Improvements in and relating to Dentu
or Securing Artificial Teeth by Atmospheric Suction.
I, ALEXANDER PEEL PATTERSON of 197 Bridgman Street, Bolton in the County of
Lancaster, Dentist, do hereby declare the nature of my said invention to be as
follows:-
The object of this invention is to improve the construction of such artificial palates
as are retained in their places by suction by providing means for more effectually
securing and retaining the vulcanised india-rubber or pneumatic washer or valve
employed for the purpose. The said vulcanised india-rubber or pneumatic washer or
valve is secured to the top side of the palate by a hollow tube provide with a closed
end or solid head.
In carrying out my invention I form a hole in the denture or palate in which is
fixed an annular metal tube which allows of the open end being closed in an efficient
manner by a punch or a pair of grips; the pneumatic washer or valve being secured in
position by the solid head of the said tube.
My invention may be adapted to dentures or palates of vulcanite, platinum, or any
of the materials used for the purpose in dentistry.
The advantages accruing from this invention are that the pneumatic washer or
valve is more firmly secured than hitherto owing to the easy method it allows for
punching or gripping; also that it minimises the risk of cracking or damaging the
denture or plate when fixing.
Dated the 29th June 1886.

I, ALEXANDER PEEL PATTERSON of 197 Bridgman Street, Bolton in the County of
Lancaster, Dentist, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by. the following statement:
The object of this invention is to improve the construction of such artificial palates 5
as are retained in their places by suction by providing means for more effectually
securing and retaining the vulcanised india-rubber or pneumatic washer or valve
employed for the purpose. The said vulcanised, india-rubber or pneumatic washer or
valve is secured to the top side of the palate by a hollow tube provided with a closed
end or solid head.
In carrying out my invention I form a hole in the denture or palate in which is
fixed an annular metal tube which allows of the open end being closed in an efficient
manner by a punch or a pair of grips; the pneumatic washer or valve being secured
in position by the solid head of the said tube.
..
My invention may be adapted to dentures or palates of vulcanite, platinum, or any, 1
of the materials used for the purpose in dentistry.
Fig. 1 is a plan of the roof side of a palate with my improvement applied-Fig. 2
is a sectional elevation through line A. B. Fig. 3 is an enlarged sectional view of my
improved hollow tube before being fixed in the palate, and Fig. 4 is an enlarged
sectional view of the pneumatic washer. or. valve secured to the palate by the said
hollow tube.
The washer or valve C is secured to the top side of the palate D by the hollow
tube E; the latter being provided with the closed end or solid head G, which secures
the washer, or valve C-in position. After the hollow tube E has been passed through
the washer or valve C and the palate D the open end H is bent or rivetted over-as in
Figs. 2 and 4 by a punch or a pair of grips.
In adapting my invention to a bottom set of artificial teeth the palate or denture is
provided on each side with the washer or valve C; being secured by the hollow tube E.
The tube E in this case is provided with the oblong head G as shown in Fig. 5.

page_text: The advantages accruing from this invention are that the pneumatic washer or valve
is more firmly secured than hitherto owing to the easy method it allows for punching
or gripping; also that it minimises the risk of cracking or damaging the denture or
plate when fixing.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
The use and construction of the hollow open ended tube E with the closed end or
solid head G for the purpose herein described and set forth.
