Appliances.
ALBION JETHRO LARDENT Medical Herbalist 321 Southwark Park Road
Bermondsey London, S.E. do hereby declare the nature of this invention to be as
follows:-
The drift of my improvement is to enhance, while ensuring free and continuous
ventilation, an absolute sanitary condition of all parts and thorough cleanliness and
sweetness of portions in immediate contact with the lips and mucous membranes.
Being a perfect regulator it prevents an undesirable access of air to the tubes, and
by its present construction it can be cleansed effectually without the usual difficulties
which are attendant in existing manufactures of non-suffocating shields.
The invention consists in the simple formation of grooves radiating from the
central hole to the extreme border on the lower or inner surface of the appliance
in immediate proximity to the respiratory organ.
To regulate freedom of breathing the number and size of grooves can be
increased or diminished in any desirable manner. By adopting eight grooves,
sixteen openings are produced for access of air at the centre and extremities
respectively.

ALBION JETHRO LARDENT Medical Herbalist, etc., 321, Southwark Park Road
Bermondsey London, S.E. 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:-
These improvements on existing shields for teething teats, soothers and similar
medical appliances are intended to propitiate the ability of the child to breathe
during prolonged use of the same, and still more especially to enable ready
cleansing of all surfaces by ensuring smoothness and ready access to all portions
in cleansing, thereby ensuring a permanent and absolute sanitary condition as well
as perfect sweetness of the apparatus in use, and to maintain the desired strength
of the shield.
Fig. I shows the side of a shield applied to feeding bottles, etc. intended for
immediate contact with the lips. Around b.-which is the hole for the india-rubber
tube to pass through-the shield is somewhat strengthened through the increased
thickness as shown in the section. The grooves e. are continued vertically at the
extreme exterior border and at b., thus extending to the upper side of the shield
in a smooth and even form. In adopting this plan all the intermediate parts
between the grooves form the U shape. The section of the grooves radiating
horizontally may be of a U shape, crescent, or in any desired form.
Fig. I represents a shield for feeding bottles, etc. with a doubled number of
horizontal and radiating grooves, cut and evenly to facilitate cleansing. Half of
this number extend half way only, and communicate with the centre through the
circular groove d. and the longer radiating grooves. The shield in strengthened in
the same manner as shown in Fig. II and Fig. I.

page_text: Fig. III is a section of an oval-shaped shield for feeding bottles, etc., to which
the principle of the above radiating groove can be applied in like manner.
Fig. IV is a flat shield intended for the same improvement.
These shields can be produced in bone, porcelain, china, vulcanite, wood or
similar innocuous materials. The form of grooving may in all instances be as
described in Figs. I and II.
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 :-
1st. A shield for feeding bottles, teething pads, soothers, and the like articles,
and which shields are provided with horizontal grooves, the section of which may
either be crescent, U shape or assume any other form, and radiate from the centre
to its extreme border on the side opposed to the grooves, as described directly in
Fig. I, and indirectly in Fig. II.
2nd. An increased thickness of the grooved shield on the grooved side for a short
distance from the centre to protect the shield against easy breaking, thereby
preventing accidents and loss.
3rd. Circular grooves in addition to the radiating grooves in order to facilitate
still more the conveyance and free passage of air.
Dated this the 26th day of April 1893.
