Ventilated Thimble.
FREDERICK WALLACE KITTO 56 Claybrooke Road Fulham Palace Road
Fulham, in the County of Middlesex, Engineer WALTER KITTO 56 Claybrooke
Road Fulham Palace Road, Fulham, in the County of Middlesex, Engineer, do
hereby declare the nature of this invention to be as follows:-
An improved sewing thimble by which the air is kept in circulation around the
encased portion of the finger, thus keeping the finger perfectly ventilated.
We claim, firstly for this invention the circulation of air in the inside of the
thimble, while on the finger, secondly the thimble may be made of metal or any
other suitable material, the thimble can be corrugated, so as to allow the air to pass
freely around the encased portion of the finger, or a corrugated or perforated liner
may be made and inserted inside an ordinary thimble, or any other device that will
cause the free circulation of air inside the thimble, while on the finger.

Ventilated Thimble.
We, FREDERICK WALLACE KITTO, 56 Claybrooke Road, Fulham Palace
Road, Fulham, in the County of Middlesex, Engineer, WALTER KITTO,
56 Claybrooke Road, Fulham Palace Road, Fulham, in the County of Middlesex,
Engineer, do hereby declare the nature of our 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 our invention is to manufacture sewing thimbles in such a manner
that a free circulation of air may be provided for between the finger and the wall
of the thimble.
We effect this improvement by corrugating or perforating, or corrugating and
perforating the liner or the surface in contact with the finger, whereby air is capable
of passing between such corrugations and through such perforations, and also between
the wall of the thimble and the finger. The passage of air thus provided for
prevents the finger becoming heated, and also prevents the uncomfortable result of
the thimble adhering to the finger, and the irritation arising therefrom.
The corrugations may be annular or longitudinal, and may be formed in the wall
of the thimble, or in a lining introduced thereinto, and such lining may consist of
similar material to the wall of the thimble, or of any suitable dissimilar material,
and may be united thereto by riveting or soldering, or by means of any suitable
adhesive material, or by spinning the lower edges together, one over the other.
And in order that our said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar figures of reference indicate corresponding parts.
Fig. 1 is an elevation, partly in section, illustrating one form of our invention,
in which a liner with longitudinal corrugations is fitted inside the thimble.
P

page_text: Fig. 2 18 a separate view of the liner.
Fig. 3 is a section on the line 9-9 of Fig. 1.
Fig. 4 is a view of the underside of Fig. 1.
Fig. 5 is an elevation showing a corrugated thimble, without any liner.
Fig. 6 shows a method of fitting a liner with horizontal corrugations inside the
thimble.
Fig. 7 shows a thimble fitted with a corrugated liner with an open top.
Fig. 8 is a vertical section of a thimble with horizontal corrugations, without any
liner.
The thimble 10, shown in Figs. 1, 3, 6 and 7, may be of the usual pattern, but
rather larger in diameter to afford space for the liner 11. The top of the liner
shown in Figs. 1, 2, 3, 4 and 6, is perforated with air vents 12, and the lower
flanges are similarly perforated at 13; any number of such holes being made to
ensure the circulation of the air, and the top being, in some cases, entirely open, for
the same purpose.
The construction of the corrugated thimbles will be readily understood from
the drawings. The corrugations may be very much varied in length, depth,
sectional form and otherwise. Or the liner may be merely perforated, without
corrugations.
•
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The improved construction of thimbles, in which the contact of the finger is
confined to certain parts of the internal walls of corrugated linings fitted inside the
thimbles, or of similar points of contact in the thimbles themselves, or of perforated
linings without corrugations, for the purpose of permitting the free circulation of
air round the enclosed portion of the finger, substantially as herein before described
and illustrated by the drawings.
