Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVEMENTS IN MACHINERY FOR GRINDING AND
POLISHING THE SURFACES OF STONE AND METAL." -A communication
from abroad by John Henry Volk, of Chicago, Illinois, United
States of America.
Sealed the 2nd April 1875, and dated the 4th November 1874.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 4th November 1874.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR GRINDING
AND POLISHING THE SURFACES OF STONE AND METAL," a communication, to be
A-11

page_text: To produce a fine polish I use for finishing a cylinder lined with
wood or other suitable material faced with polishing cloth or other
polishing material.
Sharp sand, coarse sand, fine sand, and then finer material may be
introduced into the rubbing cylinder while revolving, and water is
applied in any suitable manner. For this purpose I prefer to use a
small perforated pipe nearly parallel with the column, passing through
the cylinder. To keep the sand and water away from the driving belt
the said cylinder may be bevelled on the inside at each end, so that the
sand and water will be thrown off at an angle and away from the said
belt.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 4th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of November, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Robert Lako, Her
special licence that I, the said William Robert Lake, my executors,
administrators, and assigns, or such others as I, the said William
Robert Lake, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN MACHINERY FOR GRINDING AND POLISHING THE
SURFACES OF STONE AND METAL," a communication to me from abroad by
John Henry Volk, of Chicago, Illinois, United States of America, upon
the condition (amongst others) that I, the said William Robert Lake, my
exccutors or administrators, by an instrument in writing under my, or
their, or one of their lands and seals, should particularly describe and

which may also be adjustable ; D is the polishing cylinder; a, a, are its
flanges; E is a belt; F, a driving pulley or shaft. In Figure 3 6 is
wood; c is polishing cloth; in Figure 5 d is the outer casing or cylinder;
c, the inner lining or cylinder; f, f, are keys to hold them together;
9, 9, are rods or shafts on which are guide pulleys h; they are adjustable,
and can be moved on the rods by one or more screws r, or otherwise.
.
The polishing cylinder can be moved from end to end of the column
by hand, for example, by pressure on the edge of the belt, or
automatically by the use of any suitable devices used for similar.
purposes.
-
- In many cases two or more cylinders can be used at the same
time.
The column or other article over which the cylinder is to be moved
must be placed parallel with the driving pulley whose shape must be
adapted to the work; where the column swells the pulley must be cut.
away..
It will be obvious that taper objects and those having swells or enlarge-.
ments can be polished by this Invention.
"
•
In polishing ornamental objects, such as the base of an architectural
column a number of separate rings must be used, each shaped on the
inside to fit the parts to be polished by it..
.
It is intended to rotate the work in one direction and the aforesaid
cylinder ring or sleeve, in the opposite direction. But in the polishing
of an oval column the latter remains stationary, the cylinder only
revolving. Such columns and other peculiar ornamental objects will
require to be finished by hand at some points.
.
The polishing.cylinder encircles the work. A small cylinder will not
require guides; but it will be desirable to have guides for large cylinders.
For this purpose I use guide rollers having flanges to come in contact
with flanges on the cylinder, and placed on rods parallel with the machine
or column, the said rods being suitably supported at the ends, as in
Figure 5, which shows these guide rollers made adjustable.
To produce a fine polish I use for polishing a cylinder lined with
wood or other suitable material faced with polishing cloth or other
polishing material as in Figure 3.

page_text: Sharp sand, coarse sand, fine sand, and then finer material may be
introduced into the rubbing cylinder while it revolves, and water is
applied in any suitable manner. For this purpose I prefer to use a
small perforated pipe nearly parallel with the column and passing
through the cylinder to keep the sand and water away from the driving 5
belt.
The said cylinder can be made of any desired length and may be
bevelled on the inside at each end, so that the sand and water will be
thrown off at an angle and away from the belt.
Having thus fully described the said Invention as communicated to 1
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,—
First. In a machine for polishing columns and the like, a polishing
cylinder sleeve or ring constructed and arranged to encircle the column
or other object and operated as herein set forth.
Second. The combination of the frame, polishing cylinder, and driving
pulley or shaft, as herein set forth and for the purposes specified.
Third. The guide rollers in combination with the said polishing
cylinder, as herein set forth and for the purpose specified.

Fourth. A polishing cylinder consisting of an exterior casing fitted 2
with the removable interior lining, as hercin set forth and for the purpose
specified.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Third day of May, in the
year of our Lord One thousand eight hundred and seventy- 2
