A New or Improved Apparatus for Holding and Delivering Powder
and similar Substances.
I, JACOB CALVIN MICHAEL, of 381 Eighth Avenue, in the City, County and
State of New York, United States of America, Chemist, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of this invention is to provide a receptacle for holding all kinds of
powders, of which small quantities are desired to be used from time to time, and
from which the powder may be delivered easily and without trouble in such
quantities as is desired; and although useful for many other purposes, the same is
designed and more particularly intended for holding tooth powders, and delivering
the same upon the brush in suitable quantities for use.
This invention consists broadly, of a suitable supported box or receptacle provided
at its lower end with a tube, open at the bottom, which projects into the interior
thereof, within which tube is a second tube of slightly smaller diameter adapted to
move easily in the first tube, also open at the bottom, and provided with openings
in its sides adapted to register with similar openings in the sides of the first tube, in
communication with the interior of the receptacle, when the inner tube is moved by
pressure from beneath; and also further consists in providing a suitable stand of
peculiar construction, to be used in supporting such powder receptacle, from which
one receptacle when empty may be removed, and a full one substituted therefor.
Said invention is fully disclosed in the following Specification, of which the
accompanying drawings form a part, wherein similar numerals of reference designate
like or equivalent parts wherever found throughout the several views, and in
which-
Figure 1 designates a side view of my improved powder holding and delivering
receptacle in position in my improved support therefor; Figure 2, a rear view of the
same; Figure 3, a view in central longitudinal section of the lower portion of such
receptacle, showing the construction of the delivering mechanism; and Figures 4
and 5, views in detail of modified forms of certain portions of the delivering
mechanism shown in Figure 3.
Referring to the drawings, the numeral 1 designates a box or receptacle of any
suitable material, preferably of thin sheet metal, and of any desired shape, but
preferably substantially cylindrical, as shown. This box or receptacle, 1, is closed
at the upper end by a suitable top piece, preferably secured firmly thereto in any
convenient manner, and at the other end is closed by a bottom 2, which is preferably
of substantially the inverted dome shape shown. The box 1 and the bottom 2 are
each preferably provided with corresponding beads 3 and 4, which fit into one
another when the bottom is forced upon the box, in such manner as to hold such
box and bottom firmly together, and prevent the same from being taken apart,
except by the use of great force or appropriate tools.
Firmly secured in a hole formed in the centre of the dome shaped bottom 2,
preferably by being made slightly larger than the hole, and sprung into place
therein in the manner common in the manufacture of thin sheet metal goods, is a
tube 5, preferably formed of the same thin sheet metal as the box 1 and bottom 2.
This tube 5 projects into the interior of the box 1, for a short distance, preferably
to about the depth of the dome shaped bottom 2, as shown; and the same is open
at the outer end, and preferably closed at its inner end by a cover 6, formed
integral therewith, or secured firmly thereto in any desired manner. In order to

page_text: hold the tube 5 firmly in place in the bottom 2, and prevent wobbling of the same,-
the central hole of such bottom 2, when first formed therein, is preferably made
much smaller than the tube 5, and is then enlarged by forcing outward the surplus
metal so as to form a flange 7, surrounding the hole, until the same is of sufficient
size to allow the tube to be forced into position therein.
Formed in the side walls of the tube 5, just within the dome of the bottom 2, and
extending upward along the tube from the inner side of the bottom to about
one-third of the height of such tube, are one or more holes or openings 8, preferably
of substantially rectangular shape as shown; and sliding easily up and down in
said tube 5, is an inner tube 9, of such size as to fit snugly within, and still be
capable of movement. This tube 9 is open at the outer end, and also preferably at
the inner end as well, and is provided with holes or openings 10, formed in the side
walls thereof, of substantially the same shape, size and number as the openings 8 in
the tube 5, which openings 10 are adapted to register with the openings 8 only when
the tube 9 is raised above its normal position by being pushed back into the tube 5
as far as it will go; the openings 8 being normally closed by the upper portion of
the side walls of the tube 9, as shown in Figure 3. The tube 9 is of substantially
the same length as the tube 5, and is held in place therein, and prevented from
falling completely out of such tube 5, when the device is in position with the
bottom 2 downward, by any convenient means, preferably by wires 11, which pass
through holes formed in such tube 9, just above the openings 10, and also through
the openings 8 in the tube 5. These wires 11 are preferably curved upward, and
extend nearly to the circumference of the bottom 2, with the interior of the dome
of which they are nearly in contact throughout their entire length, as shown, and
the same act as agitators to throw down the powder to the openings 8, when the
device is operated, as will be more fully explained hereafter
Within the tube 9, and resting either on a metallic button 12, supported by
the wires 11, or on such wires themselves, is preferably placed a spiral spring 13, the
upper end of which bears against the end 6 of the tube 5, in such manner that the
tube 9 is kept normally forced out of the tube 5, as far as the wires 11 will allow
the same to go, whereby the openings 8 are normally kept closed by the upper
portion of the walls of the tube 9, as hereinbefore stated.
The frame or support 14, in which the receptacle or box I is held in position to
be operated with the domed bottom 2 downward, as shown in Figures 1 and 2, may
be constructed of any desired material, and of any preferred form, but I prefer the
one shown, wherein such frame or support is made of tinned wire twisted into the
required shape.
In this form, such support consists of a bottom portion or base 15, provided with
short legs 16, on which the device rests, and supporting a shallow removable dish 17,
adapted to receive any of the waste powder which may accidentally fall from the
tube 9. Supported by the base 15, and extending upward from one side of the same,
is a standard 18, of any desired form of construction, preferably of that shown, to
which are secured at appropriate points, rings or clasps 19, adapted to encircle the
box or receptacle 1, and hold the same firmly in position when the same has been
placed therein. These rings or clasps 19 are preferably of the form shown, the two
ends thereof being attached to different wires of the standard 17 so as to spring
slightly apart to allow the box to be forced into the rings and then to close together
again so as to grip the same tightly.
The operation of the device is as follows:-
The box or receptacle 1 having been filled with the required kind of powder, and
the bottom 2 having been forced upon the same until the beads 3 and 4 slip into one
another, the same is next forced down into the rings or claps 19, of the support 14,
the dome shaped bottom 2 being downward, until such box 1 is in the position
shown in Figures 1 and 2, when the device will be ready for use.
When it is desired to obtain powder from the receptacle it is only necessary to
lift
up the sliding tube 9, by pressing upward against the lower end of the same
with the tooth brush, cloth, or whatever other article is used for applying the

page_text: powder, and as soon as such tube 9 is lifted up sufficiently far for the openings 10 to
register with the openings 8, powder will fall through such openings 8 and 10 into
the tube 9, and out of the end thereof, upon the brush, rag or other implement used.
If sufficient powder is not obtained at one movement, it may be lifted again and
again until the desired quantity is obtained. Ordinarily but one movement of the
tube 9, is necessary, as the wires 11, rising through the powder, serve to shake the
same down toward the openings in the tube 5; but should the powder become
caked high up in the box out of reach of the wires 11, it can easily be shaken down
by tapping lightly two or three times upon the upper end or the sides of the box or
receptacle 1.
In order to compel the openings 8 and 10 to register accurately with one another
when the tube 9 is raised, if desired, one or more of the openings 8 may be
provided, as shown in Figure 4, with a central slot 20, at the top thereof, the side
lines of which merge by a gentle curve into the side lines of the opening 8, so that
on the tube 9 being raised the wires 11 will be directed into such slot 20, and the
openings 8 and 10, will thus be registered unerringly and accurately.
If desired, in order to give greater range of movement to the shaking wires or
agitators 11, one of the openings 8, in the tube 5, may be omitted and a spiral
slot 21 formed in place thereof, as shown in Figure 5. Through such slot 21
passes one of the wires 11, which is of such size as to slide easily along such slot,
and consequently when the tube 9 is raised or lowered a rotary movement is given
to the tube 9, and to the wires 11, whereby such wires are brought into contact
with the powder throughout the entire circumference of the box, and are caused
to shake the powder down to the point of the dome shaped cover next to the
openings 8.
When all of the powder in the box or receptacle 1 has been taken therefrom in
the manner described, the same may be removed from the support 14, by slipping
the same out of the rings or clasps 19, and another full receptacle may then be
substituted therefor; or if desired, the bottom 2 may be taken off, the box filled,
the bottom replaced, and the same receptacle may be replaced in the rings or
clasps 19; and this operation may be repeated indefinitely.
Although I prefer to use a spring as 13, for keeping the sliding inner tube 9
normally forced out of the tube 5, for the reason that the openings 8 are thus kept
closed even when the box 1 is placed with the dome shaped bottom upright, as is
frequently the case in shipping such boxes, it is evident that a weight may be
substituted for such spring 13, or that in some cases both spring and weight may be
omitted, and the tube 9 and wires 11 be made of sufficient weight to fall by gravity
into the position shown in Figure 3 whenever the receptacle or box 1 is placed with
the bottom 2 downward.
It is evident that this improved receptacle may be used without the support 14
by being held in one hand during the operation of delivering the powder therefrom,
and that the same may be used for holding and delivering powders of all kinds ;
and I do not limit myself to the use of the same with the support, or for holding and
delivering any particular kind of powder; neither do T limit myself to any
particular form of construction, combination or arrangement of the various parts of
my improved powder holding and delivering device, as it is evident that many
changes and modifications in the construction thereof, other than those named
herein, may be used without departing from the scope of my invention.
