PROVISIONAL SPECIFICATION.
Improvements in or connected with Brush Making Machines.
I, ANDREW HOUSTON MORIER of 145 Argyle Street, Glasgow, Brush
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention consists of an arrangement by which the brush stock is auto-
matically clutched in the working of the roaching machine. A lever is attached
at one end to one of the two claws between which the brush stock is to be held.
The other end of the lever has a spiral spring attached, which tends to draw the
claws together. This tendency is resisted by a leather or other flexible band, when
the slide on which the brush stock is placed is drawn away from the cutting tool.
When a brush stock is placed in position and the slide brought up towards the
cutting tool, the leather or other flexible band is loosened and the spiral spring
is allowed to act on the lever so as to bring the claws together and clutch the brush
stock firmly between them.

COMPLETE SPECIFICATION.
Improvements in or connected with Brush Making Machines.
I, ANDREW HOUSTOUN MORIER of 145 Argyle Street, Glasgow, North Britain,
Brush Manufacturer, 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 consists of an arrangement by which the brush stock is auto-
matically clutched in the working of the roaching machine. A lever is attached at
one end to one of the two claws between which the brush stock is to be held.
The other end of the lever has a spiral spring attached, which tends to draw
the claws together. This tendency is resisted by a leather or other flexible band,
when the slide on which the brush-stock is placed is drawn away from the cutting
tool.
When a brush-stock is placed in position and the slide brought up towards the
cutting tool the leather or otlier flexible band is loosened and the spiral spring is
allowed to act on the lever so as to bring the claws together and clutch the brush-
stock firmly between them.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended two explanatory sheets of drawings.
The roaching machine is a machine for shaping the stocks of brushes, and
this invention is for an automatic clutch by which the stock is firmly gripped while
being moved up on the slide to the tool for forming the block into shape.
In the drawing, A A is the slide, and B. Care two claws forming the clutch.
One of the claws B is fixed to the slide, while the other. C', is moveable between
two guides D D attached to the slide. The block C is connected to one end e of
a lever E by means of the link F. The lever is pivoted at e'. A leather
band G fixed at one end to a stationary part of the machine is attached to the
end of the lever. A spiral spring H pulls the lever in the opposite direction to
the leather band. The spiral spring is fixed at one end to a hook h on a bar I, which
is fixed to, and moves with, the slide A.
In Figure 1 the slide is shown drawn away from the cutting tool. In this case
the leather band has prevented the end of the lever from going back with the

slide as it was removed from the tool. The consequence of this is that the end of
the lever travels back relatively to the slide, and draws the elaw with it. The
piral spring is also extended. When the slide is pushed in towards the tool, as
shown in Figure 2, the spiral spring takes up the slack of the leather band.
and all the end of the lever back, which pushes the other end with
link and jaw (forward relatively to the slide. The distance between the
two jaws is thus diminished, and the brush-stack firmly gripped.
Having now particularly described and ascertained the unture of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is
In coaching nechines, an automatic arrangement for elutehing the brush-block
which operates as the slide holding the block is pushed forward to the cutting
tool, substantially as described.
