PROVISIONAL SPECIFICATION.
An Improved Process for the Jointing or Soldering of Whalebone.
1, JOSEPH BOURUMEAU of 55 Rue Aumaire, in the City of Paris, Republic
of France, Manufacturer of Shell Combs, do hereby declare the nature of my
invention to be as follows:-
Many attempts have been made to solder or join whalebone, by reason of the
considerable value of the material, but none of these attempts have given practical
results from the point of view of a thorough binding joint, end to end of the parts
assembled together.
My invention relates to a new process of soldering or jointing and consists more
especially in the application of a special agglutinative composition.
This composition is a paste or glue obtained by means of powder of celluloid or
of one or other of its derivatives dissolved by means of an appropriate solvent such
as ether or ethyl alcohol, separately or mixed, caustic soda acetic acid, alcohol or
other suitable substances.
In the case when acetic acid is employed as the solvent, the proportions that
nave given the best results are as follows:-
nave given the best results are as follows:-
Powder of celluloid
Acetic acid
200 grammes.
1 litre.
I only give these proportions nevertheless as an example, reserving to myself the
right to modify them according to the requirements of the various cases that occur
in practice.
This composition is coloured by ordinary means according to the colour of the
whale-bone to be soldered, and where it is a matter of soldering white whale-bone
I employ by preference the powder of celluloid ivory.
I may equivalently substitute for the celluloid, cellulose in all its forms and
obtain the same result.
To apply my process, the ends of the whale-bone to be soldered or joined, are
first conveniently cut and thinned down so that a uniform thickness is preserved at
the joint equivalent to the other part of the whalebone.
The extremities thus prepared are plastered with the composition herein before
described, brought together and maintained under pressure, the necessary time, to
complete the setting of the composition.
The bits or blades of whale-bone thus jointed are then dried by being submitted
to the ordinary operations of drying, of polishing, dressing etc., in a word to the
finishing of the product.
I reserve to myself the right to apply all convenient means of applying pressure
and of drying to effect my jointing of whalebone.
The whale-bone thus treated by my process is rendered applicable to the manu-
facture of all articles and notably the handles of whips, sticks, and other articles,
in which whale-bone cannot be employed by reason of its dimensions and its high
price.
Dated this 27th day of December 1893.

I, JOSEPH BOURUMEAU of 55 Rue Aumaire, in the City of Paris, Republic
of France, Manufacturer of Shell Combs, do hereby declare the nature of my
invention, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
Many attempts have been made to solder or join whale-bone by reason of the
considerable value of the material, but none of these attempts have given practical
results from the point of view of a thorough binding joint, end-to-end, of the parts
assembled together.
My invention relates to a new process of soldering or jointing, and consists more
especially in the application of a special agglutinative composition.
This composition is a paste or glue obtained by means of powder of celluloid, or
of one or other of its derivatives, dissolved by means of an appropriate solvent,
such as ether, or ethyl-alcohol, separately or mixed, caustic soda, acetic acid,
alcohol, or other suitable substances.
In the case when acetic acid is employed as the solvent, the proportions that
have given the best results are as follows:-
Powder of celluloid
Acetic acid
200 grammes.
1 litre.
I only give these proportions nevertheless as an example, reserving to myself
the right to modify them according to the requirements of the various cases that
occur in practice.
This composition is coloured by ordinary means, according to the colour of the
whale-bone to be soldered, and when it is a matter of soldering white whale-boue,
I employ by preference, the powder of celluloid ivory.
I may equivalently substitute for the celluloid, cellulose, in all its forms, and
obtain the same result.
To apply my process, the ends of the whalebone to be soldered or joined, are
first conveniently cut and thinned down so that a uniform thickness is preserved at
the joint, equivalent to the other part of the whale-bone.
The extremities thus prepared are plastered with the composition herein before
described, brought together, and maintained under pressure, the necessary time, to
complete the setting of the composition.
The bits or blades of whale-bone, thus jointed, are then dried by being submitted
to the ordinary operation of drying, of polishing, dressing etc.; in a word, to the
finishing of the product.
I reserve to myself the right to apply all convenient means of applying pressure
and of drying, to effect my jointing of whale-bone.
The whale-bone, thus treated by my process, is rendered applicable to the manu-
facture of all articles, and notably to the handles of whips, sticks, and other
articles, in which whale-bone cannot at present be employed by reason of its
dimensions and its high price.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A process for the jointing or soldering of whale-bone, consisting of uniting parts
of whale-bone by means of a glutinous paste composed of powder of celluloid or

page_text: other cellulose, dissolved in acetic acid; and rendering this collar hard and firm by
pressure, until the joint has seized and set, substantially as and for the purposes
herein described.
