page_text: Improvements relating to the Means or Contrivances Employed in
Carrying Out a certain Novel Recreational Game or Pastime.
We WILLIAM STOBBS and EDWARD LLEWELLYN WHITE, both of number 222
Deptford Lower Road, London, S.E. Domestic Engineers do hereby declare the
nature of this invention to be as follows :-
Our present Invention has reference to and is based upon that dated 18th May
1885, No. 6068 for which Letters Patent were granted to us in due course, namely
for "A novel combined arrangement of structural and mechanical devices and
appliances for, and means or contrivances to allow of, the introduction and carrying
out of a novel recreational game or pastime."-Said game or pastime being, as stated
in the Specification of our Invention of prior date hereto, above referred to, that
designated "Tobogganing."
The improvements, in our present Invention, are comprised under two heads :—that
is to say-The improvement under the first head has reference to the "runs,"
channels, ways or tracks into which the inclined plane, referred to in the Specification
of our Invention No. 606885, is divided.-Said improvement consists in the width of
the "runs," channels, ways or tracks aforesaid being decreased by the contraction of
the dividing ridges towards the foot of the inclined plane so to form as it were
a Bottle-Neck-like contraction at this part, the object being to check the speed or
momentum of the Toboggan as it reaches the foot of the inclined plane aforesaid; the
reduction in speed being effected by the Toboggan running against the ridges at the
neck or contracted portion aforesaid, with the resultant friction gained.
The improvement under the second head of our present Invention, has reference to
the means provided in accordance with our Invention No. 606885, to allow of the
return of the empty Toboggans or sledges up the incline to the starting point. Said
improvement consists in adapting either by securing or jointing at suitable intervals
to the endless hauling up rope-preferably a flat rope of steel, or other wire, or
other suitable material or materials a series of carrier brackets preferably pieces of
angle iron, which on their running round the drum or pulley at the base of the incline
are brought into contact with and clutch or catch the Toboggan or sledge, and thus
serve to carry up same by means of the endless working rope, to the summit of the
inclined plane.

We WILLIAM STOBBS and EDWARD LLEWELLYN WHITE both of 222 Deptford
Lower Road, London, S.E. Domestic Engineers, 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 :-
Our present invention has reference to, and is based upon that dated 18th May 1885
No. 6068, for which letters Patent were granted to us in due course, namely in respect
of "A novel combined arrangement of structural and mechanical devices and
appliances for, and means or contrivances to allow of the introduction and carrying
out of a novel recreational game or pastime." Said game or pastime being as stated
in the specification of our Invention above referred to of prior date hereto, that
designated "Tobogganing."
"
The improvements in accordance with our present invention are illustrated in the
accompanying sheet of drawings and are comprised under two heads, that is to say :-
The improvements under the first head or feature has reference to the
runs,"
channels, ways or tracks into which the inclined plane referred to in the specification
of our invention No. 6068 is divided. Said improvement consists in the width of
the " runs channels, ways or tracks A. Figure 1., above mentioned, being
decreased, by the contraction of the dividing ridges near the foot or bottom of the
inclined plane, so as to present as it were a bottle-neck like formation at that part as
shown at a; the object of such contraction being to check the speed or momentum of
the Toboggan as it reaches the foot of the inclined plane aforesaid, the reduction in
speed being effected, as will be seen on reference to the drawings, by the Toboggans
running against the ridges at the neck or contracted portion aforesaid, as shown
at cc with the resultant friction which ensues and the consequent retardation in the
speed of the descending Toboggan.
Under the second head or feature of our present invention, the improvement refers
to the means provided in accordance with our invention No. 606883 to allow of the
return of the empty "Toboggans" or sledges up the inclined plane to the starting
point, and consists in the adaptation-by securing at suitable intervals to the endless
hauling up rope B figure 2, preferably a flat rope of steel or other wire Figure 3. or
other suitable material or materials, of a series of carrier brackets preferably pieces
of angle iron, as illustrated at b. b. b. figure 2. which upon their being carried round
the drum or pulley c. at the foot of the incline are brought in contact with and clutch
or catch the "Toboggan" or sledge and thus serve to carry same up to the summit of
the inclined plane.

page_text: Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we declare that what we claim is :-
Firstly. In an artificial Toboggan slide, the contraction of a portion of the "runs,"
channels, ways or tracks, substantially as and for the purpose herein described and
set forth.
Secondly. In connection with the devices employed for hauling up the Toboggans
of an artificial Toboggan slide, the use of carrier brackets, substantially as herein
described and set forth.
