PROVISIONAL SPECIFICATION left by the said William Edward Gedgo
at the Office of the Commissioners of Patents, with his Petition,
on the 9th January 1869.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son,
of No. 11, Wellington Street, Strand in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "In-
PROVEMENTS IN THE MANUFACTURE AND MORE PARTICULARLY IN THE CLOSING OF
TINS OR BOXES FOR PRESERVING PROVISIONS AND FOR OTHER USES, TOGETHER WITH
IMPROVED MACHINERY OR APPARATUS FOR EFFECTING THE SAME," a communi-

to leakage, therefore to complete this fastening and secure a close and firm
adhesion of the folded portions they are submitted to powerful pressure,
which crushes the clasping and thus tightens all the parts. This work is
accomplished by means of a socond horizontal milling tool moveable on the
first, and only coming into action when this latter is no longer required.

The operation of compressing the clasping therefore takes place as
follows:-Tho milling tool retiring in consequence of the displacement
of the milling tool o leaves another profilo in combination with that of
the milling tool p to effect this crushing. The vertical milling tool
does not change its position further than rising to the height of the
profile of the milling tool o. Fig. 2 represents this oporation..
Wo now return to the machine of which Fig. 1 is a side view.. The
upward movements of the milling tool p are regulated by means of the
lever q and counterweight which act according to the contour of the
cam A (Fig. 1). Tho connoxion which must exist in the movements of
the milling tools is best secured by combining them. Thus the shaft i
carries a'pinion o', which sets in motion the toothed wheel B, on the
axle of which is set, the cam A, this same pinion c³ also gearing with
another toothed wheel E, this latter giving motion to a cam D, by which
the action of the two milling tools 12, o, is regulated. Fig. 7 (Sheet II.)
represents the movement thus produced.
It has been above stated that the milling tool o obeys two cams, and
I will now explain how these cams are set in motion. The cam D in its
rotary movement lifts the lever F, thereby causing the pivoting of the
shafts on which one of the two cams & is set. This movement is then
conveyed to the other by two sectors g", h", gearing with each other,
and both set on the shaft 8.
The closing of a box is accomplished as follows:-The box is placed
on the plato n, which is moveable under the action of a biconical spring.
The movement given by the crank handle to the fly wheel of the shaft i
sets in action the toothed wheels O, O', g, g', which move the milling
tools; this same movement is conveyed to the cams A, D, by the toothed

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 11,
Wellington Street, Strand, in the County of Middlesex, Patent Agent,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of January, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Edward Gedge, Her
special licence that I, the said William Edward Gedge, my executors,
administrators, and assigns, or such others as I, the said William Edward
Gedge, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "I■.
PROVEMENTS IN THE MANUFACTURE AND MORE PARTICULARLY IN THE CLOSING OF
TINS OR BOXES FOR PRESERVING PROVISIONS AND FOR OTHER USES, TOGETHER WITH
IMPROVED MACHINERY OR APPARATUS FOR EFFECTING THE SAME," a communication
to me from abroad by Edmond Jean Bourgine, of 39, Faubourg St.
Martin, Paris, France, upon the condition (amongst others, that I,
the said William Edward Gedge, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was fo be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said William Edward Gedge, do hereby
declare the nature of the said Invention, and in what manner the same is

page_text: to be performed, to be particularly described and ascertained in and 'by
the following statement :--
The machine illustrated on the accompanying Sheet of Drawing:
forming part of this Specification is specially constructed for closing tins¸
containing provisions, as also other boxes, by clasping and setting together
the edges of the lid and of the body of the box, so that they form as it
were but one piece, the operation of soldering them together being thus
dispensed with. This clasping leaves nothing to desire as regards
adhesion and hermetic closing, which are so thoroughly effected that no.
leakage can occur when the boxes are submitted to the operation of
boiling. The whole of the clasping is effected by this machine, which by.
means of compressing or milling tools, wheels, or rolls set as herein-
after described so bends and folds together the tin of the lid and of
the body of the box that these become united in an inseparable

page_text: position the box is certainly closed, but nevertheless it is still exposed
to leakage, therefore to complete this fastening and secure a close and
firm adhesion of the folded portions they are submitted to a powerful
pressure which crushes the clasping and thus tightens all the parts. This
work is accomplished by means of a second horizontal milling tool
moveable on the first, and only coming into action when this latter is
no longer required.
Fig. 6 gives an idea of this displacement and of the manner in which
it takes place, two cams s', s¹, sct on two shafts 8, 8, act upon a collar »
coming against a shoulder on the milling tool o. The red lines
indicate this movement and the respective position of the milling
tolls 1 and o.
22
The operation of compressing the clasping therefore takes place as
follows:-The milling tool » retiring in consequence of the displacement
of the milling tool o leaves another profile in combination with that of
the milling tool p to effect this crushing. The vertical milling tool
does not change its position further than rising to the height of the profile
of the milling tool o. Fig. 2 represents this operation.
We now return to the machine of which Fig. 1 is a side view. The
upward movements of the milling tool p aro regulated by means of the
lever q and counterweight G, which act according to the contours of the
cam A (Fig. 1). The connexion which must exist in the movements of
the milling tools is best secured by combining them. Thus the shaft i
carries a pinion c" which sets in motion the toothed wheel B, on the axle
of which is set the cam A, this same pinion c" also gearing with another
toothed wheel E, this latter giving motion to a cam D by which the
action of the two milling tools n, o, is regulated. Fig. 3 represents this
movement.
It has been above stated that the milling tool o obeys two cams, and
I will now explain how these cams are set in motion. The cam D in its :
rotary movement lifts the lover F', see Fig. 3, thereby causing the pivoting
of the shafts on which one of the two cams a' is set. This movement
is then conveyed to the other by two sectors g", ", gearing with each
other and both set on the shafts 8.
The closing of a box is accomplished as follows:-The box is placed
on the plate " which is moveable under the action of a biconical spring
on his 1 and 21

page_text: The movement given by the crank handle K to the fly wheel m of the
shaft sets in action the toothed wheels O, O', 9, 9', which move the
milling tools; this same movement is conveyed to the cams A, D, by
the toothed wheels B, c", E, and the result of the action of these various
parts has been above explained.
Claim is made to the use of a machino serving to close boxes or tins
containing preserved provisions and also other boxes without soldering,
that is to say, this Invention replaces the soldering by a clasping of lid.
and body effected by means of milling tools or wheels, the movement
and action of which have been herein-before explained, and results
from the combination of this machine, substantially as herein set forth
and illustrated on the accompanying Sheet of Drawing.
In witness whereof, I, the said William Edward Gedge, have
hereunto set my hand and' seal, this Eighth day of July, in
the year of our Lord One thousand eight hundred and sixty-
nine.
