Improvements in Combs.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake and Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex 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:—
This invention relates to improvements in combs, and in the manufacture thereof,
the object being to produce a durable, strong and sightly comb which is believed to
be superior to any cheap comb at present known, and more economically produced
than by the ordinary methods.
It has heretofore been customary to strengthen the heads or backs of combs with
metal tubing pressed on to the back of the comb, and a re-enforce has been formed
of cast metal, but there are objections which are not unimportant to all the methods
heretofore practised. If the re-enforce is formed of sheet metal and attached by
pressure, there is constant danger of its displacement, whereby the value of the
comb is destroyed; the cost of production is very considerable, and if the re-enforce
is made of thin tubing or metal, it is easily sprung out of place and the comb is not
as strong as is desirable.
The distinctive novelty of the invention consists in fastening a re-enforce of
rolled or sheet metal tubing to the back of the comb by means of molten metal, as
hereinafter more fully described, whereby an effective and permanent and superior
attachment is accomplished, and an improved and superior comb produced at
reduced expense.
In practice, the objects of the invention may be accomplished in any convenient
way, the only essential consideration being that the metal is introduced within the
re-enforce and permitted to cool. Any suitable or convenient form of mould may
be used, or the metal may be reduced to a molten state and introduced by dipping,
or the introduction may be accomplished in some other way.
It may also be expedient to form a longitudinal notch or undercut groove upon
the back of the comb, and to fit the re-enforce therein and then introduce the
molten metal into the re-enforce, whereby a very effective connection of the parts
is accomplished.
I make use of any suitable metal or alloy such as lead, or alloys consisting of
lead and tin, or I may use any metal or alloy which can be conveniently reduced to
a molten state and introduced within the re-enforce.
In the accompanying drawings I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a view showing a form of mould or pouring expedient which may be
availed of in practising the invention.
Figures 2, 3 and 4, are sectional views of my improved comb showing preferred
forms of the invention.
In Figure 1 I have shown half of a two-part mould which may be used in
practising the invention, in which F represents half of the mould which is provided
with the funnel-shaped orifice G, and in connection with which a corresponding
half, provided with a like orifice is employed. A represents the toothed part of
the comb; B the back, and D the re-enforce of sheet metal. The comb is placed
in position, as indicated being secured in any convenient and appropriate manner,
and the metal is poured or introduced into the orifice G, entering the re-enforce
and effecting the connection of the parts.

page_text: In Figures 2, 3 and 4, A represents the tooth of the comb B, the back C, a
longitudinal groove or notch; D the re-enforce, and E the filled part of poured
or molten metal. But as has been stated, while the use of the groove or notch
is important and expedient, it is not an essential feature, and may be omitted.
The re-enforce will be made of any of the sheet metals now in use, and will be
of any preferred and appropriate size, shape and configuration, the only essential
consideration being that a sufficient space be left within the re-enforce and between
it and the back of the comb to permit the molten metal to enter and effect the
desired attachment. I recommend that the re-enforce be filled from end to end, so
that the whole back of the comb will be strengthened and solidified.
By preference I make use of a comb formed of horn, but I may make use of any
other suitable material, including metal.
While I prefer to make use of the retaining groove, and recommend its employ-
ment as ensuring satisfactory results, it may be dispensed with, if desired, in which
event the tubing or metal will be placed in position and the molten metal
introduced to all intents and purposes the same as when the retaining groove
is used.
Any suitable metal may be used, and it may be introduced in any convenient
way.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent I declare that what I claim is :-
The improved comb constructed substantially as hereinbefore described and
shown in the drawing.
