the scatterers or sieves. It is obvious that
these sieves may be constructed of a fixed
length; but I prefer to construct them so that
they will telescope. A suitable construction
5 to that end is to form the sieves in cross-sec-
tions, so that one set of strips, r, will lap onto
the other set, as shown in Figs. 2 and 5, and
be provided with set-screws or bolts t, enter-
ing slots a in the other set of strips, so that
Io one set of strips may be guided and adjusted
along the other set, thus enabling the two sec-
tions to telescope to make the sieve longer or
shorten:, as may be desired. These sieves are
preferably octagonal in cross-section, and the
15 longitudinal strips r are extended within the
sieves the distance of about one inch to form
floats or dashers to agitate the material within
the sieves, as will be readily understood and
seen from reference to Figs. 2 and 5. Each
20 sieve is provided with a sliding door, e, work-
ing in guides thereon and provided with a
suitable knob or handle, by which it may be
readily moved when necessary. These sieves
are made adjustable on their shaft C, and this
25 may be accomplished in various ways, al-
though I prefer that shown, which consists in
providing the spindle C' with an angular
shoulder, f, fitting in an angular hole made
in one head of the sieve, so that the sieve and
30 spindle will turn together. This spindle will
fit into the shaft C, made tubular for the pur-
pose, so as to allow the sieve to adjust in or
out. To the inner head of the sieve is con-
nected a collar, g, through which a set-screw,
35 h, passes and bears against the shaft C, so as
to secure the parts together, in order that
they may all turn together.
When it is desired to adjust the sieve closer
together or farther apart to suit rows of plants
40 of greater or less distance apart, it is only
necessary to loosen the set-screws h and slide
the sieves along their shaft to the desired
point, and then by tightening the set-screws
the sieves will be firmly held in their adjusted
45 position.
In order to prevent waste of the powder
used, and at the same time to protect the eyes
of the person using the device, as well as the
horse, I provide a shield, K, which may be
50 varied to some extent in its shape, but the
preferred form of which is shown in Figs. 1
and i, in which the shield is pivoted to the
shaft C in order to provide for the turning up
of the said shield when desired to replenish
55 the sieves. Each shield may be secured by
having one end apertured so as to slip over
the shaft C, while the other end is apertured
and held up by a bolt or journal-pin, i, passed
through the aperture and into a block or
60 spool, I, provided at the end of spindle C'.
The shields are thus free to be turned on the
shaft and spindle when desired, but do not
revolve with the shaft and sieves. They are
open at their bottoms and are provided with
65 pivoted doors J, having a recess, I, to pass
around the shaft C, and when closed fit into
guides or clasps 1. They may, if desired, beprovided with depending curtains or aprons
of some fabric material, as indicated by dotted
lines in Fig. 1. 70
The shields may be omitted without de-
parting from the essence of the invention or
detracting from the usefulness of the remain-
ing parts.
L are brace or supporting rods fitting in 75
sockets m on the sides of the shields and at
the other ends removably secured to the frame
A, preferably in the manner shown-that is,
the plate i, secured to the said frame, has a
notch, o, in it, to the rear of which, in the side 80
of the frame, is a recess, p, into which the ex-
tended end of the brace-rod fits, the said end
being notched, as shown, at v, and engaging
the said plate, being thus made secure, yet
easily removable. These rods form the sup- 85
port for the shield.
The frame constructed as described is
easily applied to saddles of varying sizes and
will fit closely to them, while at the same time
it can be quickly applied and removed. Itis 90
also simple in construction, inexpensive to
manufacture, and strong and durable in use.
Having described my invention and set
forth its merits, what I claim is-
1. The combination, with a powder-duster, 95
of its supporting - frame provided with the
stop-block F, applied to the frame between
its sides to bear against the horn of a saddle,
and suitable means for securing it to the sad-
dle, substantially as and for the purposes set oo
forth.
2. The combination, with a powder-duster,
of its supporting-frame provided with a stop-
block applied to fit the horn of a saddle, and
the collar G, secured to said frame and curved 105
to rest upon the crown of the saddle, and
means for securing the frame to the saddle,
substantially as and for the purposes set forth.
3. The frame carrying the sieves and pro-
vided with the stop-block having a concave I o
face to fit the curve of the horn of a saddle,
and the cross-pieces above said stop -block
having concave portions, said blocks form-
ing a space to receive the pommel of a sad-
dle, substantially as and for the purposes set 115
forth.
4. The combination, with the frame formed
with a recess to receive the horn of a saddle
and provided with a strap for securing it to
said horn, of the rotary shaft and the sieves 120
adjustably secured to said shaft to be shifted
lengthwise thereon, substantially as and for
the purposes specified.
5. The combination, with the frame and
the main tubular shaft journaled therein, of 125
the spindle fitting in said tubular shaft, and
the rotary sieves secured to said spindle and
adjustable lengthwise on said shaft and pro-
vided with fastenings for holding them in
their adjusted positions, substantially as de- 130
scribed.
6. The combination, with the shaft and a
support therefor, of the sieves secured to said
shaft and formed in sections to telescope
