Improvements in Dust-pans.
1, HERBERT JOHN ALLISON, of 52 Chancery Lane, London, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, which has
been communicated to me from abroad by William Fletcher Spurgin, of West Point,
County of Orange, State of New York, United States of America, Captain in the
United States Army, and in what manner the sime is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention consists in a dust-pan constructed in the form, and having the
parts and devices, hereinafter shown and described and as more particularly recited
in the claim.
Figure 1 is a plan view in perspective of a dust-pan containing my invention; and
Figure 2 is a longitudinal vertical section of the same:
In constructing a dust-pan in accordance with my invention I form a trough-like
receptacle A the bottom a of which is concavo-convex, or of an equivalent shape so
as to constitute a crown or apex extending laterally of the pan upon which the
receptacle A may rest and may be tilted forwardly and rearwardly, as shown, and
the sides a of which are preferably vertical, as shown. From the forward edge of
this receptacle A a downwardly inclined plate, or platform B extends, with its outer
or lower edge b substantially in line with the apex or crown of the convex bottom a¹
of the receptacle A. At the juncture of the plate B with said forward edge of the
receptacle A the plate is desirably bent or curved, flatwise, rearwardly and downwardly
to meet said edge, as shown at 6¹.
It is obvious that the concavo-convex bottom a¹ and the plate B may be formed
in one piece of metal in the shape shown and described and with the bend at the
place stated.
The inclined plate B is preferably wider at its outer or lower edge than at its
juncture with the receptacle A, as shown; and the plate has the upwardly extending
flanges on its side edges, which flanges join the side pieces of the receptacle A, as
shown.
C is a plate having perforations c in it, and preferably constituted of a piece of
comparatively coarse-mesh wire-netting, as shown, so that the perforations extend
throughout said plate. This plate C extends from the line of the juncture of the
plate B with the edge of receptacle A, and preferably in the same plane as the plate B,
over the receptacle A to about midway between the front and rear edges of said
receptacle, between the sides thereof, and has its rearward edge c¹ desirably bent or
curved downwardly flatwise, as shown.
Upon the rearward side of the receptacle A, the usual handle D may be fixed,
as shown.
The advantages accruing from my invention are that in gathering up the dust and
debris to be collected in the pan by means of a broom, the material swept upon and
upward over the platform B will pass to and over or through the plate C into
receptacle A; and also that, while the larger objects or particles will pass entirely
over the plate C and thus into said receptacle, the finer particles and dust or fibres
which have a tendency to adhere to the broom will be scraped off or detached therefrom
by the passing of the broom over the plate Cand be carried over or down through said
plate Cinto said receptacle A.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
claim is:
A duct nan comanoad of the franah like recentacle A having the described bottom at

page_text: the inclined plate B extending forwardly and downwardly from the front edge of sand
receptacle with its lower edge b substantially in line with the crown or apex of said
bottom of said receptacle, and the perforated plate extending from the juncture of
said platform with said edge of said receptacle to a line substantially midway of the
front and rear edges thereof, as and for the purpose specified.
Uoted this 16th day of July 1889.
