I, LAWRENCE READ, Chairman of the Dental Manufacturing Company, Limited,
of 6, Lexington Street, Golden Square, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
In preparing mineral teeth for insertion in vulcanite or other material it is
customary to bend the pins to a hook or right angle. When the ordinary pliers are
used there is always a liability to strain or crack the tooth substance. My inven-
tion is designed to bend the pins at any required angle without causing any strain
whatever upon the tooth substance, the pins being firmly held by the pliers while
the pins are bent over by the pivotted lever as follows:-
One of the jaws of the pliers is slotted and a lever is pivotted in this slot its nose
entering a slot or recess in the other jaw. In using the instrument the pin or pins
of the tooth are placed between the jaws and are held by them. The lever is then
turned about its pivot and its nose sweeping past the wires or pin or pins so held
bends them into hooks or angles, as desired.
Although these improved pliers are specially designed for the use of the dentist,
they are capable of universal application in other classes of mechanical work where
such a need is felt.

Improvements in Pliers especially Suitable for Dentists.
1. LAWRENCE READ, Chairman of the Dental Manufacturing Company, Limited,
of 6, Lexington Street, Golden Square, in the County of Middlesex, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
In preparing mineral teeth for insertion in vulcanite or other material it is
customary to bend the pins to a hook or right angle. When the ordinary pliers are
used there is always a liability to strain or crack the tooth substance. My inven-
tion is designed to bend the pins at any required angle without causing any strain
whatever upon the teeth substance, the pins being firmly held by the pliers while
the pins are bent over by a pivotted lever.

page_text: Figure 1 is a central longitudinal section of a pair of pliers made according to
this invention and Figure 2 is a perspective view of the same.
The jaw a of the pliers is slotted and a lever b is pivotted in this slot its nose
entering a slot or recess in the other jaw c. In using the instrument the pin d
(or pins) of the tooth e is placed between the jaws when they are in the position
shown in Figure 2 and is held by them. The lever b is then turned about its pivot
into the position shown in Figure 1 and its nose sweeping past the pin so held bends
it into a hook or angle as desired.
Although these improved pliers are specially designed for the use of the dentist,
they are capable of universal application in other classes of mechanical work where
such a need is felt.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination with a pair of pliers of a lever pivotted to one of its jaws
substantially as described.
2. Pliers substantially as described and illustrated in the drawings
