Year: 1874

page_text: LETTERS PATENT to Henry Malcolmson, of 5, Southampton Buildings,
Holborn, in the County of Middlesex, for the Invention of "IM-
BOOK AD PALLED SANDS"
PROVISIONAL SPECIFICATION left by the said Henry Malcolmson at
the Office of the Commissioners of Patents, with his Petition, on
the 7th May 1874.
I, HENRY MALCOLMSON, of 5, Southampton Buildings, Holborn, in
the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN DRAWING-ROOM OR ROLLER SKATES," to be as
follows:-
This Invention consists in constructing drawing-room or roller skates
in such a manner that curves and other evolutions may be performed
with more ease than heretofore by constructing them with three rollers
disposed as hereafter described and adapting steel springs to skates con-
structed with two or more rollers. The illustrative Sheet of Drawing
which accompanies this description shows the manner by which I
propose to obtain the above object,

page_text: Figure 1 is a plan; Figure 2, an elevation of a drawing-room or roller
skate constructed according to my said Invention. In each of these
views similar letters are used to denote corresponding parts.
A is the skate stock; B, B¹, two brackets fixed thereto; C is a frame
which serves to hold the axle D of the front roller E. This frame is
provided with a spigot F, which passes through a circular hole in the
bracket B. This spigot is split at f. C¹ is another frame for the axle of
the two rollers E¹, E", kept asunder by means of the collars e, e¹, and
arm c. This frame is also provided with a spigot F', which passes through.
a circular hole in the bracket B'. This spigot is also split in f¹. The
spigots F, F¹, are united by means of a flat steel spring G, which fits
into the split parts f, f', and is held therein by means of pins or rivets g.
This flat spring is screwed in its centre to a bracket H. The skate
stock is hollowed out a little at a, a¹. I thus form a drawing-room
skate with three rollers, one in front and two behind, united by a steel
spring, which allows an easy twisting motion for curves or other
evolutions.
Figure 3 is a plan; Figure 4, an elevation of another mode of con-
structing drawing-room or roller skates according to my Invention.
A is the skate stock; B, B', the frames which hold the axles of the 2
front roller C and double-back rollers C¹, C". These frames are each
fixed to flat steel springs D, D¹, screwed to the skate stock A over two
parts cut out at E and E', the space being filled up by a sheet of india-
rubber F, F, if found desirable; the skate stock A resting on the flat
steel springs D, D', allow an easy twisting motion being given, whereby a
great facility for making curves or other evolutions.
I would remark that for persons skilled in skating two rollers, one at
back and one at front, with my improved steel springs, would answer
well.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 3
filed by the said Henry Malcolmson in the Great Seal Patent Office
on the 7th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
MALCOLMSON, of 5, Southampton Buildings, Holborn, in the County of
Middlesex, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of May, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Malcolmson, Her special
licence that I, the said Henry Malcolmson, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Malcolmson,
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 Invention for
"IMPROVEMENTS IN DRAWING-ROOM OR ROLLER SKATES," upon the condition
(amongst others) that I, the said Henry Malcolmson, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was.
to be performed, and cause the same to be filed in the Great Seal' Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Malcolmson, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :—
This Invention consists in constructing drawing-room or roller skates
in such a manner that curves and other evolutions may be performed
with more ease than heretofore by constructing them with three rollers
disposed as hereafter described, and adapting steel springs to skates
constructed with two or more rollers. The illustrative Sheet of Drawing
which accompanies this description shows the manner by which I propose
to obtain the above object.
Figure 1 is a plan; Figure 2, an elevation of a drawing-room or roller
skate constructed according to my said Invention. In each of these
views similar letters are used to denote corresponding parts.
A is the skate stock; B, B¹, two brackets fixed thereto; C is a franie
which serves to hold the axle D of the front roller E. This frame is
provided with a. spigot F, which passes through a circular hole in the

page_text: bracket B. This spigot is slit at f. C' is another frame for the axle of
the two rollers E¹, E", kept asunder by means of the collars e, e¹, and
arm c. This frame is also provided with a spigot F', which passes
through a circular hole in the bracket B'. This spigot is also split in f¹.
The spigots F, F', are united by means of a flat steel spring G, which fits
into the split parts f,f¹, and is held therein by means of pins or rivets g.
This flat spring is screwed in its centre to a bracket H. The skate stock
is hollowed out a little at a, a¹. I thus form a drawing-room skate with
three rollers, one in front and two behind, united by a steel spring, which
allows an easy twisting motion for curves or other evolutions.
Figure 3 is a plan; Figure 4, an elevation of another mode of con-
structing drawing-room or roller skates according to my Invention.
:
A is the skate stock; B, B', the frames which hold the axles of the
front roller C and double back rollers C¹, C. These frames are cach
fixed to flat steel springs D, D¹, screwed to the skate stock A over two 1
parts cut out at E and E', the space being filled up by a sheet of india-
rubber F, F, if found desirable; the skate stock A resting on the flat
steel springs D, D', allow an easy twisting motion being given whereby
great facility for making curves or other evolutions.
Figure 5 is a side elevation showing a four-roller skate attached to the 2
foot by means of straps; Figure 6 is a sectional elevation of this skate,
in which the frames C; C¹, for supporting the axles D, D¹, of the rollers
are fixed to the blocks K, K', passing through the brackets B, B', and
attached to the spring G, which in this case is placed vertically instead
of horizontally, as in Figures 1, 2, 3, and 4. A back view and plan of 2
this skate are shown at Figures 7 and 8.
Figure 9 is an elevation; Figure 10, a plan of a three-roller skato
with spring placed vertically. In this case the two back rollers arc con- .
nected with the spring in the same way as in Figures 5, 6, 7, and 8, but
the front roller is connected thereto by a frame C having a spigot F3
passing through a bracket B¹ shown in detail at Figure 11.
I would remark that for persons skilled in skating two rollers, one at
back and one at front, with my improved steel springs, would answer
well.
Having now described and set forth the nature and object of my said a
Invention for "Improvements in Drawing-room or Roller Skates," I

page_text: would remark in conclusion that I hereby declare my Invention to consist
n, and I claim, adapting steel springs to drawing-room or roller skates,
also the construction and arrangement of such skates, substantially as
described and represented.
In witness whereof, I, the said Henry Malcolmson, have hereunto
set my hand and scal, this Fourth day of November, in the
year of our Lord One thousand eight hundred and seventy-
four.
