I, THOMAS FRANK LYNCH of Aldersgate Street, in the City of London, Druggists
Sundriesman, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to produce an enema with valves and valve fittings
capable of resisting the action of any fluids that may be passed therethrough and of
being readily removed and cleansed when necessary.
For this purpose I construct the valve fitting of a generally cylindrical form as
heretofore so as to pass into the enema tube or pipe but instead of forming it of metal
or vulcanite as has been common in such class of instruments I according to my
invention form the valve and valve fitting entirely of glass.
In constructing valves and their fittings according to my invention I preferably
take a suitable length of glass tube and by the aid of the blow pipe form a seat for the
valve at one end thereof; I then introduce a glass valve into the length of tube, in
which I now form one or more indents in such a position as to retain the valve within
the tube and yet allow of the proper degree of motion thereto.

page_text: Figure 1 is a longitudinal section of a portion of an
invention.
enema illustrating my
Figure 2 is a similar view of the valve and valve fitting separately and Figure 3 is
a cross section thereof taken on the line A. B. of Figure 2.
Figure 4 is a side view of the valve and valve fitting, and Figure 5 is a plan
thereof.
In the several figures of the drawings similar parts are marked with like letters of
reference.
a represents a portion of an enema tube, and 6 represents the usual metal fitting,
which is provided at its end with a grating bl.
c represents the valve fitting, which is constructed of a generally cylindrical form
as heretofore so as to pass smoothly into the enema pipe or tube a, but instead of
forming such valve fitting of metal or vulcanite, as has been common in such class of
instruments, I, according to my invention, form the valve fitting c and valve d entirely
of glass.
In constructing the valve d and fitting e according to my invention I preferably
take a suitable length of glass tube and, by the aid of the blow pipe, form a seat c¹ for
the valve dat one end thereof by turning in or compressing the edge of the tube all
round.
I then introduce into the other end of the length of glass tube a glass valve d which
may be of the form shown in the drawing or of cylindrical or other suitable form and,
after having thus introduced the valve d into the tube c, I form one or more indents c²

page_text: in such tube in such position and so proportioned as to retain the valve d within the
tube c and yet allow of the proper degree of movement thereto and the passage of the
fluid in the action of the enema.
By means of my invention I obtain an enema provided with valves and valve
fittings which are capable of resisting the action of any fluids that may be passed
therethrough, and which at the same time may, when necessary, be removed from,
cleansed and replaced in, the enema tube with the greatest ease.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
--
1. An enema provided with a glass valve fitting c and valve d in manner
substantially as herein shown and described and for the purpose stated.
2. An enema valve d and fitting c constructed entirely of glass substantially as
herein shown and described and for the purpose stated.
3. An enema valve d and fitting c constructed entirely of glass, the fitting being
formed of a length of glass tube, which is, by the aid of heat, compressed or turned in
at one end thereof to form a seat c¹ for the valve d and which is contracted at or near
the other end thereof after the introduction of the valve d in order to retain the
valve d therein and yet allow of the proper degree of movement to such valve and the
passage of the fluid in the action of the enema all in manner substantially as herein
shown and described and for the purpose stated.
