page_text: LETTERS PATENT to Peter Jensen, of 33, Chancery Lane, London, for the
Invention of "IMPROVEMENTS IN WASH BOARDS." A communication from
abroad by Jamies Morris Davies, of the City of Hamilton, in the County of
Wentworth, in the Province of Ontario, Dominion of Canada, Machinist.
aled the 23rd April 1880, and dated the 25th October 1879.
PROVISIONAL SPECIFICATION left by the said Peter Jensen at the Office
of the Commissioners of Patents on the 25th October 1879.

PETER JENSEN, of, 33, Chancery Lane, London.
BOARDS." (A communication from abroad by Jainies Morris Davies, of the City of
Hamilton, in the County of Wentworth, in the Province of Ontario, Dominion of
Canada, Machinist.)
The Invention has for its object to construct an ordinary wash board entirely of
zine or sheet metal, the present form of wooden frame and metal or corrugated
board being preserved, and this Invention consists in constructing the frame of a
wash board of sheet metal bent to a tubular form mitered and soldered together at
the rectangular head and slotted at the sides to receive the rubbing board or
corrugated zinc, and the plain portion at the head of the board, which parts are
preferable, of one piece of sheet metal, and the sides are held from splaying by
tubular bars soldered transversely to the sides at back and front at the intersection
of the plain and corrugated portions.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
"
the said Peter Jensen in the Great Seal Patent Office on the 24th April 1880.

Hamilton, in the County of Wentworth, in the Province of Ontario, Dominion of
Canada, Machinist.)
The Invention has for its object to construct an ordinary wash board entirely of
zinc or sheet metal, the present form of wooden frame and metal or corrugated

page_text: board being preserved, and this Invention consists in constructing the frame of a
wash board of sheet metal bent to a tubular form mitred and soldered together at
the rectangular head and slotted at the sides to receive the rubbing board or
corrugated zinc and the plain portion at the head of the board, which parts are
preferable of one piece of sheet metal, and the sides are held from splaying by
tubular bars soldered transversely to the sides at back and front at the intersection
of the plain and corrugated portions.
Fig. 1 of the Drawing represents an elevation of my wash board partly in
section.
Fig. 2 is a vertical section. A is the rectangular frame which is formed tubular
of an oval shape in section by bending zinc or other sheet metals, the edges closing
together at the foot portion b.
The tubular sides and head of the board are mitred and soldered; the sides are
held from splaying by tubular metallic bars of sheet metal B, B, (which also act as a
convenient soap ledge). back and front soldered to the sides at the head at the
junction of the plain and corrugated portions of the rubbing surface, both of which
portions, preferably, are of sheet metal, the edges held by insertion between the
edges of the frame A, and soldered thereto if desired.
The portion of the frame A to receive the corrugated portion of the washing
surface is cut away sufficiently before bending to allow of its insertion between the
edges.
The lower edge of the washing surface or board d is reinforced by a tubular
bar which at the ends is secured to the frame A, and prevents the latter from
splaying.
In order to cause the sides of the board to retain their shape, a piece of wood c of
corresponding form grooved longitudinally on the inside centre is inserted up each
tube, which also acts as a strengthening bearing for each side of the zinc rubbing
board d.
The top horizontal part of the tubular frame A bas also a piece of wood c¹ inserted
in it (ungrooved) to retain its form.
Having now described the nature of the said Invention and in what manner the
same is to be performed, I declare that I claim as the aforesaid improvements in
washboards,
1st. As an improved article of manufacture a metallic washboard having a sheet
metal frame A bent to a tubular form mitred and soldered at the head and stayed
by the tubular bars B, B, and the rubbing surface of sheet zinc plain and corrugated
having its side and top edges interposed and held fixedly by edges of the tubular
frame secured at the ends of the frame A, as set forth.
2nd. The metallic frame A having a metallic rubbing or washing surface d,
suitably corrugated or crimped for the purpose set forth.
3rd. The combination of the tubular metallic frame A and the grooved wood
filling piece c or its equivalent, substantially as and for the purpose specified.
In witness whereof, I, the said Peter Jensen, have hereunto set my hand
and seal, this Twenty third day of April, in the year of our Lord One
thousand eight hundred and eighty.
