pin D, a screw threaded thumb
nut G, which is firmly screwed down upon the plate F, and by means of which the
separate plates of the clamp and the washer E, are firmly connected with the glass,
on each side thereof, and the latter is securely held thereby, and the broken
portions are retained in place, as will be readily understood.
I may also employ a cork or other washer between the plate C, and the glass if
desired, and it is evident that changes in the form, construction and combination
of the various parts may be made without departing from the spirit of my
invention, and I therefore reserve the right to make such alterations therein, as
fairly come within the scope thereof.
Having fully described my invention; I claim and desire to secure by Letters
Patent :-
1. A glass clamp or clasp, consisting of a plate, provided with a screw threaded
bolt or pin adapted to be passed through a puncture or hole in the glass, a plate
mounted on said pin or bolt, and a screw threaded thumb nut, by which said
plates are caused to clamp and hold the glass, substantially as shown and
described.
2. A glass clamp or clasp, consisting of a plate or head, provided with a screw
threaded bolt or pin, adapted to be passed through a punctured hole in a glass, a
washer mounted on said pin or bolt and means for clamping said washer, and said

page_text: plate or head to the glass, on opposite sides thereof, substantially as shown and
described.
3. A glass clamp or clasp, consisting of a head or plate, provided with a screw
threaded bolt or pin, adapted to be passed through a puncture or hole in a glass, a
washer of cork or other material mounted on said bolt or pin a plate also mounted
thereon, and a screw threaded thumb nut, by means of which the parts may be
securely clamped to the glass, substantially as shown and described.
Dated this 16th day of August 1895.
