Improvements in Brush Making Machines.
I, HENRY HARRIS LAKE, of the Firm of [laseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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:-
In making brushes it 18 customary to arrange the bristles or hair in a box
containing a perforated brush back, and then to shake the box violently up and
down so as to force the bristles longitudinally through the perforations in the said
brush back.
The object of the invention is to produce a machine which is of great simplicity,
strong and durable, which is adapted to carry a great many of these boxes, which
hns the boxes mounted on guides between abutment plates which are rigid in
relation to the boxes, so that the boxes meet with a solid abutment at each end of
their movement, thus facilitating the rapid assembling of the bristles, and to
provide a very simple and positive means of rapidly reciprocating the abutment
plates.
To these ends the invention consists of certain features of construction and
combinations 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 and letters of reference indicate corresponding
parts in all the viewa.
Figure 1 is a broken plan view of the machine embodying the invention;
Figure 2 18 a vertical longitudinal section on the line 2-2 of Figure 1 of 'the
machine; and
Figure 3 is a cross section on the line 3-3 of Figure 1.
In connection with the shaking machine, boxes 10 are used which will not be
described in detail, as they form no part of the invention but which are adapted to
contain the bristles and brush backs to be shaken. The present invention relates
wholly to the means of shaking these boxes.and therefore it is needless to show the
construction of the boxes.
"
The boxes 10 are held between abutment plates 11 and 12 which are rigid in
relation to the boxes and which are longitudinally slotted, as shown at 13, to
render them lighter and also to prevent them from offering too great resistance to
the air when they are vertically reciprocated. The boxes 10 are provided with
side guides 14 which run on plus 15, these being secured to the lower plate 11, and
the pins, besides serving to guide the boxes and prevent their displacement, also
hold the plates 11 and 12 the necessary distance apart, as the plate 12 rests on the
tops of the pins 15. It will of course be understood that other means may be

page_text: employed for preventing the displacement of the boxes, that is, for preventing them
from slipping out from between the abutment plates 11 and 12, without affecting
the pinciple of the invention. The plates 11 and 12 are mounted to slide
vertically on posts 16 which are secured to a suitable frame 17 and the plates are
locked together by any suitable fastening devices, the devices shown each consisting
of a lk 10 pivoted to the lower plate, a lotch 16 on the upper end of the link,
and a catch 16 on the upper plate 12 to engage the latch 16.
The lower plate 11 rides on the long teeth 18 of oppositely arranged cog
wheels 19 which are mounted on shafts 20, these being journaled transversely on
the frame 17, and the cog wheels are made long in order that the teeth may have a
good bearing on the under side of the plate 11. The cog wheels are oppositely
revolved when the machine is in,motion, and it will be seen that the lower plate 11
will be dropped successively from tooth to tooth, that the upper plate 12 will
move in unison with the lower plate, and that the constant jolting of the two
plates will cause the boxes 10 to be rapidly reciprocated up and down on the guide
pins 15.
One of the shafts 20 is provided with a driving pulley 21, and both shafts have
pulloys 22 which are connected by a cross belt 23 in order that the shafts and cog
wheels may be oppositely rotated, but this contrivance for driving the shafts is
shown merely to illustrate an operative machine, and it will be understood that
any suitable means may be employed for giving the desired rotation to the cog
wheels.
When the machine is to be used, the top plate 12 is removed and the boxes 10,
which have been filled with bristles and are to be shaken, are placed on the guide
pins 15, after which the top plate 12 18 fastened in place and the machine set in
motion. The abutment plates 11 and 12 are rapidly reciprocated by coming in
contact with the successive teeth of the cog wheels and the rapid up and down
movement of the plates causes a similar jolung movement to be imparted to the
boxes, which, however, move up and down independently of the plates by reason
of the sudden jolts which they receive, and thus the boxes are very efficiently
shaben.
It is not new to provide a jolting platform to shake brush boxes of the kind
described, and such features are not claimed broadly, but only in the combinations
herein expressed.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I clum 18 :-
1. The combination, of the reciprocating abutment plates, the boxes held loosely
between rhe plates, and means for preventing the displacement of the boxes,
substantially as described.
2. The combination, of the reciprocating abutment plates, movable in relation to
each other, a fastening device to hold the plates together, the boxes held between
the plates, and means for preventing the displacement of the boxes, substantially as
described.
3. The combination, of the oppositely arranged reciprocating abutment plates,
the boxes held loosely between them, the guides for the boxes, and guide posts
carrying abutment plates, substantially as described.
4. The combination, of the oppositely arranged abutment plates, having openings
there to prevent excessive resistance to air, the guides between the plates, and
the boxes held loosely on the guides, substantially as described.
5. The combination, of the oppositely arranged reciprocating abutment plates, a
fastening device to hold the plates together, guides arranged between the plates
and limiting the distance between them, and boxes held to slide on the guides,
substantially as described.
6. A machino of the kind descubed, comprising guide posts, oppositely arranged

page_text: abutment plates to slide on the posts, moans for holding boxes between the
abutment plates, and cog wheels having their teeth supporting the lower abutment
plate, substantially as described.
