COMPLETE SPECIFICATION.
A New or Improved Rock or Confectionery Chipping Machine.
I, ANDREW RICHMOND, of Aytoun Cottage, Prestwick Road, Ayr, North Britain,
Manufacturing Confectioner, 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 has for its object to provide a simple and efficient machine
for chipping rock.
In order that my invention may be properly understood and readily carried
into effect I have hereunto appended one sheet of drawings of which,
Figure 1 is a front elevation of the machine.
Figure 2 is a side elevation.
Figure 3 is a plan.
In carrying out my invention, I provide a suitable extensible table A, on
which there is fixed in any convenient manner a bar of wood B and to which
bar there are bolted or otherwise connected two uprights C, D, which carry a
lever with an adjustable counterbalance weight F. The upright C is pro-
vided with a slot e in which the lever E works as seen in Figure 2. This lever
is also capable of being adjusted to suit requirements by means of the slot Gin
the upright D and the screw H. Fixed to this lever E there is a cutting or chipping
knife I, and screwed or otherwise fixed to the bar of wood B there is a steel bar J
on which that part of the rock to be chipped rests and which is slightly canted
at front so as to stand a very little above the sliding table to be hereafter
described. Pivoted to the lever E at K there is another lever L-which I will
hereafter call the feeder-which engages with a ratchet M which is fixed to a
travelling table N, having a block or bar of wood 0 forming part of travelling
table N, which presses forward the rock to very end of the stick so that it will
all be cut or chipped. In front of the table A there is a kind of brass comb P
with the teeth p wider than an ordinary comb, the teeth p being flat and slightly
bent as seen more particularly in Figure 2. The rock passes under these teeth
on its way to be chipped, so that the spring on the teeth holds the rock steady
and prevents it from jumping.
P
Suitable stops or buffers u, u are provided at top and bottom of upright C
against which the lever comes.
The operation is as follows:-The sticks of rock are placed side by side on
the table A the ends of the sticks of rock resting on the steel bar J already
described and the lever E is pulled down when the knife I coming in contact
with the rock chips a piece off when it falls on to a table provided for the pur-
pose. As the lever E rises again by means of the counter-balance weight Fit
raises the feeder L with it and in so doing the end of the feeder L engages
with a tooth of the rack M thus draws the travelling table forward, which opera-
tion causes the rock to be pushed forward so that another piece is ready to be
chipped, the same cycle of operations continuing till the whole of the rock has
been chipped or cut.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-

The machine for chipping rock constructed and operating substantially in
the manner herein before described and illustrated on the accompanying sheet
of drawings.
