Patent, Trade Marks, & Designs Agent, for the Invention of "AN IMPROVED
SHANK FOR BUTTONS." A communication from abroad by Férréol Perrin, of
Grenoble, France. .

PROVISIONAL SPECIFICATION left by the said Frederic Des Voeux at the
Office of the Commissioners of Patents on the 12th March 1879.
FREDERIC DES VEUX, of 32, Southampton Buildings, London, Patent, Trade
Marks, and Designs Agent. "AN IMPROVED SHANK FOR BUTTONS.". [A com-
munication from abroad by Férréol Perrin, of Grenoble, France.]
My Invention relates to certain improvements in the shanks or stems of buttons
for the more easily and securely attaching them to gloves and clothing generally.
I drill a hole through the button through which from the under to the upper
side passes the shank, which is securely fixed therein. The shank is manufactured
of brass or other suitable material, and passes through and is securely attached to
a thin plate of the same material of suitable shape and dimensions, but advantage-
ously round and slightly smaller than the button. To the end of the shank is
attached a plate similar to the first, which is cut from the edge to near the centre
and the cut part bent downwards.
The shauk is thus in a "corkscrew" shape, and may be easily screwed into the
material for which it is required. The material fits in between the two plates,
and is rendered secure by the shank being lightly struck by a hammer, or clenched.

FREDERIC DES VŒUX, of 32, Southampton Buildings, London, Patent, Trade
Marks, and Designs Agent. "AN IMPROVED SHANK FOR BUTTONS." (A com-
munication from abroad by Ferréol Perrin, of Grenoble, France.)
This Invention relates to certain improvements in the shanks or stems of buttons
for the more easily and securely attaching them to gloves and to clothing generally.
A hole is formed through the centre of the button in which the shank is securely
fixed. The shank is manufactured of brass or other suitable material in the form
of a pin, and on the lower side of the button passes through and is securely attached
to a thin plate or disc of the same material and slightly smaller than the button.
To the end of the shank is attached a plate or disc similar to the first, which is cut
from the edge to near the centre and the cut part bent downwards.
The shank with the lower plate so cut may be readily screwed into the material
for which it is required, a small hole having previously been pierced therein to
adinit the point.
The material fits in between the two plates or discs, and is rendered secure by
the lower plate or disc being slightly struck by a hammer or clenched in a machine
for the purpose.

In the accompanying Drawings serving to illustrate the nature of the Invention,
and the manner of performing the same,-
Fig. 1 is a side view; Fig. 2, a section through the line 1, 1, of Fig. 1; and
Fig. 3, a perspective view; the same letters indicating corresponding parts in the
different Figures.
a is the button, through which passes the shank b; c, c¹, the upper and lower
plates or discs fixed to the shank b; d (Fig. 2), a piece of leather or other material
secured between the plates or discs c, c¹. Fig. 3 shews the cut e in the lower plate
or disc c¹.
Having thus described the nature of the Invention communicated to me from
abroad, and the manner in which the same is performed, I would have it under-
stood that I do not claim any of the above mentioned parts separately, which are
old and well known, but what I claim on behalf of the said Ferréol Perrin is, the
improved arrangement and construction of the shanks of buttons having plates or
discs c, c¹, between which the leather or other material is secured, substantially as
above described, and shown in the Drawings hereto annexed.
In witness whereof, I, the said Frederic Des Voeux, have hereunto set my hand
and seal, this Tenth day of September, in the year of our Lord One thousand
eight hundred-and seventy nine.
