"
& Co., Patent Agents, Southampton Buildings, London, for the Invention of
IMPROVED APPARATUS FOR THE CONVERSION OF HIDES INTO LEATHER."
A communication from abroad by Charles Louis Royer, of San Francisco,
California, United States of America.
Sealed the 26th May 1876, and dated the 6th March 1876.
PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 6th March 1876.
"
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVED APPARATUS FOR THE CONVERSION
OF HIDES INTO LEATHER." A communication.
My Invention has for its object the conversion of hides into leather to be used
for belting, lacings, and other articles, wherein it, is necessary to preserve the
native strength and toughness without destroying or impairing the natural fibres
or grain of the leather.
The said Invention comprises a vertical slotted rotating shaft, around which the
hide will be tightly wound and then treated in order to be converted into leather.
It also comprises a weight or press for compressing downward the coil of hide on
the said rotary shaft. Also a cage that may be readily opened, so that access will
be had to the hide, and a clamp for holding the end of the hide in the slot of the
said rotary shaft. Power is imparted to the said rotary shaft in any suitable or
well known manner. The said weight is fitted on the shaft, and it will act in
compressing downward the coil of hide on said shaft.
The aforesaid cage, which consists of open or slatted work, and is formed in
sections, the frames of which are hinged to each other, so that the said sections
may be made to open from and close around the rotary shaft. The sections of
this cage will be closed and the hide rolled on the shaft, the cage then preventing
expansion of the roll.
If for any purpose it is required to reach the coil or shaft the sections of the
When the
cage are opened, and the coil and shaft are immediately accessible.
cage is closed a bolt, latch, or other fastening will be employed to secure the
sections.

page_text: The aforesaid clamp for the hide consists of a disc with a studded brace, and it
is fitted in the vertical slot of the shaft, in which slot the end of the hide will be
inserted. By tightening the set screws the clamp will be firmly pressed against
the hide, and the latter securely held.
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 5th
September 1876.

My Invention has for its object the conversion of hides into leather to be used
for belting, lacings, and other articles wherein it is necessary to preserve the native
strength and toughness without destroying or impairing the natural fibres or grain
of the leather.
The said Invention comprises a vertical slotted rotating shaft, around which the
hide will be tightly wound and then treated in order to be converted into leather.
It also comprises a weight or press for compressing downward the coil of hide on
the said rotary shaft. Also a cage that may be readily opened, so that access can
be had to the hide and a clamp for holding the end of the hide in the slot of the
said rotary shaft.
Figure 1 is a top view or plan, partly in section, of the said apparatus; Figure 2
is a vertical section thereof on the line x, x, Figure 1; Figure 3 is a section of a
clamp forming part of the said apparatus detached.
Siinilar letters of reference indicate corresponding parts throughout the
Drawing.
A represents a rotary shaft, to which power is imparted in any suitable or well
known manner, and on which the hide is to be wound to be treated and converted
into leather; A represents a weight which is fitted on the shaft A for compressing
downward the coil of hide on said shaft; B represents a cage which consists of
open or slatted work, and is formed in sections B', B', whose frames are hinged to
each other, so that the sections may be made to open from and close around the
rotary shaft. The sections of the cage will be closed and the hide rolled on the
shaft A, the cage then preventing expansion of the roll.
If for any purpose it is required to reach the coil or shaft the sections of the
cage are opened, and the coil and shaft are immediately accessible. When the
cage is closed a bolt, latch, or other fastening will be employed to secure the
sections; C represents the aforesaid clamp for the hide, consisting of a disc with
a studded brace, and it is fitted in the vertical slot of the shaft A, in which slot
the end of the hide will be inserted. By tightening the set screws a the clamp
will be firmly pressed against the hide and the latter securely held.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
First. An apparatus for treating hides having a rotary shaft A arranged and
operating as above described, and for the purpose set forth.
Second. The weight or press A¹ operating in combination with the shaft A, as
above described and for the purpose set forth.
Third. The cage B, formed of opening and closing sections, as above described and
for the purpose set forth.

page_text: Fourth. The studded clamp C operating in combination with the shaft A, as
above described and for the purpose set forth.
Fifth. The apparatus for treating hides, consisting of the parts shewn in the
accompanying Drawing, constructed, combined, and operating, as above set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Fifth day of September, in the year of our Lord One
thousand eight hundred and seventy-six.
