Improvements in and relating to Tooth Brushes and Casings therefor.
I, DANIEL WEBSTER TOWER, of Grand Rapids, in the State of Michigan, United
States of America, do hereby declare the nature of this invention to be as
follows:-
This invention relates to tooth brushes and casings therefor. The object of the
invention is to provide a casing especially useful for fountain tooth brushes having a
collapsible tube for containing the dentifrice, which may be quickly and easily
applied and removed, and when applied to the brush will permit evaporation. of
the dentifrice, and thereby prevent the brush fibres from being gummed or stuck
together, and in which, furthermore, the part of the casing inclosing the brush
proper is independent of the part enclosing the stem or tube, whereby the latter
may be replaced after the brush fibres have been supplied with dentifrice to protect
the collapsible tube and serve as a handle for the device.
A brush attached to a suitable back and provided with a central flexible, nipple
to discharge the paste has bath ends shaped alike. A hollow stem, which may
or may not have a stop cock near the middle to stop the flow of paste is provided
with a flange at one end, having downwardly and inwardly turned edges to engage
the sides and inner end of the brush back and secure the same to the stem. The
downwardly and inwardly-turned edges of the flange are at the side and rear end
only thereof, whereby the front will be left open to permit the brush-head to be
introduced longitudinally through the same, as the brush head is of the same
construction at both of its ends. It will thus be seen that the brush head may be
removed and replaced in reversed position end for end, thus greatly prolonging
the life of the fibres. The stem is also provided with a screw socket to engage
the screw-threaded end of a collapsible tube, which tube contains the supply of
dentifrice or paste, and said stem, is also provided with a sleeve outside, said
screw-threaded socket to engage the open end of a handle case and detachably
secure the same in place, outside of and inclosing the tube. Said case and sleeve
are preferably oval in cross section to accommodate the collapsible outer end of
said tube. A casing enclosing the brush is divided longitudinally and provided
with a hinge and catch at its respective sides and when closed is connected to the
handle case by overlapping the end of the same. This casing is also formed with
a number of perforations to permit evaporation of the dentifrice from the fibres,
and thereby prevent gumming the latter.

I, DANIEL WEBSTER TOWER, of Grand Rapids, in the State of Michigan, United
States of America, 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::.
This invention relates to tooth brushes, and casings therefor, and consists
in the novel features hereinafter described and claimed. The object of the
invention is to provide a casing especially useful for fountain tooth brushes having a
collapsible tube for containing the dentifrice, which may be quickly and easily
applied and removed, and when applied to the brush will permit evaporation of
the dentifrice, and thereby prevent the brush fibres from being gummed or stuck-
together, and in which, furthermore, the part of the casing inclosing the brush
proper is independent of the part enclosing the stem or tube, whereby the latter
may be replaced after the brush fibres have been supplied with dentifrice to protect
the collapsible tube and serve as a handle for the device.
This object is accomplished by the construction illustrated in the accompanying
drawing, in which
Fig. 1 is a central longitudinal section of a device embodying my invention.
Fig. 2 is a back view of the same with the brush case removed.
Fig. is a side view of the device entire; and
Fig. 4 the same with the entire case removed, and showing a stop valve in the
stem..
A is the brush proper, attached to a suitable back A¹ and provided with a
central flexible nipple B, to discharge the paste and having each of its ends of
the same form,; C is a hollow stem, which may or may not have a stop cock K,
near the middle to stop the flow of paste and is provided with a flange Ci
at one end, having downwardly and inwardly turited edges to engage the sides
and inner end of the brush back A¹ and secure the same to the stem C. The
downwardly and inwardly-turned edges of flange C are at the side and rear end
only thereof, whereby the front will be left open to permit the brush-head
to be introduced longitudinally through the same, and the brush head
is of the same construction at both of its ends. It will thus be seen
that the brush head may be removed and replaced in reversed position end
for, end, thus greatly prolonging the life of the fibres. The stem C is also pro-
vided with a screw socket D to engage the screw-threaded end of a collapsible
tube F, which tube contains the supply of dentifrice or paste, and said stem is' also
provided with a sleeve E outside said screw-threaded socket to engage the open
end of a handle case G and detachably secure the same in place, outside of and
enclosing the tube F. Said case and sleeve are preferably oval in cross section
to accommodate the collapsed outer end of said tube. His a case to inclose the
brush Said case is divided longitudinally and provided with a hinge. I and
catel J at its respective sides and when closed is connected to the handle case G, by
overlapping. the end of the same; being provided with a circumferential groove M
engaged by a corresponding head L in said handle case. Case H is also formed
with a number of perforations to permit evaporation of the dentifrice from the
fibres, and thereby prevent gumming of the latter.
In the operation of the device, the cases G and Hcare, removed and a portion of
the contents of the tube-F forced through the stem and nipple B and into the
brush As the cases G and H are formed of separate sections, the former may
now he replaced so as to provide a rigid handle to be grasped by the user, and
thereby protect the collapsible tube and prevent the waste of dentifrice that

page_text: might occur if said collapsible tube were used as the handle. The stop cock K
is then closed to prevent further flow of the paste. The stop cock K may be
omitted as in Fig. 1, and the device will operate, especially if the tube F is made
somewhat heavier than usual. The socket D and end of the tube F may also be
plain instead of screw-threaded.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed. I declare that what 1
claim is:-
-
1. A casing for tooth brushes, consisting of a part to inclose the stem and a
separate part to inclose the brush proper, said latter part being formed of hinged
sections, whereby the brush proper may be uncovered without uncovering the
stem, as specified.
2. A casing for tooth brushes, consisting of a part to enclose the stem and a
separate part to enclose the brush proper, said latter part being constructed of hinged
sections having perforations.
3. In a tooth brush, the combination with the tubular stem having a brush at
one end, and a collapsible tube attached to the other end of said stem, of a sleeve
encircling the latter end of the stem, and a casing enclosing said tube and detach-
ably secured to said sleeve, substantially as described.
4. The combination with a fountain tooth brush, having a tube to contain the
dentifrice and provided with a sleeve, of a detachable casing for said tube, engaging
said sleeve and provided with a bead, and a detachable casing for the brush proper,
said latter casing having a groove to receive said bead and being formed of
sections hinged together at one side and provided with a catch at the other side of
the casing..
