page_text: Letters Patent for the same, and havo mado solemn Declaration that it
has been communicated to me from abroad by Joseph Baker, of Trenton,
Canada, Gentleman.
NOW KNOW YE, that I, the said George Haseltine, do hereby
declare that the following Complete Specification, under my hand and 5
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following.
statement, reference being had to the accompanying Drawing forming
a part of this Specification :-
This Invention consists in making the bottom of the scoop removable, 1
and providing a scries of interchangeable sieves, colanders, and the like
to be used in place of the bottom; in providing the scoop with a vibrating
agitator to work the materials through the siove or colander; and in
providing the body with graduations to indicate the amount of materials
therein.
1

page_text: provided around its outer edge with a flange or lip, which fits up over
the lower edge of the body, and prevents any leakage of the material
from the scoop..
The edges of the bottom and the sides of the body aro provided with
small slits E, through which a wire D is inserted to hold the bottom in
place, the ends of the wire being bent, as shewn in Figure 3, so that
after being inserted it may be locked fast by turning its ends out of line
with the slits.
When the device is to be used as a colander instead of as a scoop I
withdraw the wire and remove the bottom, and insert in place of the
latter a flat colander N, shown in Figure 5. This colander is made of
sheet metal of the same size and form as the bottom M, and is inserted
and fastened by the wire in the same manner.
When the said device is to be used as a sieve or sifter I remove the
bottom or colander and insert in place thereof a sieve C, consisting of a
suitably shaped frame covered with wire, cloth, silk, or such other tissue
or texture as is best adapted for the material to be treated. The sieve
frame is made to fit the bottom of the body in the same manner as the
colander and bottom, but it extends upward, and has its top curved so
that the surface of the sieve is curved in the arc of a circle from the
front side downward to the back of the body or scoop, as shown in
Figure 2. The sieve is locked fast by the wire D, and made removable
in the same manner as the bottom and colander.
It is the intention to provide each scoop with a number of these sieves
and colanders so that by substituting one for another the scoop may bo
adapted for sifting any desired substance or material.
For the purpose of working or forcing the material through the sieves
I mount in the body a skeleton frame or agitator K. arranged to. vibrato
on pivots L closely over the curved surface of the sieve. The agitator
consists in the present case of a series of wires extending transversely
across the scoop with their ends turned up by the sides of the same, and
united to ears or buttons, through which the pivots pass, as shown. In
order that the agitator may be carried closely over the surface of the
siove the curve of the latter is described-from-the-pivots as a centre.
The agitator K is provided with an arm H, which extends up-through a
lip m on the front of the scoop, as shown in Figure 2.- A-thumb pieco
or knob G is applied to the upper end of arm H, and a spiral spring F is

page_text: mounted around the arm, between the thumb piece and the lip, as shown
in Figures 1 and 2.
The scoop is provided on the front side with a handle O, by which to
hold and manipulato it. This handle is so shaped and located that the
operator grasping it can readily place his thumb on the knob or thumb {
piece G, as shown by dotted lines in Figuro 2. The operator dopressing
the said knob causes the agitator K to swing down over the face of the
sieve, and then when he raises or removes his thumb from the knob the
spiral spring raises the agitator with a quick sharp movement. This
movement of the agitator to and fro over the sieve while very casy to 1
the operator feeds the material through the sieve quickly and evenly.
The agitator may be pivoted permanently in the scoop, or it may be
mado removable. In the latter case its pivots may be made with a
head L on one end and a washer and key a at the other, as shown in
Figure 7, so that they can be readily inserted or removed; or the pivots 1
may be secured to the arms of the agitator and arranged to spring
outward into holes in the body.
It is obvious that instead of fastening the bottom sieves or colanders
by the wire any suitable device may be used.
As it is desirable when preparing cake and other compounds to have 2
a convenient means of measuring or weighing the materials I provide
therefor by marking graduations on the side of the scoop body, as shown
at o' in Figure 1, and placing opposite the graduations the numbers or
characters indicating the quantity of material held by the scoop when
the materiel is level with the graduation.
Two or more series of graduations may be provided for different
materials if desired.
It will be seen that the implement constructed as above described
answers all the purposes of a common scoop as well as of a series of
sifters and colanders, and that having the graduations it permits the 3
materials to be measured with ease and accuracy.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,-
First. A scoop 4 provided with a detachable sifter, permitting the use 3
of sifters of different degrees of fineness, as herein set forth.

Second. In combination with the combined scoop and sifter the
agitator K, having the spiral spring applied to its thumb piece.or stem,
substantially as set forth.
Third. In combination with the scoop A containing a scive or sifter
the agitator K made detachable and removable, as herein set forth.
Fourth. In combination with the scoop or body A the detachable
bottom M constructed and arranged for use, substantially as herein
described.
Fifth. The perforated bottom or colander N constructed for use in the.
body A, substantially as herein described.
In witness whereof, I, the said George Haseltine, have hereunto
set my hand and seal, this First day of July, in the year
of our Lord One thousand eight hundred and seventy-four.
