PROVISIONAL SPECIFICATION left by the said Levi Parsons Merriam
at the Office of the Commissioners of Patents, with his Petition, on
the 29th January 1874.
I, LEVI PARSONS MERRIAM, of Leadenhall Street, in the City of
London, do hereby declare the nature of my said Invention for "In-
PROVEMENTS IN MACHINERY, OR APPARATUS FOR SOLDERING METALS," to be as
follows:-
This Invention relates to improvements in machinery or apparatus for
soldering metals, and consists in an apparatus capable of holding the
can, canister, or other article to be soldered upon an inclined or hori-
zontal revolving shaft, whilst the pot or vessel containing the metal for
soldering is held by or supported upon another portion of the apparatus
in such a position that the can, canister, or other article to be soldered

page_text: will be so held upon or by the revolving shaft as to be caused to come
into contact with the melted solder at the parts required to be soldered
during its revolution.
The article to be soldered may also work against a piece of wrought
iron or other suitable metal placed in such a position with regard to the 5
solder as to act as a heater and scraper or smoother.
The can or other article to be soldered may be held in position by
discs, clasps, or springs, in place of or in conjunction with the revolving
shaft, as herein-before described.
The not containing the liquid solder may also be made adiustable, so 1
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Levi Parsons Merriam in the Great Seal Patent
Office on the 27th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEVI 1
PARSONS MERRIAM, of Leadenhall Street, in the City of London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of January, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty- 2
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Levi Parsons Merriam, Her special license
that I, the said Levi Parsons Merriam, my executors, administrators,
and assigns, or such others as I, the said Levi Parsons Merriam,
my executors, administrators, or 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
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SOLDERING METALS," upon :
the condition (amongst others) that I, the said Levi Parsons Merriam,
my executors or administrators, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the nature of

page_text: the said Invention, and in what manner the same was to be performed,
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 Levi Parsons Merriam, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say:-
This Invention relates to improvements in machinery or apparatus for.
soldering metals, and consists in an apparatus capable of holding the
can, canister, or other article to be soldered upon an inclined or hori-
zontal revolving shaft, whilst the pot or vessel containing the metal for
soldering is held by or supported upon another portion of the apparatus
in such a position that the can, canister, or other article to be soldered
will be so held upon or by the revolving shaft as to be caused to come
into contact with the melted solder at the parts required to be soldered
during its revolution.
The article to be soldered may also work against a piece of wrought
iron or other suitable metal, placed in such a position with regard to tho
solder as to act as a heater and scraper or smoother.
The can or other article to be soldered may be held in position by
discs, clasps, or springs, in place of or in conjunction with the revolving
shaft, as herein-before described.
The pot containing the liquid solder may also be made adjustable, so
as to allow any size of article to be soldered.
And in order that my said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that purpose
shall refer to the several Figures on the annexed Sheet of Drawings,
the same letters of reference indicating corresponding parts in all the
Figures.
Figure 1 is a side sectional elevation of my improved soldering
apparatus.
A represents a frame or stand mounted over the base of the apparatus,
and adjustable vertically on the screws B, B, by means of nuts, as

page_text: shewn. At the top of the frame A is a vessel or tank C, containing the
metal for soldering, which is melted by the heat from the lamp D,
placed immediately beneath the said vessel or tank in a convenient
position inside the frame or stand A, as shewn; or in lieu of the lamp D
a furnace may be employed for melting the soldering metal. E is an
upright or standard fixed to the base of the apparatus at some distance
from the frame or stand A. To the upper end of this upright or standard
is hinged a bracket F, formed at its outer end with bearings G, G, in
which fits a shaft or holder H capable of revolving, the said shaft or
holder being formed at its inner end with a cup or socket h, in which
the can, canister, or other article to be soldered is placed, and is held by
one of the arms of a lever x, which arm is caused to press hard against
(and so retain) the can or other article in its seat by the action of a
spring y against the under side of the other or opposite arm of the said
lever, as shewn; or the can, canister, or other article may be held in its
seat by discs, clasps, or any other suitable device.
The shaft or holder H with the can, canister, or other article to be
soldered are caused to revolve together by any suitable power, and either
horizontally or inclined, in such a manner that during an entire rovo-
lution the edge to be soldered of the said can or other article will be in
contact with the soldering metal contained in the vessel or tank C. To
effect this the side of the latter is formed with a circular concave bed or
edge c, the lowest portion of which is on a level or nearly so with the
said metal. On this bed the can, canister, or other article is placed, so
that the edge or part thereof to be soldered overhangs or dips into the
melted metal, the bed meanwhile during the revolution of the can,
canister, or other article acting as a heater, scraper, or smoother to the
edge or part being soldered. K is a rod attached at its upper end to one
side of the hinged bracket F, as shown, and at its lower end to a treadle,
not represented on the Drawing; z is a spring connected at its upper
end to the other side of the hinged bracket F, and at its lower end to the
upright or standard E.
The can, canister, or other article to be soldered is presented to the
melted metal contained in the vessel or tank C by depressing the treadle
on the rod K, which pulls over the hinged bracket F and inclines the
shaft or holder H until the said can or other article carried thereby is in
contact with the circular concave bed or edge c, as before described.

page_text: The can, canister, or other article is withdrawn from the melted metal
by relieving the pressure from the treadle, which causes the spring z to
bring back the shaft or holder H with the said can or other article to
their original position.
By adjusting the height of the frame or stand A any size can, canister,
or other article to be soldered can be introduced to the machine, and the
inclination of the shaft or holder H regulated at pleasure.
Any convenient number of shafts or holders similar to H may be
employed in this apparatus, the mode of operation being the same in
each case.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that what I consider
to be novel and original and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent is,―
First. In a soldering apparatus the construction and arrangement of a
revolving shaft or holder for holding a can, canister, or other article to be
soldered in combination with the vessel or tank containing the soldering
metal, and carried by a vertically adjustable frame or stand, substantially
as and for the purposes herein-before described and illustrated by my
Drawing.
Second. The application and use of a hinged bracket in combination
with a revolving shaft or holder for holding a can, canister, or other
article to be soldered, and with an upright or standard fixed to the base
of a soldering apparatus, substantially as and for the purpose herein-
before described and illustrated by the accompanying Drawing.
In witness whereof, I, the said Levi Parsons Merriam, have to
this my Specification set my hand and seal, the Twenty-seventh
day of July One thousand eight hundred and seventy-four.
L. P. MERRIAM. (L.S.)
