COMPLETE SPECIFICATION.
Improvements in Mechanical Slides for Purposes of Recreation.
We, EDWIN APPLEBY, of 92, Thornhill Road, Handsworth, in the County of
Stafford, Corn Factor, and ALFRED CHARLES THOMAS, of 58, Lodge Road, Hock-
ley, in the City of Birmingham, Designer, 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 reference to mechanical slides of the kind described in the
specification in connection with our prior application for Letters Patent No. 1617
dated 24th January 1899. In our said prior invention the stationary axles on which
the tubular rollers turn are carried in slots in the frame or sides of the track. After
continual use it is found that these slots are liable to wear and then the axles
of rollers are not parallel with one another.
Our present invention is designed to overcome these defects and to simplify
the construction of the slides and is carried out as we will describe by referring
to the accompanying drawings on which Fig. 1 is a side elevation partly in
section of a roller slide constructed according to our present invention; Fig. 2
is a plan of the same; Fig. 3 is a cross sectional elevation of the same; Fig. 4
is a plan and Fig. 5 is an elevation partly in section of parts of the said roller
slide; l'ig. 6 is a cross section of one of the wooden sides of the slide; Fig. 7
is a side view of a part of a modified form of the said slides; Fig. S shews separ-
ately one of the sheet metal links; and Fig. 9 shews a slightly modified form of
the same.
The same letters of reference indicate the same parts in all the figures of the
drawing.
AA are the tubular rollers which are free to revolve on the stationary axles B
as described in our prior specification.
In carrying out our present invention the wooden sides C₁ C of the roller
track are both rebated at e¹ from end to end to receive the end portions of
the axles B the depth of the rebates being a little less than the diameter of the
axles B and extending for a convenient distance say three quarters of an inch
more or less across the width of the wooden side. The vertical side of the rebate
thus forms a stop to prevent the axles moving endways. In order to keep the
axles parallel, sheet metal links D are provided made with holes to receive
the axles so that when threaded on the axles at the ends of the rollers A as repre-
sented in the drawing the links D keep the axles parallel with each other and
at exactly the proper distances apart. The sides CC2 are maintained at the
proper distance apart by cross stays e as in our prior invention above referred to.
Fixed by screws f to the two sides CC are two wooden covering strips G¹G²
between which and the sides CC the ends of the axles are cramped and in order
to effectually grip the axle ends and prevent them from turning, a strip of felt
or other suitable material H is inserted between the strips G2 and the sides C2
to bear upon the axle ends.
Instead of the links being each made with only two holes to take two
roller axles as shown in Figs. 1, 2, 4, 5 and 8, said links may be made long
•

page_text: enough to take three or more of the said axles for instance as shewn in Fig. 9
where the link D is made to take four axles or as shewn in Fig. 7 where the link
is made very long and takes thirty two axles.
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: --
In a roller slide for the purposes of recreation, the combination of a series of
stationary axles laid parallel side by side, side links through which the axles
are threaded to keep them parallel and at the proper distances apart, tubular
rollers adapted to revolve on said axles, two sides CC stayed at the proper
distance apart and related to receive the axle ends and covering strips G 62
fixed to said sides to cover the axle ends, all substantially as set forth.
Dated this 16th day of May 1899.
