COMPLETE SPECIFICATION.
A New or Improved Device or Means for Use in Transporting,
Mounting, or Dismounting Plate Glass or the like.
We, CARL VORPAHL, Merchant, and FRIEDRICH NEUHAUSEN, Joiner, both
of 54, Webergasse, Wiesbaden, in the Empire of Germany, 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 a device by means of which large sheets of plate glass:
or the like may be readily and conveniently carried from place to place and also
held while being fixed in place in the window frame or elsewhere or taken out of
the same or dismounted.
The device is illustrated in the accompanying drawings, referring to which :-
Fig. 1 is a sectional view of the device.
Fig. 2 is a perspective view of the same, and
Figs. 3 and 4 show the method of using the device and the necessary
accessories.
The device comprises a metal shell or box a provided with a stirrup or curved
portion b which carries the handle c. This shell a is filled with a substance d
which will be hereinafter described.
Two hooks e el are also provided of which the larger e serves for the attachment
of the device to a pulley or the like whilst the smaller e' serves to prevent the
larger hook from slipping or being pulled out.
The substance with which the metal shell or box a is filled may be prepared in
the following manner :-
About kilogramme or wax is melted over a fire and to this is then added about.
kilogramme of colophony and when this mixture is dissolved kilogramme of
linseed oil is mixed therewith the whole mass being thoroughly stirred; after this
about kilogramme of Cassel earth is mixed with this mass which is exposed to
the heat of the fire until it becomes completely liquefied. Care must however be
taken on no account to allow the mass to reach a state of ebullition.
The apparatus is filled with the substance prepared in this manuer by first
placing it upon a plate covered with wet paper and then pouring the substance
through the openings 9 provided in the upper portion of the shell a.
When it is desired to make use of the apparatus the under plate is heated for
some minutes in the flame of a spirit lamp and the apparatus is then firmly pressed
upon the sheet of glass which it is desired to move when it will strongly adhere to
the same.
a indicates the receptacle or shell, c the handle, e the pulley hook, e¹ the
counter hook, h the connecting hook and i the mutually opposed supporting
rods.
The receptacles or shells a are arranged upon both sides of the sheet of glass A
which is to be moved (Fig. 3) in such a manner as to be exactly opposite one
another or as nearly so as possible. If the sheet of glass is very large a series of
these receptacles is used and the supports i are attached to the upper device on
each side by engagement with the hooks e'.
The device is separated from the glass by means of a tool such as k the blade of
which is inserted between the apparatus and the sheet of glass.

page_text: In order to fix the apparatus the mass contained in the receptacle a is heated
over a spirit lamp until it becomes soft. It is then pressed against the sheet of
glass when it immediately hardens and adheres firmly to the glass.
When desired the substance can of course be renewed.
With the apparatus above described it is possible to transport large plates of
glass (up to about a ton or more in weight) without any danger of the apparatus
becoming detached from the sheet of glass.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A device for use in the transportation fixing in place and dismounting of sheets
of glass consisting of a receptacle or shell such as a open at the bottom and
provided with a handle such as c said receptacle filled with an adhesive substance
or composition (such as a mixture of wax, colophony, linseed oil and Cassel earth
for example) which substance is adapted after being exposed to a certain heat to
firmly adhere to the sheet of glass all substantially as and for the purposes
hereinbefore set forth.
