Improvements in Boxes for Brush Making Machines
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention and in what inanuer the same is to be
performed, to be, particularly described and ascertained in and by the following
statement:-
It is customary in making bristle or hair brushes, to hold the perforated brush
back in a box, place the bristles or bau in the box above the brush back, and then
shake or jolt the box up and down until the bristles or hairs are forced into the
perforations of the brush back.
My invention relates to improvements in boxes of this class; and the object of
my invention is to produce a box which can be easily arranged in a shaking or
Jolting machine, which has internal mechanism of a simple character adapted to be
applied to brush backs of different sizes, which has an abutmout plate beneath the
brush back holder, which has a simple moans of adjusting the abutment plate in
relation to the brush back, and which is constructed in such a way as to be very
durable and to work without rattling.
To these ends my invention consists of certain features of construction and
combination of parts, which will be hereinafter described and claimed.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar figures of reference indicate corresponding parts in
all the views

page_text: Figure 12 is a detail sectional view of the fasteuing device as applied to the box
and its shell.
The box 10 has a flaring top portion 11 and a straight or vertical lower
portion 12, the inclination of the top serving to assist in guiding the bristles as
descubed below, and the lower portion being adapted to hold the mechanism for
holding the brush back and gaging the bristles. The box 1 of a generally
elliptical shape to correspond with the usual form of bush back, but obviously
it may be of any necessary shape The box is closed at the bottom, and has a
removable cover 14, which can be fastened in any suitable way, but as the cover
must be attached firmly and yet be quickly applied or removed, the fastening device
shown is desuable.
The fastening devices are applied to opposite sides of the cover, and each has a
stud 15 on the cover, on which is journaled an eccentric 16 having a handle 17
with a laterally proti uding pin 18, which is adapted to engage the shoulders 19 on
diametrically opposite sides of the eccentric strap 20, this strap being mounted
on the eccentric 16 and having secured to it a depending arm 21 with a hook 22
at its free end, to engage a pin 23 on the side of the box
When the handle 17 is swung in one direction, the pin 18 stikes one of the
shoulders 19 and carries the hook 22 into engagement with the pin 23, while the
movement of the eccentric 16 causes the cover to be hugged tightly to the box,
and when the handle 17 13 turned in the opposite direction, the pin 18 strikes the
other shoulder 19 and releases the hook
In the lower portion 12 of the box is a ring 24, which is movable up and down
and has an inner shoulder 25 to support the brush back 26, the shoulder being
placed so that when the brush back is on it the brush back will project slightly
above the ring in order that it may be igidly held as presently described. The
brush back has perforations 27 to let eive the bristles, as shown in Figure 2.
Beneath the ring 24 and extending entirely across the box is an abutment
plate 28 upon which the ends of the bistles stike when the bustles drop through
the perforations in the brush back The distance between the brush back and
abutment plate should be equal to the thickness of the brush back. The reason
for this is that the protruding ends of the bristles are covered with a cement, then
drawn back into the brush back, when the cement fastens them to the brush back,
after which a false or finish back is applied.
The ring 24 and abutment plate 28 are adjusted in relation to each other by
screws 29 which extend vertically through the ing and plate and rest on the floor
of the box, while the heads extend above the ring to the level of the brush back
and against the lining and guide 30, to be more specifically refened to presently.
The lower ends of the screws are of greater pitch than the upper ends, to give the
abutment plate 28 a relatively fast movement, thus enabling it to be quickly
adjusted to different thicknesses of brush hacks, and yet leave the screw heads
level with the blush back
After the brush back is placed in the ing 24 the lining or guide 30 is placed in
the box This guide is thick enough to overlap the edge of the brush back and it
also rests on the screws 29 and extends to the cover 14; consequently when the
cover is locked, the guide 18 clamped firmly in place and prevents the displacement
of the parts below it. Some such arrangement as this is essential to hold the parts
in place, as the box is subjected to violent concussions.
The lining 30 tapers downward and its inner wall 18 vertically corrugated to
prevent the bristles from tipping over when in contact with it. The taper of the
Jining serves to assemble the bristles in a compact mass on the brush back, so that
when the box 15 shaken the bustles readily enter the holes in the brush back. On
the sides of the box are perforated lugs 21 which serve as guides and which are
adapted to run on guide posts on which the box is held when it is shaken.
In Figures 8 to 12 I have shown a slightly modified form of box, which has the
cover integral with the main shell of the box, and is therefore rather stronger than
the box shown in Figures 1 to 7.

page_text: The modified form of box 10" has an outer shell 32 which 18 open at the ends
only, while the inner box comprises the flaring top portion 33, and vertical base
portion 34 and is substantially like the box 10 with its cover removed. The
box 33, 34 has the same internal arrangement as the box 10 (see Figure 10) and it
is slipped end wise into the shell 32 which has the guide lugs 31, so that when the
iunor box is in place the whole device can be readily shaken up and down
Any suitable means may be employed to lock the box to the shell, a convenient
and secure device being illustrated, which has notches 35 in the top edge and
opposite sides of the inner box adapted to engage eccentrics or cains 36 carried by
shafts 37 which are journaled in the outer shell. The eccentrics turn in slots 38 in
the top of the shell 32. The onter ends of the shafts have handles 39 by which
the shafts can be turned and the eccentrics moved into or out of engagement
with the notches 35
When either form of box is to be used, the brush back is adjusted in the ring 24,
the lining and guide 30 inserted above the ring and brush back, the box filled with
bristles placed endwise to the brush back, and the parts held in place by fastening
the cover to the box, in the modified form the top of the shell 32 serving as a
Cover. The box is then jolted up and down, being preferably held on guide posts
extending through the lugs 31, and the bustles drop through the holes in the brush
back with their lower ends resting on the abutment plate 28
By using a series of rings 24 and huings or guides 30, of varying internal
diameters, one box may be used for many sizes of brushes, thus obviating the
necessity of using the customary large number of boxes, and thereby making a
substantial saving in the cost of an outfit for making brushes.
I know that it is not new to form a box with an inclined or tapering top, a brush
back holder, and a bristle gage, and I do not claim such tentures broadly but only
in the combinations herein expressed.
Having now particularly described and ascertained the nature of the said
invention, and in what mabuer the same is to be performed, as communicated
to me by my foreign correspondents, I declare that what I claim is
1. The combination, with the box, of the brush back holding ring, the abutment
plate held below the ring, the removable guide above the ring, and a cover to close
the box top and fasten the parts in place, substantially as described.
2. The combination with the box, of the bush back holding ring, the abutment
plate secured to the rug and held beneath it, a tapering guide above the ring, aud
a cover for the box, substantially as described.
3. The combination with the box, of the brush back holding ring, the abutment
plate adjustably secured to the under side of the holder, the tapering guide to rest
above a brush back and extend to the top edge of the box, and a cover to rest on
the guide and lock the parts in the box, substantially as described
4. The combination of the box having a closed bottom, and a top closure, of the
brush back holding ing, the abutment plate, the adjusting screws extending through
the brush back holding ring and abutment plate and resting on the box bottom,
and the guide between the brush back holding ing and box top, substantially as
described.
